DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention pertains to a base for machines, devices, scaffolds and the like, in which posts and struts made of extruded light-metal sections are assembled into a three-dimensional framework and are connected to wall elements, wherein the post front surfaces facing upward are closed by cover sections, e.g., those made of plastic.
BACKGROUND OF THE INVENTION
Such bases and extruded light-metal sections have become known from the 1989 issue of the "MB System" complete catalog of ITEM GmbH, Solingen. The extruded sections have a square cross section and have, on their side surfaces, grooves of an undercut design, which are intended for the introduction of fasteners. In the core area, the prior-art section has a continuous cylindrical channel, which is intended for screwing in fasteners on the front side.
Such extruded light-metal sections can be assembled into a three-dimensional framework, in which the problem is how the free spaces remaining between the posts and struts are to be covered. Wall elements, which have fittingly designed connecting elements at their edges, in order to be inserted into the grooves extending along and on the posts and struts, have been developed for this purpose. The consequence of this is the arrangement of the wall elements in the space circumscribed by the posts and the frame. However, this makes the mounting and the removal of such wall elements complicated, because these can be displaced, together with their connecting elements, only along the grooves of the posts and Struts, which is not readily possible without disassembly in a finished framework. As a consequence of this, the wall elements must be detached from their fasteners to lift them off vertically from the framework, in order to avoid this disassembly. This measure is also impractical and cumbersome especially when the base for machines and devices, in which repeated removal of the wall elements during assembly is often indispensable, is to be formed with the framework.
SUMMARY AND OBJECTS OF THE INVENTION
The basic task of the present invention is to simplify the design and the arrangement of wall elements for such a framework such that assembly and disassembly will be facilitated and the overall optical appearance is improved.
Based on the state of the art described in the introduction, the essence of the present invention is that the individual wall element has a width corresponding to the distance between the centers of adjacent posts; that it is in contact with the outer surfaces of the posts by means of space-forming members; and that it extends, with a bent upper web, over a partial area of the upper front surface of the post, and the cover section is recessed in this partial area.
The wall element according to the present invention can thus be attached to the posts and struts of the framework from the outside, and centering of the position in two directions is ensured by the fact that the individual wall element is in contact with the outside of the posts and struts and is supported on the upper front surface of the posts and of the upper strut. Lateral displacement of the wall element can be avoided by the peripheral edges of the bent upper web being guided at the recesses of the cover section. Centerings of another design are, of course, possible as well.
The wall element thus mounted can be fastened in the conventional manner. It is possible, e.g., to arrange centering pins, which engage corresponding centering holes of the framework during the attachment of the wall element, at the lower edge of the wall element. Bolts or other similar connecting elements, which can be easily closed and open, may be provided at the upper edge of the wall element in this case.
Thus, the advantage of the design according to the present invention is that the assembly and disassembly of the wall element can be carried out in a very simple manner, without disassembly of the framework. In addition, the overall optical appearance of the base or frame is improved, because the wall elements
