Kind Code:
A1
Abstract:
An umbrella structure comprises a middle stick (1), an upper runner (2), a lower runner (3), an umbrella rib device and an umbrella fabric (5). The upper runner is fixedly disposed at an upper end of the middle stick. The lower runner is slidably disposed on the middle stick. Main umbrella ribs (41) of the umbrella rib device are pivotally connected to the upper runner. Each auxiliary umbrella rib (42) of the umbrella rib device is provided with a first connecting end (421) and a second connecting end (422). The first connecting end is pivotally connected to the middle section of the corresponding main umbrella rib, and the second connecting end is pivotally connected to the lower runner. The umbrella fabric is fitted to the main umbrella ribs of the umbrella rib device. Positioning parts which are in concave-convex fit when the umbrella is folded and unfolded are respectively disposed at pivot joints of the first connecting ends of the auxiliary umbrella ribs with the middle section of each main umbrella rib or pivot joints of the second connecting ends of the auxiliary umbrella ribs with the lower runner. The umbrella structure is simple and is highly wind-resistant and resistant to turning inside out. Therefore, the umbrella is safer to use, and can be recycled conveniently.
