ABSTRACT:
A mechanism for lifting a platform while maintaining it substantially parallel to a mobile support member, and for simultaneously moving it horizontally with respect to the support member. The mechanism includes scissor elements each having limbs comprising three nesting telescopic elements. The largest diameter element of each set is attached to the support member, while the medial elements of the several sets are connected with each other. The limbs are separately adjustable, so that the platform is movable along selectable vectors.
