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.

Claims (42)

1 . 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 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; and

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 prevent the second side of the first door from dropping in a downward direction.

2 . The breakout door system of claim 1 , further comprising:

a second door with a first side having a second pivot and a second side opposite the first side, the second 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 second crawl arrester configured to move between a deployed position when the second door is not in the closed pivot position and a stowed position when the second door is in the closed pivot position, the crawl arrester mounted to one of the second door and the door frame; and

a second arrester stop mounted to the other of the second door and the door frame than the second crawl arrester, wherein when the second crawl arrester is in the deployed position, the second crawl arrester contacts the second arrester stop to prevent the second side of the second door from dropping in a downward direction.

3 . The breakout door system of claim 1 , wherein the crawl arrester moves by pivoting.

4 . The breakout door system of claim 1 , further comprising a spring biasing the crawl arrester to the deployed position.

5 . The breakout door system of claim 4 , wherein the spring is a leaf spring.

6 . The breakout door system of claim 4 , further comprising a spring projection located on the crawl arrester and configured to allow the spring to bias the crawl arrester to the deployed position.

7 . The breakout door system of claim 4 , wherein biasing the crawl arrester to the deployed position includes biasing the crawl arrester in a direction laterally away from the first door or the door frame to which the first portion of the crawl arrester is mounted.

8 . The breakout door system of claim 4 , wherein the spring is disposed vertically above the crawl arrester.

9 . The breakout door system of claim 1 , further comprising 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.

10 . The breakout door system of claim 1 , further comprising a door projection mounted on the first door and configured to engage the crawl arrester and move the crawl arrester to the stowed position when the first door is moved to the closed pivot position.

11 . The breakout door system of claim 1 , wherein the crawl arrester is dimensioned and configured to allow the first door to slide with respect to the door frame when the crawl arrester is in the stowed position.

12 . The breakout door system of claim 1 , wherein the arrester stop extends laterally away from the first door or the door frame to which the arrester stop is mounted.

13 . 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.

14 . The method of claim 13 , further comprising urging the spring against the spring projection on the crawl arrester.

15 . The method of claim 13 , further comprising allowing the door to slide past the arrester stop when the crawl arrester is in the stowed position.

16 . The method of claim 15 , wherein moving the crawl arrester is done by pivoting the crawl arrester.

17 . The method of claim 16 , wherein the pivoting is done by engaging the rocking projection on the crawl arrester with a protrusion on the door as the door approaches and achieves the closed pivot position.

18 . 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.

19 . The breakout door system of claim 18 , further including a door projection mounted on the first door and configured to engage the crawl arrester and move the crawl arrester to the stowed position when the first door is moved to the closed pivot position.

20 . The breakout door system of claim 18 , further comprising:

a second 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 second crawl arrester configured to move between a deployed position when the second door is not in the closed pivot position and a stowed position when the second door is in the closed pivot position, the crawl arrester mounted to one of the second door and the door frame; and

a second arrester stop mounted to the other of the second door and the door frame than the second crawl arrester, wherein when the second crawl arrester is in the deployed position, the second crawl arrester contacts the second arrester stop to limit the second door from moving past a threshold amount toward the open slide position.
