Abstract

Disclosed herein are embodiments of tools and tool kits for use with a movable work piece having at least one fastener, the tool preventing movement of the work piece and fastener when a force is exerted on the fastener. One embodiment of such a tool comprises an elongate handle, a first arm and a second arm. The first arm has a distal end with an aperture configured to engage the fastener to prevent the fastener from rotating when a rotational force is exerted on the fastener. The first arm is movably connected to the elongate handle. The second arm extends from the elongate handle. The second arm is spaced apart from the first arm and comprises a side surface configured to contact a portion of the movable work piece to prevent the work piece from movement. The first arm is movably connected to the handle proximate the second arm.

Claims (23)

1. A tool for use with a movable work piece having at least one fastener, the tool comprising:

an elongate handle;

a first arm having a distal end with an aperture configured to engage the fastener to prevent the fastener from rotating when a rotational force is exerted on the fastener, the first arm movably connected to the elongate handle; and

a second arm extending from the elongate handle, the second arm spaced apart from the first arm and comprising a side surface configured to contact a portion of the movable work piece to prevent the work piece from movement, wherein:

the first arm is movably connected to the handle proximate the second arm;

the second arm further comprises a shoe portion movably connected to and at least partially covering the side surface of the second arm, the shoe portion having a surface configured to grip the work piece; and

the shoe portion comprises a main portion movably connected to the second arm on a side opposite the first arm, and a side surface extending in an L-shape from an edge of the main portion, the side surface conforming to a shape of a surface of the work piece.

2. The tool of claim 1 , wherein the fastener has a first axis about which it rotates and the movable work piece has a second axis about which it rotates, the first arm configured to prevent rotation of the fastener about the first axis when a rotational force is being asserted on an opposite end of the fastener, while the second arm prevents rotation of the work piece about the second axis with exertion of force on the elongate handle.

3. The tool of claim 1 , wherein the second arm is an end portion of the elongate handle.

4. The tool of claim 1 , wherein the shoe portion is at least partially coated with a flexible material.

5. The tool of claim 1 , wherein the shoe portion is made of a rubber material.

6. The tool of claim 1 , further comprising means for biasing the first arm toward the second arm.

7. The tool of claim 1 , wherein the elongate handle has a contoured gripping end opposite the second arm.

8. The tool of claim 1 , wherein the handle has a padded gripping end opposite the second arm.

9. The tool of claim 1 , wherein the second arm extends from the elongate handle at an angle of less than ninety degrees.

10. The tool of claim 1 , further comprising one or more additional first arms each configured to be interchangeable with the first arm, each of the additional first arms having a distal end configured to engage a different sized or shaped fastener.

11. The tool of claim 1 , further comprising one or more additional shoe portions each configured to be interchangeable with the shoe portion, each of the additional shoe portions having a surface contoured to conform to different sized or shaped work pieces.

12. A tool for use with a movable work piece having at least one fastener, wherein the tool is used to prevent movement during loosening, tightening, or testing the fastener, the tool comprising:

an elongated main portion having a handle end configured to be gripped by a user and a work piece end configured to contact a portion of the work piece; and

a first arm having a distal end with an aperture configured to engage the fastener, the first arm movably connected to the elongated main portion at a location closer to the work piece end, wherein:

the fastener has a first axis about which it rotates and the movable work piece has a second axis about which it rotates parallel to the first axis, the first arm configured to prevent rotation of the fastener about the first axis while the work piece end of the elongated main portion prevents rotation of the work piece about the second axis when a force is exerted on the handle end;

the elongated main portion comprises a shoe portion movably connected to and at least partially covering the work piece end, the shoe portion having a surface configured to contact the work piece, wherein the shoe portion comprises a main portion movably connected to the work piece end on a side of the elongated main portion opposite the first arm, and a side surface extending in an L-shape from an edge of the main body, the side surface conforming to a contour of a surface of the work piece.

13. The tool of claim 12 , wherein the work piece end of the elongated main portion extends from the elongated main portion at an angle of less than ninety degrees.
