Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a movable partitioning device used for partitioning floors of hotels, offices, etc. as necessary.

[Prior art] This type of movable partition device has a ceiling rail with a continuous opening in the bottom wall fixed to the ceiling of a building, and allows multiple running bodies to run within the ceiling rail. In addition to arranging
A suspension rod is attached to the intermediate portion of each of these traveling bodies, and the lower ends of the suspension rods are passed through the opening and suspended below the ceiling rail. The movable wall is suspended and supported by the pair of suspension rods, respectively, so that the movable wall can be moved along the ceiling rail.

[Problems to be Solved by the Invention] However, conventional movable walls do not have self-propelling power and are moved by pressure from an operator.

Therefore, not only does the moving work require a great deal of effort, but since the area that presses the moving wall is generally constant, there is a problem in that only that area is likely to get dirty. In addition, in the case of a tall movable wall, since the lower half of the wall must be pressed to move, the movable wall may tilt like a curtain due to the running resistance of the running object, causing the suspension rod to There is also the problem that unreasonable force is likely to be applied.

In order to deal with such problems, it has been considered to apply a driving force to the traveling body using a motor or the like so that the traveling body can be configured to run on a moving wall by itself. However, if a motor is built into the movable wall and the motive power of the motor is used to provide driving force to the traveling body, it becomes necessary to supply electric power to each movable wall from the ceiling rail portion. Therefore, it is necessary to run not only control signal lines but also power lines inside the ceiling rail, which makes the wiring complicated and
There is a problem in that the ceiling rail tends to become larger due to the wiring space.

The present invention aims to solve such problems.

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

It is preferable that the power supply terminal is provided in the section.

If you want the power supply point to be inconspicuous and less likely to get in the way, place the power supply terminal on the bottom of the ceiling rail in the movable wall storage area, and protrude the current collection terminal from the top of the movable wall ( It is better.

It is preferable that the rotary sleeve be provided with a pair of motors for rotationally driving the lower end portions of each of these rotary sleeves.

[Operation] With such a configuration, when the movable wall is moved to a location where the power supply terminal is provided, the current collecting terminal provided on the movable wall comes into direct contact with the power supply terminal. Therefore, if the movable wall is stopped at this position, the battery will be in a state where it can receive power supply from the fixed power source via the current collection terminal and the power supply terminal, and will be charged. If the battery is charged in this manner, the movable wall can be driven by electric power from the battery as needed.

It is configured to be able to interrupt the circuit between the current collecting terminal 92 and the battery 186.

Next, the operation of this embodiment will be explained. First, when both traveling motors 84 of each movable wall 5 are activated by electric power from the battery 186, the rotational power of these traveling motors 84 is transmitted to the rotating sleeve 83 via the reducer 89, the driving gear 88, and the driven gear 87. and each sprocket 82 rotates. These sprockets 82 are attached to the ceiling rail 1. Since the sprocket 82 is meshed with a chain 81 fixedly attached to the sprocket 82, both the traveling bodies 6 move on their own within the ceiling rail 1 due to the rotation of the sprocket 82. This causes the movable wall 5 to move along the ceiling rail 11.

When the movable wall 5 is to pass through the intersection A, both motors 84 are stopped when the two traveling bodies 6 supporting the movable wall 5 are stored in the movable rails 22 of each turntable 2. Turn the turntable 2 by 90 degrees. 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, this rotating arm 31, the movable rail 22 horizontally turns and changes direction by 90''. At this stage, the traveling motor 84 is started again to start traveling the movable wall 5, and move the movable wall 5 to the movable wall storage section. 5A. In this way, when the movable wall 5 is guided to the movable wall storage section 5A, the tips of the current collecting terminals 92 come into close contact with the corresponding power supply terminals 91, and the battery 186 is charged. .

By performing an operation opposite to the above operation, each movable wall 5 can be moved to a desired partitioning position.

When the movable wall 5 has been moved to the desired position, both traveling motors 84 are stopped, and then the sealing motor 168 is stopped.
is activated to press the upper and lower draft closing members 54 and 55 against the ceiling C and floor F. In this embodiment, since the sealing member drive mechanism 160 is held by the floating frame 150, a differential pressing action is performed between the upper end contact member 54 and the lower foot contact member 55. The contact members 54 and 55 are pressed against the ceiling surface C and the floor surface F with equal force.

The operations described above can be automatically performed as appropriate using an ordinary sequencer or microcomputer. For this purpose, each movable wall 5 is equipped with a limit switch for detecting whether or not it has come into contact with an adjacent movable wall 5, and upper and lower foot contact members 54 and 55 are pressed against the ceiling surface C and floor surface F. A limit switch is provided to detect whether or not the Further, the turntable 2 is provided with a sensor that detects whether the traveling body 6 of the movable wall 5 has entered a predetermined position of the movable rail 22, a limit switch that detects the turning position of the movable rail 22, etc. put. Furthermore, near the turntable of ceiling rails 11.1□ and 13,
A sensor is provided to detect whether the traveling body 6 has escaped from the turntable 2 and has traveled a certain distance.

In the embodiment described above, the battery is charged in the movable wall storage section, but it is also possible to charge the battery with each movable wall placed at the desired partition position. It is.

Further, the power supply terminal is not limited to being provided on the ceiling rail on one side of the movable wall storage section, but may be provided on the ceiling rails on both sides.

[Effects of the Invention] Since the present invention has the above configuration, the movable wall can be made to travel by itself along the ceiling rail.

Therefore, the labor required to move the movable wall by pressing it is not required, and it is also possible to eliminate the problem that certain parts are easily soiled with dirt from hands or the like. In addition, since there is no need to apply a moving force to the lower half of the moving wall to move the traveling body, there is no need to cause the moving wall to swing like a curtain, and unreasonable bending stress is applied to the suspension rod. This can be effectively prevented.

Moreover, in this model, the motor that provides driving force to the traveling body is driven by a battery mounted inside each moving wall, so only the signal line for motor control is installed inside the ceiling rail. All you have to do is set it up. As a result, the wiring within the ceiling rail can be simplified, and the ceiling rail can be easily downsized.

In addition, if the batteries installed inside each moving wall are charged in the moving wall storage section, the power supply equipment can be consolidated in one place, and the efficiency can be increased even when the moving wall is stopped. The battery can be charged easily. and,
A power supply terminal for charging is provided on the bottom side of the ceiling rail in the movable wall storage section, and a current collection terminal that comes into close contact with this power supply terminal is protruded from the top end of each movable wall. The power supply terminal does not interfere with the original use of the movable wall, and the battery can be reliably charged while simplifying the structure.

If the movable wall traveling drive mechanism is configured as described above, there is no need to mount a motor on the traveling body.

Therefore, the traveling body disposed within the narrow ceiling rail can exert a strong driving force, and the movable wall can reliably move on its own.
