Patent ID: 7451802

Claim:
A door assembly for mounting across an entry, comprising: a header; a door mounted for sliding movement along the header, a member extending from the door; a pivot base having an actuator and a latch configured to capture said member of the door; a panel positioned for pivoting on the pivot base relative to the header; the door being capable of sliding between a first position where the door and panel are at least partially overlapped with respect to each other, and a second extended position where the door is less overlapped with respect to the panel than in the first position or not overlapped with the panel; whereby the assembly is configured such that contact of the panel with the actuator when the panel is positioned essentially parallel to the entry facilitates unlatching of the door to permit it to slide along the header and entry; and whereby pivoting of the panel to a position not essentially parallel with the entry automatically facilitates the actuator causing the latch to capture the member to inhibit sliding movement of the door along the header, while permitting pivoting of the door when the panel pivots.
