  • Patent number: 4580988
    Abstract: A float (10) is disclosed for providing vertical, side-to-side and front-to-back support to a user. Float (10) includes a seat (11) for supporting the user in a pre-determined astride, sidesaddle or reclined position. First and second buoyant elongate body supports (20 and 21) are each secured by a hinge to opposite ends of seat (11). The body supports (20 and 21) support opposite sides of the torso of the user depending upon the manner in which the user sits on the seat. The body supports (20 and 21) are freely and independently moveable about their respective hinges (12 and 13) within a relatively wide angle of travel to permit adjustment to varying body positions and movements. According to one embodiment of the invention, auxiliary stabilizing floats (33, 34 and 39, 40) are telescoped within bores (30 and 31) of the body supports (20' and 21'). By extending the auxiliary floats (33, 34 and 39, 40) greater resistance to side-to-side or front-to-back tipping is provided.
