The invention, in General relates to floor panels that could be installed with mechanical locking systems. The invention also relates to partially bend the ridge for building panels with such mechanical locking system.

Specifically, but not as limitation, the invention relates to comb the floor panels and floor panels, mechanically joined in preferably a floating floor.

However, the invention is applicable in General to the construction of the panels. More specifically, the invention relates to the type of mechanically connecting the castle of systems containing flexible or partially flexible comb and/or a shift of the ridge, to facilitate the installation of building panels.

The floor panel of this type is presented in WO2006/043893, revealing a floor panel with a locking system that contains a locking element cooperating with a locking groove for horizontal connections in the castle, and flexible comb, interacting with groove ridge for connection to the castle in the vertical direction. Flexible comb is bent in the horizontal plane during the joining of the floor panel and makes it possible to install panels vertical insertion or only vertical movement. Vertical insertion" means the combination of three panels, where the first and second panels nahodatsa is in the United state and one swivel action connects two perpendicular edges of the new third panel simultaneously to the first and second panels. This connection takes place, for example, when the long side of the first panel in the first row already soedineniya with the long side of the second panel in the second row. The third panel, which in this text referred to as the "put"panel, then connect by turning to the long side of the first panel in the first row. This specific type rotary action, which also connects the short side of the new third panel and the second panel in the second row, referred to as "vertical insertion". Also is it possible the connection of two panels by lowering the entire panel only, essentially vertical movement to another pane, where, essentially, turning the edge of the panel is not involved. This connection of two panels referred to as "vertical connection to the castle"

A similar floor panel is additionally described in WO2003/016654, which discloses locking system that contains the crest c of the flexible tongue. The ridge extends and is bent essentially in the vertical direction and the top of the tongue interacts with the groove of the crest vertical coupling in the castle. The flexible tongue is directed upwards and is put on the panel. The main disadvantage of this option is that the flexible tongue should move inside sharp edge of the panel as shown in figa.

In the following text in the apparent surface of the installed floor panel is called "front side", and the opposite side panels of the floor, turned to the black floor, called "rear side". The edge between the front and rear sides is called "the edge of the junction. "Horizontal plane" means a plane that is ongoing in parallel to the outer part of the surface layer. Located directly next to the upper parts of two adjacent edges of the junction of two coupled floor panels together form a "vertical plane"perpendicular to the horizontal plane.

"Joint" or "locking system" means acting together connecting means connecting the floor panel vertically and/or horizontally. "Mechanical locking system" means that the connection can be made without glue. Mechanical locking systems can in many cases also be combined with bonding. "Integrated" means made as a single piece with the panel or connected to the panel at the factory.

"Flexible comb" means a single comb, aiming along the length around the edges of the joint and forming part of the vertical locking systems and which can be displaced horizontally in the process of connection to the castle. Ridge, for example, can be bend or be flexible or elastic part such that it can be bent along its length and get back to its original position.

p> "Turn" means a compound that is a turning movement, which is the angle between the two connectable or releasable parts. When turn refers to the connection of two panels of the floor, is the angular displacement, while the top edges of the joint, at least partially, are in contact with each other, in the process, at least part of the movement.

The present invention is the creation of a set of floor panels or floating flooring and comb the floor panel, which creates new options for implementation according to various aspects of the offering of benefits. Application of the invention are floor panels of any shape and from any material, such as laminate flooring, HDF/HDF, veneer or stone.

According to the first objective of the invention results from the set of floor panels containing mechanical locking system on two adjacent edges of the first and second panels, while the locking system is configured to connect the first panel with the second panel in the horizontal and vertical planes. Locking system designed to facilitate adjustment to a shift of the ridge to connect to the castle in the vertical plane. The crest is a shift in the groove of the shift in the edge of one of the panels on the and made interoperable c comb grooves in the other of the said floor panel. The first long edge of the crest contains at least two bendable tabs, ongoing, essentially in the horizontal plane and bending in the horizontal plane. The second long edge of the ridge, which in the United state continues outside of the groove offset is essentially a straight outer edge, essentially, the entire length of the ridge.

Since the floor panel according to the first objective of the invention is equipped with a shift of a crest with bendable tabs and, essentially, a straight outer edge, it offers a number of advantages. The first advantage is that the floor panel is connected to the castle in the vertical direction along essentially the entire length of the ridge. The second advantage is that it is possible casting of the ridges of one item, for example, plastics material and, if necessary, cut them into shorter combs, all essentially have the same properties. One tool castings can be used for production of flexible ridges for panels of different width. Specially can be obtained, the offset resistance and durability mating in castle per unit length. The third advantage is that the resistance to displacement due to bending of the projections is essentially the same along the entire ridge. More tabs creates a more constant is soprotivlenie offset along the edge of the ridge. If the panels is determined by vertical insertion, preferably constant resistance to displacement along the edge of the ridge. Also provide a large angle between the input panel and the second panel when putting the panel initially in contact with the ridge of the second panel. The tabs are designed with the possibility of bias, but also to prevent deflection of the ridge.

The floor panel that is known from WO2006/043893, as mentioned above, revealing a flexible comb in the shape of an arc, bend in the direction of the length. The disadvantage of this crest in the shape of an arc is that because this form there is no connection to the castle at the end of the ridge. Shows one variant of implementation, creating a connection to the castle along the entire length (fig.7f), but this comb consists of two connected parts (38, 39). Also is important that the ridge is easily elastically moves back after the offset into the groove during installation. Therefore, preferably, if part of the crest of the interacting c adjacent panel, is relatively stable and is equipped with the sliding faces of the c area, sufficient to prevent sticking of the ridge before reaching the end position for vertical mating in the castle. The sliding surface on the top of the tongue or projection therefore is not a viable solution.

Preferably, the protrusions ridge moulded into the shape of an arc, providing essentially constant shoulder torque during installation of the panels bending of the tabs.

Preferably, the comb contains neckline with each protrusion, resulting in the exclusion of deformation and cracking of the ledge, if the comb is shifted too far and applied too much force.

Preferably, the length of the ridge is more than 90% of the width WS of the front side panels; in other preferred embodiments, the implementation of the crest length is in the range from 75% of the width WS of the front side panels, essentially, to one width of the front side of the panel.

According to the second task in the invention results from the crest to the building panel, the said ridge has an elongated shape and made of molded plastic. The crest contains at least two protrusions on the first long edge of the ridge. The protrusions are bendable in a plane parallel to the upper surface of the ridge, and continued essentially in parallel planes. In addition, the ridge has a second long edge, which is essentially direct, essentially along the entire length of the ridge.

The first advantage is that the ridge creates a connection to the castle in the vertical direction along the entire length of the ridge. The second advantage is that it is possible casting comb in one piece from plastic and, if necessary, cut them into shorter combs, all essentially have the same properties. In particular, the offset resistance and the strength of the connection in the castle per unit length can be the same. The third advantage is that the resistance to displacement due to bending of the projections is essentially the same along the entire ridge. More tabs creates a more constant resistance to displacement along the edge of the ridge. Even the relatively hard materials, such as reinforced plastic, metals, such as aluminum, and wood, can be flexible with the projections according to the projections of the invention. If the panels is determined by vertical insertion, such as the installation method, explained below (see figure 5), preferably constant resistance offset.

According to the third task of the invention results from the set of floor panels containing mechanical locking system on two adjacent edges of the first and second panels, while the locking system is configured to connect the first panel with the second panel in the horizontal and vertical planes. The castle system is designed for easy installation with offset ridge for mating to the castle in the vertical plane. The crest is a shift in the groove of the shift in the edge of one of the floor panels and is made with the possibility of the awn interaction c groove ridge in the second of the aforementioned floor panels. At least one long edge of the crest, which in the United state continues beyond the grooves offset, contains at least two bendable tabs, ongoing, essentially in the horizontal plane and bending in the horizontal plane. This option with shift and bend the tabs on the outer edge offers several advantages. The entire comb may also be shifting. The first advantage is that only a portion of the tongue to be pressed into the groove bias in the process of investing, this should reduce the force of friction to overcome in the process of nesting. The tabs in one embodiment, are a bit more subtle than the body of the comb. A small backlash from about 0.01 to about 0.10 mm may, for example, be formed between at least part of the lip and groove offset, and this gap can essentially eliminate the friction in the process of displacement even when the groove due to tolerances in the manufacture of slightly smaller corps crest. The second advantage is that the tabs can sprinit independently from each other and is more reliable connection to the castle, even in cases where the friction force changes due to tolerances in the manufacture of the groove offset and/or grooves of the comb.

According to the fourth objective of the invention with the given locking system for connection to the castle floor panel, containing mechanical locking system on two adjacent edges of the first and second panels, with mechanical locking system that contains the first connecting device for connection to the castle in the horizontal direction (D2) perpendicular to the adjacent edges, and a second connection unit that contains for easy installation single comb, preferably made of a material separate from the material of the inner layer panel, for connection to the castle in the vertical direction (D1). Part of the ridge is flexible and bendable in the horizontal and/or vertical plane. Locking system is configured to connect the first panel to the second panel by turning, snap, vertical insertion and vertical coupling in the castle. This locking system offers the advantage that the panels can be connected to the castle in several ways and this makes for easy installation.

According to the fifth task, the invention provides a method of installation for the connection of the panels, preferably a floor panel. Panels contain a short region c mechanical locking system for vertical connection to the castle with a separate comb containing flexible portion, and a horizontal connection with a locking rail containing the locking element, and the long side of the c mechanical locks the th system, containing a ridge, groove, lock rail and a locking groove for vertical and horizontal connections in the lock by turning. The method comprises the following steps:

a) install the second row of panels, connect the short side panels c vertical connection in the lock or snap, while the flexible part of the ridge shifts and

b) connect the second row is already installed and adjacent the first row by turning.

As shown in Figure 5-18, the invention relates to a set of floor panels with a shift of the ridge, a shift of the comb panels, locking system for floor panels and method of installation of the floor panel.

Panel 1,1' floor existing state of the art, equipped with a mechanical locking system and a shift of the ridge, is described with reference to Figa-1d.

On Figa schematically shows the cross section of the junction between the edge 4a of the junction of the short side of the panel 1 and the opposite edge 4b of the junction of the short side of the second panel 1'.

The front side panels, essentially, are mounted in a common horizontal plane HP, and the upper part 21, 41 of the edges 4a, 4b of the joints against each other in the vertical plane VP. Mechanical locking system provides connectivity to the castle of the panels to each other in the vertical direction D1, and in the horizontal direction D2.

To ensure the joining of two edges of the joint in directions D1 and D2 of the edge of the floor panel are well known castle rail 6 with a locking element 8, hereinafter referred to in this document referred to as "stacked bar", which interacts with a locking groove 4 in another region of the junction, then inthis document called "put"panel, and provides horizontal connection into the lock.

Mechanical locking system existing prior art contains a separate flexible comb 30, fixed in the groove 40 offset formed in one edge of the joint. Flexible ridge 30 has a section P1 of the grooves located in the groove 40 offset, and the protruding section P2, protruding beyond the grooves 40 offset. The protruding section P2 flexible ridge 30 at one edge of the interface communicates with the groove 20 of the ridge formed at the other side of the junction.

Flexible ridge 30 has a protruding portion P2 with a rounded outer part 31 and a sliding surface 32, which in this embodiment is designed as a bevel. He has an upper surface 33 and the lower surface 35 of the offset of the ridge and the inner part 34.

The groove 40 offset has a top edge 42 and bottom edge 46 of the aperture, which in this embodiment are rounded surface 44 of the bottom and top surface 43 and the bottom surface 45 offset grooves, preferably essentially parallel to the horizontal plane HP.

The groove 20 of the ridge has a locking surface 22 of the locking ridge interacting with flexible comb 30 and the locking edges in the vertical direction D1. Put the panel 1' has a vertical locking surface 24, which is located closer to the rear side 62, che the groove 20 of the ridge. Vertical locking surface 24 cooperates with the rail 6 and connects to the castle of edges in the other vertical direction. Put the panel has, in this embodiment, the sliding surface 23, interacting in the process of connecting the castle with a sliding surface 32 of the ridge.

On Figa shows the cross section A-A panel according fig.3b in the top view. Flexible ridge 30 has a length L along the edge of the junction, the width W parallel to the horizontal plane and perpendicular to the length L and thickness T in the vertical direction D1. The greatest amount of area P1 and the most protruding part P2 is the full width TW. Flexible ridge is also in this embodiment, the middle section of the MS and two marginal sections ES adjacent to the middle section. The size of the protruding part P2 and the size of the P1 section of the groove is changed in this embodiment, along the length L and the ridge separated from the two corner sections 9a and 9b. Flexible ridge 30 has on one of the edge sections of the friction connection 36, which may be in the form of, for example, local small vertical ledge. This frictional connection holds the flexible ridge in the groove 40 offset in the installation process or in the process of production, packaging and transportation, if flexible comb built into the floor panel at the factory.

On Figa the 2b shows the position of the flexible comb 30 after the first offset to the bottom 44 of the groove 40 offset. The offset is determined, essentially, by bending the flexible comb 30 along the length direction L parallel to the width W. This characteristic is significant in this sample current level of technology.

Put the panel may detach needle-like instrument is inserted from the side of the corner section 9b in the groove, and push the flexible comb back into the groove 40 offset. Put the panel can then be turned upwards, while the laid panel remains on the black floor. Of course, the panels can also be disconnected in a traditional way.

On Figa and 4b shows one variant of implementation of vertical nesting. The first panel 1" in the first row are connected with the second panel 1 in the second row. The new panel 1' is connected with its long side 5a with the long side 5b of the first panel by turning. This pivoting action also connect the short side 4b of the new panel with the short side 4a of the second panel. Put the panel 1' is connected to the castle with the laid panel 1 through the combined vertical and rotary movement along the vertical plane VP. The protruding part P2 has a rounded and/or angled invest part of the P2', which is in the process of inserting interacts with a sliding surface 23 invested panel 1'. The combined effect of investing part 2' and the sliding surface 32 of the ridge, in the process of inserting interact with a sliding surface 23 invested panel 1', facilitates the first offset flexible ridge 30. The essential feature of this option is to position the speaker area P2 is separated from the corner sections 9a and 9b. The spacing is at least 10% of the length of edges, in this case, the visible short side 4a.

On Figa-5c shows a variant implementation of the set of floor panels with a shift of a comb according to the invention and the preferred method of installation. In this embodiment, the length of the ridge is more than 90% of the width WS of the front side of the panel, in other preferred embodiments, the implementation of the crest length is preferably from 75% to, essentially, of a length equal to the width WS of the front side. Preferably, the length of the ridge is approximately the full width of panel minus the width of the locking systems adjacent edges of the panel. A small bevel can be performed on the ends of the outer edge, but a direct part of the ridge on the outer edge preferably has a length essentially equal to the length of the ridge or preferably more than 90% of the length. The new panel 1' is set at an angle to the top edges are in contact with the first panel 1" in the first row. The new panel 1', then moved to the second panel 1, while the edges will not, by beings who, in contact and the flexible part of the ridge 15 is pressed into the groove 40 offset, as can be seen in fig.5b. The new panel 1' then goes down to the second panel 1. Since the offset of the new panel 1' presses only section of the flexible edge of the ridge 15 in the groove 40 offset, vertical insertion should be possible to do with less resistance. The installation can be performed with a shift of a comb having a straight outer edge. When set the bar with the famous crest 30 arc shape (see Fig.2-4), the entire tongue pressed into the groove bias. When comparing the well-known crest of the arcuate shape with a comb according to the invention requires less effort for the crest with the same stiffness characteristic of the spring per unit length of crest. Therefore, it is possible, using the principles of the invention, to use a comb with a higher stiffness characteristic of the spring per unit length and a higher return force of the spring, resulting in a more reliable final position of the crest. With this installation method beveled sliding surface investing panel is not needed or may be less, which is an advantage for thin panels. If the comb is not long enough, the above method of installation does not work, and the beveled sliding surface PA is eating is necessary.

On Figs shown that the comb can be put on the panel.

The preferred production method according to the invention is injection molding. This production method can produce a wide variety of products with complex three-dimensional shape at a low cost, and flexible combs 15 can easily connect to each other to form blanks 50 ridge. The comb also can be made of extruded or subjected machined plastic or metal sections, which additionally is shaped, for example by stamping, to form a flexible comb according to the invention. The disadvantage of extrusion, in addition to additional stages of production, is the difficulty of reinforcement ridge, for example, fiber.

As you can see, comparing shown in figure 5, and 4, the angle between the new panel l" and the second panel 1 is great for panels with flanges according to a variant embodiment of the invention, when the new panel is initially in contact with the end of the ridge 15 and starts the offset of the ridge in the groove 40 offset. If the angle is greater, this is an advantage since a larger angle means a more comfortable working position, in which it is easier to apply more pressure, stalkivalsia the ridge in the groove offset.

Any type of polymeric materials can use in order to use, such as polyamide (nylon), Polyoxymethylene, polycarbonate, polypropylene, polyethylene terephthalate, polyethylene, or similar, with the properties described above, in various embodiments, implementation. These plastic materials using injection molding can be reinforced, for example, glass fiber, aramid fiber, carbon fiber or talc or chalk. The preferred material is glass fibre reinforced, preferably increased length, polypropylene or Polyoxymethylene.

On figa-e are shown embodiments of the ridge 15 according to the invention. They are all made with the possibility of inserting groove in the floor panel in a manner similar to that described above for the ridge and panels existing state of the art with reference to Fig.1-4. All methods of injection molding, insert, and tools for disassembly as described in WO2006/043893 and partially above in the description and figures 1 to 4 are applicable in the invention.

On figa shows an implementation option c first long edge L1 and the second long edge L2. The first long edge has projections continued in the plane parallel to the top side 64 of the ridge 15 and at an angle relative to the longitudinal direction of the ridge.

On figa-b shows an implementation option, a top view and a side view, with the first long edge L1 and the second long edge L2. long edge has projections 61, continuing in the plane parallel to the upper side, the upper surface 61 of the offset and the rear side, the lower surface of the displacement of the comb at an angle relative to the longitudinal direction of the ridge. The protrusions preferably given a curved shape, in a particularly preferred embodiment, the ridge is equipped with a notch 62 at each protrusion 61. The cutout is preferably adapted to the size and shape of the ledge.

The protrusions preferably equipped with a frictional connection 63, most preferably near the top of the ledge, which can be given, for example, the form of local small vertical ledge. This frictional connection holds the flexible ridge in the groove 40 offset in the installation process or in the process of production, packaging and transportation, if the effect of moving the comb is embedded in the floor panel at the factory.

On fig.6d shows the ridge 15 in cross section B-B on figs and installed in the desired position in the groove 40 offset panel 1. The upper and lower surfaces of the displacement of the comb made with the possibility of interaction of the upper surface 43 with the bottom surface 45 of the groove offset. The panel contains a locking rail 6, the locking element 8 for horizontal connections in the castle. The panel 1 has a capability of the second panel 1' by the way, the same panel 1 current level of technology, shown in figa-1d. The upper surface (64) offset and/or the lower surface of the offset (65) crest fitted in one preferred embodiment, beveled edges, presents sliding surfaces (32, 31) and an inclined surface (66) of the connections in the lock, respectively. Inclined surface connection to the castle interacts preferably c inclined surface 22 of the connecting ridge to the castle in the groove (20) of the ridge.

In variants of the implementation according to the shown fig.6d and 6e groove 40 offset is formed as a unit with the inner layer of the panel, but there may be other alternatives. Groove bias can be performed in a separate material, such as HDF/HDF, which is connected with the inner layer of the parquet floor. Groove bias can be made of plastic or metal sections in the form of channels connected to the panel, for example, locking connection, adhesive, or friction. These alternatives can be used to reduce friction and facilitate horizontal offset of the ridge in the groove bias. Groove bias may also be processed by a material that reduces friction. These principles can also be applied to the grooves of the comb.

On file shown that the ridge 15 may also be inserted into the groove 40 offset panel for mating to the castle in the horizontal plane. Graebe the is shifted in the vertical plane in the process of connecting panels. Panels of this type are connected by moving in the horizontal plane, i.e. horizontal place".

To facilitate installation, it is preferable if the stiffness characteristic of the spring protruding part is as linear as possible. The result of linear stiffness characteristics of the spring is good and smooth movement of the connection without unexpected sharp increase in the resistance to the offset. According to one variant of implementation of it with the tab arcuate shape. On fig.8b shown that the result of the arcuate protrusion shape is essentially constant shoulder torque force during the whole process of joining two panels have at the top of the ledge, and essentially linear stiffness characteristic of the spring. On figa shown that the direct projection is that the shoulder torque is changed during the process; the force is distributed over the greater part of the length of the protrusion, resulting in increased stiffness of the spring characteristic in the time process. F is the force displacement, and L is the distance of the offset.

Preferably, the cutout when the protrusion has an advantage in that the tab is not destroyed if too much force is applied, or if the comb is shifted too far. The tab is pushed in you is ez and the broken ledge excluded.

On figa-b shows two enlarged version of the implementation part of the crest in the top view and isometric. Shows the sprue 71 that is cut off before inserting into the groove offset.

It is preferable that the length PL of the projection more full-width TW of the ridge. Full width is the width W of the comb plus the distance from the crest to the top of the ledge perpendicular to the direction of length of the ridge. In the most preferred embodiment, the PL is greater than 2*TW. It is also preferable that the cutout is wider near the top of the ledge, than near the bottom of the cutout, as shown in figa.

Preferably, the power offset of the comb 1 mm per 100 mm length of the ridge is in the range from about 20 to about 30 N.

Preferably, the length PL of the projection is in the range from about 10 mm to about 20 mm, the width W of the ridge is in the range from about 3 mm to about 6 mm and the total width TW of the ridge is in the range from about 5 mm to about 11 mm, the length of the BP part of the body between the two protrusions, that is, the distance from the root of one ledge to the top of the adjacent protrusion is in the range from about 3 mm to about 10 mm as a non-limiting example, the width of the floor panel 200 mm, which includes the width of the locking systems on the adjacent edges c length of crest of about 180 mm, with 9 tabs, the length of the projection is about 15 mm, length BP part of the body is about 5 mm, W the width W of the ridge is about 5 mm and the total width TW is about 8 mm

Combs according to variants of the invention may all be cast in one piece. Additionally, you can cut molded ridges on the shorter parts that all have the same properties per unit length provided that the number of protrusions is not too small. Another method of manufacture is extrusion, combined with cutting out or cutting grooves and ridges of the ridge.

On figa-9d shows the locking system, providing a vertical insertion and vertical coupling in the lock according to the basic principles of the invention. To facilitate the connection lock lock system contains a reducing friction material(71, 71', 71"), such as wax, oil, or similar chemicals on the edge of the panel 1' and/or the locking element 8 and/or the locking groove 14. Preferably, all flexible ridges, shown in this embodiment, the practical application, supplied with decreasing friction material, such as wax or oil.

On figa-10d shows that the locking system, providing a vertical insertion can also be designed with the option of connection to the castle horizontal snap. In this embodiment, the snap largely facilitated by the flexible comb (15). Locking system can be designed with the option of connection to the castle with a lot of the output horizontal offset or c by combining the horizontal and vertical offset, as shown in figa-d. The outer part of the ridge 15 and the edge of the panel 1 can be designed with chamfers and/or rounded parts, facilitating the snap.

On figa 11d shows that the snap can also join c flexible rail (6), which is in the process of latching bent down to the black floor.

On figa-12d shows that the locking system can also be designed to provide connectivity to the castle by turning. On Fig.12d it is shown that the locking system can also be unlocked by turning. Wax or decreasing the friction materials of other types can be applied to the grooves offsets, ridges or grooves in the locking system, in particular on the surface, which in the process of connection to the castle are in contact c flexible comb. This lowers the friction material should improve the functioning of the connections in the lock and disconnect from the castle all locking systems, for example, shown in fig.2b, 13c-d, 14a-c, 15a-b and 17a-e, where part of the ridge is flexible.

Locking system, which can connect to the castle with a vertical insertion, vertical connection to the castle, turn and snap, you can have the crests of many different types, made of material that is separate from the inner layer panel, ridges, connected to the panel edge and ridges, with m is Nisha least one flexible portion. Examples of embodiments of the castle, ridges, providing the possibility of such compounds in the lock shown in fig.2b, 13c-d, 14a-c, 15a-b and 17a-e. Can be used all types of flexible ridges, for example, having locking tabs bent in the direction along the length of having flexible protrusions inside or outside of the grooves, and the like. According to the invention created locking system with separate comb having at least one flexible portion, and this locking system has a means of connection to the castle, representing the possibility of vertical and horizontal mating in lock with vertical insertion, vertical connection locking snap c flexible rake or without and with rotation. It can also uncouple turn. This locking system should offer a number of advantages during installation of the floor panels. Of course, the locking system can be designed such that one or more functions connection to the castle, mentioned above, could not be tolerated. For example, the locking element with a locking surface essentially perpendicular to the horizontal plane, should prevent disassembly by turning the dial up. This locking system must have high strength in the horizontal direction.

Vertical in ladymania in most cases is the most convenient way to install. However, figa and 13b shows an alternative installation method. The short side panels in the first row R1 are connected. The short side panels in the second row R2 are connected to each other vertical suedeniam in the castle or horizontal snap where the part of the individual comb containing the flexible portion is displaced in the process of connection to the castle. This method of connection is very simple, because the panel to lay flat on the subfloor short edges to each other and connect. They do not need to rotate or snap together with the punch. Two adjacent rows R1 and R2, then connect the bend.

The method includes the installation of floor panels containing short edge c mechanical locking system for connection to the castle adjacent short edges vertically by means of a separate comb containing flexible portion, and horizontally, a locking rail containing the locking element, and the long sides by means of mechanical locking systems containing a ridge, groove, lock rail and a locking groove that provides vertical and horizontal connections in the lock by turning:

a) install the second row R2 panels, connecting the short sides of the panels c vertical connection to the castle or horizontal snap, and the bending is the art of the ridge is displaced, and

b) connect the turn of the second row R2 is installed and attached near R2.

On figs-13 shows that the individual materials 72-73 can be used to improve the strength and function to make a connection to the castle. These individual materials, which can be connected as a section of the region, for example, laminate or wooden floor panels, and they can preferably contain hard wood, plywood, plastics, MDF/HDF, MDF/MDF and the like. The individual materials can be attached to one or both edges. They can form part of the groove offset, as shown in figs, part of the grooves 20 of the comb, as shown in fig.13d, or even at least part of the locking rail 6 and the locking groove 14, as shown in figa. The individual materials can be used in all locking systems c separate and partially flexible ridges. These principles can be used, for example, locking systems, shown in figa-17e.

On figa and 14b shows that the protrusions 61 may be located inside or outside of the groove 40 offset. Flexible tabs located outside the grooves offset, can be designed with the ability to interact with the groove of the crest vertical panels in the lock.

On figa shows a variant implementation of the flexible ridge 15 with the projections 61 are partially outside of the groove of the MCA is to be placed and c the inner part of the arc shape.

On figs shown that one segment (E1) short edge of the flexible ridge (15)located in the direction identical with the direction of the tabs should be bent outward (provided that the frictional connection does not prevent such bending), if the force F presses on the ridge, when he is in the groove offset with the projections on the inside of the groove. Therefore, it is preferable that in this embodiment, the tabs should be directed to the part of the panel, where the insertion, as shown in figa. Such an implementation option offers the advantage that the flexible comb POPs up from the latch during the end part of the insertion. It is preferable that the flexible comb has at least one rounded or beveled end section (70). Such a plot can be embedded in a molded ridge. It can also be cut or be cut extruded ridge. In this embodiment, there are protrusions 61A and 61b on the parts of the edge of the ridge, and they proceed in opposite directions from each other. The comb also has two sections E1 and E2 short edges, are made such that they do not continue outside of the groove offset as much as the middle part of the ridge. Such an implementation option should facilitate the installation. The shape of projections and sections of the short edges can be used separately or about jedidanno.

On fig.15b shows an implementation option c flexible ridges 15, 15' on each of two opposite edges of the same panel. This is useful in advanced settings. All options for the implementation of certain of the ridges shown in this practical application, can be used.

On figa-16e illustrates embodiments of a flexible ridge 15 with the projections. On figa shows the projections 61 with beveled or rounded top (71). On fig.16b shows the tabs in the depressed position when they are pressed into the grooves 40 offset. On figs shown rounded 72 on the outside of the tabs for easy installation c vertical insertion from both long edges.

On fig.16d and 16e illustrates embodiments of a c double lugs 16, 16' inside and outside grooves 40 offset. All variants of the implementation can be combined. For example, a comb with a double projections, shown in fig.16d and 16e may have a rounded outer part 72, as figs.

On fig.16h and 16a-b shows that the flexible comb 15 may have a body 15a, a little thicker than the part 61a of the protrusion 61, shift into the groove 40 offset in the connection process to the castle. The gap between the groove offset and the guide reduces friction and facilitates reliable displacement of the protrusion 61. It is preferable that the protrusions and the flexible parts are such that part of the ridge that connects Zamok the grooves of the comb, transfer the force of the pressure in the connection to the castle. An example is a crest containing a flexible part, which after 100 hours of compression corresponding to compression during vertical insertion, can spring in position, comprising at least 90% of the original position.

On fig.16f and 16g illustrates embodiments of the ridge, symmetrical in the vertical plane, perpendicular to the edge of the floor panel. These combs have properties that are the same for investments in both directions. The crest on Figg c tabs, extended out on both ends of the ridge, also has the advantage of bearing on the outside the remote edge of the ridge. In another preferred embodiment, the crest with the projections in one direction only, the ridge is symmetric in the horizontal plane, which gives the advantage that you can flip the ridge top down, resulting in the same properties for both directions of nesting.

Locking surface of the locking element 8 on the castle rail 6 can be performed with different angles, chamfers and radius. Locking surface of the locking element 8 can, for example, to go inside to the top edge of the panel, as shown in Fig. The vertical connection to the castle in this embodiment, consist of a flexible gr is bne 15 and the locking element 8 on the castle rail 6.

On figa shows a flexible comb 15 c flexible tongue 75, continuing up. Flexible ridge connects to the panel 1.

On fig.17b shows a flexible comb 15 c flexible tongue 75, continuing down. Flexible ridge connects with the edge, with locking rail 6, continuing from the edge. It is an implementation option is to improve the locking system shown in figa, because the flexible tongue is not offset the sharp edge of the panel. The panel can be performed with a sliding surface 23, to facilitate the displacement of the locking latch 75. Locking tongue can be designed with pre-tensioned, clamped put the cover down, the position connections in the castle. Comb c flexible tongue 75 may be combined with projections made an arc shape according to the basic principles of the invention.

On figs shown that the flexible tongue 75 may be placed inside the groove bias. It can be directed up or down and separate the comb may be of flexible reeds inside and/or outside of the groove offset.

On fig.17d shows an implementation option c two shifting ridges 15, 15' above and below each other. On file shown that flexible comb can connect to the castle on the part of the castle slats 6. All the combs shown in this embodiment, the practical application can be used in such lock is o systems.

Flexible comb c protrusions can be used to connect to the castle very thin floor panels, for example about 6 mm, and even more subtle. Even c vertical thickness of the flexible comb about 1 mm you can get strong vertical connection to the castle. The tabs can be extremely small. They may, for example, just go to 1 mm or even less in the grooves of the comb and 10 mm length comb can be more than 1 tab.
