Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a suspension device for a movable wall for transporting and arranging a movable wall to an arbitrary position, and in particular, the present invention relates to a suspension device for a movable wall for transporting and arranging a movable wall to an arbitrary position, and in particular, the present invention relates to a suspension device for a movable wall that can be smoothly moved and moved at orthogonal portions of hanger rails laid in a matrix on the ceiling. This invention relates to a highly practical movable wall suspension device that can freely change its direction.

In order to transport the movable wall to any desired position and freely partition the room, hanger rails, which are the locus of the hanging wheels, must be laid vertically and horizontally on the ceiling. If the hanger rails are laid vertically and horizontally, the hanger rails will inevitably intersect, causing various problems in that area. One is that such intersections require a cut in the hanger rail through which the shaft for hanging the movable wall from the hanging wheel passes, but when passing through the intersection, the wheels of the hanging wheel pass through this cut. It falls off and gives a big impact to the moving wall,
This will damage the hanging wheel and even the hanger rail. In addition, the running direction of the movable wall suspension must be changed at this intersection, but conventional equipment requires a rotary device that rotates the entire intersection, a complicated branching rail, and a control device for the running direction. In addition, various types of suspension wheels are required, such as one for turning and one for straight travel, making it difficult to control travel as needed.

The present invention has developed a special multi-stage hanger rail in order to solve the above-mentioned conventional problems at once, and by running on such a multi-stage hanger rail, it can be arranged in a matrix shape, that is, in a perpendicular shape. To provide a suspension device for a movable wall that can run in any direction without impact even on a part orthogonal to a hanger rail installed on a hanger rail.

Next, embodiments embodying the present invention will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is a front view of a suspension system according to an embodiment of the present invention (showing a state in which the upper vertical wheels are running on a hanger rail), and FIGS. 2 and 3 are
They are a top view and a left side view of the same suspended vehicle. In these figures, the suspension wheel body 1 has a narrow central body 2.
The upper body 3 and the lower body 4 are integrally connected. A hanging shaft 5, which is a kind of hanging tool that connects the suspension wheel main body 1 and a movable wall (not shown) below, is fixed or rotatably attached to the suspension wheel main body 1. Two vertical wheels 7, 7, 7', 7', which can run on the same plane, are rotatably attached to the left and right parallel side walls 6, 6' of the upper body 3. The vertical wheels 7, 7 are provided at a predetermined distance e1 in the front and rear, respectively, when viewed from the center line 8 of the hanging shaft 5 in the rolling direction thereof. The same applies to the vertical wheels 7', 7'.
Further, the front and rear side walls 9, 9' of the lower main body 4 are at right angles to the left and right side walls 6, 6', and the front and rear side walls 9, 9' are
It has two rotatable vertical wheels 10, 10 and 10', 10', each of which can run on the same plane. The vertical wheels 10, 10, 10', 10' are similar to the vertical wheels 9, 9, 9', 9' in that they are separated from each other by a predetermined distance e2 in the front and back relative to the center line 8. Due to the directionality of the vertical wheels as described above, the running direction of the vertical wheels 7, 7, 7', 7' and the running direction of the vertical wheels 10, 10, 10', 10' are perpendicular to each other.

One or more horizontal guide wheels 12 are attached to the upper surface 11 of the suspended wheel main body 1 as necessary.
This guide wheel 12 interferes with a vertical guide rail 14 provided as necessary at the upper center of the hanger rail 13 to regulate the running direction of the hanging wheel,
This makes it possible to stabilize the running condition. However, the guide wheels 12 and guide rails 14 may be unnecessary if the hanger rail does not have curved sections or straight or curved branch sections, and is only straight rails laid in a lattice pattern.

Next, the hanger rail on which the hanging wheel runs will be explained. This hanger rail 13 is the upper plate 1
left and right side walls 16, 16' connected by 5;
It has left and right upper rails 17, 17 and left and right lower rails 18, 18 protruding inward from the left and right side walls 16, 16', and upper flanges 20, 20 for holding an H-shaped steel 19 disposed in the attic. Consisting of H type steel 1
It is attached to the H-shaped steel 19 with set bolts screwed into the screw holes 21, 21 of 9.

The upper rails 17, 17 constitute a running surface for the upper vertical wheels 7, 7, 7', 7' of the hanging wheel, and as the hanging wheel runs, the cut 2 of the left and right upper rails 17, 17
2 through which the central body 2 of the suspension wheel passes. Lower rail 1
8, 18 are the lower vertical wheels 10, 10, 1 of the hanging wheel.
The cut 23 in the left and right lower rails 18, 18 is the part through which the hanging shaft 5 passes, in the part where the rails 0' and 10' run. Distance l between the upper surface 24 of the upper rails 17, 17 and the upper surface of the lower rails 18, 18
is the lower surface 25 of the upper vertical wheels 7, 7, 7', 7'
and lower vertical wheels. Equal to the distance from the bottom surface of 10, 10, 10', 10'. And upper rail 17,
17 and each side end of the lower rails 18, 18,
Arc-shaped notches 26, 26 and 27, 27 each having a depth d of about 1 mm are formed to avoid interference with vertical wheels rolling perpendicularly to the longitudinal direction. Therefore, when the upper vertical wheels 7, 7, 7', 7' are rolling on the upper rails 17, 17 and the hanging wheel is traveling in a direction perpendicular to the plane of the paper as shown in the first figure, the longitudinal direction of the rails is The lower vertical wheels 10, 10, 10', 10' that roll in the right angle direction are located above the arcuate notches 27, 27, and there is a gap between them corresponding to the depth d of the notches. , the lower vertical wheels 10, 10, 10', 10' and the lower rails 18, 18 do not contact or interfere,
This enables smooth running.

Next, the traveling operation and the switching operation of the traveling direction of this suspended vehicle will be explained. The traveling in the direction of the arrow X shown in FIG. 2 is as described above, with the upper vertical wheels rolling on the upper rail and the lower vertical wheels floating on the rail surface. on the other hand,
When the hanging wheel runs in the direction of the arrow Y perpendicular to this, it runs on the lower rails 18, 18 of the hanger rail 13' in the direction of the arrow Y, which is laid orthogonally to the hanger rail 13 in the direction of the arrow X. The vehicle travels by rolling the lower vertical wheels 10, 10, 10', 10'. In this case, the upper vertical wheels 7,
7, 7', and 7' are suspended from the upper rail 17 with a gap d of about 1 m/m by the notch 26, so that they do not pose a hindrance to running. FIG. 3 shows such a situation.

Figure 4 shows that the hanging wheels are hanger rails 13 and 13'.
This is a schematic representation from above using only the hanger rail and vertical wheels, showing the state where the machine is approaching the orthogonal part of the machine. Here, the solid line indicates the upper rail and the upper vertical wheel, and the two-dot chain line indicates the lower rail and the lower vertical wheel. Therefore, the portion indicated by arrow A indicated by the broken line indicates the lower rail and the lower vertical wheel. For example, consider a case where a hanging wheel is traveling in the direction of arrow X from the bottom of the paper and enters orthogonal section B of the hanger rail. As mentioned above, when the hanging wheel is in front of the orthogonal part, the upper vertical wheels 7, 7, 7',
7' rolls on the upper rails 17, 17, and the lower vertical wheels 10, 10, 10', 10' float from the lower rail 18. Orthogonal part B where the hanging wheel is shown in the figure
When it reaches the center of the upper vertical wheels 7, 7, 7',
7' are the notches 26 on the upper rails 17 and 17 side all at once.
It gets stuck inside and the hanging wheel itself descends about 1m/m. Since the notch 26 is a fine arc-shaped depression with a depth of about 1 m/m, the impact caused by this downward movement is negligible. When the entire hanging wheel descends by about 1 m/m in this way, the lower vertical wheels 10, 10, 10', 10', which had been floating, also come into contact with the arcuate notches 27 of the lower rails 18, 18. In this way, the hanging wheel falls into the four notches at the center of the orthogonal part B, so it stops completely.
If you do not apply a slightly larger force, it will stop stably so that it does not move in any direction, and at the same time all vertical wheels will come into contact with the hanger rail, so by pushing the moving wall with a slightly larger force, it will move in either the X or Y direction. It is also possible to move forward or backward in the direction of.

As described above, the guide wheels 12 can be arranged side by side in the X direction or in the Y direction. It is also possible to provide the guide rollers at three or four corners of the upper surface of the hanging wheel main body, and the arrangement of such guide rollers is appropriately determined depending on the basic design policy, such as the presence or absence of branch rails for straight and curved movement.

In addition, in the hanging wheel according to the present invention, since the vertical wheels are installed at positions spaced apart from each other by a predetermined distance e1 in front and back from the center of the shaft of the hanging tool, all the vertical wheels are attached to the breaks in the rail even at the orthogonal part of the hanger rail. There is no problem of them falling off at the same time, and even if the front (or rear) vertical wheel falls off into a break in the rail, the rear (or front) vertical wheel remains on the rail and supports the load of the moving wall. This ensures smooth running. That is, the fifth
As shown in the figure, the hanging wheel, which has been rolled to the right by the upper vertical wheels 7a, 7b, 7c, and 7d rolling on the upper rails 13, 13, is connected to the horizontal hanger rails 13, 13. When you reach the part perpendicular to the hanger rails 13' and 13' in the vertical direction,
As shown in the figure, the front wheels 7a and 7b of the upper vertical wheels pass over the cuts 22 and 23, which are the paths of the hanging shaft 5. At this time, the load of the moving wall is applied to the suspension shaft 5, so the front wheels 7a and 7b try to fall into the cut 22, but the rear wheels 7c and 7d
7 and supports the load, so the front wheels 7a and 7b
is prevented from falling off, and if you drive further to the right, the fifth
The state shown in Figure b is reached. At the position shown in the figure, the hanging wheel reaches the center of the rail orthogonal section B as described above,
Both the front and rear wheels are on the upper rail, and all the vertical wheels of the upper and lower tiers move onto the notches on the upper surface of the end of each rail, so the hanging wheel stably stops at that position. do. The fact that the hanging wheel automatically stops at the center of the orthogonal section means that the hanging wheel can always run in the center of any hanger rail, regardless of whether the hanging wheel subsequently moves forward, backward, left or right. This is an extremely important function for mobile wall hanging wheels. If you push the moving wall further to the right, the vertical wheels will escape from the notch, and the rear wheels will eventually reach the top of the cut in the rail, but at that point the front wheels are on the upper rails 17, 17 and support the load, so the rear The wheels are prevented from falling into the cut 22, and smooth running continues.

In the above embodiment, the cutout 26 or 27 was formed over the entire length of the hanger rail. However, in the straight part of the hanger rail, the upper rail 17 and the lower rail 18 are left with the running parts of the wheels, and the parts formed with the notches 26 and 27 at the side ends are cut vertically to form the sides of the hanger rail. It is also possible to avoid interference between the end and the wheels rolling perpendicularly to its longitudinal direction.

On the other hand, at the intersection of the hanger rail, as mentioned above, the above-mentioned notches 26 and 27 are necessary in order to stably stop the hanging wheel at the center of the intersection, so it is also possible to cut off the rail side end. It is also not possible to omit the notches 26, 27 at the ipsilateral end.

As described above, in the present invention, the movable wall is suspended below the hanging wheel main body 1 by the hanging shaft 2 attached to the hanging wheel main body 1, and is transported and moved along the hanger rail laid on the ceiling. In a movable wall suspension device for transporting and arranging a wall at an arbitrary position, the hanging wheel body 1 is configured to include an upper body 3 and a lower body 4, and the hanger rail is attached to the upper part of the hanging wheel body 1. The structure includes upper rails 17, 17 and lower rails 18, 18 corresponding to the main body 3 and the lower main body 4, and the upper rail of the hanger rail is attached to each of the parallel side walls 6, 6' of the upper main body 3. Two upper vertical wheels 7, 7, 7', 7' rolling on each of the upper vertical wheels 7, 17 are attached to the upper body side wall 6, of the lower body 4 provided below the upper body 3.
Two lower vertical wheels 10, 10, 10', 10' rolling on the lower rails 18, 18 of the hanger rail are attached to each of the side walls 9, 9' perpendicular to the upper vertical wheels 7, 6'. , 7', 7' at right angles to the upper vertical wheels 7, 7, 7', 7' and the lower vertical wheels 10, 10, 10', 10', respectively, when viewed in their rolling direction. The upper rails 17, 17 and the lower rails 18, 1 are installed at a predetermined distance apart from the axis center lines 8, 8' of the shaft 5.
At each side end of 8, in order to avoid interference with vertical wheels rolling perpendicular to the longitudinal direction of each rail,
This suspension system for moving walls is characterized by the fact that each vertical wheel has a notch formed therein to stably stop it, so the vertical wheel falls off at the rail cut at the orthogonal part of the hanger rail. Moreover, even when the front wheel is passing over the above-mentioned cut, the rear wheel remains on the rail, and the hanging wheel is supported by the left and right or two front and rear vertical wheels, so the hanging wheel does not swing back and forth or left or right. This makes the running condition extremely stable, and by combining it with the upper and lower two stages of hanger rails, the running direction can be adjusted 90 degrees at once at the orthogonal part of the hanger rails.
It is an extremely practical suspension wheel that can change the angle of rotation, does not require an expensive rotary device, and can easily change direction either left or right or front and back.
