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, respectively, 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 constructed so that they can pass through where the ceiling rails are joined at right angles.

However, as a suspension support device in this case,
a trunk ceiling rail comprising a continuous downward opening and a pair of first rail parts on both sides thereof; and a continuous downward opening perpendicular to the downward opening; Movement via two parallel branch ceiling rails each having a pair of second rail sections on both sides, and a suspension rod that is movably disposed within the ceiling rail and inserted into the downward opening. A running body that suspends and supports portions near both ends of the wall, and one of the running bodies is pivoted to two opposing sides, and when the running body runs within the main ceiling rail, it rolls on the first rail portion. a pair of first rollers that are pivoted on the other two opposing sides of the traveling body and roll on the second rail portion when the traveling body runs within the branch ceiling rail. A device is known which is equipped with the following and is capable of separately guiding two traveling bodies supporting each moving wall into both the branch ceiling rails.

[Problems to be Solved by the Invention] However, with this configuration, there is a problem in that when guiding the movable wall from the main ceiling rail to the branch ceiling rail, the following serious problems occur.

In other words, when guiding a movable wall from a main ceiling rail to a branch ceiling rail, move the movable wall in the width direction, position the traveling body once at the intersection of both rails, and then guide the movable wall from this state to the thickness. It is necessary to simultaneously guide both traveling bodies into their respective branch ceiling rails by moving them in this direction. However, when the traveling body comes to an intersection, the first and second rollers fall simultaneously into the downward openings of the branch ceiling rail and the main ceiling rail, respectively. Therefore, in order to advance the traveling body into the branch ceiling rail,
The second roller must ride onto the second rail section. However, in the past, this run-on often did not go well and the traveling object became stuck, and in such cases, only the tilting of the moving wall took precedence, impeding smooth movement. is likely to occur. Moreover, such problems become particularly noticeable when dealing with large moving walls. In other words, recently, movable walls of this type have been developed that are much taller than a human being, and in order to move such a movable wall, the lower half of the wall must be pressed. I have no choice but to. When moving the movable wall in the width direction along the main ceiling rail, the pair of traveling bodies will be positioned at intervals in the direction of movement.
Unless the weight of the moving wall is extremely small, the moving wall will not tilt even if there is some resistance to the movement of the moving object, and the pressing force will effectively act as a force to move the moving object forward. . However, when the movable wall is moved in the thickness direction along the branched ceiling rail as described above, both traveling bodies face in the direction of travel and are in a side-by-side state. For this reason,
If the traveling body gets caught when pressing the lower half of the moving wall, the pressing operation force will not act effectively as a force to move the traveling body forward, but instead the moving body will be used as a fulcrum to move the moving body. This acts exclusively as a force that tilts the material in the thickness direction. However,
In such a case, it is no longer possible to guide the moving wall into the branch ceiling rail.

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 partition wall according to the present invention includes a trunk ceiling rail comprising a pair of first rail parts on both sides of a continuous downward opening;
a parallel branch ceiling rail having a continuous downward opening perpendicular to the downward opening and having a pair of second rail parts on both sides of the downward opening; and a parallel branch ceiling rail running within the ceiling rail. a traveling body that suspends and supports the movable wall through suspension rods that are arranged so that the movable wall can be suspended through suspension rods that are inserted into the downward opening; A pair of first rollers that roll on the first rail part when traveling within the ceiling rail, and a pair of first rollers that are pivoted to two opposing sides of the other of the traveling body, so that the traveling body runs within the branched ceiling rail. A pair of second rails rolling on the second rail portion
two rollers supporting each moving wall;
A suspension support device for a moving partition wall, which is capable of guiding a traveling body of a platform separately into both branch ceiling rails, the suspension support device being able to guide a traveling body of a platform separately into both the branch ceiling rails, the suspension support device being capable of guiding a traveling body of a platform separately into both the branch ceiling rails, A pair of non-directional rotational support members is disposed so that the lower flat part of the traveling body located at the intersection can be rotatably supported by the rotational support members, and the main ceiling rail and at least A first rail part on the side opposite to the branch passageway at the intersection with one of the branch ceiling rails has a concave part for avoiding contact with the first roller of the traveling body at the intersection, and a recess for avoiding contact with the first roller of the traveling body at the intersection, and a recess for avoiding contact with the first roller of the traveling body at the intersection, and The present invention is characterized in that an inclined portion is provided for once lifting the first roller and guiding it to the recessed portion.

[Function] With such a configuration, the traveling body entering the intersection is supported by the rotational support members disposed at the four corners with its lower flat portion in contact with the first and second rotation support members.
It is possible to reliably prevent the roller from falling to a lower position than when traveling. Therefore, it becomes possible to move the traveling body smoothly in any direction of the ceiling rail.

It should be noted that with only a rotary support member provided, it is very difficult to accurately position the traveling body at the intersection when guiding the traveling body to the branch ceiling rail. A recessed portion is provided in the first rail portion on the opposite side of the branch passage at the intersection with at least one of the branch ceiling rails to prevent the first roller of the traveling body located at the intersection from coming into contact with the first rail portion. The first roller rolling thereon is once lifted by the inclined part and guided to the recessed part. Therefore, when the first roller is guided into this recess, the traveling body sinks to its original traveling height due to gravity, and it becomes clear that the traveling body is located at an intersection. It will be stably maintained in that position.

Moreover, since the first roller does not fall directly into the groove, etc., but is lifted up and then returns to its original position, braking due to weight is applied to the traveling body before the intersection. become. Therefore, it becomes possible to smoothly stop the traveling body at an intersection.

When the traveling body is located at an intersection, the first roller is moved to the first roller due to the presence of the recess.
Since the traveling body does not come into strong contact with the rail part, this, together with the fact that the traveling body is supported by the rotation support member, prevents the traveling body from coming into contact with the rail when it advances from the intersection into the branch ceiling rail, or from inside the branch ceiling rail. When returning to the intersection, there is no longer any chance of getting stuck or experiencing large sliding resistance.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 6.

There is. The connection support member 18 is an L-shaped metal fitting, and one end side 18a is fixed between the first rail part 12 of the main ceiling rail 1 and the bottom wall 11 using a bolt 81 and a plate nut 82. , the other end side 18b is the bolt 81
It is fixed between the second rail part 22 of the branch ceiling rail 2 and the bottom wall 21 using a plate-like nut 82 and a plate nut 82 . The upper surface of both connection support members 18 is set flush with the upper surfaces of the first and second rail parts 12 and 22, and between the central bent part 18c, the downward opening 1a of the main ceiling rail 1 and the branch ceiling A T-shaped intersection with the downward opening 2a of the rail 2 is formed. Further, the first rail portion 12 on the side opposite to the branch passage of this T-shaped intersection has a flat portion 8c set at a height level flush with the first rail portion 12, and above the flat portion 8c. A guide member 8 integrally formed with a recessed portion 8f and an inclined portion 8d is disposed. The guide member 8 is attached to the trunk ceiling rail 1 by fixing its both ends 8a using bolts 81 and nuts 82, similarly to the connection support member 18 described above. The recessed portion 8f and the inclined portion 8d will be described later.

In addition, main ceiling rail 1 and branch ceiling rail 2

The top walls 13 and 23 of No. 2 are cut out, and the T-shaped top plate 9 is arranged flush with the top walls 13 and 23. This top plate 9 is made of a channel material, for example, to form the side walls 14, 24 of the ceiling rails 1, 2.
Fixed.

The traveling body 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 traveling body 5, and a second roller 7 is rotatably mounted on the other two opposing sides. Note that two traveling bodies 5 are provided for each moving wall 4. When the traveling body 5 travels within the main ceiling rail 1, the first roller 6 rolls on the first rail portion 12 with the second roller 7 floating within the downward opening 1a. When traveling on branch ceiling rail 2,
The second roller 7 rolls on the second rail portion 22 with the first roller 6 floating in the downward opening 2a.

As shown in FIG. 3, rotating rollers 51 are pivoted to the four corners of the traveling body 5 so as to be horizontally rotatable. That is, catch seats 52 are integrally formed at the four corners of the traveling body 5, and these seats 52
The rotating roller 51 is attached to the upper surface of the roller using a shaft 53. The rotating roller 51 has a running body 5 on its outer periphery.
It is made to protrude outward from the outermost surface of the ceiling rails 1 and 2, and is adapted to come into rolling contact with the inner surfaces of the side walls 14 and 24 of the ceiling rails 1 and 2.

Also, the four corners of the intersection of the ceiling rails 1 and 2, specifically, the four corners of a rectangular area in plan view surrounded by the parallel running track of the first roller 6 and the parallel running track of the second roller 7. A non-directional rotary support member, for example, a support ball 83 is provided at the support ball 83 . Specifically, the upper surface portions of the central bent portions 18c of each of the connection support members 18 and the flat portions 8c of the guide member 8 are
Support balls 83 are rotatably held at positions corresponding to c. The upper end portion of the support ball 83 projects upwardly from the upper surface of each of the connecting support member 18 and the guide member 8, and the flat portion 54 on the lower surface 5a of the traveling body 5 located at this intersection is connected to the support ball 83. 83 to enable rolling contact support. That is, the traveling body 5 at this intersection is held by these support balls 83 at approximately the same height position as when traveling within the ceiling rails 1 and 2.

Four protrusions 55 are integrally provided at predetermined positions on the lower surface 5a of the traveling body 5 to prevent horizontal turning of the traveling body 5 at the intersection n. Specifically, as shown in FIGS. 3 to 5,
Each protrusion 55 is an elongated wall-shaped member formed on the edge of the lower surface 5a of the traveling body 5 adjacent to each of the first and second rollers 6, 7, and is formed in the shape of a slender wall on the lower surface 5a of the traveling body 5. It is located near the outside of the movement trajectory. Both ends 5 of these protrusions 55
5a is the lower surface 5a, which is in the horizontal turning direction with respect to the support ball 83 at the intersection n (arrow X in the figure).
(See) They are located on both sides.

Further, as shown in FIGS. 2 and 6, the height position of the deepest portion of the guide member 8 corresponding to the downward opening 2a of the branch ceiling rail 2 is A recessed portion 8f is provided at a height that is equal to or lower than the height of the first rail portion 12. In order to guide the first roller 6 rolling on the first rail portion 12 to the recess 8f, sloped portions 8d that are inclined toward the recess 8f are provided on both sides of the recess 8f. It is being That is, the first roller 6 of the traveling body 5 that is about to enter the intersection n moves along this inclined portion 8d.
When the vehicle 5 gradually ascends the slope and reaches the intersection n, the guidance of the first roller 6 into the recess 8f is completed at the same time.

With such a configuration, at the intersection of the ceiling rails 1 and 2, the lower surface 5a of the traveling body 5
Since the flat portions 54 are supported by the support balls 83, even when the traveling body 5 reaches the intersection n, the first roller 6 and the second roller 7 are connected to the downward openings of the ceiling rails 2 and 1, respectively. It does not fall into 2a and 1a at the same time. And this support ball 8
3 is non-directional and can roll in all directions, so depending on how much force is applied, the traveling body 5 at the intersection n can be guided in the two directions of the branch ceiling rail or continue to be guided in the main ceiling rail 1. It can also be run.

Then, the traveling body heading toward the intersection is gradually lifted by one wheel of the first roller 6 rolling on the first rail part 12 climbing the slope part 8d, and when the traveling body 5 reaches the intersection n. The first roller 6 is guided into the recess 8f, and the traveling body 5 sinks slightly, and the first roller 6 is guided into the recess 8f.
With the roller 6 floating in the recess 8f, the lower flat portion 54 of the traveling body 5 is supported by the support balls 83 in rolling contact. Moreover, the first roller 6 does not easily ride onto the first rail portion 12 due to the presence of the both side edges 8e of the recessed portion 8f, and is stably held in that position unless a pressing force is applied. be done. Thus, the traveling object 5 is automatically positioned within the intersection n.

Moreover, since the first roller 6 does not fall directly into the groove or the like, but is lifted once and then returns to its original position, the traveling body 5 is braked by its weight before the intersection n. It will be called. Therefore, it becomes possible to smoothly stop the traveling body 5 at the intersection n, and the traveling body 5
It is possible to effectively prevent problems such as an impact being applied when the vehicle 5 is positioned or the traveling body 5 passing through the intersection n due to inertia. Therefore,
In addition to improving the durability of each part,
Operability can be improved.

When the traveling body 5 is located at the intersection n, the first roller 6
However, since the traveling body 5 is no longer strongly abutted against the first rail portion 12, and the traveling body 5 is supported by the support ball 83, the traveling body 5 advances from the intersection n into the branch ceiling rail 2. When returning to the intersection n from inside the branch ceiling rail 2, there is no possibility of getting caught or generating large sliding resistance. Therefore, along with the main ceiling rail 1,
Both running bodies 5 of the moving wall 4 that has been moved in the width direction
Even when the movable walls 4 are pushed into the parallel branch ceiling rails 2 at the same time by pressing the moving walls 4 in the thickness direction, smooth operation can be achieved.

Further, when the traveling body 5 tries to horizontally turn at the intersection n, both ends 55a of the protrusion 55 protruding from the lower surface 5a of the traveling body 5 are connected to the support balls held by the ceiling rails 1 and 2. 83 and is locked. This effectively prevents the running body 5 from horizontally turning.

Note that the recessed portion and the inclined portion may be provided at all intersections between the main ceiling rail and the branch ceiling rail, or may be provided only at the intersection between one of the branch ceiling rails and the main ceiling rail. In that case, it is preferable to provide only a non-directional rotation support member and an extremely shallow recess at the intersection between the other branch ceiling rail and the main ceiling rail.

Further, the cross-sectional shape and setting manner of the inclined portion and the recessed portion can be variously modified without departing from the spirit of the present invention.

[Effects of the Invention] Since the present invention has the above configuration, the traveling body performs a falling operation at the intersection of the main ceiling rail and the branch ceiling rail, and the first roller and the first
It is possible to reliably and rationally prevent problems such as sliding between the rail part and ensure smooth operation of the traveling body within the intersection, as well as to guide the moving wall to the branch ceiling rail. It is possible to provide a suspension support device for a partition movable wall that can easily and reliably position a traveling body at an intersection, which is essential when moving a partition.
