Abstract: The present invention provides an aquatic towable vehicle that can be maneuvered by the rider to steer the vehicle and to put the vehicle in a controlled spin while being towed behind a boat. The vehicle includes a passenger deck having a convex lower surface, a lowermost center point, and elevated ends. Fins are attached to the convex lower surface spaced out from the center point, and symmetrically disposed with respect to the longitudinal center line of the deck and the center point. The body portions of the fins are elevated above the center point so they are out of the water when the vehicle is level in the water. A tow strap is attached to the convex lower surface at the center point. When the rider's weight is shifted to move the vehicle from the level position, the fins on one side of the center point engage the water and allow the rider to steer.

Abstract: Many people enjoy outdoor sports, both in summertime and wintertime. During the summer, water sports are very popular; during the winter, snow related sports come into season. Inflatable sports devices are particularly useful, as they can readily be transported from the user's home to the place of use. Whilst for many years, inflatable water sports devices have been known in the form of dinghies and rafts, only recently have these also been used in winter sports, such as sledging. The current invention, relates to an inflatable sports device, which is further integrated with guiding ribs provided on the underside of side regions of the device. In particular, these side regions are formed such that they do not continuously contact the underlying surface of the device, and therefore provide for enhanced steering control.

Abstract: A sports device (10), preferably a snow or water vehicle, has an outer shell (15) which when inflated, forms a support surface (13) underneath and a lying down or sitting surface (20) on top. An inflatable tubular shell (20) with two segments (21, 22) extending crosswise across it is provided in this outer shell (15). The outer shell (15) is formed of a robust fabric which is coated or laminated with plastic. The tubular shell (20), which is in itself separate from the outer shell, is produced from plastic films, preferably without any fabric reinforcement. The outer shell may also be connected to the tubular shell in such a way that they form a single film. The sports device can therefore be produced with optimal materials for the outer shell or the tubular shell, with the result that it has a long service life.

Abstract: An inflatable water sports board, including two parallel adjacent flexible panels. The panels have a front portion parallel to the rest of each panel. The panels also have perimeters connected by a sidewall adherent to the perimeters all the way around the perimeters, enclosing an air chamber. The distance separating the panels is upwardly limited by drop stitches between the panels throughout the air chamber. An inflation port is installed in one of the panels. When the board is inflated, air pressure in the air chamber pushes the panels outward, against the restraint of the stitching, rigidifying the panels sufficiently to support an adult human, while maintaining a shape suitable for use in surfing. The surface of the inflated board remains sufficiently elastic to be unlikely to cause injury by impact. The board may include an attached leash with bracelet for retention. When deflated, the flexibility of the panels allows the board to be rolled up or folded for easy transport or storage.
