ABSTRACT:
A width adjustable Venetian blind that is extendible within limits. The blind includes a telescopic head channel assembly, a telescopic tilt rod assembly, a slat assembly, and a telescopic bottom rail assembly. The head channel assembly includes a central channel and sliding right and left channels. The tilt rod assembly includes a tilt rod body, two sliding tilt rod extensions, and two retaining clips to retain it in the head channel assembly. The slat assembly includes a series of vertically spaced slats. Each slat includes two slat components that overlap each other and are slidably secured to each other by two slat clips. The bottom rail assembly includes a bottom rail body and two sliding bottom rail extensions. At least three axially spaced ladder drum assemblies encircle a portion of the tilt rod assembly with at least three ladders depending therefrom. Each ladder supports the slats on its rungs. The bottom rail assembly is connected to the ends of the ladders. The blind is installed within two support brackets, which have an entrance in one of their sides. After right and left channels of the head channel assembly are extended into the support brackets, a locking tab tip is inserted into a hole in the right and left channels to secure them to the central channel. The extension of the head channel assembly causes the corresponding extension of the tilt rod, slat, and the bottom rail assemblies.
