Abstract
A window well cover jack is disclosed. The window well cover jack has three arms: a base arm, a support arm and an actuator handle, all connected to aid in the lifting of a window well cover and to allow egress. In one embodiment, the jack is lockable in a stowed position. It is also possible to add a spring assist to aid in the lifting of a window well cover. Ideally, the window well cover jack is also lockable in a deployed position to aid in holding an ajar window well cover so as to facilitate escape. A simple link, which is easily broken by emergency crews with the proper tools but secure against intruders without said tools, connects the window well cover jack to a window well cover.
