Description

The present invention relates to a guitar, and more particularly to an acoustic guitar having a hollow body that resonates a string sound.

There are various types of guitars. Among them, as shown in FIG. 7, there are a hollow body 10 that resonates the sound of the string 70, a neck 20 that protrudes from the body 10, and a tip of the neck 20. There is a guitar 1 having a head 30 provided, and such a guitar 1 is called an acoustic guitar.

In such a conventional guitar 1, one end side of the string 70 is fixed to the bridge 40 of the body 10, and the other end side of the string 70 is wound around the tuning peg 31 of the head 30. Here, the fixing of the string 70 in the bridge 40 will be described in detail below.

As shown in FIG. 8, the bridge 40 is attached to the front side of the front plate 11 of the body 10. A reinforcing plate 41 is attached to the back side of the front plate 11 at a position corresponding to the bridge 40. Each of the bridge 40, the front plate 11, and the reinforcing plate 41 is provided with through holes 40a, 11a, 41a through which the strings 70 are inserted.

On the other hand, an end piece 71 having a ring shape, a ball shape, a bullet shape, or the like is usually attached to a terminal on one end side of the string 70, and the through holes 40 a, 11 a of the bridge 40, the front plate 11, and the reinforcing plate 41. 41a, the end piece 71 of the string 70 is inserted into the bridge 41, and the end piece 71 is locked to the back side of the reinforcing plate 41. Fixed.

8 shows an example in which the through-holes 40a and 41a of the bridge 40 and the reinforcing plate 41 are provided with the relief grooves of the string 70, but when the pin 60 provided with the escape grooves of the string 70 is used, It is not necessary to provide such an escape groove.

In the conventional guitar in which one end of the string is fixed to the bridge with the above-described structure, when the string is stretched, stress is applied to the top plate of the body due to the tension of the string. Specifically, the end piece of the string is actually locked to the reinforcing plate, the reinforcing plate is pulled by the tension of the string (see arrow A in FIG. 6), and there is a stress that pushes the front plate from the back side by the reinforcing plate. Join.

Therefore, in the conventional guitar, when the string is stretched, the front plate may partially swell. In particular, since the stress that pushes up the front plate is locally applied around the through hole of the front plate, deformation is likely to occur around the through hole of the front plate. Here, the shape of the body of the guitar has been set by the producer with great ingenuity in order to produce a good sound, and even if the shape of the body is slightly deformed, the tone intended by the manufacturer cannot be produced. It may end up. Therefore, it is not desirable that the body is deformed by stretching the strings.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a guitar whose body is not easily deformed even when a string is stretched.

The main means taken by the present invention to solve the above problems are as follows:
“With a hollow body that resonates the sound,
A guitar provided with a string end fixture that is disposed on the back side of the front plate of the body and fixes the end of the string,
The string end fixture includes a locking portion for locking the end of the string,
The guitar is characterized in that the locking portion is disposed at a position separated from the back surface of the front plate of the body "
It is.

In the guitar configured as described above, the locking portion that locks the end of the string of the string end fixture, i.e., the portion that substantially fixes the end of the string is disposed at a position separated from the back surface of the front plate of the body. Therefore, even if a stress due to the tension of the string is applied to the locking portion, this stress is not locally applied to the top plate of the body. That is, when the string end fixture is directly attached to the front plate, the stress from the locking portion is distributed over the entire surface where the string end fixture contacts the front plate, and the string end fixture is interposed. In the case of being indirectly attached to the front plate via an object, the inclusions are dispersed over the entire surface contacting the front plate. Therefore, unlike the conventional guitar, local stress is not applied around the through hole of the front plate, and the body is difficult to be deformed even if a string is stretched.

In the means described above,
“A bracing provided on the back side of the front plate to reinforce the front plate,
The string end fixture is attached to the bracing "
Is preferable.

In the guitar of the above configuration, when the string is stretched, the string end fixing tool is pulled, but the string end fixing tool is attached to the bracing, and this bracing reinforces the front plate. . Therefore, even if the string end fixture is pulled by the string, the tensile stress is not locally applied to the front plate, but is distributed through the entire bracing and applied to the front plate. Therefore, the body is a guitar that is more difficult to deform.

In the means described above,
"The string end fixture is
A pair of legs fixed to the front plate;
It has an insertion part for inserting the end of the string, and has a construction part constructed between the pair of legs,
The locking portion is constituted by a slit provided in the leg portion so as to communicate with the insertion portion.
Is preferable.

The guitar having the above-described configuration specifically limits the form of the string end fixture as a form having a pair of leg portions and an erection portion constructed on each leg portion. In other words, the form of the string end fixture is a U-shaped cross section. Therefore, the string end fixing tool disposed at a position where the locking portion is separated can be realized with a simple structure.

In the means described above,
"The string end fixture is
A plurality of ribs standing on the back surface of the front plate and allowing the end of the string to pass between each;
It has an erection plate erected on each rib,
The locking portion is constituted by a slit provided in the installation plate "
Is preferable.

The guitar having the above-described configuration specifically limits the form of the string end fixture as a form having a plurality of ribs and a construction plate constructed on each rib. In such a string end fixture, a resonance box is formed by the rib and the erection plate. Therefore, in the guitar provided with such a string end fixture, the guitar has a small resonance box inside the body, and the tone to be resonated in the body can be improved to a better tone.

As described above, according to the present invention, it is possible to provide a guitar whose body is hardly deformed even when a string is stretched.

It is a front view which shows an example of the guitar which concerns on this invention. It is a longitudinal cross-sectional view of the bridge part of the guitar shown in FIG. It is a principal part longitudinal cross-sectional view which shows another example of a string end fixture. It is a figure which shows another example of a string end fixing tool, and is the rear view seen from the back side of the front board of a body. It is a figure which shows the other example of a string end fixing tool, and is the perspective view seen from the back side of the front board of a body. It is a figure which shows the other example of a string end fixing tool, and is the perspective view seen from the back side of the front board of a body. It is a front view which shows the conventional guitar. It is a longitudinal cross-sectional view of the bridge part of the guitar shown in FIG.

Hereinafter, an example of an embodiment of a guitar according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of a guitar 100 according to the present invention.

This guitar 100 has a hollow body 10 that resonates the sound of a string 70, a neck 20 protruding from the body 10, and a head 30 provided at the tip of the neck 20, and one end side of the string 70 is attached to the body. 10 is fixed to the bridge 40, and the other end of the string 70 is wound around the tuning peg 31 of the head 30. The external appearance is the same as that of the conventional guitar 1. In the drawings, the same reference numerals are given to the same components as those of the conventional guitar 1.

In the guitar 100 of this example, a bracing 12 that reinforces the front plate 11 is affixed to the back side of the front plate 11 of the body 10 in the same manner as a general conventional guitar 1. In this example, the X-shaped bracing 12 is shown, but the form of the bracing 12 is not limited to this, and can be appropriately set to an H shape, a lattice shape, or the like.

The guitar 100 of this example is different from the conventional guitar 1 in the structure of fixing the string terminal at the bridge 40. The structure of fixing the string terminal will be described below.

As shown in FIG. 2, the front plate 11 of the body 10 is provided with a bridge 40 on the front side and a string end fixture 42 on the back side. Here, the bridge 40 disposed on the front side of the front plate 11 is disposed so that both end portions thereof overlap the bracing 12 (see FIG. 1), and is attached to the surface of the front plate 11. The string end fixture 42 is formed in a plate shape having substantially the same outer shape as the bridge 40, and is attached to the bracing 12 on the back side of the front plate 11. More specifically, both ends of the string end fixture 42 are affixed to the bracing 12.

When the end of the string 70 is fixed by such a string end fixture 42, the end piece 71 of the string 70 is inserted into each of the through holes 40 a, 11 a, 42 a of the bridge 40, the front plate 11, and the string end fixture 42. The end piece 71 of the string 70 can be fixed to the string end fixture 42 by attaching the pin 60 as in the conventional guitar 1.

Here, the end piece 71 of the string 70 is locked around the through hole 42 a by the tip of the pin 60 protruding from the through hole 42 a of the string end fixture 42 and is fixed to the string end fixture 42. The through hole 42 a of the string end fixture 42 can be regarded as a locking portion that locks the end of the string 70. In the guitar 100 of the present example, the string end fixture 42 is disposed in a state of floating from the back surface of the front plate 11 via the bracing 12, and the locking portion (through hole 42a) is provided on the front plate 11. It is arrange | positioned in the position spaced apart from the back surface. Therefore, even if tension of the string 70 is applied to the through hole 42a (locking portion) of the string end fixture 42, local stress is not applied around the through hole 11a of the front plate 11, and the body 10 is deformed. It is a difficult guitar.

In the guitar 100 of this example, the string end fixture 42 is not directly attached to the back surface of the front plate 11, and the pin 60 is attached to the brace 12 as compared with the conventional guitar 1. The mounting hole is deep. Therefore, when the pin 60 of the conventional guitar 1 is too short, the pin 60 is mounted from the back side of the front plate 11, that is, the string end fixture 42 side, as shown by a two-dot chain line in FIG. The end piece 71 of the string 70 may be locked to the through hole 42a of the string end fixture 42 by the head of the string.

In addition, as shown in FIG. 3, a slit 42b is provided on the neck 20 side in the through hole 42a of the string end fixture 42, or although not shown, the string 70 is located near the through hole 42a of the string end fixture 42. A hooking portion for hooking the end piece 71 is provided, and the slit 42b and the hooking portion are used as locking portions so that the end piece 71 of the string 70 can be locked to the string end fixing tool 42 by this locking portion. May be. By doing so, the end of the string 70 can be fixed to the bridge 40 without using the pin 60.

By the way, when the string 70 is stretched on the guitar 100, the bridge 40 is sandwiched between the string 70 and the front plate 11. Therefore, although it is not necessary to firmly fix the bridge 40 to the front plate 11, in the conventional guitar 1, since the pin 60 must be mounted on the bridge 40, the bridge 40 is firmly fixed to the front plate 11. Therefore, it was forced to stick on the front plate 11.

On the other hand, if the pin 60 is unnecessary as described above, it is not necessary to firmly fix the bridge 40 to the front plate 11 and the bridge 40 can be attached to and detached from the front plate 11. it can. If the bridge 40 can be attached to and detached from the front plate 11, the guitar 100 can be easily exchanged for another bridge 40 having a different shape, pattern, material, etc. according to the user's preference.

When the bridge 40 is configured to be detachable, the bridge 40 can be easily replaced if the bridge 40 can be positioned with respect to the front plate 11 using a dowel or the like.

Further, the through hole 40a of the bridge 40 is indispensable because the end of the string 70 must be inserted. However, if the guitar 100 does not require the pin 60 to be attached to the through hole 40a of the bridge 40, the through hole Various decorative parts can be attached to the bridge 40 using the 40a, and the decoration of the bridge 40 can be enjoyed.

FIG. 4 shows another example of the string end fixture 42. In this example, a string end fixture 42 is attached to the intersection of the bracing 12.

When the bracing 12 has an intersection that intersects in an X-shape or V-shape, the intersection is a portion that reinforces the top plate 11 most firmly. The intersection is the most difficult part to deform. Therefore, by attaching the string end fixture 42 at the intersection of the bracing 12, the guitar 10 in which the body 10 is less likely to be deformed can be obtained.

In this example, the string end fixture 42 is attached to the intersection of the bracing 12 via the connecting plate 43. However, the string end fixture 42 is overlapped with the intersection so that the string end fixture 42 overlaps the intersection. The string end fixture 42 may be directly attached.

Further, when the string end fixture 42 is unstable due to being separated from the brace 12 or the front plate 11, as shown by a two-dot chain line in FIG. Appropriate support bases 44 and 45 such as the support base 44 and the support base 45 between the bracing 12 and the string end fixture 42 may be interposed.

Here, in the aspect in which the support base 44 is provided between the front plate 11 and the string end fixture 42, stress due to the tension of the string 70 is applied from the string end fixture 42 to the front plate 11. Since the tool 42 is also attached to the brace 12, all of the stress is not applied to the front plate 11 and is distributed to the brace 12. Therefore, even in such an aspect, the guitar 100 in which the body 10 is difficult to deform can be obtained.

FIG. 5 shows another example of the string end fixture 80. In this example, the string end fixture 80 is attached to the back surface of the front plate 11 so as not to interfere with the bracing 12. However, the present invention is not limited to this. It may be attached to the racing 12.

The string end fixture 80 includes a pair of leg portions 81 and an erection portion 82 installed between the legs 81, and is formed in a U-shaped cross section by a metal plate. The installation portion 82 is provided with an insertion portion 83 that is large enough to allow the end piece 71 of the string 70 to be inserted therein. The leg portion 81 on the neck 20 side is provided with a slit 84 that communicates with the insertion portion 83. It has been. Here, the slit 84 constitutes a locking portion for locking the end piece 71 of the end of the string 70, and has a width dimension in which the end piece 71 cannot be inserted. Therefore, the end piece 71 of the string 70 inserted through the insertion portion 83 is locked to the slit 84 (see arrow B), so that the end of the string 70 can be fixed to the string end fixture 80.

When the end of the string 70 is fixed by such a string end fixture 80, even if the string end fixture 80 is pulled by the tension of the string 70, the slit 84 which is a locking portion for locking the end piece 71 is formed on the front plate. Therefore, the tensile stress is distributed over the entire leg portion 81 of the string end fixture 80 and applied to the front plate 11. Therefore, no stress is locally applied around the through hole 11a of the front plate 11, and the body 10 is not easily deformed.

FIG. 6 shows another example of the string end fixture 90. In addition, this string end fixing tool 90 may be attached to the back surface of the front plate 11 or may be attached to the bracing 12 so as not to interfere with the bracing 12, similarly to the above-described string end fixing tool 80. Is.

The string end fixture 90 includes a bottom plate 91 attached to the back surface of the front plate 11, a plurality of ribs 92 erected from the bottom plate 91, and an erection plate 93 erected on the upper surface of each rib 92. . Here, the ribs 92 are erected in the extending direction of the string 70, and the plurality of ribs 92 are arranged side by side so that an insertion space for the string 70 is formed between the ribs 92. The installation plate 93 is provided with a slit 94 constituting a locking portion for locking the end piece 71 of the end of the string 70, and the end piece 71 of the string 70 inserted between the ribs 92 is slit 94. The end of the string 70 can be fixed to the string end fixture 90 (see arrow c).

In this example, the rib 92 is erected from the back surface of the top plate 11 through the bottom plate 91 in which the insertion hole 91a of the string 70 is formed, but the bottom plate 91 is omitted and the top plate 11 is omitted. The rib 92 may be erected directly on the back surface of the plate.

Further, in this example, the erection plate 93 is provided with a top plate 93a covering the upper portion of the rib 92 on the neck 20 side, and a slit 94 is provided on the side opposite to the neck 20 side, and is attached to the upper surface of the top plate 93a. Although it is comprised by the slit plate 93b, not only this but the construction board 93 may be formed by the single member which has the slit 94 which comprises a latching | locking part.

When the end of the string 70 is fixed by such a string end fixing tool 90, even if the string end fixing tool 90 is pulled by the tension of the string 70, the slit 94 which is a locking portion for locking the end piece 71 is formed on the front plate. Therefore, the tensile stress is distributed over the ribs 92 of the chord end fixture 90 and further distributed over the bottom plate 91 and applied to the front plate 11. Therefore, no stress is locally applied around the through hole 11a of the front plate 11, and the body 10 is not easily deformed.

Further, a box-shaped space is formed by a pair of opposing ribs 92 and a construction plate 93 covering the upper portion thereof corresponding to each of the plurality of strings 70, and this box-shaped space becomes a resonance box. Therefore, in the body 10 that resonates the sound of the string 70, the sound of the string 70 can be further resonated by the individual resonance boxes, and the tone of the guitar 100 can be improved.
