Patent number: 5921834Abstract: 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.Type: GrantFiled: December 14, 1994Date of Patent: July 13, 1999Assignee: Douglas Builders, Inc.Inventor: Douglas D.

Patent number: 5243224Abstract: 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.Type: GrantFiled: February 3, 1992Date of Patent: September 7, 1993Inventor: Lee Tagney, Jr.
