A system of blinds comprising louvers that are inclined in such a way as to maximize the direct solar illumination received during the winter months and to minimize same during the summer months is described. The inclinations are determined according to the terrestrial latitude of the building supporting these blinds, and the orientation of the surface of the building that is to be protected. The longitudinal slope of the louvers is determined such that the longitudinal direction of the louvers is substantially parallel to the straight line of intersection of the plane of the surface and the equatorial plane seen from the building. The transverse tilt of the louvers is determined such that these louvers face in a direction comprised between 12° and 24° below the direction of the equatorial plane.

The controller box comprises a body case, a battery, a control board, a motor and a linear bearing, the linear bearing is connected to the motor, a slide rod, which is retractable with respect to the linear bearing, is mounted on the linear bearing, and a rod slot is provided on a side face of the body case. The control board comprises a mainboard, a Hall board and a connection board which are connected in sequence, the Hall board, the connection board and the motor are electrically connected in sequence, and the mainboard is electrically connected to the battery. An interconnecting piece matched with the slide rod is provided on the window shutter, and the slide rod is retractable and slides along the rod slot to control the opening and closing of slats of the window shutter. According to the disclosure, the controller can be used with wireless remote control and mobile APPs to achieve control, which is intelligent and convenient and can greatly reduce the users' labor intensity. It adopts the lithium battery as a power supply and thus is safe and reliable. It is easy for installation and operation without any damage to the window shutter and wall structure and is suitable for self-installation by users.

An expandable shutter assembly for installing shutters in windows of varying widths includes a frame that has a first section slidably engaging a second section such that the frame has an adjustable length. A plurality of shutters is each pivotally coupled to the frame, and the shutters are positionable between an open position and a closed position. Each of the shutters comprises a first portion slidably engaging a second portion such that each of the shutters has an adjustable length to correspond to the length of the frame. A linkage is movably coupled to each of the shutters and the linkage urges each of the shutters between the open position and the closed position.

A shutter is provided. First and second side rails have cavities running in a direction from top to bottom, each cavity having an opening along a lateral side. A plurality of pairs of slat supports are present, each pair having a slat support mounted in the cavity of the first rail and mounted in the cavity of the second rail. Each slat support has a first section and a second section. The first section has a shape to slide into one of the cavities, and to stack and nest with an adjacent first section of another slat support in the one of the cavities. The second section protrudes through the opening of the one of the cavities. A plurality of slats are present, each slat being mounted on the second sections of one of the pairs of slat supports.

A four-device-in-one skybox dehydrator sauna wind-redirecting bungalow comprises: adjustable louver blades attached to side gutter beams for preventing rainwater from getting into the bungalow and adjustably controlling amount of sunlight that shines into the bungalow, chutes formed to the side gutter beams and end gutter beams, solar-rechargeable batteries installed within adjustable louver blades for powering led lights and saving costs of replacing non-rechargeable alkaline batteries and helping reduce carbon footprint, a solar panel mounted to adjustable louver blades for collecting solar energy to charge and recharge rechargeable batteries and saving energy costs associated with lighting the bungalow and saving costs of replacing with non-rechargeable alkaline batteries and providing freedom to place the bungalow away from a power outlet and helping reduce carbon footprint, panel frames, panel inserts inserted within the panel frames for enabling the bungalow to become a sauna and a skybox and a dehydrator and providing security and insulation and protection from wind within the bungalow, louver braces inserted within the panel frames for allowing the louvers to be rotated, flipped, and positioned to redirect wind direction and structuringly securing louvers, axis pins inserted within the louver braces for providing eight locking points to reposition and locking and unlocking and pivotingly functionalizing the louver braces, louvers attached to the louver braces for redirecting and blocking and reducing and sealing the bungalow to create a sauna and a skybox and a dehydrator, an inner-track insert slidably inserted within hook-sliding track for providing a smooth sound-dampening track for slide hooks to be inserted for securing a curtain or insect screen, a curtain removably hooked onto slide hooks for providing privacy and protection from harmful sun rays and wind and insects, an extending-and-retracting door for providing protection from wind and harmful sun rays and insulation from cold temperatures and security within bungalow, door-spool housing attached to door-spool-housing bracket for providing discrete storage and protection of the extending-and-retracting door, drain openings formed into the corner-posts, corner-post-base-plate covers slidably attached onto the corner-posts, corner-post base-plates secured to the corner-posts, sliding-door track attached to the corner-post base-plates, the panel frames interchangably and slidably placed into the sliding-door track, anchoring-screw holes drilled into the corner-post base-plates, and tube-screws screwed into the anchoring-screw holes for leveling bungalow when installed on an uneven ground sur

Described is a louver having a frame that forms an enclosure defining an opening, and a plurality of louver blades disposed within the opening. Each of the plurality of louver blades include a catch member that longitudinally extends between a first blade end and a second blade end of a corresponding louver blade. The louver may also include a rotation assembly configured to rotatably couple with the plurality of louver blades and the frame. The plurality of louver blades may autonomously rotate about rotation members of the rotation assembly based on environmental elements captured in the catch member such that the plurality of louver blades are configured in an open position in response to no water in the catch member and are configured in a closed position in response to an amount of environmental elements in the catch member.

A shutter assembly including a plurality of shutter panels arranged side-by-side. Each shutter panel has a respective plurality of louvers and a respective operable tilt mechanism configured to adjust the tilt angle of the respective plurality of louvers. A control shaft operates the tilt mechanisms. The control shaft is configured to drive simultaneously the respective tilt mechanisms of all of the plurality of shutter panels.

The system includes a series of operable louvers mounted on a four-sided frame and connected on each side to the operating mechanism that allows for easy opening and closing of the louvers. Every part of the system that is exposing to the exterior of the building is separated from the interior part of the system by a low heat conductivity material as a thermal barrier. Each operable louver includes a four-sided main frame, at least one pane of glass and a coupling mechanism on each side that connects to the operating mechanism. The main frame acts as the thermal break as well as a system that absorbs the energy created when an outside object impacts the window from the outside. The system incorporates sealing devices between all moving parts to eliminate water and air infiltration. The operating system allows for easy opening and closing of the window by rotating each louver with the crank mechanism assisted by springs.
