Abstract
An improved shackle apparatus and a locking mechanism for the same. The shackle is of a thimble type design and includes a locking mechanism for locking the shackle open and closed. The shackle apparatus allows for secure locking, easier operation, higher strength and less susceptible to problems of wear. The locking mechanism includes a plunger pin connected to a knob that mates with the shackle body to prevent the plunger pin from rotating and/or retracting, and the shackle from opening. This design prevents the plunger from both rotational as well as translational movement during extreme flogging, dragging and impact to prevent accidental opening. The shackle can be operated with one hand for the inside surface of the hook is “proud” above the surface of the clevis. This arrangement transforms any force applied to the latching side of the shackle into a moment which helps the hook close and allows the plunger pin to be snapped closed with the use of one hand. Higher strength is accomplished by implementing a structural protrusion on the shackle body which interlocks with the hook and reduces shear stress on the plunger pin. Less susceptibility to problems of wear is accomplished by thinning the hook and providing a boss around its pivot so as to increase the clearance between any burrs or deformed metal on the clevis and hook.
