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.
Some are designed to pass through where 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 traveling body presses the support ball against the deviated portion of the partially arcuate guide groove, and as a reaction, a turning force or other harmful force acts on the traveling body. 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. That is, in such a case, at each intersection of the first ceiling rail and the second ceiling rail,
If the intersections of the four support balls and the guide grooves of the traveling bodies do not match accurately, it will be impossible to smoothly guide both traveling bodies, which suspend and support both ends of the movable wall, into both second ceiling rails at the same time. Can not. 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 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 objects, the present invention adopts the following configuration. Namely, the present invention employs the suspension support of a movable partition wall according to the present invention. The device includes a pair of rail parts on both sides of a continuous downward opening, and a ceiling rail that is connected at right angles to each other, and a ceiling rail that is movably disposed within the ceiling rail and has a pair of rail parts on both sides of a continuous downward opening. a running body that suspends and supports the movable wall via a suspension rod inserted through the running body; a running roller that is pivoted to the running body and rolls on the rail portion; and a diagonal corner on the upper surface of the running body. a pair of guide rollers which are horizontally rotatably pivoted at a position and which roll into contact with the inner surface of a side wall of the ceiling rail when the traveling body travels within the ceiling rail to regulate the running posture of the traveling body; and the ceiling rail. a non-directional rotary support member provided at the intersection of the ceiling rails and rotatably supports the lower flat portion of the traveling body from below; and a non-directional rotation support member provided protruding from the ceiling wall surface at the intersection of the ceiling rail so that the axis of the guide roller is and a locking protrusion for preventing excessive turning that locks the outer peripheral surface of the guide roller to prevent the traveling body from horizontally turning until it is located outside the inner surface of the side wall of the guide rail to be entered. It is characterized by becoming.

[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 of the guide roller comes into contact with a locking projection provided on 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
The guide rollers are 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 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.

[Example] An embodiment of the present invention will be described below.

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.

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

A cross section is formed. In addition, at the intersection of one ceiling rail 1 and the other ceiling rail 2, the ceiling walls 13 and 23 of each of these ceiling rails 1 and 2 are cut out,
A cross-shaped top plate 9 is arranged flush with the top walls 13, 23. This top plate 9 is made of channel material (not shown) or the like to form the side walls 1 of the ceiling rails 1 and 2.
It is fixed at 4,24.

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 rotatably mounted on one of the two opposing sides of the running body 5, and a second running roller 7 is rotatably mounted on the other two opposing sides. There is.
Note that two traveling bodies 5 are provided for each moving wall 4. And, this running body 5 is
When traveling on one ceiling rail 1, the first traveling roller 6 rolls on the first rail part 12 with the second traveling roller 7 floating, and the When traveling within Rail 2,
The second running roller 7 rolls on the second rail portion 22 with the first running roller 6 floating.

Two pairs of guide rollers 51 ₁ to 51 ₄ are pivotally mounted at diagonal corner positions on the upper surface 5b of the traveling body 5 so as to be horizontally rotatable. 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 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 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.

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.
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, the guide roller ₅₁₁ on the front side in the traveling direction comes into contact with the edge 24b of the side wall 24 of 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 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 53 of the guide roller ₅₁₁ . Therefore, the posture of the traveling body 5 is further corrected, and as shown in FIG. 5c,
The user will enter the ceiling rail 2 in a normal posture. 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 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.

In addition, since the locking protrusions 91 ₁ to 91 ₄ are provided on the ceiling wall surface 9a, it is necessary to take into consideration the positional relationship with the downward openings 1a and 2a and the presence or absence of interference with the running rollers 6 and 7. There is no locking protrusion 91 ₁ ~
₉₁₄ can be made into a relatively free shape.

Note that the shape of the locking protrusion is not limited to that of the embodiments described above, and for example,
It may be as shown in the figure. That is,
Locking protrusions 191 ₁ to 191 shown in FIGS. 6 and 7
Reference numeral ₁₉₁₄ is a pin-shaped member, and the same or corresponding parts are given the same reference numerals as in the previous embodiment, and the explanation thereof will be omitted. In this way, the locking protrusion 191
₁ to 191 ₈ are pin-shaped, the upper ends of the running rollers 6 and 7 and the guide rollers 51 ₁ to 51 ₄
The locking protrusions 191 1 to 191 1 are set at substantially the same height position as the upper surface, and the locking protrusions 191 ₁ to 191 ₁ are located in the spaces formed between the running rollers 6 and 7 and the guide rollers 51 1 to 51 ₄ .
191 ₈ may be located. In this way, the guide rollers 51 ₁ to 51 ₄ and the traveling body 5
Since the height of the entire running portion including the rails can be made as low as possible, it is possible to use ceiling rails 1 and 2 with small cross-sectional shapes. As a locking protrusion that can reduce the height of the ceiling rails 1, 2, the one shown in FIG. 8 can also be considered. That is, this locking protrusion 291
Both end portions 291a are located in the space formed between the running rollers 6, 7 and the guide roller 51, and there is a groove on the lower surface of the center to avoid interference with the running rollers 6, 7. A recess 291b is formed.

[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. A moving wall for partitions that does not cause any defects, does not require high assembly precision, can eliminate the running body from getting caught at intersections, and allows the running body to run smoothly at all times. It is possible to provide a suspension support device.
