Description

[Detailed description of the invention] This invention relates to a type of new swimming aid that is worn on the swimmer's hand during swimming. By wearing the equipment on the swimmer's hands in a specified manner while swimming, a much superior and stronger propulsion force can be obtained compared to swimming with bare hands. This is a new swimming aid that allows the user to swim freely and has been devised to provide an extremely simple structure at a low cost.

Next, the structure and operation of the swimming aid according to the present invention will be explained in detail with reference to the drawings of the embodiments. Fig. 1 shows an example of the most typical implementation structure of the swimming aid based on this invention. A flexible and elastic plate material such as rubber (natural or synthetic leather is acceptable) or synthetic resin is cut into a mushroom-shaped outline, and the main body 1 is cut into the base 1a of the main body 1. A teardrop-shaped through hole 2 is formed to form a loop part 3 that can fit around the swimmer's wrist, and a fan-shaped part 1 above the loop part 3 is provided.
b includes a circular lower finger hole 4 that can fit into the base of a swimmer's finger;
Five circular upper finger holes 5 that can fit the tip of a swimmer's finger are arranged radially at appropriate intervals.

In the case of this embodiment, the upper and lower finger holes 4 and 5 are provided with five holes each so that all the fingers of one hand, that is, the thumb, index finger, middle finger, ring finger, and little finger, can be inserted. One or two of the finger holes corresponding to the thumb, ring finger, and little finger may be omitted, and the fan-shaped portion 1b may be made smaller by that amount.

Since the swimming aid of the present invention has the above structure, in order to use it, first insert the swimmer's hand H into the through hole 2 from below the main body 1, and hook the loop part 3 onto the wrist part H□ to fix it. After that,
Thumb h1 of hand H penetrating upward, to index finger, middle finger h3,
The lower finger holes 4a correspond to the ring finger N1 and the little finger, respectively.
t 4b, 4c, 4d, and 4e from above and penetrate downward to firmly fix the lower finger hole 4 to the base of each finger.

Thereafter, the tips of the thumb h□, index finger, middle finger h3, ring finger N1, and little finger h5 are inserted from below into the corresponding upper finger holes 5at 5bt 5ct 5d, 5e and penetrated above the main body 1. By engaging and fixing the upper finger hole 5 with the tip of the finger, the aid can be attached to the swimmer's wrist H1.
It can be attached as shown in FIGS. 2 and 3 from the tip to the tip of each finger.

When swimming, if the swimmer wears aids on both hands using the procedure described above, unlike the conventional way of swimming with the five fingers of the swimmer's hands in close contact with each other while paddling the water, With the five fingers fully extended, the aid is held firmly at the tips and bases of each finger and at the wrist, and the base of the swimmer's hand and the entire fan-shaped group of the aid are used to propel the swimmer while paddling the water. Because of this, the surface area for catching water is extremely large, and it is possible to capture water accurately and obtain a powerful propulsive force.In addition, all of the water resistance acting on the assistive device is transferred from the wrist to the base and fingers. S is evenly distributed over the base and tip of the body and is transmitted to the swimmer's hands without strain, so there is no risk of putting too much strain on the swimmer's hands, and even swimmers with poor physical strength can go much faster than before. Swimmers can swim freely with speed, and physically strong swimmers can swim even faster.

As described above, although the swimming aid of the present invention has an extremely simple structure of simply punching a single rubber plate into a specific shape and shaping the bottom, it can be worn on the swimmer's hand. It is useful for increasing propulsive force during swimming, and it can be handled extremely safely, so combined with the fact that the manufacturing cost of the equipment is low, it has a remarkable practical effect.
