发明名称 Operator for venetian blinds combination operator and venetian blind, and method of operating venetian blinds
摘要 A venetian blind incorporating a wand having an operator thereon at any desired position. The operator is nonrotatably associated with the wand, and the wand and operator are so constructed that longitudinal shifting of the operator rotates the wand about its axis. Resilient frictional drag prongs are incorporated in the operator to prevent undesided movement thereof, as by gravity. A stop and bearing element is mounted on the end of the wand.
