Description

[Detailed Description of the Invention] The present invention relates to a string fixing device in a tremolo mechanism of a stringed musical instrument.

This type of device is known from Utility Model Application No. 56-170488. However, since the strings are fixed by a string presser and the string presser is tightened by a screw, the tightening force of the screw acts indirectly on the strings, which causes frequent rocking during tremolo playing. There is a risk that it will gradually relax when use is applied, and there is no way to stop it once it occurs.

On the other hand, the bridge structure of Utility Model Application Publication No. 56-170488 proposes a structure in which the string presser is screwed near the end of the string in order to prevent the strings from loosening, but such a structure requires less space to install the string presser. is newly required, which causes the problem of increasing the size of the bridge base. Furthermore, since the strings are stopped using the string presser, there is a risk that the strings will meander and be stopped, and two screws are always required, making it extremely difficult to handle.

The object of the present invention is to provide a string fixing device which has the simplest structure and does not cause the string to slack at all due to the operation of the tremolo mechanism.

Examples will be described below with reference to the drawings. The string fixing device according to the present invention has a string 2 to be strung on a string instrument 1.
This is a string fixing device for a tremolo mechanism that fixes one end, and has a structure in which the same number of blocks 4 as the strings 2, which individually receive each string 2, are arranged in parallel on a tremolo mechanism main body 3 so that the position can be adjusted in the front and back direction. . The block 4 has a guide hole 6 passed through it vertically for passing the string 2 through it, and a support part 5 for receiving and supporting the string 2 passing through the guide hole 6 at the upper front end of the block. Reference numeral 5 includes a groove-shaped part 4a formed in a groove-like shape on the upper surface of the block for passing the string 2 from the upper front end toward the middle of the depth of the guide hole 6, and a peripheral wall part 4b surrounding the groove-shaped part 4a. , has an inclined part 4c cut out from a part of the front end of the peripheral wall part 4b so as to be flush with the bottom of the grooved part 4a, and has an inclined part adjacent to the string 2 passing through the grooved part 4a. A screw hole 4d is formed in the screw hole 4c, and the receiving support portion 5 is inserted between the head 7a of the set screw 7 screwed into the screw hole 4d and the groove-like portion 4a.
The strings 2 located at are fixed. Reference numeral 8 in the figure denotes a spring acting on each block 4, which is wound around a screw 9 that allows the position of each block 4 to be adjusted in the front and back direction, and the screw 9 is attached from the rear end of the tremolo mechanism main body 3. 10 is a spring acting on the main body 3, 11 is a tremolo mechanism lever, 12 is a block adjustment screw,
13 is a fixture at the other end of the string 2.

Since the present invention is constructed as described above, in order to attach the string 2, one end is passed through the lower end of the tremolo mechanism main body 3 and locked to the lower end of the guide hole 6.
From there, the other end can be wound around a peg through the groove-shaped portion 4a and the receiving and supporting portion 5, and rough tuning of the string can be performed at this stage. Next, the block 4 is moved back and forth to adjust the octave, and then the set screw 7 screwed into the screw hole 4d of the block 4 is tightened to tighten the string between its head 7a and the groove-like part 4a of the receiving support part 5. 2
Tighten the string, tune the string again using the peg, and tighten the fixture 13.
Finally, string 2 is fixed.

In the above work, each string 2 is fastened to the block 4 of the tremolo mechanism by a set screw 7 on the one hand, and is secured by a fixture 13 on the other hand, and since they are independent in the tuned state between them, the tremolo is controlled by the operating lever. Even if the strings are loosened or pulled by operating the mechanism, each string 2, which is tightened to the block receiving support part 5 by the head 7a of the set screw 7, will not sag, and the scale will remain as tuned. and there is no risk of modulation. In particular, as can be understood from Figures 2 and 4, by passing the string 2 to the right side of the set screw 7, the tension of the string 2 acts in the direction of tightening the set screw 7, thereby preventing the set screw 7 from loosening. can do.

The present invention is constructed as described above, and since it is not necessary to insert the string 2 into a small hole, the string 2 can be passed through very easily. , block string 2 4
It is easy to hang the string 2, and the string 2 is stable.Furthermore, with the set screw 7 attached to the inclined part 4c flush with the bottom of the groove 4a, the string 2 can be fixed very easily. It has the feature that the fixing condition can be visually confirmed by the tightening condition of the set screw 7, and the number of parts can be kept to a minimum, and at the same time, the shape of the block 4 does not change much and the base does not become large. Therefore, it is very easy to implement, has an excellent fixing effect for the string 2, has all the conventional bridge mechanisms, and can be handled in the same way as a conventional accessory.
