ABSTRACT:
A slideably and rotatably mounted roller member performs a precision take up reel function in the environment of a track mounted, drawable, pleated window covering. The roller member slides along an axis coincident with its axis of rotation as it rotates so that cord being wound therearound attendant its rotation is taken up in the absence of overlapping. One end of the roller member is provided with a centrally bored and threaded plug that screw threadedly engages a fixed position screw member; as the roller member rotates, the engagement of the screw member and the bore drives the plug and hence the roller member in an axial direction. The slideable mount of the roller member is provided in the form of a base member which is slideably received within the roller member housing. A novel "F"-shaped track member is engaged by wheel members positioned in a novel wheel housing, and laterally opposed wheel housings are interconnnected by a rigid interconnecting member that conforms to the shape of the pleats formed in the window covering. The assembly ensures that the window covering remains level at all of its functional positions.
