ABSTRACT:
A safety umbrella includes: a lower runner for pivotally connecting the ribs of the umbrella slidably held on a central shaft of the umbrella and formed with a latch hole in the lower runner; a controller formed in a grip of the central shaft having a push button normally protruding outwardly from the grip, and a latch connectable with the push button and resiliently urged by a restoring spring retained in the grip for operatively engaging the latch hole in the lower runner for locking the lower runner and the ribs at a folded condition, to thereby eliminate a long slot cut in the shaft above the grip to prevent deformation or damage of the shaft and to eliminate the acute spring catch formed in the shaft to prevent injury to the umbrella user as stuck by the conventional spring catch.
