Abstract:
A stair traversing device comprising a payload body for transporting a payload, a step frame, and a mechanism between the step frame and the payload body to move the step frame relative to the payload body along a cyclical path. The mechanism drives a movement of one of the payload body and the step frame along a first segment of the cyclical path from a retracted configuration to an extended configuration, and drives a movement of the other one of the payload body and the step frame along a second segment of the cyclical path back into the retracted configuration. The payload body and the step frame are configured to remain fixedly in position on a stair when the other one of the payload body and the step frame is moved. The mechanism is configured to maintain the relative orientation between the payload body and the stair.

Claim (Index 1):
A stair traversing device, comprising:\n a payload body configured for transporting a payload; a step frame; and a mechanism between the step frame and the payload body, the mechanism being configured to move the step frame with regards to the payload body along a cyclical path by:\n driving a movement of one of the payload body and the step frame relative to the other one of the payload body and the step frame along a first segment of the cyclical path from a retracted configuration in which the step frame and the payload body are both on a first level, to an extended configuration in which the step frame and the payload body are on two different levels; and \n driving a movement of the other one of the payload body and the step frame along a second segment of the cyclical path back into the retracted configuration in which the step frame and the payload body are both on a second level; \n wherein the step frame is configured to remain on the first or second level when the payload body is moved between the first level and the second level; and wherein the mechanism is configured to maintain the relative orientation between the payload body and the step frame.
