Curtain supporting and positioning combination

Claim 2

A traverse rod and curtain support combination comprising: a pair of master carriers for transporting the mating margins of a pair of curtain components between an opened and a closed position; a pull cord in the form of a loop mounted longitudinally of said rod with one strand of the loop attached to one said master carrier and the other strand attached to the other master carrier, whereby pulling one strand of the loop pulls the masters apart to the opened position and pulling the other strand pulls the masters in the opposite direction to the closed position at a point near the center of said rod but separated therefrom by a predetermined specific dimension, means at one said master carrier for providing a limited dimension of lost motion between said draw cord and the master, said dimension of lost motion being equal to said predetermined specific dimension to one side of the centerline of the curtain at which the masters are intended to meet in the closed position whereby when one master arrives at the opened or closed position before the other master has reached its corresponding position, said cord can be pulled additionally to bring the other master to its corresponding position.

Claim 3

The traverse rod and curtain support combination defined in claim 1 further characterized by said lost motion means comprising a pair of interconnected lost motion loops with one strand of each lost motion loop connected to the carrier and the other strand thereof extending longitudinally of the rod whereby pulling the draw cord relative to the master carrier causes the position of the connection between the lost motion loops to shift longitudinally of the master carrier.

Claim 4

The traverse rod and curtain support combination defined in claim 2 further characterized by the connection between said lost motion loops comprising a ring.

Claim 5

A curtain and support combination comprising: a curtain rod; means for mounting said rod on a base; a curtain comprising a pair of curtain components, one of which has substantially more material width than the other; means for supporting said curtain components on said rod with the outside lateral edges of each curtain component fixed to said rod but with the remaining portions of said curtain components sliding on said rod between an opened position at which each curtain component is gathered at the respective ends of the rod to a closed position at which the curtain components touch at the mid-point of said rod; means including a pull cord for drawing said curtain components between said opened and closed positions; means associated with each curtain component for limiting its travel at its own respective opened and closed positions; and lost motion means associated with said draw cord for providing limited lost motion for continuing to draw one curtain component after the other has reached the limit of its travel in any one direction by a dimension equal to the difference in width between said curtain components.

Claim 6

A curtain and support combination comprising: a curtain rod; means for mounting said rod on a base; a curtain comprising a pair of curtain components, one of which has substantially more material width than the other; means for supporting said curtain components on said rod with the outside lateral edges of each curtain component fixed to said rod but with the remaining portions of said curtain components sliding on said rod between an opened position at which each curtain component is gathered at the respective ends of the rod to a closed position at which the curtain components touch at the mid-point of said rod; means including a pull cord for drawing said curtain components between said opened and closed positions; means associated with each curtain component for limiting its travel at its own respective opened and closed positions; and lost motion means associated with said draw cord for providing limited lost motion for continuing to draw one curtain component after the other has reached the limit of its travel in any one direction by a dimension equal to the difference in width between said curtain components.

Claim 7

A curtain and support combination comprising: a curtain rod; means for mounting the rod on a base; a curtain comprising a multiplicity of vertically arranged, hinged slats divided into right and left hand curtain components; right and left hand master carriers mounted to move relative to said rod from a closed position at a relatively central point on said rod to an opened position with one master near each end of said rod; a multiplicity of idler carriers mounted to slide on said rod; means for pivotally connecting the top of each slat to one said carrier to pivot about a vertical axis on the longitudinal center line of each slat with the innermost slat of each curtain component being connected to one said master carrier and the idler which supports the outermost slat of each curtain component is connected, fixed against sliding motion relative to said rod at the end thereof; means including a draw cord for moving the master carriers between the opened to the closed positions; means at the tops of said slats for limiting the pivotal motion of said slats relative to each other to a specific predetermined angle; said curtain components dimensioned in relation to said limiting means and said rod so that said slats are at the maximum angle of divergence relative to each other when the curtain is in the closed position with the inner slat of each curtain component lying in close, parallel, overlapping relation; and lost-motion means associated with the draw cord and one master carrier for moving the other master to the fully opened and fully closed positions after the first master carrier has reached such a position.

Claim 8

A curtain and support combination comprising: a curtain rod; means for mounting the rod on a base; a curtain comprising a multiplicity of vertically arranged, hinged slats divided into right and left hand curtain components; right and left hand master carriers mounted to move relative to said rod from a closed position at a relatively central point on said rod to an opened position with one master near each end of said rod; a multiplicity of idler carriers mounted to slide on said rod; means for pivotally connecting the top of each slat to one said carrier to pivot about a vertical axis on the longitudinal center line of each slat with the innermost slat of each curtain component being connected to one said master carrier and the idler which supports the outermost slat of each curtain component is connected, fixed against sliding motion relative to said rod at the end thereof; means including a draw cord for moving the master carriers between the opened to the closed positions; means at the tops of said slats for limiting the pivotal motion of said slats relative to each other to a specific predetermined angle; said curtain components dimensioned in relation to said limiting means and said rod so that said slats are at the maximum angle of divergence relative to each other when the curtain is in the closed position with the inner slat of each curtain component lying in close, parallel, overlapping relation; and lost-motion means associated with the draw cord and one master carrier for moving the other master to the fully opened and fully closed positions after the first master carrier has reached such a position.

Claim 9

The curtain and support combination defined in claim 5 further characterized by said rod comprising an inverted U-shaped cross section, having a slot along the underside thereof; an upstanding track adjacent to said slat, and a pulley on each said master and idler carriers riding on said track.

Claim 10

The curtain and support combination defined in claim 5 further characterized by one said curtain component having at least one more slat than the other said component.

Claim 11

The traverse rod and curtain support combination defined in claim 5 further characterized by said lost-motion means comprising a pair of interconnected lost-motion loops with one strand of each lost-motion loop connected to the carrier and the other strand thereof extending longitudinally of the rod whereby pulling the draw cord relative to the master carrier causes the position of the connection between the lost motion loops to shift longitudinally of the master carrier.
