This relates to retractable roofs. For outdoor sports such as baseball and bicycle racing, the stadium area is large and pillars cannot be erected, and it is desirable to be held under the blue sky on sunny days, so stadiums without roofs are constructed with buildings such as bleachers surrounding the stadium. It has been carried out in However, canceling the competition due to rain cannot dampen the excitement of the spectators, and will result in huge business losses and wasted preparations on the part of the organizers. The present invention addresses these problems and provides a roof that can be opened and closed on large buildings, which is desirable to be open on sunny days and requires a roof on rainy days.

A grooved guide rail 3 made of C-shaped steel or the like is installed along the edge of the open upper part of the wall 2, and an arcuate curved guide rail 3 is installed along the edge of the open upper part of the wall 2. A beam body 4 is installed across the bridge. On the lower side of the beam body 4, there is a housing part 6 that accommodates a membrane body 5 that opens and closes in a fan shape.
is provided, and the upper part of this storage section 6 is connected to the grooved guide rail 3. The membrane body 5 is configured such that an opening/closing end 51 opens and closes in a fan shape with a main part 50 as the center, and the opening/closing end 51 has a trochanter that fits into the guide rail 3 at intervals and slides on the drive mechanism 11. The main part 50 is provided with a hanging hook part 8. One end of a tension rope 10 hung on a guide wheel 9 such as a pulley provided at the center of the beam body 4 is fastened to this hook portion 8, and each end of the rope 10 is connected to a pulley 9 to drive a motor or the like.

い発明である。 The present invention has the above-mentioned structure, and when covering the upper open part of a room surrounded by the outer shell of a large building with an open upper part, the storage part 6 is stored in the storage part 6 provided on the lower side of the beam body 4 installed in the open part. The membrane body 5 is lifted by winding the rope 10 connected to the drive mechanism 12 and pulling it from the main part 50 side.The open/closed end of the membrane body 5 comes to the position of the guide rail 3, and the hanging/disengaging rail 31 engages with the guide rail 3. Then, the winding is stopped, and when the lead rope 16, which is connected to the guide member 7 such as a trochanter placed at the opening/closing end of the membrane body 5 and stretched along the guide rail 3, is wound by the winding winch, When it is pulled, the opening/closing end 51 opens along the guide rail 3 and the membrane body 5 expands around the main part 50, so that the main part 51 is lifted upward and pulled to close and cover the upper open part. In addition, in order to open the upper part on a sunny day, the above operation is completely reversed, that is, the joint part is separated and the tension on the main part 50 is released while the lead rope 16 is released.
is wound in the opposite direction, and the opening/closing end 51 of the membrane body 5 is slid along the guide rail 3 to close and close it, and when it is collected on the hanging rail 31, it is pulled into the storage part 6 by the retracting guide rail 32 and the motor 14. The closed membrane body 5 is pulled down and stored. Note that, of course, it is not necessary to store the membrane body depending on the case. Since the present invention is constructed as described above, it is possible to easily open and close the roof of a large building by driving a winding winch and a tension winch as seen in a cable car. Since it is completely retracted, it does not spoil the aesthetic appearance.
Since the operation is almost automatic, it is possible to cope with rain during the competition, and the invention has a wide range of applications.
