Abstract:
A wind-resistant umbrella comprising:an elongated main support pole;a tubular secondary pole slidably translatable over said main support pole;a hub having a periphery and connected at one end thereof to said secondary pole and supportively engaged against a support member on said main support pole whereby, when said main support pole is upright, said secondary pole and said hub are supported on said main support pole by said support member;a plurality of vanes each having a central end, an outer end and trailing and leading longitudinal edges, said outer end being wider than said central end;each said central end pivotally connected in evenly spaced relation to and around substantially the entire said hub periphery;a vane carrier having a periphery and mounted for sliding translation over said secondary pole;a plurality of rigid or semi-rigid vane support rods each having a central end thereof pivotally connected in evenly spaced relation to and around substantially the entire said vane carrier periphery;an outer end of each said vane support rod pivotally connected along a mid point of said trailing longitudinal edge of each corresponding said vane;a clip attached adjacent each said vane outer end;an elongated substantially non-elastic cord extending circumferentially around and connected to each said clip;said leading longitudinal edge of each said vane remaining free and overlapping said trailing longitudinal edge of the next adjacent said vane, whereby a portion of each said vane may lift free of the next adjacent said vane in a wind to permit venting of said umbrella.
