Umbrella having uneven cover or canopy

Abstract

An umbrella includes a central stick, a crown disposed on top of the stick, a slider slidably attached onto the central stick, an uneven canopy having a front portion shorter than two side portions of the canopy, and a rear portion longer than the side portions of the canopy, and a whale bone device for coupling the canopy to the central stick and for supporting the canopy on the central stick. The whale bone device includes one or more front strut assemblies for supporting the shorter front portion of the canopy, one or more side strut assemblies for supporting the side portions of the canopy, and one or more rear strut assemblies for supporting the longer rear portion of the canopy.

1 . An umbrella comprising:
 a central stick,   a crown disposed on top of said stick,   a slider slidably attached onto said central stick and movable up and down along said central stick,   an uneven canopy including two side portions, a front portion shorter than said side portions of said canopy, and a rear portion longer than said side portions of said canopy, and   a whale bone means for coupling said canopy to said central stick and for supporting said canopy on said central stick.   
   
   
       2 . The strut assembly as claimed in  claim 1 , wherein said whale bone means includes at least one front strut assembly for coupling and supporting said shorter front portion of said canopy, at least one side strut assembly for coupling and supporting said side portions of said canopy, and at least one rear strut assembly for coupling and supporting said longer rear portion of said canopy. 
   
   
       3 . The strut assembly as claimed in  claim 2 , wherein said at least one front strut assembly and said at least one side strut assembly each include an upper stave pivotally coupled to said crown, a lower stave pivotally coupled to said slider and pivotally coupled to a middle portion of said upper stave, a main stave pivotally coupled to said upper stave, and an outer stave pivotally coupled to said main stave. 
   
   
       4 . The strut assembly as claimed in  claim 3 , wherein said main stave is pivotally coupled to said lower stave with a lever. 
   
   
       5 . The strut assembly as claimed in  claim 3 , wherein said outer stave is pivotally coupled to said upper stave with a flexible member. 
   
   
       6 . The strut assembly as claimed in  claim 3 , wherein said upper stave of said at least one front strut assembly is shorter than said upper stave of said at least one side strut assembly. 
   
   
       7 . The strut assembly as claimed in  claim 3 , wherein said lower stave of said at least one front strut assembly is shorter than said lower stave of said at least one side strut assembly. 
   
   
       8 . The strut assembly as claimed in  claim 3 , wherein said main stave of said at least one front strut assembly is shorter than said main stave of said at least one side strut assembly. 
   
   
       9 . The strut assembly as claimed in  claim 3 , wherein said outer stave of said at least one front strut assembly is shorter than said outer stave of said at least one side strut assembly. 
   
   
       10 . The strut assembly as claimed in  claim 2 , wherein said at least one rear strut assembly includes an upper stave pivotally coupled to said crown, a lower stave pivotally coupled to said slider and having a middle portion pivotally coupled to said upper stave, a main stave pivotally coupled to said lower stave, and an outer stave pivotally coupled to said main stave. 
   
   
       11 . The strut assembly as claimed in  claim 10 , wherein said main stave is pivotally coupled to said upper stave with a lever. 
   
   
       12 . The strut assembly as claimed in  claim 10 , wherein said outer stave is pivotally coupled to said lower stave with a flexible member. 
   
   
       13 . The strut assembly as claimed in  claim 10 , wherein said at least one rear strut assembly includes an additional stave pivotally coupled to said outer stave. 
   
   
       14 . The strut assembly as claimed in  claim 13 , wherein said additional stave is pivotally coupled to said main stave with a flexible member. 
   
   
       15 . The strut assembly as claimed in  claim 10 , wherein said at least one rear strut assembly includes a stretcher coupled between said main stave and said crown for supporting said canopy. 
   
   
       16 . The strut assembly as claimed in  claim 15 , wherein said stretcher includes a knot engaged into a cavity of said crown. 
   
   
       17 . The strut assembly as claimed in  claim 1 , wherein said stick includes at least two telescoping stick sections retractably coupled together.
