A multisectional blind and solar collector combination device for combined window covering and solar collection includes a housing with a back face that comprises a fixed solar panel. A power module is coupled to and positioned in the housing. The power module is operationally coupled to the fixed solar panel. A plurality of slats is positioned in a plurality of sections. The slats of each section are coupled to a respective horizontal support. The horizontal supports are coupled to a bottom of the housing in a tiered formation.

A multi-partition blind system include a system of mechanisms that cause slats on a covering for an architectural opening to be partitioned into multiple operational sections. Partitions may be created to the extent of controlling each individual slat. Various embodiments and mechanisms are used to control, stabilize, and cause the opening and closing movement of one group of partitioned slats independent of others or individual slats independent of others.

Embodiments generally relate to a screening element, screen assembly, and associated fixing systems, components and methods. Such embodiments can be used for exterior protection of windows and/or building facades, particularly in commercial buildings and the like. Some embodiments relate to a lightweight screening element, awning or louvre blade that can be readily fixed and applied to the exterior of buildings or built structures so as to provide a screen. Some embodiments relate to a screening element, comprising: an elongate panel defining a first portion and a second portion angled relative to the first portion; and at least one solar panel connected to the first portion of the elongate panel.

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.

A multi-mode up-down curtain includes a winding component, a cord fabric, an adjusting rod, a positioning element and a falling element. The winding component includes a support element and a roller rotatably mounted there on. The cord fabric is entirely or partially wound around the roller. The cord fabric includes a light-transmitting section and a light-tight section which are connected along a stretching direction of the cord fabric. The light-tight section is arranged in front of the light-transmitting section along the stretching direction. The adjusting rod is connected to the light-tight section, and the adjusting rod is spaced apart from the light-transmitting section along the stretching direction. The light-tight section is located between a junction and the falling element, while the light-transmitting section is located between a top edge of a window and the junction, therefore a part of outdoor natural light can enter a room.

A screening element, screen assembly, and association fixing systems, components and methods are provided, that can be used for exterior protection of windows and/or building facades, particular in commercial buildings and the like. A lightweight screening element, awning or louvre blade that can be readily fixed and applied to the exterior of buildings or built structures so as to provide a screen are is provided. The screening element includes an elongate panel defining a first portion and a second portion angled relative to the first portion, and at least one solar panel connected to the first portion of the elongate panel.

A window covering system and a calibration method therefor are provided for generating a safe distance between a middle rail and a lower rail according to status of a first lifting cord. The calibration method includes moving the middle and lower rails upwardly until reaching their initial positions, moving down the lower rail a predetermined distance and storing the detected position thereof as a first position, moving down the middle rail until a switch transmits a first signal as the first lifting cord running through the switch becomes loose, moving up the middle rail until the switch stops transmitting the first signal as the first lifting cord becomes tense, storing the detected position of the middle rail as a second position, and generating the safe distance according to the first and the second positions such that the middle rail is prevented from being pushed by the lower rail.

A system for adjusting a skewed rail in a window covering includes first and second spools to allow first and second lift cords, respectively, to be wound around and unwound from the respective spools. The system also includes a lift rod coupled between the first and second spools and a skew adjustment assembly configured to adjust the first spool between an engaged state, in which the first spool is rotationally engaged with the lift rod such that the first and second spools rotate together, and a disengaged state, in which the first spool is rotationally disengaged from the lift rod to allow the first spool to be rotated relative to the second spool. When in the disengaged state, rotation of the first spool relative to the second spool adjusts an effective length of the first lift cord relative to the second lift cord.

A serial type multi roll blind is provided. The serial type multi roll blind includes: a weight bar, a first screen that has a lower end connected to the weight bar and an upper end connected to a first winding roll and is wound on the first winding roll or unwound from the first winding roll by rotation of the first winding roll, a first winding bar in which the first winding roll is rotatably coupled, a second screen that has a lower end connected to the first winding bar and an upper end connected to a second winding roll and is wound on the second winding roll or unwound from the second winding roll by rotation of the second winding roll, and a first winding bar in which the first winding roll is rotatably coupled.
