Method for the production of a furniture body

Abstract

In a method to produce a furniture body, a V-shaped groove is cut into a board of wood or similar material that includes a veneer on its outer surface from its inner side along each of several straight lines in the area of the body corner edge to be formed to a depth meeting the veneer. Subsequently, the body sides separated from each other are pivoted together by closing the V-shaped groove that forms the miter faces on which adhesive was placed, whereby the veneer layer is deformed or broken along the edge that is formed. For the purpose of producing a pivoting hinge, a smaller starter groove is cut to a depth up to the veneer layer at each location before the V-shaped groove is produced. This smaller starter groove possesses a groove base with a final width that extends to both sides over the face area of the V-shaped groove to be produced subsequently. A fluid adhesive is injected into the starter groove where it hardens, filling the starter groove at least partially from the veneer layer and binding with the material of the board and of the veneer layer. Subsequently, each V-shaped groove is cut through the board material and through the hardened plastic material so that an elastic, film-like spar of the plastic material remains between the face area of the V-shaped groove and the veneer layer.

1 . Method to produce a furniture body with body sides ( 10 ) of wood or similar material joined together at common edges by means of miter faces, in which a V-shaped groove ( 7 ) is cut into a board ( 1 ) of wood or similar material that includes a veneer layer ( 3 ) of plastic or a veneer on the side of the finished body facing the outer side ( 2 ), from its inner side ( 4 ) along each of several straight lines in the area of the body corner edge to be formed to a depth meeting the veneer layer ( 3 ), after which the body sides ( 10 ) thus separated from one another are pivoted together by closing the V-shaped groove ( 7 ) forming the miter faces with their flanks ( 8 ) into which a plastic has been introduced, whereby the veneer layer ( 3 ) is deformed or broken along the edges thus formed, 
 characterized in that    before cutting the V-shaped groove ( 7 ), a starter groove ( 5 ) with smaller cross section is cut through to the veneer layer ( 3 ) at the same location that possesses a groove base ( 15 ) with a final width that extends to both sides over the face area of the V-shaped groove ( 7 ) to be produced subsequently, and that a fluid plastic material ( 6 ) is introduced into the starter groove ( 5 ) where it hardens and remains partially elastic at least near the areas of small cross section, filling the starter groove ( 5 ) at least partially from the veneer layer ( 3 ) and binding with the material of the board ( 1 ) and of the veneer layer ( 3 ), after which each V-shaped groove ( 7 ) is cut through the board material and through the hardened plastic material ( 6 ) so that an elastic, film-like spar ( 9 ) of the plastic material ( 6 ) remains between the face area of the V-shaped groove ( 5 ) and the veneer layer ( 3 ).    
   
   
       2 . Method as in  claim 1 , characterized in that the starter groove ( 5 ) is formed at least in the area of its groove base ( 15 ) with a rectangular or square cross-sectional shape to be symmetrical to the oblique plane perpendicular to the board plane through the line along which the V-shaped groove ( 7 ) will subsequently be cut.  
   
   
       3 . Method as in  claim 1  or  2 , characterized in that laminated plywood material is used as the board material.  
   
   
       4 . Method as in one of claims  1 - 3 , characterized in that polyurethane plastic with thermoplastic properties is used as the plastic material ( 6 ).  
   
   
       5 . Method as in one of claims  1 - 4 , characterized in that the plastic material ( 6 ) is injected into the starter groove ( 5 ) under pressure.  
   
   
       6 . Method as in one of claims  1 - 5 , characterized in that the V-shaped groove ( 7 ) is cut with a flattening ( 16 ) in the face area, whereby the width of this flattening ( 16 ) is less than the width of the starter groove ( 5 ) at its groove base ( 15 ).  
   
   
       7 . Method as in one of claims  1 - 6 , characterized in that the veneer layer ( 3 ) on the side opposite the V-shaped groove ( 7 ) is cut in or cut through along the face line of the V-shaped groove ( 7 ) before the body sides ( 10 ) are pivoted together.  
   
   
       8 . Method as in one of claims  1 - 7 , characterized in that the cut or break lines of the veneer layer ( 3 ) are cut or ground along the body edges for the purpose of mounting a smooth chamfer ( 14 ) after the body sides ( 10 ) are pivoted together.  
   
   
       9 . Method as in  claim 8 , characterized in that the plastic material ( 6 ) is etched at the cut or break edge of the veneer layer ( 3 ) near the folded spar ( 9 ) when the chamfer ( 14 ) is cut.
