Integrally formed umbrella framework

Abstract

An integrally formed umbrella framework comprises an upper nest, a lower nest, a plurality of long bones and the same number of supporting bones. A plurality of connecting sections surround and are integrally connected with a periphery of the upper nest at equal intervals, and each connecting section is integrally connected with the upper end of a long bone. A plurality of connecting sections surround and are integrally connected with a periphery of the lower nest at equal intervals, and each connecting section is integrally connected with the lower end of a supporting bone. Each long bone has a connecting section disposed at the middle part thereof and integrally connected with the upper end of the supporting bone. The upper nest, the lower nest, the plurality of long bones, the same number of supporting bones, and each of the connecting sections are integrally formed of a same material.

What is claimed is: 
     
         1 . An integrally formed umbrella framework, comprising a middle rod, an upper nest, a lower nest, a plurality of long bones and the same number of supporting bones, the upper nest being fixed to a top end of the middle rod, and the lower nest being fitted over the middle rod and being capable of sliding up and down, wherein:
 an axial hole is disposed at the bottom of the upper nest to receive the middle rod, a plurality of connecting sections surrounding a periphery of the upper nest at equal intervals are integrally connected with the upper nest, each of the connecting sections is integrally connected with the upper end of a long bone, and each of the connecting sections is freely bendable;   an axial hole is disposed at an axis end of the lower nest to receive the middle rod, a plurality of connecting sections surrounding a periphery of the lower nest at equal intervals are integrally connected with the lower nest, each of the connecting sections is integrally connected with the lower end of a supporting bone, and each of the connecting sections is freely bendable;   each of the plurality of long bones has a connecting section disposed at the middle part thereof, the middle part of the long bone is integrally connected with the upper end of the supporting bone via the connecting section, and the connecting section is freely bendable; and   the upper end of each of the plurality of supporting bones is integrally connected with the middle part of the long bone via a connecting section, and the lower end of each of the supporting bones is integrally connected with the lower nest via a connecting section.   
     
     
         2 . The integrally formed umbrella framework of  claim 1 , wherein the upper nest, the lower nest, the plurality of long bones, the same number of supporting bones, and each of the connecting sections are integrally formed of a same material.
