Abstract

Disclosed is an external air blocking-type displacement prevention screen shutter. According to the present invention, the external air blocking-type displacement prevention screen shutter comprises: a winding roller unit which is fixated and installed on a ceiling of a building and is installed to be able to be rotated by receiving power of a driving motor; a screen blocking film which has one side, joined to the winding roller unit, and the other side, extended downward, and is raised up or placed down by rotation of the winding roller unit; a lower end weight bar which is joined to a lower end portion of the screen blocking film in a widthwise direction and provides a weight; one or more middleweight bars which are placed apart at intervals and joined in a widthwise direction of the screen blocking film; a pair of guide frames which are close to a lower portion of the winding roller unit, are installed to be perpendicular to a bottom surface, and have guide grooves having snagging protrusions therein formed in a lengthwise direction; and a bearing unit which is joined to end portions of both lateral sides of the lower end weight bar and the middleweight bar, is guided to the guide grooves of the guide frames, and prevents the lower end weight bar and the middle weight bar from escaping from the guide grooves by the snagging protrusions of the guide grooves. According to the present invention, the screen blocking film is rapidly raised up and placed down and thus is smoothly inserted in an indoor space and smoothly extended to an outdoor space. A plurality of weight bars are installed on the screen blocking film, and the bearings are joined to both end portions of the weight bars. Consequently, the screen blocking film is prevented from being dislodged from the guide grooves. Therefore, the external air blocking-type displacement prevention screen shutter prevents rainwater from penetrating an indoor space, effectively blocks external air, and maintains the optimal temperature of an indoor space.

Description

{Breakaway Preventing Shutter of Outside Weather Blocked Type}

More particularly, the present invention relates to an outside air blocking type departure prevention screen shutter, and more particularly, to an outside air blocking type departure prevention screen shutter which is installed in various places such as a garage and a car repair shop adjacent to the outside, Shielding screen shutters that effectively block the falling of the screen shielding film due to the strong outside wind pressure and minimize the heat loss in the room.

Generally, the screen shutter is installed in a place adjacent to the outside, and is installed and used so as to smoothly enter and exit the room and outdoors, and to prevent infiltration of outside air and maintain the proper temperature in the room.

In addition, in order to block the outside air, the screen shutter is guided by the guide bar to both sides of the weight bar coupled to the lower end of the screen cloth, and the lowered screen cloth is generated due to intrusion of rainwater, When the pressure applied to the screen is applied to the screen, the weight bar at the bottom of the screen cloth, which is drawn into the guide bar, is separated from the guide bar, and the outside air penetrates into the room.

However, since the screen shutter is rapidly lowered or raised, it is possible to smoothly pull in and out of the room and outdoors, effectively shielding the outside air, and at the same time, the weight bar on the lower side of the screen cloth There is a need for a screen shutter capable of blocking the outside air and minimizing the heat loss in the room, and research has been conducted actively.

The conventional screen shutter is divided into a screen shutter type in which the screen cloth can be bent and bent, and a screen shutter type door type in which the wind is cut off. The screen shutter in which the screen cloth is provided with a bent or curved screen is folded into a screen cloth folder type so as to have a structure It is possible to freely refract and bend the screen in a place where the user desires to install the display device such as "A" or "S". However, there is a difficulty that the screen transition is separated from the screen guider due to strong draft,

As a conventional technique of a screen shutter, Korean Patent Laid-Open Publication No. 10-2012-0046958 (Nov. 3, 2010) discloses a screen shutter type door that uses an inlet of a screen shutter type door to cut off an outside wind and forms a film in a space formed between the wind- There is proposed a screen door which blocks air from communicating with the internal passage of the frame.

However, such a screen door is merely to cut off the outside air and cut off the air drawn through the windup frame to minimize heat loss. When a strong outside wind pressure is applied to the lowered screen cloth, The portion where the heat loss is increased is not taken into consideration, so that the portion that maintains the proper temperature in the room is unexpected.

The frequent departure of the screen cloth due to the drafts causes the energy efficiency of the cooling and heating to be maintained to maintain the indoor temperature appropriately, resulting in poor economical efficiency, and the durability of the screen shutter is lowered. There is a problem that can be inefficient.
