Abstract

The invention relates to a panel and an interlocking system (1) for panels (2, 3) comprising edge profiles which are arranged on at least two opposite edges of the panels (2, 3) and are used to positively engage similar panels (2, 3). Said interlocking system comprises an edge profile which is embodied as a groove profile (4) and comprises an upper groove wall (6), a lower groove wall (7) and an edge profile which is embodied as a spring profile (5) and is provided with a catch projection (12) which is arranged on the lower side of the spring and, in the connected state, engages with the rear of a catch recess (11) in the lower groove wall (7) of an adjacent panel. Said rear-engaging edge profiles form a joint (G) which, both in the upwardly deviated state and the downwardly deviated state of the connection, causes a restoring action of the panels (2, 3) in the installation plane thereof. The upper groove wall (6) comprises a free surface (21) on the inner side thereof, which opens towards the free end of the groove wall (6).

Description

  • The invention relates to a panel and a locking system for panels with at least two opposite edges of the panels arranged edge profiles for positive connection similar panels, comprising an edge profile formed as a groove profile with an upper groove wall with a butting surface and a lower groove wall and a spring profile formed as an edge profile with an abutment surface and a detent projection arranged on a spring underside, which engages in the joined state a detent recess in the lower groove wall of a neighboring panel, the final position of the panels in the direction of the joining process being determined solely by contacting the abutment surface of the spring profile with the abutment surface of the groove profile, wherein the engaging behind edge profiles form a joint, which effect a return effect of the panels in the laying plane both in the upwardly and downwardly deflected state of the compound t, and wherein the panels are lockable by obliquely applying the edge profile of a new panel to the edge profile of a lying panel and then folding down the new panel in the laying plane.
  • Such locking systems are used for example for floor panels, such as parquet panels with real wood surface or laminate panels. The latter are made of a core of MDF, HDF or chipboard and provided with a reproduced surface of an art decor.
  • From the 299 11 462 U1 a generic locking system is known, the compound has a joint function. Such locking systems will be used for floor coverings that are, for example, on uneven surfaces or have to endure a deflection in the connection area because of a soft surface, such as a footfall sound insulation. A deflection of the connection causes a high stress in the region of the tongue and groove profiles of two locked panels, because the compound curves under load. The material of the panels does not tolerate the high stresses in the area of the edge profiles and fails in the connection area.
  • The ease of installation of the known articulated locking system leaves much to be desired. Its resistance to being pulled apart at the laying level does not meet future expected quality standards for floors with mechanical locking system. Furthermore, the known articulated connection can be laid in two ways, wherein the laying method described as the second entails the undesirable side effect that the connection has a particularly low resistance to pulling apart.
  • After the first type of laying a new panel is preferably attached to the spring obliquely to a lying panel and then folded down or turned down until it lies in the common installation plane of the panels and automatically locked.
  • In the second type of installation, the locking takes place while both panels are in the laying plane, namely by lateral displacement of the panels toward each other. The panels can be locked in this way only because of the degree of Undercut between the latching projection of the spring and the latching recess of the lower groove wall is formed correspondingly small. The catch which can be produced in this way has a strength which is so low that gaps can form on the abutment surfaces of adjacent panels due to the usual change in length of the floor. This is the case, for example, with temperature fluctuations in the floor. In addition, occurs in this type of joining a pre-damage of the edge profiles, because they must be subjected to a strong deformation in order to cause a Hintergreif the undercut of spring and lower groove wall.
  • Furthermore, the spring of the known locking system has a long pointed shape. At the top of the spring an inclined surface is arranged to facilitate the threading of the spring tip into the groove. With manual handling, the spring proves to be very vulnerable because of their pointed shape. This is detrimental to ease of installation, durability and serviceability of the product.
  • The invention has for its object to provide a locking system for an articulated panel connection, which has a better stability than the known locking system.
  • According to the invention the object is achieved in that the upper groove wall has on the inside a free surface which opens to the free end of the groove wall, and that the spring profile has at its free end a blunt surface adjacent to a leveling surface of a spring top of the spring profile.
  • By providing a free surface on the upper groove wall is formed on the Nutprofilseite a panel a wide groove opening in which the spring profile of a neighboring panel can be better inserted than the known pointed spring profile in the narrower slot opening of the known locking system.
  • Preferably, a leveling surface extending to the groove bottom is connected to the free surface, via which an exact height alignment without height offset between locked panels is brought about. In other words, the running from the free surface to the groove bottom piece of the inside of the upper groove wall forms the leveling surface whose distance to the surface of the panel with the distance measure of the spring top to the surface of the panel exactly matches, so that no height offset occurs between locked panels.
  • The free surface may have a curved or a flat course, with a straight course is favorable production technology and a curved course is still a little gentler for the joining process of the panels. When coming into contact of the spring profile with the curved free surface of the groove profile, the surface pressure is slightly lower than when a contact of the spring profile with the edge at the end of the flat free surface.
  • On the upper side of the spring said leveling surface is provided, which cooperates in the joined state of the panels with the leveling surface of the upper groove wall. Since the upper groove wall at the front free end has a free surface, the leveling surface of the spring is only partially in contact with the leveling surface of the upper groove wall, namely in the region of the free end of the spring. If the leveling surface of the spring were in contact with the upper groove wall along the entire length of the spring surface, a rigid connection would result. The open space gives the connection a compliance that favors the joint function of the connection and reduces the stresses in the material of the edge profiles.
  • In particular, for a deflection of the connection to the laying surface out a free space is created by the free space, so that the spring top can be moved to the open space without early on this abut. The flexibility of the connection thus created allows the joint movement without causing a break in the spring or damaging the groove walls due to excessive stresses.
  • The handling and durability of the locking system is improved when the spring dimension by which the spring protrudes beyond the upper edge of the panel is less than or equal to the thickness of the upper groove wall of the groove profile. A spring with these dimensions is a short spring compared to the prior art. The short spring has the advantage that when obliquely inserted into a groove profile, a relatively short Einfädelweg the spring must be covered. The proposed locking system is therefore particularly easy to handle easy to handle and can be laid much faster than the known locking system.
  • The spring has at its free end a blunt surface which is more robust and durable compared to the pointed shape of the spring of the known locking system.
  • Conveniently, the groove depth of the groove profile, around which the groove projects behind the upper edge of the panel formed about half deeper than the spring size described above. In other words, if starting from the top of the panel, the groove depth is 3/3, the spring protrudes in the assembled state of two panels by a spring dimension of 2/3 into the groove, so that between the free end of the spring and the groove bottom Free space exists, which has approximately a residual depth of 1/3 of the groove depth. For mere reception of the spring in the groove such a large groove depth would not be required. However, the large groove depth affects the resilient length of the free from the edge of a panel protruding bottom groove wall. This makes the connection yieldingly reduces the stresses in the material and therefore increases the durability of the connection.
  • Preferably, the resilient length of the lower groove wall corresponds to almost the thickness of the panel. This is because then the required at the free end of the lower groove wall travel relative to the Length of the spring is relatively small and the elastic expansion caused when joining the panels only low stresses in the material, which are easily tolerated.
  • Conveniently, the depth of the recess in the lower groove wall is about one third of the thickness of the spring. Thus, a degree of undercut is achieved in the assembled state, which prevents a pulling apart of the panels in the installed state under normal conditions of use. In comparison to conventional mechanical locking systems according to the prior art, which can be locked by plan moving in the laying plane, the degree of undercut of the locking system according to the invention has been approximately doubled and, consequently, the strength against pulling in the laying plane befindlicher panels dramatically increased.
  • For material-saving production, the blending dimensions at the edges of the panels are relatively low. They are preferably different on the Nutprofilseite and on the spring profile side.
  • On the Nutprofilseite a panel is conveniently obtained for the decorated top a Verschnittmaß that is smaller than half the panel thickness.
  • On the spring profile side of a panel results for the decorated top a preferred Verschnittmaß, which is approximately between 1/3 and 1/4 of the thickness of the panel. It substantially corresponds to the extent to which the spring protrudes from the upper edge of the panel.
  • Conveniently, a panel, in particular floor panel is equipped with a locking system according to the invention. The locking profile is preferably used for laminate floor panels consisting of a core material of HDF, MDF or chipboard, wherein the edge profiles of the locking system are milled on the edges of the panels.
  • The invention is illustrated by way of example in a drawing and described in detail with reference to FIGS. Show it:
  • Fig. 1:
    A locking system based on a spring profile and a groove profile of two assembled panels,
    Fig. 2:
    The locking system according to FIG. 1 during the joining,
    3:
    The locking system according to Figure 1, wherein the hinge connection is lifted from the ground and deflected upwards,
    4:
    Is an illustration of the locking system according to Figure 1 in a downwardly deflected down to the laying surface connection.
  • After the drawing, the locking system 1 consists of two positive interlocking edge profiles, which are arranged at the edges of a panel 2 and 3, respectively. The edge profiles are largely complementary to one another as a groove profile 4 and spring profile 5 is formed. The groove profile 4 at one edge of a panel 2 or 3 is always a spring profile 5 at the opposite edge of the same panel 2 or 3 opposite. In this way, similarly profiled panels 2 and 3 can be connected to each other. Conveniently, the locking system 1 is provided on all opposite sides of a panel 2 or 3.
  • The described embodiment relates to floor panels which are provided with the locking system according to the invention. The locking system can of course be used, for example, also for wall and ceiling trim panels or panels for fence or house construction, in which the problem of deflection appears to a lesser extent.
  • It can be seen in FIG. 1 that the locking system according to the invention is a modified tongue and groove profile. The groove walls 6 and 7 of the groove profile 4 project different from the edge of the panel 3. For the areas 8 and 9 in addition to the spring 10 of the spring profile 5, that they are different far from the edge of the panel 2. Spring profile 5 and groove profile 4 are so adapted to each other with their aforementioned protruding groove walls 6 and 7 or the recessed areas 8 and 9, that an assembly is possible. In order to secure the locking against planar pulling apart of the panels 2 and 3 in the laying plane, a concave recess 11 is incorporated in the inside of the lower groove wall 7, which is engaged behind by a convex locking projection 12 in the assembled state shown in FIG. The convex latching projection 12 is arranged on the underside of the spring 10 facing the laying substrate U. At the free protruding end of the lower groove wall 7, a skirt 13 forms a resistance to the flat pulling out of the spring 10 of the panel 2 from the groove profile 4 of the neighboring panel. 3
  • It can also be seen in FIG. 1 that the edges of the edge profiles are in contact with each other only at three areas. To mention first is the laying surface U facing away from the upper edge of the two panels 2 and 3, where there is a closed gap-free joint. Shock surfaces 14 and 15 are in contact here. The second contact point is the contact point between the upper side of the spring and the inner side of the upper groove wall. Here are leveling surfaces 16 and 17 of the two edge profiles in contact with each other, wherein both the leveling surface 16 of the spring 10 and the leveling surface 17 of the upper groove wall 6 exactly the same distance to the top of the respective panel 2 and 3 respectively. In this way, a height offset between the joined panels 2 and 3 is avoided. The third point of contact is the contact between the concave recess 11 of the lower groove wall 7 and the convex locking projection 12 of the spring 10. This contact point is located on the free end of the lower groove wall 7 facing part of the recess 11. Between these contact points are generous free spaces 18, 19 and Provided 20 so that a contact actually always takes place only at the desired contact points and a gap-free closed joint is ensured at the top of a floor covering and no height offset comes about.
  • In the present embodiment, a flat free surface 21 is provided on the inside of the upper groove wall 6, whereby the spring top only serves as a leveling surface 16 in the region of its free end, which is in contact with the leveling surface 17 of the upper groove wall 6. According to FIG. 1, a spring dimension f is shown by which the spring 10 projects beyond the upper edge of the panel 2. This spring dimension f is less than or equal to the thickness n of the upper groove wall 6. This is a relatively low cantilevered spring 10. Due to the inclined free surface 21 on the upper groove wall 6 a wide mouth-like opening 22 is formed, in which the short Feather 10 is very easy to insert. Because of the shortness of the spring 10 also results in a very short Einfädelweg until the spring 10 is completely inserted into the groove. The joining of panels, which are equipped with this locking system, is very simple and much faster to carry out by hand than with panels having the known locking system.
  • The groove depth t, by which the groove projects behind the upper edge of the panel 3, is formed deeper by about half than the spring dimension f. Such a groove depth t would not be necessary for receiving the spring 10. However, it favors the resilience of the groove walls 6 and 7, in particular the lower groove wall 7, which must be expanded resiliently to join the panels 2 and 3 by a small amount. By the spring elasticity of the material results in a reset effect. The panels 2 and 3 spring back into the zero position shown in FIG. 1, in which both panels are in a common plane. The resulting space 19 also serves to receive dirt particles that may get into the connection during installation of the panels 2 and 3. In addition, the compound can be improved by the addition of adhesive in the space 19, but depending on the choice of the adhesive, a change in the joint properties of the compound occurs.
  • FIG. 2 shows the application of a panel 2 with the spring profile 5 to the groove profile 4 of a panel 3 already located on the laying substrate U.
  • In the groove profile 4 of the lying panel 3 with the wide mouth-like opening 22 formed by the open space, the blunt free end 23 of the spring 10 can be inserted very obliquely on a short threading path. In the position shown in Figure 2 at the beginning of the joining movement, there are three touch points. A second edge contact 25 results at the top of the spring with the upper groove wall 6 and a third contact 26 on the convex locking projection 12 of the spring 10 and the concave recess 11 of the lower Groove wall 7. From the position shown in Fig. 2, a minimal expansion, essentially by Wegfedern of the lower groove wall 7 to the laying surface U out by continuation of the joining operation. In this way, the convex locking projection 12 of the spring 10 is moved into the recess 11 of the lower groove wall 7 and reaches the final position of the panels 2 and 3, as shown in Fig. 1. In this position, the latching projection 12 of the spring 10 engages behind the edge strip of the lower groove wall 7 and ensures a firm hold against plan pulling apart.
  • In Figures 3 and 4, the locking system 1 is shown so that the joint function of the compound is recognizable.
  • The locking system 1 is used for floor coverings which rest for example on uneven laying grounds U. In such uneven installation substrates U, it may happen that the panels 2 and 3 in the region of a connection point have no contact with the ground but air is present. At ballast in the area of the connection this bends. Therefore, a deflection of the edge profiles must be tolerated in the connection area. A curvature of the connection can also occur on a level surface U underground. This is when the panels 2 and 3 are laid on a soft base, for example a footfall sound insulation.
  • To withstand such loads, constructive measures are provided which give the connection the necessary articulation. The compliance prevents a deflection of the connection causing such high stresses in the region of the groove profile 4 and of the spring profile 5 that the material of the panels 2 and 3 fails under the high stresses. The positions shown in FIGS. 3 and 4 are arbitrary positions for the movement. These are not end positions for joint movement.
  • FIG. 3 shows the connection in a deflection state moving upwards, ie away from the laying substrate U. In this position, in turn, a small elastic deflection is substantially present on the lower groove wall 7. Due to its resilience, the lower groove wall 7 exerts a restoring action on the panels 2 and 3, as soon as the load is withdrawn. Due to the joint movement, the free space 20 between the root of the spring 10 and the edge strip 13 of the lower groove wall 7 has been reduced. The existing clearance 20 in this way allows the articulated compliance of the connection. The free space 18, however, increases.
  • FIG. 4 shows a deflection of the locking system in the opposite direction, towards the laying substrate U. Here, too, is a resilient expansion substantially to note the lower groove wall 7, which likewise exerts a restoring action on the panels 2 and 3 upon withdrawal of the ballast. Due to the joint movement of the free space 18 between the spring 10 and the free surface 21 of the upper groove wall 6 has now reduced. In this case, the clearance 18 allows the articulated compliance of the connection. The free space 20, however, increases.
