Abstract: The present invention provides a ladder cord lattice for window blinds. The ladder cord lattice includes a front strip, a rear strip and multiple slat sustaining portion arranged at intervals between the front and rear strips. There is a connecting and positioning portion, being integrally formed on the top of front and rear strip and lacking the slat sustaining portion. There are tailoring point identification bulges, and snapper locating point identification bulges. There is a clear identification point for tailoring and feeding of ladder cord lattice and for fixing of the snapper via the tailoring point identification bulges and snapper locating point identification bulges, thus reducing the error of feeding and assembly, and improving the operating efficiency, accuracy and quality for higher applicability and industrial efficiency.

Abstract: The present invention provides a venetian blind with a thin profile latticed strip. The blind includes a bracket, several thin blades arranged under the bracket with threading holes, a blade regulator, and at least two narrow shaped and thin profile latticed strips extending from the bottom of the bracket. The strips each include a front and a rear strip body as well as a blade span connected transversely between front and rear strip bodies. The front and rear strip bodies are positioned correspondingly to the threading hole of the thin blade. When the thin blade is adjusted to a vertical light-shading angle, the threading hole of the thin blade can be fully blocked by the front and rear strip bodies. Due to the thin-profile structure of the latticed strip, when the thin blades are superimposed, a compact spacing among the thin blades can be kept.

Abstract: The grid strip component for shutters with pull cords includes a grid strip having two vertical strips that are spaced vertically with certain length set aside, and between the two vertical strips are several horizontal strips, and on both sides of the vertical strips are several pull cord loops. There are two pull cords, which are to go through several pull cord loops that are on the outsides of the vertical strips; moreover, the length of at least one end of the two pull cords should be extra long, and this extra length is the length needed to install the shutters; and by so doing, the grid strip of the present invention uses the unique pull cord to make the assembly more convenient and more effective.
