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 recesses 29, 39, 49, and 57 of the upper stile 21, lower stile 32, meeting stile 25, and door stop 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 from a hard synthetic resin such as vinyl chloride, and has a concave groove portion 64 running the entire length of the middle portion.

Therefore, the space between the glass plate 62 and the lower stile 32 is insulated by the glass fixing member 63 and hermetically closed by the gasket 68 and the airtight protrusion 63'. is the glass plate 62
The same goes for the spaces between the stile and the other three sides. 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.

[Effect of the idea]

As is clear from the above description, the inner window device of the present invention has the following effects. In the sliding door stile, each opposing surface except for the outer surface of the metal outer mold material and the surface of the extension part that continues with it is covered with a synthetic resin inner mold material along it, so that the insulation effect between these two mold materials is improved. 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. Since the space between the outer mold member and the glass plate is double-insulated by the inner circumferential surface of the inner mold member and the glass fixing member made of synthetic resin that fits into the glass mounting recess, the insulation effect between them is also good. Expanding this further, the glass fixing member that fixes the edge of the glass plate within the glass attachment recess is fitted into the glass attachment recess with the opening surface of the groove 64 formed over the entire length of the intermediate portion facing outward. Then, the shoulders on both outer edges of the opening surface and the protruding edge on the outer edge are engaged and fixed to the protruding edge of the glass mounting recess, and the edge of the glass plate is attached to the concave groove 64 together with a packing made of an elastic material. Since the glass plate is tightly sandwiched between the glass plates, the glass plate is firmly fixed and the relevant portion is properly insulated. When the sliding door is closed, a portion of the door wheel falls into the recess and the entire sliding door descends, and the flexible airtight material attached to the bottom of the lower stile comes into pressure contact with the inner bottom of the rail groove in the bottom 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 be rolled along this rail groove, allowing the sliding door to open and close smoothly and making it easier to clean the area. Easy to implement.
