An airtight material s is arranged on the outdoor end surface of the thick outer peripheral portion 212c of the resin mating stile 212, and is in contact with the indoor side surface of the mating stile 31 of the outer sash 3 described later.

In this way, the entire indoor side surface of the hollow portion of the metal convection stile 211 is covered with the indoor side hollow portion 212a formed by laminating a plurality of hollow portions having a larger found width than the indoor side surface in the prospective direction. The convection of air that transfers heat from the indoor side surface of the metal combination stile 211 is divided in the prospective direction, suppressing the heat transfer due to the air convection, and the entire outer peripheral surface of the metal combination stile 211. The outer peripheral portion of the hollow portion on the indoor side is covered with the thick outer peripheral portion 212c formed by extending the outer peripheral portion to the outdoor side, and the hollow portion is formed in cooperation with the outer peripheral surface of the metal convection stile. By doing so, it is possible to further prevent heat transfer from the surface of the metal combination stile 211 facing the room, and it is possible to further improve the heat insulating property of the combination stile 21.

As shown in FIG. 6, the door end (lower) stile 22 of the shoji 2 is composed of a metal door tip stile 221 and a resin door tip stile 222 that covers the indoor side surface of the metal door tip stile 221.
The metal door tip stile 221 is hollow with a hollow portion 221a arranged on the outer periphery of the outdoor side of a panel such as glass, and a glass frontage portion 221b extending in the inner peripheral direction from the outdoor end of the hollow portion 221a to form a glass frontage. It is composed of a groove-shaped rotary shaft mounting groove 221c provided on the outer periphery of the portion 221a.

The resin door tip stile 222 is adjacent to the indoor side of the first hollow portion 222a and the first hollow portion 222a that cover the entire indoor side surface of the hollow portion 221a of the metal door tip stile 221 and the rotary shaft mounting groove 221c, and is at least first. A second hollow portion 222b that covers the indoor upper portion of the hollow portion 222a, and a third hollow portion 222c that covers at least the indoor upper portion of the second hollow portion 222b adjacent to the indoor side of the second hollow portion 222b. It is composed of an indoor side hollow portion having a hollow portion laminated structure and a glass frontage hollow portion 222d extending in the inner peripheral direction at the indoor end of the third hollow portion 222c of the indoor side hollow portion to form a glass frontage. There is.
That is, the found dimensions of the plurality of hollow portions arranged on the indoor side of the metal door tip stile 221 are formed smaller as they are arranged on the indoor side, and the lower surfaces of the second hollow portion 222b and the third hollow portion 222c are formed. Is formed on a continuous inclined surface extending from the indoor side surface of the first hollow portion 222a.
Then, the indoor side surface of the metal door tip stile 221 and the outdoor side surface of the first hollow portion 222a are connected at a substantially central position in the prospective direction of the glass frontage of the internal shoji 2.
In this way, by forming the hollow portion on the indoor side of the resin door tip stile 222 that covers the indoor side surface of the metal door tip stile 221 into a hollow portion laminated structure, convection of air that transfers heat from the indoor side surface of the metal door tip stile 221. Is divided in the prospective direction, heat transfer due to air convection can be suppressed, and the heat insulating property of the door end stile 22 can be improved.
Further, by making the first hollow portion 222a adjacent to the metal door tip stile 221 a size that covers the entire interior side surface of the metal door tip stile 221, it is wide with respect to the heat directly transmitted from the interior side surface of the metal door tip stile 221. Insulation by an air layer can be performed in the range, and the insulation performance can be further improved.
The position of the partition wall that divides the first hollow portion 222a to the third hollow portion 222c of the resin door tip stile 222 is the position of the partition wall that divides the plurality of hollow portions in the indoor side hollow portion 212a of the resin combination stile 212. It is almost the same as the position in the expected direction.

In the closed state of the inner sash 2, the first hollow portion 222a of the resin door tip stile 222 of the inner sash 2 has its indoor side surface facing the outdoor side surface of the resin lower frame 122 of the lower frame 12, and the second hollow portion 222b and Since the third hollow portion 222c is arranged so as to face the upper surface of the angle portion 122a of the resin lower frame 122, the upper surface opening of the lower frame 12 in which the door tip stile 22 is housed when the internal sash 2 is closed is a metal door stile. It suffices to have a width sufficient to accommodate the first hollow portion 222a of the resin door tip stile 222 and the resin door tip stile 222, and the lower frame 12 is exposed in the room of the metal door tip stile 221 without increasing the dimension in the prospective direction. The transfer of heat from the surface can be efficiently prevented by the plurality of hollow portions.

Further, the groove portion whose opening becomes larger toward the room due to the upper surface of the angle portion 122a of the resin lower frame 122 and the continuous inclined surfaces of the second hollow portion 222b and the third hollow portion 222c facing the upper surface of the angle portion 122a. M is formed, the vertical dimension L of the indoor end of the groove M is set to 10 mm or less, and the depth dimension D of the groove M is set to be larger than the vertical dimension L.
As a result, convection of air in the groove M can be suppressed, and the groove M forms an air layer in a semi-sealed state, so that the heat insulating performance can be further improved.

An upright protrusion 122b extending in the left-right direction is formed on the indoor side of the upper left sub-resin vertical frame 133 on the upper surface of the angle portion 122a of the resin lower frame 122, and the vertical dimension L of the opening of the groove portion M is further reduced. Therefore, the convection of air in the groove M is further suppressed.
Since the upright protrusion 122b exists on the indoor side of the left secondary resin vertical frame 133, even if a gap is generated between the lower end of the left secondary resin vertical frame 133 and the upper surface of the resin lower frame 122, the gap Can be hidden from the room.

As described above, the door tip stile 22 of the internal shoji 2 has a larger found size than the first hollow portion 222a on the indoor side of the first hollow portion 222a that covers the entire indoor side surface of the hollow portion 221a of the metal door stile 221. Vertical dimension) The small second hollow portion 222b and the third hollow portion 222c are laminated to form the lower surface of the second hollow portion 222b and the third hollow portion 222c in an inclined shape that becomes higher toward the room. A plurality of hollow portions are laminated in a prospective direction to cover the entire indoor side surface of the hollow portion 221a of the metal door stile 221 to form an indoor hollow portion, and the found dimensions of the plurality of hollow portions are arranged on the indoor side. By closing the sash 2, a groove M that becomes a semi-sealed air layer is formed between the door stile 22 and the lower frame 12 of the sash 2, so that the door stile is formed. The heat insulating performance can be improved without processing the 22.

Further, since the lower surface of the door end stile 22 on the indoor side is formed in an inclined shape, dew condensation water or the like generated on the indoor side is guided to the lower frame 12 along the inclined lower surface, so that the frame or the like on the indoor side is formed. You can prevent it from getting wet.
The lower surfaces of the second hollow portion 222b and the third hollow portion 222c are not limited to those that are linearly inclined, and may be inclined in an arc shape.

Since the left and right vertical stiles 23 and 24 of the internal sash 2 have substantially the same configuration, the left and right vertical stiles 23 and 24 of the internal sash 2 will be described using the left vertical stile 23.
As shown in FIG. 4, the left vertical stile 23 includes a left metal vertical stile 231 and a left resin vertical stile 232 arranged on the indoor side of the left metal vertical stile 231.
The left metal vertical frame 231 is composed of a hollow portion 231a arranged on the outer outer periphery of the panel and a glass frontage portion 231b extending on the inner circumference of the outdoor side of the hollow portion 231a to form a glass frontage, and the hollow portion 231a. A link 83 connected to a slider 82 that slides the guide portion 132d of the left vertical frame 13 is rotatably connected to the outer peripheral surface of the left vertical frame 13 (FIG. 3), and mohair is connected to the outdoor surface of the hollow portion 231a. The airtight material m1 such as the above is arranged along the length direction over substantially the entire length.

The left resin vertical stile 232 is connected to the indoor side surface of the left metal vertical stile 231 at a substantially central position in the prospective direction of the glass frontage, and covers the entire indoor side surface of the left metal vertical stile 231. A state in which the second hollow portion 232b adjacent to the first hollow portion 232a and a state in which the finding direction dimension is larger than the second hollow portion 232b and protrudes in the outer peripheral direction are larger than those in the second hollow portion 232a. A hollow portion on the indoor side of a hollow laminated structure including a third hollow portion 232c adjacent to the second hollow portion 232b, and an inner peripheral end extending from the indoor end of the third hollow portion 232c in the inner peripheral direction. It is composed of a glass frontage portion 232d that is folded back to form a glass frontage, and the indoor side surface of the left metal vertical frame 231 and the outdoor side surface of the first hollow portion 232a are connected at a substantially central position in the prospective direction of the glass frontage of the inner shoji 2. Has been done.
In this way, by forming the indoor hollow portion of the left (right) resin vertical stile 232 covering the indoor side surface of the left (right) metal vertical stile 231 into a hollow portion laminated structure, the left metal vertical stile 231 can be viewed from the indoor side surface. The convection of the air that transfers heat is divided in the prospective direction, and the heat transfer due to the convection of the air can be suppressed, and the heat insulating property in the left (right) vertical stile 23 can be improved.
The position of the partition wall that divides the first hollow portion 232a to the third hollow portion 232c of the left (right) resin vertical stile 232 is the expected direction of the partition wall that divides the indoor side hollow portion 212a of the resin convection stile 212. By roughly matching the position and the position in the prospective direction of the partition wall that divides the first hollow portion 222a to the third hollow portion 222c of the resin door tip stile 222, the convection is divided through the entire stile of the inner sash 2. The positions can be substantially matched.
That is, the vertical and horizontal resin stiles constituting the shoji each have an indoor hollow portion that covers the indoor side surface of the hollow portion of the metal stile and is formed by laminating a plurality of hollow portions in a prospective direction divided by a partition wall. Since the positions of the partition walls that divide the indoor hollow portions of the vertical and horizontal resin stiles into a plurality of hollow portions in the prospective direction are substantially the same, the convection division positions that transfer heat in the entire stile of the shoji sash 2 are substantially the same. And further, the heat insulating property can be improved.

The outer peripheral surface of the second hollow portion 232b is close to the inner peripheral surface of the left secondary resin vertical frame 133 of the left vertical frame 13, and is in contact with the inner peripheral surface of the left secondary resin vertical frame 133 to make airtight between them. The airtight material m2 such as is arranged.
Further, the outer peripheral end of the third hollow portion 232c extends in the outer peripheral direction further from the inner peripheral end of the left sub-resin vertical frame 133 on the indoor side of the left sub-resin vertical frame 133 of the left vertical frame 13. By arranging a hollow portion made of resin on the indoor side between the left vertical frame 13 and the left vertical frame 23 so as to overlap the left secondary resin vertical frame 133 in the indoor and outdoor directions, the heat insulating performance is improved and the indoor space is improved. The design is improved by making it impossible to see directly between the window frame and the shoji.
Then, the closed space layer is formed by setting the distance d in the prospective direction between the indoor side surface of the left subresin vertical frame 133 of the left vertical frame 13 and the outdoor side surface of the third hollow portion 232c as shown in FIG. 4 to be 2 mm or less. can do.
Further, since the found dimensions of the first hollow portion 222a, the second hollow portion 222b, and the third hollow portion 222c that are laminated in the prospective direction are formed larger as they are arranged on the indoor side, it is like a sliding window. In windows where it is necessary to store a link mechanism or the like between the vertical frame and the vertical frame, prevent heat transfer from the space to the room while securing a relatively large space on the outer periphery of the first hollow portion 222a. Can be done.
As described above, the resin vertical stile constituting the vertical stile has an indoor hollow portion formed by laminating a plurality of hollow portions in a prospective direction, covering the entire indoor side surface of the hollow portion of the metal stile, and the plurality of hollow portions. Since the found dimensions of the above are formed larger as they are arranged on the indoor side, in the space between the vertical frame and the vertical stile, which requires a relatively large space, the space can be changed from the space to the room. It is possible to prevent heat transfer to.

As described above, in the heat insulating sash of the present embodiment, each stile of the inner sash 2 is composed of a metal stile and a resin stile having a hollow portion on the indoor side of a hollow portion laminated structure having a plurality of hollow portions in a prospective direction. Since any one of the hollow portions of the plurality of hollow portions of the resin stile is larger than the expected size of the indoor side surface of the metal stile and covers the entire indoor side surface of the metal stile, the entire indoor surface of the metal stile is covered. A heat insulating layer made of an air layer can be formed, and since the hollow portions are laminated, the convection of air due to the transferred heat can be separated, and the heat insulating property can be improved.
Further, by making the hollow portion adjacent to the metal stile a hollow portion that is larger than the expected size of the indoor side surface of the metal stile and covers the entire indoor side surface of the metal stile, the heat transferred directly from the indoor side surface of the metal stile is dealt with. By insulating with an air layer in a wide range, it is possible to efficiently insulate.

By using the inner side wall of the glass frontage, heat transfer from the glass frontage is prevented, and the heat insulating performance is further improved.
The interior wall of the glass frontage formed on the left resin vertical stile 232 and the right resin vertical stile 242 is formed by folding back the inner peripheral end of the interior wall without providing a hollow portion.
That is, the vertical and horizontal resin stiles constituting the shoji each have an indoor side hollow portion formed by laminating a plurality of hollow portions in the prospective direction, covering the indoor side surface of the hollow portion of the metal stile, and the chamber of the horizontal resin stile. It has a glass frontage hollow part independent of the indoor side hollow part extending in the inner peripheral direction from the indoor end inner peripheral surface of the inner hollow part, and from the indoor end inner peripheral surface of the indoor side hollow part of the vertical resin stile. Since it is extended in the inner peripheral direction and has a glass frontage portion with a folded tip, when the combination stile 21 and the door end stile 22 are assembled with respect to the left and right vertical stiles 23 and 24. By cutting off the folded portion of the interior wall of the glass frontage, it is possible to assemble the hozo, and the workability is good without deteriorating the heat insulating performance of the combination stile 21 and the door end stile 22.

Further, by arranging the connecting portion between each metal stile and the resin stile of the internal sash at a position substantially at the center of the glass frontage in the prospective direction, that is, the resin stile is expected to cover the entire interior side surface of the hollow portion of the metal stile. Since it has an indoor hollow part in which a plurality of hollow parts are laminated in the direction, and the prospective joint position between the metal stile and the resin stile is approximately the center position of the glass frontage, the heat insulating line of each stile is multi-layered. It can be substantially matched with the central position of the air layer, which is the heat insulating line of glass, and the heat insulating property can be improved.

In the present embodiment, the hollow portions constituting the resin frame of the internal shoji are laminated only in the prospective direction, and a plurality of hollow portions are not arranged in the finding direction. The resin sash of the internal shoji may be a hollow portion in which at least one of the hollow portions is equal to or larger than the found size of the indoor side surface of the metal stile and covers the entire indoor side surface of the metal stile. The finding size is not limited at all, and a plurality of layers may be stacked in the finding direction.
