Abstract: A retractable blind or shade assembly for covering a polygonal contoured surface area, includes a retractable covering member (2, 16, 36, 37, 55), a movable member (3, 39, 60') and at least one cord member (9, 43, 44, 58). At least one cord member (9, 43, 44, 58) is provided between its terminal ends with a looped connection (10, 10') adapted to engage the movable member (3, 39, 60') upon a predetermined amount of relative movement between the movable member (3, 39, 60') and the one cord member (9, 43, 44, 58) in one direction, while otherwise relative movement between the movable member (3, 39, 60') and the cord member (9, 43, 44, 58) is independent of one another. The assembly enables the engagement of a further element without obstruction to being guided through openings or around deflecting surfaces and pulley wheels, such as are often part of a blind or shade structure.

Abstract: A tensioning, releasable mounting device (9) for a window covering structure mountable in a window recess (R) and including spaced apart beams (3, 4) supporting one or more tensioned cords (2) supporting and guiding a covering panel (1). The mounting device is mounted on each end of at least one beam, and is moveable between an active position, in which each cord (2) is tensioned, and a second position in which each cord (2) is slackened, so that the window covering is easily removed from the window recess.

Abstract: An apparatus for suspending lamellar sun-blinds or the like, which apparatus comprises a profile open on at least one side with guiding, wherein a number of carriers (5) each having a gear transmission (8) and movable along the guiding by means of a control means, a control rod (11) arranged rotatably in and parallel to the profile, which is carried in each case through one of the gears of the transmission (8), a vertical rotating pin (7) with depending member for the slat connected to another gear and supported by the carrier, a spacer strip (66) connected to each of the carriers (5) which is guided slidably in a guiding of the adjacent carrier, wherein the spacer strip (66) is fixed on the side of the carrier such that the blade of the strip is vertically oriented in order to provide a profile dimensioning that is aesthetically well-considered, requires small dimensions particularly in the height and is thereby easy to combine with other profiles for additional applications.

Abstract: In order in a device for internal shading of triangular, trapezoidal, polygonal or semicircular glass areas with a foldable or gatherable hanging means or drape, the hanging edge of which displaceable for the closure and opening is equipped with a profile strip and the side edges of which adjoining the displaceable hanging means edge are guided on holding means, to make available a completely novel constructional concept which is able to cover with simple construction a great number of complicated and possibly irregular area forms both for vertical and for inclined or possibly horizontal glass areas, the profile strip is divided into two or more strip portions (6, 7) which are articulately connected to each other.

Abstract: A device for transmitting a drive force between a flexible element, such as cord, and a first rotatable, cylindrical body, said flexible element is trained around the casing surface of the body through a pre-determined angle, wherein a second cylindrical body is arranged with a rotating shaft parallel to that of the first, along which the flexible element is trained in opposing direction, said both bodies, preferably provided with at least one groove for receiving said flexible element, are embodied and/or placed such that the bodies rotate without slippage between flexible element and both cylindrical bodies.

Abstract: An electromotively driven sunblind includes a first beam and a second beam which are movable in parallel relative to each other. A motor and a drive shaft having at least one drive roller are disposed within a hollow cavity in the first beam and relative movement of the second beam is effected by at least one flexible operating element. A screen is disposed between the first beam and the second beam which may be of a pleated material.
