The rollers are each mounted on separate pins and each pin has first and second ends, with the first ends fixed to the end plate that is operatively associated with the blind's clutches. Two of the rollers are operatively associated with the inner roller tube and sized and positioned to accommodate the receipt of the chain or cord of the inner roller tube. Two of the rollers are operatively associated with the outer roller tube and sized and positioned to accommodate the receipt of the chain or cord of the outer roller tube. The cover plate covers the second ends of the pins to prevent the chains or cords from being displaced from between adjacent rollers when received therebetween.</p> |
