  • Patent number: 10378225
    Abstract: The present invention is an artificial surfing reef for modifying a body of water's bathymetry to create surfing waves. The artificial surfing reef is a shaped structure made up of many sized and shaped Expanded Polystyrene Geo Foam blocks. As swell moves toward the shore, its bottom is resisted by the leading edge of the Expanded Polystyrene Geo Foam artificial surfing reef. As the swell transverses over the Expanded Polystyrene Geo Foam Artificial reef, the wave topples over and forms a plunging surfing wave. An earth anchor, connected to a cable, linked to a round shaped anchor disc, is attached to each Expanded Polystyrene Geo Foam block for maintaining the foam artificial reef at a desired location submersed underwater. A plurality of Expanded Polystyrene Geo Foam blocks may be attached to one another and configured so as to define a surf reef, which enhances the suitability of waves for surfing.

  • Publication number: 20130205490
    Abstract: A safety device for a drain sump includes a drain adjunct member and an adapter for attaching the drain adjunct member to the main drain pipe that is in connection with the pool or spa pump. The drain adjunct member is “T-shaped” for limiting the possibility of limb entrapment and further includes anti-hair entangling mesh and vacuum relief holes for limiting the possibility of hair and body entrapment. In the event that an individual does block water flow into the drain adjunct member, the unblocked vacuum relief holes prevent a vacuum force from being created by allowing increased intake of water therethrough. The arrangement of the vacuum relief holes on the body of the drain adjunct member disrupts the vortex effect otherwise created by the typical single direction flow of water in a standard main drain pipe, thereby further limiting the likelihood of limb, body or hair entrapment.

  • Publication number: 20120297531
    Abstract: Anti-entrapment drain cover [A] for pools is formed by a molded wheel-like cover unit [10] of radial dimensions greater than the radius of any pool sump or drain [10] to be covered, so as to extend over the drain floor radially beyond the drain. Radial ribs [14] below the cover unit define channels opening at the periphery to provide a side inlet [18] between each rib pair so that the periphery stands off the surface sufficiently for water flow through the inlets but with spacing insufficient for user grasping of the cover. Arcuate inlet recesses [20] open periphery between rib pairs, so water flows into the channels for draining without potential for pool user entrapment even if a pool user attempts to block them. Securements are such that the cover, which is user unbreakable, cannot be pulled away by the user.

  • Patent number: 7784117
    Abstract: A vacuum relief safety valve includes a housing defining an inner chamber and attached to the suction-side of the swimming pool or spa pump. An air inlet aperture is formed in the housing so as to be open to ambient air. A sealing element is disposed within the housing and biased against the air inlet aperture by a spring so as to effectively seal the inner chamber of the housing from ambient air. When a maximum allowed vacuum level within the pump is exceeded, such as when a swimming pool drain is obstructed, the sealing element moves into the inner chamber and opens the air inlet aperture causing the pump to rapidly lose its prime and enabling removal of the entrapment. Simultaneously, the movement of the sealing element provides electricity to a control circuit which shuts off power to the pump.

  • Patent number: 7614094
    Abstract: A machine and method for anticipatory sensing and intervention to avoid swimmer entrapment, entanglement or evisceration; with a proactive, pre-entrapment, ultrasonic sensor assessing the relative hazard of swimmer proximity to a drain cover. A transducer launches waves into the suction piping and/or drain system, and receives echoes from the drain cover, swimmer limbs, hair or body, and water or wall surface parallel to the drain cover. A transmitter electrically energizes the transducer launching waves into the suction piping and/or drain system. A receiver/processor detects the echoes analog signals from the drain cover and water beyond the pool drain. A Logic and Control element converts the detected signals into reliable information regarding safety/hazard status for a swimmer near a drain. Predetermined logic provides automatic pump shutdown, and alarms as required; including a missing drain cover. A pool alarm mode detects that an object, such as a small child, has fallen in.

  • Publication number: 20090064403
    Abstract: A machine for anticipatory sensing and intervention to avoid swimmer entrapment, with an active pre-entrapment sensor (e.g. ultrasonic) that assesses the relative hazard based on swimmer proximity to the drain cover. An Ultrasonic Transducer launches waves into the suction piping and/or drain system, and receives echoes from the drain cover, swimmer limbs, hair or body, and the water surface parallel to the drain cover. A Transmitter/Pulser electrically energizes the ultrasonic transducer to launch waves into the suction piping and/or drain system, A Receiver/Processor detects the echoes electrical signals from the ultrasonic transducer. and receives echoes from objects of interest beyond the pool drain. A Logic and Control element converts the detected signals into reliable information regarding a swimmer safety/hazard status. An Output provides a pump shutdown command when required. There is also a pool alarm mode to detect, and a panic alert, that a child has fallen in.

  • Patent number: 7493913
    Abstract: A vacuum relief safety valve includes a housing defining an inner chamber and attached to the suction-side of the swimming pool or spa pump. An air inlet aperture is formed in the housing so as to be open to ambient air. A sealing element is disposed within the housing and biased against the air inlet aperture by a spring so as to effectively seal the inner chamber of the housing from ambient air. When a maximum allowed vacuum level within the pump is exceeded, such as when a swimming pool drain is obstructed, the sealing element moves into the inner chamber and opens the air inlet aperture causing the pump to rapidly lose its prime and enabling removal of the entrapment.

  • Publication number: 20090019633
    Abstract: An apparatus and system are disclosed for a pool drain cover, the cover having a perforated ramp around its perimeter to which are attached a plurality of straight, horizontally disposed tubes, circumscribing channels with substantially continuous cross-sectional areas, each tube enclosing a channel extending the length of the tube of at least six inches. The cross-sectional area of the tubes is kept at a minimum and their number is increased by arranging the tubes in rows and columns or giving the tubes an elliptical cross-sectional area and arranging them in a single row, thereby reducing the tapering in the tubes. The cover may be segmented and may be of multiple shapes, including a circle.

  • Patent number: 7389573
    Abstract: The installation and removal of a portable but sturdy pool barrier fence uses the hardware installed for attaching a safety pool cover during the pool use season. Multiple rectangular panel frames support a mesh fabric. Each panel has a lower horizontal frame member with a series of slots accommodating the same fastener used to attach the pool cover coupling during the off-season. Sections of fencing panels are attached together using bi-fold hinges, which permit 360 degree rotation of one panel relative to an adjacent one. This allows storage of the barrier fence as a dense rectangular three dimensional unit by folding the panels upon each other accordion-like. Sections of fencing panels are joined together to form respective fence units to form the fence around the pool.

  • Patent number: 7346938
    Abstract: A safety cover having a filter and an optional chemical dispenser, that covers and existing faceplate on a water vessel having a closed loop piping system and water pump. When the cover and filter cover an existing faceplate the cover and filter increases the vacuum on a suction line leading to a water pump by less than 5? Hg. The chemical in the dispenser releases in a metered dose of a substance having antimicrobial properties and the dose is in a sufficient amount to inhibit a growth of a microorganism in at least a segment of a water vessel. The combination of cover, filter and chemical chamber are disposable, or the filter is replaceable and the chemical in the chemical chamber is replenishable. The cover with filter and chemical chamber or just the cover and chemical chamber, or just the cover and filter are retrofitable to any existing faceplate on a water vessel having a closed looped piping system and a water pump.

  • Patent number: 7213275
    Abstract: A hydraulic suction fuse is mounted in a conventional debris collection trap of a swimming pool, spa or the like, to significantly reduce or eliminate any suction force on the bottom or side wall mounted drain of the swimming pool, spa or the like, as a result of the drain becoming essentially wholly covered by a body part of a person or other drain clogging article. Alternatively, the hydraulic suction fuse may be mounted in a compartment in line between the drain and a suction pump of a swimming pool, spa or the like. Thereby, a person captured by the suction force at the drain will be released and the person is free to move away from the drain essentially instantaneously upon contact with the drain. The hydraulic suction fuse is self resetting once inflow through the drain is no longer restricted.
