Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to reduce the space required during bending movement of a movable wall hanging vehicle, thereby reducing the size of the banger rail for running the hanging vehicle, and to reduce the rotation of the movable wall hanging tool with respect to the hanging vehicle. This improves performance and enables smooth bending of the moving wall.

With conventional movable walls, where the wall can be freely moved by hanging it on a hanging wheel that moves along a banger rail installed on the ceiling of a room, when passing through a cut in the banger rail, the wheels fit into the groove of this cut. In order to prevent the wheel from falling and being unable to run or receiving a large impact, two or more wheels 2 are installed on each side of the hanging wheel body 1 in a straight line as shown in Fig. 1, and if any wheel crosses the groove, Even if the load cannot be borne, the load is borne by the remaining wheels to prevent vibrations from being transmitted to the moving wall, but in this case, the straight rail 3
When the hanging wheel 1 runs on a banger rail as shown in the figure, where the curved rail 4 branches at a branching point 5, the tip 6 of the leading wheel 2a moves along a trajectory k as shown by the dashed line. In order to avoid interference between the point 6 and the side wall 7 of the banger rail, the side wall 7 must be provided on the outside along the trajectory, so the overall width of the banger rail connected to this increases and the size is increased by at least the length m. I have no choice but to use the banger rail.

However, since the movable wall travels on banger rails that are installed vertically and horizontally on the ceiling, increasing the size of the banger rails significantly increases the cost of constructing the movable wall.

For this reason, in conventional hanging wheels, the width n1 of the wheel itself, and therefore the width of the hanging wheel itself, is made as small as possible. However, since the hanging tool for hanging the moving wall is rotatably attached to the hanging wheel body, When the width is narrowed, the area of the attachment portion of the hanging tool is also narrowed, which has the drawback of impeding the rotational performance of the hanging tool.

The present invention aims to solve the above-mentioned drawbacks of the conventional hanging wheel.The hanging tool is sandwiched in the middle, and a pair of rotating main wheels are provided on the left and right sides of the hanging wheel. A pair of rotating secondary wheels is provided, and the position of the outer surface of the rotating main wheel is directed outward from the position of the outer surface of the rotating secondary wheel (on the opposite side from the center line of the hanging wheel).
By protruding to This improves the rotational performance of the hanging tool.

Next, embodiments embodying the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 2 is a plan view (including a partial sectional view) of a hanging wheel according to one embodiment, FIG. 3 is a side view of the same, FIG. 4 is a view taken in the direction of arrow I in FIG. 2, and FIG. 3, and FIG. 6, a=f, are schematic plan views showing modified examples of the hanging wheel, and FIG. 7, a=d, are plan views including the banger rail, showing running states of the hanging wheel, respectively.

2 to 5, a suspension wheel main body 11 forming the main body of the suspension wheel 10 has a vertical insertion hole 12 in the center, and a hanging tool for hanging a movable wall is inserted into the insertion hole 12. The head 14 of the hanging bolt 13, which is an example, is installed in a step 15 provided at the upper part of the insertion hole 12, and is prevented from coming out by a cover 16 screwed onto the upper part of the step 15. ing.

The side walls of the central part of the hanging wheel main body 11 constitute protrusions 17, 17 that protrude in the left and right directions, respectively.
A rotatable main wheel 19 is fitted to each of the main shafts 18 and 18 of the same window that protrudes further from 7.17, and the center line j of the main wheels 19, 19 is aligned with the center 20 of the hanging bolt 13.
is passing through.

Therefore, the axial force applied to the suspension bolt 13 is the main wheel 19.
It acts equally on 19.

Rotatable secondary wheels 22, 22 are attached to the rear side surfaces 21, 21 of the hanging wheel main body 11, and rotatable secondary wheels 24, 24 are attached to the front side surfaces 23, 23 of the hanging wheel main body 11. However, one of the four sub-wheels 24a
A disk-shaped guide collar 25 having a diameter larger than the outer diameter p of the secondary wheel 24a is integrally formed inside the secondary wheel 24a.

Among the secondary wheels provided in front or behind the main wheels provided on the left and right sides of the hanging tool, those provided with guide flanges are called guide wheels.

As shown in FIG. 2, the side surface 26 of the secondary wheel 24, etc., including the guide wheel 24a is provided inside the side surface 26' of the main wheel 19 by a distance q.

Note that 27 is a bearing for supporting the guide wheel 24a on a shaft 28 provided on the suspension wheel body 11.

Horizontal guide wheels 31 and 31' fitted into the guide grooves 30 of the banger rail are rotatably attached to the shafts 29 and 29 protruding from the lower part of the hanging wheel body 11, respectively, in order to guide the hanging wheel and prevent the hanging wheel from swinging laterally. The distance e from the centers 32 and 33 to the center 20 of the hanging bolt 13 is
1 and e2 are different, and the distance e1 on the guide wheel 24a side is shorter than the distance e2 on the other side.

Various modifications of such a hanging wheel will be explained using FIG. 6 a = f.

In both of these modifications, main wheels 1 are installed on the left and right sides of the suspension wheel body 11.
9, 19 are provided, the suspension bolt 13 center is arranged on the center line of the main wheels 19, 19, and one or more of the sub wheels provided in front or behind the main wheels are used as guide wheels. Common.

In the case of Fig. 6a, there is one subwheel 24b in front of the main wheel.
This is the case where the secondary wheel 24b also serves as the guide wheel 24a, and in the case shown in the figure, the guide wheel 24 is provided on the front right side.
Figure c shows the case where the secondary wheel 24d is placed on the rear left side, Figure C shows the case where the front guide wheel 24e and rear secondary wheel 24f are both placed on one side (right side), and Figure d shows the case where the front guide wheel 24e and the rear secondary wheel 24f are placed on the front left side. A 24g guide wheel is installed on the front right side and 2 secondary wheels are installed on the rear left side.
When 4h and 24h are installed, the figure e shows only the guide wheel 24i at the front and one subwheel 24J, 24J at the rear, one each on the left and right.
Furthermore, the figure f shows a case where a guide wheel 24kt24 is provided with a large-diameter flange 34 and a small-diameter flange 35 on the front left and right sides, respectively.
m is provided.

The figure also shows a case where two secondary wheels 24n and 24n are provided at the rear, and in both cases the main wheels protrude from the secondary wheels to the left and right sides, and the distance from the center of the suspension bolt to the guide wheel on the guiding wheel side is The distance is shorter than the distance to other guide wheels.

Next, the operation of the present invention will be explained using the hanging wheel shown in FIG. 2 as an example with reference to FIG. 7.

Figure 7 shows the behavior of the hanging wheel at the branch of the banger rail, and the banger rail 36 shown in Figure 4 is indicated by the arrow A.
This is the view from the direction of.

In the figure, 37 is the right wall of the banger rail, 38 is the left wall of the banger rail, and although the upper wall 39 in Figure 4 is omitted in Figure 7, the upper wall 3 is the same.
9, but the idle rail 40 is displayed.

In Fig. 7, such a straight portion 36a of the banger rail is shown.
The branching part between the curved part 36b and the arc-shaped bent part 36b is shown, and the above-mentioned 30 is the banger rail 3 which is a plane on which the hanging wheel 10 runs.
The guide rollers 31, 31' are loosely fitted in the guide groove provided between the bottom walls 42 and 42 of 6 and run, thereby determining the running direction of the hanging wheel and preventing the hanging wheel from swinging in the left-right direction. It is something.

Therefore, as shown in FIG. 7a, in the case of a suspended vehicle in which the guide wheel 24a is on the straight rail 36a side, the suspended vehicle 10 traveling straight in the direction of arrow B has guide wheels 31° 31' restrained by the guide groove 30 at the branching point. The guide wheel 31
However, the guide collar 25 of the guide wheel 24a is sandwiched between the guide groove 30 and the linear side surface 43 of the guide rail 40, so that it is restrained by these rails. While being moved, the hanging wheel 10 moves straight to the position 10a indicated by the broken line, and continues to move straight.

Next, as shown in FIG.
If it is on the side b, the guide wheel 24a of the hanging wheel 10 that has gone straight
Since the guide collar 25 integrated with the guide collar 25 contacts the curved side surface 45 of the guide rail 40 at a point 25a on the outer periphery of the guide collar 25 as shown in the figure, the traveling direction of the hanging wheel follows the arrow C along the side surface 45 of the guide rail. Therefore, as the guide wheel 24a continues to move forward, the guide wheel 24a is guided by the side surface 45 of the guide rail and advances to the position shown by the two-dot chain line 10b, and further bends and moves toward the next straight banger rail. I'll move on.

In this behavior of the suspended vehicle, the side wall 3 of the banger rail
7 and the secondary wheel 24 of the suspension wheel 10 is a problem, but in the above embodiment, the side surfaces 26 of the front and rear secondary wheels are retracted by a distance q from the side surface 26' of the central main wheel 19. Distance q1 from the center line r of the suspended wheel to the side surface 26 of the secondary wheel 24
is shorter by q than the distance q2 to the side surface 26' of the main wheel 19, so the radius of '' in the trajectory drawn by the outermost end of the sub-wheel becomes small, and even if the width of the side wall 37 is made small, the sub-wheel have no contact with.

Furthermore, as mentioned above, since there is a difference q in the amount of protrusion between the central main wheel 19 and the sub-wheels before and after it, the rotating sub-wheel 22°24 or 2
4a and the rotating main wheel 19 are arranged in a straight line, the width S of the protruding part 17 (see Fig. 2) to which the rotating main wheel 19 is attached is set to a sufficiently large hanging bolt head. While maintaining the wide width necessary for inserting the suspension bolt 14, the radius of curvature of the rotation locus of the rotating subwheel (see Figure 7) can be set to a small value, and the load on the hanging bolt 13 can be reduced as before. Since the area of the step portion 15 that supports the movable wall can be made large, the smooth rotation of the hanging bolt 13, which should rotate relative to the hanging wheel body 11, can be maintained while supporting the heavy load of the moving wall.

In other words, if the distance qH (see Figure 7) of the rotating secondary wheel from the center line r of the suspended wheel is the same as that of the conventional suspended wheel (shown in Figure 1), the suspended wheel will be smaller than the conventional suspended wheel. This means that it is possible to relatively increase the maximum width S of the main body, and if the maximum width S of the suspension wheel main body is increased in this way, it becomes possible to use a hanging bolt with a correspondingly larger diameter. Accordingly, the direction change of the moving wall will be performed smoothly.

On the other hand, the distance t between the center line 46 of the guide wheel 24a and the center 41 of the guide wheel 31 and the guide roller 3 described in the above embodiment
The distance between the center of 1' and the center of the hanging bolt 20 is determined as follows.

That is, the guide ring 31 determines the traveling direction of the hanging wheel by engaging with the guide groove 30, whereas the guide collar 25 controls the traveling direction by engaging with the guide rail 40. If they proceed further than the state shown in the figure and engage at the same time, their directions of movement are slightly different, and they interfere with each other, impeding smooth bending progress.

This tendency becomes more remarkable as the distance t becomes smaller, and there is almost no problem when the guide roller 31 is brought as close as possible to the hanging bolt 13 as shown in FIG.

If the above distance t is made smaller, the guide roller 31 will collide with the tip 48 of the banger rail 36 at the position shown in FIG. If the distance t is increased, that is, the distance e1 between the guide roller 31 and the hanging bolt 13 is made as small as possible, the above-mentioned problem will not occur.

Furthermore, even if the main wheel 19a shown by the two-dot chain line in FIG. 7a or the main wheel 19b shown by the two-dot chain line in FIG. Since the front and rear sub-wheels are on the hanger rail and support the load, there is no problem.

Contrary to the case shown in Fig. 7 above, as shown in Fig. 7C, the hanging wheel passes from the bending rail 36b side through the branch part to the straight rail 3.
When transferring to the 6c side, as shown in the figure, the guide wheel 24a plays almost no role, so before the branch point, the running direction is controlled exclusively by the guide wheels 31, 31' passing through the guide groove 30. However, since the width of the guide groove 30 becomes wider when the guide wheel 31' reaches the branching part, the hanging wheel 10 moves by inertia to the position 10c shown by the two-dot chain line, and the guide roller 31' moves to the side surface of the straight rail 36b. That is, it comes into contact with the guide groove 30 and changes its running direction in the direction of arrow D.

At this time, the moment for turning the hanging wheel 10 is expressed as the product of the distance U between the center 20 of the hanging bolt, which is the load center of the hanging wheel, the contact point 49 between the guide roller 31' and the guide groove 30, and the force pushing the hanging wheel. Therefore, it is desirable that the distance U is larger.

Therefore, it is desirable that the distance from the center of the hanging bolt to the center of the guide roller is also large.

As described above, in the present invention, a pair of rotating main wheels are provided on the left and right sides of the hanging wheel main body, and a movable wall hanging tool is arranged on the axis of the rotating main wheels, so that the horizontal inclination of the hanging wheel is prevented. This prevents the hanging wheel from crossing the branch of the banger rail because a pair of rotating sub-wheels are attached to the sides of the hanging wheel body before and after the rotating main wheel. When the rotating main wheel passes over the guide groove of the banger rail, the rotating secondary wheels before and after the rotating main wheel are on the banger rail and support the load of the moving wall applied to the hanging wheel body. There is no inconvenience such as the wheel falling into the guide groove and applying a large impact to the moving wall, and the main rotating wheel bears the entire load when the rotating secondary wheel passes over the guide groove.
There is no inconvenience such as the hanging wheel tilting in the front-back direction, and even in normal running conditions, the rotating main wheel and the rotating secondary wheels in front and behind it are in contact with the banger rail at the same time, so the hanging wheel does not tilt in the front-back direction and can be moved. The orderly arrangement that is the essence of a wall is achieved, and the distance from the center of the suspension wheel to the outer surface of the secondary wheel is shorter than the distance from the center of the suspension wheel to the outer surface of the main wheel. This allows us to use a small banger rail, reducing costs, and conversely, the distance from the center line of the suspension wheel to the outer surface of the secondary wheel can be made the same as that of a conventional suspension wheel as shown in Figure 1. In this case, the maximum horizontal width of the suspension wheel body can be made larger than that of conventional suspension wheels, so the mounting area of the hanging tool (hanging bolt) attached to the suspension wheel (the area of the stepped portion 15 shown in Fig. 3) can be increased. This improves the rotational performance of the hanging tool and allows the movable wall to bend and travel extremely smoothly.
