Patent abstract

An improved walker includes an adjustable frame with angled portions that provide an ergonomic interface and enhanced stability for a user. The front of the walker includes a wishbone front support frame. Rather than incorporating multiple front legs extending from the top of the walker to the floor, the wishbone front support frame provides clearance on either side of a center front column. This clearance allows users to position, or maneuver, the walker close to adjacent objects. The handrail portions of the walker are pitched at a downward angle running in a direction from the rear to the front of the walker. This pitch moves the operating position of the user close to the front of walker providing a safe and stable operating position.
