  • Patent number: 8550926
    Abstract: The present invention relates to an improvement in the construction of water ride surfaces and comprises at least one layer of soft permeable material built into the padded substrate of a structurally supported ride surface. The permeable material connects to a drainage system and is preferably sandwiched between a slick skin upper waterproof membrane, and a supporting substrate beneath it. The advantage to this improvement is when water leaks through the waterproof membrane, the permeable material prevents water from building up inside the padded substrate, and allows the water to be drained out, rather than blistering and bubbling up under the waterproof membrane, thereby helping to preserve the integrity and longevity of the ride surface.

  • Publication number: 20130199433
    Abstract: The invention relates to a positively buoyant wave generator adapted to travel through a body of water, wherein specific features are incorporated into the wave generator to help create and off-set various hydrodynamic forces that can act on the wave generator as it travels through the water. Rather than eliminating these hydrodynamic forces, the invention seeks to create and counter these forces, which has been found to help keep the wave generator in substantial equilibrium. For example, a connecting member can be extended forward and below the wave generator's center of buoyancy, such that as the wave generator is pulled, it creates an upward force that helps to counter a downward force acting on the front end of the wave generator as water is lifted up. Various internal moments can also be created and off-set by adjusting the center of gravity and/or center of buoyancy and using these forces to help keep the wave generator in substantial equilibrium.

  • Patent number: 8496403
    Abstract: The invention relates to a wave pool with a beach having a body of water and a wave generator that travels along a relatively shallow channel across from the beach. The wave generator is adapted to travel through the channel and displace the water in the channel to create primary waves on which surfing maneuvers can be performed. The primary waves in turn enter into the body of water to produce secondary waves that can be acted upon by the inclined pool floor so that they eventually break and spill onto the beach. The water in the channel is preferably provided with a reverse current to enable the absolute speed of the wave generator to be reduced, which allows the channel to be shorter in length without significantly impacting the wave effects that are created, which helps reduce the cost of construction.

  • Publication number: 20100125943
    Abstract: Disclosed is a method and apparatus for dampening waves preferably comprising a wave pool having two portions, a first wave forming portion with an inclined section oriented obliquely relative to the travel direction of the waves that causes the waves to begin breaking, and a second wave dampening portion having a relatively deep solid chamber floor and a raised perforated floor above it for dampening the waves after they begin to break. The properties of the raised floor, including its porosity, its depth (relative to the chamber depth), and the characteristics of the waves to be dampened, including the wave height and shape, are taken into account in designing a dampening system that substantially dissipates the waves, which in turn, reduces wave reflections and rip currents that can interfere with the next oncoming waves, and thereby, help to maintain quality surfing waves at high frequencies without increasing pool size.

  • Publication number: 20090191785
    Abstract: The present invention provides a miniature live-action surfing attraction and associated surf game specifically adapted for use with one or more surf toy action figures. The surf toy action figures are mountable to a surf board appropriately sized and weighted to provide relatively stable or semi-stable surf-riding action upon a sheet flow of water flowing up an inclined ride surface of the reduced scale attraction. Various surf action figures may be set free upon the ride surface, or they may be constrained or partially constrained by wires, strings, magnets or the like, as desired. Alternatively, or in addition, they may be controlled via a remote control, or radio control transmitter, as desired. Thus, a fun and entertaining game is created that provides realistic live-action surfing within a relatively small or confined area.
