Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a movable partitioning device used for partitioning floors of hotels, offices, etc. as necessary.

[Prior Art] This type of movable partition device has a rail having a continuous downward opening in the bottom wall fixed to the ceiling, and a plurality of running bodies arranged to be movable within this rail. At the same time, a suspension rod is rotatably attached to the intermediate portion of each of these traveling bodies, and the lower ends of the suspension rods penetrate the downward opening and hang below the rail. The movable wall can be moved along the rail by the pair of suspension rods.

In such a movable partition device, the movable wall is generally not only slid like a sliding door, but also movable in various ways to store it in a storage position. Therefore, it is often the case that the rails are provided with branching portions so that the traveling bodies supporting the movable wall can be guided to different routes as necessary.

[Problems to be Solved by the Invention] However, although various types of guides have been developed in the past in which a traveling body is equipped with a simple guide that provides guidance for curves, it is difficult to provide a wide variety of travel routes for each traveling body. There is no one that has a function that allows automatic selection as appropriate.

Therefore, in conventional devices, each time each traveling body of each moving wall reaches a rail branching part, the person moving the moving wall applies a force in the thickness direction to the end of the wall, and It is necessary to assist the traveling body and suspension rod to follow the desired route. Therefore, it is difficult to move the movable wall, and the movable wall is likely to be unable to be guided to a predetermined storage position due to an operational error.

One possible solution to this problem is to provide a so-called point mechanism at each branching point, and to select a route for each traveling body by switching the point mechanism. However, since this type of ceiling rail is buried in the ceiling of a building and is typically used for long periods of time without inspection, incorporating movable elements into the branching section will reduce reliability. I don't like it. Furthermore, when a failure occurs, there is a problem in that repair is extremely difficult.

The present invention aims to solve these problems easily and reliably.

[Means for Solving the Problems] In order to achieve the above object, the present invention is characterized by adopting the following configuration.

That is, the movable partition device according to the present invention includes a rail that is sequentially branched in the direction of a plurality of storage positions, is fixed to the ceiling, and has a continuous downward opening in the bottom wall, and a rail that is disposed within the rail. a plurality of running bodies that are installed and can run with their intermediate portions facing the downward opening; and a rail that is rotatably attached to the intermediate portion of each of these running bodies and whose lower end side passes through the downward opening. a suspension rod hanging downward; a movable wall suspended and supported by the pair of suspension rods; and a movable wall protruding from a portion of each traveling body deviated from the suspension rod; and a selection guide surface that is provided at least at each branch part of the rail and selectively engages with the guide member to select a traveling route of each traveling body in the branch part. In the movable partition device, the hanging length of the selection guide surface of each of the branch portions is set to increase sequentially from the use position to the storage position, and the guide member provided on each of the traveling bodies is set to the selection guide surface of each of the branch parts. It is characterized by being configured so that each movable wall can be guided to a predetermined storage position by selectively guiding it with a guide surface.

[Function] With this configuration, when moving the movable wall from the use position to the storage position, each traveling body moves to the selection guide surface that engages first among the selection guide surfaces provided at each branch part. You will be guided along that branching route. However, since the selection guide surface is set so that its hanging length increases sequentially from the use position to the storage position, a traveling body having a guide member with a low protruding height can easily handle a large number of selection guides. It will pass under the surface and be guided to the selection guide surface of the deeper branch part.

In this way, each traveling object is automatically allocated to a predetermined storage position according to the set protrusion height of the guide member, so each traveling object can The moving wall can be caused to repeatedly and continuously select a traveling route in the same manner.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

This movable partition device, as schematically shown in FIG.
A rail 2 having a continuous opening 1 in the bottom wall is attached to the ceiling 3.

As schematically shown in FIG. 2, the rail 2 includes a long straight rail 7 that is in the use position and partitions the ceiling 3 of the room, and a movable wall that is sequentially connected to this straight rail 7 and whose branch ends are connected to the corresponding movable wall. 61-6. A plurality of branch portions 8, - 84 extending in a curved manner toward the storage position, and a straight line for storage that is arranged in parallel at the storage position and has one end of each connected to the corresponding branched end or non-branched end. It is composed of rails 91 to 95.

As shown in FIG. 3, the linear rail 7 is, for example, a hollow body integrally constructed from an extruded aluminum member, and has a continuous opening 1 in its bottom wall. This straight rail 7 is connected via a hanging fitting 10 having a U-shaped cross section.
It is suspended and supported by the structural members of the building at various locations.

On the other hand, for example, as shown in FIGS. 4 and 5, the branch portion 83 is a channel member 12.13.1 having a U-shaped cross section.

Then, the branched ends 8K are connected to one end 93□ of a straight rail 93 for storage, respectively, and the installation is carried out by attaching bolts 20 to one of the hanging fittings 17, 18, and 18, each having a U-shaped cross section and suspended from the building. It is fixedly supported using.

Further, the other branch portions 81, 82, and 84 are formed in the same manner as the double branch portion 83, and only the confluence end of the branch portion 81 and the non-branch end of the branch portion 84 are as shown in FIG. , the end of the straight rail 7 and the straight rail 95, respectively.
connected to one end of the

A selection guide surface 21 is provided at the branch portions 81 to 84.
．． ~21. As shown in FIGS. 6(a) to 6(d), the hanging length is set to increase from the use position to the storage position, that is, from the smaller subscript to the larger subscript. ing. Specifically, as shown in FIGS. 4 and 5, a guide rail 223 that branches along the rail center N is protruded from the bottom surface of the top plate 15.
One side of this guide rail 223 is a selection guide surface 213 that is curved into a partially arcuate shape. The other selection guide surfaces 21+, 212 and 214 are formed in the same manner.

On the other hand, as shown in FIGS. 7 to 9, the running bodies 41 to 45 disposed within the rail 2 are connected to a frame 23, respectively.
A pair of main rollers 24 are rotatably mounted on the front and rear of the rail via a horizontal shaft 25, and the main rollers 24 are rotatably loaded on the inner surface 2a of the bottom wall of the rail 2 as shown in FIG. The intermediate portion of the frame 23 faces the opening 1 of the rail 2, and the upper end of the suspension rod 5 is rotatably mounted.

Each of these running bodies 4. A pair of guide rollers 26 and 265, which are guide members, are provided at a portion of the upper surface of the frame 23 of 26 to 45 that is deviated from the suspension rod 5, that is, a portion corresponding to the front and rear main rollers 24. Each of the guide rollers 261 to 265 is rotatably mounted on two ends of a vertical shaft 27 which is fixed and deviated laterally by a predetermined distance with respect to the rail center N. Guide roller 26. It is set so that the height of ~265 is short. That is, in relation to the hanging lengths of the selection guide surfaces 211 to 214 described above, when each of the traveling bodies 41 to 44 is moved from the use position toward the storage position, the respective guide rollers 26. 264, as shown in FIG. 6, can only be engaged with the selected kite surfaces 211 to 214 having the same subscripts, and will receive a guiding action in the direction of curvature. Note that only the guide roller 265 cannot engage with any of the selection guide surfaces 211 to 214, and the traveling body 45 with the guide roller 265 protruding from the entire branch portion 8. -84 and travels to the straight rail 95.

Next, the operation of this embodiment will be explained. FIG. 1 shows a state in which the movable walls 61 to 65 are pulled out to the straight rail 7 portion where they are used, and a room is partitioned. From this state, when the first movable wall 65 is advanced along the rail 2 in the longitudinal direction, the traveling body 45 is moved to either of the selection guide surfaces 21
1 to 214, passes through all the branch parts 81 to 84, and is carried as it is to the straight rail 95. Next, when the second movable wall 64 is similarly advanced along the rail 2 in the longitudinal direction, the guide roller 264 of the traveling body 44
is a selection guide surface 211 that hangs down from each branch portion 81 to 83.
213, engages with the selection guide surface 212 hanging down from the branch portion 84, and is carried to the straight rail 94 following the branching route toward the storage position. Thereafter, in the same manner, the traveling body 43.42 of the movable wall 63.62 reaches the branch portion 83.82 having the same subscript and engages the selection guide surface 213.212 hanging down at that position, and each branch traveling route is Follow the corresponding straight rail 93.9
Transported to □. Then, only the traveling body 41 of the movable wall 61 engages with the selection guide surface 211 hanging down to the first branch portion 81, and is carried to the straight rail 91 following the branch progress route.

As described above, the movable partitioning device of this embodiment has each traveling body 4. ~4. , the set guide member 261
Predetermined storage position according to the protrusion height of ~2659. ~
95, so there is no need to perform any point switching operations, etc. to each moving wall 61 to 65.
It becomes possible to repeatedly and continuously select a traveling route in the same manner.

Moreover, the selection guide surfaces 21 provided at each branch portion 81 to 84. Since the hanging lengths of the guide members 26. to 214 of each of the traveling bodies 41 to 45 are made equal to each other, the guide members 26. Setting the protrusion height of ˜265 is simple and straightforward.

Note that the present invention is not limited to the above-mentioned embodiments, and various configurations are possible depending on the purpose and use. For example, if it is desired to accommodate a plurality of movable walls on one straight rail, guide rollers that govern the travel routes of the movable walls may be set at the same height position. Furthermore, in the above embodiment, each movable wall has a property that even if it is placed under a relatively different arrangement relationship at the use position, if it is stored, each movable wall will eventually be stored on a straight rail having the same subscript. Therefore, by utilizing this property, a wide variety of other setting modes are possible depending on the purpose and use.

[Effects of the Invention] Since the present invention has the above configuration, the following effects can be obtained.

That is, the height of each guide member protruding from the moving body of the moving wall is set individually, and a selection guide surface that selectively engages with the guide member is set at the branching part of the rail, and the hanging length of this selection guide surface is set. Since the height of each traveling body is set to increase from the use position to the storage position, the shorter the guide member is, the more the traveling body can pass under a large number of selection guide surfaces 12-. You will be guided by the selection guide surface in the recessed branch. In this way, the branching route of each traveling body is specified by the set value of the protrusion height of the guide member, and no matter where the movable wall is placed in the usage position,
The movable wall can be automatically and repeatedly guided to a predetermined storage position. Therefore, there is no need to provide any movable parts such as a point mechanism, improving reliability, easy operation, and greatly simplifying the storage procedure. It is something that can be done. Moreover, since the hanging lengths of the selection guide surfaces provided at each branch portion are sequentially varied, the protrusion height of the guide member of each traveling body can be set simply and clearly.
