Patent ID: 8276948

Claim:
A lock mechanism for being disposed in a lock frame of a door hingedly mounted to a door frame, the lock mechanism being configured for selectively allowing the door to be moved in a door opening direction from a closed position within the door frame, the lock mechanism comprising: a latch bolt having an opening defined therein, wherein the latch bolt is configured for moving between an extended position and a retracted position, wherein the latch bolt is in the extended position to prevent movement of the door in the door opening direction, and wherein the latch bolt is in the retracted position to allow the door to be moved in the door opening direction; a slider configured for being moveably positioned within the opening between a blocking position and a release position, wherein the slider prevents movement of the latch bolt from the extended position when in the blocking position, and wherein the slider allows the latch bolt to move to the retracted position when in the release position; a cam driver rotatably associated with the lock frame about a first pivot axis; a handle connected to the cam driver; and a cam configured to move the slider to the release position and configured for being selectively connected to the cam driver in one of a first position and a second position, wherein the cam is reversible so that when the cam is connected to the cam driver in the first position the connection allows for the cam to move the slider to the release position when the handle is rotated in a first rotational direction, and so that when the cam is connected to the cam driver in the second position the connection allows for the cam to move the slider to the release position when the handle is rotated in a second rotational direction, wherein the first rotational direction is opposite to the second rotational direction.
