Problems solved by technology

[0003] Compared with the existing umbrellas that cannot be folded, the three-fold umbrella has the advantages of small size, convenient carrying and storage; and the four-fold umbrella, compared with the three-fold umbrella, it further reduces the volume of the entire umbrella, thereby further improving the carrying and storage capacity. It is convenient to carry when going out, but any support bone in the umbrella ribs in the four-fold umbrella is made of four rods hinged to each other, and adding a rod increases the sewing difficulty between the umbrella cloth and the support bone, thereby increasing the processing cost. The three-fold umbrella has the advantage of convenient processing, but the folded volume of the three-fold umbrella cannot achieve the effect of the four-fold umbrella, which directly affects the convenience of its use.

Abstract

A folding umbrella cloth supporting rib comprises a first rib rod, a second rib rod, a third rib rod and a fourth rib rod; the first rib rod, the second rib rod and the third rib are hinged end to endin sequence through hinge parts to form a linkage mechanism capable of rotationally folding around the hinged points; the fourth rib rod comprises an upper driven rib rod and a lower movable rib rodhinged end to end sequentially, a free end of the upper driven rib rod is hinged to the hinge part between the first rib rod and the second rib rod to form a single-axis double-parallel shear structure. Besides, the lower movable rib rod is hinged to the middle of the first rib rod, and the lower movable rib rod fits a free end of the first rib rod. With the single-axis double-parallel shear driving researched and utilized on the umbrella rib structure, the length of the hinged portion of the first rib rod and the second rib rod in a folding state can be shortened effectively, and thus the folding length of the umbrella cloth supporting rib in a folding state is shortened effectively on the premise of guaranteeing the same effective umbrella cloth application area.

Description

technical field [0001] The invention relates to the field of umbrella skeletons, in particular to a foldable umbrella fabric support frame, which can reduce the volume of the folded umbrella while ensuring convenient folding of the umbrella. Background technique [0002] Umbrella, which at least includes an umbrella handle, umbrella ribs and umbrella cloth, the umbrella cloth is sewn on the umbrella rib, and the umbrella rib is mounted on the top of the umbrella handle; the umbrella rib includes a plurality of umbrella cloth support ribs If the umbrella handle bar and each umbrella cloth supporting bone are folded, the three-fold and four-fold umbrellas sold on the market will be formed. [0003] Compared with the existing umbrellas that cannot be folded, the three-fold umbrella has the advantages of small size, convenient carrying and storage; and the four-fold umbrella, compared with the three-fold umbrella, it further reduces the volume of the entire umbrella, thereby fur...
