ABSTRACT:
The lifting down apparatus for a multi-stage shelf assembly comprises a base, a pair of arms pivotally secured to the base so as to form a parallel linking mechanism together with the base, and foldable frames having link members which connect with the arms, a plurality of rotary shelves pivotally mounted onto one of the arms of the foldable frames at their basic portions by spacing in the longitudinal direction, supporting members attached to the other arm so that they may support the free end portions of the rotary shelves, whereby when the foldable frames rise from the base, the rotary shelves separate stepwisely, and when the foldable frames fall down, the rotary shelves arrange on the same plane. Accordingly, delivery efficiency can be greatly improved.
