Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention is applicable to various sports (baseball, rugby, soccer, American football, etc.).
And ceiling equipment such as multi-purpose large space structures represented by dome-shaped structures used for various events (concerts, circus, fairs, fairs, conferences, motorcycle races, etc.).

[0002]

2. Description of the Related Art For example, as a conventional dome-shaped structure which is used for multiple purposes as described above, a dome type roof itself serves as a ceiling.

[0003]

However, according to the above-mentioned conventional technique, since the roof height, that is, the ceiling height is fixed, there are the following drawbacks. In other words, the roof height is designed to meet the condition that requires the highest space among various conditions of use, so it can be optimally used during use that requires such a high space. When using it for meetings, concerts, etc., the roof height is too high, and the usability is very poor.
Especially during use such as concerts where acoustic performance is important,
It was difficult to sufficiently achieve the intended purpose of multipurpose use, because the reverberation time was unduly long due to too much air volume, and it could not be used in some cases. An object of the present invention is to provide a ceiling facility that can reasonably show a ceiling height according to usage conditions and is particularly useful for a large space building.

[0004]

The ceiling equipment of the present invention is characterized in that a plurality of ceiling constituent members forming a ceiling surface are arranged so as to be able to move up and down, and the ceiling height changing means for raising and lowering the ceiling constituent members is a ceiling. The point is that a chain-like body for suspending and supporting the constituent material on the upper body and an adjusting means for adjusting the suspension height by the chain-like body are provided. As the ceiling height changing means, it is preferable to provide a means for individually moving up and down each ceiling component.

[0005]

The height of the ceiling surface can be changed by raising and lowering the ceiling component by the ceiling height changing means. Moreover, because the ceiling surface is composed of multiple ceiling components,
By raising and lowering each ceiling constituent member separately and changing the height of each ceiling constituent member separately, not only the ceiling height but also the shape of the ceiling surface can be changed. Moreover, since the ceiling component is suspended and supported, the lower space of the ceiling is not occupied for supporting the ceiling component, and the availability of the lower space is not impaired. Furthermore, since the ceiling component is suspended and supported by a chain (chain) that does not expand or contract regardless of changes in the suspension load, it is not a wire that expands or contracts due to variations in the suspension load, so even if the suspension system is adopted, Even if the ceiling components are used to support lighting equipment and audio equipment (such as speakers), and the ceiling components are also used for the installation parts of those facilities, to simplify the overall configuration (that is, the suspension load changes). Even in the case), the ceiling component can be reliably and strongly installed at a predetermined height position and accurately.

[0006]

Therefore, according to the present invention, the ceiling height can be adjusted safely and accurately, and when applied to a multipurpose large space building, the ceiling height can be adjusted according to the purpose of use. By revealing it, it is possible to effectively perform multipurpose use of a large space building, and moreover, the shape of the ceiling can be adjusted, and the shape of the ceiling makes it easy to meet the purpose of use. Can be effectively used for multiple purposes,
Therefore, as a whole, it is possible to provide a ceiling installation that can effectively make a large-scale building usable for multiple purposes.
