 The present invention relates to a connection structure between an umbrella meat and a middle meat, and more particularly, in the case of a parasol, in particular a large parasol, to prevent the umbrella meat from being bent due to the influence of its own weight or wind, and to break the umbrella meat when the parasol is fallen. To prevent the structure of the umbrella to increase the stiffness of the umbrella meat, and to the structure of the combination of the intermediate meat.

In the case of a general parasol, the umbrella meat supporting the umbrella cloth is fixed radially on the upper part of the umbrella stand, and in order to support the umbrella meat, one end of the middle meat is fitted under the umbrella stand and the other end is mounted on the umbrella meat. When the parasol is unfolded, the middle flesh is supported to maintain the parasol shape while supporting the vicinity of the center portion of the umbrella in a state fixed to the umbrella stand.

Most umbrella umbrellas use fiber reinforced plastic (FRP). FRP has a high strength and light weight, so there is a disadvantage in that it is easy to bend due to lack of good material or rigidity as an umbrella for parasol. In the case of a parasol, its weight increases in proportion to its large volume, so when used for a long time, the umbrella is more curved and deformed than its original form. These deformations are aggravated by the wind, and in the case of strong winds, parasols can be greatly deformed and unusable. This problem becomes serious as the size of the parasol increases.

In order to improve this, the entire parasol rib is made of a metal pipe or a metal reinforcing material is inserted into the center and then coated with a plastic resin around the product. However, this is not only expensive but also has poor workability. In addition, due to the lack of elasticity, once deformed, it is difficult to return to its original form and the weight increases.
