Umbrella rib of multi-folding umbrella

Abstract

An umbrella rib of a multi-folding umbrella comprises a main rib body (1), one or more middle rib body (2) and a tail rib body (3) from inside to outside, wherein the main rib body (1), the one or more middle rib body (2) and the tail rib body (3) are sequentially connected. At least one middle rib body (2) is composed of two flexible branch rib main bodies (21) which are arranged side by side, the middle portions of the two branch rib main bodies (21) are connected through a connecting element (7), and a seam (22) for a pull rope (6) to pass is formed between the two branch rib main bodies (21); the two ends of the pull rope (6) are located above the branch rib main bodies (21), and the middle portion of the pull rope (6) penetrates through the seam (22) and is limited on the lower portion of the connecting element (7); an umbrella rib unit is opened until the pull rope (6) is basically straightened, and the middle portions of the two branch rib main bodies (21) arch upwards. The shape of the umbrella surface is full and attractive when the umbrella rib of the multi-folding umbrella is in an open state, and meanwhile the umbrella rib has the advantages of being resistant to wind and good in stability.

Description

technical field [0001] The present invention relates to an umbrella structure for daily use, in particular to an improvement of the rib structure of a multi-fold umbrella. Background technique [0002] In the existing multi-fold umbrella, the structure of the rib unit is usually formed by connecting the inner main groove bone and the short groove bone, the middle middle bone and the outer coccyx bone, wherein the main bone and the middle bone usually adopt a single The metal ribs or plastic ribs have low lateral stability, which can easily cause left or right sideways phenomenon, thereby affecting the opening and closing of the umbrella. In addition, in the existing multi-fold umbrella structure, if it is a three-fold umbrella, the connection between the main groove bone and the middle bone, if it is a four-fold umbrella, the position of the connection between the adjacent middle bones is lower. When the umbrella cloth is loaded onto the umbrella rib, the umbrella cloth wil...

In addition, in the existing multi-fold umbrella structure, if it is a three-fold umbrella, the connection between the main groove bone and the middle bone, if it is a four-fold umbrella, the position of the connection between the adjacent middle bones is lower. When the umbrella cloth is installed on the umbrella rib, the umbrella cloth will be recessed downward at the lower part of the position, thus making the shape of the umbrella surface not smooth enough and not beautiful
