WATER FOUNTAIN RETURN FITTING FOR SWIMMING POOLS AND SPAS

Abstract

The high flow water return fitting of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, spa, or the like, it also redirects the water outflow above the water surface, producing a fountain of pressure regulated airborne stream of aeriated water, substantially increases the area of water in the pool that can be circulated or agitated,

Description

SUMMARY OF THE INVENTION

The present invention is a water return fitting that connects to the end of a water return line in a swimming pool, spa, or the like and through which filtered water is pumped back into the swimming pool, spa, or the like. A unique curved pressure adjustable tube operates in conjunction with a adjustable head and various nozzle to produce a fountain of aeriated water into the swimming pool, spa, or the like.

Yet another object of the present invention is to provide a detachable fitting to allow ease of mounting and providing disconnection when minimal force is applied to the return fitting preventing a safety hazard to swimmers.

Yet another object of the present invention is to provide a water return fitting that can rotate 360 degrees

Yet another object of the present invention is to provide a water return fitting with a nozzle that can rotate 360 degrees.

Yet another object of the present invention is to provide a pressure regulation method via the perforated tube and sleeve alignment.

Yet another object of the present invention is to provide a water return fitting that is length adjustable enabling the nozzle to protrude above the water surface regardless of the distance from the water return line and the water surface.

Yet another object of the present invention is to provide a water return fitting that is easy to install into the end of a water return line and is manufactured out of plastic material to reduce cost and eliminate risk of corrosion.

Yet another object of the present invention is to provide a water return fitting with multiple parts that can be easily assembled correctly without the need of special tools or equipment.

The above objects and other features of the present invention, as well as the structure and operation of various embodiments of the present invention, are described in detail below and with reference to the accompanying drawings.

A water return fitting that connects to a water return line of a swimming pool, spa, or the like, redirecting the water outflow above the water surface, producing a fountain of pressure regulated, aeriated water, substantially increases the area of water in the pool that can be circulated or agitated, and comprising of: A mounting ring with grooves and threads (“Mount Ring”), said mounting ring connector having a front end and a back end and that is in physical connection with said water return line, and that is in fluid communication with said water return line. A tube with threads and grooves (“Retaining Tube”), said tube connector having a front end and a back end and that is in physical connection with said mounting ring, and that is in fluid communication with said water return line. A tube with locking clips (“Mount Clip”), said mount clip connector having a front end and a back end and that is in physical connection with said mounting ring and retaining tube. A curved perforated tube with threads and grooves (“Lower Tube”), said lower tube connector having a front end and a back end and that is in physical connection with retaining tube and mount clip, and that is in fluid communication with said water return line. A perforated tube (“Bypass Tube”), said perforated tube having a front end and a back end, and that is in physical connection with lower tube. A retention ring with threads and grooves (“Lower Ring”), said lower ring having a front end and a back end, and that is in physical connection with lower tube and bypass tube. A tube with threads and grooves (“Upper Tube”), said upper tube having a front end and a back end and that is in physical connection with said lower tube, upper ring, and head, and that is in fluid communication with said water return line. A retention ring with threads and grooves (“Upper Ring”), said upper ring having a front end and a back end and that is in physical connection with said upper tube, and head. A curved tube with threads and grooves (“Head”), said head having a front end and a back end, and that is in physical connection with extension tube and curved tube, and that is in fluid communication with said water return line. A tube with threads and grooves (“Stream Nozzle”), said stream nozzle having a front end and a back end and that is in physical connection with said head, and that is in fluid communication with said water return line. A curved tube with threads, grooves, and a light emitting within the center of the tube (“lighted Head”), said lighted head interchangeable with the head of the water return fitting, having a front end and a back end, and that is in physical connection with extension tube and curved tube, and that is in fluid communication with said water return line.
