Abstract
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.
