Abstract
A spring motor with an improved take-up drum and idler gear assembly is disclosed. The spring motor includes a take-up drum proximate a drive drum with a coil spring interconnected between the two. First and second cord spools are mounted for rotation laterally adjacent the drive drum and take-up drum. The take-up drum is mounted about an idler gear which transfers torque from the first cord spool to the drive drum. Both the take-up drum and the idler gear are independently rotatable and are supported for rotation on first and second respective sides of each to thereby minimize binding between the idler gear and the take-up drum.
