Description

  The present invention relates to a leg device for a musical instrument stand suitable for a hi-hat stand for a cymbal performance.

  For example, a hi-hat stand supports a stand main body with two or more stand legs and a pedal frame, and each stand leg is attached to the stand main body via a support so as to be foldable. Three stand legs are arranged around the stand main body at substantially equal angles (120 °), and support the stand main body in a stable state together with a pedal frame arranged between the stand legs.

  However, since the pedal is arranged between the three stand legs spaced 120 ° apart, the pedal area becomes complicated and the foot hits the stand leg when the pedal is operated, especially when playing multiple instruments side by side. There was a problem that the legs obstructed the setting. In particular, when setting a plurality of musical instruments such as bass drums and snare drums adjacent to the hi-hat stand, the stand legs may be in the way and cannot be brought close to each other.

  In contrast, the number of stand legs is reduced to two (for example, refer to Patent Documents 1 and 2), and the support to which the stand legs are attached is centered on the axis of the stand body together with the stand legs. It can be rotated left and right, so that when the stand leg gets in the way during setting, it can be rotated to the left and right to avoid obstacles and adjusted to a preferred position where the foot does not hit (For example, refer to Patent Documents 3 and 4).

  However, even if the number of stand legs is reduced to two, if the position is fixed, adjustment may not be effective during setting, and it may become an obstacle. The thing that avoids obstruction is also relatively effective compared to the case where the position is fixed, but it is still not sufficient, and it may become an obstacle even if it is rotated. If the stand leg is rotated left and right together with the support in this way, the stand main body may become unstable due to the relationship with the pedal frame.

Then, when the pedal 41 is depressed, the lifting rod 72 is pulled down against the coil spring, and the upper cymbal 81 is lowered together with the lifting rod 72 to hit the lower cymbal 80 supported by the cymbal support 73. .

  The leg device 1 includes two stand legs 2 and 2 extending from the stand body 7 to the floor, and supports 3A and 3B for attaching the stand legs 2 and 2 to the stand body 7 in a foldable manner. The stand body 7 is supported together with the pedal device 4 connected to the lower end of the body 7. Each stand leg 2 has a lower end installed on the floor and an upper end 20a attached to the lower pipe 70 of the stand body 7 via the support 3A, and one end connected to the middle part of the support leg 20. The other end 21a is configured by a connecting stay 21 attached to the lower pipe 70 via the support 3B at a position below the upper end of the support leg 20.

  The first support 3A is slidably attached along the axial direction of the lower pipe 70 of the stand body 7, and the upper end 20a of the support leg 20 is pivoted to the first support 3A so as to be vertically rotatable. The other end 21a of the connecting stay 21 is also pivotally supported by the lower second support 3B so as to be vertically rotatable. By sliding the first support 3 </ b> A upward, the posture of the stand leg 2 is changed to the folding posture along the lower pipe 70 as shown in FIG. 18. In addition, you may comprise a stand leg as another structure so that it can fold with one or two or more support tools. The leg device 1 of this example is provided with two stand legs 2, but may be provided with three or more as will be described later.

  As shown in FIGS. 2 to 7, the first support 3 </ b> A is rotatable to the left and right around the central axis of the lower pipe 70 with respect to the outer peripheral surface of the lower pipe 70 of the stand body 7. The support tool main body 30 is slidably attached in a direction along the direction of the support tool, and one end of the support tool main body 30 can be rotated in the left-right direction around the axis parallel to the axis of the lower pipe 70 on the outer peripheral portion 30a. A connecting member provided with a bearing portion 32a pivotally attached and pivotally attached at the other end to the end 2a of the stand leg 2 so as to be pivotable in the vertical direction around a shaft 32d perpendicular to the axis of the lower pipe 70. 32 and 32 are comprised.

  As shown in FIG. 2, the angle θ <b> 1 for rotating the support tool body 30 to the left and right with respect to the lower pipe 70 and the angles θ <b> 2 and θ <b> 3 for turning the connecting members 32 to the left and right with respect to the support tool body 30 are adjusted. By doing so, it is possible to adjust both the left-right rotation position around the axis of the lower pipe 70 in each stand leg 2 and the left-right rotation angle around the axis of the outer peripheral portion 30a of the support body 30. it can.

  More specifically, the support body 30 has a substantially C-shaped inner peripheral surface 30b substantially parallel to the outer peripheral surface of the lower pipe 70 as shown in FIGS. Bearing portions 55 and 55 that support a shaft portion 32b that is provided at one end portion of the connecting member 32 and extends parallel to the shaft of the lower pipe 70 so as to be rotatable left and right, and the inner peripheral surface side toward the shaft center of the lower pipe 70. A support member 54 having a screw hole 56 provided through the outer periphery of the stand body 7, and a threaded end of the screw threaded through the screw hole 56. A fastening screw 33A for pressing the surface and bearing portions 31a, 31a, and at least a position opposite to the fastening screw 33A with respect to the lower pipe 70 from an inner circumferential surface substantially parallel to the outer circumferential surface of the lower pipe 70 The stopper which has the stopper part 31b which becomes It is more configuration as member 31.

  The bearing portion 31a of the stopper member 31 faces the bearing portion 55 of the support member 54, and receives the shaft portion 32b of each connecting member 32 together with the bearing portion 55 so as to be supported so as to be able to turn left and right. In this example, the two stopper members 31 are provided on the top and bottom so as to sandwich the connecting member 32 from above and below, but it is also possible to form a single member.

  The shaft portion 32b of the connecting member 32 is formed by press-fitting a pin 53 into a through hole 32c formed at one end portion of the connecting member 32, and a portion protruding up and down of the pin 53 is used as a shaft portion, and is shown in FIG. As described above, when the abutting plate 36, the pressing member 35, and the stopper member 31 are incorporated into the support member 54, the pins 53 are inserted into the bearing portions 55 and 31 a of the support member 54 and the stopper member 31 and the through holes are inserted. By press-fitting into 32c, the connecting member 32 is assembled so as to be rotatable left and right.

  Here, you may fix by screwing etc. instead of press fit. Further, the shaft portion 32b may be integrally formed as long as it can be assembled to the support member 54. The bearing portion 55 of the outer peripheral portion 30a that supports the shaft portion 32b is provided with a pair of upper and lower annular support portions 55a and 55a that pivotally support the shaft portion 32b at both ends of a substantially C-shaped support member 54, respectively. In addition, between the upper and lower annular support portions 55a and 55a, one end side of the connecting member 32 and the bearing portions 31a and 31a of the pair of upper and lower contact stopping members 31 and 31 are interposed.

  In this example, the screw hole 56 provided in the support member 54 includes a female screw of the nut 34 that is non-rotatably mounted in a groove portion 57 that is open on the inner peripheral side of the support member 54, and a through hole that communicates with the female screw and opens to the outer peripheral surface. The hole 58 is configured so that the fastening screw 33A is inserted through the through hole 58 and screwed into the female screw of the nut. In addition, the screw hole 56 may be directly drilled in the support member 54 in addition to forming the screw hole 56 from the female screw of the nut 34. The tightening screw 33A is a butterfly screw, and has a structure that can be easily operated when the angle of the leg is adjusted or folded.

  The pressing member 35 is a cylindrical synthetic resin molded body having an inner peripheral surface that is in direct contact with the outer peripheral surface of the lower pipe 70, and a support body that is formed in an annular shape from the support member 54 and the stopper member 31. 30 is mounted inside. On the side where the tip of the fastening screw 33A of the pressing member 35 abuts, a U-shaped slit comprising two through slit grooves extending in the circumferential direction over substantially a half circumference and a through slit groove extending in the axial direction connecting one end thereof. A groove 59 is formed, and a portion surrounded by the slit groove 59 forms an adhesion piece 60 that is pushed by the distal end portion of the fastening screw 33A and deforms inward while being reduced in diameter and is in close contact with the outer peripheral surface of the lower pipe 70. Yes. The pressing force by the fastening screw 33A acts on the outer peripheral surface of the lower pipe 70 through the contact piece 60, and smoothly and reliably frictionally locks the left-right rotation and the up-down slide operation.

  On the lower side of the contact piece 60 of the pressing member 35, a support base 61 for preventing fall is provided protruding from below to support the nut 34 that is inserted into the lower portion of the groove portion 57 and is also mounted on the groove portion 57. In addition, on the side where the stopper member 31 on the opposite side of the support base 61 abuts, a spacer protrusion 62 is provided so that the stopper members 31 are not exposed and displaced at a position between the two upper and lower stopper members 31. ing. The contact plate 36 is used to prevent a corner portion of the tip of the tightening screw 33A from being locally pressed and damaged by the pressing member 35, and to stably press, but it is of course possible to omit it. . Further, in this example, the fastening screw 33A and the stopper 31b of the stopper member 31 press the lower pipe 70 via the pressing member 35. However, such a pressing member 35 is omitted, and the stand main body directly. 7 (lower pipe 70) may be configured to be pressed.

  In such a support tool 3A, when the tightening screw 33A is tightened and the outer peripheral surface of the lower pipe 70 is pressed through the pressing member 35, the support member 54 moves in the direction in which the tightening screw 33A is present, and the bearing of the support member 54 is supported. The portion 55 draws the shaft portion 32b of the connecting member 32 in the direction, and the bearing portion 31a of the stopper member 31 supporting the shaft portion 32b is also drawn in the direction at the same time. The stopper 31b is stopped against the outer peripheral surface of the lower pipe 70 via the pressing member 35, and thereafter, a reaction force from the bearing 31a is generated on the shaft 32b.

That is, when the fastening screw 33A of the support tool body 30 is tightened, as shown in FIG. 13A, the pulling force F _b (F in the tightening screw direction by the support member 54 is applied to the shaft portion 32b of each connecting member 32. _c ) and the counter force f _b (f _c ) in the opposite direction by the stopper member 31 act, whereby each shaft portion 32b is fixed in a non-rotatable manner. Further, the outer peripheral surface of the lower pipe 70 includes a contact-stopping force f _a by abutting-stop portion 31b of the pressing force F _a the abutting stopping member 31 by screw tip clamping acts via the pressing member, thereby the The support body 30 is also fixed so that it cannot rotate and cannot slide up and down at the same time. That is, just by operating one tightening screw, as shown in FIGS. 6 and 7, the rotation of each connecting member 32 with respect to the support body 30, rotation with respect to the lower pipe 70 of the support body 30 and vertical sliding All the movements can be loosened or fixed in an adjustable manner.

In this example, each of the bearing portion 55 (annular support portion 55a) and the bearing portion 31a has a circular hole, and each has a structure capable of rotatably supporting the shaft portion 32b of the connecting member. At least the inner peripheral wall that rotatably supports the shaft portion 32b is provided on the side on which the pulling force F _b (F _c ) acts, and the shaft portion on the side on which at least the force f _b (f _c ) acts on the bearing portion 31a. A bearing having an inner peripheral wall that rotatably supports 32b and having a substantially circular hole formed between the inner peripheral wall of the bearing portion 55 and the inner peripheral wall of the bearing portion 31a in a state in which these are vertically stacked. Either one or both of the portions 55 and 31a may be holes other than a circle provided with at least the inner peripheral wall.

Further, in this example, the support member 54 has a substantially C-shaped inner peripheral surface. However, when the fastening screw 33A is tightened, the abutting portion 31b of the stopper member 31 is more than the inner peripheral surface of the support member 54. Any other shape can be used as long as it generates a drag force f _b (f _c ) on the shaft portion 32b, and has an oval annular inner peripheral surface as shown in FIG. 13 (b), for example. Things are also possible.

  In this example, the number of stand legs 2 is two. However, in the case where there are three or more stand legs, the rotation of each connecting member with respect to the support body by simply operating one tightening screw is also possible. It is possible to have a structure that can adjustably loosen or fix all the operations of the rotation and the vertical slide with respect to the lower pipe of the main body. FIG. 14A shows an example in which three stand legs are provided every 120 degrees. In this case, the pedal device does not necessarily have sufficient support strength as a leg. FIG. 14B is an example in which three stand legs are provided every 90 degrees, and the four legs are configured together with the pedal device.

In any case, three bearing portions of the support member 54 and three bearing portions of the stopper member 31 are provided, and similarly, the pulling force F _b (F _c , F _{d) in the} tightening screw direction by the support member 54 on the shaft portion 32b of each connecting member. ) And a resisting force f _b (f _c , f _d ) in the opposite direction by the stopper member 31, thereby fixing each shaft portion 32 b so as not to rotate, and tightening to the outer peripheral surface of the lower pipe 70 screw tip by the action of the contact-stopping force f _a by the pressing force F _a and the abutting-stop portion 31b of the abutting stopping member 31 by, thereby causing the support body 30 also vertically sliding fixed non simultaneously unrotatable and .

  Furthermore, in the case where there are three or more slide legs, instead of providing three bearing portions for supporting the shaft portions 32b of the respective connecting members in one stopper member 31, as shown in FIG. It is also possible to provide the stopper members 31 and 31 having two bearing portions between the adjacent shaft portions 32b and 32b excluding the portion where the tightening screw is provided.

In the case of the structure shown in FIG. 14C, when the tightening screw is tightened, each shaft portion 32b has a pulling force _Fb ( _Fc , _Fd ) in the direction of the tightening screw by the support member 54 and the stopper member 31. The forces f _b and (f _c1 and f _c2 and f _d ) in the opposite direction due to the above act on each other, and thereby each shaft portion 32b is fixed so as not to rotate. Further, the outer peripheral surface of the lower pipe 70, and the pressing force F _a and contact-stopping force by the stopper section 31b of the abutting stopping member 31 f _a1 (f _a2) acts via the pressing member by the screw tip tightening As a result, the support body 30 is also fixed so that it cannot rotate and cannot slide up and down at the same time.

  Further, similarly, when there are three or more slide legs, the support member 54 is not provided with three bearing portions for supporting the shaft portions 32b of the connecting members, but as shown in FIG. Is a member having a substantially C-shaped inner peripheral surface, and at least a bearing portion for supporting two shaft portions 32b and 32b sandwiching a portion with a fastening screw is provided, the others are omitted, and the bearing portion of the stopper member 31 is It is also possible to support only.

In the case of the structure shown in FIG. 14D, the shaft portion 32b supported only by the bearing portion of the stopper member 31 is pulled by the fastening screws 31, and the tensions f _d1 and f _d2 from the stopper members 31 and 31 are obtained. The abutting force f _a1 (f _a2 ) by the abutting portion 31b acts on the outer peripheral surface of the lower pipe on each of the abutting members 31 that are generated and fixed so as not to rotate and are connected to each other by the shaft portion 32b. The support body 30 is also fixed so that it cannot rotate and cannot slide up and down simultaneously. In this example, as in FIG. 14C, the two stopper members having two bearing portions are connected to each other. However, the stopper member may be constituted by one stopper member having three shaft portions. it can.

As another modification, for example, as shown in FIG. 15A, the stopper member 31 is omitted, and the pulling force F _{b in the} tightening screw direction by the support member 54 and the connecting member 32 are placed on the outer peripheral surface of the pressing member or the lower pipe. The shaft portion 32b may be fixed so as not to rotate by a drag generated by stopping. Further, as shown in FIG. 15 (b), each shaft portion 32 b may be directly pressed and fixed with a screw 64. Furthermore, in this example, a shaft portion 32b is provided at one end of the connecting member 32 and a bearing portion is provided on the support tool body 30 side so as to be pivotally supported. On the contrary, a shaft portion is provided on the support member side and connected. A member provided with a bearing at one end of the member may be used.

  As shown in FIGS. 8 to 12, the second support 3 </ b> B is attached to the outer peripheral surface of the lower pipe 70 of the stand main body 7 so as to be rotatable right and left about the central axis of the lower pipe 70. A support tool body 30, and one end part pivotally attached to the outer peripheral part 30a of the support tool body 30 so as to be pivotable in the left-right direction around an axis parallel to the axis of the lower pipe 70, and the other end part The end 2a of the leg 2 is composed of connecting members 32 and 32 each having a bearing 32a pivotably mounted in the vertical direction around an axis orthogonal to the axis of the lower pipe 70.
