Description

[Detailed Description of the Invention] This invention relates to a device for attaching a new sash frame to a modified sash of the type in which a new sash is attached to the outdoor side of an old existing sash.

Metal sashes, which are generally highly durable, are susceptible to corrosion due to aging, salt air, acid rain, cement components in the case of sashes installed in concrete buildings, and noise due to environmental changes. Due to growth, replacement may be required. but,
Conventionally, replacing an existing sash with a new sash required very extensive renovation work, which required a lot of time and construction costs, so it was not easy to satisfy the desire for replacement.

In view of the above points, this idea was developed by installing a peripheral material around the outdoor side of the existing sash frame to form an opening for attaching the sash, without removing the existing sash frame, and installing a new sash frame in that opening. By installing it, you can easily construct it using a minimum number of materials, and
The purpose is to enable the renovation of satsui windows without narrowing the window's lighting surface.

In order to achieve the above purpose, firstly, the inner circumferential surface of the existing sash frame is covered, and secondly, the inner circumferential surface of the existing sash frame is coated on the outdoor side of the existing sash frame, and the inner circumferential surface is A peripheral material having a large internal dimension is attached, the peripheral material forms an opening for attaching the sash, and a new sash frame is installed in the opening, thereby providing a lighting area at least equal to or larger than the existing sash frame. This makes it possible to install a new sash frame with a larger lighting area.

Next, various embodiments of this invention will be explained based on the drawings.

FIG. 1 shows an example in which this invention is applied to a satin window of a wooden building. 1 and 2 are the upper and lower frames that constitute the existing sash frame, along with the left and right vertical frames (not shown).
and is fixed to the window sill 4. Further, 5a ₁ is an upper peripheral edge material attached to the outdoor side of the existing sash frame, and is fixed to the outdoor side surface of the lintel 3 by nailing or the like while covering the mounting edge 6 of the upper frame 1. There is. This upper peripheral material _5a1 is approximately L on the upper surface.
shaped, the horizontal part slopes downward toward the outdoors, and
It is provided with a draining plate 7 that extends to the outside from the peripheral material _5a1 , and an upper exterior finishing material 8 is attached to the upper side of the draining plate. _5a2 is the lower peripheral material installed on the outdoor side of the existing sash frame,
It is fixed to the window sill 4 by nailing. The lower peripheral material has a draining plate 9 on its lower surface that slopes downward toward the outdoor side and extends further outdoors than the peripheral material _5a2 , and a lower exterior finishing material 10 is provided on the lower side of the draining plate 9. installed. Although not shown, a vertical edge material similar to the upper edge material _5a1 is fixed to the outdoor side surfaces of the left and right vertical frames via pillars, and a draining board is fixed around the edge material. However, the side exterior finishing material is cut off by the draining board.

To install the new sash frame mounting device according to this invention, first, as described above, a peripheral material is attached around the outdoor side of the existing sash frame, and the peripheral material forms an opening for attaching the sash. The inner dimensions of this peripheral material are set larger than the inner dimensions of the opening of the existing sash frame whose inner peripheral surface is covered.

Next, the new sash frame NS, which has been framed in a square shape in advance, is fitted into the opening formed by the peripheral material, and the mounting wall 1 of the upper frame 11 constituting the new sash frame is fitted.
2 on the outdoor side of the upper peripheral material 5a ₁ , the mounting wall 14 of the lower frame 13 on the outdoor side of the lower peripheral material 5a ₂ , and the mounting walls of the left and right vertical frames (not shown) on the left and right vertical sides. The new sash frame is attached to the surrounding material by, for example, screwing in the screws 15 from each mounting wall while contacting the outdoor side surfaces of the surrounding material. In this case, if the indoor side wall 16 of the new sash frame is brought into contact with the outdoor end of the existing sash frame, positioning can be facilitated and the installation stability of the new sash frame can be improved.

In addition, since the upper draining plate 7 and the new sash upper frame 11 are overlapped vertically, the upper exterior finishing material 8
Rainwater flowing down is first drained outdoors by the draining plate 7 and then further drained by the new sash upper frame, so that water leakage from the attachment part of the new sash upper frame to the indoor side is prevented. Since the lower draining board 9 and the new sash bottom frame 13 are also overlapped vertically, most of the rainwater flowing down from the new sash window surface is discharged outdoors from the outdoor end of the bottom frame, Since the rainwater that has gone around is also removed by the drainage plate 9, water leakage from the new sash lower frame attachment part to the indoor side is prevented. Therefore, rain protection is ensured when attaching a new sash frame to an existing sash frame.

Finally, cover members 17a and 17b are respectively attached to the inner surfaces of the upper frame 1, lower frame 2, and left and right vertical frames (not shown) that constitute the existing sash frame. The upper cover material 17a is the guide groove 18a ₁ , 18 of the upper frame that constitutes the shoji accommodating part of the existing sash frame.
a ₂ , 18 a ₃ and the locking part bent upward at the outdoor end is attached to the upper frame 11 of the new sash frame.
The upper frames 1 and 11 are connected to each other by being secured to the outdoor side surface of the indoor side wall 16 of the frame, and the indoor side end thereof is fixed to the frame material 19 or the indoor side wall 20 of the upper frame 1 of the existing sash frame with screws 21. . The lower cover material 17b also covers the rails 18b ₁ , 18b ₂ , 18b ₃ of the lower frame that constitute the shoji storage part of the existing sash frame, and has a new locking part bent downward at the outdoor end. The lower frame 13 of the sash frame is engaged with the outdoor side surface of the rain return wall 22, and the indoor end portion is fixed to the window sill 4 with screws 21 to connect the lower frames 2 and 13. In the same way, the left and right vertical sides of the covering material cover the door stop groove of the vertical frame that constitutes the shoji storage part of the existing sash frame, and are fixed to the vertical frame material or pillars to connect the vertical frame of the existing sash frame to the new one. It connects the vertical frame of the Satsushi frame. In this way, the inner peripheral surface of the existing sash frame is covered with the cover material, and the existing sash frame and the new sash frame are connected.

As described above, a new sash frame is installed on the outdoor side of the existing sash frame, shoji d ₁ and d ₂ are installed on this, and the sash is renovated.

23 is the rain return wall 16 of the lower frame 13 of the new satsushi frame
This is a connecting edge protruding toward the indoor direction from the bottom, and is engaged with a rail _18b2 of the lower frame of the existing sash frame on the lower side of the lower cover member 17b. When attaching a new sash frame, lock this connecting edge to the rail,
Since the relative movement of both lower frames is prevented, it is easy to attach the cover material 17b, and the connecting edge 23
works as follows. In other words, depending on the form of the surrounding material, as shown in the example in Figure 1, the new sash frame will be installed in the same way as an external sash frame, and the load of the shoji or screen door installed on the new sash frame will be transferred to the lower frame. However, the connecting edge 32 reinforces the load-bearing strength of the lower frame 13.

In addition, the existing sash lower frame 2 is a lower cover material 17b.
Since it is covered with , it can be used as a stand for small items. Or, instead of this,
By attaching a blind box to the lower surface of the upper cover material 17a, a Venetian blind can be installed using the space of the existing sash frame.

As mentioned above, according to this invention, a peripheral material is installed around the outdoor side of the existing sash frame, an opening for installing the sash is formed by the peripheral material, and a new sash frame is installed in the opening, thereby making it possible to remodel the existing sash frame. Since a sash window can be obtained, there is no need to remove the old existing sash frame, and the sash renovation work can be carried out extremely easily and in a short time.

In addition, since the opening for attaching the sash is formed using a peripheral material that has an inner dimension larger than that of the existing sash frame whose inner circumferential surface is covered, and the new sash frame is attached to the opening, the window is illuminated. A sash window can be renewed without making the area narrower than the existing sash frame.

Furthermore, draining boards are provided on the upper surface of the upper peripheral material and the lower surface of the lower peripheral material, each of which slopes downward toward the outdoor side and extends beyond each peripheral material to the outdoor side, and the upper drainage board and the new sash upper frame are provided. Since the lower draining board and the new sash bottom frame are overlapped vertically, when installing the new sash on the outdoor side of the existing sash, rainwater can be drained outdoors using the upper draining board on the upper frame side. In addition, on the lower frame side, rainwater that falls from the lower frame is discharged outdoors by the lower drainage plate, thereby preventing water leakage to the frame side.

In addition, the existing sash frame can be effectively utilized for storing blinds or storing small items.
