Abstract

A clamp apparatus is disclosed that includes a body, first and second actuators, first, second, third and fourth gear sets, first and second movable grippers, and at least one leaf spring. The first gear set is coupled to the first actuator and the second gear set is coupled to the second actuator. The first gear set engages the second gear set. The first and second movable grippers are each operatively coupled to the body. The third gear set is coupled to the first movable gripper and the fourth gear set is coupled to the second movable gripper. The third gear set operatively engages the fourth gear set. The leaf spring engages with the third gear set and the fourth gear set to urge the first movable gripper and the second movable gripper toward a clamped position.

First claim

What is claimed is:

1. A clamp assembly comprising:
a first jawed component including a first jaw shaped end;
a second jawed component including a second jaw shaped end, the first jawed component being coupled to one another;
at least one bias member engaged by the first jawed component and the second jawed component, the at least one bias member biasing the first jawed component and the second jawed component to spread apart from one another, wherein the first and second jawed components include interdigitating geared ends opposing the first and second jawed ends; and
an actuator coupled to the first jawed component and the second jawed component, actuation of the actuator causing the first and second jawed components to move from a first position to a second position, the first jaw shaped end and the second jaw shaped end being closer to one another in the second position than in the first position.

2. The clamp assembly of claim 1 , wherein:
the first jawed component includes a first pocket;
the second jawed component includes a second pocket; and
the at least one bias member is secured within the first pocket and the second pocket.

3. The clamp assembly of claim 1 , further comprising:
a frame, the first and second jawed components being pivotally retained in the frame.

4. The clamp assembly of claim 3 , wherein the frame includes a top surface, a bottom surface, and a back surface, the back surface connecting the top surface and the bottom surface.

5. The clamp assembly of claim 3 , further comprising:
a first connector pivotally coupling the first jawed component to the frame; and
a second connector pivotally coupling the second jawed component to the frame.

6. The clamp assembly of claim 5 , wherein:
the first jawed component is pivotable around a first axis of rotation extending lengthwise through the first connector; and
the second jawed component is pivotable around a second axis of rotation extending lengthwise through the second connector.

7. The clamp assembly of claim 6 , wherein the first connector and the second connector control deformation of the at least one bias member.

8. The clamp assembly of claim 1 , wherein the actuator further comprises a paddled end.

9. The clamp assembly of claim 8 , wherein the actuator further comprises a pairing member.

10. The clamp assembly of claim 9 , wherein the first and second jawed components each include a section configured to at least partially receive the pairing member of the actuator.

11. The clamp assembly of claim 8 , wherein the paddled end is distal to the first and second jawed components.

12. The clamp assembly of claim 2 , wherein the at least one bias member is partially compressed in order to be placed in the first and second pockets.

13. The clamp assembly of claim 3 , wherein the at least one bias member is a spring steel sheet.

14. The clamp assembly of claim 3 , wherein the at least one bias member is a planar leaf spring.

15. The clamp assembly of claim 3 , wherein the at least one bias member includes an edge that extends from an interior of the frame, a force on the edge causing deflection of the at least one bias member.

16. The clamp assembly of claim 15 , wherein the deflection is increased in the second position.

17. The clamp assembly of claim 3 , further comprising:
a latch engaged to the back surface of the frame, the latch being receivable by a socket.

18. The clamp assembly of claim 17 , wherein the latch comprises a flap portion and a lever portion, the frame further comprises a connecting rim between the top surface and the back surface of the frame, the connecting rim including a groove, the lever portion resting on the groove.

19. The clamp assembly of claim 18 , wherein forcing the lever portion away from the groove causes the flap portion to pivot toward the interior of the frame to release one or more pairing members from the socket.
