Abstract: A louver roller mechanism is described herein. The louver roller mechanism comprises a turning cylinder in which at least one roller is mounted, a turning cylinder cover is mounted at the opening of the turning cylinder, the turning cylinder and the turning cylinder cover are sequentially and axially mounted on a rotating shaft, and a square shaft is mounted in the rotating shaft. A roller system consisting of a roller mechanism and a gear clutch turning mechanism is also described, which comprises a base and a top cover. The roller mechanism and the gear clutch turning mechanism are set on the base, the roller mechanism is wound with ladder tapes, the roller mechanism is in axial connection with the gear clutch turning mechanism, and the roller mechanism and the gear clutch turning mechanism are driven to rotate by the square shaft.

Abstract: The invention discloses a louver roller system with a cam pin turning mechanism, including a base and a top cover, wherein a roller mechanism and a cam pin turning mechanism are mounted on the base, the roller mechanism is wound with ladder tapes, the roller mechanism is in axial connection with the cam pin turning mechanism, and the roller mechanism and the cam pin turning mechanism are driven to rotate by a square shaft. The roller mechanism controls horizontal rising and falling of secondary louver blades, and the roller within the roller mechanism rotates to wind or unwind the ladder tapes thereon and sequentially drives various secondary louver blades to rise and fall horizontally. When various secondary louver blades rise to a predetermined position, the roller drives the cam pin turning mechanism to bring a turning cylinder to rotate, so as to achieve turning of all louver blades.

Abstract: The present invention discloses a sequential control roller system for a variable pitch shutter. The system comprises a lifting device for controlling the overall lifting and switchover of all blades and a blade separating/shutting and turnover device for controlling the lifting of the blades relative to each other and the overall turnover of the blades. The lifting device is in transmission connection to the blade separating/shutting and turnover device. The lifting device comprises: a planetary gear clutch capable of controlling the retraction and extension of a lifting rope for realizing the overall fitting of all blades and capable of providing power to the blade separating/shutting and turnover device; and a switching slider mechanism for switching the working state of the planetary gear clutch. The blade separating/shutting and turnover device comprises a number of blade turnover drums and blade translation control rollers.

Abstract: A multi-slat combination blind of rotation type, that includes a main slat (1) and rotating slat(s) (2). The main slat (1) is composed of a outside part (11) and a inside part (12). A joint section is the edge of the outside part meets the inside part at the width direction. The included angle between the outside part and the horizontal plane is ?1, and the included angle between the inside part and the horizontal plane is ?2. The rotating slat is hinged on the main slat, which is driven by the mechanism system. The blind of present invention can block and guide sunlight according to different seasons and personalized requirements.

Abstract: The disclosed is a multi-slat combination blind of rotation type that includes a main slat (1) and rotating slat(s) (2). The main slat (1) is composed of a outside part (11) and a inside part (12). A joint section is the edge of the outside part meets the inside part at the width direction. The included angle between the outside part and the horizontal plane is ?1, and the included angle between the inside part and the horizontal plane is ?2. The rotating slat is hinged above the main slat, which is driven by the mechanism system. In this invention, all kinds of blinds—sun-shading and light-guiding system composed of any V-shaped rotating multi-slat, can optimize blocking and guiding sunlight according to different seasons and personalized requirements, can fit different demands for sunlight in summer and winter, can keep high transmission either with high or low solar elevation angle to satisfy people's visual needs—good view through window.

Abstract: The disclosed is a multi-slat combination blind of up-down-movement type which includes a main slat (1) and a lifting slat (2). The cross section of the lifting slat (2) in the width direction has the same shape as that of the main slat (1) in the width direction. The lifting slat (2) is attached on the upper or lower surface of the main slat (1). The lifting slat (2) can be driven to lift together with the main slat (1) and also to lift relative to the main slat (1) by a lifting mechanism. Various sun-shading and light-guiding blind systems formed by the multi-slat combination bind of up-down-movement type can achieve the optimization of controlling retro-reflection and guiding volume of direct sunlight according to season change and specific requirements of persons. High transparency is simultaneously kept whether solar elevation angle is high or low.
