Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a batting device for baseball catching practice.

BACKGROUND ART Conventionally, a batting machine has been known as a baseball practice machine. However, fielders' catching practice was mostly done by batting coaches and others.

Problems that the invention aims to solve: However, in order to consistently hit accurately against outfielders, infielders, and even catchers, advanced batting techniques are required, especially for short periods such as intervals of several seconds. It was extremely difficult to practice catching and hitting accurately each time.

Therefore, in tennis and the like, a ball launcher has been devised, as disclosed in Japanese Utility Model Application Publication No. 59-61065, which can launch a ball by arbitrarily selecting the launch angle of the ball.
However, with this method, it is not possible to hit a ball similar to what a baseball batter actually hits with a bat, and it is also difficult to hit a ball that is heavy, fast-moving, and difficult to catch. It was something I couldn't do.

Means for Solving the Problems The present invention was developed in view of the above-mentioned problems, and in order to solve the above-mentioned problems, the ball is caught at a predetermined position extending from the front to the rear of the arc-shaped ball placement part with a predetermined diameter. A practice ball can be freely loaded, and a cylindrical or disc-shaped ball with a diameter of a butt is mounted on a batting device arranged in a batting ball installation part in order to centrifugally rotate and bat the catch practice ball, and the ball is rotated centrifugally in the radial direction of the actual game. To provide a batting device for ball catching practice, characterized in that a batting part is vertically attached and a weight material is attached to the rear of the batting part.

Example The present invention will be explained below based on examples.

FIG. 1 and subsequent figures show an embodiment of the present invention. The striking device 1 is 1000 mm x 1000 as shown in Figures 1 and 2.
It is formed into a box shape with a size of about mm x 500 mm, and a batting ball installation part 4 with a passing interval 3, which is a passage for the striking device 2, is arranged in a semicircular arc shape approximately in the center of the box. A catching practice ball 5 mounted on a batting ball installation part 4 is arranged so as to be freely hit by a hitting device 2. In the batting ball setting section 4, as shown in FIG. 1, a narrow flat plate-shaped batting ball setting material 6 with a circumferential angle of about 90 degrees is placed at intervals such that catching practice balls 5 can be placed as shown in FIG. A batting ball locking device 7 is arranged in parallel around the center of the batting device 1, and around the periphery, a batting ball locking device 7 for placing the catching practice ball 5 between the batting ball installing materials 6 is attached to the batting ball installing material 6. It is movably arranged along the periphery. The ball-hitting ball locking device 7 is fitted onto a center shaft 8 mounted at the center of the ball-striking installation portion 4 as shown in FIG. As shown in the figure, an L-shaped member 10 is provided, and a locking member 11 with a predetermined elastic force such as a coil spring is attached so as to protrude downward in a semicircular arc shape as shown in the figure. The lower end of the arc is brought into contact with the upper part of the catching practice ball 5 so that the catching practice ball 5 can be placed between the arc-shaped batting ball setting materials 6. The ball locking device 7 is rotatably connected to a belt suspension device such as a link lever device or a timing belt (none of which is shown), and is stopped at an arbitrary position on the ball mounting material 6. ,
This allows him to freely hit both liner and fly balls. As shown in FIGS. 1 and 2, the impact device 2 is formed by protruding a rigid rod-like body 12 from the center of a central shaft 8.
A striking part holding part 13 is provided at the tip of the striking part holding part 13, and a narrow cylindrical striking part 14 having approximately the diameter of the butt is provided at the side end of the striking part holding part 13 in the direction of rotation perpendicular to the direction of the rotation radius as shown in FIG. Even though the batting device 2 is rotated in the vertical direction, the catching practice ball 5 can be hit as in a real game. Moreover, the hitting part holding part 13 is hollow as shown in FIG. weight material 16
moves to the hitting section 14 side so that the catching practice ball 5 can be hit. At one end of the center shaft 8 of the striking device 2, a short peg 17 is provided protruding at right angles to the rod-shaped body 12, as shown in FIG. 1, and at the other end, as shown in FIG. It is connected eccentrically to an elastic pressure accumulating device 18 that performs crank motion and is formed of two or several spring coils with elastic force, and performs a quick return operation using a swing link mechanism. As shown in FIGS. 1 and 2, a pin 19 is further provided protruding from the side end of the central shaft 8 of the impact tool 2 formed in this way, so that the above-mentioned punch 1
A sprocket wheel 20 of a predetermined diameter is fitted so as to rotate the impact device 2 by contacting the impact device 7, and is suspended and connected via a chain 22 to a sprocket 21 pivotally attached to the lower part of the impact device 1. It is rotatably driven by an electric drive device 23 such as a geared motor with a reduction ratio of . Electric drive device 23
can be controlled by the control device 24 (by providing a detector in the impact device if necessary) so that it can be operated at variable and appropriate intervals from several seconds to more than ten seconds. Reference numerals 25 and 26 indicate brakes and brake bands for cushioning and receiving the hit batting device 14, and 27 indicates catching practice balls 5 from a ball supply device (not shown) such as a hopper to the batting ball installation portion 4 on the left and right, respectively. A ball supply port 28 for sorting and supplying balls is a carrier for moving the striking device.

Function: Therefore, the batting ball locking device 7 of the batting ball setting part 4 is
As shown in A of the figure, if the batting device 2 is installed slightly forward of the central shaft part, and the control device 24 is activated to drive the electric drive device 23, one catching practice ball 5 can be hit from the ball feeding device. At the same time, the striking device 2 is rotated by being pushed by the pin 19 of the sprocket wheel 20, and the elastic pressure accumulating device of the crank motion is eccentrically connected in the middle. 18, the ball is rapidly accelerated and rotated, and the catching practice ball 5, which is locked by the hitting ball locking device 7, is hit. At this time, since the catching practice ball 5 is placed slightly forward of the central axis of the batting device 2 as shown in A, the catching practice ball 5 is placed in the hitting section 1 of the batting device 2.
4, the ball is hit downward as shown in the diagram, and becomes a ground ball, allowing fielders to practice catching ground balls.

In addition, if the batting ball locking device 7 is installed slightly behind the center axis of the batting device 2 as shown in FIG. It is a ball that is hit, turns into a liner, and becomes a fielder's liner catching practice.

Furthermore, if the ball locking device 7 is installed in the positions C and D in the figure, the ball will be a fly ball, and especially in the latter case, the catcher will be able to hit a fly ball.

In this way, a single batting device can hit ground balls, liners, and fly balls, and can also accurately repeat batted balls in a predetermined direction at short intervals of several seconds to over ten seconds. be.

In particular, in this embodiment, since the percussion device is rotated in the vertical direction, the device can be formed stably and compactly, and since the bat-shaped percussion part is vertically attached to the percussion device, the percussion part can be moved horizontally. It is possible to hit a catch practice ball as if it were swung in a straight line, and the ball can be hit with the same rotation as in a real game. In addition, as shown in Figure 3, the ball is hit slightly below the center of the catching practice ball with the hitting section so that the ball rotates from the bottom to the top, but the height adjustment and installation of the hitting section is difficult. It is also possible to hit balls with various rotations by changing the angle or adjusting the height of one of the hitting installation parts.

In addition, in this example, since the weight material is movably loaded in the batting unit holding part, the weight of the entire batting device can be reduced, and yet a strong impact force is added to the instantaneous force of the catching practice ball. Moreover, it is preferable because it can be struck like a shotless hammer.

The striking part is preferably made of the same material as the bat, such as wood or metal, but it may also be made of carbon or ceramic material, or may be formed integrally with it.

Furthermore, as a batting ball locking device, the locking member 11 can be bent forward slightly easily, and the stopper 29 can be installed tall as shown in Fig. 3, making it difficult to bend backwards.
The catching practice ball 5 can be securely latched to the semicircular arc-shaped batting ball installation part 4 from the front part to the rear part, and is latched by coming into contact with the catching practice tool so that it can be hit with less resistance. However, it is also possible to lock the catching practice ball by fixing it in a predetermined position.Furthermore, as a locking means, a predetermined part of the batting ball installation part can be recessed, or it can be pressed lightly from the top, etc. as appropriate. This is something that can be done.

In addition, in the above embodiment, the batting ball installation part was set in the vertical direction and the batting device was rotated in the vertical direction. It can also be made to strike in such a way that it cuts each time.

Effects of the invention As described above, with the present invention, by centrifugally rotating the hitting part, it is possible to accurately hit ground balls, liners, and fly balls in short periods of time, such as several seconds to more than ten seconds. . In addition, since a cylindrical or cylindrical hitting part with the diameter of the bat is attached to the hitting device in a manner perpendicular to the direction of the rotation radius, even if the hitting device is rotated vertically, the hitting portion remains the same as the batter's butt swing. You can hit a catching practice ball as if it were swung horizontally, and you can practice catching a ball with the same rotation as in a real game. Furthermore, it is possible to hit catching practice balls with instantaneous strong impact force, and it is possible to hit balls that are fast, have heavy pitches, and are difficult to catch, thereby significantly improving ball catching techniques. I can do it.
