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 42):
A method for traversing a stair using a stair traversing device, the 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 method comprising, with the mechanism:\n a) moving one of a payload body and a step frame with regards to another one of the payload body and the step frame along a cyclical path from a retracted configuration in which the payload body and the step frame are both on a first level of the stair to an extended configuration in which the payload body and the step frame are on two different levels of the stair; \n b) moving the other one of the payload body and the step frame along the cyclical path back to the retracted configuration in which both the payload body and the step frame are on a second level of the stair; and \n c) maintaining a relative orientation between the payload body and the stair during steps a) and b).
