Abstract

A pliers includes a first member and a second member pivotally coupled to the first member. The first member and the second member each include a head and a handle having a recessed area with a non-circular cross-sectional shape and an exposed end portion adjacent the recessed area. The recessed area is bounded by a forward lip and a rear lip. The forward lip has a cross-sectional area not greater than a cross-sectional area of a portion of the handle adjacent the forward lip and opposite the recessed area. The pliers also includes a first grip positioned on the recessed area of the handle of the first member and a second grip positioned on the recessed area of the handle of the second member. The end portions of the handles are made of metal.

First claim

The invention claimed is:

1. A pliers comprising:
a first member including a first head and a first handle having a recessed area with a non-circular cross-sectional shape and an exposed end portion adjacent the recessed area, the recessed area bounded by a forward lip and a rear lip, the forward lip having a cross-sectional area not greater than a cross-sectional area of a portion of the first handle adjacent the forward lip and opposite the recessed area;
a first grip positioned on the recessed area of the first handle;
a second member pivotally coupled to the first member, the second member including a second head and a second handle having a recessed area with a non-circular cross-sectional shape and an exposed end portion adjacent the recessed area, the recessed area bounded by a forward lip and a rear lip, the forward lip having a cross-sectional area not greater than a cross-sectional area of a portion of the second handle adjacent the forward lip and opposite the recessed area; and
a second grip positioned on the recessed area of the second handle,
wherein the end portions of the first and second handles are made of metal.

2. The pliers of claim 1 , wherein the end portion of the first handle extends from the rear lip to a distal end,
wherein a cross-sectional area of the end portion of the first handle increases from the distal end to the rear lip such that the end portion of the first handle has a tapered shape,
wherein the end portion of the second handle extends from the rear lip to a distal end, and
wherein a cross-sectional area of the end portion of the second handle increases from the distal end to the rear lip such that the end portion of the second handle has a tapered shape.

3. The pliers of claim 2 , wherein the first grip and the end portion of the first handle define a generally smooth transition in a length direction of the first member, and wherein the second grip and the end portion of the second handle define a generally smooth transition in a length direction of the second member.

4. The pliers of claim 3 , wherein the first grip and the portion of the first handle adjacent the forward lip define a second generally smooth transition in the length direction of the first member, and wherein the second grip and the portion of the second handle adjacent the forward lip define a second generally smooth transition in the length direction of the second member.

5. The pliers of claim 2 , wherein the end portions of the first and second handles are configured for reaming conduit.

6. The pliers of claim 5 , wherein each of the end portions includes at least one reaming edge.

7. The pliers of claim 1 , wherein the first grip and the second grip each include a base portion made of a first material and an overlay portion made of a second material different than the first material.

8. The pliers of claim 7 , wherein the first material has a first hardness and the second material has a second hardness less than the first hardness.

9. The pliers of claim 8 , wherein the first hardness is about 80 durometer and the second hardness is about 70 durometer.

10. The pliers of claim 1 ,
wherein the first grip includes a first open end adjacent the forward lip of the first handle and a second open end adjacent the rear lip of the first handle,
wherein a cross-sectional area of the first grip decreases from the first open end to the second open end such that the first grip has a tapered shape,
wherein the second grip includes a first open end adjacent the forward lip of the second handle and a second open end adjacent the rear lip of the second handle, and
wherein a cross-sectional area of the second grip decreases from the first open end to the second open end such that the second grip has a tapered shape.

11. The pliers of claim 1 ,
wherein the second member includes an elongated aperture,
wherein the first member is pivotally coupled to the second member by a pin extending through the elongated aperture,
wherein the first head includes a first jaw, and the second head includes a second jaw,
wherein the pin is movable along the elongated aperture to adjust a spacing between the first jaw and the second jaw, and
wherein the pliers further comprises a plurality of projections disposed along the elongated aperture to selectively retain the spacing between the first jaw and the second jaw.

12. The pliers of claim 1 , wherein the first grip is non-rotatably coupled to the first handle, and wherein the second grip is non-rotatably coupled to the second handle.

13. A pliers comprising:
a first member including a first head and a first handle having a recessed area and an exposed end portion adjacent the recessed area, the recessed area bounded by a forward lip and a rear lip, the forward lip having a cross-sectional area not greater than a cross-sectional area of a portion of the first handle adjacent the forward lip and opposite the recessed area;
a first grip positioned on the recessed area of the first handle;
a second member pivotally coupled to the first member, the second member including a second head and a second handle having a recessed area with a non-circular cross-sectional shape and an exposed end portion adjacent the recessed area, the recessed area bounded by a forward lip and a rear lip, the forward lip having a cross-sectional area not greater than a cross-sectional area of a portion of the second handle adjacent the forward lip and opposite the recessed area; and
a second grip positioned on the recessed area of the second handle,
wherein the end portion of the first handle extends from the rear lip to a distal end,
wherein the end portion of the second handle extends from the rear lip to a distal end,
wherein a cross-sectional area of the end portion of the first handle increases from the distal end to the rear lip such that the end portion of the first handle has a tapered shape,
wherein a cross-sectional area of the end portion of the second handle increases from the distal end to the rear lip such that the end portion of the second handle has a tapered shape, and
wherein the end portions are made of metal.

14. The pliers of claim 13 , wherein the first grip and the end portion of the first handle define a generally smooth transition in a length direction of the first member, and wherein the second grip and the end portion of the second handle define a generally smooth transition in a length direction of second member.

15. The pliers of claim 14 , wherein the first grip and the portion of the first handle adjacent the forward lip define a second generally smooth transition in the length direction of the first member, and wherein the second grip and the portion of the second handle adjacent the forward lip define a second generally smooth transition in the length direction of the second member.

16. The pliers of claim 13 , wherein the end portions are configured for reaming conduit.

17. The pliers of claim 13 ,
wherein the first grip includes a first open end adjacent the forward lip of the first handle and a second open end adjacent the rear lip of the first handle,
wherein a cross-sectional area of the first grip decreases from the first open end to the second open end such that the first grip has a tapered shape,
wherein the second grip includes a first open end adjacent the forward lip of the second handle and a second open end adjacent the rear lip of the second handle, and
wherein a cross-sectional area of the second grip decreases from the first open end to the second open end such that the second grip has a tapered shap
