Description

[Detailed description of the invention] [Technical field] The present invention relates to a partition device that partitions a room by running a partition panel along a rail, and more specifically, the invention relates to a partition device that partitions a room by running a partition panel along a rail. Regarding the technology to be used.

[Background Art] Conventionally, a partition device has a configuration in which a runner is mounted on the partition panel side with respect to the rail so as to be freely movable. However, with such a configuration, when the partition panel is run along the rail, the left and right sides are not easy to move due to the slip caused by the runner in the running direction and the left and right clearance between the runner and the rail that is required for running. There was a problem with sagging. To solve this problem, it has been proposed, as in Japanese Utility Model Application Publication No. 60-77679, that a pinion gear on the partition body side is engaged with a rack gear body on the rail side. There was a problem in that it was difficult to stabilize the meshing.

[Purpose of the invention] The present invention was made in view of the above problems, and its purpose is to eliminate the rattling of the running and allow smooth running, especially for the rack gear on the rail side. To provide a partition device capable of stabilizing the meshing between the pinion gear and the pinion gear on the partition panel side.

[Disclosure of the invention] The invention provides a rack gear 3 on one vertical wall of the upper rail 1 and the lower rail 2 over the entire length of the rail,
A pinion shaft 22 is rotatably provided on the partition panel 4, a pinion gear 5 is fixed to the pinion shaft 22, the pinion gear 5 is meshed with the rack gear 3, and the partition panel 4 is built into the upper and lower rails 1 and 2 so as to be freely movable, thereby creating a partition. A slider 43 to be inserted into the lower rail 2 is attached to the pinion shaft 22 hanging down from the lower end of the panel 4 so that the pinion shaft 22 can rotate freely, and the slider 43 holds the bearing 44. , the pinion shaft 22 is fitted into the bearing 44, the bearing 44 is brought into sliding contact with the rail opening edge, and the runner 13 is provided on the pinion shaft 22 protruding from the upper end of the partition panel 4. Runners 13 are rotatably provided around a horizontal axis on both sides in a direction substantially orthogonal to the running direction of the upper rail 1, and the runners 13 are rotatably mounted on a runner receiving surface 14 of the upper rail 1. The present invention relates to a partitioning device, and by configuring it in this way, the above object can be achieved. In other words, by meshing the rack gear 3 and the pinion gear 5, the partition panel 4 can be reliably run without slipping in the running direction, and moreover, the slider 43 can be inserted into the lower rail 2. Slider 43
By sliding the bearing 44 held on the rail opening edge, side-to-side rattling is suppressed to ensure reliable engagement between the rack gear 3 and the pinion gear 5, and the runner 13 is provided on the pinion shaft 22. , runners 13 are provided on both sides of the pinion shaft 22 in a direction substantially orthogonal to the traveling direction thereof so as to be freely rotatable around a horizontal axis, and the runners 13 are mounted on the runner receiving surface 14 of the upper rail 1 so as to be freely rollable. This prevents an unbalanced load from acting on the pinion shaft 22, which is the case when the runner 13 is provided only on one side of the pinion shaft 22, and stabilizes the meshing between the rack gear 3 and pinion gear 5, thereby reducing backlash. This allows for stable driving without bumps.

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 locking means provided in the upper and lower portions of one side of the partition panel 4 locks the movement of the partition panel 4, fixes the position of each partition panel 4, and secures the partition panel 4. It is made so that it cannot be opened. 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 rotated around its right end portion so as to be approximately perpendicular to the upper and lower rails 1 and 2 to open it, and then the remaining partition panel 4 is moved slightly within the range of its locked state. By releasing the contact between the partition panels 4, the locked state of the remaining partition panels 4 is automatically released, and then as shown in FIG. 3, the right end portion of each of the remaining partition panels 4 is released. It is rotated around the center to create a non-partitioned state. The partition panel 4 thus rotated into a non-partitioning state is gathered at the left end of the upper and lower rails 1 and 2, so that the opening in the room can be opened wide and the partition can be released.

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.

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.

Rack gears 3 provided in the rack and pinion chambers 7 of the upper and lower rails 1 and 2 mesh with pinion gears 5 provided on the partition panel 4 side so as to be horizontally rotatable, and also on the partition panel 4 side so as to be freely rotatable up and down about a horizontal axis. A runner 13 provided in the runner chamber 8 of the upper rail 1 is rotatably mounted on the runner receiving surface 14 of the runner chamber 8 of the upper rail 1, and when the partition panel 4 runs, the pinion gear 5 meshes with the rack gear 3. The runner 13 is configured to roll on the runner receiving surface 14 while maintaining the engaged state. In this way, the pinion gear 5 is connected to the rack gear 3.
By making the partition panel 4 travel while meshing with each other, the travel amount of the upper and lower parts of the partition panel 4 is made equal, so that the partition panel 4 can travel without wobbling. In such case,
The load of the partition panel 4 is not applied to the meshing portion between the rack gear 3 and the pinion gear 5, so that no force is applied to the meshing state. The configuration will be explained below.

Since the pinion gear is engaged with the rack gear and the partition panel is built into the upper and lower rails so that it can run freely, in other words, the pinion gear is engaged with the rack gear and the partition panel is made to run, so it can run without slipping or the like. This has the advantage that the amount of movement can be determined, and that it can be run without rattling compared to running with a conventional running implement such as a runner. Moreover, a slider to be inserted into the lower rail is attached to the pinion shaft so that the pinion shaft can rotate freely, the slider is made to hold a bearing, the pinion shaft is fitted into the bearing, and the bearing is attached to the rail. Since the runner is in sliding contact with the opening edge, it is possible to suppress side-to-side rattling and ensure meshing between the rack gear and pinion gear.Also, since the runner is provided on the pinion shaft, it is possible to provide a runner that is approximately perpendicular to the running direction of the pinion shaft. Runners are provided on both sides of the pinion shaft so that they can rotate around the horizontal axis, and the runners are mounted on the runner receiving surface of the upper rail so that they can roll freely. This has the advantage of stabilizing the meshing between the gear and the pinion gear, which also allows for stable running over a long period of time.
