Elementary furniture module and stack of such furniture

Abstract

The module comprises at least two front and rear chassis-frames, each with two right and left uprights and two top and bottom crosspieces, two right and left side walls inside the frames and a floor inside the frames bearing against the bottom crosspieces of the frames. The floor is arranged to oppose the movement of the bottom portions of the side walls towards each other. The uprights of the frames are arranged to oppose the movement of the side walls away from each other. The top portions of the side walls and the top crosspieces of the frames are arranged to oppose the movement of the side walls towards each other.

1 . An elementary furniture module comprising at least two front and rear chassis-frames, each with two right and left uprights and two top and bottom crosspieces, two right and left side walls inside the frames and a floor inside the frames bearing against the bottom crosspieces of the frames, wherein the floor is arranged to oppose the movement of the bottom portions of the side walls towards each other. 
     
     
         2 . The elementary module according to  claim 1 , wherein the uprights of the frames are arranged to oppose the movement of the side walls away from each other. 
     
     
         3 . The elementary module according to  claim 1 , wherein the top portions of the side walls and the top crosspieces of the frames are arranged to oppose the movement of those towards each other. 
     
     
         4 . The elementary module according to  claim 3 , wherein the side portions of the top crosspieces of the frames and the front and rear portions of the top portions of the side walls comprise notches snap fit the ones into the others respectively. 
     
     
         5 . The elementary module according to  claim 1 , wherein the floor bears on the lower crosspieces of the frames by two front and rear grooves, provided on its lower face, snap fit onto these bottom crosspieces. 
     
     
         6 . The elementary module according to  claim 1 , wherein the inward locking of the top portions of the side walls is also provided by a roof snap fit onto the side walls by two side rebates. 
     
     
         7 . The elementary module according to  claim 6 , wherein the roof is blocked forwards and backwards by two front and rear grooves snap fit onto the top crosspieces of the front and rear frames. 
     
     
         8 . The elementary module according to  claim 1 , wherein the side walls comprise, on their external face, grooves arranged to snap fit onto the uprights of the chassis-frames which thus lock the side walls outwards. 
     
     
         9 . The elementary module according to  claim 1 , wherein, in order to be stackable, the top and bottom crosspieces of the chassis-frames comprise, on the outside, bosses and notches of complementary shapes respectively and the side walls are provided with front and rear feet arranged to bear on the side walls of an adjacent and identical lower module. 
     
     
         10 . A stack of elementary modules according to  claim 1 . 
     
     
         11 . A stack of elementary modules according to  claim 4 . 
     
     
         12 . A stack of elementary modules according to  claim 7 . 
     
     
         13 . A stack of elementary modules according to  claim 6 .
