The top bone 21 is made of plastic having elasticity. Materials, reinforced plastics (eg, FRP), metals, composites and suitable munitions It can be formed from other suitable materials having properties. Shape and material of top bone 21 The fee is not limited in the present invention.       [0012]   As shown in FIG. 2, the top bone 21 is straightened when the umbrella is closed and folded. From an upright or upright state, open the umbrella and radiate like a lotus-shaped array When bowed or deployed, it preserves elastic energy. This allows the top Bone 21 may be a self-closing umbrella "restoring spring" or a self-closing umbrella for automatically closing the umbrella. Functions as a "closing spring". In the present embodiment, the top bone 21 Each is formed by a leaf spring, an elastic spring rod or a plate.       [0013]   As shown in FIGS. 2 to 4, the bone assembly 2 is spread out like a lotus-shaped arrangement. Are a number of inner adapters rotatably mounted on the upper notch 20 on the shaft 1. And a cover 21a. Each of the inner adapters 21a has a pair of tops. The bones 21 are connected so as to branch radially. Connect to inner adapter 21a The paired top bones 21 are bifurcated on the outside, and two adjacent bones are mutually separated. It is connected to each of the joint members 22. When the umbrella is opened, the umbrella As can be seen from the top or bottom side, the top bone 21 is The umbrella is curved and expanded radially so as to form a lotus flower shape around the When the is open, elastic energy is stored.       [0014]   In other words, each of the joint members 22 is connected to the pair of top bones 21. The inner end 221 is formed. A pair of top bones 2 connected to the inner end 221 1 is bifurcated inside and is rotatably attached to the upper notch 20 on the shaft 1.
