Description

Technical Field

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

[0002] Drum practice kits are known to allow for drum practice in one's own room. For example, a drum practice kit disclosed in U.S. Patent No. 7,348,479 includes: a cylindrical stand with a tripod and tubing; and various practice pads. Disc-shaped practice pads of different diameters are mounted on the upper part of the stand via rods and positioning components. These practice pads include snare drum pads, tom-tom pads, cymbal pads, etc.

[0003] At the center of the stand, a roughly elliptical bass drum practice pad is mounted via a positioning component. At the lower end of the stand is a connecting mechanism for connecting the drum practice kit to the pedal assembly. The connecting mechanism includes a shaft and a plate extending horizontally from the lower end of the shaft. The shaft is inserted into a tube within the stand and secured within the tube by screws.

[0004] The pedal assembly includes: a pedal base; a pedal connected to the pedal base; and drumsticks connected to the free end of the pedal via a chain. A clamp for connection with a drum practice kit is located at the center of the front end of the pedal base. The drum practice kit is fixed to the clamp via a connecting mechanism plate and thus connected to the pedal assembly. In this state, the drum practice kit is placed on the floor and used with the pedal assembly.

[0005] Regarding pedal mechanisms, multiple manufacturers offer various pedal mechanisms, and even the same manufacturer may offer a variety of pedal mechanisms. Furthermore, pedal mechanisms utilize various clamps with different heights and angles depending on their type. Therefore, drum practice kits must be able to connect to various pedal mechanisms according to the height and angle of the clamps.

[0006] Regarding this point, according to the drum practice kit disclosed in U.S. Patent No. 7,348,479, when the screw is loosened, the shaft can move vertically within the tube, allowing adjustment of the plate's vertical position. This allows the drum practice kit to be connected to the pedal assembly according to the height of the clamp. However, this connection mechanism is not configured to connect the drum practice kit to the pedal assembly according to the angle of the clamp. Therefore, when the clamp is at an angle, the legs of the support and the bottom surface of the pedal base are not aligned on the same plane when the pedal assembly is connected to the drum practice kit. Consequently, the posture of the drum practice kit on the mounting surface becomes unstable, sometimes hindering drum practice.

[0007] Therefore, the proposal is like Figure 18The bass drum practice pad 200 shown is described. The bass drum practice pad 200 includes: a pad base 201; a plurality of main posts 202 fixed to the upper surface of the pad base 201; and a pad body 203 fixed to the upper ends of the plurality of main posts 202. A connecting member 204 for connecting the bass drum practice pad 200 to the pedal device 300 is fitted to the pad base 201.

[0008] like Figure 19 As shown, the connecting member 204 includes: two fixing portions 204a, which are fixed to both sides of the pad base 201 by screws 205; and an extension portion 204b, which extends between the two fixing portions 204a. The bass drum practice pad 200 is fixed to the clamp 301 by the extension portion 204b of the connecting member 204 and is connected to the pedal device 300. In this state, the bass drum practice pad 200 is placed on the clamp 301. Figure 18 It is placed on the surface FL shown and used with the pedal device 300.

[0009] A through hole 204c for inserting a screw 205 is formed in the fixing portion 204a of the connecting member 204. The through hole 204c is longitudinally elongated. In addition, screw holes (not shown) for inserting screws 205 are formed on both sides of the pad base 201. According to this structure, when the screw 205 is loosened, the connecting member 204 can move in the vertical direction relative to the pad base 201 and can rotate about the axis of the screw 205. Thus, not only the height of the clamp 301, but also the angle of the clamp 301 can be adjusted to connect the bass drum practice pad 200 to the pedal device 300.

[0010] However, in Figure 18 and Figure 19 In the case of the bass drum practice pad 200 shown, when the pedal is pressed, the drumstick strikes the pad body 203, thereby creating a torque between the connecting member 204 located at the lower part of the bass drum practice pad 200 and the pad body 203 located at the upper part of the bass drum practice pad 200. At this time, because the distance between the connecting member 204 and the pad body 203 is large, the vicinity of the connecting member 204 is easily affected by the torque. In addition, since the connecting member 204 is connected to the pad base 201 by screws 205, the torque-based force acting on the connecting member 204 causes the connection angle between the connecting member 204 and the pad base 201 to deviate from the adjusted angle, and the positions of the support 202 and the pad body 203 sometimes deviate from the adjusted positions. Therefore, when the pedal is repeatedly pressed, an intermittent torque-based force is applied to the connecting member 204, thereby increasing the deviation of the connection angle between the connecting member 204 and the pad base 201, and potentially increasing the positional deviation of the support 202 and the pad body 203. As mentioned above, in the bass drum practice pad 200, the posture of the bass drum practice pad 200 on the mounting surface is unstable, which sometimes hinders drum practice. Summary of the Invention

[0011] The purpose of this invention is to provide a bass drum pad and drum kit with improved stability when mounted in connection with a pedal device.

[0012] To achieve the above-mentioned objectives, according to a first aspect of the present invention, a bass drum pad is provided for use in connection with a clamp of a pedal device. The bass drum pad includes: a pad base fixed to the clamp; a main post integrally formed with the pad base; a pad body disposed on the main post and struck by the pedal device; and legs disposed on the main post or the pad body for use when mounting the bass drum pad.

[0033] The following is for reference Figures 1 to 14 An embodiment of the present invention, which specifically embodies the bass drum pad and the drum kit, as a bass drum practice pad (hereinafter referred to as a bass pad) and a drum practice kit, will be described.

[0034] Figure 1 As shown, the drum practice kit 1 includes a bass pad 10, a tom-tom pad 11, a snare drum pad 12, a cymbal pad 13, and a hi-hat pad 14. The tom-tom pad 11 and the snare drum pad 12 are used when attached to the tom-tom stand 11S and the snare drum stand 12S, respectively. The cymbal pad 13 is used when attached to the cymbal stand 13S. The hi-hat pad 14 is used when attached to the hi-hat stand 14S, which is equipped with a pedal mechanism. The bass pad 10 is used when connected to the pedal mechanism PD.

[0035] like Figures 2 to 4As shown, the bass pad 10 includes a frame body 20, a pad body 30, and a leg opening mechanism 40. The bass pad 10 is constructed by assembling the pad body 30 and the leg opening mechanism 40 into the frame body 20.

[0036] The frame body 20 has a base 21 and a main column 22 integrally formed on the base 21. The frame body 20 is made of a steel plate stamped into a predetermined shape, formed by pressure forming after lightweight processing of the steel plate. The base 21 is part of the frame body 20 and is fixed to... Figure 1 The clamping portion of the pedal device PD shown is shown. The pad base 21 is a rectangular plate with two side edges extending in the length direction. Near the first side edge 21a of the pad base 21, a rib 21c extending along the first side edge 21a is formed.

[0037] The main column 22 is part of the frame body 20, extending from the second side edge 21b of the base 21 in a direction perpendicular to the surface of the base 21. The lower half of the main column 22 has a lower back portion 22a extending from the second side edge 21b of the base 21, and two lower side edge portions 22b provided on both sides of the lower back portion 22a. A lower opening 22c is formed in the center of the lower back portion 22a. The lower opening 22c is generally rectangular in shape and extends along the length of the main column 22. The lower side edge portions 22b are L-shaped sections forming both sides of the lower half of the main column 22.

[0038] The upper half of the main column 22 has an upper back portion 22d extending continuously from the lower back portion 22a, and two upper side edge portions 22e provided on both sides of the upper back portion 22d. An upper opening 22f is formed in the center of the upper back portion 22d. The upper opening 22f is approximately rectangular in shape and extends along the length of the main column 22. The length of the upper opening 22f is smaller than the length of the lower opening 22c. In addition, upper holes 23 and lower holes 24 are formed at the four corners of the upper back portion 22d, respectively. Bolts 25 for mounting the pad body 30 on the main column 22 are inserted into the upper holes 23 and lower holes 24. The upper side edge portions 22e are flat plate-shaped parts that constitute the two sides of the upper half of the main column 22.

[0039] like Figure 5 and Figure 6 As shown, the pad body 30 includes an impact surface component 31, an inner side plate 29, a pad cover 32, damping materials 33a, 33b, and 33c, and a main body component 34. The pad body 30 is constructed by assembling the impact surface component 31, the inner side plate 29, the pad cover 32, the damping materials 33a, 33b, and 33c, and the main body component 34, which are arranged coaxially, into a single unit.

[0040] The striking surface component 31 is constructed from a circular sheet of material. For the striking surface component 31, cloth is used as the material to approximate the sound and impact of a bass drum. The striking surface component 31 has a [missing information - likely referring to a specific feature or design]. Figure 1 The pedal device PD shown is struck on the striking surface 31a. Near the outer periphery of the striking surface component 31, four through holes 31c are formed at equal angular intervals. The inner side plate 29 is made of a circular rubber sheet. Near the outer periphery of the inner side plate 29, four through holes 29c are formed at equal angular intervals.

[0041] The pad cover 32 is made of annular plate. Four through holes 32c are formed in the pad cover 32 at equal angles. Screws 35 are inserted into the through holes 29c of the inner side plate 29, the through holes 31c of the striking surface component 31, and the through holes 32c of the pad cover 32, respectively, for fixing the striking surface component 31 and the inner side plate 29 to the main body component 34 together with the pad cover 32.

[0042] The main body component 34 is a bottomed cylindrical shape. The main body component 34 consists of a circular base plate portion 34a and a cylindrical portion 34b located on the outer periphery of the base plate portion 34a. Four screw holes 34c are formed at equal angular intervals in the cylindrical portion 34b. Screws 35 are inserted into the screw holes 34c to pass through the insertion holes 29c of the inner side plate 29, the insertion hole 31c of the striking surface component 31, and the insertion hole 32c of the pad cover 32. A circular recess 39 is formed in the main body component 34 by the inner peripheral surfaces of the base plate portion 34a and the cylindrical portion 34b.

[0043] The damping materials 33a, 33b, and 33c are composed of circular plate-shaped sponges. For damping materials 33a and 33b, which are located near the inner side plate 29, a softer sponge is used. Conversely, for damping material 33c located near the main body component 34, a harder sponge is used. The damping materials 33a, 33b, and 33c are disposed within the space of the pad body 30 to absorb the impact when the surface component 31 is struck by the pedal device PD.

[0044] Ten air holes 36 are formed in the base plate 34a. The ten air holes 36 are arranged at intervals on the entire base plate 34a in a symmetrical position with respect to the center of the base plate 34a. The number and size of the air holes 36 are set according to the results of the prototype and experiment, so that the sound and feel when the pad body 30 is struck are close to the sound and impact of a bass drum.

[0045] like Figure 6As shown, the recess 39 of the pad body 30 only accommodates the damping material 33c. The damping materials 33a and 33b are disposed on the surface of the damping material 33c, on the outer side of the recess 39 of the pad body 30. The impact surface component 31 and the inner side plate 29 are assembled to the main body component 34, covering the entire surface of the damping material 33a and pressing the damping materials 33a and 33b against the impact surface 31a. The impact surface component 31 and the inner side plate 29 are fixed to the main body component 34 together with the pad cover 32 by screws 35.

[0046] In the pad body 30, the portion including the striking surface component 31, the inner side plate 29, and the damping materials 33a and 33b is convex, so that the feeling when striking the striking surface component 31 is similar to the impact of a bass drum. Furthermore, the inner side plate 29 seals the space within the pad body 30 so that air within the pad body 30 does not escape from the striking surface component 31 when it is struck. That is, the pad body 30 is configured such that when striking the striking surface component 31, air within the pad body 30 only escapes through the air hole 36.

[0047] like Figures 3 to 5 As shown, four fixing parts 34d protrude from the back of the main body component 34 and are fixed to the main column 22. Each fixing part 34d has a screw hole for inserting a bolt 25. The pad body 30 is assembled to the main column 22 by being fixed to the upper hole 23 via the four fixing parts 34d. Figure 3 The first position is shown by the solid line. The pad body 30 is fixed to the lower hole 24 of the main column 22 by four fixing parts 34d and assembled to the... Figure 3 The second position is indicated by the double-dotted line. The first position is parallel to the second position along the axial direction of the main column 22, and is positioned above the second position. The assembly position of the pad body 30 assembled on the main column 22 can be changed along the axial direction of the main column 22.

[0048] like Figures 2 to 4 As shown, the leg-opening mechanism 40 includes two legs 41, two support bars 42, and a sliding member 43. Each leg 41 includes a leg plate 41a connected to the main column 22, and a rubber stop 41b fitted to the front end of the leg plate 41a. The length of the leg plate 41a is greater than the length of the main column 22. The base of the leg plate 41a is rotatably connected to the upper ends of both sides of the main column 22 using screws 44. The two legs 41 are configured to be symmetrically connected to the main column 22, such that the distance between the two legs 41 increases towards the lower end of the main column 22. The stop 41b contacts the mounting surface of the bass pad 10, making it difficult for the bass pad 10 to slide on the mounting surface.

[0049] The two support bars 42 are components used to connect the two legs 41 to the sliding member 43. The support bars 42 are rotatably connected to the central part of the leg 41 and the sliding member 43 using rivets 45 and screws 46, respectively.

[0050] The sliding member 43 is composed of a surface member 47 and a back member 48. Through holes 47a and 48a are formed at the center of each of the surface member 47 and the back member 48. Bolts 50 for assembling the surface member 47 and the back member 48 and for assembling the sliding member 43 to the main post 22 are inserted into the two through holes 47a and 48a. The surface member 47 and the back member 48 are assembled to the main post 22 in a manner that clamps the main post 22 from the surface side and the back side, thereby constituting the sliding member 43.

[0051] A coil spring 51 is embedded in the shaft portion of the bolt 50, which is disposed within the sliding member 43. Additionally, a wing nut 52 is tightened onto the front end of the bolt 50, which is disposed outside the sliding member 43. When the bolt 50 is tightened with the wing nut 52, the sliding member 43 is fixed to the main post 22 by the force of the surface member 47 and the back member 48 clamping the main post 22. When the wing nut 52 is loosened, the force of the surface member 47 and the back member 48 clamping the main post 22 weakens, thus allowing the sliding member 43 to slide relative to the main post 22.

[0052] like Figure 2 , Figure 3 , Figure 7 as well as Figure 8 As shown, the sliding component 43 is in Figure 2 and Figure 3 The upper limit position shown is the same as Figure 7 and Figure 8 Between the lower limit positions shown, it is possible to slide in the axial direction of the main column 22. By sliding the sliding member 43 in the axial direction of the main column 22, the leg 41 and the support bar 42 rotate about the screws 44 and 46 respectively, opening and closing relative to the main column 22.

[0053] When in the configuration of using the bass pad 10, the sliding member 43 is positioned at the upper limit of the main column 22, thereby fully opening the legs 41 and the support bar 42 relative to the main column 22. Furthermore, by tightening the wing nut 52 with the bolt 50, the sliding member 43 is fixed at the upper limit of the main column 22, thereby maintaining the legs 41 and the support bar 42 in an open state relative to the main column 22.

[0054] When configured to house the bass pad 10, the sliding member 43 is positioned at the lower limit on the main column 22, thereby closing the legs 41 and the support bar 42 relative to the main column 22. Furthermore, by tightening the wing nut 52 with the bolt 50, the sliding member 43 is fixed at the lower limit on the main column 22, thus maintaining the legs 41 and the support bar 42 in a closed state relative to the main column 22. In this state, the legs 41 are arranged parallel to the main column 22. The support bar 42 is arranged substantially parallel to the main column 22. That is, when viewed along the axial direction of the screws 44 and 46, the legs 41 and the support bar 42 are positioned overlapping the main column 22.

[0055] Next, refer to Figures 9 to 11 The positioning structure of the bass pad 10 and the tom-tom stand 11S is explained.

[0056] like Figure 9 and Figure 10 As shown, the tom-tom support 11S is configured such that, in the tom-tom support 11S and Figure 1 A bass pad 10 is disposed between the pedal devices PD shown. A positioning member 60 is used in the setup to position the tom-tom stand 11S relative to the bass pad 10. The positioning member 60 consists of a positioning body 61 and a buffer member 62.

[0057] like Figure 11 As shown, the positioning body 61 has a first positioning portion 63 and a second positioning portion 64 integrally formed with the top of the first positioning portion 63. The cross-section of the first positioning portion 63 is approximately triangular. The second positioning portion 64 is approximately cylindrical. The positioning body 61 is made of resin.

[0058] The first positioning part 63 has a fitting protrusion 63a serving as a first fitting part and two flat parts 63b provided on both sides of the fitting protrusion 63a. The fitting protrusion 63a has a rectangular cross-section. The fitting protrusion 63a, together with the buffer member 62, is inserted into the lower opening 22c of the main post 22. The flat parts 63b are arranged opposite to the lower back surface part 22a of the main post 22 when the buffer member 62 is installed between the flat parts 63b and the main post 22.

[0059] The buffer member 62 is a rectangular plate with a roughly U-shaped cross-section. The cross-sectional shape of the buffer member 62 is the same as that of the portion of the first positioning part 63 that includes the fitting protrusion 63a and the planar surface 63b. The buffer member 62 is used to insert between the positioning body 61 and the bass pad 10. When the bass pad 10 is played, the buffer member 62 absorbs the impact and vibration generated when the striking surface member 31 is struck. The buffer member 62 is made of a material with excellent impact and vibration absorption properties, specifically rubber, polyurethane, felt, etc.

[0060] A fitting recess 65, serving as a second fitting portion, is formed in the second positioning portion 64. The fitting recess 65 has an inner peripheral surface 65a extending along an arc. The second positioning portion 64 has two wall portions 66 formed by the outer surface 64a of the second positioning portion 64 and the inner peripheral surface 65a of the fitting recess 65. A protrusion 66a extending radially outward from the front end of each of the two wall portions 66 is provided. The second positioning portion 64 is configured to engage with the tube of the tom-shaped support 11S by bending both wall portions 66 as a whole. That is, the second positioning portion 64 is configured to allow the tube to be inserted into the fitting recess 65 and to retain the tube in the fitting recess 65.

[0061] Reference Figures 12 to 14 The function of the bass pad 10 described above will be explained.

[0062] Figures 12 to 14 The diagram shows the states where the first pedal assembly PD1, the second pedal assembly PD2, and the third pedal assembly PD3 are connected to the bass pad 10. For example... Figure 12 and Figure 13 As shown, the height of the clamp CL2 of the second pedal device PD2 is higher than the height of the clamp CL1 of the first pedal device PD1. Additionally, as... Figure 12 and Figure 14 As shown, the clamp CL1 is parallel to the bottom surface of the substrate BP of the first pedal device PD1, while the clamp CL3 of the third pedal device PD3 is inclined relative to the bottom surface of the substrate BP.

[0063] like Figures 12 to 14 As shown, the bass pad 10 is configured to allow adjustment of the height and angle of the pad base 21 based on the opening of the leg 41 relative to the main post 22. Here, the height of the pad base 21 is the position of the main post 22 along a vertical line H perpendicular to the mounting surface FL on which the bass pad 10 is placed. The angle of the pad base 21 is the angle of the axis L1 of the main post 22 relative to the vertical line H perpendicular to the mounting surface FL. Furthermore, the bass pad 10 is configured to allow adjustment of the height and angle of the pad base 21 while it is separated from the mounting surface FL. Additionally, the bass pad 10 is configured to allow adjustment of the front end position of the leg 41 while connected to the clamp of the pedal device PD.

[0064] First, refer to Figure 12 and Figure 13 This describes a series of operations performed when the bass pad 10 is connected to the pedal assembly, corresponding to the height of the clamp on the pedal assembly.

[0065] like Figure 12 and Figure 13 As shown, when the subwoofer pad 10 is removed from the first pedal assembly PD1 and connected to the second pedal assembly PD2, firstly, the base 21 of the subwoofer pad 10 is fixed in the clamp CL2 of the second pedal assembly PD2. Thus, the subwoofer pad 10 is connected to the second pedal assembly PD2 according to the height of the clamp CL2. Here, the clamp CL2 is parallel to the bottom surface of the substrate BP of the second pedal assembly PD2, i.e., the mounting surface FL. Therefore, if the base 21 is fixed in the clamp CL2, the main post 22 is positioned on the mounting surface FL with its axis L1 parallel to the vertical line H. Thus, the posture of the subwoofer pad 10 on the mounting surface FL is determined such that the main post 22 is positioned perpendicular to the mounting surface FL.

[0066] Next, the position of the front end of leg 41 is adjusted to stabilize the posture of the bass pad 10 on the mounting surface FL. At this time, with the wing nut 52 loosened, the opening of leg 41 and support bar 42 relative to the main post 22 is adjusted while sliding member 43 along the axis L1 of the main post 22. Furthermore, when the front end of leg 41 is on the same plane as the bottom surface of substrate BP, the wing nut 52 is tightened with bolt 50 to fix sliding member 43 to the main post 22. Thus, the open state of leg 41 and support bar 42 relative to the main post 22 is maintained, and the height of pad base 21 is fixed. In this state, since the bass pad 10 is supported by leg 41 and pedal device PD, the posture of bass pad 10 on the mounting surface FL is stabilized. The above series of operations are performed with pad base 21 separated from the mounting surface FL.

[0067] Next, refer to Figure 12 and Figure 14 This describes a series of operations corresponding to the angle of the clamp on the pedal assembly when the pedal assembly is connected to the bass pad 10.

[0068] like Figure 12 and Figure 14 As shown, when connecting the bass pad 10 to the third pedal assembly PD3 after it has been removed from the first pedal assembly PD1, the base 21 of the bass pad 10 is first fixed to the clamp CL3 of the third pedal assembly PD3. Thus, the bass pad 10 is connected to the third pedal assembly PD3 according to the angle of the clamp CL3. Here, the clamp CL3 is inclined relative to the bottom surface of the substrate BP of the third pedal assembly PD3, i.e., the mounting surface FL. Therefore, if the base 21 is fixed to the clamp CL3, the main post 22 is positioned on the mounting surface FL with its axis L1 inclined relative to the vertical line H. Thus, the posture of the bass pad 10 on the mounting surface FL is determined such that the main post 22 is positioned inclined relative to the vertical line H.

[0069] Next, the position of the front end of leg 41 is adjusted to stabilize the posture of the bass pad 10 on the mounting surface FL. At this time, with the wing nut 52 loosened, the opening of leg 41 and support bar 42 relative to the main post 22 is adjusted while sliding member 43 along the axis L1 of the main post 22. Then, with the front end of leg 41 on the same plane as the bottom surface of substrate BP, the wing nut 52 is tightened with bolt 50 to fix sliding member 43 to the main post 22. Thus, the open state of leg 41 and support bar 42 relative to the main post 22 is maintained, and the height of pad base 21 is fixed. Furthermore, in this state, since the bass pad 10 is supported by leg 41 and pedal device PD, the posture of bass pad 10 on the mounting surface FL can be stabilized. The above series of operations are performed with pad base 21 separated from the mounting surface FL.

[0070] Therefore, according to this embodiment, the following effects can be obtained.

[0071] (1) The bass pad 10 is configured such that the height and angle of the pad base 21 can be adjusted. Here, the height of the pad base 21 is the position of the main post 22 along the vertical line H perpendicular to the mounting surface FL on which the bass pad 10 is mounted, corresponding to the clamp height of the pedal device PD. The angle of the pad base 21 is the angle of the axis L1 of the main post 22 relative to the vertical line H perpendicular to the mounting surface FL, corresponding to the angle of the clamp of the pedal device PD. Therefore, by making the height and angle of the pad base 21 adjustable, the bass pad 10 can be connected to various pedal devices PDs corresponding to both the height and angle of the clamp. In addition, the main post 22 is integrally provided with the pad base 21 fixed to the clamp. That is, there is no place in the bass pad 10 to adjust the connection angle between the part fixed to the clamp and the pad base 21. Therefore, even if the pedal is repeatedly pressed to intermittently apply a torque-based force to the part fixed to the clamp, the positions of the main post 22 and the pad body 30 will not deviate from the adjusted position. This improves the stability when the bass pad 10 is connected to the pedal device PD for mounting.

[0072] (2) The bass pad 10 is configured such that the height and angle of the pad base 21 can be adjusted when the pad base 21 is separated from the mounting surface FL. According to this structure, by separating the pad base 21 from the mounting surface FL, the pad base 21 and the mounting surface FL will not interfere with each other when adjusting the height and angle of the pad base 21. Therefore, the bass pad 10 can be easily connected to the pedal device PD according to both the height and angle of the clamp. Furthermore, it is also easy to stabilize the posture of the bass pad 10 on the mounting surface FL.

[0073] (3) The bass pad 10 is configured such that, when connected to the clamp of the pedal device PD, the position of the front end of the leg 41 can be adjusted. According to this configuration, when the bass pad 10 is connected to the clamp, the position of the front end of the leg 41 can be adjusted so that the front end of the leg 41 is placed on the mounting surface FL. Therefore, after the bass pad 10 is connected to the clamp, the front end of the leg 41 of the bass pad 10 and the bottom surface of the pedal device PD can be arranged on the same plane. Thus, since the bass pad 10 is supported by the leg 41 and the pedal device PD, the posture of the bass pad 10 on the mounting surface FL can be stabilized.

[0074] (4) The bass pad 10 is configured such that the height and angle of the pad base 21 can be adjusted according to the opening of the legs 41. This structure facilitates easy connection of the bass pad 10 to the pedal assembly PD, accommodating both the height and angle of the clamp. Furthermore, since the front end position of the legs 41 can be adjusted according to the opening of the legs 41, it is easy to align the front end of the legs 41 of the bass pad 10 and the bottom surface of the pedal assembly PD on the same plane. This also facilitates the stability of the bass pad 10's posture on the mounting surface FL.

[0075] (5) When the wing nut 52 is loosened, the sliding member 43 can slide along the axis of the main column 22. Furthermore, by sliding only the sliding member 43 relative to the main column 22, the legs 41 and the support bar 42 open and close relative to the main column 22, respectively, and the height and angle of the pad base 21 are adjusted. This makes it easier to connect the bass pad 10 to the pedal device PD and to stabilize the posture of the bass pad 10 on the mounting surface FL, both according to the height and angle of the clamp. Additionally, when the wing nut 52 is tightened with the bolt 50, the sliding member 43 is fixed to the main column 22. This maintains the open state of the legs 41 and the support bar 42 relative to the main column 22, and the height and angle of the pad base 21 are fixed. This further improves the stability when the bass pad 10 is connected to the pedal device PD and mounted.

[0076] Furthermore, the sliding member 43 is connected to the support bar 42, which is closably assembled to the main column 22. The sliding direction of the sliding member 43 relative to the main column 22 is along the axis of the main column 22, which differs significantly from the opening direction of the support bar 42 relative to the main column 22. Therefore, although the pedal application exerts a force on the leg 41 and support bar 42 in the opening direction relative to the main column 22, the significant difference between the sliding direction of the sliding member 43 and the opening direction of the leg 41 and support bar 42 prevents the leg 41 and support bar 42 from opening due to the pedal application.

[0077] (6) The sliding component 43 is capable of... Figure 2 and Figure 3 The upper limit position shown is the same as Figure 6 and Figure 7 The sliding member 43 slides along the axis of the main column 22 between the indicated lower limit positions. According to this structure, to position the bass pad 10 in use, the height and angle of the pad base 21 can be adjusted simply by moving the sliding member 43 between the upper and lower limit positions on the main column 22. To position the bass pad 10 in storage, the sliding member 43 can be moved to the lower limit position on the main column 22. Thus, the relationship between the position of the sliding member 43 on the main column 22 and the opening and closing of the legs 41 and support bars 42 becomes clear. Therefore, the ease of operation of the bass pad 10 is improved.

[0078] (7) When the bass pad 10 is in its stored position, the legs 41 and the support bar 42 can be arranged to be approximately parallel to the main column 22 by moving the sliding member 43 to the lower limit position on the main column 22. As a result, the bass pad 10 can be stored in a compact form.

[0079] (8) The leg-opening mechanism 40 has two legs 41 and two support bars 42. According to this structure, the stability of the bass pad 10 when it is mounted on the pedal device PD is further improved by the three-point support based on the two legs 41 and the pedal device PD.

[0080] (9) The mounting position of the pad body 30 assembled to the main column 22 can be changed in the axial direction of the main column 22. According to this structure, the straight-line distance from the mounting surface FL to the center of the pad body 30, i.e., the height of the pad body 30, can be changed. Thus, the height of the pad body 30 can be adjusted according to the type of pedal device PD to strike the center of the pad body 30.

[0081] (10) The tom-tom stand 11S is configured such that a bass pad 10 is disposed between the tom-tom stand 11S and the pedal device PD. A positioning member 60 is used to position the tom-tom stand 11S relative to the bass pad 10 during setup. At this time, by using the positioning member 60, positioning the tom-tom stand 11S relative to the bass pad 10 becomes easy, and the setup of the drum practice kit 1 becomes easy.

[0082] Furthermore, by positioning the tom-tom stand 11S relative to the bass pad 10, the bass pad 10 and the tom-tom stand 11S are difficult to move due to their combined weight during performance of the drum practice kit 1. Therefore, stability is improved when the bass pad 10 and the tom-tom stand 11S are in place. Additionally, since interference between the bass pad 10 and the tom-tom stand 11S is minimal during performance of the drum practice kit 1, noise and scratches caused by contact between the bass pad 10 and the tom-tom stand 11S can be prevented.

[0083] (11) The positioning body 61 has a first positioning portion 63 and a second positioning portion 64. A fitting protrusion 63a is formed in the first positioning portion 63. A fitting recess 65 is formed in the second positioning portion 64. According to this structure, the tom-tom stand 11S is positioned relative to the bass pad 10 simply by inserting the tube of the tom-tom stand 11S into the fitting recess 65 and inserting the fitting protrusion 63a into the lower opening 22c of the main post 22. That is, by using the positioning member 60, the positioning of the tom-tom stand 11S relative to the bass pad 10 becomes easier, and the setup of the drum practice kit 1 becomes easier.

[0084] (12) The positioning component 60 consists of a positioning body 61 and a buffer component 62. With the bass pad 10 and the tom-tom stand 11S positioned by the positioning component 60, the buffer component 62, together with the fitting protrusion 63a, is inserted into the lower opening 22c of the main post 22. Furthermore, the buffer component 62 is positioned between the flat portion 63b and the main post 22. According to this structure, the buffer component 62 can absorb the impact and vibration generated when the bass pad 10 is struck. Therefore, the noise generated during the playing of the drum practice kit 1 is suppressed, thus improving the quietness of the drum practice kit 1.

[0085] This implementation method can also be modified as described below.

[0086] Although the drum kit is embodied as a drum practice kit 1, it can also be embodied as an electronic drum kit. In addition, although the bass pad 10 is embodied as a bass drum practice pad, it can also be embodied as a bass pad 10 constituting an electronic drum kit.

[0087] Regarding the drum practice kit 1, although it is a percussion pad different from the bass pad 10, it includes a tom-tom pad 11, a snare drum pad 12, a cymbal pad 13, and a hi-hat pad 14, the necessary percussion pads can also be used to construct the drum practice kit 1.

[0088] Regarding the bass pad 10, although it is constructed by connecting the two legs 41 to the main post 22, it can also be configured as follows: Figure 15 As shown, the two legs 41 are connected to the main body 30 of the pad to form the structure.

[0089] Regarding the pad base 21 and the main column 22, although they are each constituted as a component of the frame body 20, they can also be separate components. In this case, fastening components such as screws can be used to assemble the pad base 21 and the main column 22 into a single unit to form the frame body 20.

[0090] Regarding the two support bars 42, although they are components used to connect the two legs 41 and the sliding component 43, they can also be used as... Figure 16 As shown, this is the component connecting the two legs 71 to the lower end of the main column 72. At this time, the two legs 71 are connected to the sliding member 73, and a support bar 74 is connected to the center of the two legs 71. Even with this structure, the legs 71 and the support bar 74 can be opened and closed relative to the main column 72 by sliding the sliding member 73 along the axial direction of the main column 72.

[0091] It can also replace Figure 10 The positioning component 60 shown uses Figure 17 Positioning component 80 is shown. (As shown) Figure 17As shown, instead of the first positioning part 63 of the positioning member 60, the positioning member 80 includes a fixing part 81 that is fixed to the main post 22 of the bass pad 10. Furthermore, instead of the second positioning part 64 of the positioning member 60, the positioning member 80 includes a clamping part 82 that fixes the tube of the tom-tom bracket 11S. The positioning member 80 is assembled to the bass pad 10 by fixing the fixing part 81 to the main post 22 using two screws 83. Regarding the positioning member 80, the tube of the tom-tom bracket 11S is also assembled to the tom-tom bracket 11S by fixing it to the clamping part 82 using bolts 84 and wing nuts 85. As described above, by using the positioning member 80, not only is the positioning of the tom-tom bracket 11S relative to the bass pad 10 achieved, but also positional displacement of the tom-tom bracket 11S relative to the bass pad 10 can be prevented. Furthermore, according to this structure, the positioning of the tom-tom bracket 11S relative to the bass pad 10 can be performed regardless of the presence or absence of the legs of the tom-tom bracket 11S.

[0092] Regarding the positioning components 60 and 80, in addition to being used for positioning the tom-tom stand 11S relative to the bass pad 10, they can also be used for positioning the snare drum stand 12S, cymbal stand 13S, and hi-hat stand 14S relative to the bass pad 10.

[0093] Regarding the positioning component 60, although it consists of a positioning body 61 and a buffer component 62, the buffer component 62 can be omitted, and it can consist only of the positioning body 61.

[0094] Regarding the assembly position of the pad body 30 assembled to the main column 22, although it can be changed to position 1 and position 2 in stages, it can also be changed arbitrarily. For example, instead of the upper hole 23 and lower hole 24 formed on the main column 22, as long as an elongated hole extending in the axial direction of the main column 22 is formed, the assembly position of the pad body 30 can be changed arbitrarily along the axial direction of the main column 22 along the elongated hole.

[0095] Although the position of the front end of the leg 41 can be adjusted based on the opening of the leg 41 relative to the main post 22, it can also be adjusted by configuring the leg 41 to slide relative to the main post 22 and by allowing the leg 41 to slide along the axis of the main post 22. Alternatively, the position of the front end of the leg 41 can be adjusted by configuring the leg 41 to be retractable and by changing the length of the leg 41.
