ABSTRACT:
A door knob handle attachment for securement to conventional round door knobs is formed by two mating semicircular shell members. An elongated lever extends from one shell member to enable disabled individuals to more easily open doors. The shell members each have an undercut recess lined with a resilient material for frictional engagement around a door knob. The shell members may be pivotally connected at first aligned ends and secured together at opposite aligned ends to form a circular collar. In a second embodiment, radially movable clamp members are provided in the undercut recess of each of the shell members for engagement with a conventional door knob.
