Novel dimmable shutter

Abstract

The invention relates to a novel dimmable shutter. The novel dimmable shutter comprises a rotating shaft, a whole column of blades connected to the rotating shaft, a decorative section, a balancing weight and a draw cord, wherein at least one movable blade is arranged in the blades and is divided into three sections, namely an overturning blade section and connecting blade sections positioned on two sides of the overturning blade section, adjacent sections are connected through a connecting piece, and the movable blade and connecting piece are together inserted on a thin shaft; the balancing weight vertically moves in the decorative section; one end of the draw cord is fixed to the rotating shaft, and the other end of the draw cord is sequentially connected with all connecting pieces from top to bottom until the balancing weight. When the blades of the shutter are closed, the rotating shaft is continuously rotated, the draw cord drags a connecting piece connected with the draw cord to move upwards, and the overturning blade section is driven to overturn. The novel dimmable shutter is skillful in structural design; the arranged movable blade can be continuously and optionally opened when a window is closed for preventing theft, and the effects of ventilating and the like are achieved.

Description

technical field [0001] The invention relates to a novel dimmable blind with blades that can be rolled up and turned over, which is suitable for residential buildings, commercial buildings and other public buildings.
