WINDOW PROPELLING SYSTEM

摘要

A window propelling system for rapidly opening a window or door. The window propelling system is designed for installation with existing units and preferably includes a lift assembly (58), a cylinder assembly (60), a hammer assembly (62), a firing assembly (64) and a secondary triggering assembly (66). The lift assembly includes a lift cable (42) attached at opposite ends to the window or door. The cylinder assembly (60) includes a piston cable (82) which drives the lift cable (42) during emergency opening. The cylinder assembly (60) in turn, is actuated by the firing assembly (64) in response to operation of the hammer assembly (62). The hammer assembly (62) is released by either an interior trigger (40, 48) or the secondary trigger assembly (66).
