Description

[Detailed Description of the Invention] This invention relates to a technology for a hanging wheel and a running rail for suspending and running a movable partition wall panel (hereinafter referred to as a panel), and furthermore, the intersection of the running rails has a gentle R-line. The present invention relates to the technology of curved running rails that intersect with each other and the hanging wheels for curved running.

Conventionally, a hanging wheel is installed on the running rail that is laid above the room, and the panels are hung from this.The panels are moved and lined up to create a partition, and the panels are untied and the panels are hung while still hanging. The panels are gathered in one corner of the room, and the panels are stacked one on top of the other with their front panels facing each other. When the panels are housed, the orientation of the panels is changed 90 degrees, and in order for the suspended vehicle to run separately in the front and back on two parallel running rails, a curved running rail that curves with a gentle R line is installed at the intersection (branch point). There are cases where the curved running method is used, and there is a case where the running rails are crossed at right angles to each other.

The present invention relates to the former method of curved travel. Conventionally, as a suspended vehicle for curved travel, one or more sets of wheels with radial ball bearings that rotate in a vertical plane are attached to a vehicle body having an axle perpendicular to the suspension axis, and these are placed on the bottom of the wheels on the traveling rail and moved. (running), and the hanging shaft on which the panel is suspended moves through the sliding groove in the opening between the wheel bottoms.

When the suspension wheel is moved to align the panels in a row (when the traveling rails are in a straight line), the wheels with radial ball bearings are placed vertically on the bottoms of the wheels on both sides of the sliding groove. The panels can be rotated and moved smoothly, just as if a car were driving down a straight, flat, paved road.
However, in the case of an intersection where a curved running rail and a running rail intersect, for example, the direction of the panel may be changed.
When the hanging wheel moves separately towards two parallel running rails to make a 90 degree transformation,
Since the sliding grooves intersect and the wheel bottom of the curved running rail side is cut off, one wheel of the front suspension wheel traces the R line of the curved running rail and follows the connected wheel bottom. Both wheels can turn, but the other wheel will fall into the sliding groove at the intersection. At the intersection, one of the wheels of the subsequent suspended vehicle also fell into the sliding groove, and the suspended vehicle stopped moving.

For this reason, conventionally, a locking protrusion is provided at the top of the running rail, and a large secondary wheel or a secondary wheel with a flange is locked and rotated on this, or a small radial ball bearing is used as a horizontal ring to engage the protrusion. Alternatively, this horizontal wheel can also be inserted between the sliding grooves to support the whole body without tilting along with the wheels on one side, and to make it easier to guide curved travel (Special Publication No. 50-20496, Special Publication No. 20496)
No. 60-7114, Special Publication No. 60-7116, etc.) are used. These inventions also include measures to make the turning radius of wheels at intersections as small as possible, such as making the axles of the wheels and subwheels longer and the latter shorter, and placing horizontal wheels in eccentric positions. etc. have also been added.

However, a drawback of these conventional hanging wheels is that they are complex in structure. It also increases the hanging load,
In order to make curved driving more stable, the number of wheels and secondary wheels can be increased. Because of this, the car body is elongated,
The distance between the hanging shaft and the wheels also becomes longer, and stability during rotation tends to be impaired. Another drawback is that the horizontal guiding wheel supports the weight of the hanging shaft and panel at an angle at one end, making it impossible for the wheels to work perpendicularly to the plane on which they run on the bottom of the wheels. Horizontal wheels often run in a curved direction with almost no rotation. Next, in today's panel suspension, where horizontal wheels with radial ball bearings weigh more than 300 kg, the horizontal wheels used to guide the hanging wheels are often damaged, and suspension wheel breakdowns are a frequent occurrence, especially when traveling around curves. .

When radial ball bearings are not used horizontally for guidance, that is, when the large secondary wheels and secondary wheels with flanges are used, they rotate perpendicularly to the bottom of the wheel. This rotation is caused by the locking of the wheel, and is no different from the tilting bearing in the horizontal wheel, and the increased friction surface makes curved travel awkward, and radial ball bearings do not rotate sufficiently, causing damage to the secondary wheel. was even higher than the horizontal wheel.

Furthermore, in running rails and curved running rails, there has been a lack of ideas for reducing friction surfaces. In view of these drawbacks of conventional curved travel devices, the present invention eliminates the use of radial ball bearings in secondary wheels and horizontal wheels for guidance, and guides the vehicle without rotating the conical sliding surface body integrated with the vehicle body. business,
In addition, the suspension wheel has a nearly cubic shape with a small rotation radius, and the protruding locking part has an inclined surface, and a locking protrusion with a circular cross section is arranged on this to reduce the friction surface. It was created as a device for rails and curved running rails.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the present invention is a device comprising a hanging wheel 1, a traveling rail 2, and a curved traveling rail 3. All of these are made of hard materials such as metal.

As shown in FIGS. 1 to 4, the hanging wheel 1 has a rectangular parallelepiped main body 4, and an axle 7 having an axis 6a located slightly below the center of the opposing side surfaces 5, 5, at right angles to the outside of one side surface 5. Make it stick out, and almost the main body 4
Main wheel 8 of a radial ball bearing with an outer diameter of about the same height as
Attach it so that it can rotate freely. The main wheels 8 are also rotatable on the wheel bottoms 9 of the running rails 2, which will be described later.

Next, the other side surface 5 of the main body 4 is notched inwardly except for the upper part, and an axle 7 of the same shape is left in a position facing the axle 7 in the notch so as to protrude outward at a right angle. A main wheel 8 having the same shape as the main wheel 8 is attached so as to be rotatable.

Next, on the upper surface 10 of the main body 4, a hanging shaft hole 11 having a circular cross section is opened from the upper surface 10 to the lower surface 12 at the center of the rectangle excluding the upper part of the notch. The opening is further cut out and expanded into a slightly larger cylindrical shape to form a saucer portion 13. Moreover, in the upper part of the notch part of the upper surface 10 of the main body 4, a small base body 14 is vertically arranged above the cutout part.
The axis 6 of the axle 7 is projected onto the base body 14.

The surfaces 18 of the conical sliding body 17 and the base body 14 are made smooth by baking or applying a sliding agent, or by polishing. On the other hand, the saucer portion 13 of the hanging shaft hole 11
When inserting the suspension shaft 21, which has a cylindrical head 19 at the upper end of the cylindrical body 20, into the suspension shaft hole 11, as shown in FIG. A ball bearing 22 is disposed, and the cylindrical body 20 is passed through the hanging shaft hole 11 downward from the upper surface 10 of the main body 4, and the cylindrical body 20 is made to protrude from the lower surface 12. In this case, as shown in FIGS. 2 and 3, the center line 15
are the axle centers 6a, 6a of the axle 7 and the axle center 6 of the hanging shaft 21.
They are orthogonal in passing through b. That is, even in the longitudinal cross-sectional view of FIG. 1, the center line 15 connecting the axes 6a, 6a of the axles 7, 7 and the center line vertically passing through the axis 6b of the hanging shaft 21 are perpendicular to each other, and the cylindrical body 20 is the main body. The suspension wheel 1 of the present invention is rotatably fixed to the lower surface 12 of the suspension wheel 4 by a clip washer 23.

Next, as shown in FIGS. 1 and 5, the running rail 2 is made of a long member having a U-shape with a downward opening in cross section, and has both open ends protruding inward at right angles to form wheel bottoms 9, 9. However, a sliding groove 24 is open in the longitudinal direction between the opposing wheel bottoms 9, 9. Further, the center of the upper surface of the elongated member 25 is recessed inward in a V-shape in the cross section to form locking walls 26, 26. On the inner wall of the locking wall 26, a small flange protrusion 27 is vertically projected downward from the lower end of the V shape (the central part where the locking walls 26, 26 meet), and the flange tips 28, 28, which are open on both sides, are rounded. Sliding protrusions 29, 29 each having a circular cross section are protruded from the inclined surface of the locking wall 26. Further, on the inner surfaces 30, 30 of the elongated member 25, a base support 31 having a circular cross section is protruded at a position facing the flange tips 28, 28. The surfaces of the flange tip 28, the sliding protrusion 29, and the base support 31 are made smooth, and the space surrounded by the flange protrusion 27, the locking wall 26, the inner surface 30, and the wheel bottom 9 is made into a wheel sheath 32, 32. This is the traveling rail 2 of the present invention. As shown in FIGS. 6 and 7, the curved traveling rail 3 has one or both ends curved in a gentle R-line in the longitudinal direction.

Next, to describe the usage direction of the present invention having the above configuration, the relationship between the hanging wheels 1a, 1b and the traveling rail 2 and the curved traveling rail 3 is shown in FIGS. 1, 6 and 7. Running rails 2, 2... are laid above the room, and curved running rails 3 are combined to form an intersection 33. When the two hanging wheels 1a and 1b are installed inside the traveling rail 2, one hanging wheel 1a is arranged so that the conical sliding bodies 17 and 17 are housed in the wheel sheath 32 on the side A to which the curved traveling rail 3 is attached. The main wheels 8, 8 are placed on the bottoms 9, 9, and the base body 14 at the top of the main wheels is attached to the flange tip 28.
and in contact with the base support 31, and the conical sliding body 1
7 and 17 are brought into contact with the sliding protrusions 29 and 29. The hanging shaft 21 is suspended in the sliding groove 24, and the interior of one hanging wheel 1a is completed. Next, the other hanging wheel 1b is brought behind the first hanging wheel 1a, and its conical sliding body 1
7, 17 are housed in the wheel sheath 32 on the opposite side B from the first hanging wheel 1a, and the main wheels 8 are placed on the wheel bottoms 9, 9 in the same way as the first hanging wheel 1a, and the hanging shaft 21
is hung in the sliding groove 24, the base body 14 is attached to the flange tip 28 and the base body receiver 31, and the conical sliding body 1 is
7, 17 are brought into contact with the sliding protrusions 29, 29 and installed internally. A panel 34 is arranged under the hanging wheels 1a, 1b, and the hanging shafts 21, 21 of the hanging wheels 1a, 1b are rotatably attached to the front and rear ends of the upper end surface 35 of the panel 34, and attached to the traveling rail 2 of the panel 34. The hanging is completed.

In moving the hanging panel 34, the traveling rail 2
When the upper hanging wheels 1a, 1b move straight, the main wheels 8, 8,
8 and 8 rotate smoothly on the wheel bottoms 9 and 9, and A and B
The conical sliding bodies 17, 17, 17 in the wheel sheaths 32 placed in opposing positions mutually restrict the rolling of the suspended wheels 1a, 1b, and the conical bodies and the contact surface with a perfect circular cross section minimize the friction surface. Due to this smoothness, the hanging panel 34 can be moved (traveled) more smoothly than ever before. When the hanging panel 34 curves, the conical sliding bodies 17, 17 of one hanging wheel 1a lock on the locking wall 26, lose the wheel bottom 9 on the B side, and move into the sliding groove 2.
Supporting the main wheel 8 that is about to lean down and fall, the first suspended wheel 1a is advanced forward of the curved running rail 3 along the locking wall 26 that forms an R line and the first wheel bottom 9, and the other suspended wheel 1b is supported. is the intersection 33, and the wheel bottom 9 on the A side
The conical sliding bodies 17, 17 support the main wheel 8, which is about to lose its position and fall down into the sliding groove 24, at the locking wall 26, and the main wheel 8 is supported by the conical sliding bodies 17, 17, and the main wheel 8 is supported by the main wheel 8, which is about to tilt down into the sliding groove 24.
Go forward and hang panel 3 as shown in Figure 7.
4 is capable of curved driving and easily moves laterally after a 90 degree change in direction.

Furthermore, the parts of the wheel sheath 32 that accommodates the conical sliding bodies 17, 17 of the one suspension wheel 1a and the other suspension wheel 1b may be arranged in the opposite manner to that described above.

According to this explanation, when the panel 34 is suspended and moved, not only the main wheel 8 but also the sliding surface unique to the present invention, that is, the conical sliding body 17, the locking wall 26, and the base body 14 are used.
The panel 34 is supported and carried by the base support 31, etc., making the suspension movement stable.Moreover, unlike the conventional rotating body, the support guide is fixed, so the long panel 34 can be carried easily. It can withstand strong pressure such as holding the lower part and using one part of the suspension wheel as a fulcrum, and it can withstand heavy panels exceeding 500 kg.
4 shows stable bearing capacity.

In the case of curved running, in the conventional example, it was not possible to sufficiently deal with the curved wheel bottom 9 of the main wheel 8 or prevent it from rolling into the sliding groove 24, whereas the suspended vehicle 1 of the present invention is In addition to being neatly and stably housed in the wheel sheaths 32, 32 of the curved running rail 3, the conventional large secondary wheels and secondary wheels with flange are vertically rotating wheels that can fully accommodate curved wheel bottoms and curved guiding parts. On the other hand, the combination of the locking wall 26 of the inclined surface and the conical sliding body 17 of the conical body sufficiently copes with curved travel, and the locking of the conical sliding body 17 etc. to the locking wall 26 is made easier. Since it is also snug, there is no risk of the hanging wheel 1 tilting or the main wheel 8 falling into the sliding groove 24.

As described above, smooth running can be achieved by the structure of the present invention in which the frictional portions between the hanging wheel 1, the traveling rail 2, and the curved traveling rail 3 are minimized. In addition, in the present invention, the large secondary wheels, secondary wheels with flanges, and horizontal wheels of conventional radial ball bearings were supported with their rotational surfaces biased, which often led to failures, whereas the radial ball bearings It is used only for the wheels 8, 8, and is rotated in a vertical plane on the wheel bottom 9, thereby avoiding the frequent failures of the suspended wheels.
