ABSTRACT:
A portable roll up window blind has an adjustable length and is removably mountable within the frame of a window. The blind has shell housing of an adjustable length and a telescopic winding core mounted between two end plates of the shell housing. One of the end plate is slidable and adjustable by a wedging means for pressing against the adjacent side wall of the window frame so that the two end plates cooperate with one another to secure the blind at a selected position in the window frame. The window blind panels are wound on the winding core in an overlapping manner. The winding core has one end engage with a round support pin located on the inner surface of the one end plate, and the other end engaged with a rotary shaft having a multi-sided cross sectional shape. The rotary shaft is rotatable by a pull chain for raising or lowering the window blind panels.
