An umbrella with a frame structure supported by a support structure. The frame structure has a support hub, a plurality of long ribs each comprising a first rib section and a second rib section releasably connected by a pivot rib coupler, wherein each long rib has an end releasably or fixedly coupled to an upper end of the support hub. The frame structure further having a plurality of short rib sections in the form of a plurality of third rib sections, each comprising a first end releasable coupled to the pivot rib coupler and a second end releasably or fixedly coupled to a lower end of the support hub, wherein each pivot rib coupler is configured to pivot the third rib section relative to the first and second rib sections that are releasably coupled to the pivot rib coupler.

An umbrella system is provided, including an elongated handle having an upper section, a canopy section disposed at the upper section of the handle, and a canopy operating mechanism connected the handle to the canopy section and configured to switch the umbrella system between an open mode and a closed mode. The canopy section includes an edge section formed with a plurality of blades, each of the plurality of blades being disposed to side-contact or partially overlap adjacent blades of the plurality of blades. The blades come into close contact with the adjacent blades to form an enclosure to seal the interior cavity such that raindrops, snowflakes, water, or other moisture on upper surfaces of the canopy section is sealed within the interior cavity to inhibit the raindrops, snowflakes, water, or other moisture from leaking out of the interior cavity, when the umbrella is in the closed mode.

A rapidly deployable structure comprising a first hub, a second hub, a plurality of legs and a rod connected to the first hub. The first hub includes a first plurality of recesses. The second hub includes a second plurality of recesses and an alignment guide. Each of the plurality of legs is connected to the first hub and the second hub. The rod connected is to the first hub and comprises a plurality of pins that are movable between an extended state and a retracted state. In the extended state, pins protrude from the rod. In a retracted state, the pins are retracted within the rod. The first hub is movable relative to the second hub between a first state in which the rod is disposed above the alignment guide in an axial direction defined by an opening in the alignment guide and a second state in which a portion of the rod comprising the plurality of pins is located below the alignment guide in the axial direction.
