Abstract
An air duct fitting or pipe coupling used for connecting air conditioning or heating ducts. The fitting may be used as an integral unit to connect the ducts at a predetermined angular relationship from one another. The fitting may be severed into two sections, each section of which may be used to connect ducts at a different angular relationship from the integral unit. The fitting may be characterized as an elbow fitting. In the preferred embodiment, the fitting is a thin wall molded unit made of a non-metallic material. The first and second sections may be severed along a plane defined by a V-shaped groove molded in the fitting.
Claims22
A fitting comprising a plurality of integrally formed sections, wherein each section has means for connecting to a pair of ducts and wherein:
- the fitting may be used as an integral unit having end portions adapted for connecting a pair of ducts at a predetermined angular relationship to one another;
- and
- said sections may be severed from one another such that each of said severed sections has end portions adapted for individually connecting a pair of ducts at a different angular relationship to one another.
A fitting comprising:
- a first section having means for connecting to a pair of ducts;
- and
- a second section integrally formed with said first section, said second section having means for connecting to a pair of ducts;
- wherein:
- the fitting may be used as an integral unit having end portions adapted for connecting a pair of ducts at a predetermined angular relationship to one another;
- and
- said first and second sections may be severed from one another such that each of said first and second sections has end portions adapted for individually connecting a pair of ducts at a different angular relationship to one another.
A hollow elbow fitting adapted for connecting a pair of lengths of duct at a predetermined angle, said fitting comprising:
- a first section having means for connecting to a pair of ducts;
- and
- a second section integrally formed with said first section and severable therefrom, said second section having means for connecting to a pair of ducts;
- wherein, when said first and second sections are severed from one another, both of said first and second sections have end portions which may be individually used for connecting the pair of ducts at an angle different from said predetermined angle.
