Abstract
Disclosed are door assemblies particularly well suited for opening and closing wide entries such as emergency room entries. The assemblies have multiple doors that can be overlapped at a side of the entry. If further access room is needed the doors can then be pivoted so that essentially the entire entry is open. There is an automatic latching system that activates as the doors are being pivoted to prevent some sliding motion during the pivoting.
Claims8
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.

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