Abstract

A tool for bending an elongated workpiece includes a shaft having a first shaft portion and a second shaft portion, and a coupling assembly coupling the first shaft portion and the second shaft portion. The coupling assembly has a locked configuration in which the coupling assembly inhibits movement of the first shaft portion relative to the second shaft portion and an unlocked configuration in which the coupling assembly permits movement of the first shaft portion relative to the second shaft portion. The tool also includes a shoe coupled to the second shaft portion. The shoe has a curved bottom portion and a hook configured to hold the workpiece against the curved bottom portion. The curved bottom portion is engageable with the workpiece to bend the workpiece.

First claim

What is claimed is:

1. A method of bending an elongated workpiece, the method comprising:
positioning the workpiece against a curved bottom portion of a shoe;
bending the workpiece with the shoe by applying force to a shaft extending from the shoe;
reorienting a first portion of the shaft relative to a second portion of the shaft, defining a reoriented position, the second portion of the shaft being coupled to the shoe;
after reorienting, moving a wedge member by releasing an actuator to secure the first portion of the shaft and second portion of the shaft in the reoriented position; and
after securing in the reoriented position, further bending the workpiece with the shoe by applying force to the shaft.

2. The method of claim 1 , wherein bending the workpiece includes moving the first portion of the shaft in a first direction, and wherein reorienting includes moving the first portion of the shaft in a second direction opposite the first direction.

3. The method of claim 1 , wherein the actuator is connected to the wedge member through an interior of the first portion of the shaft.

4. The method of claim 1 , wherein the actuator is located on the first portion of the shaft.

5. The method of claim 1 , wherein the first portion of the shaft defines a longitudinal axis and wherein the wedge member is movable along the longitudinal axis.

6. The method of claim 1 , wherein the wedge member is part of a coupling assembly, and wherein the reorienting includes moving the coupling assembly between a locked configuration in which the coupling assembly inhibits movement of the first portion of the shaft relative to the second portion of the shaft, and an unlocked configuration in which the coupling assembly permits movement of the first portion of the shaft relative to the second portion of the shaft.

7. The method of claim 6 , wherein the first portion of the shaft defines a first longitudinal axis, the second portion of the shaft defines a second longitudinal axis, wherein the coupling assembly defines a pivot axis transverse to the first longitudinal axis and the second longitudinal axis, and wherein the first portion of the shaft is pivotable relative to the second portion of the shaft about the pivot axis when the coupling assembly is in the unlocked configuration.

8. The method of claim 6 , wherein the coupling assembly further includes a first toothed member coupled to the first portion of the shaft and a second toothed member coupled to the second portion of the shaft, and wherein, when the coupling assembly is in the locked configuration, the first toothed member is engaged with the second toothed member.

9. The method of claim 8 , wherein, when the coupling assembly is in the unlocked configuration, the first toothed member is disengaged from the second toothed member.

10. A method of bending an elongated workpiece, the method comprising:
positioning the elongated workpiece against a bottom portion of a shoe;
bending the elongated workpiece with the shoe by applying force to a shaft extending from the shoe;
reorienting a first portion of the shaft relative to a second portion of the shaft, defining a reoriented position, the second portion of the shaft being coupled to the shoe; and
moving a wedge member by releasing an actuator to secure the first portion of the shaft and second portion of the shaft in the reoriented position.

11. The method of claim 10 , further comprising:
further bending the elongated workpiece with the shoe by applying force to the shaft following reorienting the first portion of the shaft.

12. The method of claim 10 , wherein the actuator is coupled to an end of the first portion of the shaft and connected to the wedge member through an interior of the first portion of the shaft.

13. The method of claim 10 , wherein bending the elongated workpiece includes pivoting the first portion of the shaft in a first direction.

14. The method of claim 13 , wherein reorienting includes pivoting the first portion of the shaft in a second direction opposite the first direction.

15. The method of claim 10 , wherein the wedge member is part of a coupling assembly, and wherein reorienting includes moving a coupling assembly that pivotably couples the first portion of the shaft and the second portion of the shaft.

16. The method of claim 15 , further comprising moving the coupling assembly between a locked configuration in which the coupling assembly fixes the first portion of the shaft relative to the second portion of the shaft, and an unlocked configuration in which the coupling assembly permits the first portion of the shaft to pivot relative to the second portion of the shaft.

17. A method of bending an elongated workpiece, the method comprising:
positioning the elongated workpiece against a bottom portion of a shoe;
bending the elongated workpiece with the shoe by applying force to a shaft extending from the shoe;
depressing an actuator to move a wedge member of a coupling assembly that couples a first portion of the shaft and a second portion of the shaft into an unlocked configuration, the wedge member moving toward the second portion of the shaft;
pivoting the first portion of the shaft relative to the second portion of the shaft, the second portion of the shaft being coupled to the shoe;
releasing the actuator to move the wedge member and secure the coupling assembly in a locked configuration with the first portion of the shaft and second portion of the shaft in a pivoted position; and
further bending the elongated workpiece with the shoe by applying force to the shaft.

18. The method of claim 17 , wherein the coupling assembly includes a first toothed member coupled to the first portion of the shaft and a second toothed member coupled to the second portion of the shaft.

19. The method of claim 18 , wherein the first toothed member is engageable with the second toothed member to selectively inhibit the first portion of the shaft from pivoting relative to the second portion of the shaft.

20. The method of claim 17 , wherein releasing the actuator further comprises moving the wedge member away from the second portion of the shaft.
