BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a shelf and transportation system, in particular for gastronomic purposes, which comprises a mobile bearing structure including four vertical square columns which are arranged in a square, the columns having lateral surfaces which are parallel to the diagonals of the square and are connected to one another at the top and at the bottom. A transportable bearing structure, which is intended for plates and can be considered an important element of a system of this type, is known from U.S. Pat. No. 4,911,308. It serves for accommodating a multiplicity of plates which are arranged above one another resting on retaining members without contacting one another. Meals, in particular cold hors d'oeuvres, may be prepared on the plates. With the aid of a structure of this type for plates, the work surface in a large kitchen remains free. The prepared plates can be transported on the structure into a cooling area and later moved to a dining room for serving.
In the known bearing structure, the retaining members are fixedly attached to the square columns. The structure cannot be dismantled or used for other objects than plates of a particular size. Additionally, these plates can only be inserted into and removed from the bearing structure individually.
In order to prevent the deposited plates from rocking and slipping and dropping out of the fastener when jolted, e.g. when passing over a door threshold, the retaining members rise slightly away from the square columns. However, the oblique position of the plates thus caused has the disadvantage that the liquid constituents of the food prepared thereon run to one side. This inevitably leads to only plates with correspondingly solid food being deposited thereupon.
SUMMARY OF THE INVENTION
The underlying object of the invention is to provide a shelf and transportation system of the type described at the beginning which can be used in kitchen and serving operations in a variable manner and also for other objects, e.g. trays, bottles or glasses. The intention is to allow a joint loading and unloading of complete groups of such objects. Furthermore, the retaining devices for the individual plates are to be provided in such a way that they bring about a sturdy fastening of the latter, that the plates always assume a precisely horizontal position therein, and that, under these circumstances, the plates may have relatively large differences in shape and size.
The abovementioned object is achieved by the present invention, according to which a shelf and transportation system, in particular for gastronomic purposes, comprises a mobile bearing structure including four vertical square columns which are arranged in a square, the columns having lateral surfaces which are parallel to the diagonals of the square and are connected to one another at the top and at the bottom; a plurality of inserts which can be hooked onto the square columns and which have a plurality of retaining devices for objects which are to be deposited or transported, each of the inserts having a rectangular frame with horizontal and vertical legs the width of each frame corresponding approximately to the distance between two adjacent square columns of the bearing structure, and each frame being hooked in the region of its corners into hooks which are attached to the square columns. The inserts are individual structures for accommodating plates or other objects, it being possible for eight inserts, for example, to be hooked onto the bearing structure. Thus it is possible to fit the bearing structure itself, depending on requirements, with other inserts, even with several different inserts, and thus to use it for transporting or depositing the different objects. The depositing and transportation of trays is also important, two corresponding inserts, which have been hooked onto the bearing structure in each case, interacting as bearers for several trays carrying crockery. The inserts may be constructed as self-supporting individual structures and may additionally
