[0002]

2. Description of the Related Art The steel pan is a percussion instrument made by a Trinidad and Tobago person from a drum (200 liters) in which oil is put, and is a musical instrument which is currently receiving much attention in Japan. This musical instrument is cut from the bottom of a drum can at a predetermined height to form a cylinder whose upper end is closed. The closed part is tapped from above to form a mortar-shaped recess, and 29 musical scales are placed in the recess. It was manufactured by putting.

Inserting a scale into the mortar-shaped recess is as follows.
This was done by forming as low a region as the number of each scale by a hitting manufacturing method and tuning with a tuner.

[0004]

However, the work of inserting the scale is very troublesome, and since this work requires a long time, the manufacturing cost becomes very high, and this musical instrument becomes very expensive. was there. Also a drum
The fact that only one unit can be manufactured, and the waste oil treatment and cutting of drums are troublesome, are also factors that make this instrument expensive.

The inventor of the present invention thought to mass-produce this steel pan, but since the tone color subtly changes depending on the material (soft iron, steel plate) of the drum can, the conventional manufacturing method mass-produces a steel pan of constant quality. That turned out to be very difficult.

[0006] In addition, by making a purchaser such as children perform the work of adding a scale that takes a very long time,
It was conceived to provide steel pan at low cost, but it was found that it is extremely difficult for children to add scales by the conventional manufacturing method because the steel drum has a large thickness.

The present invention is intended to solve such a problem, and an object of the present invention is to provide a steel pan capable of mass-producing a constant quality steel pan.

The present invention also enables purchasers, such as children, to perform work such as adding scales.
The object is to provide a steel pan that can be obtained at low cost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, which is a pan-shaped body (mortar-shaped body) 1 having an arc-shaped cross section and a short cylindrical body 2.
And a strip ring 3 attached to the outer periphery of the welded portion of the pot-shaped body 1 and the short cylindrical body 2 and fixed by welding.

The pot-shaped body 1, the short cylindrical body 2 and the strip-shaped ring 3 are made of metal, and preferably made of metal such as steel plate, stainless steel, titanium and copper.

The pan-shaped body 1 having an arcuate cross section is preferably formed by pressing a disc 4 as shown in FIG.
By doing so, after welding the outer peripheral edge of the arcuate pot-shaped body 1 and the upper end of the short cylindrical body 2 as shown in FIG. 3, the band-shaped ring 3 is attached to the welded portion and welded, which is then used by children. If sold to children, the children will find that the curved portion 5 has as many low areas 6 as there are musical scales.
This is because it suffices to form the by a hitting manufacturing method. However, after the outer peripheral edge of the disc 4 is welded and fixed to the upper end of the short cylindrical body 2 and the strip ring 3 is attached and welded to the outer periphery of the welded portion,
The disc 4 may be pressed. Also, purchasers such as children may hit the disc 4 to form the curved portion.

The short cylindrical body 2 and the strip-shaped ring 3 may be formed by forming an elongated plate body into a ring shape and connecting both ends by welding to form a ring shape. Of course, the short cylindrical body 2 and the strip ring 3 may be directly molded.

As shown in FIG. 3, the upper end 8 of the pot-shaped body is
A ring-shaped band portion 8 is provided close to or in close contact with the upper end portion 7 of the cylindrical body 2. By doing so, it becomes easy to distinguish the sound of each scale from the sound. Ring-shaped strip 8
To provide, the pan-shaped body upper end portion 8 and the cylindrical body upper end portion 7,
It may be tapped or pressed so that it is close or close.

The short cylindrical body 2 is preferably formed higher than the depth of the pan-shaped body 1. By forming the short cylindrical body 2 higher than the depth of the pot-shaped body 1, the short cylindrical body 2 can be placed horizontally on a table or the like as shown in FIG. The higher the short cylindrical body 2 is formed, the lower the sound becomes. Therefore, the ratio is
It should be set according to the desired sound quality.

The thickness of the cylindrical body 2 and the metallic pot-shaped body 1 is
0.6 to 0.8 mm, and the outer diameter of the cylindrical body 2 is 20 to 4
It is preferably 0 cm. In this way, even a child can easily form a scale by the impact manufacturing method.

In the above-mentioned embodiment, the curved portion 5 has a curved shape,
Eight scales are formed: Mi, Fa, So, La, Si, and Do. To form the scale, it is preferable to strike a hammer to form a low region 6, and to tune (tune) the sound with a tuner, and strike with a hammer from the front surface or the back surface to obtain the desired sound. The scale itself can be formed in a conventional manner. Also, 29 scales can be formed as in the conventional case. In this case, the outer diameter of the cylindrical body 2 is preferably larger than 40 cm.

The steel pan formed as described above can be used as a percussion instrument by suspending it on columns 9 and 9'and striking a scale with a rod 10 as shown in FIG. 4, for example. Since the steel pan of the present invention can be made smaller than the conventional one, it can be used by suspending it from the neck by connecting an appropriate cord.

FIG. 5 shows another embodiment of the present invention, showing an example in which a flange 11 is formed on the upper end of the metallic pot-shaped body 1. By forming the flange in this way,
This is preferable because the difference in scale becomes clear and the scale is easily formed. In addition, the sound is transmitted to the flange to cause a lingering sound. In the figure, reference numeral 12 is an opening, and a string is passed through this opening to support the pillars 9 as shown in FIG.
It can be hung on 9'or hung from the neck.

Also, when the outer flange 11 is tapped, a tone in the scale of the region 6 near the flange is produced. Therefore,
The sounds of de, le, mi, fa, so, la, and si in FIG. 5 can be obtained by striking the flange 11 without striking the area 6.
The scale of this area 6 can be produced.

In order to manufacture a steel pan as shown in FIG. 5, a metal disk and a metal cylinder having a diameter smaller than that of the same disk are welded together, and a disk portion of the disk in contact with the cylinder is formed. It suffices to bend it into a pot shape with an arcuate cross section, form as low a region as the number of scales on the inner surface of the curved portion by a striking method to insert the scales, and form the non-curved portion of the disc into a flange.

Further, a metal pot-shaped body having an arcuate cross-section with a flange formed at the upper end is formed in advance, and the arcuate recess is fitted and welded to the metal cylindrical body, and the number of each scale is provided on the inner surface of the pot-shaped curved portion. It is also possible to form a low region only by a hitting method and add a scale.

In order to form a metal pan-shaped body having an arcuate cross-section with a flange formed at the upper end, it is sufficient to hold the flange portion and press it. Further, in order to process the cylindrical body into a brim after welding, it may be hit with a hammer or the like from above as in the conventional case.

According to the present invention, since it is possible to form a metal plate without using a drum can, it is possible to mass produce steel pans of the same quality.

Further, according to the present invention, the thickness and size of the scale can be easily formed by children, so that a purchaser such as children can perform the step of inserting the scale. be able to. Further, the step of welding the disc to the cylindrical body and then processing it into a mortar shape may be performed by a purchaser such as children.

Therefore, for example, if a class for making steel pans is opened by parents and children to make steel pans, it is suitable for children's sound sense education, and expensive steel pans can be obtained at extremely low cost. be able to.

[0035]

According to the present invention, steel pans of constant quality can be mass-produced, and purchasers such as children can perform the work of adding scales, so expensive steel pans can be made extremely inexpensive. It has a great effect that it can be obtained.
