Description

[Detailed Description of the Invention] The present invention relates to a device for finely adjusting the tuning of a string instrument.

Tuning of electric guitars is mainly done by adjusting the tension of the strings in the Tenjin section, and it is possible to lock the guitar in the tuned state using a lock mechanism, but since tuning errors occur during performance, this has to be corrected from time to time. There is a need to. However, most of the conventional ones have the inconvenience that they cannot be adjusted without releasing the lock, and although there are some that allow fine adjustment, they are complicated to install and require advanced machining.

The present invention solves the above problem, and its purpose is to provide a leaf spring connected to the lock part of the string that comes into contact with and separates from the tuned string, and to operate the spring to change and finely adjust the tension of the string. An object of the present invention is to provide a fine tuning device for a stringed musical instrument.

That is, in the present invention, a string lock main body 5 having a support plate surface 4 for holding down a string 3 is fixed to the tenjin section 2 of a string instrument 1.
A leaf spring 6 that can be moved into and out of contact with the string 3 is attached to the support plate surface 4, and a fine adjustment screw 8 that changes the supporting position of the string 3 in contact with the movable end 7 of the leaf spring 6 is screwed into the main body 5. This is a fine tuning device for string instruments. The illustrated embodiment shows a fine tuning device for an electric guitar 1, which is a string instrument, and a plate spring 6 that can be brought into contact with and separated from a string 3 is attached to a string lock body 5, and a string lock top 13 is attached to a string lock body 5 using a string lock screw 9. It is installed between. The leaf spring 6 has movable ends 7, 7 which are divided into two parts so as to hold two strings 3 at a time, and the screw 9 is passed through the through hole 11 in the middle of the movable ends 7, 7, and the rear end locking piece 6 ' is positioned by being locked to the rear end of the main body support plate 12, and the string 3 is locked to the support plate surface 4 on the lower surface of the support plate 12 by tightening the screw 9 and using the string lock piece 13 screwed into the lower end of the screw 9. It is fixed by doing this. Therefore, three leaf springs 6 are used for the six strings 3 and are arranged in a horizontal row. The movable tip piece 7 is arranged in a row on the front edge of the string lock body 5, and a fine adjustment screw 8 is screwed into the internal thread 14, so that the tension on the string 3 can be changed by bringing the screw end into contact with it from above. The support plate surface 4 and top 13
Both have protruding surfaces and face each other to lock the string 3. In each figure, 15 is the support plate 12 of the lock screw 9.
16 is a female screw provided in top 13, 17 is a space where top 13 is placed, 18 is a support between spaces 17, 19 is a screw hole provided in mounting base 20, 21 is a top Show each piece.

Since the present invention has the configuration described above, the movable end 7 of the leaf spring 6 is brought into contact with the string 3 tuned by the string lock body 5, and the tension of the string 3 is slightly changed by operating the fine adjustment screw 8. Can perform articulation. Therefore, according to the present invention, sufficient adjustment can be made even after the tuning is completed and the tune is locked, and furthermore, the operation is simple and the tuning is reliable.
