Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a movable partition wall for partitioning rooms in a building, which is suspended from a guide rail via a runner. The present invention relates to the structure of a suspension device for moving along.

[Conventional technology]

Conventionally, this type of movable partition wall has been configured to be movably suspended from a hollow guide rail attached to the ceiling or the like via runners so that it can move along the guide rail. As is well known, in this case, the runner can smoothly switch from the main guide rail to the branch guide rail or vice versa at a direction change point provided in the middle of the guide rail without falling off the guide rail. It is necessary to change direction.

Therefore, the applicant of the present application
In No. 173579 (Japanese Patent Application Laid-Open No. 57-96182), the upper surface of the runner fitted in the hollow guide rail is shifted toward the center of the turning radius when turning from the main guide rail to the branch rail or vice versa. One guided body is provided to protrude upward at the part, and the direction change part has a side surface abutting surface where the side surface of the guided body comes into contact with, and a front surface abutting surface where the front surface of the guided body comes into contact with. It was proposed to provide a derivative with

According to the suspension device that is desired in the future, when the runner comes to a direction change point while moving along the main guide rail, the front and side surfaces of the guided body provided on the upper surface of the runner will reach the direction change point. By abutting the front surface contact and the side surface contact of the provided guide body substantially simultaneously, the runner turns around the guided body, so that the turning radius when changing direction can be made small.

[Problem to be solved by the invention]

However, the above-mentioned suspension device of the prior application is provided with one wheel on each side of the runner, the axis of rotation of which is oriented substantially horizontally, and the lower ends of both the left and right wheels are attached to the left and right side plates of the guide rail. It is configured so that it comes into contact with the upper surface of both runner receiving plates provided facing inward, and when turning in the above direction, the wheels on both the left and right sides of the runner are located on the outer side with respect to the turning direction. When the wheel on one side moves from one runner receiving plate to the other runner receiving plate on the guide rail, it falls into the open passage formed between the two runner receiving plates, so it is difficult to move during the turn. If the movable partition wall is tilted, and the weight of the movable partition wall is large, there is a problem in that the wheels on one side remain depressed in the open passage, resulting in an inability to turn. .

Moreover, since the suspension device of the prior application is provided with only one guided body that comes into contact with the guiding body on the upper surface of the runner, the rotation of the runner is caused by the single guided body. In other words, the turning of the runner starts when the front surface of the runner comes into contact with the front surface of the inductor. As the turning is done rapidly,
the wheels on one side falling into the open passage;
This, together with the fact that the front surface of the guided body comes into violent contact with the front surface of the guided body, not only generates large noises and impacts, but also causes problems in that smooth turning is significantly hindered.

An object of the present invention is to reduce the turning radius when changing direction, while solving various problems of the suspension device of the prior application.

[Means to solve the problem]

In order to achieve this object, the present invention provides a hollow main guide rail with an inwardly facing runner receiving plate at the lower end of the left and right side plates.
Similarly, hollow branch guide rails with inward runner receiving plates are connected to the lower ends of both left and right side panels to form direction change points, and the runners are moved in the longitudinal direction of each guide rail into these guide rails. In a suspension support device for a suspended type movable partition wall, which is freely inserted into the runner and a movable partition wall is suspended from the runner via a suspension shaft, the runner has a movable partition wall in front of the suspension shaft. Wheels are provided at four locations on both left and right sides and on both left and right sides rearward from the hanging shaft, respectively, so as to contact the upper surfaces of both runner receiving plates in each guide rail, with the rotation axes of the wheels oriented substantially horizontally. , and on the upper surface of the runner, an upwardly extending portion is disposed on the left and right sides of the suspension axis at a portion that is shifted toward the center of the turning radius when turning from the main guide rail to the branch guide rail or vice versa. Two protruding guided bodies are provided at the front and rear parts of the hanging shaft, while a downwardly protruding guide body is provided in each guide rail at the direction change point, and the guide body has a flat surface. A contact surface formed to be curved from the main guide rail to the branch guide rail in view is provided, and the contact surface is provided with:
The guide rail is configured such that the guided object comes into contact with the guide rail, and the abutting surface is formed at a position shifted from the longitudinal center line of each guide rail toward the center of the turning radius in plan view.

[Effect]

In this configuration, when the runner moving along the main guide rail approaches the direction change point, the guided object located in front of the hanging shaft among both guided objects provided on the upper surface of the runner is installed at the direction change point. By coming into contact with the curved abutting surface of the guide, the runner starts turning in the direction from the main guide rail to the branch guide rail, so the directional turning is based on the radius of curvature of the abutting surface. This means that the turning radius is approximately equal to , and the turning radius is relatively gentle, making it possible to avoid the violent collision of the guided object with the guiding object, as in the case of the prior application.

On the other hand, by providing wheels that come into contact with the upper surfaces of both runner receiving plates in each guide rail at four locations on both left and right sides of the front part of the runner and on both left and right sides of the rear part, when the runner turns in the direction, With the rear wheel of both front and rear wheels on the outside of the turning radius riding on one runner receiving surface, the front wheel transfers from one runner receiving plate to the other runner receiving plate, and then the front wheel After the rear wheel has almost transferred to the other runner receiving plate, the rear wheel will transfer from one runner receiving plate to the other runner receiving plate. This avoids falling into the open passages between the plates.

〔Effect of the invention〕

Therefore, according to the present invention, although the direction of the runner with the movable partition wall suspended can be changed with a small turning radius at the direction change point between the main guide rail and the branch guide rail, it is possible to change the direction of the runner with a small turning radius during the direction change. This has the effect of reliably preventing the generation of noise and impact and tilting of the movable partition wall, as well as allowing the runner to change direction smoothly.
