Is configured by rotatably incorporating a plurality of horizontally arranged blades 33 in the window frame 32. Each blade 33
Is a pair of front and rear louver glasses (double glass) 34a, 34, which are panel bodies arranged in parallel with each other with a gap.

Each mounting frame 35 is formed with an arm portion 35a that bends and extends toward the indoor side, and the blade plate 33 is rotatably attached to the vertical frame 32a at the base of the arm portion 35a. In addition, the tip of the arm portion 35a has a vertical frame 32a.
It is rotatably attached to an operating rod 36 which is attached to the upper and lower portions of the blades 33. When the operating rod 36 is moved up and down, the blade plate 33 moves horizontally to an open position and the adjacent blade plate 33. It is opened and closed between a closed position where the upper and lower ends overlap.

The blades 33 are assembled so that the louver glass 34a on the outdoor side is on the lower side and the louver glass 34b on the indoor side is slightly shifted to the upper side, and in this state,

[0004]

By the way, the blade plate 33 of the movable louver 31 generally has a width of 90 mm, and since the blade plates 33 are mounted by overlapping them vertically, the interval (pitch) is 70 mm to 80 mm. I am trying to install it. Actually, since the opening height of the building to which the movable louver 31 is attached is in accordance with the building module, the attachment parts of the blade plate 33 such as the operating rod 36 are 70 mm.
About 4 types are prepared with a pitch that fits within ~ 80 mm so that they can be used for several general types of opening heights. However, not all building heights, including the problem of construction accuracy, comply with the building module, and there are many cases where on-site fine adjustment is necessary.

Under these circumstances, in the above-described conventional louver blade mounting structure, a minute gap () is formed between the front surface of the outdoor louver glass 34a rotated to the open position and the lower end of the upper frame 32b. Since there is only "C" dimension shown),
There was a problem that fine adjustment could only be done within this range. For this reason, the blade plate 3 is not provided for the openings that do not match the above-mentioned four types of pitches, that is, for the openings that are far away from the building module.
There was a problem that the movable louver 31 itself could not be adopted due to the pitch problem of 3. Also, in the closed position,
Since a narrow space is formed between the upper end of the louver glass 34a on the outdoor side and the lower end of the upper frame 32b, the upper frame 32 is formed in this portion.
The structure was such that rainwater flowing down from b was liable to collect in the water (vortex flow), and the watertightness was easily impaired.

An object of the present invention is to provide a mounting structure for a louver vane plate, which can structurally easily maintain watertightness and can increase the adjustment range of mounting.

[0007]

In order to achieve the above object, the present invention is a louver for rotatably mounting a blade plate, which is formed by combining two panel bodies in parallel with each other with a gap therebetween, to a window frame. In the mounting structure of the blade plate for the blade,
When the blade is rotated to the open position where it is in a substantially horizontal posture, the outdoor panel body is arranged so that the upper end of the outdoor panel body is located on the outdoor side with respect to the outdoor side found surface of the window frame. It is characterized in that it is combined with the panel body on the indoor side while being shifted downward.

[0008]

When the vane plate is rotated to the open position where the vane plate is in a substantially horizontal position, the upper end of the panel body on the outdoor side is located on the outdoor side with respect to the outdoor-side found surface of the window frame. Since the panel body on the outdoor side is combined with the panel body on the indoor side by shifting it downward, the panel body on the outdoor side is It completely projects to the outside from the found surface of the window frame, and at the topmost blade, the panel body on the indoor side is located directly below the upper frame of the window frame. That is, in the uppermost blade, there is a minute gap between the outdoor surface of the outdoor panel body and the lower edge of the upper frame of the window frame when viewed from the horizontal direction. Then
Between the lower end of the upper frame and the panel body on the indoor side, there is a sufficient gap including the step difference between both panels. Therefore, within the range of this gap, the entire height of the blade plate can be finely adjusted without changing the arrangement pitch of the blade plate.
In addition, a sufficient space is inevitably created between the upper panel of the uppermost blade in the closed position on the outdoor side and the lower edge of the upper frame. Does not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A case in which the mounting structure of a louver blade according to an embodiment of the present invention is applied to a general movable louver will be described below with reference to the accompanying drawings. As shown in the perspective view of FIG. 1 and the vertical sectional view of FIG. 2, the movable louver 1 includes an upper frame 2b and a lower frame 2 on both left and right vertical frames 2a, 2a.
A plurality of horizontally arranged blades 3 are rotatably incorporated into a window frame 2 framed by c. A screen door 4 is provided on the indoor side of the movable louver 1 so as to be fitted into the window frame 2.

Each vane plate 3 is a pair of front and rear louver glasses (double glasses) 5a and 5b, which are panel bodies arranged in parallel with each other with a gap, and a pair of louver glasses 5a and 5a.
It is composed of a pair of left and right mounting frames 6 that integrally hold 5b at both ends thereof. Each mounting frame 6 is composed of a holder 7 for sandwiching and fixing a pair of louver glasses 5a, 5b integrally, and a clip 8 for holding the holder 7. The clip 8 is formed with an arm portion 8a that bends and extends upward toward the inside of the room, and the blade plate 3 has the arm portion 8a.
It is rotatably attached to both vertical frames 2a via a rotation shaft 9 at the base of the above. The tip of the arm portion 8a is attached to the support shaft 1
It is rotatably attached to an operating rod 11 which is vertically movably incorporated in the vertical frame 2a through 0, and the operating rod 11 is moved up and down to rotate the arm portion 8a around the rotating shaft 9. As a result, all of the blade plates 3 are simultaneously opened and closed between the horizontally moved open position and the closed position where the upper and lower ends of the adjacent blade plates 3 overlap. Although not shown, the operating rod 11 is connected to an operation handle provided on the inside of the room via an interlocking link, and the blade 3 can be opened and closed by rotating the operation handle forward and backward. .

Reference numeral 12 in FIG. 2 indicates the lower surface of the upper frame 2b and the louver glass 5b on the indoor side of the uppermost blade 3.
Is an upper seal member interposed between the front surface of the upper end of the
Reference numerals 13 and 13 denote vertical sealing members interposed between the front inner surface of the vertical frame 2a and the end surfaces of the outdoor louver glass 5a and the indoor louver glass 5b. Although not shown, a pair of lower seal members are also interposed between the lowest outdoor side and indoor side louver glasses 5a and 5b. That is, these seals 12, 13
However, it is continuous over the entire circumference of the window frame 2, and the watertightness between the window frame 2 and the blades 3 is maintained.

Each blade 3 is a louver glass 5 on the outdoor side.
The upper end of a and the lower end of the louver glass 5b on the indoor side are combined with a large shift so that the overlap width becomes small. Each blade 3 configured in this way
Are attached to the vertical frame 2a with a certain interval (pitch) between the upper and lower blades 3 and 3 which are adjacent to each other. However, the louver glasses 5b, 5b on the indoor side are arranged such that the upper end portion and the lower end portion of the louver glasses 5b overlap each other. Further, the vane plate 3 in the open position is in a state in which the louver glass 5a on the outdoor side is completely projected to the outdoor side from the found surface of the window frame 2. That is, the step portion 1 of the vane plate 3 constituted by the upper end of the louver glass 5a on the outdoor side
The reference numeral 4 is adapted to be rotated right below the upper frame 2b between a closed position which is sufficiently separated from the upper frame 2b and an open position which is diagonally forward of the upper frame 2b.

In this open position, the louver glass 5a on the outdoor side, which is rotated to be horizontal when viewed from the outdoor side in the horizontal direction, is horizontal.
There is almost no gap between the front surface and the lower end of the upper frame 2b, and there is no appearance discomfort. On the other hand, immediately below the lower end of the upper frame 2b, the step portion 14 of the vane plate 3 is located, and between the lower end of the upper frame 2b and the vane plate 3, both louver glasses 5a and 5b are vertically arranged. A gap "A" is formed in the step by adding a gap formed between the lower end of the upper frame 2b and the front surface of the louver glass 5a on the outdoor side.

Therefore, within the dimension of the gap "A", the pitch of the vanes 3 and 3 is not changed,
The height of the entire blade 3 can be finely adjusted, and the height of the movable louver 1 that is not based on the building module can be adjusted. In addition, since the size of the gap “B” between the lower end of the upper frame 2b and the stepped portion 14 of the blade plate 3 in the closed position is considerably large, swirling is unlikely to occur in the rainwater flowing down in this portion, and the rainwater does not easily flow. The flow becomes smooth and the watertightness of this part can be improved. Moreover, since the louver glass 5b on the indoor side is hard to see not only in the closed position but also in the open position, it looks like a single glass vane plate 3 despite the double glazing, and follows the clean design in appearance. You can

In this embodiment, an example in which a glass plate is used as the panel body constituting the vane plate has been described, but it goes without saying that the invention can be applied to those using other synthetic resins or metal plates. Absent.

[0016]

As described above, according to the mounting structure of the louver blade of the present invention, the uppermost blade and the window frame are not only in the closed position but also in the open position in a state where there is no discomfort in appearance. Since a vertical space can be formed between the frame and the lower end of the frame, it is possible to easily maintain the watertightness structurally, and to increase the adjustment width of the mounting, which is Thus, it is possible to configure a blade plate having a degree of freedom.
