Hendrikus Johannes van der Meijden has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20200011079
    Abstract: Buoyant, autonomous devices for actively scrubbing upstanding walls of swimming pools and spas at and nearby their waterlines are detailed. The devices may be configured to float on and travel along a surface of water of a pool and include at least one brush or scrubber adapted to contact pool walls. An electric motor may cause the scrubber to rotate about a shaft or axle, with frictional contact between the scrubber and the wall dislodging dirt and debris therefrom. In particular, if a scrubber is conically shaped and angled relative to the vertical direction, its rotating blades may lift water from the pool to hydrate dried debris stuck to the wall, thereby facilitating dislodging of the debris.

  • Patent number: 10480205
    Abstract: Components of automatic pool cleaners (APCs) are detailed. The components may include brushes configured to attach to blades of scrubbers of the APCs. The flexible brushes may rotate as their associated blades rotate and have fingers which flex so as to adduce contact between a to-be-cleaned pool or spa surface and bristles protruding outward from sides of the fingers.

  • Publication number: 20190203490
    Abstract: Automatic swimming pool cleaners and components thereof are described. The cleaners may provide dual filtration of debris suspended in water of pools as well as a fluid path allowing some water to by-pass one of the two filters. They also may include any of all components such as multi-section inlet tubes, Venturi jets, nozzles exhausting water onto rotatable vanes, brushes, downforce turbines, and mechanisms for adjusting water flow through thrust jets or sweep tails.

  • Patent number: 10337657
    Abstract: A tubular coupling comprising a first component (1) having a tubular male spigot (2) with a headed formation (3) on the outside thereof and extending towards one of its ends and a second component (5) has a socket for receiving the headed formation on the tubular male spigot in releasable manner. The second component has a flow passage (6) communicating with the socket generally collinearly with the tubular male spigot in the installed position. A seat (7) is provided in the inner surface of the socket so that it encircles an opening (8) where it communicates with the socket and the tubular male spigot has a resilient seal (9) for sealing an adjacent end of the tubular male spigot to the flow passage. The headed formation and socket are shaped to provide guide surfaces enabling introduction of the headed formation into the socket with the axis of the tubular male spigot extending transverse, typically at right angles, to the axis of a flow passage in the second component.

  • Patent number: 10316534
    Abstract: The invention relates to swimming pool cleaning robot (10) comprising: a body (11); at least one hydraulic circuit through which a liquid flows between at least one liquid inlet (13) and at least one liquid outlet (14), said hydraulic circuit including at least one means for separating debris suspended in the liquid; pumping means for driving the liquid through the hydraulic circuit; means for driving and guiding the cleaning robot on a surface; and means for controlling the operating parameters of the means for driving and guiding the cleaning robot (10). The control means comprise a pressure sensor (21) that can be used to determine the immersion depth of the cleaning robot in a swimming pool, and means for automatically controlling the measured pressure on the basis of a set value.

  • Publication number: 20190101394
    Abstract: Augmented (virtual) reality techniques are described for assisting in determining characteristics of swimming pools and spas. Such pools and spas may, for example, be mapped at least as to their general sizes and shapes. The mapped and other information may be available for display and may be furnished to an automatic swimming pool cleaner (APC) to improve its operational efficiency in cleaning the pool.

  • Patent number: 10092867
    Abstract: 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.

  • Patent number: 10030402
    Abstract: Swimming pool cleaners are detailed with filtration components attached at the rears of their bodies. At least some of the components may be external to a body, rather than within it, so as to provide greater surface area for filtered water to exit. They also may allow users to view the quantity of debris trapped in the filter without having to dissemble the cleaner. By contrast with many existing external filter bags, moreover, the components need not protrude materially above (or below) the heights of the bodies, hence avoiding creation of hydraulic drag as the cleaners move within pools, spas, or other liquid-containing vessels.

  • Publication number: 20180066444
    Abstract: Autonomous, mobile cleaners for water-containing vessels such as swimming pools and spas are detailed. The cleaners are especially useful for cleaning spas, although they may function adequately in connection with certain other vessels as well. They may be designed and constructed in particular to avoid high centering so as not to become stuck when encountering obstacles within the spas or other vessels.

  • Patent number: 9670687
    Abstract: Automatic pool cleaners (APCs) and components thereof are detailed. The APCs may turn feet, rather than entire bodies, to change direction and may provide water-flow paths through the bodies that are oriented vertically. Thus, unlike existing disc-based cleaners, the APCs may reduce influence of connected hoses on their movements within pools.
