Abstract

PROBLEM TO BE SOLVED: To arbitrarily change the discharging direction of a ball by disposing a hitting part provided with a hitting surface in a curved surface shape on the tip of an arm pivotally supported between side plates, movably forming a ball holding part on the appropriate part of a base plate upper surface and hitting and discharging the ball in the hitting part of the driven and rotated arm. SOLUTION: At the time of use, the ball is set between the holding bars 26 of a slide device part A first. Then, an arm driving motor supported at the intermediate part of the side plates 2 is operated and the wind-up of a coil spring is started through gear trains 5 and 6. After winding up the spring, an electromagnetic solenoid 18 is operated and a stop mechanism to the arm 7 is released. Thus, the arm 7 starts rotation by the restoration force of the coil spring and passes through a lowest position and the hitting part 8 in a spherical surface shape at the tip of the arm hits the ball held between the holding bars 26 and discharges the ball. The arm 7 is abutted to a stopper 16 and made to stand still at the time of returning to a top position thereafter.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for shooting a ball in an arbitrary direction toward a batter during toss batting.

[0002]

2. Description of the Related Art Conventionally, toss batting has been performed during practice in baseball or the like, but another person throws a ball at an appropriate position toward a batter, and the batter hits the ball with a bat. As shown in the invention, there is no device that fires a ball for toss batting at an arbitrary position by a mechanical device instead of a human.

[0003]

Conventionally, in the toss batting method, as described above, a person throws a ball at a batter to perform the toss batting. In other words, it is impossible to practice unless two people are paired. . In recent years, toss machines,
In other words, a device for throwing a ball at the batter's hand has been developed, but since the launch direction of the ball is constant, only a beginner can benefit. The practice of hitting with a pitching machine is useful for more than medium hitters, but requires a large space as a practice location, and the arrival position of the ball, that is, the strike zone is uncertain. The present invention was invented in order to solve the problems related to the conventional hitting practice means as described above, and aims to provide a device for practicing toss batting more efficiently. is there.

[0004]

As a means for solving the problems, the present invention employs a curved surface at a hitting portion at the tip of a rotating arm, makes a ball holding portion movable, and can arbitrarily change the direction of a shot ball. I can do it. That is, the side plates are opposed to each other on the base plate, the arm is pivotally supported between the side plates, and a hitting portion having a curved hitting surface is provided at the end of the arm, while the ball holding portion is moved to an appropriate position on the top surface of the base plate. It is provided so as to be capable of being driven by a driving source and configured to rotate a hitting portion at an end of an arm which hits a held ball and shoots the ball in an arbitrary direction. The present invention is a toss batting apparatus having the above configuration.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to use the present invention, a ball is first set on a ball holding section. Next, when the drive source is driven, the arm starts to rotate, and the hitting portion at the tip of the arm applies an impact to the ball and can fire the ball.
Since the hitting portion at the tip of the arm has a curved surface, by changing the position of the ball holding portion, the direction of hitting applied to the ball changes, and therefore, the ball can be fired in any direction by this adjustment. .

[0006]

Embodiments of the present invention will be described below. In the drawing, reference numeral 1 denotes a rectangular base plate, 2 denotes a side plate that stands upright on the base plate, and 3 denotes a top plate that is fixed to an upper portion of the side plate. 4
Is an arm drive motor attached to the side plate, 5 is a drive gear attached to the motor shaft, and 6 is a driven gear provided at a position meshing with the drive gear. This driven gear
It is fixed to a shaft rotatably installed between the inner surfaces of the side plates. 7
Is an arm attached to the shaft, and a hitting portion 8 having a substantially spherical portion is fixed to the tip of the arm. Reference numeral 9 denotes a coil spring wound around the boss portion of the driven gear. One end of the coil spring is fixed to a pin 10 projecting from the boss portion, and the other end is fixed to a pin 11 projecting from the arm side. You. Reference numeral 12 denotes an L-shaped buffer spring formed by bending a steel plate, and is attached to a top plate above the arm. Reference numeral 13 denotes a holder having a notch, which is attached to a rotating shaft end rotatably held by holding portions 14 and 15 attached to the top plate, and an end of a stopper 16 between each holding portion. Is attached. Also, in the notch of the holder,
A transmission shaft 17 is pivotally supported, and the other end of the transmission shaft is attached to a movable portion of an electromagnetic solenoid 18 attached to a lower portion of the top plate.

A slide unit A is provided on the base plate at a position slightly away from the side plate standing position. The sliding device is for sliding the plate in a two-dimensional direction. This device first has a U-shaped base 20.
Are provided, and three rods are provided in parallel between opposing side surfaces of the base. Among them, a male screw is engraved on the center rod and is rotatably held, and one end thereof is connected to a shaft of a lower adjustment motor 21 mounted on a side surface of the base. Also, a movable base 22 having the same shape as the base is provided,
Three holes are drilled in parallel in this movable base, and the above-mentioned rod is inserted. However, a female screw is formed on the inner surface of the central hole, and is screwed with a male screw. . Three rods are similarly provided on the movable base, and a slider 23 is provided in the same relationship as the base and the movable base. An upper adjustment motor 24 is attached to the side of the movable base. A plate 25 is attached to the upper surface of the slider, and the front surface of the plate is bent downward. Then, two holding bars 26 are erected and fixed in parallel on the upper surface of the front end of the plate. The above is one embodiment of the present invention.

When using the present invention, first, a ball is set between the holding rods of the slide device. Next, the arm drive motor is operated to start winding the coil spring. When the electromagnetic solenoid is operated after the spring is wound up, the transmission rod 17 moves, the holder rotates, the rotation shaft rotates, and the tip of the stopper moves upward. It is released. Then, the arm starts to rotate by the return force of the coil spring, passes through the lowermost position, hits the hitting portion at the tip of the arm against the ball, and the ball is fired by the impact. The arm then continues to rotate and returns to the uppermost position, resting on the stopper. The arm is given a rotational force by the return force of the coil spring,
Energy is absorbed by the collision with the ball. Therefore, in the present invention, a little extra coil spring is wound up, and care is taken to return the arm to the initial position. Further, since the arm rotation time is shorter than the winding time of the coil spring, the arm drive motor starts operating before the rotation of the arm starts. The rotation of the motor causes the drive gear to rotate, and is somewhat decelerated so that the driven gear also rotates.
A coil spring is wound around the driven gear, and one end is fixed to the pin 10 and the other end is fixed to the pin 11. Accordingly, the spring is wound up by the rotation of the gear, and the returning force of the wound-up spring acts in a direction for rotating the arm, and the arm can be returned to the initial position. In this example, a buffer spring is provided to reduce the impact between the arm and the stopper. In other words, the rotating arm comes into contact with the lower surface of the buffer spring, and further rotates while pushing up the spring. However, the return force of the spring weakens the arm rotating force, and the softer arm hits the stopper end and stops.

In this embodiment, a slide device is provided so that the ball set position can be changed. In this slide device, the movable table moves in a one-dimensional direction with respect to the base, and the slider moves in a direction perpendicular to the base with respect to the movable table. Therefore, by combining this, the slider and the plate can move freely within a predetermined range in the two-dimensional direction. The ball is set between the holding rods located at the end of the plate, and the hitting portion located at the end of the arm has a curved surface. Therefore, as shown in FIGS. By changing the direction, the hitting direction applied to the ball changes, and the ball can be hit in any direction. In this example, the ball position is changed by the two-dimensional sliding method, but a ball position changing means by another method may be used. As described above, according to the present invention, it is possible to obtain a device capable of training by firing a ball in an arbitrary direction.

[0010]

According to the present invention, since the hitting portion has a curved surface and the position of the ball holding portion, that is, the position of the ball can be changed, the firing direction of the ball can be changed arbitrarily. Thus, it is possible to provide a useful device that can make the ball projection direction to the batter rich.
