Sun screen device

Abstract

A sun screen device includes a support unit, a flexible screen body, a collapsible frame, and a cylinder-and-piston rod assembly. The flexible screen body is secured to the support unit. The collapsible frame is coupled to the support unit and the flexible screen body, and is operable between an extended position to thereby expand the flexible screen body, and a retracted position to thereby contract the flexible screen body. The cylinder-and-piston rod assembly is coupled pivotably to the support unit and the collapsible frame for urging movement of the collapsible frame to the extended position.

1 . A sun screen device, comprising:
 a support unit;   a flexible screen body secured to said support unit;   a collapsible frame coupled to said support unit and said flexible screen body, and operable between an extended position to thereby expand said flexible screen body, and a retracted position to thereby contract said flexible screen body; and   a cylinder-and-piston rod assembly coupled pivotably to said support unit and said collapsible frame for urging movement of said collapsible frame to the extended position.   
   
   
       2 . The sun screen device as claimed in  claim 1 , wherein said collapsible frame includes a frame part that includes first and second frame portions, said first frame portion of said frame part having a first end coupled pivotably to said support unit, and a second end opposite to said first end thereof, said second frame portion of said frame part having a first end coupled pivotably to said second end of said first frame portion of said frame part, and a second end opposite to said first end thereof and coupled pivotably to said flexible screen body,
 said cylinder-and-piston rod assembly being coupled pivotably to said support unit and said first frame portion of said frame part of said collapsible frame.   
   
   
       3 . The sun screen device as claimed in  claim 2 , further comprising:
 a first linking arm coupled pivotably to said support unit; and   a second linking arm coupled pivotably to said first frame portion of said frame part of said collapsible frame,   said cylinder-and-piston rod assembly being coupled pivotably to said support unit and said first and second linking arms.   
   
   
       4 . The sun screen device as claimed in  claim 3 , further comprising an adjusting unit for adjusting an angle between said cylinder-and-piston rod assembly and said support unit, said adjusting unit including
 a first adjusting member slidable along said support unit, and   a second adjusting member coupled to said support unit and said first adjusting member, and operable so as to dispose and retain said first adjusting member at different positions along said support unit,   said first linking arm being coupled pivotably to said support unit through said first adjusting member of said adjusting unit.   
   
   
       5 . The sun screen device as claimed in  claim 4 , wherein said first adjusting member is formed with a threaded hole, and said second adjusting member is coupled rotatably to said support unit, and is in the form of a screw rod for threadedly engaging said first adjusting member. 
   
   
       6 . The sun screen device as claimed in  claim 1 , further comprising a retaining unit for retaining said collapsible frame at the retracted position, said retaining unit including
 a first retaining member that is mounted on said support unit, and   a second retaining member that is mounted on said flexible screen body and that engages releasably said first retaining unit.   
   
   
       7 . The sun screen device as claimed in  claim 6 , wherein one of said first and second retaining members is formed with a groove, and the other of said first and second retaining members has a hook shape for engaging releasably said groove. 
   
   
       8 . The sun screen device as claimed in  claim 1 , wherein said flexible screen body has a secured end secured to said support unit, and a free end opposite to said secured end thereof, said sun screen device further comprising a batten provided along said free end of said flexible screen body, said collapsible frame being coupled to said support unit and said free end of said flexible screen body.
