Abstract
A safety umbrella includes a top notch member fixed on an upper end of a central shaft and having a resilient tongue which extends downwardly to form a hook end with an actuated shoulder surface. A runner has a slot for retaining the hook end therein at an upper position. An operating sleeve surrounds and is axially movable relative to the runner and has an actuating friction block which is matingly engaged with the actuated shoulder surface at the upper position such that, when the operating sleeve is moved downwardly, the actuated shoulder surface is pressed to withdraw the hook end inwardly so as to disengage the hook end from the slot.
