Description:
BACKGROUND OF THE INVENTION 
     The invention relates to a fitting for fixing a rear wall of a drawer on a side part of the drawer such as a drawer side or runner of the drawer side, and including a supporting part which can be fixed on the side part of the drawer and having fixing lugs which engage in receiving openings in a corresponding holding part on each said or end of the rear drawer rear wall. 
     In modern furniture construction drawers are known which are made entirely by injection molding of plastics material, but drawers are also known in which the sides are produced from plastics material or a metal and which are connected to a rear wall is likewise prefabricated from plastics material or prefabricated from a metal. In many cases, particularly in smaller production runs, it is advantageous for the furniture manufacturer if, as far as the width of the drawer is concerned, he is not dependent upon prefabricated parts. That is, it is advantageous to be able to produce drawers of any width without special expenditures. 
     The object of the invention is to create a fitting which enables a rear wall, which is in particular made from a wood material or also from extruded plastics materials or the like and has been cut to a specific length, to be connected by quick assembly to a drawer side or to be connected by quick assembly to an adapter connected to the drawer side or to a runner of the drawer. 
     SUMMARY OF THE INVENTION 
     The object according to the invention is achieved in that a supporting part can be coupled by means of fixing lugs to a holding part which can be fixed, preferably screwed, on the rear wall. Each holding part has a fixing flange which is aligned parallel with rear wall and by which it can be fixed on the rear wall, and a housing portion in a side wall of which are located holes in which the fixing lugs engage. 
     By means of the fitting according to the invention it is possible for a rear wall, which has been produced so to speak as piece goods and has been produced from a cut panel of chipboard or, as already mentioned, as an extruded part made from plastics material or aluminum, to be incorporated into a modular system of a drawer to be produced from prefabricated parts.

     DETAILED DESCRIPTION OF THE INVENTION 
     As can be seen from FIGS. 1 and 2, a drawer has in the usual way two drawer sides 2, a front panel 1, a drawer base 3 and a rear wall 6 or 11. The front panel 1 is connected in the usual way to the drawer sides 2 or to runners 12 which are set into the drawer sides 2. The runners 12, which run on supporting rails 9 fixed on the side walls of a furniture body, are provided on their rear ends with respective adapters 13. The adapters are for example welded to the runners 12. 
     The adapter 13 in turn supports a supporting part 7, which is produced for example from plastics material or another injectable material and is screwed, riveted or pushed onto the adapter 13. The supporting parts 7 have fixing lugs 27 which are directed towards the interior of the drawer and are of resilient and preferably hook-shaped construction. In this case the fixing lugs 27 point towards a central plane of the drawer which is aligned perpendicular to the rear wall 6, 11 and perpendicular to the drawer base 3. 
     The rear walls 6, 11 are both produced from a chipboard material and have been cut to a desired length from a longer board. Before the drawer is assembled, each rear wall 6, 11 is screwed at opposite ends thereof to fixing flanges 14 of holding parts 5 or 10. In the illustrated embodiment the fixing flanges 14 rest against the back surface of the rear wall 6, 11. The holding parts 10 are the same height as the drawer side 2, while the holding parts 5 project above the drawer sides 2 and serve for fixing drawer rails 2a. 
     Each holding part 5, 10 has a housing like portion 15 with a side wall 16. In the side wall 16 are located fixing holes 17 which in the illustrated embodiment are disposed in the region of an edge 18 between the side wall 16 and a closure wall 19 of the housing portion 15. Closure wall 19 is aligned parallel with the rear wall 6, 11. Flange 14 and closure wall 19 are connected by a member 20, e.g. a connecting wall that extends parallel to side wall 16. Thus, walls 16 and 19 and member 20 define housing portion 15 that is open towards the rear but on the face of the rear wall 6, 11 inside the drawer wall 19 closes off or continue the inner closure surface of the rear wall 6, 11. Furthermore, the housing portions 15 are each provided at the bottom thereof with a cut-out 28 which receives the adapter 13 and the runner 12 when the holding parts 5, 10 are installed. 
     A clip 4 which holds a rail 2a can be inserted into the respective holding part 5. Each holding part 5 has an upper closure wall 21 which projects horizontally towards the rear and a side wall 16 which is of equal width and is directed towards the rear. A slot 22 is located between the walls 16, 21 in the outer upper corner of the holding part 5. The clip 4 is pushed into the slot 22. The clip 4 has a central web or bar 23 and two holding arms 24 spreading in a V shape as well as a cylindrical body portion or segment 25 with a base surface of 270°. Portion 25 has removed therefrom a cut-out in the form of a segment with an arc of 90°. Central web or bar 23 is integral with body portion 25 and extends therefrom through the cut-out. 
     The clip 4 is pushed onto the corner of the holding part 5 in such a way that the central web 23 protrudes through the slot 22 and the holding arms 24 are supporting on the inner faces of the walls 16, 21. The cylindrical portion 25 of the clips 4 rests on the outside of the walls 16, 21. In the illustrated embodiment there is disposed on the clip 4 a lug 26 onto which the rail 2a is screwed and which directly supports the rail 2a.
