Abstract

A work piece positioning tool is disclosed. The tool includes a first leg and a second leg that have work piece abutting surfaces Cooperative pivoting elements adjacent an end portion of each of the first and second legs are used for connecting the legs together in a plurality of relative angular orientations. The tool can be used in combination with first and second workpieces and first and second clamps to hold the first and second work pieces together at a desired angle.

Claims

1. A work piece positioning tool comprising:

a first leg having work piece abutting surfaces;

a second leg having work piece abutting surfaces; and

cooperative pivoting elements adjacent an end portion of each of the first and second legs for connecting the legs together in a plurality of relative angular orientations.

2. The tool of claim 1 and further comprising a fastener adapted to selectively secure the end portion of the first leg to the end portion of the second leg.

3. The tool of claim 2 wherein the fastener includes a nut adapted to engage a threaded shaft.

4. The tool of claim 3 and further comprising a spring adapted to urge the first leg away from the second leg.

5. The tool of claim 1 wherein the first leg and second leg both include a plurality of stiffening ribs positioned between their respective abutting surfaces.

6. The tool of claim 1 wherein at least one of the first leg and the second leg includes an angular travel stop angled with respect to at least one of its work piece abutting surfaces.

7. The tool of claim 1 wherein the cooperative pivoting elements include teeth positioned on both the first leg and the second leg in a radial pattern disposed about a pivoting axis.

8. The tool of claim 7 wherein the cooperative pivoting elements include a cylindrical portion projecting from the first leg and adapted to be received by a cylindrical bore in the second leg.

9. A combination, comprising:

a work piece positioning tool, comprising;

a first leg having a first flange and a second flange;

a second leg having a first flange and a second flange;

cooperative pivoting elements adjacent an end portion of each of the first and second legs for connecting the legs together in a plurality of angular orientations;

a first work piece positioned against the first flange of the first leg;

a second work piece positioned against the first flange of the second leg;

a first clamp including jaws applying pressure to the second flange of the first leg and the first work piece; and

a second clamp including jaws applying pressure to the second flange of the second leg and the second work piece.

10. The combination of claim 9 wherein the work piece positioning tool includes a fastener adapted to secure the end portion of the first leg to the end portion of the second leg in an angular orientation such that an angular orientation between the first work piece and the second work piece is substantially the same as the angular orientation between the first leg and the second leg.

11. The combination of claim 9 wherein the first leg and the second leg both include a plurality of stiffening ribs positioned between their respective first and second flanges.

12. The combination of claim 9 wherein the first leg includes a triangular wall portion connecting its first and second flange and the second leg includes a triangular wall portion connecting its first and second flange.

13. The combination of claim 9 wherein the cooperative pivoting elements include teeth positioned on both the first leg and the second leg in a radial pattern disposed about a pivoting axis of the work piece positioning tool.

14. The combination of claim 13 wherein the cooperative pivoting elements include a cylindrical portion projecting from the first leg and adapted to be received by a cylindrical bore in the second leg.

15. A method of holding a first work piece and a second work piece at an angular orientation, comprising:

adjusting an angular orientation between a first leg and a second leg of a work piece positioning tool to be substantially the same as the angular orientation between the first work piece and the second work piece, the first leg and the second leg being connected together about a pivot axis;

positioning the first leg against the first work piece;

positioning the second leg against the second workpiece;

clamping the first leg to the first work piece; and

clamping the second leg to the second work piece.

16. The method of claim 15 and further comprising:

operating a fastener to secure the first leg and the second leg together at the angular orientation.

17. The method of claim 15 wherein the first leg includes a first flange and a second flange and wherein the second leg includes a first flange and a second flange.

18. The method of claim 17 wherein the first leg includes a plurality of stiffening ribs positioned between its first flange and second flange leg includes a plurality of stiffening ribs positioned between its first flange and second flange.

19. The method of claim 15 and further comprising:

providing cooperative pivoting elements on the first leg and second leg to orient the first leg with the second leg at selected angular orientations.

20. The method of claim 19 wherein the cooperative pivoting elements include teeth positioned on the first leg and the second leg.
