ABSTRACT:
The present invention relates to a shelf stand having individually rotatable shelves located one above the other.
From the Swedish patents Nos. 8503671 and 8601061 it is known to provide shelf stands with vertical columns and a plurality of circular shelves carried by the columns and located on top of each other. It is also known from said patents to make the contents of these shelves readily accessible in the order of use first in—first out. The shelf stands can be made in various sizes and will obtain thereby various storing, capacities.
In large shelf stands carrying heavy goods much power is consumed for starting the turning or rotation of a shelf, in spite of the fact that friction against the stationary shaft of the stand is minimized by means of ball bearings. When large shelf stands are used also more time is requested in the search for a particular product. It is desired that said search time be minimized, as a search in progress prevents other persons from searching on the same shelf at the same time.
The present invention has for its main object to eliminate the inconvenience when operating large shelf stands of the kind mentioned introductorily, so as to facilitate the search for a particular product and searching time thus be minimized.
Another object of the invention is to minimize the need for internal transports in shops, pharmacies, storage rooms and the like having computerized handling routines, where shelf stands of the said type are used.
According to the invention these and other objects and advantages are achieved by the invention obtaining the characeristic features defined in the accompanying claims.
