Dual motion, quick release latch mechanism

A latch mechanism comprising:

• a) a bolt movable between retracted and extended positions mounted in a recess in a door with an exterior and an interior surface said latch mechanism cooperating with a strike plate in the extended position said strike plate mounted in a recess in a door frame;
• b) an exterior handle mounted on the exterior surface of said door;
• c) an interior handle mounted on the interior surface of said door;
• d) a bar having a linear axis and mounted for rotational and for linear movement about said axis and having a cam surface wherein the bar extends through the recess in the door and is attached to the exterior and interior handles;
• e) a receiver with a cam follower in contact with said cam surface, wherein the receiver is actuated by the bar when said handles are moved in a linear direction along said axis, wherein the receiver is further actuated by the bar when said handles are moved rotationally about said axis;
• f) a lever with an ear mounted inside a barrel housing by a rivet wherein the barrel housing guides said receiver and bolt wherein an edge on the receiver will contact the ear of the lever causing the lever to rotate about the rivet within a bolt lever slot in said bolt, retracting the bolt into the barrel housing from the strike plate;
• g) a spring contained within the barrel housing between the bolt and the receiver;
• h) an exterior plate with internally threaded studs secured to an interior plate with screws through the barrel housing apertures and a bracket;
• and
• i) a slidable lock plate with a lock tang that can engage an interior handle lock aperture providing a means of locking said bolt, said lever, and said receiver against said linear and against said rotational movement of said handles.
