Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a suspension support device for suspending and supporting a movable wall for a partition 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 the ceiling rail via suspension rods at two locations, front and back, so that it can be moved along the ceiling rail. Such movable walls need to be moved in various ways for purposes such as storage, and some are configured so that they can pass through locations where ceiling rails are joined at right angles.

However, in this case, the suspension support device is, for example,
one ceiling rail having first rail parts on both sides of a continuous downward opening; and a continuous downward opening perpendicular to the downward opening, on both sides of the downward opening. a roller block that is provided with a pair of second rail parts and that is movably arranged and that suspends and supports the movable wall via a suspension rod that is inserted into the downward opening; A pair of tenth rollers are pivotally attached to two sides of the roller block and roll on the first rail part when the roller block runs within one of the ceiling rails, and a pair of tenth rollers are pivotably attached to the other two sides of the roller block. It is known that the roller block includes a pair of 20th rollers that roll on the second rail portion when the roller block runs within the other ceiling rail.

[Problems to be Solved by the Invention] By the way, in such a configuration, rotating rollers and sliders are provided at the four corners of the roller block, and these are brought into rolling or sliding contact with the side wall of the ceiling rail. This allows the roller block to run within the ceiling rail without turning horizontally.

However, with such a configuration, when the roller block reaches the intersection of the ceiling rails, the rotating rollers and sliders cannot roll or slide into contact with the side walls of the ceiling rails. Therefore, the roller block may turn horizontally at this intersection, resulting in a problem that it becomes unable to move into any of the ceiling rails.

As a measure to deal with such a problem, support balls that roll and support the lower surface of the roller block are provided 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 roller block. Guide grooves having a partially arcuate cross section that are engaged with are provided in a lattice pattern, and the engagement of these guide grooves with each of the support balls prevents the roller block from horizontally turning at the intersection of the ceiling rails. Things have been developed to prevent this.

However, with this configuration, if the roller block is not assembled in such a way that when the roller block is positioned at the intersection, the four support balls described above are accurately positioned at each intersection of the grid-shaped guide grooves, The load acting on the roller block forces the support ball against the deviated portion of the partially arcuate guide groove, and as a reaction, pivoting forces and other harmful forces act on the roller block. Therefore, smooth operation of the roller block 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 the second ceiling of both boxes. Problems tend to occur when moving along the rail in the thickness direction. That is, in such a case, if the intersections of the four support balls and the guide grooves of the roller block do not match accurately at each intersection of the first ceiling rail and the second ceiling rail, the movable wall It is not possible to smoothly guide both roller blocks, which suspend and support both ends of the box, into the ceiling rails of both boxes 2 at the same time. Therefore, 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 employs the following configuration.

That is, the suspension support device for a movable wall for a partition according to the present invention includes one ceiling rail comprising a pair of first rail parts on both sides of a continuous downward opening, and the downward opening. the other ceiling rail having orthogonal continuous downward openings and a pair of second rail sections on both sides of the downward opening; A roller block that suspends and supports a movable wall via a suspension rod inserted through a facing opening, and a roller that is pivotally attached to this roller block and rolls on the first rail portion or the second rail portion. The present invention is characterized in that a rotation preventing means for preventing horizontal rotation of the roller block by magnetic force is provided between the intersecting portion of both ceiling rails and the roller block.

[Function] With such a configuration, even if the roller block tries to horizontally turn at the intersection of the ceiling rails, the turning movement is blocked by the magnetic force induced by the turning prevention means. Therefore, it is possible to prevent the occurrence of a phenomenon in which the roller block turns and becomes unable to advance into any of the ceiling rails.

The horizontal rotation prevention action by the rotation prevention means is as follows:
Because it does not rely on contact and locking relationships between members, it is operated by magnetic force that allows force to be transmitted without contact.
The smooth operation of the roller block is no longer hindered due to slight misalignment of the mounting position, as in the above-mentioned engagement relationship between the support ball and the guide groove. Therefore, high accuracy is not required in the assembly positions of various parts.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

In addition, at the intersection of one ceiling rail 1 and the other ceiling rail 2, the ceiling wall 1 of each ceiling rail 1.2
3.23 has been removed, and the cross-shaped top plate 9 made of non-magnetic material such as aluminum material is the top wall 13.
．． It is placed flush with 23. As shown in FIG. 3, this top plate 9 is fixed to the side wall 14.24 of the ceiling rail 1.2 by a channel material 91.

The roller block 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 10th roller 6 is rotatably mounted on one of the two opposing sides of the roller block 5, and a 20th roller 7 is rotatably mounted on the other two opposing sides. Note that two roller blocks 5 are provided for each movable wall 4. When this roller block 5 travels within one of the ceiling rails 1, the 10th roller 6 rolls on the first rail portion 12 with the 20th roller 7 floating. When traveling on the other ceiling rail 2, the 20th rail 7 rolls on the second rail portion 22 with the 10th rail 6 floating.

Rotating rollers 51 are provided at the four corners of this roller block 5.

It is installed using. The rotating roller 51 has its outer periphery projected outward from the outermost surface of the roller block 5, so that it can come into rolling contact with the inner surface of the side wall 14.24 of the ceiling rail 1.2. And these rotating rollers 51
The height position of the lower surface is set to be the same as or slightly higher than the horizontal flat part 54 formed on the lower surface 5a of the roller block 5.

In addition, the four corners of the intersection of the ceiling rail 1.2, specifically, the parallel running track of the 10th-rail 6 and the 20th-
Two pairs of non-directional rotary support members, for example, support balls 83, are provided at diagonal corner positions of a rectangular area in plan view surrounded by the parallel running tracks of the rough. Specifically, a support ball 83 is rotatably held on the upper surface of the central bent portion 8C of each connection support member 8. The upper end portions of the support balls 83 protrude above the upper surface of the connection support member 8, so that the lower flat portion 54 of the roller block 5 located at this intersection can be supported in rolling contact by these support balls 83. I have to. That is, the roller block 5 passing through this intersection is held by these support balls 83 at approximately the same height position as when it is traveling within the ceiling rail 1.2.

Furthermore, a turning prevention means 10 is provided between the intersection of the two ceiling rails 1.2 and the roller block 5. The rotation prevention means 10 includes upper magnets 1011 to 1014 provided at the intersections of the ceiling rails 1.2, and a lower magnet 102 provided on the upper surface 5b of the roller block 5.
~1024. In detail, upper magnet 1
011 to 1014 are held by a holder 103 made of a non-magnetic material fixed to the ceiling plate 9 and arranged in a cross shape along the center line of the ceiling rail 1.2, and the lower end thereof is connected to the ceiling. It penetrates through the plate 9 and is exposed on the lower surface 9a of the top plate 9. These upper magnets 1011 to 1014 have an N pole and an S pole on both upstanding sides, and yokes 10IN and 101 are attached to both poles, respectively. on the other hand,
The lower magnets 102 to 1024 are connected to the roller block 5.
It is embedded and fixed in a holding plate 105 made of a non-magnetic material, which is attached to the upper surface 5b using a screw member 104. Note that these lower magnets 1021 to 1024 are also attached to the ceiling rail 1.
2, and their upper ends are exposed on the upper surface of the holding plate 105. These lower magnets 102, - 1024 also have N on their standing sides.
It has a pole and a south pole, and a yoke 102 is attached to both poles.
N and 102s are attached respectively. As shown in FIG. 4, the upper magnets 1014 and 1013 arranged along the center line of the first ceiling rail 1 have, for example, an N pole on the left side of the figure and an S pole on the right side of the figure. Yes, also the first
The lower magnet 1020. is arranged parallel to the ceiling rail 1.
1023 is set so that the left side in the figure is the S pole and the right side in the figure is the N pole. Further, the upper magnets 101□, 1014 arranged along the center line of the second ceiling rail 2 have, for example, an N pole on the upper side in the figure and an S pole on the lower side in the figure, and The lower magnets 102□ and 1024 arranged parallel to the ceiling rail 2 are set so that the upper side in the figure is the S pole and the lower side in the figure is the N pole.

With this configuration, the flat portion 54 formed on the lower surface 5a of the roller block 5 is supported by the support ball 83 at the intersection of the ceiling rails 1.2, so that the roller block 5 is at the intersection. Even if it reaches n, the 10th-
The rail 6 and the 20th rail 7 do not fall into the downward opening 1 a s 2 a of the ceiling rail 1.2. Since this support ball 83 is non-directional and can roll in all directions, the roller block 5 at the intersection n can be guided into any ceiling rail 1.2 depending on the degree of force applied. . Moreover, when the roller block 5 reaches the intersection n of the ceiling rail 1.2, the upper magnets 1011 to 1014 fixed to the top plate 9 and the lower magnets 102 to 1024 provided to the roller block 5 are vertically moved. The yoke 101 attached to the N pole of the upper magnets 101□-1014 and the lower magnets 1021-1024
The yokes 1025 attached to the S poles of the upper magnets 101 to 1014 face each other in close proximity, and the yokes 102N attached to the N poles of the lower magnets 102 to 1024 will be in close proximity to each other.

Therefore, even if the roller block 5 tries to horizontally turn at the intersection n, the yoke 101N and the yoke 10
2s and between the yoke 101s and the yoke 102N, the rotational movement is prevented.

Therefore, it is possible to prevent the occurrence of a problem in which the roller block 5 turns and becomes unable to advance into any of the ceiling rails 1.2.

Moreover, the above-described rotation prevention action by the rotation prevention means 10 does not rely on the contact relationship between members, but is performed based on magnetic force that allows force to be transmitted without contact. Therefore, each magnet 101, ~1014.1021~
Even if there is some error in the assembly position of 1024, the running of the roller block 5 will not be hindered. Further, the support ball 83 is connected to the flat portion 54 of the roller block 5.
Even if there is some deviation in the assembly position of the support balls 83, this will not affect the running of the roller block 5 in any way. Therefore, the roller block 5
The smooth running of the vehicle can be ensured.

It should be noted that the rotation prevention means is not limited to the above-mentioned means as long as magnets are arranged so as to prevent the horizontal rotation of the roller block at the intersection of the ceiling rails by magnetic force. However, if the configuration is as in the embodiment described above, the following effects can be obtained. That is, in the embodiment described above, when the roller block 5 advances from the intersection n into the first ceiling rail 1, the magnetic attraction relationship between the upper magnets 101□, 1024 and the lower magnets 102□, 1024 is maintained. When the roller block 5 is cut off, the roller block 5 moves, and when the magnetic attraction relationship is cut off, the upper magnet 1011.1013 and the lower magnet 1021.102
3 maintains a close relationship of mutual attraction. Therefore, the roller block 5 moves from the intersection n to the first ceiling rail 1.
There will be no problems such as turning horizontally immediately after escaping inward. Similarly, when the roller block 5 advances from the intersection n into the second ceiling rail 2, the upper magnet 101.
．． 1023 and lower magnet 102. ．． The roller block 5 moves by cutting off the magnetic attraction relationship with the upper magnet 1023.
The lower magnets 01□, 1014 and the lower magnets 102□, 1024 maintain a relationship in which they are close to each other and attract each other. Therefore, a problem such as horizontal turning immediately after the roller block 5 escapes from the intersection n toward the inside of the second ceiling rail 2 does not occur. In such a device, since the roller block 5 can be stopped at the intersection n of the ceiling rails 1 and 2 in a controlled manner by magnetic force, it is also convenient when changing the course of the roller block 5 by 90 degrees.

Furthermore, in the above embodiment, the case where one ceiling rail and the other ceiling rail cross each other was explained.
The present invention connects one ceiling rail and the other ceiling rail to L
It can be similarly applied to the case where they intersect in the shape of a letter or a T-shape.

[Effects of the Invention] Since the present invention has the above configuration, the inconvenience that the roller block horizontally turns at the intersection of the ceiling rails and cannot move properly can be solved by regulating the posture of the roller block using magnetic force. It is possible to provide a suspension support device for a partition movable wall, which can effectively prevent the above-mentioned problems and ensure smooth operation of the roller block without requiring high assembly precision.
