BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a drawer construction set comprising two metal drawer frames, each of which is provided at a rear end thereof with an inwardly directed flange and each of which has a support web for a base plate, and a metal drawer rear wall provided with hooks which can be suspended in slots in the drawer frames.
With conventional drawer construction sets, the frames and the drawer rear wall have to be screwed to one another. This clearly is very time-consuming, especially in the case of production runs of very large numbers. Generally, the rear wall in such case is made from a wood material, for example a chipboard. Metal rear walls are used in particular for office furniture, for example for filing cabinets. Here too, the drawer frame is connected by screws or rivets. In many cases, no base plate is provided.
Furthermore, drawer construction sets are known in which the drawer frames and the rear wall can be connected without a tool, simply by pushing them together. Such construction sets enable assembly to be very rapid and simple. The individual components of construction sets of this type are, however, made from synthetic material in accordance with the known prior art. Examples of such construction sets can be found in GB-A-2 087 715 and GB-A-2 101 879. However, the strength and thus the loading capacity of drawers which have been produced using such construction sets is rather limited. Furthermore, separate pull-out guide rails are required to enable the drawer to run in a pull-out guide fitting.
SUMMARY OF THE INVENTION
It is the object of the invention to provide a drawer construction set of the type mentioned above, having metal drawer frames and whereby it is possible to connect the metal drawer frames to a rear wall rapidly, and whereby it is possible to connect such parts without a tool.
Such object is achieved according to the invention in that each drawer frame has a flange having therein an opening, such that the drawer rear wall can be anchored on the flanges, and in that the drawer rear wall has, in a manner known per se, positioning lugs which project into corresponding openings in the flanges and prevent vertical displacement of the drawer rear wall with respect to the drawer frames. Advantageously, the positioning lugs are constructed in the manner of webs and the openings are slot-shaped. Also, slots in which the hooks can be suspended are upwardly open in order to facilitate suspension of the rear wall on the drawer frames.
The hooks and the positioning lugs advantageously are constructed on rearwardly bent end or marginal webs or flanges of the rear wall. In such case, the rear all advantageously has an upper horizontal web, as a result of which a stable box-type profile is formed together with the marginal webs. In order to improve stability of the drawer, it is advantageously provided for the drawer rear wall to have, above a support web for the base plate, a groove-shaped profile in which the base plate is received without play, and for a vertical web of such profile to have a step. A further feature of the invention provides for the drawer rear wall to have at least one half-knob or protrusion below which fits the base plate. The base plate thus is held between the support web and the holding knob and is prevented from being raised away. Instead of a holding knob, a horizontal holding tab punched out of the drawer rear wall and advantageously projecting into a groove by the rear end of the base plate can be provided.
A further feature provides for the drawer rear wall to have outwardly projecting holding flanges for drawer rails, the width of the holding flanges being at least approximately the same as the width of the drawer frames. A construction set of this type enables a rail to be mounted without additional holding aids.
