Abstract
A bolt lock including a lock barrel having a central opening cylindrical about a central axis and extending between an open front end and a closed rear end. The lock barrel has bolt openings extending outwardly from opposite sides of the central opening adjacent the lock barrel rear end, with a pair of bolts received in opposite bolt openings. Each bolt has a head on one end, a leg on the other end with a rear side having a spring groove, and a front side with an axially extending shoulder. The bolt shoulders are planar and parallel to one another. The spring grooves are open at the end of the leg and parallel to and equidistant from a radius of the central axis. The bolts have their other ends in the central opening adjacent one another with the bolt legs substantially side by side when in a retracted position. A compression spring has one end disposed in one bolt spring groove and a second compression spring has one end disposed in the other bolt spring groove, where each spring extends from the open end of the groove and bears against the other bolt to bias the bolts apart. A lock plug in the barrel central opening has a pair of control lugs extending toward the barrel rear end. The lugs axially overlap with the bolt shoulders and the springs bias the bolts apart so that one shoulder engages one lug and the other shoulder engages the other lug.
