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 3):
The stair traversing device according to  claim 1 , wherein the mechanism further comprises:\n two arms disposed on both sides of the payload body, each arm having first end operatively connected to a driving shaft of the payload body and second end pivotally mounted to the step frame, the arms extending radially away from the driving shaft for rotation thereabout, the first segment of the cyclical path being defined by a partial turn of the arms around the drive shaft in a given direction, the second segment of the cyclical path being defined by another partial turn of the arms around the drive shaft in the given direction, the first segment of the cyclical path and the second segment of the cyclical path defining a full turn of the arms about the driving shaft.
