[Prior Art] A roof covering an upper part of a stadium or the like is proposed so that the stadium, an outdoor hall, or the like can be used even in bad weather.

However, in fine weather, a roof that can be opened and closed has been desired for reasons such as spoiling the taste of competitions or the like that should be performed outdoors.

A fan-shaped openable roof has been proposed as one of those that can meet such demands.

The fan-shaped openable and closable roof has a fan shape in plan view as shown in FIG. 6 (a) and FIG. 6 (b), and has a plurality of swivel roofs. Is designed to open and close the roof by turning around the main point.

[Problems to be Solved by the Invention] However, in the conventional fan-shaped opening / closing roof, a main portion for supporting the swivel roof constituting the fan-shaped opening / closing roof is shown in FIG. 6 (a) and FIG. As shown in Fig.), Since the shaft is supported by one or two points by the pin structure, a large load is applied to the shaft supporting part, and the structure of the shaft supporting part is made large in order to bear the load. There was a problem that it had to be.

The present invention has been made in view of such problems of the prior art, and an object of the present invention is to make a structure for supporting a fan-shaped opening / closing roof smaller than that of the prior art. The purpose is to provide a fan-shaped openable roof that can be opened.

[Means for Solving the Problem] The gist of the present invention is a fan-shaped openable roof in which a flat fan-shaped roof is configured to be freely opened and closed by a plurality of arch-shaped swiveling roofs that are vertically stacked. An outer raceway which is located around the circumference and extends in an arc shape, and an inner raceway which is located near the center of rotation of the swivel roof and has a smaller radius of curvature than the outer raceway. There exists a fan-shaped openable roof in which the side is supported by the outer track and the inner end is supported by the inner track so as to be turnable.

[Operation] The inner track supports the inner edge of the swing roof. Therefore, according to the present invention, the pin structure for supporting the swivel roof can be eliminated.

The inner track allows the swivel roof to be supported by a plurality of points instead of a single point. Therefore, in the case of supporting the swivel roof at a plurality of points, it is possible to make the supporting structure of the swivel roof smaller than in the prior art. This is because it is possible to distribute the load applied to the portion where the lid is supported and the roof is supported to a plurality of points.

Also, since the bearing structure can be made smaller,
The portion where the swivel roofs overlap each other can be reduced.
