Patent ID: 8579004

Claim:
A covering system comprising: a first and a second segment, each segment having a first end and a second end; a shaft connecting the first ends of said segments to align said segments coaxially and transmit rotation from one segment to the other segment; and a link disposed at said first end of said first segment and arranged and constructed to selectively disconnect said first segment from said shaft without moving one of said first and second segments axially, wherein once decoupled said first segment is rotatable independently of said second segment, wherein said link includes a bushing attached to said first segment, said bushing including a ring member positioned to be rotatably manipulated by a user after the covering system has been installed, a barrel attached to said first segment and a clutch coupled between said barrel and said shaft having a first position and a second position, wherein in said first position said barrel is rotatably coupled to said shaft, and wherein in said second position, the barrel is decoupled from said shaft to allow said first segment to rotate with respect to said shaft.
