Abstract: A sun blind for a window, in particular a window occupying permanently or temporarily a slanting position and optionally being operative to be toppled about a horizontal axis, said sun blind comprising a horizontal profiled top bar fastened to or integrated with the header of the window frame, a horizontal profiled bottom bar operative to be moved with respect to said top bar, a sun blinding portion between said top bar and said bottom bar, lateral guides for guiding the ends of the bottom bar, said guides being provided along or within the side posts of the window frame, at least two cords running through apertures in the sun blinding portion and optionally an additional profiled bar along the bottom sill part of the window frame, whereby said cords serve solely for guiding the bottom bar and the sun blinding portion, while the ends of all cords are fastened to fixed points of the top bar, the bottom bar or the lateral guides of the sun blind.

Abstract: A locking device for cords of a sun-blind or the like having an upper beam and one or more webs of sun-blinding material connected thereto. The cords extend through the internal space of the upper beam and leave it for opening or closing the sun-blind. The locking device consists of a U-shaped portion in the legs of which a tumbler is pivotably supported at the one end. The free end of the tumbler is biased in the direction of the bottom of the U-shaped portion. The cords extend between the free end of the tumbler and the bottom of the U-shaped portion and are locked when they are clamped between said free end and bottom resulting from the bias force.

Abstract: A locking device for cords to hold a pleated shade or a venetian blind at a selected elevation comprises a U-shaped channel member and a housing covering one end of the channel member. A cradle integral with the channel member supports an axle on which congruent U-shaped cord-locking members are pivoted. The inner cord-locking member has a slotted bottom portion through which the cord extends to be gripped by the outer cord-locking member when the cord is pulled in one direction by the shade or blind, the cord-locking members releasing the cord in response to reverse tension. The cord is threaded through an opening in the bottom of the channel member and through the cord-locking members before assembly of the channel member and the housing together. The channel member and the housing have interlocking means to hold them attached to each other after assembly.
