| 20080251143 | FLEXIBLE VALVE ASSEMBLIES PRINCIPALLY FOR AUTOMATIC SWIMMING POOL CLEANERS - Flexible valves principally (although not necessarily exclusively) for automatic swimming pool cleaners are addressed. The valves have generally parabolic closure regions and do not present linear transverse cross-sections to water flowing through them. The closure regions may extend substantially below the transverse center lines of the valves, which additionally may include teeth at or near hinges of the closure regions. Including the hinges reduces likelihood of undesired wear at or near the outlets of the valves. | 10-16-2008 |
| 20080256727 | SWIMMING POOL CLEANER DISCS WITH POCKETS - Discs having recessed areas, or pockets, in their undersides are detailed. The pockets allow provision of increased suction in localized regions, especially useful when the body of an associated cleaner pivots from side to side. Downwardly-extending wear surfaces may be present as well within the pockets. | 10-23-2008 |
| 20090031508 | Automatic swimming pool cleaner discs and associated components - Separate covers for protruding portions of discs of automatic swimming pool cleaners are addressed. The covers may be placed onto protrusions, such as fins, and removed from the fins as needed. Version of the covers are made of material more rigid and having lower coefficient of friction than the fins to discourage lateral bending of the fins and decrease frictional contact of the fins with pool surfaces. | 02-05-2009 |
| 20090077759 | Pool Cleaner Hoses and Methods for Making the Same - Some embodiments of pool cleaner hoses and methods for making the same may include a flexible hose section associated with a pool cleaner that is flexible, but also able to resist substantial compression along its longitudinal axis. In some embodiments, the flexible hose section may be formed from a number of segments. | 03-26-2009 |
| 20100119358 | FLUID-POWERED MOTORS AND PUMPS - Fluid-powered devices are detailed. The devices may be utilized as motors or pumps, for example, and are capable to switching dynamically between these functions. They additionally may use surface-area, rather than solely pressure, differentials to produce rotary motion. | 05-13-2010 |
| 20100313363 | AUTOMATIC SWIMMING POOL CLEANERS AND BODIES, FEET, DISCS, AND OTHER COMPONENTS THEREOF - Devices for cleaning vessels, especially swimming pools, are discussed. The devices may include repositionable in-line valves, with the valves typically moving laterally (from side to side) and changing the initial direction of the main fluid-flow path through the valves and corresponding cleaner bodies. Asymmetric feet may be utilized as part of the devices, whose bottom bearing surfaces may include elongated strips of material placed parallel to the normally-forward direction of travel of the devices. Discs of non-uniform flexibility also may be employed, and blocking tabs or gripping material may be used to inhibit undesired backward movement of a cleaner when its operation commences. | 12-16-2010 |
| 20110089121 | DISPENSERS ESPECIALLY ADAPTED FOR USE IN VESSELS SUCH AS SWIMMING POOLS AND SPAS - Dispensers, principally of water-treatment chemicals, are detailed. The floating dispensers may be inherently unstable in use, rotating approximately ninety degrees (from a generally vertical position to a generally horizontal one) over the useful lifespan of the chemicals initially contained within. Movement of the dispensers to horizontal positions signals users to replace the depleted chemicals. The dispensers also may be stacked into smaller volumes for transit and storage and need not include a separate component for flow adjustment. Rotation of its components additionally may create a “dial-a-dosage” feature of the dispenser, effectively varying depletion rate of the chemicals contained therein. | 04-21-2011 |
| 20110226361 | IDLER MECHANISMS FOR HYDRAULIC DEVICES - Devices and methods for inhibiting movement of automatic pool cleaners (APCs) are described. Versions of the devices may cause pool water to bypass flowing through bodies of APCs. Alternatively, they may cause water flowing though bodies of APCs to bypass the associated motive force creators. The devices thus may constitute idler mechanisms, as they effectively prevent movement without requiring operation of the ultimate driver (i.e. the pump) to cease. | 09-22-2011 |
