We claim the ornamental design for a self-operating wheelchair lift, as shown and described.
|
FIG. 1 is a perspective view of a self-operating wheelchair showing our new design;
FIG. 2 is a front elevational view thereof, the rear elevational view being identical thereto;
FIG. 3 is a left side elevational view thereof, the right side elevational view being a mirror image thereof;
FIG. 4 is a top plan view thereof; and,
FIG. 5 is a bottom plan view thereof.
The broken line showing of a wheel chair in FIG. 3 is for illustrative purposes only and forms no part of the claimed design.
