Abstract
An escalator includes a main frame defining an elongated sloped circulating loop path having an upper load-bearing run and a lower return run and a plurality of steps disposed along the circulating loop path defined by a guide rail mounted to the main frame for guiding the steps. A transmission mechanism is disposed on the steps for transmitting a power from a drive unit. Each of the steps has a pin and a slot formed in an edge portion of the step to extend along the edge portion of the step. One end of a link is pivotally connected to the pin of the step and the other end of the link is slidably engaged by the slot in the link of the neighboring step, whereby the steps are connected together so that the distance between the respective steps can be varied.
