取付けられている。As shown in FIG. 2(a), the movable roof 16 is composed of eight substantially identical fan-shaped pieces divided into eight pieces at equal angular intervals with the center of the circular central opening 14 as a base point. The side edges of each movable roof 12 overlap at adjacent portions when the opening 14 is closed, and are made of a lightweight material such as cloth or an ultra-thin metal plate. The telescopic beams 20 are aligned along their respective central axes.
A pair of idle rollers 23 are attached to both outer ends.

と外柔20aとは所定の間隔を保つようになっている。The extensible beam 20 includes an outer cable 20a and an inner cable 20 having a substantially rectangular hollow cross section.
The inner cable 20b has a basic structure shown in FIG. A plurality of mounting brackets 20d are inserted in contact with each other, and a plurality of mounting brackets 20d are protruded from the upper surface of the inner cable 20a at predetermined intervals along the longitudinal direction. The movable roof 16 protrudes outward from a guide opening 20e that serves as a guide when the movable roof 16 moves.
The movable roof 16 is fixed to the upper end of the movable roof 16.
A predetermined distance is maintained between the outer soft material 20a and the outer soft material 20a.
一方、伸縮梁20の外柔20aは固定屋根12に設けら

容された状態では、各可動屋根16は、第1図に示すよ
うに、固定屋根12上にあって開口14は開放される。Further, a steel wire, a chain, or the like attached to a power source such as a motor rotationally driven by electricity or compressed air is connected to the inner rope 20b, and when the power source is started, the inner rope 20b is When the inner cables 20b are moved in the direction of the arrow shown in FIG. 3 and the inner cables 20b are most protruded from the outer cables 20a, each movable roof 16 closes the opening 14 as shown in FIG. When the movable roof 20b is housed in the outer soft shell 2Oa, each movable roof 16 is on the fixed roof 12 and the opening 14 is open, as shown in FIG.
なお、上記固定屋根12の幅と、可動屋根1Gの長さは
、はぼ同じにして、開口14を開放した際に可動屋根1
6が、固定屋根12から外部に露出しないようにするこ
とが外観上好ましい。Note that the width of the fixed roof 12 and the length of the movable roof 1G are approximately the same, so that when the opening 14 is opened, the movable roof 1
6 is preferably not exposed to the outside from the fixed roof 12 in terms of appearance.
さて、以上の如く構成された屋根構造においては、雨天

雨水の侵入防止や太陽光の遮断ができるとともに、中間
季や晴天下には、可動屋根16を外方に移動し開口14
を開放して、天空下での運動競技を可能にする。Now, in the roof structure configured as described above, in rainy weather or in summer, the movable roof 16 is moved inward to close the opening 14, and the arch-shaped roof is completed with the fixed roof 12.
In addition to preventing the intrusion of rainwater and blocking sunlight, the movable roof 16 can be moved outward and the opening 14 can be opened in mid-season or under clear skies.
will be opened to the public to enable athletic competitions under the sky.
また、可動屋根16の移動には、伸縮梁20を使用して
いるため、ドーム中央の開口14には、固定構造の梁が
なく、開tli感が大きい。Further, since the movable roof 16 is moved using the telescopic beam 20, the opening 14 at the center of the dome does not have a fixed beam, giving a large sense of openness.
なお、上記実施例では円形の運動競技場を例示したが、
この発明は他の形状、例えば楕円、多角形でも勿論適用
できる。In addition, in the above embodiment, a circular sports stadium was illustrated, but
Of course, the present invention can also be applied to other shapes, such as ellipses and polygons.
また、中央開口14の形状も円形だけでなく、楕円、多
角形であってもよく、これを略同一形状で分割する可動
屋根16の分割数も上記実施例に限られず2以上の分割
数が採用できる。Further, the shape of the central opening 14 is not limited to a circle, but may also be an ellipse or a polygon, and the number of divisions of the movable roof 16 that divides the central opening 14 into substantially the same shape is not limited to the above embodiment, but may be two or more. Can be adopted.
さらに、可動屋根16は上記実施例のように固定屋根1
2の上方にて径方向に移動させるだけでなく、固定屋根
12の下方で移動させることや、固定屋根12の内部に
収納するようにしてもよい。Furthermore, the movable roof 16 is different from the fixed roof 1 as in the above embodiment.
In addition to being moved in the radial direction above the fixed roof 12, it may also be moved below the fixed roof 12 or stored inside the fixed roof 12.
