Abstract
Abstract In a vertical blind with a blind head, a tilt rod for tilting vanes suspended from the blind head in carriers, and a traverse cord for reciprocating the carriers in the head to thereby open and close the blind: a lever connected to the tilt rod for rotation therewith and having an opening spaced from the tilt rod and through which the traverse cord passes. Rotation of the tilt rod will bend and squeeze the traverse cord and thereby prevent its reciprocation when the vanes of the blind are tilted closed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
In a vertical blind having a blind head, a tilt rod rotatably supported in said head, a plurality of carriers supported in said head and of which at least some are longitudinally reciprocably supported in said head, a plurality of vane holders respectively rotatably supported in said carriers, means connecting said vane holders to said tilt rod for rotation therewith, means operatively connected to said tilt rod for rotating the same and thereby said vane holders, and traverse cord means having two interconnected strands, each operatively connected to said plurality of carriers such that reciprocation of said cord will reciprocate said reciprocable carriers: means connected to said tilt rod for rotation therewith and including means for engaging one of said strands of said traverse cord such that rotation of said tilt rod through a predetermined angle of rotation will bend said engaged portion of said strand and prevent reciprocation of said cord.
Claim 2
Dependent Claim
152 words
In a vertical blind having a blind head, a tilt rod rotatably supported in said head, a plurality of carriers supported in said head and of which at least some are longitudinally reciprocably supported in said head, a plurality of vane holders respectively rotatably supported in said carriers, means connecting said vane holders to said tilt rod for rotation therewith, means operatively connected to said tilt rod for rotating the same and thereby said vane holders, and traverse cord means having two interconnected strands, each operatively connected to said plurality of carriers such that reciprocation of said cord will reciprocate said reciprocable carriers: means connected to said tilt rod for rotation therewith and including means for engaging one of said strands of said traverse cord such that rotation of said tilt rod through a predetermined angle of rotation will bend said engaged portion of said strand and prevent reciprocation of said cord.
Claim 3
Dependent Claim
26 words
The combination of claim 1, wherein said means connected to said tilt rod is a lever mounted on said tilt rod adjacent one of said carriers.
Claim 4
Dependent Claim
16 words
The combination of claim 2, wherein said one carrier is longitudinally non-reciprocable supported in said head.
Claim 5
Dependent Claim
24 words
The combination according to claim 2, wherein said lever is provided with an opening spaced from said tilt rod for receiving said cord strand.
Claim 6
Dependent Claim
50 words
The combination according to claim 2, 3 or 4, wherein said lever is longitudinally spaced from said one carrier a distance sufficient such that upon rotation of said tilt rod through said predetermined angle of rotation said engaged traverse cord strand becomes squeezed between said lever and said one carrier.
Claim 7
Dependent Claim
48 words
The combination according to claim 5, wherein said lever is provided with a further opening for receiving said tilt rod, said tilt rod having a groove, and said lever having means for engaging said groove to thereby fix the position of said lever relative to said tilt rod.
