Abstract: A balustrade device for a passenger conveyor, wherein a plurality of balustrade posts are erected at intervals apart in a direction of travel of steps. A plurality of outer decks abut against each other at positions of the balustrade posts. Recesses, through which the balustrade posts are passed respectively, are provided in the mutually adjacent end portions of the outer decks. Gaps are provided respectively between edges of the recesses and the balustrade posts. A plurality of cover members which close the gaps are provided on top of the outer decks. Each of the cover members is fixed to the balustrade post via a retainer which is fixed to an end surface of the balustrade post on a side of the step.

Abstract: A tread unit of a passenger conveyor includes: a tread, a tread reinforcing member and a riser which are made of fiber reinforced plastic made by knitting fibers together. The surfaces of the cleat portions of the tread and the riser are provided with surface treated layers in which the wear resistance and coefficient of friction are controlled. As a result of this construction, the aesthetic design of the tread unit and of the passenger conveyor system can be improved. In addition, the reduced weight of the tread unit contributes to labor-saving at the time of mounting, and a passenger conveyor system using these tread units can be reduced in size and weight as a whole.
