An oblong umbrella having a hood adapted to be extended oppositely so as to shield several people and which is foldable and extendable in a bellows manner for convenient handling and storage. An umbrella comprises a main shaft, an upper hub secured to the main shaft, a lower runner slidably inserted on the main shaft, main spokes connected to the upper hub, main stretcher links connected to the lower runner at inner ends thereof and to middle parts of the main spokes at the outer ends thereof, two upper frames connected to the upper hub which are projected oppositely, two lower frames connected to the lower runner which are connected to middle parts of the upper frames at middle parts thereof, an upper hinge connected to outer ends of the lower frames, a lower hinge connected to outer ends of the upper frames, second spokes connected to the upper hinges, second stretcher links connected to the lower hinge and to middle parts of the second spokes, and a hood secured to outer ends of the main and second spokes. In another embodiment, a mediate runner is disposed between the upper hub and the lower runner. Two frames are pivotally connected to both sides of the mediate runner to form a X-shaped configuration. The frames are each connected at a middle part of a half thereof to the outer end of an upper stretcher link connected to the upper hub and at a middle part of the other half thereof to the outer end of a lower stretcher link connected to the lower runner.
