に、他側壁中央部内面板６を設けている。b. Prior Art There is a device according to Japanese Utility Model Publication No. 55-24288 shown in Fig. 3 as a hanging door car for a movable partition wall that changes direction at right angles on a traveling rail provided with cross-shaped intersection points.
In other words, it has a long box-shaped cross section, and in the longitudinal direction of the bottom center,
It has a small-diameter opening 4 into which the support shaft 3 of the hanging door wheel runs loosely, and an inclined protrusion 5 of the upper roller 1 mounted on the upper end of the support shaft is provided protruding in the longitudinal direction of the central part of the inner surface of one side wall. At the same time, the inner bottom surface of the inner bottom plate 7 of the other side wall is formed into an inclined inner bottom surface 7a with a cross section symmetrical with the inclined protrusion 5, with a straight downward inward direction, and a lower roller wheel 2 is mounted on a support shaft below the upper roller wheel. It is in contact only with the outer periphery of the bottom surface. In addition, some design changes were made when the idea was put into practical use. That is, an inner surface plate 6 at the center of the other side wall is provided opposite to the inclined protrusion 5 in the longitudinal direction of the inner surface of the other side wall, as shown by a dashed line.

In the modified hanging door vehicle, the upper roller 1 comes into surface contact with the inner surface plate 6 of the center portion of the other side wall facing the inclined ridge 5, making it impossible to run. Furthermore, when the hanging door wheel enters the cross-shaped intersection, the length of one side of the box-shaped square is 1, whereas the length in the diagonal direction at the cross-shaped intersection is √2, so the upper roller 1 There is a risk that the lower roller wheel 2 may separate from the inclined protrusion 5 and the inclined inner bottom surface 7a and fall down, and both roller wheels may fall lower than their normal positions, causing the support shaft 3 to swing sideways and cause the small diameter opening 4 to fall.
The movable partition wall must be moved with a very strong force in order to collide with the side wall of the intersecting point, and fine powder produced by friction falls near the intersection point. In order to avoid such a problem, the design is changed as described above and an inner surface plate 6 is provided at the center of the other side wall, but even with this approach, both wheels fall down at the intersection point, resulting in a difference in height between the lower surfaces of the wheels. The upper surfaces of the inclined protrusions 5 and the inclined inner bottom surface 7a need to be removed so that they are at the level of the other side center inner surface plate 6 and the other side wall inner bottom plate 7, which have a lower surface area. Since the load is supported by the lower end of each wheel, this part often breaks, and the box-shaped structure requires a large amount of material and processing time, resulting in high production costs.

吊下する諸装置に活用できるものである。"Effects of the Invention" Since the present invention is constructed as described above, the load of the movable partition wall is supported in the direction of the vertical axis r of the lower roller 9, so it is strong against moment and shear.
Furthermore, since the distance L between the core of the suspension bolt 10 and the core of the lower ridge 16 is very short, the lower roller wheel 9 is less likely to be destroyed. In addition, since the load is supported by almost the entire hemisphere of the lower wheel 9, it is easy to rotate. Also upper wheel 8
The upper ridge 18 supports the centering direction of the horizontal axis R, and the guide bearing 12 supports the guide wall 15.
Since the hanging door roller comes into contact with the movable partition wall, the movable partition wall can be moved stably without the hanging door wheel swinging sideways. In addition, since the lower rollers 9 are formed flat in the direction of the vertical axis r, the distance from the lower inner wall of the running rail 17 is sufficiently long, so even if a heavy load is applied, the entire lower surface of the lower rollers 9 does not come into contact with each other. Therefore, the hanging door wheel does not become unable to rotate. Further, since each of the hanging door wheels is formed into a spherical shape with a hemispherical body maintaining a gap between its flat surfaces, it can smoothly contact the lower ridge 16 and the upper ridge 18 and roll easily. At the intersection point, the lower ridges 16 are brought into contact with each other by protruding, so that the lower rolling wheels 9 can transfer to the empty space without rails formed within the intersection point without falling, and the lower rolling wheels 9 can move in the empty space without falling. Ring 9 and inferior ridge 1
Even if the contact level with 6 is slightly lower than the normal position, the lower surface of the lower roller 9 is formed to be slightly flat, so the lower roller 9 does not descend excessively, and therefore passes through the intersection point smoothly. You can do this without being shot. Further, although the present invention has been described as being for a movable partition wall, it is not limited thereto, and can be applied to various devices suspended from a ceiling rail such as an overhead traveling crane.

このように本考案は構造は堅牢で耐久性に富む
と共に製作容易な有用考案である。 As described above, the present invention is a useful device that has a strong and durable structure and is easy to manufacture.
