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.
It is constructed so that it can pass through the place where the ceiling rail is joined at right angles.

However, as a suspension support device in this case,
A ceiling rail that is provided with a pair of rail parts on both sides of a continuous downward opening and is connected at right angles, and a ceiling rail that is movably disposed within the ceiling rail and that is inserted into the downward opening. a traveling body that suspends and supports a movable wall via a suspension rod; a pair of first rollers that roll on the second rail portion, and a pair of rollers that are pivoted on the other two sides of the traveling body and roll on the second rail portion when the traveling body runs within the other ceiling rail. A second roller is known.

[Problems to be Solved by the Invention] However, with such a configuration, there is a problem that the traveling roller falls into the downward opening when the traveling body passes through the intersection. If such a drop becomes a large movable wall that partitions the floor of a hotel, for example, it will create a large resistance to travel, making it difficult for the vehicle to escape from the intersection.

Further, in this type of traveling body, the upper end portion of the suspension rod is generally supported in a tiltable manner at the center portion of the traveling body so that bending stress etc. do not act on the suspension rod. The conventional one is left and right 2
Since the moving body travels on the rail portion using wheels, when the movable wall is pressed in the width direction, each traveling body swings vertically with respect to the suspension rod, which is an inconvenience. Therefore, there is a problem in which special supplementary measures must be taken.

The present invention aims to solve the above problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention employs the following means.

That is, the suspension support device for a movable wall for a partition according to the present invention includes a ceiling rail that is provided with a pair of rail parts on both sides of a continuous downward opening, and that are connected at right angles to each other, and A running body that is movably disposed within the rail and suspends and supports the moving wall via a suspension rod inserted into the downward opening, and a portion near both ends of the four sides parallel to the ceiling rail of this running body. an escape groove for preventing running rollers other than the eight running rollers that are each pivoted and the four running rollers provided on the ceiling rail and rolling on the rail portion from coming into contact with the rail portion; and a flat part of the lower surface of the traveling body is provided in an area surrounded by four clearance grooves that intersect in a grid pattern at the intersection of the ceiling rails, and supports each of the traveling bodies by rolling. It is characterized by comprising a non-directional rotation support member that prevents the roller from falling into the relief groove.

Furthermore, more preferably, protrusions are provided on the lower surface of the traveling body and located on both sides of the rotation support member in the horizontal turning direction at the intersection.

[Function] With this configuration, when the running roller is located at an intersection, the flat part of the lower surface is supported by the rotating support member, so that the running roller does not fit into the escape groove or the relief groove provided on the ceiling rail. It will not fall into the downward opening. Furthermore, when the traveling body is within the ceiling rail other than the intersection, the traveling body always faces in the direction of travel, and the traveling rollers disposed near both ends of the left and right sides are respectively positioned on the rail portion. Since it rolls and travels on four wheels, the load of the moving wall is distributed and supported, and stable travel is possible without the inconvenience of vertical swinging motion. At this time, the running rollers that are disposed near both ends of the front and rear sides in the direction of travel and have inappropriate rotational direction will be floating on the relief groove, so they will not interfere with the running. do not have.
In this way, this running body can suitably run on any rail section of the orthogonal ceiling rails, even though it has two types of running rollers with different rotational directions. . Moreover, in the present invention, since the rotating shaft support member is disposed in an area surrounded by relief grooves that intersect in a grid pattern at intersections, the running roller is placed very close to the corner of the running body. Even if the rotating support member is arranged to improve running stability, the lower surface of the running body can be easily supported by the rotation support member. In other words, conventionally, when supporting the lower surface of a traveling body with a rotating support member,
As shown in Publication No. 9958, the rotation support member relatively moves between a running roller rolling on a rail section and a running roller orthogonal to the running roller that is not in rolling contact with the rail section. I'm trying to make it passable. However, if this idea is applied to a device with eight running rollers,
The rotation support member is disposed outside each relief groove. However, if the rotation support member is provided in such a position, it becomes difficult to bring each running roller close to the end of each side, and the distance between the two running rolls attached to each side becomes short. Become. As a result, the purpose of using eight wheels to stabilize the vehicle is diminished. There is also a method of making the rotation support member smaller and moving each traveling roller closer to the end, but if the rotation support member is made smaller, it becomes difficult to secure a sufficient distance between the rail surface and the travel body. If the joints of the ceiling rail are not made with high precision, there is a high risk that the lower surface of the traveling body will come into sliding contact with the rail. In contrast, in the present invention, since the rotation support member is disposed inside each relief groove as described above, the running roller rolling on the rail part and the running roller perpendicular to the running roller Therefore, there is no need to reduce the size of the rotation support member to accommodate the small space formed between the rail portion and the traveling roller that is not in rolling contact with the rail portion. Therefore, it is possible to stabilize the running by arranging running rollers near both ends of the four sides, and to support the running body using a relatively large rotating support member to prevent the running body from sliding into contact with the rail surface. can.

Furthermore, in addition to the above-mentioned effect, according to the second invention, when the traveling body attempts to horizontally turn at the intersection of the ceiling rails, the protrusion protruding from the lower surface of the traveling body hits the rotation support member provided on the ceiling rail. They will come into contact and be locked. Therefore, it is possible to prevent the traveling body from turning and being unable to proceed inside any of the ceiling rails.

Furthermore, the protrusion and the rotation support member come into contact only when the traveling body is about to turn, and a required clearance is secured between them to the extent that the traveling body can advance into each ceiling rail. You can keep it. Therefore, the protrusion and the rotation support member are not required to have particularly high precision in their arrangement positions.

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

Embodiment 1 (FIGS. 1 to 3) As shown in FIGS. 1 and 2, a suspension support device for a moving partition wall according to the first invention has continuous downward openings 1a, Ceiling rails 1 and 2 are provided with a pair of rail parts 12 and 22 on both sides of the ceiling rails 1 and 2 and are connected at right angles, and the downward opening is disposed so as to be movable within the ceiling rails 1 and 2. 1

A traveling body 5 that suspends and supports a movable wall 4 of about m length, eight traveling rollers 6 and 7 that are each pivoted near both ends of four sides parallel to the ceiling rails 1 and 2 of this traveling body 5, To prevent running rollers 7 or 6 other than the four running rollers 6 or 7 provided on the ceiling rails 1 and 2 and rolling on the rail portions 12 or 22 from contacting the rail portions 12 or 22. The running rollers 6, 7 are provided at the intersection of the escape grooves 13, 23 and the ceiling rails 1, 2, and support the lower surface flat portion 54 of the traveling body 5 by rotation, so that the respective running rollers 6, 7 fit into the escape grooves 13, 23. It also includes a non-directional rotational support member 83 that prevents it from falling.

The ceiling rails 1 and 2 are buried in the ceiling of the building, and have continuous downward openings 1a and 2a in the center.
The bottom walls 11, 21 having the above-mentioned shapes are 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, 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. It is set up. The connection support member 8 is formed into an L-shape, and its both ends are connected and fixed to the ceiling rails 1 and 2, respectively, and the upper surface of each connection support member 8 is provided with first and second rail portions 12 and 22. is formed, and a criss-crossing portion between the downward opening 1a of one ceiling rail 1 and the downward opening 2a of the other ceiling rail 2 is formed between the central bent portion 8c.

The traveling body 5 includes a disk-shaped main body 5a having a substantially rectangular outer shape in a plan view, and the upper end of a suspension rod 3 is tiltably connected to the center of the main body 5a. First running rollers 6 are provided near both ends of the two sides parallel to the ceiling rail 1 of this running body 5, and second running rollers 6 are provided near both ends of the two sides parallel to the ceiling rail 2. The rollers 7 are each pivoted. Rotating rollers 51 are pivoted to the four corners of this traveling body 5 so as to be horizontally rotatable. That is, at the four corners of the block 5a, the rotating rollers 51 are pivotally attached to the upper surface of the catch seat 52, and the rotating rollers 51 have their outer peripheries projecting outward beyond the outermost edge 5b of the block 5a. side walls 14 of the ceiling rails 1 and 2;
It is designed so that it can be brought into contact with the inner surface of 24. Note that two traveling bodies 5 are provided for each moving wall 4.

A step relief groove 13 is provided near the first rail portion 12 at a portion substantially corresponding to the passage area of the second roller 7, and the running body 5 runs within the ceiling rail. At this time, the first running roller 6 rolls on the first rail portion 12 with the second running roller 7 floating. Furthermore, a step relief groove 23 is provided near the second rail portion 22 at a portion substantially corresponding to the passage area of the first running roller 6, so that the running body 5 runs inside the ceiling rail 2. At this time, the second running roller 7 rolls on the second rail portion 22 with the first running roller 6 floating.

Further, at the intersection of the ceiling rails 1 and 2, more specifically, near the four corners of the rectangular area in plan view surrounded by the four escape grooves 13 and 23, non-directional rotation support members, for example, A support ball 83 is provided. 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 the flat portions 54 on the lower surface of the traveling body 5 located at this intersection are connected to these support balls 8.
3, it is possible to provide rotational contact support. 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.

Note that FIGS. 2 a to 2 d show over time how the traveling body travels on the first rail portion and enters the intersection, and the first traveling roller 6 on the front side in the traveling direction of the traveling body 5 moves forward. The lower flat portion 54 of the traveling body 5 can be supported by rolling contact with the support ball 83 before it reaches the first relief groove 23 lying therein. That is, the horizontal separation distance A between the rolling contact position of the first running roller 6 on the front side in the traveling direction on the rail part 12 and the outermost edge 5b of the running body 5 is equal to the front edge of the relief groove 23 that first meets the outermost edge 5b of the running body 5. The dimension value is set to be larger than the horizontal separation distance B between the support ball 83 and the upper end of the support ball 83 on the side closer to the escape groove 23. The dimensions of each part are set so that a relationship similar to this is established no matter which direction the traveling body 5 travels.

With the above configuration, the traveling body 5 is supported by the support ball 83 in rolling contact with the support ball 83, and the traveling body 5 is
After passing through the states of ~c, the intersection n is reached as shown in d in the figure.
The rollers 6 and 7 can be moved up to the relief grooves 13 and 23 and the downward opening 1
It does not fall into a or 2a. Furthermore, when the traveling body 5 is located within the ceiling rail 1 other than the intersection, the four traveling rollers 6 roll onto the rail portion 12, and the traveling body 5 is located within the ceiling rail 1 other than the intersection. When the moving wall 4 is in the inner position, the four running rollers 7 roll onto the rail portion 22, so the load of the moving wall 4 is distributed and supported by the four rollers 6 and 7. Stable running is possible without the inconvenience of the running body 5 swinging in the vertical direction.
Note that in these cases, since the running rollers 7 and 6 are prevented from coming into contact with the rail parts 12 and 22, respectively, by the relief grooves 13 and 22, the movement of the running body 5 is prevented. Never. Moreover, this one has support ball 83
are arranged inside each relief groove 13, 23 as described above, so that the running roller 6 (7) rolling on the rail portion 12 (22) and the running roller 6
There is no need to reduce the size of the support ball 83 to correspond to the small space formed between the roller 7 (7) and the running roller 7 (6) which is perpendicular to the roller 7 (7) and is moving in a floating state on the escape groove 13 (23). Therefore, the running rollers 6 and 7 are disposed very close to both ends of the four sides to stabilize the running, and the running body 5 is supported by a relatively large support ball 83, and the lower surface of the running body 5 and the rail surface 12 are supported. , 22 can be secured relatively large. Therefore, the traveling body 5 can be prevented from unduly sliding against the rail surfaces 12, 22 without requiring high precision at the joints between the ceiling rails 1, 2, etc.

Embodiment 2 (FIGS. 4 to 6) Next, a suspension support device for a movable partition wall according to a second invention has the structure of the embodiment according to the first invention described above, Projections 55 are further provided on the lower surface of the body 5 and located on both sides of the rotation support member 83 in the horizontal rotation direction at the intersection n.

Specifically, as shown in FIGS. 4 to 6, a predetermined portion on the lower surface of the main body 5a of the traveling body 5,
Four protrusions 55 are integrally provided to prevent horizontal turning of the traveling body 5 at the intersection n. That is, each protrusion 55 is an elongated wall formed at the center of the lower surface of the block 5a, and is located near the outside of the locus of movement of the support ball 83 relative to the traveling body 5. Both end portions 55a of these protrusions 55 are provided on the lower surface of the block 5a at positions located on both sides of the support ball 83 at the intersection n in the horizontal rotation direction (see arrow X in the figure).

If it is equipped with such means,
In addition to the effects associated with the first invention described above, horizontal turning of the traveling body 5 at the intersection n can be effectively prevented. That is, when the traveling body 5 tries to horizontally turn at the intersection n of the ceiling rails 1 and 2, both ends 55a of the protrusion 55 protruding from the lower surface 5a of the traveling body 5 are held by the ceiling rails 1 and 2. It comes into contact with the support ball 83 and is locked. Therefore, it is possible to prevent the problem that the traveling body 5 turns and becomes unable to proceed inside either of the ceiling rails 1 and 2.

Moreover, both ends 55a of the projection 55 and the support ball 83 come into contact only when the traveling body 5 is about to turn, and during that time, the traveling body 5
A required clearance can be secured to the extent that the rails can advance into each of the ceiling rails 1 and 2. Therefore, smooth running of the traveling body 5 can be ensured without requiring high accuracy in the arrangement positions of the protrusion 55 and the support balls 83.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and may deviate from the spirit of the present invention, including the relief groove provided in the ceiling rail and the cross-sectional shape of the protrusion protruding from the lower surface of the traveling body. Various modifications are possible within the range that does not occur.

[Effects of the Invention] Since the present invention has the above configuration, even though the direction can be changed at right angles, the load acting on the traveling body through the suspension rod can be distributed to the four traveling rollers. It is possible to support a heavy movable wall without difficulty. This eliminates the inconvenience of the vehicle falling into the downward opening when passing through an intersection, and it is possible to reliably prevent the vehicle from swinging in the vertical direction.
Therefore, it is possible to provide a suspension support device for a partitioning movable wall that can stably and smoothly support even a large-sized movable wall. In particular, the present invention
Since the rotation support member is arranged inside each relief groove as described above, the running rollers can be arranged near both ends of the four sides to stabilize the running, and also allow relatively large rotations. It becomes easy to support the traveling body by the supporting member and to secure a sufficient distance between the lower surface of the traveling body and the rail surface. Therefore, it is possible to prevent the traveling body from unduly sliding against the rail surface without requiring high precision at the joints of the ceiling rail. According to the second invention, in addition to these effects, the problem of the traveling body turning horizontally at the intersection of the ceiling rails and making it impossible to proceed properly can be solved by requiring high assembly accuracy. This can be easily resolved without any problems.
