Abstract

An adapter is arranged to secure to a rotary device. The adapter includes a handle rotatable about an axis, and a coupler extending from and coaxial with the handle. The coupler is adapted to engage the rotary device via traction elements for simultaneously rotating the rotary device and the handle.

First claim

The invention claimed is:

1. A system including a rotary device and an adapter arranged to secure to the rotary device, the rotary device having a first axis and the adapter having a second axis arranged to be placed in alignment with the first axis of the rotary device, the adapter comprising:
a handle having a width greater than a width of a knob of the rotary device and rotatable about the second axis;
a coupler extending from and coaxial with the handle, and adapted to engage the knob of the rotary device, the coupler oriented coaxially with the handle along the second axis;
wherein the adapter defines a cavity defined about the second axis and extending from an engagement side into the coupler, the coupler including a rim coaxial with the second axis and surrounding at least part of the cavity;
wherein a periphery of the rim defines at least first and second traction elements generally extending radially relative to the second axis and spaced apart from one another about the rim; and
wherein the first and second traction elements each define a plurality of teeth extending coaxially relative to the second axis.

2. The system of claim 1 , wherein the handle and the coupler are formed as a monolithic single mass of material integrally and continuously formed to define the handle and the coupler.

3. The system of claim 1 , wherein the handle defines indicia arranged for indicating a rotational direction for rotating the handle.

4. The system of claim 1 , wherein the handle defines a profile forming a grip about a periphery of the handle.

5. The system of claim 1 , wherein the handle defines at least one opening arranged for receiving an attachment element.

6. The system of claim 1 , wherein the handle has a diameter greater than a diameter of the coupler.

7. The system of claim 1 , wherein the coupler has a diameter greater than a diameter of knob of the rotary device.

8. The system of claim 1 , wherein the handle has a height greater than a height of the coupler, the coupler has a height greater than a height of the knob of the rotary device, and the adapter has a height arranged at least twice the height of the knob of the rotary device.

9. The system of claim 1 , wherein the rim defines an outer diameter of the coupler, the cavity has a diameter proximate to the diameter of the knob of the rotary device, wherein a height of the rim defines a height of the coupler.

10. The system of claim 1 , wherein the handle forms an axial overhang coaxially extending at least along the rim.

11. The system of claim 1 , wherein the cavity defines a top portion extending at least into the handle or within a height of the handle.

12. The system of claim 1 , wherein a top portion of the cavity defines a profile adapted to correspond or proximate in shape to a top portion of the knob of the rotary device and adapted to facilitate traction with the top portion of the knob of the rotary device.
