Abstract

Claims (48)

1. A tool, comprising:

(a) a filament guide having a longitudinally extending trough defined by a trough wall and having a length, and

(b) an alignment system having,

(i) a first registration surface configured and arranged to transversely align a hole in a target-piece with the trough when the target-piece abuts the first registration surface, and

(ii) a second registration surface configured and arranged to laterally align a hole in a target-piece with the trough when the target-piece abuts the second registration surface,

(c) whereby a flexible filament may be threaded into a hole in a target-piece by (i) abutting the target-piece against the first and second registration surfaces so as to longitudinally align the hole with the trough, (ii) laterally and transversely constraining a distal portion of the flexible filament within the trough by forcing the distal portion of the flexible filament against the trough wall and generating a transverse deflection of the distal portion of the flexible filament, and (iii) moving the constrained distal portion of the flexible filament along the length of the trough and into the aligned hole in the target-piece.

2. The tool of claim 1 further comprising a third registration surface configured and arranged to longitudinally position a hole in a target-piece immediately adjacent a longitudinal end of the trough.

3. The tool of claim 1 constructed from a single unitary mass.

4. The tool of claim 1 wherein the tool has no moving parts.

5. The tool of claim 1 wherein the trough is a V-shaped, U-shaped or circular segment shaped trough.

6. The tool of claim 1 wherein the entire length of the trough is linear.

7. The tool of claim 1 wherein the trough is curved.

8. A tool, comprising:

(a) a sheet guide having a longitudinally extending trough defined by a trough wall and having a length, and

(b) an alignment system having,

(i) a first registration surface configured and arranged to transversely align a hole in a target-piece with the trough when the target piece abuts the first registration surface, and

(ii) a second registration surface configured and arranged to laterally aligning a hole in a target-piece with the trough when the target piece abuts the second registration surface,

(c) whereby a flexible sheet may be inserted into a hole in a target-piece by (i) abutting the target-piece against the first and second registration surfaces so as to longitudinally align the hole with the trough, (ii) laterally and transversely constraining a distal portion of the flexible sheet within the trough by forcing the distal portion of the flexible sheet against the trough wall and generating a transverse deflection of the distal portion of the flexible sheet, and (iii) moving the constrained distal portion of the flexible sheet along the length of the trough and into the aligned hole in the target-piece.

9. The tool of claim 8 further comprising a third registration surface configured and arranged to longitudinally position a hole in a target-piece immediately adjacent a longitudinal end of the trough.

10. The tool of claim 8 constructed from a single unitary mass.

11. The tool of claim 8 wherein the tool has no moving parts.

12. The tool of claim 8 wherein the trough is a U-shaped trough with a curved or planar base, or a circular segment shaped trough.

13. A method of threading a flexible filament into a hole in a target-piece, comprising:

(a) obtaining a tool, comprising:

(i) a filament guide having a longitudinally extending trough defined by a trough wall and having a length, and

(ii) an alignment system having,

(A) a first registration surface configured and arranged to transversely align the hole in the target-piece with the trough when the target-piece abuts the first registration surface, and

(B) a second registration surface configured and arranged to laterally align the hole in the target-piece with the trough when the target-piece abuts the second registration surface,

(b) abutting the target-piece against the first and second registration surfaces so as to longitudinally align the hole with the trough,

(c) laterally and transversely constraining a distal portion of the flexible filament within the trough by forcing the distal portion of the flexible filament against the trough wall and generating a transverse deflection of the distal portion of the flexible filament, and

(d) moving the constrained distal portion of the flexible filament along the length of the trough and into the aligned hole in the target-piece.

14. The method of claim 13 wherein step (b) is performed by hand.

15. The method of claim 13 wherein step (b) is automated.

16. The method of claim 13 wherein steps (c) and (d) are performed by hand.

17. The method of claim 13 wherein steps (c) and (d) are automated.

18. A method of inserting a flexible sheet into a hole in a target-piece, comprising:

(a) obtaining a tool, comprising:

(i) a sheet guide having a longitudinally extending trough defined by a trough wall and having a length, and

(ii) an alignment system having,

(A) a first registration surface configured and arranged to transversely align the hole in the target-piece with the trough when the target-piece abuts the first registration surface, and

(B) a second registration surface configured and arranged to laterally align the hole in the target-piece with the trough when the target-piece abuts the second registration surface,

(b) abutting the target-piece against the first and second registration surfaces so as to longitudinally align the hole with the trough,

(c) laterally and transversely constraining a distal portion of the flexible sheet within the trough by forcing the distal portion of the flexible sheet against the trough wall and generating a transverse deflection of the distal portion of the flexible sheet, and

(d) moving the constrained distal portion of the flexible sheet along the length of the trough and into the aligned hole in the target-piece.

19. The method of claim 18 wherein step (b) is performed by hand.

20. The method of claim 18 wherein step (b) is automated.

21. The method of claim 18 wherein steps (c) and (d) are performed by hand.

22. The method of claim 18 wherein steps (c) and (d) are automated.
