Abstract
A head structure for Venetian blind includes a head rail having a concave bottom surface, two mounting members assembled to the head rail and invisible from a front side of the head rail, and a slat tilting gear controlled via tilt cords instead of a rigid wand. The concave bottom surface of the head rail has a curvature close to that of slats of the Venetian blind, so that the slats in a fully lifted position can fitly bear against the bottom of the head rail to avoid deformation. The tilt cords, the invisibly assembled mounting members, and the lifted slats fitly bearing against the head rail not only creates beautiful integral appearance for the Venetian blind, but also enables reduced volume thereof for convenient packing and storage.
Claims7
A head structure for a Venetian blind comprising a substantially U-shaped head rail having a front portion, a bottom portion and a rear portion, two plastic mounting members and a slat tilting gear;
- said front portion including an upper end with a rearward and downward extending flange and said rear portion including an upper end with a forward extending flange and said bottom portion defining a concave surface having a curvature close to that of slats in a Venetian blind;
- said rear portion including a lower end with forward and downward projections forming a generally C-shaped channel between said bottom portion and said rear portion and a rib formed adjacent to said forward projection;
- each of said plastic mounting members made integral by injection molding to define a substantially L-shaped member having a top portion, a rear portion and an open space therebetween;
- said top portion of each of said mounting members including a front end forming a downward, forward and upward extending flange and a forward extending hold down plate, and said rear portion of each of said mounting members having a lower end forming a forward and upward extending flange forming a rib and a downward extending grip;
- said mounting member constructed for assembly to said head rail with said rearward and downward extending flange of said front portion of said head rail extending over said downward, forward and upward extending flange of said top portion of each of said mounting members and under said hold down plates, and in which said generally C-shaped channel of said rear portion extending over said forward and upward extending flange of said rear portion of each of said mounting members and against said rib and being releasable therefrom by said downward extending grip and whereby said mounting members are not visible from a front side of said head rail;
- and
- two tilt cords controlling said tilting gear to tilt slats of said Venetian blind.
