A power door opener including an actuator having a housing with an electrically powered actuator shaft that can be extended from a closed to an extended position. In one embodiment, a movable push plate is affixed to the actuator shaft and a fixed push plate is fixed in its position with respect to the housing. In the closed position of the actuator shaft, the fixed and movable push plates are aligned to form a combined edge for insertion into the space between a door and door jamb. The actuator shaft extends to move the movable push plate apart from the fixed push plate to spread the space and release the door from the door jamb. Alternatively, a double ended power door opener is located between opposite door jambs and the extending of the actuator shaft forces the door jambs apart to release the door from the door jamb.
A power door opener comprising a power actuator having a housing with a actuator shaft movable between a closed position and an extended position wherein the actuator shaft is extended outwardly from the housing and an electric motor adapted to move the actuator shaft between its closed and extended positions, a fixed push plate immovably affixed to the power actuator, the fixed push plate having a fixed tapered pry member extending outwardly therefrom, and a movable push plate affixed to the actuator shaft, the movable push plate having a movable tapered pry member extending outwardly therefrom, wherein the fixed pry member and the movable pry member are aligned in close proximity to form a common edge when the actuator shaft is in its closed position and the common edge tapers inwardly in the outer direction so as to be forcible into a linear opening.
A double ended power door opener comprising a power actuator having a front side and a rear side, a actuator shaft extendable from the front side of the power actuator, the actuator shaft being movable between a closed position and an extended position wherein the actuator shaft is extended outwardly and an electric motor adapted to move the actuator shaft between its closed and extended positions, a movable push plate affixed to the actuator shaft, an extension extending outwardly from the rear side of the actuator, the extension having a distal end wherein the distal end of the extension and movable push plate are moved apart by the outwardly extending movement of the actuator shaft.
