DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refurbishment sash suitable for refurbishment (renovation), and includes a sliding window, a louver window, a sliding window, a sliding window, a casement window, a FIX window, a raising and lowering window, an inner casement, The present invention relates to a refurbished sash used for various windows such as a casement window.

[0002]

2. Description of the Related Art Conventionally, the type of sash provided in an opening of a building has been changed (for example, a sliding window has been changed to a sliding window, etc.) in accordance with a renovation of a building or a change in use of a room. When replacing a sash due to damage or aging of the window frame, or when replacing the sash to eliminate the inconvenience due to the sound of opening and closing the windows and the inconsistency, attach it directly to the building frame. It was necessary to remove the window sash by partially breaking the outer wall material around the opening of the building. However, if the outer wall material around the opening is broken when replacing the sash, it will be a large-scale operation and costly, so especially for the damage, aging and noise of the window frame, only maintenance such as repair is necessary. Often corresponds.

[0003] For this reason, there is a demand for a sash that can be replaced without breaking the outer wall material. As such a replaceable sash, a frame is fixed to a frame facing an opening of a building.
There is one in which a window frame is brought into contact with the frame body from the outdoor side and screwed. Such a conventional sash is configured such that the window frame can be replaced without breaking the interior and exterior around the opening by attaching and detaching the window frame to and from the frame.

[0004]

By the way, the window frame and the frame of the conventional sash for refurbishment are both formed by a four-frame structure of a window frame and a support frame made of extruded metal members. There are many. However, it is necessary to manufacture the window upper frame, the window lower frame, the left and right window vertical frames, which are the window frame materials of the window frame, and the support upper frame, the lower support frame, and the left and right support vertical frames which are the support frame materials of the support frame. However, since separate extrusion dies are required for each, there is a problem in that the number of dies increases, the dies cost increases, and the cost of the sash increases.

[0005] It is an object of the present invention to provide a remodeling sash which can reduce the number of extrusion dies used for the support frame and reduce the cost.

[0006]

SUMMARY OF THE INVENTION The refurbished sash of the present invention comprises:
A support frame attached to the opening of the building to see through the outer wall material around the opening, and a window frame detachably mounted in the support frame, a support upper frame, a support lower frame, and a support frame constituting the support frame Of the left and right support vertical frames, at least the support upper frame and the support vertical frame have the same extruded shape in cross section , and the window frame is
It is characterized in that it is attached to and detached from the support frame from the indoor side .
It should be noted that having the same cross-sectional shape means that each part has the same dimensions, and therefore does not include a similar shape.

In the present invention, at least the supporting upper frame and the supporting vertical frame of the supporting frame are formed as extruded members having the same sectional shape, so that the supporting upper frame and the supporting vertical frame have a common extrusion die. By reducing the number of the molds, the cost of the sash is reduced. Further, since the outer wall material around the opening is cut off by the support frame, there is no need to break the outer wall material when the window frame is attached to or detached from the support frame, and the remodeling operation can be easily performed.

In the above, the upper supporting frame, the lower supporting frame, and the left and right supporting vertical frames constituting the supporting frame may be formed by extruded members having the same sectional shape. In such a case, the cost of the sash is further reduced because each support frame material constituting the support frame is manufactured by one extrusion die.

On the other hand, only the supporting lower frame constituting the supporting frame is
A rising portion extending upward from the indoor side may be provided.
In such a case, since the rising portion is provided only on the supporting lower frame, the window frame is disposed by being dropped into the supporting lower frame from the indoor side, and is disposed between the supporting lower frame and the window lower frame. Even if rainwater or dew condensation water enters, there is no danger that those water droplets will be stopped by the rising part and enter the room.
The water droplets between the support upper frame and the window upper frame and the water droplets between the support vertical frame and the window vertical frame travel through the support vertical frame and the window vertical frame, and finally, the support lower frame and the window lower portion. Since it flows down between the frame and the frame, there is no need to worry about entering the room even if there is no portion corresponding to the rising portion in the supporting upper frame, the supporting vertical frame, or the like.

Further, in the refurbished sash according to the present invention, the window frame is configured such that a sliding screen is arranged thereon, and the height level of the upper end of the window frame of the window frame is made equal to the floor level of the building. Alternatively, the height level of the upper end of the supporting lower frame may be lower than the floor level. In such a case, the renovation sash will be a so-called barrier-free type sliding window in order to make the height level of the upper end of the window frame the same as the floor level of the building. Can easily enter and exit. The height level of the upper end of the support lower frame is the same as the floor level depending on the specific shape of the support lower frame,
Alternatively, it may be lower and not higher than the floor level.

Further, since the pressing direction of the sealing material 14 and the inserting direction of the window frame 20 are the same, good adhesion of the sealing material 14 can be obtained only by attaching the window frame 20. With these features, the water stopping property in three directions between the support frame 10 and the window frame 20 can be easily improved.

5) In the sliding window 1, the upper end of the rising portion 12B of the supporting lower frame 12, the lower guide rail 22B of the lower window frame 22, and the upper end of the partition 22C have the height level of the building floor. When traveling between indoors and outdoors, for example, a terrace, there is no need to cross or climb over the supporting lower frame 12 or the window lower frame 22. In such cases, it is possible to easily enter and exit from the window 1.

6) In the sliding window 1, the heat insulating material 40 and the pressing member 50 are provided, and the window lower frame 22 is provided.
Even when the outside of the support frame 10 and the window frame 20 is cooled because the indoor member 15 of the support lower frame 12 is not in contact with the indoor member 15 of the support lower frame 12, the indoor member 15, 25 whose cold heat is exposed to the room is cooled.
Is not transmitted to the interior member, so that dew condensation on the indoor members 15 and 25 can be favorably prevented. At this time, in the support frame 10, the heat insulating material 40 is provided only on the lower support frame 12, and in the window frame 20, the heat insulating material 40 is provided only on the window upper frame 21 and the window vertical frame 23. Can be provided at a lower cost than in the case where are provided on the four circumferences of the frames 10 and 20, respectively.

7) By using the holding member 50, aging and construction errors of the support frame 10 can be absorbed, and construction accuracy can be improved.

8) Since the window frame 20 is fixed to the support frame 10 with screws from the inside in the in-plane direction of the opening A, the screws can be made hard to see from inside and outside the room, and the interior appearance of the window 1 is good. Can be.

9) Since the outer wall material 60 around the opening A is cut off by the support frame 10, there is no need to break the outer wall material 60 when the window frame 20 is attached to or detached from the support frame 10, and the remodeling work can be performed. Easy to do
