The present invention relates to a blind-type curtain and particularly, to a blind-type curtain capable of allowing curtain blinds to be individually separated and washed or replaced and allowing a light-transmitting state and a blackout state to be easily controlled since a plurality of curtain blinds are connected to each other by a connector, and allowing the curtain blinds to easily form a “U” shape since an extension plate is formed. The present invention can increase aesthetics by fastening adjacent blackout curtain parts through the connector. In addition, the present invention enables light transmittance in the curtain state, and can use a blackout curtain effect by using rotation (the angle control of verticals) when adjacent blackout curtain parts are fastened through a connector. Additionally, the present invention facilitates individual washing and repair due to contamination or damage since a plurality of curtain blinds can be individually separated. Furthermore, the present invention can promote an aesthetic appeal since the curtain blind comprises a weight at the lower end thereof, thereby allowing the curtain blind to be tightly pulled. Moreover, the present invention can promote an aesthetic appeal by allowing the color and the pattern of curtain blinds to be different since a plurality of curtain blinds can be individually separated. The present invention can provide a blind-type curtain having a perfect “U” shape since the extension plate for supporting a light-transmitting curtain part is formed at the connector.

The invention relates to a double articulated device and system comprising at least one active element provided with an edge (M), with two points (M1) and (M2), where (M1) is different from (M2), a rotating element connected to the edge (M) and a rotating fixture positioned in the point (M1) of the edge (M) and connected to the rotating element, in which, during actuation, the active element simultaneously describes a rotational movement with an angle β around the rotating element, and a partial pivoting movement in the vertical plane around the rotating fixture, so that the point (M2) of the edge (M) describes an angle a between a value α.sub.max corresponding to the “open” position ES0 and a value α.sub.min which corresponds to an ES1 “closed” position of the device.

A solar shading device includes a head rail that slidably supports leading runners having fabric curtains attached thereto, a carrying mechanism that includes a carrying pulley coupled to the leading runners through a belt and carries the leading runners along the head rail on the basis of the rotation of the carrying pulley, a manual drive unit that includes a first shaft coupled to the carrying pulley and serving as a drive shaft, and a suspension part having the manual drive unit suspended therefrom with the carrying pulley and the first shaft coupled together. Further, with the manual drive unit detached from the suspension part, the suspension part allows an electric drive unit to be suspended therefrom with the carrying pulley and a second shaft coupled together, the electric drive unit including the second shaft as a drive shaft for driving the carrying pulley.

A blind co-used sheet includes a vertical first blind sheet, a vertical second blind sheet, transverse double-layered blind sheets sown between the first and second blind sheets and fixing plate assemblies for securely holding front ends of the transverse double-layered blind sheets. The transverse double-layered blind sheets can be turned from a transverse state into a vertical state and used as a vertical blind. Alternatively, the transverse double-layered blind sheets can be 90-degree turned back from the vertical state into the transverse state and used as a Shangri-la blind. Two sides of the transverse double-layered blind sheet have upward and downward extending sunshade sections, which can overlap each other. A sunshade sheet is disposed in the transverse double-layered blind sheet to locate the blind sheets.

A vertical curtain blind includes a panel assembly having a plurality of individual panels coupled together in a side-by-side arrangement. Each panel extends in a vertical direction between a top end and a bottom end. Additionally, each panel includes first and second pockets positioned along first and second sides of the panel, respectively, adjacent to the top end of the panel. The blind associated includes a plurality of clip assemblies, with each clip assembly being configured to couple a respective pair of adjacent panels of the plurality of panels together. Each clip assembly includes a first connector clip positioned within the first pocket of a first panel of the respective pair of adjacent panels and a second connector clip positioned within the second pocket of an adjacent second panel of the respective pair of adjacent panels, with the first connector clip configured to be coupled to the second connector clip.

A covering for an architectural opening has a dual cord operating system. The covering may include a head rail, blind panels depending from the head rail, and an operating system. The operating system may include a housing connected to the head rail, a first drive assembly rotatably mounted within the housing and operable to move the blind panels between an extended configuration and a retracted configuration, and a second drive assembly rotatably mounted within the housing and operable to move the blind panels between a closed configuration and an open configuration.

A vertical blind structure has: an upper track, at least one track set and a plurality of blades. The upper track with an adjustable length has an inner track and an outer track, and the inner track and the outer track are disposed on a same side and connected to each other with a connecting track. The inner and outer tracks of the upper track respectively have an engaging portion and further have a plurality of clamping members. The at least one track set has a plurality of sliding tracks parallel with each other, and each sliding track has a positioning groove and a corresponding limiting groove at two opposite sides and a storing groove at a bottom side. An end of each positioning groove of the sliding track comprises a sliding block.
