In an exemplary embodiment, a wind resistant parasol is disclosed which includes a pole and a rib mechanism attached to the pole. The rib mechanism includes a plurality of upper ribs configured to support an upper canopy, a plurality of lower ribs configured to support a lower canopy, and a rib connector connecting the plurality of upper ribs and the plurality of lower ribs together to form a closed loop. When the parasol is open, the upper canopy has a substantially flat profile and the lower canopy has a curved profile formed by the respective plurality of upper ribs and the plurality of lower ribs, wherein the lower canopy is configured to guide air pressure in a downward direction causing the parasol to stabilize.

An umbrella has a plurality of ribs attached to a runner by main struts. The umbrella has an anti-inversion mechanism formed of a plurality of anti-inversion struts. Each anti-inversion strut is pivotally coupled to one respective main strut and is pivotally connected to a floating joint member that is freely movable along a length of one respective rib. The anti-inversion mechanism also includes a stop that is fixedly attached to the rib and restricts the degree of travel of the floating joint member along the rib and is positioned to prevent the respective rib from inverting in response to an applied force.

A reverse folding umbrella folds away from a user of the umbrella, thus reducing the likelihood that rain or other water on the primary fabric of the umbrella will fall onto the user while the umbrella is being folded and while the umbrella is in the closed position.

The formation of dynamic, micro-climate groups consisting of passive and active weather collecting devices is provided. Such devices may collect weather information in real-time. The collected information may be distributed weather information and or forecasts to individuals in a particular geographical area or to other subscribers.

An automatic non-collapsible umbrella includes a handle, a control mechanism, a center post, a detent mechanism, a runner assembly, and a skeleton. A cylindrical main seat of the control mechanism includes a spring biased open button for opening the umbrella, and a spring biased collapse button adjacent to the collapse button for closing the umbrella.

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.
