Description

TECHNICAL FIELD The present invention relates to a moving partitioning device used when partitioning a floor of a hotel, an office, or the like as needed.

[Prior Art] In this type of moving partition device, a ceiling rail having a continuous opening in a bottom wall is fixed to a ceiling of a building, and wheels are diagonally positioned at four corners in the ceiling rail. In addition to arranging a plurality of traveling bodies provided so as to be able to travel, a suspension rod is attached to an intermediate portion of each of these traveling bodies, and the lower end side of these suspension rods is passed through the opening portion to the lower side of the ceiling rail. It is drooping. The movable walls are suspended and supported by the pair of suspension rods, and the movable walls can be moved along the ceiling rail.

[Problems to be Solved by the Invention] However, the conventional moving wall has no self-propelling force and is moved by the pressing force of the operator. Therefore, not only a great amount of labor is required for the moving work, but also the portion that presses the moving wall is almost constant, so that there is a problem that only that portion is easily soiled. Also, on tall moving walls,
Since the lower half part is pressed and moved, the moving wall may tilt like a goodwill due to the running resistance of the running body, and an unreasonable force easily acts on the suspension rod. There is also.

In order to deal with such a problem, it has been considered that a driving force is applied to the traveling body by a motor or the like so that the traveling wall can be self-propelled.

By the way, in such a structure, it is necessary to provide a mechanism for guiding the traveling body to a desired route at a portion where the ceiling rails intersect. Therefore, as a concrete example, a turntable is provided at a portion where the ceiling rails intersect, and when the traveling body reaches the intersection, the turntable is turned to guide the traveling body to a desired route. There is.

However, in such a structure, it is necessary to secure a clearance at the rail joint between the ceiling rail and the turntable to allow the rotary operation of the turntable. Therefore, in order for the traveling body to pass through the rail joint, it is necessary to make the wheels pivotally mounted on the left and right gradually fall into the rail joint, and the rattling at this time causes malfunction or operation on the moving wall. The movement of the center of gravity that occurs when the wheel falls may adversely affect the support state of the moving wall.

The present invention aims to effectively solve such problems.

[Means for Solving the Problems] The present invention adopts the following configurations in order to achieve the above objects.

That is, the moving partition device according to the present invention includes a plurality of ceiling rails, a turntable, a table drive mechanism,
A traveling body, a suspension rod, a moving wall, and a moving wall traveling drive mechanism, wherein the plurality of ceiling rails are
The turntables are arranged horizontally with their ends facing the intersections, and the turntable is arranged at the intersections and provided with a movable rail having a sectional shape equal to that of the ceiling rail at a position deviated from the rotation axis. The table drive mechanism is configured so that the turntable can be horizontally swung to selectively match the end of the movable rail with the end of the ceiling rail, and each moving wall has four corners. A plurality of traveling bodies equipped with wheels and suspension rods suspended from these traveling bodies are respectively suspended and supported on the ceiling rail, and the moving wall traveling drive mechanism makes the moving walls independent of each other. It is characterized in that it is configured to be able to travel.

In order to make the moving wall self-propelled with a simple configuration, the moving wall traveling drive mechanism is fixed to the inner surface of the side wall of the ceiling rail and the movable rail, the chain is engaged with the sprocket, and the upper end is It is preferable that the sprocket is provided with a rotary sleeve fixedly mounted on the outer periphery of the suspension rod so as to be rotatable, and a motor housed in the moving wall and rotationally driving the lower end of the rotary sleeve. .

[Operation] With such a configuration, each moving wall can be independently moved along the ceiling rail by applying a driving force to the traveling body by the function of the moving wall traveling drive mechanism. . When the movable rail is provided at a portion deviated from the axis of the turntable, the rail joint formed when the end of the movable rail is aligned with the end of the ceiling rail is formed in the traveling direction of the traveling body. On the other hand, an eccentric arc curved from right front to left rear (or left front to right rear) is drawn. Therefore, when the traveling body passes through the rail seam, the left and right wheels do not reach the rail seam at the same time, but cross the rail seam temporally before and after the rail seam. This can be said for each of the wheels, and the entire ground contact point of the wheels does not reach the rail joint at the same time but partially crosses the rail joint along the width direction. For this reason,
It is possible to effectively eliminate rattling when the traveling body travels on the rail joint, and as a result, it is possible to ensure smooth operation of the moving wall when passing the intersection.

Next, the operation of this embodiment will be described. First, when the traveling motor 84 is activated, the rotational power of the traveling motor 84 is transmitted to the rotary sleeve 83 via the reduction gear 89, the drive gear 88 and the driven gear 87, and the sprocket 82 rotates. The sprocket 82, the chain which is fixed to the ceiling rail 1 ₁
81 for which it had been engaged in by the rotation of the sprocket 82, so that the traveling body 6 is self ceiling rail 1 _1.
This makes that the moving wall 5 is moved along the ceiling rail 1 _1. When passing the intersection A on the moving wall 5,

Movable rail
Since the chain 81 is fixedly provided in the movable rail 22, the traveling body 5 can be moved to a desired position in the movable rail 22. In this state, the turntable 2 is turned to change the direction of the moving wall 5. Specifically, when the motor 34 of the table drive mechanism 3 is operated to rotate the rotating arm 31 from the starting point a to the ending point b, the movable rail 22 connected to the rotating arm 31 via the link rod 35. Turns horizontally and turns 90 ° (see Fig. 4). As a result, the ends of the movable rail 22 matches the second end portion of the third ceiling rail 1 _2, 1 _3. At this stage, turning of the turntable 2 is finished, and the traveling motor 84 is activated again to start traveling of the moving wall 5. Then, according to this operation, the turntable 2

The close contact members 54, 55 are pressed against the ceiling surface C and the floor surface F with an equal force.

The operation described above can be automatically performed as appropriate using a normal sequencer or microcomputer. Therefore, each moving wall 5 has a limit switch for detecting whether or not the moving wall 5 is in contact with an adjacent moving wall 5,
Limit switches for detecting whether the upper and lower close contact members 54, 55 are pressed against the ceiling surface C and the floor surface F are provided. Further, the turntable 2 is provided with a sensor for detecting whether or not the traveling body 6 of the moving wall 5 has reached a predetermined position of the movable rail 22, a limit switch for detecting the turning position of the movable rail 22, and the like. deep.

In the embodiment described above, the turntable is configured to hold two traveling bodies at the same time.
As shown in FIG. 14, the turntable 202 is provided in a relatively small size, and each time each traveling body 206 reaches the intersection B of both ceiling rails 201 ₁ and 201 ₂ , the turntable 202 is turned to a desired route. It can also be configured to guide. Further, in the above-mentioned embodiment, the case where the turntable is provided at the intersection where the three ceiling rails meet has been described.
As shown in FIG. 14, it is of course possible to use a portion where _two ceiling rails 201 ₁ and 201 ₂ intersect or an intersection where four or more ceiling rails meet as a constituent element.

EFFECTS OF THE INVENTION Since the present invention has the above-described configuration, the moving wall can be self-propelled along the ceiling rail. Therefore, it is possible to eliminate the trouble of pressing the moving wall to move the moving wall, and also to solve the problem that a certain portion is easily soiled due to hand marks or the like. In addition, since it is not necessary to apply a moving force to the lower half of the moving wall to move the traveling body, it does not cause good-moving swing of the moving wall, and an unreasonable bending stress acts on the suspension rod. Can be effectively prevented.

Moreover, since the movable rail and the ceiling rail are made to be adjacent to each other at a portion deviated from the rotation axis center of the turntable, the rail joint formed between both rails forms a curved eccentric arc, and the Effectively prevent the wheels from falling into the clearance of the rail joint at the same time.
Further, also in each wheel, the risk of instantaneously losing the foothold by the rail joint is reduced. For this reason,
It is possible to reliably eliminate the rattling of the traveling body at the time of passing the intersection, and to ensure the smooth operation of the moving wall.

Further, if the moving wall traveling drive mechanism is configured as described above, it is not necessary to mount the motor on the traveling body. Therefore, a strong driving force can be exerted on the traveling body arranged in the narrow ceiling rail, and the moving wall can be surely self-propelled.
