Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an openable / closable roof capable of freely erection / removing a roof such as an event site.

"Prior art" The retractable roof can meet the contradictory requirements such as outdoor open feeling, sunlight, fresh air, etc., and can eliminate the adverse effects of rainy weather, and already have various configurations. Are provided or proposed.

For example, the roof is removed from the target roof erection site by simply moving it laterally from the target roof erection target site, or the roof is composed of a fixed roof part and a plurality of movable roof parts. By releasing the part above the fixed roof part (inside) to release the upper part of the roof construction target, or by making it a flat plate of the roof and making it foldable, by folding and unfolding it There are things such as opening and closing above the target construction site.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional retractable roof, although the intended purpose as described above is certainly achieved, each has the following drawbacks.

That is, in the case where the roof is simply moved in parallel to be removed from the erection target site, a valuable space is sacrificed because an escape portion for the roof to be removed is required. Further, in the case where the movable roof portion is pulled over (inside) the fixed roof portion, the presence of the fixed roof portion cannot increase the opening ratio of the roof to a large extent, so that the merit of the retractable roof cannot be fully utilized. Further, in the case of a foldable type, although a retreating space can be eliminated, it is necessary to newly provide a storage part and the like, and the operating mechanism becomes complicated.

[Means for Solving the Problems] Therefore, in the present invention, in the closed state, a roof formed in a planar shape as a whole is divided into left and right parts, one of which is a moving roof part and the other of which is a fixed roof part. The roof portion is configured to be rotatable around the circular center, and is formed in a shape that can be superimposed above or below the fixed roof portion as the movable roof portion is rotated. Of each of the roof portions, the central portion side including the circular center is divided into movable roof units, and the movable roof units are configured to be movable in the radial direction of the circular shape to form a retractable roof. By doing so, the problem is solved.
