ABSTRACT:
A drawer type emergency escape is constituted by a stowage box adapted to be attached to a support, a slidable frame adapted to be slidably extended out of and retracted into the stowage box, a telescopically extensible escape means attached to the slidable frame to be received into and extended out of the frame, and a shift mechanism for pulling the slidable frame out of the stowage box as the escape is employed. The shift mechanism includes a drive arm connected to a shift handle, a slide shift link, a connection link connecting the drive arm to the slide shift link and an extensible tong means disposed between the slide shift link and slidable frame for extending and retracting the slidable frame out of and into the stowage box.
