Abstract
Description
Technical Field
[0001] The present invention relates to an umbrella, particularly a folding umbrella rib that is difficult to turn inside out.
Background Art
[0002] Prior Art As shown in FIGS. 1 and 2, the umbrella rib of a conventional folding umbrella has an inner main rib 1', an inner support rib 2', a middle main rib 3', an interlocking rib 4', an outer main rib 5', and a tension rib 6'. The interlocking rib 4' generally uses a spring wire (elastic structure) that is prone to deformation. When the folding umbrella is deployed and exposed to wind, the interlocking rib 4' is deformed by the force applied to the middle main rib 3'. Therefore, when the folding umbrella is exposed to strong wind, the interlocking rib 4' is strongly deformed, the middle main rib 3' is turned inside out, and the problem of the umbrella turning inside out (the umbrella flipping over) occurs. In view of the above problems, there is a need for a folding umbrella rib that is difficult to turn inside out and can prevent the interlocking rib from being strongly deformed and the umbrella from turning inside out.
Summary of the Invention
Problems to be Solved by the Invention
[0003] The object of the present invention is to provide a folding umbrella rib that is difficult to turn inside out and can prevent the interlocking rib from being strongly deformed and the umbrella from turning inside out.
Means for Solving the Problems
[0004] To achieve the above objective, the folding umbrella frame of this invention, which is resistant to turning inside out, has an inner main rib, an inner support rib, a central main rib, a connecting rib, an outer main rib, and a tension rib. The outer end of the inner support rib is pivotally connected to the middle part of the inner main rib. The vicinity of the inner end of the central main rib is pivotally connected to the outer end of the inner main rib. The vicinity of the inner end of the outer main rib is pivotally connected to the outer end of the central main rib. The inner end of the tension rib is pivotally connected to the vicinity of the inner end of the inner main rib. The outer end of the tension rib is pivotally connected to the inner end of the outer main rib. The connecting rib has a first connecting support rib and a second connecting support rib. Both the first and second connecting support ribs are rigid structures. The inner end of the first connecting support rib is pivotally connected to the vicinity of the outer end of the inner support rib. The inner end of the second connecting support rib is pivotally connected to the outer end of the first connecting support rib. The outer end of the second connecting support rib is movably connected to the inner end of the central main rib.
[0005] A guide groove is formed in the main internal bone, and a limit rod is placed in the guide groove. The first and second interlocking vertebrae pass through the guide groove. The second interlocking vertebra passes through the gap between the limit rod and the main internal bone.
[0006] The length of the second interlocking vertebra is longer than the length of the first interlocking vertebra.
[0007] The second interlocking rib has a hook portion for hooking onto the limit rod. When the inverting-resistant folding umbrella rib is unfolded, the hook portion of the second interlocking rib hooks onto the limit rod. When the inverting-resistant folding umbrella rib is folded, the hook portion of the second interlocking rib detaches from the limit rod. A hooking groove for hooking onto the limit rod is formed on the inside of the hook portion. An inclined guide surface for passing the limit rod is formed on the outside of the hook portion.
[0008] The outer end of the second interlocking stent is rotatably and movably connected to the inner end of the main stent.
[0009] An elongated hole is provided at the outer end of the second interlocking support bone. A connecting shaft is provided at the inner end of the central main bone. The connecting shaft passes through the elongated hole and is connected to the elongated hole in a rotatable and movable manner.
[0010] The anterior part of the second interlocking tributary is curved. [Effects of the Invention]
[0011] The interlocking ribs of this invention utilize rigid first and second interlocking support ribs. Compared to conventional elastic spring wire structures, the first and second interlocking support ribs of this invention are less susceptible to deformation under external forces. Therefore, when the umbrella ribs are deployed and subjected to strong winds, the first and second interlocking support ribs of the interlocking ribs are prevented from deforming severely, maintaining the load-bearing position of the central main ribs and preventing the interlocking ribs from deforming severely and turning the central main ribs inside out. This invention suppresses the turning of the umbrella inside out from the root, improves the wind resistance performance of folding umbrellas, and extends the lifespan of folding umbrellas.

[Figure 5] This is a partial cross-sectional view of the ribs of the folding umbrella designed to prevent it from turning inside out (in its unfolded state). [Figure 6] This is a schematic diagram of the structure of the second interlocking rib of the present invention. [Modes for carrying out the invention]
[0013] The present invention will be described in detail below with reference to examples.
[0014] As shown in Figures 3 to 6, the folding umbrella frame of this invention, which is resistant to turning inside out, has an inner main rib 1, an inner support rib 2, a central main rib 3, a connecting rib 4, an outer main rib 5, and a pull rib 6. The outer end of the inner support rib 2 is pivotally connected to the middle of the inner main rib 1. The vicinity of the inner end of the central main rib 3 is pivotally connected to the outer end of the inner main rib 1. The vicinity of the inner end of the outer main rib 5 is pivotally connected to the outer end of the central main rib 3. The inner end of the pull rib 6 is pivotally connected to the vicinity of the inner end of the inner main rib 1. The outer end of the pull rib 6 is pivotally connected to the inner end of the outer main rib 5. The connecting rib 4 has a first connecting support rib 41 and a second connecting support rib 42. Both the first connecting support rib 41 and the second connecting support rib 42 are rigid structures. The inner end of the first connecting support rib 41 is pivotally connected to the vicinity of the outer end of the inner support rib 2. The inner end of the second interlocking bone 42 is pivotally connected to the outer end of the first interlocking bone 41. The outer end of the second interlocking bone 42 is movably connected to the inner end of the central main bone 3 so that the central main bone 3 can rotate normally.
[0015] The interlocking ribs 4 of this invention use rigid first interlocking support ribs 41 and second interlocking support ribs 42. Compared to conventional elastic spring wire structures, the first interlocking support ribs 41 and second interlocking support ribs 4 of this invention are less prone to deformation under external forces. Therefore, when the umbrella ribs are deployed and subjected to strong winds, the first interlocking support ribs 41 and second interlocking support ribs 4 do not deform severely, maintaining the load-bearing position of the central main rib 3 and preventing the interlocking ribs 4 from deforming severely and causing the central main rib 3 to turn inside out. This invention suppresses the turning of the umbrella inside out from the root, improves the wind resistance performance of the folding umbrella, and extends the lifespan of the folding umbrella.
[0016] In this embodiment of the present invention, a guide groove 11 is formed in the inner main rib 1, and a limit rod 12 is positioned in the guide groove 11. The first interlocking rib 41 and the second interlocking rib 42 pass through the guide groove 11. The second interlocking rib 42 passes through the gap between the limit rod 12 and the inner main rib 1. As a result, the guide groove 11 restricts the position of the first interlocking rib 41 and the second interlocking rib 42, ensuring the stability of their movement. The length of the second interlocking rib 42 is longer than the length of the first interlocking rib 41. As a result, the size of the folding umbrella ribs of this invention, which are less likely to turn inside out when folded, is reduced, the overall structure becomes more compact, and the folding umbrella is easier to store.
[0017] In this embodiment of the present invention, the second interlocking rib 42 has a hook portion 421 for hooking onto the limit rod 12. When the inverting-resistant folding umbrella ribs of this invention are deployed, the hook portion 421 of the second interlocking rib 42 hooks onto the limit rod 12. In this case, the combination of the hook portion 421 and the limit rod 12 locks the structure and restricts the position of the inner main rib 1 and the interlocking rib 4 (in this case, the inner main rib 1 and the interlocking rib 4 become a rigid structure). Therefore, the structural stability after the inverting-resistant folding umbrella ribs of this invention are deployed is improved, the wind resistance is improved, and the umbrella can be prevented from turning inside out. When the inverting-resistant folding umbrella ribs of this invention are folded, the hook portion 421 of the second interlocking rib 42 detaches from the limit rod 12. Therefore, the inverting-resistant folding umbrella ribs of this invention can be folded and stored normally. The hook portion 421 is located in the middle of the second interlocking rib 42. A hook groove 4211 for hooking the limit rod 12 is formed on the inside of the hook portion 421. An inclined guide surface 4212 for passing the limit rod 12 is formed on the outside of the hook portion 421. The inclined guide surface 4212 allows the limit rod 12 to smoothly pass outside the hook portion 421 and be inserted into the hook groove 4211 on the inside of the hook portion 421 when unfolding the folding umbrella ribs of this invention, which are less likely to turn inside out. Also, an elongated hole 422 is provided at the outer end of the second interlocking support rib 42. A connecting shaft 31 is provided at the inner end of the central main rib 3. The connecting shaft 31 passes through the elongated hole 422 and is rotatably and movably connected to the elongated hole 422. As a result, the outer end of the second interlocking support rib 42 is rotatably and movably connected to the inner end of the central main rib 3. This allows the limit rod 12 to be inserted into and removed from the hook groove 4211 of the hook portion 421, enabling the folding umbrella ribs of this invention, which are less likely to turn inside out, to be opened and closed properly.
[0018] In this embodiment of the present invention, the anterior portion of the second interlocking vertebra 42 is curved. This allows the anterior portion of the second interlocking vertebra 42 to avoid the anterior end of the medial main vertebra 1, and enables the central main vertebra 3 to rotate normally.
[0019] In an embodiment of the present invention, a curved portion 423 is provided in the middle section of the second interlocking support bone 42. According to the curved portion 423, contact between the inner main bone 1 and other components can be avoided.
[0020] In an embodiment of the present invention, a guide bush 7 is provided in the middle section of the middle main bone 3. The pull bone 6 passes through the guide bush 7. Thereby, the position of the pull bone 6 can be restricted by the guide bush 7.
[0021] The present invention is not limited to the above embodiments and drawings, and any changes or improvements made by those skilled in the art are all included in the present invention.
