For example, the roof may be made into a flat plate and foldable, and the roof can be opened and closed by folding or expanding it, or as shown in Figure 5, the roof may be constructed into a fixed roof part l and a movable roof part. 2, and the movable roof part 2 is bowed onto (inside) the fixed roof part 1, thereby opening a part of the upper part of the roof construction target area S.

In addition, as shown in FIGS. 6 and 7, by rotating at least two fan-shaped roof units 3 about the support 4 that is the center of the fan shape, the roof can be extended to the roof construction target S. can be freely erected and removed, the roof units 3 each share the same center of rotation, and there is a wall in the vicinity of the fan-shaped arc formed by the roof unit 3 and in the vicinity of the center of rotation, respectively. A first support leg 5 and a second support leg 6 are provided for supporting the roof unit 3, and the first support leg 5 and the second support leg 6 each move along a track 7.8. A structure including a slide mechanism is also known.

``Problems to be Solved by the Invention'' By the way, although these conventional retractable roofs have achieved their initial purpose in that the roof can be opened and closed, they also have the following drawbacks.

That is, in the case of the former folding type, the operating mechanism is complicated, and the form is limited to a plate-like flat structure, which lacks design when viewed as a whole building. Furthermore, in the case of FIG. 5, the fixed roof part l supports the movable roof part 2, so not only is it necessary to structurally strengthen the fixed roof part 1, but also the movable roof part 2 is also cantilevered. This requires structural reinforcement, which increases the cost.

On the other hand, in the case of the retractable roof shown in FIGS. 6 and 7, there is an advantage that the roof can be erected to and removed from the roof object S arbitrarily and easily, but the pillar 4 is located at the center of rotation of the roof unit 3. As a result, this becomes a major constraint when designing the roof construction object S on which this roof will be constructed.Moreover, in a type in which the roof unit 3 is supported at the center of rotation, stress concentration on the center axis of rotation and Since there are problems such as stress concentration in the center of the roof unit 3 itself, it is difficult to achieve economical design from the viewpoint of structural and weight reduction, and it is difficult to achieve 100% opening/closing of the roof. However, there are various problems that need to be improved, such as the fact that the side wall portion must surround or move away from the roof construction object S at the same time as the roof unit 3, which increases the cost accordingly.

Therefore, in the present invention, a large-scale space above a stadium etc. can be covered 100% of the time by using a simple method in which multiple roofs move together in a straight line, and three roofs move in a rotating manner.
It can be opened and closed, and by making all the roofs into an arch shape with support at both ends, it is an economical design compared to arch shapes with cantilever beams or pivot support, reducing weight and cost. The present invention aims to provide a retractable roof that is both visually appealing and extremely innovative in terms of design.

"Effects of the Invention" As explained above, in the retractable roof according to the present invention, the dome-shaped roof is constructed of four arch-shaped movable roofs that overlap vertically and horizontally to freely open and close. A pair of parallel support parts located on both sides of the roof construction target and extending in parallel, and a circular support part located around the roof construction target and inscribed in the above-mentioned parallel support part, The movable roof includes an upper large roof that is horizontally movable by being supported at both ends on tracks provided in the parallel support section, a lower large roof that is stored inside the upper large roof, and the upper large roof and the lower large roof. The lower large roof and the two small roofs have both ends connected to tracks provided in the circular support part. Because it is supported and has a pivotable configuration,
Three rotating roofs forming part of a dome-shaped roof are housed inside one large upper roof that runs horizontally and linearly along a straight track provided on a parallel support. With a simple method in which all roofs move horizontally and linearly as one, it is possible to open and close 100% of the large space above the stadium, which reduces the amount of wind inside when the roof is open. The upper large roof, which also constitutes a moving roof, can reduce the effect of turbulence on
Since the lower large roof and the two small roofs are all arch-shaped with support at both ends, the design is more economical than cantilever or pivot-supported arch shapes, and the weight is reduced accordingly. In addition, the four roofs that make up the dome-shaped roof can be moved in parallel, or some of them can be moved in a circular motion, which improves the design. It also becomes extremely innovative, and produces an excellent effect that has never been seen before, such as creating an effect that gives the viewer a sense of unexpected functionality.

In addition, especially according to the present invention, two small roofs are stored side by side between the upper and lower large roofs, so even though there are four roofs, the roof as a whole has three roofs. It has a layered structure, which has the effect of making the roof thinner.
