Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving partitioning device used for partitioning a room, and more particularly to a sound insulation structure thereof.

[0002]

2. Description of the Related Art Conventionally, in order to partition a large room at an event or the like, a plurality of moving partitions are arranged in a row and divided into small rooms, and after the event is completed, the moving partition is moved to the original position. Returning to a large room is taking place. In this case, when using a partition that is movably suspended along a guide rail fixed to the ceiling, during use, the partition may be installed between the partition and the ceiling or floor of the room to be partitioned, and also between the side walls (pillars). Since a slight gap remains, a moving member is provided at the end of the partition main body, and the moving member is brought into close contact with the ceiling, floor surface, side wall, etc. to fill the gap, thereby achieving sound insulation and smoke prevention. As such a conventional sound insulation structure, there is one as described in Registered Utility Model Publication No. 3002593.

Further, the outermost moving partition for partitioning the room is of a lateral expansion type in which one side portion thereof can be extended in the left-right direction, whereby the entire frontage can be completely closed. Many. However, in this case, when one side portion is expanded in the left-right direction and the moving member is extended in the vertical direction, a gap is formed above and below the expanded side portion, and sound may leak from this gap. is there. As means for closing the gap generated in such a corner portion, as disclosed in, for example, Japanese Utility Model Publication No. Sho 55-31195, one side portion of the upper and lower moving members cooperates with the side moving member. In some cases, a side sliding member that moves in the left-right direction is mounted so as to be slidable in the left-right direction.

[0004]

In the former sound insulation structure, the upper and lower end faces are provided with the concave grooves facing the longitudinal direction, the moving member is fitted therein, and the sealing material is provided between the concave groove and the moving member. Is installed so as to insulate sound. However, even in this sound insulation structure, since the inside of the concave groove is hollow, sound leakage still occurs through this hollow portion, and the sound insulation performance is inferior to that of the fixed sound insulation wall. Further, in the latter lateral expansion type moving partition which is provided with the gap closing means at the latter corner,
When the upper and lower moving members expand vertically and the side moving member expands laterally, there are many cavities in addition to the voids due to the movement of the side moving members, and sound leaks through them. There is a risk.

The present invention has been made in view of the above-mentioned problems of the prior art, and provides a moving partitioning device with improved sound insulation performance around a moving member, particularly around a moving member at a corner. It is intended to be provided.
