DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving partitioning device used for partitioning a floor of a hotel, office or the like as required.

[0002]

2. Description of the Related Art Conventionally, as this kind of moving partition device,
A guiding ceiling rail having a continuous opening in the bottom wall, a parallel storage ceiling rail having a continuous opening in the bottom wall and arranged substantially orthogonal to the guiding ceiling rail, and A traveling body disposed so as to be able to travel, and a suspension rod suspended downward from the traveling body through the opening.
A moving wall suspended from and supported by a ceiling rail via a pair of traveling bodies and suspension rods, and a moving wall that moves each moving wall in the thickness direction while supporting the paired traveling bodies on each storage ceiling rail. A device including a drive mechanism is known.

[0003]

However, the moving wall driving mechanism in this kind of moving partitioning device holds the running body and the suspension rod by the urging members arranged at a constant pitch and attaches it to the storage ceiling rail. The plurality of supported moving walls are moved in the thickness direction. Therefore, it is difficult to arrange the moving walls close to each other at the storage position, and there is a problem that storage efficiency cannot be improved.
That is, since a turntable or the like is provided at the intersection of the guide ceiling rail and the storage ceiling rail, the leading moving wall is used for guiding unless a certain distance is secured between the moving walls. When sent out under the ceiling rail,
The traveling body of the succeeding moving wall interferes with the turntable or the like, and it becomes impossible to pull out the leading moving wall to the use position along the guide ceiling rail. Therefore,
In such a case, there is a problem that the moving walls cannot be efficiently stored at the storing position by densely overlapping the moving walls.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a structure in which moving walls supported by a storage ceiling rail and superposed in the thickness direction are provided one by one under the guide ceiling rail. When sending out to the moving wall, the moving speed of each moving wall that is sequentially the first moving wall is configured to be faster than the moving speed of the other moving walls, and the separation distance between the first moving wall and the succeeding moving wall is different from the other moving walls. It is designed to be larger than the distance between the moving walls.

The second horizontal portion 49c is positioned higher than the first horizontal portion 49b by a height H.

Next, the operation of the moving partition device will be described. First, when the plurality of moving walls 5 are stored in the storage, the moving walls 5 are arranged in an overlapping manner in the thickness direction so as to approach each other. In order to guide each moving wall 5 to the saloon 17 from this state, first, the moving wall drive mechanism 8 is operated to move the actuator 47 in the direction of the guide ceiling rail 1 by the mounting interval (1 pitch A). . As a result, the biasing arm 48 pivotally attached to the actuator 47 moves in a direction approaching the guide ceiling rail 1, and presses the upright rod 38 of each moving wall 5 with the pressing roller 65 provided at the end thereof. Will be. Therefore, each moving wall 5 is conveyed in the direction of the guide ceiling rail 1 by one pitch A. At that time, the leading moving wall 5
The guide roller 64 of the urging arm 48 that presses the first horizontal portion 49b of the cam body 49 passes through the inclined portion 49d to reach the second horizontal portion 49c.
Is lifted upward by the height H, and the urging arm 48 rotates forward with respect to the actuator 47 in the traveling direction. Therefore, only the leading moving wall 5 is sent forward at a faster speed than the other moving walls 5, moves more than one pitch A described above, and is pushed under the guide ceiling rail 1. Information ceiling rail 1
The two traveling bodies 3 supporting the moving wall 5 extruded below
The transfer from the ceiling rail 2 for storage to the movable rail 43 of the turntables 6 and 7 is performed (see FIG. 3). At this stage, by turning each of the turntables 6 and 7 horizontally by 90 degrees, the direction of both traveling bodies 3 can be changed to a direction along the guide ceiling rail 1. In this state, by pressing the moving wall 5 in the width direction,
The traveling body 3 moves onto the guide ceiling rail 1, and the moving wall 5 can be moved along the guide ceiling rail 1 to be guided to the use position of the saloon 17 (FIG. 4). reference). In order to return the movable wall 5 suspended at the use position to the storage position, basically, the above-described operation may be performed in reverse. No attitude control by 49 is performed. That is, when the upright rod 38 of the moving wall 5 is pressed backward by the pressing roller 65 of the urging arm 48, the stopper 48d of the urging arm 48 is attached to the lower surface of the actuator 47 as shown in FIG. It will rotate and lock to the contact position.

As described above, in the present apparatus, when the moving walls 5 supported by the storage ceiling rail 2 and superposed and arranged in the thickness direction are sent out one by one below the guide ceiling rail 1,
The delivery speed of each moving wall 5 that is sequentially the top is changed to the other moving walls 5.
Since the are set to be faster than the moving speed, as shown in FIG. 7, the pitch between the moving wall 5 ₂ and a subsequent top moving walls 5 ₁ of, other moving wall 5 ₂ to 5 _n together Pitch A
Larger than. Therefore, turn the clearance between the moving wall 5 ₂ and a subsequent top moving wall 5 of _the tables 6,7
While setting a sufficient value with no bearing on the operation or the like, it is possible to increase the storage density to approximate other moving wall 5 ₂ to 5 _n.

In the above-described embodiment, the case where the upright rod is urged by the urging arm has been described. However, the present invention is not necessarily limited to such a case. The traveling body and the suspension rod may be urged by an urging member that performs a fast-forward operation according to.

[0019]

As described above, according to the present invention, the pitch between the leading moving wall and the succeeding moving wall at the time of feeding from the storing ceiling rail to the guiding ceiling rail is determined by changing the pitch of the other moving wall. Because it is possible to make the pitch larger than the pitch between each other, multiple moving walls are densely stacked without causing trouble in operation when moving the moving wall from the storage ceiling rail to the guide ceiling rail. Thus, the moving walls can be efficiently stored in a narrow space.

If the moving wall is pressed by the urging arm and moved, and the posture of the urging arm is controlled by the cam body, the above-described fast-forward operation of the moving wall can be performed.
With a simple configuration, it is possible to perform the operation reliably. In particular, if the biasing arm is shaped like a letter when viewed from the side, and the guide roller provided at the bent portion is guided by a cam body, the cam body can be made into a simple rail shape, It is possible to simplify the structure and the assembly work.
