ABSTRACT:
A venetian blind construction for use in a building having a recess adjacent a window, comprises, a drive gear for driving the blinds which has a hub portion with a receiving socket for a drive shaft which is contained in a separate venetian blind top box or housing. The drive shaft is supported on spaced apart bearing sleeves contained in the venetian blind housing, and the shaft may be slid axially in the support sleeve bearings after it is first supported on fixed brackets arranged alongside the drive gear so as to cause the shaft to engage in the socket recess to be driven by the drive gear. The shaft is of polygonal section, and it engages in a sleeve of a similar polygonal bore, and the sleeve is rotatably supported in the venetian blind top box housing. Individual slats of the blind are supported on a pull chain which is engaged over a sprocket affixed to a sleeve so that rotation of the drive shaft causes a rotation of the sprocket and movement of the pull chain supporting the blinds.
