Patent

CA 2350973

A variable-speed moving walkway includes an array of support rollers (10) provided with a plurality of horizontal drive rollers (11), having upper surfaces arranged to be generally flush with each other and rotated about each axial center, and an endless belt (16), supported by the array of support rollers, for moving continuously by their rotation. An array of accelerating rollers (12), an array of high-speed rollers (13), and an array of decelerating rollers (14) constitute the array of support rollers, and allow rotational speeds of the horizontal drive rollers to gradually increase from a low speed, to be maintained at a constant high speed, and to gradually decrease to a low speed, respectively. In addition, the endless belt (16) readily extends or retracts in the direction of movement and barely extendable or retractable in the widthwise direction. The belt (16) extends and retracts in the direction of movement in response to the rotational speed of the horizontal drive rollers.
