The invention in General relates to the field of panels with mechanical systems block containing a separate flexible comb, providing easy setting. The invention provides a new and improved blocking systems and methods setting for building panels, especially floor panels.

In particular, it is still not a limiting manner, the invention relates to a mechanical blocking system for rectangular panels with long and short edges. It should be emphasized that the long and short edges are only used to simplify description. The panel may also be square, they can have more than 4 edges, and adjacent edges may have angles different from 90 degrees. However, the invention is also applicable to construction panels at all. More specifically, the invention relates to the type systems of the mechanical blocking, which provide the possibility that all four edges of the panel could be locked with other panels via a single action reversal containing bent, and/or shifting and/or rotating comb, to facilitate the setting of the building panels.

The floor panel of this type is presented in the publication WO2006/043893, which opens the panel is of uretrite system block, containing a blocking element cooperating with the locking groove for horizontal block, and bent ridge interacting with the groove in the ridge for locking in the vertical direction. Flexible comb is bent in the horizontal plane during the joining of the panels and makes it possible to install panels with vertical folding or solely through vertical movement. The phrase "vertical stacking" assumes the accession of three panels, where the first and second panels are in the attached state, and where the only effect of the reversal of the new panel, referred to as "folding panel, simultaneously attaches two perpendicular edges of the new panel to the first and second panels. Such accession shall be effected, for example, when the long edges of the first panel in the first row is already attached to the long edge of the second panel in the second row. Then a new folding panel attached by reversal to the long edge of the first panel in the first row. This particular type of action reversal, which also attaches to the short edge of the new folding panel and the second panel, referred to as "vertical stacking". Short edges are in General attached horizontally with the aid of the people of the strap, containing a blocking element on the panel strip, and a locking groove on the lower part of the folding panel that interacts with the blocking element panel trims. You can also attach two panels, lowering the entire panel through an exclusively vertical movement relative to the other panel. This particular type of block is referred to as "vertical block".

Such slabs are additionally described in WO2003/016654, which discloses a system block containing comb with flexible foot. The ridge continues and is bent essentially in the vertical direction, and the upper part of the foot interacts with the groove under the crest of the vertical block.

Vertical blocking and vertical folding of this type create pressure separation on short edges when bent comb or bent part of the crest displace horizontally in double action during the reversal of the long edges. Part of the crest move inside during the initial part of the block, and then they are shifted to the original position during the final portion of the actions block. The inventor has analyzed several types of panels and found that there is a significant risk that the short edges can push off from each other lying in the setting and that may form between the parts of the edges and short edges. This period can prevent further settlement, and the floor slabs will be unable to connect. It can also cause serious damage to the system block on short edges. Boost flooring boards in the direction to the short edges during setting can prevent the formation period. However, this method of setting is complex and difficult to use, since they need to be combined and used simultaneously three actions in connection with the reversal down the long edges, as described below.

a) the Edges of the new panel overlap must be brought into contact with the first slab lying on the floor and on the long edge of the new panel should push forward at an angle to the first panel.

b) a New panel should be shifted sideways, down and tilted up position, and push it sideways relative to the short edge of the second panel, lying on the floor to oppose the counter-pressure ridge.

c) Finally the new panel should be deployed down to the slab, and during the reversal should maintain pressure forward and sideways.

It was found that the separation problem and the setting often occur when the panels have a small thickness and a small compact system block long the edges or when the core of the panel is made from a material with smooth surfaces, such as wood-fiber Board, high density fiberboard (HDF). Such problems can also occur when the panel is short or in connection with setting up the first or last panel in each row, since this setting is performed in common with panels that are cut to a smaller length, in order to adapt the overlay to position the wall. Of course, the problem of separation is extremely difficult to manipulate in any type panels using blocking systems with a strong bent ridge, which creates a substantial horizontal pressure separation during the vertical folding. Such strong ridges are very important in many applications where a vertical joining of high quality, and panels with flexible ridges very difficult to establish using known methods of setting.

The invention seeks to solve the problems of separation of floor coverings, which are intended for setting with vertical folding or vertical block, or only maximize the long edges.

Vertical folding in accordance with known technology blocks panel vertically when they are tilted down. The panel can be unlocked. This can be done by using special tools that insert into the system lock is for. You can also tilt up the whole series and disconnect the panel from each other. It would be useful if the individual panel can be locked and unlocked more easy way, preferably using simple reverse turn. Damaged panels or incorrectly installed panel you can adjust, replace or re-install.

Therefore, another object of the invention is to provide a solution to this problem using a new system block, after which the vertical folding is not attached vertically and which can be released with a simple turn in the opposite direction.

Vertical folding in accordance with known technology requires that some parts of the system blocking bent, flexed or moved when the panels are tilted down. This creates resistance, which is a disadvantage during setting. The third objective of the invention is to provide solutions that avoid such resistance to the maximum extent possible and in which preferably all types of resistance caused by the vertical locking parts during the vertical folding is significantly reduced or completely eliminated.

Different types of flooring boards require different solutions b is Ocharovanie. System lock adapted for locking floor coating of thin layered material thickness 5-8 mm with a core of HDF, it is not always possible to use for blocking, for example, thick wooden floor coating with a thickness of 14-25 mm and heartwood of various rock types and qualities of wood. The fourth goal is to provide solutions suitable for a wide range of different types of floors, and different sizes of the same type overlap.

The definition of some terms

In the subsequent text the visible surface of the installed panel overlap is called the "front surface", while the opposite side panel overlap, turned to the black floor, called the "rear surface". The edge between the front and rear surface is called "connecting edge. Unless otherwise specified, the "above" and "below" means "front surface" and "back surface". "Internal" and "external" means "to" or "from the center panel. Under the "horizontal plane", it is assumed the plane, which continues parallel to the outer part of the surface layer. Located directly next to the upper parts of two adjacent connecting edges of two interconnected panels define a "vertical plane", perpendicula the ing the horizontal plane. By "horizontally" assume "is parallel to the horizontal plane", and "vertically" assumes "parallel to the vertical plane".

Under "connection" or "system blocking" is assumed, acting together attaching means that attaches the panel overlap vertically and/or horizontally. Under "system mechanical lock", it is assumed that the connection can be made without glue. System mechanical blocking in many cases can also be combined with bonding. Under the "made in one piece with it formed as a single whole with the panel or attached to the panel in the factory". Under the "separate" parts, components and similar components assume that they are made separately and not as one whole with the core or main body panel. Separate parts in General attached at the factory and made in one piece with the panel, but they can be provided as lost parts that are intended for use during the setting panel.

Under the "flexible comb is expected to separate the crest, which has at least some of the bent part and which has a longitudinal direction along the connecting edges, and which way the t piece vertical locking system. The entire comb may be, for example, bendable, or it may be flexible and elastic parts that can be bent and/or compressed, and it can, at least partially, to go back to or towards its original position. Flexibility makes the comb while blocking the move, at least partially, in the horizontal direction. The term "bent ridge" in this document is widely used, because most of the shown embodiments have at least some bent parts. The invention does not exclude bent ridge, which is essentially or partially made of a rigid material.

Under "shifting crest is expected any type of comb that attaches adjacent edges vertically and which is made of a single material and attached to the panel overlap, and which may wholly or partly be moved between an unlocked position and a locked position. Move the comb may be flexible or rigid.

Under the "crest" assumes any part of the section edges, which prevents the vertical offset.

Under the "reversal" is supposed connection formed by rotational motion, during which there is a change in angular position between the two parts that Pris is United by or disconnect. When the reversal relates to the joining of two panels overlap, is the angular displacement from the upper parts of the connecting edges at least partially in contact with each other during at least part of this movement.

Under the "reversal system blocking" it is assumed the system is a mechanical lock that can be attached vertically and horizontally using spread that the ridge and groove that locks the two adjacent edges in the vertical direction, and the locking bar from the locking element at one edge of the panel, called "bar bar", which interacts with the locking groove in the other edge of the panel, called "the panel grooves, and block edges in the horizontal direction. The locking element and the locking groove have in common rounded guide surfaces which guide the locking element into the locking groove, and the surface of the block that block and prevent horizontal separation between the edges.

Vertical folding is not a pure combination of, for example, reverse blocking systems on long edges and a vertical block on short edges as vertical and turning actions of the joint, and the short side of the IC is adivay together in the same way, as scissors. Blocking occurs gradually from one section of the edge adjacent to one long edge, which is inclined to the other sections of the edges adjacent to the opposite long edge. Such blocking of the two adjacent edges is defined as "locking folding".

"Vertical stacking" is a block of three panels, which uses a combination of turn on long edge and fold the short edges. Under "vertical fold along the vertical plane is expected vertical folding with the upper edges of the two short edges being essentially in contact essentially within just steps of folding up until edges are not locked together.

The present invention relates to a set of building panels, especially panels overlap, or "floating" floor system mechanical block containing separate the effect of moving the tongue on the short edge, which is configured to improve the setting and detaching the panel overlap, established by vertical folding or spread, and which will counteract or prevent the separation of the short edges during setting.

The invention is based is first and basic understanding of such separation problem associated with the individual shift crest in the block folding, which must be pressed into the groove offset to otskakivat ago in a horizontal direction to the groove ridge during the vertical folding. The purpose of the invention is to provide a locking system that can be locked with vertical movement or spread adjacent edges, and where the power split shift ridge during vertical movement or spread significantly reduced or preferably eliminated due to the fact that inward displacement of the shifting of the ridge in the groove of the movement during setting significantly reduced or completely eliminated.

The invention provides new options for blocking systems on short edges in accordance with various aspects of the offering of benefits. Useful for the invention are wall panels, ceilings, exterior applications and floor panels of any shape and of any material, for example of a multilayer material; especially panel with surface materials, which contain a thermosetting resin, wood, HDF, plywood or stone.

In accordance with the first basic principle of the invention contain what it set panels overlap, contains locking system with a shift of the ridge, made in one piece with the edge of the panel overlap to attach edge vertically to the adjacent edge of a similar panel. Move the comb is configured to be displaced essentially horizontally and essentially in one direction from the initial position to an end of the outer locked position in the groove under the crest.

In accordance with the first embodiment of the invention contains the set of essentially identical panels is provided with first and second connecting elements, and connecting elements made in one piece with the panels and configured to attach adjacent edges. The first coupling element includes a locking bar with an upward locking element on the edge of one panel overlapping and open down the locking groove in an adjacent edge of the other panel overlap for joining adjacent edges in a horizontal direction perpendicular to the adjacent edges, the second connecting element has the effect of moving the tongue on the edge of one panel overlapping and horizontally open groove ridge in the adjacent edge of the other panel overlap for joining adjacent edges in the vertical is upravlenii, moreover, the connecting elements are configured to be blocked with topping or vertical movement. Blocking part of the shift of the comb are made in the domestic original position in the groove of the shift in the edge of the panel. A blocking portion configured to be displaced essentially horizontally and essentially in one direction from the initial position to an end of the outer locked position in the groove under the crest.

One significant difference from the known technology is that at least part of the ridge is displaced essentially in one direction only from the initial unlocked position, where he was attached to the edge in the factory, and in a locked position, where it blocks the edges vertically. Blocking is a "single action latching" or "single action bias". Known flexible and shifting combs first move inside the groove offset, and then outward into the groove under the crest. These two displacements are in General the same value. In some cases, the first offset even more than the second offset, for example, when locking is done with pre-stretching with respect to part of the groove under the crest. Such blocking is a "dual action is amerciana". The main advantage of the single action lock or single action bias is that blocking can be performed without any forces division, which pushes, for example, the short side while blocking and setting.

The expression "essentially in only one direction" means that the invention covered by some embodiments of double-action, and they are not exclusively preferred in such cases where the first shift groove bias is substantially less than the second shift groove in the ridge. The first offset may be used, for example, to release the shift of the crest of his inner unlocked position, or only for part of the shift to an unlocked or partially locked position.

In accordance with the first aspect of the first principle of the invention provides a kit of panels containing locking system with a separate flexible comb, made in one piece with the edge of the panel overlap to attach edge vertically to the adjacent edge of a similar panel. Part of the ridge is made so as to be displaced essentially horizontally and essentially in one direction only from the initial position to the final external locked floor is the taxpayer. The crest is made to curl along the connection while blocking.

In accordance with the embodiment of the first principle, the invention provides a flexible comb having a crank connection with a pressure relief item, continued essentially horizontally from the crank connection, and locking protruding part that extends from crank connection essentially vertically upwards. Blocking the protruding part has a blocking portion in the upper part above the crankshaft connection. The locking part is locked in the groove under the crest, when, for example, on adjacent short edges of the first and second panels press vertically relative to the pressure plate serving items up until a short edges are not placed essentially in the same plane.

Vertical pressing relative to push the protruding part is preferably called by vertical folding.

In accordance with the second aspect of the first principle provided a set of panels containing locking system with a separate flexible comb, made in one piece with the edge of the panel overlap to attach edge vertically to the adjacent edge of a similar panel. Flexible comb contains parts that are under will prefix inim elongation.

In accordance with the embodiment of the second aspect is provided with the panel overlap, for example, with the short edges with locking system with a separate flexible comb, which is blocked with a single action. Vertical movement of one short edge makes part of the shift of the ridge to snap into place essentially in one direction from an internal source unlocked position, where the effect of moving the comb is connected to the groove offset with pre-tension to the vertical locked position. Removing the pre-stretch is preferably called by the vertical folding.

In accordance with a third aspect of the first principle provided a set of panels containing locking system with a separate comb, made in one piece with the edge of the panel overlap to attach edge vertically to the adjacent edge of a similar panel. At least part of the ridge is shifting and blocking performed by lateral pressure applied in the section of the edge of the ridge and essentially along the edge.

In accordance with one embodiment of this third aspect, the invention provides a shift of the ridge, which is displaced in the groove bias. The invention is distinguished those who, the offset shift of the crest of the initial unlocked position, in which it is attached at the factory, and in the groove under the crest is called, for example, a long edge of the third panel, which cant and attached to the first and second panels when they are essentially in the same plane, and with their short edges in contact.

This third aspect provides the possibility that panels are unlocked in the vertical direction until, until it is attached to the third panel in an adjacent row. Vertical fold and detach with turn down and up again can be performed in a simple way, because there is no crest, which creates any resistance and which is locked in the vertical direction. First is triggered by the vertical block when installing a new row of panels. This is the main advantage in comparison with all known folding down systems that have a vertical blocking. Blocking systems in accordance with this principle can be done with a shift of a comb, for example, on the short edge of the panel, which returns to its original unlocked position, when the long edge of the panel in an adjacent row release, for example, using again the company up. This ensures that all the overlap can be disconnected using a simple reversal of the individual panels. When this is not necessary, as using known techniques, to disconnect the whole series with a reversal to disconnect the overlap. Alternatively, the system block can be configured so that flexible (crest) remained in its outward position due to the friction between the comb and the panels or by permanent deformation of the ridge, even if the third panel is removed.

All these three main variants of implementation, where the offset is called:

a) by pressing push the protruding part,

b) removing the pre-stretch

c) and offset of the ridge on the short edge with the long edge,

based on the main principle that the offset is essentially in one direction only, and that this shift may be performed only with very limited or negligible forces of separation.

The above aspects have been described with panels having long and short edges. The panel may have more than four edges, and they can be square.

In accordance with the second principle of the invention provides a method of setting and removing panels is the reversal system block, for example, on the long edges and shifting crest on short edges. The method comprises the steps:

1. Join the long edges of the second and the new panel in the second row to the long edge of the first panel in the first row so that the short edges of the second and the new panel in the second row are in contact and essentially in the same plane.

2. Attach the third panel in the third row with a reversal to the long edges of the second and new panels, whereby a shift of the tongue on the short edge of the second or new panel is displaced into the groove under the ridge so that the short edges are locked vertically and horizontally.

In accordance with this second principle, the invention provides a method for detaching the panels overlap with the reversal system block, for example, on the long edges and shifting crest on short edges which attach the panel overlap vertically. The method comprises the steps:

1. Detach the long edges of the third panel in the third row from the long edges of the second and the new panel in the second row and detach the shift of the ridge and vertical blocking between the new panel and the second panel in the second row with a reversal up the third panel from the black floor.

2. Detach the new panel from the long edges of the first panel in the first row and from short chrome is to the second panel with turn up.

In accordance with the third principle of the invention provides panels and blocking systems with a horizontal bent or shifting of the blocking element, which provides the ability to attach a panel using a horizontal offset to each other essentially in a common plane in accordance with the same basic principles that were used for vertical folding, as described in this document. The blocking element is displaced vertically and locked in a horizontal direction in the locking groove located at the top or bottom top or bottom flange. The locking in the vertical direction is preferably performed using a ridge and groove. This third principle is described herein only schematically, since all options for implementation and principles that are used for vertical block can be used for horizontal blocking. It is obvious that parts that interact in a horizontal direction, should be adjusted in the vertical direction, etc.

The second objective of the invention is to provide a new and improved ways to implement a separate flexible ridges that can be used in all types of systems block where you want the offset at least part of the Greb is I, to enable vertical or horizontal blocking panels. The aim is to improve the functioning of the blocking and the blocking strength compared with the known technology.

The invention provides a flexible comb having a longitudinal direction. At least one of the edges, continuing in the longitudinal direction, is hard. Flexible ridge is in the longitudinal direction of the one or more elastic cavities that can be compressed and to go back to the original position.

The invention is useful in all types of floor coverings and particularly floor coverings, where it is difficult to prevent separation, for example, due to friction between the long edges, or where the famous combs create large forces of separation. Therefore, the invention is particularly suitable for short panels, for example, 40-120 cm, where the friction along the long edges of the low, wide panels with a width of more than 20 cm, known as flexible ridges are long and create a strong pressure ridge and panels, for example, with a core of HDF, compact laminated or plastic materials, etc. where the friction is low due to the very smooth and low friction surfaces in the system block. The invention is also useful in thin panels, for example, with a thickness of 6-9 mm, and especially in such panels, which have a compact system block on the long edges, for example, blocking laths less than 6 mm, such as slabs and such a system block will have a small contact surface with low friction.

Using system flooring, made in accordance with one or more of the above principles can be achieved several advantages. The first advantage is that the setting can be performed in a simple way and without the necessity of applying lateral pressure during setting to prevent separation of the boards at the short edges. The second advantage is that significantly reduced the risk of separation of the edges, which can cause cracks in the system block during folding. The third advantage is that the system lock can be formed from more rigid and more durable crests, which may block panels vertically with higher strength. The fourth advantage is that the locking and unlocking can be done easier and more reliable operation of the lock.

The ridge may include a plastic material and can be manufactured, for example, whether through the article under pressure. With this manufacturing method can produce a large variety of complex three-dimensional shapes at low cost, and flexible combs easily attach to each other to form a billet of the ridges. The comb can also be made from pressure-treated or subjected to mechanical processing of plastic or metal sections, which can be additionally formed, for example, by stamping, to form a bent comb. The disadvantage associated with pressing, in addition to additional stages of manufacture, is that is difficult, but not impossible, to strengthen the crest, for example, fiber. However, molded plastic section may be the preferred alternative when the ridge has a cross-section is essentially rectangular in shape. Based on the wood material, such as HDF, or compact multilayer material, or plastic material in the form of a sheet, may also be used to form a bent or offset of the ridge.

You can use any type of polymeric materials, such as PA (polyamide), POM (Polyoxymethylene), PC (polyacrylonitrile), PP (polypropylene), PET (polyethylene terephthalate) or PE (polyethylene), or a similar material having the properties described above in various embodiments of implementation. These angular end is sovie materials, when, for example, using injection molding, can be strengthened, for example, using fiberglass, fiber Kevlar, carbon fiber or talc or chalk. The preferred material is glass, preferably extra-long, reinforced PP or POM.

Short edges can be removed with a tool in the form of a needle that can be inserted from the bend in the groove under the crest and pressing the flexible comb back in the groove bias. Then one panel, you can deploy up, while the other panel is still on the black floor. Of course, the panel can be removed in the traditional way by reversal up or offset along the connection

Almost all the variants of implementation described with separate crests panel trims mainly in order to simplify the description. Separate comb can be located on the edge of the folding panel.

Panel 1, 1' overlap prior art, equipped with a mechanical lock and bent ridge 30 described with reference to figa-1d.

On figa schematically shows a cross-section of the connection between the connecting edge 4a of the short edges of the panel 1 and the opposite connecting edge 4b of the short edge of the second panel 1'.

The front surface of the panels is placed essentially in a common horizontal plane HP, and the upper part 21, 41 of the connecting edges 4a, 4b against each other in the vertical plane VP. The mechanical blocking system ensures the locking of the panels relative to each other in the vertical direction D1, as well as in the horizontal direction D2.

To ensure the connection of the two connecting edges in the directions D1 and D2 edges of the panel overlap method, which is known in itself, have a locking bar 6 with a locking element 8 on one of the connecting edge, hereinafter referred to as "panel slats, which interacts with a locking groove 14 in the other connecting edge, hereinafter referred to as "folding panel, and provide horizontal blocking.

System mechanical blocking of the prior art with which contains a separate flexible comb 30, fixed in the groove 40 offset formed in one of the connecting edges. Flexible ridge 30 has a section P1 of the groove, which is located in the groove 40 offset, and the protruding section P2, protruding beyond the grooves 40 offset. The protruding section P2 bent ridge 30 on one of the connecting edges communicates with the groove 20 under the ridge formed in the other of the connecting edge.

On figa shows cross section A-A panel in accordance with fig.3b, visible from above. Flexible ridge 30 has on one of the sections of the edges of the friction connection 36, which may be formed, for example, in the form of local small vertical ledge. This frictional connection supports flexible ridge in the groove 40 of movement during setting, or during manufacture, packaging and transportation, if bent comb made in one piece with the floor panel in the factory.

On figa and 2b shows the position of the bent ridge 30 after the first offset to the bottom of the groove 40 offset. The offset is caused essentially by bending flexible ridge 30 in its longitudinal direction by means of folding panels, and this bending creates a force separation, which can cause long edge of the slide, and the short edges to be separated at the time when ladymania.

Figure 4 shows one way of implementing vertical folding. The first panel 1" in the first row R1 is attached to the second panel, 1 in the second row R2. The new panel 1' is moved to its long edge 5a to the long edge 5b of the first panel 1" at a normal angle setting, constituting approximately 25-30 degrees, pressed against the adjacent edge and add to its long edge 5a to the long edge 5b of the first panel with a reversal. This action spread also connects the short edge 4b of the new panel 1' short edge 4a of the second panel 1. Folding panel 1' is locked to the panel 1 of the strap with the combined vertical and rotational movement along the vertical plane VP and the contact between the upper edges of the second panel 1 and the new panel 1'.

On figa-5c shows the known examples of flexible ridges 30 that can be used to lock the short edges in accordance with known technology. Figa shows the individual ridge 30 on the panel bracket with a flexible snap-on foot, continuing down. Figs shows the individual comb with a flexible snap-on foot within grooves 40 offset. Snap-on presser foot can go up or down and can be on the panel, lath or folding panel. Figs shows bent ridge 30 that contains the tabs 60, as the show is but fig.5d, these protrusions may be located in the groove 40 offset or continue from the vertical plane in the groove 20 under the crest. All of these options for creating pressure P of separation, when the bent part of the crest vimutta inside to the bottom of the groove offset, and this may cause the short edges to be separated so that the system lock can be damaged, or so that the bar cannot be set.

On figa-6d illustrates embodiments of the panels with blocking in accordance with the first aspect of the invention. Panel 1 of the strap has a locking bar 6 with a locking element 8 and the bent ridge 30 which is attached to the groove 40 offset. Flexible ridge 30 has a crank connection 15 with the lower pressure relief item 17 continued essentially horizontally beyond the vertical plane VP containing push the locking element 18. Crankshaft connection also has a locking protruding part 16, continued essentially vertically, with the locking part 19 in the upper part of the locking protruding part 16. The folding panel 1' has a locking groove 14, which interacts with the locking element 8 and locks the panels horizontally, and push the locking groove 10, which communicates with the pressure of the blocking element of the om 18 and prevents the horizontal offset between the folding panel 1' and shift the locking element 31. The folding panel 1' also has an installation groove, which interacts with the locking part 19 and blocks panel 1, 1"vertically. Push the protruding part 17 will bend down with pressure locking element 18 is locked in the pressure locking groove 11 when the folding panel 1' is moved vertically down to the panel 1 strap essentially along the vertical plane VP, as shown in fig.6b and 6c. The blocking portion 19 in the end will snap into place in the groove 20 under the crest, when the upper part of the connecting edges 21, 41 will be essentially in the same horizontal plane, and panels 1, 1' will be locked vertically D1 and horizontally D2 without any horizontal pressure, which can displace edges from each other during the vertical folding. Bending the push protruding parts 17 and flexibility bent ridge 30, which provides the opportunity to push the protruding part and the blocking part to be separated, at least slightly, from each other while blocking, are the essential feature that provides the ability to block high quality with the upper edges located in a common plane. System block in accordance with the invention is a vertical locking system. Greben is during the vertical folding will curl in the longitudinal direction. Edge, which is close to the long side, which is associated with a reversal (4b1 figure 4), during the vertical folding will be in the position as shown in figs, while the other edge (4b2 figure 4) will be in the position as shown in figa. Bend push the protruding part 17 will vary along the length of the ridge 31. Even a small bend of approximately 0.1 mm, can significantly improve the performance and quality of the block, and provides the opportunity to significantly reduce or preferably eliminate the gaps or vertical clearance.

On figa-7c shows a flexible combs. On figa shown bent ridge 30, which may be made, for example, by pressing. On fig.7b shows an implementation option, which can be manufactured through a combination of extrusion and mechanical forming process, such as stamping or cutting. Part of the lower protruding part 22 can be removed to increase the flexibility and torsion of the lower protruding parts. This means that the length LP pressure serving items will be variable along the bent ridge 30. Figs shows another variant implementation, which is made by injection molding. Blocking the protruding part and push the protruding part have holes 24, 23, or in the quality of the solid fuel alternatives thinner sections that promote flexibility, since the torsion in the longitudinal direction of shift of the comb may be used to make parts more flexible, at the same time maintaining the strength of the block. This means that the thickness of the blocking part of the TL, and/or blocking protruding parts TE, and/or push the protruding part TP may change along the bent ridge 30.

Within the main principle of the invention there are several alternatives. Push the locking element 18 may also have continuing down the ledge 18' so that it can be locked in the locking groove 14'located on the upper side of the strips 6, like the version of the implementation shown in figa and 11f. Horizontal blocking can be performed without the use of a large blocking element 8, and this may provide a lower cost with less waste and opportunities to use the invention in a very thin coating of floors, for example, thinner than 7 mm, Push the protruding part 17 may have a different length, and it may cover part or even all of the blocking element 8, as shown by the dotted lines on fig.6d.

On figa-8d shows a variant implementation in accordance with the second aspect of the invention. Flexible graebe is ü 30 has an inner unlocked position and the outer locked position. Flexible comb 30 is in its unlocked position, is fixed in the groove offset, pre-stretching, caused by, for example, part 51 is bent ridge, which presses on the flexible comb 30 upwards. Horizontal latch 52 crest on the flexible comb 30 communicates with a horizontal locking grooves 53 in the groove 40 offset and prevents skipping bent ridge 30 to its final locked position. The latch grooves can be formed with different angles. For the formation of surfaces with large effect angles can be used, for example, the scraper. Flexible ridge jumps in the locked position where the locking part 19 is locked in the groove of the shift, when the upper part 21 of the short edges on the folding panel 1' moves the bent part of the ridge down and separates the horizontal crest and the latches 52, 53 of the groove, as shown in fig.8b, 8c. You can use several options with various forms of flexible parts, by means of blocking and means separation to create a preliminary stretching bent ridge, blocking ridge in the groove offset and bent to release the comb so that it jumped to its locked position. With busiest parts can be made from the same material, as bent crest, or from a separate flexible material attached to the ridge or the groove bias. The horizontal force separation in General are not present in this type of action is the only place where the ridge is displaced essentially in one direction. Even in the case when the pre-tension can be removed when the lock folding blocked partially, the problem of the division will be reduced because of the blocking element 8 panel strap is partially blocking the groove 14 of the folding panel and prevents separation. This is shown in fig.8b.

On figa shows a variant implementation of the bent ridge, seen from above, and fig.9b shows the same variant implementation, visible from the edge of the panel parallel to the horizontal plane. The protrusion 51 is a flexible part that continues horizontally and vertically, and can therefore press the bent ridge in both directions, to block flexible comb with pre-stretch and shift it to the final locked position.

On figs and 9e shows a variant of the third aspect of the first principle, visible in the same way as described above. Provided the effect of moving the comb that has one or more essentially l is ing lugs 60 with a friction connection 36, entrenching effect of moving the comb 31 fixed in the groove 40 offset. Move the comb 31 will be displaced from its locking part 19 in the groove offset from the rotational movement essentially around a frictional connection on the ledges, when put side pressure P to push the edge 32 to move the comb, as shown in figa. This rotational movement will also shift a shift of the ridge in the groove 20 under the crest. You can use several other alternatives to get the offset by using lateral pressure. Move the comb may be combined with one or more separate wedge-shaped elements, which can be used to shift and push the shift of the ridge in the groove of the comb when the comb or a single item move to the side. Other alternatives are shifting combs with parts that secure the ridge in the groove displacement during transportation and which are designed to separate from the crest, when put side pressure. Of course, you can also use the well-known crest in the shape of an arc, as shown in fig.3b. Lateral pressure will bend the comb, and the protruding part P2 will be displaced perpendicular to the longitudinal direction of the ridge. For shifting the blocking portion in the groove rowed the HB is possible to use all known principles, using lateral pressure to perform perpendicular offset. All options for the implementation shown in this paper are based on the following three principles:

- the principle of communication, where to perform the offset is turning around a Central point;

- the principle of the wedge, where two wedge slide relative to each other;

- the principle of bending, where the parts are bent in the shape of an arc.

These three principles can be combined, and the effect of moving the comb may have a part that uses the principles of communication, wedge and bending to convert the lateral pressure in the perpendicular offset to bring part of the ridge in the groove and block boards flooring vertically or horizontally.

This third aspect of the invention offers the advantage that all parts move the comb can be made hard. However, in some applications, preferred are flexible combs or bent parts.

On fig.9f shows an implementation option, where the push flange 32 on display at the long edges 5b of the second panel 1, which is attached to the first panel 1". The new panel 1' is attached with a reversal to the long edge of the first panel 1" and laid flat on the black floor so that the short edges 4a, 4b of the second and the new panels are in the same plane. T is ETLA panel 1A, as shown in Figg can now be attached with a reversal to the long edges 5b of the second 1 and the new panel 1'and push the edge 32 can be pressed down inside along the short edge of the second panel 1, for example, the ridge 10 of the third panel 1A. Now move the comb 31 will be displaced along the short edges, but also in the groove 20 under the crest of the new panel 1'and the second 1 and the new panel 1' will be locked horizontally, and the risk of separation of the edges while blocking is eliminated. This method of setting and system block additionally explained on figa-10d. On figa shows how the comb 10 clicks on the section 32 of the edge in the direction along the short edges during the reversal of the long edges. On fig.10b shows the locked position with a shift of a crest in its final locked position. While blocking ridge can create significant pressure on a pressure edge and short edge can be rigidly locked relative to each other in the vertical direction. On figs shows the position of the second 1 and the new panel 1' before their short edges are locked vertically and fig.10d shows the locked position, when the crest of the third panel 1A him move the comb 31 is shifted into its final locked position.

Obviously, h is on the crest may be shifted by pressure relative to the pressure edge, that the installer puts in the time setting, for example, a tool, and not by reversal of the third panel. It is also clear that the effect of moving the combs can be attached to the edge of the panel during setting.

The invention provides a method of setting the panels overlap with reverse blocking systems on the long edges and shifting of the crest on the short edges.

The method comprises the steps:

Join the long edges of the second 1, and the new panel 1' to the long edge of the first panel 1" in the first row R1 so that the short edges of the second and the new panel in the second row R2 are in contact and essentially in the same plane.

Attach the third panel in the third row R3 with a reversal to the long edges of the second and new panels, whereby a shift of the tongue on the short edge of the second and the new panel is shifted so that the short edges are locked vertically and horizontally.

The invention provides a method of detaching the panels overlap with the reversal system block on the long edges and bent crest on short edges, as shown in fig.10d and 10c. Flexible ridge 30 may be bendable so that it returns to its original unlocked position when the lateral pressure P is removed, as shown, for example the EP, on fig.14f-14h. The panel is installed and locked, as shown in fig.10d. The method, which includes the following step described with reference to figs.

The method comprises the steps:

1. Detach the long edges 5a of the third panel 1A in the third row from the long edge 5b of the second 1 and the new panel 1' in the second row and detach the flexible ridge 30 and the vertical locking between the new panel 1' and the second panel 1 in the second row with a reversal of the third panel 1A from the black floor.

2. Detach the new panel 1' from the long edges 5b of the first panel 1" in the first row and from the short edges 4a of the second panel 1 by reversal up the new panel 1'.

All three principles of communication, wedge and bending can be reversible.

Figa-11d are examples that show that all embodiments of shifting and flexible ridges can be adjusted so that they, alternatively, may be attached to the opposite short edge to the folding panel. From the drawings it is evident that the effect of moving the comb 31, as shown in fig.9f, may be connected in the groove offset on the new panel 1', which is folded relative to the second panel, 1 plate. On figa shows that push the protruding part 17 may be continued downward pressure of the blocking element 18', which is blocked in the block of yuusei the groove 14', located on the upper side of the strips 6. The dotted line shows that the strap can be made shorter.

Five-11g is an example that shows that the basic principles of offset of the ridge and its functioning and geometry can be used to attach the panels overlap vertically with essentially horizontal single action lock. An implementation option shows the flexible locking element 61, which is fixed in the groove with pre-tension and is released during the horizontal displacement of one edge of the panel relative to the other edges of the panel. All variants of implementation in accordance with the described principles of blocking and disconnection of the panels can be used to attach and detach the panels horizontally in accordance with the same principles that have been shown to vertical folding. Obviously, all shown bent or offset combs can be used as flexible or shifting of the locking elements 61, which can be shifted vertically instead of horizontal displacement in the locking groove 14. A new panel can be attached in accordance with that principle, which is offset horizontally blocked the first panel in the first row and predpochtitelno attached along the long edges as long while the upper edge of new and second panels are in contact, and the tongue 10 in the groove 9, as shown in figa-11f. Move the blocking element 61 can, for example, to move vertically through the third panel 1A, which expand to the long edges of the new panel 1' and the second panel 1. The third panel can be pressed to push the edge shift of the blocking element 61 and cause vertical displacement of a portion of the blocking element 61. The blocking element 61 may, for example, to go back to its unlocked position when the pressure is removed. This provides the possibility that the panel can be released by a reverse horizontal offset from the short edges. It is obvious that the vertical displacement based on the principles of communication, wedge and bending, can be used to perform horizontal blocking. This third principle of the invention can also be combined with the first principle. Edges can have the effect of moving the comb and move the blocking element. The blocking element 61 may be on the lower part 10b or on the upper part 10a of the ridge 10 and the locking groove 14 may be in the inner part of the strap 6, or in the upper flange. Thus, the undercut in the locking groove in the upper flange 9a can be formed, for example, by scraping.

Therefore, in compliance and with the third principle of the invention contains the set of essentially identical panels overlap, each of which contains one pair of opposite edges provided with first and second connecting elements made in one piece with the panels and configured to attach adjacent edges vertically and horizontally. At least one of the first or second coupling element comprises a separate locking element is made in one piece with the panel and connected with groove bias in the unlocked position. A separate locking element configured to move horizontally or vertically in one direction only from the inner unlocked position and to an outer locked position for locking two adjacent edges vertically and/or horizontally.

Such an implementation option enhances the setting, because it is not necessary to overcome any force compression to press the blocking element into the groove bias for action vertical or horizontal place.

All embodiments of the invention can be used on long and/or short edges of the panel or in strips, and/or on the panel grooves. The invention does not exclude the combs and on the adjacent edges or more ridges on the same edge next to each other or dropped other. Shows the system block in accordance with the first and second aspect of the invention may be formed so that, for example, can be attached via a pivot, and/or place. System block in accordance with a third aspect of the invention can be locked with the horizontal latching the long edges, whereby, for example, the tongue on the long edge can be pressed to push the edge shift of the ridge during the horizontal latching the long edges. All options for implementation may have a geometry that provides the ability to detach with a reversal up. Panels can have edges that are not perpendicular, and they can have more than 4 edges, such as 5, 6, 8 edges, and even up to 12 edges.

On figa-12d shows a section of the edge shift of the ridge 31. On figa shows a shift of the ridge to its accession in the groove 40 offset. Horizontal ledge 60 in this embodiment has a friction connection 36 and the angle with a longitudinal direction of shifting of crest of approximately 50-60 degrees. On fig.12b shows the initial connection has the effect of moving ridge 31 during the joining of the ridge in the groove 40 offset. Horizontal ledge 60 is bent to a lower angle of, for example, 35-40 degrees. On figs shows the offset shift of the ridge along the connecting edges. This shift puts the effect of moving the comb in the correct position in the longitudinal direction along the short edge and in a predetermined position relative to the long edges of the panel. This offset causes the gland flange 32 in the correct position and eliminates manufacturing tolerances. Blocking high quality requires a shift of the ridge and push the edge 32 were placed with high accuracy, preferably with a tolerance not exceeding 1 mm In fig.12d shown as a shift of the ridge 31 is shifted in the direction of the LD block, perpendicular to the lateral pressure P which is applied parallel to the longitudinal direction of shift of the ridge 31. Horizontal ledge 60 is in this position, the angle of about 70-75 degrees. He bent essentially on a circle C. This is an advantage since the pressure P in the direction of the block can be significantly higher than the power block in the pressed direction PD. This creates a strong vertical locking and force short edge to take a position in the same plane even in the case when the short edges of the panels slightly curved in different directions. On fig.12d shows that push the edge 32 can be bent and flexible. This is an advantage and eliminates manufacturing tolerances, is provided with the location and geometry of the shifting of the ridge and blocking systems. Move the comb may be blocked with pre-tension in the groove 40 at the crest.

On figa-13e illustrates the operation of the shift of the ridge 31 which consists of a very simple component, preferably molded or cast plastic section with a simple and essentially rectangular cross-section. On figa shows the first panel 1 and second panel prior to their accession. On fig.13b shows a cross-section of the short edges 4a of the second panel 1. Figs shows panel attached to the stage. Move the comb is in the groove 40 offset. On fig.13d shown that the new panel 1' (figs not shown) can be moved vertically up and down, and that there is no vertical merger, which prevents the spread up or down the long edges of the new 1' 1 and the first panel. To simplify the description, file presents without the new panel. Attach the third panel 1A to the second panel 1 presses one of the partitions Es1 edges to the edge of the first panel 1", preferably relative to the inner part of the groove 9 under the crest of the long edges, and the other of the sections Es2 edges, in this case the gland flange 32, to the edge of the third panel 1A, preferably relative to the ridge 10 of the long edges. Move the comb 31 is bent in a horizontal plane and in the longitudinal direction. H is b can move in the groove 20 under the crest, as shown in fig.13f. Move the comb 31 is returned to its original position, as shown in figs, if the third panel 1A is cut off, and the pressure on the section Es1 and Es2 edges removed. It provides the ability to disconnect the new panel 1' through the action of a reversal upwards. Blocking with vertical fold and detach with a reversal up is preferably performed along the vertical plane VP with the upper edges of the new and second panels are in contact. Bending or displacement preferably should be more pronounced in section Es1 edge, which is opposite the section Es2, where the applied lateral pressure. This gives a more solid blocking, because of the friction force in the longitudinal direction of the connection can be reduced, and the normal component of the force is directed into the groove under the ridge, may be higher. This means that the bending may begin in section Es2 edges, and it may gradually increase to a push section Es2. The comb can get locked position so that the main part of the middle section will be parallel with the groove under the crest. The main advantage compared with the known technology is that much more pressure during the final stage of the block than during the initial one hundred the AI. This can be used to block edges with strong pre-stretching. In known systems of the block there is the opposite situation, where the pressure ridge is in its peak condition, when the comb is in the inner position. It is of advantage if the lower part of the groove 40 offset formed in a plane which is above the upper part of the blocking element, as shown in fig.13f.

On figa-14b shows that the bending shift ridge 31 can be facilitated, if the effect of moving the comb in the unlocked position horizontally slightly curved in the longitudinal direction.

On figs shows the effect of moving the comb 31, which in this case is also a flexible comb because it is flexible in the longitudinal direction. It has a simple and essentially rectangular cross-section and at least one frictional connection which holds the comb in the groove displacement during transportation and setting. The ridge has a length L and direction W of the width. On fig.14d shows the effect of moving the comb 31, which is slightly curved horizontally in a horizontal plane parallel to the main plane of the panels. This facilitates additional bending and offset. On file shown that the frictional connection can be replaced by maxemum crest, which is slightly curved vertically, perpendicular to the horizontal plane. It is obvious that the combs can be attached in the groove bias without any special frictional connection or curved forms. Enough can be a tight fit. Glue is not excluded. All of these options for implementation may be combined. For example, the comb can be made so that it was slightly curved vertically and horizontally. All these ridges are preferably formed from a plastic material using injection molding or by extrusion, or simply by stamping plastic material in the form of a sheet.

On fig.14f-14h shows another principle of education has the effect of moving ridge. The comb has along its length L middle section S1, which has a smaller width than the portion located closer to the sections Es1, Es2 edges. This facilitates bending. Figd and 14h show bending when applied to relieve lateral pressure P.

On figa-15c shows a variant implementation of shift and bent ridge 31 with sections Es1, Es2 bent edges, which provide the possibility of displacement of the main part of the ridge, and which has a vertical locking element 19 is essentially over the major part of the length of the short edges.

On fig.15d-15e shows that section of the bent edges in accordance with the Phi is .15a-15c and bending in accordance with fig.14b can be combined.

On fig.15f shown that the effect of moving the comb can be shifted by means of a tool, which creates lateral pressure.

On figa-16d shows the joining of the individual ridge or any similar free item. Move the comb 31 is attached in the groove 40 on the edge by means of the pusher, which preferably attaches one edge of the ridge. On fig.16b shown that in addition, you can use the clamping wheel PW to attach a shift of the ridge 31 in the groove 40. On fig.16d shows that you can use the positioning device PD to install the ridge at a desired position relative to one long edge. This can be done combined in a continuous stream.

On file shown as offset or bent ridge 31 can be formed from the billet TB ridge, for example, from extruded section, which was subjected to punching to form and separate the combs from extruded billet TB ridge. The frictional connection can be formed, for example, by stamping or by using heat.

On figa-17j depicted embodiments of flexible and shifting ridges 31 in accordance with the invention. On figa-17b shows the bent ridge 30 with the middle section containing two parts, separated from each other in the direction of the width W. In figs-7e shows the crests where the width W varies along the length L bent ridge 30.

All figa-14h, 15a-15e and 17a-17e are examples of embodiments based on the principle of bending.

On fig.17f - 17g shows the principle of a wedge with a shift of the double crest, with two parts 31a, 31b, containing interacting wedges 70, which is displaced and separated from each other in the direction of the width W while applying lateral pressure P.

On fig.17h-17j shows a section of the double edge of the ridge on which are attached two parts 31a and 31b. On fig.17h shows how this double comb can be made and folded together when it is attached, as shown in Fig. The connection 62, which connects these two parts can bend, extend, shrink or be separated from one of the parts, when put side pressure P.

On figa-18c shows a variant implementation of the shift of the ridge 31 in accordance with the principle of communication, which has several horizontal ledges 60, which during the joining of the ridge to the groove 40 (fig.18b) and offset (figs) are rotated around a Central point. The tabs can be bent, and they may permanently be rotated or, alternatively, to bend so that they can return, at least partially, to the initial unlocked position, when lateral pressure is removed.

On the .18d shown billet TB molded section is essentially rectangular cross-section, containing one or more friction connection 36, as shown in figa.

Options for implementation, as shown in fig.18f-18i, and which is based on the principle of communication, show how a fairly complex form with one or more horizontal ledges containing a frictional connection can be obtained by stamping and/or shaping of the workpiece from the pressed section.

On fig.18h and 18i shows that it is possible to combine the principles of obtaining the horizontal displacement in the groove under the crest with the help of lateral pressure with a crest containing a horizontal ledges, or with a comb, which is bent. Shows the ridge 31 is partially offset by means of horizontal protrusions 60 in accordance with the principle of communication and partly by using portion in the shape of an arc, which is shifted in accordance with the principle of bending.

Known technology as described in connection with figures 1 and 5 may be combined with the variants of the embodiment of the invention. The bent part of the ridge, you can press into the groove offset during the vertical folding, as shown, for example, in figure 5, and after that it can snap back into the groove under the crest. You can then put lateral pressure and you can get the final and more solid blocking in accordance with the principles of the invention. Such combinations also what you can do with flexible locking element, which is blocked horizontally, as shown and described in connection with five-11g.

On figa shows a variant implementation of the principle of pre-stretch, where two pieces of bent ridge 30 are attached to each other under pre-tension by means of a hook 63. On fig.19b shows the ridge 31, when the pre-tension was removed by means of a hook 63.

On figs-19e shows that this hook may be released by vertical pressure caused by the edge of the folding panel 1', and the part of the ridge 30 is deflected into the groove under the crest.

On figa-20b shows a variant implementation of the principle of pre-stretch, where the inner part of the ridge 30 is flexible and encourages external hard part in the groove under the crest, when the hook 63 removes the preliminary stretching. The flexibility obtained through elastic cavity 72.

On figs shown formed by molding flexible comb 30, where the offset is based on the principle of pre-stressing and where, during the vertical folding several hooks 63 gradually removed prior stretching. Part of the crest 31 will gradually be displaced in the groove under the crest. Obviously, this flexible comb can be used to block flooring boards without hooks 63 and Principe is double-acting, where part of the ridge gradually shifted into the groove offset and back again in the groove under the crest in accordance with known principles associated with vertical folding and described with reference to Fig.1-4. The internal groove with its essentially hard part 73 may be permanently attached in the groove offset by a strong friction or pre-stretch, or alternatively, it can be glued to the groove. The crest may have several sections 72 elastic cavities. They can be attached on one or both sides with hard parts 73 - one in the inner part of the groove of the shift and one in the outer part which is locked in the groove under the crest.

It is also clear that flexible combs can be made, for example, in accordance with the variants of the implementation 17b, 19b and 20b in such a way that they can be compressed, and so that they can be used to block flooring boards in accordance with the principles described with reference to figures 1 to 4, where part of the bent ridge is bent in the longitudinal direction during the vertical folding. The ridge 30 can, as shown in fig.20b, have an inner flexible part 72 and the hard outer part 73, which is locked in the groove under the crest, when the bent portion 72 is compressed during vertical kladiva the Oia in position, as shown in figa. Of course, the ridge 30 can have its length several of these bent sections 72, which are curved and compressed in the longitudinal direction of the ridge. This principle is shown in figa, 20b.

On figa and shows a variant implementation in accordance with the principle of the wedge portion 70 of the wedge is separated from the shift of the ridge during the displacement groove 40. On fig.21b shows the ridge 31, where the movement of the several parts separated.

On figs shown formed by injection molding comb 31 with multiple horizontal protrusions 60 in accordance with the principle of communication, where the thickness and width of the ridge vary in length.

On fig.21d shows the ridge 30 with multiple parts in the form of an arc, which can be moved in accordance with the principle of bending.

On figa and 22b are shown as the last row located close to the wall 71 may be blocked, if the comb 30, for example made in accordance with the principle of bending. The outer part of the ridge 30 is shifted in the direction of a simple tool. This method can also be used for the first series. Alternatively, the groove offset can be inserted tool in the form of a needle to move the comb. On one edge you can use friction or a similar compound to block the first row in the same way as all other panel is I. In most embodiments in accordance with the principles of the wedge and communication the offset of the first row is performed in the same way as in all other rows.

On figa-23c shows a variant implementation in accordance with the principle of the wedge, which consists of two parts 31a and 31b, are stacked together and attached to the same component with one or more wedge-shaped hooks 77. Offset, manufacturing tolerances and pressure forces can be controlled very accurately by means of curved and/or bent pins 70a, 70b and the blocking parts 78a, 78b, which are blocked along the connection and which interact with each other to facilitate a controlled shift in the groove under the crest. Complex, advanced and effective from the point of view of characteristic features can be performed preferably by injection molding. In the preferred embodiment, these two parts are made in the same mold.

Shows the options for implementation are only examples. Using combinations of the shown embodiments and generally known principles can be made "unlimited" number of alternatives.

On figa-24d shows the blocking Board flooring, which in this case is the wood floor, the floor and the offset is performed in accordance with the principle of bending. The ridge 30 in this embodiment is fixed on the Board of the flooring so that it extends slightly beyond the crest (grooves) 9 long edges. When bent comb 30 is in contact with the inner part of the groove 10 under the crest, he moves along the connection, as shown in fig.24b. The third panel 1A is attached with a reversal, and its crest 10 presses on a pressure edge 32 bent ridge 30. On fig.24d shows how the ridge 31 is compressed with one of its sections Es1 edges in contact with the inner part of the groove 9 of the long edges of the first panel 1", and the other section Es2 edges in contact with the upper part of the ridge 10 of the third panel 1A. The principle of bending provides the ability to set the overlap in both directions - with a part of the crest of the long edges of the strip or strap long edge at the crest. You can mention that you can get a compression of approximately 0.5 mm, the bending of the ridge approximately 2 mm, Even with manufacturing tolerances that make up approximately 0.1 mm for flexible ridge 30 and for mechanical processing Board 1 deck, ridge 10 and the groove 9, it is possible to obtain the blocking of high quality, mainly due to the compression of the fibers that form the arc of transformations is : in a straight line, when the pressure and displacement along connections increase.

On figa shows a new version of the implementation of the bent ridge, which can be used to block flooring boards with vertical folding in accordance with a known principle, where, during the vertical folding comb is shifted to the inside edge. The offset is called elastic cavities 72, which can shrink and curl. On figa shows an external lock position, bent ridge 30, and fig.25b - internal concise and unlocked position. In this embodiment, the ridge has a rigid outer portion 73, which is locked in the groove under the crest, when the bent portion 72 jumps back to its original position. Of course, bent ridge 30 may have several such sections 72 elastic cavities along its length, which are bent and compressed in the longitudinal direction of the ridge.

On figa shows an implementation option, which can be used for setting to a predetermined position and fix the shifting of the ridge to prevent the displacement of the comb along the connection, when put side pressure. This implementation provides the possibility that even the panel in the first row can be locked down by bending the comb. Move the comb imambekov hook 79, which is blocked, for example, relative to the inner part of the groove 9 of the long edges. Side hook through the protruding part 80 is attached to section Es1 edge of the tongue opposite the push edge 32. This side hook 79 is also used for the location of the ridge 30 and the push edge 32 in the correct position relative to the long edges. On fig.26b shown bending, when put side pressure P. the Side hooks and positioning elements can be applied on both long edges as alternatives mentioned above frictional connection. Side hook, for example, can be used in the locking groove long edges.

On figs shows an implementation option with a friction connection 36, which prevent displacement along the edge. Part of the crest can also be glued to the edge. Push the edge has a locking tab 81, which continues groove long edges. This ledge can be used, for example, in a wooden slab with a core of thin plates to bridge the space between the thin plates and to ensure that part of the ridge is always to press the gland flange 32.
