Title:
CLEANING DEVICE FOR ESCALATOR AND ESCALATOR USING THE SAME
Document Type and Number:
Japanese Patent JP2011105406
Kind Code:
A
Abstract:

To provide a cleaning device for an escalator having superior portability and usable for both an ascending elevator and a descending elevator, and also provide an escalator using the cleaning device.

The pair of support parts 16, 16 of this cleaning device 1 rotatably support a shaft part 14 at both ends of the shaft part 14 in the axial direction W. A control unit 10 includes a friction roller 12 and a deceleration part 13, and is attached to the shaft part 14. The friction roller 12 is brought into contact with a step 5 to convert the linear motion of the step 5 to a rotary motion by a frictional force produced therebetween and output the rotary motion to the deceleration part 13. The deceleration part 13 reduces the speed of the rotary motion input from the friction roller 12 and outputs the speed to the shaft part 14, and rotates the shaft part 14 in the direction reverse to the rotating direction of the friction roller 12. A roller brush 15 is coaxially attached to the shaft part 14. The cleaning device 1 is mounted on the pair of side walls 4, 4 of the escalator, and the friction roller 12 and the roller brush 15 are brought into contact with the step 5.
