  • Patent number: 9797190
    Abstract: The invention discloses a louver roller system with an intermittent gear turning mechanism, comprising a base and a top cover, wherein a roller mechanism and an intermittent gear turning mechanism are mounted on the base, the roller mechanism is wound with ladder tapes, the roller mechanism is in axial connection with the intermittent gear turning mechanism, and the roller mechanism and the intermittent gear 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 intermittent gear turning mechanism drives a turning cylinder to rotate, so as to achieve turning of all louver blades.

  • Patent number: 9580958
    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.

  • Patent number: 9493983
    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.
