20090293188 | Hydrotherapy Apparatus & Method - A hydrotherapy apparatus used with a pool includes a hydrotherapy jet having an inlet and an outlet through which a pressurized water jet is expelled. A mounting structure immerses the hydrotherapy jet into water in the pool and is adjustable for moving the hydrotherapy jet into different positions to direct a water jet against different parts of the body of a person in the pool. A floating recliner supports a user of almost any size in a seated or reclining position while at least partially immersed in the water in the pool. A water circulation system pumps water in the pool into the inlet and out the outlet of the hydrotherapy jet to provide the pressurized water jet. | 12-03-2009 |

20110004993 | Swimming pool with eductor jets - A swimming pool designed for stationary swimming uses Venturi-based eductor jets to generate a forceful water flow augmented by entrained pool water drawn from within the pool enclosure. The eductor jets use the kinetic energy of the inlet flow to entrain the low-pressure pool water, completely mix the two, and then discharge the mixture as an augmented outlet flow. The energy from the motive inlet flow is transferred to the entrained pool water via the Venturi effect. As the motive inlet water passes through a tapered nozzle in the eductor jet, kinetic energy increases and pressure decreases. This produces a Venturi effect which draws surrounding pool water into the Venturi orifice of the eductor jet. Consequently, the volume of the outlet flow from the eductor jets is 3 to 5 times the volume of the inlet flow. A larger and more powerful stream of water is thereby discharged into the pool enclosure and provides optimal resistance for in-place swimming in an energy-efficient manner. | 01-13-2011 |
20120124732 | Portable Spa - A spa pool assembly has a pool having an enclosing wall and a base that together defines an interior. The base has a plurality of inflatable sections that are divided by a plurality of air passages that includes a first air passage that has a plurality of small bubble openings, and a second air passage that has a plurality of large bubble openings. The small bubble openings eject bubbles that are smaller in size than the bubbles ejected from the large bubble openings. The spa pool assembly can also include a bubble controller that controls the ejection of bubbles from the small bubble openings and the large bubble openings. | 05-24-2012 |
20120131741 | Combinable and Interchangeable Water Features - Combinable and interchangeable water features used on a standard universal mounting system to create the desired color, style, jet, directional flow, filter, light, return fittings, or other water feature for a pool or spa. Some water features include removably attached and rotatable male receptor and female receiver connections to create a variety of water effects. | 05-31-2012 |
20130031711 | POOL FILTER SYSTEMS INCLUDING POOL JET FITTINGS - Disclosed is a pool jet fitting configured to direct flow of water in a closed loop pool pumping filtration system. The pool jet fitting may include a housing, and a valve positioned in the housing. The housing may include a housing body that defines a bore that extends through the housing body. The housing body may include a coupler that is configured to mate with a coupler of a wall mount so as to releasably couple the housing to the wall mount. The valve may be positioned in the bore of the housing and may be configured to receive water flow from a water pump. The valve may define an adjustable opening having a dimension capable of automatically adjusting between a first dimension and a second dimension to facilitate a predetermined outflow velocity of the water received from the pump. | 02-07-2013 |
20130061383 | HIGH FLOW WATER RETURN FITTING FOR SWIMMING POOLS AND SPAS - 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, it also substantially increases the water outflow so that a greater area of water in the pool can be circulated or agitated. The present invention has a uniquely curved nozzle with a flat flange. Both the curvature of the nozzle and the flat flange promote the accumulation of water within the nozzle so as to build up pressure that then pushes the water out a small outlet hole at a greater rate than does a conventional water return fitting. The outflow from the nozzle then creates a low pressure condition within a mixing chamber. Thus, the low pressure condition draws water in from the swimming pool through various louvers into the mixing chamber where it is mixed with the outflow of water from the nozzle to increase the total amount of water flowing out of the water return fitting of the present invention. | 03-14-2013 |
20130185863 | AUTOMATICALLY ADJUSTING POOL JET FITTING - In accordance with an embodiment, a pool jet fitting can include a housing and a redirector coupled to the housing. The housing can include a housing body and a bore that extends through the housing body along a first direction. The bore is configured to receive a water flow. The redirector is disposed within the bore of the housing. The redirector can define an opening through which the water flow moves. The redirector can include an actuator that is configured to automatically move the opening from a first configuration to a second configuration upon application of heat to the water flow by a heater. The water flow through the opening has a first trajectory when the opening is in the first configuration and a second trajectory when the opening is in the second configuration. The second trajectory is different than the first trajectory relative to the first direction. | 07-25-2013 |
20140157507 | LOW GRAVITY FED WATER SYSTEM WITHOUT SUBMERSED DRAINS WITHIN THE BATHING CHAMBER FOR POOLS AND SPAS - A low gravity fed water system includes a housing having an inlet opening, a portion of the inlet opening disposed above the waterline and a portion of the inlet opening disposed below the waterline. The housing has an outlet opening disposed in the housing below the waterline in fluid communication with the plurality of jets. The housing has a vent opening disposed in the housing below the waterline. An upwardly-extending conduct is connectable at a first end to the vent opening, and has a second end disposed above the waterline in ambient air away from an inside surface of the housing and away from an inside surface of the tub. In the event of a blockage of the inlet opening, air is drawn into the housing via the conduit inhibiting a suction being drawn on the inlet opening. | 06-12-2014 |
