Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging wheel for a movable wall that has improved bending running performance and stable running performance, as well as a significant cost reduction by downsizing the hanger rail.
This project succeeded in easily bending a hanging wheel that suspends a moving wall weighing more than a ton.

In order to bend a so-called movable wall that can be freely moved by hanging a wall on a hanging wheel that moves along a hanger rail installed on the ceiling of a room, (Refer to Japanese Unexamined Patent Publication No. 54-56232), (Refer to Japanese Utility Model Publication No. 51-51568) However, in the case of (2), the mechanism that allows the hanging wheel to bend itself is complicated and requires many bearings, making it expensive, and the bending part bends and causes shock when passing through the cut in the hanger rail. There are drawbacks that cause problems such as.

In the case of ■, there is a rotation direction plate that acts as a guide on the inside of the drive wheel that carries the load, so the distance between the center of rotation and the rotation direction plate is short. Moreover, since the rotation direction plate is rotatable independently from the drive mechanism, even if the drive wheel rotates due to the movement of the hanging wheel, the rotation direction plate contacts the hanger rail and does not rotate. However, there is a drawback that the hanging wheel gets strained against the hanger rail, preventing smooth rotation and movement of the hanging wheel. The poor bending performance of such hanging wheels is due to
The larger the number of wheels that support a hanging wheel, the more difficult it is to make it bend, especially in the case of a hanging wheel that has three or more rows of wheels to smoothly cross the cut in the hanger rail.
In addition, there is a crane truck described in Tokukan Sho 51-112055 as an example in which wheels are arranged in three rows and collars are provided on the front and rear wheels. It is clear that the guard is intended to prevent a bogie that runs only on straight rails from coming off the straight rails, and is not intended for curved travel.

That is, a truck 50 as shown in FIG. 7 has three pairs of wheels 51a, 51b, 52a, 52b and 53a, 53b attached to three parallel shafts 54, 55, 56, and a bent rail 57 ( 57a and 57b)).

Flanges 58a and 59a are attached to the front and rear wheels 51a and 53a, and are caused to interfere with the end green 60a of the rail 57a to allow the rail 57a to travel in a curved manner. In this case, in order to smoothly interfere with the flange 58a and the end edge 68a, the shaft 54 supporting the wheel 51a to which the flange 58a is attached should be
Pointing in the direction of the radius of curvature at the contact portion 61a with 0a, that is, the arc-shaped end green 6Q at the contact portion 618
When the direction of the tangential line of a matches the direction of travel of the wheels 51a (the direction indicated by the arrow x), the smoothest interference can be obtained, and the direction of the cart 5 can be changed smoothly.

On the other hand, as shown by the machine edge 60b indicated by a two-dot chain line in the figure, the direction of the tangent to the edge green 60b at the contact portion 61a and the traveling direction of the wheel 5 a (perpendicular to the axis 54) (indicated by the arrow x) If there is a large difference between the flange 58a and the edge 60b, the collar 58a will bite into the edge 60b, creating a large frictional force. Particularly in the case of a hanging wheel that receives a large load from a moving wall, the frictional force between the wheel and the seal is large, and the wheel will not easily slip, preventing bending becomes impossible.

In this regard, when the front and rear wheels of the wheels arranged in three rows as shown in Fig. 7 are provided with flanges,
On a curved rail, if you try to make a smooth curved run by pointing the collar 58a of one wheel 51a toward the tangent to the edge 60a of the rail 57a with which it comes into contact, the rear wheel 53a will move as shown in the drawing. It comes off the edge 60a and becomes unable to travel.

Also, if the edge green is interfered so that it comes to the position 60b shown by the two-dot chain line, both the front and rear wheels 51a and 53a will be attached to the rail 5.
7a above ~ Each guard 58a and 59b are both on the edge 60b
However, since the direction of each collar 58a, 59b (same as the direction of travel) is significantly different from the direction of the tangent to the edge 60b,
The collar 58a or 59b digs into the edge 60M, making it impossible to run.

In order to prevent such inconvenience, it is necessary to make the radius of curvature of the rail 57 very large. In this case, the space for installing the hanger rail is limited, and increasing the radius of curvature would be a fatal flaw.

In this way, with a bogie that has flanges on both the front and rear wheels, such as the one described in Tsubakibatsu Publication No. 51-112055, it is impossible to make a bend in a small radius, and it is impossible to make a bend in a very large radius. It is understood that the vehicle is intended only for straight-line driving.

At the same time, a wheel with coins is attached to the wheel 5 provided at the front of the cart.
If it is attached only to either the wheel 1a or the wheel 53a provided at the rear, the above problem does not occur,
It is understood that by aligning the direction of the tsuba with the direction of the tangent to the end green, smooth bending can be achieved. The present invention aims to eliminate the shortcomings and inconveniences of conventional traveling control devices for moving walls such as those of the higher class. , a movable wall hanging tool is arranged on the axis of the rotating main wheel, a pair of rotating sub-wheels are attached to the sides of the hanging wheel body before and after the rotating main wheel, and one of the rotating main wheels is installed. The main rotating wheel is rotated to a position where the outer surface of the main rotating wheel protrudes outward from the outer surface of the rotating main wheel adjacent to the rotating main wheel. Attach the main wheel, and install one guide ring each, which is inserted into the guide groove of the hanger rail and guides the hanger body along the hanger rail, at a position eccentric to the front and back from the movable wall hanging device at the bottom of the hanger. The present invention provides a movable wall hanging wheel with a guiding wheel.

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

Here, FIG. 1 is a plan view (including a partial sectional view) of a hanging wheel according to one embodiment, FIG. 2 is a side view of the same, FIG. 2, FIGS. 5 a to 5 e are plan views showing various modifications of the hanging wheel according to the invention, and FIGS. 6 a to d are plan views including a hanger rail showing running states of the hanging wheel. It is. 1 to 4, a suspension wheel main body 2 forming the main body of the suspension wheel 1 has a vertical insertion opening 3 in the center, and a hanging tool for hanging a movable wall is inserted into the insertion opening 3. The head 5 of the hanging bolt 4, which is an example, is installed in a step 6 provided at the upper part of the insertion hole 3, and is prevented from slipping out by a lid 7 hinged to the upper part of the step 6. There is.

The side walls of the hanging wheel main body 2 have protruding parts 8, 8 that protrude in the left and right directions, respectively, and concentric main shafts 9, 9 that protrude further from the protruding parts 8, 8 have rotatable shafts, respectively. The main wheel 10 is iron-mounted, and the center line 11 of the main wheels 10, 10 is far from the center 12 of the hanging bolt 4.
Therefore, the force in the koji direction applied to the hanging bolt 4 is the main theory 10,1
It acts equally on 0. Rear side surfaces 13, 13 of the hanging wheel body 2
Rotatable sub-wheels 14a, 14b are attached to the suspension wheel body 2, and rotatable sub-wheels 14c, 14d are also attached to the front side surfaces 15, 15 of the suspension wheel main body 2. On the inside of one of the rings 14d, a disc-shaped guide collar 16 larger than the outer ring d of the Toyama ring 14d is integrally formed with the LiuRon 14d. Among the lily 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. Law wheel 1 including the above Derivation 14d
The side surfaces 17 such as 4a are the side surfaces 1 of the main wheel 10 as shown in the figure.
8 by an interval of 1. Reference numeral 19 denotes a bearing for supporting the shaft 2M provided on the suspension wheel body 2 to support the lead 14d. A pith 2 protruding from the lower part of the hanging wheel body 2
1 and 22 are rotatably provided with horizontal guides 24 and 25 inserted into the guide groove 23 of the hanger rail in order to guide the hanging wheel and prevent the hanging wheel from lateral vibration, respectively. From 27 to center 1 of hanging bolt 4
The distances up to 2 and n4 are different, and the distance L on the guide wheel 14d side is shorter than the other distance. Various modifications of such a hanging wheel will be explained using FIGS. 5a to 5e.

In each of these modified examples, main wheels 10 are installed on the left and right sides of the suspension wheel body 2.
, 10 are provided, the center of the hanging bolt 4 is placed on the center line of the main wheels 0, 10, and one or more of the wheels provided in front or behind the main wheels are used as guide wheels. Common.
In the case of Fig. 5a, there is one Liu ring 14e in front of the main shaft.
This is the case where the secondary wheel 14e also serves as the guide wheel 14d, and in the case shown in Figure b, the guide wheel 14 is provided on the front right side.
Figure d shows the case where the Liu wheel 14f is placed on the rear left side, Figure c shows the case where the front guide wheel 14d and rear Liu wheel 14g are both placed on one side (right side), and Figure d shows the case where the Liu wheel 14f is placed on the front left side. In the case where the front right wheel 14d is installed on the front right side and the rear left side wheels 14h and 14i are installed, respectively, the figure e shows only the front wheel 14d and the rear wheels 14i and 14i are installed on the left and right sides respectively.
4i is installed; in both cases, the main wheel protrudes laterally from the secondary wheel, and the distance from the center of the hanging bolt to the guide wheel on the lead side is longer than the distance to the other guide wheels. short. Next, the operation of the present invention will be explained using the suspension wheel shown in FIG. 1 as an example with reference to FIG. 6.

Figure 6 shows the behavior of the hanging wheel at the branching part of the hanger rail, and the hanger rail 28 shown in Figure 3 is indicated by the arrow A.
This is the view from the direction of. In the figure, 29 is the right wall of the hanger rail, 30 is the left wall of the hanger rail, and although the upper wall 31 in FIG. 3 is omitted in FIG. 6, the guide rail 32 fixed to the upper wall 31 is shown. In FIG. 6, the branching part between the straight part 28a and the arcuate bent part 28b of the hanger rail is shown. The guide groove provided in between allows the guide shaft 24 and the like to travel with loose iron, thereby determining the running direction of the suspended wheel and preventing the hanging wheel from swinging in the left-right direction. Therefore, as shown in FIG. 6a, in the case of a suspended vehicle in which the guide 14d is on the straight rail 28a side, the suspended vehicle 1 traveling straight in the direction of arrow B is released from the restraint of the guide groove 23 at the branching portion of the guide wheel 24. Therefore, the direction control function by the guide theory 24 is lost, but instead, the guide number 16 of the guide theory 14d is sandwiched between the guide groove 23 and the linear side surface 34 of the guide rail 32, so that these The hanging wheel 1 moves straight while being restrained by the rails, moves to the position la indicated by the two-dot chain line, and continues to run straight.

Next, as shown in FIG.
b, the guide collar turtle 6, which is integrated with the guiding wheel 14d of the hanging wheel l that has gone straight, touches the curved side surface 3 of the toggle rail 32 at a point 35 on the outer periphery of the guide collar 16, as shown in the figure.
4', the traveling direction of the hanging wheel is twisted in the direction of C along the side surface 34' of the guide rail, and therefore, as it continues to advance, the guide rod 4d is guided by the side surface 34' of the guide rail. Proceed to the level indicated by the chain double-dashed line lb,
The train then curved further and moved towards the next straight eight-person rail.

At this time, the center line 37 of the guide wheel 4d and the center 3 of the guide wheel 24
8 and the distance from the center of the hanging bolt to the center of the guide rod 25 are determined as follows. That is,
The guide ring 24 determines the traveling direction of the hanging wheel through engagement with the guide groove 23, whereas the guide collar 16G controls the traveling direction through engagement with the guide rail 32. If the two engage at the same time after progressing further than the state of , their respective advancing directions will be slightly reversed, and they will interfere with each other, impairing the smooth progression of bending.This tendency becomes more pronounced as the distance n becomes smaller. There is almost no problem if the guide wheel 24 is placed as close as possible to the hanging bolt as shown in Fig. 6b.Also, if the above distance n is made small,
In the position shown in FIG. 6d (n, base 0), the guide wheel 24 collides with the tip of the tongue portion 39 of the Hangacho rail 28, which again impedes smooth running, but the above embodiment In other words, the distance n is increased as shown in FIG.
The above-mentioned problem will not occur if the distance between the suspension bolts 4 and ring vine o
Even if b separates from the hanger rail when crossing the guide groove 23 at the branch, no problem will occur because the front and rear wheels are on the hanger rail and support the load. Also, contrary to the case shown in FIG. 6b, as shown in FIG.
When transferring to the side, as shown in the figure, the guiding mechanism 4d plays almost no role, so before the branch point, the running direction is controlled exclusively by the guiding mechanisms 24 and 25 passing through the guide groove 23. When the guide wheel 25 reaches the branch, the inside of the guide groove 23 becomes wider, so that the hanging wheel 1
moves by inertia to the position lc shown by the two-dot chain line, and the guide wheel 25 moves to the side surface of the straight rail 28a, that is, the guide groove 32.
The moment of turning the hanging wheel 1 at this time is generated by the contact point between the center rod 2 of the hanging bolt, which is the center of load of the hanging wheel, the guide wheel 25, and the side surface 32. 40 and the force pushing the suspension wheel, it is desirable that the distance be larger. Therefore, the distance ratio between the center of the suspension bolt 2 and the center of the guide loaf 25 is also determined to be large. Side wall 2 of hanger rail 28
9 and the toyama ring of the hanging wheel 1 has always been a problem, and in the past, it was necessary to make the inside of the hanger rail wider because the front and rearmost sub wheels 14a and 14b hit the side wall when the hanging wheel turned at the branching part. As described in the above embodiment, since the side surfaces of the front and rear Liu wheels 14a, etc., are retracted from the side surfaces of the central main wheel 10 by a distance of 1, the corners of the secondary wheels 14a, etc. are recessed by a distance of 1. Wealth through the inner trajectory. The interference between the ring and the side wall has been eliminated. Moreover, if the distance between the hanging bolt and the guide wheel is set to be large as described above, the guide wheel 26 will hit the side surface 32 of the straight rail 28a and change the running direction of the hanging wheel before the Tomiyama tortoise 4b approaches the side wall 29. Interference between the secondary wheel and the side wall is eliminated. Furthermore, as mentioned above, since there is a difference of 1 in the amount of protrusion between the main rod 10 in the center and the regular wheels before and after it, the width e of the central crest of the suspension wheel body 2 becomes wider, and the head of the suspension bolt is made wider. Since the area of the supporting step fleas is large, the rotation of the rare bolt 4, which should rotate relative to the hanging wheel body 2 while supporting the heavy load of the moving wall, becomes smooth, and the direction change of the moving wall is also performed smoothly. As described above, the present invention has a pair of rotating main wheels on the left and right sides of the main body of the hanging wheel, and a hanging tool is arranged on the bag core of the main rotating wheels. Shaking is completely prevented and the load of the constantly moving wall is applied to the left and right rotating main wheels, so they can receive a large load and the running condition is extremely stable. An essential component is that a pair of rotating wheels are attached to each of the wheels. The rotating sub-wheels before and after the main rotating wheel are on the hanger rail and support the load of the moving wall applied to the main body of the hanging wheel, so there is no possibility that the main rotating wheel may fall into the guide groove and apply a large impact to the moving wall. There is no inconvenience, and when the rotating secondary wheel passes over the guide waterfall, the rotating main wheel that has already been transferred onto the hanger rail supports the entire load, so there is no inconvenience such as the hanging wheel tilting in the front-back direction.

In addition, even in normal running conditions, the rotating main wheel and the rotating secondary wheels in front and behind it are in contact with the hanger rail at the same time, so
The front-to-back frame of the hanging wheel is eliminated, achieving the orderly arrangement that is the essence of a moving wall.

In addition, in the present invention, since one of the four sub-wheels is integrated with a guide collar, one of the four sub-wheels is provided on the main shaft near the hanging tool, like the rotating direction plate of the sub-wheel. Instead, the distance between the hanging wheel, which is the center of rotation of the hanging wheel, and the guide wheel, which is subject to rotational force, can be widened. Since the guide tsuba is integrated with the doron, the guide tsuba comes into contact with the hanger rail, etc. while rolling, so the guide tsuba does not dig into the hanger rail or the guide rail, and the hanging wheel can maintain smooth bending motion without the guide tsuba digging into or prying the hanger rail. .

This kind of smooth running is an extremely valuable effect for movable walls that use long hanging bolts to suspend and carry heavy walls, and to partition rooms beautifully, from the standpoint of preventing bending of the hanging bolts and uneven movement of the movable wall. .

In the present invention, since only one guide wheel is attached to the suspended vehicle body, it is similar to the conventional traveling trolley in which flanged wheels are provided before and after the rotating main body as shown in FIG.
There is no inconvenience such as the rotating collar biting into the edge of the bending hanger rail and making it impossible to move, and the outer surface of the central rotating wheel protrudes outward from the outer surface of the rotating secondary wheels in front and behind it. Because it is installed in such a way, the turning radius of the hanging wheel can be reduced by 4 degrees, and the radius of curvature of the hanger rail can be reduced.
Extremely economical.

Furthermore, in straight running sections and curved running sections other than branching sections of the hanger rail, the running direction of the hanging wheel is controlled by the guide wheel provided at the bottom of the hanging wheel, so the hanging wheel can operate smoothly, and the guide theory and guide groove are By bracing the wall, the hanging wheel is prevented from tilting in the left-right direction, and an orderly arrangement of the movable walls is achieved.
