Description

[Technical Field]

[0001] This invention relates to an umbrella, and more particularly to a wind-resistant umbrella rib, a multi-fold umbrella rib and an umbrella, in the field of everyday items. [Background technology]

[0002] An umbrella is a portable tool for sheltering from the sun or rain, and typically consists of a foldable handle, ribs (metal or plastic) and a covering made of waterproof or UV-resistant material (such as nylon, polyester, PVC, etc.).

[0003] When an umbrella is caught in a strong wind, the umbrella surface, along with the ribs (usually the two outermost ribs, shown in the figure as ribs 4 and 6), may flip from their normal position to the opposite direction, as shown in Figure 4, from position C to position D. At this point, the entire umbrella surface flips upward, making it impossible to use normally. In the umbrella design process, the limit of force that can be withstood in such a situation, commonly known as wind resistance, is an important indicator. Conventional umbrellas have limited wind resistance, and improving the wind resistance of umbrellas is a constant goal pursued in the umbrella industry. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the drawbacks of the limited wind resistance of umbrellas in the prior art mentioned above, the present invention provides an umbrella rib, multi-fold umbrella ribs, and umbrella with excellent wind resistance. The umbrella ribs have recesses at the ends, which, when used in combination with fixing points on other umbrella ribs, can increase the wind resistance of the entire umbrella rib. [Means for solving the problem]

[0005] The technical means used in this invention to solve the technical problem are as follows: a wind-resistant umbrella bone support, the umbrella bone support comprises a support body, one end of the support body is provided with a first connection hole for the first support bone, the other end of the support body is provided with a base connection hole for the first support bone, and the support body is provided with a recess.

[0006] The multi-fold umbrella rib comprises the first, second, third, fourth, and fifth support ribs and an umbrella rib connecting member as described above, wherein the third support rib is connected to the middle position of the second support rib, one end of the first support rib is connected to the third support rib, the other end of the first support rib is connected to one end of the umbrella rib connecting member, the other end of the umbrella rib connecting member is connected to one end of the fourth support rib, and the other end of the fourth support rib is connected to one end of the fifth support rib, and a fixed fixing point is provided on the second support rib corresponding to the position of the recess on the first support rib.

[0035] In this embodiment, the fourth support 4 and the elastic rod 5 are fastened together by a fixing ring 8, which can be made of a rubber band, a cable tie, or formed by bending the top of the fourth support 4.

[0036] In this embodiment, the elastic rod 5 may be formed by bending a wire. When the method of bending a wire is adopted, the first connecting hole 51 of the elastic rod and the second connecting hole 52 of the elastic rod may not be provided, but both ends of the wire may be bent to form hooks, and the hooks at both ends may be directly hooked onto the third connecting hole 23 of the second support rib and the first connecting hole 61 of the fifth support rib.

[0037] The present invention also claims an umbrella, which comprises the above-mentioned multi-fold ribs. Usually, a plurality of the above-mentioned multi-fold ribs are attached to the upper and lower parts of the umbrella handle, and the middle of the umbrella cloth and the top of the umbrella handle are fixed together, and the edge of the umbrella cloth and the second connecting hole 62 of the fifth support rib are aligned together, and preferably the middle position of the umbrella cloth and the first umbrella cloth fixing position 26 are aligned together.

[0038] In normal use, during the unfolding process of the umbrella, the first rib 1, the second rib 2 and the fifth rib 6 unfold under the influence of the third rib 3, and when the first rib 1 moves under the influence of the third rib 3 until the recess 14 on the first rib 1 engages with the fixed point (fixing rivet 14) on the second rib, the umbrella surface is fully unfolded.

[0039] When the umbrella surface is fully unfolded and the outer end of the fourth support rib 4 is turned outward, a diagonal force is generated at the inner end of the fourth support rib 4, causing it to turn upward. At this time, the recess 14 on the first support rib 1 engages with the fixed point on the second support rib 2, and the first support rib 1 stably pulls the inner end of the fourth support rib 4, thereby increasing the wind resistance of the entire umbrella.

[0040] In this device, a recess is provided at the end of the umbrella rib, which, when used in combination with the fixing points on the other ribs, can increase the wind resistance of the entire umbrella rib. When the umbrella is fully opened and the umbrella face is turned outward, the outer end of the fourth rib of the umbrella rib moves downward and the inner end of the fourth rib of the umbrella rib moves upward, at which point the recess on the first rib engages with the fixing point on the second rib, and the first rib stably pulls the inner end of the fourth rib, thereby increasing the wind resistance of the entire umbrella.
