Summary of the Invention

Problems to be Solved by the Invention

[0005] In the stand described in Patent Document 1, when a performer unfolds the stand, they rotate the right side frame away from the left side frame and then tighten the clamp with a handle. At this time, the performer needs to adjust the rotation angle of the right side frame to the desired rotation angle. As a result, if the stand is repeatedly unfolded and folded, the relative positions of the support columns may vary, making it difficult to reproduce the shape of the stand.

[0006] Furthermore, in a stand designed to be foldable, it is preferable that the stand does not become large when folded, which is important for packaging and storage. However, in the stand described in Patent Document 1, the distance between the central support and the left support, and the distance between the central support and the right support, do not change before and after folding. Therefore, there are inherent limitations in suppressing the increase in size of the stand when folded. Moreover, if the left and right side frames are removed from the respective support columns in order to suppress the increase in size of the stand when folded, not only is reassembly time-consuming, but the positional relationship between the support columns may become even more difficult to reproduce.

[0007] Therefore, it is desirable to achieve both improved reproducibility of the stand's shape in the unfolded state and suppression of the stand's size increase in the folded state. [Means for solving the problem]

[0008] This document describes a percussion instrument stand designed to address the above-mentioned problems. [Aspect 1] A stand for supporting a percussion instrument, comprising: a first support column extending vertically and installed on a mounting surface; a pair of second support columns extending along the first support column and installed on the mounting surface; and a pair of arms connecting the first support column and the pair of second support columns, respectively, wherein the first support column and the pair of second support columns are arranged such that, when viewed from above, the line segment connecting the central axis of the first support column and the central axes of each of the pair of second support columns forms a triangle; each of the pair of arms is rotatably supported relative to the first support column and the second support column about an axis extending horizontally; and the pair of second support columns are configured to be unfoldable and foldable relative to the first support column by the rotation of the pair of arms.

[0009] According to the above configuration, when the pair of second pillars are unfolded and folded relative to the first pillar, each arm rotates relative to the first and second pillars around its horizontally extending axis. Therefore, it is possible to suppress changes in the opening angle of the pair of arms as viewed from above and below before and after the unfolding of the pair of second pillars. This suppresses variations in the position of the pair of second pillars relative to the first pillar after the unfolding of the pair of second pillars. As a result, even when the unfolding of the pair of second pillars is repeated, the shape and size of the triangle formed by the line segment connecting the central axis of the first pillar and the central axes of each second pillar, as viewed from above and below, are less likely to change.

[0010] Furthermore, according to the above configuration, the pair of second support columns are folded relative to the first support column by the rotation of the pair of arms. Since each second support column is rotatably supported relative to the arms, the stand can be folded so that the pair of second support columns are aligned with the first support column.

[0011] Based on the above, it is possible to achieve both improved reproducibility of the stand's shape in the unfolded state and suppression of the stand's size increase in the folded state. [Aspect 2] The percussion instrument stand according to [Aspect 1], wherein the arm is a first arm, and the first support column and the pair of second support columns are connected at positions different from the pair of first arms in the longitudinal direction of the first support column, and a pair of second arms are provided extending along the pair of first arms, and each of the pair of second arms is rotatably supported with respect to the first support column and the second support column about an axis extending in the horizontal direction.

[0012] According to the above configuration, each second support column is connected to the first support column by the first arm and the second arm. This makes it easier to stabilize the posture of the pair of second support columns. Therefore, the reproducibility of the stand's shape in the deployed state can be improved.

[0013] [Aspect 3] The percussion instrument stand according to [Aspect 1] or [Aspect 2], wherein the first support column and the pair of second support columns extend parallel to each other, and the pair of first arms and the pair of second arms extend parallel to each other.

[0014] According to the above configuration, the pair of first arms and the pair of second arms rotate relative to the first support column, allowing the pair of second support columns to be deployed and folded while maintaining a position parallel to the first support column. Therefore, the reproducibility of the stand's shape in the deployed state can be improved.

[0015] [Aspect 4] A percussion instrument stand according to any one of [Aspect 1] to [Aspect 3], comprising a slider configured to slide in the longitudinal direction of the first support column, and a pair of stays connecting the slider to the pair of first arms or the pair of second arms, wherein each of the pair of stays is rotatably supported with respect to the slider and the first arm or the second arm about an axis extending in the horizontal direction, and the pair of second support columns are configured to unfold and fold relative to the first support column in conjunction with the sliding of the slider.

[0016] According to the above configuration, sliding the slider along the length of the first support column causes a pair of first arms or a pair of second arms connected to a pair of stays to rotate. This causes the pair of second support columns to be simultaneously extended and folded relative to the first support column. Therefore, the extension and folding of the pair of second support columns can be easily performed.

[0017] [Aspect 5] The percussion instrument stand according to [Aspect 4], wherein the pair of first arms connect the first support column and the pair of second support columns at a position above the pair of second arms, and the pair of stays connect the slider and the pair of first arms, respectively.

[0018] According to the above configuration, the first arms, which are connected to the first and second support columns at a position above each second arm, are supported by stays. Therefore, compared to the case where each stay is connected to the second arm, each stay can receive the load of the percussion instrument supported by each second support column at a higher position. Consequently, the stability of the percussion instrument stand is improved.

[0019] [Aspect 6] The percussion instrument stand according to any one of [Aspect 1] to [Aspect 5], wherein the first support column is positioned further back than the pair of second support columns when viewed from the perspective of the percussion instrument player.

[0020] According to the above configuration, a space is formed at the performer's feet, enclosed by the first support and a pair of second support pillars. Therefore, this space can be used to place percussion instruments such as a bass drum.

[0021] [Aspect 7] The percussion instrument stand according to [Aspect 6], wherein the vertical length of each of the pair of second support columns is shorter than the vertical length of the first support column. According to the above configuration, when a performer plays a percussion instrument supported by the first support, the second support can be prevented from interfering with the performance.

[0022] [Aspect 8] A percussion instrument stand according to [Aspect 6] or [Aspect 7], comprising an attachment member attached to the first support column and to which a bass drum pad, which is one of the percussion instruments, is attached.

[0023] According to the above configuration, when the bass drum pad is attached to the attachment member, the movement of the bass drum pad approaching the first support column due to the impact during the striking of the bass drum pad is restricted. Thereby, it is possible to suppress a change in the relative position between the bass drum pad and other percussion instruments. Also, a separate structure for fixing the bass drum pad to the installation surface is not required.

[0024] [Aspect 9] A percussion instrument stand according to any one of [Aspect 1] to [Aspect 8], comprising a support bar for supporting the percussion instrument and a bracket attached to one of the first support column and one of the pair of second support columns and holding the support bar, wherein the bracket is configured to be detachable via the upper end portion of the support column.

[0025] For example, when attaching the bracket to a connecting arm that connects the first support column and the second support column, since the end portion of the connecting arm is connected to the first support column or the second support column, it is difficult to attach and detach the bracket via the end portion of the connecting arm.

[0026] In this regard, according to the above configuration, the bracket is detachable via the upper end portion of one of the first support column and one of the pair of second support columns. Therefore, the attachment and detachment of the bracket can be easily performed. Thus, the attachment and detachment of the percussion instrument to the percussion instrument stand can be easily performed.

[0027] [Aspect 10] A percussion instrument stand according to any one of [Aspect 1] to [Aspect 9], wherein the first support column has a support portion that rotatably supports the pair of arms, and the support portion has an attachment portion configured to be able to attach a sound source device that emits sound based on an output signal of a vibration sensor provided on the percussion instrument.

[0028] According to the above configuration, if the percussion instrument is an electronic percussion instrument equipped with a vibration sensor, it is not necessary to prepare a separate part for attaching the sound source device to the percussion instrument stand, in addition to the support part. Therefore, it is possible to suppress an increase in the number of parts that make up the percussion instrument stand. [Effects of the Invention]

[0029] According to the present invention, it is possible to achieve both improved reproducibility of the stand's shape in the unfolded state and suppression of an increase in the stand's size in the folded state. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0031] The following describes one embodiment in which a percussion instrument stand is used as a stand to support multiple pads that make up an electronic drum set, with reference to Figures 1 to 10. (Overall configuration of the 10-piece electronic drum set) The electronic drum set 10 includes 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, and two cymbal pads 15b and 15c. Each pad is an example of a "percussion instrument".

[0032] 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).

[0033] 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.

[0034] (Composition of Stand 11) As shown in Figure 2, the stand 11 comprises a first support column 20, a pair of second support columns 30, a pair of first arms 40, and a pair of second arms 50.

[0035] The first support column 20 extends linearly in the vertical direction and is installed on the installation surface FL. The first support column 20 has a first leg portion 21 provided at its lower end and in contact with the installation surface FL.

[0036] Each second support column 30 extends linearly in the vertical direction along the first support column 20 and is installed on the installation surface FL. Each second support column 30 has a second leg portion 31 provided at its lower end and in contact with the installation surface FL.

[0037] The first support column 20 and the pair of second support columns 30 extend parallel to each other. The vertical length of each second support column 30 is shorter than the vertical length of the first support column 20. As shown in Figure 4, the first support column 20 is positioned between the pair of second support columns 30, but further back than the pair of second support columns 30, as viewed from the performer P. The first support column 20 and the pair of second support columns 30 are positioned such that, when viewed from above, the line segment L connecting the central axis of the first support column 20 and the central axes of each second support column 30 forms a triangle. In this embodiment, the line segment L forms an isosceles triangle.

[0038] As shown in Figure 2, the first support column 20 has a first support portion 22 that rotatably supports one end of each first arm 40. The first support portion 22 is provided in the portion of the first support column 20 between the upper end and the lower end. The first support portion 22 is an example of a "support portion".

[0039] Each second support column 30 has a second support portion 32 that rotatably supports the other end of the first arm 40. The second support portion 32 is provided in the portion of the second support column 30 between the upper end and the lower end.

[0040] A pair of first arms 40 connect the first column 20 and the pair of second columns 30, respectively. Each first arm 40 extends in a straight line. One end of each first arm 40 is rotatably supported on the first support portion 22 of the first column 20 about a horizontally extending axis. The other end of each first arm 40 is rotatably supported on the second support portion 32 of the second column 30 about a horizontally extending axis.

[0041] The pair of second arms 50 connect the first support column 20 and the pair of second support columns 30 at positions different from those of the pair of first arms 40 in the longitudinal direction of the first support column 20. In this embodiment, the pair of first arms 40 connect the first support column 20 and the pair of second support columns 30 at a position higher than that of the pair of second arms 50. Each second arm 50 extends in a straight line. The length of each second arm 50 is the same as the length of each first arm 40. One end of each second arm 50 is rotatably supported on the first leg portion 21 of the first support column 20 about a horizontally extending axis. The other end of each second arm 50 is rotatably supported on the second leg portion 31 of the second support column 30 about a horizontally extending axis.

[0042] The pair of first arms 40 and the pair of second arms 50 extend parallel to each other. As described above, the first support column 20 and the pair of second support columns 30 extend parallel to each other. Therefore, the stand 11 constitutes a four-bar linkage mechanism with the first support column 20, the second support columns 30, and the first arms 40 and second arms 50 that connect the first and second support columns 20 and 30.

[0043] The stand 11 includes a slider 60 and a pair of stays 61. The slider 60 is configured to slide along the length of the first support column 20. The slider 60 slides along the portion of the first support column 20 between the first leg portion 21 and the first support portion 22.

[0044] A pair of stays 61 connect the slider 60 to a pair of first arms 40, respectively. One end of each stay 61 is rotatably supported relative to the slider 60 about a horizontally extending axis. The other end of each stay 61 is rotatably supported relative to the first arms 40 about a horizontally extending axis.

[0045] As shown in Figures 2 and 3, the pair of second support columns 30 are configured to be unfolded and folded relative to the first support column 20 by the rotation of the pair of first arms 40 in conjunction with the sliding of the slider 60 relative to the first support column 20. When the pair of second support columns 30 are folded, the slider 60 moves downward, unfolding the pair of second support columns 30 so that they move away from the first support column 20. When the pair of second support columns 30 are folded relative to the first support column 20, the slider 60 moves upward, folding the pair of second support columns 30 so that they move closer to the first support column 20. When the pair of second support columns 30 are folded relative to the first support column 20, the upper end of each second support column 30 is located above the upper end of the first support column 20, and the lower end of each second support column 30 is located above the lower end of the first support column 20. When the pair of second support columns 30 are extended and folded relative to the first support column 20, the pair of second support columns 30 move while maintaining a position parallel to the first support column 20.

[0046] The slider 60 is configured to be fixed to the first support column 20 at any position along its length by, for example, a clamping mechanism. The slider 60 becomes slidable relative to the first support column 20 by weakening the clamping force of the clamping mechanism.

[0047] The slider 60 is fixed to the first support column 20 when the pair of second support columns 30 are extended or folded, thereby restricting the movement of the pair of second support columns 30 relative to the first support column 20. This makes it easier to maintain the posture of the stand 11 when the pair of second support columns 30 are extended or folded. The clamping mechanism includes, for example, a configuration similar to that of the pair of first clamping parts 91 and first fastening parts 92 described later.

[0048] As shown in Figures 4 and 5, when the pair of second support columns 30 are unfolded and folded relative to the first support column 20, the shape of the triangle formed by the line segment L connecting the central axis of the first support column 20 and the central axes of each second support column 30 does not change when viewed from above, but the size of the triangle changes. That is, when the pair of second support columns 30 are unfolded and folded relative to the first support column 20, the opening angles of the pair of first arms 40 and the pair of second arms 50 do not change when viewed from above.

[0049] As shown in Figure 6, the stand 11 is equipped with a mounting member 70 to which the bass drum pad 12 is attached. The mounting member 70 is attached above the first leg portion 21 of the first support column 20.

[0050] As shown in Figure 7, the mounting member 70 is configured to accommodate a hook 12a extending upward from the bottom of the bass drum pad 12. The mounting member 70 has a protrusion 71 that supports the tip of the hook 12a from below. The bass drum pad 12 is attached to the mounting member 70 by hooking the hook 12a onto the protrusion 71 from above. A felt 12b is attached to the portion of the hook 12a that contacts the mounting member 70.

[0051] As shown in Figure 8, the stand 11 comprises six support rods 80a, 80b, 80c, 80d, 80e, and 80f, and six brackets 90a, 90b, 90c, 90d, 90e, and 90f that each hold one of the support rods 80a, 80b, 80c, 80d, 80e, and 80f.

[0052] As shown in Figures 1 and 8, support rod 80a supports the snare drum pad 13. Support rod 80b supports the floor tom pad 14a. Support rod 80c supports the first tom pad 14b and the second tom pad 14c. Support rod 80d supports the hi-hat cymbal pad 15a. Support rod 80e supports the cymbal pad 15b. Support rod 80f supports the cymbal pad 15c.

[0053] As shown in Figure 8, the bracket 90a is attached to the second support column 30 on the left side as viewed from the performer, and also holds the support rod 80a. The bracket 90a is attached to the portion of the left-side second support column 30 above the second support portion 32.

[0054] Bracket 90b is attached to the second support column 30 on the right side as viewed from the performer, and also holds the support rod 80b. Bracket 90b is attached to the right side of the second support column 30 above the second support portion 32.

[0055] The bracket 90c is attached to the first support column 20 and holds the support rod 80c. The bracket 90c is attached to the portion of the first support column 20 above the first support portion 22.

[0056] Bracket 90d is attached to the second support column 30 on the left side as viewed from the performer, and also holds the support rod 80d. Bracket 90d is attached to the left side of the second support column 30 above bracket 90a.

[0057] Bracket 90e is attached to the second support column 30 on the left side as viewed from the performer, and also holds the support rod 80e. Bracket 90e is attached to the left side of the second support column 30 above the portion of bracket 90d.

[0058] Bracket 90f is attached to the second support 30 on the right side as viewed from the performer, and also holds the support rod 80f. Bracket 90f is attached to the right-side second support 30 above bracket 90b.

[0059] As shown in Figure 9, the bracket 90f connects the second support column 30 and the support rod 80f. The bracket 90f has a pair of first clamping parts 91 that clamp the second support column 30 and a first tightening part 92 that tightens the pair of first clamping parts 91. The pair of first clamping parts 91 form a circular first holding hole 91a for holding the second support column 30 and a first slit 91b connected to the first holding hole 91a. The first tightening part 92 includes a first bolt 93 that passes through the pair of first clamping parts 91 and a first nut 94 embedded in one of the pair of first clamping parts 91. The amount of tightening of the second support column 30 by the pair of first clamping parts 91 can be changed by changing the amount the first bolt 93 is screwed into the first nut 94. By loosening the tightening of the second support column 30 by the pair of first clamping portions 91, the bracket 90f becomes slidable in the longitudinal direction of the second support column 30 and rotatable about the second support column 30. Therefore, the bracket 90f is configured to allow changes in its mounting position relative to the second support column 30.

[0060] The bracket 90f can be removed from the second support column 30 by moving the bracket 90f upward relative to the second support column 30 until the upper end of the second support column 30 comes out of the first retaining hole 91a. On the other hand, the bracket 90f can be attached to the second support column 30 by inserting the upper end of the second support column 30 into the first retaining hole 91a. Therefore, the bracket 90f is configured to be detachably attached to the second support column 30 via the upper end of the second support column 30.

[0061] The bracket 90f has a pair of second clamping parts 95 that clamp the support rod 80f, and a second tightening part 96 that tightens the pair of second clamping parts 95. The pair of second clamping parts 95 form a circular second holding hole 95a that holds the support rod 80f, and a second slit 95b connected to the second holding hole 95a. The central axis of the second holding hole 95a extends parallel to the central axis of the first holding hole 91a. The second tightening part 96 includes a second bolt 97 that passes through the pair of second clamping parts 95, and a second nut 98 embedded in one of the pair of second clamping parts 95. The amount of tightening of the support rod 80f by the pair of second clamping parts 95 can be changed by changing the amount the second bolt 97 is screwed into the second nut 98. By loosening the tightening of the support rod 80f in the pair of second clamping portions 95, the support rod 80f becomes slidable and rotatable relative to the bracket 90f in the longitudinal direction of the support rod 80f. Therefore, the bracket 90f is configured to change the holding position of the support rod 80f.

[0062] Brackets 90a to 90e, like bracket 90f, have a pair of first clamping portions 91, a first fastening portion 92, a pair of second clamping portions 95, and a second fastening portion 96. Therefore, brackets 90a to 90e, like bracket 90f, are configured to be detachably attached via the upper end of the first support column 20 or the upper end of the second support column 30. In brackets 90a to 90d, the central axis of the first holding hole 91a and the central axis of the second holding hole 95a are perpendicular to each other. The second clamping portions 95 of brackets 90a to 90d hold the horizontally extending portions of support rods 80a to 80d. The second clamping portions 95 of brackets 90e and 90f hold the vertically extending portions of support rods 80e and 80f.

[0063] As shown in Figures 8 and 10, the first support portion 22 has a mounting portion 23 configured to attach the sound source device 16. The mounting portion 23 has a pair of grooves 24 that open opposite each other in the direction in which the pair of second support columns 30 are aligned and extend in the vertical direction. The upper end of each groove 24 opens upward, while the lower end is closed.

[0064] As shown in Figure 10, the sound source device 16 has a vertically elongated rectangular parallelepiped housing. On the lower back surface of the housing, there is a plate-shaped sliding part 16a that is configured to be inserted into a pair of grooves 24 from above. The sound source device 16 is attached to the mounting part 23 by inserting the sliding part 16a into the pair of grooves 24.

[0065] On the underside of the upper part of the housing, there is a support projection 16b that contacts the first support column 20 to maintain the posture of the sound source device 16. <Operation of this embodiment> As shown in Figures 2 to 5, when the pair of second support columns 30 are unfolded and folded relative to the first support column 20, each first arm 40 and each second arm 50 rotates relative to the first support column 20 and the second support column 30 around the axis extending horizontally. Therefore, it is possible to suppress changes in the opening angle of the pair of first arms 40 and the pair of second arms 50 as viewed from above and below before and after the unfolding of the pair of second support columns 30. This suppresses variations in the position of the pair of second support columns 30 relative to the first support column 20 after the unfolding of the pair of second support columns 30. As a result, even when the unfolding of the pair of second support columns 30 is repeated, the shape and size of the triangle formed by the line segment L connecting the central axis of the first support column 20 and the central axis of each second support column 30 is less likely to change as viewed from above and below.

[0066] Furthermore, according to the above configuration, the pair of second support columns 30 are folded relative to the first support column 20 by the rotation of the pair of first arms 40 and the pair of second arms 50. Since each second support column 30 is rotatably supported relative to the first arms 40 and the second arms 50, the stand 11 can be folded in a position where the pair of second support columns 30 are aligned with the first support column 20.

[0067] <Effects of this embodiment> (1) The first support column 20 and the pair of second support columns 30 are arranged such that, when viewed from above, the line segment L connecting the central axis of the first support column 20 and the central axes of each of the pair of second support columns 30 forms a triangle. Each first arm 40 is rotatably supported relative to the first support column 20 and the second support column 30 about an axis extending horizontally. The pair of second support columns 30 are configured to be unfolded and folded relative to the first support column 20 by the rotation of the pair of first arms 40.

[0068] According to the above configuration, it is possible to achieve both improved reproducibility of the shape of the stand 11 in the unfolded state and suppression of an increase in the size of the stand 11 in the folded state. (2) Each second arm 50 is rotatably supported with respect to the first column 20 and the second column 30 about an axis extending in the horizontal direction.

[0069] According to the above configuration, each second support column 30 is connected to the first support column 20 by the first arm 40 and the second arm 50. This makes it easier to stabilize the posture of the pair of second support columns 30. Therefore, the reproducibility of the shape of the stand 11 in the deployed state can be improved.

[0070] (3) The first support column 20 and the pair of second support columns 30 extend parallel to each other. The pair of first arms 40 and the pair of second arms 50 extend parallel to each other. According to the above configuration, the pair of first arms 40 and the pair of second arms 50 rotate relative to the first support column 20, so that the pair of second support columns 30 are deployed and folded while maintaining a position parallel to the first support column 20. Therefore, the reproducibility of the shape of the stand 11 in the deployed state can be improved.

[0071] (4) The pair of second support columns 30 are configured to unfold and fold relative to the first support column 20 in conjunction with the sliding of the slider 60. According to the above configuration, by sliding the slider 60 in the longitudinal direction of the first support column 20, the pair of second support columns 30 are simultaneously extended and retracted relative to the first support column 20. Therefore, the extension and retraction of the pair of second support columns 30 can be easily performed.

[0072] (5) The pair of first arms 40 connect the first support column 20 and the pair of second support columns 30 at a position above the pair of second arms 50. The pair of stays 61 connect the slider 60 and the pair of first arms 40.

[0073] According to the above configuration, the first arms 40, which are connected to the first and second support columns 20 and 30 at a position above each second arm 50, are supported by the stays 61. Therefore, compared to the case where each stay 61 is connected to the second arm 50, each stay 61 can receive the load of the pads supported by each second support column 30 at a higher position. Thus, the stability of the stand 11 is improved.

[0074] (6) The first support 20 is positioned further back than the pair of second support 30, as viewed from the performer. With the above configuration, as shown in Figure 1, a space is formed at the feet of the performer, enclosed by the first support column 20 and a pair of second support columns 30. Therefore, this space can be used as a space for placing the bass drum pad 12.

[0075] (7) The vertical length of each second support column 30 is shorter than the vertical length of the first support column 20. With the above configuration, when a performer plays the first tom pad 14b and the second tom pad 14c, which are supported by the first support 20, the second support 30 is prevented from interfering with the performance.

[0076] (8) The stand 11 is equipped with a mounting member 70 to which the bass drum pad 12 is attached. With the above configuration, the bass drum pad 12 is attached to the mounting member 70, which restricts the bass drum pad 12 from moving closer to the first support column 20 due to the impact of striking the bass drum pad 12. This suppresses changes in the relative position of the bass drum pad 12 and other pads. In addition, it eliminates the need to provide a separate structure for fixing the bass drum pad 12 to the mounting surface FL.

[0077] (9) Brackets 90a to 90f are configured to be detachable via the upper end of the first support column 20 or the second support column 30. For example, when attaching brackets 90a to 90f to the first arm 40, the end of the first arm 40 is connected to the first support column 20 or the second support column 30, making it difficult to attach and detach the brackets 90a to 90f via the end of the first arm 40.

[0078] In this regard, with the above configuration, brackets 90a to 90f can be attached and detached via the upper end of the first support column 20 or the upper end of the second support column 30. Therefore, brackets 90a to 90f can be easily attached and detached. Consequently, the pads can be easily attached and detached from the stand 11.

[0079] (10) The first support portion 22 has a mounting portion 23 that is configured to allow the sound source device 16 to be attached. According to the above configuration, it is not necessary to prepare a separate part for attaching the sound source device 16 to the stand 11, in addition to the first support part 22. Therefore, it is possible to suppress an increase in the number of parts that make up the stand 11.

[0080] <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.

[0081] The first support portion 22 does not necessarily have to have a mounting portion 23. In this case, the stand 11 may have a connecting member that connects the first support column 20 and the sound source device 16, in addition to the first support portion 22.

[0082] Brackets 90a to 90f may be fixed to the first support column 20 or the second support column 30 in a way that prevents them from being detached. Each pad may be directly fixed to the first support column 20 or the second support column 30.

[0083] The stand 11 does not necessarily have to be equipped with a mounting member 70. In this case, the stand 11 and the bass drum pad 12 may be installed on the mounting surface FL at a distance from each other. The vertical length of each second support column 30 may be greater than or equal to the vertical length of the first support column 20.

[0084] The first support 20 may be positioned in front of the pair of second supports 30, as viewed from the performer. The pair of stays 61 may connect the slider 60 and the pair of second arms 50, respectively. In this case, each stay 61 is rotatably supported with respect to the slider 60 and the second arms 50 about a horizontally extending axis.

[0085] The stand 11 may include a pair of sliders 60, each individually supporting a pair of stays 61. The stand 11 does not necessarily have to be equipped with a slider 60 and a pair of stays 61. In this case, it is preferable for the performer to individually extend and fold the pair of second support columns 30 relative to the first support column 20.

[0086] The stand 11 does not necessarily have to include a slider 60, a pair of stays 61, and a pair of second arms 50. That is, each second support column 30 may be connected to the first support column 20 only by the first arm 40. In this case, it is preferable for the performer to adjust the parallelism of each second support column 30 to the first support column 20 when extending and folding the pair of second arms 50.

[0087] Each second support column 30 does not have to extend strictly parallel to the first support column 20, and may extend at a slight incline. The vertical lengths of the pair of second support columns 30 may be different from each other.

[0088] The first support column 20 and each of the second support columns 30 may be configured to extend and retract in the vertical direction. The first support column 20 and each of the second support columns 30 may, for example, be equipped with a telescopic mechanism in which multiple pipes of different diameters are arranged to slide coaxially.

[0089] The lengths of the pair of first arms 40 may be different from each other. The lengths of the pair of second arms 50 may be different from each other. The lengths of the pair of stays 61 may be different from each other. In this case, the triangle formed by the line segment L connecting the central axis of the first support column 20 and the central axes of each second support column 30 does not have to be an isosceles triangle.

[0090] The stand 11 may include three or more second support columns 30 that are configured to be unfoldable and foldable relative to the first support column 20. The stand 11 may include a third support column that is configured to be unfoldable and foldable relative to at least one of the pair of second support columns 30.

[0091] Stand 11 can also be used as a stand to support acoustic drums or practice pads that do not have vibration sensors. Furthermore, Stand 11 can also be used as a stand to support percussion instruments other than drums. [Explanation of Symbols]
