Abstract: A roller tube comprising a tube body which defines on its outwardly facing surface one or more blind substrate or shutter substrate receiving portions, wherein the tube body includes a plurality of sound damping elements located circumferentially around its inwardly facing surface, the sound damping elements extending longitudinally along at least part of the length of the tube body and defining a plurality of sound channels inside the tube.

Abstract: A roller blind including a sheet element secured at one end to a roller tube mounted for rotation, and secured at its opposite end to a fixed element located adjacent to the roller tube such that the sheet element defines a return portion located between the two ends; and a roller blind bottom bar located within the return portion, wherein the roller blind bottom bar includes a tubular body and an end cap carried by each end of the tubular body, the end caps including a proximal portion located adjacent to the tubular body, a distal portion spaced from the tubular body, and an outwardly flared portion located between the proximal and distal portions such that the end cap flares outwards from the proximal portion to the distal portion.

Abstract: The present invention relates to a roller blind idle end assembly for roller blinds comprising a splined bush, a support bearing and an end pin, wherein the splined bush is supported by the support bearing and rotatable relative thereto in use; the end pin projects from the support bearing and is slidably coupled thereto such that the end pin is adapted to move axially relative to the support bearing and projects therefrom to engage with a receiving element of a mounting bracket; and wherein the end pin is rotationally fixed relative to the support bearing. This assembly reduces wear between an idle end pin and an idle end bracket and the likelihood of failure of the blind.

Abstract: A chain guard housing for a blind, the housing including a body portion and a chain cover portion hingedly coupled to the body portion, whereby the chain cover portion is capable of being rotated about the hinge out of alignment with a chain sprocket.

Abstract: A roller blind coupling (101) for use in coupling a pair of adjacent roller blinds (102, 104) which are angled relative to each other, the coupling (101) including a first splined bush (2) adapted to engage a first roller tube (106), a second splined bush (4) adapted to engage a second roller tube (108) and a flexible shaft (6), wherein the flexible shaft (6) includes a first connector which engages the first splined bush (2) and a second connector (20) which engages the second splined bush (4), whereby the flexible shaft (6) connects the first and second splined (2, 4) bushes and rotation of the first splined bush (2) is transmitted to the second splined bush (4) via the flexible shaft (6).

Abstract: A spring assembly for a roller blind, the assembly including a stationary end, a rotatable end and a spring arrangement located therebetween which is connected at a first end thereof to the stationary end and at a second end thereof to the rotatable end, wherein the rotatable end includes a rotatable body which is adapted to rotate relative to a fixed body about a rotational axis, and wherein the spring assembly further includes a locking pin coupled to the fixed body such that it has a locked configuration in which it engages a portion of the rotatable body and prevents rotation of the rotatable body relative to the fixed body and a free configuration in which rotation of the rotatable body relative to the fixed body is permitted.

Abstract: A fabric receiving element for a blind assembly, the fabric receiving element having at least two axially extending slots, each slot defining an opening for receiving blind material, the openings being of different respective widths, the slots including a floor opposite the openings, and wherein the middle portion of the floor of the slot is at a greater distance from the opening than the end portions of the floor of the slot.

Abstract: A window blind frame system is provided comprising a window blind secured to a frame and optionally at least one frame-securing clip for releasably retaining the frame in position relative to the window casing. The frame may comprise at least two angle joints connecting at least three extruded portions to form a substantially rigid structure, wherein a window blind may be attached to the frame and wherein the frame is configured to interact with a frame-securing clip which releasably retains the frame in position relative to a window casing. The components of the window blind frame system may be provided in kit form. Methods of assembly and fitting of the window blind frame system are also provided.

Abstract: A shim for reducing play between a roller blind tube and a roller blind end plug, the shim including a rib receiving portion sized and configured to receive a rib from a roller blind tube, wherein the shim is capable of being located between adjacent splines of a roller blind end plug.

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 center-pin engages an external surface of the control unit. In addition, a releasably inter-engaging combination of this plug and center-pin wherein insertion of the center-pin through a roller blind control unit and engagement with the plug, ensures that a tip of the center-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 center-pin, and a plug for releasable engagement with the center-pin.

Abstract: A window blind assembly is provided for use with a roller blind. The assembly comprises a charging element; a retaining element; and an energy storage system operatively connected therebetween. The energy storage system comprises a plurality of springs and the charging system is adapted to rotate relative to the retaining element such that the energy storage system is charged upon closure of the blind and the stored energy is released during the opening of the blind, whereby the opening of the blind is assisted by the release of the stored energy from the energy storage system. The springs are connected in series such that they are axially spaced from each other and adjacent ends of the springs are connected together via a connector located therebetween, wherein the adjacent ends of the springs are each coupled to a respective end of the connector and rotation of one spring relative to the other is prevented.
