Abstract (en)
[origin: WO2017122010A1] Traditionally, wheel chairs are provided with drive wheels with a push ring about a common hub for use by a user to drive the wheel chair. To gain more mechanical advantage users have tended to use the drive wheels directly which is dirty and can lead to trapped fingers. With the present invention push rings (9) on separate hubs (21) are provided with a mechanical coupling to the drive wheel (3). The push ring (9) can be inside or outside of their respective drive wheel (3), forward of, along with above, the drive wheel (3) for user convenience. The mechanical coupling will have a gear combination to improve performance.
