Abstract
A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand upon which at least one pipe threading tool is supported, a drive assembly mounted to the stand including an electric motor operable to provide torque to the pipe, and a lift-assist mechanism coupled to the stand. The stand is foldable about a pivot axis between a collapsed state and a deployed state, and the lift-assist mechanism is configured to apply a moment to the stand about the pivot axis during adjustment from the collapsed state to the deployed state.
Claims21
A portable pipe threader comprising:
- a stand upon which a pipe is supported;
- a carriage supported by the stand upon which at least one pipe threading tool is supported;
- a drive assembly mounted to the stand including an electric motor operable to provide torque to the pipe;
- and
- a lift-assist mechanism coupled to the stand,
- wherein the stand is foldable about a pivot axis between a collapsed state and a deployed state, and wherein the lift-assist mechanism is configured to apply a moment to the stand about the pivot axis during adjustment from the collapsed state to the deployed state.
A portable pipe threader comprising:
- a stand upon which a pipe is supported, the stand including a first pair of legs and a second pair of legs that are pivotably coupled to the first pair of legs about a pivot axis;
- a carriage supported by the stand upon which at least one pipe threading tool is supported;
- a drive assembly mounted to the stand including an electric motor operable to provide torque to the pipe;
- and
- a lift-assist mechanism coupled between the first pair of legs and the second pair of legs,
- wherein the stand is foldable about the pivot axis between a collapsed state and a deployed state, and wherein the lift-assist mechanism is configured to continuously bias the stand into the deployed state.
A portable pipe threader comprising:
- a stand upon which a pipe is supported, the stand including a frame that has
- a first pair of legs and a second pair of legs that are pivotably coupled to the first pair of legs about a pivot axis, and
- a handle assembly coupled to each of the second pair of legs;
- a carriage supported by the stand upon which at least one pipe threading tool is supported;
- a drive assembly mounted to the stand including an electric motor operable to provide torque to the pipe;
- and
- a lift-assist mechanism coupled to the stand,
- wherein the stand is foldable about a pivot axis between a collapsed state and a deployed state,
- wherein the lift-assist mechanism is configured to continuously bias the stand into the deployed state, and
- wherein the handle assembly of each of the second pair of legs support the stand in the deployed state.
