Abstract

The present invention provides a comfortable passenger conveyer with little unpleasant pulse and noise of a handrail drive system. In the handrail drive system that moves a handrail at the same speed as running boards by obtaining power from the running board chain of the passenger conveyer including the running boards revolving in synchronization with the running board chain and incorporated in the running board chain at a constant interval, the running board chain being connected in an endless state to be revolved, a parapet standing along the travelling direction of the running boards, and the handrail provided to the parapet, the drive system of the handrail includes a drive unit and a power unit, the power unit is arranged above the running board chain on a lower running side, and the slide pin of the power unit is engaged with the running board chain at the right angles, thereby obtaining a power to drive the handrail.

Description

technical field [0001] The invention relates to a passenger conveying device, in particular to a driving mechanism for a handrail of the passenger conveying device. Background technique [0002] Passenger conveying equipment that carries passengers by moving a plurality of pedals is generally constructed such that the pedals are connected to endless pedal chains located on the left and right sides of the pedals through the shafts that the pedals have, and the pedal chains are wound around the main sprocket and the secondary chain. Between these two sprockets, the pedal is moved by applying a rotational force to one of the sprockets. In addition, in order to drive the armrest so that it moves synchronously with the pedals, a structure is adopted in which the driving force of the armrest is obtained from a chain or a sprocket that drives the pedals. [0003] As prior art related to passenger conveyance equipment that obtains driving force from the pedal chain, for example, th...
