It relates to a suspension system for a movable wall, in which a movable wheel or a connector is attached to the lower end of one set of the movable wall, and the movable wall is suspended by the set of suspension shafts via the movable wheel or connector, and in particular, the durability of the suspension system is The aim is to reduce costs by improving performance and reducing the number of parts.

[Prior art]

A set of two hanging shafts is connected to a hanging wheel running along a hanger rail installed on the ceiling as shown above.
A movable wall is assembled and suspended, an idler or a connector is attached to the lower end of one set of the hanging shafts, and the movable wall is suspended by the two sets of hanging shafts via the idler or the connector. As a suspension system,
For example, a balancer for a movable wall is known, which is described in Japanese Patent Application No. 104541/1983.

Such a moving wall suspension system is shown in FIGS. 6 and 7. That is, in FIG. 6, 1
is a hanging wheel, which has wheels 5, 5, .

A pair of hanging bolts 2, which are examples of suspension shafts, are suspended downward from the front and back of the central portion of the hanging wheel main body 4, and the hanging belts 2 are lined up in the traveling direction of the hanging wheel 1.

In the figure, reference numeral 3 denotes a movable wall, and this movable wall 3 is configured to be movable only in a direction perpendicular to its surface.

In the illustrated example, two hanging bolts 2, 2 are suspended from two hanging wheels 1, 1 as a set, but when attaching the hanging bolts 2 to the upper surface of the movable wall 3, , move one of the four hanging bolts 2, 2, ... to the wall 3
At the same time, the other three hanging bolts 2 are provided with idlers 10 at their lower ends that run in a direction perpendicular to the traveling direction of the hanging wheel main body 4, and on the upper surface of the movable wall 3, The above-mentioned idler wheel 10 is installed in the horizontal frame 7 which has an elongated opening in the longitudinal direction.
is attached, and the movable wall 3 is suspended from the hanging bolts 2 so as to be movable in the left and right direction. Idle car 1
Connector 1 is attached to the lower end of hanging bolt 2 that does not have 0
1 is fixed, and the above 1 is connected via this connector 11.
A book hanging bolt 2 is rotatably provided with respect to a movable wall 3.

In addition, 12 in the figure is an elongated opening of the horizontal frame 7.

As described above, the hanging wheel main body 4 having the wheels 5
runs on the wheel running surface on the upper surface of the hanger rail 9, thereby moving the moving wall 3 onto the hanger rail 9.
The object is to be moved along the

Also, among the four hanging bolts 2, 2, . . . , one is rotatably fixed to the movable wall, and the other hanging bolts 2, 2, .
By being slidably attached to the movable wall 3 in the longitudinal direction via the movable wall 3, the movable wall 3 can run at an angle α with respect to the hanger rail 9 as shown in FIG. .

In this way, in the conventional suspension system for a movable wall, the idler 10 is slidable in the longitudinal direction of the movable wall 3, and the remaining hanging bolt 2 is rotated relative to the movable wall 3. By being flexible, even when the movable wall is tilted as described above, no unreasonable force is applied to the movable wall 3.Furthermore, by making the movable wall tiltable as described above, it is possible to move the room in a tilted state. It is possible to divide the room into a variety of partitions.

In addition, by suspending the movable wall 3 using two sets of two hanging bolts as described above, it is possible to prevent the movable wall from tilting with respect to the vertical plane, and it is possible to prevent the movable wall from arranging the movable walls side by side. To achieve orderly arrangement of movable walls without tilting the wall surface when partitioning a room.

[Problem that the invention attempts to solve]

However, in the conventional suspension system for moving walls as described above, three idlers and one connector are required for a total of four hanging bolts (hanging shafts), which increases the number of parts. , the cost increases, and the movable wall 3 has an angle α as shown in FIG.
When the idler vehicle 10 is tilted by the same angle, the suspension bolt 2 is structured so that it cannot rotate relative to the idler vehicle 10. Therefore, the suspension bolt 2 is distorted due to torsion, which causes the idler vehicle 10 and the suspension vehicle to tilt at the same angle. Main body 4
There was an inconvenience in that it adversely affected the durability of the connecting portion between the suspension bolt 2 and the suspension bolt 2.

In addition, since two idler cars run in parallel, two horizontal frames 7 are required, which necessitates an increase in the wall thickness of the movable wall, which also poses a problem in terms of the number of parts.

Therefore, the purpose of the present invention is to eliminate the drawbacks inherent in the conventional movable wall suspension system as described above, reduce the number of parts, contribute to cost reduction, and improve durability. It is an object of the present invention to provide a suspension device for a moving wall that can be improved.

[Means for solving problems]

In order to achieve the above object, the main means adopted by the present invention is that two sets of two hanging shafts are suspended from a hanging wheel that runs along a hanger rail installed on the ceiling. , attaching an idler or a connector to the lower end of one set of the above hanging shafts,
In the movable wall suspension device in which the movable wall is suspended by the two sets of suspension shafts via the idler or the connector, the lower ends of the two sets of suspension shafts are connected to each other by a single coupler. This is a suspension device for a movable wall, in which the lower end of each coupler body is attached to the idler body or the connector via a bearing so as to be rotatable about its vertical axis.

[Effect]

Since the present invention is constructed as described above, when the movable wall is tilted at an angle α with respect to the hanger rail as shown in FIG. Since it can pivot about its vertical axis relative to the idler or the connector, if the movable wall is tilted with respect to the hanger rail as shown in Figure 7, the coupler body will rotate relative to the idler or the connector by the amount of tilt. The vehicle will be able to rotate freely.

[Effect of idea]

Therefore, no matter how many times the movable wall is tilted with respect to the hanger rail, no torsional force is applied to the suspension shaft as in conventional devices, which may shorten the life of the suspension shaft, idler, connector, etc. There are no inconveniences. In addition, as mentioned above, the movable wall can be freely rotated relative to the hanger rail, so even if two sets of two hanging shafts are provided, the movable wall can be rotated freely relative to the hanger rail. There is no need to always arrange the movable wall at right angles to the hanger rail, and there is no problem even if the movable wall is tilted in the same direction as the hanger rail, so the diversification of partitions using the movable wall is promoted at once.

Furthermore, one idler and one
Since only one connector is required, the number of parts is reduced, which can contribute to cost reduction.

In addition, since only one horizontal frame is sufficient for the idler vehicle to run, the wall thickness can be reduced and costs can be reduced.
