发明名称 Low force egress and safety apparatus for subterranean window wells
摘要 An apparatus for providing improved egress and greater safety for subterranean window wells. The apparatus has relatively low lifting force to allow people to escape fires and earthquake damaged buildings through egress windows. The apparatus can include mounts which are U-shaped and fit over opposing sides of the window well wall and are connected thereto. The mounts may have pivots which connect to an operator that applies upward force upon a grate assembly that covers the window well. The mounts and grate are hinged to pivot and allow the grate to be opened when needed. The operator has swivel and ball connections and an adjustable outboard connector.
