ABSTRACT:
A multiple-fold automatic umbrella includes: a control device having a ring-shape push button slidably held in the grip having an upper latch integrally formed on a ring portion of the push button which is engaged with a slot formed in a lower runner slidably held on a central shaft of the umbrella for locking the runner and central shaft at their folded state, and which is disengaged from the slot of the runner for opening the umbrella when depressing the push button; and an elongated cylinder of an anti-false operation safety device resiliently held in the grip having a lower latch resiliently formed on a lower portion of the cylinder for preventing unexpected depression on the lower latch and only after the umbrella is opened, the lower latch may then be actuated, upon depression of the push button, for closing the umbrella from an opened umbrella, thereby providing an automatically opening and closing umbrella with simplified structure and minimized elements for the control device of the umbrella.
