210167180 | Skimmer arm at skimmer opening at water surface | 6 |
20100155317 | POOL SUCTION VALVE - A valve system for insertion between a cleaner hose and a pool suction line is mounted in a wall of the pool or skimmer box and comprises a valve with a gate pivoted in a housing which receives the end of the cleaner hose when the gate is open which is thereby juxtaposed in line with the pool suction line located in the pool wall or skimmer box. The juxtaposed ends of both the cleaner hose and the pool suction line have mating tapers and the valve rotates so that the tapered end of the inserted cleaner hose rotates into sealing engagement with the tapered end of the pool suction line. Further the gate of the valve closes automatically when the cleaner hose is withdrawn. | 06-24-2010 |
20120222997 | Power Supplies for Pool and Spa Equipment - Power supplies for pool and spa equipment are disclosed. In one embodiment, the power supply includes a buoyant housing, a peripheral float, at least one solar cell positioned on the buoyant housing for collecting sunlight and converting same to electrical energy, and a power cable for interconnecting the power supply and pool/spa equipment. In other embodiments, first and second inductive power couplings are provided for powering pool and spa equipment. The power couplings can also be installed using existing plumbing features of the pool or spa. | 09-06-2012 |
20140202941 | WHIRLPOOL SKIMMER - A whirlpool skimming device removes surface debris from a pool by creating a whirlpool having an upper bound at the surface of the pool. The uppermost portion of the whirlpool is free standing and is not bounded by the device. The device includes an outer cup-shaped portion and an inner cup-shaped portion coaxially disposed therein. An opening is disposed in the bottom of the inner cup-shaped portion which communicates with a source of suction which is preferably a Venturi tube feeding the outlet water to a filter bag. There is a first nozzle supplying water at an upper, inner edge of the inner cup-shaped portion at a slightly downward angle in a first direction, and there is a second nozzle supplying water at a lower, outer edge of the inner cup-shaped portion and mounted on an opposite side of the inner cup-shaped portion. The device causes coaxial rotational flow patterns relative to the inner cup-shaped portion, in which the outer rotational flow takes an upwardly spiral path outside the inner cup-shaped portion, and the inner rotational flow takes a downwardly spiral path inside the inner cup-shaped portion of the device. | 07-24-2014 |
20150308137 | Flow Diverting Weir for a Swimming Pool Skimmer - A flow diverting weir device includes a mounting member having a length thereof sized to fit under a compression and without use of fasteners into a skimmer opening of a swimming pool skimmer, and an arm having one end thereof fastened to the mounting member, the arm movable between a coiled position and an uncoiled position, wherein the arm extends outwardly from the skimmer opening in the uncoiled position. Arm may be manufactured form a flexible material and have an arcuate cross-section in a plane normal to a length thereof. | 10-29-2015 |
20160040445 | AUTOMATIC SWIMMING POOL CLEANER CONCEPTS - Described are cleaning devices intended for immersion in water of swimming pools and spas. The devices beneficially may be pressure-side cleaners attached indirectly to outlets of water-circulation pumps. The supply of pressurized water travelling from a pump to such a device may be employed for various purposes, including directing debris-laden water to or near tops of debris collection chambers. The water exiting nozzles associated with the devices may push, rather than pull, the debris-laden water toward the collection chambers. Some nozzles may be oriented approximately parallel to a to-be-cleaned pool surface, and curved tubes may be employed to direct water and debris flow to perimeters of the cleaners. | 02-11-2016 |
20160123030 | SWIMMING POOL FLOW DIVERTING WEIR - A flow diverting weir device includes a mounting member engageable with surface(s) of a skimmer opening of a swimming pool skimmer and an elongated arm having one end thereof connected to the mounting member and extendable outwardly from the skimmer opening. The mounting member may be integrated into the surface(s) of the skimmer opening. The mounting member may include suction cup(s). | 05-05-2016 |
