Abstract

A stabilizing chock assembly for a caster wheel or the like, including: a first stabilizing member or piece and a second stabilizing member or piece; and a clamping mechanism coupling the first stabilizing member to the second stabilizing member, the clamping mechanism operable for selectively biasing the first stabilizing member and the second stabilizing member together about a wheel; wherein the first stabilizing member and the second stabilizing member collectively define a conformal recess that is configured to selectively receive and retain a lower portion of the wheel. Optionally, the first stabilizing member and the second stabilizing member each define an arcuate ramp structure that forms a portion of the conformal recess. Optionally, the chock assembly also includes a friction surface disposed on a bottom surface of each of the first stabilizing member and the second stabilizing member.

First claim

What is claimed is:

1. A stabilizing chock assembly for a caster wheel, comprising:
a first stabilizing member and a second stabilizing member; and
a clamping mechanism coupling the first stabilizing member to the second stabilizing member, the clamping mechanism operable for selectively biasing the first stabilizing member and the second stabilizing member together about a wheel;
wherein the first stabilizing member and the second stabilizing member collectively define a conformal recess that is configured to selectively receive and retain a lower portion of the wheel;
wherein, when the first stabilizing member and the second stabilizing member are biased together about the wheel and the lower portion of the wheel is received and retained in the conformal recess collectively defined by the first stabilizing member and the second stabilizing member, the first stabilizing member and the second stabilizing member are biased downwards into contact with a surface on which the first stabilizing member and the second stabilizing member are disposed; and
wherein the clamping mechanism comprises one or more cam locks each comprising a cam lever that pivots against a cam shoulder manufactured into a surface of one of the first stabilizing member and the second stabilizing member.

2. The chock assembly of claim 1 , wherein the first stabilizing member and the second stabilizing member each comprise a half-disc-shaped structure.

3. The chock assembly of claim 1 , wherein the first stabilizing member and the second stabilizing member each define an arcuate ramp structure that forms a portion of the conformal recess.

4. The chock assembly of claim 3 , wherein each of the ramp structures comprises a friction surface disposed thereon.

5. The chock assembly of claim 3 , wherein each of the ramp structures forms a void.

6. The chock assembly of claim 1 , further comprising a friction surface disposed on a bottom surface of each of the first stabilizing member and the second stabilizing member.

7. The chock assembly of claim 1 , wherein the clamping mechanism comprises a pair of cam locks.

8. The chock assembly of claim 7 , wherein the clamping mechanism comprises a pair of parallel cam locks, with one cam lock disposed on each side of the wheel.

9. A stabilizing chock method for a caster wheel, comprising:
providing a first stabilizing member and a second stabilizing member; and
selectively biasing the first stabilizing member and the second stabilizing member together about a wheel using a clamping mechanism coupling the first stabilizing member to the second stabilizing member;
wherein the first stabilizing member and the second stabilizing member collectively define a conformal recess that is configured to selectively receive and retain a lower portion of the wheel;
wherein, when the first stabilizing member and the second stabilizing member are biased together about the wheel and the lower portion of the wheel is received and retained in the conformal recess collectively defined by the first stabilizing member and the second stabilizing member, the first stabilizing member and the second stabilizing member are biased downwards into contact with a surface on which the first stabilizing member and the second stabilizing member are disposed; and
wherein the clamping mechanism comprises one or more cam locks each comprising a cam lever that pivots against a cam shoulder manufactured into a surface of one of the first stabilizing member and the second stabilizing member.

10. The chock method of claim 9 , wherein the first stabilizing member and the second stabilizing member each comprise a half-disc-shaped structure.

11. The chock method of claim 9 , wherein the first stabilizing member and the second stabilizing member each define an arcuate ramp structure that forms a portion of the conformal recess.

12. The chock method of claim 11 , wherein each of the ramp structures comprises a friction surface disposed thereon.

13. The chock method of claim 11 , wherein each of the ramp structures forms a void.

14. The chock method of claim 9 , further comprising providing a friction surface disposed on a bottom surface of each of the first stabilizing member and the second stabilizing member.

15. The chock method of claim 9 , wherein the clamping mechanism comprises a pair of cam locks.

16. The chock method of claim 15 , wherein the clamping mechanism comprises a pair of parallel cam locks, with one cam lock disposed on each side of the wheel.

17. A stabilizing chock assembly for a caster wheel, comprising:
a first stabilizing member and a second stabilizing member; and
a clamping mechanism coupling the first stabilizing member to the second stabilizing member, the clamping mechanism operable for selectively biasing the first stabilizing member and the second stabilizing member together about a wheel;
wherein the first stabilizing member and the second stabilizing member collectively define a conformal recess that is configured to selectively receive and retain a lower portion of the wheel; and
wherein the clamping mechanism comprises one or more cam locks each comprising a cam lever that pivots against a cam shoulder manufactured into a surface of one of the first stabilizing member and the second stabilizing member.

18. The chock assembly of claim 17 , wherein the clamping mechanism comprises a pair of cam locks.

19. The chock assembly of claim 18 , wherein the clamping mechanism comprises a pair of parallel cam locks, with one cam lock disposed on each side of the wheel.
