A multifunctional mobility device for physically disabled people comprises a L-shaped frame having at its lower end a platform adapted to receive thereon a user in a substantially standing position. Front and rear wheels support the frame and the platform. The front wheels are rotatably mounted to the frame just in front of the platform. The frame includes at its upper end a pair of grips which can be grasped by the user when standing on the platform. Therefore, to operate the mobility device, the user must exert on the frame a sufficient force oriented substantially in a forward direction thereby producing a pivot of the frame and of the platform about the front wheel and a rotation of the front wheel which results in a forward displacement of the mobility device and of the user. A stabilizer terminated by a swivel caster is provided in front of the front wheels for limiting the forward pivot of the mobility device. A retractable seat also transforms the mobility aid into a wheelchair. The platform is then converted into a footrest. A second pair of grips is provided to be used by the attendant for pushing the user. The stabilizer can be retracted to allow the attendant to push the wheelchair on horizontal surfaces or along inclined surfaces, such as stairs or escalators. The mobility device is constructed of a number of connected members designed to fold for providing low profile mobility device for stowage and transportation purposes. |
