【考案の詳細な説明】
この考案は、野球の主として打撃練習及び野球
用具のテスト等に使用するピツチングマシン（投
球機械）の改良に関するものであり、秒速60ｍ以
上のスピードボールを出すことを目的とする。[Detailed description of the invention] This invention relates to the improvement of a pitching machine used mainly for batting practice and testing of baseball equipment, and its purpose is to produce a ball with a speed of 60 m/s or more. shall be.
ピツチングマシンは種々実用に供しているが、
ボールのスピードは秒速40ｍ程度のもので、ボー
ルとバツトの衝突時の相対速度に相当する秒速60
ｍ以上のスピードを出せるものが提供されていな
い。これは従来のものはボールを加速する回転ロ
ーラーが一対であるため、ボールは初速度０から
急加速となり、ローラーとの間でスリツプして高
速が出せないことに起因していることが判明し
た。 Pitching machines are used for various practical purposes,
The speed of the ball is about 40 m/s, which is 60 m/s, which corresponds to the relative speed at the time of collision between the ball and the bat.
There are no devices available that can achieve speeds higher than m. It turns out that this is because the conventional system has a pair of rotating rollers that accelerate the ball, so the ball accelerates rapidly from an initial speed of 0, and the ball slips between the rollers and cannot reach high speeds. .
そこで、この考案は対向して反対方向に回転す
る２対のローラーの間にボールを通し、ボールを
二段階で加速して秒速60ｍ以上の高速を得ること
に成功したもので、その実施例を図面に基づいて
説明する。 Therefore, in this invention, the ball is passed between two pairs of rollers that face each other and rotate in opposite directions, and the ball is accelerated in two stages to achieve a high speed of more than 60 m/s. The explanation will be based on the drawings.

ことを特徴とするピツチングマシンである。 That is, a pair of motors 2, 2' and two pairs of shafts 3, 3', 4, 4' are provided on the left and right sides inside a suitable frame 1, and a pulley 5,
Fix 5', 6, 6', 7, 7'. The pulleys 6', 7' have a large diameter, and a V-belt 8 is mounted thereon, and the upper ends of the shafts 3, 3', 4, 4' protrude from the frame 1 to fix rollers 9, 9', 10, 10'. . Rollers 9, 9' and 10, 1 from the outside of the pedestal 1
This pitching machine is characterized in that a ball guide rail 11 is disposed in the middle of 0', and a ball feeding tube 12 is provided at the tip of the guide rail.
なお、図面は省略したが、上記実施例と同じ要
領でモーターとローラーをそれぞれ一対増加し
て、三段階でボールに加速することも可能であ
り、この場合、架台は大型になるが、ボールの発
射スピードは一層早くなるものである。 Although the drawings are omitted, it is also possible to add one pair each of motors and rollers in the same manner as in the above embodiment to accelerate the ball in three stages.In this case, the frame will be larger, but the ball will be The firing speed will be even faster.
この考案は上記のように構成したから、左右一

反対方向に回転するローラー９′，１０′でボール
に加速するが、該ローラーの回転数を遅くしてあ
るから、ボールとローラーとの間でスリツプする
ことなく高速回転するローラー９，１０に入り、
ボールに十分な加速を与えて発射する。 Since this invention is constructed as described above, when the left and right pair of motors 2, 2' are rotated in opposite directions, the pair of left and right motors 2, 2' are rotated through the pulleys 5, 5', 6, 6', 7, 7' and the V-belt 8. The rollers 9, 9' and the other pair of rollers 10, 10' both rotate in opposite directions. In this case, the pulleys 6', 7' of rollers 9', 10' are
Since the diameter is larger than that of the rollers 9', 1
The rotational speed of 0' is slower than the rotational speed of rollers 9 and 10. Therefore, the balls thrown in from the ball throwing tube 12 are guided by the ball guide rail 11 and accelerated into balls by the rollers 9' and 10' which rotate in opposite directions, but the rotational speed of the rollers is slowed down. , enters the rollers 9 and 10 that rotate at high speed without slipping between the ball and the roller,
Fire the ball by giving it enough acceleration.
このように、第一段階はボールとローラーとの
間でスリツプしない程度に加速し、初速を与えら
れたボールを更に高速回転するローラーに入れて
二段階の加速をするため、発射するボールのスピ
ードは秒速60ｍ以上の高速になる。 In this way, in the first stage, the ball is accelerated to the extent that it does not slip between the ball and the roller, and then the ball, which has been given an initial velocity, is placed into a roller that rotates at a high speed and then accelerated in two stages, so the speed of the ball to be launched is increased. becomes a high speed of more than 60 m/s.
かくて、実際のバツテイングに近い相対速度で
ボールやバツトの各種のテストができるのはもち
ろん、打撃練習においてもスピードボールを打つ
練習に有益である。 In this way, it is possible not only to perform various tests of balls and bats at relative speeds close to actual batting, but also to practice hitting speed balls during batting practice.
