Abstract:
1. A latch mechanism comprising: a pushbutton lock having a pivotable cam, the pivotable cam being movable from a locked position to an unlocked position; at least one support plate that is mounted between a spring and a lock cam, a latch fork pivotally supported from the support plate; the lock cam that is pivotally supported from the support plate, the lock cam being movable from a first position where the lock cam prevents rotation of the latch fork to a second position where the lock cam does not interfere with the movement of the latch fork, the lock cam further comprising a lever that is rigidly attached to the lock cam and which extends away from the lock cam so that the lock cam is positioned between the lever and the latch fork, the lever being mounted next to the pushbutton lock to cooperate with the pivotable cam through direct contact with the pivotable cam of the pushbutton lock when the pushbutton lock is in the unlocked position, so that pressing pushbutton lock will cause the lock cam to rotate the lock cam to the second position; the spring, the spring being attached to the latch fork and the lock cam and extending between the latch fork and the lock cam so that the spring biases the lock cam towards the first position while biasing the latch fork to a release position.
