Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window unit in which an existing window can be remodeled into a new window only by a work from the inside of the room. More specifically, the window opening frame size difference and shape difference between windows are small. However, the present invention relates to a window unit that can be used universally and a window remodeling method using the same.

[0002]

2. Description of the Related Art In the case of old buildings, the window frame is often made of steel, and as a result, there is a risk that the window frame or the like will be corroded and deteriorated due to deterioration over time. Therefore, in order to increase the durability or enhance the appearance, a new window made of aluminum is renovated.

Various methods have been developed and put to practical use as the window remodeling method, but when roughly classified, the old window frame is completely removed and the old window frame is left as it is. It can be divided into two types, one for attaching a window frame.

In the case of these remodeling methods, in order to secure the air / liquid tightness between the new window frame and the frame opening, mortar is filled between the window frame and the frame opening and a molding sealing material is used. However, there is a problem in that a scaffold must be provided on the outside of the room for the form work, the mortar filling work, and the sealing work. In particular, in the case of small windows such as kitchens and toilets, it has been desired from the viewpoint of the construction scale that the renovation work can be performed easily and in a short time from the indoor side without providing a scaffold on the outdoor side.

Therefore, the inventor of the present invention has proposed the above-mentioned Japanese Patent Laid-Open No. 9-49.
In Japanese Patent No. 371, a method has been proposed in which a window can be refurbished easily and in a short period of time while ensuring gas-liquid tightness only by construction from the inside without providing a scaffold on the outside. Specifically, as shown in FIGS. 8 and 9, this remodeling method is performed by anchoring window frame anchors 51A to 51A.
If the old window is removed while D is left, the anchors 51A to 51D for window frames serve as seats, and the fastener members 52A to 52A to project inwardly on the four circumferential surfaces of the frame opening.
52D is attached, and then the upper frame 53A of the window frame 53 and both vertical frames 53C and 53D are respectively tongue-shaped seal members 5 whose tips come into contact with the frame opening prospective surface in the state after remodeling.
Bring in the remodeling window unit 50 with 4, 54 ...
With the inner surface of the window frame of the remodeling window unit 50 in contact with the outer surfaces of the fastener members 52A to 52D, the window frame 53 of the remodeling window unit 50 is viewed from the inside.
And the fastener members 52A to 52D are connected and fixed.

[0006]

In the case of the remodeling window unit 50, instead of the conventional mortar or molded sealing material, the tongue-shaped sealing members 54, 54 ... Preliminarily attached around the window frame are used. Airtight / liquid-tightness, especially watertightness around the window frame is ensured, and the tongue-shaped sealing materials 54, 54 ... Must be in contact with the body opening surface in the installed state.

However, for example, the thickness of the skeleton opening corresponding to the mounting position of the tongue-shaped sealing material 54 is partially reduced, or as shown in the figure, the skeleton opening is inclined toward the outdoor side. Is attached,
In some cases, the tip of the tongue-shaped seal material 54 did not come into contact with the body opening surface.

To solve this problem, the size of the remodeled window unit may be changed according to the shape of each opening, or a plurality of tongue-shaped sealing materials having different lengths may be prepared in advance. Has a problem in that the construction, management and handling are very complicated, and thus the construction is very complicated.

Therefore, the main object of the present invention is to remove the existing window unit and then replace it with a new one.
In a remodeling window unit including a tongue-shaped seal member that comes into contact with the frame opening prospective surface in a state after remodeling, at least on the upper frame outer surface side and the vertical frame outer surface side of the window frame, respectively.
For example, there are some dimensional errors in the shape of the body opening,
Even if there is an inclination toward the outside, it is possible to install with the tip of the tongue-shaped sealing material in contact with the expected opening of the body by a simple and reliable method, and it is flexible to apply the remodeling window unit. Is to improve the workability.
