Abstract
Abstract A prefabricated kit for the assembly of a composite slat which can be used in a venetian blind has two or more elongated first slat sections which can be separably coupled to each other by one or more connecting slat sections. The end portions of the connecting slat sections can be slidably telescoped into the adjacent end portions of neighboring first slat sections or vice versa. At least one outer slat section, which is one of the first slat sections, can be assembled of two shorter sections one of which carries a longitudinally outwardly extending guide pin for reception in a guide rail in the door or window opening wherein the venetian blind utilizing the slat is installed with its slats in vertical or horizontal positions. The connecting slat sections have apertures for the gathering tape or cord which is used to move the neighboring slats of a blind nearer to each other or to permit their movement away from one another.
