Abstract: There is provided a spring assisted electric motor driven lifting mechanism for lifting and lowering a blind which permits the quick and easy matching of the spring assist pre-rotation to the torque output of the electric motor. The device includes an elongated cylinder coupled to the blind such that rotating the cylinder about its axis lifts and lowers the blind. Coupled to the elongated cylinder is an electric motor which is configured to rotate the elongated cylinder about its axis. A torsion spring is coupled to the cylinder for biasing the elongated cylinder to at least partially neutralize the weight of the blind. The torsion spring is in turn coupled to a spring preload adjuster which is configured to adjust the tension on the torsion spring by moving an adjustment member. The spring preload adjuster is further configured such that the adjustment member extends perpendicularly away from the axis of the elongated cylinder.
