ABSTRACT:
The present invention relates to a control system for venetian blinds. Through the control system the upper half of the blinds can be rotated independent of the lower half and vice versa. The control system employs two rotatable dowels, a forwardly located dowel and a rearward dowel. Rotation of the forward dowel effects rotation of the upper set of venetian blinds, while rotation of the rearward dowel effects rotation of the lower set of venetian blinds. The rotation is made possible by two sets of drawstrings. A forwardly located set of drawstrings is attached to the forward edges of the upper set of blinds. The forward set of drawstrings is controlled by the forward dowel. A rearwardly located set of drawstrings is attached to the rearward edges of the lower set of blinds. The rearward set of drawstrings is controlled by the rearward dowel.
