ABSTRACT:
A support member for horizontal members or elements in a traversable opening covering device is disclosed. In the preferred embodiment, the opening covering device is a vertical blind for a window opening. The vertical blind includes a plurality of vanes and carriers supporting the vanes, and a track structure for traversably supporting the carriers. The rod controls movement of the vanes, i.e. traversing or rotating of the vanes. In the preferred embodiment, the carriers are traversed by a cord arrangement and the support member also supports the cord. The support member comprises a body having an opening therein adapted to slidably receive the horizontally extending rod, shoulders or rollers disposed on opposed sides of the body adapted to be traversably received in the track structure, and another opening or a spring arrangement associated with the body adapted to receive a cord therein which is used to traverse the carriers and which is releasably and frictionally engaged with the opening or spring arrangement. Movement of the cord traverses the carriers and also traverses the support member from one end of the track structure to a predetermined supporting location at the central part of track structure. The support member is retained at the predetermined location at the central part of the track structure when the frictional engagement between the cord and support body is overcome so that further movement of the cord traverses the carriers but not the support member.
