  • Patent number: 5411425
    Abstract: A floatation unit comprised of a generally rectangular air bag, and having an inflation hose and valve, is disclosed. Four grab loops project from the four corners of the air bag, two of the corners also including hooks for engaging a water craft's gunwale, the other two of the corners including cinch straps. A pair of the floatation units is used to stabilize a water craft by engaging the hooks of each to opposing gunwales of the craft, and tensioning their cinch straps beneath the craft. A pair of floatation units is also used to displace space with a water craft, thereby reducing its likelihood of sinking if swamped. For displacement, each of the pair of units is hooked to a thwart within the water craft, and their cinch straps are tensioned between them to suspend the units securely between the thwarts. A pair of the units may also support a seat panel between them, the seat panel having corner loops through which the cinch straps pass.

  • Patent number: 5090695
    Abstract: An exercise float platform is formed of specifically dimensioned buoyant sections connected by flexing hinges to permit a user to perform an exercise routine in an aquatic environment. The buoyancy of the individual sections can be selectively adjusted depending on the weight distribution of the individual, or the exercise routine intensity. The exercise float permits the user to perform exercise routines in the water focused on the back, hips and stomach muscle groups along with allowing flexible upper and lower body workouts while either sitting below the water level or reclined above the water level.

  • Patent number: 5020465
    Abstract: A flotation apparatus such as an inflatable tube is designed for a wide sluice waterslide. A coupling for the tube has a prong on the bow of the tube, which is V-shaped, the prong extending forward along a handle portion and downward to a distal locking knob with radial fins. A positioning plate reinforces the coupling between the prong and a mounting plate on the tube. A coupling ring is attached to the mounting plate or the positioning plate, laterally of the prong, and a second coupling ring is provided at the stern of the tube, such that the tube can be coupled to other such tubes in single file or face to face arrays. The fins of the prong and the inside diameter of the rings are complementarily conical in the insertion and removal directions. A wide sluice waterslide to be traversed by the tubes as joined in lines or arrays has a generally downhill contour along a sinuous path.

  • Patent number: 5006082
    Abstract: An actuating device for small inflatable rafts or articles comprising a jaw clip for securing the device to the article, the clip having a top plate with solar cells mounted on the jaw clip upper rim, and a housing mounted to the jaw clip bottom.The solar cell plate produces electric currents via sunshine, and a rechargeable battery in the housing is charged with electricity. The battery serves as a power source for an air pump in the housing to generate air pressure to inflate a raft or other article. The battery also serves as the power source for a motor in the housing which drives propellers on its output shaft thereby providing a means to propel the inflated raft or article in the water.

  • Patent number: 5000710
    Abstract: A deep water exercise belt, which supports the user in deep water in an upright, running position so as to allow vigorous exercise without placing body weight on the legs, involves a waist encircling belt of flexible buoyant material of uniform thickness which is shaped to provide greater flotation at the back of the user. Shaping includes an increased width of the belt on the back while forming the bottom of the belt to avoid hip motion of the user. The belt may be constructed of a chemically cross-linked polyethylene having an extremely fine closed-cell structure. The interior surface of the belt is smoothed so as to provide a suction effect against the body, while the exterior surface may be roughly textured to provide additional resistance to movement through water. A separate band of elasticized material is intertwined through the buoyant belt so as to buckle at the front of the user and hold the exercise belt in close contact with the waist.

  • Patent number: 4993980
    Abstract: An exercise device comprising a flotation jacket worn by an exerciser in water which enables the exerciser to float in an upright position while exercising and without contact with the bottom or sides of the enclosure holding the water. The jacket is fabricated from a fabric with pockets sewn in the fabric for insertion of segments of flotation material. The size and location of the segments result in equal buoyant forces at the front and back and at the sides of the exerciser to assure that the exerciser remains upright while floating in water. The fabric is such that the friction between the flotation jacket and the exerciser is increased when the fabric is emersed in water thereby preventing the jacket from riding up under the armpits of the exerciser. The flotation jacket can be fabricated easily and at low cost by using standard materials and production techniques without the need for expensive molding equipment.

  • Patent number: 4986786
    Abstract: A garment for use in water recreation in the form of a unitary flat member generally of a figure-8 construction having a front portion and a back portion, the portions being connected by a narrow crotch portion, the member being of soft, flexible and floatable material, such as closed cell foam plastic, and fasteners affixed to the front and back portions, the member being wearable by a user in which the crotch portion is positioned between the legs of the user and with the front portion in contact with the user's abdomen and the back portion in contract with the user's buttocks and lower back so that the garment floats the user in a generally upright or seated position.

  • Patent number: 4968278
    Abstract: A flotation platform is set forth comprising a first chamber of a first width underlying a superimposed upper chamber of a second width substantially twice the width of the lower chamber to enable selective inflation of the upper chamber to accommodate and effect comfort to a user while enabling inflation of the lower chamber to an elevated pressure to maintain stability of the platform. The platform further includes a perimeter cord integrally secured at the junction of the upper and lower chambers and positioned within an arcuate recess coextensive with the cord wherein the cord is of a cross-sectional area greater than the wall thickness of either lower or upper chamber. The cord anchors a series of forward handles at a forward wall of the platform and a series of lower handles at a lower series of platform to rigidly secure the handles to the cord and the platform. Each handle is provided with a spring-biased clip to enable a user to rapidly secure a tether line to the clip in lieu of the handle.

  • Patent number: 4932912
    Abstract: Aquatic recreational apparatus providing in an integral structure a kick board and manually operable means for directing a stream of water toward a desired target is described. The apparatus in its preferred embodiment takes the form of a smooth, contoured kick board having dual, laterally spaced handles and integral therewith trigger means for manually operating corresponding pumps. A pair of first fluid conduits extends from dual, laterally spaced inlets located in a rearward region of the kick board to first sides of the pumps, and a pair of second fluid conduits extends therefrom forwardly to laterally spaced nozzles in the extreme forward region of the kick board. The laterally spaced handles provide a secure grip to the user whose upper body is supported by the kick board, while the user maneuvers the kick board by pedal action into a position suitable for directing a stream of water from the body of water in which the kick board is being used toward a desired target remote from the apparatus.
