Safety umbrella

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.

AI Technical Summary

Benefits of technology

The present invention provides an umbrella that can be operated safely and conveniently without any risk of injury to the user and the canopy during operation. The umbrella has a simple and rigid structure that allows for the canopy to be spread and collapsed with ease.

Problems solved by technology

However, when a user presses the distal hook end for downward movement of the runner, the user's finger may get hurt, especially for children.

Moreover, wire ends of a fastening wire wound on the ferrule for pivotally connecting the ribs to the ferrule, and wire ends of a fastening wire wound on the runner for pivotally connecting the stretchers to the runner expose may prick the canopy and the user's hand and finger during opening or closing of the umbrella.
