System for rapid mounting and removal of a carrier on and from a support frame

摘要

The system for rapid mounting and removal of a carrier on and from a support frame comprises a handle which is accessible at the front of the carrier and the ends of which are joined to two side arms pivotally mounted on two shafts. The handle is locked in the top position by means of a blade-spring device. Two studs come into position within notched portions of the arms. Each stud is attached to a spring, the other end of which is attached to the support frame. The springs are stretched in order to bring the studs into an initial stop position. After mounting of the carrier, higher tension is exerted and has the effect of locking the carrier position.
