Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a retractable roof that is suitable especially when the object to be roofed is a large space such as a stadium.

``Conventional technology'' Retractable roofs can satisfy the contradictory demands of providing a sense of openness, sunlight, and fresh air while also eliminating the harmful effects of rainy weather by υ1, and are already available in various configurations. provided or proposed.

For example, the retractable roof shown in FIGS. 5 and 6 includes a fixed roof 2 that covers the outfield stands of stadium I, two parallel moving roofs 3 and 4 that cover the upper part of the field, and a rotating roof 5 that covers the infield stands. It consists of, and when fully opened,
The parallel moving roofs 3 and 4 move toward the outfield stands and are drawn onto the fixed roof 2, and the swinging roof 5 rotates and is stored inside the fixed roof 2, thereby opening up the upper part of the ground. It has become so.

``Problems to be Solved by the Invention'' However, although the above-mentioned conventional retractable roof achieves its initial purpose in that the roof can be opened and closed, it has the following drawbacks.

That is, as shown in FIG. 6, the fixed roof 2 constituting the roof
, since the parallel moving roofs 3 and 4 and the rotating roof 5 are configured to divide the entire roof in parallel and perpendicular directions, (
1) Fixed roof 2, parallel moving roof 3, 4, when fully closed
(ii) The rotating roof 5 lacks stability and is difficult to obtain running stability when opening and closing; (ii) the roofs 3 and 4 move in parallel when fully opened;
(iii) When fully closed, the inner surface of each roof forms a step, giving a very oppressive feeling when looking up from inside; (1v) When fully opened, each roof is like an outfield stand. (V) In particular, when looking at the outfield from the infield stands, there is an extremely oppressive feeling as they are piled up upwards, so the relief effect of fully opening is not sufficient. There are various disadvantages such as not being able to enjoy the benefits of

Therefore, in view of the above circumstances, the present invention provides good stability of the fixed roof and movable roof when the roof is not fully open, reduces the retraction length of the movable roof, and furthermore provides a greater sense of freedom when the roof is fully opened. The purpose is to provide a retractable roof that can be opened and closed.

``Means for Solving the Problems'' The present invention is a retractable roof in which a dome roof is divided by planes passing through the roof's spherical center and configured to be freely openable and closable by a plurality of arch-shaped movable roofs. a pair of parallel support parts located on both sides of the roof and extending in parallel, and a circular support part located around the roof construction target and inscribed in the parallel support parts, and the movable roof is The main roof has both ends supported on a track provided on the support part and is movable along the track, and a pivot roof that has both ends supported on a track provided on the circular support part and is pivotable, and further includes: The present invention is characterized in that a fixed roof for storing the pivoting roof is provided on the movable side of the circular support section between the main roofs.

"Operation" From the fully closed state, move the main roof linearly along the trajectory of the parallel support part toward the outside of the fixed roof on the opening side,
By rotating the rotating roof along the trajectory of the circular support and storing it inside the fixed roof, the space above the roof installation target is fully opened. On the other hand, by moving the main roof to the moving side while in the opposite direction, and pulling out the swing roof from the fixed roof to the fixed position,
The area above the roof to be erected is completely closed.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 4 show an embodiment of the present invention, in which the retractable roof according to the present invention is applied to a large-scale space such as a baseball stadium.

In these figures, reference numeral 10 is a structure that supports the roof, and reference numeral 20 is a movable roof that constitutes a so-called dome-shaped roof when closed.

The structure 10 that supports the movable roof 20 includes a pair of parallel support parts l1 and l extending in parallel and facing each other on both sides of the stadium S, which has a substantially circular planar shape, on which the roof is to be constructed.
1, and the parallel support part 1 located around the stadium S.
1, I1 and circular support portions 12, I3 inscribed in the structure.

As shown in FIG. 2, a horizontal support 11a is provided above the parallel support parts 11 and 1l, and the support 11a includes:
The movable roof 20 is supported by its parallel support parts l1 and 1l.
A pair of straight tracks T, T are laid which guide the train in a straight line along the direction a. On the other hand, horizontal supports 12a and 13a are provided at the top of the circular support parts l2 and 13, and the support surfaces 1
2a and 13a are provided with arcuate tracks R that support a pivoting roof, which will be described later and which constitutes a part of the movable roof 20, so as to be horizontally pivotable along the circumference. A fixed roof 14 that covers an infield stand 15, which will be described later, is provided on one of the circular support parts 12 (on the opening side of a parallel moving roof 21, which will be described later).

The movable roof 20 is composed of a main roof 21 and a rotating roof 22, which together with the fixed roof I4 form a dome roof. The main roof 21 is supported at both ends 21a, 21a on linear tracks T, T provided in parallel support parts l1, 1l, and is movable in parallel along the tracks T. Swiveling roof 2
2 is rotatable with its peripheral edge 22a supported by a circular orbit R laid on the circular support parts 12 and 13.

Such fixed roof 14, main roof 21 and swing roof 2
2 has a basic structure in which each dome-shaped roof is divided by a plane passing through the roof's spherical center O, as shown by the dotted lines in Fig. It has a large circular shape with approximately the same radius of curvature.

In addition, the main roof 21 and the swing roof 22 are equipped with electric trolleys (not shown), and are capable of traveling in a self-propelled manner along their respective tracks.

When the retractable roof configured as described above is applied to a baseball stadium, the inner peripheral surface of the circular support part l2 on the open moving side of the main roof 2I will be used as the infield stand l5, and the circular support part on the opposite side will be used as the infield stand l5. By using the inner peripheral surface of l3 as the outfield stand 16, the advantages of existing roofless stadiums can be fully utilized in the open state. In other words, when looking toward the outfield from the infield stand 15, the front of the infield stand opens wide and provides a very liberating feeling.

The opening/closing operation and operation of the retractable roof configured in this manner will be described below.

FIG. 1 shows the dome roof in its idle state. In this state, the main roof 21 is located directly above the stadium S, and the swing roof 22 is in a fixed position on the opposite side of the fixed roof 14 along a circular orbit R. As a result, the space above the stadium S is covered with a dome roof.

On the other hand, in order to open the dome roof, the main roof 2l is moved away from directly above the stadium S along the straight track T, that is, to the outside of the fixed roof 14 along the straight track T, and then rotated. The roof 22 is pivoted in a direction opposite to the direction in which the roof closes, and is stored inside the fixed roof l4 as shown in FIG. As a result, the roof above the stadium S is fully open.

In addition, when closing the roof from the fully open state of the roof, it is sufficient to move the main roof 2l to a position above the stadium S, and then swing the swinging roof 22 to the normal position again to close it.

According to this embodiment, the following excellent effects can be achieved.

■ The fixed roof 14, main roof 21, and swing roof 22, which are formed by dividing the dome-shaped roof, have a basic structure in which the entire dome roof is divided by a plane passing through the center of the roof.
The cross section of the constituent roof has a large circular shape that is approximately the same as the radius of curvature of the entire roof, thereby ensuring sufficient stability between the main roof 2I, the swing roof 22, and the fixed roof 14 during periods of rest or when opening and closing. . This results in an economical cross section for each roof.

(2) Since the main roof 2l has sufficient stability and runs in the horizontal direction, it can be opened and closed more stably and smoothly using means such as a counterweight.

■ The main roof 21 covers almost the main part of Stadium S,
Because the length of the drawer when opening and closing can be shortened,
Economical installation space and structure of the substructure 10 are obtained.

■ Since each roof is divided by a plane that passes through the center of the dome, the inner shape of the dome roof when fully closed is a soft and stable curve, giving a feeling of oppression when looking up from inside. do not have. Also, there is no wasted space in the interior space.

■ When fully opened, each movable roof overlaps the fixed roof above and below and fits on the side of infield stand I5, so it does not create a feeling of pressure when looking up from inside and does not leave a gap in front when looking at outfield stand I6 from infield stand 15. The stadium can be opened to fully utilize the advantages of a traditional roofless stadium.

In addition, in this embodiment, the rotating roof 22 is configured to be stored inside the fixed roof 14, but the circular orbit R is
It is also possible to provide the swing roof 22 outside the fixed roof 14 and the main roof 21 so that the swing roof 22 is drawn between the fixed roof 14 and the main roof 21.

In this case, the main roof 2l and the swing roof 22 when fully closed
It is possible to reduce the gap between the joint end surfaces of the roof, and also to reduce the laminated thickness of each roof when the roof is fully opened.

"Effects of the Invention" As explained above, according to the retractable roof according to the present invention, the dome roof is divided by a plane passing through the roof's spherical center, and is configured to be freely openable and closable by the divided main roof body and the revolving roof. 100% of the large-scale space above the stadium can be opened and closed using a simple method in which the main roof and the swing roof, which are movable roofs, travel and are pulled in above and below the fixed roof. Moreover, since each roof is divided by a plane passing through the dome's spherical center, the fixed roof and movable roof are particularly stable when fully closed or opened, and each roof has an economical cross section. is obtained. Furthermore, the main roof that covers the main part above the stadium can be shortened in length, resulting in an economical lower structure.

Furthermore, by installing the fixed roof on the circular support on the opening side of the main roof, when the roof is fully opened, a vast space opens out to the front on the opposite side, providing a very open feeling outdoors. in this way,
The conflicting demands of a retractable roof can be met extremely effectively.
