Abstract
A tool, such as a conduit bender, that includes a gear assembly for providing a mechanical advantage when bending a workpiece conduit. The gear assembly comprises a pinion gear rotatably coupled to a handle, the handle including a pin that can be selectively engaged with the pinion gear. The conduit bender also includes a shoe with teeth that protrude radially inward from a curved outer portion. When the conduit bender is in use, the teeth of the pinion gear engage with the teeth of the shoe.
Claims17
A tool for bending an elongated workpiece, the tool comprising:
- an elongated shaft;
- a shoe comprising an arc around which the elongated workpiece is bent and a top portion configured to surround on all sides and receive the elongated shaft;
- gear teeth extending radially from an interior surface of the arc;
- a link with opposing first and second ends along a longitudinal axis, the first end rotatably coupled to the elongated shaft at a first axis of rotation and the second end rotatably coupled to the shoe at a second axis of rotation;
- and
- a pinion gear rotatably coupled to the elongated shaft and the first end of the link at the first axis of rotation, the pinion gear rotatably engaging with the gear teeth to provide a mechanical force advantage when bending the elongated workpiece.
A tool for bending an elongated workpiece, the tool comprising:
- an elongated shaft;
- a shoe comprising a hook, a top portion and a curved portion, the top portion coupled to the curved portion and configured to receive and enclose the elongated shaft, the curved portion comprising gear teeth protruding radially inward from a top surface of the curved portion, the hook fixedly coupled to a first end of the curved portion;
- and
- a gear assembly rotatably coupled to the elongated shaft, the gear assembly engaging with the shoe.
