AUTOMATIC UMBRELLA Abstract of the Disclosure A full self-opening and partial self-closing umbrella comprising an upper rib linkage runner and a lower latch runner slidable on a collapsible center- post. A cord passes over a pulley fixed to the centerpost's top end, one cord end being connected to the rib linkage runner and the other cord end being connected to the latch runner. The umbrella's center- post and rib linkage self-opens in response to a centerpost spring when the rib linkage runner is released from its storage position because the latch runner is held in its storage position, i.e., one end of the cord is held in a fixed position, while the rib linkage runner is allowed to move up the centerpost during the opening step. In the opened position, and when the latch runner is released, the rib linkage runner is no longer held in place by the cord. This causes closure springs which are part of the rib linkage to collapse the ribs toward the centerpost as the rib linkage runner slides down the centerpost, and as the latch runner slides up the centerpost to intermediate closure positions. Thus the umbrella's cover and rib linkage is collapsed, but the centerpost is still fully extended. The centerpost is then itself collapsed against the bias of the extension spring until the rib linkage and latch runner are latched in position adjacent the umbrella's handle. The umbrella also includes a spring guide rod with a cushion device for cushioning the impact forces exerted by the centerpost extension spring as the umbrella is opened. Also, the umbrella includes a safety hook that engages the linkage runner if the umbrella's push button is inadvertently pushed when the umbrella is closed and the umbrella's cover is wrapped with a closure strap. The safety hook pre- vents the umbrella from opening prematurely when the closure strap is released.
