Abstract

Disclosed is a tool, such as pliers, with handle offsets and stop features. In an embodiment, the tool has a minimum of about 0.50 inches of clearance between handles in an area where a user's index finger contacts the handles. This is accomplished by offsetting upper and lower handles of the tool. For example, the lower handle may be offset about 1.10 inches from a pivot point between the handles. Similarly, an end of the upper handle may be offset by about 1.150 inches from the pivot point when jaws of the tool are adjusted to a closed position.

First claim

What is claimed is:

1. A tool comprising:
a first portion having a first jaw portion and a first handle portion;
a second portion having a second jaw portion, a second handle portion, and an elongated slot disposed in the second portion between the second jaw portion and the second handle portion, the second portion is pivotally coupled to the first portion at a pivot point that is movable along the elongated slot, wherein a first outer edge of the first handle portion is offset from the pivot point by a first length, and a second outer edge of the second handle portion is offset from the pivot point by a second length; and
teeth disposed on the second portion proximal to or extending into the elongated slot,
wherein the teeth are spaced with respect to one another at about 0.098 inches, and
wherein when the pivot point is moved along the elongated slot such that a distance between the first and second jaw portions is at a maximum opening, the first and second lengths provide at least about 0.50 inches of clearance between the first and second handle portions at a gripping area of the first and second handle portions.

2. The tool of claim 1 , wherein the first length is about 1.10 inches.

3. The tool of claim 1 , wherein the second length is about 1.15 inches.

4. The tool of claim 1 , wherein the maximum opening between the first and second jaw portions is about 2.24 inches.

5. The tool of claim 1 , wherein the maximum opening between the first and second jaw portions is about 2.28 inches.

6. The tool of claim 1 , further comprising a pawl having pawl teeth, wherein the pawl is disposed adjacent to a first side of the first portion and extends into an aperture in the first portion, and the pawl teeth are adapted to engage the teeth disposed on the second portion.

7. The tool of claim 6 , further comprising a button disposed adjacent to a second side of the first portion.

8. The tool of claim 7 , further comprising a bias member disposed between the button and the second side of the first portion, wherein the bias member is adapted to bias the button outwardly away from the second side and the pawl teeth into engagement with the teeth disposed on the second portion.

9. The tool of claim 8 , wherein depression of the button against a bias force of the bias member causes the pawl teeth to disengage from the teeth disposed on the second portion.

10. The tool of claim 1 , wherein the elongated slot is formed by first and second side portions extending between the second handle portion and the second jaw portion.

11. The tool of claim 10 , wherein the teeth are disposed on the first and second side portions.

12. A tool comprising:
a first portion having a first jaw portion and a first handle portion;
a second portion having a second jaw portion, a second handle portion, and an elongated slot disposed in the second portion between the second jaw portion and the second handle portion, the second portion is pivotally coupled to the first portion at a pivot point that is movable along the elongated slot, wherein a first outer edge of the first handle portion is offset from the pivot point by a first length, and a second outer edge of the second handle portion is offset from the pivot point by a second length; and
teeth disposed on the second portion proximal to or extending into the elongated slot,
wherein the teeth are spaced with respect to one another at about 0.066 inches, and
wherein when the pivot point is moved along the elongated slot such that a distance between the first and second jaw portions is at a maximum opening, the first and second lengths provide at least about 0.50 inches of clearance between the first and second handle portions at a gripping area of the first and second handle portions.

13. The tool of claim 12 , wherein the maximum opening between the first and second jaw portions is about 2.24 inches.

14. The tool of claim 12 , wherein the maximum opening between the first and second jaw portions is about 2.28 inches.

15. The tool of claim 12 , wherein the first length is about 1.10 inches.

16. The tool of claim 12 , wherein the second length is about 1.15 inches.

17. The tool of claim 12 , wherein the elongated slot is formed by first and second side portions extending between the second handle portion and the second jaw portion, and the teeth are disposed on at least one of the first and second side portions and extend inwardly into the elongated slot.

18. The tool of claim 12 , further comprising a pawl having pawl teeth, wherein the pawl is disposed adjacent to a first side of the first portion and extends into an aperture in the first portion, and the pawl teeth are adapted to engage the teeth.

19. The tool of claim 18 , further comprising a button disposed adjacent to a second side of the first portion.

20. The tool of claim 19 , further comprising a bias member disposed between the button and the second side of the first portion, wherein the bias member is adapted to bias the button outwardly away from the second side and the pawl teeth into engagement with the teeth disposed on the second portion, and wherein depression of the button against a bias force of the bias member causes the pawl teeth to disengage from the teeth.
