Description

[Detailed explanation of the invention] This invention is designed to change the tone quality of the guitar strings so that when it is fitted into the neck of the guitar, it can be easily moved along the neck with one hand operation without having to remove it from the neck each time. This is about the capo tasto.

Hereinafter, the present invention will be explained with reference to the embodiment shown in the drawings. The capo tasto 1 includes a pressing piece 3 made of hard synthetic resin that presses the outside of the surface of the neck part 2 of the guitar, and a hard synthetic resin pressing piece 3 that extends rearward from one end of the pressing piece 3. The extending piece 4 made of synthetic resin is formed into a substantially inverted L-shape in cross section. Support pieces 5 are formed inside both ends of the pressing piece 3, and groove-shaped portions 6 are formed inside the extension piece 4.

One end of a fixed piece 7 made of hard synthetic resin is pivotally attached to the corner where the pressing piece 3 and the extending piece 4 form a right angle with a shaft 8 so as to be able to hold the neck part 2. An elastic material 9 is placed between the grooved portion 6 and the back surface of the fixed piece 7.
(For example, a coil spring or a leaf spring) is attached in a bent shape.

The fixing piece 7 is urged toward the pressing piece 3 by the elastic member 9, and the fixing piece 7 rotates from side to side around the shaft 8, so when the fixing piece 7 is pushed outward, the neck portion is released. I can accept it.

Further, a supporting piece 10 extending forward is formed inside the upper part of the fixing piece 7, and a presser part 11 is formed at the upper end of the fixing piece 7.

Support pieces 5 and 1 for the pressing piece 3 and the fixing piece 7, respectively.
0 has a shaft hole 12 on the opposite side, and a rotating part 13 equipped with a ball bearing is attached to the shaft hole 12.

Inside each of the pressing piece 3 and the extending piece 4, there is a rotating shaft 14 that rotates movably along the neck part 2 when attached to the neck part 2 between the rotating parts 12 of the respective supporting pieces 5 and 10. Attach to the shaft.

The rotating shaft 14 is made of a metal shaft 15 and is wound with a hard synthetic resin material 16 so as to have the same thickness as the extension length of the supporting piece 5, so that when it is fitted into the neck portion 2, it rotates and moves along the neck portion. can.

In the present invention with such a configuration, by holding the extension piece 4 and the fixing piece 7 with one hand and spreading the fixing piece 7 outward, it can be fitted into the neck part 2.
Once fitted into the neck part 2, when moving it to adjust the sound quality, hold the extension piece 4 and the fixed piece 7 with one hand and move the hand back and forth, so that the rotating shaft 14 of each piece 4, 7 can be rotated. Therefore, it can be easily moved along the neck part 2 to the appropriate sound quality range, compared to conventional capotasts where you have to remove them from the neck part with both hands each time you move the sound range.
In particular, the sound quality can be adjusted by simply moving it with one hand while it is still attached to the neck part 2.

Therefore, the present invention is not only easy to attach to the neck part 2 of the guitar by simply holding the extension piece 4 and the fixing piece 7 with one hand and expanding the fixing piece 7 outward, but also particularly, once the guitar is After it is fitted into the neck part 2, it can be moved with one hand to adjust the sound quality, so it does not require any effort and has the advantage that the range can be changed without stopping during the performance.

In addition, it is lightweight because it is made of hard synthetic resin instead of metal like conventional capotasts.
In addition, since the structure is simple, it is lightweight and has excellent productivity, making it suitable for mass production, so it is practical.
