Description

Technical Field

[0001] This invention relates to bass drum pads. Background Technology

[0002] Japanese Patent Application Publication No. 2019-128372 discloses an electronic bass drum that is played using a striking mechanism, which includes a mallet that swings when operated by the player's foot. The electronic bass drum has a drumhead and a support for the drumhead, and the drumhead has a striking surface.

[0003] Multiple mounting portions extending outwards are provided on the outer periphery of the drumhead. A drumhead connector, consisting of bolts extending in a direction orthogonal to the striking surface of the drumhead, passes through each mounting portion. The drumhead connector is screwed into a lug located opposite the mounting portion of the drumhead. A cylindrical damping member is mounted on a portion of the multiple drumhead connectors, positioned between the mounting portion and the lug, and the drumhead connector is inserted into the damping member.

[0004] The support frame has a plate-shaped main body that stands vertically and extends along the striking surface of the drumhead. The main body has a through hole through which the drumhead connector passes, and a vibration damping component is fitted into the through hole. The diameter of the through hole is larger than the diameter of the drumhead connector and approximately the same as the diameter of the vibration damping component.

[0005] The drumhead is elastically supported on the bracket by fitting the damping member into the through hole. Therefore, when the drumhead is struck with a hammer, the damping member is compressed in the axial direction by moving the drumhead forward relative to the bracket in the direction of the hammer's strike. This absorbs the impact acting on the drumhead when it is struck.

[0006] The diameter of the through hole in the main body of the support is larger than the diameter of the drumhead connector, and approximately the same as the diameter of the damping member. Furthermore, the damping member is positioned between the outer circumferential surface of the drumhead connector and the inner circumferential surface of the through hole. Therefore, the drumhead connector can move within the through hole while compressing the damping member. As a result, when the drumhead is struck, it may move not only along the axial direction of the damping member but also in a direction different from that axial direction. For example, if the hammer strikes off-center from the center of the drumhead's striking surface, or if two separate points on the striking surface are struck using a double pedal, the damping member is compressed while the drumhead is tilted, and thus the drumhead may vibrate. In particular, the vibration becomes more pronounced when the drumhead is struck rapidly with the hammer. In this case, it may create a sense of disharmony for the performer. Summary of the Invention

[0007] One aspect of the present invention provides a bass drum pad configured to be played using a pedal device having a hammer that oscillates upon being pressed by a player. The bass drum pad includes: a support body; a striking portion comprising a pad body struck by the hammer and movably supported on the support body; a guiding mechanism that, upon striking the pad body, guides the striking portion to move relative to the support body in a guiding direction; and an impact-absorbing portion disposed between the striking portion and the support body to absorb impacts acting on the striking portion.

[0008] Another aspect of the present invention provides a bass drum pad configured to be played using a pedal device having a mallet that oscillates upon being pressed by a player. The bass drum pad includes: a support body; a striking portion comprising a pad body struck by the mallet and supported on the support body; and a bracket configured to be mounted on a support for supporting a percussion instrument different from the bass drum pad. The support body has an extension extending toward the bracket and a clamping portion clamped from above and below by a clamping member of the pedal device. The bracket has a support portion supporting the extension from below. The bass drum pad is configured such that it is supported from below by the support portion via the extension and the clamping portion is clamped by the clamping member, thereby moving away from the mounting surface of the pedal device.

[0010] The following is for reference Figures 1-10 An embodiment of embodying the bass drum pad as a bass drum pad constituting an electronic drum kit will be described. like Figure 1 As shown, the electronic drum kit 10 includes a stand 11, a bass drum pad 12, a snare drum pad 13, a floor tom drum 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 reference). Figure 8 Part (a)). Each pad is supported on the bracket 11. The bass drum pad 12 is an example of an "electronic bass drum pad".

[0011] The electronic drum kit 10 includes a sound source device 16, which emits sound based on the output signals of vibration sensors disposed on each pad. The sound source device 16 is mounted on a bracket 11. The sound source device 16 is connected to the vibration sensors of each pad via cables (not shown).

[0012] The pads other than the bass drum pad 12 are played by the performer striking them with drumsticks (not shown). The bass drum pad 12 is played via a pedal device 17, which has a hammer 17a that swings when the performer presses it. In the hi-hat pad 15a, the timbre changes when struck depending on whether the performer presses the hi-hat pedal 18.

[0013] (Structure of bass drum pad 12) like Figure 2 As shown, the bass drum pad 12 includes a support body 20, a striking portion 30, a guiding mechanism 50, a damping member 60, and a bracket 70. The striking portion 30 includes a pad body 31 that is struck by a hammer 17a. The striking portion 30 is movably, and more specifically rotatably, supported on the support body 20. When the pad body 31 is struck, the guiding mechanism 50 guides the striking portion 30, causing it to move relative to the support body 20 in a guiding direction. The damping member 60 is disposed between the striking portion 30 and the support body 20 and absorbs the impact acting on the striking portion 30. The bracket 70 connects the support body 20 and the support column 11a of the bracket 11. Figure 1 As shown, the support 11a supports the first tom pad 14b and the second tom pad 14c, which are percussion instruments different from the bass drum pad 12.

[0014] In the following description, the directions extending along the X, Y, and Z axes shown in some of the accompanying 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 are opposite each other. The Z-axis direction is the vertical direction. Furthermore, with the bass drum pad 12 as a reference, the direction away from the pedal device 17 in the Y-axis direction will be described as the front, and the direction closer to the pedal device 17 in the Y-axis direction will be described as the rear.

[0015] (Structure of support body 20) like Figure 3 As shown, the support body 20 has a base portion 21, a pair of support walls 23 and an extension portion 24.

[0016] The base portion 21 is a flat plate with its thickness along the Z-axis. The base portion 21 has a rectangular through hole 21a extending through the base portion 21 along the Z-axis and a pair of first slits 21b spaced apart from each other in the X-axis direction. Each first slit 21b extends forward from the leading edge of the through hole 21a.

[0017] A clamping part 22 is provided at the rear end of the base part 21, and the clamping part 22 is clamped by the clamping member 17b of the pedal device 17 (see reference). Figure 8 Part (a) is clamped in from above and below. In the clamped part 22, a rib 22a is provided protruding upward to reinforce the rear end of the base part 21.

[0018] A pair of support walls 23 protrude upward from both ends of the base portion 21 in the X-axis direction and are opposite to each other in the X-axis direction. Each support wall 23 extends along the Y-axis direction. like Figure 2 and Figure 4 As shown, the extension 24 extends from the front end of the base portion 21 toward the bracket 70.

[0019] The extension 24 has a limiting portion 25 and a protrusion 26. The limiting portion 25 protrudes upward in the Z-axis direction from the front end of the base portion 21. The protrusion 26 protrudes toward the bracket 70 in the Y-axis direction from the upper end of the limiting portion 25. The protrusion 26 is supported from below by the bracket 70.

[0020] The limiting part 25 is positioned opposite the bracket 70 to the support column 11a on the opposite side of the bracket 70 in the Y-axis direction, i.e., at the rear, and restricts the support body 20 from moving in a direction closer to the support column 11a.

[0021] like Figure 4As shown, the protrusion 26 has a first portion 27 and a second portion 28. The first portion 27 extends forward from the upper end of the limiting portion 25. The second portion 28 extends obliquely relative to the first portion 27, such that it is positioned lower and further forward from the front end of the first portion 27. Figure 3 As shown, the width of Part 2, 28, in the X-axis direction is smaller than the width of Part 1, 27, in the X-axis direction.

[0022] The base portion 21 has a counter portion 29 located above the stop 37 and opposite the stop 37 (described later). The counter portion 29 is formed by cutting a portion of the limiting portion 25 in the Y-axis direction toward the side opposite to the protrusion 26, i.e., rearward. The counter portion 29 extends parallel to the limiting portion 25 and the base portion 21. The counter portion 29 has a second slit 29a extending forward from the rear end edge of the counter portion 29. Viewed in the Z-axis direction, the second slit 29a is located between a pair of first slits 21b.

[0023] like Figure 4 and Figure 5 As shown, 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 limiting portion 25, and also covers the upper and lower surfaces of the first portion 27.

[0024] like Figure 3 As shown, the buffer member 80 has an insertion hole 80a, into which the protrusion 26 is inserted. The buffer member 80 is mounted to the extension 24 by folding it in a manner that covers the limiting part 25 and the first part 27 with the protrusion 26 inserted into the insertion hole 80a.

[0025] (Structure of the struck part 30) The struck part 30 has a pad body 31, a pair of arms 36 and a stop 37.

[0026] The pad body 31 includes an elastomer 32 and a housing 33 for housing the elastomer 32. The elastomer 32 has a striking surface 32a that is struck by the performer. The elastomer 32 is disc-shaped. The elastomer 32 may include, for example, a sponge and a mesh member disposed on the surface of the sponge. The housing 33 has an opening that exposes the striking surface 32a. A mounting portion 34 is provided on the bottom wall of the housing 33, and a pair of arms 36 are fixed to the mounting portion 34 (see reference). Figure 8 Part (a)). The struck part 30 is supported on the support body 20 in a posture in which the struck surface 32a is approximately orthogonal to the Y-axis direction.

[0027] A pair of arms 36 are fixed to the mounting portion 34 and a 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 a pair of arms 36 are secured to the mounting portion 34 by two bolts 40 arranged along the length of the arms 36 and passing through the pair of arms 36 and the mounting portion 34, and two nuts 41 mounted on the two bolts 40. Each bolt 40 passes through the pair of arms 36 and is inserted into a pair of cylindrical collars 42 inserted into the mounting portion 34. That is, the pair of collars 42 are located between each bolt 40 and the pair of arms 36.

[0028] Bolt 40 is made of metal. Collar 42 is made of resin. Collar 42 serves to prevent contact noise between bolt 40 and arm 36.

[0029] The lower ends of a pair of arms 36 are rotatably supported on a pair of support walls 23 via a support shaft 51 described later. The pair of arms 36 extend in a direction intersecting the support shaft 51, or more specifically, in a direction orthogonal to the support shaft 51.

[0030] A stop 37 extends from a pair of arms 36 and rotates together with the pair of arms 36. The stop 37 has a pair of fixing portions 38 and a pressure plate portion 39. The pair of fixing portions 38 are respectively fixed to the pair of arms 36 by a plurality of screws 43. The pair of fixing portions 38 extend forward from the pair of arms 36. The pressure plate portion 39 connects the front ends of the pair of fixing portions 38 to each other. The pressure plate portion 39 is a flat plate with its thickness along the Z-axis. The pressure plate portion 39 faces the upper surface of the base portion 21. A mounting hole 39a extending through the pressure plate portion 39 along the Z-axis is provided at the front end of the pressure plate portion 39.

[0031] The pressure plate portion 39 is configured to rotate around the support shaft 51 via the struck portion 30, thereby approaching and separating from the upper surface of a base portion 21. like Figure 8 As shown in part (a), the impacted part 30 is equipped with a vibration sensor 35 that detects the vibration of the pad body 31. The vibration sensor 35 is disposed inside the housing 33 between the bottom wall of the housing 33 and the elastic body 32. More specifically, the vibration sensor 35 detects the vibration of the elastic body 32 when it is impacted, and outputs a signal corresponding to the magnitude of the vibration to the sound source device 16.

[0032] (Structure of the guiding mechanism 50) like Figure 3 As shown, the guide mechanism 50 includes a support shaft 51, which supports the striking part 30 so that it can rotate relative to the support body 20 about an axis A extending in the X-axis direction. The support shaft 51 is a bolt that supports the lower ends of a pair of arms 36 so that they can rotate relative to the support body 20.

[0033] The support shaft 51 allows the struck part 30 to move to both sides of the circumferential direction centered on axis A, while restricting the struck part 30 from moving in directions different from the two sides of the circumferential direction. Therefore, the support shaft 51 guides the struck part 30 to move in the direction of rotation centered on axis A, i.e., the guide direction. In this embodiment, the guide direction is the front side of the direction of rotation of the struck part 30 struck by the hammer 17a.

[0034] The guide mechanism 50 includes a pair of collars 52 and nuts 53. Each collar 52 passes through the arm 36 and the support wall 23. Additionally, each collar 52 passes through a washer 54 disposed between the arm 36 and the support wall 23. A 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 mounted at the top end of the support shaft 51.

[0035] When the struck part 30 rotates about the axis A of the support shaft 51, a pair of arms 36 slide relative to a pair of collars 52. Therefore, when the struck part 30 rotates, the support shaft 51 does not rotate.

[0036] The support shaft 51 is made of metal. Each collar 52 and each washer 54 is made of resin. Each collar 52 functions to prevent contact noise between the support shaft 51 and the arm 36. Each washer 54 functions to prevent contact noise between the arm 36 and the support wall 23.

[0037] (Structure of vibration damping component 60) The vibration damping member 60 has a first impact absorbing part 61, a second impact absorbing part 62, a connecting part 63, a pair of first support protrusions 64 and a second support protrusion 65. The first impact absorbing part 61, the second impact absorbing part 62, the connecting part 63, the pair of first support protrusions 64 and the second support protrusion 65 are integrally formed of rubber.

[0038] The first impact-absorbing part 61 is a hollow cylindrical shape with a central axis A1 extending along the X-axis direction. The central axis A1 of the first impact-absorbing part 61 is parallel to the axis A of the support shaft 51. The first impact-absorbing part 61 is disposed between the lower surface of the stop member 37 and the upper surface of the base part 21.

[0039] The second impact-absorbing part 62 is a hollow cylinder with a central axis A2 extending along the X-axis. The central axis A2 of the second impact-absorbing part 62 is parallel to the central axis A1 of the first impact-absorbing part 61. The second impact-absorbing part 62 is disposed between the upper surface of the stop member 37 and the lower surface of the opposing part 29. The length of the second impact-absorbing part 62 in the X-axis direction is shorter than the length of the first impact-absorbing part 61 in the X-axis direction. The wall thickness of the second impact-absorbing part 62 is less than the wall thickness of the first impact-absorbing part 61.

[0040] The connecting portion 63 connects the upper part of the first impact-absorbing portion 61 and the lower part of the second impact-absorbing portion 62. The connecting portion 63 is located at the center of the first impact-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 impact-absorbing portion 62 in the X-axis direction. The connecting portion 63 is disposed inside the mounting hole 39a of the pressure plate portion 39. The connecting portion 63 is disposed inside the mounting hole 39a by inserting the second impact-absorbing portion 62 into the mounting hole 39a while compressing it. As a result, the vibration damping member 60 is mounted on the stop member 37.

[0041] A pair of first support protrusions 64 protrude downwards from the lower part of the first impact-absorbing part 61 in the X-axis direction at intervals. The pair of first support protrusions 64 are respectively engaged with a pair of first slits 21b. Thus, the first impact-absorbing part 61 is supported on the base part 21.

[0042] The second support protrusion 65 protrudes upward from the upper part of the second impact-absorbing part 62. The second support protrusion 65 is engaged with the second slit 29a. Thus, the second impact-absorbing part 62 is supported by the opposing part 29.

[0043] (Structure of bracket 70) like Figure 6 and Figure 7 As shown, the bracket 70 has a base 71, a pair of clamping portions 72, and a fastening portion 73. The pair of clamping portions 72 extend forward from the base 71 and clamp the support column 11a. The fastening portion 73 fastens the pair of clamping portions 72.

[0044] like Figure 7 As shown, a pair of clamping portions 72 are formed with circular retaining holes 72a for retaining the support column 11a and slits 72b connected to the retaining holes 72a. The slits 72b extend throughout the entire Z-axis direction of the bracket 70.

[0045] The fastening part 73 includes a bolt 74 that passes through a pair of clamping parts 72 along the X-axis and a nut 75 embedded in one of the pair of clamping parts 72. The fastening part 73 changes the fastening amount of the support 11a in the pair of clamping parts 72 by changing the amount of screwing of the bolt 74 relative to the nut 75.

[0046] The bracket 70 is configured to be mounted to the support column 11a by fastening a pair of clamping parts 72 using fastening parts 73. Furthermore, the bracket 70 is configured to change its mounting position along the length of the support column 11a by loosening the fastening parts 73.

[0047] like Figures 4-6 As shown, the bracket 70 has a support portion 76, a pair of limiting walls 77, and a pair of pressing portions 78. like Figure 6As shown, the support portion 76 is a protrusion that extends upward from the rear end of the bracket 70 and extends along 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.

[0048] like Figure 4 As shown, the upper surface of the support portion 76 is curved in an arc shape from one side to the other in the Y-axis direction. The support portion 76 supports the first portion 27 of the protrusion 26 from below via the buffer member 80. In other words, the extension 24 is hooked onto the support portion 76 from above.

[0049] The support portion 76 is opposite the limiting portion 25 of the extension portion 24 in the Y-axis direction. More specifically, the support portion 76 supports the front surface of the limiting portion 25 from the front via the buffer member 80. like Figure 6 As shown, a pair of limiting walls 77 extend rearward from the base 71 and are positioned opposite each other across the support portion 76 in the X-axis direction. The pair of limiting walls 77 extend to a position further rearward than the support portion 76. Gaps are provided between the two ends of the support portion 76 in the X-axis direction and the pair of limiting walls 77, respectively.

[0050] A pair of limiting 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 on the support portion 76 is located in the recess 70a (see reference). Figure 4 ).

[0051] like Figure 2 As shown, with the extension 24 supported by the bracket 70, a pair of limiting walls 77 cover the extension 24 from both sides in the X-axis direction. The pair of limiting walls 77 restrict the extension 24 from moving to both sides in the X-axis direction.

[0052] like Figure 6 As shown, each limiting wall 77 has a thick-walled portion 77a extending rearward from the base 71 and a thin-walled portion 77b extending rearward from the thick-walled portion 77a. The thickness of the thin-walled portion 77b in the X-axis direction is thinner than the thickness of the thick-walled portion 77a in the X-axis direction. The inner surface of the thin-walled portion 77b in the X-axis direction is located on the outer side in the X-axis direction than the inner surface of the thick-walled portion 77a in the X-axis direction. A receiving space S is formed between the inner surface of the thin-walled portion 77b and the rear surface of the thick-walled portion 77a, which is orthogonal to the inner surface of the thin-walled portion 77b, and the corner of the first portion 27 of the extension 24 is received in the receiving space S.

[0053] A pair of pressing parts 78 cover a pair of storage spaces S formed by a pair of limiting walls 77 from above. Each pressing part 78 extends toward the storage space S from the boundary portion of the upper end of the thick-walled part 77a and the upper end of the thin-walled part 77b.

[0054] like Figure 5As shown, a pair of pressing parts 78 are pressed down from above and stored in the two corners of the first part 27 of a pair of storage spaces S. The front surface of the corner of the first part 27 is opposite to the rear surface of the thick-walled part 77a in the Y-axis direction.

[0055] like Figure 8 As shown in part (a), the bass drum pad 12 is configured such that it is supported from below by the support portion 76 via the extension portion 24, and is clamped by the clamping member 17b by the clamping portion 22, thereby moving away from the mounting surface FL of the pedal device 17.

[0056] (The action of bass drum pad 12) like Figure 8 As shown in parts (a) and (b), when the pad body 31 is not struck, the pressure plate portion 39 of the stop member 37 is subjected to upward force by the first impact absorbing portion 61. In other words, when the pad body 31 is not struck, the struck portion 30 is subjected to force in the opposite direction to the guiding direction. The opposing portion 29 is opposed to the pressure plate portion 39 in the opposite direction to the guiding direction, so the pressure plate portion 39 is subjected to force towards the opposing portion 29 by the first impact absorbing portion 61. At this time, the cylindrical second impact absorbing portion 62 is compressed from below by the pressure plate portion 39 and becomes flat. The compressed second impact absorbing portion 62 restricts the rotation of the struck portion 30 in the opposite direction to the guiding direction.

[0057] The elastic force of the first impact absorbing part 61 is set to the magnitude of the compression of the second impact absorbing part 62 by the pressure plate part 39 when the pad body 31 is not impacted. The elastic force of the first impact absorbing part 61 can be adjusted by making the length or wall thickness of the first impact absorbing part 61 in the X-axis direction different from that of the second impact absorbing part 62.

[0058] like Figure 9 As shown in parts (a) and (b), when the pad body 31 is struck with the hammer 17a, the struck part 30 rotates in the guiding direction around the support shaft 51. At this time, the cylindrical first impact absorbing part 61 is compressed from above by the pressure plate part 39 and becomes flat. In addition, the second impact absorbing part 62, which is compressed into a flat shape by the pressure plate part 39, becomes cylindrical by its own restoring force. The compressed first impact absorbing part 61 restricts the rotation of the struck part 30 in the guiding direction. In summary, the first impact absorbing part 61 and the second impact absorbing part 62 limit the rotation range of the struck part 30 around the support shaft 51.

[0059] As the hammer 17a strikes the pad body 31, the pressure plate 39 of the first impact-absorbing part 61 is compressed. Through the restoring force of the first impact-absorbing part 61, the second impact-absorbing part 62 is compressed from below, and the pad body 31 returns to its non-impacted position. Therefore, with the impact on the pad body 31, the struck part 30 rotates to both sides of the rotation direction around the support shaft 51.

[0060] <The function of this implementation method> When the pad body 31 is struck by the hammer 17a, the struck portion 30 moves relative to the support body 20 in the guiding direction of the guide mechanism 50. Therefore, when the pad body 31 is struck by the hammer 17a, movement of the struck portion 30 in a direction different from the guiding direction can be suppressed. Furthermore, the impact of the struck portion 30 moving in the guiding direction is absorbed by the vibration damping member 60 disposed between the struck portion 30 and the support body 20.

[0061] <Effects of this implementation method> (1) The bass drum pad 12 includes a support body 20, a striking portion 30, a guiding mechanism 50, and a damping member 60. The striking portion 30 includes a pad body 31 that is struck by the hammer 17a. The striking portion 30 is movably supported on the support body 20. The guiding mechanism 50 guides the striking portion 30 to move relative to the support body 20 in a guiding direction when the pad body 31 is struck. The damping member 60 is disposed between the striking portion 30 and the support body 20. The damping member 60 absorbs the impact acting on the striking portion 30.

[0062] Based on the above structure, the performer's sensation when striking the pad body 31 with the mallet 17a is easily made the same. Therefore, it can suppress any sense of disharmony that may be caused to the performer. Furthermore, the vibration damping member 60 is disposed between the struck portion 30 and the support body 20. Therefore, when the pad body 31 is struck with the hammer 17a, contact noise generated between the struck portion 30 and the support body 20 can be suppressed. Thus, the quietness between the struck portion 30 and the support body 20 when the bass drum pad 12 is struck can be improved.

[0063] (2) The guide mechanism 50 has a support shaft 51, which supports the part to be struck 30 so that it can rotate about axis A relative to the support body 20. The support shaft 51 guides the part to be struck 30 to move in the direction of rotation about axis A, i.e., the guide direction.

[0064] Based on the above structure, compared with the case where the guide mechanism 50 is a structure that guides the struck part 30 in a horizontal direction, the guide mechanism 50 can be implemented with a simple structure. (3) The striking part 30 has a pair of arms 36, which extend from the support shaft 51, and the pad body 31 is fixed to the pair of arms 36.

[0065] According to the above structure, by striking the pad body 31 with the swinging hammer 17a, the struck part 30 rotates around the support shaft 51. Here, the striking direction of the hammer 17a is the tangential direction accompanying the rotation of the hammer 17a. Preferably, the pad body 31 moves in the striking direction of the hammer 17a at the moment of striking the pad body 31, based on the player obtaining a feeling close to playing a bass drum when playing the bass drum pad 12. According to the above structure, by lengthening the pair of arms 36 extending from the support shaft 51, the rotation radius of the pad body 31 is increased, thus increasing the range in which the tangential direction of the pad body 31 during rotation is approximately along the striking direction of the hammer 17a. As a result, the movement direction of the pad body 31 can be made approximately the striking direction of the hammer 17a, thus allowing the player to obtain a feeling close to playing a bass drum.

[0066] (4) The pressure plate portion 39 of the stop member 37 is configured to compress the first impact absorption portion 61 of the vibration damping member 60 by rotating the impacted portion 30 around the axis A. According to the above structure, when the struck part 30 rotates along with the striking pad body 31, the pressure plate part 39 compresses the first impact absorption part 61. As a result, the vibration of the striking pad body 31 that is transmitted to the mounting surface FL of the pedal device 17 via the support body 20 can be suppressed.

[0067] Furthermore, according to the above structure, even if the striking position of the hammer 17a is deviated, since the striking is also transformed into the rotational motion of a pair of arms 36, the deviation in the contact position between the stop 37 and the first impact absorption part 61 can be suppressed. Therefore, it can suppress any sense of disharmony that may be caused to the performer.

[0068] (5) The pressure plate portion 39 of the stop member 37 is configured to approach the upper surface of the support body 20 by rotating the impacted portion 30 around axis A. The first impact absorbing portion 61 is disposed between the stop member 37 and the upper surface of the support body 20.

[0069] According to the above structure, when the struck part 30 rotates along with the striking pad body 31, the stop member 37 compresses the first impact absorption part 61 from above. As a result, the impact transmitted from the hammer 17a to the struck part 30 is easily released downwards. Therefore, compared with the structure in which the first impact absorption part 61 is compressed in the horizontal direction when struck by the hammer 17a, the bass drum pad 12 is less likely to move in the horizontal direction.

[0070] Furthermore, according to the above structure, by rotating the struck part 30 around the axis A of the support shaft 51, the stop 37 approaches the upper surface of the support body 20. Therefore, for example, compared with the structure in which the stop 37 extends from the arm 36 along the support shaft 51, it is possible to suppress the increase in the size of the bass drum pad 12 in the direction along the support shaft 51, that is, in the X-axis direction.

[0071] (6) The second impact absorption part 62 is disposed between the opposing part 29 and the stop member 37. According to the above structure, a second impact-absorbing part 62 is disposed between the opposing part 29 located above the stop 37 and the stop 37. Therefore, when the arm 36 rotates in the opposite direction to the guiding direction due to the restoring force of the compressed first impact-absorbing part 61 acting on the stop 37, the stop 37 presses against the second impact-absorbing part 62. As a result, the struck part 30 is positioned when the pad body 31 is not struck. Therefore, it is possible to suppress any deviation in the player's sensation when repeatedly striking the pad body 31 with the hammer 17a.

[0072] Furthermore, according to the above structure, when the arm 36 rotates in the opposite direction to the guiding direction, the contact noise generated between the stop 37 and the opposing part 29 can be suppressed. (7) The vibration damping 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.

[0073] The magnitude of the elastic force generated by compressing rubber depends on the hardness of the rubber. However, if the hardness of the rubber varies, the magnitude of the elastic force generated by compressing the rubber will also vary.

[0074] In this respect, according to the above structure, the first impact-absorbing part 61 is formed of rubber and is a hollow cylindrical shape. Therefore, in the first impact-absorbing part 61, in addition to the elastic force generated by the compression of the rubber, an elastic force generated by the deformation of the rubber to fill the space of the hollow part is also applied. The magnitude of the elastic force generated by the deformation of the rubber depends on the shape of the rubber. Thus, even if the hardness of the rubber deviates, the required elastic force of the first impact-absorbing part 61 can be easily ensured.

[0075] Furthermore, according to the above structure, the vibration damping member 60 is formed of rubber, thus enabling the vibration damping member 60 to be embodied with a simple structure. (8) The bass drum pad 12 is equipped with a vibration sensor 35.

[0076] When the hammer 17a is used to strike, if the struck part 30 moves not only in the guiding direction but also in a direction different from the guiding direction, the detection accuracy of the vibration sensor 35 may be reduced. In this respect, according to the above structure, the guide mechanism 50 can be used to prevent the struck part 30 from moving in a direction different from the guide direction when struck by the hammer 17a. Therefore, the reduction in the detection accuracy of the vibration sensor 35 can be prevented.

[0077] (9) The bass drum pad 12 is configured such that it is supported from below by the support portion 76 via the extension portion 24, and is clamped by the clamping member 17b by the clamping portion 22, thereby moving away from the mounting surface FL of the pedal device 17.

[0078] According to the above structure, the extension 24 is supported by the support portion 76 of the bracket 70 mounted on the support column 11a of the bracket 11, and the clamped portion 22 is clamped by the clamping member 17b, thereby removing the bass drum pad 12 from the setting surface FL. This suppresses the transmission of vibrations from the pad body 31 during impact to the setting surface FL, making it difficult for the performer to feel the vibrations. Therefore, it suppresses any sense of disharmony that might be felt by the performer.

[0079] Furthermore, since the bass drum pad 12 is positioned away from the mounting surface FL, contact noise generated between the bass drum pad 12 and the mounting surface FL can be suppressed when the pad body 31 is struck with the hammer 17a. Therefore, the quietness of the bass drum pad 12 during impact can be improved.

[0080] (10) The extension 24 has a limiting portion 25 and a protrusion 26. The limiting portion 25 is opposite to the bracket 70 on the side opposite to the support column 11a across the bracket 70, and limits the movement of the support body 20 toward the support column 11a. The support portion 76 supports the protrusion 26 protruding from the limiting portion 25 toward the bracket 70 from below.

[0081] When playing the bass drum pad 12, if the relative position of the bass drum pad 12 and the other pads in the electronic drum kit 10 changes, the player may find it difficult to play the bass drum pad 12.

[0082] In this respect, according to the above structure, with the protrusion 26 supported by the support 76, the limiting part 25 faces the bracket 70 from the side opposite to the support column 11a. Therefore, the movement of the bass drum pad 12 towards the support column 11a due to the impact of the pad body 31 can be limited. As a result, changes in the relative position of the bass drum pad 12 and other pads can be suppressed. Alternatively, a separate structure for fixing the bass drum pad 12 to the mounting surface FL may not be required.

[0083] (11) The bracket 70 has a pressing part 78 that presses down from above the extension 24. When the pad body 31 is struck violently, the stop 37 that compresses the first impact absorption part 61 may rotate violently in the opposite direction to the guiding direction due to the reaction force during compression. At this time, due to the impact of the stop 37 compressing the second impact absorption part 62 from below, the bass drum pad 12 will lift upward.

[0084] In this respect, according to the above structure, since the extension 24 is pressed from above by the pressing part 78, it is possible to prevent the extension 24 from floating off the bracket 70 due to the impact of the pad body 31. Therefore, it is possible to prevent changes in the relative position of the bass drum pad 12 and the bracket 11.

[0085] (12) A buffer member 80 is installed in the part of the extension 24 that contacts the bracket 70. According to the above structure, it is possible to suppress contact noise generated between the extension 24 and the bracket 70 when the pad body 31 is struck.

[0086] (13) The bracket 70 is configured to change the installation position in the length direction of the support column 11a. Based on the above structure, by changing the mounting position of the bracket 70 relative to the support column 11a along its length, the height position of the bass drum pad 12, measured from the mounting surface FL, can be changed. Thus, as... Figure 10 As shown, even when the height position of the pedal device 17 changes due to the placement of the anti-vibration member 90 between the pedal device 17 and the mounting surface FL, the clamping member 17b of the pedal device 17 can still clamp the clamped portion 22. Furthermore, for example, even when using multiple pedal devices with different clamping member height positions, the clamping member of the pedal device can still clamp the clamped portion 22. Therefore, the versatility of the bass drum pad 12 can be improved.

[0087] <Variation Example> This embodiment can be implemented in the following variations. This embodiment and the following variations can be combined and implemented with each other within the scope of technical non-contradiction.

[0088] The bracket 70 may not be configured to change its installation position along the length of the support column 11a. Alternatively, the bracket 70 may be installed on the support column 11a in a predetermined position without relative movement by engaging with it.

[0089] • It is also possible to omit the installation of the buffer component 80 on the extension 24. The bracket 70 can also press the protrusion 26 from above using a single pressing part 78. In this case, the pressing part 78 preferably presses the central portion of the protrusion 26 from above in the X-axis direction.

[0090] • The bracket 70 may also not have a pair of pressing parts 78. • The extension 24 may also be without the limiting part 25. In this case, the support 20 may also have a protrusion 26 that protrudes forward from the front end of the base 21.

[0091] • The bass drum pad 12 may not have a bracket 70. In this case, the bass drum pad 12 may not be connected to the support column 11a. Furthermore, the support body 20 may not have a clamping part 22. In this case, the bass drum pad 12 may be provided on the mounting surface FL. Even in this case, the effects corresponding to the effects (1) to (8) described above can still be achieved.

[0092] • The bass drum pad 12 can also be a practice bass drum pad without the vibration sensor 35. • The first impact-absorbing part 61 can also be formed of an elastic material different from rubber. This modification also applies to the second impact-absorbing part 62.

[0093] The shape of the first impact-absorbing part 61 can be changed to various shapes, such as a solid cylinder. This modified example can also be applied to the second impact-absorbing part 62. • The bass drum pad 12 may not have the second impact absorption section 62. Even in this case, the pressure plate section 39 is pressed against the opposing section 29 by the force of the first impact absorption section 61. As a result, when the unpadded main body 31 is struck, the struck section 30 is positioned.

[0094] • The bass drum pad 12 may also be without the second shock absorption part 62 and the opposing part 29. The stop 37 may also extend from the arm 36 along the X-axis. In this case, the support 20 is preferably shaped to support the damping member 60 in such a way that the damping member 60 is disposed in front of the stop 37.

[0095] • The struck part 30 may also lack the stop 37. In this case, for example, as Figure 11 As shown, the impacted portion 130 may also include a tension coil spring 100 that applies force to the impacted portion 130 in the opposite direction to the guiding direction. In this modified example, the impacted portion 130 includes a support body 120, which has a support wall 123 extending in the Y-axis direction to a position further rearward than the arm 36. 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 by rotating the impacted portion 130 in the guiding direction. As a result, the impact acting on the impacted portion 130 can be absorbed.

[0096] • The support shaft 51 may also be positioned above the pad body 31. In this case, for example, the arm 36 extends downward from the support shaft 51. Additionally, when the pad body 31 is struck, the stop 37 compresses the damping member 60 from below.

[0097] • The bass drum pad 12 may also be without the arm 36 and support shaft 51. In this case, for example, as Figure 12As shown, the pad body 231 can also be connected to the support body 220 via a shaft 200 extending along the Y-axis. In this modified example, the shaft 200 is inserted into a through hole 231b in a mounting portion 231a protruding outward from the pad body 231. The front end of the shaft 200 is fixed to a bearing portion 221 provided in the support body 220. An enlarged portion 200a is provided at the rear end of the shaft 200, which is larger than the portion of the shaft 200 inserted into the through hole 231b. The bearing portion 221 is located in front of the mounting portion 231a. A cylindrical damping member 260 is disposed between the mounting portion 231a and the bearing portion 221, and the shaft 200 is inserted into the damping member 260. The mounting portion 231a is subjected to force by the damping member 260 toward the enlarged portion 200a. The damping member 260 is, for example, formed of rubber. The shaft 200 allows the pad body 231 to slide along the axial direction of the shaft 200, while restricting the pad body 231 from moving in a direction different from the axial direction of the shaft 200. Therefore, the shaft 200 guides the pad body 231 forward when it is struck. As the pad body 231 slides along the shaft 200 and moves forward, the damping member 260 is compressed by the mounting portion 231a. The forward-moving pad body 231 moves backward by the restoring force of the damping member 260 and presses against the enlarged portion 200a. This suppresses the vibration of the pad body 231 after impact. The shaft 200 is an example of a "guide mechanism." The damping member 260 is an example of an "impact absorption portion." The enlarged portion 200a is an example of an "opposing portion." In this structure, the pad body 231 is subjected to force by the damping member 260 toward the enlarged portion 200a. Therefore, the pad body 231, which moves in the guiding direction as it is struck, is moved in the opposite direction by the force of the damping member 260 and pressed against the enlargement portion 200a. Thus, the pad body 231 is positioned when not struck. Therefore, any deviation in the player's sensation when repeatedly striking the pad body 231 with the hammer 17a can be suppressed. Figure 12 The figure shows one end of the pad body 231 in the X-axis direction, but in this modified example, the above-described structure is provided at multiple locations on the outer periphery of the pad body 231. Furthermore, the damping member 260 may also be positioned between the mounting portion 231a and the bearing portion 221 at a location away from the shaft 200. In this case, the damping member 260 may also be a solid cylinder.

[0098] • The bass drum pad 12 may also be without the guide mechanism 50 and the damping member 60. In this case, it is preferable that the struck part 30 is supported on the support body 20 without being movable. Even with such a structure, if the bass drum pad 12 has the struck part 30 and the bracket 70, it can achieve the effects corresponding to the effects (9) to (13) described above.
