Abstract: An apparatus for retaining a blind comprises: a first elongate element for attachment to a supporting structure; a second elongate element attachable to the first elongate element, in order to at least partially form a guide track providing a guide channel in which a part to be guided may be constrained, the first and second elements together at least partially defining the external surfaces of the guide track. The second elongate element is attachable to the first elongate element by displacement of the second element relative to the first element. The direction of displacement may be a direction substantially transverse to the direction of elongation of the first element.

Abstract: A roller assembly for a horizontally opening retractable screen has a flexible screen with upper and lower toothed edges. Upper and lower guide tracks each have an elongate retaining channel in which an upper and lower edge of the flexible screen is received. The assembly comprises a roller onto which the flexible screen is rolled when the screen is open and from which the flexible screen is unrolled. A guide arrangement is associated with the lower end of the roller that guides the lower toothed edge of the screen into the elongate retaining channel of the lower guide track. The guide arrangement defines a guide passage having an exit aperture through which the lower toothed edge passes during unrolling that communicates with the lower guide track retaining channel, wherein the toothed edge is retained from being pulled out of the exit aperture as it passes therethrough.

Abstract: A retractable screen for extending across an architectural opening is disclosed. The retractable screen includes a fixed side having a fixed screen post; a displaceable handle post having an upper region and a lower region, the displaceable handle post is displaceable away from the fixed side towards a closed position, and is displaceable towards the fixed side back into an open position; at least one of an upper guide track and a lower guide track which is operatively engaged with the upper or lower region of the handle post and guides movement of the handle post between the open and closed positions.
