Abstract

A hand-held conduit bending tool includes an elongated handle and a bender head disposed on the handle. The bender head comprising a body portion having at least one curved channel therein. In an embodiment, the channel is elliptical in cross-section. A handle mount is at a rear end of the body portion and rearward of the hook portion and a foot pedal is formed. In some embodiments, two channels are provided to accommodate two differently sized conduits. Markings are provided to enable use of the tool in a head-down position and in a head-up position.

First claim

What is claimed is:

1. A hand-held conduit bending tool for receiving first and second conduits, the first and second conduits having different diameters, the hand-held conduit bending tool comprising:
a bender head comprising
a body portion having a front end, an opposite rear end, a lower surface extending from the front end to the rear end, an opposite upper surface extending from the front end to the rear end, opposite first and second side surfaces extending from the front end to the rear end, a first body channel extending upward from the lower surface and extending from the front end to the rear end, the first body channel defining a longitudinal axis, a second body channel extending upward from the lower surface and extending from the front end to the rear end, the second body channel defining a longitudinal axis, the longitudinal axes being parallel to each other, the first body channel is configured to receive the first conduit and the second body channel is configured to receive the second conduit,
a central spine extending longitudinally from the body portion, the central spine having opposite first and second sides,
a first hook extending from the first side of the central spine, the first hook having a front end, an opposite rear end, an upper surface extending from the front end to the rear end of the first hook, an opposite bottom surface extending from the front end to the rear end of the first hook, and a first hook channel extending downward from the upper surface of the first hook and extending from the front end to the rear end of the first hook, the first hook channel configured to receive the first conduit,
a second hook extending from the second side of the central spine, the second hook having a front end, an opposite rear end, an upper surface extending from the front end to the rear end of the second hook, an opposite bottom surface extending from the front end to the rear end of the second hook, and a second hook channel extending downward from the upper surface of the second hook and extending from the front end to the rear end of the second hook, the second hook channel configured to receive the second conduit,
the bender head having a length defined in a plane between the rear end of the body portion and the front ends of the first and second hook hooks, and
a handle mount provided by the body portion proximate to the front end thereof and rearward of the central spine, the handle mount having a central axis which longitudinally aligns with the central spine and which is located along the length of the bender head at a distance of 60% to 65% of the length away from the rear end of the body portion, wherein the upper surface rearward of the handle mount forms an enlarged foot pedal which is configured to receive a foot of a user; and

an elongated handle having a free end and a connected end, wherein a central axis of the elongated handle is defined between the ends thereof and aligns with the central axis of the handle mount, the connected end of the elongated handle being in the handle mount.

2. The hand-held conduit bending tool of claim 1 , wherein the handle mount is an open ended receptacle into which the elongated handle can be inserted.

3. The hand-held conduit bending tool of claim 1 , wherein the lower surface of the body portion is radiused, the bottom surface of the first hook has a front portion extending from the front end thereof and a planar rear portion extending from the front portion to the rear end thereof, the planar rear portion being angled relative to the front portion and extending tangentially from the radiused body portion, and the bottom surface of the second hook has a front portion extending from the front end thereof and a planar rear portion extending from the front portion to the rear end thereof, the planar rear portion of the second hook being angled relative to the front portion of the second hook and extending tangentially from the radiused body portion, and wherein a part of the lower surface of the body portion and the planar rear portions of the first and second hooks are in contact with a surface when the bending tool is in a stand alone head-down and handle-up resting position.

4. The hand-held conduit bending tool of claim 1 , further comprising first markings provided on the lower surface of the body proximate to the first body channel, second markings provided on the first side surface of the body proximate to the first body channel, third markings provided on the second side surface of the body proximate to the second body channel, and fourth markings provided on the lower surface of the body proximate to the second body channel, wherein the first and second markings indicate bend angles for the first body channel, and the third and fourth markings indicate bend angles for the second body channel.

5. The hand-held conduit bending tool of claim 1 , wherein the central axis of the elongated handle is vertical when a 30 degree bend angle has been achieved.

6. The hand-held conduit bending tool of claim 3 , wherein the central axis of the elongated handle is angled relative to vertical and the elongated handle is tilted towards the front ends of the first and second hooks and away from the enlarged foot pedal when a part of the lower surface of the body portion and the planar rear portions of the first and second hooks are in contact with the surface when the bending tool is in the stand alone head-down and handle-up resting position.

7. The hand-held conduit bending tool of claim 3 , wherein
the first body channel includes opposite first and second side walls which are separated by a base wall, the first side wall terminating in a first lower wall surface, the second side wall terminating in a second lower wall surface, and the first body channel is elliptical in cross-section along all cross-sections thereof taken transverse to the longitudinal axis, and a first distance is defined from a midpoint of the base wall to the first lower wall surface, and a second distance is defined from the midpoint of the base wall to the second lower wall surface, each of the first and second distances are less than the diameter of the first conduit such that the first conduit extends partially out of the first body channel when positioned therein, and
the second body channel includes opposite first and second side walls which are separated by a base wall, the first side wall of the second body channel terminating in a first lower wall surface, the second side wall of the second body channel terminating in a second lower wall surface, and the second body channel is elliptical in cross-section along all cross-sections thereof taken transverse to the longitudinal axis of the second body channel, and a first distance is defined from a midpoint of the base wall to the first lower wall surface of the second body channel, and a second distance is defined from the midpoint of the base wall to the second lower wall surface of the second body channel, each of the first and second distances of the second body channel are less than the diameter of the second conduit such that the second conduit extends partially out of the second body channel when positioned therein.

8. The hand-held conduit bending tool of claim 1 , wherein
wherein a part of the lower surface of the body portion and parts of the first and second hooks are in contact with a surface when the bending tool is in a stand alone head-down and handle-up resting position, and
wherein the central axis of the elongated handle is angled relative to vertical and the elongated handle is tilted towards the front ends of the first and second hooks and away from the enlarged foot pedal when the bending tool is in the stand alone head-down and handle-up resting position.
