Description

[Detailed description of the invention] Various types of portable musical instrument stands have been known in the past, but in order to make them smaller during transportation, the parts must be taken apart, which makes them easy to lose and difficult to disassemble and reassemble. Moreover, since the front length of the instrument holder is constant, it is difficult to use the instrument holder stably with instruments having different front lengths.

The object of the present invention is to provide a portable musical instrument stand which does not have such drawbacks and whose instrument holder can be tilted and horizontally. are each pivotally connected at the lower bent portion 3 by a pivot shaft 7, a plurality of locking portions 6 are provided at the intermediate portions of the left and right columns 1, and a base 4 is attached to the lower end portion of each of the columns 1. One end of each connecting member 5 is pivotally connected to the upper part of each of the two connecting members 5, and the intermediate portions of the two connecting members 5 are pivotally connected in a cross-shaped manner, and the notch 13 of each other end is connected to one of the locking parts 6 of each of the pillars. A plurality of concave grooves 8 are formed in an arc shape centered on the pivot shaft 7 in either one of the pillars 1 or the lower bent portion 3, and the other is provided with a plurality of concave grooves 8 in an arc shape centered on the pivot shaft 7. Each protrusion 9 is formed to fit into the groove 8.

1 to 6 show an embodiment of the invention in use.

In the drawing, the left and right columns 1 are made of columnar material with a U-shaped cross section, and a nut 1 is attached to the inner surface of each upper end.
0, and by screwing screws, which are the pivot shafts 7, into the nuts 10 through holes provided in the lower bent portion 3 and the support 1, a musical instrument holder 2 is attached to the side surface of each upper end. are pivotally mounted, and a base 4 is mounted on the side of each lower end.
is connected by screwing the screw 12 into the screw hole 11 of the support column 1 through the hole, and one end of each of the two connecting members 5 which are pivotally connected in a cross-shaped manner is pivotally connected to the upper side of each middle part. A plurality of threaded holes for screws 14 that are screwed together through the notches 13 at each other end of the connecting member 5 are formed on the lower side of each intermediate portion, and the threaded holes are connected to the locking portions at the other end of the connecting member 5. And so. In addition, a plurality of recessed holes 8 are formed on the side surfaces of the upper end portions of the left and right pillars 1 on an arc centered on the screw serving as the pivot shaft 7, and the lower bent portion 3 of the musical instrument holder 2 is provided with a plurality of recessed holes 8. A protrusion 9 that fits into the recessed hole 8 is formed.
The horizontal part of the musical instrument holder 2 has a hole 1 into which a rubber foot 16 provided on the bottom of the musical instrument 15 is fitted, as shown in the fourth figure.
7 was formed.

Thus, as shown in the first diagram, if the instrument holder 2 is held horizontally and the screw 7 is screwed in, the protrusion 9 will fit into the central concave hole 8.
, the instrument holder 2 is fixed in a horizontal position, with the base 4 perpendicular to the support 1 and the screw 1
2 is screwed in, the protrusion provided on one side fits into the recess 18 provided on the other side and is fixed in that position, as in the case of the musical instrument holder 2, and the instrument is set in use.

When playing while sitting, it is best to keep the instrument holder 2 horizontal, but when playing standing, it is better to tilt the front side upwards, so loosen the screw 7 and move the protrusion 9 to the front of the support Fit it into the recessed hole 8 and tighten the screw 7.

The front length of the instrument is the left and right instrument holders 2 as shown in the first diagram.
When the distance is longer than the distance between the cutouts 13 and 13 at the lower ends of the connecting members 5 and 5, as shown by the broken line in FIG.
are aligned with the upper screw holes 6, 6, and the screws 14, 14 are screwed into the screw holes 6, 6 respectively to fix them and widen the distance. If one or both of the musical instrument holders 2 are inverted and fixed to the support 1 as shown in FIG. 6, the types of musical instruments that can be used will increase.

When transporting the musical instrument stand, loosen the screws 7 and rotate the musical instrument holders 2, 2 so that they are aligned with the supports 1, 1 as shown in Figure 7, and fix them by tightening the screws again. Do the same for bases 4 and 4. Further, the lower ends of the connecting members 5, 5 are removed from the screws 14 by loosening the screws 14, and both supports 1, 1 are brought together. In this way, the instrument stand becomes rod-shaped. In this way, according to the present invention, the instrument holders 2, 2 are pivotally attached to the upper ends of the left and right columns 1, 1, the bases 3, 3 are fixedly and rotatably attached to the lower ends, and the middle parts are attached to the bases 3, 3, respectively. Since a plurality of engaging portions are provided to pivotally connect one end of each of the two connecting members 5, 5 which are pivotally connected in a cross-shaped manner and to engage with each other end, multiple types of musical instruments of different sizes are provided. In addition, it can be miniaturized without having to be disassembled into individual parts during transportation. In addition, since a plurality of recessed holes 8 are formed in one of the instrument holders 2, 2 and the pillars 1, 1, and a protrusion 9 that fits into the recessed hole 8 is formed in the other, the instrument holders 2, 2 can be held horizontally. It has the effect of increasing the degree of freedom in playing posture, as it can be held in a tilted position or in an inclined position.
