Abstract: An apparatus for providing enhanced traction for an inflatable device is disclosed. The apparatus includes an inflatable gear assembly attachable to the inflatable device. The inflatable gear assembly defines an outside diameter that is greater than the largest cross-sectional distance of the inflatable device. The inflatable gear assembly and the inflatable device may be configured as totally integrated, partially integrated, or totally separated air chambers.

Abstract: Dynamic foot repositioning systems for a gliding board including a platform, having a top surface and a bottom surface, the platform including a foot receptacle disposed on the top surface of the platform, and a tether coupled to the platform with a distal end protruding from the bottom surface of the platform. The systems further include a guide track configured to slidably receive the distal end of the tether, the guide track defining a motion path over which the platform slides freely in response to forces applied by a user's foot while the gliding board is traversing a supporting surface. Related gliding board assemblies and methods for repositioning a user's feet are also described.

Abstract: A water toy includes a bumper ball having open ends and inner and outer walls separatable by an air space. Users enter and exit the ball through either or both of the open ends. The ball can be rotated by the occupant moving in one direction in it, as by walking. An open-ended cover, into which the ball is inserted deflated, contains fins on its exterior for interacting with water as the cover rotates when the ball is rotated. The cover also mounts a tow harness for connection to a boat tow rope, and the fins act to restrain spinning as the toy is towed through water.

Abstract: A jogging electric current generator which comprises a drum-shaped rotatable exercising unit operatively connected to an electric current generator. The drum-shaped unit is constructed so that a jogger can enter the unit and jog for purposes of exercising and also simultaneously therewith generate an electric current through operation of the generator. The jogging generator may be located closely adjacent to a dwelling structure so that one may leave a dwelling structure and immediately enter the jogging generator. The drum-shaped unit may also be constructed so as to operate as a water vane with water being moved during the jogging activity. A hand-held control unit may also be employed by the user of the apparatus.

Abstract: An aquatic exercise device for use in a swimming pool or the like comprising a substantially columnar-shaped, flexible buoyant body having a first and second end and partially encircles and supports the user's body and a substantially shank-type handgripping means integrally attached and projecting endwise outwardly above and below at the first and seconds ends of the substantially columnar-shaped flexible buoyant body thereby enabling the user to perform body movements in an aquatic environment similar to movements on land of walking, running, cycling, cross-country skiing, and calisthenics and further providing enhanced exercise intensity due to the aquatic resistance to movement of the user.

Abstract: A spherical recreational rolling cage comprised of at least three mutually orthogonal hoops is presented. The spherical cage includes an axle attached between two of the hoops and a rotatable seating assembly connected to the axle via a bearing whereby the seating assembly swivels freely relative to the spherical cage. Novel braking means, preferably of the disk type, and steering means are also incorporated into the rolling cage of the present invention.

Abstract: The vehicle comprises an element which forms a wheel, preferably a sphere 11 having an outer bearing surface and an inner bearing surface and, inside the wheel 11, an element which forms a preferably hemispherical car 1 for at least one passenger, said car 1 being adapted to slide along the inner surface of the wheel 11 when the latter rotates.
