Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sound insulation structure for a moving partition that partitions a space such as a banquet hall or a multipurpose hall.
[0002]
[Prior art]
Conventionally, in moving partitions that are movably supported along guide rails fixed to the ceiling, some gaps remain between the partition and the ceiling or between the partition and the floor during use. Therefore, an up-and-down moving member is provided at the end of the partition main body, and the up-and-down moving member is brought into contact with the ceiling or floor to fill the gap and perform sound insulation. As such a conventional sound insulation structure, the one described in registered utility model publication No. 3002593 is known.
In this publication, the sound insulation performance is enhanced by pressing the sealing material disposed before and after the vertically moving member against the ceiling or floor.
[0003]
[Problems to be solved by the invention]
In order to improve the sound insulation performance, the moving partition is increased in size, and accordingly, the vertical moving member of the moving partition main body tends to be increased in size. Further, in order to improve the sound insulation performance by the up and down moving member, it is necessary to increase the number of sealing materials provided on the up and down moving member. There is a problem of becoming unsmooth.
Furthermore, the moving partition is always vertical because it is suspended, whereas the ceiling and floor are not necessarily completely horizontal, and it may be gently inclined in either direction or uneven. Many.
Therefore, when a vertically moving member having a single structure is protruded up and down from the partition body, the vertically moving member hits the ceiling or floor, and there is a gap between the front or back edge and the ceiling or floor. Even if there is no occurrence of a gap or a gap does not occur, an equal pressing force does not act on the front and rear sealing materials, so that the sound insulation performance of either the front or rear sealing materials may be reduced. Moreover, the smoothness of taking in and out of the vertically moving member may be lacking.
[0004]
In the present invention, in view of the above-described problems, even if the number of sealing materials for the up and down moving member is increased, the movement is performed smoothly, and the ceiling and floor are slightly inclined or uneven. It is another object of the present invention to provide a sound insulation structure for a moving partition that can be uniformly pressed against a ceiling or a floor to prevent a decrease in sound insulation performance.
