Abstract

A wrench includes a body having a head and a handle portion defining a longitudinal axis. The wrench includes a first jaw coupled to the head with the first jaw including first teeth and an edge. The edge defines a width of the first jaw. The wrench includes a second jaw extending through an aperture of the head with the second jaw including a threaded portion and second teeth. The wrench includes an actuator coupled to the threaded portion of the second jaw such that rotation of the actuator relative to the second jaw moves the second teeth relative to the first teeth. A length is measured from the edge of the first jaw to the second end of the handle portion parallel to the longitudinal axis. A ratio of the width of the first jaw over the length is less than 0.06.

First claim

The invention claimed is:

1. A wrench comprising:
a body including
a head having an aperture, and
a handle portion defining a longitudinal axis, the longitudinal axis centrally extending through a first end of the handle portion adjacent the head and a second end of the handle portion opposite the first end;

a first jaw coupled to the head, the first jaw including first teeth and an edge, the edge being transverse to the longitudinal axis and distal to the aperture of the head, the edge defining a width of the first jaw;
a second jaw extending through the aperture of the head, the second jaw including a threaded portion and second teeth; and
an actuator coupled to the threaded portion of the second jaw such that rotation of the actuator relative to the second jaw moves the second teeth of the second jaw relative to the first teeth of the first jaw;
wherein a length is measured from the edge of the first jaw to the second end of the handle portion parallel to the longitudinal axis;
wherein the edge of the first jaw is a first edge, and wherein the second jaw includes a second edge adjacent the second teeth, and wherein the second jaw is moveable relative to the first jaw to define a maximum distance between the first edge and the second edge, and wherein a ratio of the maximum distance over the length is less than 0.13; and
wherein a ratio of the width of the first jaw over the length is less than 0.06.

2. The wrench of claim 1 , wherein the handle portion is integrally formed with the head as a single component.

3. The wrench of claim 2 , wherein the handle portion is non-circular in shape within a plane that intersects the handle portion transverse to the longitudinal axis.

4. The wrench of claim 3 , wherein the handle portion includes an I-shaped profile within the plane that intersects the handle portion.

5. The wrench of claim 1 , wherein a ratio of the width of the first jaw over the maximum distance is less than 1.

6. The wrench of claim 5 , wherein the length is greater than 10 inches.

7. The wrench of claim 6 , wherein the length is between 15 inches and 19 inches.

8. The wrench of claim 7 , wherein the width of the first jaw is between 0.7 inches and 0.8 inches.

9. The wrench of claim 8 , wherein the maximum distance between the first and second edges is between 1 inch and 2.5 inches.
