18156 TITLE OF THE INVENTION LOCK WITH IMPROVED PROVISIONS FOR WITHSTANDING FORCES APPLIED TO BOLT ABSTRACT OF THE DISCLOSURE A door lock including a bolt connected by a link to an actuator mechanism by which it is movable within a housing between a retracted position and an extended position. A pin and slot connection between the bolt and link form a coaction mechanism that causes a prong on the link to engage an abutment on the housing when a force is applied to the extended bolt in the direction of its retracted position. As the link pivots,a second abutment on the housing is engaged to further resist bolt movement. The force is then absorbed by the housing rather than the more fragile actuator mechanism. If the bolt is subjected to a force that would tend to pull it from the lock, the link engages another abutment on the housing to retain the bolt. The bolt is movable a short distance from its normal extended position by compressing a spring without transmitting to the link the force applied to the bolt. A hardened security pin within the bolt normally transmits the spring force to the link to avoid looseness. - 1 -
