It is formed by combining a synthetic resin portion 8b such as vinyl, and a pair glass 9 is mounted inside.

The metal part 8a has a basic structure of a frame, and is exposed outside the room. On the other hand, the synthetic resin portion 8b covers the inner peripheral surface of the metal portion 8a and is locked to the metal portion at two portions. The synthetic resin portion 8b has hollow protrusions 12 and 13 at the outer and inner edges of the frame, respectively, facing the outdoor protrusion 11 of the metal portion 8a. ing. Further, the outer edge of the combination frame of the sliding door 3 on the outdoor side is in a state where the metal portion 8a is exposed.

With the above-mentioned frame configuration, all the portions facing the room in the closed state (the state shown in FIG. 1) except for the glass 9 are made of the synthetic resin portion 8b. Further, since the outer edges of the combination frames of the sliding doors 2 and 3 on the outdoor side are formed of the metal portion 8a, the metal portion 8a is entirely exposed at the portion facing the outdoor.

The window frame 1 has an upper frame 14, a lower frame 15, and left and right vertical frames 16 in a rectangular frame. Each of the frame members is also made of a metal part made of aluminum or an alloy thereof and a polychlorinated metal. It is a composite sash made of synthetic resin such as vinyl.

The upper frame 14 is formed by integrally combining an upper metal part 14a and a lower synthetic resin part 14b.

4a abuts on the guide projection 21; the middle hollow projection 23 contacts the guide edge of the indoor sliding door 2; Respectively. Since the synthetic resin portion 14b is disposed over the entire lower surface of the metal portion 14a, the synthetic resin portion 14b also faces the outdoor with the sashes 2 and 3 closed. Also, the synthetic resin portion 14
b and the metal portion 14a are locked at a portion outside the room and a portion inside the room.

The upper frame 14 is fixed by screwing the mounting edge 18 of the metal portion 14a and the mounting edge 24 of the synthetic resin portion 14b on the indoor side to the upper member 17a.

The lower frame 15 is formed by integrally joining a synthetic resin portion 15b to a part of the upper surface of the metal portion 15a.
A mounting edge 25 attached to the outer surface of the lower member 17b of the window opening 17 of the building frame, an L-shaped mounting edge 26 attached to the upper surface, a hollow portion 27 protruding to the outside of the mounting edge 26, and a hollow portion. 27, a screen door rail 28 and two sliding door rails 29, 30 projecting upward from the outdoor end, the middle part, and the indoor end, respectively. On the other hand, the synthetic resin portion 15b is composed of a coupling resin portion 31 disposed on the entire length of the indoor sliding door rail 30 on the indoor side and a resin piece 32 disposed on the outdoor half of the sliding door rail 30. It is configured. The coupling resin portion 31 is integrally connected to the indoor resin portion 31a and the outdoor resin portion 31b each including a plurality of hollow portions, and the indoor resin portion 31a is attached so as to cover an upper portion of the L-shaped mounting edge 26, The outdoor resin portion 31b is mounted between the sliding door rail 30 on the indoor side and the L-shaped mounting edge 26 so as to float.

The lower frame 15 has two mounting edges 25, 26.
Are fixed to the outer surface and the upper surface of the lower member 17b of the window opening 17 by screws.

As shown in FIG. 4, the resin piece 32 has an engagement piece 34 erected from the upper end and the lower end of the hollow portion 33 on the indoor side, and the projecting piece 35 from the lower end on the outdoor side.
The outer portion of the indoor sliding door rail 30 of the synthetic resin portion on the upper surface of the lower frame 15 and facing the room with the sliding doors 2 and 3 closed as shown in FIG. Therefore, it is disposed only on the sliding portion of the indoor sliding door 2 when the sliding door 2 is opened, and as shown in FIG.
Block 3 made of synthetic resin attached to the upper center
7 is inserted into an insertion opening 38 formed on the side surface of the base 7, and is attached and fixed by engaging the engagement piece 34 with the metal portion 15 a.

The vertical frame 16 is formed by integrally joining a synthetic resin portion 16b to a portion facing the indoor side of the metal portion 16a. The metal portion 16a is formed on the outer surface of the side member 17c of the window opening 17 of the building frame. It comprises a mounting edge 40 to be mounted, a hollow portion 41 projecting to the outdoor side of the mounting edge 40, and a screen door guiding edge 42 protruding inward from the outdoor end of the hollow portion 41. On the other hand, the synthetic resin portion 16b is composed of a plurality of hollow portions, and is arranged from the door stop surface of the metal portion 16a to the indoor side. A concave portion 43 is formed at a portion corresponding to the door stop surface of each of the sliding doors 2 and 3. Also, the synthetic resin portion 16b
The metal part 16a and the metal part 16a are engaged with each other at the outdoor part and the indoor part.

The vertical frame 16 is attached to the mounting edge 40 by the window opening 1.
7 is screwed and fixed to the outer surface of the side member 17c.

According to the above construction, a sliding window is formed from the window frame 1 and the shojis 2 and 3 by a composite sash material formed by combining a metal portion and a synthetic resin portion. The lower surface of the upper frame 14 of the window frame 1 and the part facing the room, the upper surface of the lower frame 15 and the part facing the room with the shojis 2 and 3 closed, and the side surface of the vertical frame 16 on the indoor side. Synthetic resin portions 14b, 15b, and 16b are disposed at a portion facing the room and a portion facing the room with the shojis 2 and 3 closed, respectively. The synthetic resin portion 8b is disposed at the portion where the heat is applied. In short, the part facing the room with the sashes 2 and 3 closed is almost constituted by a synthetic resin part. Therefore, since the outside air temperature is effectively insulated to the indoor side when the sashes 2 and 3 are closed, the overall heat insulation is excellent, and dew condensation can be effectively prevented.

In particular, the synthetic resin portion 14b of the upper frame 14 is disposed over the entire length of the lower surface of the metal portion 14a, and a part thereof faces not only the room but also the outside with the shojis 2 and 3 closed. The hollow projection 22 of the synthetic resin portion 14b is in contact with the metal portion 14a of the upper frame 14 on the indoor side of the guide projection 21 of the outdoor sash 3. Therefore, the heat insulation performance is further improved.

When the sliding doors 2 and 3 are closed, almost all of the parts facing the outdoor side are metal parts 8a, 14a, 15a,
Since 16a appears, the metal part and the synthetic resin part clearly appear separately on the outside and the inside of the room, respectively, and the interior and the exterior have uniformity, respectively. And the product value is also improved. Although a part of the synthetic resin portion 14b of the upper frame 14 also faces the outside, this portion is blocked by the guide ridge 21 for the outdoor shoji of the metal portion 14a, so that it is difficult to see from the outside.
There is no unnatural appearance.

Since the resin piece 32 is disposed at a position facing the indoor side (the indoor side of the outdoor sash 3) with the sashes 2 and 3 closed, heat insulation is enhanced. Further, since the resin piece 32 is only attached to half of the entire length of the lower frame 15 and is not exposed to the outside of the room, the overall design is improved without hindering the uniformity of the design.

Further, the synthetic resin portions 14b, 15b, 16b and 8b of the window frame 1 and the frames of the shojis 2 and 3 can improve the strength and heat insulation of the synthetic resin portions by the hollow portions.

In addition, the upper ends of the sliding doors 2 and 3 rails on the indoor side of the lower frame 15 are exposed to the indoor side, but are negligible in terms of the overall heat insulation, and even if dew condensation occurs, Condensation in the lower frame 15 is naturally eliminated, and the upper frame 14
Unlike the case of the above, there is no problem in practical use since it does not sag.

Next, the above-described window configuration can be applied to a semi-external sliding window. That is, as shown in FIG. 5 and FIG. 6, the semi-external attachment is such that the middle part of the window frame 1 fits inside the window opening 17 of the building, so the basic configuration is the same as that of the external attachment. is there. The main differences from the external sliding window are the upper frame 14, the lower frame 15, and the vertical frame 16.
Are formed with mounting edges 18 and 40 for fixing to the outer peripheral surface of the window opening 17 and mounting edges 18a and 40a for fixing to the inner peripheral surface, respectively. Therefore, the same components as those of the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The effect of the semi-external sliding window is the same as that of the case of external mounting.
