Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an opening in an external wall with a casement window.

[Conventional technology]

Opening shoji screens for ventilation are sometimes installed on external walls such as curtain walls. In this case, the shoji is fitted into the window frame, but the outdoor surface of the window frame is located outward in all directions from each frame of the shoji, so the window frame is visible from the outside of the room.

[Problem that the invention attempts to solve]

However, when the window frame is exposed to the outside, each frame of the window frame as well as each frame of the shoji screen can be seen from the outside, and a large number of parts are visible from the outside, resulting in an unsightly appearance.

Furthermore, with casement windows, it is essential to provide a tight material between the window frame and the shoji screen to ensure air and water tightness. In this case, in the conventional structure, at least a portion of the tight material is directly exposed to the outside, so it is exposed to direct sunlight, which tends to cause deterioration and spoil the appearance. Furthermore, although some efforts have been made to make the structure watertight, it is not perfect.

Therefore, an object of the present invention is to provide an opening structure that has an outstanding appearance, is highly air- and water-tight, and can prevent the deterioration of the tight material.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention consists of a window frame composed of upper and lower frames and left and right vertical frames, and a window frame that fits into this window frame and is supported so as to be openable and closable, and is composed of upper and lower frames and left and right frames. In an opening in an outer wall equipped with a shoji; each stile forming the four circumferential surfaces of the shoji has a covering flange portion extending to cover the entirety of each frame forming the four circumferential surfaces of the window frame on the outdoor side; However, an outer tight material is provided at least between the upper and left and right sides of the gap between this cover flange and the outdoor side surface of the window frame facing it, without going beyond the edge of the cover flange. 〓Inner tight material is not provided or is provided with a part cut out between them, and inner tight material is provided between the interior side of each stile and the window frame to ensure air and water tightness when the shoji is closed. The space between each stile and the corresponding window frame and surrounded by the outer tight material and the inner tight material is an equal pressure space that communicates with the outside air atmosphere. This is a characteristic feature.

[Effect]

According to the present invention, each stile is formed with a cover flange portion that covers the outdoor surface of each frame of the window frame. Therefore, when viewed from outside, only the shoji screens are visible, and the window frames are not visible, giving the building a clean appearance.
High design effect.

Further, rainwater that attempts to enter between each stile and the window frame is blocked by the cover flange portion, making it difficult for rainwater to enter.

Furthermore, in the present invention, the tight material is provided between the cover flange and the outdoor side surface of the window frame in a part that is hidden by the cover flange. It is not exposed to sunlight and its deterioration is prevented. In addition, the above-mentioned cover flange is located on the outdoor side of the tight material, and the tight material that directly acts on it blocks wind and rain, so there is no deformation of the tight material and there is less stress, resulting in air and water tightness. You can obtain products with excellent properties.
