Method for making rigid structures from panels

Abstract

The invention concerns a method for making a three-dimensional rigid structure by wedging from at least an initial flat panel. A drill runs along and cuts the panel producing one or more rectangular recesses to obtain ladder-type frames provided with cut-out edges and side panels provided with notches. The notches and cut-out edges with rounded bases are designed to co-operate and enable a side panel to be wedged between two parallel ladder-type frames provided with a floor panel, the latter being obtained separately. The floor panel is provided with four notches designed to be wedged in the edge of four vertical posts of two ladder-type frames arranged parallel.

1 : A method for making a three-dimensional rigid structure from at least one original flat panel, characterized in that a drill runs along and cuts the panel while forming one or more rectangular recesses to obtain a ladder-type frame having trimmed portions and side panels having notches, said notches and trimmed portions being provided to allow a side panel to be wedged between two parallel ladder-type frames with a floor panel fitted thereon, the latter being obtained separately.  
   
   
       2 : A method as claimed in  claim 1 , wherein the notches and trimmed portions are provided to cooperate during wedging.  
   
   
       3 : A method as claimed in  claim 1  or  2 , wherein trimmed portions are provided at the upper corners of each recess of the ladder-type frame.  
   
   
       4 : A method as claimed in  claim 1 , wherein the trimmed portions are formed in the corresponding rung, parallel to the uprights.  
   
   
       5 : A method as claimed in  claim 1 , including the provision of a floor panel having four notches adapted to be wedged in the edges of the four uprights of two parallel ladder-type frames.  
   
   
       6 : A method as claimed in  claim 1 , wherein the floor panels are obtained by being cut out from a larger original panel with the help of a saw.  
   
   
       7 : A method as claimed in  claim 5  or  6  wherein the notches are obtained by using a drill.  
   
   
       8 : A method as claimed in  claim 1 , wherein the drill forms a trimmed portion in the uprights at each lower corner of the recesses, the trimmed portions so obtained being adapted for cooperating with the notches of the floor panel.  
   
   
       9 : A three-dimensional structure comprising at least two ladder-type frames having trimmed portions and side panels having notches, said notches and trimmed portions having round bottoms and cooperating by wedging a side panel between two parallel ladder-type frames with one floor panel fitted thereon.  
   
   
       10 : A structure as claimed in  claim 9 , wherein the floor panel has at least four notches which are adapted to hold the edge of an upright.  
   
   
       11 : A structure as claimed in  claim 9  or  10  wherein the notches have rounded bottoms.  
   
   
       12 : A structure as claimed in  claim 9 , wherein the trimmed portions in the uprights are formed at each lower corner of the recesses, the trimmed portions so obtained being adapted for cooperating with the floor panel.  
   
   
       13 : A structure as claim in  claim 9 , wherein the side panels are wedged against the uprights of the ladder-type frames.  
   
   
       14 : A piece of furniture comprising a structure as claimed in  claim 9 .  
   
   
       15 : A shelf comprising or formed by a structure as claimed in  claim 9 .  
   
   
       16 : An assembly of combined elements, adapted to be assembled to form a structure or a shelf as claimed in  claim 9.
