Abstract

The present invention includes a device for transporting an individual. The device includes a frame that supports a drive wheel and a chair movably attached to the frame for receiving the individual. The device also includes a lift mechanism attached to the frame. The lift mechanism includes a screw, a mechanism for moving the screw, and an arm for lifting the individual from the chair. The device further includes a pivoting mechanism attached to the arm of the lift mechanism for positioning the lifted individual radially about the screw. The device additionally includes a swivel mechanism attached to the pivoting mechanism on the arm of the lift mechanism, opposing the pivoting mechanism for swiveling the lifted individual. The device also includes a leg for stabilizing the transporting device, when the lift arm is pivoting left or right.

Claims

1. A patient transporter device comprising:

a frame that supports a drive wheel and a chair movably attached to the frame;

a lift mechanism attached to the frame, the lift mechanism including a screw, motor means for moving the screw, and an arm vertically moved by the screw;

a motorized pivoting mechanism attached to the arm of the lift mechanism for pivoting the arm radially about the screw; and

a swivel mechanism attached to the arm of the lift mechanism, said swivel mechanism including a motor adapted to rotate, around a vertical axis, a patient suspended from said swivel mechanism.

2. The device of claim 1 and further comprising a sling spreader attached to the swivel mechanism.

3. The device of claim 1 and further comprising a stabilizing mechanism, that includes a leg for stabilizing the transporting device upon activation of the pivoting mechanism.

4. The device of claim 1 and further including an actuator for actuation of at least one of the pivoting mechanism and swivel mechanism.

5. The device of claim 4 wherein the actuator actuates at least one of the lift mechanism, pivoting mechanism and swivel mechanism in a manner that is effective for pre-positioning an individual transported in the transporter.

6. The device of claim 1 and further including a weighing mechanism on the arm of the device.

7. A method for transporting a disabled individual, comprising:

positioning the individual in a device that includes a frame that supports a drive wheel and a chair movably attached to the frame, for receiving the individual;

a motorizing lifting mechanism attached to the frame, the lifting mechanism including a screw, a motor for moving the screw, and an arm vertically movable by the screw, for lifting the individual from the chair;

a motorizing pivoting mechanism attached to the arm of the lift mechanism for positioning the lifted individual radially about the screw;

a motorized swivel mechanism attached to the arm of the lift mechanism, said swivel mechanism including a motor adapted to rotate, around vertical axis, the lifted individual suspended from said swivel mechanism; and

moving the individual in the device by moving the drive wheel of the device.

8. The method of claim 7 and further including stopping rotation of the drive wheel and actuating the motor of the screw, thereby elevating the arm.

9. The method of claim 8 and further including transferring the individual from the chair to a suspended state in sling attached to the arm by the swivel mechanism.

10. The method of claim 9 and further including rotating the individual, once suspended, radially about the screw by rotation of the arm.

11. The method of claim 10 and further including pivoting the individual, while suspended.
