Joint for a Panel

Abstract

A joint for a panel, the joint comprising a first edge and a second edge. The first edge comprises a groove while the second edge is provided with a tongue. The second edge further comprises an upper side groove. A joining profile is provided with a tongue and an intermediate section, the joining profile being so configured so as to allowing it to be located in the upper portion of the joint between two, joined, adjacent panels.

1 . A joint for a panel, the joint comprising a first edge and a second edge whereby the first edge comprises a groove and the second edge is provided with a tongue wherein the second edge further comprises an upper side groove, that a joining profile is provided with a tongue and an intermediate section, the joining profile being so configured so as to allowing it to be located in the upper portion of the joint between two, joined, adjacent panels.  
   
   
       2 . A joint for a panel according to  claim 1 , the joint comprising a first edge and a second edge whereby the first edge comprises a groove and the second edge is provided with a tongue wherein the first edge further comprises an upper side groove and the second edge comprises an upper side groove, that a joining profile is provided with a first and second snapping tongue and an intermediate section, the joining profile being so configured so as to allowing the first and second snapping tongue to be fitted into upper side grooves of two, joined, adjacent panels.  
   
   
       3 . A joint according to  claim 2  wherein the joint further comprises mating surfaces, that the joining profile and the upper side grooves are so configured that a play is created in the joint between the mating surfaces.  
   
   
       4 . A joint according to  claim 3  wherein the play is in the range 0.05-1 mm.  
   
   
       5 . A joint according to  claim 1  wherein the tongue and the groove are configured to limit the movement in a vertical direction between two adjacent panels.  
   
   
       6 . A joint according to  claim 2  wherein the joining profile and the upper side grooves are configured to limit the movement in horizontal direction between two adjacent panels.  
   
   
       7 . A joint according to  claim 2  wherein a portion arranged between the upper side groove and its respective distal edge portion comprises a recess.  
   
   
       8 . A joint according to  claim 7  wherein the recess further comprises one or more supporting protrusions, the supporting protrusions supporting a lower side of the intermediate section of the joining profile.  
   
   
       9 . A joint according to  claim 2  wherein the upper side groove is provided with a first groove edge surface having an angle α of 1-50° towards a vertical plane.  
   
   
       10 . A joint according to  claim 2  wherein the first groove edge surface will create a pressure on an outer edge of the joining profile when two adjacent panels are forced together, the pressure causing the intermediate section to be urged downwards.  
   
   
       11 . A joint according to  claim 10  wherein a portion arranged between the upper side groove and is respective distal edge portion comprises a recess, the recess being adapted to receive the lower portion of the intermediate section when being urged downwards.  
   
   
       12 . A joint according to  claim 2  wherein the upper side groove is provided with a first groove edge surface and a second groove edge surface between the first and second groove edge surfaces a predetermined distance is present, the distance being so configured that the snapping tongue may be pressed in between the first and second groove edge surfaces.  
   
   
       13 . A joint according to  claim 12  wherein the first and second groove edge surfaces are arranged so that an undercut is present, that the snapping tongue of the joining profile is adapted to the undercut so that a snap action locking effect is achieved.  
   
   
       14 . A joint according to  claim 2  wherein the tongue is provided with at least one protrusion and that the groove is provided with recesses arranged to mate with the at least one protrusion, that the at least one protrusion with matching recess is configured to allow a predetermined movement in the horizontal plane.  
   
   
       15 . A joint according to  claim 14  wherein the predetermined movement is in the range 0.05 mm-1 mm.  
   
   
       16 . A joint according to  claim 2  wherein the joining profile is provided with at least one compression zone.
