Abstract

Tools including a jaw portion, a hinge portion, and a handle portion are provided. The jaw-portion may include a pair of jaws. The hinge portion may generally be configured to allow each jaw of the pair of jaws to pivot between open and closed positions relative to each other and form an aperture adjacent a tip of each of the pair of jaws when the jaws are in the closed position. The handle portion may be located on the opposite side of the hinge portion to the jaw portion to allow for opening and closing of the pair of jaws.

First claim

What we claim is:

1. A method of removing a staple, comprising:
(i) providing a tool comprising:
a jaw portion comprising a pair of jaws;
a hinge portion configured to allow each jaw of the pair of jaws to pivot between an open position and a closed position relative to each other and to form an aperture adjacent a tip of each jaw of the pair of jaws when the pair of jaws are in the closed position;
a handle portion on an opposite side of the hinge portion from the jaw portion to allow for the pair of jaws to pivot between the open position and the closed position; and
at least one projection extending outwardly from a face of each jaw of the pair of jaws at a position adjacent the tip of each jaw of the pair of jaws such that the at least one projection slants inwardly toward an axis of opening symmetry of the pair of jaws;

(ii) positioning the tool into a crook of a fence staple by inserting the tip of each jaw into the crook of the fence staple; and
(iii) removing the fence staple from a support structure with the tool,
wherein positioning the tool into the crook of the fence staple further comprises contacting the support structure with a top surface of the at least one projection such that the at least one projection acts as a fulcrum for applying a levering force to the fence staple grasped by the pair of jaws when in the closed position, wherein the top surface is distal from the face of each jaw from which the at least one projection extends,
wherein the top surface of the at least one projection when the pair of jaws are in the closed position is within an inclusive range of 1 to 10 mm of a tangential line at the tip of each of the pair of jaws, the tangential line being substantially perpendicular to the axis of opening symmetry as the pair of jaws open outwardly into the open position.

2. The method as claimed in claim 1 , wherein the top surface of the at least one projection comprises a gripping or anti-slip surface.

3. The method as claimed in claim 1 , wherein a cross-sectional area of the top surface of the at least one projection is at least 20 mm 2 .

4. The method of claim 1 , wherein a shape of the at least one projection is selected from the group consisting of: cylindrical, conical, frustoconical, pyramidal, cuboid, and a parallelepiped.

5. The method of claim 1 , wherein the at least one projection extends a minimum of 7.5 mm from the face of each jaw of the pair of jaws.

6. The method of claim 1 , wherein the at least one projection extends a minimum of 12.5 mm from a center plane of each jaw of the pair of jaws.

7. The method of claim 1 , wherein the at least one projection is integrally formed into each jaw of the pair of jaws.

8. The method of claim 1 , wherein a distance of closest approach between a primary load-bearing area of the at least one projection on each jaw when the pair of jaws is in the closed position is within an inclusive range of 8 to 35 mm.

9. The method of claim 1 , wherein the aperture is substantially circular.

10. The method of claim 1 , wherein the aperture accommodates a wire with a diameter in a range of 1.6 mm to 4.5 mm.

11. The method of claim 1 , wherein the hinge portion comprises a single pivot connecting the pair of jaws.

12. The method of claim 1 , wherein the hinge portion comprises a multiple pivot point hinge arrangement with mechanical linkages connecting the pair of jaws.

13. The method of claim 1 , wherein the jaw portion is integral with the handle portion.

14. The method of claim 1 , wherein the handle portion comprises one or more of the following features: cushioning, gripping modifications, moulded portions for accommodating fingers, telescoping closure limiting features which set a minimum distance of approach when the pair of jaws is in the closed position.

15. The method of claim 1 , wherein the jaw portion further comprises a wire cutting feature.

16. The method of claim 1 , wherein the jaw portion further comprises a cable crimping feature.

17. The method of claim 1 , wherein the tip of at least one jaw of the pair of jaws is fine enough to insert and fit at least half-way under the crook of a 2.5 mm gauge fencing staple.

18. The method of claim 1 , wherein the tip of at least one jaw of the pair of jaws is fine enough to insert and fit at least half-way under the crook of a 4 mm gauge fencing staple.

19. The method of claim 1 , wherein the tip of at least one jaw of the pair of jaws is tapered towards an end of the tip.

20. The method of claim 1 , wherein the tip of at least one jaw of the pair of jaws is less than 1.75 mm across.

21. The method of claim 1 , wherein a cross sectional area of the tip of at least one jaw of the pair of jaws is less than 2 mm 2 .

22. The method of claim 1 , wherein the jaw portion comprises metal.

23. The method of claim 22 , wherein the metal is a stainless steel or an alloy steel.
