    • The umbrella has a central rod 11 with multiple sections 111,112,113, and utilises a variable dynamic process including the umbrella's skeleton mechanism 1, spring 2, locating device 3, shuttle arrow 4, control mechanism 5, handle 6, change-over device and pulling rig 7. Within the middle rod 11 of the umbrella's skeleton, the ends of a pulling rope 74 respectively reach the lower nest 14 and shuttle arrow 4. The control mechanism is manipulated by pressing button 61 to release the umbrella's skeleton for closing and folding under the reserve energy of the spring. In coordination with both pulling ropes 71,74, each section of skeleton is movable in tracks to extend and, in use, cause upward movement of the lower next section to open the umbrella. Rope 71 acts to draw the upper nest 13 upwards. The locating device 3 fastens the central rod at a fixed position with hook 30 engaged in hole 117 to resist against wind. The locating device is also operable to release the traction force between sections of the umbrella skeleton under the firm control of shuttle arrow. The spring 18 between branch skeletons is to close the umbrella and to change position to return to the original condition.
