Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging wheel for suspending and running (moving) a wall panel of a movable partition (hereinafter referred to as a panel), and a technology for its running rail, and further relates to a technique for changing the direction of the panel, particularly at right angles. This relates to technology for changing direction on running rails that intersect with each other.

The panels shall be of considerable weight.

BACKGROUND ART Conventionally, there has been a demand for a panel suspension traveling device to be able to stably travel the panel and to be able to easily change direction. Orientation is necessary to move panels to create new or eliminate partitions.

In the hanging traveling device for panels that changes direction at right-angle intersections using vertical wheels according to the present invention, it is easy to achieve stable traveling on the traveling rail, but it is not possible to easily advance or change direction at the intersection of the rails. . In other words, vertical wheels that rotate in the vertical direction are excellent in carrying the weight of the panel and traveling in a straight line on running rails, but vertical wheels cannot handle right-angled intersections at rail intersections by themselves. In addition, the wheel sheath of the running rail (the interior that accommodates the suspended vehicle) and the suspended vehicle housed in the by-bi can become unstable due to the expansion of the wheel sheath at the GJ rule intersection. 6 at the rail intersection
jAnother problem is that the bottom of the wheel on which the vertical wheel is mounted is cut off by the intersection of the sliding grooves on which the hanging shaft of the hanging wheel slides, and the vertical wheel falls into the sliding groove, making it impossible to proceed. Become.

For this reason, vertical wheels were installed on the four sides of the rectangular parallelepiped on both the left and right sides and front and back, and at rail intersections, all of these vertical wheels were not floated and used, and instead of being used on the top of the chassis or under the GJ. The hanging wheel (
(For example, Ll
Jitko No. 61-9958, Jitko No. 61-36708,
Special public defect number 62-17062).

The disadvantages of this conventional device are that it is difficult to support the lower ball at the same height as the bottom of the wheel, and that the ball on 4j makes contact with the newly installed suspension pillar at the intersection, making it difficult to support it. It is to do something. In other words, it is difficult to maintain the same height of the suspended wheel on the traveling rail by placing the wheels on the bottom of the wheel because the support for the bottom of the wheel is cut off at the rail intersection as described above. This is because, as mentioned above, at the intersection, height differences are provided to support the hanging wheel only with the balls and to float the front, rear, left and right vertical wheels.

Further, the contact between the ball and the running rail is at a point, and there is no problem in that the ball does not rotate smoothly.
With the ball, the load on the panel is weak, making it unsuitable for running heavy panels weighing more than 100 kg, especially over 500 kg, at intersections. This poses a serious problem in escaping the intersection by switching to

Furthermore, these conventional devices have the biggest drawback that they are almost impossible to stop correctly at intersections. In other words, as mentioned above, the wheel sheaths spread out at the rail intersection, and the hanging vehicle G is in an unstable condition because its left and right sides and front and back are not restricted by the side edges of the traveling rails, etc., and because it travels using balls, it cannot stop correctly. It's difficult. Moreover, when moving straight or changing direction at an intersection, the panel can be pushed accurately in the direction of travel.
, lkeneGJ,, the rotation of the ball (Jkima\,
The problem is that the hanging wheel cannot be moved in the desired direction.

The present invention overcomes the drawbacks of the above conventional devices and
It was developed in response to the requirements for heavy-duty panels, and opened up new prospects for the hanging and running of heavy-duty panels. That is, at the intersection, the GJ and wheel bottoms are widened to the sliding groove to enable the vertical wheels to run up to the intersection opening, and at the same time, a lower ball shaped to connect the opposing vertical wheels of the suspended vehicle is installed at the intersection wheel bottom. A groove is provided on the side of wL, and balls are placed at the intersection of the planes on the lower surface of the scarlet chassis that connects the opposing axes of the vertical wheels to the suspension wheels, and balls are also placed at the four corners of the chassis in a downward rotating manner. A ball receiving plate is suspended from the top plate at the center of the intersection, and the downwardly rotating ball is brought into contact with the upper ball groove, and the upper and lower ball grooves guide the movement of the hanging wheel. It brought about an uplift.
