DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a louver window provided in an opening of a building requiring ventilation as required, such as a bathroom.

[0002]

2. Description of the Related Art A louver window has a structure in which each panel has a slightly inclined posture so that the vertically adjacent panel surfaces are brought into contact with each other when the window is closed.
No. 083, No. 57-21188, No. 4-41
As disclosed in Japanese Patent No. 087, there is a structure in which each panel is vertically arranged linearly when the louver window is closed. In either case, as disclosed in Japanese Utility Model Application Laid-Open No. Sho 56-70083, the right and left sides of the panel are brought into contact with the airtight material provided on the vertical frame by holding the right and left holders of the panel. It has a structure that closes the gap between the end and the vertical frame.

[0003]

Among the above-mentioned conventional louver windows, in the former case where the panel is closed in an inclined posture, the panel assembly has a zigzag structure when viewed from the side. Since the airtight material is applied to the side of the zigzag holder, a gap is easily created between the airtight material and the holder, and air inside and outside of the room communicates through the gap between the holder and the panel to provide airtightness. There is a problem of impairing the performance.

In the latter case, Japanese Utility Model Application Publication No.
As disclosed in No. 3, even if the airtight material attached to the vertical frame is applied to the indoor side surface of the holder, due to the play between the panel and the holder, the gap between the holder and the airtight material, and It is easy to create a gap between the upper and lower panels,
As in the former case, when there is a gap between the holder and the panel, the inside and outside air can easily communicate through the gap, and there is a point to be improved in terms of airtightness.

[0005] In view of the above problems, the present invention can prevent a decrease in airtightness due to a gap between a frame and a panel and between panels, and as a result, a louver with improved heat insulation. The purpose is to provide windows.

[0006]

According to the present invention, in order to achieve the above object, an elastic member is provided between a panel and a holder for holding an end portion of the panel, the elastic member pressing the panel toward a room.
The panel continues linearly up and down when the louver window is closed,
And a structure in which an airtight material provided at an end of one of the opposite panels of the vertically adjacent panel is brought into contact with an airtight material provided at an end of the other panel or an end of the other panel. In the frame, when the window is closed, a position regulating portion is provided for abutting the panel surfaces inside from the left and right ends of the panel to align the panel surfaces of the panels, and the vertical frame is provided inside the left and right ends of the panel when the window is closed. An airtight material for contacting the panel surface is provided, between the upper frame and the uppermost panel of the louver window, and between the lower frame and the lowermost panel of the louver window, respectively, between the frame and the panel when the louver window is closed. Characterized in that an airtight material for closing the gap is provided in the lateral direction. (Claim 1).

Further, the present invention is characterized in that the position restricting portion also functions as an airtight material by using a highly rigid elastic material as the position restricting portion.

[0008]

According to the first aspect, when the louver window is closed,
When the panel surface on the indoor side of the panel is brought into direct contact with the position regulating section provided in the vertical frame, and furthermore, the panel is moved in the closing direction,
Since the holder moves toward the indoor side and the elastic material between the holder and the panel is compressed, errors in assembling the holder and the opening and closing mechanism of the plurality of panels arranged vertically,
Alternatively, an error in assembling each panel and the holder is absorbed, and the panel surfaces of all the panels are aligned. Therefore, the airtight members vertically adjacent to each other are in close contact with each other, and the airtightness between the upper and lower panels is improved.

Further, since the hermetic member is brought into contact with the panel having a uniform panel surface, the hermeticity is improved as compared with the conventional structure in which the holder is brought into contact with the hermetic material. And even if there is a gap between the holders at both ends of the adjacent panel and the panel, the panels arranged in a straight line and the airtight material are more closely attached at the center side than the end of the panel, Airtightness is ensured.

In the second aspect, the position restricting portion itself has elasticity, so that the position restricting portion also has a function as an airtight material.
