Abstract: A four-segment foldable umbrella comprises a shank, a rib assembly, an opening spring, a closing spring, a control mechanism, and a plurality of gores. The shank further comprises a top fulcrum, an outer pipe, a second middle pipe, a first middle pipe, an inner pipe, a handgrip. a long plastic pipe, and an outer pipe plug. The rib assembly consists of a plurality of top stretchers, lower ribs, inner connection ribs, middle ribs, inner resilient ribs, small slide sockets, outer resilient ribs, outer connection ribs, tail ribs, and a runner. An upper end or a lower end of the opening spring sustains a lower end of the outer pipe plug or props a long controller at its upper end respectively.

Abstract: An automatic umbrella control mechanism, which includes a socket defining a receiving chamber, a receptacle supported on a compression spring in the receiving chamber inside the socket, a hook turned about a pivot in the socket and supported on a torsional spring at the pivot, a button controlled to turn the hook for enabling the folding collapsible umbrella frame to be opened by a return spring, and a retainer bit to be retained to secured in position by a pressure spring to hold the umbrella in the open position. When the button is depressed again, the retainer bit is released from the constraint, enabling the umbrella to be collapsed by means of the operation of the return spring.
