Description

  The present invention relates to a structure of a fixing device for fixing a lead to a mouthpiece of a wind instrument.

  With a saxophone or clarinet that is a wind instrument, when the player blows in the mouth, the part called reed vibrates and produces sound. An instrument having such a lead is also referred to as a lead instrument. This lead is a thin piece that easily vibrates and vibrates to become a sound source, and its material greatly affects the sound quality. The material is often bamboo such as warm bamboo, bamboo bamboo, bamboo bamboo, and plastic.

The quality of this lead is subtle and has a great impact on sound quality. For this reason, players value their dedicated leads.
This lead is attached to the mouthpiece portion of the musical instrument by wrapping it with a device called a ligature made of metal or the like. The quality of this installation also affects the sound quality. The price of the equipment is also expensive.
In the conventional metal ligature 101, for example, as shown in FIG. 4, a plate 107 for holding the lead 105 is disposed on the outer surface of the lead 105 disposed in contact with the mouthpiece 103. And the band 109 is attached by winding the outer periphery of the mau piece 105. Both ends of the metal band 109 are connected by welding via a welding piece 111. The welding piece 111 is provided with a pressing screw 113 that passes through and is screwed, and the tip of the pressing screw 113 presses the outer surface of the plate 107. The lead 105 is fixed by the pressing of the pressing screw 113. A driver groove (not shown) is formed at the rear end of the pressing screw 113, and is pressed by rotating the pressing screw 113 with a tool called a screwdriver.

The metal constituting the ligature is different from the material of the mouthpiece or lead, and adversely affects the sound quality.
In Patent Document 1, by providing spacer members at three locations in the circumferential direction of the mouthpiece so that the ligature and the mouthpiece are not in contact with each other, there are only three thin spring members corresponding to the belt of the ligature. And the structure which contacts a mouthpiece via a spacer member is proposed.

US patent Japanese abstract 55787776

However, in Patent Document 1, depending on the material of the spacer member, the sound quality is still adversely affected. Further, a thin spring member that is not a belt cannot be fixed with a sufficiently strong force.
Moreover, although the ligature which has the conventional belt can be fixed with stronger force, it cannot respond to the difference in the shape of the mouthpiece. In other words, not only the lead but also the mouthpiece is a consumable item, and must be replaced. Also, the mouthpieces of the same manufacturer and the same model number may be slightly different in shape. If the shapes are different, the ligature may not cope well. In that case, you must purchase another ligature that can be accommodated. Reeds, mouthpieces, and ligatures are each expensive and preferably compatible with each other.

  In order to solve the above-described problems, an object of the present invention is to provide a lead fixing device that hardly adversely affects the sound quality of a musical instrument and can easily cope with a mouthpiece having a different shape.

  In order to solve the above problems, the first invention is a fixing device for fixing a lead to a mouthpiece of a wind instrument, wherein the lead is disposed in contact with the mouthpiece and is in contact with the outer surface of the lead. Via the first lead piece arranged, the second and third lead pieces arranged at two places in the circumferential direction on the outer surface of the mau piece, and the three lead pieces arranged at substantially equal intervals in the circumferential direction. A band that is wound around the outer periphery of the mau piece, a rotary shaft that is rotatably connected to both ends of the band, and a pressing screw that is provided integrally with the rotary shaft and presses the first lead piece. And a pressing plate provided at the tip of the pressing screw and pressed by the first lead piece.

According to the second invention, the three lead pieces have a size that can be formed by cutting an old lead arranged on the mouthpiece, and contact the mouthpiece on the curved outer surface of the lead. The lead fixing device is characterized.
According to a third aspect of the present invention, the pressing screw is provided at a rear end and can be rotated by a finger, and a male screw that is screwed into a female screw hole formed at a center of the rotating shaft and perpendicular to the shaft. And a lead fixing device.

  According to the first, second, or third invention, three lead pieces are used as spacer members at three locations. Therefore, since the spacer member is essentially made of a material that is compatible with the mouthpiece and the musical instrument, the sound quality of the musical instrument is hardly adversely affected. This was confirmed by actual performance.

  In addition, as the other group, the band, the second and third lead pieces rotate slightly around the rotation axis, while maintaining substantially the same posture as one group, with respect to the pressing screw, the rotation shaft, and the first lead piece. Therefore, it is possible to fix the lead with a firm and strong force corresponding to mouthpieces having different shapes.

According to the second or third invention, since the three lead pieces can be formed by cutting the old lead, it is possible to suppress adverse effects on the sound quality of the musical instrument without incurring costs.
Further, each lead piece comes into contact with the mouthpiece on the curved surface of the lead, so that the contact point is reduced and excellent sound can be obtained.
According to the third aspect of the present invention, the pressing screw can be operated with a knob provided at the rear end and rotatable with a finger, and the lead can be exchanged without requiring a tool. In addition, the pressing screw is provided perpendicular to the center of the rotating shaft, and rotation around the rotating shaft is performed without impairing the pressing force of the pressing screw. Therefore, the lead can be fixed with a stronger and stronger force.

An embodiment of the present invention is shown in FIGS.
The device of this embodiment is a fixing device 5 that fixes a lead 3 to a mouthpiece 1 of a saxophone that is a wind instrument.
As shown in FIG. 1, the mouthpiece 1 has a substantially cylindrical cross section, but only a portion that blows in has a flat space. One surface of the flat space has an open shape (not shown), and the lead 3 is disposed in contact with the open portion. Thereby, the lead 3 constitutes one surface of the flat space.

The lead 3 is fixed to the mouthpiece 1 with a metal band 7. Then, three lead pieces 9 (11, 13, 15) are used as spacers for the portions to be fixed.
First, the first lead piece 11 is disposed in contact with the outer surface of the lead 3 (lower side in FIG. 1). Next, the second and third lead pieces 13 and 15 are arranged at two locations in the circumferential direction on the outer surface of the maupiece 1.
These three lead pieces 9 are arranged at substantially equal intervals in the circumferential direction of the mau piece, that is, at intervals of approximately 120 degrees.
As shown in FIG. 3, these three lead pieces 9 have a size that can be formed by cutting an old lead 17 that has been arranged in the mouthpiece 1 in the past.
That is, as shown in FIGS. 2A and 2B, the lead 3 has an elongated and thin tongue shape, and the tip is thinner, so that it tends to vibrate. The cross-section is a thin crest-like shape, one surface is curved and the other surface is a plane. It is attached to the mouthpiece 1 with the curved surface 19 facing outward.

A portion having a constant thickness behind the lead 3 is cut. The length to be cut corresponds to the width of the band 7 described later. Three lead pieces 9 are made in the same manner.
As shown in FIGS. (C) to (F), two of them are the second and third lead pieces 13 and 15, with the curved surface 19 on the inside, and the contact surface with the mau piece 1 is made smaller.
As shown in FIGS. (G) to (I), the other lead piece 9 is the first lead piece 11 and further cut into two pieces in the width direction. Then, the curved surface 19 is set to the inner side, and the rearrangement cut surface is set to the outer side to be adjacent to each other (FIG. (I)). This rearrangement enables stable contact with the curved outer surface of the lead 3.

  As shown in FIGS. 1 and 2, a band 7 is wound around and attached to the outer periphery of the mau piece 1 through these three lead pieces 9. Both ends of the band 7 are connected by a rotating shaft 21. That is, the connecting hole 23 is opened at both ends of the band 7, the rotating shaft 21 penetrates, and the flange 25 is formed as a stopper at the penetration destination. In this way, the band 7 is provided so as to be rotatable with respect to the rotating shaft 21.

A pressing screw 27 is provided integrally with the rotating shaft 21 to press the first lead piece 11. That is, the pressing screw 27 is provided with a knob 29 at the rear end for rotating with the finger. A female screw hole 31 is formed in the center of the rotating shaft 21 so as to be orthogonal to the axis of the pressing screw 27. A male screw 33 that is screwed into the female screw hole 31 is formed on the outer periphery of the pressing screw 27. A pressing plate 35 is provided at the tip of the pressing screw 27 and is pressed against the first lead piece 11.
A mounting male screw 37 projects from the outer side of the pressing plate 35 and is screwed into a mounting female screw 39 formed in a hole at the tip of the pressing screw 27 for mounting.

"Effect of the embodiment"
According to this embodiment, three lead pieces 9 are used as spacer members at three locations. Therefore, the spacer member is essentially made of a material that is compatible with the mouthpiece 1 and the wind instrument. Therefore, the sound quality of the musical instrument is not adversely affected by the vibrations of the different materials. This was confirmed by the inventor's actual performance. Natural sound was confirmed.

Moreover, since each lead piece 9 contacts the mouthpiece 1 on the curved outer surface, the contact point is reduced, the feeling of blowing is light, and excellent soft sound can be obtained.
Further, the pressing screw 27, the rotating shaft 21, and the first lead piece 11 maintain substantially the same posture as a group. As another group with respect to this group, the band 7, the second and third lead pieces 13 and 15 maintain substantially the same posture. Then, the other group rotates slightly around the rotation axis 21 with respect to the group. Because of this rotation, each lead piece 9 fits corresponding to the mouthpiece 1 having a different shape, and the lead 3 can be fixed to the mouthpiece 1 with a firm and strong force.

Furthermore, since the three lead pieces 9 can be formed by cutting the old lead 17, it is possible to suppress adverse effects on the sound quality of the wind instrument without incurring costs compared to the case of purchasing a new lead 3 for cutting. .
Further, the pressing screw 27 can be operated by a knob 29 provided at the rear end and rotated by a finger, and the lead 3 can be replaced without requiring a tool for operation. In addition, the pressing screw 27 is provided orthogonal to the center of the rotating shaft 21 and rotates around the rotating shaft without impairing the pressing force of the pressing screw 27. Therefore, the lead 3 can be fixed with a stronger and stronger force corresponding to the mouthpiece 1 having a different shape.

"Other embodiments"
In the above-described embodiment, the fixing device 5 that fixes the lead 3 to the mouthpiece 1 of the saxophone has been described. However, in other embodiments, the lead is fixed to the mouthpiece of another wind instrument such as a clarinet other than the saxophone. The present invention can also be implemented as an apparatus.
