Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] 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, so that it 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.

Therefore, as a suspension support device in such a case, for example, as shown in FIGS. 5 and 6, a pair of first
one ceiling rail c comprising a rail portion b;
A continuous downward opening d perpendicular to the downward opening a, and a pair of second openings on both sides of the downward opening d.
the other ceiling rail f comprising a rail portion e;
A running body i that is movably disposed within the ceiling rails c and f and suspends and supports a movable wall h via suspension rods g that are inserted into the downward openings a and d; It is known to have running rollers k rotatably supported at the four corners of the lower surface via vertical shafts j. In this type of device, the running roller k is held horizontally, and each of the rails b and e is tilted so that the outer edge side is higher than the inner edge side. The outer edge of the lower surface of the roller k is brought into contact with the first and second rail parts b and e.

[Problems to be Solved by the Invention] However, in such a structure, at the intersection of the ceiling rails c and f, each first rail part b provided on one ceiling rail c and the other ceiling Each of the second rail parts e provided on the rail f is joined to form a ridge line m that is convex upward. When the traveling body i reaches the intersection of the ceiling rails c and f, the traveling body i
All the running rollers k disposed at the four corners of the ridge line m come into contact with the ridge line m, resulting in an unstable state. Therefore, when a downward load is applied to the traveling body i via the suspension rod g, there is a very high possibility that the traveling roller k falls to a position away from the ridge line m, and a large horizontal turning force is applied to the traveling body i. acts. Therefore, with such a configuration, it is impossible to put it into practical use unless some kind of anti-swing mechanism is provided at the intersection of the ceiling rails c and f to reliably prevent the traveling body i from horizontally turning. be. This is because if the traveling body i makes a horizontal turn at the intersection, it will not be able to proceed inside either of the ceiling rails c and f.

The present invention aims to reliably solve such 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; It is equipped with a running body that suspends and supports a movable wall via a suspension rod inserted through a vertical opening, and running rollers that are rotatably supported via vertical shafts at the four corners of the lower surface of this running body. The first and second rail parts are inclined so that the outer edge side thereof is lower than the inner edge side, and each of the vertical shafts is moved in a diagonal direction so that the lower surface side of each traveling roller approaches the suspension rod. The outer circumferential edge of each traveling roller is made to be inclined so that the outer peripheral edge of each traveling roller rolls into contact with the first and second rail parts.

[Function] According to such a configuration, the joint portion between the first rail portion of one ceiling rail and the second rail portion of the other ceiling rail forms a valley line rather than a ridge line. Therefore, the traveling rollers attached to the four corners of the traveling body that have reached the intersection are held so as to converge at the joining portions of the first and second rail portions, which are joined together forming valley lines. In other words, even if a downward load is applied to a traveling body located at an intersection, that load will act as a force to stably hold the traveling body at the intersection, and a horizontal turning force will be applied to the traveling body. There is no.

Moreover, since each of the running rollers attached to the running body via a vertical shaft is inclined so that its lower surface approaches the suspension rod, the first and second rail portions can be moved as described above. Even if the rollers are inclined so that the outer edge side is lower than the inner edge side, the outer circumferential edges of the respective running rollers can be brought into rolling contact with the first and second rail portions. Since the inclination of each of these rollers is set in the direction along the diagonal line of the roller block, each of the traveling rollers is It is now possible to drive under exactly the same conditions.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4.

As shown in FIG. 1, this suspension support device for a movable partition wall includes one ceiling rail 1 having a continuous downward opening 1a, and a downward opening perpendicular to the downward opening 1a. The movable wall 4 is suspended via the other ceiling rail 2 having a section 2a and a suspension rod 3 which is movably disposed within the ceiling rails 1 and 2 and inserted through the downward openings 1a and 2a. Running body 5 to be suspended and supported
The running body 5 is provided with running rollers 7 which are rotatably attached to the four corners of the lower surface of the running body 5 via a vertical shaft 6.

The ceiling rails 1 and 2 are embedded in the ceiling of a building and have continuous downward openings 1a and 2a in the center. And on one ceiling rail 1,
First rail portions 11, which also serve as the bottom wall, are integrally provided on both sides of the downward opening 1a.
Further, inside the other ceiling rail 2, second rail portions 21 which also serve as the bottom wall are integrally provided so as to be located on both sides of the downward opening portion 2a. Note that the first rail portion 11 and the second rail portion 21 have outer edges 11a, 21a side facing inner edges 11b, 21a, respectively.
It is slightly inclined so that it is lower than the b side.
The one ceiling rail 1 and the other ceiling rail 2 are joined to each other by crossing at right angles. Specifically, the ceiling wall 12, side wall 13, and first rail section 11 of one ceiling rail 1, and the ceiling wall 22, side wall 23, and second rail section 2 of the other ceiling rail 2.
1 are joined to each other.

As shown in FIGS. 2 to 4, the traveling body 5 is a plate-shaped body whose outer shape is approximately rectangular in plan view, and the upper end of the suspension rod 3 is tiltably connected to the center of the traveling body 5. . The vertical shaft 6 is attached to the four corners of this running body 5.
are fixed to each other, and the respective running rollers 7 are rotatably supported at the lower ends of these vertical shafts 6. Each of these vertical shafts 6 is inclined inward along the diagonal line p of the running body 5, and each running roller 7 is inclined in a direction in which the lower surface 7a side thereof approaches the suspension rod 3. The outer peripheral edge 7b of the lower surface of each of these traveling body rollers 7 is configured to roll onto the first rail portion 11 or the second rail portion 21.

With such a configuration, the joint part between the first rail part 11 of one ceiling rail 1 and the second rail part 21 of the other ceiling rail 2 forms a valley line 8 instead of a ridge line. Become. Therefore, the running rollers 7 attached to the four corners of the running body 5 that have reached the intersection converge at the joint portion of the first and second rail parts 11 and 12, which are joined to form the valley line 8. will be retained. That is,
Even if a downward load based on the weight of the moving wall 4 acts on the traveling body 5 located at an intersection, this load acts as a force to stably hold the traveling body 5 at the intersection, and the traveling body 5 5, no horizontal turning force acts on it. Therefore, it is possible to reliably prevent horizontal turning of the traveling body 5 at the intersection without providing a special turning prevention mechanism, and the structure can be simplified.

Moreover, each of the running rollers 7 attached to the running body 5 via the vertical shaft 6 has its lower surface 7a connected to the suspension rod 3.
Because it is inclined so as to approach the first,
Even if the second rail portions 11 and 21 are inclined as described above, it is possible to bring the outer peripheral edges of the respective running rollers 7 into point contact with the first and second rail portions 11 and 21, respectively. can. Since the inclination of each of the running rollers 7 is set in the direction along the diagonal line p of the running roller 7, when each of the running rollers 7 rolls on the first rail section 11,
Even when rolling on the second rail portion 21, it is possible to run under exactly the same conditions. Therefore, there is no need to pay attention to the direction of the traveling body 5 during assembly. Since each running roller 7 and the first and second rail parts 11 and 21 are in point contact as described above, even if each of these running rollers 7 is slightly inclined, there is no problem in running. There is nothing.

Further, the first and second rail portions 11 and 21 are
If it is tilted as described above, the downward opening 1
The first and second rail portions 11, in which a and 2a are raised,
21 between the inner edges 11b and 21b. Therefore, the traveling roller 7
It is possible to minimize the falling motion when crossing a, 2a, and the traveling body 5 can run smoothly.

Incidentally, the inclination angles of the first and second rail parts are not limited to those of the illustrated embodiment, and may be made as close to horizontal as possible, or may be made to incline at an even larger angle.

[Effects of the Invention] Since the present invention has the above-described configuration, it is possible to easily and reliably prevent a traveling body from horizontally turning at an intersection without adding any special turning prevention mechanism. The present invention provides a suspension support device for a movable wall for a partition, which allows a traveling body to run smoothly and a movable wall to move smoothly to a desired route.
