Abstract

A wheelchair 1 is adapted for one handed operation by incorporation of a foot operated steering means that allows a user to steer a steerable castor 6 by swivelling a footplate 8. A drive means 15 between footplate 8 and the steerable castor 6 is adapted to translate an angle of swivel of the footplate 8 about a swivelling axis 14 to a greater angle of rotation of the steerable castor 6 about a steering axis 21. Typically the ratio of footplate swivel to steerable castor rotation is around 1:2. The wheelchair 1 also has a drive wheel 3 incorporating a differential 41 that allows both drive wheels 3, 4 of the wheelchair 1 to be driven from just one hand rim 42. The drive wheel 3 has a brake 59 for locking the differential 41 such that the wheelchair 1 can pirouette on the spot. Both the differential 41 and the brake 59 are incorporated in a quick release arrangement, such that the drive wheel 3 can be easily removed from the wheelchair 1 for transport and stowage.
