があった。[Problem to be Solved by the Invention] The conventional safety device for a passenger conveyor is constructed as described above, and a single detector 6 is installed in the center of the curved part 2A of the moving handrail guide 2 or in the straight part 2B. Therefore, if the moving handrail 4 comes off just above the detector 6 as shown in FIG. 7, the passenger conveyor can be stopped, but the moving handrail 4 does If the vehicle were to disengage at a location other than the center, the passenger conveyor could not be stopped immediately, posing a safety problem for passengers. Furthermore, the movable handrail 4 that moves in a curved manner on the curved portion 2A causes wear between the guide rail 3 made of resin or the like, but when wear occurs, the distance between the movable handrail 4 and the detector 6 changes, and the detector There was a possibility that this would lead to the malfunction of 6. Furthermore, when the detector 6 is installed in the straight section 2B,
The moving handrail 4 that came off at the curved part 2A where it is most likely to come off is the detector 6.
It took a long time to get to the opposite position, posing a safety problem for passengers.

A movable handrail guide 2 having an inverted hat-shaped cross section is welded to the movable handrail guide 2, and a guide rail 3 is fitted to the upper projecting portion of the movable handrail guide 2. A movable handrail 4 is slidably fitted therein. The movable handrail 4 guided by the movable handrail guide 2 is made of rubber or the like and has a horizontal C-shape, and inside thereof,
A detected object 5 made of a magnetic material is buried. and,
Reference numeral 6 denotes a plurality of non-contact type detectors installed inside the movable handrail guide 2, and the detector 6 consisting of a nearby switch etc.
When one side of the movable handrail 4 is completely removed from the movable handrail guide 2 and the distance between the movable handrail 4 and the detected object 5 exceeds the reference value, the movable handrail 4 faces the inner upper surface with a gap. It has a function of detecting detachment of the moving handrail 4 and stopping the passenger conveyor in operation. Further, the plurality of detectors 6 are each installed near the boundary between the curved part 2A and the pair of straight parts 2B that sandwich the curved part 2A near the upper floor of the handrail guide 2. In other words, the plurality of detectors 6 are installed near the normal line 7 at both ends of the curved portion 2A.

生するのを未然に防止することができる。According to the above configuration, since the detectors 6 are installed near the boundaries of the pair of straight portions 2B with the curved portion 2A sandwiching the curved portion 2A, the movable handrail 4 is located at a position other than the center of the curved portion 2A. (See FIG. 2) Even if the passenger conveyor is pulled out, the passenger conveyor can be stopped immediately, and safety can be improved. In addition, the wear of the guide rail 3 near the normal line 7 at both ends of the curved portion 2A is small, and the distance between the moving handrail 4 and the detector 6 does not change, so it is possible to prevent the detector 6 from malfunctioning. Then, the moving handrail 4 that came off at the curved portion 2A moves to a position opposite the detector 6 in a short time, so the detector 6
This can be expected to speed up detection, and it is possible to prevent accidents involving passengers' hands or the like from being caught between the movable handrail guide 2 and the partially disengaged movable handrail 4.

る。As described above, according to the present invention, since the detectors are installed near the boundaries between the curved part of the pair of straight parts that sandwich the curved part of the handrail guide, Even if the passenger conveyor is pulled out at a location other than the center of the section, the passenger conveyor can be stopped immediately, which has the effect of improving safety. In addition, the wear of the guide rail near the normal line at both ends of the curved portion is small, and the distance between the moving handrail and the detector does not change, making it possible to prevent malfunction of the detector. Since the moving handrail that has come off at the curved part will move to the position opposite the detector in a short time, it is expected that the detector will be able to detect it more quickly. This has the effect of preventing personal accidents from occurring due to hands being caught.
