Description

Technical Field

[0001] The present invention relates to a bass drum pad.

Background Art

[0002] Patent Document 1 discloses an electronic bass drum that is played using a striking mechanism including a beater that swings by a player's stepping operation. The electronic bass drum includes a head having a striking surface and a stand that supports the head.

[0003] On the outer peripheral portion of the head, a plurality of attachment portions projecting outward on the outer peripheral side are provided. A head connector formed by a bolt extending in a direction orthogonal to the striking surface of the head penetrates each attachment portion. The head connector is screwed into a lug provided at a position facing the attachment portion on the outer peripheral portion of the head. A cylindrical damper member that is disposed between the attachment portion and the lug and into which the head connector is inserted is attached to a part of the plurality of head connectors.

[0004] The stand includes a plate-shaped stand body that stands upright in the vertical direction and extends along the striking surface of the head. The stand body has a through hole through which the head connector penetrates and into which the damper member fits. The diameter of the through hole is larger than the diameter of the head connector and substantially the same as the diameter of the damper member.

[0005] When the damper member fits into the through hole, the head is elastically supported with respect to the stand. Therefore, when the head is struck by the beater, the head moves forward in the striking direction of the beater with respect to the stand, and the damper member is compressed in the axial direction. Thereby, the impact acting on the head at the time of striking the head is absorbed.

Patent Document 1

[0007] The diameter of the through-hole in the stand body is larger than the diameter of the head connector and approximately the same as the diameter of the damper member. In other words, the damper member is interposed between the outer surface of the head connector and the inner surface of the through-hole. Therefore, the head connector can move inside the through-hole while compressing the damper member. As a result, when the head is struck, the head may move not only in the axial direction of the damper member but also in directions different from that axial direction. For example, if the beater strikes the head away from the center of the striking surface, or if two distant points on the striking surface are struck by a twin pedal, the damper member is compressed while the head is tilted, which may cause the head to vibrate. In particular, when the head is struck rapidly by the beater, the vibration of the head becomes more pronounced. In this case, it may cause discomfort to the performer. [Means for solving the problem]

[0008] This document describes a bass drum pad design that addresses the above-mentioned problems. [Aspect 1] A bass drum pad played using a pedal device equipped with a beater that swings when pressed by a performer, comprising: a support body; a striking portion including a pad body that is struck by the beater and is movably supported with respect to the support body; a guide mechanism that guides the striking portion to move in a guide direction relative to the support body when the pad body is struck; and an impact absorbing portion disposed between the striking portion and the support body for absorbing the impact acting on the striking portion.

[0009] According to the above configuration, when the pad body is struck by the beater, the struck portion moves relative to the support in the direction guided by the guide mechanism. Therefore, it is possible to suppress the movement of the struck portion in a direction different from the guide direction when the pad body is struck by the beater. The impact of the struck portion that moves in the guide direction is absorbed by the shock absorption portion. As a result, the sensation felt by the performer when the pad body is struck by the beater tends to be uniform. Therefore, it is possible to suppress causing discomfort to the performer.

[0010] Furthermore, the shock-absorbing section is positioned between the striking surface and the support structure. This suppresses the generation of contact noise between the striking surface and the support structure when the beater strikes the pad body. Consequently, the noise reduction during bass drum pad use can be improved.

[0011] [Aspect 2] The bass drum pad according to [Aspect 1], further comprising a facing portion that faces the struck portion in the direction opposite to the guide direction, wherein the struck portion is biased toward the facing portion by the impact absorbing portion.

[0012] According to the above configuration, the striking portion is biased toward the opposing portion by the shock-absorbing portion. Therefore, the striking portion, which moves in the guide direction as the pad body is struck, is moved in the opposite direction to the guide direction by the biasing force of the shock-absorbing portion and pressed toward the opposing portion. This positions the striking portion when the pad body is not being struck. Consequently, it is possible to suppress variations in the performer's feel when the pad body is repeatedly struck by the beater.

[0013] [Aspect 3] The bass drum pad according to [Aspect 1] or [Aspect 2], wherein the guide mechanism includes a support shaft that rotatably supports the striking portion about an axis extending horizontally with respect to the support, and the support shaft guides the striking portion to move in the guide direction, which is one side of the rotational direction about the axis.

[0014] With the above configuration, the guide mechanism can be implemented with a simpler structure compared to a configuration in which the guide mechanism guides the part to be struck in the horizontal direction. [Aspect 4] The bass drum pad according to [Aspect 3], wherein the striking portion comprises an arm that extends from the support shaft in a direction intersecting the axis and to which the pad body is fixed.

[0015] According to the above configuration, the pad body is struck by the oscillating beater, causing the struck part to rotate around the support axis. Here, the direction of the beater's strike is the tangential direction during rotation due to the beater's oscillating motion. For a performer to get a feeling close to playing a bass drum when playing a bass drum pad, it is preferable that the pad body moves in the direction of the beater's strike at the moment it is struck. According to the above configuration, by lengthening the arm extending from the support axis, the radius of rotation of the pad body is increased, so that the range in which the tangential direction of the pad body during rotation generally aligns with the direction of the beater's strike can be increased. As a result, the direction of movement of the pad body can be approximated to the direction of the beater's strike, allowing the performer to get a feeling close to playing a bass drum.

[0016] [Aspect 5] The bass drum pad according to [Aspect 4], wherein the striking portion is provided with a stopper that extends from the arm and rotates together with the arm, and the stopper is configured to compress the impact absorbing portion as the striking portion rotates about the axis.

[0017] According to the above configuration, when the part being struck rotates due to the impact of the pad body, the stopper compresses the shock-absorbing part. This suppresses the transmission of vibrations caused by the impact of the pad body to the mounting surface of the pedal device via the support.

[0018] Furthermore, with the above configuration, even if the beater's striking position varies, the impact is uniformly converted into the rotational movement of the arm, thus suppressing variations in the contact position between the stopper and the shock absorber. Therefore, it is possible to suppress causing discomfort to the performer.

[0019] [Aspect 6] The bass drum pad according to [Aspect 5], wherein the stopper faces the upper surface of the support and the striking portion rotates about the axis to approach the upper surface of the support, and the shock absorbing portion is positioned between the stopper and the upper surface of the support.

[0020] With the above configuration, when the part being struck rotates due to the impact of the pad body, the stopper compresses the shock-absorbing part from above. This makes it easier for the impact transmitted from the beater to the part being struck to escape downwards. Therefore, compared to a configuration in which the shock-absorbing part is compressed horizontally when struck by the beater, the bass drum pad is less likely to move horizontally.

[0021] Furthermore, with the above configuration, the stopper approaches the upper surface of the support as the striking part rotates around the axis of the support shaft. Therefore, compared to a configuration in which the stopper extends from the arm along the support shaft, for example, it is possible to suppress an increase in the size of the bass drum pad in the direction along the support shaft.

[0022] [Aspect 7] The bass drum pad according to [Aspect 6], wherein the shock absorbing portion is a first shock absorbing portion, the support has a facing portion above the stopper that faces the stopper, and the bass drum pad comprises a second shock absorbing portion disposed between the facing portion and the stopper.

[0023] According to the above configuration, a second shock-absorbing part is positioned between the stopper and the opposing part located above it. Therefore, when the arm rotates in the opposite direction to the guide direction due to the restoring force of the compressed first shock-absorbing part acting on the stopper, the stopper is pressed against the second shock-absorbing part. This positions the part to be struck when the pad body is not being struck. Consequently, it is possible to suppress variations in the performer's feel when the pad body is repeatedly struck by the beater.

[0024] Moreover, according to the above configuration, it is possible to suppress the generation of contact noise between the stopper and the opposing portion when the arm rotates in the direction opposite to the guiding direction. [Aspect 8] The shock absorbing portion is formed of rubber, and the shock absorbing portion is a hollow cylindrical shape having a central axis extending in the horizontal direction, the bass drum pad according to any one of [Aspect 5] to [Aspect 7].

[0025] The magnitude of the elastic force generated by compressing the rubber depends on the hardness of the rubber. However, when there is variation in the hardness of the rubber, the magnitude of the elastic force generated by compressing the rubber also varies.

[0026] In this regard, according to the above configuration, the shock absorbing portion is formed of rubber and is a hollow cylindrical shape. Therefore, in addition to the elastic force generated by compressing the rubber, an elastic force generated by the rubber deforming to fill the space of the hollow portion is applied to the shock absorbing portion. The magnitude of the elastic force generated by the rubber deforming depends on the shape of the rubber. Thereby, even when there is variation in the hardness of the rubber, it becomes easier to ensure the elastic force required for the shock absorbing portion.

[0027] [Aspect 9] The shock absorbing portion is formed of rubber, the bass drum pad according to any one of [Aspect 1] to [Aspect 7]. According to the above configuration, the shock absorbing portion can be embodied with a simple configuration.

[0028] [Aspect 10] The bass drum pad is an electronic bass drum pad provided with a vibration sensor for detecting vibration of the pad body, the bass drum pad according to any one of [Aspect 1] to [Aspect 9].

[0029] According to the above configuration, the bass drum pad can be applied as an electronic bass drum pad. Also, when the struck portion moves not only in the guiding direction but also in a direction different from the guiding direction during striking by the beater, there is a possibility that the detection accuracy of the vibration sensor may decrease.

[0030] In this regard, the above configuration allows the guide mechanism to prevent the part being struck from moving in a direction different from the guide direction when struck by the beater. Therefore, a decrease in the detection accuracy of the vibration sensor can be suppressed.

[0031] [Aspect 11] A bass drum pad played using a pedal device equipped with a beater that swings when pressed by a performer, comprising a support body, a part to be struck supported by the support body and including a pad body that is struck by the beater, and a bracket configured to be attachable to a support column of a stand that supports a percussion instrument other than the bass drum pad, wherein the support body has an extension portion extending toward the bracket and a clamped portion that is clamped from above and below by the clamp of the pedal device, the bracket has a support portion that supports the extension portion from below, and the bass drum pad is configured to be separated from the mounting surface of the pedal device by the extension portion being supported from below by the support portion and the clamped portion being clamped by the clamp.

[0032] According to the above configuration, the extension is supported by the support portion of the bracket attached to the stand's support column, and the clamped portion is held in place by the clamp, thereby raising the bass drum pad away from the mounting surface. This suppresses the transmission of vibrations from the pad itself when struck to the mounting surface, making it less likely for the performer to feel vibrations. Therefore, it is possible to reduce any discomfort for the performer.

[0033] Furthermore, because the bass drum pad is raised away from the mounting surface, contact noise between the bass drum pad and the mounting surface during the beater's strike of the pad can be suppressed. Therefore, the quietness of the bass drum pad during striking can be improved.

[0034] [Aspect 12] The bass drum pad according to [Aspect 11], wherein the extension portion has a restricting portion that faces the bracket on the opposite side of the support column with respect to the bracket and restricts the movement of the support in the direction toward the support column, and a protruding portion that protrudes from the restricting portion toward the bracket, and the support portion supports the protruding portion from below.

[0035] According to the above configuration, with the protruding part supported by the support part, the restricting part faces the bracket from the opposite side of the support column. Therefore, the impact of the pad body striking the bass drum is prevented from causing the bass drum pad to move closer to the support column. This suppresses changes in the relative position between the bass drum pad and the percussion instrument. In addition, it eliminates the need to provide a separate structure for fixing the bass drum pad to the mounting surface.

[0036] [Aspect 13] The bass drum pad according to [Aspect 11] or [Aspect 12], wherein the bracket has a pressing portion that presses the extension portion from above. With the above configuration, the extension is held down from above by the retaining part, which prevents the extension from lifting away from the bracket due to the impact when the pad body is struck. Therefore, it is possible to suppress changes in the relative position between the bass drum pad and the stand.

[0037] [Aspect 14] A bass drum pad according to any one of [Aspect 11] to [Aspect 13], wherein a cushioning member is attached to the portion of the extension that contacts the bracket.

[0038] With the above configuration, it is possible to suppress the generation of contact noise between the extension and the bracket when the pad body is struck. [Aspect 15] The bass drum pad according to any one of [Aspect 11] to [Aspect 14], wherein the bracket is configured to change the mounting position in the longitudinal direction of the support column.

[0039] According to the above configuration, the height position of the bass drum pad from the mounting surface can be changed by changing the mounting position of the bracket in the longitudinal direction of the support column. This allows the clamp of the pedal device to grip the clamped portion even if the height position of the pedal device changes due to the placement of a vibration-damping member between the pedal device and the mounting surface. Furthermore, even if multiple types of pedal devices with different clamp height positions are used, the clamp of the pedal device can grip the clamped portion. Therefore, the versatility of the bass drum pad can be increased. [Effects of the Invention]

[0040] According to the present invention, it is possible to suppress the feeling of discomfort to the performer. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0042] The following describes one embodiment in which a bass drum pad is incorporated as a bass drum pad in an electronic drum set, with reference to Figures 1 to 10. As shown in Figure 1, the electronic drum set 10 comprises a stand 11, a bass drum pad 12, a snare drum pad 13, a floor tom pad 14a, a first tom pad 14b, a second tom pad 14c, a hi-hat cymbal pad 15a, a first cymbal pad 15b, and a second cymbal pad 15c. The stand 11 is mounted on the mounting surface FL (see Figure 8(a)). Each pad is supported by the stand 11. The bass drum pad 12 is an example of an "electronic bass drum pad".

[0043] The electronic drum set 10 includes a sound source device 16 that produces sound based on the output signals of vibration sensors provided on each pad. The sound source device 16 is mounted on a stand 11. The sound source device 16 is connected to the vibration sensors of each pad by cables (not shown).

[0044] The pads, excluding the bass drum pad 12, are played by the performer striking them with a stick (not shown). The bass drum pad 12 is played by a pedal device 17 equipped with a beater 17a that oscillates in response to the performer's foot operation. The hi-hat cymbal pad 15a changes in tone when struck depending on whether or not the performer operates the hi-hat pedal 18.

[0045] (12 bass drum pad configuration) As shown in Figure 2, the bass drum pad 12 comprises a support 20, a striking part 30, a guide mechanism 50, a cushioning member 60, and a bracket 70. The striking part 30 includes the pad body 31 that is struck by the beater 17a. The striking part 30 is supported so as to be movable, more specifically, rotatable, relative to the support 20. The guide mechanism 50 guides the striking part 30 to move in the guide direction relative to the support 20 when the pad body 31 is struck. The cushioning member 60 is positioned between the striking part 30 and the support 20 and absorbs the impact acting on the striking part 30. The bracket 70 connects the support 20 to the support column 11a of the stand 11. As shown in Figure 1, the support column 11a supports the first tom pad 14b and the second tom pad 14c, which are percussion instruments different from the bass drum pad 12.

[0046] In the following explanation, the directions extending along the X, Y, and Z axes shown in some of the drawings will be referred to as the X-axis direction, Y-axis direction, and Z-axis direction, respectively. The X-axis direction, Y-axis direction, and Z-axis direction are orthogonal to each other. The Y-axis direction is the direction in which the pedal device 17 and the bass drum pad 12 face each other. The Z-axis direction is the vertical direction. Furthermore, with the bass drum pad 12 as the reference point, the direction away from the pedal device 17 in the Y-axis direction will be described as forward, and the direction approaching the pedal device 17 in the Y-axis direction will be described as backward.

[0047] (Configuration of the support 20) As shown in Figure 3, the support 20 has a base portion 21, a pair of support walls 23, and an extension portion 24.

[0048] The base portion 21 is a flat plate with the Z-axis direction as the thickness direction. The base portion 21 has a rectangular through hole 21a that penetrates the base portion 21 in the Z-axis direction, and a pair of first slits 21b that are spaced apart from each other in the X-axis direction. Each first slit 21b extends forward from the front edge of the through hole 21a.

[0049] The rear end of the base portion 21 is provided with a clamped portion 22 that is held in place from above and below by the clamp 17b (see Figure 8(a)) of the pedal device 17. The clamped portion 22 has a rib 22a that protrudes upward to reinforce the rear end of the base portion 21.

[0050] The pair of support walls 23 protrude upward from both ends of the base portion 21 in the X-axis direction and face each other in the X-axis direction. Each support wall 23 extends in the Y-axis direction. As shown in Figures 2 and 4, the extension portion 24 extends from the front end of the base portion 21 toward the bracket 70.

[0051] The extension portion 24 has a restricting portion 25 and a protruding portion 26. The restricting portion 25 protrudes upward in the Z-axis direction from the front end of the base portion 21. The protruding portion 26 protrudes toward the bracket 70 in the Y-axis direction from the upper end of the restricting portion 25. The protruding portion 26 is supported from below by the bracket 70.

[0052] The restricting section 25 is located on the opposite side of the support column 11a in the Y-axis direction, across the bracket 70, that is, at the rear, and restricts the movement of the support body 20 in the direction toward the support column 11a.

[0053] As shown in Figure 4, the projection 26 has a first portion 27 and a second portion 28. The first portion 27 extends forward from the upper end of the restricting portion 25. The second portion 28 extends inclined relative to the first portion 27, positioned lower as it extends forward from the front end of the first portion 27. As shown in Figure 3, the width of the second portion 28 in the X-axis direction is smaller than the width of the first portion 27 in the X-axis direction.

[0054] The base portion 21 has an opposing portion 29 that faces the stopper 37, which will be described later, above the stopper 37. The opposing portion 29 is formed by cutting and bending a part of the restricting portion 25 in the Y-axis direction on the side opposite to the protruding portion 26, i.e., towards the rear. The opposing portion 29 extends from the restricting portion 25 parallel to the base portion 21. The opposing portion 29 has a second slit 29a that extends forward from the rear end edge of the opposing portion 29. The second slit 29a is located between a pair of first slits 21b when viewed from the Z-axis direction.

[0055] As shown in Figures 4 and 5, a cushioning member 80 is attached to the portion of the extension 24 that contacts the bracket 70 using an adhesive (not shown). The cushioning member 80 is, for example, a sheet of felt. The cushioning member 80 covers the front and rear surfaces of the upper end of the regulating portion 25, as well as the upper and lower surfaces of the first portion 27.

[0056] As shown in Figure 3, the cushioning member 80 has an insertion hole 80a into which the protruding portion 26 is inserted. The cushioning member 80 is attached to the extension portion 24 by folding it so as to cover the restricting portion 25 and the first portion 27 with the protruding portion 26 inserted into the insertion hole 80a.

[0057] (Configuration of the part that is hit 30) The impact-receiving part 30 comprises a pad body 31, a pair of arms 36, and a stopper 37.

[0058] The pad body 31 comprises an elastic body 32 having a striking surface 32a that is struck by the performer, and a case 33 that houses the elastic body 32. The elastic body 32 is disc-shaped. The elastic body 32 includes, for example, a sponge and a mesh member provided on the surface of the sponge. The case 33 has an opening that exposes the striking surface 32a. The bottom wall of the case 33 is provided with mounting parts 34 to which a pair of arms 36 are fixed (see Figure 8(a)). The striking part 30 is supported by the support 20 in a position where the striking surface 32a is approximately perpendicular to the Y-axis direction.

[0059] The pair of arms 36 are fixed to the mounting portion 34 and the pair of support walls 23 from both sides in the X-axis direction. The pair of arms 36 extend in a straight line parallel to each other. The upper ends of the pair of arms 36 are fixed to the mounting portion 34 by two bolts 40 that are aligned along the length of the arms 36 and pass through the pair of arms 36 and the mounting portion 34, and by two nuts 41 attached to the two bolts 40. Each bolt 40 is inserted into a pair of cylindrical collars 42 that pass through the pair of arms 36 and are inserted into the mounting portion 34. In other words, a pair of collars 42 are interposed between each bolt 40 and the pair of arms 36.

[0060] The bolt 40 is made of a metal material. The collar 42 is made of a resin material. The collar 42 has the function of preventing the generation of contact noise between the bolt 40 and the arm 36.

[0061] The lower ends of the pair of arms 36 are rotatably supported by a pair of support walls 23 by a support shaft 51, which will be described later. The pair of arms 36 extend in a direction intersecting the support shaft 51, or more specifically, in a direction perpendicular to the support shaft 51.

[0062] The stopper 37 extends from and rotates with the pair of arms 36. The stopper 37 has a pair of fixed parts 38 and a push plate part 39. The pair of fixed parts 38 are each fixed to the pair of arms 36 by a plurality of screws 43. The pair of fixed parts 38 extend forward from the pair of arms 36. The push plate part 39 connects the front ends of the pair of fixed parts 38. The push plate part 39 is a flat plate with the Z-axis direction as its thickness direction. The push plate part 39 faces the upper surface of the base part 21. A mounting hole 39a is provided at the front end of the push plate part 39, which penetrates the push plate part 39 in the Z-axis direction.

[0063] The pressing plate portion 39 is configured to move closer to and further away from the upper surface of the base portion 21 as the striking portion 30 rotates around the support shaft 51. As shown in Figure 8(a), the impacted part 30 is equipped with a vibration sensor 35 that detects vibrations of the pad body 31. The vibration sensor 35 is located inside the case 33, between the bottom wall of the case 33 and the elastic body 32. More specifically, the vibration sensor 35 detects vibrations of the elastic body 32 when it is struck, and outputs a signal to the sound source device 16 corresponding to the magnitude of the vibrations.

[0064] (Configuration of the guidance mechanism 50) As shown in Figure 3, the guide mechanism 50 includes a support shaft 51 that rotatably supports the striking portion 30 about an axis A extending in the X-axis direction relative to the support body 20. The support shaft 51 is a bolt that rotatably supports the lower ends of a pair of arms 36 relative to the support body 20.

[0065] The support shaft 51 allows the impacted portion 30 to move to both sides in the circumferential direction around axis A, while restricting the movement of the impacted portion 30 in directions different from those sides in the circumferential direction. Therefore, the support shaft 51 guides the impacted portion 30 to move in the guide direction, which is one side of the rotational direction around axis A. In this embodiment, the guide direction is the front side in the rotational direction of the impacted portion 30 struck by the beater 17a.

[0066] The guide mechanism 50 comprises a pair of collars 52 and a nut 53. Each collar 52 passes through the arm 36 and the support wall 23. Each collar 52 also passes through a washer 54 positioned between the arm 36 and the support wall 23. The support shaft 51 is inserted into the pair of arms 36, the pair of washers 54, and the pair of support walls 23. A nut 53 is attached to the tip of the support shaft 51.

[0067] When the part to be struck 30 rotates around the axis A of the support shaft 51, the pair of arms 36 slide against the pair of collars 52. Therefore, the support shaft 51 does not rotate when the part to be struck 30 rotates.

[0068] The support shaft 51 is made of a metal material. Each collar 52 and each washer 54 is made of a resin material. Each collar 52 has the function of preventing the generation of contact noise between the support shaft 51 and the arm 36. Each washer 54 has the function of preventing the generation of contact noise between the arm 36 and the support wall 23.

[0069] (Composition of cushioning member 60) The cushion member 60 has a first shock-absorbing section 61, a second shock-absorbing section 62, a connecting section 63, a pair of first support protrusions 64, and a second support protrusion 65. The first shock-absorbing section 61, the second shock-absorbing section 62, the connecting section 63, the pair of first support protrusions 64, and the second support protrusions 65 are integrally formed from rubber.

[0070] The first shock-absorbing section 61 is a hollow cylindrical shape having a central axis A1 extending in the X-axis direction. The central axis A1 of the first shock-absorbing section 61 is parallel to the axis A of the support shaft 51. The first shock-absorbing section 61 is positioned between the lower surface of the stopper 37 and the upper surface of the base section 21.

[0071] The second shock-absorbing section 62 is a hollow cylindrical shape having a central axis A2 extending in the X-axis direction. The central axis A2 of the second shock-absorbing section 62 is parallel to the central axis A1 of the first shock-absorbing section 61. The second shock-absorbing section 62 is positioned between the upper surface of the stopper 37 and the lower surface of the opposing section 29. The length of the second shock-absorbing section 62 in the X-axis direction is shorter than the length of the first shock-absorbing section 61 in the X-axis direction. The wall thickness of the second shock-absorbing section 62 is smaller than the wall thickness of the first shock-absorbing section 61.

[0072] The connecting portion 63 connects the upper part of the first shock absorbing portion 61 and the lower part of the second shock absorbing portion 62. The connecting portion 63 is located in the center of the first shock absorbing portion 61 in the X-axis direction. The width of the connecting portion 63 in the X-axis direction is the same as the length of the second shock absorbing portion 62 in the X-axis direction. The connecting portion 63 is positioned inside the mounting hole 39a of the pressing plate portion 39. By compressing the second shock absorbing portion 62 and inserting it into the mounting hole 39a, the connecting portion 63 is positioned inside the mounting hole 39a. This allows the cushion member 60 to be attached to the stopper 37.

[0073] A pair of first support protrusions 64 project downward from the lower part of the first shock absorbing section 61 in the X-axis direction, spaced apart from each other. The pair of first support protrusions 64 are each engaged with a pair of first slits 21b. In this way, the first shock absorbing section 61 is supported by the base section 21.

[0074] The second support projection 65 protrudes upward from the upper part of the second shock-absorbing section 62. The second support projection 65 is engaged with the second slit 29a. This supports the second shock-absorbing section 62 against the opposing section 29.

[0075] (Configuration of bracket 70) As shown in Figures 6 and 7, the bracket 70 has a base 71, a pair of clamping parts 72, and a fastening part 73. The pair of clamping parts 72 extend forward from the base 71 and clamp the support column 11a. The fastening part 73 tightens the pair of clamping parts 72.

[0076] As shown in Figure 7, the pair of clamping portions 72 form a circular holding hole 72a for holding the support column 11a and a slit 72b connected to the holding hole 72a. The slit 72b extends along the entire Z-axis direction of the bracket 70.

[0077] The clamping portion 73 includes a bolt 74 that passes through a pair of clamping portions 72 in the X-axis direction, and a nut 75 embedded in one of the pair of clamping portions 72. The clamping portion 73 can change the amount of tightening of the support column 11a by the pair of clamping portions 72 by changing the amount the bolt 74 is screwed into the nut 75.

[0078] The bracket 70 is configured to be attachable to the support column 11a by tightening a pair of clamping portions 72 with a fastening portion 73. The bracket 70 is also configured to allow the mounting position of the bracket 70 in the longitudinal direction of the support column 11a to be changed by loosening the fastening portion 73.

[0079] As shown in Figures 4 to 6, the bracket 70 has a support portion 76, a pair of restricting walls 77, and a pair of pressing portions 78. As shown in Figure 6, the support portion 76 is a projection that protrudes upward from the rear end of the bracket 70 and extends in the X-axis direction. A recess 70a that opens upward is formed between the base portion 71 and the support portion 76 in the Y-axis direction.

[0080] As shown in Figure 4, the upper surface of the support portion 76 is curved in an arc from one side to the other in the Y-axis direction. The support portion 76 supports the first portion 27 of the projection 26 from below via the cushioning member 80. In other words, the extension 24 is hooked onto the support portion 76 from above.

[0081] The support portion 76 faces the restricting portion 25 of the extension portion 24 in the Y-axis direction. More specifically, the support portion 76 supports the front surface of the restricting portion 25 from the front via the cushioning member 80. As shown in Figure 6, the pair of restricting walls 77 extend rearward from the base 71 and face each other in the X-axis direction with the support portion 76 in between. The pair of restricting walls 77 extend to a position behind the support portion 76. Gaps are provided between both ends of the support portion 76 in the X-axis direction and the pair of restricting walls 77.

[0082] The pair of restricting walls 77, together with the base 71 and the support portion 76, form a recess 70a. The second portion 28 of the extension 24, supported by the support portion 76, is located in the recess 70a (see Figure 4).

[0083] As shown in Figure 2, with the extension portion 24 supported by the bracket 70, the pair of restricting walls 77 cover the extension portion 24 from both sides in the X-axis direction. The pair of restricting walls 77 restrict the movement of the extension portion 24 in both sides in the X-axis direction.

[0084] As shown in Figure 6, each regulating wall 77 has a thickened portion 77a extending rearward from the base 71 and a thinned portion 77b extending rearward from the thickened portion 77a. The thickness of the thinned portion 77b in the X-axis direction is thinner than the thickness of the thickened portion 77a in the X-axis direction. The inner surface of the thinned portion 77b in the X-axis direction is located further outward in the X-axis direction than the inner surface of the thickened portion 77a in the X-axis direction. A accommodating space S is formed between the inner surface of the thinned portion 77b and the rear surface of the thickened portion 77a perpendicular to the inner surface of the thinned portion 77b, in which the corner of the first portion 27 of the extension 24 is accommodated.

[0085] The pair of retaining portions 78 each cover the pair of accommodating spaces S formed by the pair of restricting walls 77 from above. Each retaining portion 78 protrudes toward the accommodating space S from the boundary between the upper end of the thick portion 77a and the upper end of the thin portion 77b.

[0086] As shown in Figure 5, the pair of retaining portions 78 press down on both corners of the first portion 27, which is housed in the pair of housing spaces S, from above. The front surface of the corner of the first portion 27 faces the rear surface of the thickened portion 77a in the Y-axis direction.

[0087] As shown in Figure 8(a), the bass drum pad 12 is configured to be separated from the mounting surface FL of the pedal device 17 by the extension portion 24 being supported from below by the support portion 76 and the clamped portion 22 being sandwiched by the clamp 17b.

[0088] (Operation of bass drum pad 12) As shown in Figures 8(a) and 8(b), when the pad body 31 is not being struck, the first shock absorbing part 61 biases the push plate portion 39 of the stopper 37 upward. In other words, when the pad body 31 is not being struck, the part to be struck 30 is biased in the direction opposite to the guide direction. Since the opposing portion 29 faces the push plate portion 39 in the direction opposite to the guide direction, the push plate portion 39 is biased toward the opposing portion 29 by the first shock absorbing part 61. At this time, the cylindrical second shock absorbing part 62 is flattened by being compressed from below by the push plate portion 39. The compressed second shock absorbing part 62 restricts the rotation of the part to be struck 30 in the direction opposite to the guide direction.

[0089] The elastic force of the first shock-absorbing section 61 is set to such an extent that the second shock-absorbing section 62 is compressed by the pressing plate section 39 when the pad body 31 is not struck. The elastic force of the first shock-absorbing section 61 can be adjusted by making its length in the X-axis direction and its thickness different from those of the second shock-absorbing section 62.

[0090] As shown in Figures 9(a) and 9(b), when the beater 17a strikes the pad body 31, the struck portion 30 rotates in the guide direction around the support shaft 51. At this time, the cylindrical first impact absorbing portion 61 is flattened by being compressed from above by the pressing plate portion 39. The second impact absorbing portion 62, which was compressed into a flat shape by the pressing plate portion 39, becomes cylindrical due to its own restoring force. The rotation of the struck portion 30 in the guide direction is restricted by the compressed first impact absorbing portion 61. Therefore, the rotation range of the struck portion 30 around the support shaft 51 is limited by the first impact absorbing portion 61 and the second impact absorbing portion 62.

[0091] As the pad body 31 is struck by the beater 17a, the pressing plate 39 compresses the first shock-absorbing part 61, and then, due to the restoring force of the first shock-absorbing part 61, compresses the second shock-absorbing part 62 from below while returning to the position of the pad body 31 when it is not being struck. Therefore, as the pad body 31 is struck, the struck part 30 rotates on both sides in the rotational direction around the support shaft 51.

[0092] <Operation of this embodiment> When the pad body 31 is struck by the beater 17a, the struck portion 30 moves relative to the support 20 in the direction of the guide mechanism 50. This prevents the struck portion 30 from moving in a direction different from the guide direction when the pad body 31 is struck by the beater 17a. The impact on the struck portion 30 that has moved in the guide direction is absorbed by the cushion member 60 placed between the struck portion 30 and the support 20.

[0093] <Effects of this embodiment> (1) The bass drum pad 12 comprises a support 20, a striking part 30, a guide mechanism 50, and a cushioning member 60. The striking part 30 includes a pad body 31 that is struck by the beater 17a. The striking part 30 is movably supported with respect to the support 20. The guide mechanism 50 guides the striking part 30 to move in the guide direction relative to the support 20 when the pad body 31 is struck. The cushioning member 60 is positioned between the striking part 30 and the support 20. The cushioning member 60 absorbs the impact acting on the striking part 30.

[0094] With the above configuration, the sensation felt by the performer when striking the pad body 31 with the beater 17a tends to be uniform. Therefore, it is possible to suppress any discomfort the performer may experience. Furthermore, the cushion member 60 is positioned between the striking part 30 and the support 20. This suppresses the generation of contact noise between the striking part 30 and the support 20 when the beater 17a strikes the pad body 31. Consequently, the noise level of the bass drum pad 12 during striking can be improved.

[0095] (2) The guide mechanism 50 includes a support shaft 51 that supports the part to be struck 30 so that it can rotate with respect to the support 20 about axis A. The support shaft 51 guides the part to be struck 30 to move in the guide direction, which is one side of the rotation direction about axis A.

[0096] With the above configuration, the guide mechanism 50 can be implemented with a simpler structure compared to a configuration in which the guide mechanism 50 guides the part to be struck 30 in the horizontal direction. (3) The impacted portion 30 includes a pair of arms 36 that extend from the support shaft 51 and to which the pad body 31 is fixed.

[0097] According to the above configuration, the pad body 31 is struck by the oscillating beater 17a, causing the struck part 30 to rotate around the support shaft 51. Here, the striking direction of the beater 17a is the tangential direction during rotation accompanying the oscillating motion of the beater 17a. In order for a performer to get a feeling close to playing a bass drum when playing the bass drum pad 12, it is preferable that the pad body 31 moves in the direction of the beater 17a's strike at the moment it is struck. According to the above configuration, by lengthening the pair of arms 36 extending from the support shaft 51, the radius of rotation of the pad body 31 is increased, so that the range in which the tangential direction of the pad body 31 during rotation generally aligns with the striking direction of the beater 17a can be increased. As a result, the direction of movement of the pad body 31 can be approximated to the striking direction of the beater 17a, so that the performer can get a feeling close to playing a bass drum.

[0098] (4) The pressing plate portion 39 of the stopper 37 is configured to compress the first impact absorbing portion 61 of the cushion member 60 as the impacted portion 30 rotates around axis A. According to the above configuration, when the impacted portion 30 rotates due to the impact of the pad body 31, the pressing plate portion 39 compresses the first impact absorbing portion 61. This suppresses the transmission of vibrations caused by the impact of the pad body 31 to the mounting surface FL of the pedal device 17 via the support 20.

[0099] Furthermore, with the above configuration, even if the striking position of the beater 17a varies, the impact is uniformly converted into the rotational motion of the pair of arms 36, thereby suppressing variations in the contact position between the stopper 37 and the first shock absorbing part 61. Therefore, it is possible to suppress causing discomfort to the performer.

[0100] (5) The pressing plate portion 39 of the stopper 37 is configured to approach the upper surface of the support 20 as the impacted portion 30 rotates about axis A. The first impact absorbing portion 61 is positioned between the stopper 37 and the upper surface of the support 20.

[0101] With the above configuration, when the part to be struck 30 rotates due to the impact of the pad body 31, the stopper 37 compresses the first shock absorbing part 61 from above. This makes it easier for the impact transmitted from the beater 17a to the part to be struck 30 to escape downwards. Therefore, compared to a configuration in which the first shock absorbing part 61 is compressed horizontally when struck by the beater 17a, the bass drum pad 12 is less likely to move horizontally.

[0102] Furthermore, with the above configuration, the stopper 37 approaches the upper surface of the support 20 as the striking portion 30 rotates about the axis A of the support shaft 51. Therefore, compared to a configuration in which, for example, the stopper 37 extends from the arm 36 along the support shaft 51, it is possible to suppress an increase in the size of the bass drum pad 12 in the direction along the support shaft 51, i.e., in the X-axis direction.

[0103] (6) The second shock-absorbing section 62 is positioned between the opposing section 29 and the stopper 37. According to the above configuration, a second shock-absorbing part 62 is positioned between the opposing part 29 located above the stopper 37 and the stopper 37. Therefore, when the arm 36 rotates in the opposite direction to the guide direction due to the restoring force of the compressed first shock-absorbing part 61 acting on the stopper 37, the stopper 37 is pressed against the second shock-absorbing part 62. This positions the part to be struck 30 when the pad body 31 is not being struck. Consequently, it is possible to suppress variations in the performer's feel when the pad body 31 is repeatedly struck by the beater 17a.

[0104] Furthermore, with the above configuration, it is possible to suppress the generation of contact noise between the stopper 37 and the opposing part 29 when the arm 36 rotates in the opposite direction to the guide direction. (7) The cushion member 60 is made of rubber. The first shock-absorbing part 61 is a hollow cylindrical shape with a central axis extending in the horizontal direction.

[0105] The magnitude of the elastic force generated when rubber is compressed depends on the hardness of the rubber. However, if there is variation in the hardness of the rubber, the magnitude of the elastic force generated when the rubber is compressed will also vary.

[0106] In this regard, according to the above configuration, the first shock-absorbing part 61 is made of rubber and is a hollow cylindrical shape. Therefore, in addition to the elastic force generated when the rubber is compressed, the first shock-absorbing part 61 is also provided with an elastic force generated when the rubber deforms to fill the space in the hollow portion. The magnitude of the elastic force generated when the rubber deforms depends on the shape of the rubber. This makes it easier to secure the required elastic force for the first shock-absorbing part 61 even when there is variation in the hardness of the rubber.

[0107] Furthermore, with the above configuration, since the cushion member 60 is made of rubber, the cushion member 60 can be materialized with a simple structure. (8) The bass drum pad 12 is equipped with a vibration sensor 35.

[0108] When the beater 17a strikes the part being struck 30, if it moves not only in the guide direction but also in a direction different from the guide direction, the detection accuracy of the vibration sensor 35 may decrease. In this regard, the above configuration allows the guide mechanism 50 to suppress movement of the part to be struck 30 in a direction different from the guide direction when struck by the beater 17a. Therefore, a decrease in the detection accuracy of the vibration sensor 35 can be suppressed.

[0109] (9) The bass drum pad 12 is configured such that the extended portion 24 is supported from below by the support portion 76 and the clamped portion 22 is held in place by the clamp 17b, so as to be separated from the mounting surface FL of the pedal device 17.

[0110] According to the above configuration, the extension portion 24 is supported by the support portion 76 of the bracket 70 attached to the support column 11a of the stand 11, and the clamped portion 22 is held in place by the clamp 17b, thereby separating the bass drum pad 12 from the mounting surface FL. This suppresses the transmission of vibrations from the pad body 31 during impact to the mounting surface FL, making it less likely for the performer to feel vibrations. Therefore, it is possible to suppress causing discomfort to the performer.

[0111] Furthermore, because the bass drum pad 12 is separated from the mounting surface FL, contact noise between the bass drum pad 12 and the mounting surface FL when the beater 17a strikes the pad body 31 can be suppressed. Therefore, the quietness of the bass drum pad 12 when it is struck can be improved.

[0112] (10) The extension portion 24 has a restricting portion 25 and a protruding portion 26. The restricting portion 25 faces the bracket 70 on the opposite side from the support column 11a and restricts the movement of the support 20 toward the support column 11a. The support portion 76 supports the protruding portion 26 that protrudes from the restricting portion 25 toward the bracket 70 from below.

[0113] When playing the bass drum pad 12, if the relative position of the bass drum pad 12 and other pads on the electronic drum set 10 changes, the player may find it difficult to play the bass drum pad 12.

[0114] In this regard, according to the above configuration, when the protruding portion 26 is supported by the support portion 76, the restricting portion 25 faces the bracket 70 from the opposite side of the support column 11a. Therefore, the impact of the pad body 31 striking the bass drum pad 12 prevents it from moving closer to the support column 11a. This suppresses changes in the relative position of the bass drum pad 12 and other pads. In addition, it eliminates the need to provide a separate structure for fixing the bass drum pad 12 to the mounting surface FL.

[0115] (11) The bracket 70 has a pressing portion 78 that presses the extension portion 24 from above. When the pad body 31 is struck hard, the stopper 37, which compresses the first shock-absorbing section 61, may rotate vigorously in the opposite direction to the guide direction due to the reaction force during compression. At this time, the impact caused by the stopper 37 compressing the second shock-absorbing section 62 from below causes the bass drum pad 12 to try to float upward.

[0116] In this regard, with the above configuration, since the extension portion 24 is pressed down from above by the pressing portion 78, it is possible to suppress the extension portion 24 from lifting up from the bracket 70 due to the impact when the pad body 31 is struck. Therefore, it is possible to suppress changes in the relative position between the bass drum pad 12 and the stand 11.

[0117] (12) A cushioning member 80 is attached to the portion of the extension 24 that contacts the bracket 70. With the above configuration, it is possible to suppress the generation of contact noise between the extension portion 24 and the bracket 70 when the pad body 31 is struck.

[0118] (13) The bracket 70 is configured to allow the mounting position of the support column 11a to be changed along its length. According to the above configuration, the height position of the bass drum pad 12 from the mounting surface FL can be changed by changing the mounting position of the bracket 70 in the longitudinal direction of the support column 11a. As a result, even if the height position of the pedal device 17 changes due to the placement of the vibration-damping member 90 between the pedal device 17 and the mounting surface FL, as shown in Figure 10, the clamped portion 22 can still be held by the clamp 17b of the pedal device 17. Furthermore, even if multiple types of pedal devices with different clamp height positions are used, the clamped portion 22 can still be held by the clamp of the pedal device. Therefore, the versatility of the bass drum pad 12 can be increased.

[0119] <Example of changes> This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0120] The bracket 70 does not necessarily have to be configured to allow the mounting position of the support column 11a to be changed in the longitudinal direction. The bracket 70 may be attached to the support column 11a by engaging with it, so as not to move relative to the support column 11a at a predetermined position.

[0121] The extension portion 24 does not necessarily need to have a buffer member 80 attached to it. The bracket 70 may also have a single pressing portion 78 that presses the protruding portion 26 from above. In this case, it is preferable that the pressing portion 78 presses the central part of the protruding portion 26 in the X-axis direction from above.

[0122] The bracket 70 does not necessarily have to have a pair of retaining portions 78. The extension portion 24 does not necessarily have a restricting portion 25. In this case, the support 20 may have a projection 26 that protrudes forward from the front end of the base portion 21.

[0123] The bass drum pad 12 does not necessarily have to be equipped with a bracket 70. In this case, the bass drum pad 12 does not necessarily have to be connected to the support column 11a. In addition, the support body 20 does not necessarily have to have a clamped portion 22. In this case, the bass drum pad 12 may be installed on the mounting surface FL. Even in this case, effects similar to those described above (1) to (8) can be achieved.

[0124] The bass drum pad 12 may be a practice bass drum pad that does not have a vibration sensor 35. The first shock-absorbing section 61 may be made of an elastic material other than rubber. This modification can also be applied to the second shock-absorbing section 62 in the same manner.

[0125] The shape of the first shock-absorbing section 61 can be changed to various shapes, such as a solid cylindrical shape. This modification example can also be applied to the second shock-absorbing section 62 in the same manner. The bass drum pad 12 does not necessarily have a second shock absorbing section 62. Even in this case, the pressing plate section 39 is pressed against the opposing section 29 by the biasing force of the first shock absorbing section 61. This positions the impacted section 30 when the pad body 31 is not being struck.

[0126] The bass drum pad 12 does not necessarily have to include the second shock absorbing section 62 and the opposing section 29. The stopper 37 may extend from the arm 36 in the X-axis direction. In this case, it is preferable that the support 20 is shaped to support the cushion member 60 so that the cushion member 60 is positioned in front of the stopper 37.

[0127] The impacted portion 30 does not necessarily have a stopper 37. In this case, for example, as shown in Figure 11, the impacted portion 130 may have a tension coil spring 100 that biases the impacted portion 130 in the opposite direction to the guide direction. In this modified example, the impacted portion 130 has a support body 120 having a support wall 123 that extends to a position behind the arm 36 in the Y-axis direction. The tension coil spring 100 connects the arm 36 and the rear end of the support wall 123. In this modified example, the tension coil spring 100 is stretched as the impacted portion 130 rotates in the guide direction. This absorbs the impact acting on the impacted portion 130.

[0128] The support shaft 51 may be positioned above the pad body 31. In this case, for example, the arm 36 extends downward from the support shaft 51. Also, when the pad body 31 is struck, the stopper 37 compresses the cushion member 60 from below.

[0129] The bass drum pad 12 does not necessarily have an arm 36 and a support shaft 51. In this case, for example, as shown in Figure 12, the pad body 231 may be connected to the support body 220 via a shaft 200 extending in the Y-axis direction. In this modified example, the shaft 200 is inserted into a through hole 231b of a mounting portion 231a that protrudes outward from the pad body 231. The front end of the shaft 200 is fixed to a receiving portion 221 provided on the support body 220. The rear end of the shaft 200 is provided with an enlarged portion 200a that is larger than the portion of the shaft 200 that is inserted into the through hole 231b. The receiving portion 221 is located in front of the mounting portion 231a. A cylindrical cushion member 260 into which the shaft 200 is inserted is positioned between the mounting portion 231a and the receiving portion 221. The mounting portion 231a is biased toward the enlarged portion 200a by the cushion member 260. The cushion member 260 is made of, for example, rubber. The shaft 200 allows the pad body 231 to slide along the axial direction of the shaft 200, while restricting the movement of the pad body 231 in directions other than the axial direction of the shaft 200. Therefore, the shaft 200 guides the pad body 231 to move forward when it strikes. As the pad body 231 moves forward while sliding with the shaft 200, the cushion member 260 is compressed by the mounting portion 231a. The pad body 231 that has moved forward is moved backward by the restoring force of the cushion member 260 and pressed against the enlarged portion 200a. This suppresses vibration of the pad body 231 after impact. The shaft 200 is an example of a "guide mechanism". The cushion member 260 is an example of an "impact absorption portion". The enlarged portion 200a is an example of an "opposing portion". In this configuration, the pad body 231 is biased toward the enlarged portion 200a by the cushion member 260. Therefore, when the pad body 231 is struck, it moves in the guide direction, and then, due to the biasing force of the cushion member 260, it moves in the opposite direction to the guide direction and is pressed towards the enlarged portion 200a. This positions the pad body 231 when it is not being struck.Therefore, variations in the player's feel when repeatedly striking the pad body 231 with the beater 17a can be suppressed. In Figure 12, one end of the pad body 231 in the X-axis direction is shown, but in this modified example, the above structure is provided at multiple locations on the outer circumference of the pad body 231. The cushion member 260 may be positioned away from the shaft 200, between the mounting portion 231a and the receiving portion 221. In this case, the cushion member 260 may be a solid cylindrical shape.

[0130] The bass drum pad 12 does not necessarily have to include a guide mechanism 50 and a cushioning member 60. In this case, it is preferable that the striking part 30 is immovably supported with respect to the support 20. Even with this configuration, the bass drum pad 12 can achieve effects similar to those described in (9) to (13) above, as long as it includes the striking part 30 and the bracket 70.
