Problems solved by technology

However, according to this structure, the force is concentrated on the side connected to the rope, so there is a problem that when used for a long time, the shutter device becomes unbalanced or the connection between the roller and the rope is easily broken
[0005] In addition, when the rope hangs down for too long, people, especially careless children, can easily trip over it, so safety accidents are likely to occur
Also, the entire roller needs to be rotated and balanced with a rope attached to one side of the roller, so the rotating structure is unnecessarily complicated and presents many other problems

Abstract

A blind apparatus is provided. The blind apparatus includes: a plurality of rolls respectively coupled to rotary shafts that are parallel with each other; a plurality of screens respectively wound onor unwound from the rolls; and a plurality of weights respectively connected to the lower ends of the screens and applying torque in a first direction in which the screens are unwound to the rolls using gravity, in which the weights are combined with each other by magnetic force.

Description

technical field [0001] The present application relates to a shutter device, and more particularly, to a shutter device that can be operated conveniently. Background technique [0002] Louvered installations are installed to block direct sunlight through the windows or gaze from the outside. By appropriately adjusting the amount of light using the shutter device, it is possible to make the interior atmosphere more comfortable with a soft glow effect. The shutter device is installed above the window and has a structure capable of opening / closing. [0003] Blind installations may include roll-up and roll-out curtains. The amount of light can be adjusted by opening part or all of the window and adjusting the size of the curtain. In such roller blind arrangements, the size of the shade can be adjusted using a cord which enables the roller to rotate. [0004] That is, the existing blind device is formed such that a user can easily rotate the roller on the window by pulling dow...
