Such a hanging wheel for a movable wall is provided with wheels on each of the four sides of a hanging wheel main body that is approximately square in plan view, and a hanging member for suspending the movable wall is vertically provided in the center of the hanging wheel main body, as disclosed in the same publication. As shown in FIGS. 3 and 7 fbl, the cross section is approximately C.
The hanging position of the movable wall can be changed freely by running inside the letter-shaped hanger rail.

[Problem to be Solved by the Invention] In such a conventional movable wall hanging wheel, the hanging member is suspended from the center of the hanging wheel body as described above, so the structure of the hanger rail has a cross section as described above. It has to be C-shaped.

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 disadvantage that the entire movable wall becomes expensive.

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 such as the one described above, it is necessary to consider the load balance and have sufficient strength, and from this point of view, the present invention proposes to use 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 the wall is moved.

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 vehicle travels on a running track. This hanger rail H is
It is composed of flange portions F, , F2 and a web portion W that connects both flange portions F, , F2. The left and right upper surfaces 2m and 2b of one flange F1 are used as horizontal running surfaces of the hanger rail H.

A movable wall (not shown) is suspended from 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 1 formed by flanges of a suspension wheel main body 6 made of H-shaped steel.

Three wheels 91.9b9e (left and right 16111) are rotatably attached to the inside of the vertical members 71 and 7b via brackets 8, respectively. Among the three wheels 9m, 9b, and 9c on one side, the center wheel has the largest diameter, and the wheels 9c on the left and right sides have a small diameter. Above 6 (Prisoner's wheel 9m = 9m, 9t
+, 91. ．． 9c, 9c are all installed at a height that allows them to simultaneously roll into contact with the upper surfaces 2° and 2t, which are the horizontal running surfaces of the hanger rail H.

Vertical member 7. At the upper ends of the front and rear ends of the bracket 8, which constitute a part of the brackets 8 and 7t, there are attached parts 10m and 10I that protrude toward the center of the hanging wheel I.

are formed, and the mounting portions 10□ and 1 of one bracket 8

．． , 12b are both the web part W of the hanger rail 1
This keeps the moving wall moving straight. In this case, the linear guide rails 17□ and 17
If the hanger rails [I] are attached to the lower surface of the hanger rail [I so as to be in contact with the lower guide shafts 15, the inclination of the hanging wheel 1 will be regulated, and the transportation state of the movable wall will be further stabilized. In addition, in the straight section of the movable wall, the stable running condition of the hanging wheel 1 is sufficiently maintained by the upper guide wheels 12m and 12h. 7i is omitted.

Next, with reference to FIG. 7 and FIG. 8, the bending running state of the hanging 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 181 as shown in FIG.
By connecting the ends via the rail, a curved rail can be created. Such a connecting portion 18. has the same cross-sectional shape as 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 17b are provided. As a result, the lower guide member 15 of the movable wall l, which has traveled as shown by the arrow 19, is moved to the connecting portion 18. When approaching, first it comes into contact with the outer guide rail 18. This prevents the hanging wheel 1 from tilting due to the inertial force of the moving wall, resulting in a stable running condition.6 As the hanging wheel 1 moves further in the direction shown by the arrow 19, the lower guide 15 eventually reaches the position shown by the solid line. At this point, the inner guide rail 17. The lower guide rail 15 comes into contact with the lower guide rail 15, and as it advances further, it comes into contact with the outer guide rail 17 again, thereby preventing the hanging wheel 1 from tilting.

Even in such a bending running state, the upper guide 1
Since 21 and 12b consistently contact the side surface of the web portion W of the hanger rail H, the hanging wheel 1 is guided and its inclination is prevented.

The hanger rail H is further connected to the branch hanger rail by being connected via a connecting portion as shown in FIG. In the connecting portion 18-, the web portion W
is cut out at the end portion 20 shown in FIG. 6, and only the vertical guide piece 21 is suspended from the upper flange portion F2. 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 1 is traveling along the arrow 22 in Figure @8. Here, upper guide import 12□ (
When the upper part (upper stage side) is on the right side of the web W and the connecting part 18 is bent toward the right as shown in the figure, the upper guide member 12m is connected from the web part W to the vertical guide piece 2.
1, the moving direction of the hanging wheel 1 is deflected to the right, and the hanging wheel 1 moves onto the branch hanger rail H1 as shown by an arrow 221. At this time, the left vertical member 7. cutout 23. to prevent it from interfering with the straight-ahead hanger rail H2. is formed. Here, since a guide rail 17I is attached to the inner side of the vertical guide piece 21 of the connecting portion 18b, the lower guide member 15 is attached to this guide rail 171. The tilting of the hanging wheel is prevented by making contact with the suspension wheel.

On the other hand, even when the hanging wheel is transferred from the branch side hanger rail H1 to the straight side hanger rail H via the connecting part 18, a smooth bending running state can be obtained due to the action of the 12° upper guide on the upper end side.

Next, a case will be described in which the hanging wheel is transferred from the straight-ahead hanger rail H to the straight-ahead hanger rail H2 via the connecting portion 18. In this case, the upper guide M on the upper stage side
12□ is arranged on the left side of the web part W.
It is used by changing the direction of 180 degrees. Therefore, the upper guide guide 12 on the lower stage side is arranged on the right side of the web portion W. Due to the arrangement of the upper guide guides 12m and 12+, the lower upper guide guide 12 and the hanging wheel are connected to the connecting portion 18b.
When approaching the end 20 of the vertical guide piece 21
Since it passes below the guide wheels 121 and 1
25 are no longer in contact with the web portion W and the vertical guide piece 21, and the hanging wheel 1 continues to move straight as it is, and transfers to the straight-line hanger rail H2 after 1 day at the connecting part. Right vertical member 7. The connecting portion 18b and the branching hanger rail H1 are separated by a notch 23b so as not to interfere with the hanger rail H.

A similar operation is realized when transferring from the straight-line hanger rail H1 to the straight-line hanger rail H via the connecting portion 18h.

In the above embodiment, the wheels 9. provided at the center (center of gravity) of the moving wall. has a large diameter, and its left and right wheels 9b and 9I! Since the wheel 9. has a small diameter, most of the load applied to the hanging wheel 9 is transferred to the large diameter wheel 9. When the hanging wheel changes its traveling direction, the hanging wheel can easily change its traveling direction around the central wheel 91.

In addition, as shown in the above embodiment, since the wheels 91 to 9 degrees are configured at the center and at each of the front and rear sides thereof, even when crossing the notches 23 or 23 as described above, the wheels 91 to 9 degrees are wheel 91.9, and the center wheel 9.9 of wheel 9c.
Alternatively, since the front and rear wheels 9t and 9c are always in rolling contact with the running surface of the hanger rail, the hanging wheel 1 has the notch 231.
Otherwise, the inconvenience of falling onto the suspension wheel 23b and applying a large impact to the hanging wheel 1 can be avoided.

〔Effect of the invention〕

As described above, the present invention is configured by an H-type network,
In a movable wall suspension car for an H-type hanger rail in which the left and right upper surfaces of one flange are used as the horizontal running surface of the rail, a horizontal member to which the hanging member of the movable wall is vertically attached and both ends of the horizontal member are vertical members fixed respectively;
Three wheels are arranged in parallel along the traveling direction of the hanging wheel inside both vertical members, and a total of six wheels are arranged in rolling contact with the horizontal running surface, and the center of the hanging wheel is set from the upper end of the front and rear ends of both the vertical members. The front and rear mounting parts protrude in the direction, and are installed at different levels on the left and right sides.
The upper guide ring of the needle 41II is in contact with the web of the H-shaped hanger rail, the guide rail provided on the lower surface of the flange portion having the running surface of the H-shaped rail, and the horizontal member is in contact with the web of the H-shaped hanger rail. Since this mobile wall hanging vehicle is characterized by comprising a lower guide shaft provided between the wheels and the wheels, it is possible to use inexpensive H-beam steel commercially available as hanger rails that are used in large quantities. , the price of the entire moving wall can be greatly reduced, and the left and right (3111) wheels are in rolling contact with the left and right running surfaces of the hanger rail made of H-shaped steel, respectively, and support the hanging member in a dual-supported state. The support state of the hanging wheel is extremely stable, allowing it to be transported on large moving walls.Furthermore, the web part of the hanger rail is held between the guide wheels installed at different levels on the left and right, so the tilting of the hanging wheel is prevented. In addition, since the guide wheels as described above are installed apart from each other at the front and rear of the hanging wheel, a large rotational torque is applied to the hanging wheel during bending, and the hanging wheel changes the traveling direction extremely easily. Furthermore, the guide rail provided on the lower surface of the flange portion and the lower guide rail that contacts the guide rail reliably prevents the suspended vehicle from tilting during bending, making it possible to obtain a stable running condition as a whole. .
