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, respectively, so that it can be moved along the ceiling rail. Such a movable wall needs to be moved in various ways for storage etc.
Some are constructed so that they can pass through where the ceiling rails are 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 moving wall has been developed that is much taller than a human being, and in order to move such a moving wall, the lower half of the wall must be moved. You have no choice but to press the button. 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 extremely high assembly accuracy is required.

In order to solve these problems, this invention
The flat part formed on the lower surface of the traveling body is supported by a support ball, and a locking protrusion is provided at a required location on the lower surface of the ceiling wall at the intersection of the ceiling rails, and this locking protrusion It has been considered to prevent excessive horizontal turning of the traveling body by locking the guide rollers or special protrusions of the traveling body at the portion.

However, such a locking protrusion needs to be provided so as to protrude from the lower surface of the ceiling rail without interfering with the normal movement of the traveling body. Therefore, when this locking protrusion is attached to the lower surface of the ceiling wall using a fastener such as a bolt, the attachment portion becomes bulky. Therefore, there is a problem in that the entire ceiling rail has to be large in vertical dimension. Further, it is often difficult to fasten components to the ceiling wall of the ceiling rail from the bottom side with bolts or the like, and there is a problem in that the order in which the ceiling rails are joined is severely restricted.

The present invention aims to eliminate all such problems.

[Means for Solving the Problems] In order to achieve the above objects, 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 upper 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. The outer circumferential surface of the guide roller or the A locking protrusion for preventing excessive turning that locks a protrusion protruding from an upper surface corner of the traveling body, the locking protrusion being suspended from the lower surface of the substrate. and allowing the locking protrusion to penetrate the ceiling wall and protrude into the ceiling rail,
It is characterized in that the substrate is fixed to the upper surface of the ceiling wall by a fastener.

[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 top 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 or special protrusion of the guide roller comes into contact with a locking protrusion protruding from the ceiling rail and is locked. Therefore, the traveling body can no longer 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, the guide roller may come into contact with the edge of the side wall as the traveling object moves in. Even if there is, the guide roller will be pushed inward as the traveling body moves forward. Moreover, since this guide roller is horizontally rotatable, it is retracted inward while keeping a specific part of its outer peripheral surface in contact with the edge of the side wall.
The traveling object will be smoothly corrected in direction and 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.

Moreover, the locking protrusion is suspended from the board, and is fixed to the ceiling rail by fixing the board to the upper surface of the ceiling rail. Therefore, no parts for securing the locking protrusion protrude from the lower surface of the ceiling rail. This locking protrusion can be attached from the top side of the ceiling wall.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 8.

As shown in FIGS. 1 and 2, this suspension support device for a movable wall for a partition consists of one ceiling rail 1 having a continuous downward opening 1a, and a ceiling rail 1 that is perpendicular to the downward opening 1a. It moves via the other ceiling rail 2 having a downward opening 2a and a suspension rod 3 which is movably disposed within the ceiling rails 1 and 2 and inserted into the downward openings 1a and 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, the joint ends of each of the ceiling rails 1 and 2 are cut to form the apex of a right triangle in plan view, and by abutting these joint ends, an intersection is formed. Four connecting support members 8 are arranged at the intersection, and these connecting support members 8 connect the first
The rail portion 12 and the second rail portion 22 are connected in a positioned manner. The connection support member 8 is an L-shaped metal fitting, and one end side 8a is fixed between the first rail part 12 of one ceiling rail 1 and the bottom wall 11 using a bolt 81 and a plate nut 82. At the same time, the other end side 8b is connected to a bolt 81 and a plate nut 82.
and the second rail part 2 of the other ceiling rail 2.
2 and the bottom wall 21. The upper surface of each connection support member 8 is connected to the first and second rail portions 12 and 22.
The downward opening 1a of one ceiling rail 1 is set flush with the upper surface, and the downward opening 1a of one ceiling rail 1 is located between the central bent part 8c.
and the downward opening 2a of the other ceiling rail 2 form a criss-crossing portion.

The traveling body 5 is a block whose outer shape is substantially rectangular in 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 of the ceiling rails 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 upper surface 5b 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 placed on the upper 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.

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 portions of the support balls 83 protrude above the upper surface of the connection support member 8, and these support balls 83 roll into contact with the flat portion 54 formed on the lower surface 5a of the roller block 5 located at this intersection. I'm trying to make it supportable. In other words, the traveling body 5 passing through this intersection is affected by these support balls 8.
3 so that it is held at approximately the same height position as when running on the ceiling rails 1 and 2.

Furthermore, locking protrusions 91 ₁ to 91 ₄ are provided at intersections between the ceiling rails 1 and 2 to prevent excessive horizontal turning of the traveling body. Each of the locking protrusions 91 ₁ to 91 ₄ has its inner surface 91a connected to the inner surface 14 of the side walls 14, 24 of the ceiling rails 1, 2.
24a, and its both ends 91b are located near the regular running track a of the guide rollers 51 ₁ to 51 ₄ . The positions of both ends 91b of these locking protrusions 91 ₁ to 91 ₄ 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 The turning position, that is, the guide rollers 51 ₁ to 5
1 ₄ axis b is the inner surface 14a, 24a of the side walls 14, 24 of the ceiling rails 1, 2 on which the traveling body 5 should travel.
The outer circumferential surface 51 of the guide rollers 51 1 to 51 4 is located at a position well before the point where the guide rollers 51 ₁ to 51 ₄ move outward.
The value is set such that a will come into contact with the corresponding locking protrusions 91 ₁ to 91 ₄ . In this embodiment, specifically, the guide rollers 51 ₁ to 51 ₄
The outer diameter of the running body 5 is approximately 1/1/1 of the length of one side of the traveling body 5.
4, and each of the locking protrusions 91 ₁
The end portion 91b of ~ ₉₁₄ is connected to the guide roller ₅₁₁ ~5.
1 ₄ as close as possible to the regular travel trajectory a. The structure for attaching the locking protrusions 91 ₁ to 91 ₄ to the ceiling rails 1 and 2 is as follows.
Each of the locking protrusions 91 ₁ to 91 ₄ is integrally suspended from the lower surface of the substrates 9 ₁ to 9 ₄ . Bolt holes 92 are bored in the substrates 9 ₁ to 9 ₄ , and through holes 93 corresponding to the cross-sectional shapes of the locking projections 91 ₁ to 91 ₄ are formed in the ceiling rails 1 and 2, and bolt holes 92 are formed in the ceiling rails 1 and 2 to accommodate the bolts. A screw hole 94 corresponding to hole 92 is provided. Then, the locking protrusions 91 ₁ to 91 ₄ are inserted into the through holes 93 from above.
A bolt 95 serving as a fastener is inserted through the bolt hole 92 of the board 9 ₁ to 9 ₄ to bring it into contact with the upper surface of the ceiling wall 13 or 23 of the ceiling rail 1 or 2.
By screwing them into the screw holes 94, the substrates 9 ₁ to 9 ₄ and the locking protrusions 91 ₁ to 91 ₄ are fixed to the top walls 13 and 23. However,
In the fixed state, the locking protrusions 91 ₁ to 91 ₄
Only the tip portions thereof protrude toward the lower surfaces of the ceiling walls 13, 23.

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 upper surface 5b is aligned with the side wall 1 of the ceiling rails 1 and 2 to be entered.
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 ₄ and are locked. Therefore, the traveling body 5 can no longer horizontally turn. Specifically, when the traveling body 5 turns at the intersection n, the guide roller 51 ₁ is located at the position shown in FIG. 8a.
51 ₄ are locked by the locking protrusions 91 ₁ to 91 ₄ . 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 ₃ and pressed inward. With,
The guide roller 51 ₄ on the front side in the traveling direction is guided by the corresponding locking protrusion 91 ₄ 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. 8b, the guide roller ₅₁₁ on the front side in the traveling direction contacts the edge 24b of the side wall 24 of the ceiling rail 2. 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 ₃ ,
91 ₄ . 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 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. 8c. 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
₁ to 91 ₄ and the side walls 14 and 24 are horizontally rotatable guide rollers 51 ₁ to 51 ₄ , so even when correcting the horizontal turning attitude of the traveling body 5, sliding of the members is prevented. 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
₁ to 91 ₄ , a relatively large clearance can be provided. 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 ₄ .

Furthermore, this thing has locking protrusions 91 ₁ to 91 ₄
Boards 9 ₁ to 9 ₄ arranged outside the ceiling rails 1 and 2
The locking protrusion 91 ₁
- 91 ₄ are passed through the ceiling walls 13, 23, and the substrates 9 ₁ - 9 ₄ are fixed to the upper surfaces of the ceiling walls 13, 23, so that the fixed portions are attached to the ceiling walls 13, 23. , 23 does not protrude from the bottom side at all.
That is, only the necessary locking protrusions 91 ₁ to 91 ₄ protrude from the lower surfaces of the top walls 13 and 23. Therefore, the possibility that the ceiling rail will have to have a large vertical dimension due to unnecessary protrusion is greatly reduced. In addition, since the locking protrusions 91 ₁ to 91 ₄ can be assembled from the outside of the ceiling rails 1 and 2, the assembly work is easy, and the intersecting portions of the ceiling rails 1 and 2 have no structure. It can be quickly and reliably attached to a predetermined position even if the

The shape of the locking protrusion is not limited to that of the embodiment described above, and for example, the shape of the locking protrusion is not limited to that of the embodiment described above.
It may be as shown in Figure 0. That is, the locking protrusion 19 shown in FIGS. 9 and 10
1 ₁ to 191 ₈ are pin-shaped, and the same or corresponding parts are given the same reference numerals as in the above embodiment, and the explanation thereof will be omitted. In this way, the locking protrusion 1
When making 91 ₁ to 191 ₈ pin-shaped,
The upper ends of the running rollers 6 and 7 and the guide rollers 51 ₁ ~
51 ₄ are set at substantially the same height position, and the running rollers 6 and 7 and the guide rollers 51 ₁ to 5
1 and ₄ in the space formed between the locking protrusions 1 and 4.
91 ₁ to 191 ₈ may be located.
In this way, the height of the entire running part including the guide rollers 51 ₁ to 51 ₄ and the running body 5 can be made as low as possible, so ceiling rails 1 and 2 with even smaller cross-sectional shapes can be used. It becomes possible to do so. As a locking protrusion that can reduce the height of the ceiling rails 1 and 2, the one shown in FIG. 11 can also be considered. That is, both end portions 291a of the locking protrusion 291 are located in a space formed between the running rollers 6, 7 and the guide roller 51, and the lower surface of the center is provided with the running rollers 6, 7. recess 29 to avoid interference with
1b is formed.

Further, when the locking protrusion is made into a pin-like structure, it may be configured as shown in FIG. 12. That is, the locking protrusions 391 ₁ to 391 ₈ shown in the figure
are suspended from substrates 309 ₁ to 309 ₄ spanning the first ceiling rail 1 and the second ceiling rail 2, respectively. Therefore, with such a structure, the boards 309 ₁ to 309 ₄ also serve as reinforcing members that connect the ceiling wall 13 of the first ceiling rail 1 and the ceiling wall 23 of the second ceiling rail 2. I will be in charge.

Furthermore, in the above embodiments, the outer circumferential surface of the guide roller is locked by the locking protrusion, but if the guide roller is provided on the lower surface side of the traveling body, the 13th It is also possible to have a structure as shown in the figure. That is, protrusions 451 ₁ to 451 ₄ made of rotating balls, sliders, etc. are provided at the four corners of the upper surface of the traveling body 405 to protrude upward, and these protrusions 451 are connected to the locking protrusions according to the embodiment described above. The traveling body 405 may be prevented from turning excessively horizontally at the intersection of the ceiling rails by being locked by the section.

[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 problems, the traveling body can be prevented from getting caught at intersections without requiring high assembly accuracy, and the traveling body can always run smoothly.

Moreover, since the locking protrusion can be attached from the outside of the ceiling rail, the bulk of the attachment part may require increasing the vertical dimension of the ceiling rail, making assembly difficult. This problem can be reliably resolved.
