Abstract

Pliers with receiving surfaces formed in the handles of the pliers so as to increase the contact surface area between the pliers and the work piece. The pliers grip the work piece at the jaws of the pliers and at the receiving surfaces to increase the contact area between the tool and the work piece as compared to conventional adjustable pliers.

First claim

What is claimed is:

1. Pliers adapted to engage a work piece, the pliers comprising:
a first plier half including a first handle, and a first jaw extending from the first handle and including first jaw teeth;
a second plier half including a second handle, and a second jaw extending from the second handle and including second jaw teeth, wherein the first and second jaws cooperatively define a gap therebetween;
a pin pivotably coupling the first and second plier halves together at a slot, the pin adapted to be selectively movable within the slot to adjust the gap;
an adjustment mechanism disposed adjacent to the slot and including adjustment teeth;
a first receiving surface defined within the first handle and having a first receiving surface length, the first receiving surface is substantially straight and extends substantially from the first jaw teeth at a first angle relative to a plane extending along the first jaw teeth; and
a second receiving surface defined within the second handle and having a second receiving surface length that is greater than the first receiving surface length, wherein the second receiving surface is substantially straight, extends substantially from the second jaw teeth at a second angle of about 60 degrees relative to a plane extending along the second jaw teeth, and at least a portion of the second receiving surface intersects at least one of the adjustment teeth.

2. The pliers of claim 1 , wherein the first and second angles are equal.

3. The pliers of claim 1 , wherein the first and second angles are each about 60 degrees.

4. The pliers of claim 1 , wherein the adjustment teeth include first adjustment teeth disposed on the first handle, and second adjustment teeth disposed on the second handle, and the second adjustment teeth are meshingly engageable with the first adjustment teeth for releasably coupling the first and second handles together.

5. The pliers of claim 4 , wherein the first adjustment teeth respectively include first leading faces and first trailing faces, and the second adjustment teeth respectively include second leading faces and second trailing faces, and the first leading face and the second trailing face respectively extend at an angle that is about 8.5 degrees to an angle normal to the first and second handles.

6. The pliers of claim 4 , wherein the first adjustment teeth respectively include first leading faces and first trailing faces, and the second adjustment teeth respectively include second leading faces and second trailing faces, and wherein the second leading faces and the first trailing faces respectively extend at an angle that is about 25 degrees to an angle normal to the first and second handles.

7. The pliers of claim 1 , wherein the first jaw teeth intersect the first receiving surface at a first corner, and the second jaw teeth intersect the second receiving surface at a second corner, wherein the first and second comers are adapted to contact the work piece during use.

8. Pliers adapted to engage a work piece, comprising:
first and second handles respectively extending to first and second jaws cooperatively defining a gap therebetween, the first and second jaws respectively having first and second jaw teeth, the second handle including a slot;
a pin extending through the slot and dimensioned to be selectively movable within the slot to adjust the gap;
first adjustment teeth disposed on the first handle and including first leading faces and first trailing faces;
second adjustment teeth disposed on the second handle and including second leading faces and second trailing faces, wherein the second adjustment teeth are meshingly engageable with the first adjustment teeth, the first and second adjustment teeth form an adjustment mechanism, and the first leading faces and the second trailing faces respectively extend at an angle that is about 8.5 degrees to an angle normal to the first and second handles;
a first receiving surface defined within the first handle and having a first receiving surface length, the first receiving surface is substantially straight and extends substantially from the first jaw teeth at a first angle relative to a plane extending along the first jaw teeth; and
a second receiving surface defined within the second handle and having a second receiving surface length that is greater than the first receiving surface length, wherein the second receiving surface is substantially straight, extends substantially from the second jaw teeth at a second angle of about 60 degrees relative to a plane extending along the second jaw teeth, and at least a portion of the second receiving surface intersects at least one of the second adjustment teeth.

9. The pliers of claim 8 , wherein the first and second angles are equal.

10. The pliers of claim 8 , wherein the first and second angles are each about 60 degrees.

11. The pliers of claim 8 , wherein the second leading faces and the first trailing faces respectively extend at an angle that is about 25 degrees to an angle normal to the first and second handles.

12. The pliers of claim 8 , wherein the first jaw teeth intersect the first receiving surface at a first corner, and the second jaw teeth intersect the second receiving surface at a second corner, the first and second corners adapted to contact a work piece during use.

13. Pliers having a first handle pivotably coupled to a second handle at a slot of the second handle, the first and second handles respectively extending to first and second jaws cooperatively defining a gap therebetween, the first and second jaws respectively having first and second jaw teeth, the pliers comprising:
first adjustment teeth formed into and extending from a first side surface of the first handle towards the second handle;
second adjustment teeth formed into and extending from a second side surface of the second handle towards the first handle and meshingly engageable with the first adjustment teeth for releasable coupling of the first and second handles, wherein the first and second side surfaces face each other;
wherein the first adjustment teeth respectively include first leading and trailing faces that respectively extend at first leading and first trailing non-normal angles with respect to a first handle direction in which the first handle extends, and the second adjustment teeth respectively include second leading and trailing faces that respectively extend at second leading and second trailing non-normal angles with respect to a second handle direction in which the second handle extends, and wherein the first leading and second trailing non-normal angles are about 8.5 degrees,
a first receiving surface defined within the first handle and extending substantially from the first jaw teeth at a first angle; and
a second receiving surface defined within the second handle and extending substantially from the second jaw teeth at a second angle of about 60 degrees, and wherein at least a portion of the second receiving surface intersects at least one of the second adjustment teeth.

14. The pliers of claim 13 , wherein the first trailing and second leading non-normal angles are equal.

15. The pliers of claim 13 , wherein the first trailing and second leading non-normal angles are about 25 degrees.
