Abstract: A dual-purpose fixing core for a blind includes a core rod secured in the interior and axially bored with a central shaft hole. The fixing core is axially formed inside with an accommodating chamber above the core rod. The accommodating chamber has at least one side formed with an opening and has its upper side formed with a top wall axially bored with two parallel elongated slots for the ladder strap or the ladder cord of a blind to pass therethrough. The fixing core is provided with an upright plate extending outward diametrically from the outer circumferential side of the core rod to the top wall between the two elongated slots. Thus, the ladder straps or the ladder cords of a blind can be optionally fixed with in the two elongated slots, facilitating assembly of the ladder straps or ladder cords and reducing the producing cost of the fixing cores.

Abstract: The present invention relates to a slat-actuating and positioning device for venetian blinds having a plurality of restriction cords provided in between two main cords to position the blind slats of the venetian blinds. A recessed positioning slot is provided on the blind slat corresponding to the main cords such that an actuating and positioning structure formed from the blinds and the main cords. A plurality of lugs are provided at intervals along the main cord for the passage of a suspension cord to the base seat below the blind slats. The structure of the present invention provides excellent stability in actuating the blind slats and improves the longevity of the venetian blinds.

Abstract: The present invention relates to an improved structure of a driving mechanism for a venetian blind, wherein the frame body is provided with fixing seats having being mounted with blind slat control element. The control element is driven by a control shaft and a pulling cord is connected to the blind slats. A suspension cord passes through individual blind slat and combines with the base slat at the bottom of the blind slat such that the suspension cord can pull the base slat to close or open the individual blind slat.
