Abstract

A flexible lens mount for securing a flexible lens having a first side and a second side opposite the first side. The flexible lens mount comprises a resilient member, a base member, and a fastener. The resilient member includes a first end, a second end, and a first surface adapted to abut the second side of the flexible lens. The resilient member is adapted to be flexed to form a first arc of about degrees D of about radius R. The base member includes a second surface forming a second arc which complements the first arc. The second surface is adapted to abut the first side of the flexible lens such that the flexible lens is disposed intermediate the first and second surfaces. The base member further comprises a first retaining member disposed at one end to retain the first end of the resilient member, and a second retaining member disposed at an other end to retain the second end of the resilient member. The fastener abuts either the first or second end of the resilient member to exert a force to secure the resilient member relative to the base member.

Claims

1. A flexible lens mount for a flexible lens having a first side and a second side opposite the first side, comprising:

2. The flexible lens mount of claim 1, wherein the first arc is disposed inside the second arc.

3. The flexible lens mount of claim 1, wherein the second arc is disposed inside the first arc.

4. The flexible lens mount of claim 1, wherein the force exerted is adjustable by means of the fastener.

5. The flexible lens mount of claim 1, wherein the resilient member is biased toward the base member.

6. The flexible lens mount of claim 1, wherein the arc is preformed in the resilient member.

7. The flexible lens mount of claim 1, wherein the arc is not preformed in the resilient member.

8. The flexible lens mount of claim 1, wherein the fastener is a setscrew.

9. The flexible lens mount of claim 1, wherein the first arc of degrees D ranges from about 45 to about 180 degrees.

10. The flexible lens mount of claim 1, wherein the resilient member is comprised of a stainless spring steel.

11. The flexible lens mount of claim 1, wherein the first retaining member comprises a channel.

12. The flexible lens mount of claim 1, wherein the first retaining member comprises a substantially planar surface.

13. The flexible lens mount of claim 1, wherein the second end of the resilient member comprises a leg having a first opening therethrough.

14. The flexible lens mount of claim 13, wherein the base member includes a second opening in alignment with the first opening, and the fastener is disposed through the first and second openings.

15. The flexible lens mount of claim 1, wherein the first retaining member comprises a groove disposed in the base member adapted to support the resilient member and the flexible lens.

16. A flexible lens mount for a flexible lens having a first side and a second side opposite the first side, comprising:

17. The flexible lens mount of claim 16, wherein the first arc is disposed inside the second arc.

18. The flexible lens mount of claim 16, wherein the second arc is disposed inside the first arc.

19. The flexible lens mount of claim 16, wherein the arc is preformed in the flexible retainer member.

20. The flexible lens mount of claim 16, wherein the arc is not preformed in the flexible retainer member.

21. The flexible lens mount of claim 16, wherein the flexible retainer member is comprised of a stainless spring steel.
