Abstract

A tool extension adapted to couple to a drive lug of a driver and a tool that allows the tool to reach hard to reach places without room for a coupling. The tool extension voids the need for a larger diameter coupling by including a female recess in an end of the tool extension that receives the bit into the shaft itself.

First claim

What is claimed is:

1 . A tool extension for a tool and that is adapted to be coupled to a drive lug of a driver comprising:
an elongated shank having opposing first and second ends; a first recess formed in the first end and adapted to matingly engage the tool; and a second recess formed in the second end and adapted to matingly engage the drive lug.

2 . The tool extension of claim 1 , wherein the shank has a round cross-section.

3 . The tool extension of claim 1 , wherein a cross-section of the shank has a size that is the same as a size of a cross-section of the first end.

4 . The tool extension of claim 3 , wherein a cross-section of the second end is larger than the cross-section of the first end.

5 . The tool extension of claim 1 , wherein the first recess has a hexagonal cross-sectional shape.

6 . The tool extension of claim 1 , wherein the second recess has a square cross-sectional shape.

7 . A tool extension comprising:
an elongated shank having opposing first and second ends; a tool bit formed at the first end; and a recess formed in the second end and adapted to receive a drive lug of a driver.

8 . The tool extension of claim 7 , wherein the shank has a round cross-section.

9 . The tool extension of claim 8 , wherein a cross-section of the shank is the same size as a cross-section of the first end.

10 . The tool extension of claim 9 , wherein a cross-section of the second end is larger than the cross-section of the first end.

11 . The tool extension of claim 7 , wherein a cross-section of the tool bit is hexagonal.

12 . The tool extension of claim 7 , wherein the recess has a square cross-sectional shape.

13 . The tool extension of claim 7 , wherein the tool bit is a bit driver.

14 . The tool extension of claim 7 , wherein the driver is a ratchet wrench, a drill, or an impact driver.
