ABSTRACT:
An improved opening structure of an unfolded umbrella includes a shaft with an upper mounting ring, a runner around the shaft, a frame having many ribs connected with the upper mounting ring and the runner, a button mounted on the shaft to engage with the runner for closing the umbrella. A rod is provided in the shaft at a lower position, an aperture is formed on the shaft with a wheel, and an elastic rope having one end connected with the rod and the other end extending upward to pass by the wheel, and to connect with the runner. When the umbrella is closed, the elastic rope is stretched that obtains a recovering force to open the umbrella quickly and automatically when the runner is unlocked.
