Abstract

A peg about which a violin or cello string is wound is provided with an internal mechanism for tensioning the string. The string tensioning function is performed by three components within the peg, a screw (6), a nut (5), and a pulley (2), as shown in Fig. 10. The peg has a fine adjustment function and features an extremely simple construction.

Description

Specification

"Title of Invention"

Fine adjustment beg

"Technical field"

The present invention relates to a violin, viola, cello, or contrapaths tag, and relates to a jig for easy tuning.

"Background technology"

Since conventional pegs are difficult to operate, tail pieces of musical instruments with azure stars for tuning are commercially available and used. In addition, because there are disadvantages with the adjuster, there have already been invented several kinds of pegs that can be easily fine-tuned to make the adjuster unnecessary. For example, there are Japanese Patent Application No. 105895 No. 105895 "Beg with Fine Adjustment Machine" and similar ₆ There are Japanese Patent Application No. 165794 Japanese Patent No. 165794 "Fine Adjustment Beg" .

"Disclosure of the invention"

Conventional pegs are difficult to operate. Also, take it to the tail piece of the instrument to solve it! The attached or built-in Asia Star has several disadvantages. For example, there is a drawback in that the tone of the Asian star is directly connected to the vibrating string, so the tone is metallic, and the tone is dark due to the heavy weight. At the mouth, it is generally not possible to operate the Asian star while playing the strings with a bow. In addition, existing pegs and pegs with built-in fine adjustment mechanisms that have already been invented will rub against the main body of the instrument when tuning. I suddenly loosened during the performance, and I had to worry that the precious old instruments could be damaged, especially because I had to push the peg into the hole in the peg box.

The present invention solves the above-mentioned drawbacks of the peg, the adjuster, or the invented begg with a built-in adjustment mechanism.

Describing the present invention, the part shown in FIG. 1 is one of the main parts of the present invention. The cylinder (/) in Fig. / Corresponds to the tapered part of the existing peg, and has a pulley (= 2) inside. The pulley (.2) is connected to the cylinder (/) by the shaft (3) as shown in Fig. = 2! ), And the pulley () can rotate around the axis (J). The cylinder (/) is provided with a round hole as shown in Fig. 3, and the inner surface of the round hole is locked as shown in Figs. () Is fixed.

Next, another main part of the present invention is shown in FIG. The grip in Figure ^! ) Hand (7) is the part corresponding to the handshake part of the existing peg. Then, a screw () is inserted into the center of the grip and the hand (7) and fixed. The nut () is screwed with the screw ().

Next, the description of FIG. Fig. 、 Is a view showing the state where the nut (ir) and screw (έ) shown in Fig. Are inserted into the round hole made in the cylinder (/) of the part shown in Fig. / It is. This one? The figure shows the whole invention.

The operation will be described. Fig. / Is a drawing that adds a string () to Fig. II. As shown in Figure / Figure, insert the string () into the hole on the side of the cylinder (factory). And fix it to the nut () via the pulley ().

Here, tuning with the existing peg means that the peg is rotated, the string is wound around the peg, and the string is drawn to the peg side. However, in the fine-adjustment peg according to the present invention, the cylinder (/) does not rotate at all during tuning, and only the grip], the hand (h) and the screw () are used. Rotate. Then, when the hand (7) is turned, the screw () is turned. When the screw () is turned, the position of the nut () screwed with the screw is changed to the / position. Move from the position shown in the figure to the position shown in Fig. / C2. In this case, as shown in Fig. //, the nut () moves in parallel without rotating due to the action of the stop]). The chord) is drawn into the cylinder (/), as shown in the comparison between Figs. The tuning operation is performed as described above.

In this way, it is possible to adjust the pitch by turning the hand D with a small amount of force.] A small amount of tuning can be done easily. Also, it is not necessary to push the cylinder (/) firmly into the instrument's egg box, and the instrument () needs to rotate when tuning, which may cause the instrument to wear. In addition, the structure is very thimble compared with the already invented peg with a built-in fine adjustment mechanism. The pulley (J) does not necessarily need to rotate. For example, as shown in Fig. / J, the lubricating belt (/

) Is provided to cover the block (). Referring to Fig. / J, the block (?) Is fixed to the cylinder (/), and the lubricating property to eliminate the friction between the string () and the block (?). Figure showing an embodiment with a belt (/)

Next, another embodiment will be described. Fig./4i is a drawing of the main part centered on the hand iJ hand B (/), and corresponds to Fig.4i. The end piece (/ /) in Fig. / Is fixed to the screw Β (/). The nut Β (/ 3) is fixed to the handshake Β (/). The screw Β (/ 2) and the nut Β (/ 3) are screwed. Then, Fig. 7 / Fig. / Fig.? The figures respectively correspond to FIG. 10 and FIG. I / FIG. 2 and are diagrams showing the operation. Fig./7 differs from Fig./Fig. In that the parts shown in Fig./Fig. Are different, and the rotation of Fig./Fig.] Is stopped (4 is the rotation in Fig./7!). It is the same as Fig. I except that it changes to.], Indicating that the strings () are fixed to the end pieces (/ /). So, grip! ) When the hand Β (/ ^) is turned, the nut Β (/ 3) is turned, and the screw Β (/) and the end piece (/ /) are translated. At this time, as shown in Fig./8, the end piece (/ /). ) Stop Β (/) U-turn due to the action of Β (/). No./? The figure shows the state in which the string () has been drawn into the cylinder (/) from the state shown in Fig. 7 in this way. In this way, the same effects as in the above-described embodiment can be obtained.
