DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a retaining system for casters and slides the system including at least one retaining device which can be attached to the bottom of cabinet-like receptacles.
Cabinet-like--or chest-like--receptacles provided with casters or slides are those which, among other things, have a solid bottom panel, for example rolling containers, office containers, cabinets or devices. In many cases the bottom panel is exclusively used for stabilization and does not have a function as a pigeon hole or dust protector, particularly in those cases where there are drawers directly above the bottom panel. If required, casters or slides are fastened on this bottom panel.
BACKGROUND OF THE INVENTION
It is known to fasten casters or slides in special retaining devices, which then, in turn, are fixed by bolting, inserting, welding or gluing to the bottom panel of a cabinet-like receptacle, as a rule respectively one at each of the four corners of the bottom panel. This results in an elaborate construction and a time-consuming work process.
It is thus an object of the invention to provide a retaining device for casters and slide which obviates the disadvantages associated with the prior art.
SUMMARY OF THE INVENTION
According to the invention, a retaining device for casters and slides fulfills a stabilizing function for a cabinet-like receptacle by being configured to serve as the bottom panel of the cabinet-like receptacle.
Thus, in the present the invention, the retaining device is attached directly to the cabinet-like receptacle, which is open at its bottom, instead of being attached to a bottom panel of the receptacle first, as has been customary up to now. Because the retaining device simultaneously takes over the function of a bottom panel, a reduction of the structural components and simplification of assembly of the system are achieved.
BRIEF DESCRIPTION OF THE DRAWINGS
Exemplary embodiments of the invention are illustrated in the drawings and will be described in detail below. Shown respectively on a reduced scale are in:
FIG. 1, a perspective view of front and rear retaining devices mounted on side walls of a cabinet open at its bottom;
FIG. 2, a cross sectional view of a retaining device having a caster fastened thereto with a dowel and bolt connection as the fastening means;
FIG. 3A, a front elevational view of the retaining device with an additional dust cover and with a device for receiving a decorative panel;
FIG. 3B, a front elevational view of the device for receiving a decorative panel shown in FIG. 3A;
FIG. 4A, a cross sectional of a retaining device having a caster fastened thereto with reinforcing pins as the fastening for thin side walls;
FIG. 4B, a cross sectional view of the reinforcing pin of FIG. 4A fastened to a thin side wall;
FIG. 5, a view corresponding to FIG. 1, a single retaining device occupying the entire bottom of the cabinet;
FIG. 6A, a top plan view of a single retaining device for application in a corner of a cabinet-like receptacle;
FIG. 6B, a side elevational view of the single retaining device of FIG. 6A;
FIG. 6C, a longitudinal cross-sectional view of the single retaining device of FIG. 6A.
DETAILED DESCRIPTION OF THE INVENTION
Each one of the retaining devices selected as an exemplary embodiment has a plastic bracket 1. The plastic bracket 1 is embodied in the conventional manner as an injection-molded part with reinforcement ribs, bars or the like. The plastic bracket has a plate 11 in the area of its front/corners. A metal plate 2 has be embedded into the plastic bracket 1 in the area of the plate 11, or it may be injected into the plastic bracket during injection molding. The metal plate 2 is provided with a pin 21. Each pin 21 receives a caster 3 or a slide, not shown. The pins 21 for the casters 3 are suitably attached in such a way that the latter partially project into the plastic bracket 1. This makes possible a lesser bottom clearance 22 than with conventional retaining devices. Dowels 12 and a bar 13 are formed on the front
