Patent attributes
A lock bolt release system operable with a door bolt supported by a door providing access to a secure area. A pawl is pivotally mounted on a distal end of a lock bolt, and the pawl is pivoted by operation of the door bolt prior to the lock bolt being movable by the door bolt. A wedge block is movably mounted on the lock bolt and is effective to block motion of the pawl and the door bolt. A stop member is located adjacent the wedge block and blocks motion of the wedge block, thereby preventing the door bolt from being disengaged from the structure. The stop member is movable, which permits the wedge block to be moved by the pawl and the door bolt to contact and move the lock bolt, thus, permitting the door bolt to be disengaged from the structure.
