A vehicle for conveying a rider within a tubular track comprises a support portion for supporting the rider and a retaining body adapted to retain the support portion against an interior wall of the tubular track. The retaining body has a sliding surface for slidable engagement with the wall of the tubular track. The support portion and the retaining body have a vehicle axis of movement about which the vehicle may rotate within the tubular track. An apparatus for transporting a rider comprises a tubular track having an interior wall and at least one vehicle.

Disclosed is a system for a combination bag, mat, and flotation device. The system includes an elongated mat having an external surface, internal surface, a mat section first side and second side, and a mat section first side and second side. A pair of flotation devices are attached to the mat section first side and second side. Each flotation device has an internal air compartment, inflation nozzle, and attachment element, and when inflated, allow the mat to be used as a flotation device. A first fastener being in attachment proximate to the mat section first side and a second fastener being in attachment proximate to the mat section second side. The first fastener and second fastener are configured to removably mate with each other. When the mat is folded so that the first fastener and second fastener are mated and the zipper is sealed, the mat forms a bag configuration.

The present invention is directed to an inflatable and floatable modular platform system wherein certain embodiments comprise an adjustable back-rest. The inflatable platform system of the present disclosure includes floating elements of differing shapes and sizes configured to be interconnected in order to allow users to stand, sit, and walk between floating elements. Embodiments include inflatable platforms having circular, arc-shaped, rectangular, and L-shaped inflatable platforms.

The present invention relates to two configurations of structure for a compact, pedal-propelled boat, a recumbent configuration and a conventional configuration, and to two possible propulsion systems, one with rigid transmission system and other with flexible transmission system. Both configurations are used with hulls arranged in parallel, catamaran configuration, preferably inflatable, allowing the volume and size of the assembly to be reduced so as to fit in a car trunk, making it easier to transport and store. In the recumbent configuration, the boat driver is in a sitting position, with his back supported by the seat, and actuates the pedals located in the front part of the structure while maneuvers the boat by means of handlebars located on the sides of the structure. In the conventional configuration, the boat driver is in the same position as the rider of a conventional bicycle, and the seat, pedals and handlebar are arranged in the same positions as in a bicycle. The invention seeks to provide simple solutions and the greatest quantity possible of shared components between these configurations, such that a production plant can produce these configurations through as few production processes as possible and sharing as many production processes as possible.

An inflatable stand up paddleboard, combined with a thermally insulated compartment is disclosed herein. The compartment may be used for storage of food, drink, personal effects, and other items that may require storage in a temperature stabilized medium. As constructed, the compartment and storage of items therein does not diminish the functionality or versatility of the inflatable paddleboard.

A configurable, adjustable inflatable device including one or more inflatable bladders and a shape-defining member that combines with the inflatable bladders such that an overall shape of the configurable inflatable device is at least partially controlled by the shape-defining member.

The present invention comprises a self-propelled craft with a U-shaped main body provided with two turbines, one on each flap of the U-shaped main body, which propel the self-propelled craft through turbine operation in a chamber fed by water received by water intakes which is ejected by the ejection openings, and which turbines move inside the turbine operation chamber adopting automatically one of two possible positions due to the casing which is placed in two different positions within the turbine operation chamber, which positioning results from the placement of the device on the water being done by side A or B, the water intake being done through existing water entrances on side A or B of the device.

Manually propelled water skis support a person skiing on water. The water ski includes a base having a binding on an upper surface and stationary propulsion structures with uniform height on the bottom surface. The propulsion structures include a rearward facing and vertical propulsion surface and a forward facing and sloped surface such that drag is greater when the water ski is moved rearwardly. The propulsion surface may be arcuate, V-shape, U-shaped, or other shaped in a horizontal plane and may also be circularly concave in a vertical plane. Buoyancy structures may be secured to the upper surface of the base forward and rearward of the binding. Water ski poles including elliptically- or cylindrically-shaped floats at the bottom ends may be used to provide a synergistic increase in waterskiing speed. Straps on the base near the binding may be used to secure the water ski poles to the base in order to form an outrigger.
