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 in which both ends of a wing plate are fitted and supported by clips, which are arranged vertically in parallel within a sash frame, and the clips are rotatably pivoted around the 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 each louver is closed, each louver is tilted, and its upper and lower end sides overlap with other louvers in a staggered manner, thereby maintaining watertightness between adjacent louvers. In addition, tight material is attached to the vertical frame of the sash frame in a continuous manner vertically, and the outer surface of each louver's clip is brought into contact with this tight material to maintain watertightness between the louver and the vertical frame. Ta.

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 the slats, and each louver is configured to tilt obliquely and overlap with other louvers in a stepped manner when closed. Therefore, the outer surface of the clip has a zigzag shape as a whole, and the overlapping portion tends to be discontinuous, which causes uneven contact with the tight material of the vertical frame.

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

(Technical means for solving the problem) That is, in the movable louver according to the present invention, the clips provided at both ends of each of the plurality of louvers are rotatably attached to the vertical frame constituting the sash frame, and In the movable louver, which opens and closes the louver by rotating the clip, when the louver is closed, the vertically opposing end surfaces of each clip are brought into contact with each other via a tight material, and the outer surface of the clip of each louver is The clip is characterized in that it is continuous in a band shape vertically through a tight material, and the continuous outer surface of the clip is brought into contact with a tight material that is continuously formed vertically inside the vertical frame.

(Operations and Effects of the Invention) In the above structure, since the end surfaces of the vertically opposing clips are in contact with each other via the tight material when the louver is closed, watertightness between the upper and lower clips can be maintained well. In addition, since the outer surface of each louver's clip is continuous in a band shape vertically through the above-mentioned tight material, the tight material inside the vertical frame is narrow and continuously formed vertically in a straight line. Also, the continuous outer surface of the clip can be brought into reliable contact with the tight material.

Therefore, according to the present invention, watertightness between the clips and between the vertical frame and the louver can be improved.

(Example) An example of implementing the present invention will be described below with reference to the drawings.

In the figure, symbol A is a sash frame, B is a movable louver, and the movable louver B is installed in the sash frame A so that it can be opened and closed.

The sash frame A is formed by framing an upper frame 1, a lower frame 2, and left and right vertical frames 3 into a rectangular shape, and is fastened and fixed to a structural member 4 constituting a window opening of a building.

On the opposing surfaces of the left and right vertical frames 3, two narrow tight members 5 and 6 parallel to the outdoor and indoor sides are installed vertically and continuously in a straight line, and there is a recess between these tight members 5 and 6. A groove 7 is formed. In this case, the concave groove 7 extends in the longitudinal direction of the ridge 8 provided with the engaging protrusions 11 and 12.
Parallel grooves 13 and 14 are formed across the edges, and tight materials 5 and 6 are fitted into these grooves 13 and 14 to form engaging protrusions 11 and 12 of the ridge 8 on the vertical frame 3 of the ridge 8. What is necessary is just to adopt the structure which engages with the receiving parts 15 and 16, and fixes the ridge 8 to the vertical frame 3. The tight members 5 and 6 may be made of an elastic material such as mohair or synthetic resin.

Next, the movable louver B has a plurality of louvers 9,
Clip both ends of 9, 9... 10, 10, 10
These clips 10,
10, 10... are respectively pivotally attached to the vertical frame 3 of the sash frame A, and their ends are connected to a common connecting rod 17, and the louver 9 is made of a glass plate or a synthetic resin plate, The clip 10 is made of metal or synthetic resin such as polyamide or polyacetal.

The clip 10 is formed wide, and has a louver fitting groove 20 formed on its inner surface, and a first abutting surface 23 and a second abutting surface 24 with a recess 22 sandwiched between the outer surface. ing. The first contact surface 23 and the second contact surface 24 are flush with each other, and the first contact surface 23 and the second contact surface 24 are flush with each other.
3 is formed on the opposite side of the louver fitting groove 20. Next, the lower side portion 26 of the clip 10 is formed to be continuous from the overlap portion 25 and parallel to the upper side portion 27. A protrusion 28 is formed on the lower side portion 26. Furthermore, a protruding piece 21 is provided on the opposite side of the clip 10 from the louver fitting groove 20, and a shaft hole 29 is formed approximately in the center of the clip 10.

The louver 9 is fitted into the louver fitting groove 20 of the clip 10. In this case, an airtight material 30 made by double extrusion molding of hard and soft vinyl chloride is fitted onto the upper end surface of the louver 9, and the clip 1
The edge receiving member 3 of the louver 9 is placed in the fitting groove 20 of 0.
1 is attached, and the end of the louver is in contact with the receiving member 31. Furthermore, a tight material 32 provided along the lower side 26 is attached to the protrusion 28 of the lower side 26 of the clip 10. The tight material 32 and the edge receiving member 31 may be formed from a resin foam material such as vinyl chloride, or an elastic material such as rubber.

Next, the clips 10 of each louver 9 are attached to the upper and lower clips 10, 10 by inserting the shaft 18 attached to the sash vertical frame 3 into the shaft hole 29.
However, the lower end surface of the lower side of the upper clip 10 and the upper end surface of the upper side 27 of the lower clip 10 are in contact with the vertical frame 3 via the tile material 32, and are pivotally supported in a vertically continuous position. . And like this, clips 10, 10, 1 of louvers 9, 9, 9...
0... continues vertically in a band shape, the first contact surface 23 on the outer surface of each clip 10 contacts the outdoor tight member 5 of the vertical frame 3, and the second contact surface 24 contacts the outdoor tight material 5 of the vertical frame 3. The concave groove 7 of the vertical frame 3 is in contact with the inner tight material 6, and is provided so that an integral space S is formed opposite to the concave portion 22 of each clip 10. Further, gap closing members 3 are provided at the upper part of the uppermost clip 10 and the lower part of the lowermost clip 10, respectively.
3 and 34 are installed. A space communicating with the space S is formed inside the lower gap closing member 34, and this space further communicates with the outside from the lower frame 2 as shown by the arrow. Therefore, the external pressure and the internal pressure of the space S are formed to be equal pressure.

Furthermore, the projecting pieces 21 of the louvers 9, 9, 9...
21, 21... are connected to a connecting rod 17, and the connecting rod 17 is further connected to a known actuating device (not shown).

Airtight material 3 is placed on the upper frame 1 and lower frame 2 of the sash frame A.
5 and 35 are attached so as to be able to come into contact with the uppermost and lowermost louver 9 surfaces, respectively.

When using movable louver B with the above configuration,
The actuating device may be actuated manually or automatically. As a result, the connecting rod 17 moves up and down, and the clips 10, 10, 10 rotate around the shaft 18, so that the louvers 9, 9, 9... rotate at the same time.
Movable louver B opens and closes. When the movable louver B is closed, the lower end surface of the lower side 26 of the upper clip 10 and the upper end surface of the upper side 27 of the lower clip 10 are in contact with each other via the tile material 32, so that the upper and lower clips 10, 10 The watertightness of the clip 10 is maintained well, and the clip 10 is continuous in a band shape from top to bottom.
A first contact surface 23 on the outer side of the vertical frame 3 contacts the outdoor tight material 5 of the vertical frame 3, and a second contact surface 24 contacts the indoor tight material 6. This reliably prevents rainwater from leaking between the louvers 9, 9, 9, . . . and the vertical frame 3. In this way, each clip 10 is brought into contact with another clip 10 via the tight material 32, so that the outer surfaces 23, 24 of the clips of each louver 9, 9, 9, etc. are vertically continuous, and Since the end faces 23 and 24 are brought into contact with the tight members 5 and 6 of the vertical frame 3, rainwater is reliably prevented from entering the room, and the watertight performance is much improved compared to the conventional one.

Note that when the louver 9 is closed, the upper louver 9
The lower end side surface overlaps the airtight material 30 on the upper end side surface of the lower louver 9. Therefore, rain is prevented from blowing up from the overlapping portion of the upper and lower louvers 9. In addition, since the space S formed between the tight members 5 and 6 communicates with the outside air, the space S inside the sash vertical frame 3 and the outside pressure are equal to each other, so that the outdoor wind pressure, etc. This is greater than the internal pressure indoors, creating a pressure difference between indoors and outdoors, which prevents rainwater from drawing indoors.Furthermore, even if rainwater enters between the outer tight material 5 and the louvers 9, this Rainwater is drained outdoors from the space S.
