The extending portion 28 and the inner peripheral surface portion (lower wall) of the inner mold member 23
23d and the extending portion 27 of the outer mold member 22 together form a glass attachment recess 29. Projecting edges 30 and 31 that protrude inward from each other are formed at the tip edges of both the extensions 27 and 28, respectively. The lower frame 32 of both sliding doors 19, 20 is also constructed by fitting an outer frame 33 made of aluminum and an inner frame 34 made of hard synthetic resin such as vinyl chloride. The outer surface 33a and each opposing surface are covered with the inner mold material 34, and the inner mold material 3
4 and the inner surface 33 of the outer mold member 33
A gap 32a is formed between the mold members 33, 3 by a protrusion 34b protruding from the former and
A glass mounting recess 39 is formed by the extending portions 37 and 38 having four projecting edges 35 and 36 and the inner circumferential surface portion (upper wall) 34c of the inner mold member 34. In addition, an airtight tongue portion 40 is integrally formed to protrude from the outer peripheral surface portion (lower wall) 34d of the inner mold member 34,
An airtight material attachment recess 41 is formed, and an elongated airtight material 42 made of a flexible material such as mohair is fitted into this recess 41. The airtight material 42 fits into the rail groove 17 of the lower frame 2 and comes into sliding contact with the bottom surface thereof, that is, the top surface of the long sill plate 16. A curved recess 16' (FIG. 1) is formed on this upper surface to allow a portion of the door roller to fall when the sliding doors 19, 20 are closed. Therefore, when the sliding doors 19 and 20 are closed, a portion of the door roller falls into the recess 16' and lowers a little, the airtight material 42 comes into pressure contact with the upper surface of the long sill plate 16, and the airtight tongue 40 touches the bottom frame. 2, and the lower stile 32 of the sliding door 19, 20 and the lower frame 2
The gap between them is tightly sealed. The position of the recess 16' can be adjusted by cutting the long sill plate 16 to an appropriate length on site and fitting it into the long groove 15. As shown in FIG. 3, the door stop frame 26 is also constructed by fitting an outer mold material 43 made of aluminum and an inner mold material 44 made of hard synthetic resin such as vinyl chloride, and the outer surface 43a of the outer mold material 43 and Each of the opposing surfaces except for the surface of the extending portion continuous thereto is covered with the inner mold material 44, and between the inner surface portion 44a of the inner mold material 44 and the inner surface 43b of the outer mold material 43, a protrusion 44b formed protruding from the former is provided. Thus, a gap 26a is formed, and a glass mounting recess 49 is formed by the extensions 47, 48 having the projecting edges 45, 46 of both mold members 43, 44 and the inner circumferential surface portion 44c of the inner mold member 44. An airtight tongue portion 50 is integrally formed to protrude from the outer peripheral surface portion 44d of the mold member 44. The meeting frame 25 is also constructed by fitting an outer mold material 51 made of aluminum and an inner mold material 52 made of hard synthetic resin into each other, and the opposing surface excluding the outer surface 51a of the outer mold material 51 and the surface of the extension part continuous therewith is made of an inner material. Shape material 52
At the same time, a gap 25a is formed between the inner side surface 52a of the inner mold member 52 and the inner surface 51b of the outer mold member 51 by a protruding ridge 51c formed on the latter. A glass attachment recess 57 is formed by the extensions 55 and 56 having edges 53 and 54 and the inner circumferential surface portion 52b of the inner mold member 52. Inner frame material 52 of the meeting frame 25 of the outer sliding door 19
has an airtight tongue 5 at two places, one side edge and the middle part.
8, 59, and the meeting frame 2 of the inner sliding door 20
The outer mold member 51 of No. 5 forms an airtight tongue portion 60 only on one side edge. Furthermore, a protrusion 61 that collides with the airtight tongue portion 59 is formed on the outer mold member 51 of the inner sliding door 20.
When both sliding doors 19, 20 are closed, the gap between their meeting frames 25 is closed by their airtight tongues 58, 5.
9 and 60, it is triple-tightly closed. The outer circumferential surface portion 52d of the inner mold member 52 is formed into a U-shape in cross section. As above, upper stile 21, lower stile 32, meeting stile 2
5 and the door stop frame 26 are both constructed by fitting an outer mold member made of aluminum and an inner mold member made of hard synthetic resin that covers the outer surface thereof and each opposing surface. This is because the outer mold material maintains strength and weather resistance, and the inner mold material maintains heat insulation properties. Further, the reason why a gap is formed between the inner surface of the outer mold member and the inner side surface of the inner mold member is to further improve heat resistance and soundproofing effects. Each of the sliding doors 19 and 20 has a single glass plate 62 fitted into the glass mounting recesses 29, 39, 49, and 57 of the upper stile 21, lower stile 32, meeting stile 25, and doorstop stile 26, respectively. This fitting is carried out in the following manner using elongated glass fixing members 63 on the four sides of the frame. That is, to explain the lower stile 32 as a representative with reference to FIG. 4, the glass fixing member 63 is integrally molded with a hard synthetic resin such as vinyl chloride, and has a recess 64 along the entire length of the middle part, and a recess 64 at the opening thereof. Hollow shoulders 65, 65 are formed protrudingly on both outer edges, a convex shape 66 is formed on the inner edge of one of the shoulders 65, and a projecting edge 67 is formed on the outer edge of both shoulders 65, 65. 67 is formed to protrude, and airtight protrusions 63', 63' made of hard synthetic resin (soft vinyl chloride, etc.) are integrally molded on the inner edge of the other shoulder portion 65 and the outer corner edge of the recessed portion 64. This is what I did. This glass fixing member 63 is attached to its both shoulders 65,
65 is brought into contact with the inner bottom surface of the glass attachment recess 39 of the lower stile 32 (the upper surface of the upper wall of the inner mold material 34), and a pair of protrusions 7 protruding from this inner bottom surface.
0 and 70, the lower edge of the glass plate 62 is inserted between the extending portion 37 of the outer mold member 33, and silicone rubber is inserted between the lower edge and the extending portion 37. The lower edge of the glass plate 62 is held between the gas-tight protrusion 63' on the outer corner edge of the glass fixing member 63 and the gasket 68 by interposing a gasket 68 made of an elastic material such as the like. According to such a fixing structure, the outer surface of the recess 64 of the glass fixing member 63 and the extending portion 38 of the inner mold member 34
Since there is a gap between the glass plate 62 and the glass plate 62, condensed water on the inner surface of the glass plate 62 can flow into the glass mounting recess 39. In other words, the glass attachment recess 39 can be used as a condensation water drainage gutter. Moreover, due to the above-mentioned fixing structure, the glass plate 62
The space between the lower stile 32 and the lower stile 32 is insulated by the glass fixing member 63, and is airtightly closed by the gasket 68 and the airtight protrusion 63'. The same applies to the space between. In the above embodiments, the present invention is applied to sliding doors, but it may be applied to other types of sliding doors, and it may be applied not only to sliding doors but also to hinged doors.

に実施できる。 As is clear from the above description, the inner window device of the present invention has the following effects. The upper frame, lower frame, and left and right vertical members of the inner window frame are provided with insulation bars between the inner and outer sash bars, and also between the sash plate for maintaining the distance and the inner window frame. Effectively insulated. In the stile of the sliding door, the surface of the metal outer mold material except for the outer surface is covered along with the synthetic resin inner mold material, so that the heat insulation effect between these two mold materials is good. Since a gap is formed between the inner surface of the outer mold material and the inner side surface of the inner mold material, the heat insulation and soundproofing effects are even better. The glass fixing member that fixes the edge of the glass plate in the glass mounting recess is integrally molded with synthetic resin with a recess 64 formed in the entire length of the intermediate part, and both shoulders of the member are in contact with the inner bottom surface of the glass mounting recess. Then, the peripheral edge of the glass plate is fitted into and fixed between a pair of protrusions protruding from the inner bottom surface, and the peripheral edge of the glass plate is inserted into the recess 6.
4 and the extending portion of the outer mold member together with a packing made of an elastic material.
Since a condensation water drainage gutter is formed between the other outer surface and the extension of the inner mold material, the glass plate is firmly fixed and the area is insulated, and the inner surface of the glass plate is The plate on which condensed water is generated can be received by flowing into the condensed water drain gutter. When the sliding door is closed, a portion of the door wheel falls into the recess and the entire sliding door lowers, and the flexible airtight material attached to the bottom of the lower stile comes into pressure contact with the inner bottom surface of the rail groove in the lower frame of the inner window frame. Therefore, the gap between the lower stile of the sliding door and the lower frame of the inner window frame can be firmly and airtightly closed, and the sliding door can be closed in a stable state. Since the long sill plate is fitted into the long groove formed on the upper surface of the lower frame of the inner window frame and the recess is formed on the upper surface of the elongated sill plate, the position of the recess can be adjusted as appropriate on site. The top surface of the long sill plate is slightly lower than the top surface of the bottom frame to form a rail groove, and the door roller can roll along this rail groove, allowing the sliding door to open and close smoothly and making it easier to clean the area. can also be easily implemented.
