Abstract
A latch mechanism is provided for a door which includes a rotatable latch which is rotated into and held in an open position to allow the door to open, and is released from the open position only when a sensing mechanism provided as a part of the latch mechanism, held in the door, senses the door frame upon a closing of the door. The latch is held in an over center engaged position which it is moved into due to a lost motion connection among some, but not all, elements of the latch mechanism.
