An umbrella assembly is described in which a spring assisted movement of a knob away from or toward an umbrella handle respectively deploys or retracts a canopy and a plurality of support ribs. In the deployed position, each rib curves and keeps the canopy under tension. Elastic potential energy of a spring located within a body interior space deploys or retracts the ribs and canopy out of or into the body interior space, respectively.

An umbrella including a support shaft, a plurality of ribs, a rotatable cam assembly, and a canopy. Each rib of the plurality of ribs has a proximal end portion and a distal end portion. The proximal end portion is pivotably attached to an upper portion of the support shaft to pivot the rib between an open position and a closed position. The rotatable cam assembly includes a cam configured to rotate about a longitudinal axis of the support shaft. The cam is engaged with each rib of the plurality of ribs such that (i) each rib moves in a direction from the closed position to the open position when the cam rotates in a first direction and (ii) each rib moves in a direction from the open position to the closed position when the cam rotates in a second direction, the second direction being opposite the first direction.

The present invention may provide a wallet-type portable umbrella comprising: an umbrella including a grip portion; a case including a storage portion which includes a storage space in which the umbrella is accommodated, and a cover portion which can be fastened to the grip portion and opens and closes the storage portion; and a coupling unit for fastening the grip portion and the cover portion.
