Patent ID: 8267234

Claim:
Force transmitting coupling for drivingly coupling a pair of adjacent axially aligned rollers for adjacent architectural coverings, the coupling including: a first coupling member including a flange drivingly connected to one of the rollers; a second coupling member drivingly connected to the other one of the rollers including an axially extending hub; a perimeter rim connected to and concentric with said hub; and an annular central region radially extending from an outer side surface of said hub to said rim, said central region defining a plurality of apertures forming spokes therebetween, where said spokes extend between said outer side surface of said hub to said rim, said rim forming a recess with said central region; and mating engagement means on the first and second coupling members adapted to establish mating engagement in an axial direction between the first and second coupling members to transmit a drive force from one of the first and second coupling members to another of the first and second coupling members, wherein said spokes cushion torque forces applied to the mating engagement means, and said flange of said first coupling member nests within said recess.
