Floor covering and laying method

FIELD: construction.

SUBSTANCE: floor covering consists of many separate panels laid so that they are connected to each other. On end and longitudinal sides of panels there are fixing planks which, in erection position of neighbouring separate panels, are engaged with each other. In end sides there provided are slots; at that, those slots of two end sides being adjoined to each other correspond to each other and form the fixing channel for introduction of edge key. The latter protrudes above the slot end facing the longitudinal side of separate panel, and owing to movement of the outward protruding end of edge key to the slot it passes partially from slot to corresponding slot of adjacent separate panel.

EFFECT: reducing labour input when laying the covering.

The invention relates to a flooring according to characteristics of the restrictive part of paragraph 1 of the claims. In addition, the invention relates to a method of installation according to characteristics of the restrictive part of paragraph 24 of the claims.

Finished parquet, hardwood floors or laminate composed of many rows of flooring panels, mostly rectangular in its configuration. Usually panels have sex on one longitudinal and one end of the front sides of the grooves, and, respectively, at the opposite longitudinal end sides of the pins that correspond to the shape of slots. By connecting grooves and wedges is laying flooring panels, and panels of two adjacent rows offset from each other.

There is a method in which between the splines and grooves are formed by mechanical fixation, which provides the floor coatings locking coupling adjacent flooring panels with each other. Due to this, the formation of joints laid in the floor coatings prevented the processes of elongation or shrinkage. On the groove and the key flooring panels perform a match fixing elements in the form of recesses, grooves or ridges, to the United panel in the dock position was maintained without glue.

In this regard, the process of mounting panels spragens difficulties. If the mechanical fixing elements between the grooves and wedges first grappled with each other at one longitudinal and one end side, it often creates difficulties in obtaining connections with geometric circuit corresponding to other parties. Typically, panels twist or zamalchivaut each other along the longitudinal sides and subsequently tilted to the side, so that the locking strap is engaged with the front sides of the panels. To make this easier, you can inflict on the opposite side light blows with a hammer through the support bar. However, there is a danger that this may lead even with careful work to damage flooring panels.

These problems in the framework of the utility model DE 202005012603 U1 been taken into account due to the fact that the end faces of the panels were made grooves, and the grooves of the two abutting end sides meet each other and form a channel, which is then inserted key, which overlaps the joint between the two panels, so the connection between the panels is stabilized. The key will provide the highest permissible load in the joint area in the vertical direction.

A similar proposal is subject to DE 10138285 A1. There is described that the overlapping joint of the locking element can be entered in the space provided for it is yemco using sadhane or clogging. It is possible to calculate such tolerances of the locking element and the notches that the locking element will be inserted easily or tight in the corresponding slot.

Alternative additional input locking element or a special key on the end side of the proposed EP 1650375 A1. With this solution in the groove one end side is key of elastic plastic. The key is taken for the upper part and at the insertion of one connected on the end side panels fully unbent her in a holding groove and drops due to the elastic properties of the plastic into the corresponding slot on the front side of the next panel, connecting them to each other with fixing. With this method there is no additional insert the end of the key.

The basis of the invention lies task to improve flooring, consisting of individual panels, from the point of view of method. Next will be shown providing this as an improved method of installation.

The task regarding coverage is solved by the characteristics of paragraph 1 of the claims. The method of installation, which solves this task is the subject of paragraph 24 of the claims. The preferred modification of the inventive idea are the subject of dependent claims.

The invention relates in particular to a mutual vertical fixing end with the Oron individual panels, along the longitudinal sides of which provides glueless connection groove-key. The principle of operation is based on the idea that through the process of longitudinal introduction front dowels in a face groove of the movable part of this key is deflected sideways. It is important that at least one third of the length of the end pins is engaged with the adjacent end of the groove. Mobile end key does not necessarily have to be executed as a single unit, and may be formed of different parts.

The length of the displacement in the longitudinal direction of the end of the groove should be preferably less than 10 mm and, in the ideal case, of such magnitude as the width of the longitudinal tabs separate panels, i.e. for example, from 1.5 to 4 mm, And the current portion of the end pins, protruding from the end of the groove, shall not extend beyond the outer edge of the panel, i.e. in particular not to extend beyond the lower retaining bar. In the locked position of the end pins are fully inside end of the slots and preferably close flush with the bottom of the dome-shaped longitudinal groove side. The end key can also be its end portion aligned with the contour of the bottom of the groove of the longitudinal side.

It is essential that the end key is pre-mounted in one of the grooves, practically does not project over the location is authorized from the side entrance into the groove and through this to some extent is located wholly within the groove, and it is only the end of the end tabs may protrude out of the groove above the opening in the longitudinal side individual panels. This end can also be described as the working part, which is provided in order to transfer the force in the longitudinal direction of the groove on the end plug to at least partially transfer it to the corresponding groove of the adjacent panel so as to secure separate panels to each other by the end parties.

End key in a pre-assembled condition, has a width which is less than the locking channel. If the grooves in the end faces have the same depth, then the end key should be as wide as deep, one of the grooves, this means that the width should be equal to the maximum of half of the width of the locking channel formed by the grooves. Of course, you can perform the grooves in the end faces of different depths. For example, a groove in which to enter the mobile part of the front dowels may structurally be only 50% of the depth of the other groove.

A significant advantage of this flooring is that irrelevant for more lowering and driving the end of the dowels in the locking channel. This process of lowering is associated not only with additional working operation, but requires in addition a good feeling is titelliste fingers, since this activity is carried out depending on the position of electrician over your head, but clearly at least near the floor. If the end key is pre-inserted into one of the grooves, fall off the previously described operations introduction or driving in front dowels, so that the speed of packing can be significantly increased.

Another advantage is that the mechanical key is inserted in a pre-condition does not project over the front side of the panel, i.e. in any case is not a hindrance during installation. Because of this, in the area of junction between the two end parties can one panel, which is opened in the longitudinal direction of the previous, already laid panel, other than the solution according to EP 1650375 A1, without effort to turn down. The alignment of the end sides in height does not yet lead to separation in the area of the locking channel so that adjacent panels can be again removed, if required by the terms of styling. Only when laying the next row of panels need to fill the protruding end of the front dowels into the groove, so that this end of the plug, at least partially passes from one groove into the corresponding groove of the adjacent panel. Thus, the grooves forming the locking channel or junction between the individual panels overlap and are connected to each other with fixing./p>

Fitting end wedges and grooves to each other is made so that the axial displacement of the end of the dowels should be as smooth as possible. That is, the roaming part of the front dowels while before this slide inside the groove, but can still be easily moved. But at the same time the gap should be small enough to move through the height of individual panels coupled to each other by the end parties, was the most excluded. To achieve this goal, it is possible those parts of the end pins, which protrude from the first groove and enter the corresponding groove of the adjacent panel, to perform with the same exact fit as the other moved only in the axial direction, the end sections of the key. This movement can be improved by reducing the friction of additional substances or coatings, which are located in the area of the contact surfaces of the parts or applied as, for example, mastic oil, etc.

The end key can be moved in the first embodiment, the against the elastic force, which is the reason that the end key at the subsequent undocking again will act as the rear end of the groove or hole, when viewed from the front side, again fully seated in the groove. So, the commit occurs against the elastic force, so that the end key in the locked position the Institute is energized. The elastic force can be created special elastic element, such as a spiral spring, or itself be caused by its own stresses used for end of key material.

In the case when the end key can not be clamped by the following panel in a fixed position, requires manual fixing, for example, is inserted into the fixing terminal in the longitudinal dome groove separate panel.

The previous implementation was based on the assumption that the opening of the groove for the front dowels lies at the height of the dome of the longitudinal groove side. Needless to say, it is also possible that the end grooves or locking groove positioned so that the hole, which is the end key is in the area of the locking flanges on the longitudinal side. Decisive is only that the end key to lock should have the ability to move in the longitudinal direction of the fixing groove.

Under the front side in the sense of the present invention should be understood end-side individual panels. End side is, as a rule, its shorter side, and in the case of a square single panel also includes one end side with an Allen key and longitudinal directions.

In the practical movement of the end key may, at the lower into the groove of zahoditye surface of crowding, so it moves sideways, in the direction of the respective groove. This surface of crowding in the toolbar or in the groove can be formed itself as part of the area of the base of the groove or the base of the groove, in particular, are chamfered. In other words, the depth of the groove varies in the longitudinal direction. If the depth of the groove varies continuously, the end plug may, to a certain extent, the role of the wedge, and it is facing the opening of the groove longitudinal direction of shear in the axial direction uniformly out of the groove and is included in the corresponding groove of the adjacent panel. The surface of crowding is in this case the wedge surface. It is important that the depth of the groove was of such value to the end the key is in the locked state was unable again to slip out of the respective groove. Accordingly, the surface elevation of crowding or the surface of the wedge co-ordinate with the maximum shift distance, i.e. the length protruding from the groove end.

Fundamentally it is possible that the surface of crowding may also be rounded so that it does not have to be exactly linear. It is crucial that the function surface of crowding is that it acts as a continuous controvery when lateral displacement of the end pins during a longitudinally what about the move.

Flooring are often made out of wood and hence a relatively high amount of friction inside the groove. Can be an advantage if the surface of crowding is an integral part located in the groove of the wedge-shaped body front dowels. That is, if the end key is composed of two parts, and the key is divided into wedge-shaped body and the sliding part. The moving part is the segment length of the end pins, which is the end, protruding from the groove. Depending on the location of the surface of crowding is possible that either the moving part, or wedge-shaped body at least partially moves into the corresponding groove.

As of the end bearing separate panel is located, in particular, in the middle part of the face side, wedge-shaped body and the sliding portion may be approximately equal length, so that the surface of crowding and therefore, the moving area of the wedge-shaped body or the moving parts are also located in the middle part of the face side. In the preferred implementation should be approximately the middle third fixing groove at least partially fixed, in particular, if the panel is provided with a chamfer. Due to this, the friction of the mechanical key when moving less than if it acts on the entire length of the groove.

PR is a separate panel with a sharp edge or width of more than 200 mm, on the contrary, it is advantageous if many of the individual elements protrude from the groove, and is guaranteed fixation, particularly in the corner areas of the end joint.

An alternative possibility of overlap of the end joint in the zone of the clamping channel is seen in the fact that either the moving part, or wedge-shaped body wring out or perform squeezed through active mutual contact in the direction of the respective groove. Thus, for example, moving the wedge-shaped section is inserted in contrepartie wedge-shaped body, so that the sliding part comes between two elastic tongues, one of which is moved in the direction of the respective groove. This design has the advantage that the elastic impact springy shoulder again to displace the moving part back if the flooring will need to address. Due to this displacement of the fixation between the end sides automatically opens, and an operating end face of the key, again, is extruded from the groove, so that the flooring and the second time can be re-laid.

The following implementation provides that the groove receiving the end plug has at least one recess, in which the surface of crowding and which enters the projection of the end pins. This means that the groove is provided with an additional configuration in the form of the E. excavation for the formation of the surface of crowding. This implementation has a technological advantage, since on the one hand can be made a solid groove from the front side, in which you will need to make the notch. Very recess provided in the base of the groove. The recess may be, in particular, made with a saw, so that the contour of the recess may be part of a circle. This circular kerf in its transition zone to the base of the groove can also be struglin, so it's somewhat sinusoidal shape of the notches. This is not least due to the technologically because during processing, the individual panels are moving parallel to the blade, which is used to perform the extraction. If this movement is not completely in sync, it will lead to erosion in the area of the edges and, thereby, to the rounded transitions.

Theoretically it is also possible that the recess has the form of a pocket rectangular configuration, which is obtained by using finger cutters, or just a hole in the base of the groove and the surface of the crowding of holes on its edge limited, so in this case, the protrusions extending into the opening, come into contact with the surface of crowding only point.

In principle, provided that the protrusions create the least possible frictional resistance. It follows that the projections of at least narrower than the end key. Themselves protrusions can they the be the shape of a wedge or be rounded. It is important that the tab is that it allows the sliding surface of crowding or hinder him. The area of the protrusion in the direction of the surface of crowding should be at least some areas unilaterally oriented with the surface of crowding.

Theoretically sufficient to provide mechanical key, only a single projection, but it is preferable to provide at least two tabs, as in this case, maybe the parallel movement of the end pins. In particular, the end plug may have a protrusion on the end protruding from the groove. This ledge will come then to the corner of the groove, respectively, will slide along this angle, so that the end key will jump out of the groove. This ledge is preferably in the form of a wedge.

End key itself can be in order to reduce friction profiled wavy, and her wavy hand drawn decorative side and the underside of the separate panels. Optionally, you can provide mechanical key locking pins, through which the end key will point with clip to stay in the groove. Clamping pins serve as additional protection during transport and have a very small cross section. They are provided only to give the end key a strong position before the shift or papadaki the m in the groove. Additionally, on one of the longitudinal sides of the end key, you can perform a facet, which will facilitate the introduction of the end pins in the groove of the adjacent panel during the commit process.

Whereas the first laying it seems appropriate to end the key is made regarding the functional elements are composed of two parts, had given place of destruction, in which these functional elements, i.e. the moving part and a wedge-shaped body, are connected to each other. Thus it is guaranteed that during the transportation and installation of any item in the front dowels do not accidentally fall out of the slots. With the introduction of front dowels into the groove, that is, during installation, it is given a place of destruction can be destroyed.

In the framework of the invention it is also possible that the end plug is made of elastic plastic and moving stickout inside the arcuate groove is curved so that the curved section is included in the connection with the neighboring separate panel. With this configuration, also springing used plastic ensures that the end key again fall fully within its original groove, so that the flooring again can also be stacked without additional problems.

In another embodiment, provided that the end key has two shoulder, soy is anenih each other through a hinge, moreover, the plot of these shoulders in the area around the hinge when the movement of the protruding end of the inside of the groove may enter into connection with the corresponding groove of a separate panel. In the application of plastic hinge can be understood film hinge. This form of execution has the advantage that the force to move the front dowels smaller than that of the end pins, which should all curved to bend. Bending shoulders with this implementation does not occur. Bent only film hinge between the shoulders, and the need for this power is minimal. The hinge may be, however, the force of the return, which is so big that the end key fully again springs to the original groove.

Corresponding to the invention, the flooring may be fixed on the end side, mostly manually. That is, after laying hands rows of panels and using hand tools, for example by means of metal brackets, you can press on the end face of the key, it fell into the groove and to the junction in the area of the locking channel was blocked.

As a special advantage can be seen that the fixation on the end side by means of a laying under paragraph 24 of the claims. In this way laying the connection is done almost automatically due to the laying of the following is the first of a number of individual panels, which overlap with the rear side of the joint area between the previously laid row of panels. According to the proposed method provides that the end faces are only recorded when the following separate panel longitudinal sides engages with the previous number of panels, and on its longitudinal side extending from the groove end of the front dowels vidvigayt in the groove, so that it is orthogonal to the shift direction comes into lying opposite the groove of the other end side, and these individual panels will be fixed relative to each other by the end parties.

If the end key is configured such that it is removing the load back to the original groove, i.e. if the end of the end key again will automatically protrude out of the groove, it will automatically disconnect at the opening of the flooring. This is a decisive advantage compared to known methods of laying, in which the end pins must be removed by moving individual panels relative to each other.

In another implementation provides that the end key is composed of several parts, which, however, are connected with the connecting element to each other without the possibility of their loss. For example, the connecting element may be acting over the groove of the plank, which posledstviya front dowels into the groove still stands above the groove and only within the final processing are cut with a cutter or otrivautsa, so in the groove remain not only related to each other part of end tabs. This method simplifies the work with end plates during the manufacturing process.

Fundamentally it is also possible in the case of individual panels of sufficient thickness within a positioning groove for guide means for the front dowels, as, for example, the guide sleeve, in which, to a certain extent, like the bolts can be inserted end key.

End key in the uncommitted state should not act on or decorative covering layer separate panel, that is, must not be visible from above, so that it was not a hindrance during transportation or further manipulation of individual panels.

Material for the end plates may be wood, that is, we can talk about how natural the tree, and the material containing wood fibers. Metals and metal alloys as well as composite materials, may also be used. Using bimetals and hybrid composites it is also possible, as is the use of materials based on thermoplastic and thermosetting plastics. The end key can be performed, in particular, from glass fiber plastic fiber content from 20% to 60%.

The inventive idea is applicable to all systems of the sexes, in which the upper floor is located on the media, like the natural wood surface, laminate, media patent upper surface as an upper covering, linoleum, cork on the bearing plates, etc. Covering layer may consist, in particular, from the decorated paper, coated overlay that defines the appearance of the individual panels. Speaking about sexual coatings can be due parquet floors, finished hardwood floors, real wood floors or laminate floors.

The invention is hereinafter explained in more detail in the above examples, depicted in the schematic drawings.

Figure 1 shows a flooring consisting of multiple stacked in connection rectangular panels 1. Panel 1 provided at each of its end sides 2, 3 and the longitudinal sides 4, 5 of the fixing plate. The locking plate in the mounting position adjacent panels are engaged with each other.

Retainer strap 6, 7 on the front side 2 or 3 separate panels 1 are visible in figure 2. Figure 2 shows a vertical cross-section end side in the region of a joint between two separate panels 1, so you can see the connection on the end sides 2, 3. Not shown locking strips on longitudinal sides of a single panel 1 may have a different configuration than the locking strap 6, 7.

A separate panel 1 consists of a carrier layer 8 is made of a fibrous material, usually from a high or sredneprotsentnyh fiber plates, and the supporting layer 8 is provided on the upper side of the covering layer 9 and on the lower side of the compensating layer 10. The covering layer 9 may consist of decorative paper overlay that defines the optics of the floor panel 1. The so-called overlay or print form impregnated with a special resin useful layer that provides a floor panel 1 high wear resistance surface. Compensating layer 10 on the lower side of the base layer 8 serves for stability and moisture resistance.

p> Each individual panel 1 has a retaining bar 6 (the first retaining bar on one end side 2 (1-I end side) and the locking bar 7 (2nd retaining bar on the opposite side 3 (2-I end side). The first locking strip 6 has an open bottom of the first dome-shaped channel 11, and the downward end of the first domed protrusion 12. The second retaining strap 7, which lies on the opposite of the 2nd side 3 separate panel 1 is from the floor and stands relative to the base layer 8. The bottom side 13 of the second retaining strap 7 is held in the plane of the bottom side 14 separate panel 1. The second retaining strap 7 is open up the 2nd dome channel 15 and upward end of the 2nd dome projection 16.

We are in engagement of the first locking strap 6 and the second retaining strap 7 1st domed protrusion 12 is in the 2nd dome channel 15, and the 2nd dome-shaped projection 16 is in the 1st dome channel 11. When it come into contact facing each other and arranged with an inclination in one direction lateral sides 17, 18 of 1st domed protrusion 12 and the 2nd dome projection 16. Occurs, thus, the center of pressure on the lateral sides 17, 18, which creates a force that carries out contraction with each other both locking bars 1 in the area of Pokrywa the future of the layer 9, thus the change in the joint area between the two flooring panels 1 on the covering layer 9 is almost seamless.

In the end faces 2, 3 individual panels 1 made grooves 19, 20, which pass through the entire length of the end sides 2, 3. As you can see in figure 2, the grooves 19, 20 coupled to each other end sides 2, 3 correspond to each other and form a locking channel 21. In this retaining channel 21 is inserted shaded end plug 22. The grooves 19, 20 in the end faces 2, 3 are provided on the locking bars 6, 7 in the bearing layer 8.

Figure 3 shows a perspective image in the direction of the end side 2 separate panel 1. From this image you can see that the end key 22 in the pre-installation state is located completely within the groove 20 and, in particular, does not extend past the hole 23 of the groove from the front side. End key 22, however, is its end 24 in the area of the longitudinal sides 5 of the groove 22. Figure 3 is only approximately represented, as is the end key 22 in the groove 20. The method of operation and possible execution front dowels will be later explained in connection with Figure 4-10.

Figure 4 shows that the end key 22 when lowering into the groove 20 in the direction of the arrow P is coming to the surface 25 of crowding in the form of a wedge and, therefore, extends in the direction of the arrow P1 of the groove 20 and is not shown in detail about what atom engages in a corresponding groove 19 adjacent a separate panel 1, as shown in figure 2. Feature implementation in Figure 4 is that the groove 20 is not along the entire length of the end pins 2, so that the surface 25 of crowding formed directly by the base of the groove.

In the example run in Figure 4 only part of the base of the groove forms a surface 25 of crowding. But it is also possible that the base of the groove plays the role of the surface 25 of crowding, as shown in Figure 5. In this case, out of the groove 20 is not only the tail part of the mechanical key 22. Moreover, from the groove 20 all wedge-shaped end plug 22a extends almost parallel to the front side 2. This is shown by the arrows P1.

The form of execution by 6 shows a variant with an Allen key 22b, consisting of two parts, the sliding portion 26 and a wedge-shaped body 27. The moving part 26 and a wedge-shaped body 27 are connected to each other by analogy with the form of execution according to Figure 4 in the area of the wedge surface 25, so that by moving the sliding part 26 in the direction of the arrow R. the inner end of the sliding part 26 is rotated in the transverse direction to the arrow P in not depicted in detail, the groove of another individual panel 1. Arrow P1 indicates the direction of rotation.

The form of execution according to Fig.7 shows a variant with an Allen key 22c, consisting of two parts, in which the surface 25 of crowding reverse the tilt is on a wedge-shaped body 27a, so moving the moving part 26a in the direction of the arrow P causes the wedge-shaped moving body 27a in the direction of the arrow P1. Fixing it is not on a sliding portion 26a, and a wedge-shaped body 27a.

On Fig shows a wedge-shaped body 27b team pins 22d, whose end facing the moving part 26b has a V-shape. In this V-shaped end is inserted with the appropriate form of the head 30 of the moving part 26b. V-shaped end is formed with two elastic shoulders 28, 29, which become from each other head 30 of the moving part 26b when moving in the direction of the arrow P, so that one elastic shoulder 28 is extruded perpendicular to the direction of sliding of the groove 20 and is moved into the groove 20 adjacent a separate panel 1 to commit. At the same time also engages a portion of the head 30 of the moving part with the corresponding groove of the next individual panel 1.

Fig.9 shows a variant of the end pins 22e of plastic. End key 22e consists of two arms 32, 33 are connected to each other through a hinge 31. In the area of the hinge 31 of the shoulders 32, 33 beveled, so you get a V-shaped cut in the end the key 22e. Through this incision and the location of the hinge 31 can move the shoulders 32, 33 relative to each other, so that the area of the hinge 31 may be pressed into the groove of the next individual panel 1 is, thus, to facilitate vertical fixation of adjacent panels to each other.

Figure 10 shows, finally, the form of the end pins 22f of elastic material that can bend in an arc without the V-sections and hinges solely due to creation efforts in the direction of the longitudinal axis team pins 22f, so that the curved section is engaged with the corresponding groove of the next individual panels. Forms run on Pig and 10 have, in General, the advantage that due to elastic effects may automatically return end keys in the original groove.

11 and 12 show the end of the 24 end key 22g in uncommitted position (11) and in a fixed position (Fig). From the drawings it is clear that the end face 34 protruding end 24 end key 22g corresponds to the longitudinal contour of the dome of the channel 35, which is in this case made concave. We can then see that the end key 22g in the uncommitted state does not act on the decorative or cover layer separate panel 1, so that the end key 22g top is not visible and does not create any interference during transport, handling and stacking of the individual panels 1. Fig and 14 show a variant of the front dowels 22h, which consists of three parts. The rear part of the front dowels 22h scale is and with the sides of the groove 20, so that it cannot move in the longitudinal direction of the groove 20. The rear portion may also be referred to as a wedge-shaped body 27c. Wedge-shaped body 27c serves as a counter for the middle part of the trapezius, which acts as a locking element 36. Unlike the previous embodiments in that case, however, moved in the longitudinal direction of the moving part -26 C does not go in the direction of the groove, but only moves the locking element 36, which is based on klinovuyu surface of the wedge-shaped body 27c and klinovuyu surface of the sliding part -26 C.

On Fig-17 shows a variant of the end pins 22i, which contains the sliding portion 26d and this guide sliding part 26d of the sleeve 37. Moving part 26d can be moved against the action of the elastic force of the spring 38 within the sleeve 37. When this spring is supported on the bottom 39 of the sleeve 37. The sleeve 37 has side holes 40, which are arranged such that they are in the pockets 41 of the moving part 26d fixing elements 42 under the influence of the elastic force can be rotated outwards and thus does not depicted in detail by way engages with the groove of the next individual panels to produce the coupling end parts of adjacent individual panels. This kind of end pins 22i can be used as a pre-installation site, in particular, in the thick the x separate panels and allows a reliable and reversible fixation between the end grooves.

On Fig shows a variant of the front dowels 22j, which again is in the slot 20 separate panels 1 and is also moved in the direction of the arrow P when you commit two separate panels and protrudes out of the groove 20 in the direction of the arrow P1. Thus there is a parallel motion of the front dowels 22j, which is defined by two projections 43, 44, which are towards the base of the groove 20. The first protrusion 43 is in the transition region from the middle to the left, in the plane of the drawing, the third front dowels 22j. The protrusion 43 has a triangular shape and fits into a recess 45, which has the shape of a circular sector. The recess 45 may be performed, for example, by using a flat blade which is inserted into the groove 20. The ledge 43 corresponds to the depth of the recess 45 so that the end key 22j in the uncommitted state adjacent to the bottom of the groove. While its front end 24 does not act on the individual panel 1. This front end is the second protrusion 44, which runs in the longitudinal dome-shaped channel 35. The protrusion 44 is coming on with a 90 degree angle in the transition zone between the longitudinal dome channel 35 and end groove 20. As the motion path is small, the second protrusion 44 is shorter, respectively, is not so far in the direction of the dome of the channel 35, as the projection 43 provided for this purpose in the recess 45. Geometry is Stepov 43, 44 can be aligned with each other, possibly parallel motion of the front dowels 22j.

On the basis of Fig we can further see that several of the clamping pins 46 are distributed along the length of the front dowels 22j. The locking pins 46 are small tabs on the top or bottom side of the front dowels 22j and serve to hold the clamp in the position shown.

The form of execution according Pig different from the above Fig the fact that the notch 45a has a smaller depth than the forms run on Pig, and the protrusions 43a, respectively, for short.

Another difference is that in the example of execution according Pig has two rounded notches 45a and, accordingly, the two tabs 43a, so that the end key 22k in this exemplary embodiment has an additional bearing into the groove 20.

Fig shows the end plug 22k on the front view. In this perspective image again shows that the end key 22k performed wavy to the upper and lower sides of the groove 20, so that the contact surface of the front dowels 22k with a groove 20 is reduced, to reduce friction. Moreover, it is clear that the locking pins 46 are located on the upper side and the lower side of the front dowels 22k, and they keep it inside of the groove 20. Further, it is clear that indicated by the dashed lines, the grooves 43a have a width of enshou, than the width of the main body front dowels 22k to make as small as possible the friction between the lip 43a and the surface of crowding within the recess 45.
