The kit further includes a plurality of mounting parts each having an outer face incorporating a different arrangement of securing formations adapted to be engageable with a respective mounting bracket, and a drive part including (i) a housing adapted to be coupled with any one of the mounting parts and (ii) a drive rotatingly mounted within the housing and adapted to be coupled with any one of the driven parts. ## Claims ### Claim 1 A kit of parts for assembling a control assembly for a roller blind, said kit of parts comprising: a plurality of driven parts each comprising a tubular body, said tubular body of each of said plurality of driven parts having a different diameter and/or profile adapted to be inserted into and drivingly engage a respective roller blind tube; a plurality of mounting parts each having an outer face incorporating a different arrangement of securing formations adapted to be engageable with a respective mounting bracket; and a drive part comprising (i) a housing adapted to be coupled with any one of said mounting parts, and (ii) a drive rotatingly mounted within said housing and adapted to be coupled with any one of said driven parts. ### Claim 2 (depends on 1) The kit of parts of claim 1, further comprising one or more biasing assemblies, said one or more biasing assemblies being adapted to be coupled with at least one of said plurality of driven parts for imparting a rotational biasing force against the respective roller blind tube into which a selected one of said driven parts is inserted. ### Claim 3 (depends on 1) The kit of parts of claim 1, wherein said tubular body of each of said driven parts comprises a cylindrical outer part having an outer surface of a specific diameter and/or incorporating an arrangement of surface formations and/or channels/recesses adapted to engage with the respective roller blind tube of a particular roller blind assembly. ### Claim 4 (depends on 1) The kit of parts of claim 1, wherein each of said driven parts includes a central bore having a diameter and length adapted to receive a central pin extending from a selected one of said mounting parts, said pin including at least one resiliently deformable leg having a length selected to pass through said central bore of the selected one of said driven parts and terminating in an outwardly facing catch adapted to retain said central pin of the selected one of said mounting parts within said central bore of the selected one of said driven parts when assembled. ### Claim 5 (depends on 4) The kit of parts of claim 4, wherein said central pin defines a bush upon which the selected one of said driven parts may be guided and supported for rotation thereon when assembled. ### Claim 6 (depends on 4) The kit of parts of claim 4, wherein said drive part includes a central aperture arranged such that said central pin of the selected one of said mounting parts passes therethrough before passing into said central bore of the selected one of said driven parts, when assembled. ### Claim 7 (depends on 6) The kit of parts of claim 6, wherein the drive of said drive part includes a drive formation adapted to engage the selected one of said driven parts to permit transfer of rotation between the drive of said drive part and the selected one of said driven parts. ### Claim 8 (depends on 7) The kit of parts of claim 7, wherein said drive formation comprises a segment of a tube dimensioned to fit around said central pin of the selected one of said mounting parts and be received within a suitably dimensioned region of said central bore of the selected one of said driven parts to rotatably engage the drive with the selected one of said driven parts when assembled. ### Claim 9 (depends on 1) The kit of parts of claim 1, wherein each of said plurality of mounting parts includes a flange, said housing of said drive part incorporating a recess shaped to receive said flange of any one of said mounting parts therein. ### Claim 10 (depends on 9) The kit of parts of claim 9, wherein said securing formations are formed on an outer face of said flange of at least one of said plurality of mounting parts. ### Claim 11 (depends on 9) The kit of parts of claim 9, wherein at least one of said plurality of mounting parts is formed from first and second parts, said first part including said flange and said second part abutting an outer face of said flange of said first part, an outer face of said second part incorporating said securing formations thereon. ### Claim 12 (depends on 11) The kit of parts of claim 11, wherein said second part incorporates a locating pin receivable within an aperture within said first part, said locating pin including one or more outwardly facing resilient retaining catches or claws adapted to secure said first part to said second part. ### Claim 13 (depends on 9) The kit of parts of claim 9, wherein an inner face of said flange is provided with projections or other formations arranged to engage said housing of said drive part, when assembled, to prevent rotation between the selected one of said mounting parts and said housing of said drive part. ### Claim 14 A method of assembling a control assembly for a roller blind, said method comprising: selecting a driven part from a plurality of driven parts each comprising a tubular body, the tubular body of each of the plurality of driven parts having a different diameter and/or profile adapted to be inserted into and drivingly engage a respective roller blind tube; selecting a mounting part from a plurality of mounting parts each having an outer face incorporating a different arrangement of securing formations adapted to be engageable with a respective mounting bracket; and coupling the selected driven part and the selected mounting part with a drive part, the drive part comprising (i) a housing adapted to be coupled to any one of the mounting parts, and (ii) a drive rotatingly mounted within the housing and adapted to be coupled with any one of the driven parts.
