ABSTRACT:
The device of the present invention can be attached to a round door knob to make the door knob easy to turn by pushing a levering handle. The handle and clamp are in two pieces that are fastened together to form a single door knob clamp and handle. The two pieces are adjustable relative to each other so the clamp can be opened and closed allowing attachment to a variety of different sized and different shaped door knobs. Easy to install and easy to remove, the invention is designed to remain on the door knob once it has been installed, but it can be removed if desired or necessary. A child cord is affixed through an aperture in the free end of the handle making it easy for a child to open a door.
