Abstract
A wall vent preferably for use in a high-rise building is releasably opened for venting a fire in the building. The vent comprises a frame, a window or venting panel that is pivotally for biasing the venting panel to an open position and latch means for maintaining the panel in a closed position. The latch means may be either manually or electrically released or released upon detection of heat or smoke, and may be released either at the panel or remotely. Each wall vent is also preferably releasable to an open position from a story of the building therebelow.
Claims24
A vent for a building comprising;
- a fixed frame,
- a movable frame adapted to fit within said fixed frame when in a closed position,
- a panel means for insertion into said movable frame,
- means for pivotally securing said movable frame to said fixed frame,
- means for urging said movable frame to an open position,
- latch means for maintaining said movable frame in the closed position,
- means for releasing said latch means to permit said movable frame to move to its open position,
- and means for limiting the open position of said movable frame including a pair of shock absorbers secured at opposite ends to said fixed frame and movable frame respectively,
- said fixed and movable frames each including spaced walls with the walls of the fixed frame facing the walls of the movable frame and being interdigitally arranged to form a space between one wall of the fixed frame and one wall of the movable frame for accommodating the shock absorbers,
- said means for urging not operable even though said releasing means is operable when the outside wind velocity is greater than a predetermined velocity.

A vent for a building comprising:
- a fixed frame,
- a movable frame adapted to fit within said fixed frame when in a closed position,
- a panel means for insertion into said movable frame,
- means for pivotally securing said movable frame to said fixed frame,
- means for urging said movable frame to an open position,
- latch means for maintaining said movable frame in the closed position,
- means for releasing said latch means to permit said movable frame to move to its open position,
- and means for limiting the open position of said movable frame including a pair of shock absorbers secured at opposite ends to said fixed frame and movable frame respectively,
- said fixed and movable frames each including spaced walls with the walls of the fixed frame facing the walls of the movable frame and being interdigitally arranged to form a space between one wall of the fixed frame and one wall the movable frame for accommodating the shock absorbers,
- said means for urging including a torsion member having a biasing force insufficient to cause opening of said movable frame when the outside wind velocity is greater than a predetermined velocity.
