Description

  The present invention relates to a sash window in which a heat insulating shape member in which a heat insulating bridge material is disposed between an outdoor member and an indoor member is used as a shoji cover.

There is known a heat insulating sash in which an outdoor member (shape member) made of an aluminum alloy and an indoor member (shape member) are connected by a heat insulating material made of a resin material or the like to form a shoji screen (for example, , See Patent Document 1).
Under the present circumstances, the said heat insulating material was arrange | positioned over the full length of an outdoor member and an indoor member, and was connected by caulking the outdoor member and the indoor member over the full length.

JP-A-7-305556

  In such a heat insulating shape, a temperature difference occurs between the outdoor member and the indoor member. Moreover, since the heat insulating material and the indoor / outdoor member are made of different materials and have different heat elongation amounts, the heat expansion amounts of the heat insulating material and the indoor / outdoor members are also different. For this reason, if the temperature changes greatly due to direct sunlight or the like, thermal warpage occurs due to the difference in the amount of thermal expansion of each member. In particular, in the case of a large sash window with a height dimension of about 2 meters, such as a sash that forms a terrace window, the difference in the amount of thermal expansion of the ridge part is large in proportion to the height dimension of the ridge. For this reason, the amount of thermal warpage is also increased, and therefore it has been demanded to eliminate the thermal warpage.

  The objective of this invention is providing the sash window which can reduce the amount of thermal warp of a heat insulation shape material in the sash window using the heat insulation shape material.

  The present invention is a sash window comprising a window frame composed of an upper frame, a lower frame and left and right vertical frames, and a shoji composed of an upper frame, a lower frame and left and right frames, And at least one of the left and right saddles is a metal outdoor member and indoor member having a pocket portion, and is disposed across the outdoor member and indoor member and inserted into each pocket portion. The heat insulating bridge material includes a heat insulating bridge member, and the heat insulating bridge member is fixed to the pocket portion at one end in the longitudinal direction, and slides in the longitudinal direction with respect to the pocket portion except for the fixed end. A gap having a predetermined dimension is formed between the end face of the other end and the member facing the end face in the shoji.

  Here, the heat insulating bridge material may be a member made of at least a metal outdoor member or a material (heat insulating material) having a lower thermal conductivity than the indoor member, such as a urethane resin or a vinyl chloride resin. Can be used that is made of a synthetic resin that has a low thermal conductivity and is difficult to pass heat.

In such a sash window, only one end side in the longitudinal direction of the heat insulating bridge material is fixed by caulking, adhesive, screws, etc., so other portions are against the outdoor member and the indoor member, that is, each pocket portion. Can slide freely.
For this reason, the other end portion of the outdoor member of the heat insulating shape member can also slide freely with respect to the heat insulating bridge material and the indoor member, and thermal warpage in the heat insulating shape member can be prevented. That is, in the case where a heat insulating bridge material is interposed between indoor and outdoor members made of aluminum alloy or the like, when the outdoor member is heated by direct sunlight, the heat is blocked by the heat insulating bridge material, and between the outdoor member and the indoor member. A temperature difference occurs, and a difference in thermal elongation occurs between the indoor and outdoor members. If the heat insulating bridge member is fixed by caulking or the like over the entire length of the indoor / outdoor member as in the prior art, thermal warping occurs in the heat insulating shape due to the difference in thermal elongation.
On the other hand, in the present invention, the other end portion of the heat insulating bridge member can freely slide with respect to the indoor / outdoor member, so that the other end portion of the outdoor member can also freely slide with respect to the heat insulating bridge member and the indoor member. Even if a difference in the amount of thermal expansion occurs between the indoor and outdoor members, the end of the outdoor member moves freely with respect to the end of the indoor member, and the occurrence of thermal warpage can be prevented.
In addition, since the other end portion of the heat insulating bridge material can be freely slid relative to the indoor / outdoor member, when the heat insulating bridge material is thermally expanded, the heat insulating bridge material such as other scissors and sliding pieces of the shoji There arises a new problem that does not occur when the entire length of the heat insulating bridge material is fixed by caulking or the like. When the heat insulating bridge material collides with the sliding piece etc., the problem that the sliding piece etc. is pushed up, or the heat insulating bridge material is bent and the sliding movement of the other end of the heat insulating bridge material is obstructed, contributing to thermal warping. The problem of becoming may occur.
On the other hand, in the present invention, a gap of a predetermined dimension is formed on the other end side of the heat insulating bridge material, so that when the heat insulating bridge material is thermally expanded, the heat insulating bridge material collides with the sliding piece or the like. Can be prevented. Therefore, the problem that the sliding piece is pushed up, and the problem that the heat insulating bridge material is curved and contributes to thermal warping can be prevented.

Moreover, since the one end part side of the heat insulation bridge | bridging material is being fixed to the outdoor member and the indoor member by caulking etc., an outdoor member and an indoor member can be connected with predetermined intensity | strength. For this reason, even if an impact such as dropping is applied, the outdoor member and the indoor member can be prevented from shifting.
In addition, for example, when the heat insulating bridge material is fixed by caulking or screws, the number thereof is adjusted, and when the heat insulating bridge material is fixed with an adhesive, the bonding area is adjusted. It is possible to easily adjust the connection strength required for the operation.
Furthermore, since the heat insulating bridge member is fixed only at one end portion, even when it is fixed by caulking or the like, the number of processing steps can be reduced compared to the case of caulking over the entire length, and the processing operation can be easily performed.

  Moreover, since the one end part of the heat insulation bridge material is being fixed to the pocket part, the direction in which heat insulation (thermal expansion) is carried out in the heat insulation bridge material can be controlled only to the other end part side. For example, if only the middle part of the heat insulation bridge material is fixed, the heat insulation bridge material will be thermally stretched at the both right and left ends with respect to the fixed middle part, and the design considering the heat elongation at each end part. There is a need to do. On the other hand, in this invention, since a heat | fever elongation direction can be controlled to one direction, a clearance gap should just be formed only in the other end part side of a heat insulation bridge | bridging material, and a shoji can be designed easily.

  In the present invention, all the upper and lower folds of the shoji may be made of the heat insulating shape, and only the heel that is likely to cause thermal warpage is made of the heat insulating shape. Also good. For example, a hook guided by a rail, such as the upper and lower hooks of a sliding window, can prevent thermal warping by the rail, so that thermal warpage is less likely to occur than a hook not guided by the rail. In such a case, only the wrinkles that are likely to be warped are formed of the heat insulating shape material, and the upper wrinkles and the lower wrinkles are fixed by caulking or the like over the entire length in the longitudinal direction as in the conventional case. You may comprise with the heat-insulated shape material.

  Here, the shoji fold is composed of the heat insulating shape material, and the heat insulating bridge material is fixed to the pocket portion only at the lower end portion, and slides in the longitudinal direction with respect to the pocket portion except for the fixed lower end portion. It is preferable that a gap having a predetermined dimension is formed between the end face of the upper end portion and a member facing the end face in the shoji.

  In the heat insulating bridge material in the heel, if the lower end portion is fixed by caulking or the like and a gap is formed at the upper end portion, the user can be compared with a case where the upper end portion is fixed by caulking and a gap is formed on the lower end portion side. Since a gap is formed at a location that is difficult to visually recognize, the design can be further improved.

Further, in the heat insulating shape member, an end member is attached to an end portion on the other end side of the heat insulating bridge member, and the gap is formed between the end member and the other end surface of the heat insulating bridge member. In addition, the end member preferably includes a covering piece that covers the gap so that it cannot be visually recognized from the outside.
Here, as the end member, for example, an upper sliding piece that guides the rail can be used in the sliding window fold of the sliding window, and an end portion that closes the opening of the ridge in the case of the opening window or the like. Caps can be used.
If the covering piece is formed on the end member, the gap between the heat insulating bridge member and the end member can be closed, so that the design can be prevented from deteriorating. In addition, what is necessary is just to arrange | position a covering piece to the outer peripheral side of a clearance gap, for example, as long as it can coat | cover the clearance gap so that a user cannot visually recognize the clearance gap.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show a cross section of the sash window 1, but in order to make the drawings easy to see, the cross sections of the main constituent members are omitted.

  Each of the upper frame 11, the lower frame 12, and the vertical frames 13 and 14 is attached to the housing by fixing the outdoor members 11 </ b> A to 14 </ b> A and the indoor members 11 </ b> B to 14 </ b> B to the housing side with screws or the like.

The outer shoji 20A and the inner shoji 20B have upper and lower ridges 21 and 22, lower ridges 23 and 24, left and right ridges 25 and 26, and an outer summit tub 27 and an inner summit skirt 28, respectively. It is composed of
A multi-layer glass 29 that is a face material is fitted to the inner peripheral surface of each of the flanges 21 to 28 via a gasket 30.

Each of the flanges 21 to 26 is an aluminum alloy outdoor member 21A to 26A, an aluminum alloy indoor member 21B to 26B, and a heat insulating bridge member 21C that connects the outdoor members 21A to 26A and the indoor members 21B to 26B. ~ 26C.
Among these, since each of the lower rods 23 and 24 has a large height dimension, three heat insulating bridge members 23C and two heat insulating bridge members 24C are provided, respectively.

Further, the outer summoning bowl 27 of the outer shoji 20A is provided with the inner summoning bowl 28 on the indoor side and does not require heat insulation performance. It is composed of goods.
On the other hand, the inner summon bowl 28 of the inner shoji 20B includes an aluminum alloy outdoor member 28A exposed to the outdoor side when the shoji is closed, and an aluminum alloy disposed on the indoor side of the outer shoji 20A and exposed to the indoor side. It is comprised by the indoor member 28B made from, and the heat insulation bridge | bridging material 28C which connects these.

Then, upper and lower rods 21, 22 and lower rods 23, 24 are arranged between the left and right rods 25, 26, the outer summoning rod 27, and the inner summoning rod 28, and screws the indoor members 21B to 26B, 28B to each other. By stopping, the external obstacle 20A and the internal obstacle 20B are assembled in a square frame shape. For this reason, the outdoor members 25A and 26A of the flanges 25 and 26 are caulked and fixed only to the heat insulating bridge members 25C and 26C, that is, the indoor members 25B and 26B, and the other members can be slid freely with respect to each other. Yes. Further, since the outdoor members 25A and 26A are not engaged with the upper collars 21 and 22, also in this respect, they can be slid freely.
Further, as shown in FIG. 3, an upper side sliding piece 50 which is an end member sandwiching the upper rails 16 and 17 is attached to the upper end of each bowl (summit bowl) 25-28, and the lower end is attached to the lower end. Is attached with a lower sliding piece 60 which is an end member sandwiching the lower rails 18 and 19.

[Insulating bridge material and sliding piece mounting structure]
Next, the mounting structure of the heat insulating bridge members 21C to 26C, 28C, the upper side sliding piece 50, and the lower side sliding piece 60 will be described in detail using the flange 25 as an example.
In the outdoor members 21A to 26A and 28A and the indoor members 21B to 26B and 28B, pocket portions 40 having a substantially C-shaped cross section are integrally formed so as to face each other in the same manner as the pocket portion 15 of the window frame 10. Yes.
As shown in FIG. 4, each of the pocket portions 40 formed to face each other includes two projecting piece portions 41 projecting in directions facing each other, and an engaging piece projecting in an orthogonal direction from the projecting piece portion 41. And is formed integrally with each of the outdoor members 21A to 26A, 28A and the indoor members 21B to 26B, 28B by extrusion molding. Accordingly, the engagement groove 43 in which the heat insulating bridge members 21C to 26C and 28C are engaged by the pocket portion 40 is formed over the entire length in the longitudinal direction of each of the outdoor members 21A to 26A and 28A and the indoor members 21B to 26B and 28B. ing. 4 and 6, the heat insulating bridge members 21C and 25C are hatched so as to be easily distinguished from the outdoor members 21A and 25A and the indoor members 21B and 25B.

  The heat insulating bridge members 21 </ b> C to 26 </ b> C and 28 </ b> C are slid and inserted into the engagement grooves 43 of the pocket portions 40 from the opening end surfaces of the pocket portions 40. Each of the heat insulating bridge members 21C to 26C, 28C is the same as the heat insulating bridge members 11C to 14C, and is made of a hard synthetic resin such as urethane resin, vinyl chloride resin, polyamide, phenol, or the like, which has been molded in advance, or these resins are made of glass. It is made of a reinforced resin reinforced with fiber, carbon fiber or the like. The heat insulating bridge members 21C to 26C and 28C also have a substantially I-shaped cross section, that is, a shape in which flange portions are formed at both ends of a substantially plate shape, and the flange portions are engagement grooves of the pocket portion 40. 43 is engaged. Since this flange portion is locked to the engagement piece portion 42, the outdoor members 21A to 26A and 28A and the indoor members 21B to 26B and 28B can be obtained only by inserting the heat insulating bridge members 21C to 26C and 28C into the pocket portion 40. Are connected by the heat insulating bridge members 21C to 26C and 28C so that the distance between them is not widened.

Further, the engaging portions of the upper side sliding piece 50 and the lower side sliding piece 60 are engaged with the pocket portions 40 of the collars 25 and 26 and the inner summoning collar 28.
The upper side sliding piece 50 attached to the flange 25 will be described as an example. As shown in FIGS. 3, 5, and 6, the upper side sliding piece 50 is disposed across the outdoor member 25A and the indoor member 25B. The That is, the upper side sliding piece 50 is connected to the outdoor side wall portion 51 engaged with the outdoor member 25A side, the indoor side wall portion 52 engaged with the indoor member 25B side, and the wall portions 51 and 52. A sliding groove 54 through which the upper rail 16 is inserted is formed between the wall portions 51 and 52. The wall portions 51 and 52 are integrally formed with cover portions 51A and 52A that cover the upper end surfaces of the outdoor member 25A and the indoor member 25B.

And each wall part 51 and 52 of the upper side sliding piece 50 is provided with the engaging parts 55 and 56 engaged with the engaging groove 43 of the outdoor member 25A of the collar 25, and each pocket part 40 of the indoor member 25B. ing.
As shown in FIGS. 7 and 8, the engaging portions 55 and 56 include an insertion guide portion 55 </ b> A having a smaller width than the engaging groove 43, a width expanding portion 55 </ b> B having an increased width, and a width dimension. Is provided with a fitting portion 55 </ b> C substantially the same as the width dimension of the engaging groove 43. For this reason, when the engaging portions 55 and 56 are initially inserted into the pocket portion 40, the insertion guide portion 55A is inserted into the engaging groove 43, so that the central axes of the engaging groove 43 and the engaging portions 55 and 56 are somewhat different. Even if it is displaced, it can be inserted smoothly. When the upper side sliding piece 50 is further pushed in, axial alignment is performed by the width expanding portion 55 </ b> B, and then the fitting portion 55 </ b> C is press-fitted into the engagement groove 43.
Accordingly, the upper sliding piece 50 engages with each pocket portion 40 to connect each outdoor member 25A and the indoor member 25B, similarly to the heat insulating bridge member 25C.
Although not shown, in the upper side sliding piece 50 attached to the other basket 26 and the inner summoning bowl 28 and the lower side sliding piece 60 attached to each of the collars 25 and 26 and the inner summing bowl 28, In addition, an engagement portion that engages with each pocket portion 40 is formed, and by engaging this engagement portion with the engagement groove 43, each of the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B are connected. is doing.

It should be noted that the engaging portions 55 and 56 of the upper side sliding piece 50 and the lower side sliding piece 60 may be merely press-fitted into the pocket portion 40, or more firmly by caulking the pocket portion 40 after press-fitting. It may be fixed.
Moreover, after each thermal insulation bridge | bridging material 21C-26C, 28C is inserted in the pocket part 40, it fixes only the one end part side of the longitudinal direction of the thermal insulation bridge | bridging materials 21C-26C, 28C by caulking.

  In other words, in the present embodiment, the heat insulating bridge members 25C, 26C, and 28C attached to the respective scissors 25 and 26 and the inner summon scissors 28 are arranged adjacent to the lower end side, that is, the upper side of the lower sliding piece 60. Only the part to be fixed is fixed by caulking. For example, even if the height of the shoji 20A, 20B is as high as about 2 meters and the height (longitudinal) size of each heat insulating bridge member 25C, 26C, 28C is also close to 2 meters like a terrace window, Caulking is performed only at the lower end within a height range of about 10 centimeters from the lower end edge.

  This caulking area is set by the number of caulking. That is, since each caulking location is performed at intervals of about 1 cm, for example, if 10 caulking is performed, the area where caulking is performed is about 10 cm. Further, since the connection strength increases as the number of caulking increases, the number of caulking is set according to the required connection strength. The caulking of the heat insulating bridge members 25C, 26C, and 28C is mainly due to an impact when the shojis 20A and 20B are accidentally dropped during transportation, and the outdoor members 25A, 26A, and 28A and the indoor members 25B, 26B, and 28B are What is necessary is just to prevent shifting in the longitudinal direction. Therefore, the number of crimps may be set according to the required strength.

  Moreover, as for the heat insulation bridge | bridging materials 21C-24C attached to the upper cage | baskets 21 and 22 and the lower cage | baskets 23 and 24, only the edge part by the side of the outer summoning basket 27 and the inner summoning basket 28 is fixed by crimping. ing. This caulking number may be set according to the required strength.

The heat insulating bridge members 21C to 26C and 28C made of synthetic resin have a larger amount of expansion and contraction due to temperature change than the outdoor members 21A to 26A and 28A and the indoor members 21B to 26B and 28B made of aluminum alloy. For this reason, when the temperature of the heat insulating bridge members 21C to 26C, 28C rises in summer or daytime, the upper end side of the heat insulating bridge members 25C, 26C, 28C that is not fixed by caulking extends upward, that is, toward the upper sliding piece 50 side. In addition, the end portions of the heat insulating bridge members 21C to 24C on the side of the flanges 25 and 26 are located on the side of the flanges 25 and 26, that is, on the upper side sliding piece 50 or the lower side sliding piece 60 attached to the side walls 25 and 26. Stretch.
For this reason, in the present embodiment, the upper-side sliding piece 50 and the lower-side sliding are previously provided so that the heat insulating bridge members 21C to 26C and 28C do not collide with the upper-side sliding piece 50 and the lower-side sliding piece 60 during extension. Gaps (clearances) 71 and 72 are provided between the piece 60.

Specifically, in the heat insulating bridge materials 21C to 24C, the end edges of the outer summing rods 27 and the inner summoning rods 28 of the respective ridges 21 to 24 are flush with the end edges of the respective ridges 21 to 24. The edge side is fixed by caulking. On the other hand, as shown in FIG. 4 (A), the edges of the heat insulating bridge members 21C to 24C on the side of the flanges 25 and 26 are not extended to the edges of the flanges 21 to 24, and are predetermined from the edges. It is provided only up to a position separated by the dimension L1. That is, the length dimension of the heat insulating bridge members 21C to 24C is shortened by the dimension L1 as compared with the outdoor members 21A to 24A and the indoor members 21B to 24B of the respective cages 21 to 24 in the state of the reference temperature, and the heat insulating bridge member 21C. A gap 71 is provided between ˜24C and the upper side sliding piece 50 and the lower side sliding piece 60.
For this reason, as shown in FIG. 4B, even if the temperature rises and the heat insulating bridge members 21C to 24C expand, the gap 71 of the dimension L2 remains on the sliding pieces 50 and 60, and the sliding It is comprised so that it may not collide with piece 50,60.

Similarly, the heat insulating bridge members 25C, 26C, and 28C are adjacent to the upper end edge of the lower sliding piece 60 on the lower end side, and the end edge side is fixed by caulking. On the other hand, the upper end sides of the heat insulating bridge members 25C, 26C, and 28C are provided only up to a position away from the lower end edge of the upper sliding piece 50 by a predetermined dimension H1, as shown in FIG. That is, the height dimensions of the heat insulating bridge members 25C, 26C, and 28C are set to the height dimensions of the outdoor members 25A, 26A, and 28A, and the indoor members 25B, 26B, and 28B of each of the scissors 25, 26, and 28 in the state of the reference temperature. Compared with the height dimension of each sliding piece 50, 60 and the height dimension H1, it is shortened, and between the heat insulating bridge members 25C, 26C, 28C and the upper side sliding piece 50, A gap 72 is provided.
Therefore, as shown in FIG. 8B, even if the temperature rises and the heat insulating bridge members 25C, 26C, and 28C expand, a gap 72 having a height dimension H2 remains with respect to the upper sliding piece 50. The upper side sliding piece 50 is configured not to collide.
The predetermined dimensions L1 and H1 of the gaps 71 and 72 may be set as appropriate in the implementation. For example, the heat insulating bridge members 25C and 26C having a height dimension of 2 m and a linear expansion coefficient of 6 × 10 ⁻⁵ / ° C. are used. In the case of the scissors 25 and 26, when the temperature rises from 20 degrees to 50 degrees by 30 degrees, the heat insulating bridge members 25C and 26C thermally expand by 3.6 mm due to the temperature change. Accordingly, the dimension H1 of the gap 72 may be larger than the thermal elongation amount of the heat insulating bridge members 25C and 26C, for example, 5 mm. As described above, the predetermined dimension H1 of the gap 72 may be set according to the thermal elongation amount of the heat insulating bridge material, and is set to about 5 to 10 mm in a terrace door sash having a height dimension of about 2 to 2.5 m. do it.

In addition, since the part in which each heat insulation bridge | bridging material 21C-26C, 28C is provided is divided from the outdoor side by the sealing material contact | abutted to the rails 16-19 etc., even if a clearance gap is formed, watertightness or airtightness Does not affect sex. Moreover, since the user cannot visually recognize the upper and lower ridges 21 to 24 and the gaps 71 and 72 in the inner summon ridge 28, the design is not deteriorated.
However, since the gap 72 generated in the flanges 25 and 26 is exposed to the side surfaces when the shojis 20A and 20B are opened, the user can visually recognize them. For this reason, the upper-side sliding piece 50 is formed with a covering piece 57 that is disposed on the outer surface side of the heat insulating bridge members 25C and 26C and covers the gap 72 portion.

According to this embodiment, there are the following effects.
(1) Since the heat insulating bridge members 21C to 26C and 28C are fixed by caulking only at one end portion in the longitudinal direction, the outdoor members when the heat insulating bridge members 21C to 26C and 28C expand and contract depending on the temperature. The heat insulating bridge members 21C to 26C and 28C can be slid freely with respect to 21A to 26A and 28A and the indoor members 25B, 26B and 28B.
For this reason, the outdoor members 21A to 26A, 28A and the indoor members 25B, when the heat insulating bridge members 21C to 26C, 28C are injected and fixed in the pocket portion 40, or are caulked over the entire length, The heat insulating shape members (each ridge 21 to 26, 28) do not warp due to the difference in the amount of thermal elongation between 26B and 28B. In other words, in the present embodiment, the other end portions of the heat insulating bridge members 21C to 26C and 28C can freely slide, so the other end portions of the outdoor members 21A to 26A and 28A are the other end portions of the indoor members 25B, 26B and 28B. Can be freely slid with respect to each other, and warpage of each of the flanges 21 to 26, 28 can be prevented. In particular, thermal warpage can be effectively prevented even in the case of the large and long ridges 25, 26, and 28.

  (2) Since the predetermined gaps 71 and 72 are formed between the heat insulating bridge members 21C to 26C and 28C and the upper side sliding piece 50 and the lower side sliding piece 60, the heat insulating bridge material 21C. Even if .about.26C and 28C are thermally expanded, they can be prevented from colliding with the sliding pieces 50 and 60, and the upper side sliding piece 50 and the like can be prevented from being pushed up by the collision. Further, since it is possible to prevent the heat insulating bridge members 21C to 26C and 28C from being bent, the end portions of the outdoor members 21A to 26A and 28A and the indoor members 25B, 26B and 28B can be freely slid and moved. Generation of thermal warpage can be prevented.

  (3) Since the covering piece 57 is formed on the upper side sliding piece 50, the gap 72 between the heat insulating bridge members 25C, 26C and the upper side sliding piece 50 can be closed, and the design property is reduced. Can be prevented. Furthermore, since the heat insulation bridge members 25C and 26C have the lower end portion thereof fixed by caulking to form the gap 72 at the upper end portion, it is difficult for the user to visually recognize as compared with the case where the gap is formed on the lower end side. Since the gap 72 is formed at the location, the design can be further improved.

(4) The upper side sliding piece 50 and the lower side sliding piece 60 which are end members provided at the upper and lower ends of the shochus 25A and 26 of the shoji 20A and 20B and the inner summing hook 28 are respectively connected to the outdoor members 25A and 26A. , 28A and the indoor members 25B, 26B, 28B and engaged with the pocket portions 40, the connection strength between the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B can be improved. The bending / torsional rigidity of the collars 25 and 26 and the inner summon bowl 28 can be improved.
Moreover, since the upper side sliding piece 50 and the lower side sliding piece 60 are formed in a plane shape orthogonal to the longitudinal direction of the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B, the indoor member 25B. , 26B, 28B, when the outdoor members 25A, 26A, 28A are bent or twisted in the direction perpendicular to the axis, the upper side sliding pieces 50 and the lower side sliding pieces 60 can support the force. Therefore, the bending rigidity and torsional rigidity of each of the collars 25 and 26 and the inner summoning collar 28 can be effectively improved. In particular, the sliding pieces 50 and 60 have two engaging portions 55 and 56, respectively, and are engaged with the outdoor members 25A, 26A and 28A and the indoor members 25B, 26B and 28B at two locations, respectively. The bending rigidity and torsional rigidity of each flange 25, 26, 28 can be further improved.

  (5) The upper side sliding piece 50 and the lower side sliding piece 60 are provided in the pocket portion 40 in which the heat insulating bridge members 25C, 26C, and 28C are inserted in the outdoor members 25A, 26A, and 28A and the indoor members 25B, 26B, and 28B. Since the engaging portions 55 and 56 are engaged, it is not necessary to separately form a new pocket portion for engaging the sliding pieces 50 and 60. Therefore, the outdoor members 25A, 26A, and 28A and the indoor members 25B, 26B, and 28B can be the same as the conventional ones, and only the upper side sliding piece 50 and the lower side sliding piece 60 need be newly prepared. Therefore, the increase in cost can be minimized, and the rigidity of the heat insulating shape can be improved inexpensively and easily.

  (6) Since the upper side sliding piece 50 and the lower side sliding piece 60 need only be press-fitted into the pocket portion 40 and caulked as appropriate, the mounting work can be performed more easily than when fixed with screws or the like. be able to. Furthermore, since the engaging portions 55 and 56 of the sliding pieces 50 and 60 are constituted by the insertion guide portion 55A, the width expanding portion 55B and the fitting portion 55C having different width dimensions, the engaging portions 55 and 56 can be easily formed. It can be inserted into the pocket portion 40, and the mounting workability can also be improved in this respect.

  (7) In the present embodiment, the sliding pieces 50, 60 also serve as end members for connecting the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B. There is no need to do this, and it is only necessary to partially modify the structure of the sliding pieces 50 and 60 that have been used conventionally, so that an increase in the number of parts can be suppressed and an increase in cost can also be suppressed.

  (8) Since the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B are connected by the sliding pieces 50, 60, the heat insulating bridge members 25C, 26C, 28C do not need to be caulked over the entire length. Since only a part of the end portion needs to be caulked, the caulking work is reduced and the productivity can be improved.

In addition, this invention is not limited to the structure of each said embodiment.
For example, in the above-described embodiment, the heat insulating bridge members 21C to 26C and 28C are caulked at the lower end portion and the end portions on the summoning rods 27 and 28, but the upper end portion is caulked on the door toe rafts 25 and 26 side and fixed. May be.
Furthermore, you may fix the heat insulation bridge | bridging materials 21C-26C, 28C using other fixing means, such as an adhesive agent and a screw, without fixing by caulking.

  In the said embodiment, although the said heat insulation shape material in which the one end part of the heat insulation bridge | bridging materials 21C-26C, 28C was fixed to the ridges 21-26,28 of the shoji 20A, 20B was used, for example, 竪 框 25,26 Only the above-mentioned heat insulating shape material is used, and other ridges are formed by caulking the heat insulating bridge material over the entire length as in the past, or by forming a heat insulating bridge material by injecting molten resin into the pocket portion 40. It may be configured. In other words, in the shoji, the heel portion where heat warpage is likely to occur may be formed of the heat insulating shape. For example, in a normal sash window, the upper and lower ridges are shorter in size than the ridge, and in sliding windows, they are guided by rails and are unlikely to generate thermal warpage. Also good.

  Further, the heat insulating bridge members 11C to 14C of the window frame 10 may be caulked over the entire length, may be caulked only at a part of the end portion or the intermediate portion, or may be only inserted into the pocket portion 15 without being caulked. Alternatively, molten resin may be injected into the pocket portion 15 and configured. This is because the outdoor members 11A to 14A and the indoor members 11B to 14B of the window frame 10 are fixed to the housing with screws or the like, so that thermal warpage does not occur.

The end member of the present invention is not limited to those using the upper side sliding piece 50 and the lower side sliding piece 60. For example, in the case of an opening window that does not include a sliding piece, an end cap that is attached to a shoji screen may be used as the end member. Furthermore, even when the upper side sliding piece 50 and the lower side sliding piece 60 are provided, an end member may be provided separately from these sliding pieces 50 and 60.
Moreover, it is not necessary to connect an outdoor member and an indoor member with an edge part member, You may use the general sliding piece which does not have such a connection structure. Further, the end member may not be provided with a covering piece that closes the gap 72.

Moreover, the material of each heat insulation bridge | bridging material 21C-26C, 28C should just be selected suitably in implementation, as long as it can maintain heat insulation performance with low heat conductivity, such as a synthetic resin.
Furthermore, other configurations, for example, the specific structures / shapes of the face materials held by the flanges 21-28, the flanges 21-28, the structures of the frames 11-14, the mounting structure to the frame, etc. The present invention is not limited to the above embodiment.

  The present invention can be used for a heat-insulating sash window having a shoji having a ridge made of a heat-insulating shape material, and a sash window that can open a shoji such as a sliding window, a swing window, a raising / lowering window, a sliding window, and a shoji It can be used for FIX windows fixed to window frames and various sash windows such as entrance doors.
