Abstract
An assembly for bending a conduit and a portable conduit bender. The assembly may generally include a portable bender including a base having a base surface supportable on a work surface, a housing supported by the base and defining a housing axis, the housing including a handle engageable by an operator to carry the bender, and a shoe supported by the housing for pivoting movement about the housing axis, the shoe defining a channel for supporting a conduit to be bent; and a pipe threader removably supported by the housing, the threader being operable to pivotably drive the shoe relative to the housing to bend the conduit.
Claims13
A portable bender comprising:
- a base supportable on a work surface;
- a housing supported by the base, the housing including a hollow spindle having an outer surface and defining a housing axis;
- an annular shoe extending from an inner surface supported by the outer surface of the spindle for pivoting movement about the housing axis, the shoe defining a channel for supporting conduit to be bent, the shoe being pivotable about the housing axis to bend the conduit;
- and
- a gear assembly operable to drive the shoe, the gear assembly including a ring gear connected to the shoe, a spur gear meshed with the ring gear, and an input shaft supporting the ring gear and supported by the housing for rotation about a shaft axis, the input shaft being drivable to rotate the spur gear about the shaft axis to thereby pivot the ring gear and the shoe about the housing axis;
- wherein the shaft axis extends parallel to and is offset from the housing axis.

A portable bender comprising:
- a base supportable on a work surface;
- a housing supported by the base, the housing including a hollow spindle having an outer surface and defining a housing axis;
- an annular shoe extending from an inner surface supported by the outer surface of the spindle for pivoting movement about the housing axis, the shoe defining a first channel and a second channel for supporting a first conduit and a second conduit, respectively, to be bent, the shoe being pivotable about the housing axis to bend the conduit;
- wherein the first channel supports the first conduit up to a first diameter, and the shoe defines the second channel for supporting the second conduit up to a second diameter, the second diameter being greater than the first diameter, the shoe pivoting relative to the housing to selectively bend one of the first conduit and the second conduit when supported by the shoe;
- a gear assembly operable to drive the shoe, the gear assembly including a ring gear connected to the shoe, a spur gear meshed with the ring gear, and an input shaft supporting the ring gear and supported by the housing for rotation about a shaft axis, the input shaft being drivable to rotate the spur gear about the shaft axis to thereby pivot the ring gear and the shoe about the housing axis;
- and
- a drive mechanism operable to pivotably drive the shoe relative to the housing to bend one of the conduits;
- wherein the shaft axis extends parallel to and is offset from the housing axis.
