Abstract
An umbrella includes: a central shaft, and a rib assembly respectively pivotally secured to an upper notch formed on a top of the central shaft and to a runner slidably held on a guiding sleeve disposed about the central shaft; with the guiding sleeve integrally formed with a resilient protrusion on the sleeve; and the runner having a socket formed in the runner for engaging the resilient protrusion for opening the umbrella, and a sloping portion inclined upwardly inwardly from the socket for thrusting the resilient protrusion inwardly for disengaging the runner from the resilient protrusion on the guiding sleeve when lowering the runner for closing the umbrella, thereby omitting the lateral depression operation by inwardly depressing a spring catch of a conventional umbrella and thereby enhancing a safe, quick, and ergonomic operation for closing the umbrella.
