[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot pedal device for a drum foot pedal used for playing a percussion instrument such as a drum, which function can be directly operated by a beater to perform the performance. About.

[0002]

2. Description of the Related Art Conventionally, a foot pedal device as shown in FIG. 4 has been used as an instrument used for playing percussion instruments such as drums. When playing a drum using this foot pedal device, first place the device at the front of the drum of a set of prepared drum sets, and then press the pedal to strike the drum with the beater that moves in conjunction with it. It is a device that sounds. In the following, the conventional basic structure shown in FIG. 4 will be briefly described. First, two fixed columns are erected at the end of a rectangular base, and at the center of a shaft rod having a length extending right and left. A spring is provided at one end where a shaft rod having a shaft equipped with a gear pillow and a beater is rotatably combined with the support hole at the upper end of the two columns,
Further, as a means for rotating the beater, an end of a chain provided at a front end of a pedal large enough to put a foot thereon is hooked on the gear chain, and on the other hand,
The rear part of the pedal is hinged to the base. Further, in addition to the above, there has been provided a technology in which an improved foot pedal is provided as disclosed in JP-A-10-171446.

[0003] This apparatus has the above-described structure, and when a foot placed on a pedal is depressed during a performance, the gear pulley rotates in conjunction with the downward movement of the chain. In conjunction with that, the shaft with the beater also moves forward,
A device that beats a drum with a beater. When the foot is released, the pedal returns upward due to the spring force provided at the shaft end, and the shaft and beater are restored to their original positions. Incidentally, Japanese Patent Laid-Open No. 10-
The technology shown in 171446 is a foot pedal device, in which a foot pedal that rotates by being connected to a heel plate fixed to a base is effectively hinged without gaps, thereby reducing noise and power loss due to backlash. It is a technology of connection structure of foot pedal that can reduce the drum performance.

[0004]

An artist who enjoys playing a drum using such a device or who plays a role in playing a drum also contributes as a device for making daily efforts to further improve the performance technique. However, while the above-mentioned foot pedal device is effective for playing a drum, the following inconveniences occur in actual playing for structural reasons. First, the means for rotating the shaft equipped with the beater in conjunction with the pedal connected to the heel part fixed to the base, the pulley fixed to the shaft rod rotatably combined with the two columns Since the gear pulley and the end of the pedal are connected by a chain, the engagement between the gear pulley and the chain is a mechanical system with a gap involving uneven teeth. Naturally, when they are involved, noise due to gaps or friction due to gaps may occur, and care and management must always be performed so that rust, dust, and the like do not adhere to the engaging portions.

[0005] In addition, even if the gap between the engaging portions is minimized, it cannot be completely prevented, so that a loss of force occurs due to the gap. Further, a spring for restoring the gear pulley and the shaft with a beater is required. Since the shaft is rotatably supported by the two pillars, the shaft is rotatably supported by the two pillars. This is a foot pedal device that cannot be said to be a power transmission means that smoothly and accurately interlocks with the rotation of the gear pulley because it causes friction with the holding hole of the existing column or causes a backlash. Such rattling and noise are small, but not only for professional musicians who are striving to make the music even better, but also for the audience listening to it. It is hoped that the factors that cause power loss will be reduced to the utmost. However, since the conventionally provided device is a power transmission means that constitutes a mechanical element, further improvements will be made in order to make the playing instrument satisfactory to the user. We have been looking for a foot pedal device that has been implemented, but at present there was no device that met our expectations.

[0006]

SUMMARY OF THE INVENTION A foot pedal device for playing a drum according to the present invention eliminates the inconveniences and disadvantages of the prior art described above. In the power transmission means with the pulley, to eliminate rattling and noise factors, and to operate smoothly, first, the support arm with the support arm fixed to the base should be one, and the support The member that transmits the power of the pedal to the pulley that rotates in combination with the fixed shaft is connected by a strip made of leather or a synthetic resin material, which is a smooth member with little play and little friction. The spring for restoring the pulley is
By providing a spring directly between the support arm fixed to the support and the pulley, it is possible to prevent rattling and power loss due to reducing friction points, and to make the beater's reaction during performance smooth and operate smoothly A foot pedal device is constructed.
