DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a unit type drum according to the present invention will be described with reference to the drawings. FIG. 1 is an overall perspective view of a unit-type drum according to the present invention. 2 is a cross-sectional view of a drum body of a unit-type drum according to claim 1 of the present invention, FIG. 3 is a cross-sectional view of a drum body of a unit-type drum according to claim 2 of the present invention, and FIG. It is a drum main part sectional view of a unit type drum concerning Claim 3 of an invention.
[0014]
The overall structure of the unit-type drum 100 of the present invention includes, for example, as shown in FIG. 1 or 2, an annular wall surface 2 that surrounds the outer edge of the circular bottom plate 1, and a through hole 3 in the center of the circular bottom plate 1. A perforated wooden body frame member 4, a metal leg member 5 that can be folded like a folding pipe chair to which the body frame member 4 is attached, and a body frame member 4 that can be freely attached to the body frame member 4. It has a structure having a drum surface member 9 in which a drum surface 8 made of a material such as cowhide, horseskin, synthetic leather, synthetic fiber cloth, carbon fiber cloth is stretched on a rigid ring-shaped frame body 7.
[0015]
The main body frame member 4 corresponds to a body portion of a Japanese drum, and the drum surface member 9 corresponds to a drum surface removable from the main body frame member 4. As shown in FIG. 2, the drum main body 10 composed of the main body frame member 4 and the drum surface member 9 is rotatably supported by the leg members 5 by fixing brackets 11 and 12 screwed to the back surface of the circular bottom plate 1. It is attached to the leg 5a so as to be freely attached to and detached from the collar 6 so as to be rotatable.
[0016]
Since the main body frame member 4 has a thickness of about 50 to 100 mm and a diameter of about 300 to 400 mm, when the leg member 5 is folded, it can be stored compactly as if it were a folding chair. In addition, if the through-hole 3 has a diameter that is 2/3 or more of the outer diameter of the main body frame member 4, the sound effect is obtained as a sound emitting hole with a rich volume and a good sound.
[0017]
The drum surface member 9 has a size just enough to fit in the main body frame member 4, and several lifting prevention rubbers 13 are arranged on the outer periphery in a state where the drum surface 8 is stretched on the ring-shaped frame body 7, and has a height. Several feet 14 of about 10 to 30 mm are arranged, and the drum surface member 9 is placed on the circular bottom plate 1 with a little space.
[0018]
It is obvious that the unit type drum 100 having the above structure is simple in configuration, can be manufactured at low cost, is lightweight, and is easy to carry and store.
[0019]
The leg member 5 in FIG. 1 has a shape similar to that of a folding chair, but its folding-free mechanism and shape can be designed as appropriate, and the height adjustment mechanism and position adjustment mechanism of the drum main body 10 to be attached are provided. It is also desirable to provide the leg member 5 separately.
[0020]
Next, in addition to the structure of the drum main body 10, the drum main body 20 shown in FIG. 3 is interposed between the circular bottom surface 1 of the main body frame member 4 and the drum surface member 9 from the through hole 3 of the circular bottom surface 1. In particular, a removable sound adjusting disk 22 provided with a small sound emitting hole 21 is inserted.
[0021]
If the sound adjusting disk 22 is made of wood having a thickness of, for example, about 5 mm and can be stored in the main body frame member 4, the sound emitting hole 21 is smaller than the through hole 3 in the circular bottom surface 1 of the main body frame member 4. For example, the diameter is 50 to 100 mm. By arranging various sound adjusting disks 22 having sound emitting holes 21 of different sizes, drums having various volumes and timbres can be produced.
[0022]
Next, the drum main body 30 shown in FIG. 4 is useful for practice, and is a circular plate that can be freely attached to the main body frame member 4 in place of the drum surface member 9 in the structure of the drum main body 10. In this structure, a practice drum surface member 29 is formed of elastic members 25 and 26 attached to the upper surface of 24.
[0023]
In the above structure, the through-hole 3 in the circular bottom surface 1 of the main body frame member 4 is completely closed by the circular plate 24 of the practice drum surface member 29, and even if the upper surface of the elastic member 26 is strongly hit with a bee, There is no sound and no drum sounds. However, the rebound when the elastic member 26 is hit with a bee is similar to the rebound in the case of a normal drum, and is suitable for practice. The elastic member 25 is a slightly hard sponge-like elastic member having a thickness of about 20 to 30 mm, and the elastic member 26 is preferably a rubber plate-like elastic member having a thickness of about 2 to 3 mm and rich in durability.
[0024]
As described above, the three drum main bodies 10, 20, and 30 have been described on the premise of the unit drum 100 as the unit drum 100. However, since the unit drum of the present invention is unitized, the main body frame member 4 In combination with the drum surface member in a timely manner, various forms can be achieved, and depending on the drum surface 8 used for the drum member, it is possible to apply not only a Japanese drum but also a Western drum.
[0025]
Needless to say, the unit-type drum 100 can be used not only for practice and education, but also for actual performance.
[0026]
【The invention's effect】
Since the unit-type drum according to the present invention is configured as described above,
(1) It can be folded and stored.
[0027]
(2) It is a unit type, and the tone color and volume can be changed by selecting the drum surface member.
[0028]
(3) The cost is much lower.
[0029]
(4) Suitable for music education at kindergartens and elementary and junior high schools.
[0030]
(5) It can be used for practice without sound.
