Abstract

A tool includes a first output from a gear system, the first output along a first axis and a second output from the gear system, the second output along a second axis. A first torque limiter is attached to the first output along the first axis and a second torque limiter is attached to the second output along the second axis. A first tool bit is attached to the first torque limiter along the first axis and a second tool bit attached to the second torque limiter along the second axis.

First claim

What is claimed is:

1 . A tool for installing and removing a module assembly, wherein the module assembly has a handle, the tool comprising:
a gear system; an input to the gear system; a first output from the gear system, the first output along a first axis; a second output from the gear system, the second output along a second axis; a first torque limiter attached to the first output along the first axis; a second torque limiter attached to the second output along the second axis; a first tool bit attached to the first torque limiter along the first axis; a second tool bit attached to the second torque limiter along the second axis; and an index configured to engage the handle of the module assembly to align the first output and the second output relative to the module assembly.

2 . The tool as recited in claim 1 , wherein the first axis and the second axis are parallel.

3 . The tool as recited in claim 1 , further comprising a housing that contains the gear system.

4 . The tool as recited in claim 1 , further comprising a tool handle that extends from the housing perpendicular to the index.

5 . The tool as recited in claim 1 , wherein the first and second torque limiter comprise a square drive interface for attachment to the output.

6 . The tool as recited in claim 1 , wherein the first and second torque limiter comprise a square drive interface for attachment of the tool bit.

7 . The tool as recited in claim 1 , wherein the first and second tool bit is a hex bit.

8 . The tool as recited in claim 1 , wherein the first and second tool bit is a screw-driver bit.

9 . The tool as recited in claim 1 , wherein the gear system comprises a staggered 5-gear pattern.

10 . The tool as recited in claim 9 , wherein each gear of the gear system is identical.

11 . The tool as recited in claim 1 , wherein the gear system comprises a 4-gear pattern that provides a scaled system between the first and second outputs.

12 . A tool for installing and removing a module assembly, comprising:
a housing comprising an index that is received onto a handle of the module assembly; a gear system contained within the housing; an input to the gear system; a first output from the gear system, the first output along a first axis; a second output from the gear system, the second output along a second axis, the second axis parallel to the first axis; a first torque limiter attached to the first output along the first axis; a second torque limiter attached to the second output along the second axis; a first tool bit attached to the first torque limiter along the first axis; and a second tool bit attached to the second torque limiter along the second axis, wherein the index is configured to position the first output and the second output relative to the module assembly.

13 . The tool as recited in claim 12 , wherein the first and second torque limiter comprise a male square drive interface for attachment to the output.

14 . The tool as recited in claim 13 , wherein the first and second torque limiter comprise a female square drive interface for attachment of the tool bit.

15 . The tool as recited in claim 12 , further comprising a tool handle that extends from the housing perpendicular to the interface.

16 . A method for installing a module assembly, comprising:
locating an index of the tool as recited in claim 1 onto the handle of the module assembly such that a respective first and second tool bit from a first and a second output of the tool are aligned and preloaded onto a first and second blind fastener of the module assembly; and driving an input to a gear system of the tool until each of a first and a second torque limiter mounted between the respective first and second output and the first and second tool bit independently reach the desired preset torque.

17 . The method as recited in claim 16 , wherein the first tool bit is located along a first axis and the second tool bit is located along a second axis.

18 . The method as recited in claim 17 , wherein the first axis is parallel to the second axis.

19 . The method as recited in claim 16 , wherein driving the input to the gear system of the tool comprises driving the input until there is a clicking from each of a first and a second torque limiter.
