Description

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

Conventionally, drums such as Hass drums, pastum toms, tom toms, snare drums, etc. have a head holding hoop that presses the outer periphery of the drum head (drum membrane), and the bolt receiver attached to the drum body is tightened by the hoop on a metal fitting. The structure is such that the drum head is tightened by the lm to tension the drum head.

That is, to explain a conventional drum by taking a snare drum as an example, in Figure 1, the symbol 1 is a cylindrical drum body with both ends open, 2 is a drum head stretched across both ends of the drum body 1, and 3 is a drum head attached to the drum body 1. The drum head 2 is attached to the outer peripheral edge 2a of the drum using a head presser hoop, and the bolt receiver attached to the outer circumferential surface of the drum body l is attached to the metal fitting 4. To tighten the hoop, tighten the head presser hoop 3 with the bolt 5. I'm starting to get nervous. The metal fitting 4 of the delt receiver is a pipe-shaped nut 8 held by a pace member 7 attached to the drum body 1 by a fixing bolt 6, and the hoop tightening bolt 5 is attached to the above-mentioned groove-shaped nut 8. When the bolt 5 is tightened, the head holding hoop 3 is tightened to the metal fitting 4 side, and the drum head 2 is tightened. In addition,?
The bolt receiver comes in two types: a double type with a pipe-shaped nut on both sides as shown in the figure, and a single type with a pipe-shaped nut on only one side. is mainly used for thin double-head drums with a small drum body depth and drum heads at both ends of the drum body.

Also, single-shaped day? The metal fittings are used for various types of drums where the depth of the drum body exceeds a certain level, for middle rams, and for single-head drums where the drum head is installed only at one end of the drum body and the other end is left open. In the case of a double-head drum using metal fittings for single-type bolt receivers, the metal fittings of the two bolt receivers are attached back to back in the lengthwise 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, when tightening the hoop to tension the drum head, the bolt receiver is a metal fitting attached to the drum body. This had the disadvantage that the resonance effect of the drum body deteriorated.

This invention was made in view of the above-mentioned circumstances, and its purpose is to eliminate the metal fittings for the bolt receiver from the drum body, thereby maintaining a high resonance effect of the drum body, thereby achieving good sound quality. Our aim is to provide drums that can be obtained.

That is, in this invention, at one end of a cylindrical drum body whose both ends are open, a required number of rib-shaped nuts are arranged along the length of the drum body so as to surround the outer periphery of the drum body with a gap. Stack the rings and separate them.In the case of a double drum, attach the drum head to the other end of the drum body (the end of the drum body on the side where the rings are not stacked), and tighten the holding hoop by inserting the bolt into the tip of the pipe-shaped nut. For both head drums, tighten the drum heads on the other end of the drum body and the outer end of the ring, and tighten the bolts on the pipe-shaped end of the ring. This is a configuration in which the proximal end and K tJ are aligned.

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, reference numeral 11 is a cylindrical drum body with both ends 1 open, 12 is a drum head attached to both ends of the drum body 1, and 3 is an outer peripheral edge J2 of the drum head 12.
The upper striking drum head 12 (hereinafter referred to as the upper head) is attached to the drum body 11 by a head holding hoop that presses the
It is attached to the upper end of the frame as shown in Fig. 3. Also, 14
is a metal +441J ring having the same diameter as the drum body 11, and this ring 4 is attached to the drum body 1 as shown in FIG.
The lower drum head 12 (hereinafter referred to as the lower head) is attached to the outer end (lower end) of the cage ring 14. A ring-shaped cushioning material 15 made of soft synthetic resin, rubber, or Fefurt is sandwiched between the abutting surfaces of the ring 14 and the drum body 11.

The ring 14 has a required number (10 nuts in this embodiment) of vertical pipe-shaped nuts 16 arranged along the length of the drum body 1 around the ring 14 so as to surround the outer periphery of the drum body 11 with a gap. The glossy nut 16 is threaded over the entire length of the inner surface of the pipe, and an external thread for attaching a ring is provided on the outer periphery of the base end of the nut 16. There is. and,
The glossy nut 16 is attached to an overhanging portion 17 which is provided at equal intervals on the outer periphery of the ring 14 on the side where it abuts against the drum body no. The base end of the nut is attached by screwing together the proximal end of the nut, and the lower end of the arm 16 is attached to the protruding part 17.
It is exposed on the underside of the. Note that 18 is a nut that is screwed onto the base end of the /4'-shaped nut 16 and tightened to the upper surface of the overhang J7;
Attachment of an elongated nut to No. 7 is used to increase the strength. Further, the overhang portion 17 has its upper surface slightly lower than the lower end position of the drum body 11.
), and the inner end surface of this protrusion 17h is used as a positioning surface that contacts the outer circumferential surface of the lower end of the drum body 11. Reference numeral 9 denotes a pair of accessory parts mounts that are provided on both sides of the ring 14, avoiding the overhang 17, and these accessory parts mounts 19 are attached to the drum body II at a position that does not touch the drum body 11. It is shaped like a V so that it stands up on the outside. Reference numeral 20 denotes an accessory mounting hole provided in the accessory mounting plate 19.

As shown in FIG. 3, the presser hoop 13 of the upper head 12 is connected to the pipe-shaped nut 16 by screwing a bolt 21 into the tip of the pipe-shaped nut 16. This hoop is tightened with bolt 21.
By tightening, the upper head 12 is tightened slightly toward the tube-shaped nut 16. Note that the ring 1
4 is pressed against the drum body 1 by a reaction force VC that tensions the upper head 12.

Also, a lower head 12 stretched on the outer end of the ring J4.
As shown in FIG. 3, the presser hoop J3 is connected to the base pin-shaped nut 16 by screwing its tightening bolt 21 into the base end of the pipe-shaped nut 16. Tightening is done by tightening the bolt 21 to the side of the vibrator nut 16, thereby tensioning the lower head 2.

On the other hand, in a snare drum, the valley line 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 ray tensioning tool, and this sound ray tensioning tool 22 includes a sound ray tensioning member 24 that is moved up and down by rotation of the operating lever 23, and a sound ray tensioning member 24. and a sound ray tension adjustment knob 25 for adjusting the position of the
A retaining string 27a secured to one end of the valley line 26 is secured to the sound ray tensioning member 24 by a retaining plate 28 and a set screw 29 through a notch 1.7a provided in the head retaining hoop J3.

Incidentally, since the sound ray tensioning device 22 has been widely used in the past, a detailed explanation thereof will be omitted. The sound ray tensioning device 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 1.

Further, as shown in FIG.
The ring 14 is connected to the other accessory mounting plate 19 by fixing it to the other accessory mounting plate 19 through the notch 1.9a of the ring 14 with setscrews 3 and 32.

Since the seats 21 and 21 are screwed together, there is no need to attach metal fittings to the drum body for the selt receiver like in the conventional drum body, and therefore the resonance effect of the drum body 1 is not deteriorated. In addition, in conventional snare drums, the valley line tensioning device was attached to the drum body, and the retaining string at the other end of the valley line was also fixed to the drum body, which also worsened the resonance effect of the drum body. However, in the snare drum of the above embodiment, the drum body 1 is attached to the ring 14.
A sound ray tensioning device 2 is attached to an accessory mounting plate 19 provided apart from 1.

In addition, in the above embodiment, the sound ray tensioning device 22 is attached and the valley line 2 is
6, an accessory mounting plate J9 is provided on the ring 14, but instead of providing this accessory mounting plate 19 on the ring 4, an accessory mounting plate J9 as shown in FIGS. 6 and 7 is installed. A fixture 33 may also be used. That is, this accessory parts mounting tool 33 is used by being attached between the adjacent pipe-shaped nuts 16, 16 disposed on the ring 14, and this accessory parts mounting tool is used. 33 has a semi-circular glossy bracket part 35 that holds half the circumference of the pipe-shaped nut 16 at both ends, and a component attachment hole 36 in the center part.
A component support plate 34 is provided with a component support plate 34, and a pipe holder is tightened with screws 37Vc at both ends of the component support plate 34, and a pipe-shaped part 35 is formed between the component support plate 34 and a part 35. The component supporting plate 34 supports a sound ray tensioning device and the like.

Furthermore, although the snare drum has been described in the above embodiment, the configuration of the above embodiment can be applied as is to both head drums. FIG. 8 shows the bust 9 ram A and tom tom B having the configuration of the above embodiment, and the support legs 39 of the pass drum A are connected to the pipes via the accessory fittings 33 shown in FIGS. 6 and 7. In this case, it is supported by 16. Also, tom-tom B set on pass drum A
The tom holder C, which supports the tom holder C, is held by a bracket 40 fixed to an accessory fitting 33 attached to the pipe-shaped nut 16 of the hestrum A, and the tom-tam B is held by an accessory attachment 33 attached to the pipe-shaped nut 16 of the hestrum A. A tom holder mounting bracket 41 is attached to the component mounting tool 33 so that the tom holder C is supported.

FIG. 9 shows a second embodiment of the present invention, in which the drum head 12 is stretched only on the end of the body on the side where the rings 14 are not overlapped, and the presser hoop 13 is tightened by bolts 2.
The ring 14 is screwed onto the tip side of a pipe-shaped nut 16 provided on the ring 14. Note that the single-head drum of this embodiment does not have a drum head attached to the ring 14 side;
Since the other configurations are the same as those of the first embodiment, the same reference numerals are attached to the drawings and the explanation thereof will be omitted. However, in this single-head drum, since the hoop tightening bolt is not screwed onto the base end of the pipe-shaped nut 160, the groove-shaped nut 16 is not A? An internal thread may be provided only on the tip side of the tube.

10 and 11 show a third embodiment of the present invention, in which the /'P
A fixed nut paste that can be attached to the ring 14.
The structure is made up of a joint pipe J6h and a replaceable joint pipe J6b which is screwed to the tip of this fixed pipe pipe 16m. Different lengths are prepared and replaced depending on the depth of the drum body 11. That is, in this embodiment, the drum cylinder 1 is replaced with one with a different depth, and the 011 record i4
By replacing the nut 16b with one of a different length and making the length of the nut 16- correspond to the depth of the drum body 1, a drum with a shallow body depth as shown in FIG. It is possible to freely configure a drum with a deep body as shown in FIG. Note that the connecting pipe 16b of this embodiment is similar to i4 of the first and second embodiments.
It is also possible to use it by threadingly connecting it to the tip of the isometric nut 16.

Since the drum of the present invention has the above-described structure, the bolt receiver does not have a metal fitting from the drum body, so that the resonance effect of the drum body can be maintained high, and therefore good sound quality can be obtained.
