Abstract: A linking means is disclosed for releasably connecting and quickly disconnecting two relatively discrete members in longitudinally aligned load bearing or load transmitting relationship to each other. The discrete members are connected by the coaction of hook-like flanges strategically disposed upon one member with angularly disposed retainer flanges disposed upon the other discrete member and the containment of a portion of one member between spaced outreaching flange members integrally formed upon said second member while a portion of the confronting edges of both members engage.By disengaging the confronting edges of the member and vertically moving the first member relative to said second member, a quick disconnect is achieved.

Abstract: A lift assembly for raising and lowering people and things which is especially useful for providing safe and convenient ingress and egress to and from recreational vehicles for disabled persons such as those who are confined to wheel chairs, the device having a pivotable articulated platform receiving selective vertical movement by way of a special linkage between the platform and a threaded driven shaft which in turn responds to a reversible electric motor which is actuatable by remote signal device which may be held by the operator thereof.
