Abstract
A breakout door system is provided which may include: a door frame; a first door configured to selectively slide and pivot between an open and closed position slide position and an opened and closed pivot position with respect to the door frame; a crawl arrester configured to move between a deployed position when the first door is not in a closed pivot position and a stowed position when the first door is in a closed pivot position, the crawl arrester mounted to one of the first door and frame; and an arrester stop mounted to the other of the first door and frame than the crawl arrester, wherein when the crawl arrester is in the deployed position, the crawl arrester contacts the arrester stop to prevent the second side of the first door from dropping in a downward direction.
Claims20
A breakout door system comprising:
- a door frame;
- a first door with a first side having a first pivot and a second side opposite the first side, the first door configured to selectively slide and pivot between an open and closed slide position and an opened and closed pivot position with respect to the door frame;
- a crawl arrester configured to move between a deployed position when the first door is not in a closed pivot position and a stowed position when the first door is in a closed pivot position, the crawl arrester mounted to one of the first door and frame;
- and
- an arrester stop mounted to the other of the first door and frame than the crawl arrester, wherein when the crawl arrester is in the deployed position, the crawl arrester contacts the arrester stop to prevent the second side of the first door from dropping in a downward direction.
A method of stopping a door configured to selectively pivot and slide comprising:
- moving a crawl arrester to a deployed position when the door is not in a pivot closed position;
- and
- butting the crawl arrester against a slide stop when the crawl arrester is in a deployed position.
A breakout door system comprising:
- a door frame;
- a first door configured to selectively slide and pivot between an open and closed position slide position and an opened and closed pivot position with respect to the door frame;
- a crawl arrester configured to move between a deployed position when the first door is not in a closed pivot position and a stowed position when the first door is in a closed pivot position, the crawl arrester mounted to one of the first door and frame;
- an arrester stop mounted to the other of the first door and frame than the crawl arrester, wherein when the crawl arrester is in the deployed position, the crawl arrester contacts the arrester stop to limit the first door from moving past a threshold amount toward the open slide position;
- a spring biasing the crawl arrester to the deployed position;
- a spring projection located on the crawl arrester and configured to allow the spring to bias the crawl arrester to the deployed position;
- and
- a rocking projection located on the crawl arrester, configured to move the crawl arrester to the stowed position when the door is in a closed pivot position.
