BACKGROUND OF THE INVENTION

As shown in FIG. 1, it shows a conventional three-folded umbrella including a first rib (1), a second rib (2), and a tail rib (3). A main branch rib (11) has its outer end connect with middle portion of the first rib (1). A first supplementary rib (12) is provided between the inner end of the second rib (2) and outer portion of the main branch rib (11). Due to the structure of the first supplementary rib (12), the main branch rib (11) must be provided with its U-shape open end downward for receiving the supplementary rib (12) when the frame is closed. It is to be found that the downward opening of the main branch rib (11) will hurt people's hand or fingers when he is pushing a runner upward to open the umbrella.
