PURPOSE: A latch mechanism, such as may be found in a door is provided which is actuated either by pushing or pulling or turning a handle or a knob. CONSTITUTION: A latch mechanism which includes exterior and interior handle assemblies connected by a bar with a cammed surface such that the latch mechanism can be actuated by pushing, pulling, or turning a handle. Pushing or turning the exterior handle causes the bar to contact a cam follower on a receiver whose edge will rotate a lever to retract a bolt. Also, pulling or turning the interior handle produces the same result. Once the bolt is retracted, and the handle is released, a spring biases the bolt back to the extended position.
