DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 shows an instrument stand 100 (instrument stand) that supports a keyboard instrument 10 (instrument) having a rectangular parallelepiped shape indicated by a two-dot chain line. A keyboard instrument set 1 includes the keyboard instrument 10 and the stand 100. The stand 100 is provided with a pedal device 200 having three pedals 210. In the following description, the front-to-back direction of the pedal 210 (the front-to-back direction of the keys (not shown) of the keyboard instrument 10) is referred to as the front-to-back direction FB, the front is referred to as the front side F (the performer's side), the rear is referred to as the rear side B, and the direction in which the pedals 210 are arranged (the direction in which the keys (not shown) of the keyboard instrument 10 are arranged) is referred to as the left-to-right direction LR, with the left as viewed from the front of the pedal device 200 being the left side L and the right as viewed from the right side R. In addition, in the up-down direction UL of the pedal device 200, the top is referred to as the upper side Up and the bottom is referred to as the lower side Lo. In this embodiment, the object supported by the stand 100 is the keyboard instrument 10, but it may also be another instrument.

[0011] 1 and 2, the stand 100 includes a horizontal member 150 having a rectangular cylindrical shape that is long in the left-right direction LR, two connecting members 300 provided at both ends of the horizontal member 150, and a first leg member 110 and a second leg member 120 provided on each connecting member 300. The pedal device 200 is attached to the connecting member 300 via a pedal frame 250 in the shape of a solid round bar. The connecting member 300 includes a horizontal member fixing portion 320, an instrument mounting portion 330, a pedal frame fixing portion 340, and a leg mounting portion 310.

[0012] The stand 100 (connecting member 300) is substantially symmetrical when viewed in the front-rear direction FB. Therefore, in the following description, attention will be focused on the connecting member 300 on the left side L.

[0013] As shown in FIGS. 3 to 5, the connecting member 300 is provided with a leg attachment portion 310 having a substantially hexagonal cylindrical shape with a bottom at its outer end in the left-right direction LR (the left side L in the connecting member 300 on the left side L). In other words, the leg attachment portion 310 is disposed further outward in the left-right direction LR than the pedal frame fixing portion 340 and the instrument fixing portion 330. The leg attachment portion 310 has a first leg fixing surface 311 that is parallel to the up-down direction UL and has a normal tilted approximately 45 degrees from the left-right direction LR to the front side F, a second leg fixing surface 312 that intersects the first leg fixing surface 311 at approximately 90 degrees, and a connection surface 313 that is approximately parallel to the front-to-back direction FB and connects the first leg fixing surface 311 and the second leg fixing surface 312. A first leg member 110 having a substantially rectangular horizontal cross section is fixed to the first leg fixing surface 311.

[0014] The first leg member 110 is attached to the first leg fixing surface 311 by a fixing surface that is parallel to the up-down direction UL and is provided on the first leg member 110, which is brought into face-to-face contact with the first leg fixing surface 311 and screwed in place. Similarly, a second leg member 120 that has approximately the same shape as the first leg member 110 is fixed to the second leg fixing surface 312.

[0015] Note that a knee brace member 130 is provided between the first leg member 110 and the second leg member 120 for reinforcement.

[0016] A groove-shaped horizontal member fixing portion 320 is provided on the inside of the leg mounting portion 310 of the connecting member 300 in the left-right direction LR (on the right side R in the connecting member 300 on the left side L) via a recess 315 for removing material. As shown in FIG. 3, the horizontal member fixing portion 320 is provided with two boss-shaped fixing portions 321 that stand upright from the bottom surface of the groove in a tapered shape. As shown in FIG. 6, the boss-shaped fixing portions 321 are arranged on the horizontal member fixing portion 320 so that their centers, i.e., axis CL2, are offset by a distance D1 to the rear side B from the center CL1 in the front-rear direction FB of the stand 100. In this embodiment, as illustrated in FIG. 2, the first connecting member 300 is fixed to one end (right side) of the horizontal member 150, and the second connecting member 300 is fixed to the other end (left side) of the horizontal member 150. Because this boss-shaped fixing portion 321 is provided on the connecting member 300 side, the second connecting member 300 does not fit into one end (right side) of the horizontal member 150. Similarly, the first connecting member 300 does not fit into the other end (left side) of the horizontal member 150. This is because, during assembly, the spacer 30 needs to be attached with the spacer insertion hole 153 in the horizontal member 150 aligned with the round hole 322 in the connecting member 300. A female thread is provided at the tip of the boss-shaped fixing portion 321.

[0017] 3, two round holes 322 are provided in the wall portion on the front side F of the groove of the horizontal member fixing portion 320. Female thread portions 323 are provided coaxially with each of the round holes 322 in the wall portion on the rear side of the groove of the horizontal member fixing portion 320.

[0018] The cross member 150 is formed in a rectangular cylindrical shape. Two screw holes 151 aligned in the left-right direction LR are formed in the upper surface of each end of the cross member 150. Boss insertion holes 152 coaxial with the screw holes 151 are formed in the lower surface of each end of the cross member 150. Two spacer insertion holes 153 aligned in the left-right direction LR are formed in the front surface of each end of the cross member 150. Screw holes 154 coaxial with the spacer insertion holes 153 are formed in the rear surface of each end of the cross member 150.

[0019] 6, the boss-shaped fixing portion 321 of the horizontal member fixing portion 320 is inserted into the boss insertion hole 152 of the horizontal member 150. Then, the screw member 31 is screwed into the female thread portion of the boss-shaped fixing portion 321 through the screw hole portion 151.

[0020] 3, a tapered, cylindrical, resin spacer 30 with a bottom (the innermost side when viewed from the front when the spacer 30 is fitted into the connecting member 300) is inserted into the round hole 322 of the connecting member 300 and the spacer insertion hole 153 of the cross member 150 from the bottom side. A screw member 32, which is a screw that prevents mechanical loosening such as a double sems screw (a screw fitted with a flat washer including a spring washer), is threadedly engaged with the female threaded portion 323 via the bottom of the spacer 30. In this manner, the cross member 150 is fixed to the connecting member 300.

[0021] The spacer 30 guides the screw member 32, making it easier to tighten the screw member 32 into the female thread portion 323. The spacer 30 also reduces the risk of finger injuries that may occur when tightening a screw to fasten the connecting member 300 and the keyboard instrument 10 due to burrs that may form on the inside of the round hole portion 322 or the spacer insertion hole portion 153. The spacer 30 also reduces the risk of fingers or the like getting caught in the round hole portion 322 when attaching a screw member through the screw hole portion 331b1 of the front contact surface 331b, which will be described later.

[0022] As shown in FIGS. 3 and 4 , the front side F and rear side B of the horizontal member fixing portion 320 (horizontal member 150) are provided with an instrument mounting portion 330 including a front instrument mounting portion 331 and a rear instrument mounting portion 332. The front instrument mounting portion 331 on the front side F includes a front base portion 331a. The front base portion 331a is a generally rectangular plate that is elongated in the left-right direction with its flat surface facing the up-down direction UL, and is provided to protrude from the upper end of the wall portion of the front side F of the horizontal member fixing portion 320 to the front side F. A portion of the front base portion 331a is arranged contiguous to a polygonal portion serving as a leg mounting portion 310 provided on one end of the connecting member 300. As a result, the stand 100 is stable by supporting the keyboard instrument 10 on both left and right ends, allowing the keyboard instrument 10 to be well supported. Furthermore, by connecting the front base portion 331a to the leg attachment portion 310, even when the keyboard instrument 10 and the connecting member 300 are fixed together to support the keyboard instrument 10, flexure of the front base portion 331a is reduced.

[0023] A front contact surface 331b, which is a flat surface that protrudes slightly from the upper surface of the front base portion 331a, is provided on the inner side (the right side R in the case of the connecting member 300 on the left side L). The front contact surface 331b is provided with a through-hole 331b1. A positioning pin 331c is provided on the outer side of the front contact surface 331b (the left side L in the case of the connecting member 300 on the left side L). The corner of the front base portion 331a facing the positioning pin 331c is chamfered to a substantially C-shape.

[0024] The rear instrument mounting portion 332 on the rear side B includes a rear base portion 332a. The rear base portion 332a is a generally right-angled trapezoidal plate with its flat surface facing the up-down direction UL and its inclined surface facing outward, and is provided so as to protrude from the upper end of the wall portion of the rear side B of the horizontal member fixing portion 320 to the rear side B. A rear abutment surface 332b, which is a generally rectangular flat surface elongated in the left-right direction LR and protrudes slightly from the upper surface of the rear base portion 332a, is provided at the rear end of the rear base portion 332a. The rear abutment surface 332b is provided with a screw hole 332b1 serving as a through-hole. The rear base portion 332a is provided with a generally rectangular hole 332c1 and a generally triangular hole 332c2. A portion of the rear base portion 332a is arranged to be connected to a polygonal portion serving as the leg mounting portion 310 provided on the other end of the connecting member 300. As a result, similar to the front base portion 331a, the bending of the rear base portion 332a when the keyboard instrument 10 is attached to the stand 100 is reduced.

[0025] 6, a distance L2 from the center CL1 of the stand 100 in the front-to-rear direction FB to the rear edge of the rear base portion 332a is sufficiently larger than a distance L1 from the center CL1 to the front edge of the front base portion 331a (L2>L1). Therefore, the rear instrument mounting portion 332 (rear base portion 332a) is larger than the front instrument mounting portion 331 (front base portion 331a).

[0026] Additionally, the front contact surface 331b and the rear contact surface 332b come into contact with predetermined locations on the corresponding underside of the keyboard instrument 10. Therefore, there are gaps between the upper surface of the connecting member 300 excluding the front contact surface 331b and the rear contact surface 332b, and the upper surfaces of the first leg member 110 and the second leg member 120 and the underside of the keyboard instrument 10.

[0027] In keyboard instrument 10, rear side B, where the circuit board, speakers, etc. are located, is heavier than front side F, where the white and black keys are located. Therefore, the center of gravity of keyboard instrument 10 is on rear side B in the front-to-rear direction FB. Since stand 100 supports the rear side of keyboard instrument 10 with rear instrument mounting portion 332, which is larger than front instrument mounting portion 331, it can support keyboard instrument 10 more stably.

[0028] 5 and 6, the connecting member 300 is provided with an extension portion 350 having a leg mounting surface that extends downward Lo from the first leg fixing surface 311 and the second leg fixing surface 312. The extension portion 350, the first leg member 110, and the second leg member 120 are fixed by screw members 33. The connecting member 300 is also provided with two reinforcing ribs 360 that extend from the lower surface of the leg mounting portion 310 to the back surface of the extension portion 350.

[0029] As shown in Fig. 4, a pedal frame fixing portion 340 is provided on the rear side B of the cross member 150, inside the rear instrument mounting portion 332 of the instrument mounting portion 330 in the left-right direction LR (on the right side R in the case of the connecting member 300 on the left side L). Here, as shown in Fig. 1, the pedal frames 250 are provided on the left and right, respectively, and include an upper end portion 251, a middle portion 252, and a lower end portion 253.

[0030] The upper end 251 is disposed with its axis oriented in the front-to-rear direction FB. The middle portion 252 is connected to the upper end 251 via a bent portion and extends downward and inward. The lower end 253 is connected to the lower end of the middle portion 252 via a bent portion and is connected to the left and right side surfaces of the pedal device 200 with its axis oriented in the left-to-right direction LR. The pedal frame 250 is made of a solid steel material, and as shown in FIG. 4, an engagement hole 251a is provided at the upper end, penetrating in the up-down direction UL.

[0031] 4 and 5, the pedal frame fixing portion 340 is provided with an arc-shaped groove 341 extending in the front-rear direction FB so that the upper end portion 251 of the pedal frame 250 can be placed thereon. A boss 342 is provided in the arc-shaped groove 341. A total of four female threads 343 are provided in two wall portions 345 of the arc-shaped groove 341 in the left-right direction LR.

[0032] The pedal frame 250 is fixed to the pedal frame fixing portion 340 by inserting the boss 342 into the engagement hole 251a in the upper end portion 251 of the pedal frame 250 and placing the upper end portion 251 in the arc-shaped groove portion 341. Then, a fixing plate 344 having a bulge 344a shaped to match the outline of the pedal frame 250 and four screw holes 344b is provided on the upper side Up of the upper end portion 251, and the screw member 34 is screwed into the female screw portion 343 via the screw holes 344b to fix the fixing plate 344.

[0033] 7, a gap S1 is provided between the lower surface of the fixing plate 344 and the upper surface of the wall portion 345. Therefore, by tightening the screw member 34, a resilient force is generated in the fixing plate 344. Then, the upper end portion 251 (pedal frame 250) is pressed against the arc-shaped groove portion 341 by the fixing plate 344 and fixed thereto.

[0034] As described above, in the embodiment of the present invention, the stand 100 (musical instrument stand) comprises a connecting member 300 to which the cross member 150 is fixed, the connecting member 300 including an instrument mounting portion 330, a pedal frame fixing portion 340, and a leg mounting portion 310.

[0035] This allows the keyboard instrument 10, pedal device 200, first leg member 110 and second leg member 120 to be attached to the connecting member 300 attached to the cross member 150, so that the keyboard instrument 10, pedal device 200 and stand 100 can be integrated and provided in a compact manner.

[0036] Furthermore, the pedal frame fixing portion 340 is disposed on the rear side B of the cross member 150 when viewed from the performer's side. This allows the pedal frame 250 to be easily extended to the rear side B and then to the lower side Lo, so that the pedal device 200 can be conveniently disposed on the rear side B of the stand 100, and the pedal device 200 can be disposed in a position that is easy to operate even for a compact keyboard instrument 10. In the case of a compact keyboard instrument 10, if the pedal device 200 is disposed directly below the keyboard instrument 10 or on the front side F of the keyboard instrument 10, it is difficult to operate the pedal device 200 while playing by striking keys.

[0037] The connecting member 300 is provided with a pedal frame fixing portion 340. The connecting member 300 includes a cross member fixing portion 320, an instrument mounting portion 330, etc., the pedal frame fixing portion 340, and a leg mounting portion 310. The main components constituting the stand 100, namely the cross member 150, the leg members (first leg member 110, second leg member 120), and the pedal frame 250, are all fixed to the connecting member 300. This connecting member 300 makes it possible to provide a compact and excellent stand. Furthermore, because this connecting member 300 has a polygonal leg mounting portion 310, leg members (first leg member 110, second leg member 120) with rectangular cross sections can be fixed to the connecting member 300.

[0038] Additionally, the pedal frame fixing portion 340 is disposed inside the instrument mounting portion 330 in the left-right direction LR. This allows the pedal frame fixing portion 340 to be provided while avoiding interference between the pedal frame 250 and the instrument mounting portion 330.

[0039] Furthermore, the leg attachment portion 310 is disposed further outward in the left-right direction LR than the pedal frame fixing portion 340 and the instrument attachment portion 330. This increases the degree of freedom in the design of the leg members, as in the first leg member 110 and the second leg member 120, which are disposed so as to spread apart when viewed from both the front-rear direction FB and the left-right direction LR.

[0040] Furthermore, the instrument mounting sections 330 are provided at the front and rear of the cross member 150 as a front instrument mounting section 331 and a rear instrument mounting section 332, respectively, when viewed from the performer's side. As a result, even if the center of gravity of the keyboard instrument 10 is not at the center of the outer shape (case) of the keyboard instrument 10, the keyboard instrument 10 can be positioned offset from the center of the stand 100, and therefore can be stably supported by the stand 100.

[0041] The instrument mounting section 330 includes a front instrument mounting section 331 that is disposed on the front side F of the cross member 150 as viewed from the performer's side, and a rear instrument mounting section 332 that is disposed on the rear side B of the cross member 150 and is larger than the front instrument mounting section 331. This allows the stand 100 to stably support even a keyboard instrument 10 that has its center of gravity on the rear side B.

[0042] The instrument mounting portion 330 also includes a positioning pin 331c for positioning the instrument to be mounted, which makes it easy to mount the keyboard instrument 10 on the stand 100.

[0043] The stand 100 also includes a cross member 150 and a leg member including a first leg member 110 fixed to the connecting member 300. This makes it possible to provide a good musical instrument stand 100 that includes leg members.

[0044] The keyboard instrument set 1 also includes the stand 100 and the keyboard instrument 10. This makes it possible to provide a keyboard instrument set 1 that includes a good quality stand 100.

[0045] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
