DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to protective equipment for baseball, and more particularly, to a self-ball hit protector for protecting a leg when hit.

[0002]

2. Description of the Related Art In a baseball game, a batter swings a bat so that a ball hits the lower surface of the bat and the ball hits the batter's foot. This self-hit ball
For example, as shown in FIG. 6, the hit ball angle at that hit point,
Each factor such as the bat's impact area and the rotation of the ball overlaps, and the batter pushes forward directly to each part of the stepping foot (right foot for left batter, left foot for right batter), or bouncing to the ground or home base By hitting, the collision site is mainly as shown in the figure,
It is extremely likely that it is a part such as the calf, ankle, instep or thumb.

[0003] When the ball hits the foot directly with the ball,
If the ball is a soft ball, it only needs to be hitting, but if a hard ball is used, the impact due to the hit is extremely large.
Since the ball is hit by receiving a fastball at a pitching speed of 130 to 150 km / hour, the impulse of the ball at the time of hitting is extremely large. When the hitting place is bad, not only the hitting degree but also severe bruising and It can easily lead to serious accidents such as muscular rupture and damage, and fractures.

The most effective countermeasure is to mount a protector. At present, some protectors for protecting the leg have been proposed. Has been prototyped, but was not actually adopted for the following reasons.

[0005]

That is, in the conventional protector for self-hitting ball, the portion for the shin of the foot is formed of a hard resin having a substantially semicircular cross section. Attach it to the shank so that it covers from the front, and then tighten the opening of the back with a fastener such as Velcro (Trademark). Also, cover the part for the upper part from above the spike. It is necessary to tighten the opening at the lower surface with a fastener similar to the above.

[0006] However, in an actual game, the time of the offense and defense change is a very busy time for a player who comes to his turn at bat immediately after returning to his own bench,
It is difficult for the athlete to wear a protector for self-hitting ball, fasten fasteners, and take extra time such as confirming the wearing. Many athletes are standing at bat without wearing this.

An object of the present invention is to solve the above-mentioned problems, and an object thereof is to provide a self-ball striking protector which is lightweight and can be attached and detached with one touch.

[0008]

In order to achieve the above object, a self-ball striking protector of the present invention is formed of a resin molded body, is formed into a shape of a human foot from below the knee to an ankle, and has a rear portion in a vertical direction. And a piece of resin molded body, which is formed in the outer shape of the upper part of the spike shoe, and integrally provided with locking pieces at both ends of the lower edge for locking both sides of the arch of the spike shoe. It consists of a backrest piece and a bendable connecting plate that connects the two pieces.When the sunshine piece is mounted, the rear part is elastically expanded and fitted to the foot. Cover the outer periphery of the foot, fit the upper part while elastically expanding the lower part when mounting the upper part, and the locking pieces are locked on both sides of the arch when the mounting is completed, and fixed at the mounting position. That It is an butterfly.

According to the present invention, the undercarriage which is easily damaged by the hit ball can be protected, and it can be lightweight and detached with one touch.

[0010] Preferably, the shining piece and the instep piece are each formed from a fiber reinforced resin, and a cushion material is internally applied to the inside thereof.
As a result, the effect of protecting the shin and instep can be increased.

[0011] Preferably, the connecting plate is made of an elastic material formed in a shape deflected to a curved surface corresponding to an angle between the shin and the instep in the standing position. By maintaining the shape between the upper back pieces in the same posture as the foot shape, the operability at the time of attachment / detachment can be improved.

[0012]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Figure 1
FIG. 4 shows a self-hit ball protector according to the present invention.

The self-hit ball protector 10 in FIG. 1 is designed for a left foot, which is a foot that a right batter steps forward, and as shown in FIGS. 1 (a) and 1 (b), Upper back piece 14 and both pieces 12, 14
It is composed of three members of a connecting plate 16 which is connected between them, and both ends of the connecting plate 16
2 and the upper back piece 14 via a rivet 18 or an adhesive, etc., so as to be integrated into a foot shape from below the knee to the upper.

As shown in section in FIG. 3, a thin and light FRP outer shell 22 having a colored gel coat layer 20 coated on the surface thereof, and an inner shell of the outer shell 22 are provided on the inner surface of the outer shell 22. Cushion material 2 such as urethane foam resin attached
4, the front part of which is formed to have a foot-shaped cross-sectional shape from the ankle to the lower part of the knee, and the rear part is vertically separated via the slit 26 to maintain the foot shape.

At the time of mounting, the rear slit 26 is opened left and right, the outer shell 22 is elastically expanded and fitted to the foot, and after the fitting, the elastic body automatically returns to the original cross section. It fits and surrounds the uniform around the foot via the cushion member 24.

[0016] With this, it is possible to mount the apparatus without requiring any fastening means, and it is possible to maintain the mounted state without falling off following the movement. Also,
When the sunshine piece 12 is to be taken off, if the front upper edge is pulled forward, the rear slit 26 automatically expands and can be easily extracted.

As shown in FIGS. 1 and 2, an ankle protecting piece 28 for protecting the medial ankle of the left foot is integrally provided on one side of the lower part of the shining piece 12.

In addition, since the portion of the ankle is bone immediately below the skin and is greatly damaged at the time of hitting, it is formed to be slightly bulged outward as shown in FIG. I have.

The back piece 14 is also a sun piece 12
An FRP shell 22 coated with a surface gel coat in the same manner as
The spike shoe 30 is formed of an arcuate curved surface that follows the outer shape of the upper part of the spike shoe 30, and has spikes on both lower edges thereof. A locking piece 32 that resiliently engages both sides of the arch at the lower portion of the shoe 30 is integrally formed.

On the front edge of one side of the upper back piece 14,
The toe protection piece 34 is integrally formed to extend and protects the toe portion.

If the lower edge of the above-mentioned instep piece 14 is also fitted to the outer periphery of the instep of the spike shoes 30, the elastic piece returns to the cross-sectional shape of the spike shoes 30 in a state in which the locking pieces 32 are engaged with the side edges of the arch. Then, it fits around the spike shoes 30 via the cushion material 24 and surrounds them.

The connecting plate 16 is made of a leaf spring or an elastic material similar thereto, and is formed in a shape deviated in advance into a curved surface corresponding to the angle between the shin and the upper in the standing position, and is not used. However, as shown in FIG. 1 (b), while maintaining the shape between the shin patch piece 12 and the instep patch 14 in the same posture as the foot shape, as shown in the imaginary line, even in the bent state, The spring constant is set so that the user does not feel a large spring resistance.

The reinforcing fibers constituting the FRP outer shell 22 are, for example, FRP cloths used for surgical casts and the like, which are recommended materials because of their strength, thinness and light weight. Examples of the matrix resin include commonly used epoxies and unsaturated polyester resins.

In the above embodiment, the sunshine piece 1
Both the back piece 2 and the upper back piece 14 are intended to have a mounting force on the shiny part or the spike shoes by the elastic force of the resin.
One or a plurality of strips that return elastically, such as leaf springs, may be formed in advance on the inner surfaces of the second and upper back pieces together with the resin.

The gel coat layer 20 on the surface is formed by dispersing and mixing a colorant in a resin paint compatible with the above matrix resin, and can be colored in any color. Marks such as the name of the provider can be printed.

Further, if the cushion material 24 is too thick, it becomes heavy and difficult to use. Therefore, the cushion material 24 only needs to be set to such a thickness that it fits lightly on the outer periphery of the foot in the mounted state. Even if there is, it can be sufficiently covered by the shock absorbing force of the outer shell 20.

In the above embodiment, the cushion member 22 is particularly applied to the upper back piece 14. However, since the spike shoes 30 can be sufficiently used as the cushion member, a configuration may be adopted in which the spike shoes 30 are not provided.

FIG. 5 shows a hitting form of a batter equipped with the self-ball hitting protector 10 having the above configuration.

When the protector 10 is worn, it is only necessary to fit the shining piece 12 into the shin, and then attach the instep piece 14 to the spike, whereby the mounting is completed and quick wearing is possible.

Then, at the hitting position where the batter swung the bat, as described above, the ball was directly hit, or the cushion ball was hit according to the angle of the batter.
Even if it hits the ankle, instep, thumb, etc. directly, it hits each part covered with the hit ball protector 10, but it hits the ball, but there is almost no pain or injury, and the damage accident by the hit ball Can be prevented.

Further, when the batter hits, he or she runs out while the protector 10 is worn. However, the protector 10 is lightweight and the flexibility of the bending part such as the ankle is sufficient, so that the influence on the running speed is also reduced. Less. Then, after the start, the protector 10 may be removed, or the mounted state may be maintained, as in the case of the detachable helmet.

In the above embodiment, the protector 10 for the left batter is used. However, it is needless to say that the protector for the right batter can be manufactured in the same manner as the mirror.

[0033]

As is apparent from the above description, the self-hit ball protector according to the present invention can protect the underbody that is easily damaged by the self-hit ball,
Since it is a resin molded product, it is lightweight and does not affect running after impact.

Further, since it can be mounted by utilizing resin elasticity,
There is no need for fixing means such as Velcro, so it can be attached and detached with a single touch, and can be worn immediately and stand in the batter's box even during a busy time after the change of offense and defense.

Accordingly, there is no influence on the game by wearing the protector of the present invention, and by requiring all the players to wear it, the safety of the game can be further enhanced.
