Abstract
An emergency escape wall structure actuated either by pressure against the wall or automatically actuated by the presence of heat, smoke, gas, or oxygen deficiency detectors or push buttons, any one of which actuates the automatic means or by a hand lever which manually opens the structure. Upon actuation, an escape panel falls outwardly and downwardly creating a massive opening to permit the escape of a large number of persons in a brief time period.
Claims10
An emergency escape wall structure situated between two side frames, a header frame and a sill frame, said structure comprising:
- a top panel rigidly mounted between the two side frames and the head frame, said top panel having a bottom member with a recess therein;
- a bottom panel rigidly mounted between the two side frames and the sill frame;
- an escape panel having an inside sheet and having a top member with a slot therein, said slot being aligned with the recess in the bottom member of the top panel, said escape panel having a lower edge adjacent said bottom panel;
- hinge means mounted at the lower edge of the escape panel for pivotably mounting said escape panel between said side frames and said top panel and said bottom panel, said hinge means being adapted to permit said escape panel to pivot outwardly and downwardly;
- a plunger lock slidably mounted within said escape panel to move in and out through the slot in the top member of the escape panel into the recess of the bottom member of the top panel;
- spring means engaging said plunger lock and adapted to urge said plunger lock through said slot into said recess, said plunger lock having an inclined surface and said recess having a corresponding inclined surface whereby pressure on the inside sheet of the escape panel causes a downward force on the plunger lock opposed to the spring means;
- and
- means for releasing the force of said spring means to cause said plunger lock to drop out of said recess.
