Abstract

A clip for holding a portable electronic device comprises a retaining structure adapted to receive and retain the portable electronic device and a clip structure coupled to the retaining structure for clipping the retaining structure to something. The clip structure applies forces at two, spaced apart locations, thereby to resist rotation of the clip in use.

Claims

1. A clip for holding a portable electronic device, comprising:

a retaining structure adapted to receive and retain the portable electronic device; and

a clip structure coupled to the retaining structure for clipping the retaining structure to something, the clip structure applying forces at two, spaced apart locations, the two forces applied generally in the same direction, thereby to resist rotation of the clip in use.

2. The clip of claim 1 wherein the clip structure comprises:

a first spring member extending in a first direction, and

a second spring member coupled to the first spring member and extending in a second direction that is generally opposite to the first direction.

3. The clip of claim 2 wherein the first spring member is coupled at a first end to the retaining structure and has a contact area at a second end, and the second spring member extends in a direction from the second end towards the first end.

4. The clip of claim 3 wherein the second spring member has a contact area adjacent to the first end of the first spring member.

5. The clip of claim 2 wherein a base member is coupled to the retaining structure and to the first spring member at a first end, the first spring member has a contact area at a second end, and the second spring member extends in a direction from the second end towards the first end.

6. The clip of claim 2 wherein the first and second spring members are formed from a folded strip of metal.

7. The clip of claim 2 wherein the first and second members are formed from a folded wire.

8. The clip of claim 2 wherein the retaining structure comprises a pocket for receiving the boom of a headset.

9. The clip of claim 2 wherein the second spring member comprises one or more springs.

10. The clip of claim 1 wherein the clip structure comprises:

a first cantilever spring coupled to the retaining structure at a first end thereof and having

a contact area at the second end thereof, and

a second cantilever spring coupled to the first cantilever spring at the second end of the first cantilever spring and having a contact area located towards the first end of the first cantilever spring.

11. The clip of claim 10 wherein the first and second cantilever spring are formed from a folded strip of metal.

12. The clip of claim 10 wherein the first and second cantilever spring are formed from a folded wire.

13. The clip of claim 10 wherein the retaining structure comprises a pocket for receiving the boom of a headset.

14. The clip of claim 10 wherein the second cantilever spring comprises two or more strips of spring material.

15. The clip of claim 1 wherein the clip structure comprises:

a base member coupled to the retaining structure and to a first cantilever spring at a first end, the first cantilever spring having a contact area at the second end thereof, and

a second cantilever spring coupled to the first cantilever spring at the second end of the first cantilever spring and having a contact area located towards the first end of the first cantilever spring.

16. The clip of claim 15 wherein the first and second cantilever springs are formed from a folded strip of metal.

17. The clip of claim 15 wherein the first and second cantilever springs are formed from a folded wire.

18. The clip of claim 15 wherein the retaining structure comprises a pocket for receiving the boom of a headset.

19. The clip of claim 15 wherein the second cantilever spring comprises two or more strips of spring material.

20. The clip of claim 1 further comprising a support member and the forces are a function of the distance between the clip structure and support member.

21. The clip of claim 20 wherein a ratio between the forces is substantially constant for a range of equivalent distances between the clip structure and support member.

22. The clip of claim 21, wherein the forces are substantially equal.
