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.

[Conventional technology]

BACKGROUND ART Recently, movable partition walls are often installed in hotel banquet halls, offices, etc., which 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.

[Problem that the invention attempts to solve]

By the way, in such a structure, when the roller block reaches the intersection of the ceiling rails, the first roller falls a little into the opening of the other ceiling rail, and the second roller falls into the opening of the other ceiling rail. A small amount will fall into the opening of the ceiling rail. 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 portion. However, if the force is uneven, the roller block may turn in the horizontal direction, resulting in 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 problems]

In order to achieve the above objects, 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 the other two opposing sides of the roller block so that when the roller block runs within the other ceiling rail, the roller block rolls on the second rail. a pair of second rollers that roll on the roller block, and a slider is provided at a diagonal corner position of the roller block to project upward, and a slider is provided at a diagonal corner position of the roller block, and a slider is provided at a diagonal position at a corner of the roller block, and a slider is provided at a diagonal corner position of the roller block, and a Two parallel first grooves are provided on the wall surface to engage with the slider and guide the roller block along one of the ceiling rails; and two parallel first grooves that engage with the slider to guide the roller block along the other ceiling rail. two parallel second concave grooves are provided for guiding in the direction along the intersection, and the opening edges of the opening into which the rollers of the roller block fall when they reach the intersection are formed by the respective connection support members. do.

[Effect]

With this configuration, when the roller block approaches or leaves the intersection of the ceiling rails, the slider provided at the diagonal corner position moves into the two parallel first grooves. Alternatively, it is engaged with and guided by two parallel second grooves. Therefore, it is possible to reliably prevent the roller block from turning horizontally at the intersection of the ceiling rails.

In addition, when the roller block runs on any of the ceiling rails, it is running on two wheels, so it tries to make a vertical swinging motion as described above, but the present invention Since a slider is provided at a diagonal position at a corner of the roller block, when the roller block tries to swing its head in the vertical direction, the slider comes into sliding contact with the top 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〕

An embodiment of the present invention will be described below 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 cross-intersecting 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 pair of sliders 51 are provided at diagonal corners of the roller block 5 so as to project upward. That is, at the corner of the roller block 5,
Seats 52 having holding holes 52a are integrally formed, and the slider 51 is held in the holding holes 52a of these seats 52. Slider 51
has a cylindrical base end 51a and a hemispherical tip 5.
1b, and is made of a material with good self-lubricating properties, such as fluorocarbon resin. The base end 51a of the slider 51 is fitted or press-fitted into the holding hole 52a, and the tip 51b protrudes upward. It can be engaged with the groove 92 or a pair of parallel second grooves 93.

The first groove 92 and the second groove 93 are formed in a grid pattern 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 in which the tip end 51b of the slider 51 can be slidably engaged, and guides the roller block 5 in the direction along one of the ceiling rails 1. They are formed parallel to each other. The second groove 93 has an arcuate cross section in which the tip end 51b of the slider 51 can be slidably engaged, and can guide the roller block 5 in the direction along the other ceiling rail 2. They are formed parallel to each other. In this embodiment, an auxiliary first groove 15 that is parallel to and continuous with the first groove 92 is formed on the lower surface of the ceiling wall 13 of one ceiling rail 1, and a parallel first groove 15 is formed on the lower surface of the ceiling wall 13 of one ceiling rail 1. A parallel auxiliary second groove 25 that is continuous with the second groove 93 is formed on the lower surface 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.

With such a configuration, the slider 51 of the roller block 5 heading from one ceiling rail 1 toward the intersection n engages with the first groove 92 provided in the top plate 9 before the intersection n and is guided. be done. Also,
The slider 51 of the roller block 5 heading from the other ceiling rail 2 toward the intersection n is 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 rides on the opening edge 2b and advances onto the first rail part 12, but at this time, In this case, the slider 51 is engaged with and guided by the first groove 92. Furthermore, when a force is applied to the roller block 5 at the intersection n in a direction along the other ceiling rail 2, the second roller 7 rides on the opening edge 1b and advances onto the second rail portion 22; At this time, the slider 51 is engaged with and guided by the second groove 93.

Therefore, the roller block 5 is fixed to the ceiling rail 1,
This can reliably prevent the roller block 5 from turning horizontally at the intersection n of the ceiling rails 1 and 2. Therefore, when the roller block 5 passes through the intersection n of the ceiling rails 1 and 2, it is possible to prevent the roller block 5 from suddenly changing direction and being unable to be smoothly guided to either of the ceiling rails 1 and 2, and it is possible to easily and reliably move the moving wall 4 along the desired route. Moreover, since a large load based on the gravity of the moving wall 4 is not applied to the slider 51, the frictional resistance when the slider 51 slides is not very large.

Furthermore, when the roller block 5 is traveling within the ceiling rails 1 and 2, the slider 51 slides into contact with the ceiling walls 13 and 23 of the ceiling rails 1 and 2, causing the roller block 5 to swing in the vertical direction. This will prevent 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 slider 51 is provided at a diagonal corner of the roller block 5, it is located on both sides of the axis. Therefore, when the roller block 5 tries to swing its head in the vertical direction, the slider 5 located at either the front or rear
1 will be pressed against the ceiling walls 13, 23 of the ceiling rails 1, 2, and its swinging motion will be 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.

Note that the shape of the slider may be, for example, as shown in FIG. 4 or FIG. 5. That is, the slider 151 shown in FIG. 4 has a conical tip 151b. Therefore, in this case, the first groove 192 and the second groove 193 are made to have a substantially triangular cross section. The slider 251 shown in FIG. 5 has a tip 251b having a cylindrical shape. Therefore, in this case, the first groove 292 and the second groove 293 are made to have a rectangular cross section. In addition, the shape of the slider can be modified in various ways, and the base end can be made into a prismatic shape, or the whole can be made into a hollow body shape. It is also possible to provide two pairs of sliders and position them at the four corners of the roller block.

In addition, the above-described effects can be obtained without providing a groove with which the slider engages on the ceiling wall surface other than the intersection of the ceiling rails. By providing the groove, it is possible to more reliably prevent the roller block running within the ceiling rail from being deflected in the horizontal direction.

Furthermore, 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.

[Effect of idea]

Since the present invention has the above configuration, it is possible to reliably prevent the inconvenience of the roller block turning horizontally at the intersection of the ceiling rails and making it impossible to proceed properly with an extremely simple configuration. Furthermore, it is possible to provide a suspension support device for a movable wall for a partition, which can also solve the problem of the roller block running in the ceiling rail swinging its head in the vertical direction. In addition, in this invention,
Since the first rail part and the second rail part are positioned and connected by the connecting support member having an L-shape in plan view, it is possible to effectively prevent a large step from occurring on the rail surface at the intersection. Furthermore, since the opening edge of the opening into which the roller of the roller block falls when reaching 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 where the roller falls, without increasing the weight or price of the entire ceiling rail, and prevent or suppress deformation of the opening edge. can do. 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.
