Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a space changing method and a space changing device for partitioning a space in a building according to a usage pattern.

[0002]

2. Description of the Related Art In recent years, it has become a great social need to make effective use of a dome mainly used for baseball and soccer so as to cope with various events other than the main purpose.

As a method of adapting such a dome space to various events, a wall curtain made of a film material is arranged inside the ceiling of the dome, and the wall curtain partitions the space horizontally. (See JP-A-6-240897 and JP-A-6-2005080).

However, this method can control the reverberation performance to some extent by lowering the ceiling height and reducing the air volume, but since the wall curtain has no reflection, sound absorption, diffusion, or sound insulation performance, it has a high performance. It was difficult to build a space. Further, since the wall curtain is always on standby above the dome ceiling, there is a design problem.

Further, when a plurality of events are held at the same time, it is necessary to partition the space vertically, but a system that meets such a request has not been proposed yet.

[0006]

It is characterized in that it has an acoustic wall that is hung from above and folded up and down, and a winding means that unwinds the wire connected to the lower end of the acoustic wall and deploys the acoustic wall.

A space variable device according to a sixth aspect of the invention is characterized in that the corners of each acoustic wall panel constituting the acoustic wall are rotatably connected by a hinge.

[0013]

In the space varying method according to the first aspect, the acoustic panel moves to a predetermined position and descends along the rails spanning the space. Next, the acoustic panel is developed at an arbitrary angle and the space is divided into partitions to construct an acoustic ceiling with excellent acoustic properties.

In the space variable method according to the second aspect, the acoustic wall folded up and down moves to a predetermined position along the rail extending into the space and expands downward. As a result, an acoustic wall having excellent acoustic properties is constructed.

In the space variable device according to the third aspect, two traveling rails are bridged in the space under the roof. A traveling beam is laid across the traveling rail, and the traveling beam travels along the traveling rail by the traveling device. An elevating panel that can be moved up and down is arranged on the traveling beam.
Further, an acoustic panel is supported on the elevating panel so that it can be undulated, and the acoustic panel is expanded at an arbitrary angle by the undulating means.

Thus, when the traveling beam stops at a predetermined position, the elevating panel descends and the acoustic panel expands at an arbitrary angle to construct an acoustic ceiling. When not in use, the acoustic panel is folded and stored, and the elevating panel rises to fit on the traveling beam.

In the space variable device according to the fourth aspect, the storage rail is provided above the traveling rail, and the traveling beam can be bridged over the storage rail. The traveling beam bridged over the storage rail is suspended and lifted by a lifter so that it can be moved back and forth between the traveling rail and the storage rail. As a result, when the acoustic panel is not used, the traveling rail is stored in the storage rail and does not stand by under the roof, so that the appearance of the entire building is improved. In addition, the building area does not increase.

In the space variable device according to the fifth aspect, the fixed rail projects into the space under the roof, and the slide rail slides along the fixed rail. A carriage is attached to the slide rail so that the carriage can travel. An acoustic wall folded up and down is suspended on the dolly. When the dolly moves to the tip of the slide rail, the winding means reels out the wire to expand the acoustic wall downward. This builds an acoustic wall.

In the space variable device according to the sixth aspect, the corners of the acoustic wall panel forming the acoustic wall are rotatably connected by a hinge. Therefore, the acoustic wall panel can be folded in two up to the inverted position (180 ° rotation).
