20090000021 | Rotating Pop Up Pool Cleaning Head - A pop up nozzle assembly useful for cleaning swimming pool surfaces is disclosed. The present invention includes a continuously rotating spray nozzle, a water driven impeller, gearing to move the pop up head, interchangeable heads, and means for returning back within the floor or wall. The present invention includes important features for efficient cleaning, easy removal for repair, and the prevention of vandalism. | 01-01-2009 |
20100125942 | Pool Skimmer with Integral Disinfectant Dispenser - A swimming pool skimmer formed to include an integral disinfectant dispenser. The disinfectant dispenser is adapted to enable infinite adjustment to the level of disinfectant dispensed into the normal flow of the pool water. The skimmer includes a valve that is used to adjust the flow of water distributed to the disinfectant dispenser. The flow rate of water entering the dispensing chamber is controlled by the valve, which controls the water level within the dispensing chamber. The amount of water exiting the dispensing chamber is controlled by a vertically extending elongated flow slit. The higher the water level in the dispensing chamber causes more exposure to the chlorine tablets, increasing the chlorine level in the dispensing water. Chlorinated water exits the flow slit and enters the skimmer main chamber. | 05-27-2010 |
20120227175 | Swimming pool circulation and cleaning system - A swimming pool circulation and cleaning system includes a first zone with a plurality of stationary wall inlet nozzles and a second zone with a plurality of pop-up nozzles. The stationary wall inlet nozzles are strategically located in the walls of the swimming pool. Each stationary wall inlet nozzle comprises several tangential openings for directing the forced water flows downwardly towards the pool floor. The pop-up nozzles are strategically located in the pool floor to work in conjunction with the stationary wall inlet nozzles to continue the water flow from the stationary wall inlet nozzles in a direction towards the main pool drain. The pop-up nozzles may be non-rotating or rotating only about 90 degrees. A water recirculation system can be operated to re-circulate and deliver the swimming pool water either sequentially or simultaneously to the stationary wall inlet nozzles and the floor pop-up nozzles. | 09-13-2012 |
20120291193 | SYSTEM FOR FILTERING WATER FROM SWIMMING POOLS - A system for cleaning water of a swimming pool is disclosed. The system includes at least one first housing, at least one second housing, at least one third housing and pipes. The first housing includes at least one skimmer element and a corresponding filtration element. The skimmer element receives water. The corresponding filtration element filters water drawn via the skimmer element. The second housing includes a pump element spaced apart from the first housing and draws water from the swimming pool and pump water into the first housing through the skimmer element and the filtration element, for filtering and purification purposes and finally ejecting filtered water. The third housing is spaced apart from the first and second housing and includes an output element to receive and eject filtered water. The system of the present disclosure is non invasive in nature and provides flexibility of installation. | 11-22-2012 |
20130007954 | Method and apparatus for cleaning pools with reduced energy consumption - Methods and apparatus are disclosed for substantially improving the energy efficiency of swimming pools having in-floor cleaning systems. Comprehensive data is provided demonstrating the improvement in cleaning capacity realized in a typical prior art pool before and after conversion to the present invention. Methods are disclosed for the reallocation of all or a substantial part of the increase in cleaning capacity toward a proportionate reduction in energy consumption by reducing the run time or operating speed of the pool pump motor while maintaining the same or a higher level of cleaning capacity achieved by the prior art. | 01-10-2013 |
20140237713 | METHODS AND APPARATUSES FOR A VARIABLE DEPTH SWIMMING POOL/SPA - A variable depth swimming pool/spa can comprise a movable deck and a bottom. The movable deck can be movable relative to the bottom of a variable depth swimming pool/spa to provide for a variable depth of the portion of pool/spa that is accessible to a pool/spa user. The movable deck can be connected to the bottom of the variable depth swimming pool/spa via one or several legs. The one or several legs can be rotatingly connected to the movable deck and can be slidingly connected to the bottom of the swimming pool/spa. The rotational displacement of the legs can result in the vertical displacement of the movable deck. The legs can be connected to synchronizing arms that can interact with a synchronizing drive to coordinate the movement of a first leg with a second leg. | 08-28-2014 |
20140331398 | POOL FILTER SYSTEMS INCLUDING POOL 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 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. | 11-13-2014 |
20150107012 | SYSTEMS INCLUDING VARIABLE SPEED PUMPS FOR CLEANING SWIMMING POOLS AND SPAS - Systems and methods for circulating water of swimming pools or spas are detailed. The systems may include both a main filtration pump and a secondary booster pump, with the booster pump containing a variable-speed motor. By adjusting motor speed of the booster pump, pressurized water may be supplied to certain automatic swimming pool cleaners more efficiently, without need for energy-wasting by-pass paths or restrictor plates. | 04-23-2015 |
20150337552 | LAGOON TYPE SWIMMING POOL - A lagoon type swimming pool ( | 11-26-2015 |
20160002943 | Reciprocating In-Floor Pool Cleaner Head With Cover Flange - A device for use in a swimming pool includes an insert and a piston having a nozzle. The piston is carried in the insert for reciprocal movement between a lowered position and a raised position in which the piston is in one of a plurality of indexed orientations and the nozzle is above the insert. The piston rotates to an adjacent indexed orientation in response to reciprocation of the piston between the raised and lowered positions in response to the cyclical application of water through the insert. A flange on the insert covers a collar mounted in the floor of the swimming pool so as to conceal the collar from observation. | 01-07-2016 |

20160121345 | FLOW CONTROL DEVICES AND RELATED SYSTEMS - A flow control device includes a body having an inner and an outer surface that oppose each other. The body may have a first opening and a second opening spaced from the first opening along a first axis. The inner surface may define a passage that extends from the first opening to the second opening along the first axis. The body may also include an inlet port between the first opening and the second opening, and a constriction in the passage between the first opening and the second opening. The flow control device may also comprise a nozzle disposed at least partially in the inlet port and extend at least partially across the passage along a second axis that is angularly offset with respect to the first axis. The nozzle may define an exit port in the passage. | 05-05-2016 |
