<First Embodiment>
1 is a perspective view of the swimming practice tool 1, and FIG. 2 is a top view of the swimming practice tool 1 seen from the upper side in FIG. There are no restrictions on the material of the swimming practice tool 1, and known materials can be used as appropriate. For example, elastic plastic such as rubber/silicone, hard plastic, metal, etc. are particularly preferably used. The entire swimming practice tool 1 may be integrally formed by a method such as injection molding using a mold, or may be formed by combining a plurality of members using metal or the like. Of course, a plurality of types of materials may be used in combination.

The swimming practice tool 1 has a wing portion 2 and a finger fixing portion 3. The swimming practice tool 1 is used by fitting the user's finger by inserting the finger into the finger fixing part 3 having the central hole 3R (3AR, 3BR).

The blade portion 2 is perpendicular to the tangent line of the finger fixing portion 3 at the root portion of the blade portion 2 (that is, the circumferential direction of the finger fixing portion 3) and the central axis direction of the center hole portion 3R (that is, the finger penetrating direction). And is arranged so as to project along the length direction of the finger and perpendicularly from the circumferential direction of the finger when the finger penetrates the center hole 3R.

The blade portion 2 has blade members 2A and 2B which are two plate-shaped members. The blades 2A and 2B have substantially the same shape and have a drop shape in which one side is thin, the other side is widened, and the other side is chamfered. Hereinafter, one end of each of the blade members 2A and 2B on one side having a narrow tip is referred to as a thin end 2D, and an end of the other widened side is referred to as a wide end 2U. The blade members 2A and 2B are arranged substantially parallel to each other, and a parallel gap 2G having substantially the same width is formed.

The finger fixing part 3 is composed of two rings 3A and 3B. The rings 3A and 3B have a shape in which a part of a circular ring or an elliptical ring is cut out, and the ring 3A is connected to the narrow end portion 2D of the blade members 2A and 2B, while the ring 3B is connected to the blade member 2A. , 2B from the center to the wide end 2U. That is, in the rings 3A and 3B, the blade members 2A and 2B are arranged at the tips of the cutout portions, and the ring gap 3G is formed in the cutout portions corresponding to the parallel gap 2G.

The rings 3A and 3B are connected to each other on the opposite side (at a position separated by 180°) from the cutout portion to form a ring connecting portion 3C. In the ring connecting portion 3C, the rings 3A and 3B are arranged in a state of being inclined by about 40 to 80° (more preferably 50 to 75°).

The wide end portion 2U of each of the blade members 2A and 2B projects from the finger fixing portion 3 by about 1/3 to 1/4 of the entire length (as a length). Further, since the rings 3A and 3B are connected to the two blade members 2A and 2B arranged with the parallel gap 2G, the ring gap (including the elliptical ring) is the same as the parallel gap 2G. 3G is formed, and the rings 3A and 3B can be deformed to absorb the difference in finger size.

In the swimming practice tool 1, all the so-called corners (recesses and recesses) that connect straight lines are chamfered, and all straight lines are smoothly connected via curved lines. This enhances safety and suppresses the generation of unnecessary turbulence.

The swimming practice tool 1 is fixed to the base of the finger by passing the finger through the rings 3A and 3B of the finger fixing portion 3. As shown in FIG. 3, by arranging the blade portions 2 between the fingers in a parallel direction, it is possible to form a web between the fingers. At this time, the two blade members 2A and 2B are brought into contact with and fitted to the adjacent fingers, and at the same time, the flesh and skin of the fingers can be bitten into the parallel gap 2G to firmly fix the blade unit 2.

Thereby, the area of the hand is increased, the resistance of water is increased, and the training for strengthening the muscle force applied to the muscles of the palm, wrist, and arm can be effectively performed. It should be noted that the number of swimming practice tools 1 to be used is changed by changing the area of the feathers 2A and 2B, the spread angle of the narrow end 2D, the length of the feathers 2A and 2B (the length in the direction parallel to the finger), and the like. By adjusting, the resistance of water to be increased can be adjusted appropriately.

Here, in swimming competitions, the player moves forward mainly by scratching the water with his hands. At this time, it is preferable that the portion that directly scratches the water receives more resistance to generate the forward force, but in other portions, the resistance should be made as small as possible so as not to hinder the forward force. desirable. The finger is also the same, and in order to secure the forward force at the level of 0.1 seconds, it is desirable to avoid the resistance force in the useless direction and generate only the forward force.

Therefore, in the swimming practice equipment 1 of the present invention, as shown in FIG. 4, the wings 2 are arranged so as to stand substantially vertically from the backs of the fingers. As a result, each finger has a dorsal fin, and it is possible to make it easier for the user to recognize the resistance that the finger receives from water, and it is possible to adjust the resistance that each finger receives from water. Although FIG. 4 shows the case where the narrow end portion 2D is used as the base side of the finger, the wide end portion 2U can be used as the base side of the finger. The magnitude of the resistance can be adjusted by arranging the direction of the narrow end portion 2D (the base side or the tip side of the finger).

By the way, as shown in FIG. 5 showing a state in which the wide end portion 2U is fitted to the user's finger with the base side of the finger, the human hand can be determined from the positional relationship of the MP joint (indicated as MP in the figure) at the base of the finger. , The straight part is long on the back side of the finger, which is the back side of the hand, and the straight part is short, on the ventral side of the finger, which is the palm side. Since the finger fixing portion 3 has a triangular shape as a whole when viewed from the side surface (the angle at which the surface of the blade portion 2 is viewed from the front), the finger fixing portion 3 can be firmly fitted to the base portion of the finger.

Further, at the wide end portion 2U where the blade portion 2 projects from the finger fixing portion 3, the blade portion 2 is formed so as to be separated from the finger (that is, to enter inside from the extension of the straight line connecting the rings 3A and 3B). Therefore, regardless of the position of the MP joint, the blade portion 2 does not come into contact with the MP joint and the blade portion 2 does not hinder the movement of the MP joint.
