ABSTRACT:
A door latch mechanism with a vertically linearly translatable operating member that is manually movable to unlatch a door. The mechanism, which includes a locking assembly, is locked by rotational movement of the operating member. A foil member connects with the operating member centrally and has ends wound into chambers. The foil, movable with the operating member vertically, closes a slot in which the operating member moves. The connection of the operating member with the foil permits rotational movement for locking. A rotational latch cooperates to hold the operating member in its rotated, locked position, against the bias of springs urging unlocking rotational movement of the operating member.
