Abstract
A device for enabling a wheelchair user to enter and exit the wheelchair includes a stabilizing frame. The stabilizing frame has two slide rails to which a base plate is movingly attached. An electric motor drives a leadscrew, causing the base plate to move along the slide rails. A telescopic column is vertically mounted onto the base plate. The seat assembly, including handlebars and a seat platform, is rotationally attached to the top of the telescopic column. The telescopic column is extended and collapsed by a linear actuator, raising and lowering the seat assembly. A stationary non-rotational rod is vertically mounted onto the telescopic column. When a user sitting on the seat platform exerts a moment force on the stationary rod, the seat assembly rotates about the stationary rod. A locking mechanism prevents the seat assembly from rotating when the user is transferring to or from the seat platform.
