Vertical shade

Abstract

A window covering or shade for selectively covering, uncovering and providing a light filtering position where visibility is substantially blocked but light is allowed to enter therethrough. The window covering may include, among other components, a head rail and a unitary sheet of material. The window covering is preferably substantially constructed of a supple or non-rigid material.

1 . A window covering for covering a window comprising: 
 a headrail; and    a unitary sheet of material suspended vertically from said headrail, said unitary sheet being configured so as to define at least two soft vane sections and at least one portion therebetween, said soft vane sections being rotatable between a first position substantially parallel to said window, and a second position substantially perpendicular to said window, said portion being substantially curved when said soft vane sections are in said second position.    
   
   
       2 . The window covering according to  claim 1 , wherein said soft vane sections are substantially opaque and said portions are substantially sheer.  
   
   
       3 . The window covering according to  claim 1 , wherein said soft vane sections are slideably and rotatably engaged with said headrail so as to allow for both traversing and rotational movement of said soft vane sections with respect to said headrail.  
   
   
       4 . The window covering according to  claim 3 , wherein said window covering at least partially blocks both visibility and light conducted through said window, when said soft vane sections are in said first position.  
   
   
       5 . The window covering according to  claim 4 , wherein said window covering at least partially blocks visibility through said window and at least partially allows for light to be conducted therethrough, when said soft vane sections are in said second position.  
   
   
       6 . The window covering according  claim 5 , further including at least one hem bar attached to a top portion of at least one said soft vane section and said headrail.  
   
   
       7 . The window covering according to  claim 1 , wherein said headrail further includes means for rotating and slideably moving said soft vane sections.  
   
   
       8 . The window covering according to  claim 1 , wherein said window covering includes at least two unitary sheets of material, each of said sheets being configured so as to define at least two soft vane sections and at least one portion.  
   
   
       9 . The window covering according to  claim 8 , wherein said unitary sheets are attached together at least partially along adjacent soft vane sections.  
   
   
       10 . The window covering according to  claim 9 , further including a rigid slat placed between said adjacent soft vane sections.  
   
   
       11 . The window covering according to  claim 1 , wherein said unitary sheet of material is removably attached to said headrail.  
   
   
       12 . A window covering comprising: 
 a headrail; and    a unitary sheet of material suspended vertically from said headrail, said unitary sheet being configured to define at least two soft vane sections and at least one non-rigid portion therebetween, said soft vane sections being capable of traversing movement between a closed position where said window is substantially covered by said unitary sheet and an open position where said window is substantially uncovered by said unitary sheet, said soft vane sections being capable of rotational movement between a first position where said covering at least partially blocks both visibility and light conducted through said window and a second position where said covering at least partially blocks visibility through said window and at least partially allows for light to be conducted therethrough.    
   
   
       13 . The window covering according to  claim 12 , wherein said soft vane sections are substantially opaque and said portions are substantially sheer.  
   
   
       14 . The window covering according to  claim 13 , wherein said soft vane sections are disposed substantially parallel to said window in said first position.  
   
   
       15 . The window covering according to  claim 14 , wherein said soft vane sections are disposed substantially perpendicular to said window and said portion being substantially curved when said soft vane sections are in said second position.  
   
   
       16 . The window covering according to  claim 12 , wherein said headrail includes means for translating and rotating said soft vane sections.  
   
   
       17 . The window covering according to  claim 12 , wherein said unitary sheet of material is removably attached to said headrail.  
   
   
       18 . A window covering comprising: 
 a headrail; and    a plurality of unitary sheets of material suspended vertically from said headrail, each of said unitary sheets being configured to define at least two soft vane sections and a portion therebetween, said soft vane sections being rotatable between a first position substantially parallel to said window, and a second position substantially perpendicular to said window, said portions being substantially curved when said soft vane sections are in said second position.    
   
   
       19 . The window covering according to  claim 18 , wherein said soft vane sections are substantially opaque and said portions are substantially sheer.  
   
   
       20 . The window covering according to  claim 18 , wherein said soft vane sections are slideably and rotatably engaged with said headrail so as to allow for both traversing and rotational movement of said soft vane sections with respect to said headrail.  
   
   
       21 . The window covering according to  claim 20 , wherein said window covering at least partially blocks both visibility and light conducted through said window, when said soft vane sections are in said first position.  
   
   
       22 . The window covering according to  claim 21 , wherein said window covering at least partially blocks visibility through said window and at least partially allows for light to be conducted therethrough, when said soft vane sections are in said second position.  
   
   
       23 . The window covering according  claim 18 , further including at least one hem bar attached to a top portion of at least one said soft vane section and said headrail.  
   
   
       24 . The window covering according to  claim 23 , wherein said headrail further includes means for rotating and slideably moving said soft vane sections.  
   
   
       25 . The window covering according to  claim 18 , wherein said unitary sheets are attached together at least partially along adjacent soft vane sections.  
   
   
       26 . The window covering according to  claim 25 , further including a rigid slat placed between said adjacent soft vane sections.  
   
   
       27 . The window covering according to  claim 18 , wherein each of said plurality of unitary sheets are removably attached to said headrail.
