Abstract
A rapid engagement pin joint, for interconnecting two units which are intended to rotate through a limited range of angular motion relative to one another, comprises a pair of plates one of which includes a pair of slots that open into an edge thereof and the other of which has a pair of outstanding pins adapted to be inserted into the open ends of said slots. One of the slots is configured as the arc of a circle while the other slot is oriented in nonparallel diverging relation to said one slot and defines a single location, e.g., the innermost end of said other slot, about which said one slot is concentric. The pin joint can be employed to effect rapid engagement between an antenna reflector and an antenna support structure.
