[0015] The following is for reference Figures 1-8 An embodiment applying this disclosure to a keyboard musical instrument assembly will be described. For example... Figures 1-4 As shown, the keyboard instrument assembly 100 includes a keyboard instrument 1 and a stand 2. The keyboard instrument 1 has an instrument shell 3 that extends horizontally in the left-right direction. The instrument shell 3 is provided with a keyboard section 4 in which a plurality of white keys and a plurality of black keys are arranged along the long side in the left-right direction.

[0016] In this disclosure, the left-right direction refers to the left-right direction as viewed from the position where the player of the keyboard instrument 1 is standing while playing. Furthermore, the up-down direction defines the surface of the keyboard instrument 1 where the keyboard section 4 is located as the upper surface, and the surface opposite it as the lower surface. Moreover, the front-back direction means the direction with the player's side in front and the opposite side behind.

[0017] like Figures 1-5 As shown, the support 2 includes: a cylindrical horizontal frame 5 that extends horizontally in the left-right direction (i.e., laterally) where the keyboard instrument 1 is mounted; two connecting members 6 that are located at the two ends of the horizontal frame 5 in the left-right direction (i.e., laterally); two legs 7 that are respectively mounted on the connecting members 6 and support the front of the keyboard instrument 1; a pedal frame 8 that is mounted on the connecting members 6 on both sides and supports the rear of the keyboard instrument 1; and a pedal device 9 that is fixed to the pedal frame 8.

[0018] like Figures 5-8 As shown, the two connecting structural members 6 each include: a crossbeam mounting portion 10, which mounts the two ends 5a of the crossbeam member 5 in the left-right direction; a leg mounting portion 11, which mounts the upper part of the leg 7; a frame mounting portion 12, which mounts the upper end of the pedal frame 8; and an instrument mounting portion 13, which positions and positions the lower surface of the keyboard instrument 1. The crossbeam mounting portion 10 is inserted from above by the left-right, i.e., lateral ends 5a of the crossbeam member 5 and secured by multiple screws 5b (see reference). Figure 2 , Figure 6It is installed on the top and bottom surfaces and the front and back sides.

[0019] like Figures 5-8 As shown, the leg mounting portion 11 is formed in an L-shape. This leg mounting portion 11 has a first bearing surface 11a and a second bearing surface 11b that are orthogonal to each other and mount the leg portion 7. The first bearing surface 11a of the leg mounting portion 11 extends obliquely downward from the inside of the keyboard instrument 1 towards the outside. The second bearing surface 11b of the leg mounting portion 11 extends obliquely downward towards the front of the keyboard instrument 1 in the short-side direction, i.e., the front-rear direction. Furthermore, the first bearing surface 11a and the second bearing surface 11b are not necessarily orthogonal; they may also intersect each other.

[0020] In this case, such as Figure 8 As shown, on the outer surface of the leg mounting portion 11, opposite to the first bearing surface 11a, a plurality of ribs 11c as reinforcing members are provided along the vertical direction. At the upper and lower portions of the first bearing surface 11a (in... Figure 8 (Only the lower part is shown) First mounting holes 11d are provided, which are located between a plurality of ribs 11c that serve as reinforcing members. A second mounting hole 11e is provided approximately at the middle of the second bearing surface 11b in the vertical direction. In addition, at the upper corner of the leg 7, an L-shaped reinforcing metal member 7a, which is orthogonal to the first bearing surface 11a and the second bearing surface 11b of the leg mounting part 11, is installed by a plurality of screws 7b. In addition, the reinforcing members are not limited to ribs; as long as they have a reinforcing effect, they can also be struts, brackets, reinforcing ribs, etc.

[0021] like Figure 8 As shown, the reinforcing metal member 7a is provided with a first mounting surface 7d opposite to the first bearing surface 11a of the leg mounting portion 11 and a second mounting surface 7e opposite to the second bearing surface 11b of the leg mounting portion 11. The first mounting surface 7d of the reinforcing metal member 7a is provided with two upper and lower first threaded holes 7f corresponding to the two first mounting holes 11d of the first bearing surface 11a of the leg mounting portion 11. In this case, a locking protrusion 7h is provided at the upper end of the first mounting surface 7d of the reinforcing metal member 7a, which engages with a locking recess (not shown) provided on the first bearing surface 11a of the leg mounting portion 11. Furthermore, the second mounting surface 7e of the reinforcing metal member 7a is provided with a second threaded hole 7g corresponding to the second mounting hole 11e of the second bearing surface 11b of the leg mounting portion 11.

[0022] Therefore, as Figure 8As shown, when the reinforcing metal member 7a of the upper part of the leg 7 is disposed inside the leg mounting portion 11 of the connecting structure member 6, the two mutually orthogonal surfaces of the reinforcing metal member 7a, namely the first mounting surface 7d and the second mounting surface 7e, face the two mutually orthogonal surfaces of the leg mounting portion 11, namely the first bearing surface 11a and the second bearing surface 11b. Therefore, the reinforcing metal member 7a is covered and hidden by the mutually orthogonal surfaces of the first bearing surface 11a and the second bearing surface 11b of the connecting structure member 6, making it invisible from the outside. In this case, the two first threaded holes 7f of the reinforcing metal member 7a correspond to the two first mounting holes 11d (one not shown) of the first bearing surface 11a, and the second threaded hole 7g of the reinforcing metal member 7a corresponds to the second mounting hole 11e of the second bearing surface 11b. In addition, the engaging protrusion 7h of the reinforcing metal member 7a is mounted and engaged with the engaging recess (not shown) of the first bearing surface 11a.

[0023] Therefore, as Figure 7 and Figure 8 As shown, in leg 7, two threaded members (not shown) serving as fastening components engage with two first threaded holes 7f of the first mounting surface 7d of the reinforcing metal member 7a through first mounting holes 11d of the first bearing surface 11a, while the other threaded member 15 (see reference) Figure 7 The second mounting hole 11e of the second bearing surface 11b is screwed into the second threaded hole 7g of the second mounting surface 7e of the reinforcing metal member 7a. Thus, the two threaded members (not shown) of one side of the leg 7 and the threaded member 15 of the other side are respectively fastened to the reinforcing metal member 7a, thereby being installed on the leg mounting portion 11 of the connecting structure member 6.

[0024] That is, such as Figures 5-8 As shown, when the two legs 7 are respectively installed on the leg mounting portions 11 of the connecting structural members 6 located on both sides of the cross frame member 5 via two threaded members (not shown) on one side and threaded members 15 on the other side, as... Figure 3 as well as Figure 4 As shown, it extends diagonally downwards towards the outside of the keyboard instrument 1 and towards the front of the short side of the keyboard instrument 1, i.e., in the front-back direction, and expands outwards and forwards towards the outside of the keyboard instrument 1.

[0025] On the other hand, such as Figures 5-7 As shown, the frame mounting portion 12 of the connecting structural member 6 includes a pressing metal member 12a that presses the upper end of the pedal frame 8. This pressing metal member 12a is mounted to the frame mounting portion 12 by multiple screws (not shown) while the upper end of the pedal frame 8 is positioned and pressed against the frame mounting portion 12. In this case, as... Figure 2As shown, the pedal frame 8 consists of two rod-shaped components extending upwards in a roughly inverted trapezoidal shape from both sides of the pedal device 9 when viewed from the front of the keyboard instrument 1, (widening outwards as it moves upwards). Figure 3 and Figure 4 As shown, these pedal frames 8 are positioned behind the legs 7, extending diagonally downwards and backwards towards the rear of the short side of the keyboard instrument 1, i.e., in the front-back direction.

[0026] Furthermore, anti-slip members 14 are provided at two locations on both sides of the pedal frame 8 in the long side direction (left-right direction) of the pedal device 9, serving as contact members. These anti-slip members 14 are configured to contact the mounting surface S of the bracket 2 to prevent the bracket 2 from sliding. In this case, it is not necessary to provide anti-slip members 14 on the pedal frame 8; the lower part of the horizontally extending rod-shaped portion of the pedal frame 8 can also contact the mounting surface S.

[0027] like Figures 1-5 As shown, the pedal device 9 includes a box-shaped main body 9a that extends horizontally along the long side of the keyboard instrument 1, and three pedals 9b arranged horizontally along the long side of the main body 9a and protruding towards the front of the main body 9a. Each of these three pedals 9b has a protrusion 9c extending forward from the main body 9a. These protrusions 9c are equipped with adjustment members (not shown) for adjusting contact with the setting surface S.

[0028] Moreover, such as Figures 5-8 As shown, each instrument mounting portion 13 of the two connecting structural members 6 that mount the keyboard instrument 1 has a front mounting portion 13a extending towards the front of the keyboard instrument 1 and a side mounting portion 13b extending laterally towards the long side of the keyboard instrument 1. Each of the two front mounting portions 13a has a fixing hole 13c for threaded fixing to the lower surface of the end portion of the keyboard instrument 1 in the long side direction. Furthermore, each of the two side mounting portions 13b has a positioning pin 13d for positioning the lower surface of the keyboard instrument 1.

[0029] Next, the assembly of such a keyboard instrument assembly 100 will be described. In this case, firstly, the support 2 is assembled. At this time, connecting members 6 are installed at both ends of the horizontal frame 5 in the left and right directions. That is, each end 5a on both sides of the horizontal frame 5 is inserted from above into the cross frame mounting portion 10 of the two connecting members 6, and is installed on the upper and lower surfaces and the front and rear sides of each end 5a on both sides of the horizontal frame 5 by multiple screws 5b. In this state, the pedal frame 8 is installed on the frame mounting portion 12 of the connecting members 6 installed on the horizontal frame 5.

[0030] At this time, the pedal device 9 is pre-installed on the pedal frame 8, and anti-slip members 14 are installed on both sides of the pedal frame 8 located on both sides of the pedal device 9. Then, the upper ends 8a on both sides of the pedal frame 8 are oriented upwards, and the pedal frame 8 is laid flat on the floor or other mounting surface S. In this state, the frame mounting portions 12 of the two connecting members 6 are installed on each upper end 8a of the pedal frame 8 on both sides. In this case, the upper end 8a of the pedal frame 8 is positioned on the frame mounting portion 12 of the connecting member 6 and pressed down using the pressing metal member 12a. In this state, the pressing metal member 12a is installed on the frame mounting portion 12 using multiple screws (not shown).

[0031] Thus, with the pedal frame 8 laid flat on a surface S such as the floor, when the cross frame 5 is installed on the pedal frame 8 via two connecting members 6, the leg mounting portions 11 of each of the two connecting members 6 are arranged in a state of tilting upwards. In this state, legs 7 are installed on the leg mounting portions 11 of the two connecting members 6 installed at both ends of the cross frame 5. At this time, L-shaped reinforcing metal parts 7a are pre-installed at the upper corners of the legs 7 using multiple screws 7b.

[0032] In this state, the engaging protrusion 7h of the reinforcing metal member 7a is mounted and engaged with the engaging recess of the first bearing surface 11a. With the setting position roughly determined, the L-shaped reinforcing metal member 7a, pre-installed on the upper part of the leg 7, is positioned inside the L-shaped leg mounting portion 11 of the connecting structure member 6, such that the mutually orthogonal first mounting surface 7d and second mounting surface 7e of the reinforcing metal member 7a face the mutually orthogonal first bearing surface 11a and second bearing surface 11b of the leg mounting portion 11. In this state, the two first threaded holes 7f of the reinforcing metal member 7a correspond to the two first mounting holes 11d of the first bearing surface 11a, and the second threaded hole 7g of the reinforcing metal member 7a corresponds to the second mounting hole 11e of the second bearing surface 11b. Thus, the reinforcing metal member 7a is covered and hidden by the mutually orthogonal first bearing surface 11a and second bearing surface 11b of the leg mounting portion 11 of the connecting structure member 6, making it invisible from the outside.

[0033] Furthermore, two threaded members (not shown) serving as fastening members are screwed into two first threaded holes 7f provided on the first mounting surface 7d of the reinforcing metal member 7a via the first mounting holes 11d on the first bearing surface 11a, and the other threaded member 15 is screwed into the second threaded hole 7g via the second mounting hole 11e on the second bearing surface 11b. In this state, when the two threaded members (not shown) of one side and the threaded member 15 of the other side are fastened respectively, the legs 7 are mounted on the leg mounting portion 11 of the connecting structure member 6. Thus, the two legs 7 and the pedal frame 8 are assembled to form a support 2 that supports the front and rear of the keyboard instrument 1.

[0034] In this state, when the bracket 2 is erected on the floor or other mounting surface S via the two legs 7 and the pedal frame 8, as... Figure 3 and Figure 4 As shown, the two legs 7 extend diagonally downwards towards the outside of the keyboard instrument 1 and towards the front of the keyboard instrument 1 along its short side (i.e., in the front-back direction), expanding outwards and forwards. Specifically, as... Figure 2 As shown, the two legs 7 are configured such that the distance L2 on the floor or other surface S side is longer than the distance L1 on the keyboard side. Additionally, as... Figure 4 As shown, when viewed from the left and right, the distance between the keyboard side of the leg 7 and the floor or other mounting surface S is L3, extending towards the front of the keyboard instrument 1. Thus, the two legs 7 expand towards the oblique front of the keyboard instrument 1, supporting the front of the keyboard instrument 1. Furthermore, at this time, the pedal frame 8, composed of two rod-shaped members, expands towards the rear of the keyboard instrument 1 when positioned behind each leg 7, supporting the rear of the keyboard instrument 1. Additionally, the structure provides a stable support, preventing it from tipping over when pressed from the front of the keyboard instrument 1.

[0035] Furthermore, the two sides of the lower surface of the keyboard instrument 1 in the long side direction (i.e., the left-right direction) are positioned on the instrument mounting portions 13 of the two connecting structural members 6 of the bracket 2. At this time, the lower surfaces of the keyboard instrument 1 in the left-right direction are positioned by the positioning pins 13d provided on the side mounting portions 13b of the two instrument mounting portions 13. In this state, when threaded members (not shown) are screwed into the lower surface of the keyboard instrument 1 from below through the fixing holes 13c of the two front mounting portions 13a, the keyboard instrument 1 is mounted on the bracket 2. In this state, the contact state of the pedal device 9 with the mounting surface S is adjusted by the setting adjustment member (not shown). Thus, the keyboard instrument assembly 100 is assembled.

[0036] Thus, the support 2 of the keyboard instrument assembly 100 includes legs 7 supporting the front of the keyboard instrument 1, a pedal frame 8 disposed at the rear of the keyboard instrument 1, and a pedal device 9 fixed to the pedal frame 8, the pedal frame 8 supporting the rear of the keyboard instrument 1. For example, in the four-legged support structure described in Japanese Patent Application Publication No. 2023-157063, there is a problem that the number of parts such as screws increases accordingly with the number of legs, resulting in a complex structure and complicated assembly. On the other hand, the support 2 of the keyboard instrument assembly 100 can reduce the number of parts.

[0037] That is, in the support 2 of the keyboard instrument assembly 100, since the pedal frame 8 is used as the rear leg, the rear leg, which is part of other components, can be omitted, thereby reducing the number of parts. Furthermore, since there is no need to provide a leg mounting part for mounting the rear leg in the connecting member 6, the structure can be simplified. As a result, the assembly operation can be simplified, thus improving productivity.

[0038] In addition, in the support 2 of the keyboard instrument assembly 100, there are two legs 7, which are arranged on the front side of the keyboard instrument 1 in the long side direction, i.e., the left and right direction, and expand outwards from the keyboard instrument 1. Thus, the front side of the keyboard instrument 1 can be reliably and well supported in a stable state by the two legs 7.

[0039] Furthermore, in the support 2 of the keyboard instrument assembly 100, the pedal frame 8 is positioned behind the legs 7 and extends towards the rear of the keyboard instrument 1, thereby reliably and securely supporting the rear of the keyboard instrument 1 in a stable state. Thus, in the support 2 of the keyboard instrument assembly 100, the front of the keyboard instrument 1 is supported by the two legs 7, and the rear of the keyboard instrument 1 is supported by the pedal frame 8, allowing the keyboard instrument 1 to be reliably and securely supported in a stable state by these legs 7 and the pedal frame 8.

[0040] In this case, in the support 2 of the keyboard instrument assembly 100, the pedal frame 8 consists of two rod-shaped members extending upwards in a roughly inverted trapezoidal shape from both sides of the pedal device 9 in the left-right direction when viewed from the front of the keyboard instrument 1. This allows for a minimum contact area required to ensure stability when installed on a surface S such as a floor, thus contributing to space reduction. Furthermore, at this time, as... Figure 4 As shown, when viewed from the left and right, the distance between the keyboard side of the pedal frame 8 and the S-side (such as the floor) is L4, extending towards the rear of the keyboard instrument 1. Therefore, the pedal frame 8 expands towards the rear of the keyboard instrument 1, supporting the rear of the instrument 1. Furthermore, it is not easily tipped over when pressed from the rear of the keyboard instrument 1, providing a stable support.

[0041] In addition, in the support 2 of the keyboard instrument assembly 100, the pedal frame 8 has a contact member, namely an anti-slip member 14, which is disposed in contact with the setting surface S. The anti-slip member 14 can prevent the pedal frame 8 from sliding on the setting surface S and can also prevent the pedal frame 8 from damaging the setting surface S.

[0042] Moreover, such as Figure 2As shown, in the support 2 of the keyboard instrument assembly 100, in the plan view viewed from the front, the distance L5 between the front ends 8b of the rod-shaped portions on both sides of the horizontally extending pedal frame 8 is shorter than the distance L6 between the upper ends 8a on both sides of the pedal frame 8. Furthermore, the distance L5 between the two rod-shaped members of the pedal frame 8 widens to L6 towards the keyboard instrument side. As a result, the distance L6 (the width of the pedal frame 8 on the keyboard instrument side) becomes approximately the same as the distance L1 between the two legs 7 on the keyboard instrument side. Therefore, the lateral width of the pedal frame 8 can be made sufficiently long, thereby reliably and well supporting the rear side of the keyboard instrument 1 in a stable state, and preventing the player's knees from touching the pedal frame 8 during performance.

[0043] Furthermore, in the above embodiments, the case where the pedal frame 8 is formed into a generally inverted trapezoidal shape has been described, but this disclosure is not limited to this, and it may also be formed into a quadrilateral shape, a rectangular shape, or other shapes.

[0044] In addition, this disclosure is not limited to the assembly method of the above-described embodiments; the leg 7 may be assembled first, and then the pedal frame 8 may be installed.

[0045] Furthermore, in the above embodiments, the case where the support 2 is applied to the keyboard instrument 1 has been described, but this disclosure is not limited to keyboard instruments, and can also be applied to zithers, qins, yangqins, DJ controllers and MIDI controllers.
