Description

そして本発明は前記目的を達成するためリム並びにハブ軸からなるホイールを回転体とし、このホイールのハブ軸が可搬台車上のマシンフレーム軸受に支持されて観覧車状態に取り付けられ、モータによって時計方向に回転させられるものである。前記リムに近接して設けたボール供給器からホイールが回転する所定の回数に対してボール１個を、時計の針に見立てた際の時刻でおよそ９時から１０時付近で供給されるボールは、リム上からアームを経由してハンドで受け入れし、ホイールの回転でボールに遠心力を与える。そしてホイールが回転する所定の回数を課した最終回転を終える直前の時計時刻１１時付近で、投球アームとハンド凹部の開口面を並行にすべきハンドを丁番で回動させ、投球アームの旋回並びに撓りによってボールに加えられた遠心力で前方に発射する。 In order to achieve the above object, the present invention uses a wheel composed of a rim and a hub shaft as a rotating body, and the hub shaft of this wheel is supported by a machine frame bearing on a portable carriage and attached in a ferris wheel state. It can be rotated in the direction. A ball supplied from approximately 9 o'clock to 10 o'clock at the time when one ball is regarded as a clock hand for a predetermined number of times the wheel rotates from a ball feeder provided close to the rim is It is received by the hand from above the rim via the arm, and centrifugal force is applied to the ball by rotating the wheel. Then, around 11 o'clock clock time just before the final rotation that imposes a predetermined number of rotations of the wheel, the throwing arm and the hand that should have the opening surface of the hand recess in parallel are rotated with a hinge to turn the throwing arm. At the same time, it is fired forward by the centrifugal force applied to the ball by bending.

前記リムに近接して設けたボール供給器からホイールが回転する所定の回数に対してボール１個を、時計の針に見立てた際の時刻でおよそ９時から１０時付近で供給されるボールは、リム上からアームを経由してハンドで受け入れし、ホイールの回転でボールに遠心力を与える。そしてホイールが回転する所定の回数を課した最終回転を終える直前の時計時刻１１時付近で、投球アームとハンド凹部の開口面を並行にすべきハンドを丁番で回動させ、投球アームの旋回並びに撓りによってボールに加えられた遠心力で前方に発射する。 A ball supplied from approximately 9 o'clock to 10 o'clock at the time when one ball is regarded as a clock hand for a predetermined number of times the wheel rotates from a ball feeder provided close to the rim is It is received by the hand from above the rim via the arm, and centrifugal force is applied to the ball by rotating the wheel.

以下本発明の実施例を図１〜図７に示す具体例に基づいて説明する。図１で示した装置の平面図において、ボールを発射する右側が装置の前方で、左側はその後方である。 Embodiments of the present invention will be described below based on specific examples shown in FIGS. In the plan view of the device shown in FIG. 1, the right side for launching the ball is the front of the device, and the left is the back.

図５でハンド１０にボールＢ受け入れから発射までの１サイクルが終わると、ホイール４が一回転して新たに供給されるボールをハンド１０が受け入れし、その後前記のサイクルを繰り返すことによって連続的に打撃練習ができる実施例を示した図１〜図７までの関連各図である。 When one cycle from the acceptance of the ball B to the firing in the hand 10 in FIG. 5 is completed, the hand 10 accepts a newly supplied ball by making one rotation of the wheel 4, and then continuously by repeating the above-described cycle. It is each related figure to FIGS. 1-7 which showed the Example which can perform batting practice.

Claims
