ABSTRACT:
Venetian blinds, pleated blinds or the like, suspended in a cord drive system mounted in a housing, adapted to be positioned between the glass panes in a double glass window, particularly an insulating glass unit. The cord drive system is connected with a laterally arranged, longitudinal support shaft (16), mounted in the housing, which support shaft (16) is arranged rotatable as well as laterally displaceable in axial direction in order to accomplish winding and dewinding of the cord drives (10,12;66,68;78,78') in one single layer along parts of the support shaft, in order to hoist or ower the blind, respectively. The support shaft (16) is provided with threads in engagement with a threaded member (24,28), which is not rotatably connected in said housing (2), effecting that said support shaft (16) by rotation synchonously is being moved in axial direction.
