Description

[Detailed Description of the Invention] The present invention relates to a movable partition device, and more specifically,
A movable partition device for setting up a meeting room, reception hall, conference room, etc. of a desired size by moving each panel constituting the partition wall up and down within a guide rail and horizontally within the attic. It is related to.

Conventionally, as this type of movable partition device, what is generally called a sliding wall or an accordion curtain has been used.

However, as is well known, the sliding wall has a pulley attached to the upper frame of each panel constituting the partition wall to be supported by the groove of the hanger rail formed in a concave shape, and the panel is suspended through this pulley. Since it is designed to be moved laterally to open and close a large opening in a room, in order to store each panel against the wall when the large opening is opened, it is necessary to adjust the movement direction of the panel separately from the hanger rail. It is necessary to install a storage rail on the ceiling floor or the front side of the bottom section to convert the panels, and it is also necessary to install a door pocket for storing each panel on the indoor floor. For this reason, if the panel is opened and closed frequently, the attachment part of the pulley that receives the hanging load is likely to be damaged, making smooth opening and closing operations impossible. The reality is that it is not easy to transfer the panels to the hanger rail by changing their direction, and a great deal of effort and time is expended in opening and closing the panels. Moreover, the exposure of the storage rail spoils the aesthetics of the room, and the protruding door pocket makes it impossible to effectively utilize the entire floor surface of the room.

On the other hand, an accordion curtain has a frame made of hard steel that can be expanded and contracted laterally, and a soft material such as vinyl cloth is stretched over this frame as a surface material to form a corrugated wall surface. However, due to the structure of the wall surface, there is a drawback that almost no expectations can be had regarding sealing and sound insulation properties.

Therefore, it has been proposed to use a conventional panel shutter as a movable partition, roll the partition panel upwards using a drive chain, etc., and then store it by moving it horizontally within the ceiling. Since the panels are connected to each other with connecting fittings, etc. and are raised and lowered in a series, the weight of all the panels located below is loaded onto the upper connecting fittings, which may cause damage to the connecting fittings or drive Since a high load is placed on the motor and the width of the opening is limited, it cannot be used for large openings such as the object of the present invention.

The present invention has been devised based on a completely new concept in view of the above-mentioned actual situation, and its main purpose is to move each panel constituting a partition wall up and down within a guide rail and inside the ceiling. By moving horizontally, large openings in the room can be opened and closed, and when opened, each panel is stored behind the ceiling and floor, eliminating the need for a door pocket and making it possible to open and close large indoor openings. The objective is to provide a movable partition device that can effectively utilize the entire floor surface, and the technical means for this purpose is to install a plurality of panels that are not connected to each other, supported by guide rails installed on the left and right walls of the room. A partition wall to which panels are stacked vertically and attached to each other, a panel storage area in which each panel is stored in a state in which the panels are stacked vertically in a vertically stacked manner within a ceiling alcove communicating with the upper end of the guide rail, and a panel storage area in which each panel is stored in a state in which they are arranged vertically in parallel; and an electric hoisting and rewinding mechanism that locks the upper edge of each panel using a locking tool and lifts or hangs it, and between the upper position of the guide rail and the predetermined storage position of each panel in the panel storage section. , and an electric trolley mechanism having a running body movable in a horizontal direction perpendicular to the partition wall, and the movable partition is configured by a movable partition. By repeating the lifting and lowering by the hoisting and rewinding mechanism and the traversing within the panel storage part by the trolley mechanism for each individual panel, a large opening in the room can be opened and closed by electrical operation. It is characterized by the following structure.

Another object of the present invention is to electrically move each panel up and down and horizontally by hand.
Enables large openings to be opened and closed safely and accurately, eliminates wasted effort and time spent on opening and closing large openings, and allows meeting rooms, reception halls, conference rooms, etc. of desired size to be easily and quickly created.
