本考案はアーム式ピツチングマシーンにおける
投球音の消音装置に関するものである。[Detailed Description of the Invention] The present invention relates to a pitching sound muffling device for an arm-type pitching machine.
従来のアーム式ピツチングマシーンにあつては
投球ごとに投球スプリングが強く振動し、ピツチ

ても、バツテイング練習のさまたげになるもので
あつた。 In conventional arm-type pitching machines, the pitching spring vibrates strongly every time a pitch is pitched, which resonates with the frame of the pitching machine body and generates a loud noise. This noise not only causes noise pollution, but also interferes with batting practice for users of arm-type pitching machines.
この音の発生原因は投球スプリングの両端の引
張部の動きの相違及び振動力の吸収技術が全く施
されていなかつたことによる。 This noise is caused by the difference in the movement of the tension parts at both ends of the pitching spring and by the lack of any vibration force absorption technology.
そこで、本考案は投球アームの主軸側と反対方

グマシーンにおける消音装置を提供することを目
的とする。 Therefore, the present invention is an arm-type pitcher that can eliminate the loud noise that was generated with each pitch by making the tension part of the pitching arm in the opposite direction to the main axis freely rotatable and absorbing the vibration force. The purpose of the present invention is to provide a sound deadening device for a running machine.
以下、図示の実施例に従つて説明する。 The following will explain the embodiments shown in the drawings.

こすものである。 Fig. 1 is a side view showing an example of an arm-type pitching machine according to the present invention.The pitching machine will be explained according to this figure.In the figure, 1 is the base frame of the pitching machine, and 2 is the pitching It is an arm. The pitching arm 2 is attached to an arm main shaft 3, rotated slowly by a motor M, and causes a pitching action by the attractive force of a pitching spring 4 connected to the arm main shaft 3 by a crank mechanism.

ある。 The tip of the pitching spring 4 is attached to the crank mechanism of the arm main shaft 3 by a spring attachment 5, and the rear end, that is, the end in the opposite direction, is usually fixed to the base frame 1 by a tensioning part 6 having a tension adjustment mechanism. has been done. In addition, 7 in the figure is a tension adjustment handle.

距離に設けることが好ましい。 The present invention fixes the shaft body 8 to either one of the tension part 6 and the tension part attachment location, fixes the radial flat bearing part 9 to the other, and rotates the shaft body 8 on the radial flat bearing part 9. It is characterized by being inserted and installed freely.
According to the partial cross-sectional plan view of the vicinity of the pitching spring mounting portion shown in FIG. 2, the shaft body 8 is fixed to the base frame 1, and the radial flat bearing portion 9 is fixed to the tension portion 6 side. The shaft body 8 and the flat bearing part 9 are preferably provided at a distance from the pitching spring 4 in the tension part 6 in order to lower the vibration frequency.

回動自在に装着している。 The details of the shaft body 8 and the radial flat bearing part 9 are shown in the exploded cross-sectional view in FIG. 9 is a radial flat bearing portion formed in the tension portion 6, and a radial flat bearing 11 having appropriate frictional resistance is mounted on the inner circumferential surface of the bearing portion 9. The shaft body 8 is inserted into the radial plain bearing 11, and both are rotatably mounted by an insert plate 12.

チングマシーンの静かな利用が可能であり、実用
的なものである。 Since the present invention is constructed as described above, when an arm-type pitching machine using the present invention is used, the pitching spring 4 contracts with the pitching motion, and at the same time, the spring attachment device 5 instantly rotates. This causes the pitching spring 4 to vibrate, but the tension part 6 is caused by the radial flat bearing part 9.
Since it is rotatable, vibrations are not transmitted to the base frame 1, thereby preventing resonance and making it possible to eliminate vibration force by the appropriate frictional resistance of the radial flat bearing 11. Therefore, according to the present invention, only very small noise is generated, and the arm type pitting machine can be used quietly, and is practical.
