The present invention relates to an electric wheelchair having a voice recognition drive system comprising: a traveling apparatus main body unit which has a plurality of wheels in a lower end thereof; a seating unit which is installed in an upper end of the traveling apparatus main body unit so as to be able to be lifted; an auxiliary robot leg unit which is able to be inserted into and protrude from the traveling apparatus main body unit, and which includes multi-joint driven by an external force; and a voice recognition drive unit which extracts a preset command from an externally input voice, and which drives the plurality of wheels, lifts the seating unit, and drives the auxiliary robot leg unit.

A swing arm assembly for a foldable wheelchair consisting of a camber tube and adapters is disclosed. The adapters mount to the frame of the wheelchair and receive the ends of the camber tube. One end of the camber tube is pinned into an adapter such that it pivots. The other end is pinned in an adapter using a quick release pin. The camber tube improves the stability of the foldable wheelchair. When desired to fold the wheelchair, the quick release pin is removed and the camber tube is rotated approximately 90 degrees, thereby allowing the wheelchair to fold. The adapters may be mounted to the wheelchair frame or to stub axles if used. The swing arm assembly adds substantial stiffness and stability to a folding wheelchair.

The present disclosure discloses a chair and a chair base. The chair base comprises a connection pipe, four support legs, and two C-shaped swinging rods. The four support legs are respectively disposed along four directions. The two support legs disposed in a left-to-right direction are fixedly connected to the connection pipe, and lower sides of middle portions of the two support legs are respectively disposed with a hinge piece. The two support legs disposed in a front-to-rear direction are rotatably connected to the connection pipe and comprise sliding sleeves. Two ends of the two C-shaped swinging rods are respectively rotatably connected to the hinge pieces of the two support legs disposed in the left-to-right direction. Middle portions of the two C-shaped swinging rods are respectively connected to the sliding sleeves of the two support legs disposed along the front-to-rear direction through link rods.

A mobile object of the invention includes: a moving base including a front wheel and a rear wheel; a seat having a seating surface; and an armrest located outward of the seating surface in a width direction of the mobile object. The armrest includes: a supporting part supported on the moving base; a body part supported by the supporting part; and a grip protruding from the body part. The armrest is configured so as to be changeable between the position of use in which a user seated on the seating surface can hold the grip with the arm positioned upward of the armrest, and the lift-up position in which the grip is positioned upward of the position of use. The grip in the lift-up position is located outward in the width direction of the mobile object with respect to the grip in the position of use.

The grip in the lift-up position is located outward in the width direction of the mobile object with respect to the grip in the position of use.

The wheelchair includes a pair of body frames and, wheels, cross bars, and a seating portion. The wheels are supported rotatably with respect to the pair of body frames by the pair of body frames. The cross bars are provided so as to extend in the Y-direction across the pair of body frames. The seating portion is attached to the pair of body frames and is the portion on which the wheelchair user sits. In the wheelchair, the body frame and the body frame are movable in the longitudinal direction of the cross bars, respectively. The distance between the body frame and the body frame can be changed by moving the body frames in the longitudinal direction of the cross bars.

A patient transport apparatus for transporting patients in a stair configuration and in a chair configuration. A multiple mode handle assembly is provided for user engagement, and is movable between a first handle configuration, a second handle configuration, and a third handle configuration.

A patient transport apparatus operable by a user for transporting a patient along stairs. A seat section is coupled to a support structure supporting a track assembly having a belt. A motor selectively generates torque to drive the belt. A user interface is arranged for engagement by the user, and has a direction input control for selecting a drive direction of the motor, and an activation input control for operating the motor to drive the belt. A controller in communication with the motor and the user interface is configured to limit operation of the motor in response to user engagement of the activation input control preceding engagement of the direction input control to prevent driving the belt, and to permit operation of the motor in response to user engagement of the activation input control following engagement of the direction input control to drive the belt in a selected drive direction.

A method and apparatus for assisting a patient from a sitting to standing position is disclosed, which includes: a base having caster wheels; a double scissors truss; a first motor operable to cause the double scissor truss to extend/retract vertically from the base; a first middle frame connected to the double scissor truss; a second middle frame hingedly connected to the front side of the first middle frame and is configured to be raised at an angle with the first middle frame; a seat member having a curved protrusion configured to assist the patient.
