Title: Rotary door latch

Abstract: A latch carried by a door is rotatable about a vertical axis. The rotary latch member has a portion which engages a stationery striker plate on the door jamb which rotates the latch as the door moves to the closed position. Rotation of the latch causes a notch in the latch to engage either side of a post in the striker plate. The latch member continues to rotate until the door is fully closed by the interaction of the post with the notch. A releasable detent member locks the rotary latch against further rotation in either direction when the door reaches the fully closed position.
