An improved retractable umbrella including a canopy, a plurality of extending arms for supporting the canopy, an outer housing having an interior cavity for housing the canopy and the plurality of extending arms, and a collapsing mechanism for pivoting the plurality of extending arms upwardly into a substantially vertical position from an open configuration to collapse the canopy upwardly into an inverted closed configuration thereby allowing retraction of the canopy and the plurality of extending arms into the interior cavity of the outer housing. In one embodiment, the retractable umbrella also includes a displaceable member positioned in the interior cavity of the outer housing and a center shaft extending into the interior cavity and being displaceable therewithin from outside of the outer housing. The displaceable member has a central opening through which the center shaft extends. The retractable umbrella also includes a plurality of extending arms pivotally mounted to at least one of the displaceable member and the center shaft and a plurality of support arms, each having a first end and a second end, the first end being hingably mounted to at least one of the plurality of extending arms and the second end being hingably mounted to the other of the displaceable member and the center shaft. A canopy is centrally supported at an end of the center shaft and peripherally supported at ends of the plurality of extending arms.
