Abstract
A folding blind, consisting principally of a fixed top and bottom beam, and also a parallel thereto slidable along cords intermediate beam to which a panel of pleated material is fastened, whereby the intermediate beam is divided into a first and a second intermediate beam, in which the second intermediate beam is slidable along cords parallel to or with the first one, so being able to provide on the one side a composite folding blind which consists of more than one folding blind, linked above one another or on the other side a panel of material to be fitted between the fixed top and bottom beam and the first and second intermediate beam respectively, so producing in effect two folding blinds.
Claims17
A folding blind comprising first and second main beams disposed in generally parallel relation, the two main beams being fixed relative to each other to define a space of fixed area therebetween, first intermediate beam means and second intermediate beam means, the two intermediate beam means being disposed between the main beams in generally parallel relation to each other and to the main beams, cord means tensioned between said main beams in slidable, frictional engagement with said first and second intermediate beam means for guiding said intermediate beam means between positions of relative displacement therebetween, and pleated panel means responsive to positioning of said intermediate beam means for defining at least one blinding space of variable area within said space of fixed area.
A folding blind assembly fitted within a window opening and comprising first hollow main beam means and second hollow main beam means delineating opposite ends of the window opening and defining the window viewing space therebetween, first hollow intermediate beam means and second hollow intermediate beam means, the two intermediate beam means being disposed between the main beam means in generally parallel relation to each other and to the main beam means so that opposite ends of all of the beam means are in alignment to define opposite side spaces at opposite sides of the window opening through which light may penetrate even in the presence of a blinding panel, accordion pleated panel means extending between at least one pair of beam means and responsive to movements between such pair of beam means to define a blinding space of variable area within said window opening, cord means tensioned between said main beam means and passing in slidable, frictional engagement through said beam means for guiding said intermediate beam means between positions of relative displacement therebetween and for defining flights of such cord means at the ends of said pair of beam means which are disposed within said opposite side spaces to clear said panel means.
A folding blind comprising a fixed top beam and a fixed bottom beam defining a sight area therebetween, cord means connected between the top and bottom beams, a pair of spaced apart relatively movable intermediate beam means disposed between the top and bottom beams and guided on the cord means for movements between widely spaced, parallel positions adjacent the respective top and bottom beams and closely spaced positions relative to each other, and pleated panel means connected to the pair of intermediate beam means for expansion and contraction in response to parallel movements between the pair of intermediate beam means to block off more or less of the sight area.
