DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a device for padding corners of bodies, for instance on equipment housings, having two arms joined to each other at an angle and having cheeks disposed on the outside of the arms, the arms having longitudinally extending through holes.
BACKGROUND OF THE INVENTION
Known devices of this kind, as known from U.S. Pat. No. 4,801,018 and also known as padded corner protectors and made from a suitable plastic, are all embodied rigidly and adapted to the applicable shape, and in particular the width, of the particular body or housing. This means that for each housing width, one specially dimensioned padded corner protector has to be manufactured and kept in inventory. This is not only expensive financially but also time-consuming in packaging.
From German Patent Disclosure DE 29 51 402 A1, it is known to embody protective covers for articles of the most various sizes, but in that reference the arms are shaped meanderingly between the cheeks, which is complicated and expensive to manufacture, requires considerable space, and does not lead to a good padding effect.
SUMMARY OF THE INVENTION
The object of the present invention is therefore to provide a device for padding body corners of equipment housings, for instance, as noted at the outset, which can be used in manifold ways, in other words on body edges over a particular width range and conforms tautly to it yet is nevertheless simple to manufacture.
To attain this object, in a device for padding corners of bodies, for instance of the equipment housings, of the type referred to, each arm has a honeycomblike structure that can be elastically stretchable in its transverse direction.
As a result of the provisions of the present invention it is possible to cover various widths of equipment housings, furniture regions and the like that are to be covered or padded over a certain range of width differences, for instance from 60 to 100 mm. Because of the elastic stretchability of the structure, which is like a honeycomb, i.e., honeycomblike, the device can rest with initial tension on the body corners or the side regions thereof, thus assuring that the device will hold tautly in every case to the applicable body corner. Easy manipulation is assured, for instance for further packing of the housing or the like in a cardboard box. The device can be produced economically in terms of expense and material.
An advantageous embodiment of the honeycomblike structure of the arms is that the arms have at least two honeycomblike elements whose through openings, which extend vertically to the longitudinal and transverse extensions of the arms, have an inside diameter substantially greater than the thickness of the walls of the honeycomblike elements, and the two honeycomblike elements, disposed side-by-side in the direction of the transverse extent, are joined together by at least one expansion rib. When the arms are pulled apart, or by means of the cheeks, the two honeycomblike elements disposed side by side in each arm can deform in such a way that they become larger in their transverse extension and smaller in their longitudinal extension. Because of the elasticity of this shape change, an initial tension is produced by means of which the cheeks rest tautly against the side regions of the body corners to be protected. It will be understood that it is also possible to form the arms from more than two side-by-side honeycomblike elements, depending on the width of the body corner to be covered and on the elasticity of the material used.
To further improve and increase the range of elasticity of the individual honeycomblike elements or of the entire arm, the honeycomblike elements are embodied as at least partly curved on at least their inner wall, in which curved region the one expansion rib is disposed, with the inside wall of the honeycomblike element being concave and the expansion rib is embodied as curved, preferably convex on the outside are contemplated, individually or in combination.
