Eccentric umbrella

Abstract

An eccentric umbrella includes a shaft and a runner is movably mounted to the shaft. A frame extends laterally from the shaft and is located between the top of the shaft and the runner. The frame includes a first top member and a bottom member. A rib unit is connected to the first top member and the bottom member, and supports the gore of the umbrella. The center of the gore is located eccentrically relative to the shaft. A positioning portion has a first end pivotally connected to the rib unit on two sides of the frame. A second end of the positioning portion is pivotably connected to the top of the shaft, a second top member on the top of the shaft, the runner or a positioning link on the frame. The eccentric umbrella provides sufficient coverage to the user when using the eccentric umbrella.
