ABSTRACT:
A door knob lever is described, for use primarily by disabled persons, as including a rotatable hook at one end thereof for hooking around the base of a common door knob. A right angle or arcuate shaped bracket is also included, with the rotation of the hook taking place with respect to the bracket. The other end of the lever provides a handle for enabling the gripping of the lever, so that the user grips the handle of the lever, swings it to cause the hook to encircle the door knob at its base, rotates the bracket to engage the door knob gripping surface and then rotates the lever to cause the door knob to rotate.
