Description

[Detailed description of the invention] [Technical field] The present invention allows a partition body to run freely along an upper rail and a lower rail, and to partition the upper and lower rails through a rotating shaft provided at one end of the partition body. The present invention relates to a partition device whose body can be opened and rotated substantially perpendicularly, and more particularly to a technique for eliminating the gap at the bottom of the partition body.

[Background Art] Conventionally, a partition body can run freely along an upper rail and a lower rail, and the partition body can be opened and rotated to be approximately orthogonal to the upper and lower rails via a rotating shaft provided at one end of the partition body. In a movable partition device, a gap is created between the partition device and the floor when the partition device is closed, which causes problems in terms of light shielding, sound insulation, wind shielding, and the like.

[Purpose of the invention] The present invention was made in view of the above problems, and its purpose is to prevent the lower rail from being damaged not only in the vicinity of the rotating shaft but also in the lower part of the partition excluding the vicinity of the rotating shaft. An object of the present invention is to provide a partitioning device that does not create a gap between the two.

[Disclosure of the invention] The present invention allows the partition body 4 to run freely along the upper rail 1 and the lower rail 2, and to connect to the upper and lower rails 1 and 2 via a rotating shaft 85 provided at one end of the partition body 4. The partition device is configured such that the partition body 4 can be opened and rotated substantially orthogonally,
A long floor contacting member 65 is provided along the lower part of the partition body 4 except for the vicinity of the rotating shaft 85, and is movable up and down.
This relates to a partitioning device which is provided with a cover 86 that covers the gap between the partitioning body 4 and the lower rail 2 in the vicinity of the rotating shaft 85 at the bottom of the partitioning body 4, and by configuring it in this way, the above-mentioned I was able to achieve my goal. That is, by forming the floor contact member 65 over most of the partition body 4 except for the vicinity of the rotation axis 85, the partition body 4
The gap between the partition body 4 and the lower rail 2 is eliminated over most of the area, and the gap between the partition body 4 and the lower rail 2 can be hidden by the cover 86 even in the vicinity of the rotating shaft 85. be.

Embodiments of the present invention will be described in detail below based on the drawings.

A plurality of partition bodies 4 such as partition panels are movably built between an upper rail 1 fixed to a lintel and a lower rail 2 fixed to a sill. These partition bodies 4 are pulled out in a straight line along the upper and lower rails 1 and 2 as shown in FIG.
By abutting adjacent ones against each other, the opening in the room can be closed and partitioned. In such a closed state, the floor contact member 65 provided on the partition body 4, which will be described later, is used as a locking means to lock the movement and determine the position of each partition body 4, so that the partition body 4 will not open. It's like this. To open the partition body 4 and release the partition, operate the lock handle 6 of the partition body 4 at the right end in FIG. The partition body 4 at the right end is rotated around its right end portion so as to be approximately orthogonal to the upper and lower rails 1 and 2 to open it, and then the remaining partition bodies 4 are released from the locked state, as shown in Fig. 3. Then, the remaining partition members 4 are rotated around their right end portions to bring them into a non-partition state. The partition body 4 rotated into a non-partition state in this way is connected to the upper and lower rails 1 and 2.
The rooms are gathered at the left end of the room, allowing the interior of the room to be opened wide and the partition to be removed.

The configuration for performing the above operation will be described in detail below.
