Abstract
An inversely foldable automatic umbrella includes a main shaft; an operating sleeve and a connecting sleeve mounted around the main shaft; a compression spring with two ends thereof contacting the connecting sleeve and the operating sleeve, respectively; a first canopy with a central portion thereof fixed to the operating sleeve; a second canopy with a central portion thereof fixed to the top end; a skeleton disposed between the first canopy and the second canopy; and a pull-moving mechanism having a sliding unit and a connecting unit. The sliding unit is slidingly disposed on the skeleton. Two ends of the connecting unit are pivotally disposed on the sliding unit and the operating sleeve, respectively. When the operating sleeve is at a folding position to fold up the first canopy and the second canopy, the skeleton is allowed to completely adhere to the main shaft.
