Blind with semitransparent sheets of drapery material

Abstract

A blind includes a structural assembly including a head rail, a bottom stiffener strip, horizontal slats suspended between the head rail and the stiffener strip, and two spaced lines started from the stiffener strip, passed the slats, and terminated at the head rail such that manipulating the lines will raise or lower the slats; a drapery assembly including front and back semitransparent sheets of drapery material and horizontal stiffener members spaced on the sheets of drapery material; and vertically spaced positioning assemblies. Any two adjacent positioning assemblies are adapted to dispose at least one of the slats therebetween. The positioning assemblies are adapted to releasably secure to the stiffener members.

1 . A blind comprising: 
 a structural assembly including a head rail, a bottom stiffener strip, a plurality of horizontal slats equally spaced, suspended between the head rail and the stiffener strip, and a couple of lines wherein one line starts from one side of the stiffener strip, passes one sides of the slats, and terminates at one side the head rail, and the other line starts from the other side of the stiffener strip, passes the other sides of the slats, and terminates at the other side of the head rail such that manipulating the lines will raise or lower the slats;    a semitransparent drapery assembly including a front semitransparent sheet of drapery material, a back semitransparent sheet of drapery material, and a plurality of horizontal stiffener members spaced on the front and back semitransparent sheets of drapery material; and    a plurality of vertically spaced positioning assemblies wherein any two adjacent positioning assemblies are adapted to dispose at least one of the slats therebetween;    wherein the positioning assemblies are adapted to releasably secure to the stiffener members.    
     
     
         2 . The blind of  claim 1 , wherein the positioning assembly includes two elongate members of C section at front and back ends, the C-shaped member including a groove adapted to securely receive the stiffener member, and a plate interconnected the C-shaped members.  
     
     
         3 . The blind of  claim 2 , wherein the plate includes two openings each adapted to permit the line to pass.  
     
     
         4 . The blind of  claim 1 , wherein the positioning assembly includes an elongate member of C section at one end and including a groove adapted to securely receive the stiffener member, and an extension integrally formed with either side of the slat.  
     
     
         5 . The blind of  claim 1 , wherein the stiffener member includes a bar and an enclosure for receiving the bar.  
     
     
         6 . The blind of  claim 5 , wherein the enclosure is secured to either one of the front and back semitransparent sheets of drapery material by sewing.  
     
     
         7 . The blind of  claim 1 , wherein the positioning assembly includes two elongate members of C section at front and back ends, the C-shaped member including a groove adapted to securely receive the stiffener member, and a plate interconnected the C-shaped members and integrally formed with a bottom of either side of the slat.  
     
     
         8 . The blind of  claim 1 , wherein the back semitransparent sheet of drapery material is adapted to releasably secure to a back of the head rail.  
     
     
         9 . The blind of  claim 1 , wherein the structural assembly further comprises a valance adapted to releasably secure to a front of the head rail.  
     
     
         10 . The blind of  claim 8 , further comprising a Velcro type fastener adapted to releasably secure the back semitransparent sheet of drapery material to the back of the head rail.  
     
     
         11 . The blind of  claim 9 , further comprising a Velcro type fastener adapted to releasably secure the valance to the front of the head rail.  
     
     
         12 . The blind of  claim 2 , wherein the stiffener member is laterally inserted into the groove.  
     
     
         13 . The blind of  claim 4 , wherein the stiffener member is laterally inserted into the groove.  
     
     
         14 . The blind of  claim 7 , wherein the stiffener member is laterally inserted into the groove.
