The present invention relates to a retractable umbrella that can be attached above a door that opens to allow people to exit or enter an enclosure, such as, a bus, airplane, train, house, building, and the like. The retractable umbrella comprises several frames to which umbrella sheets are attached and that nest within one another within a housing that is attached to said enclosure. With a switch or button, a motor linearly displaces a shaft that displaces each of said frames out of the housing so as to provide protection for people from the rain as they exit or enter said enclosure.
