Automatic Umbrella / umbrella

Automatic Umbrella
Automatic Umbrella

Automatic Umbrella spreads when it is upward and closes when downward, which goes naturally with human behavior and solves the problem of having to use an umbrella with two hands.

There is a heavy ball inside the handle. When people hold the umbrella upward or downward, the ball hits the switches at the ends of the handle to open or close.
