Description

technical field

[0001] The present invention relates to an umbrella. Background technique

[0002] A common umbrella includes a middle stick with a fixed upper nest and a sliding lower nest, multiple sets of rib assemblies (each set of rib assemblies is pivotally connected to a set of slots of the upper nest and the lower nest of the middle stick), Umbrella cloth tied to the outside of each umbrella rib assembly. In windy weather, when the airflow blows from the inside of the umbrella cloth, the umbrella cloth and umbrella ribs will be folded outwards (commonly known as umbrella blooming), and in severe cases, the umbrella bones will be broken. For this reason, the industry proposes to divide the umbrella cloth into a polygonal upper umbrella cloth located in the center of the outer side of each umbrella rib assembly and a ring-shaped lower umbrella cloth located on the outer periphery of each umbrella rib assembly. The lower side of the upper umbrella cloth covers the lowe...
