A roll-up control device for a roller shade, comprising a turntable assembly comprising a turntable, a pull spring, an outer turntable, a shaft and a clutch; and a brake assembly comprising a brake shaft cover fastening the shaft rod, a brake spring sleeved on a side of the brake shaft cover, a compression spring expanded and compressed inside the brake shaft cover, a brake sleeve sleeved the side of the brake shaft cover and a shaft housing accommodating a damping ring and clamping the brake sleeve.

A blockout blind system includes side tracks fitted with brushes in conjunction with a pelmet fitted with flaps ensure no light can pass around the blind. The flaps and brushes have offset apertures either side of the blind to allow for airflow thus preventing the blind being sucked out or pushed in by open or leaking windows and air conditioning systems. The system also conceals the chain for operating the blind thus eliminating strangulation hazards for children and animals. The design allows the system to be fitted to existing roller blinds.

The invention relates to a blind assembly, typically for use in conjunction with a window or windows, and a method of installing the blind assembly. The blind assembly is assembled with a sheet material portion and typically actuation means for the selective movement of the sheet material portion, located within a housing. The housing has an opening through which, when the blind assembly is installed, the sheet material portion can be moved between various user selected positions intermediate an extended configuration and retracted configuration. Prior to and during installation, at least the sheet material portion is retained and typically sealed within the housing in the retracted configuration typically by the provision of sealing means which close the opening so as to minimise the risk of damage to the sheet material portion and actuation means within the housing during transit and installation.

A tensioning device comprising a guide adapted to receive thereabout one end of a looped operating element (LOE), a retainer configured to prevent said one end from traveling about the guide, the guide and retainer being configured to move relative one another between first and second positions; a biasing element for biasing the guide towards the retainer to tension the LOE. In the first position, the LOE has no tension and the guide is extended to trap said one end between the guide and the retainer to prevent travel of the LOE about the guide. In the second position, the LOE is tensioned with the guide being retracted from the retainer, and a locking device for locking the guide in the first position when the LOE has no tension such that the guide cannot be retracted away from the retainer to allow operation of the operating element.

An actuation assembly for a continuous looped operator includes a slide assembly configured to laterally slide in a first direction and a second direction opposite the first direction, a first cord engagement member carried by the slide assembly, a second cord engagement member carried by the slide assembly, and a selector switch connected to the slide assembly, the selector switch receives a portion of the first cord engagement member and a portion of the second cord engagement member, the selector switch configured to move relative to the slide assembly between a first position and a second position.

The present invention relates to a combination roller blind wherein a fine adjustment means is provided behind an upper face of a headrail, the adjustment means causing an end of a blind sheet wrapped around a blind roll and an end opposite thereof to be fine-adjustably wrapped and unwrapped. When the blind is installed on a ceiling or a window frame to completely conceal the bottom edge of the window so that a bottom edge of a weight is adjoining a bottom sill of the window frame, and a portion of a light-transmissive section of the blind sheet is not overlapped, the opposite edge wrapped around the blind roll of the blind sheet can be fine-adjusted by rolling so that the light-transmissive section alternates with and is not completely overlapped by a light blocking section, allowing for complete shading to be achieved while completely concealing the bottom edge of the window.

The tensioner is mounted in use to a vertical surface for throughpassage in taut relation of a clutch actuator selected from ball chain and cord and comprises a lock arrangement which: includes a plunger having a bearing surface; and, in use, is adapted to arrest throughpassage of the actuator in slack conditions. The plunger, in use, is: (i) adapted for vertical movement between an extended position and a retracted position that is elevated in relation to the extended position; adapted, when in the retracted position, to receive the actuator in the manner of a pulley, for smooth operation of the shade; and biased for movement towards the extended position. The lock arrangement is adapted, in use: upon movement of the plunger to the extended position, to arrest movement of the plunger towards the retracted position; and, when the plunger is in the extended position, to arrest throughpassage of the actuator.

A window shade apparatus may include a cassette (12), a major tube (36), a minor tube (38), and a bottom bar (14). The bottom bar may include a cover track (432), a tubular rod (434), a bearing insert (436) arranged in the tubular rod, and an end cap (438) connected to the cover track. The end cap may include a circular cylindrical shaft (480) that is telescopically received in the bearing insert. A sheet of flexible material (16) that traverses the tubular rod and forms a proximal sheet between the major tube and the tubular rod and a distal sheet between the minor tube and the tubular rod. A differential adjustment device (46) is disclosed for adjusting the shade. An adjustable stop device (44) is disclosed that regulates the maximum deployment length of flexible material from the major tube.

A blind lifting control module includes a transmitting wheel, an anti-backward unit and a driving unit disposed to a supporting unit. The transmitting wheel for connecting a blind reeled horizontal axle has a wheel ratchet portion meshable with a corresponding reel ratchet portion of a driving reel of the driving unit. The anti-backward unit has a torsion spring operable and deformable relative to the transmitting wheel. A pull cord is reeled on the driving reel and has a free end passing through a thrust member and a hindering member, and is pulled to shift the torsion spring to a released state to permit lowering of a blind. The thrust member is turned by pulling of the pull cord to thrust the driving reel to mesh with the transmitting wheel for lifting the blind.

A curtain rod comprises a main rod, a fixing base and a rotary base. The fixing base and the rotary base are respectively disposed at both ends of the main rod; the main rod comprises a plurality of rod body sections and a connecting member configured to connect two adjacent rod body sections; the connecting member comprises a limiting section and two connecting sections symmetrically arranged on both sides of limiting section; the rod body section is correspondingly provided with a connection cavity for the engagement with the connecting section; shape of the limiting section matches cross-sectional shape of the rod body section; the connecting section is provided with a fixing component for securing rod body section; and side wall of the rod body section is recessed in a direction toward an axis of rod body section to form a fitting section and a avoidance section.
