New description: [New technical field] This creation is about an umbilical structure and umbrella, especially for a part of the umbilical foldable rib structure and umbrella. [Prior Art] Umbrellas are generally used for sheltering rain or sunshade, while others are mainly used for decoration. In the past, when people went out to parachute, they often feared that they would encounter strong winds. The large wind resistance caused by umbrellas would easily make people difficult to hold. The umbrella itself often had eversion and flowering, which made the users feel embarrassed and wrong. In response to the above problems, the early reinforcement of the rib structure allows the ribs to resist large external forces without eversion. For related information, for example, refer to TW592062. However, this simple design of the sacral structure is designed to overcome the characteristics of the county side needle (four) umbrella material production line, so when the user uses the umbrella, even if the umbrella is not easy to be everted, the wind resistance will continue Passed to the user's wrist with a magical instrument, after a period of time, it is expected to cause discomfort to the user's hand. In addition, there is also a windproof umbrella as disclosed in the TWM291228 'TW474135 patent, which forms a plurality of exhaust holes on the umbrella Φ to provide a resistance to the air zone. This 4', which reduces the wind resistance, is basically contrary to the required cover of the umbrella. Therefore, it is necessary to consider how to avoid the inflow of rainwater from the opening. In recent years, there have been problems such as the application of the flow mechanics principle of the umbrellas disclosed in TW M368329, TW1335805, and US7992581 patents. The wind resistance is reduced by a special non-equal design, and the problem of easy eversion of the umbrella is improved from the source. Due to the special contour of the umbrella of such an umbrella, it may cause inconvenience in storage. For example, in Figure 4 of the patent of Ding Lai 368,329, the umbrella has a longer section in the umbrella surface when it is in the state of 3 M428691 It has obvious vertical sag compared to other parts. In view of this, how to improve the storage performance while reducing wind resistance is subject to the realization of the industry. [New content] The main purpose of this creation is to provide an umbilical structure and an umbrella with reduced wind resistance and easy folding. The rib structure provided for the above purpose is provided for the long main pole of an umbrella.
