JP2001286596A - Toss batting type batting practice machine for baseball - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a toss batting type batting practice machine for baseball used for personal practice without power to train sight for a moving body including meeting and timing by setting the swing starting timing not by the machine, but hitting upward a ball in an arbitrary timing of a trainee himself and by repeatedly practicing hitting a moving ball, not a stationary ball. SOLUTION: This batting practice machine is characterized in that practice balls are set in a ball receiving tray 5, first a pedal 1 is stepped by a foot (left foot of a right batter, right foot of a left batter), a bat is held at the ready, on releasing the foot from the pedal, a slide 3 connected to a wire 2 works, a bar 9 locked by a hook B7 is released so that the bar works as a seesaw to spring up the ball receiving tray 5, thereby driving out a ball upward. The user of a soft ball such as a sponge ball or the like enables practice in an ordinary dwelling house.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0101]

BACKGROUND OF THE INVENTION After a trainer sets a ball on a ball tray and holds a bat, the pedal (1) is depressed with a foot (a right batter is a left foot, and a left batter is a right foot). When the pedal is released at the timing, the slider (3) by the wire (2) connected from the pedal is actuated to cause a recoil of the spring A (4), and the ball set on the ball tray (5) is vertically lifted. Launch in the direction.

2. Description of the Related Art Hitherto, a practicing machine of the tibating type is not suitable for practicing dynamic visual acuity in hitting a stationary ball, and an electric practicing machine requires electric power and a large space. The timing of starting the swing was up to the machine.

[0093]

The present invention has solved these disadvantages. (B) Able to hit moving balls instead of hitting a stationary ball, and to capture and hit the moment of top dead center of a vertically rising ball. (B) Ability to practice hitting alone in a small space without using a motor. (C) The timing of the swing start is not left to the machine, but can be started at any timing of the batting trainee.

[0093]

Means for Solving the Problems (a) First, as for the slider (3), a hook A (6) is installed by a cylinder which moves up and down with a sliding shaft (8) as a core. It is connected to the pedal (1), and the pedal is moved up and down by depressing and releasing the pedal. (B) With the ball tray (5) fixedly installed on the bar (9) pushed down, a hook B (7) for locking the bar was installed. (C) The positional relationship between the hook A (6) and the hook B (7) does not affect the hook B (7) when the slider (3) goes up when the trainee steps on the pedal (

FIG. 5) When the pedal is released and the slide (3) descends, the hook B (7) is affected (FIG. 5).

FIG. 7) Adjusted and installed at a position that functions to release the locked bar (9). (D) The bar (9) released by the function of the hook B (7) causes the spring A (4) to recoil, moves like a seesaw, and moves the ball placed on the ball tray (5) vertically upward. It is a hitting training machine to launch.

[0056]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (a) A seesaw-like bar (9) for playground equipment is at the center, and a ball tray (5) is provided at one end.
Is fixedly installed, and a spring A (4) is installed at the other end, and moves in a seesaw-like manner around a fixed shaft (11) located at the center of the left and right, and moves the ball tray (5) up and down. It is a mechanism to exercise. (B) Hook B (7) near the ball tray of bar (9)
The hook B (7) serves to lock the bar at the bottom dead center of the bar when the ball tray is pushed down. (C) In order to operate the hook B (7), a slider (3) having a hook (A) is installed near the slide shaft (8) as a center, and the slider is connected to a pedal. The wire (2) was fixed. (D) The slider (3) is moved up and down by the action of the trainee stepping on and releasing the pedal with his / her foot, causing the fixed bar (9) to recoil and launch the ball upward. (E) Fine adjustment of the height of the top dead center of the launched ball can be performed with the adjustment screw (10). (F) In the case of using spheres with different gravity due to different materials, the spring A of (4) can be replaced by a spring with different strength or by a rubber string or plate rubber, so that the height of the top dead center can be changed. Can be adjusted. (G) When using balls of different sizes, the ball tray of (5) can be used by replacing the ball tray with a ball tray of the same size. (H) If this main body is installed with an inclination, not only a vertically rising ball muscle but also a parabolic ball muscle can be obtained.

[0006]

(A) With the above-described mechanism, the timing of starting the swing of the batting trainee can be performed at an arbitrary timing of the batting trainee himself, instead of leaving it to the machine. (B) By repeatedly practicing a moving ball, it becomes a training of dynamic visual acuity training as well as swing timing and meet. (C) By using a soft sponge ball for the practice ball, you can practice hitting indoors in a normal house.
