Description

[Detailed Description of the Invention] In general, there are two types of pinching machines used for baseball batting practice: those that place a pole on the arm and use rotational force to pitch the ball, and those that fire the pole from within a firing tube. It is being

However, in either case, it is impossible to pitch a curve ball at a certain speed or above a certain course, and it is difficult for batters to concentrate on practicing courses and holes that are weak to them in a short period of time. Therefore, the present invention was made by focusing on this point,
Provides a pitching machine that continuously pitches pitches and breaking balls with speeds above a certain level on a certain course, allowing batters to concentrate on short courses and fastballs to overcome weak pitches or fastballs, or to get used to them before a game. The gist of this is that a firing means capable of adjusting the strength is provided at the rear of the firing tube, a resistance for controlling the rotation of the ball is provided on the inner surface near the front of the firing tube, and a A pitching machine is characterized in that a ball contacting part is provided with rotation imparting means, and the installation angle and position of a launch tube can be changed.

Next, an example of implementation of the present invention will be described with reference to the drawings.

1 in the figure is a pitching machine according to the present invention, and this pitching machine 1 has a stationary leg 2, which is extendable and foldable. A bracket 4 is provided at the top of the stationary leg 2 via a rotary plate 3, and this bracket 4 has a mounting portion 6 for the launch tube 5.
is pivoted to the fine grain.

This installation part 6 has a cross-sectional shape of 7, and a saucer 7 having an upwardly arched shape that matches the outer peripheral surface of the launcher 5 is fixed to its wide open upper surface, and the launcher 5 is mounted on the saucer 7. The device is placed on the device and secured with a fixing device such as a thumbscrew.

The launch tube 5 is equipped with a push plate 9 that is slidable along the inner surface and has a guide bar 8 on the rear surface near the rear of the interior thereof, and the front surface of the push plate 9 is equipped with a support plate 9 that is attached to a pole such as a pole bearing. A rotation imparting means 11 for applying rotation is provided. Also, a coil spring 12 is elastically installed between the rear surface of this push plate 9 and the rear surface of the firing barrel 5, so that the push plate 9 is always biased in the 1) 1j direction. It has become something that will be done.

Furthermore, the guide/toe-8 is pulled toward the push plate 9/<
-13 is fixed, and this tension lever 13 has its tip protruding outward from a groove 14 formed on the upper surface of the firing barrel 5. A plurality of branch grooves 15 are formed in the middle of this split groove 14, so that the compressive strength of the coil spring 12 can be appropriately selected.

In addition, the tip of the firing tube 5 is provided with an attachment 16 that can be detached and replaced to make the inner diameter the same as that of the firing tube 5, and the inner surface of this attachment 16 is equipped with an attachment 16 that controls the rotation of the ball B to create a curved ball. A resistor 17 made of rubber or the like is provided.

The position of the resistor 16 can be changed depending on the type of curve ball, and if a special screw pole or the like is desired, it can be formed into a spiral shape.

In the figure, reference numeral 18 indicates the pole for sequentially feeding the pole into the launch tube 5, and reference numeral 19 indicates the sight.

The pitching machine according to the present invention is constructed as described above.

The stationary leg 2 is extendable and retractable, and the rotating plate 3 and the launch tube 5 are
Since the shape of the ball can be freely narrowed, the firing position and aiming point of the ball can be freely selected, and the presence of the branch groove 15 allows
The same compression strength can be adopted for the coil spring 12, and the speed can be changed freely.

Furthermore, the presence of the resistance 17 allows the batter to freely throw curveballs, allowing the batter to practice hitting the target pole in a short period of time.

The embodiment shown in the drawings is an example, and the scope of its application may include, for example, making the lever 13 a set of triggers, adding electronic control, denying the presence of a stationary leg, etc., within the scope of the present invention. This invention has many excellent advantages,
Implementing the present invention has enormous practical value.
