Abstract
A device for raising and lowering a transfer step provided at one end of a vertically movable table in a lift includes a lug projecting from the step and an axially movable rod extending along the table and having one end linked to the lug. The rod has a laterally projecting pin near the other end thereof located remotely from the step. A handlebar is rotatably supported near the other end of the rod. A pin driving member is connected to the handlebar rotatably therewith and has a slot in which the pin is slidably fitted. The slot extends radially of the axis of rotation of the pin driving member. When the handlebar is rotated to rotate the pin driving member, the pin slides along the slot to cause the axial movement of the rod to rotate the step from one of its raised and lowered positions to the other. The slot includes a laterally projecting portion forming an arcuate contour having its center at the axis of rotation of the pin driving member, so that the pin may be held in the laterally projecting portion of the slot when the step stays in its raised position.
