ABSTRACT:
This quick-release mechanism has a tubular housing in which a spring is compressed by a set of jaws fastened to a plunger within the spring. A detent is adjustably secured to the housing. When the spring is compressed by movement of the jaws far enough to clear the detent, the plunger and jaws will pass through the spring and the plunger and housing are disengaged. The housing and the plunger are the points to which opposing tensile forces are applied.
