ABSTRACT:
A releasable, hook-type fastener of the kind intended to secure pieces of equipment or structural members together, the fastener including a casing, a drive shaft turnable in the casing, an eccentric bushing carried by the casing and turnable with the shaft, and a pair of separate and distinct, similarly-shaped spring hooks that are disposed side by side and substantially in broadside contact with each other. At one end, the hooks have looped bearing portions which are frictionally engaged with the eccentric bushing, and at the other end they have registered bill portions. A pin is provided, separate from the hooks and adjacent to the eccentric bushing, for engagement with the hooks so as to maintain them in registration with one another. The arrangement is such that an unusually strong and sturdy construction results, without the need for heavy gauge springs and without the use of odd-shaped springs which would require special metal stock and bending fixtures or jigs for their fabrication.
