An adjustable non-view obscuring umbrella having a canopy and a support structure. The support structure having a support post, a plurality of non-articulating umbrella ribs, and at least one articulating umbrella rib. An articulating umbrella rib having an upper rib member, a lower rib member, and an umbrella rib articulation mechanism. An umbrella rib articulation mechanism having an upper bracket and a rotation actuation member, wherein the rotation actuation member is rotationally coupled to the upper bracket

An umbrella frame comprising a shaft, a canopy frame with a plurality of ribs around the shaft, each rib being collapsible, wherein the canopy frame is deployable to a length RLT, and collapsible to a length CL, such that the ratio RLT:CL is improved over existing umbrellas.

An automatic inversely foldable umbrella includes a skeleton structure provided with a main shaft; an upper runner fixed to one end of the main shaft; a lower runner slidably disposed on the main shaft; a middle runner slidably disposed on the main shaft between the upper runner and the lower runner; plural skeleton linkages having a first rib, a second rib, and a foldable rib; plural linking members with one end pivotally disposed on the lower runner and the other end connected with the first rib; a resilient member disposed between the middle runner and the lower runner, and compressible due to the middle runner and the lower runner movement; a first canopy combined to the upper runner and a second canopy combined to the lower runner for covering the skeleton linkages; and a handle. Therefore, the folding and expanding operation of the umbrella are facilitated.

An umbrella includes a shaft, a cap connected to the shaft, a runner movable on the shaft, long and short ribs, a controller unit and rib-collapsing units. The runner includes recesses. Each of the long ribs includes upper, middle and lower sections. The short ribs connect the upper sections of the long ribs to the runner. The controller unit is operable to allow the long ribs to stretch and collapse. Each of the rib-collapsing units includes a cap magnet connected to the cap, a runner magnet inserted in a corresponding one of the recesses and two middle-section magnets. The first middle-section magnet is connected to the middle section of a corresponding one of the long ribs and adapted for attraction to the cap magnet. The second middle-section magnet is connected to the middle section of a corresponding one of the long ribs and adapted for attraction to the runner magnet.

The umbrella capable of being quickly assembled and disassembled comprises a column; a plurality of long rods; a plurality of short rods; an upper nest; a lower nest; a plurality of rod connectors; a plurality of connecting mechanisms. Each long rod has a first end which is detachably connected to the upper nest through one rod connector, and each short rod has a first end which is detachably connected to the lower nest through one rod connector and a second end which is detachably connected to the middle portion of the corresponding long rod through one connecting mechanism. The present invention is simple and reasonable in structure and easy to operate. During disassembling, it is only necessary to disassemble the elastic connecting pins from the connecting mechanisms, and the long rods and the short rods can be quickly disassembled from the nests without using any tool.
