Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spike fitting for baseball shoes.

[0002]

2. Description of the Related Art Conventionally, as a spike fitting of baseball shoes, a plate-shaped protruding piece provided on a toe ball, a toe ball and a toe is known (for example, Japanese Utility Model Registration No. 1).
3,015,023, see Japanese Utility Model Application Laid-Open No. 58-152104). These toe balls and the like are important sites for exhibiting motor functions. On the other hand, in baseball, unlike other sports, sufficient consideration is not given even though various actions are required.

That is, a spike fitting 100 shown in FIG.
When the protruding piece 101 below the toe ball is linear,
When you move your feet forward or sideways,
Corresponding to the direction in which the protruding piece 101 engages with the ground and the stepping-out direction, the protrusion does not engage with the ground, resulting in a decrease in motor function. In addition, the spike is likely to slide in the direction D along the protruding piece 101.
Therefore, the motor function is reduced.

[0004] Like a spike fitting 200 shown in FIG.
When the protruding piece 201 below the toe ball is curved in an arc shape, it is relatively easy to catch the ground both forward and sideways. However, since the protruding piece 201 is not sufficiently curved, the ground cannot be sufficiently grasped. Moreover, the spikes easily slide in the direction R along the curve of the protruding piece 201. Therefore, the motor function is reduced.

Accordingly, an object of the present invention is to provide a baseball shoe spike fitting capable of improving various athletic functions in baseball.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention is directed to a method of bending a plurality of portions of a metal substrate so that plate-shaped first, second and third projections are formed on the substrate. And the first, second and third projections are respectively
In a baseball shoe spike fitting disposed at positions corresponding to a toe ball, a toe ball, and a toe, the planar cross-sectional shape of the first protruding piece is generally formed in an inverted "H" shape. Features.

[0007] In the present invention, the first protruding piece provided near the ball of the toe has a substantially cross-sectional shape in a plan view, so that the first protruding piece is more soiled than a straight protruding piece. The working pressure increases. In addition, two sides forming the inverted "he" character work to engage the ground forward and to the side, respectively.
This creates resistance in these directions. In addition, since the first protruding piece is formed in an inverted "H" shape, this first protruding piece is formed.
The foot is unlikely to slide in the direction along the projecting piece, and the resistance is sufficiently exhibited.

In the present invention, the center angle of the inverted “H” -shaped projecting piece is generally preferably set to an angle smaller than 150 °, and more preferably in the range of 120 ° to 150 °. The angle is 135 °.

In the present invention, the inverted “H” shape and the “H” shape include not only the protruding piece's plane cross section being bent but also the direction of the protruding piece with respect to the front-back direction of the foot. Conceptually, in the present invention, it means that the central angle of each of the projecting pieces is directed to the center of the substrate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a right foot spike shoe for baseball as viewed from the back. In this figure, a first spike fitting 10 and a second spike fitting 20 are attached to a forefoot part and a rear foot part of a sole 30 of the spike shoe, respectively. In FIG.
The first spike fitting 10 includes first, second, third, fourth, fifth, and sixth projecting pieces 1, 2, 3, 4F, 4B, 5
F, 5B, and 6 are formed integrally with, for example, one substrate 11 made of metal. Each of the protruding pieces 1, 2, 3, 4F, 4
B, 5F, 5B, and 6 are formed by bending a plurality of portions of the metal substrate 11 substantially perpendicularly to the substrate 11.

FIG. 2 is a top view of the first spike fitting 10, showing the relationship with the skeleton of the foot. The first, second and third projecting pieces 1, 2, 3
Are arranged at positions corresponding to the toe ball M, the toe ball C and the toe F, respectively.

FIG. 3 is a bottom view of the spike fitting 10 for the left foot. As shown in this figure, a pair of fourth projecting pieces 4F,
4B are separately arranged in front and rear at a position between the first protrusion 3 and the third protrusion 3. The pair of fifth protrusions 5F and 5B are composed of a second protrusion 2 and a third protrusion 3.

In FIG. 3, each of the first and second projecting pieces 1 and 2 is formed in a substantially inverted "H" shape in plan sectional shape. On the other hand, the third protruding piece 3 is formed substantially in the shape of a letter "H". Here, the “he” character and the reverse “he” character mean that the central angles α1, α2, α3 of the respective protruding pieces 1, 2, 3 are respectively directed substantially toward the center of the first spike fitting 10. Means that The central angle refers to, for example, an angle α1 smaller than 180 ° among the angles formed by the two sides 1a and 1b of the first protruding piece 1. In the present embodiment, the central angles α1, α2, α3 of the three projecting pieces 1, 2, 3 are set to, for example, 135 °.

The central angles α1 to α3 are determined for the following reasons.
It is preferable to set the angle in the range of 120 ° to 150 °. FIG.
As shown in (a), as the central angles α1 to α3 decrease from 180 °, the road surface resistance gradually increases.
°, the increase in the resistance becomes slow, and at about 120 °, the increase in the resistance becomes asymptotic. On the other hand, as shown in FIG. 4B, as the center angles α1 to α3 become smaller than about 160 °, the weight of the protruding piece increases, but when it becomes smaller than 120 °, it suddenly becomes heavier. Therefore, in order to increase the road surface resistance without increasing the weight by a small amount, it is generally preferable to set the central angles α1 to α3 in the range of 120 ° to 150 °.

The first sides 1a, 2a of the first and second projecting pieces 1, 2 respectively engage with the ground when the foot is stepped forward. On the other hand, the second sides 1b and 2b of the first and second projecting pieces 1 and 2 engage with the ground when the foot is stepped on in the lateral direction. The two sides 3a of the third projection 3 are
When stepping forward, just before the foot leaves the ground,
Engage firmly with the ground. In addition, the fourth to the sixth
The projecting pieces 4F, 4B, 5F, 5B, 6 engage with the ground so as to assist the engaging force of the first to third projecting pieces 1, 2, 3 when stepping on the foot.

The fourth, fifth and sixth projections 4F, 4
B, 5F, 5B, and 6 each have a planar cross-sectional shape that is linear. The fourth protruding pieces 4F, 4B are arranged at positions inside the foot, and are inclined toward the inside obliquely rearward of the foot. On the other hand, the fifth protruding pieces 5F and 5B are arranged at positions outside the feet, and are inclined toward the outside diagonally rearward of the feet.

The pair of fourth projecting pieces 4F, 4B are arranged substantially parallel to each other and at an angle so as to intersect with each other. The two extension lines L4 and L4 extending in the direction intersect at a position outside and obliquely forward of the spike fitting 10. On the other hand, the pair of fifth protrusions 5
F, 5B are arranged substantially parallel to each other and at an angle so as to intersect with each other.
The two extended lines L5 and L5 extending in the longitudinal direction in the plane cross-sectional shape of B are arranged so as to intersect at a point O at a position inside and obliquely forward of the spike fitting 10.

Each of the projections 4F, 4B, 5F, 5B, 6
Are arranged so as to be useful for a ball catching operation, a pitching operation, a forward dash (stepping), a lateral stepping at the time of stealing, a forward propulsive force at the time of stealing, and the like, respectively.

For example, the fourth protruding pieces 4F and 4B are

On the other hand, at the time of batting, the foot rotates around the vicinity of the toe ball M (FIG. 2), but the above-mentioned projections 1, 2, 3, 4F, 4B, 5F, 5B, 6 Are arranged so as not to cause a large resistance during this rotation.
That is, the first, second and third projecting pieces 1, 2, 3
Are arranged along one circumference, so that the rotational resistance is reduced and batting can be performed smoothly. In addition, the fourth and fifth protrusions 4F, 4F
B, 5F, and 5B are also arranged in a direction along the circular motion centered on the toe ball M, and the rotational resistance is small.

As shown in FIG. 3, for example, two through holes 12 and 13 are formed in the center of the spike fitting 10. Thereby, the weight of the spike fitting 10 is reduced. The sixth protruding piece 6 is formed by bending the portion of the substrate 11 inside the through hole 13.

At the rear of the substrate 11 of the spike fitting 10, there is formed a cutout portion 14 which is cut out in the vicinity of the sixth projecting piece 6. As a result, a portion extending from the toe ball M to the toe ball C is formed in a substantially inverted concave shape. By notching the spike fitting 10 in this manner, the weight is reduced, and the bending rigidity of the spike fitting 10 is reduced, so that the torsion deformation of the spike fitting 10 is allowed. , And the sole 30 is easy to follow the foot, so that the motor function is improved.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art can easily envisage various changes and modifications within the obvious scope by referring to the present specification. Would. For example, the first, second, and third sides of the first, second, and third protruding pieces that form the letter “H” are each divided so as to form the letter “C”. 3
May be formed. Further, the substrate may be formed of a resin or a combination of a resin and a metal. Accordingly, such changes and modifications are to be construed as being within the scope of the invention as defined by the appended claims.

[0024]

As described above, according to the present invention,
Since the first protruding piece under the ball of the foot is formed in an inverted “H” shape, one side of the first protruding piece enhances dashing in the forward direction and running power after stealing. On the other hand, another side of the first protruding piece is laterally engaged with the ground, and effectively works for infield ball catching and pitching. Therefore, various motor functions in baseball are enhanced. Moreover, since the first protruding piece is bent in an inverted “H” shape, unlike the straight or arc-shaped protruding piece, a spike may slide along the protruding piece during each of the above operations. Absent.

Furthermore, the second protruding piece under the ball of the toe is also inverted.
If it is formed in the shape of "", it becomes more suitable for each of the above operations.
In addition, if the third protruding piece below the toe is also formed in the shape of “H”, the force for scratching the soil increases.
