Abstract
An umbrella includes a runner sleeved slidably on a stem for spreading and collapsing a canopy which is mounted on a ferrule. A tubular member surrounds the stem, is fixed on the ferrule, and is formed with a retaining slot therein. An upper end portion of the runner is formed with a through hole which is aligned with the retaining slot longitudinally, and which can be registered with the same radially when the runner is moved to stretch the canopy. A lever member is pivoted to the runner at a fulcrum portion, and has upper and lower segments at two opposite sides of the fulcrum portion. The upper segment has an anchoring end portion to be received and retained in the retaining slot by the action of a biasing member when the canopy is stretched.
