[0002] Umbrellas are essential tools for protecting against rain and sun when going out. Considering the umbrella's resistance to wind and rain, robust umbrella ribs are necessary. Current windproof umbrellas, to prevent the canopy from turning outwards, either thicken the rib structure, add reinforcing supports to the ribs, or use double-layered canopy and main / secondary rib structures. These designs not only increase costs but also appear bulky, sacrificing portability and aesthetics. These problems are particularly pronounced in situations requiring lightweight and compact umbrellas, such as outdoor travel and daily commutes. Therefore, developing an umbrella rib structure that maintains stability while achieving lightweight and compact design is crucial. Utility Model Content

[0027] like Figure 1 and Figure 2 As shown, a lightweight and miniaturized umbrella rib structure includes a support pole assembly 1, an upper nest 2, a lower nest 3, and multiple umbrella support rib assemblies 4. The upper nest 2 is fixed to the top of the support pole assembly 1, and the lower nest 3 is fitted onto the support pole assembly 1 and slides up and down relative to it. To reduce the overall weight, the upper nest 2 has an upper nest cutout 201, and the lower nest 3 also has a lower nest cutout 301, reducing material usage and effectively reducing the weight of the umbrella rib structure, making it easier for the user to hold. An umbrella tip 14 is provided at the bottom of the support pole assembly 1 for easy gripping by the user.

[0028] like Figures 2 to 5 As shown, the umbrella support assembly 4 includes a first umbrella support 41, a second umbrella support 42, a second umbrella support return line 43, and a closing spring 44. The first end of the second umbrella support 42 is rotatably connected to the lower nest 3, and its second end is provided with an offset joint 45.

The offset joint 45 has a receiving groove 451. When the umbrella is closed, the first umbrella support 41, the umbrella support return line, and the closing spring 44 are housed in the receiving groove 451 to reduce the volume after folding. The umbrella rib structure of this application, through the accommodating groove 451 structure design of the offset joint 45, achieves effective storage of components when the umbrella is closed, greatly reducing the volume of the umbrella rib after storage and improving portability; and the tight connection between the components ensures stability during the opening and closing process; the combined structure of the umbrella closing spring 44 and the return line enhances the support strength of the umbrella rib, combining aesthetics and safety, and improving the stability and durability of the umbrella during use.

[0029] In the specific implementation process of this embodiment, please refer to... Figure 2 and Figure 4 The umbrella rib assembly 4 also includes a third umbrella rib 46, a fourth umbrella rib 47, and a fourth umbrella rib return line 48. The first end of the third umbrella rib 46 is rotatably connected to the second end of the first umbrella rib 41, and the second end of the third umbrella rib 46 is rotatably connected to the first end of the fourth umbrella rib 47. A pivot joint 49 is provided in the middle section of the third umbrella rib 46, and the fourth umbrella rib return line 48 passes through the pivot joint 49. The two ends of the fourth umbrella rib return line 48 are respectively connected to the second end of the first umbrella rib 41 and the first end of the fourth umbrella rib 47. The structure of the pivot joint 49 allows for a reduction in angle when the umbrella is closed, thus reducing its volume. The connection structure of the third umbrella rib 46, the fourth umbrella rib 47, and the fourth umbrella rib return line 48 also provides stable support, ensuring the support strength and stability of the umbrella ribs, enabling the umbrella to better resist external forces such as wind during use.

[0030] In the specific implementation process of this embodiment, please refer to... Figure 3 The upper nest 2 has multiple first rotating slots 21, the same number as the multiple umbrella rib assemblies 4. The first ends of the multiple first umbrella ribs 41 are rotatably connected to the multiple first rotating slots 21 one by one. The upper nest 2 is also provided with a first locking ring 22 connecting the multiple umbrella rib assemblies 4. The lower nest 3 has multiple second rotating slots 31, the same number as the multiple umbrella rib assemblies 4. The first ends of the multiple second umbrella ribs 42 are rotatably connected to the multiple second rotating slots 31 one by one. The lower nest 3 is also provided with a second locking ring 32 connecting the multiple umbrella rib assemblies 4. This design not only achieves lightweighting but also ensures the stability of the connection between each umbrella rib assembly 4 and the upper and lower nests 3.

[0031] In the specific implementation process of this embodiment, please refer to... Figure 2 The support pole assembly 1 includes an inner tube 11, a middle tube 12, and an outer tube 13; the middle tube 12 is telescopically connected to the outer tube 13, and the inner tube 11 is telescopically connected to the middle tube 12; the upper nest 2 is fixedly connected to the top of the inner tube 11. The three-section telescopic design further enhances the portability of the umbrella, and the length of the support pole can be adjusted according to actual usage needs.

[0032] In the specific implementation process of this embodiment, please refer to... Figure 3The inner tube 11 is equipped with a positioning spring 111, and the lower nest 3 has a positioning slot 33 that engages with the positioning spring 111. During the opening process, when the lower nest 3 slides to the position of the positioning spring 111, the positioning spring 111 can engage with the positioning slot 33, thereby fixing the position of the lower nest 3 and ensuring the stability of the umbrella rib structure when open. At the same time, the lower nest 3 is also equipped with an elastic pressing member 34, which is used to drive the positioning spring 111 out of the positioning slot 33, thereby unlocking the lower nest 3 and allowing it to slide downwards to close the umbrella.

[0033] In this embodiment, a first elastic locking assembly is provided between the inner tube 11 and the middle tube 12. This first elastic locking assembly includes a first positioning block and an elastic positioning element, used to lock the telescopic positions of the inner tube 11 and the middle tube 12, maintaining the umbrella in an open or closed state. A second elastic locking assembly is provided between the middle tube 12 and the outer tube 13. This second elastic locking assembly includes a second positioning block, a positioning ball, and a positioning spring, used to lock the telescopic positions of the inner tube 11 and the middle tube 12, maintaining the umbrella in an open or closed state. These locking assemblies ensure the stability of the support rod after telescopic movement, preventing accidental retraction during use.

[0034] It should also be noted that, without conflict, the embodiments of this utility model and the features therein can be combined with each other to obtain new embodiments.
