Abstract
A plastic pipe bending jig is provided with two offset bending members to fabricate an offset bent pipe. Each bending member is provided with first and second support surfaces, wherein the first support surfaces of each bending member are linearly aligned with each other and the second support surface of each bending member are parallel but offset from each other. The position of the bending members is adjustable so that the pipe offset can be changed as desired.
Claims13
An apparatus for bending heat deformable pipe to a predetermined offset distance comprising:
- a support member;
- a first offset bending member secured to said support member and having first and second surfaces generally configured to support first and second portions of a pipe to be bent, said first and second support surfaces intersecting at a first predetermined bending angle;
- a second offset bending member secured to said support member and having third and fourth surfaces generally configured to support third and fourth portions of said pipe to be bent, said third and fourth support surfaces intersecting at a second predetermined bending angle;
- and
- means to adjustably position at least one of said first and second offset bending members at a plurality of predetermined positions on said support member, each of said predetermined positions corresponding to a predetermined offset distance such that at each of said predetermined positions, a portion of said first support surface is linearly aligned with a portion of said third support surface and a portion of said second support surface is parallel to and at a predetermined offset distance from a portion of said fourth support surface.

An apparatus for bending heat deformable pipe comprising:
- a support member;
- a first offset bending member secured to said support member and having first and second linearly extending surfaces intersecting at a first predetermined bending angle, wherein said first and second extending surfaces support corresponding portions of a pipe to be bent on either side of said first angle;
- a second offset bending member secured to said support member and having third and fourth linearly extending surfaces intersecting at a second predetermined bending angle, wherein said third and fourth extending surfaces support corresponding portions of said pipe to be bent on either side of said second angle;
- and
- means to adjustably position at least one of said first and second offset bending members at a plurality of predetermined positions on said support member, each of said predetermined positions corresponding to a desired offset distance such that at each of said predetermined positions, a portion of said first surface is linearly aligned with a portion of said third surface and a portion of said second surface is parallel to and at a desired offset distance from a portion of said fourth surface.
