The present invention relates to a louver door, and more particularly to a louver door provided with a deflection prevention device.

Originally used in Western countries, window louvers were used as narrow and small dimensions on the outside of windows to protect the glass and cover the sun. The louver-type doors, which have recently been applied in Korea and are generally used, are significantly larger in size and are installed for the purpose of ventilating the balcony of the apartment, the machine room of the rooftop of the apartment, and the outdoor unit of the air conditioner installed in the commercial building of the residential complex Installed to mask out of the building. In addition, the louver-type doors are built in the form of swing doors so that they can be used for emergency evacuation.

1A to 1C are front views illustrating the operation of a louvered door according to the prior art. The louver-shaped door 10 according to the prior art is configured to form a rectangular frame by connecting the frame 11 of the rectangular shape in the upper and lower sides and left and right, and these frames 11 are fixedly installed so as not to move through the hole of the building wall. . The louvered door 12 is fixed to the inner space of the frame 11 in the form of a casement.

The conventional louvered door 12 maintains its position inside the frame 11 by relying on two hinges provided at one end. However, this louvered door 12 is left unused for a long time unless an emergency occurs. In this case, over time, the self-loading of the louver-type door 12 causes loosening of the assembly part such as the fitting structure of the louver opposite to the hinge, and sags in the direction of gravity, and eventually the frame 11 in the lower part. The frame 11 is pressed while in contact with it. Thus, when an emergency arises and the evacuation is necessary, the door does not open easily, and it is difficult to evacuate.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a louver-type door having a deflection preventing device for easily opening and closing by preventing sagging of the louver-type door.

Hereinafter, a louvered door having a deflection prevention device according to a first embodiment of the present invention will be described in detail with reference to FIGS. 2 to 4.

FIG. 2 is a front view and a partially enlarged view of a louver type door equipped with a deflection preventing device according to a first embodiment of the present invention, FIG. 3 is a perspective view of the tree shown in FIG. 2, and FIG. 4 is IV of FIG. 3. It is sectional drawing along line -IV.

As shown, the louver door 100 is provided with a deflection prevention device according to the first embodiment of the present invention is a frame 110, a louver door 120 and a stump 130 installed in a hole in the wall ).

Here, the louver-type door 120 is hinged using a hinge (not shown) to open and close the inside of the frame 110, and is installed in multiple stages in the inner central portion of the door frame 121 provided in all directions to be rotated. The louver 122 is provided to open and close, and the handle 123 is operated to open or close the louver 122 or to open and close the louver-type door 120.

The wood block 130 is installed between the lower end of the louver-type door 120 and the frame 110 so as to support the bottom to prevent sagging of the louver-type door 120. In the present exemplary embodiment, the wood block 130 is installed at the lower end of the louver-type door 120, but in some cases, it may be installed at the upper surface of the lower end of the frame 110.

The stump wood 130 according to the first embodiment of the present invention includes a coupling part 131, a pillar part 132, and a curved part 133.

The coupling part 131 is a member of a flat plate shape to be inserted into the lower inner side of the louver-shaped door 120 to be screwed, the pillar portion 132 protrudes to the lower portion of the coupling part 131 to the Is provided to support between the lower end of the louver-shaped door 120 and the frame 110, the curved portion 133 is curved in the shape of an arc in the longitudinal direction and the width direction on the lower surface of the pillar portion 132 Minimizing the friction surface with the bottom of the frame 110.

Here, the pillar portion 132 is shown as a single body in the form of a 'T' perpendicular to the coupling portion 131, but is not connected to be inclined vertically or connected to the edge of the coupling portion, etc. Modifications are possible. In addition, in the drawings, the pillar portion 132 is illustrated as having a rectangular shape having the same width as that of the upper and lower portions. However, the width of the upper portion is narrower and narrower toward the lower portion.

5A to 6C will now be described in detail the chorus according to the second embodiment of the present invention.

5a to 6c is a perspective view, a cross-sectional view and a front view according to the position of the height adjustment seat of the stump according to the second embodiment of the present invention.
