Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a shakuhachi, which is one of the Japanese musical instruments.

[0002]

2. Description of the Related Art The shakuhachi is one of the representative Japanese musical instruments, and a bamboo flute that is played by putting the lips on the mouthpiece has been mainly used. Many people want to learn shakuhachi because they are fascinated by the unique sounds of shakuhachi.

[0003]

However, even if an ordinary person tries to get familiar with the shakuhachi for beginner practice, it is generally expensive and it is difficult to purchase the shakuhachi. Also, in recent years, there is a movement to introduce Japanese musical instruments to elementary and junior high schools for the development of Japanese music, but when the shakuhachi were purchased by the school side and the student side, the price was a bottleneck. Furthermore, since the shakuhachi is a vertical flute that blows with its lips directly on the mouth as mentioned above, there is a problem in reusing it even if only the school side purchases it, unlike other percussion instruments, string instruments, etc. I did not go.

The present invention solves the above-mentioned problems. The shakuhachi is designed so that elementary and junior high schools can easily purchase it, and the students themselves can purchase and practice it without much burden, so that they can learn with familiarity. The purpose is to provide.

[0005]

[Means for Solving the Problems] In order to achieve the above object,
The gist of the invention of claim 1 is that the mouthpiece side short pipe can be separated at a node near the mouthpiece, and the mouthpiece side short pipe can be detachably connected to the remaining portion. It is on the shakuhachi. The gist of the invention of claim 2 is that, in a shakuhachi in which an upper pipe and a lower pipe are separable, and the both are connected, the upper pipe is further divided into two parts, that is, a singing mouth side short pipe and an upper pipe remaining portion. The shakuhachi is characterized in that the short pipe on the song mouth side can be detachably connected to the remaining portion of the upper pipe in a detachable manner. The gist of the invention of claim 3 is that the upper pipe and the lower pipe are separable,
In the shakuhachi in which both are connected, both ends of the lower pipe are characterized in that the pipe hole gradually becomes smaller from the end point toward the central region of the lower pipe.

According to the first and second aspects of the invention, the singing mouth side short pipe is separable into the remaining portion (or the upper pipe remaining portion), and the singing mouth side short pipe is the remaining portion (or the upper pipe). If the school side prepares other common parts excluding the mouthpiece side short pipe where the mouthpiece exists, the students can purchase only the mouthpiece side short pipe, It doesn't cost much. It will become a regular shakuhachi if it is connected to the school side. And even the singing mouth side short pipe produces a sound, which is useful for shakuhachi practice. According to the first aspect of the invention, if the short pipe on the mouthpiece side can be separated at the node near the mouthpiece as a boundary, since the node has a thicker wall than other portions, the strength of the connecting portion can be maintained. Also, when the singing mouth side short pipe is separated at the knot, when the singing mouth side short pipe is connected to form a shakuhachi, it becomes difficult to tell whether or not the appearance is connected due to the piling shape peculiar to the knot, It is also excellent from an aesthetic point of view. As in the invention of claim 3, when both ends of the lower pipe gradually become smaller from the end point toward the central region of the lower pipe, a tapered draft is formed toward both ends of the lower pipe. Since it can be easily formed into a shape, the lower pipe can be easily manufactured and the cost of the product can be reduced.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The shakuhachi according to the present invention will be described in detail below. 1 to 5 show one embodiment of the shakuhachi of the present invention, FIG. 1 is an exploded perspective view thereof, FIG. 2 is a front view of a shakuhachi formed by assembling the parts of FIG. 1, and FIG. 2 is a front view of (a), a right side view of (b),
(C) is a rear view, (D) is a plan view, (E) is a bottom view,
The left side view appears symmetrical to the right side view. FIG. 4 shows FIG. 1 and FIG.
FIG. 5 is a front sectional view and an exploded view of a lower pipe of another embodiment.

The shakuhachi of this embodiment is made of a synthetic resin such as ABS and is shaped like a genuine bamboo product. Like the real thing, the shakuhachi's upper end is a song mouth made by forming an inclined surface 1
1 and 7 verses f from the song mouth 11 to the pipe butt 31
_{It is} shakuhachi formed with _{1 to} f ₇ . The shakuhachi is provided with first to third finger holes 38 on the front side of the lower tube 3, and the upper tube A has a fourth finger hole 28 on the front side and a fifth hole on the back side thereof. 29
Is provided.

In the shakuhachi, the upper pipe A and the lower pipe 3 are separated and formed by the intermediate joints 25 and 39, and if both are connected, the length of the shakuhachi is a standard pipe having a length of 1 shaku 8 inch (about 54.5 cm). Become eight.
A reinforcing metal ring R (or rattan) is wound around the connecting portion of the intermediate joints 25 and 39.

The upper pipe A is divided into a singing mouth side short pipe 1 and an upper pipe remaining portion 2. The singing mouth side short pipe 1 is separated from the upper pipe remaining portion 2 as a separate body at an almost midpoint of the second section f ₂ (the second side section f counting from the side of the mouthpiece 11) near the mouthpiece 11. It
Both 1 and 2 can be detachably attached. When the singing mouth side short pipe 1 and the upper pipe remaining portion 2 are connected and attached, an upper pipe A as shown in FIG. 2 is obtained. Connecting part 14,2
Since 4 is a node f, it is difficult to understand that the upper pipe A is connected, and the appearance is good. Further, since the joint f has a large wall thickness, the connecting portions 14 and 24 between the singing mouth side short pipe 1 and the upper pipe remaining portion 2 are easily formed. Upper tube remaining part 2
On the side connected to the singing mouth side short pipe 1, a tubular connecting portion 24a having a reduced outer diameter is provided, while the singing mouth side short pipe 1 has a thick wall portion from the straight pipe portion 1a to the node f _2. Utilizing the rising, the connection expanding portion 14a fitted to the cylindrical connecting portion 24a
Is provided. When the connecting portions 14 and 24 are fitted to each other to assemble the mouthpiece side short pipe 1 and the upper pipe remaining portion 2, one upper pipe A is formed. Tubular holes 10 and 20 on the mouthpiece side short pipe 1 and upper pipe remaining part 2
Communicate with each other to form the upper pipe A.

The upper pipe A is roughly divided into a singing mouth side short pipe 1 and an upper pipe remaining portion 2. The reason for the halving is that, firstly, the shakuhachi other than the singing mouth side short pipe 1 is divided. If the school side prepares the part as a common area, elementary and junior high school students will only need to purchase the mouthpiece side short pipe 1 that the lips directly touch. This is because the cost burden on the student side is small. Secondly, if the singing mouth side short tube 1 is used, the shakuhachi sound will be produced and the shakuhachi can be practiced. The singing mouth 11 in the singing mouth side short pipe 1 is originally a part of the shakuhachi, and leads to practice of the shakuhachi itself. Thirdly, the sound is much easier to produce than the upper pipe A in which the singing mouth side short pipe 1 and the upper pipe remaining portion 2 are connected, and more easily than the shakuhachi in which the upper pipe A and the lower pipe 3 are connected, which is convenient for beginners. Because. You can take the steps to purchase the whole shakuhachi when you become interested or improve. Fourth, the length of the mouthpiece side short pipe 1 is about half the length of the upper pipe A, and it is easy for a student to put it in a bag or the like and carry it to a school or the like.

By the way, the place where the length of the upper pipe A is roughly divided into the singing mouth side short pipe 1 and the upper pipe remaining portion 2 should be separated at a place other than the second section f ₂ as shown in FIG. 5, for example. You can also
However, since the straight pipe portions 1a and 2a other than the joint f are thin,
The padding portions 16 and 26 are formed to provide the tubular connecting portion 26a on the upper pipe remaining portion 2 side, and the connection expanding portion 16 on the song mouth side short pipe 1 side.
A is provided to secure the strength. Overlay 16,2
It is also possible to adopt a method in which the metal ring R or the like is wound to secure the strength in the same manner as in the intermediate joints 25 and 39 without having a thickness in 6. However, as shown in FIGS. 1 to 3, it is thicker and stronger in terms of strength when separated and formed at the point of the second section f ₂ near the mouth opening 11, and when the upper pipe A is connected to form the upper pipe A. It is more preferable because it is not known that they are connected due to the knot shape and the appearance is good.

In the shakuhachi of this embodiment, the tube hole 30 of the lower tube 3 has a shape as shown in FIG. That is, the tube hole 30 of the conventional lower tube 3 has a bulging portion K in the middle of the tube hole as shown in FIG. 6, whereas the lower tube 3 of the present embodiment has both end portions 3 thereof.
Both 1 and 39 gradually decrease in diameter from the hole diameters D ₁ and D ₂ of the tube hole 30 at the end points toward the central area of the tube hole of the lower pipe 3. The hole diameter gradually decreases from the hole diameter D ₁ of the connecting portion 39 with the upper pipe A side (more specifically, the upper pipe remaining portion 2) toward the central region of the lower pipe hole 30, and the distance Y from the connecting end 39. And the pore size reaches D ₃ (D ₁ > D ₃ ). Further, the hole diameter gradually decreases from the hole diameter D ₂ on the tube tail 31 side toward the central area of the tube hole, and reaches the hole diameter D ₃ at a point of the distance X from the tube tail 31 (D ₂ > D ₃ ). The upper pipe-side connecting portion 39 is formed with a draft that tapers from the inside of the pipe by an angle α, and a draft that tapers from the inside of the pipe by an angle β (β> α) on the pipe tail 31 side. Has been formed.
Since there is a tapered draft from the inside of the pipe to both ends of the lower pipe 3, it is easy to mold. The present inventor has found that even without providing the bulge portion K, a tone close to the original tone color of the shakuhachi can be produced only by providing draft angles α and β (β> α). In FIG. 4, the angles α and β are emphasized and drawn at a large angle for easy understanding. In addition, the lower pipe 3 in FIG. 4 reaches the confluence of the hole diameters D ₃ with a slope from both ends 31, 39, but only a certain range of the both ends 31, 39 extends from the end to the lower pipe 3. It is sufficient if the diameter of the hole gradually decreases toward the central area of the tube hole. A lower pipe having a constant hole diameter D and a predetermined length in the central region of the pipe hole 30 is also within the scope of the present invention.

The present embodiment is a shakuhachi in which the upper pipe A and the lower pipe 3 are separable at the splice points 31, 39.
Eliminating 1,39, separable as the mouthpiece side short pipe 1 at the section f near the mouthpiece 11 as a boundary, and the mouthpiece side short pipe 1 is a shakuhachi that is detachably attached to the remaining portion. You can also
The length of the singing mouth side short tube 1 is preferably in the range of 5 cm to 20 cm. If the length of the short pipe 1 on the singing mouth side is less than 5 cm, it becomes difficult to practice. On the other hand, if it exceeds 20 cm, it is inconvenient to carry and it is difficult for beginners such as elementary school students to make a sound, and it is more likely that they will be shunned at the beginning. Is.

The shakuhachi constructed in this manner is a short tube 1 on the singing mouth side.
Since the remaining part (or the upper tube remaining part 2) is formed separately, if the school side purchases the entire shakuhachi or the part except the mouthpiece side short tube 1, the students will first have the mouthpiece side short tube. You only need to purchase one. Since it is only the singing mouth side short pipe 1, it can be purchased at a low price. Since the mouthpiece side short pipe 1 is provided with a mouthpiece 11 for direct lip contact, each student who purchased can practice using his or her own mouthpiece 11. There is no need to purchase a mouthpiece or the like separately.

A tone color can be produced only by the singing mouth side short tube 1. Moreover, the shorter the tube, the easier it is to make sound, which is extremely useful for beginners. Furthermore, the singing mouth side short pipe 1 is originally a part of the shakuhachi, and the practice of the singing mouth side short pipe 1 is directly connected to the shakuhachi practice. You only have to go through the procedure of purchasing the whole shakuhachi when you get better, and you can do a set of expensive shopping at the beginner's stage, there is no end, and the entire expensive shopping is not wasted. Further, when the singing mouth side short pipe 1 is separated and formed at the node f close to the singing mouth 11 (for example, the second node f ₂ ), the connecting portions 14, 2 are formed by the thick portion of the node f.
The strength of 4 can be maintained. If the joints are separable, it is difficult to distinguish that they are connected by the joints f due to the unique shape of the joints when they are connected, which is also aesthetically superior.

In addition, the short mouth tube 1 is 1/3 of the whole shakuhachi
The length is about 1/4, and the cost can be reduced accordingly. If it is a shakuhachi made of synthetic resin, it can be offered at a lower price. If the singing mouth side short pipe 1 is made of synthetic resin, the selling price can be about several hundred yen. Furthermore, both ends 3 of the lower pipe 3
If both the pipes 1 and 39 have a structure in which the pipe hole 30 gradually decreases from its end point toward the pipe hole central region of the lower pipe 3, the pipe hole 30 has a draft. Therefore, since the shakuhachi can be easily manufactured by resin molding, the shakuhachi as a whole can be provided at a lower price. It is even more useful for the spread of shakuhachi.

The present invention is not limited to those shown in the above-mentioned embodiment, but can be variously modified within the scope of the present invention depending on the purpose and application. The shape, size, number, materials, etc. of the upper pipe A, the singing mouth side short pipe 1, the upper pipe remaining portion 2, the lower pipe 3, etc. can be appropriately selected according to the application. In the embodiment, the standard tube shakuhachi has been described, but of course, for example, a short tube or long tube type shakuhachi can be applied. Draft gradient α, β of the lower pipe 3
Can also be attached by post-processing after molding. The shape of the tubular connecting portion 24a and the connecting expanded diameter portion 14a does not matter, and the tubular connecting portion corresponding to the tubular connecting portion 24a is connected to the singing mouth side short pipe 1 to the upper pipe remaining portion 2. A connection expanded portion corresponding to the expanded portion 14a can be provided.

[0019]

As described above, the shakuhachi of the present invention has a structure in which the lower pipe can be easily molded and only the short pipe on the singing mouth side can be purchased, so that the elementary and junior high school students can easily purchase it at a low price. In addition, the shakuhachi can be practiced with only the short pipe on the singing mouth side.
