ABSTRACT:
A Venetian blind structure includes an upper and lower beams made up of telescopically adjustable upper and lower inner/outer brackets respectively wherein a plurality of pull cord and retaining cord mounts are equidistantly adapted at the upper inner/outer brackets therein for a pair of mutually engaged internal and external rods to be mounted thereon, and the internal and external rods thereof have a plurality of adjustment blocks sequentially joined thereto for holding both ends of U-shaped retaining cords thereby. The mutually engaged lower inner/outer brackets are located at the bottommost side of the retaining cords therein, and plural pairs of mutually abutted upper inner and lower outer blind slats are located at retaining holes defined by upper/lower clamping sections distributed equidistantly from top to bottom of the retaining cords thereof. Thus, due to the sleeve engagement of the upper and lower inner/outer brackets and the abutting location of the upper inner and lower outer blind slats thereof, the upper inner bracket and blind slats, and the lower inner bracket thereof can be simultaneously pushed towards the upper outer upper bracket, and the lower outer blind slats and bracket thereof respectively to telescopically adjust and shorten the overall length of the blind thereof, widely fitting to windows of different sizes as well as efficiently cutting down the packing materials required for more economical use of the shipping space to increase the quantity of shipment and the convenience of delivery thereof.
