Title:
ESCALATOR OF TYPE IN WHICH INTERMEDIATE SECTION THEREOF IS ACCELERATED
Document Type and Number:
WIPO Patent Application WO/2006/064675
Kind Code:
A1
Abstract:
A chain link (12) of a step chain (10) for endlessly connecting steps (3) has a fixed link (12a) and a movable link (12b). The fixed link (12a) connects a rear section fixation position (13a) near a rear wheel (5) and an intermediate section fixation position (13b) between a front wheel (4) and the rear wheel. The movable link (12b) connects a rear section fixation position of a preceding step of adjacent two steps and an intermediate section fixation section of the following step. Near an entry landing or exit landing, the intermediate section fixation position of each step moves along a circular-arc locus about a fulcrum that is the rear section fixation position of the preceding step, thereby a difference in height between the adjacent steps is reduced.
