8175 VERTICAL VENETIAN BLIND CONSTRUCTION Abstract of the Disclosure: A vertical venetian blind construction in which carriages having rotatable slat carriers are mounted for movement along a horizontal channel by traverse cords that extend lengthwise of the channel. A spline shaft extends lengthwise of the channel and the carri- ages have rack gear that mesh with the spline shaft and with a pinion on the slat carrier for rotating the slat carriers in response to the turning of the shaft. The carriages are formed with passages between their side walls and opening at the top of the carriage and which is shaped to allow insertion of the slat carrier and rack member as a subassembly into the carriage from the top thereof and to laterally retain the rack member in meshing engagement with the carrier pinion during and after insertion of the subassembly in the carriage, and the slat carriers and rack members have interengaging parts to inhibit relative movement of the rack member and slat carrier in a direction paralleling the slat carrier axis during and after insertion of the subassembly into the carrier.
