Abstract:
Chain store comprising two continuous chains which together carry gondolas serving for holding goods and are driven together by gear wheels or chain wheels rigidly connected to one another, each chain being guided by means of at least three upper and three lower stationary deflection pulleys and by means of deflection pulleys, two each of which are freely rotatably mounted one on top of the other in a vertically displaceable carriage, in such a waythat the chain in each case passes from an upper stationary deflection pulley perpendicularly downwards to an upper deflection pulley of a carriage and from there perpendicularly upwards to the next stationary upper deflection pulley that it in each case passes from a lower stationary deflection pulley perpendicularly upwards to the lower deflection pulley of a carriage and from there perpendicularly downwards to the next stationary lower deflection pulley, that it passes from the last upper stationary deflection pulley to the last lower stationary deflection pulley and from the first lower stationary deflection pulley to the first upper stationary deflection pulley, on the one hand a loading station and on the other hand an unloading station being provided on the two outer sides of the chain, and one drive apparatus each being coordinated with the loading side and unloading side and each- driving the upper or lower stationary outermost deflection pulley coordinated with the loading side or unloading side, wherein additional drive means are present for optionally moving the carriages vertically, independently of the driving of the loading and unloading side.
