ABSTRACT:
A locking bolt apparatus includes a bolt having a fastening end with a circumferential channel around the fastening end, a bolt lock assembly including a cylindrical sleeve for receiving the fastening end of the bolt, the cylindrical sleeve having a pin slot angled with respect to the cylindrical sleeve longitudinal axis, a locking pin in the slot oriented perpendicular to the longitudinal axis of the cylindrical sleeve and having two ends extending beyond the slot, the pin positioned to laterally enter the circumferential channel, and an annular release member, slidably encircling the cylindrical sleeve, for engaging the two ends of the pin and pushing the pin out of the slot and out of the channel to release the bolt. Screw threads are preferably provided on the cylindrical sleeve, and an annular bolt adjustment member preferably surrounds the bolt adjacent to the cylindrical sleeve and has screw threads corresponding to and engaging the screw threads on the cylindrical sleeve, such that rotating the cylindrical sleeve in one direction elevates the bolt and rotating the cylindrical sleeve in the other direction lowers the bolt with respect to the annular bolt adjustment member. A spring-loaded washer is preferably provided around the cylindrical sleeve for biasing the pin into the slot.
