Jenan Kazim, an aeronautical engineer in the United Kingdom, invented this Inverted umbrella. The original purpose of inventing this umbrella was to prevent rainwater from reaching the floor.
The working principle of the double layer reverse umbrella is that when the umbrella is closed (the umbrella runner moves downward), the outer layer shrinks inward and the inner layer outwards. The working principle of the single-layer reverse folding umbrella is to reduce the cross section of the tail rib. Keep 3 ribs, and don't use the fourth ribs. Because the tips of the fourth section of ribs will go down (close to the handle), and the third section of ribs will go up (close to End Top). And when the reverse folding umbrella is closed, the canopy of the third section of ribs will be turned over, and the umbrella can be wrapped by the inner canopy.
Inverted Umbrella has automatic and manual systems. The handle of the automatic system has buttons beside it, and the manual system can push the runner to open and close.
