Description

{Curtains with privacy and complementary functions and natural ventilation and heat insulation functions {natural air ventilative and heat insulative curtain apparatus ensuring privacy and security}

The present invention relates to a curtain which hangs on a front door or a window. More particularly, the present invention relates to a curtain which is provided on one side of a door frame such as a front door or a window by a screw or the like, A plurality of curtains coupled to the support shaft are connected to one side and the upper side between the other side support rods by the both end portions of the supporting shaft supporting the two support rods so as to allow ventilation and at the same time a plurality of curtains are rotated at a predetermined angle to close the light or heat In the state where the curtains are unfolded and kept at a constant interval, the indoor and outdoor ventilation is smooth and the pleasant environment of the room can be produced. In addition, the auxiliary door is installed on the front door or window in winter, The effect can be increased and a plurality of curtains are placed in a superimposed state And expanded so as to be in a ventilated conditions only relate to curtains with privacy and complement the natural ventilation and thermal insulation capabilities to get the privacy protection to avoid completely the external gaze.

Conventionally, there is a utility model registration No. 20-0315116 entitled "Ventilation door with crime prevention blinds "

The above-mentioned prior art has a main door installed on a door frame; A window formed to pass through the front / rear surface of the main door so that external air can flow smoothly; A sub door hinged to a rear surface of the main door so as to be opened and closed corresponding to the window; A window frame installed inside the main door and having a size relatively larger than the window to include the window; An insect screen installed on the other surface of the window frame; And a blind to be selectively hinged on the window frame so as to be angularly adjustable so as to be positioned in front of the insect control net.

That is, the above-described prior art is an invention that satisfies privacy and security aspects.

However, these days, it is usually common to open the front door during the day and clean the room while ventilating the room.

In addition, since the above-mentioned prior art mounts screen guards on a window formed with a small area, the distance from the purpose of ventilation of air is distant, and it seems to be mainly for obtaining a crime prevention effect and insect proof effect.

SUMMARY OF THE INVENTION An object of the present invention is to solve such conventional problems,

In the state that the curtains are unfolded and kept at a constant interval, the indoor and outdoor ventilation is smooth, and the comfortable environment of the room can be produced. In addition, the auxiliary wall is provided at the entrance door and window in winter, And the curtains are placed in a state in which the curtains are overlapped with each other or only the ventilation is performed even when the curtains are laid open. Therefore, the object of the present invention is to provide a privacy protection effect that can completely avoid the external gaze.

In order to achieve the above object,

The upper and lower supports are fixed by both ends of a support shaft which has one side and the other side support rods fixed to both sides of the door frame such as the front door or a window by a screw or the like and has a plurality of curtains inserted into curtains A plurality of curtains connected to the support shaft are unfolded to allow airflow, and at the same time, a plurality of curtains can be closed by turning at a predetermined angle to block light or heat, thereby achieving the object of the present invention.

According to the present invention as described above, when the curtains are unfolded and maintained at a constant interval, the indoor and outdoor ventilation can be smoothly performed, so that a pleasant environment of the room can be produced.

According to the present invention as described above, since auxiliary walls are provided on the front door or window in winter to serve as a double wall, it has an effect of enhancing the warming and light compensating effect.

In the present invention as described above, since only a plurality of curtains are placed in a state in which the curtains are overlapped with each other or only the ventilation is performed in a state in which the curtains are laid open, it is possible to obtain a privacy protection effect that can completely avoid an external gaze.

Hereinafter, the operation of the present invention will be described.

Fig. 1 is a perspective view for explaining a construction for opening and closing the curtain of the present invention, Fig. 2 is a front sectional view for explaining a construction for opening and closing the curtain of the present invention, The curtains 101 coupled to the supporting shaft 116 connecting the supporting member 111 and the upper side of the other supporting member 114 are spaced apart from each other with a predetermined distance therebetween.

Of course, the curtains 101 freely couple the coupling holes 102 to the support shaft 116, but these are shown in the drawings for the sake of explanation, and the movement and rotation distances of the curtains 101 are substantially A groove, a jaw, or a washer, etc., may be combined to limit it.

As shown in FIG. 3, when the curtains 101 coupled to the supporting shaft 116 are positioned at a predetermined interval, ventilation can be smoothly performed inside and outside the room, And can be usefully used in summer.

In addition, although the curtains 101 can be ventilated as described above, since the outer lines of sight are all processed in a rectangular shape, the privacy effect can be obtained.

When the knob 122 protruding from one side of the rotating body 121 of the one support stand 111 is rotated by pushing with the finger and rotated to obtain the effect of blocking the winter wind or insulating effect, 121 are rotated.

The eccentric shaft 124 connected to the rotating body 121 by the rotation of the rotating body 121 is also supported by the supporting body 125 coupled to the coupling chamber 115 of the other supporting base 114, .

As described above, the rotation of the eccentric shaft 124 results in pushing the plurality of connection rings 103 coupled to the eccentric shaft 124 in the direction of the support shaft 116, The coupling holes 102 of the curtains 101 are rotated while starting from the supporting shaft 116 to be closely contacted with each other as shown in FIG.
That is, the wings of the curtain 101 can be moved in the forward and backward directions by the gap between the eccentric shaft 124 and the rotating body 121. The eccentric shaft 124 The difference in the upper and lower intervals generated during the rotation allows the lower side of the curtain 101 of soft material to which the connecting ring 103 is attached to be slightly lifted upward or downward to allow the upper and lower movement of the connecting loop 103 So that the curtain 101 can be smoothly moved forward and backward.

Accordingly, since the blades of the curtains 101 are in close contact with each other, they are hermetically sealed, thereby preventing wind, light or heat from passing through the door, window, or the like.

On the other hand, if the knob 122 is rotated by a predetermined angle by hand and the rotating body 121 and the eccentric shaft 124 are rotated, they must be held in place. This is because the tangential ball 131 which is resiliently urged by the elastic member 132 in the cap 113 of the one support rod 111 is inserted into the plurality of stop grooves 123 formed on the outer circumferential surface of the rotating body 121, Therefore, the rotating body 121 is not rotated by the gravity, and the rotating body 121 is held in place.
