Description

Changeable shutter

Technical Field

The present invention relates to a replacement blind, and more particularly, to a replacement blind including: in order to improve the heat insulation performance of the window, the louver blades arranged outside the window chamber are replaced easily.

Background

Generally, a plurality of destination windows for an entrance and exit passage, ventilation, lighting, and the like are provided in a wall of a building, and are formed of a glass plate and a frame surrounding the glass plate, and are fixed as in the case of a wall, or opened and closed by sliding or rotating by a hinge.

In the past, curtains have been mainly used in order to adjust the amount of light flowing into a room from the outside or to prevent external peeping in order to protect privacy, and in the case of curtains that are frequently exposed, there has been inconvenience in management due to dirt and dust generation, and recently, simple roller or roll blind type blinds have been mainly used.

Such a blind device is additionally constructed on the outer wall and the front end of various windows, and a bracket for supporting the blind device is required to be installed on the ceiling or the upper frame. In this case, when the installation surface is made of cement or a steel bar structure, a special tool such as a drill is required to install the bracket, and a complicated installation process is required, and the installation surface of the bracket is damaged.

Further, as the individual manufacturing is performed according to the specification of the window to be installed, it requires an expensive construction cost and deteriorates the beauty of the building. That is, in a state where construction related to a window of a building is completed, a blind apparatus generally needs to be installed by additional work, and thus, additional workers, time, and expenses are consumed, and the width and width of the blind apparatus have to protrude from the outer surface of the frame of the window, and thus, in the process of constructing many windows, the appearance is not ideal particularly for modern buildings having a structure in the form of a curtain wall as each blind apparatus is protruded.

In addition, in general, a louver is not installed on the indoor side to improve the Heat insulation performance of a window but to shield light, and in europe, particularly, in northern european countries including germany, korea, japan, and the like, the enhancement of the Heat insulation performance of a window is strongly promoted, and in the united states, the united kingdom, australia, and mediterranean coastal countries, Heat transfer coefficients, air tightness, and Solar Heat Gain coefficients (hereinafter SHGC) are proposed as suggested arrangements, not obligations.

On the other hand, although the window is a skin element that contributes most to energy consumption of a building, once installed, the window cannot be replaced within 15 to 20 years, and therefore, the window selected is particularly important.

In addition, in the case of a rental building, even if there are windows to be applied uniformly regardless of the use and interior decoration, they can be used as they are.
