Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a suspension support device for suspending and supporting a movable partition wall so that it can travel.

[Prior Art] Recently, banquet halls of hotels, offices, etc. are often equipped with movable partition walls that can easily partition large floors as needed.

This type of movable wall is suspended and supported from a ceiling rail via suspension rods at two locations, front and back, and can be moved along the ceiling rail. Such a movable wall needs to be moved in various ways for storage etc.
It is constructed so that it can pass through the place where the ceiling rail is joined at right angles.

However, as a suspension support device in this case,
For example, one ceiling rail has first rail parts on both sides of a continuous downward opening, and one ceiling rail has a continuous downward opening perpendicular to the downward opening. The movable wall is suspended through the other ceiling rail comprising a pair of second rail parts on both sides, and a suspension rod that is movably disposed within the ceiling rail and inserted through the downward opening. a supporting running body; and a pair of first running rollers that are pivoted on two opposing sides of one of the running bodies and roll on the first rail portion when the running body runs within one of the ceiling rails. and the second shaft is pivoted to the other two sides of the traveling body, and when the traveling body runs within the other ceiling rail, the second
A device is known that includes a pair of second running rollers that roll on a rail portion.

[Problems to be solved by the invention] By the way, with such a structure, guide rollers and sliders are provided at the four corners of the traveling body, and these are brought into rolling or sliding contact with the inner surface of the side wall of the ceiling rail. This allows the traveling body to travel within the ceiling rail without turning horizontally.

However, with such a configuration, when the traveling body reaches the intersection of the ceiling rails, the guide roller or slider cannot roll or slide into contact with the side wall of the ceiling rail. Therefore, the traveling body turns horizontally at this intersection,
This may cause a problem that it becomes impossible to advance into the desired ceiling rail.

As a measure to deal with such a problem, support balls for rollingly supporting the lower surface of the traveling body are disposed at the four corners of the intersection of the ceiling rails, and the upper end of the support ball is provided on the lower surface of the traveling body. Guide grooves having a partially arcuate cross section that are engaged with are provided in a lattice pattern, and the engagement between these guide grooves and each of the support balls prevents the traveling body from turning horizontally at the intersection of the ceiling rails. Something has been developed to prevent this.

However, with this configuration, when the traveling body is located at an intersection, the four support balls described above must be assembled accurately at each intersection of the lattice-shaped guide grooves. The load acting on the running body forces the support ball against the deviated portion of the partially arcuate guide groove, and as a reaction, a pivoting force or other harmful force acts on the roller block. Therefore, the smooth operation of the traveling body is hindered. In particular, two parallel second ceiling rails are branched from one first ceiling rail, and the movable wall that has been moved in the width direction along the first ceiling rail is then moved to both second ceiling rails. Problems tend to occur when moving along the rail in the thickness direction. In other words, in such a case, the first
At each intersection between the ceiling rail and the second ceiling rail, if the intersections of the four support balls and the guide grooves of the traveling body do not match accurately, both roller blocks that suspend and support both ends of the movable wall will be suspended. cannot be smoothly guided into both second ceiling rails at the same time. However, when moving the movable wall in this manner, if there is even a slight hitch in the movement of the moving body, there is a serious problem in that the movable wall will begin to tilt and its normal movement will be hindered. arise. To be more specific, recently, this type of movable wall has been developed that is much taller than a human being, and in order to move such a movable wall, the lower half of the wall must be pressed. I have no choice but to do it. When moving the movable wall in the width direction along the first ceiling rail, the pair of traveling bodies are positioned at intervals in the traveling direction, so the weight of the movable wall is not extremely small. As long as there is some resistance to the traveling body, the movable wall will not tilt, and the pressing force will effectively act as a force for moving the traveling body forward.
However, when moving the movable wall in the thickness direction along both the second ceiling rails, it is necessary to move both the traveling bodies side by side at the same time. Therefore, if the lower half of the movable wall has to be pressed, and the traveling bodies cannot run smoothly, the pressing force acts as a force that tilts the movable wall in the thickness direction. In other words, if there is a catch in the running of the traveling body, even if you press the moving wall, the moving wall will only tilt in the thickness direction using the traveling body part as a fulcrum, and will not move along the second ceiling rail. This causes a serious problem in that it becomes impossible to do so.

Therefore, in order to avoid such problems with conventional devices, there is a problem in that very high assembly accuracy is required.

The present invention aims to solve these problems.

[Means for Solving the Problems] In order to achieve the above objectives, the present invention employs the following configuration.

That is, the suspension support device for a movable wall for a partition according to the present invention includes a pair of rail parts on both sides of a continuous downward opening, and a ceiling rail connected at right angles to the ceiling. a running body that is movably disposed within the rail and suspends and supports the movable wall via a suspension rod inserted into the downward opening; and a running body that is pivoted to the running body and rolls on the rail portion. A running roller is horizontally rotatably pivoted at a corner diagonal position on the lower surface of the running body, and when the running body runs within the ceiling rail, it rolls into contact with the inner surface of the side wall of the ceiling rail to prevent the running body from running. a pair of guide rollers that regulate the posture; a non-directional rotary support member that is provided at the intersection of the ceiling rails and supports the flat lower surface of the traveling body from below; and the intersection of the ceiling rails. is provided to protrude from the rail surface and locks the outer circumferential surface of the guide roller to prevent the traveling body from horizontally turning until the axis of the guide roller is located outside the inner surface of the side wall of the guide rail into which it should enter. It is characterized by comprising a locking protrusion for preventing excessive turning.

[Function] With such a configuration, the lower flat part of the traveling body is supported by the non-directional rotational support member at the intersection of the ceiling rails, so that the traveling body does not cross at the intersection. There is no falling motion.

Moreover, even if the traveling body turns horizontally at the intersection of the ceiling rails, the axis of the guide roller provided on the lower surface of the traveling body will deviate outward from the inner surface of the side wall of the ceiling rail that it is about to enter. Before this, the outer circumferential surface of the guide roller comes into contact with a locking protrusion protruding from the rail surface of the ceiling rail and is locked. Therefore, the traveling body is no longer able to horizontally turn. However, if the axis of the guide roller is located inside the inner surface of the side wall of the ceiling rail that is about to enter, as the traveling body approaches,
Even if the guide roller comes into contact with the edge of the side wall, the guide roller will be pushed inward as the traveling body moves forward. Moreover,
Since this guide roller is horizontally rotatable, it can be retracted inward without sliding while keeping a specific part of its outer circumferential surface in contact with the edge of the side wall, and the traveling body can move smoothly. The direction will be corrected and it will proceed from the intersection into the ceiling rail.

However, since this allows horizontal turning of the traveling body at an intersection to some extent, a relatively large clearance should be provided between the locking protrusion and the guide roller of the traveling body at the intersection. is possible. Therefore, high precision is not required for the assembly positions of the guide roller and the locking protrusion.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, this suspension support device for a movable partition wall includes one ceiling rail 1 having a continuous downward opening 1a, and a ceiling rail 1 that is perpendicular to the downward opening 1a. movement via the other ceiling rail 2 having a downward opening 2a and a suspension rod 3 that is movably disposed within the ceiling rails 1, 2 and inserted through the downward openings 1a, 2a. A running body 5 that suspends and supports the wall 4, and a first,
It is equipped with second running rollers 6 and 7.

The ceiling rails 1 and 2 are buried in the ceiling of a building, and have bottom walls 11 and 21 having continuous downward openings 1a and 2a in the center exposed on the ceiling surface. In one ceiling rail 1, a pair of first rail parts 12 parallel to the bottom wall 11 are integrally provided and positioned on both sides of the downward opening 1a. Further, inside the second ceiling rail 2, a pair of second rail parts 22 parallel to the bottom wall 21 are integrally provided so as to be located on both sides of the downward opening 2a. The one ceiling rail 1 and the other ceiling rail 2 are joined to each other by crossing at right angles. That is, four connection support members 8 are arranged at the intersection, and these connection support members 8 connect the first rail part 12 and the second rail part 22 in a positioned state. has been done. The connection support member 8 is an L-shaped metal fitting, and one end side 8a
is fixed between the first rail portion 12 of one ceiling rail 1 and the bottom wall 11 using bolts 81 and plate nuts 82, and the other end side 8b is fixed using bolts 81 and plate nuts 82. It is fixed between the second rail part 22 of the other ceiling rail 2 and the bottom wall 21 using a. The upper surface of each connection support member 8 is a first
It forms a part of the flat rail part surfaces 12a, 22a formed on the upper surfaces of the second rail parts 12, 22, and one ceiling rail 1 is located between the central bent part 8c.
A cross-intersecting portion is formed between the downward opening 1a and the downward opening 2a of the other ceiling rail 2.

The traveling body 5 is a block having a substantially rectangular outer shape in a plan view, and the upper end of the suspension rod 3 is tiltably connected to the center of the block. A first running roller 6 is provided on one of the two opposing sides of the roller block 5.
is rotatably mounted on the shaft, and a second running roller 7 is rotatably mounted on the other two opposing sides. Note that two traveling bodies 5 are provided for each moving wall 4. When the traveling body 5 travels within one ceiling rail 1, the first traveling roller 6 rolls on the first rail portion 12 with the second traveling roller 7 floating. When traveling on the other ceiling rail 2, the second traveling roller 7 rolls on the second rail section 22 with the first traveling roller 6 floating. There is.

Two pairs of guide rollers 51 ₁ to 51 ₄ are pivoted to horizontally rotatable positions at diagonal corners of the lower surface 5a of the traveling body 5. That is, catch seats 52 are integrally formed at the four corners of the traveling body 5.
The guide roller 51 ₁ is attached to the lower surface of these seats 52.
~ ₅₁₄ is attached using the shaft 53. The guide rollers 51 ₁ to 51 ₄ have their outer circumferential surfaces 51 a projecting outward beyond the outermost surface 5 c of the traveling body 5 .
Inner surfaces 1 of the side walls 14 and 24 of the ceiling rails 1 and 2
4a and 24a. The lower surfaces 51 of these guide rollers 51 ₁ to 51 ₄
The height position b is located below the flat portion 54 formed on the lower surface 5a of the traveling body 5.

Moreover, the four corners of the intersection of the ceiling rails 1 and 2, more specifically, the four corners of the intersection of the ceiling rails 1 and 2, specifically, the rectangular shape in plan view surrounded by the parallel running track of the first running roller 6 and the parallel running track of the second running roller 7. Two pairs of non-directional rotation support members, for example support balls 83, are provided at diagonal positions at the corners of the area. Specifically, a support ball 83 is rotatably held on the upper surface of the central bent portion 8c of each of the connection support members 8. The upper end portion of the support ball 83 protrudes above the upper surface of the connection support member 8, and a flat portion 54 formed on the lower surface 5a of the traveling body 5 located at this intersection.
can be supported in rolling contact by these support balls 83. That is, the traveling body 5 passing through this intersection is held at approximately the same height position by these support balls 83 as when traveling within the ceiling rails 1 and 2.

Furthermore, locking protrusions 91 ₁ to 91 ₈ are provided on the rail portion surfaces 12a, 22a at the intersections of the ceiling rails 1, 2 to prevent the traveling body 5 from excessively horizontally turning. Each locking protrusion 91 ₁
- 91 ₈ are pin-shaped members, and are implanted on the upper surface of the connection support member 8 so as to be positioned outside the regular running track a of each of the guide rollers 51 ₁ - 51 ₄ .
Specifically, the installation positions of these locking protrusions 91 ₁ to 91 ₈ and the outer diameter dimensions of the guide rollers 51 ₁ to 51 ₄ are such that the traveling body 5 located at the intersection n
In other words, the axis b of the guide rollers 51 ₁ to 51 ₄ is located outside the inner surfaces 14 a and 24 a of the side walls 14 and 24 of the ceiling rails 1 and 2 on which the traveling body 5 is to travel. At a position well before the transition, the guide rollers 51 ₁ to 5
The locking protrusion 91 ₁ to which the outer circumferential surface 51a of 1 ₄ corresponds
The value is set so that it will come into contact with 91 ₈ . In this example. Specifically, the outer diameter of the guide rollers 51 ₁ to 51 ₄ is set to approximately 1/4 of the length of one side of the traveling body 5, and each of the locking protrusions 91 ₁ to 91 ₄ is set to approximately 1/4 of the length of one side of the traveling body 5. Guide roller 51 ₁ ~
51 ₄ as close as possible to the regular running trajectory a. The height dimension of each of the locking protrusions 91 ₁ to 91 ₈ is smaller than the protrusion height dimension of the support ball 83, _and
It is set to a value that allows it to come into contact with the outer circumferential surface 51a of No. ₁₄ .

With such a configuration, at the intersection of the ceiling rails 1 and 2, the lower surface 5a of the traveling body 5
Since the flat portion 54 formed at the top is supported by the support ball 83 in rolling contact, the first running roller 6 and the second running roller 7 do not remain under the ceiling rails 1 and 2 even when the running body 5 reaches the intersection n. It will not fall into the openings 1a and 2a. And this support ball 83
Since it is non-directional and can roll in all directions, the traveling body 5 at the intersection n can be guided into either of the ceiling rails 1 and 2 depending on the degree of force applied.

Moreover, even if the traveling body 5 turns horizontally at the intersection of the ceiling rails 1 and 2, the traveling body 5
The axis b of the guide rollers 51 ₁ to 51 ₄ provided on the lower surface 5a of the
The outer peripheral surfaces 5 of the guide rollers 51 1 to 51 4 are located before the inner surfaces 14 a and 24 a of the guide rollers 51 ₁ to 51 ₄ are deviated outward.
1a is a locking protrusion 9 protruding from the ceiling rails 1 and 2;
1 ₁ to 91 ₈ and are locked. Therefore, the traveling body 5 can no longer horizontally turn. Specifically, when the traveling body 5 horizontally turns, for example, in the clockwise direction in the figure, at the intersection n, the guide rollers 51 ₁ to 51 ₄ engage the locking protrusions 91 ₂ and 51 4 at the position shown in FIG. It is locked by 91 ₄ , 91 ₆ , 91 ₈ . When the traveling body 5 starts moving, for example, to advance into the ceiling rail 2, the guide roller 51 ₃ on the rear side in the traveling direction is guided by the corresponding locking protrusion 91 ₆ and is pressed inward. With,
The guide roller 51 ₄ on the front side in the traveling direction is guided by the corresponding locking protrusion 91 ₈ and guided outward. Therefore, as the traveling body 5 advances, its attitude is gradually corrected to the normal orientation. When the traveling body 5 enters the ceiling rail 2, as _shown in FIG. There is, but in that case,
so that the axis b of the guide roller 51 ₁ is reliably located inside the inner surface 24 a of the side wall 24;
The horizontal turning of the traveling body 5 is caused by the locking protrusion 91 ₆ ,
₉₁₈ . Therefore, even if the guide roller 51 ₁ comes into contact with the edge 24b of the side wall 24 of the ceiling rail 2, the guide roller 51 ₁ will not move as the traveling body 5 advances.
Pressed inward. That is, the guide roller 51 ₁
However, the edge 2 of the side wall 24 of the ceiling rail 2 to be entered
4b, if the axis b of the guide roller 51 ₁ is located inside the inner surface 24 a of the side wall 24 , the axis b of the guide roller 51 1 may be damaged as the traveling body 5 moves into the ceiling rail 2 . As the center b moves forward, an inward pressing force acts on the support shaft 51b of the guide roller ₅₁₁ . Therefore, the traveling body 5 has its attitude further corrected, and enters into the ceiling rail 2 in the normal attitude, as shown in FIG. 5c. A similar effect occurs when the traveling body 5 enters the ceiling rail 1 from the intersection n.

Therefore, in this device, the locking protrusion 91
Since the guide rollers _{51 1} to 51 ₄ that are horizontally rotatable are in contact with the side walls ₁₄ and 24, sliding of the members is prevented even when correcting the horizontal turning attitude of the traveling body 5. There is nothing to accompany it. Therefore, when the traveling body 5 advances from the intersection n to the required ceiling rails 1 and 2, its advancing operation may become impossible, or
It can be moved smoothly without getting caught. Moreover, since this device allows horizontal turning of the traveling body 5 at the intersection n to some extent, the guide rollers 51 ₁ to 51 ₄ at the normal position at the intersection n and the locking protrusion 91
A relatively large clearance can be provided between ₁ and ₉₁₈ . Therefore, the guide rollers 51 ₁ to 51 ₄ and the locking protrusions 91 ₁ to 9
1 High precision is not required for the assembly position of ₈ .

Furthermore, this one has guide rollers 51 ₁ for regulating the posture of the traveling body 5 within the ceiling rails 1 and 2.
₅₁₄ is effectively used to restrict the horizontal turning of the traveling body 5 at the intersection, so the number of parts is small and implementation is easy.

Furthermore, since the locking protrusions 91 ₁ to 91 ₈ are provided on the rail surface 12a, 22a of the ceiling rails 1, 2, there is no need to provide a protrusion or the like on the upper surface 5b of the traveling body 5 to prevent horizontal rotation. . Therefore, the ceiling walls 13, 23 of the ceiling rail can be brought close to the upper ends of the traveling rollers 6, 7 without any difficulty. Therefore, there is an advantage that ceiling rails 1 and 2 having small dimensions in the vertical direction can be used.

Note that the shape of the locking protrusion is not limited to a pin shape, but may be a prismatic shape. The locking protrusion may be formed integrally with the rail portion surface.

Further, in the above embodiment, the locking protrusion is provided for each of the two pairs of guide rollers, but the locking protrusion is provided only for the pair of guide rollers located at diagonal positions. Good too.

[Effects of the invention] With the above-described configuration, the present invention prevents the traveling body from falling at the intersection of the ceiling rails or turning horizontally to guide it into the desired ceiling rail. In addition to not causing any defects, and without requiring high assembly precision, it is possible to eliminate the running body from getting caught at intersections, and the effect is that the running body can run smoothly at all times. It will be done.

Further, since the locking protrusion for preventing excessive horizontal rotation is provided on the rail surface, the ceiling wall of the ceiling rail can be brought close to the upper end of the traveling roller without any difficulty. Therefore, an effect can also be obtained in that the vertical dimension of the ceiling rail can be reduced to the necessary minimum size.
