Abstract
A non-metallic adapter provided to facilitate the rotation of a doorknob is formed with a cap adapted to receive a doorknob. A lever extends outwardly from the cap. The lever is formed with an internal cavity provided with a plurality of reinforcing members separating the cavity into a plurality of substantially isolated reinforced regions.
Claims17
A non-metallic adapter facilitating rotation of a door knob having a supporting shaft, said adapter comprising:
- a cap;
- the cap being adapted to receive the knob;
- a lever extending outwardly from the cap and transversely to an axis thereof;
- and
- a pressure ring adapted to pass over and around the supporting shaft, the cap adapted to be frictionally attached to the knob by axial force between the ring and said cap producing required frictional attachment,
- wherein the lever is formed with an internal cavity provided with a plurality of reinforcing members subdividing the internal cavity into a plurality of substantially isolated reinforced regions.
The adapter according to claim 8, wherein a multiplicity of the transverse reinforcing members extends between the utility aperture and the respective longitudinal walls.
A non-metallic adapter facilitating rotation of a door knob having a supporting shaft, said adapter comprising:
- a cap;
- the cap being adapted to receive the knob;
- a handle extending outwardly from the cap;
- a pressure ring adapted to pass over and around the supporting shaft, the cap adapted to be frictionally attached to the knob by axial force between the ring and the cap producing a required frictional engagement;
- the pressure ring being formed having substantially C-shaped configuration with inner, outer walls and an inner space formed therebetween;
- and reinforced wherein a plurality of stiffening members extend within said inner space between said inner and outer walls separating the inner space of the pressure ring into a plurality of substantially isolated areas.
