Description

TECHNICAL FIELD The present invention relates to a retractable roof suitable for a case where a roof is to be erected, particularly in a large-scale space such as a stadium.

"Conventional technology" Opening and closing roofs can meet the conflicting requirements of being able to obtain the open feeling of the outdoors, sunlight, fresh air, etc., and eliminate the adverse effects of rainy weather. Things have been provided or proposed.

For example, the retractable roof shown in FIGS. 5 and 6 includes a fixed roof 2 that covers the outfield stand of the stadium 1, two parallel moving roofs 3 and 4 that covers above the ground, and a revolving roof 5 that covers the infield stand. It consists of and, and when fully opened,
The parallel moving roofs 3 and 4 travel to the side of the outfield stand and are drawn onto the fixed roof 2, and the swiveling roof 5 swivels and is stored inside the fixed roof 2, thereby opening 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 can achieve the initial purpose in that the roof can be opened and closed, it has the following drawbacks.

That is, as shown in FIG. 6, since the fixed roof 2, the parallel moving roofs 3 and 4, and the revolving roof 5 that form the roof are configured in a form in which the entire roof is divided into parallel and vertical directions,
(I) Fixed roof 2, translation roof 3 when fully closed,
4. The stability of the swivel roof 5 is lacking, and it is difficult to obtain running stability when opening and closing. (Ii) The parallel moving roof 3 when fully opened.
4) The pull-in / pull-out length is large, (iii) When the roof is fully closed, the inner surface of each roof forms a step, which gives a very oppressive feeling when looking up from the inside. (Iv) When the roof is fully opened, each roof is outfield. Since it is stacked above the stand, you can feel a sense of pressure from the inside of the roof, (v) In particular,
Looking at the outfield from the infield stand is very oppressive, and there are various drawbacks such as not being able to fully enjoy the release effect due to full opening.

Therefore, in the present invention, in view of the above circumstances, the stability of the fixed roof and the moving roof at the time of fully closing is good, the retracting length of the moving roof can be made small, and further, a greater feeling of release when the roof is fully opened can be obtained. The purpose is to provide a retractable roof.

"Means for Solving the Problem" In the present invention, a dome roof is roughly divided into three curved plates each having an arched side edge in plan view by two planes passing through the roof sphere and sandwiching the top of the dome roof. And a pair of parallel supporting portions extending in parallel at both ends of the roof erection target and a periphery of the roof erection target. And a circular support portion inscribed in the parallel support portion, and the two movable roofs are supported at both ends on a pair of linear tracks provided on the parallel support portion, and It is composed of one main roof that can move in parallel along the top of the dome roof, and a revolving roof whose both ends are supported by a track provided on the circular support, and the revolving roof can further rotate. Opening of the main roof The fixed roof for housing the swivel roof is located on the moving side.

[Operation] From the fully closed state, the main roof is linearly moved toward the outside of the fixed roof on the open moving side along the track of the parallel support, and the swivel roof is swung along the track of the circular support. By storing inside the fixed roof, the upper space of the roof installation target is fully opened. On the other hand, by moving the main roof to the opposite closing movement side and pulling out the revolving roof from the fixed roof to a fixed position, the upper part of the roof erection target is fully closed.

[Examples] Examples of the present invention will be described below 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 drawings, reference numeral 10 is a structure that supports the roof, and reference numeral 20 is a moving roof that constitutes a so-called dome-shaped roof in a closed state.

The structure 10 that supports the movable roof 20 includes a pair of parallel support portions 11 and 11 that extend parallel to each other on opposite sides of a stadium S that is a roof installation target and that has a substantially circular shape in a plane.
The circular support parts 12 and 13 located around the stadium S and inscribed in the parallel support parts 11 and 11 are provided.

As shown in FIG. 2, a horizontal support surface 11a is provided on top of the parallel support parts 11 and 11, and a movable roof is provided on the support surface 11a.
The main roof, which will be described later, that forms a part of the
A pair of linear tracks T, T that linearly guide along the support surface 11a of 11 are laid. On the other hand, horizontal support surfaces 12a and 13a are provided above the circular support parts 12 and 13, respectively.
An arcuate track R is installed on 12a and 13a to support a later-described swivel roof that forms a part of the movable roof 20 so as to be horizontally swivel along a circumference. A fixed roof 14 that covers an infield stand 15, which will be described later, is provided on one of the circular support portions 12 (on the side where the parallel moving roof 21 that is described below is open and moving).

The moving roof 20 is composed of a main roof 21 and a swiveling roof 22 that form a dome roof together with the fixed roof 14. The main roof 21 has both ends 21a, 21a supported on a pair of linear trajectories T, T provided on the parallel supporting portions 11, 11 so that the main roof 21 can move in parallel along the pair of linear trajectories T, T. The swivel roof 22 is swivelable by supporting a peripheral edge 22a on a circular orbit R laid on the circular support portions 12 and 13.

Such fixed roof 14, main roof 21 and swivel roof 22
As shown by the dotted line in FIG. 2, the dome-shaped roof is formed into an arch-shaped curved plate having curved side edges in plan view by two planes that pass through the roof spherical center O and sandwich the top of the dome-shaped roof. It is divided. Here, the main roof 21 is located in the center so as to include the top of this dome-shaped roof, whereby the cross-sectional shape of each roof 14, 21, 22 is made into a great circle shape which is approximately equal to the radius of curvature of the entire roof. There is.

It should be noted that the main roof 21 and the swing roof 22 are provided with electric carts (not shown), and are capable of traveling on their own tracks in a self-propelled manner.

When the retractable roof configured as described above is applied to a baseball stadium, the inner peripheral surface of the circular support portion 12 on the open movement side of the main roof 21 is defined as an infield stand 15, and the inside of the circular support portion 13 on the opposite side. By setting the outer surface as the outfield stand 16, the advantages of the existing uncovered stadium can be fully exhibited in the open state. That is, when the infield stand 15 is viewed in the outfield direction, the front of the infield stand 15 is opened wide and a great sense of liberation can be enjoyed.

The opening / closing operation and action of the thus constructed openable roof will be described below.

FIG. 1 shows the closed state of the dome roof. In this state, the main roof 21 is located directly above the stadium S, and the revolving roof 22 is in a fixed position on the opposite side of the fixed roof 14 along the circular orbit R. The vehicle moves and moves, so that 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 21 is moved along the straight track T in a direction away from directly above the stadium S, that is, along the straight track T to the outside of the fixed roof 14 to make a turn. The roof 22 is swung in a direction opposite to the direction in which the roof is closed, and as shown in FIG.
To store inside. As a result, the roof above the stadium S is fully opened.

In order to close the roof from the fully opened state, the main roof 21 may be moved to a position above the stadium S, and the revolving roof 22 may be swung to a fixed position again to be closed.

According to this embodiment, the following excellent effects are obtained.

Fixed roof 14, main roof 21, which is a domed roof divided
Since the swivel roof 22 has a basic structure in which the entire dome roof is divided by a plane that passes through the roof spherical center, the cross section of each constituent roof has a great circle shape that is approximately the same as the radius of curvature of the entire roof, so that when fully closed. Or the main roof when opening and closing 21
In addition, the stability between the swiveling roof 22 and the fixed roof 14 is sufficiently ensured. This provides an economical cross section for each roof.

Since the main roof 21 has sufficient stability and the traveling direction is horizontal, it is possible to open and close more stably and smoothly by using a means such as a counterweight. Furthermore, since there is only one main roof 21, it is only necessary to provide a pair of tracks T, T on the parallel support parts 11, 11 to simplify the structure, reduce the manufacturing cost, and perform inspection and maintenance. Can also have the effect of becoming easier.

The main roof 21 covers almost the main part of the stadium S, and the length of pull-in / pull-out when opening and closing the stadium S can be shortened, so that an economical installation space and structure of the lower structure 10 can be obtained.

Each roof is an arch-shaped curved plate with curved side edges in plan view, which is obtained by dividing the entire dome roof with a plane that passes through the roof sphere, so the inner shape of the dome roof is soft and stable when fully closed. It is curved and does not give a feeling of pressure when looking up from the inside. Further, since a waste space is further provided in the inner space and the entire dome roof looks like a substantially curved surface from the outside, it is possible to provide excellent scenery.

When fully opened, the moving roofs overlap the top and bottom of the fixed roof and fit on the side of the infield stand 15, so there is no sense of pressure when looking up from the inside.
When you look at, you can open the front openly, and you can fully utilize the advantages of the conventional roofless stadium.

Although the swivel roof 22 is stored inside the fixed roof 14 in this embodiment, the circular orbit R is provided outside the fixed roof 14 and the swivel roof 22 is drawn between the fixed roof 14 and the main roof 21. It can also be configured as follows. in this case,
It is possible to reduce the gap between the joint end surfaces of the main roof 21 and the swiveling roof 22 when fully closed, and to reduce the laminated thickness of each roof when fully opened.

[Advantages of the Invention] As described above, according to the retractable roof of the present invention, the dome roof is divided by the plane passing through the roof ball center, and is configured to be openable and closable by the divided main roof body and the swing roof. Therefore, the main roof and the swivel roof, which are moving roofs, can be moved and moved into the upper and lower sides of the fixed roof, respectively, to open and close 100% of the large-scale space above the stadium. Moreover, each roof is an arch-shaped curved plate having curved side edges in plan view, which is formed by dividing the entire dome roof by a plane that passes through the roof sphere, so that it can be used as a fixed roof especially when fully closed or opened and closed. It has excellent stability with a moving roof, and since the economical cross section of each roof is obtained with the entire dome roof having almost the same curved surface, it is possible to exhibit excellent scenery. In addition, the main roof covering the main part above the stadium can have a short pull-in length, and since it has an economical lower structure and only one main roof, a pair of linear tracks is provided on the parallel support part. Only by doing so, the structure can be simplified, the manufacturing cost can be reduced, and the inspection and maintenance can be easily performed. Furthermore, by installing the fixed roof on the circular support part on the opening side of the main roof, when it is fully opened, a vast space spreads in front of the opposite side,
You can get a very open feeling outdoors. In this way, the contradictory requirements of the openable roof can be met very effectively.
