Description

  The present invention relates to a stringed end fixture for a stringed instrument, and more specifically, a stringed instrument that is attached to a body of a stringed instrument in which a string having a terminal on one end side is stretched to fix the terminal side of the string. The present invention relates to a string end fixture.

  Various stringed instruments such as guitars, violins, harps, etc. have strings laid by various methods. For example, as represented by a guitar, in a stringed musical instrument having a body, a neck protruding from the body, and a head provided at the tip of the neck, one end of the string is fixed to the body and the other end is a peg of the head. It is wound around and stretched so that it can be tuned. Moreover, in an electric guitar, an acoustic folk guitar, and the like, a string having a terminal at the end on one end side is used. Here, the string terminal is formed in an appropriate shape such as a ball shape, a ring shape, or a bullet shape, and is attached to one end side of the string. It is locked and fixed to the stop.

  The following shows an example of an electric guitar equipped with a tremolo unit (a device for vibratoing a string, also referred to as a vibrato unit) as shown in Patent Document 1 as a fixed structure on a string terminal side of a stringed instrument. 3 and FIG.

  The tremolo unit 100 includes a bridge plate 110 formed in a plate shape, and a locking block 120 formed in a block shape and integrated with a fixing screw 115 on the lower surface of the bridge plate 110. 1 is attached to the body 1 of the electric guitar so that the locking block 120 is accommodated in the unit accommodating portion 1a provided in the electric field.

  Here, the locking block 120 is provided with a storage locking hole 121 for storing and locking the terminal element 3 of the string 2, and the other end side of the string 2 is inserted into the storage locking hole 121. The terminal 3 of the string 2 is fixed to the tremolo unit 100 by locking the terminal 3 on one end side.

  On the other hand, the bridge plate 110 is attached to the body 1 with the attachment screw 130, but a gap S is provided between the lower surface of the front end of the bridge plate 110 and the body 1, and can be tilted with respect to the body 1. It has become. Further, the bridge plate 110 has a string 2 attached by a plurality of tension springs 150 that are hooked at one end to the locking block 120 and hooked at a hook 151 that is screwed into the unit accommodating portion 1 a of the body 1. It is biased in the direction of tension. In such a bridge plate 110, the operation of the arm 140 mounted on the arm mounting portion 141 causes the string 2 to tilt against the urging force of the tension spring 150 in a direction in which the string 2 is loosened. The string 2 is vibrato.

  The bridge plate 110 includes a saddle member 111 provided with a saddle 111a on which the string 2 is placed. The saddle member 111 is urged in the neck direction by a compression spring 113 and the string 2 is adjusted by an adjustment 112 screw. It is possible to move in the tensioning direction. Further, the height of the saddle 111 a of the saddle member 111 can be adjusted by an adjusting screw 114.

  In stringed instruments, the string tension, the so-called tension, is the type of the string (material and thickness) and the length of the string (for example, in the guitar as described above, it is wound around the peg of the head from one end fixed to the body. The length of the entire string up to the other end including the measured amount). For example, with the same tuning, a hard string will be less tensioned than a soft string, a thin string will be less tensioned than a thick string, and a shorter string will be longer. Tension is weaker than strings.

  Here, in the case of stringed instruments, there are cases where it is desired to adjust the string tension according to the individual preferences of the user. For example, when the type of string is changed, there is a demand for playing with the same tension as the string used so far. In addition, when down-tuning is performed with a lower sound than normal tuning, the tension becomes weak and a good sustain cannot be obtained, so that a desire to increase the tension arises.

  Conventionally, the following various methods have been used to adjust the tension of the strings, but each of these methods has a problem.

  First, there is a method of adjusting the tension by changing the number of turns of the string wound by the peg, but the number of turns suitable for winding on the peg is about 3 turns, and other than this suitable number of turns , Tuning becomes crazy. Therefore, it is not very preferable to adjust the tension of the string by the number of turns of the peg.

  Next, there is a method of adjusting the tension by changing the angle of the neck with respect to the body or the angle of the head with respect to the neck. However, with this method, it is difficult to individually adjust the tensions of a plurality of strings. Also, to change the neck angle or head angle requires a major modification of the stringed instrument. Therefore, it is not very preferable to adjust the tension of the string by the angle of the neck or head.

  The present invention has been made in view of the above circumstances, and in a stringed musical instrument in which a string having a terminal piece is stretched on one end side, a novel method capable of easily adjusting the tension of a string on the string terminal side. An object is to provide a string end fixture for stringed instruments.

The main means taken by the present invention to solve the above problems are as follows:
"A string end fixture for a stringed instrument that is attached to a body of a stringed instrument in which a string having a terminal on one end side is stretched to fix the terminal end of the string,
A fixture body having a female screw hole drilled in the direction of string tension;
A moving piece that has a string locking portion for locking a string terminal and a moving piece tool hanging portion on which a tool is hung, and is movably screwed into the female screw hole of the fixture body. Characterized string instrument string end fixture "
It is.

  Here, the string end fixture according to the present invention is not limited to one that fixes all strings with a single string end fixture in the case of a stringed instrument in which a plurality of strings are stretched. It may correspond to the strings individually, or may correspond to some of the strings such as two strings or three strings among all the strings.

  Further, the string end fixture according to the present invention is attached to the body of the stringed musical instrument, but is not limited to being directly attached to the body, and can be exchanged with a locking block of a ready-made tremolo unit as will be described later. Then, it may be attached indirectly to the body of the stringed instrument, such as via a bridge plate or via a separate pedestal.

  Further, as will be described later, the fixture main body may be a block-like one that accommodates the moving piece in the female screw hole, or may be a plate-like one. When the fixture body is plate-shaped, for example, the bridge plate shown in FIG. 4 is formed in an L-shaped cross section, and one protruding side is a protruding piece with a female screw hole, and the other side The side may be a substrate that can be attached to the body of the stringed instrument.

  Furthermore, the moving piece only needs to have a string locking portion for locking the string terminal and a moving piece tool hanging portion on which the tool is hung. And as a string latching | locking part, the accommodation latching hole which accommodates and latches a terminal element, the hook etc. which hook a terminal element can be illustrated. In addition, the moving piece tool hanging part includes a hexagonal head on which a hexagon wrench is hung, a single-letter groove on which a flathead screwdriver is hung, etc. A tool may be hung on the outer surface side, such as a so-called two-surface width formed by the following.

  In the string end fixture having the above-described configuration, the moving piece provided with the locking portion for locking the string terminal is movably screwed into the female screw hole of the fixture body. The fixed position of the string terminal relative to the body can be easily changed by screwing or screwing the moving piece with respect to the screw hole. This makes it possible to easily adjust the tension of the strings by changing the overall length of the strings.

  In addition, since the moving piece has a moving piece tool hanging portion for hanging the tool, the moving piece can be easily moved by the tool.

In the means described above,
“The fixture body is formed in a block shape,
The female screw hole accommodates the moving piece in the fixture main body,
The string locking portion of the moving piece is provided with a string insertion portion that allows a string to be inserted at one end side and cannot be inserted into a terminal piece, and the moving piece tool hanging portion that allows a terminal piece to be inserted at the other end side. Provided, and is configured by an accommodation locking hole for receiving a string terminal from the moving piece tool hanging portion side and locking the terminal.
A fixing piece that is screwed into the female screw hole and disposed on the moving piece tool hanging portion side of the moving piece, and presses and fixes the moving piece;
The fixed piece is provided with a terminal insertion portion that allows a terminal element to be inserted into one end side that is the moving piece side, and a fixed piece tool hanging portion that is capable of inserting the terminal element and is hooked with a tool on the other end side. String-end fixture for stringed instruments characterized by being provided "
Is preferable.

  In the string end fixture having the above-described configuration, the locking portion of the moving piece is configured by the holding locking hole that receives and locks the string terminal from the moving piece tool hook portion side. Even in a state where the moving piece is mounted in the female screw hole, the strings can be exchanged from the moving piece tool hanging portion side. Therefore, with the string end fixture of the above configuration, if the position of the moving piece is determined and fixed in advance so that the desired tension can be obtained according to the type of string to be used, each time the old string is replaced with a new string Therefore, it is not necessary to adjust the position of the moving piece, and it is excellent in convenience.

  By the way, if the moving piece is simply screwed into the female screw hole of the fixture main body, the moving piece may be moved carelessly due to vibration of the strings. In particular, since a tensile force is constantly applied to the string terminal, the moving piece easily moves in the direction in which the string is loosened. Moreover, since the moving piece is accommodated in the female screw hole of the block-shaped fixing device main body, even if it is moved, it is not noticed in appearance.

  Therefore, the string end fixture having the above-described configuration employs a separate fixing piece that comes into contact with the moving piece. This fixed piece abuts against the moving piece and presses the moving piece, thereby fixing the moving piece, and functions as a so-called loosening prevention of a screw such as a so-called double nut. Therefore, in the string end fixture having the above-described configuration, the moving piece can be firmly fixed, and the fixing piece can be prevented from moving carelessly.

  In addition, the fixed piece has a terminal insertion part through which the string terminal can be inserted at one end side, and a fixed piece tool hanging part through which the string terminal can be inserted and the tool can be hung at the other end side. Yes. Therefore, in the string end fixture having the above configuration, even when the moving piece is fixed by the fixed piece, the string can be exchanged from the fixed piece side without removing the fixed piece, and the convenience is excellent.

  The fixed piece tool hanging portion of the fixed piece may be operated with a tool different from the moving piece as a different form from the moving piece tool hanging portion of the moving piece. Is preferably in the same form as the moving piece tool hanging portion of the moving piece. By doing in this way, a moving piece and a fixed piece can be operated with a common tool, and the convenience can be improved.

In the means described above,
“The female screw hole is provided in a slanted manner in the fixture body”, and the string end fixture of the stringed instrument ”
Is preferable.

  Here, the inclined shape indicates that the fixing device is attached to the body of the stringed musical instrument directly or indirectly, but is not perpendicularly or parallel to the attachment surface.

  When the female screw hole is provided in the block-shaped fixture main body, if the female screw hole is provided in an inclined shape, the female screw hole can be elongated by an amount corresponding to the inclination. Thereby, the moving stroke of a moving piece can be set long and the string end fixture which can adjust the tension of a string in a wide range is realizable.

  As described above, according to the present invention, in a stringed instrument in which a string having a terminal piece is stretched on one end side, the string end fixing of a novel stringed instrument that can easily adjust the string tension on the string end piece side Tools can be provided.

It is a section side view showing an example of a string end fixture concerning the present invention. It is a fragmentary sectional side view which shows an example of a moving piece and a fixed piece. It is a perspective view which shows an example of a ready-made tremolo unit. FIG. 4 is a cross-sectional side view of a main part of a guitar equipped with the tremolo unit shown in FIG. 3.

  An example of an embodiment of a string end fixture for a stringed instrument according to the present invention will be described below in detail with reference to the drawings.

  The string end fixture of the stringed instrument according to the present invention is attached to the face of the body of the stringed instrument, or provided in the housing recess with the housing recess provided in the body, or a stringed instrument having a recess in the body in the first place. Although it can be used in various modes, such as being arranged in the recess using this recess, in the example described in detail below, it is replaced with a locking block of an off-the-shelf tremolo unit mounted on an electric guitar. Thus, the string end fixture that can adjust the tension of the string by the tremolo unit is shown, and the details of the tremolo unit are denoted by the same reference numerals as in FIGS.

  FIG. 1 shows an example of a string end fixture 50 of a stringed instrument according to the present invention.

  The string end fixture 50 includes a fixture body 10 made of steel (specifically, carbon steel such as S55C) formed in a block shape. Here, the fixture body 10 is attached to the tremolo plate 110 in place of the locking block 120 of the ready-made tremolo unit 100, and, like the locking block 120 of the ready-made tremolo unit 100, a fixing screw. 115 is attached to the tremolo plate 110.

  By the way, as a technique that can adjust the tension of the string on the peg side, a technique using a lock peg with a tension adjusting function can be exemplified in addition to the technique described above. Here, the lock peg with tension adjustment function can be fixed without winding the string, and the height of the post that fixes the string can be changed, and the tension of the string can be changed by changing the height of the post. Can be adjusted. However, when such a lock peg with a tension adjusting function is used, the appearance of the head changes greatly. Therefore, such a lock peg with a tension adjusting function is unacceptable for a vintage fan who loves an old type electric guitar, for example.

  On the other hand, in the ready-made tremolo unit 100 of the electric guitar as in this example, if the string end fixture 50 is used instead of the locking block 120, it is easy for a user who cares about the appearance to accept. . The locking block 120 of the tremolo unit 100 is originally accommodated in the body 1. Even if the string end fixture 50 is used instead of the locking block 120, there is no change in the appearance of the electric guitar. Because there is no.

  Further, when the string end fixture 50 is used instead of the locking block 120 of the ready-made tremolo unit 100, the fixture main body 10 is enlarged as much as possible within a range that can be accommodated in the unit accommodating portion 1a of the body 1. Is preferred.

  If the member for fixing the terminal element 3 of the string 2 is in a small block shape, the member itself vibrates greatly due to the vibration of the string 2, so that the vibration of the string 2 affects other strings 2, the body 1, and the like. There is a risk that the sound quality will be reduced. On the other hand, if the member for fixing the terminal element 3 of the string 2 is a large block shape, the member itself is difficult to vibrate even if the string 2 vibrates. Therefore, by making the fixture main body 10 into a larger block shape than the conventional locking block 120, it is possible to make the influence of the vibration of the strings 2 difficult to affect other strings 2, the body 1, etc., and the sound quality is lowered. It is because it can suppress.

  Further, in order to prevent the vibration of the string 2 from affecting other parts, it is desirable that the weight of the member for fixing the terminal element 3 of the string 2 is large. Here, while the locking block 120 of the conventional tremolo unit 100 is made of zinc, the fixture main body 50 of the present example uses steel having a specific gravity higher than that of zinc (specific gravity: about 7.1). (Specific gravity: about 7.8) is adopted. Therefore, the fixture main body 50 of this example is heavier than the locking block 120 of the ready-made tremolo unit 100, and from this point, the vibration of the string 2 can hardly be affected.

  Similar to the accommodation locking holes 121 of the locking block 120, the fixing tool main body 10 is formed with a number of female screw holes 11 corresponding to the number of strings 2 of the electric guitar at predetermined intervals. Here, each female screw hole 11 accommodates a moving piece 20 and a fixed piece 30 described later. Each female screw hole 11 is provided in a slanted manner rather than a right angle with respect to an upper surface that is a mounting surface (a surface that comes into contact with the bridge plate 110) attached to the body 1 via the bridge plate 110. More specifically, the female screw hole 11 is inclined toward the saddle 111 a of the tremolo unit 100. Further, one end side of the tension spring 150 is hooked on the lower surface of the fixture main body 10, and one end side of the tension spring 150 is accommodated in the recess 12 provided on the lower surface of the fixture main body 10. ing.

  Thus, in the string end fixture 50 of this example, since the female screw hole 11 of the fixture main body 10 is inclined, a space for forming a screw hole for the fixing screw 115 on the upper surface of the fixture main body 10, A sufficient space for forming the recess 12 that accommodates one end of the tension spring 150 on the lower surface of the fixture main body 10 can be secured. Moreover, since the female screw hole 11 of the fixture main body 10 is inclined toward the saddle 111a, the bending angle of the string 2 stretched from the saddle 111a to the fixture main body 10 can be relaxed.

  Further, in the fixture body 10 of the string end fixture 50 of this example, not only the female screw hole 11 is inclined, but also the height is set higher than that of the locking block 120 of the ready-made tremolo unit 100. ing. Therefore, a sufficient effective length of the female screw hole 11 can be ensured. In particular, in the string end fixture 50 of this example, since one end side of the tension spring 150 is accommodated in the concave portion 12 on the lower surface of the fixture body 10 as described above, the lower surface of the body 1 is fixed to the fixture body 10. It can be raised until it reaches the bottom surface.

  A moving piece 20 and a fixed piece 30 are mounted in the female screw hole 11 of the fixture main body 10. Here, the moving piece 20 accommodates and locks the terminal 3 of the string 2, and the tension of the string 2 is adjusted by moving the moving piece 20 within the female screw hole 11 of the fixture body 10. can do. Further, the fixed piece 30 firmly fixes the moving piece 20 by contacting and pressing the moving piece 20.

  Next, details of the moving piece 20 and the fixed piece 30 will be described with reference to FIG.

  As shown in FIG. 2, the moving piece 20 is constituted by a so-called imo screw in which a male screw that is screwed into the female screw hole 11 of the fixture main body 10 is engraved on the outer peripheral surface. Further, the moving piece 20 is provided with a string locking portion for locking the terminal element 3 of the string 2. Here, in this example, the string locking portion is configured by an accommodation locking hole 21 that penetrates in the axial direction and receives and locks the terminal 3 of the string 2. Moreover, the accommodation locking hole 21 includes a string insertion portion 22 that allows the string 2 to be inserted but the terminal element 3 not to be inserted, and allows the terminal element 3 of the string 2 to be inserted to the other end side. It is provided with a moving piece tool hanging portion 23 on which a tool can be hung. Specifically, the string insertion portion 22 has a circular shape, and the inner diameter thereof is set to be larger than the outer diameter of the string 2 and smaller than the outer diameter of the terminal element 3. Further, in this example, a hexagonal hole that can be used with a hexagonal wrench is adopted as the moving piece tool hanging portion 23, but this hexagonal hole has an inner surface dimension through which the terminal element 3 can be inserted. .

  In such a moving piece 20, the terminal piece 3 of the string 2 can be taken in and out through the moving piece tool hanging portion 23. Therefore, in this moving piece 20, the string 2 can be exchanged from the moving piece tool hanging portion 23 side even when the moving piece 20 is mounted in the female screw hole 11 of the fixture main body 10.

  As shown in FIG. 2, the fixed piece 30 is also constituted by a so-called potato screw in which a male screw that is screwed into the female screw hole 11 of the fixture body 10 is engraved on the outer peripheral surface, as shown in FIG. 2. Further, the fixed piece 30 is provided with a terminal insertion part 31 through which the terminal 3 of the string 2 can be inserted at one end side, and a fixed piece through which the terminal 3 of the string 2 can be inserted at the other end side. A tool hook 32 is provided. Specifically, the terminal element insertion portion 31 has a circular shape, and an inner diameter thereof is set larger than an outer diameter of the terminal element 3. Further, as the fixed piece tool hanging portion 32, a hexagonal hole that can share a hexagon wrench for operating the moving piece 20 is adopted, and this fixed piece tool hanging portion 32 is the same as the moving piece tool hanging portion 23 of the moving piece 20. In this form, the inner dimension is such that the terminal 3 can be inserted.

  According to such a fixing piece 30, even when the moving piece 20 and the fixing piece 30 are mounted in the female screw hole 11 of the fixing body 10 and the moving piece 20 is firmly fixed by the fixing piece 30, the fixing piece 30 is fixed. The string 2 can be exchanged from the piece 30 side.

  Further, the fixed piece tool hanging portion 32 of the fixed piece 30 has a bottom so that a tool which is a hexagon wrench does not penetrate the fixed piece 30. Therefore, when the fixed piece 30 is arranged behind the moving piece 20 and the moving piece 20 is fixed, the tip of the tool inserted into the fixed piece tool hanging portion 32 of the fixed piece 30 is the moving piece tool hanging portion 23 of the moving piece 20. It is possible to operate only the fixed piece 30 with a tool without reaching the position and turning the moving piece 20.

  As mentioned above, although an example of the string end fixture according to the present invention has been described, the string end fixer according to the present invention is not limited to the above-described example, and can be appropriately changed without departing from the gist of the present invention. is there.

  For example, it may not be used in place of a locking block of a ready-made tremolo unit mounted on an electric guitar, but may be directly attached to the face of the guitar. The string end fixture according to the present invention is not limited to electric guitars and acoustic folk guitars, and can be applied to various stringed instruments in which strings having terminals are stretched.
