Abstract
PURPOSE: To provide a passenger conveyor system, in which flanges are provided on both sides of rollers having tyre, and size of said flanges is smaller than that of the tyre by an amount smaller than the depth of engagement between teeth (7a) and cleat (5), whereby it is enabled to prevent that accident be caused when the tyre is ruptured.
CONSTITUTION: Flanges 8 of steel plate are provided on both sides of roller 3, and diameter of said flange 8 is selected such that it is retracted inwards from the rolling surface of tyre 3b by an amount B smaller than distance A shown in the drawing. With such an arrangement, if rupture of tyre 3b is caused, flanges are brought into rolling contact with guide rail 1. Under such circumstances, step tread 2 is lowered but teech 7a engage into cleat 5 by an depth equal to the difference between distances A and B. Therefore, if repture of tyre 3b is caused, it is prevented that passengers be accidentally caught between teech 7a the step tread 2.
