2 ）。Next, an operation method and a rescue method of the rescue device A configured as described above will be described. As shown in FIG. 2, first, an operator (rescue person) B is located on one shore C on the near side of the river, and attaches the main body 1 to the river by the string connectors 1a and 1b.
Is floated on the front side, and the reels 4a and 4b are held by hand or fixed to the ground or the like by appropriate means, and the operation cords 3a and 3b are extended from the reels 4a and 4b to a sufficient length. Just pay out. Then, by adjusting the lengths of the operation strings 3a and 3b while the operation strings 3a and 3b are in tension, that is, by making the length of the operation strings 3a slightly shorter than the length of the operation strings 3b, a thick arrow is used. The fins 2 are inclined such that the opposite shore D side of the fin 2 is upstream and the front C side is downstream with respect to the indicated water flow. That is, a plurality of operating members 3a, with adjusting the length of the 3b, by a state of being tensioned operating member 3a, the 3b, fin the distance L 1 between the end 2a and the opposite bank D side of the water flow of the fin 2 2
As water is smaller than the rear end 2b and the distance L 2 between the opposite bank D side of the tip 2a of the water flow of the fin 2 is close to the opposite bank D side, the rear end 2b of the water flow of the fin 2 is far opposite bank D side The fin 2 is inclined so that the main body 1 is guided to the opposite shore D side by using the water flow received by the fin 2 (L 1 <L

れた。By maintaining the inclination of the fin 2, a propulsive force acts on the fin 2 toward the upstream side in the longitudinal direction of the fin by the force of the water flow. As a result, the main body 1
It moves from the position (a) to the position (b) and further to the position (c) so as to draw an arc as shown by a two-dot chain line. If the operation cord 3a is loosened at the position (c), the body 1 draws an arc from the position (c) to the position (b) and further to the position (a) by the force of the water flow. And move on. Note that, depending on the connection positional relationship of the operation cord 3a to the main body 1, when the main body 1 starts moving, the operation cord 3b is further extended to release the tension of the operation cord 3b. It has been confirmed by experiments by the present inventor that the state is maintained and the main body 1 is continuously moved.

The fin 2 inclined so that the front side C is on the downstream side,
As shown in FIG. 3, the operation string 3a receives the force F due to the water flow.
And to 3b are tense control cord 3a and 3b receives the moment of clockwise, the body 1 is moved in the direction of F 1. As described above, the operation strings 3a and 3b receive the clockwise moment due to the water flow of the fins 2 so that the main body 1
And the length of the operation cords 3a and 3b is adjusted.

That is, based on the position of (d), (e) maintains the inclination of the fin 2 and the length of the operation strings 3a and 3b, and (v) maintains the inclination of the fin 2 while maintaining the inclination of the operation strings 3a and 3b. If the length of the fin is longer,
When the lengths of the operation strings 3a and 3b are shortened while reversing the inclination of (a), (h) shows the movement position of the main body 1 when the operation strings 3a are loosened.

The rescuer can be provided with a life-saving device 5 such as a life jacket or a floating ring mounted on the main body 1 and rescued in a short time. If the buoyancy of the main body 1 is sufficiently large, the rescuer can be rescued by placing the rescued person on the main body 1 or holding the rescued person on the main body 1.

(The first fin 2 'is inclined such that' a is near the opposite shore and the rear end 2'b of the water flow of the first fin 2 'is farther to the opposite shore.)
The point that the main body 1 is moved toward the opposite shore D side by using the resistance of the water flow received by the first fin 2 ′ by tensioning the operation member 3 ′ is the same, but the vertical line OO and the The angle θ between the first fin 2 ′ and the first fin 2 ′ is a position where the angle θ is larger than 0 ° and smaller than 90 ° clockwise as viewed from the upper surface of the main body 1 (for example, θ is about 50 °), and the inclination of the second fin 2 ″ is Passes through the front end 2 "a of the water flow of the second fin 2" and the rear end 2 "b of the water flow of the second fin 2" with respect to a line parallel to the first fin 2 '. The difference is that it is inclined so as to be in a position rotated counterclockwise when viewed from above.
