DETAILED DESCRIPTION—FIGS. 1A AND 1B—PREFERRED EMBODIMENT
A rider 10 (FIG. 1A) lies on a towing flotation platform 12A made on the base of a Ski Tube (further in the text: “Ski Tube”) which is connected to a tug 14A by means of a tow line 16A. The Ski Tube 12A is equipped with nozzles 18 directed downward located above the water's surface and mounted on both sides by means of brackets 20. The nozzles 18 are connected with an inlet port 24 (made in the shape of a conical contraction) by a hose 22 (mainly made of lay flat discharge hose). The inlet port 24 is attached to the tow line 16A by means of a tether 26 and supported at the submerged position by a spoiler 40 and a float 28.
The inlet port 24 (FIG. 1B) may also be attached directly to the Ski Tube 12A by ball joint arms 42. It is also connected to the nozzles 18 by the lay flat discharge hose 22, but the Ski Tube is connected to the tug 14A by the tow line 16A.
Operation—FIGS. 1A, 1B and 1C
The Ski Tube 12A (FIG. 1A) is towed by the tug 14A by means of the tow line 16A. When the tug 14A reaches a speed by which kinetic head at the inlet port 24 is sufficient enough to produce the needed pressure inside the hose 22, water is discharged at the nozzles 18 making a thrust sufficient enough to lift the rider 1 off the water's surface. Regardless of the height of the Ski Tube 24 above the water's surface, the inlet port 24 should be submerged. This is achieved by means of the spoiler 40 (anti-wing) which is connected to the tether 26. In order to prevent a vertical load from the tow line 16A (due to the volume of the lift force) the depth of the inlet port is limited by the float 28.
The apparatus shown in FIG. 1B works analogously to the apparatus in FIG. 1A. Owing to the ball joint arms 42, the inlet port 24 (together with the arms) can be folded in the direction of the Ski Tube (FIG. 1C) for compactness during transportation.
DETAILED DESCRIPTION—FIGS. 2A AND 2B—ADDITIONAL EMBODIMENT
A flotation platform 12B (FIG. 2A) is made in the shape of a Backpack (further in the text: “Backpack”) equipped with nozzles 18 mounted on both sides. The nozzles 18 are connected to the inlet port 24 by lay flat discharge hose 7 which pass behind the rider 10. The inlet port 24 is hang from the tow line 16A by means of a tether 26 and supported at the submerged position by a spoiler 40 and a float 28.
For the Backpack 12A (FIG. 2B), water-supply of the nozzles 18 may also be realized by means of the inlet port 24 fixed on the rider's feet. The inlet port 24 is connected to the nozzles 18 by the lay flat discharge hose 7 and is also connected to the tug 14B by the tow line 16A.
Operation—FIGS. 2A and 2B
The rider 10 (FIG. 2A) puts on the Backpack 12B, which can be combined together with a life jacket. While been towing the rider 10, due to a lifting force (which appears analogous as said above), assumes a vertical position, so the rider moves as if stand on his/her feet on the water's surface.
The apparatus shown in FIG. 2B works analogously to the apparatus in FIG. 2A. Owing to the connection of the inlet port 24 to rider's feet and to the tow line 16A, it is not necessary to install the spoiler 40 and the float 28.
DETAILED DESCRIPTION—FIG. 3—ADDITIONAL EMBODIMENT
In any version of flotation platform (for example the Backpack 12B) (FIG. 3), water-supply of the nozzles 18 is realized by means of a water pump 30 equipped with a rotational swivel fitting 32 and stationary is mounted in a reservoir (for example in a pool 14). The water pump 30 is connected to the nozzles 5 by means of a tow line 16B made in the shape of a hose.
Operation—FIG. 3
The pump 30 (FIG. 3) supplies (by pressurized water) the nozzles 18 through the tow line 16B, so the tow line also acts as a water-supply pipe. The rider 10 moves around the pump 30 owing to rotating swivel fitting 32. This can be implemented at various populated areas and attractions—for example water-country, seaward, etc. as the pump may be mounted in a pool, lake, or pond.
DETAILED DESCRIPTION—FIG. 4—ADDITIONAL EMBODIMENT
In any version of the floating platform (for example the Backpack 12B) (FIG. 4) water-supply to the nozzles 18 is realized by means of the water pump 11 mounted on a tug 14B. The water pump 30 is connected to the nozzles 18 by means of a tow line 16B made in the shape of a hose. The tug 14B is unmanned and has remote control propulsion 38 (including the derived water pump 30) controlled from the steering handle bar 36 mounted on the Backpack 12B.
Operation—FIG. 4
The rider 10 (FIG. 4) remote controls the unmanned tug 14B. The propulsion 38 also drives the water pump 30, connected to the nozzles 18 by means of the hose 22, so the hose performs a function as the tow line 16B. In the other version containing the kinetic head inlet port water-supply, the pumping water-supply system does not require a top speed from the tug. The apparatus can practically be all in the air even while the tug remains motionless.
DETAILED DESCRIPTION—FIG. 5—ADDITIONAL EMBODIMENT
The water pump 44 (FIG. 5) is mounted directly on the Backpack 12B, so the pump performs like a motor pump controlled from the steering handle bar 36, also mounted on the Backpack 12B. The pump outlet is joined with nozzles 18, but the pump inlet is connected to inlet port 24 (located under the water's surface) by the hose 7.
Operation—FIG. 5
The rider 10 (FIG. 5) puts on the Backpack 12B and controls the motor pump 44 by means of the steering handle bar 36. Water comes in through the inlet port 24 and discharges through the nozzles 18 by the motor pump 44.
CONCLUSION, RAMIFICATION, AND SCOPE OF INVENTION
In all the versions of the apparatus the center of thrust (located at the center of nozzle) is above the center of gravity (located at low point of human stomach). The positive distance between the center of thrust and center of gravity assures the vertical stability of the rider's body.
In all the versions of the apparatus the nozzles can be mounted with the possibility of independent rotational motion and operated by means of the steering handle bar, so the rider can change the direction of thrust for maneuverability.
Parameters of the real apparatus for rider weight of 175.0 lbs (80 kg) should be approximately: the tow speed—15.0 knots (31.0 km/h), the inlet port diameter—5.0″ (125.0 mm), the hose diameter—3.0″ (75.0 mm), the nozzles diameter—2.0″ (50.0 mm).
The technical solutions, described above, show a wide variety of uses for the present invention for consumer and/or commercial use.
