Shutter and control method

Abstract

The invention relates to a shutter, having revolving and retracting functions, including a window frame for holding the leaves, a revolving device, a retracting device, a driving device, and a transmission device. The revolving device is used for revolving each leaf at each angle at the same time; the retracting device is used for lifting all the independent leaves horizontally and collecting to the top of the window frame, putting down all the leaves, to collocate in the window frame evenly; the driving device is used for supplying power to the retracting device and the revolving device; the transmission device is used for transmitting the power to the retracting device and the revolving device. The invention also claims a control method of a shutter, including: starting the retracting motor forward and reverse, for collecting and unfolding the leaves; starting the revolving motor forward and reverse, for locating and resetting the leaves. The invention can make the leaves operated in normal order and return to the normal state correctly under failure, which can improve shielding, collecting light, ventilating and expanding view field.

Description

technical field [0001] The invention relates to building doors and windows, in particular to a shutter with rotatable and retractable blades and a control method. Background technique [0002] The existing shutters of building doors and windows can be divided into fixed type, sash opening type, sash translation type and blade rotation type. The blades cannot move vertically or parallelly, which will affect the permeability and openness of the line of sight, as well as lighting and ventilation; while the blades For movable shutters, the blades are mostly connected together by wires or steel wires, and due to the structural limitations of the product itself, it can swing with the wind and lacks stability. It is not suitable for installation and use outdoors. It is only suitable for indoors or in the middle of glass interlayers, and cannot block sunlight and heat. Outdoors, ventilation, vision and lighting are also affected. Contents of the invention [0003] In order to ove...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiency that the blades of the shutters of the existing building doors and windows cannot have the functions of rotation and retraction at the same time, the present invention provides a shutter and a control method for the shutters. Each blade is independent of each other, has the functions of rotation and retraction, and can normally Improved shading, daylighting, ventilation and visibility performance due to sequential execution and proper recovery to normal conditions in the event of a failure
