2. Description of the Related Art Conventionally, various musical instrument stands for supporting portable musical instruments such as a keyboard and a conga have been known. As these musical instrument stands that can be changed in width with a simple configuration, those having an “X structure” in which support frames are crossed in an X shape are often used. Such a stand of the X structure has a structure in which a musical instrument is installed by opening and closing a lower leg and a upper pedestal with a center of a plate or a bar as a fulcrum. However, in the stand of this structure, the width of the pedestal can be adjusted to the width of the musical instrument by adjusting the degree of opening and closing of the legs and the pedestal, but the height of the stand changes accordingly. . That is, in the case of a wide instrument, the height of the stand is low, while in the case of a narrow instrument, the height of the stand is high.

A structure in which the height of the stand is constant or adjustable is described in, for example, Japanese Patent Publication No. 2610008 and Japanese Utility Model Laid-Open Publication No. 7-34488.
Also, the structure that allows the width of the stand to be adjusted is, for example,
It is described in Japanese Utility Model Registration No. 2503592.

[0004]

However, the prior art stand described in the above publication has a large number of parts, and its structure is complicated. Therefore, it takes a long time to assemble and adjust the stand, and it is necessary to carefully check parts even during storage.

The present invention has been made in view of the above points, and allows the width of a stand to be adjusted without changing the height of the stand for musical instruments having different widths. It is an object of the present invention to provide a musical instrument stand that can be adjusted.

[0006]

In order to achieve the above-mentioned object, the present invention comprises at least three legs and a leg support frame on which the legs are mounted, and each leg support frame includes a leg support frame. Each leg is inclined and held so that the interval between them becomes narrower upward, and the position of each leg can be changed along the inclination direction.

According to this configuration, the width (interval) of the upper ends of the plurality of legs to be assembled is made by moving the leg support frame holding the plurality of inclined legs up and down along the inclination of each leg.
The width of the stand can be made wider or narrower, so that the height of the stand can be adjusted to the width that matches the instrument, while keeping the height of the stand constant at a predetermined height for instruments with different widths. . Moreover, according to this configuration, since the structure can be simple, the width can be easily adjusted and the possibility of breakage is small.

This musical instrument stand 1 is composed of four legs 4 made of a cylindrical material which is held at an angle at a fixed angle, and an X-shaped leg support frame 9 as viewed from above where these legs 4 are mounted. It is mainly composed. At each end of the X-shaped leg support frame 9, a leg attachment portion 11 having an inclined cylindrical opening 10 slightly larger than the thickness of the leg is provided. A screw hole 12 is provided at substantially the center of the outermost side surface of each leg attachment portion 11. A plurality of screw receiving holes 14 are provided at substantially equal intervals in each leg 4 corresponding to the screw holes 12. A pedestal 4 for receiving a musical instrument at the upper end and the lower end of each leg 4 respectively.

When assembling the stand 1, each leg 4
Opening 1 of leg attachment portion 11 provided at the tip of leg support frame 9
The position is adjusted by moving up and down along the slope as indicated by arrow A so that the distance between the pedestals 4a at the upper ends of the four legs matches the width of the stand. The four legs 4 are screwed into the screw receiving holes 14 via the screw holes 12 at the positions of the screw receiving holes 14 having the same height, so that the four legs 4 are fixed to the leg supporting frame. 9 and fix it with screws. When all the legs 4 are held by the leg support frames 9 in this manner, as shown in FIG. 1, the intervals between the legs 4 are narrowed upward, and the legs 4 are fixed in an inclined state. In this state, the distance between the upper ends of the legs corresponds to the width of the stand as described with reference to FIG.

In the assembly of the leg support frame 9 and the legs 4 described above, if the keyboard 2 is large, the leg support frame 9 is arranged above as shown in FIG.
