Description

Technical Field

[0001] The present invention relates to a support structure for a cymbal pad.

Background Art

[0002] Patent Document 1 discloses a disk-shaped electronic pad imitating a cymbal. A hitting range assumed to be hit is set in a part on the upper surface of the electronic pad. A sensor for detecting a hit on the electronic pad is arranged only in the hitting range.

[0003] The electronic pad has a mounting hole through which a pole passes. A cylindrical rotation restricting member is fixed to the pole by a fixture. The upper end portion of the rotation restricting member fits into a wedge-shaped recess formed around the mounting hole on the lower surface of the electronic pad. When the rotation restricting member fits into the recess, the rotation of the electronic pad with respect to the pole is restricted, so that the orientation of the electronic pad with respect to the player is determined so that the hitting range is at a predetermined position.

[0004] Further, a screw portion is formed at the upper end portion of the pole protruding from the electronic pad. By attaching a wing nut to the screw portion, the electronic pad is attached to the pole. When adjusting the orientation of the electronic pad with respect to the player, the player first removes the wing nut from the pole and operates the fixture to release the fixing between the pole and the rotation restricting member. Then, with the rotation restricting member fitted into the recess, the player changes the orientation of the electronic pad by rotating the electronic pad together with the rotation restricting member with respect to the pole. Finally, the player operates the fixture to fix the rotation restricting member to the pole and attaches the wing nut to the pole.

Patent Document 1

[0006] In the electronic pad described in Patent Document 1, it is difficult for the performer to see the rotation-stopping member and fasteners from above the electronic pad. Therefore, when adjusting the orientation of the electronic pad, the performer needs to look at the electronic pad from below and operate the fasteners to fix or release the pole and rotation-stopping member.

[0007] Furthermore, to adjust the orientation of the electronic pad, the performer can remove the electronic pad from the pole and then align the recess of the electronic pad with the rotation-stopping member so that the electronic pad is in the desired orientation. Even in this case, the performer still needs to look at the electronic pad from below and operate the fastener.

[0008] For the reasons stated above, adjusting the orientation of the electronic pads relative to the performer is a time-consuming process. [Means for solving the problem]

[0009] This section describes a support structure for cymbal pads that solves the above problems. [Aspect 1] A cymbal pad support structure comprising a support rod, a cymbal pad having an insertion hole into which the support rod is inserted, and a fixing member fixed to a portion of the support rod that protrudes above the cymbal pad, wherein the fixing member is configured to be switchable between a fixed state in which it is attached to the support rod so as not to move relative to it, and an unfixed state in which it is attached so as to be movable relative to the support rod, a locking portion is provided on the upper surface of the cymbal pad, and the fixing member is provided with a locking portion that restricts the rotation of the cymbal pad about the support rod when the locking portion is locked to it, the cymbal pad support structure.

[0010] According to the above configuration, the locking portion of the cymbal pad engages with the locking portion of the fixing member in the fixed state, thereby restricting the rotation of the cymbal pad around the support rod. In the above configuration, when adjusting the orientation of the cymbal pad relative to the performer, the performer first switches the fixing member from a fixed state to an unfixed state. This allows the fixing member to move relative to the support rod. Then, while maintaining the locking and locked parts locked together, the performer rotates the fixing member together with the cymbal pad relative to the support rod, thereby changing the orientation of the cymbal pad to the desired direction. Finally, the performer switches the fixing member back from an unfixed state to a fixed state.

[0011] According to the above configuration, the fixing member is fixed to the portion of the support rod that protrudes above the cymbal pad. Therefore, when adjusting the orientation of the cymbal pad, the performer can switch the fixing member between the fixed and unfixed states while checking from above the cymbal pad. As a result, the performer can operate the fixing member without having to change their posture significantly, such as by peering at the cymbal pad from below. Thus, the process of adjusting the orientation of the cymbal pad relative to the performer can be easily performed.

[0012] [Aspect 2] The cymbal pad support structure according to [Aspect 1], wherein one of the locking portion and the locked portion is a convex portion, and the other of the locking portion and the locked portion is a concave portion that fits into the convex portion.

[0013] According to the above configuration, the protrusion fits into the recess, thereby locking the locking part and the locked part together. This makes it easier for the performer to confirm from above that the protrusion is fitted into the recess.

[0014] [Aspect 3] The cymbal pad support structure according to [Aspect 2], wherein the locking portion is the convex portion and the locked portion is the concave portion. According to the above configuration, for example, if the locking portion is a recess and the locked portion is a convex portion, it is necessary to ensure sufficient thickness in the cymbal pad to form the recess. This may limit the shape of the cymbal pad.

[0015] In this respect, with the above configuration, since the locking portion is a convex portion, the degree of freedom in the shape of the cymbal pad can be increased compared to the case where the locking portion is a concave portion. [Aspect 4] The cymbal pad support structure according to [Aspect 3], wherein the insertion hole penetrates the protrusion, the outer surface of the protrusion includes a restricting surface, and the inner surface of the recess includes a contact surface that extends along the restricting surface and contacts the restricting surface.

[0016] With the above configuration, since the insertion hole penetrates the protrusion, the protrusion and the support rod are located on the same axis. Therefore, when the fixing member is attached to the support rod, the protrusion fits into the recess. As a result, the restricting surface and the contact surface come into contact, restricting the rotation of the cymbal pad. Therefore, the work of attaching the fixing member to the support rod and the work of locking the locking part and the locked part can be performed simultaneously or continuously. Thus, the work of fixing the cymbal pad to the support rod can be performed smoothly.

[0017] [Aspect 5] The cymbal pad support structure according to [Aspect 4], comprising a case body that houses the part to be struck, and a support member formed of an elastic material that constitutes the protrusion and is attached to the case body.

[0018] According to the above configuration, the support member attached to the case body forms a protrusion, and the support rod inserted into the insertion hole of the protrusion passes through the support member. Therefore, a support member made of elastic material is interposed between the case body and the support rod, and between the case body and the fixing member. This makes it possible to suppress the generation of contact noise between the cymbal pad and the support rod, and between the cymbal pad and the fixing member when the cymbal pad is struck.

[0019] [Aspect 6] When the axial direction of the portion of the support rod inserted into the insertion hole is defined as the first direction, the direction perpendicular to the first direction is defined as the second direction, and the direction perpendicular to both the first and second directions is defined as the third direction, the cymbal pad has a striking surface, and at least one portion of the outer surface of the convex portion in the second direction is formed by the planar restricting surface extending in the third direction, and when viewed from the first direction, the striking surface is provided alongside the convex portion in the third direction, and a gap is provided between the outer circumferential surface of the support rod and the inner circumferential surface of the insertion hole to allow the cymbal pad to swing, the cymbal pad support structure according to [Aspect 4] or [Aspect 5].

[0020] According to the above configuration, a gap is provided between the outer surface of the support rod and the inner surface of the insertion hole that allows the cymbal pad to swing. Here, at least one portion of the outer surface of the protrusion in the second direction is formed by a restricting surface. Since the restricting surface is in contact with the contact surface of the fixing member in the second direction, the up-and-down swinging of the end of the cymbal pad in the second direction is restricted. On the other hand, since the restricting surface is planar and extends in the third direction, the sliding of the restricting surface with the contact surface allows the end of the cymbal pad in the third direction to swing up and down. Therefore, the performer can play the cymbal pad while swinging it up and down by striking the striking surface which is aligned with the protrusion in the third direction when viewed from the first direction.

[0021] [Aspect 7] The inner peripheral surface of the insertion hole includes a fulcrum portion that contacts both side portions of the outer peripheral surface of the support rod in the third direction, a first guide portion provided below the fulcrum portion, and a second guide portion provided above the fulcrum portion. The first guide portion has a first gap that allows the cymbal pad to swing between it and the support rod on one side of the support rod in the third direction. The second guide portion has a second gap that allows the cymbal pad to swing between it and the support rod on the other side of the support rod in the third direction. The portion of the first guide portion excluding the portion forming the first gap and the portion of the second guide portion excluding the portion forming the second gap are in contact with the outer peripheral surface of the support rod. The support structure of the cymbal pad according to [Aspect 6].

[0022] According to the above configuration, the first guide portion provided below the fulcrum portion has a first gap between it and the support rod on one side of the support rod in the third direction. The second guide portion provided above the fulcrum portion has a second gap between it and the support rod on the other side of the support rod in the third direction. Therefore, when the player strikes the struck surface of the cymbal pad from above, the cymbal pad rotates about the fulcrum portion as a fulcrum. Along with this rotation, the first guide portion moves from one side to the other side in the third direction to contact the support rod so as to fill the first gap. At the same time, the second guide portion moves from the other side to the one side in the third direction to contact the support rod so as to fill the second gap. Here, in the state before the struck surface is struck, the portion of the first guide portion excluding the portion forming the first gap and the portion of the second guide portion excluding the portion forming the second gap are in contact with the outer peripheral surface of the support rod. Therefore, in addition to the regulating surface and the contact surface, the swinging of the cymbal pad is guided by the first guide portion and the second guide portion so that one end portion of the cymbal pad in the third direction swings up and down. Therefore, the swinging of the cymbal pad is likely to be stabilized.

[0023] [Aspect 8] The support structure of the cymbal pad according to any one of [Aspect 1] to [Aspect 7], comprising an elastic member attached to the support rod and supporting the cymbal pad from below.

[0024] According to the above configuration, the cymbal pad is supported from below by the elastic member, so that the cymbal pad is positioned in the longitudinal direction of the support rod. Further, when the cymbal pad is struck, the elastic member elastically deforms, causing the cymbal pad to swing. Therefore, the player can play while swinging the cymbal pad.

[0025] [Aspect 9] The support structure of the cymbal pad according to [Aspect 8], wherein the fixing member is configured to be able to change the fixing position in the longitudinal direction of the support rod. According to the above configuration, by changing the fixing position of the fixing member in the longitudinal direction of the support rod, the pressing degree of the cymbal pad against the elastic member can be adjusted. Thereby, the swinging condition of the cymbal pad can be adjusted.

[0026] [Aspect 10] The support structure of the cymbal pad according to any one of [Aspect 1] to [Aspect 9], wherein the fixing member has a pair of clamping portions that sandwich the support rod and a tightening portion that tightens the pair of clamping portions.

[0027] For example, in the case of a configuration in which the fixing member is fixed to the support rod by the engagement of a male thread formed on the support rod and a female thread formed on the fixing member, if a force in the circumferential direction of the insertion hole acts on the cymbal pad during the performance of the cymbal pad, the engagement between the male thread and the female thread may be loosened. In this case, the orientation of the cymbal pad with respect to the player may change during the performance of the cymbal pad.

[0028] In this regard, according to the above configuration, by tightening the pair of clamping portions in the state of sandwiching the support rod with the tightening portion, the fixing member is attached to the support rod so as not to be relatively movable. Therefore, even when a force in the circumferential direction of the insertion hole acts on the cymbal pad, the tightening force of the tightening portion is unlikely to decrease. Therefore, the orientation of the cymbal pad with respect to the player is unlikely to change during the performance of the cymbal pad.

[0029] [Aspect 11] A support structure for a cymbal pad according to any one of [Aspect 1] to [Aspect 10], comprising a bracket connecting the support column of a stand installed on the floor surface and the support rod, wherein the support rod has a base portion extending vertically, an offset portion extending from the base portion in a direction different from the longitudinal direction of the base portion, and an insertion portion extending upward from the offset portion and being inserted into the insertion hole, the bracket has a pair of first clamping portions that form a first holding hole for holding the support column and clamp the support column, a first tightening portion that tightens the pair of first clamping portions, a pair of second clamping portions that form a second holding hole for holding the base portion and clamp the base portion, and a second tightening portion that tightens the pair of second clamping portions, wherein the central axis of the first holding hole is along the central axis of the second holding hole.

[0030] According to the above configuration, the central axis of the first holding hole of the first clamping part aligns with the central axis of the second holding hole of the second clamping part. Therefore, the support column and the support rod extending along the support column can be connected by a bracket.

[0031] Furthermore, the position of the bracket relative to the support column can be changed by loosening the tightening of the pair of first clamping parts by the first clamping part and rotating the bracket. In addition, the position of the support rod relative to the bracket can be changed by loosening the tightening of the pair of second clamping parts by the second clamping part and rotating the support rod. Here, since the support rod has an offset part, rotating the support rod relative to the bracket changes the position of the insertion part relative to the support column, that is, the position of the cymbal pad relative to the support column. From the above, by combining the rotation of the bracket relative to the support column and the rotation of the support rod relative to the bracket, the degree of freedom in adjusting the position of the cymbal pad relative to the support column can be increased. Therefore, the distance between the performer and the cymbal pad can be suitably adjusted.

[0032] [Aspect 12] The cymbal pad is an electronic cymbal pad equipped with a vibration sensor for detecting vibrations of the cymbal pad, the cymbal pad support structure according to any one of [Aspect 1] to [Aspect 11].

[0033] According to the above configuration, the support structure for a cymbal pad can be applied as the support structure for an electronic cymbal pad. [Effects of the Invention]

[0034] According to the present invention, the process of adjusting the orientation of the cymbal pad relative to the performer can be easily performed. [Brief explanation of the drawing]

[0036] The following describes one embodiment in which a cymbal pad support structure is applied to the cymbal pads of an electronic drum set, with reference to Figures 1 to 13. 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 floor. Each pad is supported by the stand 11.

[0037] 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).

[0038] 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.

[0039] The hi-hat cymbal pad 15a, the first cymbal pad 15b, and the second cymbal pad 15c have the same configuration. Hereafter, the hi-hat cymbal pad 15a, the first cymbal pad 15b, and the second cymbal pad 15c will be collectively referred to as "cymbal pad 15". Cymbal pad 15 is an example of an "electronic cymbal pad".

[0040] (Support structure of cymbal pad 15) As shown in Figure 2, the support structure for the cymbal pad 15 comprises a support rod 20, a bracket 30, the cymbal pad 15, a fixing member 70, a receiving member 80, and an elastic member 90. The support rod 20 is connected to the support column 11a of the stand 11 via the bracket 30. The cymbal pad 15 is supported by the support rod 20. The fixing member 70, the receiving member 80, and the elastic member 90 are attached to the support rod 20.

[0041] (Configuration of the support rod 20) The support rod 20 has a base portion 21, an offset portion 22, and an insertion portion 23. The base portion 21 extends linearly in the vertical direction. The offset portion 22 extends linearly from the upper end of the base portion 21 in a direction different from the longitudinal direction of the base portion 21. More specifically, the offset portion 22 extends at an inclination with respect to the vertical direction such that it is located higher the further it is from the base portion 21 in the horizontal direction. The insertion portion 23 extends linearly upward from the upper end of the offset portion 22. The insertion portion 23 extends parallel to the base portion 21. The insertion portion 23 is the part of the support rod 20 that is inserted into the second insertion hole 64 of the cymbal pad 15, which will be described later. The insertion portion 23 protrudes above the cymbal pad 15. The support rod 20 has, for example, a circular cross-section.

[0042] 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 Z-axis direction, X-axis direction, and Y-axis direction are examples of the first, second, and third directions, respectively. The Z-axis direction is the vertical direction and coincides with the axial direction of the insertion portion 23.

[0043] (Configuration of bracket 30) As shown in Figure 3, the bracket 30 connects the support column 11a of the stand 11 to the base 21 of the support rod 20. The bracket 30 has a pair of first clamping parts 31 that grip the cylindrical support column 11a and a first fastening part 32 that tightens the pair of first clamping parts 31.

[0044] Each pair of first clamping portions 31 forms a circular first holding hole 31a for holding the support column 11a, and a first slit 31b connected to the first holding hole 31a. The first clamping portion 32 includes a first bolt 33 that passes through a pair of first clamping portions 31 and a first nut 34 embedded in one of the pair of first clamping portions 31. The first clamping portion 32 can change the amount of tightening of the support column 11a in the pair of first clamping portions 31 by changing the amount the first bolt 33 is screwed into the first nut 34.

[0045] The bracket 30 has a pair of second clamping portions 35 that clamp the base portion 21, and a second fastening portion 36 that tightens the pair of second clamping portions 35. The pair of second clamping portions 35 form a circular second holding hole 35a that holds the base portion 21 and a second slit 35b connected to the second holding hole 35a. The central axis L1 of the first holding hole 31a is aligned with the central axis L2 of the second holding hole 35a. More specifically, the central axis L1 of the first holding hole 31a and the central axis L2 of the second holding hole 35a extend parallel to each other.

[0046] The second tightening portion 36 includes a second bolt 37 that passes through a pair of second clamping portions 35 and a second nut 38 embedded in one of the pair of second clamping portions 35. The amount of tightening of the base 21 in the pair of second clamping portions 35 can be changed by changing the amount the second bolt 37 is screwed into the second nut 38.

[0047] (15 cymbal pad configuration) As shown in Figure 4, the cymbal pad 15 comprises a striking surface 40, a case 41, a diaphragm 50, a vibration sensor 51, a first sponge 55, and a second sponge 56.

[0048] The striking portion 40 has a striking surface 40a that is struck by the performer. The striking surface 40a is provided only on a part of the circumferential direction of the cymbal pad 15, centered on the convex portion 63, which will be described later. More specifically, the striking surface 40a is provided alongside the convex portion 63 in the Y-axis direction. The striking surface 40a is not provided alongside the convex portion 63 in the X-axis direction.

[0049] The striking surface 40 is rectangular in shape, elongated in the X-axis direction, when viewed from above. The striking surface 40 includes, for example, a sponge and a mesh member provided on the surface of the sponge. The cymbal pad 15 is positioned so that the striking surface 40 faces the performer in the Y-axis direction.

[0050] In the following explanation, the direction away from the performer in the Y-axis direction will be described as forward, and the direction towards the performer in the Y-axis direction will be described as backward, with the cymbal pad 15 as the reference point. The case 41 comprises a case body 42 that houses the part to be struck 40, and a cover 60 that is detachably attached to the case body 42. The cover 60 is an example of a "support member". The case body 42 is made of, for example, a hard resin material. The cover 60 is made of, for example, an elastic material such as a soft resin material.

[0051] The case body 42 has a housing portion 43 for housing the part to be struck 40 and a case-side flange portion 44 that protrudes forward from the housing portion 43. The housing section 43 is open upward and to the rear. The case-side flange 44 protrudes forward from the opening edge of the housing section 43. The width of the case-side flange 44 in the X-axis direction decreases towards the front. The case-side flange 44 has a first insertion hole 45 into which the insertion section 23 of the support rod 20 is inserted.

[0052] Inside the housing section 43, the impacted part 40, the diaphragm 50, the second sponge 56, the vibration sensor 51, and the first sponge 55 are stacked in order from top to bottom. The diaphragm 50 is disc-shaped. The diaphragm 50 is in contact with the lower surface of the part to be struck 40.

[0053] The vibration sensor 51 detects the vibration of the cymbal pad 15. More specifically, the vibration sensor 51 detects the vibration of the diaphragm 50 when the striking part 40 is struck, and outputs a signal to the sound source device 16 corresponding to the magnitude of the vibration of the diaphragm 50. The vibration sensor 51 has a flat detection unit 52 that detects the vibration of the diaphragm 50, and a cable 53 connected to the detection unit 52. The detection unit 52 is, for example, a disc-shaped piezoelectric element. A jack 54 is provided at the end of the cable 53 to which a plug (not shown) extending from the sound source device 16 is connected.

[0054] The first sponge 55 is disc-shaped. The first sponge 55 presses the detection unit 52 and the diaphragm 50 toward the back surface of the part to be struck 40. The second sponge 56 is disc-shaped. The second sponge 56 is sandwiched between the diaphragm 50 and the vibration sensor 51.

[0055] The cover 60 has a pressing portion 61 that presses down on the part to be struck 40 and a cover-side flange portion 62 that covers the case-side flange portion 44 from above. The clamping portion 61 has a first portion 61a extending in the X-axis direction and a pair of second portions 61b extending rearward from both ends of the first portion 61a. The clamping portion 61 is U-shaped and opens to the rear in a plan view.

[0056] The cover-side flange portion 62 protrudes forward from the first portion 61a. The width of the cover-side flange portion 62 in the X-axis direction decreases as it extends forward. A protrusion 63 is provided on the upper surface of the cymbal pad 15, or more specifically, on the upper surface of the cover-side flange 62. The protrusion 63 is formed integrally with the cover-side flange 62. The cross-sectional shape of the protrusion 63 perpendicular to the X-axis direction is semicircular. The protrusion 63 is an example of a "locking part".

[0057] The outer surface of the protrusion 63 includes a curved surface 63a and a pair of first restricting surfaces 63b. The curved surface 63a is curved in an arc shape so as to be convex upward from one side to the other in the Y-axis direction. The pair of first restricting surfaces 63b are continuous with the curved surface 63a and constitute both sides of the protrusion 63 in the X-axis direction. Each first restricting surface 63b is a plane perpendicular to the X-axis direction. That is, each first restricting surface 63b is planar in shape extending in the Y-axis direction and the Z-axis direction. Each first restricting surface 63b is semicircular when viewed from the X-axis direction. The first restricting surface 63b is an example of a "restricting surface".

[0058] As shown in Figures 5 and 8, the cover-side flange portion 62 has a second insertion hole 64 into which the insertion portion 23 of the support rod 20 is inserted. The second insertion hole 64 penetrates the protrusion 63 and opens onto the curved surface 63a. The second insertion hole 64 is an example of an "insertion hole".

[0059] The cymbal pad 15 is supported by an insertion portion 23 inserted into a second insertion hole 64. The cymbal pad 15 extends cantilevered from the insertion portion 23. The cymbal pad 15 is rotatable about the insertion portion 23 when the insertion portion 23 is inserted into the second insertion hole 64 and no fixing member 70 is attached to the insertion portion 23.

[0060] As shown in Figure 8, the inner circumferential surface of the second insertion hole 64 includes a pivot point 64a, a first guide portion 64b, and a second guide portion 64c. The pivot point 64a is located in the central part of the second insertion hole 64 in the axial direction. The first guide portion 64b is located continuously below the pivot point 64a. The second guide portion 64c is located continuously above the pivot point 64a.

[0061] The pivot point 64a is in contact with both sides of the outer circumferential surface of the insertion portion 23 in the Y-axis direction. More specifically, the pivot point 64a is in contact with the outer circumferential surface of the insertion portion 23 around its entire circumference. That is, the diameter of the pivot point 64a is the same as the diameter of the insertion portion 23.

[0062] The first guide portion 64b has a first gap G1 between itself and the insertion portion 23 that allows the cymbal pad 15 to swing, on one side of the insertion portion 23 in the Y-axis direction, i.e., behind the insertion portion 23. The first gap G1 is provided on the side of the insertion portion 23 where the striking portion 40 is located. When viewed from the Z-axis direction, the first gap G1 is, for example, semi-circular in shape. The size of the first gap G1 decreases towards the pivot point portion 64a. The entire portion of the first guide portion 64b, excluding the portion that forms the first gap G1, is in contact with the outer circumferential surface of the insertion portion 23.

[0063] The second guide portion 64c has a second gap G2 between itself and the insertion portion 23 that allows the cymbal pad 15 to swing, on the other side of the insertion portion 23 in the Y-axis direction, i.e., in front of the insertion portion 23. The second gap G2 is provided on the side of the insertion portion 23 opposite to the striking portion 40. When viewed from the Z-axis direction, the second gap G2 is, for example, semi-circular in shape. The size of the second gap G2 decreases towards the pivot point portion 64a. The entire portion of the second guide portion 64c, excluding the portion that forms the second gap G2, is in contact with the outer circumferential surface of the insertion portion 23.

[0064] As shown in Figures 5 and 8, the upper surface of the cover-side flange portion 62 is provided with a second restricting surface 62a, which is contacted from above by a restricting portion 77, described later. The second restricting surface 62a is formed in the shape of a rectangular frame so as to surround the outer peripheral edge of the base end of the protrusion 63 (see Figure 4). The second restricting surface 62a is located above the other parts of the upper surface of the cover-side flange portion 62. The second restricting surface 62a is continuous with the curved surface 63a of the protrusion 63 and the pair of first restricting surfaces 63b.

[0065] (Configuration of the fixing member 70) The fixing member 70 is fixed to the insertion part 23, specifically to the portion of the insertion part 23 that protrudes above the cymbal pad 15.

[0066] The fixing member 70 has a fitting hole 71 into which the insertion portion 23 is fitted. The fitting hole 71 penetrates the fixing member 70 in the Z-axis direction. As shown in Figure 6, the fixing member 70 has a pair of clamping parts 73 that grip the insertion part 23 and a tightening part 74 that tightens the pair of clamping parts 73.

[0067] The pair of clamping portions 73 form a fitting hole 71 and a slit 72 connected to the fitting hole 71. The slit 72 extends along the entire Z-axis direction of the fixing member 70. The fastening portion 74 includes a bolt 75 that passes through a pair of clamping portions 73 in the X-axis direction, and a nut 76 embedded in one of the pair of clamping portions 73. The fastening portion 74 can change the amount of tightening of the insertion portion 23 in the pair of clamping portions 73 by changing the amount the bolt 75 is screwed into the nut 76.

[0068] As shown in Figure 5, the fixing member 70 has a restricting portion 77 into which the protrusion 63 is locked. The restricting portion 77 is integrally provided at the lower part of the pair of clamping portions 73. The restricting portion 77 is provided with a recess 78 into which the protrusion 63 fits and locks, thereby restricting the rotation of the cymbal pad 15 around the insertion portion 23. The recess 78 opens to the lower end surface of the fixing member 70. The recess 78 communicates with the fitting hole 71. The recess 78 is an example of a "locked portion".

[0069] As shown in Figures 5, 7, and 8, the inner surface of the recess 78 has a shape that conforms to the outer surface of the protrusion 63. The inner surface of the recess 78 includes a first contact surface 78a and a pair of second contact surfaces 78b.

[0070] As shown in Figure 8, the first contact surface 78a curves and extends along the curved surface 63a and contacts the curved surface 63a. A fitting hole 71 is opened in the first contact surface 78a. As shown in Figure 7, a slit 72 is formed in a part of the first contact surface 78a.

[0071] As shown in Figure 5, the pair of second contact surfaces 78b extend planarly along the pair of first restricting surfaces 63b and contact the pair of first restricting surfaces 63b respectively. The pair of second contact surfaces 78b are continuous with both side edges of the first contact surface 78a in the X-axis direction. The second contact surface 78b is an example of a "contact surface".

[0072] As shown in Figure 7, the restricting portion 77 has a pair of side walls 79 that each constitute a pair of second contact surfaces 78b. The thickness of the rear end of each side wall 79 decreases towards the slit 72 in the Y-axis direction, that is, towards the rear. Therefore, before the pair of clamping portions 73 are tightened by the clamping portion 74, a gap is formed between each second contact surface 78b and the first restricting surface 63b. Although not shown in the figure, as the pair of clamping portions 73 are tightened by the clamping portion 74, each side wall 79 deforms toward the first restricting surface 63b, so that the entirety of each second contact surface 78b comes into contact with the first restricting surface 63b. Consequently, the recess 78 comes into contact with the convex portion 63 on both sides in the circumferential direction centered on the second insertion hole 64. As a result, the pair of first restricting surfaces 63b and the pair of second contact surfaces 78b come into contact, restricting the rotation of the cymbal pad 15 around the insertion portion 23.

[0073] As shown in Figure 5, the fixing member 70 is fixed to the insertion portion 23 by the tightening portion 74, which tightens the pair of clamping portions 73 when the insertion portion 23 is inserted into the fitting hole 71. With the convex portion 63 locked into the concave portion 78, the lower end surface of the restricting portion 77 is in contact with the second restricting surface 62a from above.

[0074] The fixing member 70 is configured to be switchable between a fixed state in which it is attached to the insertion portion 23 so as not to move relative to it, and an unfixed state in which it is attached so as to be movable relative to the insertion portion 23, by changing the amount of tightening by the fastening portion 74. In the unfixed state, the fixing member 70 is slidable along the insertion portion 23 in the Z-axis direction. In addition, in the unfixed state, the fixing member 70 is rotatable with respect to the insertion portion 23 together with the cymbal pad 15, with the convex portion 63 fitted into the concave portion 78.

[0075] (Configuration of the receiving member 80) The receiving member 80 is attached to the insertion part 23 at a position lower than the cymbal pad 15. The receiving member 80 supports the cymbal pad 15 from below. The receiving member 80 is formed of, for example, a resin material.

[0076] The receiving member 80 has a cylindrical tube portion 81 and an umbrella portion 82 extending outward from the upper end of the tube portion 81. The tube portion 81 has a first through hole 83 through which the insertion portion 23 passes. The receiving member 80 is supported from below by a pin 100 that penetrates the insertion portion 23 in the X-axis direction. More specifically, both sides of the lower end of the cylindrical portion 81 in the X-axis direction are supported from below by the ends of the pin 100 that protrude from the insertion portion 23.

[0077] The umbrella portion 82 is curved in a dome shape so that it is located lower the further it is from the outer circumference of the cylindrical portion 81. (Structure of the elastic member 90) The elastic member 90 is installed between the receiving member 80 and the cymbal pad 15 in the insertion portion 23. The elastic member 90 is pressed against the receiving member 80 by the cymbal pad 15. The elastic member 90 supports the cymbal pad 15 from below.

[0078] The elastic member 90 is cylindrical. The elastic member 90 is made of, for example, felt. The elastic member 90 has a second through-hole 91 through which the insertion portion 23 passes. The second through-hole 91 communicates with the second insertion hole 64 and the first through-hole 83.

[0079] (The oscillation pattern of the cymbal pad 15) As shown in Figure 8, the cymbal pad 15 extends cantileveredly backward from the insertion portion 23. Furthermore, the second insertion hole 64 is provided with a first guide portion 64b and a second guide portion 64c. Therefore, when the fixing member 70 is removed from the insertion portion 23, the cymbal pad 15 can move relative to the insertion portion 23 within the range of the first gap G1 and the second gap G2. As a result, the cymbal pad 15 sags due to its own weight. However, when the fixing member 70 is fixed to the insertion portion 23, the elastic member 90 presses the second restricting surface 62a against the lower end surface of the restricting portion 77. This restricts the sagging of the cymbal pad 15. Therefore, the posture of the cymbal pad 15 is maintained in a horizontal position.

[0080] As shown in Figure 9, when the striking part 40 is struck from above, the cymbal pad 15 rotates downward around the pivot point 64a while compressing the elastic member 90 downward. As the cymbal pad 15 rotates, the first guide part 64b fills the first gap G1 that was located behind the insertion part 23, and a gap G11 is formed in front of the insertion part 23. At the same time, the second guide part 64c fills the second gap G2 that was located in front of the insertion part 23, and a gap G21 is formed behind the insertion part 23. At this time, the first guide part 64b contacts the insertion part 23 from the rear, and the second guide part 64c contacts the insertion part 23 from the front. As a result, the downward rotation of the cymbal pad 15 is restricted.

[0081] When the cymbal pad 15 rotates downward, the protrusion 63 moves so that the curved surface 63a retracts from the first contact surface 78a. The first contact surface 78a has the function of accommodating the curved surface 63a of the moving protrusion 63. Also, when the cymbal pad 15 rotates downward, a pair of second contact surfaces 78b slide against a pair of first restricting surfaces 63b in a plane direction perpendicular to the X-axis direction.

[0082] The cymbal pad 15, which has rotated downward, returns to its pre-impact position due to the restoring force of the elastic member 90. Therefore, striking the cymbal pad 15 causes it to oscillate.

[0083] (Adjusting the position of cymbal pad 15) As shown in Figure 10, the cymbal pad 15 is connected to the support column 11a via a bracket 30 and a support rod 20. By loosening the first tightening part 32 of the bracket 30, the bracket 30 can rotate around the entire circumference relative to the support column 11a. Similarly, by loosening the second tightening part 36 of the bracket 30, the support rod 20 can rotate around the entire circumference relative to the bracket 30. Furthermore, by disengaging the fixing member 70, the cymbal pad 15 can rotate around the entire circumference relative to the support rod 20. Therefore, by rotating at least one of the bracket 30, the support rod 20, and the cymbal pad 15, the position of the cymbal pad 15 relative to the support column 11a can be changed to any desired position.

[0084] The following describes the first, second, third, and fourth positions shown in Figures 10-13 as examples of arbitrary positions that the cymbal pad 15 can take. When the cymbal pad 15 is in the first, second, third, and fourth positions, the striking surface 40 of the cymbal pad 15 faces the performer in the Y-axis direction. By changing the position of the cymbal pad 15 between the first, second, third, and fourth positions, the performer can gradually change the distance between the cymbal pad 15 and the performer in the Y-axis direction.

[0085] As shown in Figure 10, the first position is the position where the cymbal pad 15 is furthest forward from the support column 11a. When the cymbal pad 15 is in the first position, both the base portion 21 and the insertion portion 23 are located in front of the support column 11a. Also, at this time, the second tightening portion 36 is located in front of the support column 11a.

[0086] As shown in Figure 11, the second position is a position in which the cymbal pad 15 is located further back than the first position. When the cymbal pad 15 is in the second position, the base 21 is located further back than the support column 11a, and the insertion portion 23 is located further forward than the support column 11a.

[0087] With the cymbal pad 15 in the first position, the cymbal pad 15 can be moved to the second position by rotating the bracket 30 and the support rod 20. More specifically, with the cymbal pad 15 in the first position, first, rotate the bracket 30 relative to the support rod 11a so that the second clamping portion 36 is positioned behind the support rod 11a. Then, rotate the support rod 20 relative to the bracket 30 so that the insertion portion 23 is positioned in front of the support rod 11a, thereby moving the cymbal pad 15 to the second position.

[0088] As shown in Figure 12, the third position is a position in which the cymbal pad 15 is located further back than the second position. When the cymbal pad 15 is in the third position, the base 21 is located in front of the support column 11a and the insertion portion 23 is located behind the support column 11a.

[0089] With the cymbal pad 15 in the first position, the cymbal pad 15 can be moved to the third position by rotating the support rod 20 and the cymbal pad 15 simultaneously. More specifically, first, the support rod 20 is rotated relative to the bracket 30 so that the insertion part 23 is positioned behind the support column 11a. Then, the cymbal pad 15 can be moved to the third position by rotating the cymbal pad 15 relative to the support rod 20 so that the striking part 40 is positioned behind the insertion part 23.

[0090] As shown in Figure 13, the fourth position is a position where the cymbal pad 15 is located further back than the third position, and is the position where the cymbal pad 15 is furthest back from the support column 11a. When the cymbal pad 15 is in the fourth position, both the base portion 21 and the insertion portion 23 are located further back than the support column 11a.

[0091] With the cymbal pad 15 in the first position, the cymbal pad 15 can be moved to the fourth position by rotating the bracket 30 and the cymbal pad 15 simultaneously. More specifically, with the cymbal pad 15 in the first position, first, the bracket 30 is rotated relative to the support column 11a so that the second clamping portion 36 is positioned behind the support column 11a. Then, the cymbal pad 15 can be moved to the fourth position by rotating the cymbal pad 15 relative to the support rod 20 so that the striking portion 40 is positioned behind the insertion portion 23.

[0092] Furthermore, by loosening the first tightening part 32, the height position of the bracket 30 relative to the support column 11a can be changed. Also, by loosening the second tightening part 36, the height position of the support rod 20 relative to the bracket 30 can be changed. Therefore, the height position of the cymbal pad 15 can also be changed as desired.

[0093] <Operation of this embodiment> In this embodiment of the cymbal pad 15, the convex portion 63 engages with the recess 78 of the fixing member 70 when it is fixed, thereby restricting the rotation of the cymbal pad 15 around the support rod 20.

[0094] To adjust the orientation of the cymbal pad 15 relative to the performer, the performer first loosens the tightening portion 74 to switch the fixing member 70 from a fixed state to an unfixed state. This allows the fixing member 70 to move relative to the support rod 20. Then, while maintaining the state in which the convex portion 63 and concave portion 78 are engaged, the performer rotates the fixing member 70 together with the cymbal pad 15 relative to the support rod 20 to change the orientation of the cymbal pad 15 to the desired orientation. Finally, the performer switches the fixing member 70 from an unfixed state to a fixed state by tightening the pair of clamping portions 73 with the tightening portion 74.

[0095] <Effects of this embodiment> (1) The fixing member 70 is fixed to the insertion portion 23 of the support rod 20. The fixing member 70 is configured to be switchable between a fixed state in which it is attached to the support rod 20 so as not to move relative to it, and an unfixed state in which it is attached so as to be movable relative to the support rod 20. A protrusion 63 is provided on the upper surface of the cymbal pad 15. The fixing member 70 is provided with a recess 78 that restricts the rotation of the cymbal pad 15 around the support rod 20 by engaging the protrusion 63.

[0096] According to the above configuration, the fixing member 70 is fixed to the insertion portion 23 of the support rod 20. Therefore, when adjusting the orientation of the cymbal pad 15, the performer can switch the fixing member 70 between the fixed and unfixed states while checking from above the cymbal pad 15. As a result, the performer can operate the fixing member 70 without significantly changing their posture, such as by peering at the cymbal pad 15 from below. Thus, the process of adjusting the orientation of the cymbal pad 15 relative to the performer can be easily performed.

[0097] Furthermore, with the above configuration, the protrusion 63 fits into the recess 78, thereby locking the protrusion 63 and the recess 78 together. This makes it easier for the performer to confirm from above the cymbal pad 15 that the protrusion 63 is fitted into the recess 78.

[0098] Furthermore, for example, if a recess 78 is formed in the cymbal pad 15 and a protrusion 63 is formed in the fixing member 70, it is necessary to ensure sufficient thickness in the cymbal pad 15 to form the recess 78. This may limit the shape of the cymbal pad 15.

[0099] In this respect, the above configuration allows for greater freedom in the shape of the cymbal pad 15 compared to a configuration in which a recess 78 is formed in the cymbal pad 15 and a protrusion 63 is formed in the fixing member 70.

[0100] (2) The second insertion hole 64 penetrates the protrusion 63. The outer surface of the protrusion 63 includes the first restricting surface 63b. The inner surface of the recess 78 includes a second contact surface 78b that extends along the first restricting surface 63b and contacts the first restricting surface 63b.

[0101] With the above configuration, since the second insertion hole 64 penetrates the protrusion 63, the protrusion 63 and the insertion portion 23 of the support rod 20 are located on the same axis. Therefore, by attaching the fixing member 70 to the insertion portion 23, the protrusion 63 fits into the recess 78. As a result, the first restricting surface 63b and the second contact surface 78b come into contact, restricting the rotation of the cymbal pad 15. Therefore, the work of attaching the fixing member 70 to the support rod 20 and the work of locking the protrusion 63 and the recess 78 can be performed simultaneously or continuously. Thus, the work of fixing the cymbal pad 15 to the support rod 20 can be performed smoothly.

[0102] (3) The cymbal pad 15 comprises a case body 42 and a cover 60. The case body 42 houses the striking part 40. The cover 60 is made of an elastic material. The cover 60 forms a protrusion 63 and is attached to the case body 42.

[0103] According to the above configuration, the cover 60 attached to the case body 42 constitutes the protrusion 63, and the support rod 20 inserted into the second insertion hole 64 of the protrusion 63 penetrates the cover 60. Therefore, the cover 60, made of an elastic material, is interposed between the case body 42 and the support rod 20, and between the case body 42 and the fixing member 70. This makes it possible to suppress the generation of contact noise between the cymbal pad 15 and the support rod 20, and between the cymbal pad 15 and the fixing member 70 when the cymbal pad 15 is struck.

[0104] Furthermore, with the above configuration, it is possible to suppress the vibrations caused by the impact of the striking part 40 being transmitted to other pads in the electronic drum set 10, which would cause the vibration sensors of those other pads to react. Moreover, even if the vibrations caused by the impact of the other pads are transmitted to the support rod 20, the vibrations are absorbed by the cover 60, thereby suppressing their transmission to the vibration sensor 51 of the cymbal pad 15.

[0105] (4) The outer surfaces of the protrusion 63 on both sides in the X-axis direction are formed by a planar first restricting surface 63b extending in the Y-axis direction. Viewed from the Z-axis direction, the impact surface 40a is provided alongside the protrusion 63 in the Y-axis direction. A first gap G1 and a second gap G2 are provided between the outer surface of the support rod 20 and the inner surface of the second insertion hole 64 to allow the cymbal pad 15 to swing.

[0106] According to the above configuration, a first gap G1 and a second gap G2 are provided between the outer circumferential surface of the support rod 20 and the inner circumferential surface of the second insertion hole 64, allowing the cymbal pad 15 to swing. Here, the portions of the outer surface of the protrusion 63 on both sides in the X-axis direction are formed by a first restricting surface 63b. Since the first restricting surface 63b is in contact with the second contact surface 78b of the fixing member 70 in the X-axis direction, the X-axis direction end of the cymbal pad 15 is restricted from swinging up and down. On the other hand, since the first restricting surface 63b is planar and extends in the Y-axis direction, the sliding of the first restricting surface 63b with the second contact surface 78b allows the Y-axis direction end of the cymbal pad 15 to swing up and down. Therefore, the performer can play the cymbal pad 15 while swinging it up and down by striking the striking surface 40a, which is aligned with the protrusion 63 in the Y-axis direction when viewed from the Z-axis direction.

[0107] (5) The pivot point 64a contacts both sides of the outer circumferential surface of the support rod 20 in the Y-axis direction. The first guide portion 64b has a first gap G1 between it and the support rod 20 at the rear of the support rod 20, which allows the cymbal pad 15 to swing. The second guide portion 64c has a second gap G2 between it and the support rod 20 at the front of the support rod 20, which allows the cymbal pad 15 to swing. The portion of the first guide portion 64b excluding the portion that forms the first gap G1 and the portion of the second guide portion 64c excluding the portion that forms the second gap G2 are in contact with the outer circumferential surface of the support rod 20.

[0108] According to the above configuration, the first guide portion 64b, provided below the pivot portion 64a, has a first gap G1 between it and the support rod 20. The second guide portion 64c, provided above the pivot portion 64a, has a second gap G2 between it and the support rod 20. Therefore, when a performer strikes the striking surface 40a of the cymbal pad 15 from above, the cymbal pad 15 rotates around the pivot portion 64a as a pivot point. As this rotation occurs, the first guide portion 64b moves from rear to front to fill the first gap G1 and contacts the support rod 20. At the same time, the second guide portion 64c moves from front to rear to fill the second gap G2 and contacts the support rod 20. In this state, before the striking surface 40a is struck, the portion of the first guide portion 64b excluding the portion that forms the first gap G1 and the portion of the second guide portion 64c excluding the portion that forms the second gap G2 are in contact with the outer circumferential surface of the support rod 20. Therefore, in addition to the first regulating surface 63b and the second contact surface 78b, the first guide portion 64b and the second guide portion 64c guide the oscillation of the cymbal pad 15 so that one end of the cymbal pad 15 in the Y-axis direction swings up and down. Consequently, the oscillation of the cymbal pad 15 becomes more stable.

[0109] (6) The elastic member 90 supports the cymbal pad 15 from below. With the above configuration, the cymbal pad 15 is supported from below by the elastic member 90, thereby positioning the cymbal pad 15 along the length of the support rod 20. Furthermore, when the cymbal pad 15 is struck, the elastic member 90 elastically deforms, causing the cymbal pad 15 to oscillate. Therefore, the performer can play while making the cymbal pad 15 oscillate.

[0110] (7) The fixing member 70 is configured to change the fixing position in the longitudinal direction of the support rod 20. With the above configuration, the degree to which the cymbal pad 15 is pressed against the elastic member 90 can be adjusted by changing the fixing position of the fixing member 70 in the longitudinal direction of the support rod 20. This makes it possible to adjust the degree of oscillation of the cymbal pad 15.

[0111] (8) The fixing member 70 has a pair of clamping parts 73 that grip the support rod 20 and a fastening part 74 that tightens the pair of clamping parts 73. For example, in a configuration where the fixing member 70 is fixed to the support rod 20 by the engagement of a male screw formed on the support rod 20 and a female screw formed on the fixing member 70, if a force acts on the cymbal pad 15 in the circumferential direction of the second insertion hole 64 during playing, the engagement between the male screw and the female screw may loosen. In this case, the orientation of the cymbal pad 15 relative to the performer may change during playing.

[0112] In this regard, with the above configuration, the fixing member 70 is attached to the support rod 20 so that it cannot move relative to the support rod 20 by tightening the pair of clamping parts 73, which are sandwiching the support rod 20, with the tightening part 74. Therefore, even if a force acts on the cymbal pad 15 in the circumferential direction of the second insertion hole 64, the tightening force of the tightening part 74 is less likely to decrease. Consequently, the orientation of the cymbal pad 15 relative to the performer is less likely to change during performance.

[0113] (9) The support rod 20 has a base portion 21 extending vertically, an offset portion 22 extending from the base portion 21 in a direction different from the longitudinal direction of the base portion 21, and an insertion portion 23 extending upward from the offset portion 22. The bracket 30 has a pair of first clamping portions 31 that clamp the support column 11a, a first tightening portion 32 that tightens the pair of first clamping portions 31, a pair of second clamping portions 35 that clamp the base portion 21, and a second tightening portion 36 that tightens the pair of second clamping portions 35. The pair of first clamping portions 31 form a first holding hole 31a that holds the support column 11a. The pair of second clamping portions 35 form a second holding hole 35a that holds the base portion 21. The central axis L1 of the first holding hole 31a is along the central axis L2 of the second holding hole 35a.

[0114] According to the above configuration, the central axis L1 of the first holding hole 31a of the first clamping portion 31 aligns with the central axis L2 of the second holding hole 35a of the second clamping portion 35. Therefore, the support column 11a and the support rod 20 extending along the support column 11a can be connected by the bracket 30.

[0115] Furthermore, by loosening the tightening of the pair of first clamping parts 31 by the first tightening part 32 and rotating the bracket 30, the position of the bracket 30 relative to the support column 11a can be changed. In addition, by loosening the tightening of the pair of second clamping parts 35 by the second tightening part 36 and rotating the support rod 20, the position of the support rod 20 relative to the bracket 30 can be changed. Here, since the support rod 20 has an offset part 22, by rotating the support rod 20 relative to the bracket 30, the position of the insertion part 23 relative to the support column 11a, that is, the position of the cymbal pad 15 relative to the support column 11a, changes. From the above, by combining the rotation of the bracket 30 relative to the support column 11a and the rotation of the support rod 20 relative to the bracket 30, the degree of freedom in adjusting the position of the cymbal pad 15 relative to the support column 11a can be increased. Therefore, the distance between the performer and the cymbal pad 15 can be suitably adjusted.

[0116] <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.

[0117] The impacted area 40 may be made of an elastic material such as rubber instead of sponge. As shown in Figure 14, the lower end surface of the restricting portion 77 may have a flat surface 77a perpendicular to the Z-axis direction and an inclined surface 77b inclined with respect to the flat surface 77a. The flat surface 77a and the inclined surface 77b constitute one and the other parts of the lower end surface of the restricting portion 77 with respect to the center of the arc of the curved surface 63a in the Y-axis direction. The inclined surface 77b is inclined with respect to the flat surface 77a such that it moves further away from the flat surface 77a in the Y-axis direction and toward the clamping portion 73 in the Z-axis direction. When the fixing member 70 is fixed to the support rod 20 such that the inclined surface 77b is located in front of the flat surface 77a, the posture of the cymbal pad 15 is maintained in a state where the second restricting surface 62a is in contact with the inclined surface 77b, that is, in a state where the cymbal pad 15 hangs down due to its own weight. At this time, the second restricting surface 62a is not in contact with the flat surface 77a. When the cymbal pad 15 is struck, the cymbal pad 15 swings smoothly as the curved surface 63a and the first contact surface 78a slide against each other with the center of the arc of the curved surface 63a coinciding with the center of the arc of the first contact surface 78a. Alternatively, as shown in Figure 15, the fixing member 70 may be fixed to the support rod 20 such that the inclined surface 77b is positioned behind the flat surface 77a. In this case, the second restricting surface 62a contacts the flat surface 77a, maintaining the cymbal pad 15 in a horizontal position. Therefore, the cymbal pad 15 can be swung in the same manner as in the above embodiment.

[0118] In this embodiment, an example has been described in which the cymbal pad support structure is applied to the cymbal pad 15 that constitutes the electronic drum set 10. However, the cymbal pad support structure can also be applied to a practice cymbal pad that does not have a vibration sensor 51.

[0119] The offset portion 22 may extend linearly from the base portion 21 in a direction perpendicular to the base portion 21. The offset portion 22 does not have to extend in a straight line. The offset portion 22 may extend by bending multiple times.

[0120] • A support column 11a may be inserted into the second insertion hole 64 instead of the support rod 20. In this case, the cymbal pad 15 is supported by the stand 11 by fixing the fixing member 70 to the support column 11a. In this modified example, the support column 11a corresponds to the "support rod".

[0121] The central axis L1 of the first retaining hole 31a and the central axis L2 of the second retaining hole 35a do not have to extend strictly parallel to each other. The central axes L1 and L2 may extend generally parallel to each other within the range that achieves the effects of this embodiment.

[0122] The fastening portion 74 does not necessarily have to include a nut 76. The fastening portion 74 may consist of a bolt 75 inserted into one of the pair of clamping portions 73 and a female thread formed on the other of the pair of clamping portions 73. This modification can also be applied similarly to the first fastening portion 32 and the second fastening portion 36 of the bracket 30.

[0123] The fixing member 70 does not necessarily have to be configured to allow changes in its fixing position relative to the support rod 20. The fixing member 70 may be attached to the support rod 20 in a predetermined position so as not to move relative to the support rod 20 by engaging with the support rod 20.

[0124] The elastic member 90 may be made of an elastic material other than felt, such as rubber. The receiving member 80 may be made of an elastic material such as rubber. In this case, the elastic member 90 may be omitted, and the cymbal pad 15 may be directly supported from below by the receiving member 80. In this configuration, since the receiving member 80 corresponds to the "elastic member," it is possible to achieve an effect similar to the effect (6) described above.

[0125] The second insertion hole 64 does not necessarily have to have the first guide portion 64b and the second guide portion 64c. Even in this case, the cymbal pad 15 becomes swingable due to the elastic deformation of the elastic member 90 and the protrusion 63.

[0126] The protrusion 63 may be formed separately from the cover-side flange 62. The first restricting surface 63b may be inclined with respect to the Z-axis direction. For example, a pair of first restricting surfaces 63b may be inclined with respect to the Z-axis direction such that they move closer to each other in the X-axis direction as they extend upward.

[0127] The outer surface of the protrusion 63 may have a single first restricting surface 63b. The outer surface of the protrusion 63 does not have to have a curved surface 63a. In this case, the first contact surface 78a does not have to be curved.

[0128] The protrusions 63 are not limited to those that form the second insertion hole 64. For example, multiple protrusions 63 may be provided around the second insertion hole 64 formed on the upper surface of the cover-side flange portion 62. In this case, it is preferable that the fixing member 70 has multiple recesses 78 into which each of the multiple protrusions 63 fits. Even with this configuration, the rotation of the cymbal pad 15 around the support rod 20 is restricted by the multiple protrusions 63 engaging with the multiple recesses 78.

[0129] The cymbal pad 15 may have a recess 78, and the fixing member 70 may have a protrusion 63. The projection protruding from the upper surface of the cover-side flange portion 62 may engage with the outer surface of the fixing member 70 in the circumferential direction of the second insertion hole 64. Even in this case, since the rotation of the cymbal pad 15 is restricted, the performer can visually confirm the engagement of the cymbal pad 15 with the fixing member 70. [Explanation of Symbols]
