Abstract: The invention relates to a plug for releasable engagement with the centre-pin of a roller blind control unit wherein engagement of the plug with the pin ensures that a tip of the centre-pin engages an external surface of the control unit. In addition, a releasably inter-engaging combination of this plug and centre-pin wherein insertion of the centre-pin through a roller blind control unit and engagement with the plug, ensures that a tip of the centre-pin engages an external surface of the control unit is described. The invention also relates to a control unit for use in a window blind head rail assembly comprising: a sprocket wheel, a sprocket support and wrap spring, a splined bush for engagement with a roller blind tube, a centre-pin, and a plug for releasable engagement with the centre-pin.

Abstract: A control unit for use in a window blind head rail assembly including a system of transfer gears coupled to a driving member, the transfer gear system comprising a rotatable inner ring gear; one or more intermediate gears having fixed positions relative to the sprocket support and being rotatable about their own axes; a rotatable outer ring gear connected to a driven member; wherein rotation of the inner ring gear causes rotation of the one or more intermediate gears about their own axes, which causes rotation of the outer ring gear. The driving member has a driving pulley so that force applied to the driving member will cause rotation of the driving pulley and then the gears. A sprocket support and braking means to prevent the control unit from rotating other than in response to force applied via the driving member are also essential as is a splined bush.

Abstract: A Roman blind fabric and a Roman blind made from the fabric. The Roman blind fabric comprising a non-woven web of continuous filaments or microfilaments, the web having a weight in the range 5 g/m2-600 g/m2 and being formed from composite filaments. The fabric includes a plurality of elongate widthwise channels adapted to receive therein respective scaffold elements.

Abstract: A control unit for use in a window blind head rail assembly comprising; a sprocket wheel, a chain guard housing, a sprocket support and wrap spring, a splined bush for engagement with a roller blind tube and a centre pin, wherein the centre pin comprises a centre-pin head and a body, the centre-pin head including one or more fins adapted to co-operatively engage with one or more recesses in the sprocket support.
