Description

  The present invention relates to a catcher chest protector used for baseball and softball.

In baseball and softball games, the catcher may hit the ball against his chest protector with a one-bound ball thrown by the pitcher and stop the ball, but the ball will spring back and allow progress. Sometimes.
For this reason, a material that does not repel the ball even when it collides with the chest protector is used.

  For example, a protector (for example, refer to Patent Document 1) in which EVA VN600 is used as a cushioning material for the chest part and the shoulder part and the rebound rate is 4% to 15% is proposed.

JP 2006-280426 A

However, in the protector of Patent Document 1, when the ball is not rotated and hits straight, the ball can be rebounded to some extent. Because the ball flies from the direction and the ball collides, the shock absorbing effect of the cushioning material is halved, and the ball thrown by the pitcher is subject to intense rotation. There was a problem that the rotation could not be stopped and the movement could not be stopped.
Moreover, in the protector of patent document 1, since the thing of a special material was used as a buffer material, there also existed a problem that a selling price had to be expensive.
Accordingly, the present invention is intended to provide an inexpensive catcher chest protector that can effectively stop the movement of a one-bound ball thrown by a pitcher.

  The chest protector for a catcher according to the present invention includes a protector body in which a plurality of bumps for shock absorption are provided at predetermined intervals on the surface of the base material, and a shock absorber on the surface of the bumps of the protector body. And a rotation regulating sheet that is attached with a gap so as to form a space, is wound around the colliding ball and stops its rotation.

  Further, it is preferable that the rotation restricting sheet is attached so that both sides thereof are opened.

  Furthermore, a shock absorber space is formed on the surface of the protector main body in which a plurality of ridges for impact absorption are provided in the vertical direction at predetermined intervals on the surface of the base material, and the surface of the ridge of the protector main body. As shown in the figure, it is covered with a gap and opened on both sides, and is attached along the groove between the ridges extending in the left-right direction. And a regulation sheet.

According to the chest protector for a catcher according to claim 1 of the present invention, when the ball thrown by the pitcher is one-bounded and hits the surface of the protector of the catcher, the rotation restricting sheet having an impact absorbing space on the back surface While stopping, the impact absorbing space becomes a cushion, and the impact is absorbed by colliding with the ridge, and the movement of the ball can be stopped.
Thus, the bounce of the ball can be effectively prevented by the synergistic effect of the winding effect by the rotation restricting sheet, the impact absorbing effect of the impact absorbing space, and the impact absorbing effect of the ridge.
Moreover, since it has a simple structure in which a rotation restricting sheet is attached to the surface of the protector body, the selling price can be kept low.

  According to the chest protector for a catcher of claim 2, since both sides are open and the shock absorbing space is formed, the rotation restriction sheet is given flexibility, and the flexible rotation restriction sheet is wound around. , Can stop the rotation of the ball.

  According to the chest protector for a catcher according to claim 3, the one bound ball enters the recess of the rotation restricting sheet, and the rotation restricting sheet having the shock absorbing space on the back is wound from above and below to stop the rotation of the ball. While the shock absorbing space becomes a cushion, the impact is absorbed by colliding with the ridge, and the movement of the ball can be stopped.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 relate to a chest protector for a catcher according to a representative embodiment. FIG. 1 is a perspective view, FIG. 2 is an enlarged central end view, and FIG. 3 is an exploded perspective view.

A catcher chest protector P (hereinafter referred to as a protector P) includes a protector body 1 and a rotation restricting sheet 2 as shown in FIGS.
The protector body 1 has a plurality of shock-absorbing ridges 4 provided in a small room shape on the surface of the base material 3 that can be covered over the chest, abdomen, and shoulders with a predetermined interval. is there.
In the protector main body 1 shown in the figure, as shown in FIG. 3, the protruding portions 4 are provided in the central portion in the vertical direction at predetermined intervals, and the elongated protruding portions 4 extend in the horizontal direction. The chest and abdomen are formed. Further, on both sides of the chest and abdomen, ridges are provided in the vertical direction with a predetermined interval, and shoulders and side portions are formed.
These ridges 4 are filled with a foamed synthetic resin such as polyurethane. The ridge 4 absorbs the impact of the ball B that has collided, and various cushioning materials can be employed.

As shown in FIGS. 1 to 3, the rotation restricting sheet 2 is wound around a colliding ball and stops its rotation, and an impact absorbing space 5 is formed on the surface of the ridge 4 of the protector body 1. It is attached with a gap.
In the protector P shown in the figure, a vertically long substantially bowl-shaped rotation restricting sheet 2 is used, which is applied to the surface of the protruding portion 4 at the center of the protector body 1 and both sides are opened so as to have a gap therebetween. Thus, the upper body, the lower side, and the groove portion 6 between the protruding portion 4 and the protruding portion 4 are sewn to the protector main body 1. In the figure, 2 a is an opening of the rotation restricting sheet 2.
As shown in FIG. 1, a recess 7 is formed along the groove 6 on the surface of the rotation restricting sheet 2 attached in this manner, and in the gap between the surface of each protrusion 4 and the rotation restricting sheet 2. The shock absorbing space 5 is formed over the entire left and right direction.
The anti-rotation sheet 2 can be made of synthetic resin, cloth, or a combination thereof, and the rotation restricting sheet 2 can be attached by an adhesive or heat welding.
In the protector P described above, the rotation restricting sheet 2 is attached in the vertical direction of the central portion of the protector main body 1, but it can also be attached to a part of the protector main body 1 or the entire surface of the protector main body 1.
Further, in the illustrated protector P, the rotation restriction sheet 2 is attached with the both sides open to provide flexibility, but the rotation restriction sheet 2 is formed so that the shock absorbing space 5 is formed. It is also possible to close and attach both sides or only one of them. That is, it suffices that at least a middle part of the rotation restricting sheet 2 is attached so as to have a gap with respect to the surface of the protector body 1.
Further, although the rotation stop sheet 2 is a single sheet, it is attached to each ridge 4 using a sheet having a size that can cover each ridge 4. Also good.

FIG. 4A shows the rotation restricting sheet 2 of the protector P described above. Both side surfaces are opened, and the upper side, the lower side, and the groove portion 6 between the protruding portion 4 and the protruding portion 4, As shown in FIG. 4B, only the upper and lower sides of the rotation restricting sheet 2 are sewn with both sides open so as to have the shock absorbing space 5, as shown in FIG. 4 (b). It may be a thing. In the figure, reference numeral 10 denotes a seam.
Further, the rotation restricting sheet 2 in FIG. 4C is sewn in the vertical direction along the surface of the protruding portion 4 in addition to the rotation restricting sheet 2 in FIG.
Further, the rotation restricting sheet 2 in FIG. 4D is sewn in the vertical direction along the surface of the protruding portion 4 in addition to the rotation restricting sheet 2 in FIG.

  A shoulder belt 8, a back belt, and a waist belt 9 are provided on the back surface of the protector body 1.

  According to the protector P described above, as shown in FIG. 2, when the one-bound ball B collides from an oblique direction and enters the recess 7 of the rotation restriction sheet 2, the rotation restriction having the shock absorbing space 5 on the back surface. The seat 2 is wound from above and below to stop the rotation of the ball B, and when the ball B collides with the ridge 4 while the shock absorbing space 5 serves as a cushion, the impact is absorbed and the movement of the ball B is stopped. Become.

Moreover, in the protector P mentioned above, since both sides are open and the shock absorbing space 5 is formed, the rotation restricting sheet 2 is flexible, and in this state, the ball B is in the recess 7 of the rotation restricting sheet 2. By entering, it is possible to stop the rotation of the ball B by winding from above and below.
Thus, according to the protector P, the ball bounces effectively due to the synergistic effect of the winding effect by the rotation restricting sheet 2, the impact absorbing effect of the impact absorbing space 5, and the impact absorbing effect of the ridge 4. Can be prevented.

  Since the protector P described above has a simple structure in which the rotation restricting sheet 2 is sewn and attached to the surface of the protector body 1, the selling price can be kept low.

Next, a description will be given of the results of a comparative test regarding the repulsion distance when the ball collides with the protector P product (Example 1) and the conventional protector (conventional product).
The first embodiment is a protector P in which a rotation restricting sheet 2 is sewn on a conventional product. Specifically, as shown in FIG. 3, the surface of a conventional protector for adults is sewn with a substantially hook-shaped anti-rotation sheet 2, and is projected in the vertical direction at the center of the surface of the protector body 1. The portion 4 is provided, and the size of the protruding portion 4 is about 4 to 9 cm (vertical direction) × about 14 to 21 cm (lateral direction) × about 2 to 3 cm (height). The gap between the portion 4 and the rotation restricting sheet 2 is about 3 cm at the maximum.

In the comparative experiment, Example 1 and the conventional product are suspended in a state where the rubber plate is applied in the batting center, and a direct ball is applied to the Example 1 and the conventional product in a one-bound manner. The method was tried, and the ball was collided 15 times, and the distance of the repulsion was measured.
In addition, the distance from the machine to the protector is set to 17 m, the ball speed is set to 110 km / h, and the balls are made of urethane.
Table 1 summarizes these results.

Table 1 shows that comparing the conventional product and Example 1, it is clear that Example 1 can reduce the repulsion distance compared to the conventional product.
Comparing the average values of these repulsion distances, when applied directly, the repulsion distance of Example 1 can be reduced to 77% compared to the repulsion distance of the conventional product.
When hit by one-bound, the repulsion distance of Example 1 can be suppressed to about 47% of the repulsion distance of the conventional product. The effect by the rotation restricting sheet 2 appears remarkably.
