ABSTRACT:
A bolt lock, for receiving and locking the end of a bolt having a head portion with a locking shoulder, said lock comprising a housing having internal jaws forming a central aperture, said jaws being expansible to allow the head of the bolt to snap through the opening so the the bolt shoulder latches behind the jaws. The jaws are retained in the housing above an aperture in the body which receives the inserted bolt head and below a bolt aperture in the upper portion of the housing, so that when the bolt is assembled, axial movement thereof causes the edges of the apertures to contact the internal jaws around and in spaced relation to the central aperture thereof. The jaws have upper and lower surfaces which are slightly inclined toward each other in relation to the axis of the central opening from the central aperture to the periphery of the jaws. The surface of the jaws therefore contact the edges of the upper and lower apertures at a slight angle to the axis thereof, so that vertical forces applied to the jaws by impacts to the bolt or housing tend to force the jaws toward the closed position.
