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 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,
One ceiling rail having a first rail part on both sides of a continuous opening, and a second rail part having a continuous opening perpendicular to the opening and forming a pair on both sides of the opening. The other ceiling rail and
a roller block that is movably disposed within the ceiling rail and suspends and supports the movable wall via a suspension rod that is inserted through the opening; When the roller block runs within one of the ceiling rails, the first
a pair of first rollers that roll on the rail portion; and a pair of rollers that are pivoted on the other two sides of the roller block and roll on the second rail portion when the roller block runs within the other ceiling rail. A device comprising a pair of second rollers is known.

[Problems to be Solved by the Invention] By the way, with such a structure, when the roller block reaches the intersection of the ceiling rails, the first roller drops a small amount into the opening of the other ceiling rail. At the same time, the second roller falls into the opening of the one ceiling rail by a certain amount. From this state, if a force is applied to the roller block in the direction along one of the ceiling rails via the suspension rod, the first roller will ride on the first rail part, and the other When a force is applied in a direction along the ceiling rail, the second roller rides on the second rail. However, if the force is uneven, the roller block may turn in the horizontal direction, causing a problem that the roller block cannot move into any of the ceiling rails.

In addition, in the conventional type, the first rail part and the second rail part of the ceiling rail are joined by directly abutting each other in a perpendicular state, and even at the intersection, the opening through which the suspension rod passes is the first rail part. and the second rail portion. Therefore, the rollers of the roller block that have reached the intersection fall between the edges of the opening formed between the first rail part and the second rail part. However, since this type of ceiling rail is often made of lightweight materials such as extruded aluminum, the opening formed by the first rail section and the second rail section at the intersection If the roller of the roller block repeatedly falls between the opening edges, the opening edge of the opening is likely to be deformed by the impact, and the amount of falling may gradually increase. When this wear and tear becomes noticeable, a larger impact will occur when passing through an intersection, making it impossible to smoothly operate the moving wall and requiring the entire ceiling rail to be replaced. become.

In addition, with such a configuration, when the roller block runs, it is in a two-wheel running state when moving within any of the ceiling rails. Moreover, the roller block and the suspension rod are generally connected so as to be swingable in order to prevent excessive stress from being repeatedly applied to the members. Therefore, the running roller block tends to swing vertically about the axes of the pair of rollers on which the load is applied. As a result, a problem arises in that smooth movement of the movable wall is hindered.

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 partition wall according to the present invention has a pair of first
one ceiling rail comprising a rail portion; the other ceiling rail comprising a continuous opening perpendicular to the opening and a pair of second rail portions on both sides of the opening; a connecting support member having an L-shape in plan view, which is provided at an intersection of the ceiling rails and connects the first rail part and the second rail part in a positioning state; A roller block that suspends and supports the movable wall through a suspension rod inserted through the wall, and a roller block that is pivoted on two opposing sides of one of the roller blocks and is attached to the wall when the roller block runs within one of the ceiling rails. A pair of first rollers that roll on the first rail part, and a pair of first rollers that are pivoted on two opposing sides of the other roller block, and when the roller block runs within the other ceiling rail, the second rail part A main convex part and a sub-convex part are provided at substantially diagonal positions sandwiching the center of the roller block, and the second roller block is provided with a pair of second rollers that roll on the top of the roller block, and a main convex part and a sub-convex part are provided at substantially diagonal positions sandwiching the center of the roller block. A first roller block is provided on the ceiling wall surface of the section to engage with the main convex portion and guide the roller block in the direction along one of the ceiling rails.
A second groove that engages the main protrusion and guides the roller block along the other ceiling rail is provided, and a sub-protrusion that is shorter than the main protrusion is provided. The roller block is brought into contact with or close to the top wall surface, and the opening edge of the opening into which the roller of the roller block falls when it reaches the intersection is formed by each of the connection support members.

[Function] With this configuration, when the roller block approaches the intersection of the ceiling rails or leaves the intersection, the main convex portion provided at a position off the center of the roller block moves into the first groove. Alternatively, it will be engaged with and guided by the second groove. Therefore, it is possible to prevent the roller block from turning horizontally at the intersection of the ceiling rails.

In addition, when the roller block runs, it is running on two wheels no matter which ceiling rail it moves within, so as mentioned above, it tries to make vertical swing motion around the axis of the roller. However, in the present invention, the main convex part and the sub-convex part of the roller block are located on both sides of the axis of the roller. Therefore, when the roller block tries to swing its head in the vertical direction, either the main convex part or the sub-convex part comes into contact with the ceiling wall surface of the ceiling rail. Therefore, the swinging motion of the roller block is prevented and the roller block runs smoothly.

Further, in the present invention, since the opening edge of the opening into which the roller of the roller block that has reached the intersection falls is formed by a connecting support member, the impact caused by the roller acts on this connecting support member. Since this connecting support member is separate from the ceiling rail, it is possible to use a material different from that of the ceiling rail, which has a narrow range of material selection due to the demand for weight reduction. Therefore, by constructing the connecting support member from a material having impact resistance and wear resistance, it is possible to prevent or suppress the deformation of the opening edge described above. Furthermore, even if the edge of the connecting support member should become deformed to some extent due to long-term use, the problem can be resolved by replacing only the connecting support member. , there is no need to replace the entire ceiling rail.

[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 opening and an opening 2a perpendicular to the opening 1a. The other ceiling rail 2 with
and a roller block 5 which is movably disposed within the ceiling rails 1 and 2 and suspends and supports the movable wall 4 via suspension rods 3 inserted through the openings 1a and 2a.
and a first and second roller 6, 7 which are pivotally attached to the roller block 5.

The ceiling rails 1 and 2 are buried in the ceiling of a building, and have bottom walls 11 and 21 having continuous openings 1a and 2a in the center exposed on the ceiling surface.
In one ceiling rail 1, there is a bottom wall 1.
A pair of first rail portions 12 parallel to the opening portion 1a are integrally provided on both sides of the opening portion 1a. Further, inside the second ceiling rail 2, a second rail portion 22 forming a pair parallel to the bottom wall 21 is provided at the opening 2.
They are integrally provided on both sides of a. 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 8a is connected to the bolt 8.
1 and a plate-shaped nut 82 between the first rail part 12 of one ceiling rail 1 and the bottom wall 11, and the other end side 8b is fixed using a bolt 81 and a plate-shaped nut 82. and is fixed between the second rail portion 22 of the other ceiling rail 2 and the bottom wall 21. The upper surface of each connection support member 8 is set flush with the upper surfaces of the first and second rail parts 12 and 22, and the opening 1a of one ceiling rail 1 and the other ceiling are located between the central bent part 8c. A criss-crossing portion with the opening 2a of the rail 2 is formed. In other words, the opening edges 1 of the openings 1a, 2a into which the first and second rollers 6, 7 of the roller block 5 that have reached the intersection n fall.
b and 2b are respectively formed by the central bent portion 8c of each of these connecting support members 8. In addition, at the intersection between one ceiling rail 1 and the other ceiling rail 2, the ceiling walls 13 and 23 of each ceiling rail 1 and 2 are cut out, and the cross-shaped ceiling plate 9 is attached to the ceiling wall. 13 and 23. As shown in FIG.
It is fixed at 4,24.

The roller block 5 is a metal 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 roller 6 is rotatably mounted on one of the two opposing sides of the roller block 5, and a second 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 ceiling rail 1, the first roller 6 rolls on the first rail section 12 with the second roller 7 floating. When traveling on the other ceiling rail 2, the second roller 7 rolls on the second rail portion 22 with the first roller 6 floating.

A rolling ball 50 as a main convex portion and a slider 51 as a sub convex portion are provided at diagonal positions sandwiching the center of the roller block 5 so as to project upward. That is, at the corner of the roller block 5,
A seat 52 with a screw hole 52a and a holding hole 53a
A catch seat 53 having a diameter is integrally formed. A ball holder 54 having a bolt portion 54a is screwed onto the seat 52. The ball holder 54 rotatably holds the five rolling balls. The rolling ball 50 is held with its upper end portion protruding from the upper surface of the ball holder 54, and the protruding portion is inserted into the first groove 9.
2 or the second groove 93.

The first groove 92 and the second groove 93 are formed on the ceiling wall surface at the intersection of the ceiling rails 1 and 2, that is, on the lower surface 9a of the ceiling plate 9. That is, the first groove 92 has an arcuate cross section with which the upper end portion of the rolling ball 50 can rollably engage, and guides the roller block 5 in the direction along one of the ceiling rails 1. It is formed so that it can be done. The second groove 93 is formed by the rolling ball 50.
The upper end portion thereof has an arcuate cross section that can be engaged with in a rollable manner, and is formed so as to be able to guide the roller block 5 in a direction along the other ceiling rail 2. In this embodiment, an auxiliary first groove 15 that is continuous with the first groove 92 is formed in the ceiling wall surface 13a of the ceiling wall 13 of one ceiling rail 1, and an auxiliary first groove 15 that is continuous with the first groove 92 is formed in the ceiling wall surface 13a of the ceiling wall 13 of one ceiling rail 1. An auxiliary second groove 25 that is continuous with the second groove 93 is formed in the top wall surface 23 a of the top wall 23 .

The first groove 92 and the second groove 93
The depth dimension is at the intersection n of ceiling rails 1 and 2,
The size is set larger than the size at which the roller block 5 falls downward.

On the other hand, the slider 51 is formed by integrally molding, for example, a cylindrical base end 51a and a hemispherical distal end 51b, and is made of a material with good self-lubricating properties such as fluorine resin. . The base end 51a of the slider 51 is fitted or press-fitted into the holding hole 53a, and the distal end 51a is fitted or press-fitted into the holding hole 53a.
1b protrudes upward, and its tip 5
1b can be engaged with the top plate 9 and the top wall surfaces 9a, 13a, 23a of each ceiling rail 1, 2.

With such a configuration, the rolling balls 50 of the roller block 5 heading from one ceiling rail 1 toward the intersection n will touch the top plate 9 before the intersection n.
It is engaged with and guided by the first groove 92 provided in the. Further, the rolling balls 50 of the roller block 5 heading from the other ceiling rail 2 toward the intersection n are guided by engaging with the second groove 93 provided in the top plate 9 before the intersection n. In either case, at the intersection n, the second roller 7 falls slightly between the opening edges 1b of the opening 1a of one ceiling rail 1, and the first roller 6 falls into the opening of the other ceiling rail 2. The roller block 5 falls between the opening edges 2b of the portion 2a and stops. When a force is applied to the roller block 5 in the direction along one of the ceiling rails 1 from this state, the first roller 6 moves toward the opening edge 2b.
The rolling ball 50 rides on and advances onto the first rail portion 12, but at this time, the rolling ball 50 engages with the first groove 92 and is guided. Furthermore, when a force is applied to the roller block 5 at the intersection n in the direction along the other ceiling rail 2, the second roller 7 moves toward the opening edge 1b.
The rolling ball 50 rides on the ball and advances onto the second rail portion 22, but at this time, the rolling ball 50 engages with the second groove 93 and is guided.

Therefore, the roller block 5 is connected to the ceiling rail 1,
It is possible to prevent turning in the horizontal direction at the intersection of the two. That is, the rolling ball 50
is provided at a position off the center of the roller block 5, so if this rolling ball 50 is guided by the first and second grooves 92 and 93, the roller block 5 can horizontally rotate around its center. This means that it can be prevented. Therefore, when the roller block 5 passes through the intersection n of the ceiling rails 1 and 2, its direction is suddenly deflected and
2 can be prevented from occurring, and the movable wall 4 can be easily and reliably moved along a desired route.

Furthermore, when the roller block 5 is traveling within the ceiling rails 1 and 2, the rolling balls 50 and the slider 51 cooperate to prevent the roller block 5 from swinging in the vertical direction. It turns out. That is, the vertical swinging motion of the roller block 5 tends to occur around the axis of the roller 6 or 7 on the side on which the load is applied, as described above. On the other hand, since the rolling balls 50 and the sliders 51 are provided at diagonal positions sandwiching the center of the roller block 5, they are located on both sides of the axis. Therefore, when the roller block 5 tries to swing its head in the vertical direction, the rolling balls 50 or the slider 51 move toward the ceiling rail 1,
It is pressed against the top wall surfaces 13a, 23a of the top walls 13, 23 of No. 2, and its swinging motion is prevented. Therefore, the roller block 5 runs smoothly within the ceiling rails 1 and 2 without making unnecessary movements, and the movable wall 4 can be moved easily.

In addition, in the above embodiment, the main convex part is a rolling ball and the sub-convex part is a slider, but the main convex part and the sub-convex part are both rolling balls, or both are sliders. Various modifications can be made without departing from the spirit of the present invention.

In addition, there is no need to provide a groove on the ceiling wall surface other than the intersection of the ceiling rails, where the main convex part engages.
Although the effects described above can be obtained, if grooves are provided in areas other than the intersections as in the illustrated embodiment, it will be more reliable that the roller block running inside the ceiling rail will be deflected in the horizontal direction. can be prevented.

Furthermore, the present invention can be similarly applied to a structure in which the roller does not fall into the opening at an intersection. For example, a ball or the like may be placed at a corner diagonal position within a rectangular area in plan view surrounded by the parallel running track of the first roller and the parallel running track of the second roller at the intersection of the ceiling rails. A pair of non-directional rotary support members are disposed, and the flat lower surface of the roller block located at the intersection is supported by the rotary support members in rolling contact so that the roller block is at approximately the same height as when the roller block is traveling. It is conceivable that the device be constructed so that it can be held in a fixed position.

Further, in the above embodiment, the case where one ceiling rail and the other ceiling rail are crossed in a cross is explained, but in the present invention, one ceiling rail and the other ceiling rail are arranged in an L-shape or a T-shape. The same application is possible even when the lines intersect with each other.

[Effects of the invention] Since the present invention has the above-described configuration, it is possible to prevent the inconvenience of the roller block horizontally turning at the intersection of the ceiling rails and making it impossible to proceed properly with a simple configuration. Moreover, it is possible to provide a suspension support device for a movable wall for a partition, which can also solve the problem of a roller block running in a ceiling rail swinging its head in the vertical direction.

In addition, in the present invention, the first rail part and the second rail part are positioned and connected by a connecting support member that is L-shaped in plan view, so that it is possible to effectively prevent a large step from occurring on the rail surface at the intersection part. It can be prevented. Moreover, since the opening edge of the opening into which the roller of the roller block falls when it reaches the intersection is formed by these connecting support members,
The material of the opening edge can be made different from the material of the ceiling rail. Therefore, it is possible to improve the impact resistance and abrasion resistance of the opening edge at the roller drop part without increasing the weight or price of the entire ceiling rail, and prevent or suppress deformation of the opening edge. be able to. Furthermore, even if deformation or wear occurs on the opening edge due to long-term use, there is no need to replace the entire ceiling rail, and the problem can be easily dealt with by simply replacing the connecting support member.
