Abstract

PURPOSE:To enable a smooth travel by forming a sash hanger with a double structure of a guide block and a travel carriage, causing the travel thereof with right and left or front and rear vertical wheels kept afloat in a straight motion, and bearing the guide block with a support vertical wheel at a crossing. CONSTITUTION:A sash hanger 1 is formed into the double structure of a guide block 6 and a travel carriage 7. In a straight travel, the sash hanger 1 is housed approximately fully in a wheel sheath and made to ravel, while one set of right and left, and front and rear wheels 16 and 16 is placed on a wheel bottom and the other set is kept afloat on a slide groove 22. At a crossing, the guide block 6 is supported with a vertical wheel 25 and all vertical wheels 16 and 16 are made afloat in sequence for travel. Furthermore, while a guide projection part 11 is being guided along a guide groove 28, the vertical wheels 16 and 16 are guided to an opposite wheel bottom, thereby enabling an escape from the crossing.

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 technology for changing the direction of the panel, particularly for changing the direction of the panel. This technology relates to direction change technology for running rails that intersect at right angles (crossing rails). The panels shall be of considerable weight.

BACKGROUND TECHNOLOGY Conventionally, for hanging and running panels, a horizontally long U-shaped cross section with a downward opening and both open ends of the horizontally long side protruded inward at right angles with a sliding groove left in the center of the end. A traveling rail with a wheel bottom is laid toward the ceiling, and the wheels of a suspended vehicle, which rotate vertically like the wheels of a cart, are placed on the wheel bottom, and the suspension shaft is suspended from the chassis at the height of the sliding groove to create a suspended vehicle. A suspension device with vertical wheels that is installed in a traveling rail and connects the upper end surface of a panel to a suspension shaft (for example, Japanese Patent Publication No. 50-20496, Japanese Patent Publication No. 1987-60)
7114, Japanese Patent Publication No. 60-7116, etc.), and horizontal wheel suspension devices (for example, Japanese Publication 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.

The drawback of the conventional technology is that, first, it is difficult to hold the hanging shaft perpendicularly between the sliding grooves when traveling in a straight line on the traveling rail. That is, the vertical wheels in the former often rub against or collide with the inner wall of the running rail, while the horizontal wheels in the latter use a single point on the underside of the wheel to create a complicated shape of the wheel sheath that accommodates the suspended vehicle. Efforts have been made to maintain the balance of the hanging wheel by increasing the weight of the suspension wheel and adding many guide wheels, but good results have not yet been obtained with regard to particularly heavy panels.

Next, regarding the direction change of the panel on the running rail,
Conventionally, vertical wheel suspension systems have been used to perform LJ, KL at intersections (branches), and curved intersections with 8 gentle curves against self-propelled rails, while horizontal wheel suspension systems have been used to perform G at intersections (branches).
'', the rails were crossed at right angles, but arranging the running rails at right angles has many advantages, such as being more convenient for setting up panels and improving the aesthetic appearance of the ceiling surface. The orthogonal crossing direction change method has also come to be used in hanging wheel systems.

Its structure is one in which hanging wheels are attached to each of the four sides of the chassis of the Tomahata body.
No. 958, Actual Publication No. 61-36708, Special Publication No. 1982-1
No. 7062).

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 running rails, whether it is the one-curve bent intersection or the curved 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 finger groove facing down. At the intersection, the bottoms of the wheels are cut off, and the wheel sheaths are expanded to create a spacious space. As a result, the wheel loses its support at the bottom of the wheel and tilts, making the suspended vehicle unstable within the widened wheel sheath, causing the chassis and wheels to fall between the sliding grooves or collide with the inner wall of the wheel sheath. .

Regarding the devices adopted in conventional devices 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. 995al or less), at intersections, do not use all vertical wheels floating, but use large balls C8 balls installed at the four corners of the top or bottom of the chassis)
This supports the hanging wheel.

The disadvantage of this conventional device is that it is difficult to support the lower ball at the same height as the wheel bottom, or it is difficult to properly align the height of the upper ball on a newly installed suspension column at the intersection. 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 wheel bottoms because the wheel bottom supports are cut off on the intersection rails as mentioned above. This is also because, as mentioned above, at the intersection, a height difference is provided in order to support the hanging wheel only with the balls and to float the left and right vertical wheels.

Note that the contact between the ball and the traveling rail is at a point, which has the disadvantage that rotation cannot be retained clearly.
In this conventional device, when suitable for running rails, the undercarriage is formed in a wheel sheath to prevent swinging of the suspended wheel, and small horizontal wheels rotating relative to the rail wall are used to improve running performance. However, at the intersection, unless the wheels and panels are pushed in the direction of travel as described above, the ball will rotate freely and the hanging wheel will not be able to move in the desired direction. Can not. Furthermore, this conventional device has the biggest drawback that it is almost impossible to stop the LL correctly at intersections.

In addition, with the ball, the load on the panel is weak, and the weight is 100Kg.
This method is not suitable for running heavy panels, especially those weighing more than 50 kg, at intersections, and it poses a serious hindrance to escaping the intersection by switching the load on the ball back to the vertical wheels. is bringing about. In general, there are many ljM points when a ball travels at an intersection, so it is difficult to consider.

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 opens up new prospects for the hanging and traveling of heavy panels in particular.

In this state, the hanging wheel 1 is housed in the wheel sheath 30 of the traveling rail 2, and when pushing the panel and rotating the left and right vertical wheels 16, it collides with the inner wall of the wheel sheath 30 as described above. There is no occurrence of wheel alignment or wheel alignment, and it is possible to obtain stable and good running in a well-balanced manner with respect to the center thread 17.

The guide stand 6 rubs against the running surface of the receiving vertical wheel 25 as it moves, causing it to rotate. Even if the receiving vertical wheel 25 supports the guide stand 6 at this angle (inclination) of 45 degrees, the rotational force and bearing force of the radial ball bearing 15 are completely unchanged from those of the vertical wheel 16.

The shape of the tip of the guide protrusion 11 is such that it fits perfectly in the planar intersection 29 and can be protruded and pressed there, so that the guide protrusion 11 does not move at the intersection opening 23 and the suspended car can be moved. 1 (hanging 1III + 1
2) can be correctly stopped at intersection 1023.

These innovations successfully solved the conventional problems, especially at rail intersections, and also paved the way for heavy panels.
