Abstract: A lift-cord guide for window blind is disclosed to include a roller holder including a pull cord inlet and a pull cord outlet extending in a perpendicular manner relative to the pull cord inlet, and a first guide roller rotatably mounted in the roller holder at the intersection between the extending direction of the pull cord inlet and the extending direction of the pull cord outlet. The axial direction of the first guide roller obliquely intersects with the extending direction of the pull cord inlet, and defines with the extending direction of the pull cord outlet a contained angle smaller than 90-degrees. Thus, the lift-cord guide of the invention effectively reduces the turning angle of the pull cords, and smoothens the operation to open or close the blind slats.

Abstract: An antique blind slat fabrication method Includes the steps of a) preparing a slat substrate subject to a predetermined size, b) coating a surface of the slat substrate with a base coat, c) grinding the base-coated surface of the slat substrate, and d) coating the base coat with a wood grain paint.

Abstract: A window blind slat includes a metal sheet, a bottom layer, and a top layer. The metal sheet includes a top side and a bottom side. The bottom layer is attached to the bottom side of the metal sheet, having two end parts curved and then attached to the top side of the metal sheet. The top layer is attached to the top side of the metal sheet and top sides of the two end parts of the bottom layers.
