Abstract

A clean toggle clamp is configured to operate without creating excessive debris. The clean toggle clamp includes a base; an arm rotationally coupled to the base via a first bearing isolated rod; a clamping element; a handle is rotationally coupled to the arm via a second bearing isolated rod. The handle includes a revolving latching pin and a linkage rotationally coupled on a first end to the handle via at least one third bearing isolated rod and on a second end to the base via a fourth bearing isolated rod. The toggle clamp includes a secondary latch rotationally coupled to the base and configured to engage the revolving latching pin to inhibit movement of the handle and arm. The handle, arm, linkage and secondary latch are configured to rotate without a frictional sliding of any of surface of the arm, the handle, the linkage or the base.

First claim

What is claimed is:

1. A toggle clamp comprising:
a base configured to couple to a surface;
an arm rotationally coupled to the base via a first bearing isolated rod, the arm comprising a clamping element;
a handle rotationally coupled to the arm via a second bearing isolated rod, the handle comprising a revolving latching pin;
a linkage rotationally coupled on a first end to the handle via a third bearing isolated rod and on a second end to the base via a fourth bearing isolated rod; and
a secondary latch rotationally coupled to the base and configured to engage the revolving latching pin to inhibit movement of the handle and arm,
wherein each of the bearing isolated rods comprises a rod coupled to one or more bearings, and wherein the bearing isolated rods are configured to enable the handle, the arm, and the linkage to rotate without a frictional sliding of any surface of the arm, the handle, the linkage, or the base.

2. The toggle clamp according to claim 1 , wherein the clamping element comprises one of:
a contact bolt;
a spring-loaded tip;
a contact disc; or
a clamp roller.

3. The toggle clamp according to claim 1 , wherein the clamping element includes a captive o-ring.

4. The toggle clamp according to claim 1 , wherein the secondary latch is spring-loaded and configured to rotate within a limited arc and wherein the revolving latching pin is rotationally coupled to the handle via a bearing interface.

5. The toggle clamp according to claim 1 , wherein the toggle clamp is configured to be normally closed, further comprising one or more springs configured to maintain the toggle clamp in a restrained position.

6. The toggle clamp according to claim 1 , further comprising a hard stop configured to limit a forward clamping motion of the toggle clamp.

7. A toggle clamp comprising:
a base configured to couple to a surface;
an arm rotationally coupled to the base via a first bearing isolated rod, the arm comprising a clamping element;
a handle rotationally coupled to the arm via a second bearing isolated rod, the handle comprising a revolving latching pin;
a linkage rotationally coupled on a first end to the handle via a third bearing isolated rod and on a second end to the base via a fourth bearing isolated rod;
a secondary latch rotationally coupled to the base and configured to engage the revolving latching pin to inhibit movement of the handle and arm; and
a magnetic element configured to maintain the toggle clamp in an un-clamped position;
wherein the handle, arm and linkage are configured to rotate without a frictional sliding of any surface of the arm, the handle, the linkage or the base.

8. A toggle clamp comprising:
a base comprising a bottom surface, a first lateral edge, and a second lateral edge;
an arm rotationally coupled to the base between the first lateral edge and the second lateral edge, the arm comprising a clamping element;
a handle rotationally coupled to the arm; and
a secondary latch rotationally coupled to the base between an interior surface of the first lateral edge and an interior surface of the second lateral edge, the secondary latch configured to inhibit motion of at least one of the arm or the handle,
wherein the handle and the arm are configured to rotate without a frictional sliding of any surface of the arm, the handle, or the base with another surface of the arm, the handle, or the base.

9. The toggle clamp according to claim 8 , wherein the clamping element comprises one of:
a contact bolt;
a spring-loaded tip;
a contact disc; or
a clamp roller.

10. The toggle clamp according to claim 8 , wherein the clamping element includes a captive o-ring.

11. The toggle clamp according to claim 8 , wherein the secondary latch is spring-loaded and configured to engage a revolving latching pin that is rotationally coupled to the handle via a bearing interface.

12. The toggle clamp according to claim 8 , wherein the toggle clamp is configured to be normally closed, further comprising one or more springs configured to maintain the toggle clamp in a restrained position.

13. The toggle clamp according to claim 8 , further comprising a hard stop configured to limit a forward clamping motion of the toggle clamp.

14. A toggle clamp comprising:
a base;
an arm rotationally coupled to the base, the arm comprising a clamping element;
a handle rotationally coupled to the arm;
a secondary latch configured to inhibit motion of at least one of the arm or the handle; and
a magnetic element configured to maintain the toggle clamp in an un-clamped position;
wherein the handle and the arm are configured to rotate without a frictional sliding of any surface of the arm, the handle, or the base with another surface of the arm, the handle, or the base.

15. A system comprising:
a number of toggle clamps, wherein at least one toggle clamp comprises:
a base;
an arm rotationally coupled to the base, the arm comprising a clamping element;
a handle rotationally coupled to the arm; and
a secondary latch configured to inhibit motion of at least one of the arm or the handle, wherein surfaces of the handle and the arm are separated from each other and from surfaces of the base such that the handle and the arm are able to rotate without a frictional sliding of any of the surfaces of the arm, the handle, or the base with another surface of the arm, the handle, or the base.

16. The system according to claim 15 , wherein the clamping element comprises one of:
a contact bolt;
a spring-loaded tip and a hard stop configured to limit a forward clamping motion of the toggle clamp;
a contact disc; or
a clamp roller.

17. The system according to claim 15 , wherein the clamping element includes a captive o-ring.

18. The system according to claim 15 , wherein the secondary latch is spring-loaded and configured to engage a revolving latching pin that is rotationally coupled to the handle via a bearing interface.

19. The system according to claim 15 , wherein the at least one toggle clamp is configured to be normally closed and further comprises one or more springs configured to maintain the at least one toggle clamp in a restrained position.

20. A system comprising:
a number of toggle clamps, wherein at least one toggle clamp comprises:
a base;
an arm rotationally coupled to the base, the arm comprising a clamping element;
