Abstract

An alignment device to assist a user in the functional application of a hand tool. The hand tool can take a variety of forms but is preferably a dent removal tool. The alignment device is preferably retrofitable onto existing hand tools by use of a base bracket that mounts onto the handle or shank of the tool. A sight device is mounted on the device and includes a multiple degree of freedom joint. This joint allows the user to easily and quickly align the sight device to locate the work piece. The work piece can then be placed in a desired position even positioned such that it is obscured from the sight of the user. Positioning the work piece of a dent removal tool behind the opaque surface of dented sheet metal structure is a typical application. The alignment device allows the user to quickly and accurately position the work piece, behind the surface, thereby increasing the efficiency of the user.

Claims

1. An automobile dent removal tool alignment device for locating a visually obstructed workpiece comprising:

a base bracket enabling releasably secure mounting to a hand tool;

a substantially longitudinal frame comprising a base frame, an extension frame being moveably secured one to another and a joint enabling at least three degrees of freedom, said substantially longitudinal frame mounted to said base bracket; and

a sight device attached to said substantially longitudinal frame on a distal end opposite to said base bracket.

2. The alignment device as described in claim 1, wherein said sight device is comprised of a visual scope.

3. The alignment device as described in claim 1, wherein said sight device is comprised of a light source.

4. The alignment device as described in claim 3, wherein said light source is comprised of a type that emits a coherent light.

5. The alignment device as described in claim 3, wherein said light source is comprised of a laser light.

6. The alignment device as described in claim 1, wherein said joint providing at least three degrees of freedom is comprised of a spherical joint.

7. The alignment device as described in claim 6, wherein said spherical joint includes a friction lock, the joint being comprised of a spherical portion received by a concave portion and a spring enabling frictional contact between said spherical portion and said concave portion.

8. The alignment device as described in claim 1, wherein said hand tool is a dent removal tool.

9. A retrofitable automobile dent removal tool alignment device for locating a visually obstructed workpiece comprising:

a base bracket enabling releasably secure mounting to a hand tool;

a substantially longitudinal frame, including a linearly movable joint and a pivoting joint, which includes a friction lock, said frame mounted to said base bracket;

a mounting arm adapted to receive said pivoting joint; and

a sight device received by said mounting arm.

10. The retrofitable alignment device as described in claim 9, wherein said sight device is comprised of a visual scope.

11. The retrofitable alignment device as described in claim 9, wherein said sight device is comprised of a light source.

12. The retrofitable alignment device as described in claim 11, wherein said light source is comprised of a type that emits a coherent light.

13. The retrofitable alignment device as described in claim 11, wherein said light source is comprised of a laser light.

14. The retrofitable alignment device as described in claim 9, wherein said hand tool is a dent removal tool.

15. An automobile dent removal tool alignment device for locating a visually obstructed workpiece comprising:

a base bracket that enables releasable mounting to a hand tool and supports a substantially longitudinal frame, the frame comprising a base frame, an extension frame being moveably secured one to another and a joint enabling at least three degrees of freedom; and

a sight means attached to said substantially longitudinal frame on a distal end opposite to said base bracket.

16. The alignment device as described in claim 15, wherein said sight means is comprised of a visual scope.

17. The alignment device as described in claim 15, wherein said sight means is comprised of a light source.

18. The alignment device as described in claim 17, wherein said light source is comprised of a type that emits a coherent light.

19. The alignment device as described in claim 17, wherein said light source is comprised of a laser light.

20. The alignment device as described in claim 15, wherein said joint providing at least three degrees of freedom is comprised of a spherical joint.

21. The alignment device as described in claim 20, wherein said spherical joint includes a friction lock, the joint being comprised of a spherical portion received by a concave portion and a spring enabling frictional contact between said spherical portion and said concave portion.

22. The alignment device as described in claim 15, wherein said hand tool is a dent removal tool.

23. A method for locating a work piece that is visually obstructed by an opaque surface, comprising:

providing a hand tool having a work piece located thereon;

providing an alignment device that includes;

a base bracket that mounts to said hand tool and supports a substantially longitudinal frame comprising a base frame, an extension frame being moveably secured one to another and a joint enabling at least three degrees of freedom; and

a sight device attached to said substantially longitudinal frame on a distal end opposite to said base bracket;

adjusting said alignment device such that said sight device locates said work piece; and

positioning said work piece on one side of an opaque surface with said sight device on a second side thereof, whereby said sight device identifies the position of said work piece to a user.
