Umbrella with rearward extending frame and canopy

Abstract

An umbrella includes a shank, a frame, and a canopy in covering relationship to the frame wherein the canopy includes a main section and a rearward extending section, and the frame includes a plurality of rearward extending first rib sections. The umbrella being open is adapted to provide a wider protection area to an object carried on the shoulder or towed by the hand against the rain. The umbrella frame is made of FRP so as to reduce weight significantly.

1 . An umbrella ( 1 ) comprising:
 a shank ( 10 );   a frame ( 20 ); and   a canopy ( 30 ) in covering relationship to the frame ( 20 );   wherein the canopy ( 30 ) comprises a main section ( 31 ) and a rearward extending section ( 32 ); and the frame ( 20 ) comprises a plurality of rearward extending first rib sections ( 40 ).   
   
   
       2 . The umbrella of  claim 1 , wherein the rearward extending section ( 32 ) is folded into three sections, the main section ( 31 ) is fixed in length, and the length of the rearward extending section ( 32 ) is about the same as that of the main section ( 31 ) when the umbrella ( 1 ) is closed. 
   
   
       3 . The umbrella ( 1 ) of  claim 1 , further comprising a hub ( 11 ) on the top end of the shank ( 10 ), a lower sleeve ( 13 ) slidably put on the shank ( 10 ), an upper runner ( 12 ) slidably put on the shank ( 10 ), a spring ( 14 ) put on the shank ( 10 ) being biased between the sleeve ( 13 ) and the runner ( 12 ), and wherein the frame ( 20 ) further comprises a front section ( 21 ) including a plurality of ribs ( 211 ) extending radially from the hub ( 11 ) and adapted to pivot about the hub ( 11 ) with a portion of the main section ( 31 ) in covering relationship thereto, a plurality of first fixed joints ( 212 ) disposed in the intermediate portions of the ribs ( 211 ), and a plurality of first stretchers ( 213 ) pivotably interconnecting the first fixed joints ( 212 ) and the runner ( 12 ); and a rear section ( 22 ) including a plurality of second rib sections ( 221 ) extending radially from the hub ( 11 ) and adapted to pivot about the hub ( 11 ) with the remaining portion of the main section ( 31 ) in covering relationship thereto, a plurality of second stretchers ( 223 ) extending radially from the runner ( 12 ) and adapted to pivot about the runner ( 12 ), a plurality of second fixed joints ( 222 ) disposed in the intermediate portions of the second stretchers ( 223 ), a plurality of pivotal joints ( 224 ) disposed in the open ends of the second stretchers ( 223 ) with the first rib sections ( 40 ) fixedly secured thereto, and a plurality of links ( 225 ) pivotably interconnecting the pivotal joints ( 224 ) and distal ends of the second rib sections ( 221 ) and being substantially parallel to the second stretchers ( 223 ) when the umbrella ( 1 ) is open. 
   
   
       4 . The umbrella ( 1 ) of  claim 3 , further comprising a plurality of first auxiliary stretchers ( 131 ) pivotably interconnected the sleeve ( 13 ) and predetermined points of the first stretchers ( 213 ), and a plurality of second auxiliary stretchers ( 132 ) pivotably interconnected the sleeve ( 13 ) and predetermined points of the second stretchers ( 223 ). 
   
   
       5 . The umbrella ( 1 ) of  claim 3 , wherein the ribs ( 211 ), the first stretchers ( 213 ), the second rib sections ( 221 ), the second stretchers ( 223 ), and the first rib sections ( 40 ) are made of FRP (Fiberglass Reinforced Plastics). 
   
   
       6 . The umbrella ( 1 ) of  claim 3 , wherein the first stretchers ( 213 ) and the second stretchers ( 223 ) are formed by a twin-FRP-pipe.
