Adjustable drive coupling for adjacent architectural coverings

摘要

A force transmitting coupling (30) for drivingly coupling winding devices of adjacent architectural coverings. The coupling includes a first coupling member (31), a second coupling member (33), and mating engagement means on the first and second coupling members adapted to establish mating engagement between the first and second coupling member to transmit a drive force from one of the first and second coupling members to another of the first and second coupling members. The second coupling member includes a hub (71) and the engaging means on the second coupling member are resiliently connected to the hub.
