Description

The present invention relates to an openable dome.

[Related Art] In recent years, a dome building with a roof that opens and closes has been developed as a facility for sports such as baseball and various events.

This type of retractable dome can be closed when it is necessary to prevent rain or cold, and can be opened when an open environment is required in search of the sun or wind. .

Conventionally, as this kind of openable dome, for example, those shown in FIGS. 11 (A) to 11 (E) disclosed on pages 130 and 131 of Nikkei Architecture, March 6, 1989, issue There is.

That is, FIG. 11 (A) shows two arch-shaped domes.
10 is a method of moving horizontally to the left and right of the building facility 9 and opening and closing, and the thing of FIG. 11 (B) is such that a plurality of subdivided arched domes 11 move horizontally to the left and right and overlap. FIG. 11 (C) shows an open system in which two sets of folding arched domes 12 are folded right and left, and FIG. 11 (D) shows a roof element. In FIG. 11 (E), the roof element 14 is moved up and down and opened while being overlapped.

[Problems to be Solved by the Invention] However, FIGS. 11 (A) to 11 (C)
As each dome 10, 11, 12 moves to the outside of the building 9,
It is necessary to secure a large site around the building 9, and in the case of the above-mentioned FIGS. 11 (D) and (E), a part of the roof element remains in the sky, so that it is bothersome and has a sufficient feeling of freedom. There were problems such as inability to do so.

The present invention has been made in order to solve the above-mentioned conventional problems, and an object of the present invention is to eliminate the necessity of providing a site or space for storing an open roof in the vicinity of a building facility, and to provide an opening. An object of the present invention is to provide an openable / closable dome that can improve the rate and fully enjoy a feeling of freedom.

Means for Solving the Problems An openable dome according to the present invention has an outer peripheral structure having an opening edge at an upper part, and first and second guides installed at opposite wing positions of the opening edge of the outer peripheral structure. In an openable / closable dome comprising a roof and a plurality of segment roofs movable while being guided by these guide roofs, at least a semicircular rail is laid near an opening edge of the outer peripheral structure, and the rail is arranged along the rail. In this case, the second guide roof is moved to be stored inside or outside the first guide roof. It is also characterized in that the first guide roof is moved along the opening edge of the outer peripheral structure.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 to 4, reference numeral 1 denotes an outer peripheral structure, which is formed in a low frustoconical shell shape having a substantially circular opening edge 1a at the top. The outer peripheral structure 1 may be any of a wall structure, a frame structure and a combination structure as in the embodiment.

A viewing stand 1b is provided inside the outer peripheral structure 1. The viewing stand 1b may not be provided depending on the purpose of use of the building.

Reference numerals 2 and 3 denote first and second guide roofs each having a semimoon-shaped curved surface, which are respectively arranged opposite to both inner wings of the opening edge 1a of the outer peripheral structure 1. As shown in FIG. 3A, a roller 3c is attached to a lower portion of the second guide roof 3, and is guided by a rail 1c laid in a semicircular shape near an opening edge 1a of the outer peripheral structure 1 so as to be opposed to each other. Move to the side,
It overlaps with the inside of the first guide roof 2.
Incidentally, the rail 1c may be circular.

The facing inner edges 2a, 3a of the first and second guide roofs 2, 3 are parallel to each other, and a plurality of sheets (eight sheets in this embodiment) are provided between the inner edges 2a, 3a. ) Is installed.

The segment roof 4 is an arcuate curved plate that is divided into small parts. As is clear from FIGS. 3B and 3C, the rollers 4a provided at both ends of the segment roof 4 are provided with the first and second rollers. The guide roofs 2 and 3 move and open and close while being guided by guide rails 2b and 3b arranged along the arc near the inner edges 2a and 3a of the guide roofs 2 and 3, respectively. Each segment roof 4
At the joints between them and the joints with the first and second guide roofs 2 and 3, measures are taken to prevent rain leakage.

Next, the operation of opening and closing the roof of the openable dome of the above embodiment will be described.

First, from the state where the roof shown in FIG. 1 is closed, as shown by arrows in FIG. 5, a total of eight segment roofs 4 are arranged in parallel from the center to the outer peripheral structure 1 on both sides in order from the center. Move and open. The segment roofs 4 moved in the direction of the outer peripheral structure 1 are sequentially stored in a storage space 1d formed inside the outer peripheral structure 1, as shown in FIG.

The number and size of the segment roofs 4 are not limited to those in the above embodiment, but may be set as appropriate according to the structural strength, the scale of the building, and the like. Also, all the segment roofs 4 may be moved to only one side. Furthermore, as a storage location of the segment roof 4,
In addition to the inside of the outer peripheral structure 1, an underground space formed outside or below may be used. If necessary, a part of the plurality of segment roofs 4 may be retained in the middle of the moving path to enhance the effect.

After all the segment roofs 4 are stored inside the outer peripheral structure 1, the guide roofs 2, 3 remain on both wings of the outer peripheral structure 1, as shown in FIG. Subsequently, as shown in FIG. 8, the second guide roof 3 is connected to the rail 1c (see FIG. 3A).
And housed so as to overlap the inside of the first guide roof 2 as shown in FIG.

Note that the second guide roof 3 may be housed outside the first guide roof 2. Further, the first guide roof 2 may not be fixed but may be movable similarly to the second guide roof 3. In this case, two sets of the rails 1c are required.

FIG. 10 shows another embodiment in which the segment roof 4 is stepped.

[Effects of the Invention] (1) By overlapping two guide roofs, the aperture ratio can be greatly improved, so that there is little shading on the fieldmen and a sufficient feeling of freedom can be enjoyed. In particular, by positioning the fixed-side guide roof to the north (in the Northern Hemisphere), shadows can be minimized even when the sunlight is inclined.

(2) The opening / closing state is changed by arbitrarily setting the opening / closing position of the segment roof or the guide roof,
Various fields and audience seats can be produced.

(3) Both the open and closed states of the roof are clear and beautiful, and the design is excellent.
