| The present invention provides a personal propulsion device including a body unit having a center of gravity, where the body unit includes a thrust assembly providing a main conduit in fluid communication with at least two thrust nozzles, with the thrust nozzles being located above the center of gravity of the body unit. The thrust nozzles are independently pivotable about a transverse axis located above the center of gravity, and may be independently controlled by a single common linkage. The present invention may further include a base unit having an engine and a pump, which provides pressurized fluid to the body unit through a delivery conduit in fluid communication with both the base unit and the thrust assembly. | ||||||

| The rudder is comprised of a planar body wherein a large front notch and a rear notch form two lobes or side wings which are perfectly symmetric with respect to the front-to-rear axis. On the axis and at the vicinity of the front notch is provided the unique point of towing, variable through a movable part, to which is fixed the corresponding towing rope. On each side wing, there are arranged, symmetrically and forward of the towing point, two windows that the user can grip with his or her hands and, behind the windows, in the lower part of the device and also in a symmetrical arrangement there are provided two rudder-like fins. The apparatus can be gripped manually with the arms extended forward allowing a swimmer-diver to move on the water or in the water. | ||||||

| Apparatus for supporting the human in water includes floats for resting on the water and a structure for supporting the human. A structure is affixed to the floats and the human can use his feet or fins attached to his feet for moving the apparatus in the water. The floats can be two elongated members spaced to either side of a space for accommodating humans or can be at least partially circular to partially surround the human. | ||||||
| 45 | Swimming frame | US505171 | 1990-04-05 | US5041031A | 1991-08-20 | German S. Genfan |
| A swimming frame for competition in swimming, swimming instruction, muscle strengthening, and entertainment in the water comprises a pair of floats (1), a clamping unit (2, 3), and a paddle unit (4, 5, 6). It might be used by everyone regardless of the ability to swim. The paddle unit might by modified giving an additional possibility to practice butterfly-like and crawl-like style of swimming. A swimmer being clamped between rigid (2) and flexible (3) portion of the clamping unit is producing the push-pull movements of the paddle unit. When he pushes the unit, the paddle (4) is rotated up to horizontal position by the water pressure against its front. When he pulls the unit, the paddle is rotated up to vertical position by water pressure against its back. Because of the difference in the paddle hydroresistance between push and pull movements the swimming frame will be propelled by the swimmer. | ||||||
| 46 | Swimming device | US865288 | 1977-12-28 | US4158245A | 1979-06-19 | Robert K. Cunningham |
| A swimming device has a body platform with straps for the arms and body of a swimmer. Cylinders extend longitudinally on the platform and are open at their forward ends and have restricted outlet nozzles in the rear. Pistons are slidably mounted in the cylinders, and cables are secured to the pistons and to foot stirrups. The pistons are provided with flapper valves which open to permit fluid passage upon forward propulsion of the piston, and close to prevent such passage when the piston is on its backstroke, thereby forcing a water jet from the piston to propel the platform and swimmer forward. | ||||||
