Barbed connection for use with irrigation tubing
First Claim
1. A barbed connection for irrigation tubing, the barbed connection comprising a hollow tubular body having a central axis and an open end, a first circumferential barb extending from the body to a first circumferential maximum radius from the central axis and at least one corner barb extending from the body and positioned on an opposite side of the first circumferential barb from the open end of the body, each of the corner barbs having a pair of corners extending to a corner maximum radius from the central axis and an intermediate structure extending between the pair of corners and having a midpoint at a midpoint maximum radius from the central axis, wherein the corner maximum radius is greater than the first circumferential maximum radius and the midpoint maximum radius is less than the first maximum radius, and wherein the corner maximum radius is the radially outermost part of the corner barb.

Abstract
A multi-barbed connection suitable for use in connecting a piece of flexible irrigation tubing is provided, where one of the barbs is a circumferential barb configured for forming a generally fluid tight connection with the tubing and another of the barbs is a corner barb having one or more corners configured for biting into the tubing for at least partially assisting in retaining the tubing on the connection. The connection can be part of a fitting for fluidly joining multiple pieces of tubing or part of an irrigation device, such as a pop-up irrigation sprinkler.

- 1. A barbed connection for irrigation tubing, the barbed connection comprising a hollow tubular body having a central axis and an open end, a first circumferential barb extending from the body to a first circumferential maximum radius from the central axis and at least one corner barb extending from the body and positioned on an opposite side of the first circumferential barb from the open end of the body, each of the corner barbs having a pair of corners extending to a corner maximum radius from the central axis and an intermediate structure extending between the pair of corners and having a midpoint at a midpoint maximum radius from the central axis, wherein the corner maximum radius is greater than the first circumferential maximum radius and the midpoint maximum radius is less than the first maximum radius, and wherein the corner maximum radius is the radially outermost part of the corner barb.
- 12. A barbed connection for irrigation tubing, the barbed connection comprising a hollow tubular body having a central axis and an open end, a first circumferential barb extending from the body to a first circumferential maximum radius from the central axis and at least one corner barb extending from the body and positioned on an opposite side of the first circumferential barb from the open end of the body, each of the corner barbs having a pair of corners extending to a corner maximum radius from the central axis and an intermediate structure extending between the pair of corners and having a midpoint at a midpoint maximum radius from the central axis, wherein the corner maximum radius is greater than the first circumferential maximum radius and the midpoint maximum radius is less than the first maximum radius, further comprising a second circumferential barb extending to a second circumferential maximum radius from the central axis and positioned on an opposite side of the at least one corner barb from the first circumferential barb, wherein the second circumferential maximum radius is greater than the first circumferential maximum radius.
