A wheelchair is a manually operated or power-driven device designed primarily for use by an individual with a mobility disability for the main purpose of indoor, or of both indoor and outdoor, locomotion.
2.)
A doorknob is the knob or handle used to open and close a door. Doorknobs are common on doors, especially the inside doors of a home, such as the doors of different rooms and closets. These tend to be metal and shaped like a, well, knob—a part that sticks out and has a rounded end.
3.)
