Definitions

  • the invention relates to a panel, in particular a floor panel, comprising a body, complementary locking means which are provided in pairs on opposite panel edges so that several of these panels can be locked together, at least one pair of locking means with hook profiles, namely a receiving hook and a locking hook opposite this with the proviso that the receiving hook has a hook edge arranged farther from the fuselage and a receiving recess arranged closer to the fuselage, the receiving recess being open to the top, that the locking hook is provided with a locking recess arranged closer to the fuselage and open to the underside and having a locking shoulder arranged away from the fuselage, which is in the vertical joining direction fits into the receiving recess of the receiving hook, the locking hook having a fuselage-remote joint surface and likewise a vertically acting locking contour, the receiving hook being closer to the fuselage ne joint surface and also has a form-fitting contour closer to the fuselage, which fits together in a form-fitting manner with the locking contour of the locking hook remote from the fuselage
  • a panel for floors is known.
  • the hook profiles of the known panel are matched to the material from which the body of the panel is made.
  • Such panels can be hooked that have a body made of a flexible and elastic plastic material.
  • the locking contour which is provided below the joint surface of the locking hook, has areas which protrude from the plane of the joint surface and other areas set back from the plane of the joint face.
  • the form-fitting contour below the joint surface of the receiving hook has areas which protrude from the plane of the joint surface and other areas which recede from the plane of the joint surface.
  • the above-mentioned protruding and recessed areas of the form-fitting contour and the locking contour form undercuts, which counteract the two hook profiles moving apart in a direction perpendicular to the panel plane (vertical).
  • the locking contour and the form-fitting contour are pressed against and past one another. You have to be elastically deformed.
  • the locking contour and the form-fitting contour are flexible and can be brought into positive contact with one another in this way.
  • the maximum amount of undercut is limited due to the soft elastic property of the plastic material. The effect of the vertical locking is unsatisfactory.
  • Another panel with complementary locking means which have pairs of hook profiles, namely a receiving hook and a locking hook is in the US 6,591,568 B1 described.
  • the core of this panel consists of particles or fibers of wood bound with resin or glue.
  • the US 2010/0031594 A1 proposes a hardwood flooring system with a so-called push-down latch. It includes panels that have pairs of hook profiles designated as male and female locking mechanisms. A male locking mechanism of one panel can be inserted into the female locking mechanism of an adjacent panel by applying a downward force.
  • the female locking mechanism features a spring-loaded slot that promotes snapping.
  • a generic panel is from DE 10 2004 001 363 A1 known, this panel having a hull made of HDF / MDF or is designed as a parquet floor.
  • the object of the invention is to improve the panel in such a way that the variety of plastic materials that can be used for the hull is increased and the effect of the vertical locking is improved as much as possible.
  • the object is achieved in that the plastic layer of the fuselage is formed from an elastic plastic material such as a thermoplastic polymer, for example polyolefin, polypropylene, polyurethane or polyamide, or from soft PVC or from an amorphous elastomer such as PVC.
  • an elastic plastic material such as a thermoplastic polymer, for example polyolefin, polypropylene, polyurethane or polyamide, or from soft PVC or from an amorphous elastomer such as PVC.
  • the form-fitting contour can, for example, have a locking element that protrudes further than on the stand of the art, and the locking contour has a locking recess which is complementary to the locking element and which is deeper than in the prior art. Nevertheless, the locking contour and the form-fitting contour can be brought into engagement without any problems, because the bending web which is prepared for this purpose bends elastically and this bending enables the receiving opening to be widened. The locking contour and form-fitting contour can thus be moved past one another without any major deformation of their own until they engage.
  • the proposed soft PVC is a polyvinyl chloride that contains plasticizers. Basically, however, PVC is an amorphous elastomer with a natural hardness and brittleness that can only be reduced by plasticizers.
  • the panel is advantageously designed in such a way that it is also possible to produce the plastic layer of the core from a plastic material with natural hardness and brittleness, for example an amorphous elastomer such as PVC, which contains no or only a small amount of plasticizer.
  • a plastic material with natural hardness and brittleness for example an amorphous elastomer such as PVC, which contains no or only a small amount of plasticizer.
  • the thickness of the panels according to the invention is 3 to 10 mm, preferably 4 to 8 mm, particularly preferably 5 to 6 mm.
  • the area weight of the panels is between 1 and 2.5 kg/m 2 , preferably between 1.6 and 1.8 kg/m 2 .
  • a resilient snap-in tab can be provided on the hook edge of the receiving hook remote from the fuselage, with the locking recess having a snap-in recess near the fuselage, which fits together with the resilient snap-in tab.
  • a second point is created within the hook connection, which is formed by elastic deformation of an area provided and prepared for this purpose, namely the resilient locking tab. to be put together.
  • the spring-loaded snap-in tab also causes the two hook profiles to be locked in the vertical direction, ie perpendicular to the level of the locked panels.
  • the elastic properties of the torso can be utilized if the resilient locking tab is formed in one piece with the torso. If the body is made of a relatively hard plastic material, this favors, among other things, the production of the resilient latching tab by machining manufacturing processes such as milling.
  • the resilient locking tab is rooted on the side of the hooked edge that is remote from the hull, and the free end of the resilient locking tab projects obliquely from the hooked edge, for example obliquely downwards.
  • the resilient snap tab is always positioned such that contact with the complementary hook profile causes deflection of the integral snap tab, moving it closer to the body of its panel.
  • the resilient locking tab has a sliding surface. This comes into contact with the locking hook during a vertical joining movement. This contact moves the resilient locking tab closer to the hook edge of the receiving hook. In this way, it is stretched elastically and releases the joining path. The locking hook can then be inserted further into the receiving hook until both panels are level.
  • a free space can be provided between the resilient latching tab and the edge of the hook, into which the latching tab can deflect elastically.
  • the elastic preload allows the resilient locking tab to spring back toward its neutral position when space is available.
  • the latching recess expediently has a latching contact surface on. Through contact with the spring-loaded snap-in tab, this causes the connected panels to be locked in place in the vertical direction.
  • the locking contact surface is preferably designed in such a way that it forms a stop bevel for the free end of the resilient locking tab.
  • the stop bevel is designed in such a way that the tensioned locking tab, when it springs back towards its neutral position, hits this stop bevel. It can also be arranged in such a way that the locking tab hits before it reaches its neutral position, so that there is always a residual tension in the locking tab, which is used for secure locking.
  • the locking shoulder has an inclined sliding surface, which can be referred to as a sliding slope, on its side remote from the fuselage.
  • the sliding bevel is expediently designed in such a way that it interacts with that area of the form-fitting contour that protrudes.
  • This area of the form-fitting contour protruding from the joint plane forms, for example, a protruding latching element.
  • the protruding area interacts with the sliding slope of the locking heel. As soon as the sliding bevel comes into contact with the protruding area, for example the latching element, it slides along the latching element. As a result, the joint surfaces of the receiving hook and locking hook are initially moved apart.
  • the horizontal locking surface of the locking hook exerts a force pressing against the horizontal locking surface of the receiving hook.
  • This force introduced into the horizontal locking surface of the receiving hook is transmitted to the bending web of the receiving hook, which is elastically bent as a result.
  • the arresting contour passes the form-fitting contour until both have reached a position in which they form-fit into one another fit.
  • the bending stress in the bending web exerts a force via the horizontal locking surface of the receiving hook, which again prestresses the joint surface of the locking hook in the direction of the joint surface of the receiving hook. In this way a closed joint can be achieved.
  • the horizontal locking surfaces of the two hook profiles are then preferably nestled against one another.
  • the degree of bending of the flexible web can be influenced by the geometric shape of the sliding bevel (linear or curved). By varying the sliding bevel, the bending stress generated can be adjusted in such a way that the plastic material in the area of the bending bridge is not overloaded and is not damaged.
  • a pair of the complementary locking means is formed as pivot profiles.
  • a groove profile with an undercut on a groove wall and a tongue profile with an undercut on a tongue side are provided.
  • the hook profile of the new panel can be locked to the hook profile of a panel in the same row of panels at the same time.
  • the locking hook of the new panel is lowered in a scissors-like movement essentially in a vertical plane and inserted into the receiving hook.
  • the locking shoulder initially protrudes into the receiving opening only at one end of the panel edge.
  • the locking shoulder comes step by step into the receiving opening.
  • the resulting elastic deformation of the flexible web also increases step by step.
  • the panels are finally in one plane, the locking contour and the form-fitting contour are fitted exactly, the joint surfaces touch and form a closed joint.
  • the bending stress of the flexible web is eliminated again and the horizontal locking surfaces of the two hook profiles nestle flat against one another.
  • the area of application can be expanded if a decorative layer is provided on the upper side of the panel.
  • a further benefit results from the fact that a transparent cover layer is provided through which the cover layer is visible.
  • the transparent top layer serves to protect the decorative layer. It can be provided with means that reduce wear, for example corundum particles, glass particles, etc.
  • a counteracting layer is provided on the underside of the panel. This acts as a balance to the layers provided on the upper side to counteract warping of the panel.
  • FIGS 1a to 1d each show a detail of two panels 1 and 2, respectively.
  • the panels 1 and 2 are identical.
  • Each individual panel has complementary profiles 3 and 4 on opposite panel edges of a pair of edges. In panel 1, therefore, the edge, not shown, has identical profile 4 of panel 2, and in panel 2, the edge, not shown, has identical profile 3 of panel 1.
  • the second pair of edges may be formed with complementary profiles identical to the profiles of the first pair of edges.
  • each panel 1 and 2 respectively form complementary locking means V in the form of hook profiles H.
  • the hook profile of profile 1 forms a receiving hook 5 and the hook profile of profile 2 forms a locking hook 6 which fits into receiving hook 5, the both hook profiles are designed in such a way that locking occurs.
  • the locking counteracts a reversal of the joining movement.
  • the panels 1 and 2 can thus not be released from each other again in a backward movement after locking.
  • Each panel 1 or 2 comprises a body 1' or 2' with a plastic layer on which the complementary locking means V mentioned are arranged.
  • a top 7 of the panel forms a working surface.
  • a hook edge 8 is provided on the receiving hook 5 on the far side of the fuselage and a receiving recess 9 is provided closer to the fuselage.
  • the receiving recess 9 is open to the top 7 .
  • the locking hook 6 is provided with a locking recess 11 which is arranged closer to the fuselage and is open towards the underside 10 and has a locking heel 12 on the fuselage.
  • the locking heel fits into the receiving recess 9 of the receiving hook 5 in the vertical joining direction T.
  • the locking hook 6 has a joint surface 13 that is remote from the body and a locking contour 14 that has a vertical locking effect.
  • the receiving hook 5 has a joint surface close to the fuselage and also a form-fitting contour 16 close to the fuselage, which fits together in a form-fitting manner with the locking contour 14 of the locking hook 6 . In this way, vertical locking can be effected.
  • the locking hook 6 has a horizontal locking surface 17 arranged close to the fuselage, which is arranged on its locking shoulder 12 .
  • the receiving hook 5 has a horizontal locking surface 18 , which is arranged in the receiving recess 9 on the hull, which interacts with the horizontal locking surface 17 of the locking hook 6 .
  • the receiving hook 5 is provided with a narrowed receiving opening 19 in its receiving recess 9 .
  • the locking shoulder 12 can be inserted into the receiving recess 9 essentially in the vertical joining direction T, that is to say in a plane perpendicular to the plane of the locked panels.
  • the panel 1 with the receiving hook 5 is arranged on a solid surface (not shown).
  • the locking heel 12 of the panel 2 is lowered perpendicularly to the panel plane (vertical).
  • the rear locking contour 14 of the locking hook 5 has a latching recess 14a which projects behind the plane of the joint surface 13 of the locking hook 6.
  • the form-fitting contour 16 of the receiving hook 5 near the torso is designed in such a way that it has a latching element 16a which protrudes beyond the plane of the joint surface 15 of the receiving hook 5 and in the locked state engages/engages behind the latching recess 14a of the locking hook 6 .
  • the locking shoulder 12 and the receiving opening 19 are designed in such a way that the free heel end of the locking shoulder 12 initially fits into the receiving opening 19 during the beginning of the joining movement without any noticeable elastic deformation of the hook profiles.
  • the horizontal locking surface 17 of the locking hook 6 comes with part of its surface in contact with the horizontal locking surface 18 of the receiving hook 5.
  • a special bending web 20 is formed, which is best in the Figures 1b and 1c can be seen.
  • the flexible web 20 is designed in such a way that the width of the receiving opening 19 can be enlarged due to its elastic flexibility, so that the locking shoulder 12 can be inserted into the receiving recess 9 without any problems.
  • the locking contour 14 of the locking hook 6 can be inserted very easily into the form-fitting contour 16 of the receiving hook 5 due to the flexibility of the flexible web 20 .
  • the hook profiles are to be brought into engagement at the beginning of the joining path without already being elastically deformed at the point of engagement. Only as the joining movement progresses do the undercut areas of the locking contour 14 and the form-fitting contour 16 come into play at the engagement point Contact. However, this contact causes elastic deformation, which essentially takes place at a different point, namely at the bending web 20 provided for this purpose. Although the locking contour 14 and the form-fitting contour 16 are also pressed and deformed, the harder and more brittle the plastic material of the fuselage is, the lower the elastic deformation of locking contour 14 and form-fitting contour 16 and the higher the proportion of elastic deformation of bending web 20.
  • the locking recess 14a of the locking hook 6 is designed deeper than in the prior art.
  • the latching element 16a of the receiving hook 5 protrudes further from the joint surface 15 of the receiving hook 5 than in the prior art. This results in a higher degree of undercut in the vertical joining direction than in the prior art.
  • the locking contour 14 and form-fitting contour 16 can be brought into engagement without any problems. This is because the bending web 20 can be bent so elastically that this bending allows the receiving opening 19 to be widened. The locking contour 14 and form-fitting contour 16 can thus be moved past one another without any major deformation of their own until they are in a form-fitting engagement and develop their vertical locking effect.
  • Fig. 1b it is shown that an inclined surface is provided on the locking shoulder 12, which forms a sliding slope 12a.
  • the sliding bevel touches the protruding locking element 16a of the form-fitting contour 16 of the receiving hook.
  • a horizontal movement is superimposed, which moves the panels apart, so that a distance is formed between the joint surfaces 13, 15.
  • the horizontal locking surface 17 of the locking hook 6 exerts a force against the horizontal locking surface 18 of the receiving hook 5 presses.
  • the force acting on the horizontal locking surface 18 of the receiving hook 5 is transmitted to the bending web 20 of the receiving hook 5, which is elastically bent as a result.
  • the locking contour 14 and the form-fitting contour 16 have reached a position in which they fit into one another in a form-fitting manner.
  • the hook profiles H can be designed in such a way that a residual bending stress of the bending web 20 is retained and an elastic force (spring force) is exerted via the horizontal locking surface 18 of the receiving hook 5, which permanently moves the joint surface 13 of the locking hook 6 in the direction of the joint surface 15 of the receiving hook 5 biases. In this way, a closed joint can be achieved permanently.
  • the horizontal locking surfaces 17, 18 of the two hook profiles H nestle against one another and do not exert any permanent pretension.
  • FIGS. 2a to 2d each show sections of two panels 1 and 2, respectively. These are in turn identical.
  • Each individual panel has the complementary profiles shown on opposite panel edges of an edge pair.
  • the second pair of edges may be formed with complementary profiles identical to the panel edges of the first pair of edges.
  • a second positive lock is provided.
  • a resilient locking tab is provided, which is rooted in the hook edge 8 of the receiving hook 5 .
  • the locking recess 11 has a locking recess 22 close to the fuselage, which fits together with the resilient locking tab 21 .
  • a second point is created within a hook connection, which can be easily joined together by elastically deforming an area provided and prepared for this purpose, namely the resilient locking tab 21 .
  • the resilient latching tab 21, together with the locking recess 9, also causes the two hook profiles H to be locked in the vertical direction, ie perpendicular to the plane of the locked panels.
  • the resilient locking tab 21 is formed in one piece with the body. In this respect, the elastic properties of the hull are used. It is favorable for the locking effect of the resilient locking tab 21 if the plastic material of the body is relatively hard and rigid. A harder plastic material therefore works better than a soft plastic material that gives easily.
  • the resilient latching tab 21 protrudes from the edge of the hook 8 at an angle downwards. If the panel 1 lies with its underside 10 on a base (not shown), the free end of the resilient latching tab 21 points in the direction of the base.
  • the resilient locking tab 21 has rumpffern on a sliding surface 23 during the joining movement with the Locking hook 6 comes into contact and thus produces a spring deflection of the locking tab 21. As a result of the deflection, the locking tab 21 is moved closer to the hook edge 8 or closer to the body of the panel 1 .
  • the resilient latching tab 21 is stretched elastically and releases the vertical joining path so that the locking hook 6 can be lowered further. The locking hook 6 can then be inserted further into the receiving hook 5 until both panels 1 and 2 are in one plane.
  • the latching recess 22 has a latching contact surface 25 which, through contact with the resilient latching tab 21, causes connected panels to be locked vertically, that is to say perpendicularly to the panel plane.
  • the locking contact surface 25 is designed in such a way that it forms a stop bevel for the free end of the resilient locking tab 21 .
  • the abutment bevel 26 is designed in such a way that the tensioned, resilient locking tab 21, when it springs back towards its neutral position, abuts this abutment bevel 26 before it reaches its neutral position. In this way, a residual pretension is always retained in the latching tab 21, which ensures secure locking.
