ABSTRACT:
A lever adapter for use with door knobs for aiding arthritic patients in rotating the door knob. The lever adapter is attached to the door knob by a concave, arcuate member having a layer of adhesive. Pulling upon on or pushing down on the lever adapter will cause the simultaneous rotation of the door knob in one direction or the other, whereby linear motion is converted to rotary, in order to obviate the pain and discomfort associated with the turning of a door knob by arthritic persons.
