Description

[Detailed description of the invention] This invention relates to drums.

Conventionally, bass drum, bass tom tom, tom tom,
A drum such as a snare drum is constructed such that a head holding hoop that presses the outer periphery of the drum head (drum membrane) is tightened by a hoop tightening bolt to a bolt receiving fitting attached to the drum body to tension the drum head.

That is, to explain a conventional drum using a snare drum as an example, in FIG. This is a head holding hoop that presses down the outer peripheral edge 2a of the drum head, and the drum head 2 is tensioned by tightening the head holding hoop 3 with a hoop tightening bolt 5 to a bolt receiving metal fitting 4 attached to the outer peripheral surface of the drum body 1. It is becoming more and more common. The bolt receiving fitting 4 has a pipe-shaped nut 8 held on a base member 7 that is attached to the drum body 1 by a fixing bolt 6, and the hoop tightening bolt 5 is screwed into the tip side of the pipe-shaped nut 8. When the hoop tightening bolt 5 is tightened, the head holding hoop 3 is tightened against the bolt receiving metal fitting 4, and the drum head 2 is tightened. In addition, the bolt receiving metal fittings are double type with a pipe nut 8 on both sides as shown in the figure, and single type with a pipe nut 8 on only one side.Double type bolt receiving metal fittings are mainly It is used for thin double-head drums with a small drum body depth and drum heads at both ends of the drum body. In addition, single-type bolt receivers are used for various types of double-head drums where the depth of the drum body exceeds a certain level, and for single-head drums in which a drum head is provided at only one end of the drum body and the other end is left open. In the case of a double-head drum using single-type bolt receiving metal fittings, two bolt receiving metal fittings are attached back to back in the length direction (depth direction) of the drum body.

By the way, since the sound quality of a drum is generally greatly influenced by the resonance effect of the drum body, a drum body with good resonance is used.

However, as mentioned above, in conventional drums, the hoop tightening bolts that tension the drum head are attached to the drum body, so the bolt receivers have a large effect on the resonance of the drum body, and as a result, the drum It had the disadvantage that the resonance effect of the body deteriorated.

This invention was made in view of the above-mentioned actual situation, and its purpose is to eliminate the bolt receiving metal fittings from the drum body and to maintain a high resonance effect of the drum body, thereby improving sound quality. Our aim is to provide drums that can be obtained.

That is, in the present invention, a required number of pipe-shaped nuts extending along the length of the drum body are arranged around one end of a cylindrical drum body whose both ends are open so as to surround the outer periphery of the drum body with a gap between them. For one-head drums, put the drum head on the other end of the drum body (the end of the drum body on the side where the rings are not overlapped), and screw the tightening bolt of the presser hoop onto the tip side of the pipe-shaped nut. In both head drums, a drum head was attached to the other end of the drum body and the outer end of the ring, and the tightening bolt of the presser hoop of each drum was screwed into the tip side and the base end side of the pipe-shaped nut. It is of composition.

Embodiments of the present invention will be described below with reference to the drawings.

2 to 5 show a first embodiment of the present invention, and the drum in this embodiment is a snare drum.

In FIG. 2, numeral 11 is a cylindrical drum body with both ends open, 12 is a drum head stretched over both ends of the drum body 11, and 13 is a head holding hoop that presses the outer peripheral edge 12a of the drum head 12. A striking drum head 12 (hereinafter referred to as the upper head) is attached to the upper end of the drum body 11 as shown in FIG. Further, 14 is a metal ring having approximately the same diameter as the drum body 11, and this ring 14 is attached to the drum body 11 as shown in FIG.
The lower drum head 12 (hereinafter referred to as the lower head) is stretched over the outer end (lower end) of this ring 14. Note that the ring 14
A ring-shaped cushion material 15 made of soft synthetic resin, rubber, or felt is held between the abutting surfaces of the drum body 11 and the drum body 11 .

The ring 14 has a drum body 11 around it.
A required number of vertical pipe-shaped nuts 16 (in this embodiment, 10 nuts) are arranged so as to surround the outer circumference of the drum body 11 with a gap, and the pipe-shaped nuts 16 are arranged on the inner surface of the pipe. The pipe-like nut 16 is threaded over its entire length, and an external thread for attaching a ring is provided on the outer periphery of the base end of the pipe-shaped nut 16. The pipe-shaped nut 16 is connected to the drum body 1 of the ring 14.
It is attached by screwing the base end of a pipe-shaped nut into a screw hole provided in the overhanging portion 17 on the overhanging portion 17 that is provided at equal intervals on the outer periphery of the side that butts against the overhanging portion 1. The lower end of this pipe-shaped nut 16 is exposed on the lower surface of the overhang 17. In addition,
Reference numeral 18 denotes a nut that is screwed onto the base end of the pipe-shaped nut 16 and tightened to the upper surface of the overhang 17, and this nut 18 strengthens the attachment strength of the pipe-shaped nut 16 to the overhang 17. is used for. Further, the projecting portion 17 has a shape in which its upper surface projects slightly higher than the lower end position of the drum body 11, and this projecting portion 17
The inner end surface of a is used as a positioning surface that contacts the outer peripheral surface of the lower end portion of the drum barrel 11. Reference numeral 19 denotes a pair of accessory mounting plates that are provided at both ends of the ring 14 to avoid the projecting portion 17, and these accessory mounting plates 19 are mounted on the outside of the drum body 11 at a position that does not touch the drum body 11. It is formed to stand up. Reference numeral 20 denotes an accessory mounting hole provided in the accessory mounting plate 19.

The presser hoop 13 of the upper head 12 is
As shown in FIG. 3, the pipe-shaped nut 16 is connected by threading the tightening bolt 21 onto the tip end side of the pipe-shaped nut 16.
By tightening this hoop tightening bolt 21, it is tightened to the pipe-shaped nut 16 side, and the upper head 12 is tightened.
It makes me nervous. The ring 14 is pressed against the drum body 11 by a reaction force that tensions the upper head 12. Further, the holding hoop 13 of the lower head 12 stretched over the outer end of the ring 14 has its tightening bolt 21 screwed into the base end side of the pipe-shaped nut 16, as shown in FIG. Therefore, it is connected to the pipe-shaped nut 16, and by tightening the hoop tightening bolt 21, it is tightened to the pipe-shaped nut 16 side, thereby tensioning the lower head 12.

On the other hand, in a snare drum, the acoustic wire stretched on the lower surface of the lower head is stretched in the following manner. That is, in FIG. 4, reference numeral 22 indicates a sound line tensioning tool, and this sound line tensioning tool 22 includes a sound line tensioning member 24 that is moved up and down by the rotation of the operating lever 23, and a sound line tensioning member 24 that is moved up and down by the rotation of the operating lever 23. It has a sound wire tension adjustment knob 25 for adjusting the position of the member 24, and a retaining string 27a fixed to one end of the sound wire 26 passes through a notch 13a provided in the head presser hoop 13 to tighten the sound wire tension member 24. Press plate 28 and set screw 29
It is fastened by. Incidentally, since the sound line tensioning tool 22 has been widely used in the past, detailed explanation thereof will be omitted. The sound wire tensioning tool 22 is fixed to one of a pair of attachment plates 19 provided on the ring 14 with a set screw 30, and is installed apart from the drum body 11. Further, the other end of the sound wire 26 is attached to a retaining string 27a fixed to the end of the sound wire, as shown in FIG.
is connected to the other accessory mounting plate 19 of the ring 14 through the notch 13a of the head presser hoop 13 with a set screw 31 and a nut 32.

In the above-mentioned snare drum, the ring 14 stacked on the lower end of the drum body 11 is attached to the ring 14.
The presser hoops 13, 1 of the upper and lower drum heads 12, 12 are attached to the pipe-shaped nuts 16 provided apart from the drum heads 12, 1.
Since the hoop tightening bolts 21, 21 for tightening the drums 1 and 3 are screwed together, there is no need to attach bolt receiving fittings to the drum body unlike conventional drums, and therefore the resonance effect of the drum body 11 will not be deteriorated. In addition, in conventional snare drums, the tensioning device for the sound wire was attached to the drum body, and the retaining string at the other end of the sound wire was also fixed to the drum body, which also worsened the resonance effect of the drum body. However, in the snare drum body of the above embodiment, the sound wire tensioner 22 and the stopper 27a at the other end of the sound wire are attached to the accessory mounting plate 19 provided on the ring 14 apart from the drum string 11. Because it is, the sound line tension device 2
It is also possible to eliminate the problem of deterioration of the resonance effect of the drum body 11 due to the attachment of the drum body 2 and the like.

In the above embodiment, an accessory mounting plate 19 is provided on the ring 14 in order to attach the sound wire tensioner 22 and fasten the sound wire 26, but instead of providing this accessory mounting plate 19 on the ring 14, Alternatively, an accessory mounting tool 33 as shown in FIGS. 6 and 7 may be used. That is, this accessory mounting tool 33
is used by being attached between the adjacent pipe-shaped nuts 16, 16 disposed on the ring 14, and this accessory attachment tool 33 has a half circumference of the pipe-shaped nut 16 at both ends. a component support plate 34 having a semicircular pipe receiving portion 35 for holding the pipe and having a component mounting hole 36 in the center;
The component support plate 34 is provided with a pipe holding plate 38 which is tightened with screws 37 at both ends to clamp and fix the pipe-shaped nut 16 between it and the pipe receiving portion 35 of the component support plate 34. The support plate 34 supports a sound line tensioner or the like.

Furthermore, although the snare drum has been described in the above embodiment, the structure of the above embodiment can be applied as is to both head drums. FIG. 8 shows a bass drum A and a tom tom B having the configuration of the above embodiment. It is supported by a shaped nut 16. Further, a tom holder C that supports tom tom B set on bass drum A is held by a bracket 40 fixed to an accessory attachment 33 attached to a pipe-shaped nut 16 of bass drum A, and tom tom B is The tom holder mounting bracket 4 is attached to the accessory parts mounting tool 33 attached to the pipe-shaped nut 16.
1 is attached and supported by tom holder C.

FIG. 9 shows a second embodiment of the present invention, in which the drum head 12 is stretched only on the body end on the side where the ring 14 is not overlapped, and the tightening bolt 21 of the presser hoop 13 is attached to the ring 14. It is screwed onto the distal end side of a provided pipe-shaped nut 16. Note that the single head drum of this embodiment has a ring 14.
Since the other configuration is the same as the first embodiment except that the drum head is not attached to the side, the same reference numerals are given in the drawings and the explanation thereof will be omitted. However, in this one-head drum, since the hoop tightening bolt is not screwed into the base end of the pipe-shaped nut 16, the pipe-shaped nut 16 may be provided with an internal thread only on the distal end side of the pipe.

10 and 11 show a third embodiment of the present invention, in which a pipe-shaped nut 16 provided on a ring 14 is connected to a fixed pipe 16a attached to the ring 14, and a fixed pipe 16a attached to the ring 14. 16a and a replaceable connecting pipe 16b that is screwed to the tip of the drum body 16a. Various lengths of the connecting pipe 16b are available, and the length can be changed according to the depth of the drum body 11. be exchanged.
That is, in this embodiment, the drum body 11 is replaced with one having a different depth, and the connecting pipe 16 is
b can be replaced with one of a different length and the length of the pipe-shaped nut 16 can be made to match the depth of the drum body 11, thereby making it possible to create a drum with a shallow body depth as shown in FIG. As shown in the figure, it is possible to freely construct a drum with a deep body. The connecting pipe 16b of this embodiment can also be used by being screwed onto the tip of the pipe-shaped nut 16 of the first and second embodiments.

Since the drum of the present invention has the above-described structure, it is possible to eliminate the bolt receiving metal fittings from the drum body, thereby maintaining a high resonance effect of the drum body, and thus achieving good sound quality.
