[Technical field]

[0001] The present invention relates to an assist mechanism for a hydrofoil vehicle. [Background technology]

[0002] Conventional hydrofoil vehicles are designed solely for foil running and are comprised of only a main wing, a front wing and a structural frame.

[0003] In order for such hydrofoil vehicles to generate lift on the main wings and fly, it is essential that they have an initial forward speed that allows water to flow from the front onto the vertically oscillating wings. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide an assist mechanism capable of obtaining an initial forward velocity for wing propulsion on a hydrofoil vehicle. [Means for solving the problem]

[0012] The auxiliary mechanisms 100A to 100E are equipped with a hydrofoil that is placed underwater and a step section 4 that is placed above the hydrofoil and on which a person stands, and are attached to the hydrofoil vehicle 1 that moves in the forward direction when a person stands on the step section 4 and applies force in the upward or downward direction, causing the hydrofoil to move up and down, and which is equipped with a propulsion generating section (e.g., a horizontal propulsion fin 3, a rotating paddle board 8, etc.) that generates propulsive force in the forward direction when the person applies a downward force.

[0013] The propulsion generating section (e.g., a rotating paddle board 8, etc.) is positioned above the step section 4 and comprises an auxiliary step 7 that moves downward when a person stands on it, and a board shape connected to the auxiliary step 7 with a paddle surface, such that the force of the auxiliary step 7 moving downward causes the paddle surface to move backward from the direction of travel in the water (e.g., a rotating paddle board 8, etc.).

[0014] The rotating blade (eg, rotating paddle 8) may be moved backwards or the propulsion horizontal fin 3 may be moved from underwater to above water.

[0015] The auxiliary mechanisms 100A to 100E are provided in the vicinity of the step portion 4 and may include a buoyant body 2 that floats on water.

[0016] The propulsion generating section of the auxiliary mechanisms 100D and 100E comprises an auxiliary buoyant body 9 arranged below the step section 4, and a connecting member (e.g., an auxiliary pipe 11) whose upper end is rotatably connected to the step section and whose lower end is connected to the auxiliary buoyant body 9. When a person stands on the step section 4 and applies a downward force, the step section 4 falls forward, generating a propulsion force in the direction of travel.

[0017] The assist mechanism 100A shown in Figure 1 fixes a buoyant body 2 for supporting the weight to the frame of the hydrofoil vehicle 1 with an attachment hinge 5 and a lower fixing pin 6, and when starting off, the fixing pin 6 is removed to pop up the buoyant body 2 (see Figure 2), and the initial speed can be obtained by moving the propulsion up and down fin 3 in the same way as when the rider applies up and down force to the step 4 in wing running.

[0018] The buoyant body 2 of the assist mechanism 100A shown in FIG. 2 moves above the water surface during wing swimming in order to obtain buoyancy in a stationary state.

[0019] The buoyancy body 2 is made of foamed plastic or air-inflatable, and is made of an ultra-lightweight material that has high buoyancy even if it is fragile.

[0020] As shown in FIG. 3, when the hydrofoil vehicle 1 starts to run on its wings, the propulsion fins 3 of the auxiliary mechanism 100A move from underwater to above water, with the pivot fulcrum 12 as a fulcrum.

[0021] As shown in FIG. 4, the auxiliary mechanism 100B is disposed above the step portion 4 and comprises an auxiliary step 7 that moves downward when a person stands on it, and a rotor 8 that is connected to the auxiliary step 7 and formed in a plate shape with a paddle surface, and in the water, the paddle surface 8 moves backward from the direction of travel due to the force that moves the auxiliary step 7 downward.

[0022] 5, the assist mechanism according to claim 2, wherein the rotating blades 8 of the assist mechanism 100B move from underwater to above water while moving backward.

[0023] As shown in FIG. 6, the auxiliary mechanism 100C has multiple movable pulleys 15 provided on the auxiliary step 7, and one end of the rope wound around the pulleys is connected to the rotating blade 8, allowing the paddle surface to move a long distance backward from the forward direction underwater.

[0024] As shown in Figure 7, the auxiliary mechanism 100D has an auxiliary buoyancy body 9 below an auxiliary pipe 11 installed at the rear of the frame of the hydrofoil vehicle 1, and when the fixing pin 6 is removed from a position high above the water surface and a person stands on the step portion 4 and applies a downward force, the step portion 4 falls diagonally forward and an initial velocity is obtained.

[0025] The front auxiliary buoyancy body 10 has a shape that stabilizes the front wing 17 while sliding on the water surface in order to prevent the front wing 17 from plunging into the water when the boat starts moving forward.

[0026] An auxiliary mechanism 100E shown in FIGS. 8 and 9 is different from the auxiliary mechanism 100D shown in FIG.

[0027] In the auxiliary mechanism 100E shown in Figures 8 and 9, the auxiliary buoyancy body 9 below the auxiliary pipe 11 is composed of foamed plastic 13 and air-inflatable 14, making it easy to adjust the buoyancy, and the entire body tilts diagonally forward and downward on the upper fulcrum 12, while at the same time moving backward.
