Description

[Detailed explanation of the idea] [Industrial application field]

The present invention is a Taishogoto tensioner that improves the rotation support part of the thread winding pin to the end of the resonator body, which adjusts the tension of the strings and adjusts the musical scale by winding the strings of the Taishogoto and rotating them. This relates to a string device.

[Conventional technology]

Conventionally, as shown in FIG. 2, the stringing device 2 of the Taishogoto 1 has metal (for example, brass) thread winding pins 4, 4... are arranged vertically so as to be rotatable in the horizontal direction, strings 5 are wound around each of the thread winding pins 4, and by rotating the pins 4, the tension of the strings 5 is adjusted to adjust the musical scale. In addition, at the rotary support part of the thread winding pin to the end of the resonator body, a fin plate is provided protruding parallel to the axis on the outer peripheral surface of the tube whose inner surface is formed into a tupular shape with an extremely small angle. Japanese Utility Model Publication No. 12773/1983 discloses a string rod that is driven into the base of a taishokoto and has a string rod having a conical portion having the same shape as the above-mentioned trumpet and fitted into the tube with a plastic tube interposed therebetween.

[Problem that the idea aims to solve]

By the way, in the above-mentioned conventional Taishogoto 1, since the thread winding pin 4 is directly rotatably installed on one end 3a of the resonator body 3, the rotation of the thread winding pin 4 causes the rotation support part (particularly the wooden part) to be damaged. ) became worn and loosened, making it impossible to adjust the strings adequately. In addition, in the string winding rod of the prior art Taishogoto disclosed in Utility Model Publication No. 45-12773,
A fin plate is protruded from the outer circumferential surface of a tube formed in the shape of a lapa in parallel with the axis, and this is driven into the base of the taishokoto.A string-wound rod having a conical part of the same shape as the lappa is inserted into the tube with a plastic tube. Since it is fitted with
The tube was so worn that it was not easy to replace it. The present invention has been made to solve the above problems.

[Means to solve the problem]

In order to achieve the above object, the present invention is to install a metal thread-winding pin horizontally rotatably at the end of the wooden resonance body, and to rotate the pin by winding a string around the thread-winding pin. In the Taishogoto, in which the tension of the strings can be adjusted by means of It is characterized in that it is fixed and a thread winding pin is inserted into this bushing.

[Effect]

Due to the above structure, the Taishogoto stringing device of the present invention has much better abrasion resistance of the bushings than that of wood, so even after many years of use, there is little wear and accurate tuning can be achieved. In addition, when the bushing becomes worn out, its function can be restored by replacing it, and the replacement work can be performed simply and easily.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In the Taishogoto 1 shown in FIG. 2, like the conventional one, the tuning device 2 has a thread winding pin 4 erected at one end 3a of the wooden resonance part 3.
The end of string 5 is wrapped around. As shown in FIG. 1, a bushing 6 made of rubber is interposed in the rotary support portion of the thread winding pin 4 to one end 3a of the resonance body. This button 6
is tightly fitted into a hole drilled in the vertical direction for one end 3a of the resonance body, and the thread winding pin 4
For the pin insertion hole 6a, the cylindrical part 4a of the pin 4 is inserted and the prismatic part 4b of the pin 4 can be rotated with appropriate wear resistance by rotating the prismatic part 4b by an appropriate means.
It has a flange 6b at the upper end. The bush 6 can be replaced as necessary.
In addition, the code|symbol 4c is a string insertion hole penetrated through the lower end of the square column part 4b of the thread winding pin 4. In the tuning device 2 having such a configuration, the string 5 has one end fixed to the other end (not shown) of the resonance body 3.
Insert the other end into the string insertion hole 4c of the thread winding pin 4,
The scale is adjusted by rotating the pin 4 in the horizontal direction via the prismatic portion 4b to adjust the tension of the string 5. At this time, the bushing 6 is made of rubber and has a high abrasion resistance, and the thread winding pin 4 is fixed at its rotational position to perform accurate tuning. In addition, if the pin insertion hole 6a of the bush 6 has worn out over many years of use and has become loose between it and the cylindrical part 4a of the pin 4, the tuning function can be improved by replacing the bush 6 with a new one. can be recovered. The bush 6 can be replaced simply and easily. The bush 6 is not limited to rubber, and may be made of a synthetic resin having properties similar to rubber, or a composite of rubber and synthetic resin.

[Effect of the idea]

As explained above, according to the Taishogoto stringing device of the present invention, the bush having a collar made of rubber or the like is fixed without the thread winding pin being rotatably installed directly on the end of the resonator body. Since the thread winding pin is fitted inside, there is less wear than when the thread winding pin is directly installed, and the string can be tightened without loosening. Furthermore, if the bushings become worn out, the Taishogoto can be used for a long time by replacing them. Furthermore, the bubutsu can be easily and easily replaced, and it can be easily attached to a conventional taishokoto with a little modification.

Claims (1)

[Claim for Utility Model Registration] A metal thread-winding pin is vertically rotatably installed at the end of the wooden resonator body, and by winding a string around this thread-winding pin and rotating the pin, the string can be turned. In a Taishogoto whose tension level can be adjusted, a bush having a flange made of rubber or the like is fixed to the rotary support part of the thread winding pin at the end of the resonator body, passing through the end of the resonator body up and down, This Taishogoto stringing device is characterized by a thread winding pin inserted into the bush.
