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.

Claims

1. A clamp apparatus comprising:

a body;

a first actuator;

a second actuator;

a first gear set operatively coupled to the first actuator and a second gear set operatively coupled to the second actuator, wherein the first gear set is configured to operatively engage the second gear set;

a first movable gripper operatively coupled to the body;

a second movable gripper operatively coupled to the body;

a third gear set operatively coupled to the first movable gripper and a fourth gear set operatively coupled to the second movable gripper, wherein the third gear set operatively engages the fourth gear set; and

at least one leaf spring configured to operatively engage with the third gear set and the fourth gear set, wherein the at least one leaf spring is configured to urge the first movable gripper and the second movable gripper toward a clamped position.

2. The clamp apparatus of claim 1, wherein the first gear set and the second gear set are rotatably coupled to the body.

3. The clamp apparatus of claim 1, wherein the third gear set and the fourth gear set are rotatably coupled to the body.

4. The clamp apparatus of claim 1, wherein the first gear set and the third gear set are rotatably coupled to the body and share an axis of rotation.

5. The clamp apparatus of claim 1, wherein the third gear set and the fourth gear set are rotatably coupled to the body and share an axis of rotation.

6. The clamp apparatus of claim 1, wherein the first gear set and the second gear set form a first locking assembly comprising:

a first hook coupled to the first gear set;

a second hook coupled to the second gear set;

a first catch coupled to the third gear set, wherein the first hook locks into place within the first catch when the first movable gripper and the second movable gripper are in the clamped position; and

a second catch coupled to the fourth gear set, wherein the second hook locks into place within the second catch when the first movable gripper and the second movable gripper are in the clamped position.

7. The clamp apparatus of claim 6, wherein the first catch and the first hook and the second catch and the second hook are configured to permit rotational movements of the first actuator and the second actuator in advance of subsequent rotational movements of the first movable gripper and the second movable gripper.

8. The clamp apparatus of claim 7, wherein the rotational movements of the first actuator and the second actuator are configured to perform an unlocking function, permitting rotational movements of the first movable gripper and the second movable gripper.

9. The clamp apparatus of claim 1, wherein the first movable gripper and the second movable gripper have interdigitated fingers when the at least one leaf spring is subject to a maximum allowable deformation.

10. The clamp apparatus of claim 1, wherein the at least one leaf spring is configured to bias the first movable gripper and the second movable gripper toward one another.

11. The clamp apparatus of claim 1, wherein the first movable and the second movable gripper are configured to close onto a pole.

12. The clamp apparatus of claim 1, wherein the at least one leaf spring is under a preload tension.

13. The clamp apparatus of claim 1, wherein the first actuator and the second actuator are paddles.

14. The clamp apparatus of claim 1, wherein the first actuator and the second actuator are actuatable.

15. The clamp apparatus of claim 1, wherein the first movable gripper and the second movable gripper are rubber.

16. The clamp apparatus of claim 1, wherein the first actuator and the second actuator are independently operatively attached to the body via pins.

17. The clamp apparatus of claim 1, wherein the first actuator and the second actuator are independently hinged to the body.

18. The clamp apparatus of claim 1, wherein axes about which the first actuator and the second actuator are hinged to the body are parallel.

19. The clamp apparatus of claim 1, wherein the first movable gripper and the second movable gripper have facing inside surfaces that are approximately concave.

20. The clamp apparatus of claim 1, wherein the clamp apparatus is configured to couple a medical device to a support pole.

21. The clamp apparatus of claim 1, wherein the clamp apparatus is configured to couple a medical device to an IV pole.

22. The clamp apparatus of claim 21, wherein the medical device is a monitor comprising a tablet computer.
