Abstract:
1. A latch for coupling a first object to a second object and capable of moving from an engaged to disengaged position along an axis of operation, the latch comprising: a large headed element including an enlarged head and a connector projecting from the enlarged head; a housing having an internal space extending entirely therethrough along an axis of operation; a receptacle, having an open interior and an interference element, wherein the receptacle is fixed to the housing, and the receptacle is received within the internal space of the housing, wherein when the latch is in the engaged position, the receptacle is disposed selectively to entrap the enlarged head of the large headed element within the receptacle by the interference element, and when the latch is in the disengaged position, the receptacle is disposed to release the enlarged head of the large headed element from entrapment within the receptacle; a push button assembly which serves as a manual actuator to disengage the latch by enabling the interference element to release the enlarged head of the large headed element from interference therewith by linear action, wherein the push button assembly includes a return spring disposed between the pushbutton assembly and the receptacle so that the return spring is able to expand and contract along the axis of operation when the latch moves between the engaged and disengaged positions, wherein the enlarged head of the large headed element is separate from the housing and releasably entrapped within the receptacle; and a locking piston disposed within the open interior of the receptacle and disposed to move along the axis of operation, wherein when the latch is disengaged by depressing the manual actuator of the push button assembly, a pusher spring, disposed within the open interior of the receptacle between the receptacle and the locking piston, and disposed to expand and contract along the axis of operation, expands thereby forcing the locking piston to move along the axis of operation and eject the enlarged head of the large headed element from the receptacle and into a position to maintain contact with the interference element thereby allowing the reinsertion of the enlarged head of the large headed element into the receptacle when the latch is in the disengaged position.
