Description

Technical Field

[0001] The present invention relates to the technical field of windproof umbrellas, and particularly to foldable windproof umbrella ribs.

Background Art

[0002] An umbrella is a rain protection tool most commonly used when going out on rainy days. In normal rainy days, an ordinary umbrella can sufficiently prevent rain and protect people from the rain. However, when hit by bad weather accompanied by strong winds and heavy rains, ordinary umbrellas expose a serious problem. That is, they cannot withstand strong winds. When a gust of wind blows, an ordinary umbrella will instantly turn over, the surface of the umbrella will be folded back in the opposite direction, and due to the application of a strong external force, the framework may bend or deform, or even be completely broken. In such a situation, the user will not only get wet in the rain but also lose the umbrella itself. Therefore, we propose foldable windproof umbrella ribs to solve this problem.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In the prior art, when a gust of wind blows on a rainy day, an ordinary umbrella has the disadvantages that the surface of the umbrella is folded back in the opposite direction, and due to the application of a strong external force, the framework may bend or deform, or even be completely broken.

Means for Solving the Problems

[0004] In this invention, a tension spring is attached between the adjacent ends of the receiving bone and the inner main bone. The supporting bone effectively controls the inner main bone, and by maintaining a firmly stretched state when the umbrella is deployed, it prevents loosening and deformation of the umbrella ribs. The middle main bone and the tail bone adopt a flat belt-shaped design structure made of fiber, which exhibits excellent wind resistance performance even under strong winds. Even if it bends backward due to strong winds, it can return to its original shape without deformation or damage. This significantly improves the wind resistance and stability of the umbrella ribs, extends the durability of the umbrella, and makes the umbrella ribs less likely to be damaged even during strong winds. It relates to a foldable wind-resistant umbrella rib.

[0005] The foldable wind-resistant umbrella rib according to this invention is composed of a foldable umbrella rib frame, a middle rod, an upper pulley, and a lower pulley. The upper pulley is fixedly installed at the top end of the middle rod. The lower pulley is movably mounted on the middle rod and is located below the upper pulley. The umbrella rib frame is connected between the upper pulley and the lower pulley by a pivotal connection method. The umbrella rib frame is composed of multiple sets of main bones and receiving bones. The main bones include an inner main bone, a middle main bone, and a tail bone. One end of the inner main bone is pivotally attached to the upper pulley, and the other end is pivotally connected to the middle main bone. The other end of the middle main bone is connected to the tail bone. One end of the receiving bone is pivotally attached to the lower pulley, and the other end is connected to the central part of the inner main bone. A tension spring is installed between the adjacent ends of the receiving bone and the inner main bone. The middle main bone and the tail bone adopt a flat belt-shaped structural design.

[0006] Preferably, the main bones and the receiving bones are made of glass fiber or carbon fiber.

[0007] Preferably, the receiving bone is connected to the central part of the inner main bone via Joint I, the inner main bone is connected to the middle main bone via Joint II, and the middle main bone is connected to the tail bone via Joint III.

[0008] Preferably, short connecting wires that attract each other are connected between the adjacent ends of the receiving bone and the middle main bone.

[0009] Preferably, long connecting wires that attract each other are connected between the adjacent ends of the inner main bone and the tail bone.

[0010] Compared with the prior art, the effects of the present invention are as follows. In the present invention, the receiving bone is connected to the central part of the inner main bone through joint I, generating a supporting effect on the inner main bone, and a tension spring is attached between the receiving bone and the adjacent end of the inner main bone to maintain tension when the umbrella is opened, avoiding loosening and deformation of the framework. The umbrella rib frame is manufactured by adopting glass fiber or carbon fiber. The middle main bone and the tail bone have a unique flat strip-shaped design, which provides better wind resistance performance in strong winds. When encountering strong winds, the supporting bones effectively support the inner main bone. The middle main bone and the tail bone have a unique flat strip-shaped design. Even if they are bent backward by strong winds, due to their excellent flexibility, the umbrella ribs will finally return to their original shape without deformation or damage. The wire structure plays a role of additional support and reinforcement under strong winds, further improving the wind resistance performance of the umbrella ribs. With such a comprehensive design, the present invention not only greatly improves the wind resistance performance and stability of the umbrella ribs, but also improves the durability of the umbrella, making it less likely to be damaged even under strong winds.

Embodiments for Carrying out the Invention

[0012] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, and in the drawings, the same or similar reference numerals consistently indicate the same or similar elements, or elements having the same or similar functions. The description of the embodiments with reference to the following accompanying drawings is merely illustrative and is for the purpose of explaining the present invention, and does not limit the present invention.

[0013] As shown in FIGS. 1 to 7, the present invention provides the following technical solutions. The foldable wind-resistant umbrella ribs are composed of a foldable umbrella rib frame 1, a middle rod 2, an upper pulley 3, and a lower pulley 4. The upper pulley 3 is fixedly installed at the top end of the middle rod 2, the lower pulley 4 is movably mounted on the middle rod 2 and is located below the upper pulley 3, and the umbrella rib frame 1 is connected between the upper pulley 3 and the lower pulley 4 by a pivoting method. Based on the above structural design, by pushing the lower pulley 4 up or down, the opening and closing of the umbrella ribs can be controlled. The umbrella rib frame 1 is composed of a plurality of sets of main ribs and receiving ribs 5, and the main ribs have an inner main rib 6, a middle main rib 7, and a tail rib 8. One end of the inner main rib 6 is pivotally connected to the upper pulley 3, the other end is connected to the middle main rib 7, the other end of the middle main rib 7 is connected to the tail rib 8, one end of the receiving rib 5 is pivotally attached to the lower pulley 4, and the other end is connected to the central part of the inner main rib 6. A tension spring 14 is attached between the adjacent ends of the receiving rib 5 and the inner main rib 6 to maintain tension when the umbrella is opened and avoid loosening and deformation of the framework. The middle main rib 7 and the tail rib 8 are designed in a flat strip shape, and this shape provides better wind resistance performance in strong winds. When encountering strong winds, the support rib 5 effectively supports the inner main rib 6. The middle main rib 7 and the tail rib 8 feature a unique flat belt-like design. Even if bent backward by strong winds, due to their excellent flexibility, the umbrella ribs will ultimately return to their original shape without deformation or damage. The wind resistance performance and stability of the umbrella ribs are significantly improved. Moreover, the durability of the umbrella is extended, making it less likely to be damaged even under strong winds.

[0014] Specifically, the main rib and the support rib 5 are made of glass fiber or carbon fiber and are manufactured with reinforcement materials.

[0015] Specifically, the support rib 5 is connected to the central part of the inner main rib 6 via the joint I9. The inner main rib 6 is connected to the middle main rib 7 via the joint II10, and the middle main rib 7 is connected to the tail rib 8 via the joint III11.

[0016] Specifically, a short wire 12 that attracts each other is connected between the adjacent ends of the support rib 5 and the middle main rib 7. When the support rib 5 and the inner main rib 6 are deployed, they are simultaneously deployed by the traction of the short wire 12. The wire structure plays a role of additional support and reinforcement under strong winds, further improving the wind resistance performance of the umbrella ribs.

[0017] Specifically, a long wire 13 that attracts each other is connected between the adjacent ends of the inner main rib 6 and the tail rib 8. When the inner main rib 6 is deployed, the middle main rib 7 and the tail rib 8 are simultaneously deployed by the traction of the long wire 13. The wire structure plays a role of additional support and reinforcement under strong winds, further improving the wind resistance performance of the umbrella ribs.

[0018] The operating principle and usage procedure of the present invention are as follows. When using the present invention, by pushing the lower lock 4 upward, the umbrella rib frame 1 can be opened. One end of the support rib 5 is pivotally attached to the lower lock 4, and the other end is connected to the central part of the inner main rib 6. When the lower lock 4 is pushed upward, the support rib 5 plays a role of supporting the inner main rib 6 and promotes the deployment of the inner main rib 6. Between the adjacent ends of the receiving bone 5 and the middle main bone 7, and the inner main bone 6 and the tail bone 8, short connecting lines 12 and long connecting lines 13 that attract each other are connected. When the receiving bone 5 and the inner main bone 6 are deployed, the middle main bone 7 and the tail bone 8 are deployed together due to the attraction of the short connecting lines 12 and the long connecting lines 13. A tension spring 14 is attached between the adjacent ends of the receiving bone 5 and the inner main bone 6 to maintain tension when the umbrella is opened, avoiding loosening and deformation of the framework. The umbrella rib frame 1 is manufactured by adopting a reinforcing material of glass fiber or carbon fiber. The middle main bone 7 and the tail bone 8 have a unique flat strip-shaped design, which provides better wind resistance performance in strong winds due to this shape. As shown in Figure 8, when encountering strong winds, the support bone 5 effectively supports the inner main bone 6. The middle main bone 7 and the tail bone 8 have a unique flat strip-shaped design. Even if they are bent backward by strong winds, due to their excellent flexibility, the umbrella ribs will finally return to their original shape and no deformation or damage will occur. The line structure plays a role of additional support and reinforcement under strong winds, further improving the wind resistance performance of the umbrella ribs. Such a comprehensive design not only greatly improves the wind resistance performance and stability of the umbrella ribs, but also improves the durability of the umbrella, making it less likely to be damaged even under strong winds.

[0019] The present invention can be applied to manual and automatic umbrellas during use.

[0020] Finally, it should be noted that the above content is only one of the optimal embodiments of the present invention and does not limit the present invention. Based on the foregoing embodiments, the present invention has been described in detail. However, those skilled in the art can make improvements to these embodiments or replace some technical elements with equivalent ones, and any changes, equivalent replacements, improvements, etc. made within the spirit and principle scope of the present invention shall be included in the protection scope of the present invention.
