- a step chain 21 that is also engaged with the step 17 is hung on a step drive sprocket 30 fixed to the drive shaft 29 on the upper side of the staircase and a step sprocket 36 that is rotatably fixed on the lower side of the step.
- the step 17 it is transmitted to the step 17 by the driving force from the driving machine 18, and the step 17 can be moved. Further, the driving force can be transmitted between the handrail drive sprocket 31 and the moving handrail drive device 22 via the handrail chain 23, and the moving handrail drive device 22 applies the transmission force to the handrail guide rail 24. The driving force is transmitted to the moving handrail 9 and moves in synchronization with the step 17.
- FIG. 15 is a detailed view of the moving handrail drive device 22 shown in FIG.
- the handrail chain 23 hung on the handrail drive sprocket 31 is also hung on the handrail sprocket 32 fixed to the movable handrail drive device 22 so as to be freely rotatable.
- the gear drive chain 26 is hung on a handrail sprocket 25 fixed coaxially with the handrail sprocket 32, a handrail sprocket 33 fixed rotatably, and a handrail sprocket 34 fixed rotatably.
- the gear 27 is fixed coaxially with the handrail sprocket 33 that is rotatably fixed, the gear 27 can be rotated by the driving force from the sprocket 20. Further, the gear 27 engages with the moving handrail 9 so that the moving handrail 9 can be moved in synchronization with the step 17 without slipping.
- the moving handrail manufacturing apparatus and the manufacturing method thereof according to the present invention are suitable for manufacturing a moving handrail.
