Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a tuning mechanism in the necks of electric guitars and various other guitars.

(Prior art) Conventional guitars have a tenjin section at the end of the neck, and tuning is performed by the thread winding. There were problems such as unstable tuning due to the long distance, and the tuning operation was also troublesome.

(Technical Issues) Therefore, the present invention eliminates the conventional so-called tenjin part, performs tuning by advancing and retracting a piece with a fixed string end instead of a bobbin winding, and makes the tuning operation easier by improving the arrangement and shape of the tuning nut. The present invention provides a guitar tuning mechanism that is capable of obtaining good tuning results and improving sound quality.

(Technical means) The present invention that achieves the above purpose is at the tip of network 1,
A main body 5 is attached in which pieces 4 for fixing the ends 3 of each string 2 are arranged so as to be movable in advance and retreat, and advance/retreat adjustment shafts 6 with one end attached to each piece 4 are protruded from respective through holes 7 of the main body 5, and their tips are The threaded portion 8 is threaded with a tune nut 9, and each tune nut 9 has a different length.

(Function of the invention) In the invention, the end 3 of each string 2 is fixed to the bridge 4 arranged on the main body 5, so the tension can be adjusted by linear movement of the bridge.
There is no possibility of problems caused by conventional thread winding and thread tightening. The adjusting shaft 6 for advancing and retracting each piece 4 is protruded from the tip of the main body 5, and the lengths of the tune nuts 9 screwed into the threaded portion 8 at the tip are made different, so that even if the string spacing is close, each nut 9 can be adjusted. Since it is possible to tune the front and rear parts separately and clearly distinguish them, the operability can be improved. Also, the end 3 of the string 2
can be placed at the tip of the neck 1, so the distance between the nut at the end of the neck and the string fixing point can be shortened as much as possible.

(Embodiment) The illustrated embodiment relates to an electric guitar, and the part at the tip of the neck 1 where the conventional tenjin part was installed has become a base part 10 to which the main body 5 of the present tuning mechanism is tilted downward and attached.

The main body 5 is composed of a base 11 and a cover 12 having a generally L-shaped side surface and a front gate shape, which is attached to the upper part of the base 11, and a piece 4 for fixing the string 2 is fitted into an internal space 13 so as to be movable forward and backward. The end of each string 2 is fixed to the accommodation recess 16 of the bridge 4 through the slit 15 of the bridge 4 by a ball end holder 14, and the string end is secured to the pad 25 by a lock screw 17 screwed into the recess 16'. It may also be tightened and fixed through the screw (Fig. 3).
18 indicates a nut provided at the end of the net, but each piece 4
Since it is placed immediately after this nut 18, unnecessary vibration of the string 2 is eliminated.

Each piece 4 is connected to a screw shaft 6 for advancing and retracting adjustment which is screwed onto its tip and tightened with a set screw 19, and each screw shaft 6 projects from the through hole 7 to the tip of the main body. Seta Chunnut 9A, 9
B are screwed together alternately. The long nut 9A has an extension portion 20 approximately corresponding to the length of the short nut 9B,
They are formed slightly thicker than the short nuts 9B, and each has a knurl on its surface. Reference numeral 21 indicates an internal thread of the tune nuts 9A and 9B, 22 indicates a hole at an end thereof, 23 indicates an assembly nut of the main body 5, and 24 indicates a fret.

(Effect of the invention) Therefore, according to the invention, the tension can be adjusted without winding the string 2 by advancing and retracting the piece 4 with the string end fixed, so the tuning operation can be performed smoothly, and the string end can be fixed. Since the distance between the string and the nut can be significantly narrowed, and there is no need for an unnecessary winding part of the string, a stable tuning effect can be obtained. Therefore, it is very easy to operate, and since the mechanism is simplified, it is easy to manufacture and process, and it is also easy to install. Additionally, tremolo-type tailpieces conventionally required a complex and expensive fin inching mechanism, but the present invention eliminates the need for this, leading to cost reductions. Furthermore, since the conventional tenjin section can be eliminated, unnecessary vibrations are not generated, and deterioration in sound quality can be prevented.
