Description

The present invention relates to a bolt and a collar for fixing a tail piece, which is a frame for fixing a string end, to a guitar body.

The tail piece for a guitar is a frame that fixes a string end as shown in FIG. The tail piece, which is the frame body, has an end portion 9 on an engaging portion 21 provided on an upper portion of a lifting bolt screwed to a female screw anchor 11 embedded in the guitar body 12 shown in the upper part of FIG. Is formed so as to be locked.
A notch 10 is formed at the end 9 of the tailpiece. The notch 10 opens in the direction of the guitar head, which is the downward direction of FIG. 6. The lifting bolt is inserted into the notch 10, and the tailpiece notch The portion 10 is made to be locked by the locking portion 21.
For this purpose, the locking portion 12 is provided with a pair of flanges 20 and 22 spaced apart from each other in the vertical direction, and the peripheral portion of the notch 10 of the tail piece is inserted between the flanges 20 and 22. It is like.
When such a tail piece is extended as shown in FIG. 7, the tail piece is pulled toward the head side, which is the left side direction of FIG. 7, by the tension of the string. 9 is locked to the lifting bolt, and by rotating the lifting bolt, the male screw portion 23 of the lifting bolt can be lifted and lowered within the female screw anchor 11 embedded in the guitar body 12. Thus, the end 9 of the tail piece is moved up and down in this way to adjust the string height.
Japanese Patent Laid-Open No. 03-116095

Since the conventional lifting bolt described above adjusts the height of the tail piece end 9 after the string is extended, it is not a structure that is fixed to the tail piece as shown in FIG. Since the end portion 9 of the tailpiece is locked only by the string tension to the locking portion 21 between the upper and lower flanges 20 and 22, the tailpiece and the upper bolt 20 of the lifting bolt and the tailpiece end portion 9 are 25, rattling occurs between the lower flange 24 and the tail piece end 9.
In addition, as shown in FIG. 7, the lifting bolt is not in a state where the male screw portion 23 is screwed into the female screw anchor 11 embedded in the guitar body 12 as shown in FIG. Further, rattling also occurs in the space 27 between the male screw portion 23 and the female screw anchor 11 of the lifting bolt.
The guitar body which is very important for the guitar due to the rattling between the tailpiece 24 and the lifting bolt 24 shown in FIG. 7 and the rattling between the male screw portion 23 of the lifting bolt and the female screw anchor 11 as shown in FIG. There is a problem that the transmission of string vibrations to the pickup 14 which is a microphone of the guitar is impaired due to the reduced transmission of the string vibrations to the guitar 12.
Further, in the conventional lifting bolt, as shown in FIG. 7, the tailpiece is locked to the lifting bolt only by the string tension. Therefore, there is a risk that the tailpiece falls when the string is replaced when the string tension is lost. It is also the cause of damage to 12.

  Bolts with presser flanges formed on the top side that hold both ends of the tailpiece, which is a frame to fix the string end of the guitar, from the top side in the direction of the guitar body, and insertion holes for inserting the bolts are formed. It has a collar that forms a receiving flange that supports it from the bottom side, sandwiches both ends of the tail piece with the bolt and collar, and screwes the male screw part of the bolt into the female screw anchor embedded in the guitar body. Fasten the tailpiece to the guitar body by tightening.

As described above, by using the bolt and collar of the fixing device of the present invention, as shown in FIG. 4, a high pressure bonding property is generated between the presser flange 2 and the female screw anchor 11 at the upper part of the bolt. 15 between the presser flange 2 and both ends 9 of the tail piece, 18 between both ends 9 of the tail piece and the receiving flange 6 at the top of the collar, and no looseness between the bolt male screw portion 5 and the female screw anchor 11. The transmission of vibration has been greatly improved, and amazing effects have been achieved in terms of sound expansion, sound pressure, and sound quality. In addition, fixing the tail piece to the female screw anchor 11 as described above means fixing to the guitar body 12 in which the female screw anchor 11 is embedded, and the tail piece falls when the string is exchanged so that the string tension is lost. And the danger of damage to the guitar body 12 due to falling tailpieces has been eliminated.

  FIG. 1 is a perspective view of the embodiment, FIG. 2 is a perspective view of a bolt of the fixing device of the present invention, and FIG. 3 is a perspective view of a collar of the fixing device of the present invention. is there.

The bolt of the fixing device of the present invention is a bolt for fixing the end portion 9 of the tail piece to the guitar body 12 from the upper surface. As shown in FIG. 2, the upper part forms a presser flange 2 that presses the upper surface of the tail piece end 9 toward the guitar body 12, and its shape is cylindrical so that the tailpiece end 9 is not scratched by rotation. It has become. The upper surface is formed with a minus groove 1 in which a bolt can be rotated by a minus screwdriver, and is screwed and tightened to a female screw anchor 11 embedded in the guitar body 12 shown in FIG. I can do it. Under the presser flange 2, a locking portion 3 is formed in a cylindrical shape to which a notch portion 10 in the end portion 9 of the tailpiece is locked. A backlash prevention portion 4 is formed between the locking portion 3 and the male screw portion 5 so as to be closely attached to the inside of the insertion hole so that no rattling occurs between the bolt and the collar insertion hole 8 shown in FIG. Has been. The lowermost part of the bolt is composed of a male screw portion 5 for screwing into a female screw anchor 11 embedded in the guitar body 12.

As shown in FIG. 3, the color of the fixing device of the present invention is a tube-shaped movable flange that supports the tail piece end 9 on the guitar body side, and a receiving flange 6 that supports the tail piece end 9 from the lower surface side is provided on the upper surface. Is formed. The receiving flange 6 is formed with the same diameter as the holding flange 2 of the bolt. A sleeve portion 7 that adjusts the height of the tail piece 9 according to the length thereof is formed at the lower portion, and the height of the tail piece can be adjusted in a stable state. An insertion hole 8 through which a bolt is inserted passes through the center of the vertical axis, and the bolt is inserted into the insertion hole 8 for execution.

The bolt is inserted into the insertion hole 8 of the collar, and the tail piece end 9 is disposed between the lower side of the holding flange 2 of the bolt and the upper side of the receiving flange 6 of the collar. 5 is screwed into the female screw anchor 11, and a screwdriver is inserted into the minus groove 1 at the top of the bolt and rotated in the tightening direction, whereby the bolt holding flange 2 presses the upper surface of the end 9 of the tailpiece, and the female screw anchor together with the collar. Tighten to 11 and fix. Since the female screw anchor 11 is embedded in the guitar body, that is, the tailpiece is fixed to the guitar body 12.
