Panel and covering formed with such panels

Abstract

A panel includes a top side, a bottom side and a first edge extending between the top and bottom side and having a first coupling part; and a second edge extending between the top and bottom side and having a second coupling part. The coupling parts make it possible to produce a horizontal and vertical lock between two such panels by means of a vertical movement of the one panel with respect to the other panel.

         27 . A panel, comprising a top side, a bottom side and a first edge extending between the top and bottom side and having a first coupling part, and a second edge extending between the top and bottom side and having a second coupling part, which coupling parts make it possible to produce a horizontal and vertical lock between two such panels by means of a vertical movement of the one panel with respect to the other panel,
 wherein the first coupling part comprises a lip which is situated on the bottom side of the panel and has a first, upwardly directed locking element which forms a first locking surface, which first locking surface, in the coupled position, cooperates with a second locking surface which is formed in a first, downwardly directed locking groove of the second coupling part, in order to partly or completely produce the horizontal lock,   wherein the coupling parts comprise a second, separate locking element which, in the coupled position, cooperates with a second locking groove of the coupling parts in order to partly or completely produce the vertical lock and   wherein the first coupling part comprises a first closure surface which, in the coupled position, cooperates with a second closure surface of the second coupling part, in this case defining a vertical closure face,   wherein the separate locking element is part of the first coupling part,   wherein the lip is elastically bent in the coupled position, in such a way that a reactive force is generated which pushes the coupled panels against each other at the location of the cooperating closure surfaces, and   wherein the upwardly directed locking element, viewed in the disengaged position, has an uppermost point which is situated at a vertical distance from the bottom side of the panel of at least 0.35 times the thickness of the panel.   
     
     
         28 . The panel of  claim 27 , wherein, in the coupled position, the cooperating locking surfaces define a central point which is situated at a horizontal distance from the vertical closure face which is at most once the thickness of the panel. 
     
     
         29 . The panel of  claim 27 , wherein, in the coupled position, the cooperating locking surfaces define a tangent which forms an angle with the horizontal from 45 to 85 degrees, but less than 90 degrees. 
     
     
         30 . The panel of  claim 27 , wherein, viewed in the disengaged position, the lip has a most distal point which is situated at a horizontal distance from the vertical closure face which is at least once the thickness of the panel. 
     
     
         31 . The panel of  claim 27 , wherein the lip is bent over a maximum vertical distance of 0.0025 to 0.015 times the thickness of the panel. 
     
     
         32 . The panel of  claim 27 , wherein the upwardly directed locking element is connected to another portion of the lip via a stepped portion of a top side of the lip, which stepped portion runs upwards in the direction towards the upwardly directed locking element. 
     
     
         33 . The panel of  claim 27 , wherein the lip has a minimum thickness which is at least 0.175 times the thickness of the panel. 
     
     
         34 . The panel of  claim 27 , wherein the downwardly directed locking groove has a bottom which runs substantially obliquely downwards in a direction away from the second locking surface. 
     
     
         35 . The panel of  claim 27 , wherein the first and second coupling part are configured in such a way that they make it possible to disengage the respective edges by means of a turning movement. 
     
     
         36 . The panel of  claim 27 , wherein the panel comprises a core or core layer made of wood or wood-based material, such as MDF or HDF, and
 wherein the first and/or second coupling part is at least partly made of this wood or wood-based material.   
     
     
         37 . The panel of  claim 27 , wherein the thickness of the panel ranges from 3 to 20 millimeters. 
     
     
         38 . The panel of  claim 27 , wherein the top side of the panel is free from chamfers or bevels on the first and/or second edge. 
     
     
         39 . The panel of  claim 27 , wherein the panel is rectangular and the first and second edges form the short edges of the panel. 
     
     
         40 . The panel of  claim 39 , wherein the panel comprises coupling parts on the long edges, which coupling parts make it possible to produce a horizontal and vertical lock between two such panels by means of a turning movement of the one panel with respect to the other panel. 
     
     
         41 . A panel, comprising a top side, a bottom side and a first edge extending between the top and bottom side and having a first coupling part, and a second edge extending between the top and bottom side and having a second coupling part, which coupling parts make it possible to produce a horizontal and vertical lock between two such panels by means of a vertical movement of the one panel with respect to the other panel,
 wherein the first coupling part comprises a lip which is situated on the bottom side of the panel and has a first, upwardly directed locking element which forms a first locking surface, which first locking surface, in the coupled position, cooperates with a second locking surface which is formed in a first, downwardly directed locking groove of the second coupling part, in order to partly or completely produce the horizontal lock,   wherein the coupling parts comprise a second, separate locking element which, in the coupled position, cooperates with a second locking groove of the coupling parts in order to partly or completely produce the vertical lock and   wherein the first coupling part comprises a first closure surface which, in the coupled position, cooperates with a second closure surface of the second coupling part, in this case defining a vertical closure face,   wherein the separate locking element is part of the first coupling part,   wherein the lip is elastically bent in the coupled position, in such a way that a reactive force is generated which pushes the coupled panels against each other at the location of the cooperating closure surfaces, and   wherein the upwardly directed locking element, viewed in the disengaged and/or coupled position, has an uppermost point which defines a horizontal level, which horizontal level is situated above at least a portion of the separate locking element.
