Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum, and particularly to provide a drum which is inexpensive and has excellent performance.

[0002]

2. Description of the Related Art Conventionally, a drum such as a Japanese drum or a Western drum in which a drum-like skin is stretched on a side end of a tubular body is composed of a single plate made by cutting out wood. However, it is not only difficult and complicated to manufacture, but also bulky and difficult to transport.

Further, since the body made of a single piece of wood is limited in the size and material of the wood and the number of pieces that can be taken from one piece of wood, the cost of the body becomes extremely high. there were.

Further, the body made of one plate of the wood is
There is a problem in that the quality of each material is different, and it is difficult to arrange the qualities so that the same tapping sound is produced.

Further, since the body made of a single piece of wood is made of wood which is a natural material, it is difficult to keep the quality constant and the tapping sound becomes inaccurate.

Further, the body made of one plate of the wood is
Not only is it difficult to obtain due to environmental issues and plant protection, but it is also becoming more difficult to use due to the higher price. Further, the body made of a single plate of wood has a problem that the tensile strength and the shear strength gradually decrease with the lapse of time, and the body becomes fragile and easily damaged.
Further, in such a body made of a single plate of wood, there is a problem in that the tapping sound may change depending on the temperature and the climate and an accurate sound may not be produced.

[0007]

[0015]

The present invention will now be described in detail with respect to specific embodiments with reference to the accompanying drawings.

1 to 4 show an embodiment of a drum according to the present invention.

The drum 1 according to this embodiment has a body 2 formed in a cylindrical shape, and drum surfaces 3 stretched on both side ends of the body 2.
It comprises an attachment frame 4 for stretching and mounting the body 3 on the body 2, and a fixture 5 for fixing the body 3 stretched on the body 2.

The body 2 is made of a material other than one piece of wood, and in this embodiment, it is made of a particle board which is a thick board material obtained by thermocompressing wood chips with a synthetic resin adhesive. And is formed into a hollow cylindrical shape having a constant diameter.

The drum surface 3 is made of animal leather and has a substantially circular shape.

Further, the drum surface 3 is attached to the body 2 by an attachment frame 4
It is stretched and attached at the same time, and is fixed through the fixing tool 5.

The attachment frame 4 is formed in an annular shape having a predetermined width and an inner diameter substantially the same as the outer diameter of the body 2, and a large number of connecting holes 4a penetrating in the axial direction are evenly formed over the entire circumference. Has been done.

Further, a large number of attachment plates 6 having a plurality of attachment holes 6a are connected to the open end of the attachment frame 4 at equal intervals by joining means such as welding.

Further, the fixing tool 5 comprises a locking tool 7 and a substrate 8 on which the locking tool 7 is locked. The substrate 8
Has a groove portion (U-shaped) in cross-section fixed to the body 2, and has a flat plate shape in which the pivotally-attached portions with the locking tool 7 face each other. Many are fixed in. The engaging member 7 is formed in a groove shape (U-shape) in cross section and is pivotally attached to the base plate 8 via a shaft 9 so as to be rotatable. Further, the rear end portion has the attaching plate. A locking portion 11 for locking 6 is formed in a bent shape, and by locking the mounting plate 6 and rotating the locking tool 7, the above-mentioned drum surface via the mounting frame 4. Tuning can be performed by adjusting the tension degree of 3.

Therefore, of the plurality of attachment holes 6a formed in the attachment plate 6, the attachment hole 6a at a position where the tension of the drum surface 3 is appropriate is fitted to the engaging portion 11. By stopping the rotation and fixing the locking tool 7 in rotation, the tension of the drum surface 3 can be adjusted through the attachment frame 4 to perform tuning.

At this time, since the drum body 2 is fixed directly to the drum body 2 in the related art, if it becomes necessary to tune the drum surface 3 due to a change with time, the drum surface 3 is once removed from the drum body 2 and the drum surface 3 is removed. It is necessary to adjust the tension and fix the drum surface 3 directly to the body 2 again to tune the drum surface 3. However, in the present invention, the fitting for engaging and locking the locking tool 7 is performed. Since it suffices to selectively lock the hole 6a at an appropriate position, the tuning of the drum surface 3 becomes simple and easy.

Next, a method of using the above embodiment will be described.

First, a substantially circular drum surface 3 is stretched over both ends of a cylindrical body 2, and the outer side of the drum surface 3 is attached to an attachment frame 4 formed in an annular shape having a predetermined width. It is attached via a connecting tool 4b such as a rivet.

Subsequently, the attachment holes 6a of the multiple attachment plates 6 connected to the attachment frame 4 are fitted and locked in the locking portions 11 so that the tension of the drum surface 3 becomes appropriate. To do.

Next, in a state in which the attachment plate 6 is fitted and locked to the locking portion 11 of the locking tool 7 which is rotatably pivoted to the base plate 8 via the shaft 9, the locking tool is engaged. By rotating and fixing 7 toward the end of the body 2, the drum surface 3 is attached via the attachment frame 4.
The drum surface 3 is attached to the body 2 in a state in which the tension of is adjusted.

Subsequently, the drum surface 3 is completed by mounting the drum surface 3 by hitting the drum surface 3 with a drumstick to check the tapping sound, adjusting the mounting position of the mounting plate 6 and tuning.

In this way, the attachment holes 6a to be fitted and retained on the retainers 7 are selectively retained at appropriate positions, and the attachment holes 6a are attached to the attachment plate 6. The attachment of the drum surface 3 is completed by adjusting the position and tuning.

Furthermore, after use, the drum surface 3 changes with time.
If the degree of tension changes, it is necessary to tune. In this case, the degree of tension of the drum surface 3 among the plurality of attachment holes 6a formed in the attachment plate 6 is The tension of the drum surface 3 is adjusted through the attachment frame 4 by fitting and locking the attachment hole 6a at an appropriate position to the locking portion 11 and rotationally fixing the locking tool 7. Then you can tune.

At this time, since the drum body 3 has been fixed directly to the drum body 2 in the past, if it is necessary to tune the drum surface 3 due to a change with time, the drum surface 3 is once removed from the body 2 and the drum surface 3 is removed. It is necessary to adjust the tension and fix the drum surface 3 directly to the body 2 again to tune the drum surface 3. However, in the present invention, the fitting for engaging and locking the locking tool 7 is performed. Since it suffices to selectively lock the hole 6a at an appropriate position, tuning of the drum surface 3 becomes simple and easy, and tuning is simple even when used for a long time.
You will always be able to make accurate sounds.

Next, the operation of the above embodiment will be described.
