When closing, the front truck 4 and the rear truck 5 are made to run at a constant speed along the front straight rail 10 and the rear straight rail 12 in the closing direction. In addition, when opening each movable roof 3 so that the arched side edges become V-shaped as shown in FIG. The front arc rail 1
1 in the opening direction, and when closing each movable roof 3 from the open state, move the front truck 4 to the front arc rail 11 with the rear truck 5 stopped at the movable roof closed position. run in the closing direction.

Further, as shown in FIGS. 17 to 19, front arcuate rails 1 extend in parallel to both left and right sides of the front part of the horizontally fixed roof 2 and to both left and right sides of the rear part of the horizontally fixed roof I12.
5 and the rear circular arc rail 16 are fixed, and intermediate straight rails 13 are fixed on both left and right sides of the intermediate part of the horizontally fixed roof 2, and the movable W root 3 is The rear end of the movable roof 3 is rotatably supported, the front end of the movable roof 3 is rotatably supported by the front truck 4 placed on the front arcuate rail 15, and the intermediate portion is further placed on the intermediate linear rail 13. A movable roof opening/closing device in which the intermediate portion of the movable roof 3 is supported by a subcarriage 14 has also been proposed.

When each movable roof 3 is opened so that the arched side edges are parallel to each other as shown in FIG.
When the rear bogie 5 is run at a constant speed in the opening direction along the front arc rail 15 and the rear arc rail 16 and each movable roof 3 is closed from the open state, the front bogie 5

9 to 13 show an embodiment of the second invention, in which a pair of semi-divided convex spherical plates are installed on both left and right sides of the upper part of the annular horizontally fixed roof 2 in the annular dome structure main body 1. Movable roofs 3 are arranged, the front end of each movable roof 3 is supported by a front truck 4 so as to be freely pivotable, the rear end of each movable roof 3 is rotatably supported by a rear truck 5, and the horizontal fixed roof 2 Front arcuate rails 8 centered on the center of rotation of the movable roof of the rear truck 5 placed in the movable roof closed position are fixed on both left and right sides of the front part of the horizontally fixed roof 2. The rear arc rail 9 centered on the movable roof rotation center of the front truck 4 placed in the roof closed position is fixed, and the front truck 4 is placed on the front arc rail 8, and the rear truck 5 is placed on the front arc rail 8. Although it is placed on the rear arcuate rail 9, the other configurations are the same as the embodiment of the first invention.

In the case of the embodiment of the second invention, as shown in FIG. 10, when the rear truck 5 attached to one movable roof 3A is stopped at the movable roof closed position, the front truck attached to the movable roof 3A is 4 in the opening direction, and the other movable roof 3
By moving the rear truck 5 attached to the movable roof 3B in the opening direction while the front truck 4 attached to the movable roof 3B is stopped at the movable roof closed position, each movable roof 3A, 3B is placed in an inclined parallel state. Can be opened.

Further, as shown in FIG. 11, when the front truck 4 attached to one movable roof 3A is stopped at the movable roof closed position,
The rear truck 5 attached to the movable roof 3A runs in the opening direction, and the rear truck 5 attached to the other movable roof 3B
When the movable roof 3 is stopped at the movable roof closed position, the movable roof 3
By running the front truck 4 attached to B in the opening direction, each movable roof 3A, 3B can be opened in a parallel state inclined in the opposite direction to that shown in FIG.

Further, as shown in FIG. 12, each movable roof 3 is expanded rearward by moving each rear bogie 5 in the opening direction with each front bogie 4 stopped at the movable roof closed position. It can be opened in a V-shape. Further, as shown in FIG. 13, each movable roof 3 is expanded forward by moving each front bogie 4 in the opening direction with each rear bogie 5 stopped at the movable roof closed position. It can be opened in a V-shape.

When implementing this invention, the front truck 4 and the rear truck 5
In order to fix the movable roof in the closed position, fixing bins are attached to the front trolley 4 and the rear trolley 5 so that they can be raised and lowered, and the fixing bins are inserted into the pin holes of the locking fittings fixed to the upper part of the horizontal fixed roof 2. It may be inserted and removed freely.

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects.

One movable Jl,! While the front truck 4A supporting the front end of the movable roof 3A is stopped at the movable roof closed position, the rear truck 5 supporting the rear end of the one movable roof 3A is run in the opening direction, By running the front truck 4B supporting the front part of the other movable roof 3B in the opening direction, each of the movable roofs 3A and 3B can be opened in a parallel state only by turning movement, and the rear truck 5 is stopped in the movable roof closed position, each front truck 4A,
4B in the opening direction, each movable roof 3
A, 3B can be opened in a v-shape, and especially in the case of this invention, the movable roof 3A.

The arched side edge in 3B is the circular arc rail 8A,
The movable roof 3A is arranged on a vertical plane orthogonal to the rear arc rail 9 and the movable roof 3A.

A lateral force that causes the arched side edges to expand due to the weight of the carriage 3B acts perpendicularly to the front arc rails 8A, 8B and the rear arc rail 5, and as a result, the lateral force causes the front bogies 4A, 4B and Since no load is applied to the rear bogie 5 in the running direction, the capacity of the drive device for running the bogie can be reduced, and the two opening/closing patterns of the movable roofs 3A and 3B can be changed to each movable roof 3A and 3B. This can be done only by turning the front truck 4A.

4B and rear bogie 5, since only one bogie is always running, the means for controlling the bogie operation is simpler than when two bogies are running at the same speed at the same time.Moreover, the horizontally fixed roof 2 Since it is not necessary to provide both a front arcuate rail and a front straight rail that are used interchangeably at the front of the roof, the movable roof opening/closing device can be manufactured economically.

In the case of the second invention, with any front truck 4 or any rear truck 5 stopped at the movable roof closed position, another rear truck 5 or another front truck 4 is made to travel in the opening direction. Therefore, the movable roof 3 can be placed in many different open states.
