Vertical blind

A vertical blind, comprising:

• a blind head, a plurality of carriers supported for reciprocating movement in said head, a plurality of holder means respectively supported in said carriers for pivotal movement and respectively adapted to support a plurality of vanes therefrom, and control means for controlling said reciprocating movement of said carriers and for controlling said pivotal movement of said holder means, said control means for controlling said reciprocating movement of said carriers comprising a cord having two substantially parallel strands extending through said carriers and substantially over the length of said blind head, and means associated with said cord for exerting a drag on said cord to keep said cord taut, said last-mentioned means comprising a carrier station through which said strands pass, means in said carrier station for engaging said strands, and clamping means for exerting adjustable pressure on said engaging means and thereby on said strands.

A vertical blind comprising:

• a blind head, a plurality of carriers supported for reciprocating movement in said head, a plurality of holder means respectively supported in said carriers for pivotal movement and respectively adapted to support a plurality of vanes therefrom, and control means for controlling said reciprocating movement of said carriers and for controlling said pivotal movement of said holder means, said control means for controlling said reciprocating movement of said carriers comprising a cord extending through said carriers, substantially over the length of said blind head, and through passage means in said blind head, and means associated with said cord for exerting a drag on said cord to keep said cord taut, including a plate arranged to engage said cord adjacent said passage means, and means for exerting pressure on said plate and thereby on said cord.

In a vertical blind having a blind head with a plurality of carriers supported for reciprocating movement in said head:

• a plurality of holder means respectively supported in said carriers for pivotal movement and respectively adapted to support a plurality of vanes therefrom, each of said holder means comprising a first shank, a second shank substantially parallel to but considerably shorter than said first shank and spaced therefrom sufficiently to form a first slot therebetween for receiving a vane to be supported from said holder means, and hook means connected to said first shank and adpated to support said vane in said first slot, said hook means and said second shank forming a second slot therebetween below said second shank, which second slot extends at an acute angle with respect to said first shank and which communicates with said first slot, whereby a vane to be suspended from said hook means is adapted to be introduced through said second slot into said first slot, said hook means having an inclined outer face below said second slot, the width of said hook means at said second slot being smaller than the width of said second shank at said second slot so that a vane when pushed from below will be guided along said inclined outer face and said hook means adjacent said second slot until it is caught in said second slot.
