The present invention relates to a safety blind that operates without a cord. More specifically, there is no danger of safety accidents because a lifting cord inserted into a fabric tube of a leather cord is not exposed to the outside, the lifting and tilting operation of an entire slat can be easily and simply performed by operating a lower slat, and a driving unit can be applied to Venetian blinds, roll blinds, and various blinds.

The present invention relates to a blind for solar photovoltaic power generation including blind blades each having solar cell panels installed on one side thereof to enable solar photovoltaic power generation. In the blind of the present invention, solar cell panels are provided in a prefabricated form, allowing the solar cell panels to be replaced and repaired individually.

The blind 1 for solar photovoltaic power generation according to the present invention includes a fixing frame 100 fixed to a ceiling or a window frame; and a plurality of blind blades 200 installed under the fixing frame 100 so as to be spaced apart from each other. In this case, a plurality of solar cell panels 220 is mounted on one surface of each of the blind blades 200.

The present invention relates to a blind blade assembly for solar photovoltaic power generation including solar cells installed on one side thereof to enable solar photovoltaic power generation. In the blind blade assembly of the present invention, solar cells are provided in a prefabricated form, allowing the solar cells to be replaced and repaired individually.

The blind blade assembly for solar photovoltaic power generation according to the present invention includes a blade frame 210 provided with a mounting groove 211; a plurality of solar cell panels 220 disposed in the longitudinal direction in the mounting groove 211; and fixing members 230 for connecting electrodes 223 between the solar cell panels 220 and for fixing seams.

The disclosure provides roll-up coverings for an architectural opening, and various embodiments of ladder tapes. Embodiments of the roll-up covering include a roller, a first outer elongate tape, a first inner elongate tape and a plurality of slats disposed between the outer and inner elongate tapes. The first inner elongate tape can further defines a plurality of collapsible hinge segments disposed along the length of the first inner elongate tape. The collapsible hinge segments can be configured to collapse in order to decrease the effective length of the first inner elongate tape when the first inner elongate tape is rolled up around the roller. The collapsible hinge segments can further be configured to expand in order to increase the effective length of the first inner elongate tape when the roll-up covering is unrolled from the roller.

Venetian blind with slats elongated in a horizontal direction, suspended via and evenly distributed along flexible strings provided with stoppers permanently fixed to the strings in positions at a uniform pitch between each pair of successive stoppers. The stoppers and the openings in the slats are dimensioned such that the flexible strings with the stoppers thereon can be threaded through the openings in the slats. In operative condition, each slat is supported by supports and each support is carried by one of the stoppers. During assembly the strings with the stoppers are threaded through the openings, then the supports are arranged so as to be supported by the stoppers and support the slats relative to the stoppers.

A retractable cover for architectural openings having collapsible vanes includes a support structure in the form of a sheet of material, monofilaments, tapes, ribbons, cords, or the like, supporting an upper edge of a plurality of vertically spaced, horizontally extending vanes with the lower edges of the vanes in most embodiments of the invention being connected to operating elements adapted to raise the lower edges of each vane toward the upper edges to define openings or gaps between the vanes through which vision and light can pass in an open condition of the covering. Variations of the covering do not require movement of a lower edge of a vane relative to an upper edge but simply movement of some vanes relative to other vanes. The vanes can be made of materials having different flexibilities and where more rigid materials are used, creased fold lines can be established for desired operability.
