ABSTRACT:
An operating mechanism for a window treatment where the window treatment utilizes a plurality of sheet material louvers. The operating mechanism can be used when the louvers are mounted in a vertical direction or a horizontal direction. The operating mechanism in each case includes a support device for each louver which is mounted in conjunction with an elongated guide track. The support device includes a sleeve with a connecting stud of its respective louver to be secured to this sleeve. Integrally mounted on and extending transversely of the sleeve is a transverse arm. A connecting cord assembly is to be mounted in connection with the transverse arms of each of the support devices of the guide track. Manipulation of the cord assembly is for the purpose of pivoting each of the support devices and thereby pivoting each of the louvers from an aligned position, where the louvers combine to form a structure similar to a solid panel, and a parallel position forming large spaces between the louvers, forming a structure similar to an open window.
