Description

The present invention relates to a refurbishment fitting provided with a new frame provided in an opening formed by the existing frame.

As a remodeling fitting provided with a new frame provided in the opening formed by the existing frame, for example, a remodeling sash unit provided on the inner peripheral side of the existing frame of the existing sash is known (see Patent Document 1). In this refurbished sash unit, the upper part of the refurbished frame is moved from the indoor side to the outdoor side, and the outdoor surface of the refurbished upper frame is attached to the refurbished upper frame contact portion provided on the existing frame and protruding downward. It is attached to the existing frame by making contact from the inside.

In addition, some of the refurbished sash units as described above move the refurbished frame from the outdoor side to the indoor side and attach it to the existing frame. Such refurbishment fittings are provided on the inner peripheral side of the existing frame, and the refurbished frame is provided with the existing frame and a cover portion covering between the existing frame and the refurbished frame.

Japanese Patent No. 5303498

Depending on the building to be installed, the fittings for renovation may be easier to install from the indoor side or may be easier to install from the outdoor side. When the refurbished sash unit as described above is moved from the indoor side to the outdoor side, the upper part of the refurbished frame is brought into contact with the existing upper frame from the indoor side, so that it can be mounted from the indoor side, but it should be mounted from the outdoor side. I can't. Further, when the refurbished frame is provided with the existing frame and the cover portion covering between the existing frame and the refurbished frame, the maximum vertical and horizontal outer dimensions of the refurbished frame are larger than the maximum vertical and horizontal inner dimensions of the inner circumference of the existing frame. Therefore, it can be installed from the outdoor side, but cannot be installed from the indoor side. For this reason, even at one construction site, fittings that can be attached from the indoor side and fittings that can be attached from the outdoor side must be selected and attached, so there is a need for refurbishment fittings that can be attached from either side. There is.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a refurbishment fitting that can be attached from both the indoor side and the outdoor side.

In order to achieve such an object, the refurbishment fitting of the present invention is a refurbishment fitting provided with a new frame provided in an opening formed by the existing frame, and the outdoor side is between the existing frame and the new frame. The cover member includes a first skeleton fixing portion that can be fixed to the skeleton and a new frame joining portion that is joined to the new frame, and the new frame is formed from the cover member. Is also a fitting for refurbishment characterized by having a second skeleton fixing portion fixed to the skeleton on the indoor side.

According to such refurbishment fittings, the first skeleton fixing portion of the cover member that covers between the existing frame and the new frame from the outdoor side is fixed to the skeleton from the indoor side, and then the new frame is inserted from the indoor side. 2 It is possible to easily attach from the indoor side by fixing the skeleton fixing part to the skeleton and joining the new frame and the cover member, and with the cover member attached to the new frame, attach the new frame to the skeleton from the outdoor side. By fixing it, it can be attached from the outdoor side. Therefore, it is possible to provide refurbishment fittings that can be attached from either the indoor side or the outdoor side.

In such a fitting for refurbishment, the new frame is provided with a frame main body and a connecting member for connecting the frame main body and the cover member to be detachably provided, and the new frame joint portion is provided on the connecting member. It is desirable that the cover joint portion to be joined with the second skeleton fixing portion and the second skeleton fixing portion are provided.

According to such refurbishment fittings, since the new frame is divided into a frame main body and a connecting member, it is possible to form a new frame made of different materials such as synthetic resin and metal, for example. At this time, if the connecting member having the cover joint portion and the second skeleton fixing portion is made of metal and the frame body is made of synthetic resin, it is possible to provide a new frame that can be firmly fixed and has heat insulating properties. Is.

In such a refurbishment fitting, it is desirable that the new frame joint portion and the cover joint portion can be joined from the indoor side.
According to such a refurbishment fitting, since the new frame joint portion and the cover joint portion can be joined from the indoor side, it is possible to provide a refurbishment fitting that is easier to install from the indoor side.

In the refurbishment fitting, the existing frame and the connecting member are made of metal, the new frame is made of synthetic resin, and the cover member is a metal outdoor cover portion arranged on the outdoor side. It is desirable to have a metal indoor cover portion that is arranged on the indoor side and to which the cover joint portion is joined, and that the outdoor cover portion and the indoor cover portion are joined by a relay portion made of synthetic resin. ..

According to such refurbishment fittings, the new synthetic resin frame is thermally cut off from the existing metal frame and the metal interior member of the cover member, so that the refurbishment fitting has high heat insulation. It is possible to provide.

According to the present invention, it is possible to provide a refurbishment fitting that can be attached from either the indoor side or the outdoor side.
