Abstract: A motorized door opening device, including at least one wheel, configured to be lowered to a surface and forced thereagainst with a force sufficient to ensure friction between the wheel and the surface and to prevent slipping of the wheel relative to the surface; an electric motor including a rotor coupled to rotate the wheel; a wheel actuator, coupled between the door and the wheel, to lower the wheel to the surface in response to a wheel lowering signal; and control circuitry to signal the wheel actuator to lower the wheel by generating the wheel lowering signal and push down the wheel to create friction; and a door attachment member to attach the motor and the wheel actuator to a bottom part of the door; whereby rotation of the wheel after lowering of the wheel causes the wheel to rotate in contact with the surface and move the door.

Abstract: A rolling footrest is provided and a method of using such by a wheelchair occupant. The footrest may optionally include a foot retainer, a platform and freely rolling castors. In some embodiments, replacing a fixed footrest will shorten the length of the wheelchair enabling the wheelchair to traverse sharp curves. In some embodiments, the footrest may include a swivel lock and/or a ratchet. In some embodiments the footrest may be used for therapeutic exercise. In some embodiments, the footrest may be used for propelling a wheelchair.
