Abstract

One embodiment of a seal removal tool may include a handle, a seal grasping member, and a biasing member. The handle may have an end with a curved surface to roll back a seal. The seal grasping member may be adapted to move from an open extended position into a closed position in order to grasp and secure a seal. The biasing member may bias the seal grasping member towards the closed position.

Claims (41)

1. A seal removal tool comprising:

a handle; and

a seal grasping member moveably attached to the handle configured to move from a first position relative to the handle to a second position farther away from the handle;

a moveable member fixedly attached to the seal grasping member and moveably disposed relative to the handle; and

a biasing member disposed against the moveable member biasing the seal grasping member in a direction relative to the handle.

2. The seal removal tool of claim 1 wherein the moveable member moveably extends through a hole in the handle.

3. The seal removal tool of claim 1 wherein the moveable member comprises a bolt and the biasing member is disposed against a cap of the bolt.

4. The seal removal tool of claim 1 wherein the handle comprises a curved surface at a first end of the handle for rolling back a seal.

5. The seal removal tool of claim 4 wherein the curved surface comprises a semi-circle having a radius in a range of 1/16 of an inch to 1 inch.

6. The seal removal tool of claim 4 wherein the handle has a second end for being grasped and rotated by a user to roll back the seal.

7. The seal removal tool of claim 1 wherein the seal grasping member comprises a hook.

8. The seal removal tool of claim 7 wherein the hook is angled inwardly towards a linear portion of the seal grasping member from which the hook extends.

9. The seal removal tool of claim 1 wherein a first end of the handle extends over and beyond an end of the seal grasping member.

10. The seal removal tool of claim 1 wherein the biasing member comprises a spring.

11. The seal removal tool of claim 1 wherein the biasing member extends between the handle and the moveable member.

12. The seal removal tool of claim 1 wherein the biasing member biases the seal grasping member towards the first position.

13. The seal removal tool of claim 1 wherein one end of the seal grasping member is welded to handle.

14. The seal removal tool of claim 1 wherein the moveable member is disposed substantially perpendicular to the handle.

15. The seal removal tool of claim 6 wherein during removal of the seal the handle is rotated from a first angle relative to a sealed portion of the seal in a range of 0 to 45 degrees to a second angle in which the handle is substantially perpendicular to the sealed portion of the seal.

16. The seal removal tool of claim 1 wherein during removal of a seal the seal grasping member is configured to allow the seal to be slipped between the seal grasping member and the handle when the seal grasping member is disposed in the second position.

17. The seal removal tool of claim 1 wherein during removal of a seal the seal grasping member is configured to hold the seal between the seal grasping member and the handle when the seal grasping member is disposed in the first position.

18. A method for removing a seal comprising:

providing a seal removal tool comprising a handle, a seal grasping member moveably attached to the handle, a moveable member fixedly attached to the seal grasping member and moveably disposed relative to the handle, and a biasing member disposed against the moveable member biasing the seal grasping member in a direction relative to the handle;

disposing the seal removal tool, with the seal grasping member disposed in a position relative to the handle, so that a seal is disposed between the handle and the seal grasping member; and

moving the seal grasping member to another position closer to the handle to secure the seal between the handle and the seal grasping member.

19. The method of claim 18 wherein the moveable member is moveably extended through a hole in the handle.

20. The method of claim 18 wherein the moveable member comprises a bolt and the biasing member is disposed against a cap of the bolt.

21. The method of claim 18 wherein the handle comprises a curved surface at a first end of the handle, and further comprising disposing the curved surface of the handle against the seal.

22. The method of claim 21 wherein the curved surface comprises a semi-circle having a radius in a range of 1/16 of an inch to 1 inch.

23. The method of claim 21 wherein the handle has a second end, and further comprising rotating the second end to roll back the seal.

24. The method of claim 18 wherein the seal grasping member comprises a hook.

25. The method of claim 24 wherein the hook is angled inwardly towards a linear portion of the seal grasping member from which the hook extends.

26. The method of claim 18 wherein a first end of the handle extends over and beyond an end of the seal grasping member.

27. The method of claim 18 wherein the biasing member comprises a spring.

28. The method of claim 18 wherein the biasing member extends between the handle and the moveable member.

29. The method of claim 18 wherein the biasing member biases the seal grasping member towards the closer position, and further comprising a user pushing the moveable member towards the handle during the disposing step to move the seal grasping member into the position, and the user releasing the moveable member during the moving step so that the biasing member moves the seal grasping member towards the closer position.

30. The method of claim 18 wherein one end of the seal grasping member is welded to the handle.

31. The method of claim 18 wherein the moveable member is disposed substantially perpendicular to the handle.

32. The method of claim 23 wherein the handle is rotated from a first angle relative to a sealed portion of the seal in a range of 0 to 45 degrees to a second angle in which the handle is substantially perpendicular to the sealed portion of the seal.

33. The method of claim 18 wherein the seal is attached to an aircraft door.

34. The method of claim 18 further comprising rotating the handle to remove the seal and removing a fastener disposed under the seal.
