Abstract

PURPOSE: To perform simple propulsion of a boat and a marine vehicle with a man power by a method wherein a hand row handle part is horizontally reciprocated and a paddle plate is oscillated in a given angle range through the medium of a resilient body to generate a propulsion force. CONSTITUTION: One side of a paddle plate 1 is fixed to a support member 2 clamping a resilient body 3 therebetween. When the handle part 5 of a horizontal member 4 is led to effect horizontal reciprocating movement, the support member 2 effects horizontal reciprocating movement in water around a fulcrum 6. Since contrary to the above, the tip part of the paddle plate 1 follows in a delay at a given angle with a radial direction, the support member 2 pushes water in an intermediate direction between a movement direction and the rear of a boat and the boat is pushed by means of a reaction force thereto. This constitution eliminates a need for a heavy and long Japanese scull and an oar and performs operation without needing a skill and training. By horizontally fixing the paddle plate 1, reciprocating movement with legs is also practicable.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The invention of wood is similar to the sword and paddle of a Japanese ship that propels a ship by human power. It sends water backward by reciprocating rotation in water and mounts it on the ship by reaction. The present invention relates to a device for propelling the object forward.

[0002]

2. Description of the Related Art Conventionally, turrets and paddles have been used in Japan since ancient times in order to manually propel fishing boats, ferry boats, horse-riding boats and the like. These propulsion tools had the advantage of being able to propel a relatively large ship by one person, but they were large and heavy,
Manipulating these requires a strong physique and special skills, and it took a long time to train them so that no one could operate them immediately. The turret and paddle enter the water surface at an angle, but one point thereof moves in a Z shape as shown in FIG. 11, and at the same time, its rear surface is directed to push water backward. In the past, toy fish and other fish used to swing the tail fin to the left and right to move forward, but pushing the water sideways without bending it consumed a lot of energy, and only part of the applied force was used as propulsive force. The efficiency was low and it was not practical as a propulsive force for ships, surfboards, starter-like vehicles, etc.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device capable of advancing a ship or a water vehicle by human power by using a water scraping plate instead of a stake, without anyone needing to be trained. To aim.

[0004]

According to the present invention, a vertical support village is attached to one end of a horizontal member, one side of a plate-shaped water scraping plate is attached to the support member, and a fulcrum is provided at an intermediate portion of the horizontal member. With the other end as a rowing handle part, it is configured to be capable of horizontally reciprocating rotation, and the handle is a handle from the water scraping plate so that the water scraping plate can take an angle with respect to the direction of the radial line connecting the fulcrum and the supporting member. It is a propulsion device for a water vehicle in which an elastic body or an elastic device is incorporated between the parts, including a case where the water scraping plate itself is an elastic body, and the water scraping plate is attached in water. In addition, it also includes a propulsion device in which the above-mentioned device is rotated about 90 degrees around a horizontal member and the water scraping plate and the supporting member are attached to the water outside the outboard.

[0005]

As shown in FIG. 1, the principle of the water scraping board propelling a ship is to horizontally reciprocate the handle part in the traveling direction,
The lateral movement of the support member relative to water,
It is necessary for the tip of the water scraping plate attached to the support member to follow the movement of the support member at an angle such that it lags behind. To receive the reaction force of.

When the above-mentioned device is rotated about 90 degrees around a horizontal member and the support member for the water scraping plate is attached outside the port side or outside the stern, the handle part is vertically reciprocated inside the ship. So you can use your legs.
Also, when the support member of the water scraping plate protruding into the water moves reciprocally relative to the water due to the vibration of the ship during stoppage, the water scraping plate automatically scratches the water and propels the ship due to the above reasons. To do. In other words, some propulsive force can be obtained just by drifting in the waves.

【Example】

A. Example of elastic device 1. In FIG. 1, one side of the water scraping plate 1 is fixed to the support member 2 with the elastic body 3 interposed therebetween. When the handle portion 5 at the front end of the horizontal member 4 is horizontally reciprocally rotated, the support member 2 is horizontally reciprocated in water about the fulcrum 6. On the other hand, since the tip of the water scraping plate 1 follows the radial direction with an angle (hereinafter referred to as a declination angle) with the radial direction, the support member 2 pushes the water in the intermediate direction between the moving direction and the rear of the ship. , Propels the ship by its reaction force. 2. FIG. 2 shows an elastic body interposed between the water-draining plate 1 and the support member 2 in which a cylindrical rubber 3a is inserted into a cylindrical hole of the water-draining plate 1 by inserting a vertical groove or an adhesive, and the supporting member is provided at the center thereof. 2 A structure in which the lower end portion is inserted into the flat portion 7 may be used. 3. FIG. 3 shows an elastic body 3 for damping the deflection angle of the water scraping plate 1, in which a supporting member 2 is passed through a supporting cylinder 2a, an upper end of which is horizontally bent and a receiving plate 8 is fixed at a right angle, and coil springs 10 are provided at both ends. Parallel member 1 which is attached and parallel to the horizontal member 4
The pressing plate 9 is fixed at a right angle to one end of the coil spring 1, and the other end of the coil spring 10 is received. In this structure, by rotating the screw 12 at the other end of the parallel member 11, the length of the coil spring 10 can be adjusted to adjust the braking force. The elastic body 3 may be further incorporated in order to increase the deflection angle of the water scraping plate 1. 4. In FIG. 4, the upper end of the support member 2 is bent to the ship side and the horizontal portion 15 is formed.
And a Y-shaped pressing portion 8 fixed in parallel with the horizontal member 4
Put the coil spring 16 between each piece of the Y-shaped pressing part 8 and the horizontal part 15, and adjust the length with the adjusting bolt 17 to adjust the braking force. is there. 5. In FIG. 5, the water scraping plate 1 is made of a resilient material in the shape of a fin of a fish in a horizontal cross section, and the front part near the supporting member 2 is relatively thick and rigid, and is gradually thinned and softened toward the rear. It changes its shape due to the resistance of water and naturally deviates from the radial line to generate propulsive force. 6. FIG. 6 shows the relative movement of the water scraper 1 with respect to water.
When the water is pushed diagonally rearward in the horizontal direction, some of the water is pushed also in the vertical direction to cause a loss of propulsion energy. To prevent the loss, horizontal straightening vanes 18 are provided above and below the water scraping plate 1. It is fixed.

B. Example of mounting form. FIG. 7 shows a case where two sloping boards 1 are mounted on the stern. When one paddle board 1 is attached to the stern for rowing, the paddle board 1 pushes water diagonally rearward, so that the stern moves diagonally forward in reaction to it. In other words, the stern always swings to the left and right during travel, which makes the ride uncomfortable. To prevent this, if the two stern plates 1 are attached to the stern and are reciprocally moved symmetrically, the orthogonal component of the progress is canceled out.
The ship can go straight without swinging the stern from side to side. In order for one person to move the two water scraping plates 1 symmetrically, the horizontal members 4 and 4a of the two trees are arranged in parallel with each other in the traveling direction, and from one fulcrum 6 a certain distance forward and the other fulcrum 6a. By connecting the rear fixed distance with the connecting rod 21, the symmetrical motion is approximately established and can be easily implemented. However, due to its low force transmission efficiency and heavy weight, it is available only in the small angle range. ． FIG. 8 shows a structure of the water scraping plate 1 when the boat is moved forward and backward. The support member 2 is structured to be rotatable with respect to the horizontal member 4 by the handle bar 22, the handle bar 22 is fixed at a position rotated 180 degrees from the forward position, and the handle portion 5 is reciprocated to move the ship. Can be moved backwards. ． FIG. 9 shows a device capable of moving the stern in any direction. In this case, the upper part of the supporting member 2 of the water scraping plate 1 is supported by the vertical receiving portion 23, the lower part of the supporting member 2 is bent to provide the horizontal member 4a, and the upper end of the supporting member 2 is provided with 3
The handle ring 24 is fixed so that it can be easily held at any position of 60 degrees. If the handle wheel 24 is turned in the direction in which the stern is to be moved to determine the position of the water scraping plate 1 and the handle wheel 24 is reciprocally rotated about that position, the stern moves in the desired direction. That is, the boat can be advanced in all directions depending on how to position the water scraping plate 1. ． FIG. 10 shows a case where the water scraping plate 1 is attached to the port side or below the water surface of the ship bottom. When the support member 2 is placed horizontally from the port side, the support member 2 is attached to the base plate 25 attached to the port side,
The support member 2 may be fixed as long as the elastic body 3 is interposed between the support member 2 and the water scraping plate 1 or the water scraping plate 1 is made of an elastic body. If the elastic body 3 is not interposed, the elastic body 3 is rotatably attached, and a braking portion by the elastic body is required in the port side.
In this device, the horizontal support member 2 moves relative to the water by the pitching and rolling of the ship, and the water scraping plate 1 moves forward by the recoil of pushing the water backward. In this case, the horizontal member 4 is the ship itself. When the support member 2 and the water scraping plate 1 are vertically projected downward from the ship bottom,
The relative motion of the support member 2 with respect to water occurs not only due to the pitching and rolling of the ship but also due to the swinging motion of the ship, and a large amount of energy is acquired from the shaking of the ship. A space 26 is provided for accommodating the support member 2 protruding horizontally from the port side and the water scraping plate 1. The space 26 has the same cross-sectional area as the support member 2 and the base plate 25 of the water scraping plate 1. If the base plate fixing bolt 27 is removed and the base plate 25 is retracted by the length of the support member 2, the storage is completed. When the water scraping plate 1 is projected downward from the bottom of the ship, a storage space is provided at the upper side, although not shown, and the support member 2 and the water scraping plate 1 can be stored therein together with the base plate. FIG. 11 shows the trajectory from the start of the support member 2 and the declination of the water scraping plate 1.
