Description

  • The invention relates to a locking device for building panels, in particular floor, wall or ceiling panels, according to the preamble of claim 1.
  • Currently, various systems of edge geometries are known as floorboards formed building panels, which is based on locking the head edge in the longitudinal direction usually by push-button systems or snap-locks. In push button systems, a pressure point must be overcome, which opposes only low holding forces against the release of the compounds. In the case of snap connections, the floorboard that has already been attached to one edge must be inserted laterally at an angle into the connection of already laid floorboards and then swung down to be joined at the other edge. This shifting means for the publisher uncomfortable work with additional necessary tools.
  • Other known systems have an additional component which allows joining of planks. The disadvantage of such systems on the one hand, the additional required component, which causes additional costs and on the other hand, a reduced fit due to adding tolerances of the various components.
  • A locking device goes out of the DE 101 59 284 B4 out. The known locking device has groove side recesses, while spring-side locking projections are provided. The recesses allow insertion into the projections, so that in principle results in a joint connection. Subsequently, the floor panels are moved relative to each other in the known method, so that the locking projections leave the area of the respective recess and results in a bayonet-type connection.
  • A disadvantage of the known locking device is that the recesses in the edge region for the publisher are not readily apparent, since they are located at the front end in the lower region of the upper groove leg. Due to this concealed arrangement, it sometimes takes a certain time until the publisher has pushed the projections in the recesses of the upper groove legs. In addition, the insertion of the spring into the groove requires a corresponding space requirement, which corresponds at least to the depth of the joint. In some applications, however, extremely little space is available, so that the joining of two known panels causes difficulties.
  • A locking device of the generic type goes out of the WO 2009/116926 A1 out. The locking device has a spring and a groove on a first edge of a first building panel at an opposite edge of a second building panel, so that the edges can be vertically connected to each other. The spring and the groove are slidable relative to one another, the spring having a projection which extends horizontally behind the upper region of the edge. In addition, the spring has a further projection and a receptacle, so that the adjacent edges can assume a vertical non-locking position in which the projection of the spring engages in the receptacle of the groove and can assume a locking position in which the projection of the spring vertically overlaps the projection of the spring.
  • The disadvantage is that a large number of processing steps for connecting the plates is necessary. In addition, the insertion of an upper plate is difficult on a resting on the ground further plate due to the edge geometries of the plates.
  • Object of the present invention is therefore to provide a locking device of the type mentioned, which can be produced in a simple manner and which allows easy joining of the components.
  • The above object is achieved in a locking device according to the invention according to the preamble of claim 1, characterized in that the locking cam against the end face of the upper groove leg of the first edge and that a stop surface ( 24 ) of the locking cam ( 26 ) is set back relative to the groove base and that the lower groove leg is set back relative to the end face of the upper groove leg, so that at the first edge results in an overall oblique, falling from top to bottom contouring.
  • Constructively, the locking device mentioned above is realized in that the spring at least one spring interruption and at least one spring portion and the lower groove leg have at least one Nutunterbrechung and at least one Nutschenkelabschnitt, so that the first building panel by vertically passing the Nutschenkelabschnitts by the spring interruption from above to the second Building plate can be attached and the building panels by lateral displacement, ie moving in the longitudinal direction of the edge, at least one of the building panels with simultaneous, at least partial overlap of a spring portion with a Nutschenkelabschnitt are lockable. The locking takes place at least in the vertical direction, preferably in the horizontal direction.
  • In the invention, it is such that the joining of two adjacent building panels is made possible by the fact that short sections of the existing geometry are removed on the two sides to be joined, so that a toothed geometry arises on both sides. The arrangement of the interruptions or recesses is coordinated so that the geometry alone does not enter into each other when nesting the building panels, but only when moving one of the building panels in the direction of the later position, a lock occurs. Ultimately, it is in the invention so that can be completely dispensed with the necessary in the prior art joining space for joining, for example, two top edges, since in the invention, a supply in the joining region from above is possible. As a result, a very simple and space-saving joining of adjacent building panels is possible in the invention.
  • By means of the invention, however, not only is it possible to lock adjacent building panels in the vertical but also in the horizontal direction. Structurally, it is provided in this connection that locking means for locking the building panels in the horizontal direction are provided on the first and on the second edge of building panels to be connected to each other and that at least one corresponding interruption and at least one corresponding section are respectively provided on the locking means, so that the building panels by lateral displacement, so moving in the longitudinal direction of the edge, at least one of the building panels in the horizontal direction can be locked. Finally, the sections and interruptions of the locking means at the first and the second edge of the dimensions forth the aforementioned sections of the spring and the groove leg or the interruptions of the spring and the groove legs, so that in the joining of adjacent building panels ultimately in both vertical than also in the horizontal direction results in a lock or a positive connection.
  • In a preferred embodiment, a downwardly projecting locking cam portion of a locking cam is provided at the first edge outside the groove and below the lower groove leg, while at the second edge below the spring portion a spring separate upwardly projecting locking projection portion of a locking projection for cooperating with the Locking cam portion is provided. The aforementioned embodiment with the spring-separate locking projection or the one or more locking projection portions has the advantage that the horizontal and the vertical locking function is decoupled and taken over by different elements.
  • In connection with the aforementioned embodiment, it has proved expedient both in terms of manufacturing technology and from the publisher's point of view that the locking cam is set back relative to the end face of the upper groove leg of the first edge and / or the groove bottom, while the end face opposite the end face of the first edge the second edge and / or the spring end is set back relative to the locking projection. In this way, an oblique edge geometry results at both edges, which, as stated above, has a favorable effect on the edge processing and incidentally shows the publisher immediately at which point the joining of adjacent building panels has to take place.
  • Instead of dividing the locking functions in the vertical and horizontal directions to different, separate elements, it is also possible in principle, that at the first edge within the groove on the upper and / or lower Nutschenkelabschnitt a locking projection portion which may be formed by a further groove provided is at the second edge on the spring portion, a protruding locking cam portion is provided for cooperation with the locking projection portion. In this case, then concentrate the individual locking means on the spring or the or the spring sections and the groove or the individual groove sections.
  • In order to keep the lateral displacement when joining adjacent building panels as low as possible, it makes sense, a plurality of spring sections and / or Nutschenkelabschnitten and / or Locking cam portions and / or locking projection portions provide. The individual sections can each have a length in the longitudinal direction of the edge of greater than 0.5 cm, each individual value greater than 0.5 cm is possible. The length of the individual sections is preferably between 0.5 and 2.0 cm. By the length of the individual sections or the length in the longitudinal direction of the edge of the individual interruptions, the displacement path for locking the respective edge is defined in a plurality of sections and interruptions. Depending on the application, therefore, the lock can be adapted to the width or the length of the building panel.
  • Furthermore, it is particularly advantageous if the spring section and the groove leg section and / or the locking cam section and the locking projection section in the joined, locked state overlap each other at least substantially completely. In the assembled state then there is an optimal lock. Incidentally, in this context, the length of the spring section (in the edge longitudinal direction) of the length of the groove interruption and the length of the Nutschenkelabschnitts the length of the spring interruption should at least substantially correspond. In the same way, this applies to the length of the locking cam portion and the locking projection portion with respect to the related interruptions.
  • Finally, it is preferred in the embodiment according to the invention that the spring sections and the locking projection sections are arranged one above the other in the region of the second edge and are separated from adjacent sections by the interruptions arranged therebetween, wherein the interruptions merge into one another in the vertical direction. In the same way, this applies to the Nutschenkelabschnitte and the locking cam sections.
  • In order to prevent inadvertent displacement of joined building panels and to ensure a play-free arrangement, the distance of the end face of the upper groove leg of the first edge to contact point / stop surface of the locking cam portion at least substantially equal to the distance of the end face opposite end face of the second edge to the contact point / stop surface the locking projection portion.
  • In addition, it can be provided that the clear distance of the groove legs and thus the groove height of the thickness of the spring corresponds at least substantially. In this way, a displacement of the building panels in the vertical direction can be prevented without play.
  • With regard to the division of the locking functions in the vertical and horizontal directions on different elements is additionally provided that adjoins the locking cam portion, a lower contact surface and that adjoins the locking projection portion an upper abutment surface, wherein the distance of the lower abutment surface to the groove surface of the lower groove leg the distance of the upper contact surface to the lower spring surface at least substantially corresponds. This design ensures that a closed surface of the building panels in the upper gap area can be guaranteed.
  • The inventive design of the locking device can be realized both on the head and on the longitudinal edges and the rest both on the top and longitudinal edges of the building panels.
  • Especially when the locking device according to the invention is provided on the longitudinal sides of a building panel, it is possible to relocate the plates without a building plate would have to be tilted during installation. Thus, an embodiment of the method according to the invention provides that a number of building panels connected to one another are inserted with their longitudinal edge region into the longitudinal edge region of a row of already laid building panels transversely to the longitudinal side from above or in the plane of the already laid building panels and subsequently displaced in the direction of the longitudinal side is, so that then results in a locking of the building panels in the horizontal direction.
  • Prerequisite for the joining of a series of building panels is that the individual building panels are already connected to each other at their top ends. This can be done via conventional joint connections or else via a locking device according to the invention. Then the series is then applied to the already laid building panels and locked by a corresponding displacement bayonet-like.
  • Incidentally, it is such that the locking device according to the invention can be produced at both edges in a simple manner. Thus, the lower groove leg portions and the locking cam portions at the first edge and the spring portions and the locking projection portions at the second edge are respectively aligned. The interruptions between the individual sections of the first and the second edge can each be produced with a rotating milling tool in one step, which realizes a circular path-shaped recess or interruption. In order to ensure the functionality of the edge geometry, it has been found that there is a geometric relationship between the thickness or thickness of the building panel on the one hand and the length of the geometry according to the invention. It is essential in particular that the upper groove leg may not be damaged on its front side during processing. The geometry length of the respective edge has an influence on the milling tool to be used, so that there is a further relationship between the thickness of the building panel and the tool diameter.
  • For the inventive geometry of the edges, this relationship between the radius of the milling tool, which ultimately corresponds to the radius of the relevant milling surface at the edge, and the thickness of the building panel in a ratio R: D between 2.5: 1 to 3.5: 1 , preferably between 2.8: 1 to 3.4: 1 and in particular between 2.9: 1 to 3.33: 1.
  • It has been found that for the following thickness of the building panel the tool diameter should be as follows: Thickness [mm] Resulting diameter [mm] Selected diameter [mm] 6 36 (R = 18) 40 (R = 20) 7 42 (R = 21) 40 (R = 20) 8.1 48.6 (R = 24.3) 50 (R = 25) 9 54 (R = 27) 55 (R = 27.5) 12 72 (R = 36) 70 (R = 35) 25 150 (R = 75) 150 (R = 75)
  • It is understood that each individual value is possible for itself.
  • Incidentally, in connection with the above-mentioned table, it should be pointed out that although it is fundamentally possible to produce milling tools with the resulting tool diameter, it is more expedient and less expensive to resort to common diameters of milling tools which are indicated in the right-hand column.
  • Hereinafter, embodiments of the invention will be explained with reference to the drawing. All described or illustrated in the figures features alone or in any combination with each other, the subject of the present invention, regardless of their combination in the claims or the description. It shows:

  • In the 1 and 2 is a locking device 1 between a first building plate 2 and a second building plate 3 shown. The locking device 1 ultimately provides a given geometry at a first edge 4 the first building plate 2 and a second edge 5 the second building plate 3 represents.
  • It should be noted that every building plate 2 . 3 the locking device 1 as such on opposite sides, since the edge geometry of the second edge 5 at the first edge 4 opposite side of the first building panel 2 is also realized. Likewise, the edge geometry is the first edge 4 the second building plate 3 on the opposite side of the second edge 5 realized.
  • Incidentally, it is so and this arises from the 5 ff, that each of the building panels 2 . 3 a rectangular plate body with long sides 6 and head pages 7 having. It is so that the opposite longitudinal sides 6 or the opposite sides of the head 7 each have a mutually corresponding, complementary contouring, as for example in the 1 and 2 is shown.
  • It should be noted, moreover, that in the 1 and 2 illustrated geometry, for example, the edge 4 both at a longitudinal or at a head edge 6 . 7 or on both edges 6 . 7 can be realized.
  • The plate body, the core of which may consist of a wood material such as wood fibers, for example, usually has an elongated rectangular shape. At the building plates 2 . 3 as such, it may be floor, wall and / or ceiling panels.
  • At the locking device 1 is at the first edge 4 a groove 8th and on the opposite second edge 5 one to the groove 8th corresponding spring 9 intended. The groove 8th has an upper groove leg 10 and a lower groove leg 11 on.
  • In the illustrated embodiments, it is now so that the spring 9 at least one spring interruption 12 and at least one spring section 13 having. As it turned out 3 yields, the spring points 8th a plurality of spring interruptions 12 and spring sections 13 on. The upper groove leg 10 is continuous and extends at least substantially over the entire length of the edge 4 , The lower groove leg 11 is corresponding to the spring 9 educated. He has at least one Nutausbrechung 14 and at least one groove leg portion 15 on.
  • As can be seen for example 4 results are a plurality of groove interrupts 14 and groove leg sections 15 intended. In this case, the number and length of the spring interruptions corresponds 12 with the number and length of groove interrupts 14 while the number and length of the spring sections 13 the number and length of Nutschenkelabschnitte 15 equivalent.
  • The aforementioned training, which ultimately leads to a toothed edge both at the first edge 4 as well as on the second edge 5 leads, that allows the first building plate 2 by vertically passing the individual groove leg sections 5 through the spring interruptions 12 from above, ie in the vertical direction, to the second building plate 3 attachable and the two building panels 2 . 3 then by lateral displacement, so moving in the longitudinal direction L of the edge, at least one of the building panels 2 . 3 are lockable. Ultimately, a relative movement of one to the other building plate 2 . 3 required in the lateral direction. This then results in an at least partial overlap of the individual spring sections 13 with the groove leg sections 15 , which leads to a lock at least in the vertical direction. In the illustrated embodiments, it is such that in a proper joining, ie in an aligned system of building panels 2 . 3 on or to each other, a complete coverage of the spring sections 13 with the groove leg sections 15 results. This will be discussed in more detail below.
  • In addition, at the first edge 4 and the second edge 5 the building panels 2 . 3 and thus on opposite sides of every single building slab 2 . 3 each locking means for locking the building panels 2 . 3 provided in the horizontal direction. The locking means in the horizontal direction make use of the aforementioned principle of the toothed edge geometry, namely they each provide at least one corresponding interruption and in each case at least one corresponding section, whereby it is possible to use the two building panels 2 . 3 by perpendicular lowering of a building plate relative to the other building plate in the common edge area engage with each other, without first locking them, and by laterally moving in the longitudinal direction L of the edge of at least one of the building panels 2 . 3 to lock in the horizontal direction.
  • In the in the 1 to 4 illustrated embodiment is in this context at the first edge 4 outside the groove 8th below the lower groove leg 11 a locking cam 16 provided, which protrudes downwards. The locking cam 16 is divided or interrupted in the same way as the lower groove legs 11 and accordingly has one of the number of groove leg sections 15 corresponding number of locking cam sections 17 on. Between the individual locking cam sections 17 There are corresponding cam breaks 18 ,
  • Corresponding to the locking cam 16 is at the second edge 5 below the spring 9 one from the spring 9 separate, upwardly projecting locking projection 19 provided with the locking cam 16 interacts. The locking projection 19 is over a channel 19a from the spring 9 separated. The locking projection 19 is interrupted in the same way as the spring 9 and has a corresponding number of locking protrusion sections 20 on. Between the individual locking projection sections 20 there are protrusion breaks 21 , The extension of the locking cam sections in the longitudinal direction L of the edge corresponds to the length of the individual groove leg sections 15 while the length of the cam breaks 18 the length of the respective groove interruptions 14 in the longitudinal direction L correspond to the edge. In the same way is the opposite, second edge 5 educated. This corresponds to the length of the spring sections 13 the length of the locking projection portions 20 in edge longitudinal direction L, while the length of each spring interruptions 12 each of the length of the projection interruptions 21 equivalent.
  • As already mentioned, the upper groove leg extends 10 at least essentially over the entire edge length. The upper groove leg 10 thus has no interruptions, which ensures that the building panels 2 . 3 in the joined state have an at least substantially closed surface in the edge region. Only the joint gap 22 between the two building panels 2 . 3 remains.
  • As, moreover, in particular from the 1 and 2 gives, is the locking cam 16 opposite the face 23 of the upper groove leg 10 the first edge 4 set back. The stop surface 24 of the locking cam 16 is beyond even the bottom of the groove 25 set back. In this way results at the first edge 4 ultimately an overall oblique, ie falling from top to bottom contouring. In contrast, at the second edge 5 a complementary, generally obliquely increasing contouring provided. It is the face 23 the first edge 1 opposite end face 26 the second edge 5 opposite the locking projection 19 set back. Also the spring end 27 is opposite the stop surface 28 the locking projection 19 set back. The overall oblique contouring of the first edge 4 and the second edge 5 offers on the one hand manufacturing advantages in edge profiling and distributes the rest of the functions of the vertical locking on the tongue and groove connection with the elements 8th . 9 and the horizontal latch over the locking cam 16 and the cooperating locking projection 19 ,
  • Otherwise, the result is in particular 3 that at right angles to the second edge 5 - and thus to the first edge 4 - extending further edge 29 has a different from the edge profiling of the first and second edge profiling. The further edge 29 can be on the longitudinal or the head side 6 . 7 be provided the building plate. Here is a joining groove 30 and a locking groove 31 intended. At the in 3 illustrated embodiment, the joining groove extend 30 and the locking groove 31 over the entire length of the further edge 29 , It is understood that on the further edge 29 opposite side of the relevant building panel one to the joining groove 30 complementary spring and one to the locking groove 31 Complementary locking projection are provided.
  • As, moreover, from the 1 and 2 results, the distance corresponds to the end face 23 of the upper groove leg 10 the first edge 4 to the stop surface 24 of the locking cam 16 at least substantially the distance of the end face 26 the second edge 5 to the stop surface 28 the locking projection 19 , Incidentally, the clear distance corresponds to the groove legs 10 . 11 the thickness of the spring 9 , In this way, both in the horizontal and in the vertical direction at least essentially a backlash.
  • Furthermore, it follows from the 1 and 2 that attach to the locking cam 16 a depression 40 followed. The depression 40 serves to receive the locking projection 19 and has a lower abutment surface 41 on. Corresponding to the contact surface 41 is on the locking projection 19 an upper contact surface 42 intended. In the joined state are the contact surfaces 41 and 42 to each other. The distance of the lower contact surface 41 to the groove surface 43 of the lower groove leg 11 at least substantially corresponds to the distance of the upper contact surface 42 to the lower spring surface 44 ,
  • As can be seen moreover from the individual figures, it is possible to use the locking device 1 only on the long sides 6 ie on the long sides of the building panels 2 . 3 , or only on the sides of the head 7 ie on the short sides of the building panels 2 . 3 , or alternatively on the longitudinal and on the sides of the head 6 . 7 the building panels 2 . 3 provided.
  • Is the locking device 1 only on the long sides 6 provided, they have the edge profiling according to the edges 4 . 5 on. The same applies if only the head pages 7 the building panels 2 . 3 with the locking device 1 are provided, so the profiling according to the edges 4 . 5 according to the 1 and 2 exhibit. It can then be the long sides 6 with a profiling according to the other edges 29 . 33 be provided. Incidentally, it is understood that it is also possible in principle, a different profiling than the edges 29 . 33 provided. When the locking device 1 both on the longitudinal and on the sides of the head 6.7 the building panels 2 . 3 is provided, then the profiling according to the 1 and 2 intended.
  • In the 1 and 2 dashed lines indicate that the first edge 4 and also the second edge 5 has been processed with a rotating milling tool. The dashed line indicates the milled surface 45 . 46 at. The radius R of the surface 45 . 46 Ultimately, this corresponds to the radius of the rotating milling tool. The ratio of the radius R of the milled surface 45 . 46 stands in a ratio R: D to the thickness D of the building panels 2 . 3 in the range between 2.5: 1 to 3.5: 1. The actual value ultimately depends on the thickness of the building panel and the available milling tool.
  • As 3 clarified in this context, is from the milling tool in a process both the upper spring interruption 12 as well as the lower projection interruption 21 produced. Between the individual interruptions 12 . 21 remain in the form of teeth, the spring sections 13 and the locking protrusion portions 20 , In the same way, the production of the interruptions takes place 14 and 18 , being between the breaks 14 . 18 located Nutschenkelabschnitte 15 and locking cam sections 17 are located. This is evident 4 , The 3 and 4 as a result illustrate that the interruptions 12 . 21 through the continuous milling surface 46 arise while the interruptions 14 . 18 through the milled surface 45 result.
  • In the 5 to 10 is a possible installation variant of building panels according to the invention shown. In this installation variant building panels are used, in which the locking device 1 on the long sides 6 is provided. At the top of the head 7 is a contouring realized with a snap connection. In the present laying variant, it is so that the building plate 32 already laid. Although only a building plate 32 It is understood that in the row of the building plate 32 a variety of other building panels 32 can be provided. Furthermore, the building plate 3 already laid. There is a shift from left to right.
  • In 5 Now the state is shown, in which the building plate 2 is lowered in the vertical direction from above at coverage in the common edge area. In this case, then enter the Nutschenkelabschnitte 15 through the spring interruptions 12 until the building plate 2 on the ground on which the building plate is 3 already located, also located. This condition is in 6 shown. Subsequently, the building plate 2 until the contact of the head side 7 to the corresponding head page 7 the building plate 32 moved forward in the direction of the arrow. When moving the building plate 2 relative to the building plate 3 there is a lock in the area of the long sides. This condition is in 7 shown. In this condition is the building plate 2 not yet locked on its head side.
  • Subsequently, the building plate 2 . 3 bent to swing in the top edges. The already lying building plate 2 will be raised again. This condition is in 8th shown. Then the building plate 2 pushed in the direction of the arrow until the upper edges of the head sides 7 the building panels 2 and 32 touch. This results in a locking connection between the head pages 7 the building panels 2 and 32 , This condition is in 9 shown. Subsequently, the building panels 2 . 3 lowered, so that there is a complete locking of the building panels.
  • In the 11 to 15 is a laying variant shown in which the locking device 1 only in the area of the head pages 7 located. In the area of the long sides 6 there is a snap connection. The individual figures show not only top views of a building plate arrangement as a whole, but below the top view also different side views.
  • In 11 is shown the state where the building plate 2 is lowered vertically from above in the arrow direction. In doing so, as previously described, the groove leg sections occur 15 through the spring interruptions 12 , As it turned out 12 results, the building plate becomes 2 then in the direction of the arrow in the direction of the already laid building panels 32 moved until the long sides 6 the building panels 2 and 32 to strike each other. As it turned out 13 results, the building plate becomes 2 then with her free long side 6 raised in the direction of the arrow. This is also the building plate 3 in some cases with raised. As it turned out 14 results, then pressure in the direction of the arrow on the free longitudinal side 6 the building plate 2 exercised, so that the opposite longitudinal side 6 with the long sides 6 the already laid building panels 32 comes into joining intervention. Finally, as it turns out 15 gives, the building plate 2 lowered in the arrow direction, so that the joining state results.
  • In the 16 to 21 an alternative installation variant is shown in which a whole series of building panels 2 . 3 is inserted. Shown is a laying from left to right, with the building plate 2 is first lowered vertically from above ( 16 ). The lowered state results from 17 , being in the area of the head edge 7 there is an offset. Subsequently, one of the building panels or both building panels is moved relative to each other, so that the in 18 shown state results. There is then a locking of the plates 2 . 3 in front. 19 shows that the entire series of building panels 2 . 3 is bent to swing in. It understands that the series is a plurality of building panels 2 . 3 can have. Subsequently, the entire series of building panels 2 . 3 pushed in until a touch of the upper edges of the building panels 2 . 3 with the already laid building plate 32 or the already laid row of building panels 32 results. This is in 20 shown. Finally, the series of building panels 2 . 3 lowered and there is a complete locking of the two rows of building panels. This is in 21 shown.
  • While the laying variant of the 16 to 21 refers to an embodiment in which on the long sides 6 the locking device 1 is intended, refers to the in the 22 to 27 illustrated laying variant on building panels, in which the locking device 1 on the head side 7 located.
  • Out 22 it turns out that the building panels 32 already laid in a row. The building panels 2 . 3 are not relocated yet. 22 shows the condition in which the building plate 3 is located on the ground and the building plate 2 is lowered in the direction of the arrow. It then results in the 23 illustrated state. Subsequently, the building plate 2 opposite the building plate 3 shifted in the direction of the arrow, so that then the in 24 shown state results. Then the row from the building plates 2 . 3 in the direction of the arrow in 25 bent. In 26 is the turn of the building slabs 2 . 3 with their longitudinal edges 6 to the longitudinal edges 6 already laid series of building panels 32 pushed up. It will then be on the long sides 6 the row of building plates 2 . 3 pressed in the direction of the arrow, as in 26 is shown. Finally, the series of building panels 2 . 3 swung down in the direction of the arrow, as in 27 is indicated. It then results in the joint connection between the rows of building panels 32 and the building panels 2 . 3 ,
  • In the 28 to 30 are shown building panels, where both on the long side 6 as well as on the head side 7 the contouring for the locking device 1 is provided. The viewer in 28 facing longitudinal side 6 has a contour corresponding to the second edge 5 on. The same applies to the viewer facing the head 7 , The opposite, the viewer facing away from the long side 6 and also the head side facing away from the viewer 7 has a contour corresponding to the first edge 4 on.
  • The 30 makes it clear that it is easily possible, according to individual building panels 28 to connect with each other. It is readily possible, according to the laying variant according to the 5 to 15 and also according to the laying variant of 16 to 27 to proceed.
  • However, a decisive difference from the installation variants described above is that angling of the building panel to be laid is no longer necessary. Joining can take place only in the plane, wherein the correct joining arrangement ultimately takes place by moving the relevant building panel or a series of building panels. So it is in the embodiment according to 30 for example, possible that already laid building plate 32 or a series of already laid building panels 32 first the building plate 3 either inserted and locked from above or in the plane of the building panels 32 is inserted and then locked by lateral movement. Then the building plate 2 from above or in the plane of the building plate 32 in the head side area of the building panel 3 inserted and at least slightly laterally displaced until a lock between the plates 2 . 3 results. Then the row of building plates 2 . 3 so far in the longitudinal direction L shifted that the building plate 2 with its long side 6 in the edge area of the long side 6 the building plate 32 can be inserted. Then the row of building plates 2 . 3 moved so far in the longitudinal direction L, that is a complete locking of the building panels 2 . 3 on the already laid building panels 32 or the series of already laid building panels 32 results.
  • Alternatively, it is possible to first the building panels 2 . 3 at their head sides in the manner described above with each other. Then the row of building plates 2 . 3 to the already laid row of building panels 32 pushed up until the state accordingly 2 results. Subsequently, a lateral displacement in the longitudinal direction L, so that there is a locking of the two rows of building panels 2 . 3 on the one hand and 32 on the other hand.
