Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving partition for traveling in a curve and a branching device therefor.

[0002]

2. Description of the Related Art A moving partition is constructed so that it can be pulled out from a storage part in order to partition a large space into a smaller space. A traveling rail is arranged on the ceiling, and a suspension vehicle attached to the upper end of the partition is used for the above traveling. It is installed on rails and rolls. Such moving partitions include a cross traveling type moving partition and a curve traveling type moving partition depending on the form of the traveling rail arranged on the ceiling. In the former partition, the traveling rails intersect in a cross shape or a T shape. On the other hand, the latter partition uses curved rails. Of course, each has advantages and disadvantages, and it is only necessary to use an appropriate one according to the application, but the present invention is intended for the latter curve traveling type moving partition, and FIG. The outline of a curved traveling type moving partition is shown.

By the way, the curved traveling type moving partition shown in the figure has two storages, and the partition stored in the storages is pulled out to partition a predetermined room space. Therefore, each storage rail (b), (b) ... branches off from the drawer rail (a), and the storage rail
Moving panels (c), (c) ... are hung from (b) and (b). Here, a branch block is provided at the portion B between the drawer rail (a) and the storage rail (b). In the curve type moving partition, each moving panel (C),
(C) The location where ... is stored is predetermined, and a predetermined suspension vehicle will not enter the other storage rail (b).

A partition rail (d) is continuous with the drawer rail (a), and the moving panels (c), (c) ... Are arranged along the partition rail (d). FIG. 4 shows a suspension vehicle installed in a branch block B between the drawer rail (a) and the storage rail (b). As shown in the figure, a guide block (e) is fixed to the ceiling of the rail, and a guide roller (f) is attached to the upper part of the suspension vehicle. The guide roller (f) hits the guide block (e) to determine the traveling direction of the suspension vehicle, that is, the storage rail (b) into which the suspension vehicle enters. Therefore, the guide block (e) in each branch block B
And the height of the guide roller (f) of each suspension car is adjusted.

Although a large room is partitioned by the curved traveling type moving partition shown in FIG. 3, there are only one partition method. However, in reality, as shown in FIG. 5, it is desired to change the size of the partitioned room. Therefore, there are three partition rails (g), (h) and (ri) on the ceiling rail of the room. However, in the structure of the suspension vehicle or rail shown in FIG.
A suspension vehicle cannot enter by freely selecting (G), (H), or (R).

Therefore, even in such a curved traveling type moving partition, a partition rail is selected and the moving panel is selected.
As conventional examples capable of moving (C), (C) ..., Japanese Utility Model Laid-Open No. 5-45738 and Japanese Patent Application Laid-Open No. 2-108777 are known. However, the device described in each of these publications has a complicated structure and is high in cost, and cannot be used easily.

[0007]

As described above, the conventional curved traveling type moving partition has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a rail branching device capable of selecting a rail to enter, and a curve traveling type moving partition provided with a plurality of partition rails.

[0008]

In the rail branching device of the present invention, a swing cam is attached to the branching portion of the rail. The swing cam has a structure capable of swinging by a predetermined driving means, and can close the guide groove of one of the branched rails. Therefore, the suspension vehicle cannot move to the closed rail side, and the traveling direction of the suspension vehicle can be freely selected by operating the swing cam.

Here, the driving means for the swing cam is not particularly limited, and for example, a rotary cam, a magnet, a gear mechanism or the like can be adopted. An indicator lamp is provided on the ceiling near the branch portion so that the position of the swing cam can be known by blinking the lamp. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0010]

1 (a), 1 (b), 2 (a) and 2 (b) are schematic views of a branching device for a curved traveling type moving partition of the present invention. This branching device is attached to the branching portion A in FIG. 5 and controls the suspension vehicle so as to travel to the partition rail (g) or the partition rail (h). Further, as shown in FIG. 4, the suspension vehicle which is installed in the rail and suspends the moving panel has a guide roller attached to the upper portion thereof, and the route for the suspension vehicle to enter the storage rail is regulated. However, the number and height of the guide rollers are determined by the relationship between the pull-out rail and the guide block mounted on the branch portion of the storage rail.

In FIGS. 1 and 2, 1 is a swing cam, 2 is a rotary cam, 3 is a coil spring, and the swing cam 1 is attached by cutting a part of a rail running piece 4. . A support shaft 5 is provided on one side of the swing cam 1, and the support shaft 5
Is attached to the traveling piece 4, and the swing cam 1 can swing about the support shaft 5. Since the upper surface of the swing cam 1 is flush with the traveling piece 4 and the wheels of the suspension vehicle 6 roll, the swing cam 1 cannot be supported by a cantilever type using only the support shaft 5. Therefore, a notch is formed at the tip of the swing cam 1, and the swing cam 1 is supported by being meshed with the notch provided in the traveling piece 4 (see FIG. 2B).

Further, the inner peripheral surface 7 of the swing cam 1 is curved along the guide groove 8a so that the suspension vehicle 6 can move smoothly without any obstacle. (A) of the figure shows the case where the rocking cam 1 closes the guide groove 8b and opens the guide groove 8a side. However, the rotary cam 2 rotates and the rocking cam 1 rocks. The guide groove 8b can be opened as shown in FIG. Here, the swing cam 1 has a coil spring 3
Are connected to each other and urge a spring force to draw them toward the rotary cam 2. Therefore, the swing cam 1 does not separate from the rotary cam 2 and can swing with the rotation of the rotary cam 2.

The rotary cam 2 rotates about its shaft 9, and a motor 10 is provided on the ceiling to drive the rotary cam 2. However, the shaft 9 extends the plug 11 downward so that the motor 10 can be operated even when the motor 10 is not operated due to a power failure or the like. Therefore, the ceiling panel 13
The socket can be fitted into the plug 11 through the opening of and the rotating cam 2 can be rotated by the handle.

By the way, when the moving panel is moved, it is not known in which direction the swing cam 1 faces and which guide groove is closed. Therefore, the dock 12 is extended to the rocking cam 1 and rocked together with the rocking cam 1, and the tip position of the dock 12 is detected by a sensor. In the figure, proximity switches 14a and 14b are used as sensors, and when the tip of the dock 12 is in proximity to the proximity switch 14a, only the guide groove 8a is opened and the suspension vehicle 6 moves in a curved manner. On the contrary, if the tip of the dock 12 is close to the proximity switch 14b, the guide groove 8b is opened, and the suspension vehicle 6 goes straight. Then, a lamp is provided on the ceiling surface to display which side of the guide groove is open.

The rotary cam 2 is brought into contact with the swing cam 1 to swing the swing cam 1. The swing cam 1 shown in FIG.
As shown in (b), the cam roller 15 is rotatably supported, and the rotary cam 2 is in contact with the cam roller 15.
Reference numeral 16 in the figure is a pin for fixing one end of the coil spring 3 connected to the swing cam 1. The other end of the coil spring 3 is fixed to a fixed pin 17 provided on the rail side.

As described above, in the branching device of the present invention, the swinging cam is attached to the branching portion and the guide groove is opened / closed so that the traveling direction of the suspension vehicle can be selected.
In the above embodiment, the rotary cam 2 is used as the swinging means of the swinging cam, but the driving means for swinging the swinging cam 1 is not limited. For example, a worm gear can be attached to the support shaft 5 and a worm can be engaged with this gear, or it can be swung using an electromagnet. If a groove cam is used as the rotating cam and the cam roller 15 attached to the swing cam 1 is loosely fitted in the groove, the swing cam 1 is completely restrained by the rotating cam, and thus the coil spring 3 is not required. .

The swing cam 1 shown in FIG. 1 has a guide groove 8
Since the opening a is opened, the suspension vehicle 6 can move only along the guide groove 8a. When the swing cam 1 is retracted and the guide groove 8b is also opened, the suspension vehicle 6 moves along the linear guide groove 8b. As described above, the branching device of the present invention has the swing cam attached to the branching portion, and the following effects can be obtained.

[0018]

The branch device of the curved traveling type moving partition according to the present invention has a swing cam attached to the branch part. Since the swinging cam opens and closes the guide groove of the rail, the traveling direction of the suspension vehicle of the moving panel is restricted, and the traveling direction can be appropriately selected at the branch portion of the rail to proceed. Therefore, even in the case of a curved traveling type moving partition, it is possible to provide partition rails at a plurality of places to change the partitioning method of the room.
And, the branching device of the present invention is for attaching the swing cam to the branching part of the rail, and its structure is simple,
A stable branch operation can be performed with few failures.
