Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a partitioning device that partitions a room by running a partition panel along a rail, and more specifically, a device that securely locks the partition panel in a specific position relative to the rail. The present invention also relates to a technique for making the configuration relatively simple.

[Background technology]

Conventionally, in a partition device, the partition panel is mounted on the upper and lower rails via runners provided on the partition panel side so that it can run freely, and in order to lock the partition panel from running, it is necessary to touch the upper rail from the upper and lower ends of the partition panel. The locking member that contacts the lower rail and the locking member that contacts the lower rail are protruded to lock the vehicle, but since the locking mechanism relies on friction, it is necessary to securely position the vehicle and lock the vehicle at a specific position. Therefore, relying only on friction, a large frictional force is required to lock the vehicle at a specific position.
There were problems such as the locking device being bulky.

[Purpose of invention]

The present invention was developed in view of these problems, and its purpose is to provide a partition device that can reliably position a vehicle at a specific position and lock its movement, and whose locking structure can be relatively simple. is to provide.

[Disclosure of invention]

In the present invention, a rack gear 3 is provided on the upper rail 1 and the lower rail 2 in the length direction thereof, and a pinion gear 5 is rotatably provided on the partition panel 4 side.
The pinion gear 5 is meshed with the rack gear 3, and at least one of the upper rail 1 and the lower rail 2 has a channel shape with a lip in cross section. The running tool 64 on the partition panel 4 side is guided by the running guide 68, and a notch 65 for a running lock is provided in the lip 62.
A lock body 66 which can be fitted into the notch 65 and which can be fitted into the notch 65 is provided on the partition panel 4 separately from the traveling tool 64 so that the lock body 66 can be protruded and retracted.
The present invention relates to a partitioning device characterized in that it is provided with a partition 7, and by configuring it in this way, the above object can be achieved. In other words,
By providing a notch for a travel lock in the lip of the channel-shaped rail with a lip, and inserting the lock body that is provided on the partition panel side so that it can be freely retracted into the notch, the partition panel can be reliably positioned at a specific position. In addition, the structure for locking such running can be made relatively simple by providing a notch in the lip and providing a locking body that protrudes into the notch in the partition panel. Further, a rack gear is provided on the upper rail and the lower rail in the length direction thereof, a pinion gear is rotatably provided on the partition panel side, the pinion gear is meshed with the rack gear, and a traveling guide is protruded over the entire length from the upper surface of the lip. By guiding the running tool on the partition panel side mounted on the lip with the above running guide,
The rack gear and pinion gear mesh to allow the partition panel to travel stably, while the travel tool is guided by the travel guide formed on the top surface of the lip, which stabilizes the meshing between the rack gear and pinion gear and stabilizes the partition panel's travel. It is designed so that it can be done.

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

A plurality of partition panels 4 are built so as to be freely movable between an upper rail 1 fixed to a lintel and a lower rail 2 fixed to a sill. These partition panels 4 have upper and lower rails 1,
2 in a straight line, and by bringing adjacent ones into contact with each other, the opening in the room can be closed and partitioned. In such a closed state, the running of the partition panel 4 is locked by locking means (described later) provided in the form of a penetration at the top and bottom of one end of the partition panel 4.
The positions of each are determined to prevent the partition panel 4 from opening. To open the partition panel 4 and release the partition, operate the lock handle 6 of the partition panel 4 at the right end in FIG. The partition panel 4 at the right end is opened by rotating the right end part so as to be substantially orthogonal to the upper and lower rails 1 and 2, and after this opening operation, the lock state of the remaining partition panels 4 is released one after another, Thereafter, as shown in FIG. 3, the remaining partition panels 4 are rotated around their right end portions to bring them into a non-partition state. Partition panel 4 rotated into a non-partition state in this way
are gathered at the left ends of the upper and lower rails 1 and 2, so that the interior of the room can be opened wide and the partition can be removed.

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

As shown in FIG. 5, the upper rail 1 is divided into a rack and pinion chamber 7 extending over its entire length and a runner chamber 8 below this, while the lower rail 2 has only the rack and pinion chamber 7 as shown in FIG. It is formed to the full length. A rack holding piece 9 is provided along the entire length of one vertical wall of each rack and pinion chamber 7. As shown in FIGS. 7 to 9, the rack gear is considerably shorter in length than the upper and lower rails 1 and 2. A connecting protrusion 11 is formed at one end in the length direction of the rack gear 3, and a connecting recess 12 is formed at the other end. Furthermore, an engagement groove 10 is formed in the rack gear 3 over its entire length. Thus, by engaging the engagement groove 10 with the rack holding piece 9 and connecting the connecting protrusion 11 with the connecting recess 12, the rack gear is inserted along the vertical wall on one side of the rack and pinion chamber 7 of the upper and lower rails 1 and 2. 3 is provided over the entire length of the upper and lower rails 1 and 2.
