Description

[Detailed Description of the Invention] The present invention relates to a string locking mechanism for a stringed instrument, and particularly to a string locking mechanism for a stringed instrument on the body side of the stringed instrument.

Conventionally, most string locking mechanisms for stringed instruments, such as the tailpiece attached to the body of a guitar, are installed approximately parallel to the bridge that supports the strings, and each string is connected to the string. The stop position is usually set at the same height relative to the body surface.

However, in this prior art, each end of a plurality of strings of different thicknesses is bent and supported at exactly the same angle on the bridge, so thicker strings have a larger support area than thinner strings. The elongation of the string becomes large, and the thicker the string, the greater the internal stress in the vicinity of the supporting part.

For this reason, the tension near the bridge of the string applied to the vibrating part becomes relatively strong, and the rigid force component of the string itself becomes large, suppressing the vibration of the string, and the vibration energy is transferred to the bridge and the tailpiece. easy to escape through,
Therefore, it was not possible to obtain string vibration sustain and honest string vibration suitable for the difference in thickness of each string.

As a means to solve these drawbacks, a tailpiece equipped with the martial arts content shown in FIGS. 1 and 2 has already been published.

issue).

This Utility Application No. 52-061786, Utility Publication No. 55-246
As shown in FIG. 2, the thing described in No. 2 is such that the locking angle α of each string 1 to 6 in the tailpiece portion with respect to the horizontal plane gradually increases from the 6th string to the 1st string. The tail piece 7 is installed with the tail piece 7 inclined by β degrees with respect to the bridge 8.

However, when the tail piece 7 is arranged in this way,
The body 9 part that also functions as a diaphragm is the tail piece 7
This results in the disadvantage that the bass vibrations characteristic of guitars are partially inhibited.

Furthermore, the locking angle α of each string is immediately determined as a whole once the tailpiece 7 is installed and fixed, and therefore the locking angle α of a specific string can be changed in advance as necessary. However, it is inconvenient that it is not possible to satisfy performance demands such as wanting to dampen only the vibration of the string at an early stage or keep only the string vibrating for a relatively long period of time depending on the content of the music to be played. there were.

The present invention improves the drawbacks of the above conventional technique, and allows the locking angle of the string attached to the tailpiece to be easily changed.
As a result, it is possible to obtain string vibration sustain and honest string vibration suitable for the difference in thickness without interfering with vibrations in the bass region in particular, and to quickly adjust the damping time of string vibration as necessary. The objective is to provide a string locking mechanism that can be adjusted.

The present invention provides a plurality of locking through holes for each string, and at the same time arranges a plurality of locking through holes corresponding to each string in a direction substantially perpendicular to the guitar body, and furthermore, at least one A guide through groove is provided to connect a plurality of locking through holes corresponding to each string, thereby achieving the above object.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

Here, the same reference numerals are used for the same components as in the conventional example described above.

In FIG. 3, the bridge 8 is fixedly mounted on the guitar body 9 (see FIG. 4).

) A tail piece 10 is fixedly mounted substantially parallel to the main body.

This tailpiece 10 has six strings 1.2 degrees...
6, three locking through holes (hereinafter simply referred to as "through holes") are provided for each string.

) 12 are formed, and an inverted E-shaped guide through groove 13 connecting the three through holes 12 of the octopus is formed.

As shown in FIG. 4, each of the through holes 12 is parallel to the guitar body 9 and is arranged at a distance of 1, 2°, 6 strings in plan view.
are formed along each of the

For example, three through holes 1 for locking the fifth string 5 are provided.
2 are formed in a line in the vertical direction of the figure at predetermined intervals, respectively, as shown in FIG.

Also, each string 1, 2. ..., 6 is configured to be inserted into one of the three through holes 12 and locked by a locking member 14 provided at the end, as shown in FIG. 3, for example. has been done.

On the other hand, each of the guide through grooves 13 consists of a lateral groove 15 extending from each through hole 12 to the right in FIG. 3, and a vertical groove 16 that commonly connects the ends of the lateral groove 15.

Other strings, i.e. 1st to 4th and 6th strings 1°2,
..., 4, 6, and the through holes 12 and the guide through grooves 13 are formed in exactly the same way.

Other components except for the above tail beef 10 are:
It is formed exactly the same as the conventional one.

When changing the locking position of each string based on the above configuration, for example, when changing the locking position of the fifth string 5 from bottom to top as shown in FIG. 4, loosen the tension of the string 5. , the end of the string 5 is inserted into the horizontal groove 15 and the vertical groove 16 of the guide through groove 13.
This is done by moving the string 5 to the upper through hole 12 through the string 5 and then tensioning the string 5.

When the locking position changes from bottom to top, string 5
The locking angle α becomes smaller stepwise.

As the locking angle α becomes smaller, the internal stress of the string 5 near the support part on the bridge 8 becomes smaller, and therefore the tension of the string 5 near the bridge 8 in the vibrating part becomes relatively weaker, and the string vibration is reduced. It lasts for a relatively long time, resulting in smooth and honest string vibrations.

Furthermore, as the locking angle α becomes smaller, the contact area between the bridge 8 and the string 5 decreases, thereby further supporting the continuation of the string vibration.

As described above, according to this embodiment, the six strings 1.2.
. . . 6, when installing and locking the string, the locking angle of each string of the tailpiece 10 portion can be arbitrarily set individually in three stages, and the locking position can be quickly changed. I can do it.

For example, the locking angle α of the first string 1 and the second string 2 is set to a large value, and the other strings 3, 4 are connected at the same time. It is possible to set the locking angle α of the 2nd string 2 to a small value depending on the content of the song played, and to set the locking angle α of the 2nd string 2 to a small value, and to set the locking angle α of the 2nd string 2 to a small value. 4. ..., it is also possible to set the locking angle α of 6 to be relatively small.

Also, when playing multiple songs continuously, each string 1, 2, etc. ..., the locking angle α of 6 can be changed and adjusted.

For this reason, each string 1.2. ..., the sustain effect etc. of 6 can be changed to suit the content of the song, and can be changed quickly between consecutive performances, making it easy to perform a wide range of performances. be able to.

Furthermore, the fixed position of the tail piece 10 is always arranged perpendicular to each of the six strings, and as a result, the area for suppressing the guitar body 9 is relatively small, so that the guitar body as the diaphragm can be used as the diaphragm. At the same time, it is possible to eliminate the disadvantage that the vibrations described in No. 9, especially the vibrations in the bass region, are inhibited.

The tailpiece 20 shown in FIG. 5 shows a second embodiment.

In the figure, the through hole 12 is formed in exactly the same way as in the first embodiment.

On the other hand, the guide through grooves 21 are integrally formed with three through holes 12 in each of two adjacent strings.

Specifically, lateral grooves 22 are provided from three through holes 12 in each of two rows for two strings toward the inside of the rows, and each lateral groove 22 is provided in the center of the lateral grooves 22. A common longitudinal groove 23 is provided for common connection.

The other two sets of strings are formed in exactly the same way.

According to the second embodiment, the same effects as the first embodiment can be obtained based on a simpler configuration.

Moreover, FIG. 6 shows a tail piece 30 showing a third embodiment.

This tail piece 30 has a guide through groove 31 provided for each string, and a vertical groove 32 extending in the upper end surface of the tail piece 30 in FIG. 6, and this upper end surface. An opening 33 is formed in the opening 33 .

The rest of the structure is exactly the same as that of the first embodiment.

According to the third embodiment, the string can be attached to and removed from the tailpiece 30 by letting the end of the string come out through the opening 33, and in addition to the effects of the first embodiment, It is possible to quickly attach and detach strings.

Furthermore, FIG. 7 shows a tail piece 40 showing a fourth embodiment.
It is.

This tail piece 40 has a common longitudinal groove 42 extending to the upper end surface of the tail piece 40 in FIG. 7 in a guide through groove 41 provided for two adjacent strings. An opening 43 is formed in the upper end surface.

The rest of the structure is exactly the same as that of the second embodiment.

According to the fourth embodiment, the same effects as the third embodiment can be obtained based on a simpler configuration.

In the above embodiment, it is specified that three through holes 12 are formed in each case, but the present invention is not necessarily limited to this, and for example, there may be two in each case or four in each case.

As described above, according to the present invention, a plurality of locking through holes are formed for each string in a direction substantially perpendicular to the guitar body, and a plurality of locking through holes corresponding to at least one string are formed in a direction substantially perpendicular to the guitar body. Since a guide through groove connecting the through holes is provided, it is not only possible to simply set the string locking angle by changing it arbitrarily and stepwise as necessary, but also to set the string locking angle as needed. When changing strings, you can easily change and set the string locking angle by simply loosening the string without removing the entire string, using the guide through groove, and this makes it easy to set the string locking angle, especially in the bass section. Provides an unprecedented string locking mechanism that can obtain a straightforward sustain of string vibration suitable for differences in string thickness without inhibiting vibration, and can quickly adjust the vibration damping time, etc. can do.
