BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a movable partition which opens and closes by driving and driving a panel electrically, and more particularly to a panel which travels at any height regardless of the traveling mode of the panel. hurt a person panel passes
To a technique for trying to avoid to become the.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 62-27338 discloses a movable partition wall which is driven and driven by a motor to open and close the panel.
No. 4 proposes this. And when to open and close in this manner by the panel is electrically driven, travel panels there is a problem that sometimes damage the like accidentally children to <br/> crossing. To solve such a problem, FIG.
As shown in the plan view of FIG. 8, an infrared transmitter a and an infrared receiver b are provided along the rail to stop the driving of the panel 1 when the reception of infrared light is interrupted.

[0003]

However, in the above configuration, the infrared transmitter a and the infrared receiver b
Although the intruder can be detected at the height where is installed, an intruder such as a baby at a position higher or lower than the installation location cannot be detected, and thus an intruder such as a baby is detected as a panel. When the panel 1 branches off to one of the straight rails and is retracted as shown in FIG. 18, the infrared transmitter a and the infrared receiver b are linearly moved. Even if it is arranged, the traveling mode of the panel 1 and the sensor configuration at the storage location cannot detect an intruder , and may hurt the intruder.
There is a problem that it may be turned off .

[0004] The present invention is a which was devised in view of the problems of the prior art, it is an object to be traveling to the panel resulting in damage to press strongly intruder
An object of the present invention is to provide a safety device for a moving partition wall which can be reliably avoided , and which can reliably detect and measure safety even with a small force due to an obstacle.

And decide in advance which direction to run at the 13 branch
The position and height of the branch control wheel 12 accordingly.
Even if the number of branch points increases,
Can be forked.

By the way, at the part where the upper rail 13 branches, the trolley duct 15 also branches.
In this branch portion, the power supply conductor 16 and the signal conductor 1
7 is cut in the trolley duct 15, and the cut power supply conductor 16 and signal conductor 17
Are connected separately from the original cut power supply conductor 16 and signal conductor 17 by sending wiring or the like. In this cut portion, the trolley 18 running in the trolley duct 15 is connected to the power collector 16 and the signal conductor 17 by the current collector 22.
In order to solve this problem, the trolleys 18 are provided on the runners 3 provided at both ends of the panel 1 so that one trolley 18 of the two trolleys 18 is provided for each panel 1. However, even if the power supply conductor 16 and the signal conductor 17 are located at a cut portion in the branch portion, the current collector 22 of the remaining one trolley 18 can contact the power supply conductor 16 and the signal conductor 17 to collect power. This is so that there is no obstacle to current collection at the branch part.

When the switch is turned on and power is supplied to the motor 4 to rotate the motor 4, the rotation of the motor 4 is transmitted to the runner 3 via the electromagnetic clutch 5 to rotate the running wheels of the runner 3. Then, the vehicle runs on the panel 1. In the above configuration, as shown in FIG. 1, the present invention operates the end face on one end side and the end face on the other end side in the traveling direction of the panel 1 with a pressing force of a certain level or more over the entire vertical length thereof. A pressing force sensor S for stopping electric driving is provided .

As described above, by providing the pressing force sensor S for operating the panel 1 at a certain pressing force or more to stop the electric drive of the panel 1 over substantially the entire length of the end surface in the running direction of the panel 1, When the panel 1 hits the intruder and presses the pressing force sensor S on the end face in the traveling direction to a certain level or more during the electric traveling of the vehicle, the electromagnetic clutch 5 of clutch-brake type is immediately disengaged, and the brake is actuated. It stops the running of the vehicle suddenly. As described above, by providing the pressing force sensor S on the end surface of the panel 1 in the traveling direction and stopping the traveling of the panel 1, regardless of how the panel 1 is branched and run, regardless of the traveling mode. This makes it possible to detect an intruder. In addition, since the pressing force sensor S is provided on the end surface of the panel 1 in the running direction substantially over the entire length, even if the intruder is short, such as a baby, it can sufficiently detect the intruder. It does not hurt. The configuration for stopping the traveling of the panel 1 may be any configuration as long as it stops the energization of the traveling wheels 2.
