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.

A window blind includes top and bottom beams, and many slats disposed therebetween. The top beam has two opposite lateral holes. The window blind further includes a slat folding transmission device having a cord rolling member disposed in the top beam, and two opposite lift transmission cords passing through the lateral holes of the lateral plates of the top beam respectively. Two ends of each lift transmission cord are connected with the bottom beam and the cord rolling member respectively, so that the two lift transmission cords can pull the bottom beam simultaneously when being rolled by the cord rolling member, thereby moving the bottom beam upwardly to fold up the slats. Therefore, the slats of the window blind of the invention need no processing and keep complete in structure, thereby providing good effect of blocking out the light when being adjusted to the inclined condition.

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.

A window blind includes an upper beam and a lower beam linked by two ladder-like ropes. The ladder-like rope has a front vertical portion, a rear vertical portion, transverse portions connected between the vertical portions, first ring portions connected to the front vertical portion, second ring portions connected to the rear vertical portion, and third ring portions connected to the front vertical portion. The transverse portion supports a slat from below. The slat has two ends thereof each provided with a through hole and a slot communicated with the through hole. To assemble the slat, the third ring portion of the ladder-like rope has one segment inlaid into the through hole of the slat through the slot, and then the third ring portion is mounted around the front edge of the slat. Also disclosed is a method for assembling the slats of the window blind.

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.

A window blind apparatus for providing solar energy comprises: (a) a case configured for receiving a battery, the case including electrical battery charging circuitry; and, (b) a plurality of photovoltaic panels configured for receiving solar radiation and converting the radiation into electricity, each of the photovoltaic panels in electrical communication with the electrical battery charging circuitry, and, each photovoltaic panel is in communication with at least one other panel, such that the panels are moveable.

A window covering includes a first rail and a plurality of non-moving elements arranged adjacent at least one spring motor positioned in the first rail. The non-moving elements contact at least one lift cord for routing of the lift cord through the first rail to increase friction incurred during motion of the lift cord(s) that takes place during height adjustment of window covering material. Non-moving members can also be positioned to contact at least one lift cord for routing of the lift cord through the first rail to increase friction incurred during motion of the lift cord(s) that takes place during height adjustment of window covering material. The non-moving elements and non-moving members can be positioned in the first rail such that they do not move relative to the first rail when the window covering is mounted and installed for use by a user to adjustably cover a window.
