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 panel shall be of a considerable weight class.

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, placed on the bottom of the wheel of a suspended vehicle that rotates vertically like the wheels of a cart, and the hanging shaft is suspended from the chassis between the sliding grooves to allow the suspended vehicle to be placed inside the traveling rail. A hanging wheel system with vertical wheels that connects the upper end of the panel to a hanging shaft (for example, Japanese Patent Publication No. 50-20496, Japanese Patent Publication No. 60-7114)
), and a horizontal wheel suspension device in which a horizontal wheel is attached directly to the suspension shaft and the panel is connected to it (for example, Utility Model No. 55-242).
No. 88, 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, when traveling in a straight line on a running rail, it is difficult to hold the hanging shaft perpendicularly between the sliding grooves. 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 inventions, etc., the shape of the wheel sheath that houses the wheel is made complicated,
Efforts have been made to maintain the balance of the hanging wheel during running by adding a guide shaft, but good results have not yet been obtained, especially for heavy panels. The main reason for this is
This is because the hanging wheel has a long standing height and a horizontally long 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 by 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 panels and improves the aesthetic appearance of the ceiling surface, so even in the case of vertical wheel suspension equipment, the direction change method by crossing at right angles is recommended. 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, Jikko No. 61-36708.

Special Publication No. 62-17062).

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

At the intersection of running rails, whether it is a bent intersection of the R-line or a right-angled intersection according to the present invention, the running rails of the same shape are integrally formed in a continuous shape with a downward opening with the sliding groove 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 wheels that have lost their support at the bottom of the wheels tilt and the suspended vehicle becomes unstable within the widened wheel sheath at the intersection, causing the undercarriage and wheels to fall between the sliding grooves or collide with the inner wall of the wheel sheath. or

Regarding the devices of conventional devices adopted to deal with such situations at intersections, we will discuss only the right-angled intersection of vertical wheel suspension devices to which the present invention relates. 9958 and below), at intersections, instead of using floating vertical wheels, large balls (steel balls) installed at the four corners of the top or bottom of the chassis are used.
It supports the hanging wheel.

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 well with the suspension column at the intersection. be. 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 wheel bottoms, but on the intersection rails, because the supports on the wheel bottoms have been cut off as mentioned above. To become.

Note that the contact between the ball and the traveling rail is at a point, which has the disadvantage that rotation cannot be made smoothly. In this conventional device, when the running rail moves straight, the chassis is formed into a wheel sheath to prevent swinging of the hanging wheel, and small horizontal wheels that rotate against the rail wall are used to ensure good running. However, since the wheel sheaths at the intersection are wider than the wheel sheaths on the traveling rail, the role of the horizontal wheels to guide the movement of the suspended vehicle is no longer fulfilled, and the panel is accurately moved in the direction of travel. If the ball is not pushed, the ball will rotate freely and the hanging wheel will not be able to move in the desired direction.

In addition, with the ball, the load on the panel is weak, and this method is not suitable for running heavy panels weighing more than 100 kg, especially over 500 kg, at intersections. There is a serious drawback in escaping the intersection by switching to the burden of in general,
It is thought that there are many difficulties in running the ball at intersections.

The present invention has been made in response to the above-mentioned needs and eliminates the drawbacks of the conventional hanging wheel devices as described above, and has opened up new prospects for the hanging and traveling of heavy panels in particular.

DISCLOSURE OF THE INVENTION The present invention does not use the above-mentioned balls for a suspended vehicle, etc., and when the suspended vehicle moves straight on a running rail, a rectangular parallelepiped chassis and vertical wheels are housed in a sea pie in the wheel sheath, and two are attached to the side of the chassis. Of the vertical wheels, the left and right vertical wheels are placed on the wheel bottoms, the front and rear vertical wheels are suspended above the lower supports, and horizontal wheels and guide protrusions are provided at the four corners of the upper part of the chassis to guide them. It travels along the grooves and guide protruding grooves, and in the general shape of the running rail that intersects vertically and horizontally at right angles, the cross under bearing is flush with the bottom of the wheel. On the intersection rail placed off the axis, place the front two floating vertical wheels of the suspension wheel on the turntable, then place the left and right vertical wheels on the turntable, and then place the top plate of the intersection rail. The horizontal wheels and guide protrusions are guided through the guide grooves and guide protrusion grooves provided in the cutouts, and the vehicle gradually reaches the intersection opening.

At the intersection opening, all vertical wheels are placed on the turntable,
In the direction change of going straight or turning at a right angle, the left and right or front and rear vertical wheels on the turntable are sequentially placed on the opposing wheel bottoms, and the vehicle escapes from the intersection by being guided by the guide grooves and guide protrusion grooves. It is something.
