Breakout crawl arrester

A method of stopping a door with a first side having a first pivot and a second side opposite the first side, the door configured to selectively slide and pivot between an open and closed slide position and an opened and closed pivot position with respect to a door frame, the method comprising:

• moving a crawl arrester comprising a first portion and a second portion to a deployed position when the door is not in the closed pivot position, the first portion of the crawl arrester mounted to one of the door and the door frame, wherein as the crawl arrester moves to the deployed position, the second portion of the crawl arrester moves away from the one of the door and the door frame to which the first portion of the crawl arrester is mounted;
• contacting the second portion of the crawl arrester against an arrester stop mounted to the other of the door and the door frame when the crawl arrester is in the deployed position to prevent the second side of the door from dropping in a downward position and to limit the door from moving past a threshold amount toward the open slide position;
• biasing, with a spring, the crawl arrester to the deployed position;
• allowing, with a spring projection located on the crawl arrester, the spring to bias the crawl arrester to the deployed position;
• and
• moving, with a rocking projection located on the crawl arrester, the crawl arrester to a stowed position when the door is in the closed pivot position.

A breakout door system comprising:

• a door frame;
• a 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 comprising a first portion and a second portion, the crawl arrester configured to move between a deployed position when the first door is not in the closed pivot position and a stowed position when the first door is in the closed pivot position, the first portion of the crawl arrester mounted to one of the first door and the door frame, wherein as the crawl arrester moves to the deployed position, the second portion of the crawl arrester moves away from the one of the first door and the door frame to which the first portion of the crawl arrester is mounted;
• an arrester stop mounted to the other of the first door and the door frame than the crawl arrester, wherein when the crawl arrester is in the deployed position, the second portion of 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 and configured to move the crawl arrester to the stowed position when the first door is in the closed pivot position.
