[0047] Example 1
[0048] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, this embodiment provides an umbrella frame structure, including an umbrella rib 1, an upper umbrella nest 131, a lower umbrella nest 132, and an umbrella handle 8. The umbrella rib 1 includes several umbrella tubes connected in sequence. The upper umbrella nest 131 is located at the upper end of the outermost umbrella tube 13. The lower umbrella nest 132 is slidably mounted on the outermost umbrella tube 13. The lower end of the innermost umbrella tube 11 is connected to the umbrella handle 8. A cord winder 2 is provided in the umbrella handle 8, and a pull cord 3 is provided between the cord winder 2 and the lower umbrella nest 132. A sliding cord is provided in the innermost umbrella tube 11. Block 112, slider 112 is provided with at least one movable pulley 1121, one end of slider pull rope 4 is wound around rope winder 2, the other end passes through movable pulley 1121 and is connected to umbrella handle 8; one end of middle tube pull rope 5 is connected to slider 112, the other end is connected to middle umbrella tube 12; one end of outer tube pull rope 7 is connected to innermost umbrella tube 11, the other end is connected to outermost umbrella tube 13; one end of lower nest pull rope is connected to innermost umbrella tube 11, the other end passes through upper nest 131 and is connected to lower nest 132.
[0049] Specifically, the upper umbrella nest 131 and the lower umbrella nest 132 are used to fix and connect the umbrella slats (not shown in the figure) that support the umbrella canopy. When the lower umbrella nest 132 moves down away from the upper umbrella nest 131, the umbrella slats are retracted, thus closing the umbrella canopy; conversely, when the lower umbrella nest 132 moves up towards the upper umbrella nest 131, the umbrella slats are unfolded, thus opening the umbrella canopy. The middle umbrella tube 12 can be one or more sections. The slider pull rope 4 and the umbrella closing pull rope 3 are independently provided pull ropes. The rope winder 2 has the function of winding and unwinding the slider pull rope 4 and the umbrella closing pull rope 3.
[0050] When closing the umbrella, the rope winder 2 rotates clockwise to wind up the umbrella closing rope 3, thereby moving the lower umbrella stalk 132 downwards to close the umbrella canopy. Simultaneously, the opening rope 6 is driven by the lower umbrella stalk pulley 1321 located on the lower umbrella stalk 132, pulling and engaging adjacent umbrella tubes. At the same time, the outer tube rope 7 engages the middle umbrella tube 12 with the innermost umbrella tube 11, achieving the retraction and closing of the umbrella rib 1, thus completing the umbrella closing operation. Simultaneously, the middle tube rope 5 pulls the slider 112 upwards toward the upper umbrella stalk 131.
[0051] Similarly, when the umbrella is opened, the cord winder 2 rotates counterclockwise, the slider cord 4 is wound up, the slider 112 moves down, and the middle tube cord 5 and the outer tube cord 7 are pulled, so that the umbrella tubes of the umbrella rib 1 extend in sequence. At the same time, the umbrella opening cord 6 causes the umbrella under-nest 132 to move upward, so that the umbrella canopy can be unfolded.
[0052] In this way, the opening or closing of the umbrella can be completed simply by operating the rope winder 2, and the umbrella rib 1 can be extended and retracted simultaneously when the umbrella canopy is opened and closed, making it more convenient and labor-saving to use and greatly improving the user experience.
[0053] In this embodiment, two movable pulleys 1121 are provided, and a fixed pulley 113 is provided on the innermost umbrella tube 11 of the umbrella rib structure. One end of the slider rope 4 is fixedly installed along one movable pulley 1121, the fixed pulley 113, and the other movable pulley 1121 to the umbrella handle 8. In this way, the movable pulley 1121 can share part of the load, reducing the force acting on the slider 112. The slider 112 only needs to move a certain distance for the umbrella canopy 132 to achieve a large displacement. In this embodiment, the moving distance of the slider 112 is only 1 / 3 of the moving distance of the umbrella canopy 132. For example, to move the umbrella canopy 132 upward by 30cm, it is only necessary to pull the slider 112 downward by 10cm, which improves the convenience of using the umbrella rib structure and makes operation more labor-saving.
[0054] In this embodiment, the innermost umbrella tube 11 has an inner tube pulley 114 on its tube plug 9 for winding the middle tube pull rope 5, and the middle umbrella tube 12 has a middle tube pulley 121 on its tube plug 9 for winding the outer tube pull rope 7. The upper umbrella nest 131 has an upper nest pulley 134, and the lower umbrella nest 132 has a lower nest pulley 1321. The other end of the lower nest pull rope is fixedly mounted along the upper nest pulley 134, the lower nest pulley 1321, and back to the upper nest pulley 134. This effectively reduces wear on the pull rope after prolonged use and makes its movement smoother. Simultaneously, it ensures stable operation of the pull rope along a predetermined path, guaranteeing stability during use.
[0055] In this embodiment, an elastic element 1322 is provided between the umbrella retractor cord 3 and the umbrella undergrowth 132. The elastic element 1322 can be a spring or an elastic band. Since there are certain differences in the tension of the retractor cords, the elastic element 1322 can adaptively adjust the tension of the retractor cords and compensate for changes in the length of the retractor cords, ensuring that each retractor cord is subjected to uniform force and maintaining the overall balance and coordination.
[0056] Example 2
[0057] Please refer to Figure 1 and Figure 2 As shown, this embodiment includes the description of the umbrella rib structure in Embodiment 1, and a first pulley 133 is provided on the outermost umbrella tube 13, and a second pulley 122 is provided on the middle umbrella tube 12 on the same side as the first pulley 133. The second pulley 122 is provided through the tube plug 9 of the middle umbrella tube 12; one end of the umbrella pulling rope 3 is provided along the inner hole of the umbrella rib 1, the second pulley 122, the first pulley 133 to the umbrella lower nest 132.
[0058] When closing the umbrella, the cord winder 2 rotates clockwise to wind up the umbrella closing cord 3. The closing cord 3 moves the lower umbrella housing 132 downwards along the second pulley 122 and the first pulley 133 to close the umbrella canopy. At the same time, the lower umbrella housing pulley 1321 moves synchronously with the lower umbrella housing 132 to drive the opening cord 6, causing the innermost umbrella tube 11 to engage with the middle umbrella tube 12. Then, as the closing cord 3 continues to wind up, it engages the middle umbrella tube 12 with the outermost umbrella tube 13, thus achieving the retraction and closing of the umbrella rib 1 and completing the umbrella closing operation. Simultaneously, the middle tube cord 5 pulls the slider 112 upwards toward the upper umbrella housing 131.
[0059] The second pulley 122 and the first pulley 133 are used to wind the umbrella closing rope 3, limiting the movement trajectory of the umbrella closing rope 3, thereby preventing the umbrella closing rope 3 from getting tangled or worn, and improving the smoothness and durability of closing the umbrella.
[0060] Similarly, when the umbrella is opened, the cord winder 2 rotates counterclockwise, the slider cord 4 is wound up, the slider 112 moves down, and the middle tube cord 5 and the outer tube cord 7 are pulled, so that the umbrella tubes of the umbrella rib 1 extend in sequence. At the same time, the umbrella opening cord 6 causes the umbrella under-nest 132 to move upward, so that the umbrella canopy can be unfolded.
[0061] Example 3
[0062] Please refer to Figure 3 and Figure 4 As shown, this embodiment includes the description of the umbrella rib structure in Embodiment 1, and a first pulley 133 is provided on the outermost umbrella tube 13, and a third pulley 1311 is provided on the same side as the first pulley 133 on the umbrella upper nest 131; one end of the umbrella pulling rope 3 is provided along the inner hole of the umbrella middle rib 1, the third pulley 1311, the first pulley 133 to the umbrella lower nest 132.
[0063] When closing the umbrella, the rope winder 2 rotates clockwise to wind up the umbrella closing rope 3, causing the closing rope 3 to move downwards along the third pulley 1311 and the first pulley 133, thus closing the umbrella canopy. At this time, the lower canopy pulley 1321 moves synchronously with the lower canopy 132, driving the opening rope 6, which in turn engages the innermost umbrella tube 11 with the middle umbrella tube 12. Continuing to pull, the outermost umbrella tube 13 engages with the middle umbrella tube 12, achieving the retraction and closing of the umbrella rib 1, completing the umbrella closing operation. Simultaneously, the middle tube rope 5 pulls the slider 112 upwards toward the upper canopy 131.
[0064] The third pulley 1311 and the first pulley 133 are used for winding the umbrella pull rope 3. Guided by the third pulley 1311 and the first pulley 133, the movement trajectory of the umbrella pull rope 3 is limited, and friction is effectively reduced to ensure a smooth and stable umbrella closing process.
[0065] Similarly, when the umbrella is opened, the cord winder 2 rotates counterclockwise, the slider cord 4 is wound up, the slider 112 moves down, and the middle tube cord 5 and the outer tube cord 7 are pulled, so that the umbrella tubes of the umbrella rib 1 extend in sequence. At the same time, the umbrella opening cord 6 causes the umbrella under-nest 132 to move upward, so that the umbrella canopy can be unfolded.
[0066] Example 4
[0067] Please refer to Figure 5 and Figure 6 As shown, this embodiment includes the description of the umbrella rib structure in Embodiment 1, and a first pulley 133 is provided on the outermost umbrella tube 13; the umbrella pull cord 3 includes a first cord segment 31 and a second cord segment 32. The first cord segment 31 is provided between the cord winder 2 and the umbrella upper nest 131, one end of the second cord segment 32 is provided on the umbrella lower nest 132, and the other end of the second cord segment 32 passes around the first pulley 133 and is provided on the middle umbrella tube 12.
[0068] When closing the umbrella, the cord winder 2 rotates clockwise, winding the first cord segment 31. The outermost umbrella tube 13 is pulled by the first cord segment 31 and engages with the middle umbrella tube 12. At this time, the first pulley 133 moves synchronously with the outermost umbrella tube 13, driving the second cord segment 32 to pull the lower umbrella nest 132 towards the cord winder 2, completing the closing action of the umbrella surface. Simultaneously, the outer tube pull cord 7 drives the middle umbrella tube 12 to engage with the innermost umbrella tube 11. Furthermore, as the lower umbrella nest 132 moves towards the cord winder 2, the opening pull cord 6 simultaneously drives the innermost umbrella tube 11 to engage with the middle umbrella tube 12; this achieves the engagement and retraction of the umbrella rib 1, completing the umbrella closing operation. At the same time, the middle tube pull cord 5 pulls the slider 112 upwards towards the upper umbrella nest 131.
[0069] Similarly, when the umbrella is opened, the cord winder 2 rotates counterclockwise, the slider cord 4 is wound up, the slider 112 moves down, and the middle tube cord 5 and the outer tube cord 7 are pulled, so that the umbrella tubes of the umbrella rib 1 extend in sequence. At the same time, the umbrella opening cord 6 causes the umbrella under-nest 132 to move upward, so that the umbrella canopy can be unfolded.
