Japanese Patent Publication No. 64-5156

Like the conventional modified sash described above, an engagement receiving piece having an engagement receiving portion is provided on the indoor side of the new upper frame and the new vertical frame, and an engagement piece having an engagement portion is provided on the cover material. If the cover member is attached by engaging the engaging portion and the engagement receiving portion by pushing the engaging piece into the engagement receiving piece, the cover material can be easily attached.
The cover material described above is generally an aluminum cover material obtained by extrusion molding of an aluminum material, but recently a resin cover material obtained by extrusion molding of a synthetic resin material may be attached to prevent condensation.
Since the engagement piece of the aluminum cover material is harder to be elastically deformed than the engagement piece of the resin cover material, it is necessary to make the engagement piece long and easy to push in. Lengthens to match the piece.
For this reason, when a resin cover material is attached instead of the aluminum cover material, the length of the engagement piece becomes longer in accordance with the length of the engagement receiving piece. Since the shape is difficult to stabilize during extrusion molding, the attachment of the resin cover material becomes unstable.
To solve this problem, the engagement piece of the resin cover material may be shortened. However, since the engagement receiving piece is short in this way, the engagement piece is elastically deformed when the cover material is made of aluminum. It is difficult to attach the aluminum cover material.

  An object of the present invention is to provide a modified sash that can easily attach an aluminum cover material to the indoor side portion of a newly installed upper frame and a newly installed vertical frame and can stably attach a resin cover material. .

The present invention is a repair sash in which an existing sash attached to an opening of a building frame is modified to a new sash, and a cover material is attached to the indoor side of the new upper frame and the indoor side of the new vertical frame,
On the indoor side of the new upper frame and the indoor side of the new vertical frame, there is a pair of engagement receiving pieces spaced in the in-plane direction toward the indoor side in the out-of-plane direction. A first engagement receiving portion near the outdoor side in the out-of-plane direction, and a second engagement receiving portion near the indoor side in the out-of-plane direction,
Each of the cover members has a main body and a first pair of engagement pieces provided on the main body toward the outer side in the out-of-plane direction and having an engagement portion that engages with the first engagement receiving portion. And a second cover having a pair of engaging pieces provided on the main body toward the outer side in the out-of-plane direction and having an engaging portion that engages with the second engaging receiving portion. It is a repair sash characterized by being made of wood.

In the present invention, when the engaging portion engages with the first engagement receiving portion or the second engagement receiving portion, the main body of the cover material can be brought into contact with the distal end surface of the engagement receiving piece.
If it does in this way, a cover material can be positioned and attached to an out-of-plane direction by attaching so that it may push in until the main body contacts the front end surface of an engagement receiving piece.

In the present invention, the pair of engagement receiving pieces are provided with a first engagement receiving portion and a second engagement receiving portion facing each other in the in-plane direction on the inner surface, and the surface of the second engagement receiving portion. The second interval in the inward direction is larger than the first interval in the in-plane direction of the first engagement receiving portion;
The fourth interval between the engagement portions of the pair of engagement pieces of the second cover material is larger than the third interval in the in-plane direction between the engagement portions of the pair of engagement pieces of the first cover material, The third interval may be larger than the first interval and smaller than the second interval, and the fourth interval may be larger than the second interval.
According to this configuration, when the cover member having the long engagement piece is attached, the engagement portion exceeds the second engagement receiving portion without interfering with the second engagement receiving portion. The cover member having a long engagement piece can be correctly attached.

In this invention, the cover member includes a engaging piece attaching section toward the plane direction, the cover portion toward the exterior side of the out-direction provided in-plane direction inside the engagement piece mounting part, the engagement It has a cover part that is continuous with the outer side in the in-plane direction of the piece mounting part , and an airtight material is attached to the cover part toward the outdoor side,
With the cover material attached, the tip of the cover portion is in contact with the indoor side of the new upper frame and the new vertical frame, and the airtight material is in contact with the indoor side of the existing upper frame and the existing vertical frame. it can.
By doing this, the engagement receiving piece and the engagement piece cannot be seen from the indoor side, so that the interior appearance is good.

In the present invention, the second cover material has a recess at the tip of the cover,
This recessed part can be fitted to the protrusion provided on the indoor side part of the new upper frame and the new vertical frame.
In this way, warping in the in-plane direction of the cover portion of the resin cover material can be prevented.

In the present invention, the airtight member may have an attachment portion and a fin portion, and the fin portion may be formed of a soft material.
In this way, when the new sash frame is pulled by the strong wind, etc., and the new sash frame is pulled outside, the fins of the airtight material are elastically deformed, and the cover material is Since it moves to the outdoor side together with the vertical frame, the engagement receiving part and the engagement part do not come off, and the cover material does not come off from the new upper frame and the new vertical frame.

According to the present invention, since the first cover member having the engagement piece provided with the engagement portion that engages with the first engagement receiving portion, the pair of engagement pieces is long and easily elastically deformed. Even when the cover material is made of aluminum, the pair of engaging pieces can be easily pushed into the pair of engaging receiving pieces to engage the engaging portions with the engaging receiving portions. Aluminum cover can be easily attached to the indoor side.
If the cover material is a second cover material having an engagement piece with an engagement portion that engages with the second engagement receiving portion, the pair of engagement pieces may be too short and elastically deformed. In addition, since the shape is stable during extrusion molding, the cover material can be stably attached even when the cover material is made of resin, and the resin cover material can be stably attached to the indoor side portions of the new upper frame and the new vertical frame.

In short, it may be a repaired sash obtained by repairing an existing sash attached to the opening 1a of the building housing 1 into a new sash.

The cover material 8 is attached to the indoor side portion 30a of the new upper frame 30. This cover material 8 faces the indoor side portion 20a of the existing upper frame 20, closes the gap between the existing upper frame 20 and the new upper frame 30, so that the base material 5, the spacer 6 and the like cannot be seen from the indoor side. It is.
The cover material 8 is also attached to the indoor side portion 32a of the new vertical frame 32. This cover material 8 faces the indoor side portion 22a of the existing vertical frame 22 and closes the gap between the existing vertical frame 22 and the new vertical frame 32 so that the base material 5, the spacer 6 and the like cannot be seen from the indoor side. I have to.

Next, attachment of the cover material 8 will be described.
As shown in FIG. 3, a pair of engagement receiving pieces 40, 40 are integrally provided on the indoor side portion 30 a of the new upper frame 30 toward the indoor side in the out-of-plane direction. The pair of engagement receiving pieces 40, 40 are spaced apart in the in-plane direction (vertical direction).
Each of the engagement receiving pieces 40 has a first engagement receiving portion 41 and a second engagement receiving portion 42, and the first engagement receiving portion 41 is closer to the outdoor side in the out-of-plane direction. The receiving part 42 is separated in the out-of-plane direction so as to be closer to the indoor side in the out-of-plane direction.

The cover member 8 has a main body 50 and a pair of engaging pieces 51 provided on the main body 50, and each engaging piece 51 has an engaging portion 52.
The length of the engaging piece 51 (distance from the main body 50 to the engaging portion 52) is such that when the main body 50 comes into contact with the distal end surfaces of the pair of engaging receiving pieces 40, the engaging portion 52 is first. The length is engaged with the engagement receiving portion 41.

The cover member 8 is pushed toward the outdoor side, and the pair of engagement pieces 51 are pushed into the pair of engagement receiving pieces 40, whereby the engaging portion 52 and the first engagement receiving portion 41 are engaged with each other. 8 can be attached to the indoor side portion 30 a of the newly installed upper frame 30.
Since it is like this, since the length of the engagement piece 51 of the cover material 8 is longer than the length of the engagement piece which the engaging part 52 engages with the 2nd engagement receiving part 42, the cover material 8 is used. When aluminum is used, for example, even when an aluminum extruded shape is used, the cover material 8 can be easily attached.
Moreover, since the cover member 8 is positioned in the out-of-plane direction when the main body 50 is in contact with the front end surfaces of the pair of engagement receiving pieces 40, the cover member 8 can be positioned and attached by being pushed in.

As shown in FIG. 4, the cover material 8 attached to the indoor side portion 32a of the new vertical frame 32 has the same shape as the cover material 8 attached to the indoor side portion 20a of the new upper frame 20, and is attached in the same manner. .
In other words, the pair of engagement receiving pieces 40, 40 are provided in the indoor side portion 32 a of the newly installed vertical frame 32 so as to be separated in the in-plane direction (left-right direction), and the pair of engagement pieces 51 of the cover material 8 are engaged. The part 52 is engaged with and attached to the first engagement receiving part 41.

5 and 6 are sectional views in which the resin cover material 8 is attached to the indoor side portions 30a and 32a of the new upper frame 30 and the new vertical frame 32. The new upper frame 30 and the new vertical frame 32 are the above-mentioned figures. It is the same as the newly installed upper frame 30 and the newly installed vertical frame 32 shown in FIGS.
The cover member 8 is the same as the cover member 8 shown in FIGS. 3 and 4 described above in that a pair of engagement receiving pieces 51 are provided on the main body 50. However, the length of the pair of engagement pieces 51 (main body) (Distance from 50 to the engaging portion 52) is shorter than the length of the engaging piece 51 described above, and the engaging portion 52 is engaged with the second engagement receiving portion 42.

  Thus, the length of the pair of engaging pieces 51 of the cover material 8 is short, and even if it is a resin cover material, the engaging pieces 51 are not excessively elastically deformed, and the shape is formed during extrusion molding. Therefore, the resin cover material 8 can be stably attached to the indoor side portions 30a and 32a of the newly installed upper frame 30 and the newly installed vertical frame 32.

As shown in FIGS. 3 to 6, the pair of engagement receiving pieces 40, 40 includes a first engagement receiving piece 41 and a second engagement receiving portion 42 on an inner side surface 40 a facing each other in the in-plane direction. They are provided opposite to each other in the in-plane direction.
A first interval L1 in the in-plane direction between the opposed first engagement receiving portions 41 and a second interval L2 in the in-plane direction between the opposed second engagement receiving portions 42 are the second interval L2. Is larger than the first interval L1.
In the illustrated pair of engagement receiving pieces 40, 40, the interval between the distal end portions 40b is larger than the interval between the proximal end portions 40c, and the second engagement receiving portion 42 is integrally provided at the distal end portion 40b. A first engagement receiving portion 41 is integrally provided near the distal end portion 40b of the proximal end portion 40c.

As shown in FIGS. 3 to 6, the pair of engagement pieces 51 of the cover member 8 are engaged with the outer side surface 51 b opposite to the inner side surface 51 a opposite to the inner side surface 51 a in the in-plane direction. 52.
In the case of the cover member 8 of the long engagement piece 51 shown in FIGS. 3 and 4, the third distance L3 in the in-plane direction between the engagement portions 52 of the pair of engagement pieces 51 is as shown in FIGS. 5 and 6. In the case of the cover member 8 of the short engagement piece 51 shown in FIG. 5, the distance is smaller than the fourth distance L4 in the in-plane direction between the engagement portions 52 of the pair of engagement pieces 51 and between the second engagement receiving portions 42. It is smaller than the second distance L2 in the in-plane direction.
In the case of the long engagement piece 51, the engagement portion 52 engages with the first engagement reception portion 41 beyond the second engagement reception portion 42 as shown in FIGS. The engaging portion 52 does not interfere with the second engaging receiving portion 42 when the combined piece 51 is pushed between the pair of engaging receiving pieces 40.

  Thus, when the cover material 8 having the long engagement piece 51 is attached, it is erroneously assumed that the cover material 8 can be attached by engaging the engagement portion 52 with the second engagement receiving portion 42. Since it can be correctly determined that the cover member 8 has been attached because the engaging portion 52 is engaged with the first engagement receiving portion 41 without being determined, the cover member 8 having the long engagement piece 51 is correctly attached. it can.

  As shown in FIGS. 5 and 6, in the case of the cover member 8 having the short engagement piece 51, the fourth interval L4 in the in-plane direction between the engagement portions 52 of the pair of engagement pieces 51 is The engagement portion 52 is engaged with the second engagement receiving portion 42 of the pair of engagement receiving pieces 40, which is larger than the second distance L <b> 2 in the in-plane direction between the second engagement receiving portions 42.

A cover portion 55 that is continuous with the outer side in the in-plane direction of the engagement piece mounting portion 53 is provided, and an airtight material 56 is attached to the cover portion 55 toward the outdoor side.
The hermetic material 56 includes an attachment portion 56 a and a fin portion 56 b provided on the attachment portion 56 a, and the attachment portion 56 a is fitted into the concave groove 55 a of the cover portion 55.

When the cover member 8 is attached, the front end surface of the cover portion 54 comes into contact with the indoor side portions 30a and 32a (inner side surfaces) of the new upper frame 30 and the new vertical frame 32, and the engagement receiving piece 40 and the engagement piece 51 Is not visible from the indoor side to improve the appearance of the interior.
Further, the fins 56b of the airtight material 56 are in contact with the indoor side portions 20a and 22a (inner side surfaces) of the existing upper frame 20 and the existing vertical frame 22, thereby closing the gap.

As shown in FIGS. 5 and 6, the cover member 50 having the short engagement piece 51 has a concave portion 57 at the distal end portion of the cover portion 54, and the concave portion 57 opens toward the outdoor side. .
And when the cover material 8 is attached, the recessed part 57 of the cover part 54 fits into the said protrusion 43, and it has controlled so that the front-end | tip part of the cover part 54 may not move to the inner side of an in-plane direction.
As such, the cover portion 54 of the resin cover material 8 prevents bending deformation, that is, warpage inward in the in-plane direction, and the indoor side portion of the cover portion 54, the new upper frame 30, and the new vertical frame 32. The inner end faces in the in-plane direction of 30a and 32a can be kept flush.

As shown in FIGS. 3 to 6, each airtight member 56 has a mounting portion 56 a made of a hard or semi-rigid synthetic resin material and a fin portion 56 b made of a soft synthetic resin material. That is, the fin portion 56b may be a soft material.
Accordingly, the fin portion 56b is easily elastically deformed with respect to the attachment portion 56a.
Thus, when a load toward the outdoor side is applied to the cover member 8 in a state where the fin portion 56b of the airtight member 56 is in contact with the indoor side portions 20a and 22a of the existing upper frame 20 and the existing vertical frame 22. In addition, each of the fin portions 56b is elastically deformed indoors smoothly with respect to the mounting portion 56a, so that the cover member 8 is moved to the outdoor side by the aforementioned load.
Therefore, when the negative wind acts on the new sash by the strong wind and is pulled to the outdoor side, the cover member 8 moves to the outdoor side together with the new upper frame 30 and the new vertical frame 32. The cover material 8 does not come off the new upper frame 30 and the new vertical frame 32 without coming off from the portions 41 and 42.
