Description

  The present invention relates to a moving partition device that partitions an indoor space by detachably connecting a plurality of partition panels that are suspended by rails disposed on a ceiling surface and move along the rails.

  The moving partition device is arranged on the ceiling surface by connecting the edge portions of a plurality of partition panels having a vertical dimension extending from the ceiling to the floor in offices, conference rooms, hotel event halls, etc. Depending on the rail position, it is used for partitioning into several predetermined-size partition spaces (rooms). As the partition panel constituting the conventional moving partition device, for example, as described in Patent Document 1 proposed by the present applicant, the interior between the partitioned chambers can be seen through each other through the partition panel. A pair of translucent panel plates arranged opposite to each other at a distance in the front and rear, suspended by a runner that moves along a rail that is fixed to the lower surface of the ceiling, with suspension bolts, the lower end of the floor Generally, it is configured to be able to move in a state close to the surface.

  Such a partition panel is normally assembled by attaching a vertical gutter (vertical frame) and a horizontal gutter (horizontal frame) to each side of the panel board in a state where the panel board is laid on a work table in a factory. From the standpoint of improving sound insulation characteristics, a pair of panel plates are attached to each of the front and rear sides of the frame in a state of facing each other with a space therebetween, and an internal space defined by the frame and the pair of panel plates is formed. .

  By the way, a minute foreign substance such as a dust substance floating at the assembly location may adhere to the members constituting the partition panel during assembly work. It is difficult to completely remove the adhered foreign matter before assembling the partition panel. After the partition panel is erected and installed at the installation location, it may be due to the passage of time or due to contact when connecting the plurality of partition panels. It falls by impact and easily accumulates in the inner space, particularly on the upper surface of the lower horizontal frame of the partition panel. Since the accumulated foreign matter is present at a position where it can be visually recognized from the outside of the partition panel, the appearance of the partition panel and thus the entire moving partition device may be impaired during use. As a conventional means for removing the foreign matter accumulated in the internal space of the partition panel, there is no choice but to remove the partition panel after removing it from the installation place and dismantling it. This is not practical in the case of a large partition panel.
