Description

[Technical Field]

[0001] The present invention relates to the field of umbrellas, and more particularly to an ultra-lightweight five-fold four-fold umbrella. [Background technology]

[0002] Umbrellas are an essential tool in daily life, combining the functions of sun protection and rain protection. In recent years, due to climate change and increased awareness of sun protection, the demand for portable umbrellas has increased significantly, especially in urban commuting and outdoor travel. Umbrellas on the market are mainly divided into straight umbrellas, bi-fold umbrellas, tri-fold umbrellas, four-fold umbrellas, and five-fold umbrellas. However, the common four-fold umbrella ribs have the problem that when folded, the multiple connected ribs are stacked from the outside to the inside, resulting in an excessive volume after folding.

[0003] Therefore, the market urgently needs an ultra-lightweight five-fold four-fold umbrella that has a smaller folded volume, is lighter in weight, and does not affect functionality. Summary of the Invention [Problem to be solved by the invention]

[0004] To solve the above problems, this invention provides an ultra-lightweight five-section four-fold umbrella, and by optimizing the structure and material of the ribs, it meets the demands of lightweight and portable travel. [Means for solving the problem]

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] An ultra-lightweight five-section, four-fold umbrella, comprising a center pole, an upper section, a lower section and multiple sets of ribs, the center pole being made up of five short tubes connected together, each set of ribs comprising a support rib and a main rib, one end of which is pivotally attached to the upper section and the lower section respectively, the main rib comprising a first main rib, a second main rib, a third main rib and a tail rib; The other end of the auxiliary bone is hinged offset with respect to the central side of the first main bone, and the other end of the first main bone is connected to the second main bone via a first joint, the second main bone has a two-bone structure, the second main bone is connected to the third main bone via a second joint, and the third main bone is connected to the coccyx via a third joint, the third joint is an offset joint structure, and when the umbrella bone is folded, the auxiliary bone is folded to the side of the first main bone, and the coccyx is folded to the side of the third main bone.

[0007] Furthermore, both the auxiliary ribs and the main ribs are made of glass fiber or carbon fiber material.

[0008] Furthermore, the upper nest is fixedly attached to the tip of the center rod, and the lower nest is movably attached to the first stage short tube of the center rod.

[0009] Furthermore, a short loop is provided between the adjacent ends of the auxiliary rib and the second main rib to pull them together.

[0010] Furthermore, long loops are provided between the adjacent ends of the first main bone and the third main bone, and between the adjacent ends of the second main bone and the coccyx, to pull on each other. [Effects of the Invention]

[0011] This invention uses a lopsided folding design, allowing some of the ribs to fold sideways against the other ribs after folding, thereby reducing the umbrella's thickness after folding. The center rod design uses a multi-stage telescopic structure, connecting multiple short tubes in stages to shorten the umbrella's overall length after storage. The ribs are made of glass fiber or carbon fiber, which reduces the overall weight of the umbrella compared to conventional steel or aluminum ribs. At the same time, the two-rib structural design also increases the strength of the ribs. This solves the problem of multiple adjacent ribs stacking from the outside to the inside when folding a traditional umbrella, resulting in an excessively large volume after folding.

[0012] By integrating the above technologies, this invention significantly improves the lightness, portability and durability of umbrellas. This invention can be applied to both round-rib and flat-rib umbrellas. [Brief explanation of the drawings]

[0014] The technical means in the embodiments of the present invention will be described below clearly and completely with reference to the drawings of the embodiments of the present invention, but it is clear that the described embodiments are only some of the embodiments of the present invention and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative work fall within the scope of protection of the present invention.

[0015] As shown in Figures 1 to 11, this invention provides an ultra-lightweight five-section, four-fold umbrella consisting of a center pole 2, an upper nest 3, a lower nest 4, and multiple sets of ribs 1. The center pole 2 is made up of five short tubes connected to each other, and when the umbrella is folded, the five short tubes contract in stages, significantly shortening the overall length of the umbrella after folding. Each set of ribs 1 consists of a secondary rib 5 and a main rib 6, one end of which is pivotally attached to the upper nest 3 and the lower nest 4, respectively, allowing the ribs 1 to be suspended on the center pole 2. The main rib 6 includes a first main rib 6a, a second main rib 6b, a third main rib 6c, and a tail rib 6d. The other end of the auxiliary rib 5 is hinged offset from the central side of the first main rib 6a. The other end of the first main rib 6a is connected to the second main rib 6b via a first joint 9. The second main rib 6b has a two-bone structure, which improves the strength of the entire umbrella rib. The second main rib 6b is connected to the third main rib 6c via a second joint 10. The third main rib 6c is connected to the coccyx 6d via a third joint 11. The third joint 11 has an offset joint structure. When the umbrella ribs are folded, the auxiliary ribs 5 fold to the side of the first main rib 6a. The coccyx 6d folds to the side of the third main rib 6c, thereby reducing the thickness of the umbrella after it is stored.

[0016] Specifically, both the auxiliary ribs 5 and the main ribs 6 are made of glass fiber or carbon fiber material, which has the effect of reducing the weight of the entire umbrella.

[0017] Specifically, the upper nest 3 is fixedly attached to the tip of the center rod 2, and the lower nest 4 is movably attached to the first short tube of the center rod 2.

[0018] Specifically, a short loop 7 is connected between the adjacent ends of the auxiliary rib 5 and the second main rib 6b, pulling them together. A long loop 8 is connected between the adjacent ends of the first main rib 6a and the third main rib 6c, and between the adjacent ends of the second main rib 6b and the coccyx 6d, pulling them together. When the first main rib 6a and the auxiliary rib 5 are deployed outward, the second main rib 6b, the third main rib 6c, and the coccyx 6d are pulled by the short loop 7 and the long loop 8, and also deploy outward together. Similarly, by pulling the lower nest 4 downward, the umbrella can be retracted.

[0019] Operating principle and usage process of this device: To use this device, hold the bottom of the middle rod 2 and push or pull the lower nest 4 up or down to open or contract the ribs 1, thereby extending or contracting the middle rod 2. The upper nest 3 is fixedly attached to the tip of the middle rod 2, and one end of the auxiliary rib 5 is fixed to the upper nest 3, while the other end is connected to the middle of the first main rib 6a. The lower nest 4 is movably attached to the first short tube of the middle rod 2, and one end of the first main rib 6a is fixed to the lower nest 4, while the other end is connected to the second main rib 6b. When the lower nest 4 is pushed up, the first main rib 6a unfolds outward, simultaneously moving one end of the auxiliary rib 5 outward. A short loop 7 is provided between the adjacent ends of the auxiliary rib 5 and the second main rib 6b, which pull each other. A long loop 8 is provided between the adjacent ends of the first main rib 6a and the third main rib 6c, and between the adjacent ends of the second main rib 6b and the tailbone 6d, which pull each other.

[0020] When the first rib 6a and the auxiliary rib 5 are deployed outward, the second rib 6b, the third rib 6c and the tailbone 6d are pulled by the short loop 7 and the long loop 8 and deployed outward together. Similarly, by pulling the lower nest 4 downward, the umbrella can be retracted.

[0021] This device also uses a lopsided folding design, with the auxiliary ribs 5 connected to the sides of the first main rib 6a. When the umbrella ribs 1 are folded, the auxiliary ribs 5 are stored next to the first main rib 6a. The third joint 11 is a displaced folding joint, and when the umbrella is folded, the tail rib 6d folds to the side of the third main rib 6c, thereby compressing the umbrella's thickness after folding. The center rod 2 uses a five-stage nesting structure, with five short tubes that gradually contract when the umbrella is folded, significantly shortening the overall length after folding. The second main rib 6b has a two-rib structure, which increases the strength of the entire umbrella rib.

[0022] The above is merely a specific embodiment of the present invention, and the scope of protection of the present invention is not limited thereto, and any changes or substitutions that can be conceived without creative labor are also included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be equivalent to the scope of protection limited by the claims. [Explanation of symbols]
