A wheeled personal mobility device 100 is disclosed and is convertible between a number of reconfigurations, notably between a folded state (figure 1), a standing support walker or rollator (figure 4), a seated walker (figure 7) a wheelchair (figure 10). The configurations may be manually powered or power-assisted. The device is convertible between at least three possible configurations. The device may consist of a front chassis (2, figure 2) and a rear chassis (3, figure 2), the chassis rotatably coupled to each other and including respective wheel assemblies (30, 4, figure 4). The rear chassis may comprise two substantially spaced apart members being connected by a cross member (83, figure 2). A width adjustor may also enable the distance between the rear chassis members to be adjusted. The width adjustor may include a threaded barrel arrangement (17, 18, 58, 59, figure 3). A steering control 93 may be removably attached to the front chassis and operable to steer the front wheels. When removed, the steering control may be stowed within an internal compartment (87, figure 9) of the front chassis. The front chassis member may further be extendable to vary the wheelbase of the mobility device. |
