DETAILED DESCRIPTION OF THE INVENTION

[0014] [First form] Fig. 1 is a diagram illustrating a vertically oscillating blade propulsion human-powered boat according to a first embodiment of the present invention. Fig. 3 is a diagram illustrating the vertically oscillating blade propulsion human-powered boat according to the first embodiment of the present invention and the movements of the rider.

[0015] The first form of vertically oscillating blade propulsion human-powered boat 100 comprises a buoyant body 6 placed on the water surface, a footboard 1 placed above the buoyant body and on which the rider stands, a propulsion blade 2 connected to an axis member 3 extending from the footboard and placed underwater, an auxiliary member 5 that assists the footboard in moving up and down, and a handle 4 that the rider grasps.When the rider uses his or her weight to step down on the footboard, the footboard 1 moves downward, the propulsion blade 2 sinks, and a forward propulsion force is generated; and when the rider removes his or her weight from the footboard 1, the footboard moves upward with the assistance of the auxiliary member 5, generating a forward propulsion force at this time as well.

[0016] In addition, when the rider presses down on the footboard 1 using his / her weight, the buoyant body 6 placed on the water surface moves back and forth, causing the buoyant body to sink downward, thereby reducing the resistance of the water that is generated.

[0017] In addition, the rider can hold the handlebars 4 and tilt the propulsion wings inward together with the footboards 1 to change direction.

[0018] The buoyant bodies 6 are arranged in front of and behind the footboards, and comprise a first frame formed in an axial shape, with one end rotatably connected to the buoyant body 6 arranged in front of the footboards and the other end rotatably connected to the footboards 1, and a second frame formed in an axial shape, with one end rotatably connected to the buoyant body 6 arranged behind the footboards and the other end rotatably connected to the footboards 1. The auxiliary member 5 is connected to the first and second frames and is a biasing member that biases one end of the first frame and the second frame in a direction toward each other. When the rider uses their weight to step down on the footboards, the propulsion wing sinks, generating a forward propulsive force and moving one end of the first frame and the second frame away from each other. When the rider removes their weight from the footboards 1, the biasing member moves one end of the first frame and the second frame in a direction toward each other.

[0019] The fixing device 18 can prevent the first frame and the second frame from moving away from each other, for example, thereby fixing the step board from moving up and down when boarding the boat or stopping on the water.

[0020] FIG. 2 is a diagram illustrating a propulsion blade of a vertically oscillating blade propulsion manpowered boat according to an embodiment of the present invention.

[0021] The propulsion blades 2 are made of flexible material at both wing tips to reduce turbulence at the wing tips that occurs during up and down movement, and the range of swing is adjustable to optimize the angle of elevation of the propulsion blades to respond to changes in the water flow speed from the front while moving.

[0022] In the mechanism for adjusting the swing range of the elevation angle shown in Figure 2, the swing angle of the propeller wing upper protrusion 17 is adjusted by moving the swing angle adjustment piece 11 up and down by operating a foot-operated ratchet lever 9 or a rotary handle grip pull wire type 10.

[0023] In addition, the propulsion wing 2 has a wing cross section that is the same as a symmetrical wing or has a similar shape, and as the propulsion wing moves up and down, the angle of elevation relative to the water flow causes a propulsive force to be generated by lift on the upper surface when moving downward, and on the lower surface when moving upward.

[0024] In addition, by selecting the propulsion wing 2 according to one's physical strength and preference, it is possible to select the speed, long duration, long distance running, etc., and it is easy to stop, rest, and then start again.

[0025] Furthermore, the propulsion fins 2 allocate most of the lift generated to forward propulsion, but when the body weight is applied and the fins step down, an upward force is also generated, so that even though a downward force is applied, the boat is in a semi-propulsion state, and when moving upward, the weight is removed, so the water resistance experienced by the buoyancy body can be reduced on both sides of the vertical movement, and a vertically oscillating fin propulsion human-powered boat can be provided that is small, lightweight, and easy to disassemble and assemble for transportation and storage.

[0026] [Second form] Fig. 4 is a diagram illustrating a vertically oscillating blade propulsion manpower boat according to a second embodiment of the present invention. Fig. 5 is a diagram illustrating the vertically oscillating blade propulsion manpower boat according to a second embodiment of the present invention and the movements of the rider.

[0027] In the second embodiment, the vertically oscillating blade propulsion manpowered boat 200, the auxiliary members 5 are a plurality of elastic frames that are elastically deformable and whose base ends are connected to the treads 1 and whose tip ends are connected to the buoyancy bodies 12. The multiple elastic frames that are auxiliary members 5 each extend radially from the tread 1 when viewed from above, and when the rider uses their weight to step down on the tread 1, the tread 1 moves downward, elastically deforming the elastic frame, and the restoring force of the elastic frame after elastic deformation can be used as a force to move the tread 1 upward.

[0028] In addition, by arranging a plurality of small buoyant bodies 12 and increasing or decreasing the number, the buoyancy can be adjusted according to the rider's weight.

[0029] In addition, when the rider steps down on the footboard 1 using their body weight, the buoyant bodies 12 placed on the water surface move radially, and the buoyant bodies sink downward, reducing the water resistance that occurs.

[0030] The small buoyant body 12 has a convex disc-shaped underside, and can be manufactured in a variety of ways, such as by plastic molding or by air expansion.

Fig. 7 is a diagram illustrating the vertically oscillating blade propulsion human-powered boat according to the third embodiment of the present invention and the movements of the rider.

[0032] In the third form, a vertically oscillating wing propulsion human-powered boat 300, narrow buoyant bodies 13 are arranged on the left and right sides of the footboard 1, and the auxiliary members 5 are formed of elastic members extending from the left and right buoyant bodies to the footboard 1, respectively.

[0033] The narrow buoyant bodies 13 are displacement type, arranged on the left and right sides of the tread 1, and connected to each other by cross beams 14, and are easy to sink with a downward force, and then, together with the force of the auxiliary member 5, the reaction of the buoyancy can move the tread 1 upward.

Fig. 9 is a diagram illustrating the vertically oscillating blade propulsion manpower boat according to the fourth embodiment of the present invention and the movements of the rider.
