Patent ID: 7950437

Claim:
A window covering comprising: a first rail, the first rail having a first end and a second end opposite the first end; window covering material adjacent the first rail, the window covering material moveable from a retracted position to an extended position; at least one lift cord extending through the window covering material to the first rail; a plurality of pulleys positioned adjacent the first rail, each pulley having a surface over which at least one cord passes that defines a circumference; at least one spring motor adjacent the first rail, at least one spring motor cord extending from the at least one spring motor, the at least one spring motor cord configured to extend away from the at least one spring motor along a path defined by at least one of the plurality of pulleys when the window covering material is extended from the retracted position to the extended position and configured to be retracted toward the at least one spring motor along the path when the window covering material is retracted from the extended position to the retracted position; and a rigid connector attached to the at least one spring motor cord and the at least one lift cord, the connector being sized and configured to permit the at least one spring motor cord, connector and a portion of the at least one lift cord to pass along at least one of the plurality of pulleys during movement along the path, the connector having a length that is not greater than ⅙ of the circumference of at least one of the pulleys the connector passes over when the window covering material is extended from the retracted position to the extended position.
