Description

[Detailed Description of the Invention] Technical Field The present invention relates to a hanging wheel for suspending and traveling (moving) a wall panel (hereinafter referred to as a panel) of a movable partition, and a technology for a traveling rail thereof, and further relates to a technique for changing the direction of the panel, particularly for changing the direction of the panel. This relates to a technology for changing direction on running rails that intersect at right angles. The panels shall be of considerable weight.

BACKGROUND TECHNOLOGY Conventionally, for hanging and running a panel, a wheel bottom is used, which has a U-shape with a downward opening in its longitudinal section, and has both open ends protruding inward at right angles, leaving a sliding groove in the center of the front end. A running rail made of oblong material is laid toward the ceiling, and the wheels of the suspended vehicle, which rotate vertically like the wheels of a cart, are placed on the bottom of the wheels, and suspension bolts are suspended from the chassis between the sliding grooves to allow the suspended vehicle to run. A suspension device with vertical wheels that is installed in the rail and connects the upper end of the panel to a suspension bolt (for example, Japanese Patent Publication No. 50-20496, Japanese Patent Publication No. 6
0-7114, Japanese Patent Publication No. 60-7116, etc.), and a horizontal wheel suspension device in which a horizontal wheel is attached directly to the suspension bolt and the panel is connected to it (for example, Japanese Publication No. 55-2).
4288 etc.).

Overall, there are the following requirements for the suspension device including the present invention. That is, stable running can be obtained and direction changes can be easily performed. Orientation is necessary to move panels to create new or eliminate partitions.

Now, the drawback of the conventional technology is that, first, it is difficult to hold the suspension bolt perpendicularly between the sliding grooves when traveling in a straight line on the traveling rail.

In other words, the vertical wheels in the former type tend to rub against or collide with the inner wall of the running rail, while the horizontal wheels in the latter type support the weight of the panel with a single point on the bottom surface of the wheel, so they meander over the bottom of the wheel. Because you will win. For this reason, in the above-mentioned inventions, efforts are made to maintain the balance of the suspended vehicle during running by making the shape of the wheel sheath in which the wheels etc. are complicated and by adding guide wheels. Good results have not yet been obtained. The main reason for this is that the suspension wheel has a high rise and is oblong in shape.

Next, regarding the direction change of the panel on the running rail,
Conventionally, in vertical wheel suspension systems, at intersections (branches), the rails are crossed with a gentle R-line, while in horizontal wheel suspension systems, the rails cross at right angles. However, arranging the running rails by crossing at right angles has many advantages, such as it is more convenient for setting up the panels and makes the ceiling surface more beautiful. has come to be used.

Its structure is that vertical wheels are attached to each of the four sides of a rectangular parallelepiped chassis.
No. 58, Actual Publication No. 61-36708, Special Publication No. 62-17
No. 062).

The present invention belongs to this type, and is a suspension device with vertical wheels and the intersections are at right angles.

At the intersection of the traveling rails, whether it is a bent intersection of the R-line or a right-angled intersection according to the present invention, the intersection is formed integrally with a continuous shape of the lower frontage with the sliding groove of the traveling rail facing down. At this point, the bottom of the wheel is cut off, and the wheel pod is expanded to create a spacious space. As a result, the wheel loses its support at the bottom of the wheel and tilts, causing the suspended vehicle to become unstable within the widened wheel sheath, causing the undercarriage and wheels to fall between the sliding grooves or collide with the inner wall of the wheel sheath. do.

Regarding the devices adopted in conventional devices to deal with such situations at intersections, we will discuss only the right-angled intersection of the vertical wheel suspension device to which the present invention relates. In this system, the suspended vehicle is supported on the running rail by large balls (steel balls) installed at the four corners of the top or bottom of the chassis, without using floating vertical wheels.

The disadvantages of this conventional device are that it is difficult to support the lower ball at the same height as the wheel bottom, or that the upper ball does not fit properly with the suspension column at the intersection. That's true. In addition, the contact between the ball and the running rail is
There is a drawback that the rotation is not smooth because the contact is at a point. In this conventional device, when running on a straight running rail, the undercarriage is formed into a wheel sheath to prevent swinging of the hanging wheel, and small horizontal wheels that rotate in relation to the rail wall are used to ensure a good running condition. However, at the intersection, the wheel sheaths expand as mentioned above, so the horizontal wheels cannot function as guides for the movement of the hanging wheel, and the panel must be pushed in the direction of movement accurately. , the ball rotates randomly, and the hanging wheel cannot be moved in the desired direction.

In addition, with balls, the bearing force of the panel is weak, and this device is not suitable for a hanging vehicle that suspends heavy panels weighing more than 100 kg, especially more than 500 kg.

In general, it can be said that the problem of running suspended panels at intersections has not yet been resolved.

The present invention meets the above-mentioned needs by creating the following means to solve the drawbacks of the above-mentioned conventional hanging wheel devices.

DISCLOSURE OF THE INVENTION That is, in the present invention, the suspension wheel is supported by the balls, and in order to cross the cut sliding groove part of the suspension wheel support and running (panel hanging and running) without tilting the chassis. The secondary wheels of the vertical wheels installed at the corners of the side sections shall be mounted on a 45-degree slope, and at the opening of the intersection, all the main wheels will be suspended on the sliding groove, and the suspended vehicle will be supported only by the secondary wheels. This enables direction changes at intersection rails.

In addition, in order to prevent the hanging wheel from swinging at the wheel sheaths and the wheel sheaths at intersections, a guide plate with a guide protrusion that circumscribes the inner wall of the traveling rail is integrally provided on the upper surface of the hanging wheel, and a ball or horizontal wheel is mounted on the guide plate. A guide wheel is provided to guide the vehicle in the guide groove of the running rail or the intersection guide groove of the intersection rail to maintain stable running.
