Panel joint

Abstract

A panel joint for positioning and holding panels together via their respective edges in order to form a surface comprising a plurality of said panels assembled together. The edges of said panels are provided with a core and means for mechanically locking said panels towards one another via interacting locking surfaces. The edges further comprises friction enhancing means intended for impeding assembled panels from sliding in a direction along the edges.

We claim:  
     
         1 . A panel joint for positioning and holding panels together via their respective edges in order to form a surface comprising a plurality of said panels assembled together wherein the edges of said panels are provided with a core and means for mechanically locking said panels towards one another via interacting locking surfaces, said edges further comprising friction enhancing means intended for impeding assembled panels from sliding in a direction along the edges.  
     
     
         2 . A panel joint according to  claim 1  wherein the force needed to overcome the static friction along the joint between two assembled panels is larger than 100 N per meter of joint length, preferably larger than 1000 N per meter of joint length.  
     
     
         3 . A panel joint according to  claim 2  wherein predetermined surfaces of the edge are provided with a rough surface.  
     
     
         4 . A panel joint according to  claim 3  wherein the core of the panels is made of a wood based material and that the rough surface is achieved by wetting the predetermined surfaces of the edge with a liquid hereby causing fibre of the core to rise.  
     
     
         5 . A panel joint according to  claim 4  wherein the liquid comprises a binding agent.  
     
     
         6 . A panel joint according to  claim 5  wherein the liquid binding agent is a lacquer.  
     
     
         7 . A panel joint according to  claim 2  wherein predetermined surfaces of the edge is coated with a high friction polymer.  
     
     
         8 . A panel joint according to  claim 7  wherein the high friction polymer is a natural rubber.  
     
     
         9 . A panel joint according to  claim 7  wherein the high friction polymer is a synthetic rubber.  
     
     
         10 . A panel joint according to  claim 9  wherein the synthetic rubber is a silicon rubber.  
     
     
         11 . A panel joint according to  claim 3  wherein the rough surface is comprised by particles bonded to the predetermined surfaces of the edges.  
     
     
         12 . A panel joint according to  claim 11  wherein the particles have a size in the range 50 μm to 2 mm.  
     
     
         13 . A panel joint according to  claim 12  wherein the particles have a higher hardness index than the material of the core.  
     
     
         14 . A panel joint according to  claim 3  wherein the predetermined surfaces of the edges is provided with splines.  
     
     
         15 . A panel joint according to  claim 14  wherein the splines are arranged at an angle towards the extension of the edge of the panel.  
     
     
         16 . A panel joint according to  claim 2  wherein a jagged profile is arranged between predetermined surfaces of the edges.
