Description

[Detailed description of the invention] This invention relates to a tremolo tailpiece for a guitar.

A device shown in FIG. 1 is used as a conventional tremolo tailpiece. In this type of tremolo tailpiece, a string holder 1 is screwed directly onto a guitar body 2 in a swingable manner, and the bottom of the string holder 1 protrudes downward and is inserted into a vertical through hole 3 drilled in this part. The string ends are held, and the strings 7 are passed through vertical holes in pieces 5 arranged in parallel at the top of the string holder 1 and stretched. Therefore, when installing the string 7, remove the back cover of the body 2 and insert the string 7 into the through hole 3 from the back side.
Moreover, due to its structure, the distance from the string end 7a of the string to the string support location of the bridge 5 becomes long when it is installed, which causes the problem that the tuning state of the string 7 is likely to change. Furthermore, since the bridge 5 is directly screwed into the string tension adjustment screw 8, there is a problem in that the front part of the bridge 5 cannot be smoothly moved up and down by the string height adjustment screw 9.

This idea was made to solve the above problems, and it makes it easy to change the strings, as well as smoothly adjust the string tension and string height. The purpose of the present invention is to provide a tremolo tailpiece for a guitar that does not easily cause distortion.

Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 2 shows a plan view of the tremolo tailpiece, and FIG. 3 shows a front view thereof. Reference numeral 10 denotes a base fixed to fit into a hole provided in a body plate 15 of the guitar, and a string holder 11 is mounted on the upper part of the base 10.
is rotatably supported within a predetermined range by shafts 14a and 14b perpendicular to the string 18. On the rear part of the string holder 11 is a lever 17 for operating the tremolo.
are screwed together, and the front lower part of the string holder 11 is connected to the base 1.
It is urged upward by compression coil springs 26a and 26b housed in the first spring chambers 12a and 12b. At the upper front part of the string holder 11, a 6 is provided that passes through the string 18 and holds the string end 18a.
The book through-holes 19 are arranged horizontally in one row. Reference numeral 22 indicates six pieces arranged in parallel at the upper center of the string holder 11, as shown in FIGS. 5 and 6.
A groove 27 is provided in the bottom in the longitudinal direction, and further,
A vertical through hole 23 communicating with this groove 27 is bored in the center. 28 is a rotation shaft provided at the rear of the piece 22, and the piece 2 supporting this rotation shaft 28
The rear end of 2 is partially cut out, and this cutout 29 communicates with the groove 27, and the string tension adjustment screw 25, which is screwed perpendicularly to the rotating shaft 28, is connected to the rotating shaft 28 within a certain range. It is configured so that it can rotate freely.
The head of this string tension adjustment screw 25 is passed through a hole bored in the rear end portion 20 of the string holder 11 and held, and the bridge 22 is moved by the screw 25 to adjust the string tension. Reference numeral 24 denotes two string height adjustment screws that penetrate through the front part of the bridge 22 and are screwed together. By screwing these screws 24 downward, the length of the projection from below is increased, and the front part of the bridge 22 can be adjusted. It acts to raise the height of the string 18. 21a, 21b are threaded spring seats 16 of compression coil springs 26a, 26b;
A and 16b are square pins for adjusting spring pressure.

In the tremolo tailpiece configured as described above, when stringing the string, first insert the string 18 inward through the through hole 19 at the front of the string holder, and then insert the string 18 into the string holder.
After inserting the vertical through hole 23 upward through the groove 27 at the bottom of the string 18, the tip of the string 18 is pulled in the direction of the neck. At this time, the piece 22 can easily flip upwards using the rotating shaft 28 as a fulcrum.
The string can be easily passed through the through hole 23 by standing the bridge 22 upright. The string height is adjusted by the screw 24, and the movement of the screw 24 causes the bridge 22 to smoothly rotate about the rotation shaft 28, so that the height adjustment is performed smoothly.
Furthermore, since the distance from the string end 18a to the string support portion of the bridge 22 is short, there is little change in string tension after tuning. In addition, since the string tension adjustment screw 25 is screwed onto the rotating shaft 28 of the bridge 22, no force is applied to the screw 25 in the bending direction, making it easy to adjust the string tension and prevent tension changes. few. The tremolo operation is
The string holder 11 is moved by the lever 17 to the shafts 4a, 4.
The operating force is adjusted by rotating the spring pressure adjusting square pin to adjust the biasing force of the compression coil springs 26a and 26b.

As described above, according to the tremolo tailpiece of this invention, since the bridge can rotate about the rotation axis, strings can be easily attached and string tension can be adjusted smoothly. In addition, because the length from the string end to the bridge is short, there is little change in string tension after tuning.
This has the effect of making the sound less distorted.
