Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snare drum having a snappy.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 8, a snare drum (small drum) 1 of this type is made of natural leather, resin film (eg, polyester resin, etc.) Front and back side drum heads 3A and 3B (polycarbonate resin or the like) (the front side drum head is a reference numeral only) are supported and tensioned by the head support tensioning mechanism 4 with a uniform tension, and a snappy is applied to the back side head surface. 5 is arranged, and the snappy 5 is selectively brought into contact with the back side head surface by the backing mechanism 6, so that the vibration of the back side drum head 3B is transmitted to the snappy 5 to bring about a light tone such as a flip sound peculiar to an instrument. A special sound effect called a so-called tabling effect is obtained. A portion A corresponding to the back-end mechanism 6 at the opening edge on the sound ray side of the body 2 is recessed so as to be lower than other portions by being subjected to bed-shaped processing as shown in FIG.
This has a undulation on the back side head surface, and snappy 5
This is to improve the contact with the head surface during use.
The head support tension mechanism 4 generally holds the peripheral portions of the front surface side and back surface side drum heads 3A and 3B, respectively.
A pair of head frames 7 (see FIG. 7) slidably fitted to the outer peripheral surface of the body, and a pair of tightening frames 8 also fitted to the outer peripheral surface of the body 2 to press the head frames 7; It is composed of a plurality of lugs 9 fixed to the outer peripheral surface of the main body 2 and bolts 10 for connecting each tightening frame 8 to the lugs 9.
When the tightening frame 8 is moved in the axial direction by the rotation operation of 0, the pressing force of the tightening frame 8 against the head frame 7 changes, and the tension of the drum heads 3A and 3B, in other words, the tone color of the drum 1 is adjusted. The snappy 5 is a thin (eg 0.5 mmφ) sound ray 5a made of an intestinal string or a coiled metal string.
A plurality of (e.g., 20) are stretched in parallel, and the tension thereof is variably set by the backing mechanism 6.
The back-end mechanism 6 for contacting and separating the snappy 5 from the back side head surface includes a snappy plate 11 that holds the end of the snappy 5, a locking arm 12 attached to the outer peripheral surface of the body 2, and a rocking arm 12 that has a body. The main body 2 includes a slider 13 movably arranged in the axial direction, to which the snappy plate 11 is connected, a lever 14 for moving the slider 13 up and down, an adjusting knob 15 for variably setting the tension of the snappy 5. Since the head support tensioning mechanism 4 and the backing mechanism 6 are well known in the art (Japanese Utility Model Publication No. 57-25266, Japanese Utility Model Publication No. 63-39755, etc.), further description is omitted.

In such a snare drum 1, the snappy 5 is separated from the back side head surface during normal playing, and in this state, a drum sound as an ordinary drum is emitted. The slider 13 is operated by operating the lever 14.
When the snappy plate 11 is pulled down, the snappy 5 also lowers and comes into contact with the back surface side head surface, and when the front surface side head surface is hit in this state, the special sound effect of "para-para" is obtained as described above.

[0004] Here, when the tension applied to the snappy 5 is changed, the timbre is slightly different, and when the tension is increased, a good snare sound with a sharp cut is obtained at the center of the sound ray, but no sound is produced at the end of the sound ray. Disappear. As shown in FIG. 9, the force F applied to the snappy 5 by the recess 17 formed corresponding to each back-end machine 6 at the sound ray side opening end of the body 2 is directed downward (toward the front side drum head). This is caused by the fact that the sound ray ends are strongly brought into close contact with the front surface peripheral portion of the back side drum head 3B, and the sound ray central portion is brought into proper contact with the head surface, instead of the force. On the other hand, if the tension is weakened, the adhesion between the end of the sound ray and the back side drum head 3B becomes weaker, and the adhesion becomes weaker at the center of the sound ray, so that vibration easily occurs at the end of the sound ray. A snare sound can be obtained, but it vibrates too much in the central part of the resonation line and sounds too much, resulting in a choppy sound.

[0005]

As described above, in the conventional snare drum of this type, since the snappy 5 is stretched in the diameter direction of the drum, the tension and the central portion of the sound ray are affected by adjusting the tension. The degree of contact or close contact with the head surface at the end of the wire is different, and if the tension is increased, a good snare sound with good cut can be obtained at the center of the sound line, but no sound is produced at the end of the sound line and the tension is weakened. Then, while the delicate and good snare sound can be obtained at the end of the sound ray, there is a problem that the center of the sound ray sounds too much and the sound is not sharp.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to produce a sharp snare sound and a delicate snare sound at the same time. It is to provide a snare drum capable of obtaining an attractive special sound effect different from that of the drum.

[0007]

In order to achieve the above object, the invention according to claim 1 is such that a front side drum head and a back side drum head are respectively stretched on each opening end surface of a body, and a back side head surface is provided. On the other hand, in the snare drum in which the snappies are arranged so that they can come into contact with and separate from each other, the snappies are composed of a plurality of ring-shaped sound rays arranged in concentric circles having different diameters. According to a second aspect of the present invention, in the first aspect of the invention, the snappy sound ray is joined and fixed to at least three or more snappy plates arranged at predetermined intervals in the circumferential direction. Characterize. According to a third aspect of the present invention, a front surface side drum head and a rear surface side drum head that are respectively stretched on the respective open end surfaces of the trunk body,
In a snare drum provided with a snappy arranged on the back side head surface and a backen mechanism for selectively bringing this snappy into contact with the back side head surface, the snappies have different diameters and are arranged concentrically. The ring-shaped sound ray comprises a plurality of ring-like sound rays, and at least three or more snappy plates arranged at predetermined intervals in the circumferential direction of the sound ray, and joined and fixed to each sound ray. A plurality of holding members which are arranged on the outer peripheral surface of the body so as to be movable in the axial direction of the body and hold the respective snappy plates, and a plurality of holding members which are rotatably fitted on the outer surface of the body. And a connecting wheel that moves in the axial direction of the trunk main body in conjunction with each other. The invention according to claim 4 is the invention according to claim 3, characterized in that a recess is formed at a position corresponding to each holding member of the backen mechanism at the snappy side opening edge of the trunk body. .
According to a fifth aspect of the present invention, in the third or fourth aspect of the present invention, each holding member of the backing mechanism and the connecting wheel are connected by a toggle mechanism.

[0008]

In the invention described in claims 1 and 2, the snappy is composed of a plurality of ring-shaped reverberation lines having different diameters and arranged concentrically, and makes contact with the back side head surface in the circumferential direction. To do. Therefore, since it does not come into contact with the center of the head surface, even when the center of the head surface is struck, it does not squeal too much, and a proper tabling effect can be obtained. The snappy plate holds at least three or more places in the circumferential direction of the sound ray. In the invention according to claim 3, the backken mechanism holds each snappy plate and presses it against the head surface. Since the sound ray itself is ring-shaped, tension cannot be applied, but when the snappy plate is pressed against the head surface, the sound ray comes into contact with the head surface due to the waviness of the head surface, and tension is applied. Therefore, the end portion of the sound ray (the sound ray portion fixed to the snappy plate) and the central portion of the sound ray (the sound ray portion between the snappy plates) come into contact with the head surface with a proper contact pressure. As a result, a delicate snare sound is obtained at the end of the sound ray fixed to the snappy plate, and a sharp snare sound is obtained at the center of the sound ray. In the inventions according to claims 3 and 5, when the connecting wheel is rotated, all the holding members operate simultaneously to bring the snappy into contact with or away from the back side head surface. In the invention according to claim 5, the toggle mechanism remarkably doubles the rotational operation force of the connecting wheel and transmits it to the holding member.

It should be noted that, in the figure, the same components as those in FIGS. In these figures,
The snappy side opening edge of the trunk body 2, that is, the opening edge 2a on which the back side drum head 3B is stretched is subjected to bed shape processing every 90 °, whereby four recesses 2 are formed.
1 (FIG. 1) are formed at equal intervals in the circumferential direction. For this reason, the backside drum head 3B is stretched in a circumferentially undulating manner such that the portion corresponding to the recesses 21 is low and the space between the recesses 21 is high (in the drum usage state, the opposite is true). A backen mechanism 23 for selectively bringing the snappy 22 into contact with the back surface side drum head 3B is provided at a position corresponding to each of the recesses 21 on the outer peripheral surface of the trunk body 2.

The snappy 22 is composed of, for example, 16 sound rays 24 which are ring-shaped and are concentrically arranged with different diameters. As the sound ray 24, as shown in FIG. 2, for example, a diameter D is about 0.5 mmφ, and a metal string (piano wire) having a plated surface has a pitch P1 of about 3.5 mm and a diameter D1 of 2.0 mmφ. A spirally wound one is used. The sound ray 24 is fixed to the surface of the four snappy plates 11 arranged at equal intervals in the circumferential direction facing the rear drum head 3B with solder 26 at an interval P2 of about 3 mm. There is. The maximum radius of the sound ray 24 is 153 mm, and the minimum radius is 10.
It is about 8 mm.

4 to 7, the backing mechanism 2 is shown.
3 includes a base plate 30 closely fixed to a position corresponding to the recess 21 on the outer peripheral surface of the body 2, and a holding member 31 for holding the snappy plate 11 from below is attached to the base plate 30. It is arranged so that it can slide in any direction. A guide portion 32 that guides and holds the holding member 31 is integrally provided on the surface of the base plate 30. A screw mounting portion 31A made of a cylindrical body with both ends open is integrally provided at the center of the front surface of the holding member 31, and the adjusting screw 34 is only rotated on the screw mounting portion 31A from the side opposite to the back side drum head 3B. It is allowed. Further, the holding member 31 has a snare clamp fitting 36. The snare clamp metal fitting 36 is formed in an L shape in a side view, and is bent substantially at a right angle in the center direction of the body 2 from the base 36a parallel to the outer peripheral surface of the body 2 and the tip of the base 36a. A holding portion 36b for holding the snappy plate 11 from below, and the adjusting screw 34 is provided in a screw hole formed on the upper surface of the base portion 36a.
The male screw part of is screwed. Therefore, the adjusting screw 3
When 4 is rotated, the snare clamp metal fitting 36 is moved in the vertical direction, whereby the distance between the back side drum head 3B and the snappy 22 is finely adjusted. The rotation of the snare clamp fitting 36 at this time is prevented by the recess 37 formed at the lower end of the holding member 31. The holding part 36
The felt 38 is fixed to the upper surface of b. In addition, in this embodiment, since the snappy 22 is simply placed on the holding portion 36b, it may move in the radial direction. In that case, the snappy plate 11 may be fixed on the holding portion 36b by an appropriate means. Also,
A sliding groove 39 into which the guide portion 32 is fitted is formed on the back surface side of the holding member 31.

A base plate 3 is formed on the outer peripheral surface of the body 2
A connecting wheel 41 for vertically moving all the holding members 31 at once is loosely fitted above 0. The connecting wheel 41 is rotatably held by a plurality of rollers 42 arranged on the outer peripheral surface of the body 2. The roller 42 is a roller shaft 43.
Is rotatably disposed on the lower end surface 41a and supports the lower end surface 41a of the connecting wheel 41. Further, four connecting plates 44 are provided on the outer peripheral surface of the connecting wheel 41 so as to correspond to each backing mechanism 23. The connecting plate 44 is formed in an inverted L shape when viewed from the front, has an arcuate cam surface 44A on the lower surface side, and is connected to the holding member 31 of each backing mechanism 23 via a toggle mechanism 45. The toggle mechanism 45 has one end pivotally supported by a first link lever 47, one end of which is pivotally supported by a pin 46 provided on the back surface of the holding member 31, and one end thereof is pivotally supported by a fixing pin 48 protrudingly provided on the surface of the base plate 30. , A second link lever 50 having the other end connected to the lower end of the guide plate 44 via a pin 49, and a first link lever 47.
The other end of is connected to the intermediate portion of the second link lever 50 via a pin 51. The first link lever 47 is shorter than the second link lever 50 and intersects at an angle of approximately 90 °. The pins 46 and 48 are located apart from each other in the sliding direction of the holding member 31.

In the snare drum having such a structure, the snappy 22 is separated from the back side head surface during normal performance. At this time, the holding member 31
It is set and held at the lowest position shown in FIGS. 5 and 7.
In this state, when the snappy 22 is brought into contact with the back side head surface and a special sound effect called "para-para" is obtained, the connecting ring 41 may be manually rotated by a predetermined angle in the arrow X direction in FIG. That is, since the rotation of the rotary wheel 41 is transmitted to the holding member 31 via the toggle mechanism 45, the holding member 31 moves upward along the base plate 30. The rotation of the connecting wheel 41 at this time is accompanied by upward movement due to the toggle mechanism 45, but when the connecting wheel 41 rotates, the cam surface 44A
Contact the roller 42, the connecting wheel 41
Never leave. Further, the toggle mechanism 45 significantly doubles the rotational force of the connecting wheel 41 and transmits it to the holding member 31. When the holding member 31 moves upward, the snare clamp metal fitting 36 also rises together with the holding member 31 and the snappy 2
2 is pressed against the back side head surface with a predetermined pressure. Therefore, when the front side head surface is struck in this state, a special sound effect called a flip is obtained.

In this case, the sound ray 24 itself is not tensioned, but when the felt 38 presses the snappy plate 11 against the head surface, the pressing force works in combination with the waviness shape of the head surface. Tension is generated in the direction of the front side drum head. Therefore, the end portion of the sound ray near the snappy plate 11 and the central portion of the sound ray between the adjacent snappy plates 11 can be satisfactorily compared with the conventional linear snappy shown in FIG. 8 at a desired pressure with respect to the head surface. Can be pressed.

When the connecting wheel 41 rotates by a predetermined angle, the connecting plate 4
The vertical portion of 4 abuts the roller 42 and is prevented from further rotation. At the stop position of the connecting wheel 41, the toggle mechanism 45 is locked by moving the pin 51 to the right side of FIG.
Prevent the return of 1. Further, when the contact pressure of the snappy 22 is adjusted, the adjustment screw 34 may be rotationally operated to move and adjust the snare clamp metal fitting 36 in the vertical direction.

It should be noted that in the above embodiment, the circumferential direction 4 of the sound ray 24 is
The case where the locations are fixed to the snappy plate 11 has been described, but the present invention is not limited to this, and the sound ray 24 can be stably held at three or more locations. In that case, the sound radiation side opening edge 2 of the body 2
The number of recesses 21 formed in a is set to the snappy plate 11
It should match the number of.

[0017]

As described above, in the snare drum according to the present invention, since the snappy is composed of a plurality of concentric ring-shaped sound rays, the sound rays do not pass through the center of the head surface, Even if it hits the center of the surface, it does not squeal too much, and a moderate tabling effect is obtained. Further, both the fixed end portion and the central portion of the sound ray can be pressed against the head surface with a good contact pressure, and a delicate snare sound can be obtained when the outer peripheral portion of the head surface is hit. Therefore, in a single adjustment state, a sharp snare sound and a delicate snare sound due to the end of the sound ray can be simultaneously obtained, and a snare sound different from the conventional snare drum can be obtained. Further, in the present invention, since the connecting wheel and the holding member are connected by the toggle mechanism, the rotational force of the connecting wheel can be increased. For this reason, the snappy can be brought into contact with the back side head surface at a required pressure despite the small operating force.
