Description of the invention: [Technical field of the invention] The present invention relates to an improved structure of a four-fold umbrella structure, in particular to a reinforced rib, which is easy to assemble and has a volume after folding. The small four-segment folding umbrella. 5 [Prior Art] According to the current field of umbrella technology, there are many umbrellas that are improved for the structure of the folding umbrella. The typical four-section folding umbrella structure, such as the publication No. 241471, is for umbrellas. The bone structure was improved, but the improvement was made for the main ribs (1). The folding joints were still pivoted by the general riveting method. Not only the manufacturing process was completed by the complicated riveting process and semi-manual operation. And the quality of the joints of the joints is not easy to control, and a folding umbrella has at least dozens of pivot joints, as long as one of the pivot joints has poor quality control in manufacturing, that is, an umbrella that is enough to cause a four-fold folding umbrella. After the bone is used for a period of time, it is easy to cause the pivot joint to rust and become stuck, and the riveting part is also the stress concentration. The slight force is 15 which is easy to cause the umbrella fracture to break. Although the umbrella made of FRP (Fiberglass Reinforced Plastics) can solve the problem that the rivet ribs are easy to rust, the rib structure of the FRP umbrella is checked to take into account the support stress of the umbrella frame. Generally, the round bar body is made, and in order to make the FRP round bar body pivotally connected with the umbrella seat 20 and the rib, the two ends of the FRP round bar body and the middle part need to be respectively connected with plastic connections. The components and the pivoting components, which cause the umbrella frame to be quite large, cause difficulties in collection, packaging and transportation. Therefore, the general FRP umbrellas are made of large-sized golf umbrellas that are not folded, so the FRP umbrella has been developed. For more than 20 years, but the FRP umbrella can still be closed, the reason is still not to be asked, 'not the reason ・1250000 124-061TWP -5/22 since. * In view of this, the inventor of the present invention has continuously improved the hairpin and finally broke through the bottleneck of the manufacturing technology of the FRP umbrella, and invented a brand new four-fold umbrella frame improvement-structure. 5 [Summary of the Invention] It is an object of the present invention to provide an improved structure of a four-fold umbrella structure, which is an umbrella that is smooth and not easily jammed when folded. • Another object of the present invention is to provide a four-fold umbrella structure improved structure that is lightweight and convenient for collection, packaging, and transportation. It is still another object of the present invention to provide a four-folded umbrella skeleton improved structure which further enhances the skeleton of the rib. In order to achieve the above objects and effects, the technical means adopted by the present invention comprises a folding umbrella body, the folding umbrella body comprising a spindle rod having an equiangular distribution on a plurality of split slots.

The third tie rod 70 is connected to the third pivot member 42 of the second main rib 16 and the fourth pivot member 33 of the fourth main rib 18, and the third pull rod 70 is formed with two ends -11 - 1250000 124-061TWP-12/22 The first hook portion 71, the second hook portion 72, and the meandering portion 73 of the intermediate portion are c-shaped, and the first hook portion 71 is hooked on the protrusion The U-shaped ring 425 of the third pivot member 42 is hooked in the through hole 3302 of the curved flat portion 3301 of the fourth pivoting member 33, and the bent portion 73 is passed through the hole. The fifth main rib 17 is positioned by the ring 170 such that the second main rib 16, the third main rib 17, and the fourth main rib 18 are mutually attracted. The improved structure of the four-fold umbrella structure of the present invention is formed as shown in FIG. 4 when the user uses the umbrella body 10 to be deployed; and when the user folds the folding umbrella body 1 , the image is formed as shown in FIG. In this state, the lower nest 13 will slide down 10 along the main shaft 11 at the same time, and at the same time, the supporting rib 15 will form a pulling force downward, so that the first main rib 14 and the rib 15 are formed in one direction. The strength of the lower swing, and the arrangement of the interlocking between them causes the second main rib 16, the third main rib 17 and the fourth main rib 18 to be folded downward downward to form a four-stage folding type. In such an embodiment, the four-fold umbrella of the present invention can achieve rapid and smooth deployment or folding. 15 It should be noted that the inner end extensions of the second, third and fourth pivot members 31, 32, 33 of the "four-fold umbrella structure improvement structure" of the present invention each form a curved flat portion for the ribs to be received. The folded volume can be reduced; and the first, second, third and fourth sets of pivot members 40, 41, 42, 43 are pivoted relative to the first, second, third and fourth pivot members 30, 31, 32, 33 One side is provided with a concave portion 407, 417, 427, 2〇 437, so that the rib is folded more smoothly, and the ribs can be folded in parallel after being folded, so that the volume of the rib is greatly reduced after being folded. As shown in Figure 5. In summary, the "four-fold umbrella structure improvement structure" of the present invention mainly uses the first to fourth main ribs to form a pivotable relationship between the pivotal members and the pivot members, and borrows By the action of the first to third tie rods, the four-stage folding of -12 - 1250000 124-061TWP-13/22 can be formed smoothly, and the combination of the umbrellas of the FRP folding umbrella can be realized. There is no rivet, and there is no problem of rust and stagnation, which makes the folding umbrella skeleton more durable and durable, so as to achieve the effect of making the folding umbrella more smooth and smooth, and so on. It is indeed a very excellent invention. The invention is not limited to the preferred embodiments of the present invention, and any changes in the technical means of the present invention should fall within the scope of the patent application of the present invention.
