(b) Prior Art and its Problems Conventionally, stage units constituting auxiliary stages or temporary stages in halls, gymnasiums, etc. have been provided with foldable legs on a flat top plate.

However, this stage unit occupies a large volume even after being folded, so it requires a large storage space, and since each unit is large, it is difficult to transport it from one venue to another. Requires large transportation space.

Furthermore, since the top plate is square or rectangular, it is not possible to construct a trapezoidal deformed stage, for example.

In addition, since conventional stage units are simply arranged side by side to form a stage, they have the problem of being easily separated and unstable.

(c) Means for solving the problem In view of the above-mentioned problem, the stage unit according to the present invention connects three side panels so that they can be folded in one direction, and has a total width dimension of the left and right side panels. A frame body whose width is equal to or less than the width of the side plate located in the center, and in which at least the side plates located on the left and right sides are provided with connection member attachment parts such as connection through holes or connection notches, and assembly of this frame body. The top plate has a planar shape that sometimes covers the opening formed by the side plate, and has a positioning protrusion on the lower surface that abuts the inner edge of the opening.

(d) Actions and Effects Therefore, according to the stage unit according to the present invention, since the frame body has a planar triangular shape, a modified stage can be easily constructed by combining it with other units, etc. .

In addition, the top plate can be removed and the frame can be folded flat, so it does not require a large space for storage or transportation.

Moreover, the stage unit according to the present invention can be connected and integrated with other stage units using the connecting member through the connecting member attachment part such as the connecting through hole provided in the side plate, so it is difficult to separate and has good stability. There is an effect.

The width dimension of 3 is approximately the same as the width dimension of the side plate 3 constituting the main unit 1. The width of the side plate 14 is equal to the width of the side plate 12 minus the width of the side plate 13.

Therefore, even if the side plates 13 and 14 are folded,
The side plates 13 and 14 do not overlap on the side plate 12 and can be folded compactly (7th
figure).

Note that the width dimension of the side plate 12 may be larger than the total width dimension of the side plate 13 and the side plate 14.

In addition, the side plate 13 has a connection through hole 13a and a transportation through hole 13b, and the side plate
4 is also provided with a connecting through hole (not shown).

Furthermore, although the side plate 12 is also provided with the connection through-hole 12a and the transportation through-hole 12b, the connection through-hole 12a may not be provided.

The top plate 15 has a planar shape obtained by diagonally dividing the top plate 4 constituting the main unit 1, and has an inner edge of an opening 11a formed when the side plates 12, 13, 14 are opened and assembled on the lower surface. An annular positioning protrusion 16 is provided which abuts on and regulates the position. The top plate 15 has a soundproofing elastic body 17 (for example, a rubber plate, etc.) that comes into contact with the upper end surface of the discontinuous frame 11 adhered to the outer circumferential portion of the lower surface thereof, and a central portion of the lower surface thereof. In order to prevent the occurrence of stepping sounds, etc., a foam material 18 (for example, styrofoam, etc.) is placed inside the positioning protrusion 16.
