Description

[Detailed description of the invention] (Field of application of the invention) This invention relates to a movable louver.

(Prior art) In general, movable louvers consist of a plurality of louvers that are fitted and supported on both ends or lips of a sash board, arranged vertically in parallel within a sash frame, and a clip that is pivotably attached to a vertical frame of the sash frame. The ends of each clip of each of the upper and lower louvers are connected via a connecting rod, and by moving this connecting rod up and down, the clip is rotated and each louver is opened and closed. . When the louvers are closed, each louver is tilted, and its upper and lower end surfaces overlap with other louvers in a staggered manner, thereby maintaining watertightness between adjacent louvers. In addition, tight material was attached to the vertical frame of the sash frame in a continuous manner above and below, and the outer surface of each louver's clip was brought into contact with this tight material to maintain watertightness between the louver and the vertical frame. .

However, the watertight structure of the above structure, especially the watertightness between each louver and the vertical frame, was insufficient. This is because the width of the clip that supports the end of each louver is only wide enough to fit one blade, and each louver is configured to tilt obliquely when closed and overlap with other louvers in a stepped manner. from,
The outer surface of the clip has a zigzag shape as a whole, and
This is because the overlapping portions tend to become discontinuous, resulting in uneven contact between the vertical frame and the tight material.

(Technical Problem of the Invention) An object of the present invention is to solve the above-mentioned drawbacks, and particularly to propose a movable looper that can significantly improve watertightness.

(Technical means for solving the problem) That is, in the movable louver according to the present invention, clips provided at both ends of a plurality of loopers are rotatably attached to a vertical frame constituting a sash frame, and A movable looper that opens and closes the louver by rotating the clip.

When the looper is closed, each clip is brought into contact with another clip through a tight material, and the outer surface of the clip of each louver is continuous vertically, and the continuous outer surface of the clip is placed inside the vertical frame. It is characterized in that it comes into contact with tight materials that are continuously formed vertically.

(Operations and Effects of the Invention) As described above, in the movable louver of the present invention, the clips of each louver are brought into contact with each other through the tight material, and the outer surfaces of the vertically continuous clips are brought into contact with the tight material of the vertical frame. Since the louver clip and the vertical frame tight material are both vertically continuous, the upper and lower clips and the vertically continuous clip and the vertical frame are both in good and secure contact, and as a result, the louver and the vertical frame are It can improve the watertightness between the gaps.

(Example) Hereinafter, an example of implementation of the present invention will be described with reference to the drawings.
