Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a foldable stand for a keyboard musical instrument that is attached to the lower surface of the keyboard musical instrument.

[0002]

[Prior art]

 Traditionally, keyboard instruments and their supporting stands are sold separately and are assembled by the user. FIG. 7 shows a connecting metal part of a conventional folding stand, and FIG. 8 shows a state in which the conventional folding stand is folded. In the conventional folding stand for keyboard musical instruments, the left and right legs A, A are fastened to the back surface of the keyboard musical instrument with screws, and the connecting rods B, B whose one end is pivotally attached to both legs A, A are the connecting members C. The connection metal fitting C is fastened with a screw to the back surface of the keyboard musical instrument.

[0003]

[Problems to be solved by the device]

 Conventionally, the above-mentioned stand is folded so that the left and right legs A and A are overlapped with each other, and is stored in a packaging box different from the keyboard instrument and stored in a warehouse or transported. Conventionally, since the connecting rods B, B project from the legs A, A when folded, as shown in FIG. 8, a long packaging box is used, and accordingly, the packaging box price, storage cost, transportation cost, etc. Has the drawback of being expensive. Therefore, the present invention aims to provide a foldable stand for a keyboard instrument that can reduce the packaging size when folded.

[0004]

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the folding stand for keyboard musical instruments according to the present invention has a hole for inserting a tightening screw in the vertical direction at the center of the upper lateral rod of the left and right legs of a substantially inverted U shape. Brackets are fixed to the side rods, and the brackets are attached to each of the brackets. The other end of the connecting rod is pivotally attached to the outer surface of the vertical piece of the formed connecting metal fitting, and the horizontal piece extending inward of the connecting metal is provided with a through hole for a tightening screw, which is provided on the lateral rod of the leg. Tightening screws are inserted from below into the insertion hole and the insertion hole provided in the connecting metal fitting, and the screws are screwed into the three female screws provided on the back surface of the keyboard musical instrument.

Generally, when the length of the connecting rod is equal to or shorter than the height of the bracket, the folding size is minimized.

[0006]

[Action]

 When the stand is attached to the back of the keyboard instrument, the left and right legs are distant from each other, so that the horizontal piece of the connecting bracket is at the same height as the upper surface of the horizontal rod. When folding, the left and right legs are further retracted, and the connecting metal fitting is lowered to the height of the bracket. When the bracket is further lowered, both legs come close to each other, and the connecting rods are folded and folded. If the length of the connecting rod is designed to be the same as or shorter than the height of the bracket, the tip of the connecting rod will not protrude, so the length of the package can be short.

[0007]

【Example】

Examples will be described with reference to the drawings. Reference numeral 1 denotes a leg body formed by two leg rods 2, 3 and a horizontal rod 4 in a substantially inverted U-shape. The two leg bodies 1, 1 form a pair and are fastened to the central portion of the horizontal rod 4. An insertion hole 6 through which the attached screw 5 passes is open upward and downward. A bracket 7 is fixed to the leg rod 2 on one side of both legs 1, 1, and one end of a connecting rod 8 having a length substantially equal to the dimension from the lower end of the leg rod 2 to the bracket 7 is attached to the bracket 7 by a pivot pin 9. It is pivotally attached. 10 is a small piece of metal bent at a right angle The other end of the connecting rod 8 is pivotally attached to the outer surface of the connecting rod 8 by a pivot pin 13, and a horizontal piece 11 extending inward of the connecting fitting 10 has an insertion hole 15 through which a tightening screw 14 passes.

On the back surface of the keyboard musical instrument 16, female screws (not shown) are provided at a total of three places, that is, two left and right holes 17 and 17 at the center of the radiation and one hole 18 at the center of the length. Fix the legs 1 and 1 by screwing the tightening screw 5 passed through the insertion hole 6 into the female thread of the hole 17, and screwing the tightening screw 14 passed through the insertion hole 15 into the female screw of the hole 18. .

[0009]

[Effect of device]

 You can fold the legs by lowering the connecting metal fittings, and when assembling, you can raise the connecting metal fittings to the height of the legs, so you can easily assemble them as before, and fold them more than before. The smaller size reduces packaging, storage and transportation costs.
