Abstract: A door and window ornamental article positioning device includes a support unit equipped with stop plates and a support mount to be mounted to a central hollow-out portion of a fan-shaped blind body having a counterweight board fixedly attached to the underside of both end sides respectively. The stop plates and the support mount are respectively provided with connecting portions and coupling cavities to be joined to each other with a restricting space formed for the positioning of the fan-shaped blind body therein. The support mount has an arcutate support portion precisely abutting against the hollow-out portion, and wing panels with insert hooks extending at both external sides to engage with insert pieces of the counterweight boards. Via the separate design, the support unit can have a proper support mount assembled thereto to fit to various diameters of the fan-shaped blind body and stably position the central hollow-out portion thereby.

Abstract: A headrail covering structure for blinds comprises a headrail defined by a receiving channel to which a cord-winding control device, a movable seat, and a fixed seat are respectively mounted so as to control a lift cord and actuate a blind body collected upwards or expanded downwards thereby, forming a cordless window blind structure. The cord-winding control device and the fixed seat have the top surfaces respectively equipped with a connecting element composed of a set of upper and lower conjoining surfaces. A covering sheet identical to the headrail in length is provided to attach to the upper conjoining surfaces of the connecting elements, while the lower conjoining surfaces of the connecting elements are respectively adhered onto the cord-winding control device and the fixed seat. Therefore, via the sheltering of the covering sheet, the receiving channel of the headrail can achieve dustproof effect and protect each assembling part accommodated therein.
