<p>Rolling shelves comprise several similar shelf elements that can be moved on multiwheel undercarriages on rails (10a, 10b, 11as, 11b) sunk into the floor, opening an access path to the desired element between any two other elements. Both double-axis and double-wheel undercarriages of each shelf element are mirror-symmetrical and run on corresponding offset pairs of rails (10a, 11a or 10b, 11b) of each undercarriage. The four points of contact (4a, 4b, 5a, 5b) between the wheels and the rails form the axially symmetrical corners of a trapezium, the parallel sides of which coincide from the top view with the two wheel axes (12, 13) of the undercarriage. The shelf element moves along the axis of symmetry (19). Two vertical or inclined stays (18a, 18b) that extend from two wheel cases (9a, 9b) maintain the carrying frame in an inclined position which makes it easier to vertically deposit the goods to be stocked and to vertically remove them from the support structures of stocked goods arranged on the carrying frame (15). An open space is created between the carrying frame (15) and the stays (18a, 18b) that extend from the wheel cases (9a, 9b), through which the next shelf element can move with its projection formed by its inclined carrying frame (15) and its attached undercarriages.</p> |
