Description

  The present invention relates to a wind instrument pad used as a key for opening and closing a tone hole for changing a pitch provided in a wind instrument.

  Conventionally, a pad for opening and closing a tone hole for a wind instrument has a structure in which a felt is wrapped with a pad skin formed of a thin film of an internal organ of an animal and a skin of an intestine and glued to a mount. The pad mount side is attached to the cup, and the felt side of the pad is closely attached and separated from the opening end of the tone hole, so that the tone hole is opened and closed, and the air flow blown from the shed flows out of the wind instrument. By preventing this, the frequency of the airflow flowing through the tube changes, and the pitch is changed.

Various improvements have been made to the adhesiveness of the pad to the tone hole because it affects the pitch, sound quality, and the like. For example, as disclosed in Patent Document 1, there is one in which a circular groove is provided in a metal cup and a disk-shaped artificial leather and silicon rubber are inserted therein. Further, in Patent Document 2, there is one in which the entire pad is formed of special silicon rubber, but these are all improved to improve the adhesion of the pad, and vibration of the air flow flowing through the tube body It does not take into account the effect of vibrations when it is transmitted to the pad.

In practice, the above components are provided in close contact with each other.

  The pad 10 includes a resin base 11 mainly made of a cup-shaped resin as a base, a gel-shaped resin body 12 mounted in the resin base 11, and a leather film mounted on the surface of the gel-shaped resin body 12. 13, a resin film 14 is provided so as to cover the surface of the leather film 13 and the outer periphery of the resin base 11, and a thin-film pad made of animal intestinal skin so as to cover the surface of the resin film 14. A skin 15 is provided. The pad skin 15 is provided so as to cover the back surface 11 e of the resin base 11, and its end is fixed to the back surface of the resin base 11 with a mount 16.

  The internal structure of the pad 10 that is a feature of the present invention will be described in detail.

  FIG. 4 is a plan view of the resin base 11, and FIG. 5 is a longitudinal sectional view of the resin base 11. The resin base 11 has a disc shape as a whole, a cylindrical outer peripheral wall portion 11c protruding from the bottom surface portion 11a is formed at the outer peripheral end, and a through hole 20 is formed in the center so as to penetrate the bottom surface portion 11a. Is formed. Further, a cylindrical inner peripheral wall portion 11d is formed around the through hole 20, and protrudes in the direction substantially perpendicular to the bottom surface portion 11a in the same direction as the outer peripheral wall portion 11c. Moreover, as shown in FIG. 3, the outer peripheral wall part 11c inclines so that it may spread a little toward the edge part and an outer-diameter direction. This inclination is provided so that the surface of the resin film 14 can be evenly stretched with a predetermined tension when an end portion of the resin film 14 described later is bonded to the outer peripheral surface of the inclined part. The material of the resin base 11 is mainly composed of a hard resin, for example, most preferably composed of a resin composed of a polymer material such as Duracon (registered trademark), as long as it has similar hardness and characteristics. Other materials can also be used.

  In a cylindrical recess formed between the outer peripheral wall portion 11c and the inner peripheral wall portion 11d, a disc-like gel-like resin body 12 having a through hole 12a provided in the center is inserted, and the gel-like resin body is inserted. The one end surface 12 a of 12 is provided in contact with the inner surface 11 e of the bottom surface portion 11 a of the base 11. FIG. 6 is a plan view thereof, and FIG. 7 is a longitudinal sectional view thereof. The through hole 12a has substantially the same diameter as the outer peripheral surface of the inner peripheral wall portion 11d of the resin base 11, and is inserted into the outer peripheral surface of the inner peripheral wall portion 11d with almost no gap. Moreover, the outer peripheral surface 12b of the gel-like resin body 12 has a diameter substantially the same as the inner peripheral surface of the outer peripheral wall portion 11c of the resin base 11, and is inserted into the outer peripheral surface with almost no gap. However, since the outer peripheral wall portion 11c is inclined, a gap corresponding to the inclination may be generated, or the outer peripheral surface 12b of the gel-like resin body 12 may be similarly inclined so as to fill the gap.

  The gel-like resin body 12 is inserted so as to be surrounded by the concave resin base 11. Thereby, the easily deformable gel-like resin body 12 can be maintained and held in the resin base 11 in a predetermined shape. The base 11 has a configuration in which the outer peripheral wall portion 11c and the inner peripheral wall portion 11d are integrated. However, if the gel-like resin body 12 is maintained and held, each or only one of them is a separate cylinder. You may make it comprise from a shaped member.

  Furthermore, a leather film 13 formed in a predetermined thin film shape is provided on the other substantially circular plane 12d of the gel-like resin body 12 so as to be in contact with the other substantially circular plane 12d. FIG. 8 is a plan view of the leather film 13, and FIG. 9 is a longitudinal sectional view. As a shape, it is a flat plate shape, which is substantially the same as the gel-like resin body 12, that is, the outer peripheral surface 13b and the inner peripheral surface 13a are substantially the same as the outer peripheral surface 12b and the inner peripheral surface 12a of the gel-like resin body 12. Although the diameter is different, the gel-like resin body 12 has a thickness of about 1 mm, whereas the leather film 13 has a thickness of about 0.4 mm. The material of the leather is preferably deer or calf, but other materials can be used as long as they are materials having equivalent properties such as artificial leather.

  Further, the total thickness of the gel-like resin body 12 and the leather film 13 is set to be approximately the same as the depth of the concave portion provided in the resin base 11. Accordingly, the position of the surface of the leather film 13 is substantially flush with the upper end surfaces of the outer peripheral wall portion 11c and the inner peripheral wall portion 11d provided on the resin base 11.

  A resin film 14 made of a polyvinyl chloride film having a thickness of about 0.1 to 0.2 mm is provided on the surface of the leather film 13. The resin film 14 is provided so as to cover the entire leather film 13 from the upper end surface of the inner peripheral wall portion 11d of the base 11 to the outer peripheral surface of the outer peripheral wall portion 11c. The resin film 14 is glued and fixed on the upper end surface of the inner peripheral wall portion 11d and the outer peripheral surface of the outer peripheral wall portion 11c. Therefore, the resin film 14 can be fixed to the resin base 11 in a state where a predetermined tension is applied. Further, since the surface of the leather film 13 is substantially the same height as the upper end surface of the outer peripheral wall portion 11c of the resin base 11, it is arranged so as to be in contact with the resin film 14 provided on the surface without any gap. Will be.

  Further, the pad skin 15 is provided so as to cover the entire pad 10 so as to cover the resin film 14 so as to reach from the upper end surface of the inner peripheral wall portion 11 d of the base 11 to the back surface 11 e of the bottom surface portion 11 a of the base 11. The one end is glued and fixed to the upper end surface of the inner peripheral wall portion 11d of the base 11, and the other end is glued and fixed to the back surface 11e. The other end is further fixed to the back surface 11e of the bottom surface portion 11a of the base 11 by a flat mount 16 having a through hole at the center.

  The pad 10 has the following operations from the above configuration.

  When the pad 10 is positioned so as to close the tone hole 51, the end surface of the tone hole 51 is in direct contact with the pad skin 15, but the resin film 14, the leather film 13, and the gel-like resin body 12 are in contact with each other on the back surface. Are arranged as follows. Therefore, the vibration of the air flow flowing through the pipe body 50 is transmitted to the gel-like resin body 12 through the pad skin 15, the polyvinyl chloride film 14, and the leather film 13, and the vibration in the gel-like resin body 12 is transmitted. Will pass. Since the gel-like resin body 12 easily transmits vibrations due to the characteristics of the material, the vibration of the airflow flowing through the tube body 50, that is, the sound is transmitted without being attenuated, and the sound can be maintained.

  The gel-like resin is easy to transmit vibration, but easily deforms and it is difficult to maintain the shape, but the gel-like resin body is surrounded by the cup-like resin base 11 as in the present invention. 12 is inserted and held in the resin base 11, so that the shape can be held in the pad. Furthermore, by providing the leather film 13 on the top of the gel-like resin body 12, it becomes possible to give softness to the sound quality.

  When the pad 1 comes into contact with the tone hole 51, a predetermined pressing force acts on the pad and the surface of the pad 1 sinks. In particular, in the case of the present invention, since the gel-like resin body 12 is inserted inside, the indentation is larger than that of a conventional felt material. Therefore, by providing the resin film 14 on the surface of the leather film 13 so as to have a predetermined tension, it becomes possible to prevent the dent from being applied to the pressure when the pad 1 is pressed against the tone hole 51. . The pad skin provided on the outermost surface of the pad 1 is used to prevent the pad 1 from sticking to the opening end of the tone hole 51 due to moisture or the like.

  In the case of the first embodiment, the through hole 20 into which the screw portion for fixing the pad 10 is inserted into the cup 1 is provided. However, in the so-called ring key in which a similar through hole is also provided in the cup 1. It can be used similarly. In this case, the pad is not fixed by screws and washers, but is press-fitted and fixed to the outer peripheral surface of the ring-shaped annular portion provided at the center of the cup.

(Embodiment 2)
In the first embodiment, the through hole 20 into which a screw portion for fixing to the key is inserted is formed in the center of the pad 10, but a plurality of keys having various diameters are used for the wind instrument, In particular, in the case of a small-diameter key, the pad may be directly bonded and fixed to the inside of the key cup without providing a fastening screw portion in the center. The configuration in this case will be described below.

  FIG. 10 shows a longitudinal sectional view of a pad 30 for a small-diameter key having no through hole in the center.

  Each of the resin base 31, the gel-like resin body 32, the leather film 33, the resin film 34, the pad skin 35, and the mount 36 has a shape without the central through-hole formed in each of the first embodiment. Although there is a difference in size, the shape of each has substantially the same shape.

  The present invention is used for a key of a flute or other wind instrument, and the pad has been configured for the purpose of improving the sealing performance of the key, but the pad itself has a function of maintaining and sustaining the sound. It can be used to expand the expressiveness of musical instruments and enrich the sound.
