Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension vehicle for suspending and moving (moving) a movable partition wall panel (hereinafter referred to as a panel) and a traveling rail thereof, and more particularly to changing the direction of the panel. The present invention relates to a technique for changing the direction of a traveling rail that intersects at a right angle. The panel shall be of the equivalent weight class.

BACKGROUND ART Conventionally, for suspending and traveling a panel, a wheel bottom having a U-shaped vertical section with a downward opening and having both open front ends inward at right angles and a sliding groove left in the center of the front end is provided. A horizontally long running rail is laid on the ceiling, and a wheel of a suspension car that rotates vertically like a wheel of a cart is placed on the bottom of the wheel, and a suspension bolt hangs from the chassis between sliding grooves to drive the suspension car. A suspension device for a vertical wheel that is installed in a rail and connects the upper end surface of the panel to a suspension bolt (for example, Japanese Patent Publication No. 50-20496 and Japanese Patent Publication No. 6).
0-7114, Japanese Examined Patent Publication No. 60-7116, etc.) and a horizontal wheel suspension device for attaching a horizontal wheel directly to the suspension bolt and connecting the panel to the suspension wheel (for example, Japanese Utility Model Sho 55-2).
4288).

In general, the suspension vehicle device including the present invention has the following requirements. That is, it is possible to obtain stable traveling and to easily change the direction. Reorientation is necessary to move the panels to create new partitions or to eliminate them.

Now, a drawback of the conventional technique is that it is difficult to hold the suspension bolt vertically between the sliding grooves to travel straight when traveling straight on the traveling rail. That is, the vertical wheel in the former may friction or collide with the inner wall of the traveling rail, and the horizontal wheel in the latter supports the weight of the panel at one point on the bottom surface of the wheel, and therefore meanders on the bottom of the wheel. Because you will win. For this reason, in the above-mentioned invention, the shape of the wheel pod for accommodating the wheels and the like is complicated, or the addition of the guide wheel is carried out to maintain the balance of the suspension vehicle during traveling, but with regard to the heavy weight panel Has yet to get good results. The main reason for this is that the suspension vehicle has a high rising edge and has a horizontally long shape.

Next, regarding the direction change of the panel on the traveling rail,
Conventionally, in a suspension system for vertical wheels, at a crossing (branch), a curved R-line is used to make a straight intersection with respect to a straight-ahead rail, whereas in a suspension system for horizontal wheels, a right-angled crossing of rails is performed. However, the arrangement of traveling rails at right-angled intersections is more convenient for panel construction and has a better aesthetic appearance on the ceiling surface. Came to be used.

The structure is one in which vertical wheels are attached to the four side surfaces of a rectangular parallelepiped chassis (for example, Jikho Sho 61-99).
58, Jikkoku Sho 61-36708, Japanese Examined Sho 62-17
062).

The invention belongs to this type and is a suspension device for vertical wheels and the intersection is a right angle intersection.

At the intersection of the traveling rails, the traveling rail of the same shape is integrally formed in a continuous shape of a downward opening with a sliding groove at both the bending intersection of the R line and the right angle intersection according to the present invention. In the section, the wheel bottom is cut off and the wheel pod is expanded to form a wide space. As a result, the wheel that has lost its support at the bottom of the wheel tilts, and the suspended vehicle becomes unstable in the wide wheel pod, causing the chassis or wheel to fall between sliding grooves or collide with the wheel pod inner wall. To do.

Regarding the contrivance in the conventional device adopted to cope with such a situation at the intersection, only the right-angled intersection of the suspension device for the vertical wheel related to the present invention will be described. Instead of floating the vertical wheels, the suspension vehicle is supported on the traveling rail by large balls (steel balls) provided at the four corners above or below the chassis.

The disadvantage of this prior art device is that it is difficult to support the lower ball at the same height as the wheel bottom, or the upper ball does not fit well with the suspension post at the intersection. Is. The contact between the ball and the traveling rail is
There is a defect that the contact is at a point and the rotation is not smooth. In this conventional device, when traveling straight on a traveling rail, the chassis is formed in one of the wheel pods to prevent swinging of the suspended vehicle, and small horizontal wheels that rotate in relation to the rail wall are used to achieve a good traveling condition. However, since the wheel sheath spreads at the intersection as described above, the role of the horizontal wheel that guides the progress of the suspension vehicle is no longer valid and the panel must be accurately pressed in the traveling direction. However, the rotation of the ball is inconsistent, and the suspension vehicle cannot be advanced in the intended direction.

Also, with balls, the load on the panel is weak, and for a suspension vehicle that suspends a heavy-weight panel of 100 kg or more, particularly 500 kg or more,
This device is not suitable.

In general, it can be said that the difficulty of running the suspension panel at the intersection has not been solved yet.

The present invention meets the above-mentioned needs by creating the following means for solving the above-mentioned drawbacks of the conventional suspension vehicle device.

DISCLOSURE OF THE INVENTION That is, according to the present invention, the support of the suspension vehicle by the ball is eliminated, and the main wheel and the auxiliary wheel of the vertical wheel having a strong burden in the vertical direction are used for the support and traveling of the suspension vehicle (suspension of the panel, traveling). In order to use only wheels and to cross the sliding groove cut at the intersection rail without tilting the chassis, the auxiliary wheel of the vertical wheel provided at the corner of the side surface of the chassis is 45 degrees. All the main wheels will not float above the sliding groove at the intersection opening, and the suspension wheels will be supported only by the auxiliary wheels to enable the direction change at the intersection rails.

In addition, in order to prevent the suspension car from swinging at the wheel shed and at the intersection wheel shed, a guide plate with a guide protrusion that contacts the inner wall of the traveling rail is integrally provided on the upper surface of the suspension car, and a ball or horizontal wheel is provided on the guide plate. The guide wheels are provided to guide in the guide groove of the traveling rail or the intersection guide groove of the intersection rail to keep the traveling stable.

The above is the structure of the intersection rail 3.

The suspension running device 40 for a panel according to the present invention is the suspension vehicle 1,
It comprises a traveling rail 2 and an intersection rail 3.

Next, with reference to all the drawings, in particular, FIGS. 3 to 6 and 9 to 11, the use and effect of the panel suspension running device 40 of the present invention will be described.

The state in which the suspension vehicle 1 is incorporated into the traveling rail 2 is shown in FIG. 3 (type A above) and FIG. 9 (type B above).
Further, the assembled state on the intersection rail 3 is shown in FIGS. 4 (A type) and 10 (B type).

First, the traveling rails 2, 2, ...
Are laid down at right angles in the vertical and horizontal directions with the openings facing downwards, and at the intersection, they are connected to each other by arranging the intersection rails 3, 3, ... Adjacent to each other or butt (for example, sliding grooves 25, 25). Fix it.

As shown in FIG. 3 and FIG. 9, the suspension vehicle 1 is brought into the wheel pod 27 of the traveling rail 2 and the left and right main wheels 1
3, 13 and all the auxiliary wheels 14, 14 ... Are placed on the wheel bottoms 26, 26, the front and rear main wheels 13, 13 are floated on the sliding groove 25, and the guide wheel 16 or the guide protrusion 8 is set in the guide groove 29. Or, along the inner wall of the side portion 24, the hanging bolt 2
1 is hung from between the sliding grooves 25, and the suspension bolts 21 of the two suspension wheels 1 and 1 are attached to the front and rear portions (not shown) of the upper end surface of the panel.
21 are rotatably connected to each other to suspend the panel.

In this state, as shown in the figure, the suspension vehicle 1 is almost housed in the wheel sheath 27 of the traveling rail 2 and pushes the panel to move the left and right main wheels 13, 13 and the auxiliary wheel 14, When rotating 14 ..., As described above, the wheel sheath 27 does not collide with the inner wall of the wheel sheath or the wheel disengages at all, and a well-balanced and stable running can be obtained with respect to the center line 22. The auxiliary wheel 14 traveling on the wheel bottom 26 with an inclination of forty-five degrees is slightly inferior to the rotational force of the main wheel 13 but continues to rotate due to the inertia of the progress, and the burden force of the main wheel 13 and the running force are exerted. Assist power. Both the main wheels 13 and the auxiliary wheels 14 are vertical wheels, and can sufficiently withstand the suspended running of heavy class panels such as 1t and 5t. Although one auxiliary wheel 14 in the embodiment has a bearing force of 500 kg or more, a required panel bearing force can be obtained by increasing the diameters of the main wheel 13 and the auxiliary wheel 14. The suspension vehicle 1 does not have a length or a horizontally long shape, and the shape of the traveling rail 2 is simple and reasonable.

Next, when this hanging panel is advanced to the intersection rail 3, as shown in FIG. 6, the front and rear main wheels 13 and 13 proceed while being floated on the sliding groove 25 at the intersection, While supporting the suspension vehicle 1 on the wheel bottom 26 by the left and right main wheels 13, 13 and the front or rear auxiliary wheels 14, 14, the sliding groove 25 on the side of the wheel bottom 26, which is cut, is passed over the suspension bolt 21. The guide wheel 16 is positioned at the intersection opening 33, and at the same time, the guide wheel 16 is guided by the intersection guide groove 36 and guided to the plane intersection 37, and the suspension vehicle 1 reaches the intersection opening 33. During this time, the left and right main wheels 13, 13 and the auxiliary wheels 14, 14, ... Of the suspension vehicle 1 are on the wheel bottom 26 of the intersection that is completely the same as the wheel bottom 26 of the traveling rail 2, and the chassis 4 is slightly raised or lowered. The chassis 4 does not incline even when the sliding groove 25 is passed over as described above without swinging. Further, even in the widened intersection wheel sheath 34, the intersection guide groove 3 is formed.
6 by guiding the guide wheel 16 to the main wheel 1
3 and the auxiliary wheel 14 are correctly advanced, and the suspension vehicle 1 is opened at the intersection opening 3
You can lead to 3. The situation is shown in Figs. 5 and 1.
It can be seen in Figure 1. FIG. 5 shows the guide wheel 16 of the type a, the guide groove 29, and the intersection guide groove 36. The smooth curved surface formation of the corner upper end surface portion 38 of the plane intersection 37 of the intersection guide groove 36 is Intersection opening 3
The purpose of this is to more easily guide the progress when the suspension vehicle 1 is further advanced from 3.

Now, even when the suspension vehicle 1 reaching the intersection opening 33 is moved straight in the same direction or at a right angle, the main wheel of the vertical wheel has a strong gravity bearing force and rotational force. 13 and 13 are wheel bottoms 26 and 2 in the respective directions.
6 is located close to and directly faces 6, and in the case of straight traveling, the left and right main wheels 13, 13 and auxiliary wheels 14, 14 ... 14, 14
Is placed on the wheel bottoms 26, 26 and, at the same time, is guided by the intersection guide grooves 36, 36, travels across the sliding groove 25, and passes through the intersection accurately and safely.

The guide protrusion 8 in the type A of the suspension vehicle 1 is a device for supporting the suspension vehicle 1 on the wheel pod 27 of the traveling rail 2 and the inner wall of the traveling rail 2 so as to provide stability. Further, the guide protrusion 8 of the auxiliary wheel 14 together with the guide wheel 16 of the ball 18 is provided. It is a device for restricting the traveling in the same direction as the main wheel 13, and the device of the guide wheel 16 of the horizontal wheel 19 of the guide protrusion 8 in the B type of the suspension vehicle 1 has one function of the A type. It was made to double as.

In the present invention, mainly by devising the auxiliary wheel 14 of the vertical wheel which is attached to the corner portion 7 of the chassis 4 at an angle of 45 degrees to the suspension vehicle 1, all the drawbacks of the conventional device are eliminated, and particularly the weight is reduced. It opened up new prospects for suspended running of class panels.
