Description

  The present invention relates to a remodeled resin sash obtained by remodeling an existing resin sash attached to a building frame to a new resin sash and a method for remodeling the same.

  As disclosed in Patent Document 1, the existing sash that has been attached to the existing building sash is converted into a new sash. A refurbished sash with a frame is known.

Japanese Patent Laid-Open No. 61-229086

The above-mentioned conventional refurbished sash is made of aluminum and the new frame is a renovated aluminum sash, so the existing frame, the upper frame of the new frame, the vertical dimension of the lower frame, the left and right vertical frames Even if the size in the left-right direction, that is, the finding size is reduced, there is no problem in strength.
In addition, the finding dimensions of the upper frame, the lower frame, and the vertical frame are different values depending on the function of each frame.
Thus, the above-described refurbished aluminum sash does not reduce the opening of the new frame even if the new frame is attached inside the existing frame.

However, in the case of a renovated resin sash in which a new resin sash is installed in the existing resin frame and the existing resin sash is remodeled to the new resin sash, the opening of the new resin frame becomes small.
That is, the found dimensions of the existing resin frame, the upper frame, the lower frame, and the left and right vertical frames of the new resin frame are large in strength. For example, since the strength is increased as a shape having a rectangular hollow portion, the finding size is large.
In addition, since the upper frame, the lower frame, and the vertical frame made of resin have a longitudinal end of 45 ° and are joined by being abutted and joined, the upper frame, the lower frame, and the vertical frame have the same cross-sectional shape. The finding dimensions of the upper frame, the lower frame, and the vertical frame are values that match the frame having the largest finding dimension in terms of function.

For this reason, the opening of the modified resin sash in which the new resin frame of the new resin sash is attached in the existing resin frame of the existing resin sash becomes small.
In particular, when the existing resin sash is equipped with a shoji that opens and closes indoors and outdoors, such as an outside window, an inside window, a protruding window, a sliding window, an outside window, and an inside window, the upper frame, The frame and the left and right vertical frames have door contact members on the inner surface, and in the case of sashes, the upper frame, the lower frame, and the left and right vertical frames on the inner surface in the direction of the glass support member Since the upper resin, the lower frame, and the vertical frame of the new resin frame are in contact with the door stop member and the glass support member, a large gap is formed between the new resin frame and the existing resin frame. The opening of will be very small.

  An object of the present invention is a modified resin sash in which a new resin frame of a new resin sash is mounted in an existing resin frame of an existing resin sash provided with a shoji that is closed or moved in an indoor / outdoor direction, and the opening Is a remodeled resin sash that can be made as large as possible and a method for remodeling it.

The refurbished resin sash of the present invention is a glass support member or door provided on the inner surface of the opening of the existing resin sash provided with a shoji that is closed to the inside or outside of the building. The inward projection that becomes the contact member is removed,
In the opening of the existing resin frame, the new resin frame of the new resin sash is attached so as to cover the removed portion of the inward projection.

The refurbished resin sash of the present invention is such that the outdoor side portion of the existing resin frame protrudes to the outdoor side from the outdoor side surface of the new resin frame, and an attachment frame is attached to the outdoor side portion, and the attachment frame is attached to the attachment frame. It can be set as the renovated resin sash to which the resin-made cover material is attached and has covered the outdoor side surface of the said existing resin frame.
In this way, there is no need for airtightness and watertightness between the new resin frame and the building frame.
In addition, since the outdoor side of the existing resin frame is covered with a resin cover material and is not visible from the outside, the new resin frame and the cover material can be seen integrally, so that the appearance of the modified resin sash is good.

In the refurbished resin sash of the present invention, the attachment frame has a rectangular frame shape with an upper attachment, a lower attachment, and left and right vertical attachments, each having a horizontal plate that faces the prospective direction and a vertical plate that faces the finding direction. Is fixed to the outer surface of the existing upper frame, the existing lower frame, and the existing vertical frame of the existing resin frame, and each horizontal plate is attached so as to cover the outside of the inner side surface of each of the existing frames,
A refurbished resin sash having an upper cover, a lower cover, and a vertical cover attached to each vertical plate can be used.
In this way, the attachment frame can be easily attached.
In addition, the horizontal plate of the attachment frame can make the outer side of the existing upper frame, the existing lower frame, and the existing vertical frame projecting from the new resin frame on the inner surface of the attachment frame invisible.

In the refurbished resin sash of the present invention, the outer surface of the new lower frame of the new resin frame is in contact with the inner surface of the existing lower frame of the existing resin frame, and the outer surface of the new lower frame and the lower attachment of the attachment frame Airtight / watertight material is provided between the horizontal plate and airtight, watertight,
There is a gap between the new upper frame of the new resin frame, the outer side surface of the new vertical frame and the existing upper frame of the existing resin frame, the inner side surface of the existing vertical frame,
An airtight / watertight material is provided in each of the gaps to provide an airtight and watertight modified resin sash.
In this way, the new resin frame can be smoothly inserted into the opening of the existing resin frame using the outer surface of the new lower frame as a guide and the inner surface of the existing lower frame.
In addition, the existing resin frame, the attachment frame, and the newly installed resin frame can be airtight and watertight.

The refurbished resin sash of the present invention is such that the upper attachment, the lower attachment, and the vertical attachment horizontal plate are provided with a vertical plate on the outdoor side, and the length can be adjusted by cutting the indoor side. The refurbished resin sash can be used.
If it does in this way, it can attach to the existing resin frame from which a prospective dimension differs by adjusting the prospective dimension of an attachment frame corresponding to the existing resin frame from which a prospective dimension differs.

The refurbishment method of the present invention leaves the existing resin frame of the existing resin sash provided with the shoji that is closed or moved in the indoor or outdoor direction to the building frame,
Removing the inward projections which are provided on the inner surface of the opening of the remaining existing resin frame and serve as a glass support member or a door stop member;
After this, the new resin frame of the new resin sash is moved in the expected direction and inserted into the opening of the existing resin frame,
A method of remodeling an existing resin sash into a new resin sash, wherein the new resin sash is fixed and attached to an opening of the existing resin frame so as to cover a removed portion of the inward projection.

According to the remodeled resin sash of the present invention, the remodeled resin sash is formed by attaching the new resin frame of the new resin sash to the existing resin of the existing resin sash provided with a shoji that is closed or moved in and out of the room. Can do.
In addition, since the inward projections in the opening of the existing resin frame have been removed, the new resin frame has the same height and left and right width dimensions as the opening and left and right width dimensions of the existing resin frame. The opening of the resin frame can be made as large as possible.
Furthermore, since the part from which the inward projection is removed is not visible, the appearance is good.

It is a longitudinal cross-sectional view of the existing resin frame of the state which removed the cover material, the attachment frame, and the newly installed resin frame. It is a cross-sectional view of an existing resin frame in a state where a cover material, an attachment frame, and a new resin frame are removed. It is a longitudinal cross-sectional view in a state where each inward projection is removed. It is a transverse cross section of the state where each inward projection was removed. It is a longitudinal cross-sectional view of a state where a new resin frame is attached. It is a cross-sectional view of a state where a new resin frame is attached. It is a longitudinal cross-sectional view of a modified resin sash. It is a cross-sectional view of a modified resin sash

As shown in FIG. 1 and FIG. 2, the existing resin frame of the existing resin sash equipped with the shoji that is killed by fitting or moved in and out of the room is composed of an existing upper frame 1, an existing lower frame 2, and left and right existing Vertical frames 3 and 3 are provided.
The existing upper frame 1, the existing lower frame 2, and the existing vertical frame 3 have the same cross-sectional shape, and have a hollow shape having a hollow portion in order to obtain high strength. The outer side faces 1a, 2a, 3a and the inner side faces 1b, 2b, 3b in the direction of finding are spaced apart in the direction of finding and have a large finding size.
Each inner side surface 1b, 2b, 3b serves as an opening of an existing resin frame.
The finding direction is a direction in the vertical direction in the existing upper frame 1 and the existing lower frame 2, and a direction in the horizontal direction in the existing vertical frame 3, which is called an in-plane direction.
The indoor side surfaces 1c, 2c, 3c and the outdoor side surfaces 1d, 2d, 3d of the existing upper frame 1, the existing lower frame 2, and the existing vertical frame 3 are separated from each other in the prospective direction, and these surfaces are surrounded by the surfaces. The part has a hollow part.
The prospective direction is a direction toward the indoor outside direction, which is a direction perpendicular to the above-described finding direction, and is referred to as an out-of-plane direction.

On the indoor side surfaces 1c, 2c, 3c of the existing upper frame 1, the existing lower frame 2, and the existing vertical frame 3, the first housing mounting pieces 10, 20, 30 heading toward the indoor side in the prospective direction, and the outer side in the finding direction It has the 2nd housing attachment pieces 11,21,31 which go to.
The first housing mounting pieces 10, 20, and 30 are fixed to the opening 4a of the building housing 4, and the second housing mounting pieces 11, 21, and 31 are fixed to the outdoor side surface 4b of the building housing 4, and the existing resin frame Is attached to the building housing 4. The attachment of the existing resin frame to the building housing 4 is not limited to the above, and can be arbitrarily attached.

On the inner side surfaces 1b, 2b, 3b of the existing upper frame 1, the existing lower frame 2, and the existing vertical frame 3 (that is, the inner surface of the opening of the existing resin frame), inward projections 12, 22, 32.
The inward projections 12, 22, and 32 are formed by an existing resin sash that opens and closes an unillustrated shoji (not shown) on the existing resin frame in an indoor / outdoor direction. In the case of a sash such as a fall window or an inside fall window, it is a door stop member, and in the case of a fitting sash provided with a glass (not shown) fixed to an existing resin frame, it is a glass support member.
By reinforcing the hollow portion by inserting a reinforcing metal material, the strength of each resin frame is increased, but the reinforcing metal material is not inserted into the inward projections 12, 22, and 32 described above. It is.

As shown in FIGS. 1 and 2, the new resin frame of the new resin sash according to this embodiment includes a resin-made new upper frame 5, a new lower frame 6, and left and right new vertical frames 7 and 7.
The new upper frame 5, the new lower frame 6, and the new vertical frame 7 have the same cross-sectional shape, and have a hollow shape with a hollow portion in order to obtain a large strength.
The outer side surfaces 5a, 6a, 7a and the inner side surfaces 5b, 6b, 7b in the direction of finding each new frame are spaced apart in the direction of finding and have a large size.
These inner side surfaces 5b, 6b, and 7b serve as openings for the newly installed resin frame.
The indoor side surfaces 5c, 6c, and 7c and the outdoor side surfaces 5d, 6d, and 7d of each of the newly installed frames are spaced apart in the prospective direction, and have a hollow portion in a portion surrounded by these surfaces and the surfaces.
On the indoor side surfaces 5c, 6c, and 7c of each of the new installation frames, there are housing mounting pieces 50, 60, and 70 facing the indoor side in the prospective direction.

The dimension between the outer surface 5a of the new upper frame 5 and the outer surface 6a of the new lower frame 6 (height dimension of the new resin frame) is the same as the inner surface 1b of the existing upper frame 1 and the existing lower frame 2. It is slightly smaller than the dimension between the side surface 2b (the height dimension of the opening of the existing resin frame) and is almost the same.
The dimension between the outer side surfaces 7a of the left and right new vertical frames 7 (the horizontal width dimension of the new resin frame) is larger than the dimension between the inner side surfaces 3b of the left and right existing vertical frames 3 (opening left and right width dimension of the existing resin frame). Are slightly smaller and almost identical.

Next, the remodeling method will be described.
The shoji and glass (not shown) are removed from the existing resin frame, and the existing resin frame remains in the building housing 4 as shown in FIGS.
The inward projections 12, 22, and 32 of the remaining existing upper frame 1, existing lower frame 2, and existing vertical frame 3 are removed by cutting or the like as shown in FIGS.

The new resin frame is moved in the prospective direction and inserted into the opening of the existing resin frame. For example, it moves from the outdoor side of the existing resin frame toward the indoor side and is inserted into the opening of the existing resin frame. Of course, it may be inserted by moving from the indoor side to the outdoor side.
Then, as shown in FIGS. 5 and 6, the newly installed resin frame is positioned in the prospective direction to cover the portions where the inward projections 12, 22, and 32 are removed, and are fixedly attached to the building frame 4.
For example, the frame attachment pieces 50, 60, 70 are fixedly attached to the opening 4 a of the building frame 4 with the fixing tools 51, 61, 71.
After this, a shoji or glass is attached to the newly installed resin frame to make a modified resin sash.

  Thus, since the inward projections 12, 22, 32 provided on the inner side surfaces 1b, 2b, 3b of the existing resin frames are removed, the outer surfaces 5a, 6a, 7a of the new frames of the new resin frame are removed. Is made to approach the inner side surface 1b, 2b, 3b (that is, the inner surface of the opening of the existing resin frame) of each existing frame of the existing resin frame regardless of the inward projections 21, 22, 32. The height dimension and the left-right width dimension are substantially the same as the height dimension and the left-right width dimension of the opening of the existing resin frame, and the opening of the new resin frame can be made as large as possible.

  Therefore, the opening of the remodeled resin sash in which the new resin frame of the new resin sash is installed in the existing resin frame of the existing resin sash provided with the shoji that is closed or moved in the indoor / outdoor direction can be made as large as possible.

Next, each member will be described in detail.
As shown in FIGS. 1 and 2, each existing frame of the existing resin frame has the inward projections 12, 22, 32 on the inner side of the prospective direction of the inner side surfaces 1b, 2b, 3b. And inwardly facing pieces 13, 23, 33 on the outside of the prospective direction.
In the case of a sash having a shoji that opens and closes indoors and outdoors, the inwardly facing pieces 13, 23, and 33 become a door-to-door portion on the outdoor side where the outdoor side of the shoji contacts. The inward projections 12, 22, and 32 serve as indoor door ends where the indoor side of the shoji is in contact.
In the case where the existing resin sash is a fitting sash, it becomes a locking piece for locking the ledge holding the glass.

As shown in FIGS. 5 and 6, the outdoor side surfaces of the existing resin frames (outer side surfaces 1d, 2d, 3d of the existing frames) are the outdoor side surfaces of the new resin frames (outer side surfaces 5d, 6d, 7d of the new frames). The portion closer to the outdoor side of the existing resin frame is closer to the outside of the prospective direction than the new resin frame.
The airtightness and watertightness between the existing resin frame and the building housing 4 are left as they are.
Since it is like this, it is not necessary to make airtight and watertight between the newly installed resin frame and the building housing 4.

However, as described above, when the portion closer to the outdoor side of the existing resin frame protrudes to the outdoor side than the outer side surface of the new resin frame, the portion closer to the outdoor side of the existing resin frame can be seen from the outside. Because it looks different from the frame, it looks bad.
Therefore, as shown in FIGS. 7 and 8, an attachment frame 8 is attached to the outdoor portion of the existing resin frame, a cover member 9 is attached to the attachment frame 8, and the outdoor side surface of the existing resin frame (the outdoor side surface 1d of each existing frame). , 2d, 3d) are not visible from the outside.

As shown in FIGS. 1 and 2, the attachment frame 8 has a rectangular frame shape with an upper attachment 80, a lower attachment 81, and left and right vertical attachments 82.
The upper, lower, and vertical attachments 80, 81, and 82 are L-shaped with a horizontal plate 83 that faces the prospective direction and a vertical plate 84 that faces the direction of finding, and a pair of locking pieces at both ends of the vertical plate 84 in the direction of finding. 85 is provided toward the outdoor side in the prospective direction, and the pair of locking pieces 85 form a resin cover mounting portion.
The horizontal plate 83 is formed with screw holes 86, the left and right vertical attachments 82 are in contact with both longitudinal end faces of the upper and lower attachments 80, 81, and the screws 87 are connected to the upper and lower attachments 80, 81 from the vertical attachment 82. The upper, lower, and vertical attachments 80, 81, and 82 are connected to the screw holes 86 in a square shape.
The horizontal plate 83 of the upper, lower, and vertical attachments 80, 81, 82 has a plurality of cutting grooves 83a spaced apart in the prospective direction at the interior side portion thereof, and the length of the horizontal plate 83 is increased. It can be adjusted.
The material of the attachment frame 8 may be aluminum or resin, but resin is preferable from the viewpoint of appearance.

The cover material 9 includes an upper cover 90, a lower cover 91, and left and right vertical covers 92, and is engaged with and attached to a pair of locking pieces 85 of the upper, lower, and vertical attachments 80, 81, and 82.
This cover material 9 is made of resin.

Next, the remodeling method will be described in detail.
As shown in FIG. 1 and FIG. 2, each existing frame of the existing resin frame has a stepped inner side surface 1b, 2b, 3c and is located inward of the portion closer to the indoor side where the inward projections 12, 22, 32 are provided. A portion closer to the outdoor side provided with the facing pieces 13, 23, and 33 is positioned outside in the direction of finding, and the inwardly facing pieces 13, 23, and 33 do not get in the way when the new resin frame is inserted.
However, when attaching the attachment frame 8 described above, the inwardly facing pieces 13, 23, 33 are obstructive.

Thus, as shown in FIGS. 3 and 4, when the inward projections 12, 22, 32 are removed by cutting or the like, the inward pieces 13, 23, 33 are removed by cutting or the like.
Since the reinforcing metal material is not inserted into the inward projections 12, 22, and 32, only the resin material can be removed by cutting or the like.
For example, cutting with a jig that melts and cuts by heat does not generate chips, dust, or noise, and does not cause discomfort to residents of the building to be renovated and neighbors.
The removal of the inward pieces 13, 23, 33 by cutting or the like is the same.

  As a jig for melting and cutting by heat as described above, when a voltage is applied, the built-in ceramic vibrator starts to vibrate, ultrasonic waves are generated, an ultrasonic cutter that amplifies this ultrasonic wave with a horn and vibrates the cutting tool, A jig of the type that generates heat is used.

The inward projection 22 of the existing lower frame 2 cuts the vicinity of the base of the inward projection 22 so that the cut portion is flush with the inner side surface 2b. The direction protrusions 12 and 32 may be cut so that portions slightly protruding from the inner side surfaces 1b and 3b remain.
The inward pieces 13, 23, 33 may be cut to such a length that the horizontal plates 83 (screw holes 86) of the attachment frame 8 do not interfere with each other.

A new resin frame is attached as shown in FIGS.
At this time, the outer side surface 6a of the new lower frame 6 is in contact with the inner side surface 2b of the existing lower frame 2, and there is a gap between the outer side surface 5a of the new upper frame 5 and the inner side surface 1b of the existing upper frame 1. There is a gap between the outer side surface 7a of the new vertical frame 7 and the inner side surface 3b of the existing vertical frame 3.
Thus, the new resin frame can be smoothly inserted into the opening of the existing resin frame using the inner side surface 2b of the existing lower frame 2 as a guide.

The frame attachment piece 50 of the new upper frame 5 is in contact with the upper decorative material 40 provided in the opening 4 a of the building frame 4 through the block 52 and the spacer 53.
The frame attachment piece 60 of the new lower frame 6 is in contact with the lower decorative material 41 provided in the opening 4 a of the building frame 4 via the spacer 62.
The frame attachment piece 70 of the new vertical frame 7 is in contact with the vertical decorative material 42 provided in the opening 4 a of the building frame 4 through the block 72 and the spacer 73.

As described above, after attaching the newly installed resin frame, the attachment frame 8 is moved from the outdoor side toward the indoor side as shown in FIGS. 84 is in contact with the outside surface of the existing resin frame (the outside surface 1d, 2d, 3d of the existing upper frame 1, the existing lower frame 2, and the existing vertical frame 3), and is fixed with screws 88. A space between the outdoor side surfaces 1 d and 3 d of the existing upper frame 1 and the existing vertical frame 3 and the vertical plate 84 is water-tight with a sealing material 89.
At this time, the interior side portion of the horizontal plate 83 of the upper, lower and vertical attachments 80, 81, 82 of the attachment frame 8 is cut by the concave groove 83a to adjust the length, and the horizontal plate 83 is attached to each existing frame. The inner side surfaces 1b, 2b, and 3b are in contact with the stepped portions.
Since it is like this, the attachment frame 8 can be attached to the existing resin frame from which a prospective dimension differs.

An upper cover 90, a lower cover 91, and a vertical cover 92 are attached to the upper, lower, and vertical attachments 80, 81, and 82 of the attachment frame 8, respectively, and watertight and airtight treatments are performed.
For example, between the inner surface 1b of the existing upper frame 1 and the outer surface 5a of the new upper frame 5, between the horizontal plate 83 of the lower attachment 81 and the outer surface 6a of the new lower frame 6, the inner surface of the existing vertical frame 3 Airtight and watertight materials 14, 24, 34 on the indoor side and airtight watertight materials 15, 25, 35 on the outdoor side are provided between 3 b and the outer surface 7 a of the newly installed vertical frame 7, respectively, so as to be airtight and watertight.
The indoor airtight and watertight materials 14, 24, and 34 are dry, the outdoor airtight and watertight materials 15, 25, and 35 are wet, and backup materials 16, 26, and 36 are provided therebetween.
