Hand-push rotating umbrella

Abstract

A hand-push rotating umbrella comprises extension springs at one side of the supporting ribs where an upward acting force can be produced by means of the pretension force of the extension spring when the moveable runner is pushed up so that the moveable runner and upper rib supporting rods would not fall down affected by gravity, thus a stable umbrella closing state able to be achieved without providing the engagement structure and solving the problems of the existing reversely-folded umbrella produced by only able to stably close the umbrella by using the engagement structure. Moreover, through the collocation application of the upper runner and moveable runner in the present invention, the umbrella canopy would rotate to offset the impact force caused by the wind resistance or collision in the case of strong wind or umbrella rib collision with some foreign object or person, thus able to avoid stabbing and hurting other people and improve the umbrella use safety.
