ABSTRACT:
A portable apparatus for manipulating a hinged member, comprising a telescoping handle and a jaw having upper and lower jaw members pivotally connected to one end of the handle. The upper and lower jaw members are oriented parallel to each other and are spaced apart for receiving the hinged member therebetween. The inner surfaces of the upper and lower jaw members are shaped for conforming to the shape of the hinged member. First and second resilient members are connected to the upper and lower jaw members, respectively, and to the handle for biasing the jaw member toward a position wherein the jaw is aligned with an axis of the handle. The biasing action of the resilient members provides a clamping action to prevent the hinged member from being dislodged from the jaws and also provides a torque in both a clockwise and counterclockwise direction, depending on the orientation of the hinged member, for facilitating the initiation of the raising or lowering operation.
