Abstract
A safety vent preferably for use in a high rise building for permitting the escape of smoke and fumes and comprising a fixed frame accommodated by an opening in the building, a movable frame pivotally secured to the fixed frame and means for biasing the movable frame to an open position. In the preferred embodiment the movable frame includes panel means and pivots at its lower end. A latch mechanism maintains the movable frame in a closed position while a release mechanism, operated either electrically or pneumatically, can be energized to permit opening of the vent. Limiting means in the form of shock absorbers or snubbers interconnect between frames for limiting the open position of the vent.
