Description

[Detailed description of the invention] (a) Technical field to which the invention pertains The present invention relates to gateball shoes, which are used as a substitute for the gateball game popular in the Silver Age.

(b) Description of the Prior Art Various types of gateball shoes have been devised in the past, but no perfect shoes have yet been found and they have many defects.

For example, one example is that the contact surface between the unstepped part of the sole and the toe has a recess that is substantially a concave spherical surface, and the contact surface at the rear end of the heel of the sole is rearwardly upward. A gateball ball game shoe is presented that has a substantially sloped direction. However, in these shoes, the concave part provided in the adhesive surface between the unstepped part of the sole and the toe essentially constitutes a concave spherical surface, so it is difficult to cover it with almost no dust. If the gateball ball is to be used for a game, it will be held accordingly, but in reality, it is used for practice and competition at an outdoor practice field or stadium, even in the wetlands after rain, so there is no dust or dirt. Even if a small foreign object such as sand or dirt adheres to the ball, the holding force due to the full-surface contact between the concave spherical surface and the spherical surface of the gateball ball will essentially be lost, and the ball will become unstable as it floats on the concave spherical surface. Even if these gateball shoes are used, they have the drawback that the game cannot be played safely and effectively.

(C) Purpose of the invention The present invention provides a gateball shoes having a sole configured to securely hold a gateball ball and stabilize the feet of a user in this state. The purpose is to

(d) Structure of the invention The present invention is a gate ball shoe in which a sole 2 is fixed to the lower part of a shoe cover 1, and a hole 3 for holding a ball is provided in the inner part of the treading part of the sole 2, which opens toward the ground surface. The inner diameter of the opening inner edge 4 of this ball holding hole 3 is sized to be in close contact with the spherical surface of the gateball ball 5,
The inner surface of the ball holding hole 3 is formed to have an inner surface shape that does not come into contact with the spherical surface of the ball 5 present in the ball holding hole 3, so that even if small foreign matter adheres to the spherical surface of the ball 5 for gateball, Even if there is a small amount of dust or the like adhering to the ball holding hole 3, the spherical surface of the ball 5 present in the ball holding hole 3 will come into contact with the inner wall or bottom surface of the ball holding hole 3. It is characterized in that it is configured to come into close contact only with the inner edge 4 of the opening of the use hole 3. The bottom surface of the sole 2 is usually engraved with a sole design, but there is a ball holding hole 3 on this bottom surface.
When forming the ball holding hole 3, the ball holding hole 3 may be simply formed, or a ring-shaped auxiliary bank 6 surrounding the opening edge of the ball holding hole 3 may be formed.

(E) Description of Embodiments FIG. 1 shows a first embodiment of the present invention, and is a bottom view of a gate ball shoe, and FIG. 2 is a sectional view taken along the line A--A in FIG. 1.

The gateball shoes of this embodiment are constructed by adhering a sole 2 to the lower part of a shoe cover 1, and providing a hole 3 for holding a ball that opens toward the ground surface on the inner side of the treading part of the sole 2. be. The ball holding hole 3 is formed into a cylindrical shape, a truncated conical shape, a spherical shape, or the like. The inner dimension of the opening inner edge 4 of the ball holding hole 3 is defined to be at least smaller than the diameter of the ball 5 for gateball. Taking into consideration the diameter of the ball 5 and the shape and size of the sole 2, the inner dimension of the ball holding hole 3 is usually preferably formed to be approximately 1/3 to 1/2 times the diameter of the ball 5. Further, the ball holding hole 3 is formed with a draft angle to facilitate the formation of the sole 2 and to prevent dust and foreign matter from adhering to it. Furthermore, when the ball 5 for gateball and the inner edge 4 of the opening of the ball holding hole 3 come into close contact with each other, the bottom surface of the ball holding hole 3 is set at a depth that does not contact the spherical surface of the ball 5 present in the ball holding hole 3. form. For example, if the diameter of the ball 5 for gateball is 7 cm and the inner dimension of the ball holding hole 3 is 3 cm, the depth of the ball holding hole 3 will be deeper than 4 mm.

The gateball shoe of this example is the sole 2 of the shoe.
The inner diameter of the opening inner edge 4 of the ball holding hole 3 provided in the ball holding hole 3 is formed to be smaller than the diameter of the ball 5, so that the inner surface of the ball holding hole 3 and the spherical surface of the ball 5 present in the ball holding hole 3 are formed to be smaller than the diameter of the ball 5. Since the ball is formed at a depth that prevents contact with the ball, especially when practicing or playing gateball outdoors, foreign matter such as dust or sand may get inside the sole 2 or its ball holding hole 3 or touch the ball. Even if foreign matter adheres to the surface of the ball 5, the ball 5 is in close contact only with the sharp inner edge 4 of the opening of the ball holding hole 3, so that any foreign matter attached to the spherical surface etc. should be centered around the inner edge 4 of the opening. The spherical surface of the ball 5 and the inner edge 4 of the opening of the ball holding hole 3 are in direct contact with each other, and the ball 5 is reliably held in the ball holding hole 3.

In addition, since the ball 5 is in close contact with the entire circumference of the inner edge 4 of the opening of the ball holding hole 3, if the ball holding hole 3 is pressed against the ball 5 and the air etc. inside the ball holding hole 3 is pushed out. The ball holding hole 3 functions as a suction cup for the ball 5, and can hold the ball 5 reliably.

FIG. 3 is a bottom view of a gate ball shoe showing a second embodiment of the present invention. Ball holding hole 3 is the first
Similar to the embodiment, the inner part of the treading part of the sole 2 is formed to open toward the ground surface side, and the difference from the embodiment is that the ball holding hole 3
The opening shape is formed in a shape other than a circle, particularly a polygon, and can be formed in various shapes such as a prismatic shape or a truncated pyramid shape, and FIG. 3 shows a triangular prism shape. The rest of the structure is similar to that of the first embodiment, and the same reference numerals refer to the same parts.

According to this embodiment, since the shape of the ball holding hole 3 provided in the sole 2 is formed into a prismatic shape or the like, the spherical surface of the ball 5 and the inner edge 4 of the opening of the ball holding hole 3 are connected to each other. is engaged only at the center of each side of the polygon, and each vertex of the polygon does not come into close contact with the spherical surface, so air in the ball holding hole 3 and By pushing out dust and the like, the ball 5 is held more securely by the ball holding hole 3.

(F) Effects of the present invention In this invention, the ball holding hole that opens on the ground side of the sole of the gateball shoes is formed so that only the inner edge of the opening is in close contact with the ball. The contact area between the spherical surface and the inner edge of the opening of the ball holding hole is small, and the contact pressure between them is high, which increases the force of gripping the ball, making it difficult for the user to hold the ball securely. This ensures that your feet are stable and you can enjoy playing gateball with peace of mind and without any anxiety.
