[0002] Chinese patent number "CN118021041A" discloses an umbrella that is easy to fold and store, which includes: a telescopic umbrella pole, an umbrella rib assembly, and an umbrella cloth assembly. When the umbrella rib assembly is in a retracted state and the telescopic umbrella pole is shortened, the umbrella handle end forces the tail sliding rod and the middle sliding rod to approach the umbrella cap end, and the head annular umbrella cloth, the middle annular umbrella cloth and the tail annular umbrella cloth are stacked in sequence from the outside to the inside; when the telescopic umbrella pole is extended, the umbrella handle end forces the tail sliding rod and the middle sliding rod to move away from the umbrella cap end, and the middle annular umbrella cloth and the tail annular umbrella cloth are pulled out from the head annular umbrella cloth. The invention divides the traditional circular umbrella cloth into multiple independent parts, each of which is an annular structure of different diameters. After the umbrella is retracted, the independent parts of each annular structure will be stacked in sequence from the outside to the inside, thereby achieving the purpose of further reducing the space occupied by the umbrella.
