    摘要: A centering mechanism is provided for the front wheels of a wheelchair having pairs of front and rear wheels. The centering mechanism has particular applicability for racing wheelchairs, such as those used in marathon racing. Linkage is employed to form a parallelogram structure with hinged corners, upon which the front wheels of the wheelchair are mounted by means of stub axles. The linkage holds the front wheels mutually parallel to each other while the centering mechanism returns the front wheels to parallel alignment with the rear wheels upon release of a steering device.
