ABSTRACT:
Lift apparatus by which wheelchair invalids are lifted from one location, through a spiral, to another location. The lift apparatus includes coacting movable and fixed support members which are telescopingly received within one another to form a variable chamber therebetween.
A cantilever arm is affixed to and radially extends from the movable support member. A pair of spaced arms are affixed to the cantilever arm and removably engage a chair. The cantilever arm is adjustably affixed to the movable support member such that the arm can be adjustably positioned along any radial extending from the axial centerline of the support members.
A cam means is jointly associated with the two support members in such a manner that when fluid pressure telescopes the two support members apart, the cantilever arm is rotated 45.degree. towards the end of the upstroke and thereafter, the cantilever arm is rotated another 45.degree. as the chair is lowered back into proximity of the original elevation.
