Window covering

A window covering comprising:

• (a) a head rail;
• (b) a plurality of slats depending from said head rail having alignable openings therein spaced inwardly from the edges of said slats, wherein each of said slats has a pivot point, wherein said slats are moveable about their pivot points from a closed position which prevents viewing through the window covering through an opened position which allows viewing therethrough, wherein said slats are configured and positioned relative to one another so as to form contiguous dead air cells therebetween in axial alignment when said slats are in the closed position;
• (c) means operatively connected to said slats for pivoting said slats about their pivoting points from the closed contiguous dead air cell position through the opened see-through position, and wherein said pivoting means includes spaced apart members wherein at least one member of which extends through aligned openings in said slats and is positioned inwardly from said edges of said slats to hide said member when said slats are in the closed position, and a plurality of transverse members which are connected to said spaced apart members for supporting said slats;
• (d) means independent of said pivoting means for gathering and spacing said slats along said aligned axis.

A window covering comprising:

• (a) a head rail;
• (b) a plurality of slats depending from said head rail having at least one column of alignable openings therein spaced inwardly from the edges of said slats, wherein each of said slats has a pivot point, wherein said slats are moveable about their pivot points from a closed position which prevents viewing through the window covering through an opened position which allows viewing therethrough, and wherein said slats are positioned and configured relative to one another so as to form contiguous dead air cells therebetween in axial alignment when said slats are in the closed position;
• (c) pivoting means operatively connected to said slats for pivoting said slats about their pivoting points from the closed contiguous dead air cell position through the opened see-through position, and wherein said pivoting means includes spaced apart members, each spaced apart member corresponding to a respective column of aligned openings, wherein at least one of said spaced apart members extends through a respective column of said aligned openings in said slats and is positioned inwardly from said edges of said slats to hide said member when said slats are in the closed position, and wherein said one member has a plurality of nodes which provide support ledges for said slats;
• and
• (d) gathering and spacing means independent of said pivoting means for gathering and spacing said slats along said aligned axis.

A window covering comprising:

• (a) a head rail for attachment to a window frame;
• (b) a plurality of slats between said rails pivotally moveable between a closed position to prevent viewing through the window covering and an opened position to allow viewing therethrough, wherein each of said slats is configured to include a portion on one side of the pivot point of said slat which is above the pivot point of said slat and a portion on the other side of the pivot point of said slat which is below the pivot point when said slat is in its opened position, wherein said configured slats are positioned relative to one another so as to form a row of contiguous dead air cells along the longitudinal axis of said slats and between said rails having at least two layers of slats along the length of each of said cells when said slats are in the closed position;
• (c) means operatively connected to said slats for pivoting said slats from their closed contiguous dead air cell position through their opened see-through position;
• (d) a bottom rail below said slats that remains stationary when said slats are pivoted by said pivoting means;
• and
• (e) means independent of said pivoting means operatively connected to said bottom rail for gathering and spacing said slats to and from said top rail independent of the position of said slats.

A venetian blind comprising:

• (a) a head rail for attachment to a window frame;
• (b) a plurality of generally S-shaped slats therebetween wherein said slats include leading and trailing edges and are moveable about pivot points to a closed position with the edges of contiguous slats in contact with one another for preventing viewing through said blind and to an opened position for viewing therethrough, and wherein said generally S-shaped slats are positioned relative to one another with their pivot points spaced apart at a distance less than half the width of a slat so as to form a row of longitudinal contiguous dead air cells between said rails when the edges of contiguous slats are in contact with one another in the closed position of the blind;
• (c) pivoting means extending from said head rail and operatively connected to said slats for pivoting said slats from their closed contiguous cell forming position through their open see-through position;
• (d) a bottom rail below said slats that remains stationary when said slats are pivoted by said pivoting means;
• and
• (e) means independent of said pivoting means extending from said head rail and operatively connected to said bottom rail for raising and lowering said slats and bottom rail to and from said head rail regardless of the position of said slats.
