Description

[Detailed Description of the Invention] The present applicants have already provided one or more rotating sub-wheels in front of or behind the hanging car body, or in front and behind the main body of the hanging car as a bending travel control device for a movable wall hanging car. The present invention proposes a movable wall hanging car with guide wheels (Patent Application No. 171799/1983) that controls the running direction by attaching a collar and interfering with the hanger rail. Further improvements have been made to improve the bending and stable running performance of the mobile wall hanging wheel, and
This invention relates to a hanging wheel that prevents wear of the hanger rail and further reduces costs by making the hanger rail more compact.

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, it is necessary to make the hanging wheel itself bendable (especially when the hanging wheel itself is bendable). (See Japanese Utility Model Publication No. 51-51568). However, in this case, the mechanism to make the hanging wheel itself bendable is complicated and requires many bearings, making it expensive, and the bending part bends, causing problems such as impact when passing through the cut in the hanger rail. There are drawbacks that arise. In the other case, since there is a rotation direction plate that acts as a guide inside the drive wheel that carries the load, the distance between the center of rotation and the rotation direction plate is short and the rotational moment is small, so the hanging wheel does not change direction as expected. Furthermore, since the rotation direction plate is rotatable independently of the drive wheel, 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.
There was a drawback that the rotation direction plate was squeezed by the hanger rail, preventing smooth rotation and movement of the hanging wheel.
The poor bending performance of such hanging wheels is due to
The more wheels there are to support the hanging wheel, the larger the number of wheels will be.
In the case of hanging wheels arranged in rows or more, bending motion was most difficult.

In view of these points, we proposed the above-mentioned movable wall hanging wheel with guide wheels, which has a pair of rotating main wheels 2 on the left and right sides of the hanging wheel main body 1, as shown in FIGS. 1 and 2.
2 is rotatably provided, and one or more rotating sub wheels are rotatably attached in front of or behind the rotating main wheel 2, or before and after the rotating main wheel 2. In the example shown in the figure, there are two rotating sub-wheels 3a, 3b, 3c, 3d at the front and rear.
One of the subwheels 3a is provided with a disc-shaped guide collar 4 that is integral with the subwheel 3a. The auxiliary wheel integrally provided with the guide collar 4 in this manner is particularly called a guide wheel. Further, one or more horizontally provided guide wheels 5 are attached to the lower part of the suspension wheel main body 1, and guide wheels 5 are installed on the axes of the main wheels 2, 2 so as to be rotatable with respect to the suspension wheel main body 1. A suspension bolt 6 is fitted vertically, and a movable wall is suspended from the lower end of the suspension bolt 6.
The subwheels 3a to 3d roll on the bottom walls 8, 8 of the hanger rail 7 installed on the ceiling to transport the movable wall suspended from the hanging bolts 6. Since the guide wheel 5 is inserted into the guide groove 9 between the two, as long as the guide groove 9 continues continuously, the hanging wheel will be guided by the guide groove 9 and run straight or curved. However, as shown in FIG. 1, at a portion where the guide groove 9 branches into a guide groove 9a in the straight direction and a guide groove 9b in the bending direction, the guide ring 5 is moved in the direction of the guide groove 9a ( Since the hanging wheel can move either in the direction of the guide groove 9b (in the direction of the arrow ( )), the hanging wheel gets stuck at the branch point, and the control function for the running direction is lost. Therefore, in the conventional hanging wheel, a substantially triangular guide rail 11 whose oblique side 10 forms an arc as shown in the figure is attached to the lower surface of the upper wall 12 of the hanger rail 7, and the collar 4 of the leading guide wheel 3a and the oblique side of the guide rail 11 are attached to the lower surface of the upper wall 12 of the hanger rail 7. 10 and the guiding wheel 3a changes direction along the oblique side, so that the entire suspended wheel is dragged by the guiding wheel and travels in a bending direction in the direction of the arrow ( ). By using a suspension wheel with a guide wheel provided at the position of the secondary wheel 3b, the guide collar passes between the orthogonal side 13 of the guide rail 11 and the bottom side surface 14 of the hanger rail, so that the guide collar and the guide rail are connected. It is configured so that the hanging wheel runs straight without interference.

As described above, such a movable wall suspension wheel with a guide wheel obtains a large rotational moment by applying a rotational force to the collar 4 of the guide wheel 3a located at a distance from the rotating main wheel, which is the center of rotation of the suspension wheel. Because it is a heavy object, even when hanging a large moving wall with heavy objects,
It is convenient because it can be bent and traveled extremely easily, but since the diameter of the tsuba 4 is larger than the diameter of the guide wheel 3a, the outer periphery of the tsuba 4 is smaller than the distance that the outer periphery of the guide wheel 3a moves (traveling distance). Since the amount of movement is larger, the length of contact between the collar 4 and the oblique side 10 of the guide rail 11 becomes longer while the hanging wheel travels for a unit length, and the interference part between the collar 4 and the guide rail 11 becomes longer. A drawback was discovered that caused increased wear. Furthermore, providing a flange on the guide wheel is disadvantageous as it increases processing costs.

Therefore, the first object of the present invention is to provide a hanging wheel for a moving wall that can support a moving wall with a large and heavy load and that has less wear due to contact between the wheels and the guide rail. , a pair of small-diameter rotating main wheels are provided on the left and right sides of the integral hanging wheel main body, and a movable wall hanging tool is arranged on the axis of the rotating main wheels,
A pair of rotating sub-wheels are attached to the sides of the suspension wheel main body before and after the above-mentioned rotating main wheel, and the rotating sub-wheel provided on one side of the suspension car body has a larger outer diameter than the rotating sub-wheel provided on the other side. Furthermore, the rotating main wheel is installed at a position where the outer surface of the rotating main wheel protrudes outward from the outer surface of the rotating sub-wheel adjacent to the rotating main wheel, and the rotating main wheel is installed in a position where the outer surface of the rotating main wheel protrudes outward from the outer surface of the rotating sub-wheel adjacent to the rotating main wheel. This invention relates to a movable hanging wheel for a movable wall, in which one guide ring is attached to each eccentric position to be fitted into a guide groove of the hanger rail and guide the hanging wheel body along the hanger rail.

In addition, such a system in which the outside diameter of the wheels is made different and the running direction of the hanging wheel is controlled by interfering with the guide rail provided on the hanger rail by the large-diameter wheels is already known, for example, in Japanese Patent Publication No. 55-9513. ing. However, in the case of this known example,
The suspension wheel main body of the present invention is composed of a runner half body and a runner half body divided into two parts, which are connected to each other so as to be freely rotatable (bendable). Furthermore, only a pair of wheels are provided on each of the rear half and front half of the runner. Therefore, when crossing a cut in the hanger rail, either the front or rear wheels will fall into the cut, making it impossible to run, especially if the load is heavy. In addition, such a bending type hanging wheel cannot apply much force to the bending part, so it is not suitable for a large moving wall that carries a large load, and the mechanism is complicated, making it expensive. In order to solve these problems, the present invention makes the main body of the hanging wheel non-bendable, and even if the pair of wheels is placed in the cut of the hanger rail, the wheel supporting the load is always on the hanger rail. In order to prevent the wheels from falling off, the suspension wheel is supported by three pairs of front, middle, and rear wheels (six in total) on the sides of the suspension wheel. However, in the case of such a six-wheeled suspension vehicle, there are many wheels that touch the ground on the hanger rail, so when a moving wall with a large load is suspended, the friction between the rail surface and the wheels is large and the direction of the suspension vehicle is changed. It is not easy to cause the wheels to slip. The hanging wheel of the above-mentioned known example (Japanese Patent Publication No. 55-9513) takes this point into consideration and makes the hanging wheel body bendable, making it extremely easy to change the running direction. is not suitable for Therefore, in the case of the above-mentioned six-wheeled suspended vehicle, in order to change the traveling direction, it is necessary to apply a larger turning torque to the suspended vehicle body compared to other suspended vehicles. Not enough. Therefore, in this invention, the wheels (front and rear secondary wheels) located far from the hanging device, which is the center of rotation of the hanging wheel, are made larger in diameter than the other secondary wheels to increase rotational torque and enable smooth turning of the hanging wheel itself. This is what I did.

Therefore, the second object of the present invention is to construct the suspension wheel main body in one piece, and to construct the suspension wheel main body in the front stage,
Three elements were organically incorporated: providing a pair of wheels in the middle and rear stages (six in total), and making the front and rear wheels that are farthest apart from the center of the suspension wheel larger in diameter than the others so that they interfere with the guide rail. The purpose of this invention is to enable smooth rotation of a hanging wheel for heavy loads.

Further, the third objective of the present invention, which is to reduce the size of the hanger rail, is achieved by attaching the main rotating wheel to a position such that its outer surface protrudes outward from the outer surface of the secondary rotating wheel.

That is, as shown in FIG. 6, in a suspended vehicle in which three wheels b are attached to each end of a suspended vehicle body a in a straight line,
Even if one of the wheels cannot bear the load when it crosses the groove d of the branch part c of the hanger rail and floats in the air, the load is borne by the remaining wheels,
This prevents vibrations from being transmitted to the moving wall, but in this case, when a hanging wheel a runs on a hanger rail as shown in the figure, where a curved rail f branches from a straight rail e at a branching point c, the tip wheel b ’ tip point g
moves along a trajectory k as shown by the two-dot chain line, so its tip point g and the side wall h of the hanger rail
In order to avoid this, the side wall h of the hanger rail must be placed outside the locus k, which increases the overall width of the hanger rail connected to it, and increases the width by at least the length m. However, I have no choice but to use a large hanger rail. However, since the movable wall travels on hanger rails installed vertically and horizontally on the ceiling, increasing the size of the hanger rails significantly increases the cost of constructing the movable wall. This inconvenience is unique to a suspended vehicle in which more than one pair of front, middle, and rear wheels (six in total) are attached to the suspended vehicle body.

Therefore, in such a suspended wheel, the width of the wheel itself is n,
Therefore, the width of the hanging wheel body is made as small as possible, but since the hanging tool i for hanging the movable wall is rotatably attached to the hanging wheel main body, when the width of the hanging wheel main body is narrowed, this hanging tool The area of the attachment part of i also becomes narrower, which impedes the rotational performance of the hanging tool.

On the other hand, when the hanging wheel a shown in FIG. If we pay attention to the movement trajectory, it forms a roughly circular arc shape, as shown by a dashed line k'', and passes inside the trajectory k along which the tip point g of the leading wheel b' passes.

Therefore, in order to avoid interference between the leading wheel b' and the side wall h of the hanger rail, the trajectory of the tip point g of the leading wheel b' must be different from the trajectory k'' of the tip point of the central main wheel b''. It is only necessary to make the wheels come inward, and for that purpose, as in the present invention, the temporal wheels should be placed on the inside.
b' may be placed inward to the position indicated by the two-dot chain line.

This is nothing more than making the distance from the center point of the hanging wheel to the outer surface of the rotating main wheel longer than the distance from the center point of the suspended wheel to the outer surface of the rotating sub-wheel in the present invention.

By adopting such a configuration, it is possible to avoid interference between the rotating secondary wheel and the outer wall h of the hanger rail, and the width can be made narrower than that of a conventional hanger rail for a hanging vehicle. As shown in the central wheel (rotating main wheel in the present invention)
If there is enough space between the curved trajectory k'' of b'' and the side wall h of the hanger rail, the center wheel
b'' can be made to protrude further outward, and the width n' of the central body of the suspended wheel can be increased accordingly.
(does not interfere with the side wall of the hanger rail), the mounting area of the hanging fixture i on the movable wall can be secured even wider, which improves the rotational performance of the hanging fixture i and enables smooth transportation of the movable wall. It is.

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

In FIGS. 3 and 4, the suspension wheel main body 21, which forms the main body of the suspension wheel 20, is integral as shown and has a vertical insertion hole 22 in the center, and a movable wall hanger fitted into the insertion hole 22. The head 24 of the hanging bolt 23, which is an example, is installed in a step 25 provided at the upper part of the insertion hole 22, and is prevented from coming out by a lid 26 screwed onto the upper part of the step 25. Prevented. The side walls of the hanging wheel body 21 have projecting parts 27, 27 that project in the left and right directions, respectively. Freely rotating main wheels 29, 29 are fitted, and the center line 30 of the main wheels 29, 29 is perpendicular to the center line 31 of the hanging bolt 23. Therefore, the hanging bolt 23
The applied axial force (weight of the moving wall, etc.) acts equally on the main wheels 29, 29. Rotatable secondary wheels 34, 3 are provided on the rear side surfaces 32, 33 of the hanging wheel main body 21.
5 is attached, and rotatable secondary wheels 38, 39 are also attached to the front side surfaces 36, 37.
Among the four sub-wheels mentioned above, the outer diameters of the sub-wheels 35 and 39 attached to the right side surfaces 33 and 37 facing the front are as follows:
The outer diameter of the main wheels 29 is larger than that of the main wheels 29, and the subwheel having such a large outer diameter is particularly called a leading wheel. Further, the outer diameters of the other sub wheels 34 and 38 are the same as those of the main wheels 29 and 29.

Shafts 40 and 41 protruding from the lower part of the suspension wheel body 21
A guide groove 43 of the hanger rail 42 is provided to guide the hanging wheel and to prevent the hanging wheel from lateral vibration.
Horizontal guide wheels 44 and 45 fitted in are rotatably provided.

Note that since the leading wheels 35 and 39 have a large outer diameter, they may interfere with the guide rail 47 provided on the upper surface 46 of the bent portion of the hanger rail by the length L; Since the wheels 34 and 38 have small diameters, they do not interfere with the guide rail 47.

Next, the operation of the present invention will be explained using the suspension wheel shown in FIG. 3 as an example with reference to FIG. 5. Fifth
The figure shows the behavior of the hanging wheel at the branching part of the hanger rail.
is seen from the direction of arrow A. In the figure, 48 is the right wall of the hanger rail, 49 is the left wall, and the upper wall 46' in FIG. 4 is omitted in FIG. 5. Further, 47 is a guide rail fixed to the upper wall 46'. FIG. 5 shows a bifurcation between a straight portion 50 and an arcuate bent portion 51 of such a hanger rail, and 43 is the guide groove.

Therefore, first, as shown in Fig. 5a, the leading wheel 3
9 and 35 are traveling on the straight rail 50 side, the hanging wheel 20 traveling straight in the direction of arrow B is connected to the guide groove 43 at the branching part of the guide wheels 44 and 45.
Since the guide wheel 44 is released from the restraint, the direction control function by the guide wheel 44 is lost, but instead, the leading wheel 39 runs along the linear side surface 52 of the guide rail 47, so it is guided by this and is guided by the chain double-dashed line. Shown 2
Drive straight to position 0a.

Next, when the leading wheel 39 travels on the bent rail 51 side as shown in FIG. is twisted in the direction C along the oblique side 53 of the guide rail 47, so if it continues as it is, the oblique side 5
3, the leading wheel 39 is guided to the position shown by the two-dot chain line 20b.

When passing through the branching rail section in this way, the hanging wheel must cross the cut 54 in the hanger rail made by the branching guide groove;
As in the above embodiment, the suspension bolt 23 is connected to the main wheels 29, 2.
If the main wheel 29 is perpendicular to the axis of the main wheel 29 and one subwheel is provided at the front and rear of the main wheel, when the leading or following subwheel is crossing the cut, the main wheel 29 will be on the hanger rail and the load will be reduced. is supported by the main wheels. Also, when the main wheel 29 passes through the cut 54,
The front and rear secondary wheels are on the hanger rail and support the load. Therefore, the load on the hanging bolt is always stably supported by one of the wheels, so even when passing through a cut, there is no chance of a wheel falling into the cut and applying an impact to the moving wall.

As described above, the present invention provides a pair of small-diameter rotating main wheels on the left and right sides of an integrated hanging wheel main body, a movable wall hanging tool is arranged on the axis of the rotating main wheels, and the rotating main wheels A pair of rotating sub-wheels are attached to the front and rear sides of the suspended wheel main body, and the rotating secondary wheel provided on one side of the suspended wheel main body is used as a rotating leading wheel having a larger outer diameter than the rotating secondary wheel provided on the other side, and A rotating main wheel is attached to a position where the outer surface of the rotating main wheel protrudes outward from the outer surface of a rotating sub-wheel adjacent to the rotating main wheel,
In addition, one guide ring is attached to the bottom of the hanging wheel at a position eccentric to the front and back from the movable wall hanging tool, which guides the hanging wheel main body along the hanger rail by fitting into the guide groove of the hanger rail. The distance at which the outer periphery of the leading wheel and the guide rail interfere with each other becomes the same as the moving wall of the hanging wheel, reducing the relative amount of friction and the amount of wear between the two. Since the rotating guide wheel is as far away from the center of the hanger body in the front and back as possible, the turning torque due to interference with the guide rail is large, and even though it is a 6-wheel type and has a large frictional force with the hanger rail, it can support a large load. However, since the running direction can be smoothly changed, and the radius of the rotation locus is small, the hanger rail can be downsized, which eliminates the drawback of the six-wheeled hanging vehicle that the hanger rail becomes large. Further, since the leading wheel does not require a flange and can be a simple disc-shaped one, the bearing itself can be used as is if necessary, resulting in low cost. Furthermore, since it is constructed with six wheels as shown in FIG. 3, the wheels do not fall into the cut when passing through the cut in the hanger rail, and the running condition is extremely stable.
