Abstract
A combination slide-type fire door and hinge-type pass door for allowing personnel to exit through the pass door when the fire door is closed. The fire door is provided with an opening therethrough substantially the same size and shape as the pass door. One side edge of the pass door is hinged to the fire door adjacent one side edge of the opening through the fire door whereby the pass door can be moved between a closed position in which exit through the opening is prevented and an opened position in which exit through the opening is allowed. A peg member and a latch member are attached to the other side of the pass door. The peg member has a distal end spaced outwardly from the side edge of the pass door and arranged substantially perpendicular to the face surface of the pass door. The fire door has an aperture for receiving the distal end portion of the peg member when the pass door is closed. The fire door has a cavity for receiving a portion of the latch member when the pass door is closed. The opening through the fire door extends through the bottom edge of the fire door so that personnel can pass through the opening without having to step over any portion of the fire door.
