Abstract
A storing installation comprises two endless chains supporting a load for the conveyance thereof along a conveyance path and travelling in opposition to said conveyance path in a return path having more tightly curved portions than said conveyance path, to formed closed chain paths, and a frame for supporting said chains via at least one series of rolling elements arranged between said frame and the respective chain. Each chain comprises links overlapping one another in such a manner that the chain and the frame form an essentially closed channel for the rolling elements throughout the tighter return path.
Claims9
A storing installation which comprises two endless chains (9, 10) supporting a load for the conveyance thereof along a conveyance path and travelling in opposition to said conveyance path in a return path (13, 14) having more tightly curved portions than said conveyance path, to form closed chain paths, and a frame (11, 12) for supporting said chains via at least one series of rolling elements (26) arranged between said frame and the respective chain (9, 10), characterised in that each chain (9, 10) comprises links (17, 19) overlapping one another along the upper side and one edge side of the chain and hingedly interconnected at the other edge side of the chain along axes perpendicular to the longitudinal direction and the lateral direction of the chain, such that the chain (9, 10) and the frame (11, 12) form an essentially closed channel for the rolling elements (26) also throughout the tighter return path (13, 14) where the links are swung out from one another about said axes.
