A latch mechanism which includes exterior (20) and interior (30) handle assemblies connected by a bar (10) with a cammed surface (10C) 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 (12) on a receiver (2) whose edge will rotate a lever (8) to retract a bolt (7). Also, pulling or turning the interior handle produces the same result. Once the bolt is retracted, and the handle is released, a spring (4) biases the bolt back to the extended position.

Mécanisme de verrou comprenant des ensembles poignée extérieur (20) et intérieur (30) reliés par une barre (10) possédant une surface à cames (10C), de manière à pouvoir actionner le mécanisme de verrou en poussant, en tirant ou en tournant une poignée. La poussée ou la rotation exercées sur la poignée extérieure provoque l'accouplement de la barre avec une contre-came (12) sur un élément de réception (2) dont le bord fera tourner un levier (8) afin de tirer un verrou (7). La traction ou la rotation exercée sur la poignée intérieure produit le même résultat. Une fois que le verrou est tiré et que la poignée est relâchée, un ressort (4) sollicite le verrou afin qu'il revienne en position étendue.
