DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a fret for a stringed instrument attached to a fingerboard of a stringed instrument such as a guitar.

[0002]

2. Description of the Related Art A fingerboard of a stringed musical instrument is generally provided with a plurality of frets for a stringed musical instrument to indicate the pitch of a musical tone to be played.

The structure of such a fret for a stringed instrument is as follows.
FIG. 1, FIG. 2 and FIG. 6 of JP-A-53-161620 have already been known. The structure of the fret and the mounting process thereof will be outlined below.

The fret includes a substantially semi-cylindrical instep 1 and a mounting strip 2 extending downward from the lower surface of the instep 1.
And an enlarged strip 3 formed at the tip of the mounting strip 2.
It is composed of

The fingerboard 4 of the stringed instrument has an elongated groove 5 into which the mounting strip 2 of the fret can be inserted.
Are formed.

Accordingly, the groove 5 provided in the fingerboard 4 is provided.
Then, by inserting the mounting strip 2 of the fret, the enlarged strip 3 of the mounting strip 2 is locked on the inner surface of the groove 5, and the fret is mounted on the fingerboard 4 of the stringed instrument.

[0007]

However, it is difficult to form a corner formed at the boundary between the instep of the fret for a stringed instrument and the mounting strip so as to form a perfect right angle. From the strip to the round part of the instep, a gently expanding flared bent surface is formed.

Therefore, when the mounting strip is inserted into the groove of the fingerboard, as shown in FIG. 4, it is locked in the middle of the inclined surface, and the insertion portion 6 is completely inserted to the base. It may not be possible.

In this case, the lower surface 4 of the instep 2 of the fret does not contact the edge of the groove 11 of the fingerboard 10, especially the edge of the groove 11, and a slight gap is formed between the instep 2 and the fingerboard 10. Since A is formed, there is a possibility that the fret rattles, and the sound played when the stringed instrument is played becomes cloudy.

Accordingly, an object of the present invention is to provide a fret for a stringed instrument that can be attached to a fingerboard such that no gap is formed between the instep and the fingerboard of the stringed instrument.

[0011]

Means for Solving the Problems] Thus, stringed instrument frets according to the present invention includes a large Kinoemaru portion than the grooves formed on the fingerboard of the stringed instrument, prior to extending from the bottom surface of such Kinoemaru portion
Composed of at least of at inserting portion and which is fitted into the groove of the serial fingerboard
In stringed instrument frets that, the insertion portion, the instep
It extends vertically to the lower surface of the round part, and
When multiple protrusions are formed on both sides in the hand direction,
In addition, of the both sides where the protrusion is formed,
Extending in the longitudinal direction of the insertion portion along the boundary portion and
It is characterized in that it has a recess recessed in the center direction of the insertion portion .

[0012]

According to the present invention, a recess is formed at the base of the insertion portion along the boundary with the instep and is recessed toward the center of the insertion portion.
A gentle hem expansion from the insertion part to the instep
To avoid the problem of forming a sloping bent surface
Can be, because even the base of the insertion portion becomes fully inserted in the groove of the finger plate, it can be brought into contact with the lower surface of the edge portion and Kinoemaru portion of a groove formed on the fingerboard of the stringed .

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an example of a fret 1 for a stringed instrument according to the present invention. The fret 1 for a stringed instrument is made of a metal which is attached to a plurality of stringed instruments such as a guitar, a ukulele, a mandolin and the like, and is used to indicate the pitch of a musical tone to be played.
It is basically composed of

The instep 2 is substantially semi-cylindrical and has a curved upper surface 3 and a flat lower surface 4. The instep 2 has a longitudinal dimension substantially equal to a lateral width of a fingerboard 10 of a stringed instrument described later, and a lateral dimension of the instep 2 is larger than a width of a groove 11 provided in the fingerboard 10. Is also bigger.

The other insertion portion 6 extends downward from the instep 2, that is, perpendicular to the lower surface 4 of the instep 2, and extends in the longitudinal direction of the instep 2. It has a plate shape. The thickness of the insertion portion 6 in the width direction has a dimension capable of being inserted into the groove portion 11 provided in the fingerboard 10, and the length from the base end to the tip of the round portion on the side of the groove portion 11 The dimensions are almost the same as the depth. Also, the insertion portion 6
On the both sides with respect to the longitudinal direction, a plurality of protruding portions 7 in the shape of a variable triangular pyramid whose apex is shifted from the center point are alternately formed.

The insertion portion 6 has depressions 8, 8 at both sides of the protrusion 7 at the boundary with the instep 2. 1 and 2 are shown in FIGS.
As is clear from FIG. 3 and FIG.
It is recessed and extends in the longitudinal direction of the insertion portion 6. Accordingly, it is possible to prevent the inclined surface from being formed in the skirt portion 2 from the insertion portion 6 to the instep 2.

The fingerboard 10 to which the fret 1 for a stringed instrument is attached is not shown in its entirety, but extends from a box-shaped main body of the stringed instrument. Are provided in the horizontal direction.

Therefore, according to the above configuration, as shown in FIG. 3, by inserting the insertion portion 6 into the groove 11 of the fingerboard 10 or the like, the protrusion 7 is locked to the inner surface of the groove 11 and the stringed musical instrument. The fret 1 is attached to the fingerboard 10 and the insertion portion 6 can be inserted into the groove 11 even to its base end portion.
The lower surface 3 of the instep 2 and the surface of the fingerboard 10, particularly the edge of the groove 11, come into contact with each other.

It should be noted that in the above-described embodiment, the projection 7 having a triangular pyramid shape is formed in the insertion portion 6 as a locking means for locking in the groove portion. The structure of the locking means is not particularly limited as long as the fret 1 is used, and it goes without saying that the fret 1 may not have the locking means.

[0021]

As described above, according to the fret for a stringed musical instrument according to the present invention, by forming a recess at the base of the insertion portion along the boundary with the instep, the base of the insertion portion is formed. Can also be completely inserted into the groove, and the fringe of the stringed instrument does not rattle because the edge of the groove and the lower surface of the instep come into contact with each other. For this reason, it is possible to prevent the sound played when playing the stringed instrument from becoming cloudy.
