The invention relates to a covering device for liquid tanks, in particular swimming pools, comprising a buoyant covering element, the covering element comprising a continuous covering layer and a fluid chamber connected to the covering layer, a pumping being provided, which is designed to convey a liquid, in particular water, and/or a gas, in particular air, into the fluid chamber. The invention also relates to an assembly of a covering device according to the invention together with a liquid tank.

A wave generating apparatus mobile application controller and method are provided in which a mobile controller actuates a plurality of wave generating chambers in sequence using a delay between the actuation of each chamber to produce a rideable wave in a pool. The mobile application controller allows the user to select the exact type of wave to be produced by the wave generator apparatus by selecting the size, shape, and pattern of the wave. The application also allows the user to use a camera to photograph or record herself or someone else, even while riding a wave.

Disclosed embodiments may include a trampoline scooter device for practicing scooter tricks on a trampoline. The device may include a foam deck with an upper surface and lower surface, where the upper and lower surface both contain a recess. The recesses are designed to receive, respectively, an upper attachment member and a lower attachment member. The upper and lower attachment members and the recesses contain aligned holes to receive connectors. The connectors, or bolts, extend through both attachment members and the deck to secure the deck to the attachment members using nuts. The upper attachment member is connected to the headtube of the scooter via the neck. The headtube contains connections to the column. The column is attached to handlebars containing grips and grip ends.

Disclosed embodiments may include a trampoline scooter device for practicing scooter tricks on a trampoline. The device may include a foam deck with an upper surface and lower surface, where the upper and lower surfaces both contain a first recess. The first recesses are designed to receive, respectively, an upper attachment member and a lower attachment member. The upper and lower attachment members and the recesses contain aligned holes to receive connectors. The upper attachment member is connected to the headtube of the scooter via the neck. The headtube contains connections to the column, which is attached to handlebars containing grips and grip ends. The foam deck may include one or more deck weights at the end of the foam deck opposite the attachment members, either embedded within the deck, or within a second recess of the upper and lower surfaces. The foam deck may include a spine support.

Enhanced surfing by means of waterproof gloves which provide lifting pads spanning the width of the palm from the base of the thumb and terminating near the pinky, or also extending across the upper palm finger pads if desirable, while secured tightly at the wrist. The padding is contoured and rises to prescribed height starting at the base of the wrist, rising to the maximum height near the base of the palm, and then returning to ‘level’ with the hand inside the palm. Similarly, narrower finger pads will follow a similar contour but will have less height than the palm pad. The padding provides a resilient, rebound boost to aid surfers in quickly rising to their feet while simultaneously creating more clearance between a surfer's torso and board to allow for a heightened swing arch to create forward distance for initial foot positioning and added takeoff momentum.

A training harness system for snow sport training includes: a training harness that is wearable by a student, including: a harness body with a central leash receiving structure and left and right leash connector assemblies, each including at least one leash receiving structure with an elongated aperture; and a leash assembly, including first and second leashes, each including: an elongated leash member; a leash handle; and a leash connector with a hook portion, that includes an elongated hook member, such that the elongated hook member detachably connects with the at least one leash receiving structure; such that the training harness system enables a trainer to control and guide skiing or snowboarding of a student. The training harness system is configurable for beginner, intermediate, and advanced students, with different connections of the right and left leashes to the training harness.

An apparatus and method of using the same for simulating surfing skateboarding, snowboarding or the like. The apparatus comprises a platform capable of supporting a user such as a continuous elastic surface such as trampoline or similar. A support is coupled to the platform for holding the platform. The apparatus further comprises a bearing or similar assembly coupled to the support for allowing the platform to rotate about an axis which is displaced a distance from the user while standing atop the platform during simulation thus simulating bottom and top turns. The apparatus further comprises a stand coupled to the bearing for securely supporting the bearing and tilting the axis of rotation.

Skateboard training devices are provided to assist all levels and ages of skateboard enthusiasts in learning tricks. The devices can comprise a deck including a core comprising a set of materials, wherein the core is partially or entirely surrounded by an outer protective material. In some aspects, the core can be made of one or more of a wood, a plastic, a metal, a composite, a fiberglass, and nylon. In some aspects, the outer protective material comprises a foam material. In some aspects, the core can comprise a foam material that is denser than an outer protective foam material.

A wave generator pool that may be used for surfing, which has reefs configured to provide a variety of novel wave shapes. Reefs may have multiple sections with varying angles, causing the shape or direction of the wave to change as a surfer rides the wave. One or more embodiments of the pool may have two basins that share a common wave generator, resulting in substantial energy savings. An illustrative dual basin pool may have an intermediate basin on one side and a beginner basin on the other. The intermediate basin may have an easy takeoff reef section with a reef angle between 65 and 85 degrees. The beginner basin may have several isolated takeoff reef sections where a corresponding number of surfers can await a wave. Reefs may be constructed and reconfigured using a modular reef structure that avoids the months of downtime associated with rebuilding fixed reefs.

A wave generating system is provided. The system includes an enclosure having a base and plurality of sidewalls extending orthogonally upward from edges thereon, wherein a plurality of pistons are disposed over the surface area of the base therein. A covering layer of a waterproof and flexible construction is pivotally affixed to a top end of the plurality of pistons and attached to the plurality of sidewalls. The plurality of pistons is operably connected to a circuit board disposed within a control panel via a grid connection and programmed to create patterns and contours in the covering layer via the plurality of pistons. The patterns of ocean floor conditions ideal for surfing, as well as other geometric patterns, may be programmed and operated using a display screen or remote control.
