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

[0001] 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.

[0002] 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.

[0003] Yet another object of the present invention is to provide a water return fitting that can rotate 360 degrees

[0004] Yet another object of the present invention is to provide a water return fitting with a nozzle that can rotate 360 degrees.

[0005] Yet another object of the present invention is to provide a pressure regulation method via the perforated tube and sleeve alignment.

[0006] 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.

[0007] 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.

[0008] 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.

[0009] 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.
