In such conventional movable wall hanging wheels, the hanging member is suspended from the center of the hanging wheel body as described above, so the structure of the hanger rail has to have a substantially C-shaped cross section as described above. .

The hanger rails on which the above-mentioned hanging wheels run are installed vertically and horizontally on the ceiling depending on the degree of freedom of the hanging wheels, so the unit price has a large effect on the price of the entire moving wall.

In this respect, as mentioned above, the hanger rail having a substantially C-shaped cross section has to be custom-made due to its special shape, which has the drawback of increasing the price of the entire moving wall.

From this point of view, attempts have been made in recent years to construct hanger rails using commercially available shaped steel. However, in order to suspend a large moving wall as described above, it is necessary to have sufficient strength considering the balance of r1 weight, and from this point of view, the present invention uses H-beam steel as a hanger rail. It is an object of the present invention to provide a hanging wheel for a movable wall that can exhibit sufficient strength when used.

Therefore, it is an object of the present invention to reduce the cost of the entire moving wall by using hanger rails made of H-shaped steel, which are usually commercially available, and to reduce the cost of the entire moving wall by using hanger rails made of H-shaped steel. An object of the present invention is to provide a movable wall hanging wheel with high strength.

[Means to solve the problem]

The embodiments described below are merely examples of embodying the present invention, and are not intended to limit the technical scope of the present invention.

As shown in FIG. 6, the hanging wheel l according to this embodiment has a sixth
Hanger rail H made of H-shaped steel as shown in the figure
The vehicle travels on a running track. This hanger rail H is
It is composed of flange portions F, , F, and a web portion W that connects both flange portions Fl and F2. The left and right upper surfaces 2a, 21. of one flange F. is used as the horizontal running surface of the hanger rail H.

A movable wall (not shown) is suspended on the hanging wheel 1 by hanging members 3 such as hanging bolts. The hanging member 3 is rotatably attached to a horizontal member 4, which is a component of the hanging wheel 1, by a thrust bearing 5.

Both ends of the horizontal member 4 are connected to left and right vertical members 7 formed by flanges of the suspension wheel main body 6 formed of H-shaped steel.
□, is fixed to 7b.

Vertical member 7. and 7, three wheels 9. ．． 9°59c (6 left and right hands) are each rotatably attached.

Among the three wheels 9m, 9b, and 9c on one side, the center wheel has the largest diameter, and the left and right wheels 9b, 9c have small diameters. The six wheels 9a, 9m, 9b, 9t,
9c, 9c are all mounted at a height that allows them to simultaneously roll into contact with the upper surfaces 2° and 2b of the horizontal running surface of the hanger rail H.

At the upper end of the front t&end of the bracket 8, which constitutes a part of the vertical members 7□ and 7, a portion 10. and 10 are formed, and the mounting portions 10i and 10I of one bracket 8 have shafts 11. and 10 projecting upward from the mounting portions 101 and 10I.
12. Insert the upper guide through the ．． 12. is installed. Furthermore, the mounting portions 10810 protruding from the other bracket 8 are attached to these mounting portions 10. and 10
The guide wheels 12b and 12b are respectively rotatably attached via shafts 11b and 11+ that protrude downward from the top.

Therefore, the upper guide ring 12 attached to one side of the bracket 8. and the upper guide ring 12 attached to the other bracket 8 are provided at different levels in the vertical direction. Further, the horizontal distance between the shafts 11a and 11t is set such that the upper guide wheels 12m and 12b are in rolling contact with the left and right side surfaces of the web portion W of the hanger rail H, respectively, as shown in FIG. There is.

A vertical shaft 14 is provided at the center of the web portion 13 of the hanging wheel main body 6.
A lower guide wheel 15 is rotatably attached via the lower guide wheel 15. The lower surface 16 of the hanger rail H is provided with left and right guide rails 17, to which the lower guide wheel 15 rolls in contact as necessary. , 17I.

can be installed. Only one side of the guide rails 17 and 17b may be attached as necessary.

When the above-mentioned hanging vehicle l travels along the straight hanger rail H, three vehicles on each side @91.9+,
, 9C are the flange parts FI+ of the hanger rail H, respectively.
The upper surfaces 2□ and 2I of F2 are brought into contact with each other as shown in FIG. 6, whereby the movable wall is suspended by the hanging member 3 via the hanging wheel body 6 and the horizontal member 4 attached to its lower end.
The movable wall is transported by the traveling of the hanging wheel l. At this time, the left and right upper pharynx guides 12m, 12a, 1
2+, , and 12I are both rolled into contact with the side surface of the web portion W of the hanger rail I, thereby maintaining the straight moving state of the movable wall. In this case, the linear guide rail 17
．． and 17I are attached to the lower surface of the hanger rail H so as to be in rolling contact with the lower guide wheel 15, thereby restricting the first rotation of the hanging wheel 1 and further stabilizing the transportation state of the movable wall. However, in the straight section of the movable wall, the stable running condition of the hanging wheel 1 is sufficiently maintained by the upper guide guides 12a, 12b, so the guide rails 17a, 171. is omitted.

Next, with reference to FIG. 7 and FIG. 8, the bending running state of the suspended wheel 1 and the straight running or bending running state at the branching portion will be explained.

The hanger rail H has a connecting portion 18. as shown in FIG.
By connecting the ends via the rail, a curved rail can be created. The cross-sectional shape of such a connecting portion 18m is similar to that of a normal hanger rail H, but the seventh
As shown in the figure, it differs from a normal straight-ahead hanger rail in that it is bent in an arc in its planar state. As shown in FIG. 7, a guide rail 17 is usually provided on the lower surface of the bent portion of such a hanger rail. and 171° are provided. As a result, when the lower guide wheel 15 of the movable wall I, which has traveled as shown by the arrow 19, approaches the connecting portion 18□, it first rolls into contact with the outer guide rail 18F. This prevents the hanging wheel 1 from tilting due to the inertial force of the moving wall, resulting in a stable running condition.

As the hanging wheel 1 moves further in the direction indicated by the arrow 19, the lower guide wheel 15 eventually reaches the position indicated by the solid line, where the inner guide rail 17. The lower guide wheel 15 comes into contact with the outer guide rail 17I, and as it moves further, the outer guide rail 17I comes into contact with the lower guide wheel 15.
, which prevents the hanging wheel l from tilting.

Even in such a bending running state, the upper guide 1
2. and 12I pass through and contact the side surface of the web portion W of the hanger rail H, so that the hanging wheel 1 is guided and its inclination is prevented.

The hanger rail H further includes a connecting portion 1B as shown in FIG.
By being connected via +, it is connected to the branch side hanger rail. The connecting portion 18I.

In this case, the web part W is cut out at the position of the end part 2o shown in FIG.
It hangs down from 2. Such a vertical guide piece 21 is bent in the direction of the branch rail as shown in FIG. 8, thereby making possible a special running condition as described below.

That is, let us consider the case where the hanging wheel I is traveling along the arrow 22 in FIG. Here, the upper guide wheel 12. (upper stage side) is on the right side of the web W, and in a state where the connecting portion 18 is bent toward the right as shown in the figure, the upper guide 12. is the vertical guide piece 21 from the web part W.
22. This causes the hanging wheel 1 to deflect to the right in the direction of movement of the hanging wheel 1, as indicated by the arrow 22. As shown in , the hanging wheel transfers to the branch hanger rail H. At this time, the left vertical member 7. A notch 23□ is formed so that the hanger rail 1 does not interfere with the straight-ahead hanger rail 1. Here, the guide rail 17 is attached inside the vertical guide piece 21 of the connecting portion 18I. Therefore, the lower guide rail 15 comes into contact with the guide rail 17I, thereby preventing the hanging wheel from tilting.

Conversely, even when the hanging wheel transfers from the branching side hanger rail H1 to the straight side hanger rail H via the connecting part 18b, a smooth bending running state can be obtained by the encouragement of the upper guide wheel 12° on the upper end side.

Next, a case will be described in which the hanging wheel transfers from the straight-ahead hanger rail H to the straight-ahead hanger rail H2 via the connecting portion 181°. In this case, the upper guide wheel 12 on the upper stage side. The direction of the hanging wheel I is changed by 180 degrees so that it is placed on the left side of the web part W. Therefore, the upper guide wheel 12t on the lower stage side is arranged on the right side of the web portion W. Due to the arrangement of the upper guide wheels 12m and 12b, the upper guide wheels 12 on the lower stage side are connected to the connecting portion 18b.
When approaching the end 20 of the vertical guide piece 21
Since the wheels 12m and 12b are no longer in contact with the web portion W and the vertical guide piece 21, the hanging wheel 1 continues to move straight, and the hanger for moving straight from the connecting portion 18b. At this time, the connecting portion 18I and the branching hanger rail H are separated by the notch 23 so that the vertical member 7□ on the right side in the direction of movement does not interfere with the hanger rail H. There is.

A similar operation is realized when transferring from the straight-line hanger rail H2 to the straight-line hanger rail H via the connecting portion 181°.

In the above embodiment, the wheel 91 provided at the center (center of gravity) of the movable wall has a large diameter, and the wheels 9I on the left and right sides of the wheel 91 have a large diameter.

Since wheels 9. and 9c have small diameters, most of the load applied to the hanging wheel 1 is transferred to the wheels 9. and 9c, which have large diameters. When the hanging wheel changes its traveling direction, the hanging wheel can easily change its traveling direction around the central wheel 9□.

Moreover, as shown in the above embodiment, the wheels 9. Since the notches 23.~9c are made up of the center and three pieces each on the front and rear sides, the notches 23. Or when crossing 23t, the above three wheels 9□, 91. ．． Center wheel 9 of 9C
1 or the front and rear wheels 9b and 9e are always in rolling contact with the running surface of the hanger rail, so the hanging wheel l has a notch 23
1 or 23I, and a large impact is applied to the hanging wheel 1.
