JPH09669A - Ball throwing and catching exercise boards - Google Patents

Abstract

PURPOSE: To exercise alone for the throwing and cathing of baseball balls to improve the technique by putting, on each of three adjacent boards, a rectangular plate having both upper and lower convex curved surfaces, and giving a function to bend inside at joints between the central board and both right and left boards. CONSTITUTION: A left board 2 and a right board 3 are jointed to a central board 1 to construct throwing and catching exercise boards. A rectangular plate having both upper and lower convex curved surfaces 4 and 5 is put on both upper and lower parts of the central board 1. Similarly, rectangular plates having convex curved surfaces 6, 7, 8 and 9 are put on both right and left boards 2 and 3. Both right and left boards 2 and 3 are slightly bent inside against the central board 1. Their angle of bending is adjustable. Thus, the throwing and catching exercise boards enable the exercising alone for the throwing and catching of baseball balls, and serve for the improvement in technique. They also serve for the catching of balls bouncing off the boards by many players.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION Field of the Invention The ball thrown toward a pitching / ball catching practice board according to the present invention is intended to cause various changes and bounce back, and is used for practice and play of pitching / ball catching. It

[0002]

2. Description of the Related Art Conventionally, in order to perform pitching and pitching / ball-catching practice alone, a player throws a ball on a wall or a wall and catches a bounced ball. When throwing a fly on a flat surface such as a wall or wall, the ball is banded on the ground and applied to a flat surface. When you want to get out, throw the ball on a flat surface and then crawl on the ground.
The pitching and catching practice board installed in the school yard or park is a concrete flat surface.

[0003]

As described above, the pitching and catching practice board in the prior art only provides a flat surface that stands vertically, so it is intended only for control practice. is there. Even if you practice catching the ball on the same board, the effect of feeding the reflexes during catching does not occur much. When a ball is hit on a vertically standing plane, the law of bouncing of the ball is constant, and the rotation of the ball causes some changes. For this reason, the ball muscle of the ball that bounces can be predicted depending on the hitting position of the pitched ball, so that the ball can be prepared in advance, the change is small for catching the ball, and it is monotonous. Also, when practicing pitching, in the conventional technology, the ball hits a flat surface, so the ball that bounces depending on the position where the ball hits does not produce a very different trajectory, so you can accurately check the state of the ball you throw. Can not.

[0004]

[Means for Solving the Problems] As described above, the conventional method cannot be expected to change the ball muscle of the bounced ball, and thus is insufficient as a practice for throwing or catching. Especially when it comes to catching balls, neither practice nor play is interesting. In view of this, in the present invention, a vertically long rigid plywood is provided with an elongated plate-like member having a convex curved surface, which is attached in two upper and lower stages. The material of the board and the curved plate to be attached is not limited to plywood as long as it is a material that gives elasticity to the balls. Three boards configured in this way are horizontally connected so that the left and right boards can be held in a shape that is slightly bent inward with respect to the central board. Various methods such as a plug-in type, a hinge, and a backing plate can be used for maintaining the shape. It is also possible to attach a pile under the board and drive it into the ground. It is also possible to attach a net or a non-elastic material to the side end to suppress the repulsion of the detached ball.

[0005]

[Operation] Two thick, protruding curved surfaces cross the board, the front board stands upright vertically, and the left and right boards bend slightly inward and stand vertically. If you throw a ball on this board, the ball hit between two curved objects will bounce straight. When it hits the upper side of the curved surface, it becomes a fly, and when it hits the lower side of the curved surface, it becomes a fly. When hitting the left and right boards, the ball returns to the inside, but it is not constant depending on how it hits. The ball muscle that bounces back and forth changes with each ball, which requires a sense of tension when catching. For this reason, the player will not get tired of practicing or playing alone, or playing with a large number of people, and will naturally become familiar with the ball and develop motor nerves.

An embodiment will be described with reference to the drawings. FIG. 1 is a perspective view of a pitching / ball catching practice board. The state where the left board 2 and the right board 3 are attached to the central board 1 is shown. Rectangular plate-shaped members 4 and 5 having convex curved surfaces are stretched on the upper and lower stages of the central board 1. Similarly, rectangular plates 6, 7, 8 and 9 having convex curved surfaces are stretched on the left and right boards. Left and right boards 2, 3
Is slightly bent inward with respect to the center board 1.
This folding angle can be adjusted.

FIG. 2 is a sectional view of the pitching / ball catching practice board taken along the line AA of FIG. It shows a state in which rectangular plate-shaped objects 4 and 5 having a curved surface are projected from the board 1 standing upright.

FIG. 3 shows an example of using the pitching / ball catching practice board. It shows the trajectory of a ball that bounces when it hits a board that stands vertically.

[0009]

The pitching / ball catching practice board according to the present invention having the above-described structure is useful for improving the skill by practicing baseball pitching and catching by one person. It is also useful for catching balls that bounce off the board and playing with a large number of people. Even when practicing pitching, if you do not throw the ball at the same position on the board, the ball will bounce in a completely different direction from the expected bounce position of your own ball, so try to throw the ball at the correct position It has an excellent effect on control training. When the pitching / ball catching practice board according to the present invention is actually used, it provides the fun of forgetting the time and engaging in practice.
