Abstract:
1. A quick-release connector fitting comprising, in combination: an ultra-violet resistant polyvinylchloride housing comprising a central longitudinal axis, first and second open ends, first and second cylindrically-shaped inner walls of differing predetermined diameters about the central longitudinal axis, and an annular tapered interior connecting the first and second cylindrically-shaped inner walls defining a housing interior extending between the first and second open ends; a housing exterior comprising a central longitudinal axis, a female end corresponding to the larger cylindrically-shaped inner wall and a threaded male end corresponding to the smaller cylindrically-shaped inner wall, a first external circular shaped rib extending outward from the housing to a predetermined diameter about the central longitudinal axis corresponding to the boundary between the annular tapered interior wall and the smaller cylindrically-shaped inner wall, a flanged end extending outward from the open female end, and a second external circular shaped rib extending outward from the housing to a predetermined diameter between the female end flange and first external circular shaped rib; an ultra-violet resistant polyvinylchloride water line fitting comprising a central longitudinal axis, first and second open ends, a cylindrically-shaped inner wall of diameter sized to the smaller housing inner wall diameter defining a fitting interior extending between the first and second open ends, with one open end inner wall further comprising screw threads for a predetermined length of the inner wall defining a fitting female open end; a water line fitting exterior comprising a central longitudinal axis, a male end sized to be insertably received into the housing female open end, further comprising an external circular shaped rib extending outward from the fitting male end exterior surface to a predetermined diameter about the central longitudinal axis and a circular recess extending inward from the male end surface between the external circular shaped rib and the open end corresponding to the male end sized to receive and secure an O-ring and an O-ring suitably sized for and disposed on the male end within the recess; an ultra-violet resistant polyvinylchloride end sleeve for the housing comprising a central longitudinal axis, first and second open ends, connected first and second cylindrically-shaped inner walls of differing predetermined diameters about the central longitudinal axis defining the sleeve interior extending between the first and second open ends, wherein the larger open end is sized to receive and enclose the housing female end up to the second external circular shaped rib and the smaller open end is sized to receive and enclose the water line fitting exterior male end leaving sufficient space for the male end to freely move therein along the sleeve longitudinal axis; a cylindrical end sleeve exterior comprising a semi-circular recess extending inwards and sized to receive and hold a clip, the recess further comprising two ends and two openings from the exterior through to the to the larger cylindrically-shaped inner wall, each opening at one end of the semi-circular recess; a plurality of locking mechanisms spatially oriented equidistant one from the other along a plane perpendicular to the housing central longitudinal axis, wherein each mechanism comprises a detent head accessible from the housing exterior and a deformable lock tab having elastic memory accessible from the housing larger interior wall at a predetermined distance from the housing female open end whereby when the water line fitting is insertably fitted into the housing female end the circular shaped rib communicates with the lock tabs and is thereby locked into the housing and the O-ring communicates with the annular tapered interior wall, and each detent head comprises a recess sized to receive a resilient detent locking spring; an arcuate resilient clip sized to be received into and reside in the sleeve exterior recess, the clip further comprising two arms sized to extend through the sleeve and securely engage the housing exterior; whereby the assembled connector fitting is rated to water pressures up to 250 pounds per square inch and the housing threaded male end and water line fitting threaded female end are adapted to fit varying diameter dimensions for pressurized watering systems.
