Removable, retractable sunshade for a flotation tube

Abstract

A portable, retractable, and removable ultraviolet protective sunshade assembly that attaches to the headrest of a river or pool flotation tube by way of a backrest frame. The sunshade assembly provides a support frame that is telescopically associated with the backrest frame, enabling selective elevational adjustments of the support frame relative to the flotation tube. A shade frame is pivotably connected to the opposing end of the support frame so that a shade barrier is selectively rotatable between a plurality of operative positions over the user of the flotation tube as well as out of the way of the user.

What is claimed is: 
     
         1 . A sunshade assembly for a flotation device, the sunshade assembly comprising:
 a support frame telescopically associated with a backrest of the flotation device, wherein the support frame is configured to selectively adjustment an elevation of the support frame relative to the backrest; and   a shade frame pivotably connected to a distal end of the support frame so that a shade barrier is selectively rotatable between a plurality of operative positions over the flotation device.   
     
     
         2 . The sunshade assembly of  claim 1 , further comprising one or more upright supports operatively associated with the backrest, wherein a proximal end of the support frame is telescopically associated with the one or more upright supports so that the support frame is selectively and linearly movable between one or more retracted positions and one or more extended positions. 
     
     
         3 . The sunshade assembly of  claim 2 , wherein each upright support provides a plurality of linearly spaced apart snap holes to which a portion of the proximal end of the support frame can operatively associate with to be selectively movable between the one or more retracted positions and the one or more extended positions. 
     
     
         4 . The sunshade assembly of  claim 3 , further comprising one or more snap protrusions provided by the proximal end of the support frame for selectively engaging one of the plurality of linearly spaced apart snap holes. 
     
     
         5 . The sunshade assembly of  claim 4 , further comprising a pivot mechanism that pivotably connects the shade frame to the distal end of the support frame. 
     
     
         6 . The sunshade assembly of  claim 5 , wherein the support frame provides one or more pivot points that are received inside one or more lumens of the pivot mechanism. 
     
     
         7 . The sunshade assembly of  claim 6 , wherein the one or more pivot points are two pivot points that are opposing ends of the shade frame. 
     
     
         8 . The sunshade assembly of  claim 7 , further comprising an ultraviolet shade barrier extending over the shade frame. 
     
     
         9 . The sunshade assembly of  claim 2 , further comprising a backrest frame that operatively associates with the backrest of the flotation device, wherein the backrest is a C-shape dimensioned to snugly engage at least three sides of said backrest, and wherein a rear surface of the backrest provides attachment points for the one or more upright supports. 
     
     
         10 . The sunshade assembly of  claim 2 , wherein the one or more upright supports are directly connected to the backrest.
