Abstract: A solar-shading assembly for fastening to a support mullion, comprises an elongate louver member having longitudinal front and rear edges, an elongate cap element for extending along and covering the rear edge, a bracket which is connectable to the support mullion, and a fastening device for connecting the bracket to the rear edge of the louver member. The in use fastening device is coverable by the cap element so as to hide the fastening device from view. Preferably, at least part of the bracket is also coverable by the cap element so as to hide the said part of the bracket from view.

Abstract: A roller blind mechanism 16 for winding and unwinding a rollable blind, comprises a support element 18, a drive sprocket 20 which is rotatably mounted on the support element 18 for transmitting rotational movement to a blind supporting member, and a manually-movable elongate flexible drive element 22 which includes a plurality of interlinked tooth-engaging elements 32. The drive sprocket 20 includes a plurality of flexible teeth 38 engagable with the tooth-engaging elements 32 of the flexible drive element 22.

Abstract: A clutch mechanism for a roller blind, comprises a housing, a drive member journalled for rotation within the housing, a hub portion projecting from the front of the housing, a C-shaped leaf spring, which has in-turned ends, mounted in the hub portion for frictional engagement with the internal wall of the hub portion, a boss rotatable with the drive member and extending within the C-shaped spring so that rotation of the boss by the drive member causes the spring to close slightly thereby reducing the frictional engagement between the spring and the hub, and a driven member rotatably mounted on the hub for operating the roller blind. The driven member has a lug which projects into the space between the ends of the C-shaped spring so that any tendency to rotate the driven member by the weight of a partly lowered blind causes the C-shaped spring to open slightly and increase its frictional engagement with the hub.

Abstract: A solar shading louvre comprises two spaced light transmissible sheets, a light transmissible redirecting layer positioned between the light transmissible sheets, and a cured cold pour resin by which the light transmissible redirecting layer is fixed relative to the light transmissible sheets. The cold pour resin includes an inhibitor that prevents or inhibits an adverse reaction between the cold pour resin and the light transmissible redirecting layer. Solar shading incorporating the louvre and a method are also provided.

Abstract: Apparatus for attaching items such as solar shading to curtain walling mullions of the kind defined, comprises a bracket having a generally U-shaped formation at one end for fitting over the generally U-shaped formation of the glazing bar of a mullion, a substantially planar portion which, when the bracket is fixed to the mullion, projects forwardly of the glazing bar and in use between two adjacent glazing units and a seal locating formation projecting laterally of the substantially planar portion. The generally U-shaped formation comprises a web portion and two parallel or substantially parallel side portions. The web portion has an aperture therein above and/or below the substantially planar portion for receiving a self-tapping screw which can, in use, extend through the aperture and engage with the groove in the U-shaped formation of the glazing bar.
