ABSTRACT:
A spacer for lamella carriers of vertical lamella blinds comprises an oblong, strip-shaped section, an end connector element for positive engagement with the lamella carrier, as well as a detent arranged at its free end that can be guided into seating with the neighboring lamella carrier. For simplification of assembly and in order to avoid a spreading of the strip-shaped sections, the connector element of the spacer carriers two channels at its side facing away from the lamella carrier, these two channels being directed toward one another and their spacing and width essentially corresponding to the dimensions of the strip-shaped section of the spacer, so that the strip-shaped section of the spacer of the following lamella carrier is capable of sliding in these channels during extension of retraction. The upper terminating surface of the connector element that faces toward the lamella carrier is inclined relative to the longitudinal axis of the strip-shaped section, so that the strip-shaped sections of all spacers lie tightly on top of one another in imbricated fashion when the lamella carriers are brought together.
