2. Description of the Related Art A sash in which an inner sash and an outer sash are moved in a sash frame, such as a sliding sash and a lifting sash, is often provided with a guide ridge for guiding the movement of the sash. There are two types of guide ridges, such as rails, on which a single door rolls, and ones on both sides of a movement path to form guide grooves. In the heat-insulating sash, the frame material that composes the sash frame and the frame material (frame material) that composes the shoji are all separated into indoor and outdoor profiles, and heat transfer is blocked by a heat-insulating bridge. And then joined. In this case, the shape and the heat-insulating bridge may have different colors and caulking traces.In order to prevent the heat-insulating material from being directly exposed to direct sunlight or the outside air, it may be deteriorated early. A separate member 45 that normally hides the thermally insulated connection (FIG. 1)
Is used.

Both the inside and outside sections need to have a structure that can withstand the load of the shoji, and both sections have a hollow structure or a thick wall, and are structurally material (such as wall pressure). Also need to be rugged. Also, if the cross-section structure is complicated, such as forming a hollow part, to increase the structural strength, it takes a lot of labor and cost to create the extrusion die required for molding,
Not economic. In addition, the insulation frame that combines the indoor side section and the outdoor side section with a heat insulating material may have a difference in the direction and size of the force acting on the indoor side section and the force acting on the outdoor side section. ,
Structurally, the connection point by the heat insulating material is weak. Therefore, it is originally not preferable to dispose the guide ridge of the inner sash and the guide ridge of the outer sash on both sides of the heat insulating material.

On the other hand, as shown in FIG. 1, in the lower frame 2 of the heat-insulating sash 1, the indoor-side shape member 2 a and the outdoor-side shape member 2 b are thermally cut off and joined by the heat-insulating bridge 3. 2b

The members 32b are arranged in a width dimension extending over the rising portion 37. The second auxiliary profile 34 has a length corresponding to the left and right dimensions of the inner sash 5 on the side where the inner sash 5 is opened, and extends from the rising wall 36 of the indoor profile 32a to the outdoor profile 32b.
The width dimension is set so as to extend over the rising portion 37 of the outer sash 6 and the position close to the indoor side surface of the outer sash 6. Each of the first and second auxiliary profiles 33 and 34 is provided with a guide ridge 4a of the inner sash 5 on the upper surface, and a portion extending from the guide ridge 4a to the indoor side is a cover portion 46. Further, mounting portions 38 and 39 projecting downward on the outdoor side are provided. The guide ridges 4a for the inner shoji on the first and second auxiliary profiles 33, 34 are provided at equal distances from the mounting portions 38, 39 toward the indoor side.

The seal piece 35 (FIG. 7) is made of a hard synthetic resin and has heat insulation performance, is provided with cuts on both left and right sides, and is provided with a horizontal portion of the first auxiliary profile 33 and the second auxiliary profile 34. The upright portion of the guide ridge 4a for the inner sash can be inserted. That is, the first and second auxiliary profiles 33 and 34 on both sides are connected by the seal piece 35. In the joined first and second auxiliary profiles 33 and 34, the guide ridges 4 a for both sides of the inner sash are aligned in a single line, and between the guide ridge 4 a for inner sash and the auxiliary profiles 33 and 34.

The heat insulating material 43 is formed from a portion where the second auxiliary profile 34 is in contact with the rising portion 36, a U-shaped section surrounding the mounting portion 39 and the mounting portion 39 of the second auxiliary profile 34. It consists of a part that covers the back surface of the part that extends to the outside of the room. Also in this case, similarly to the case of the first auxiliary profile 33, the force acting on the guide ridge 4a for the inner sprouts can be borne by the outdoor profile 32b.

With the above-described structure, the heat insulating sash 1 has a structure in which all the frame members constituting the heat insulating sash are separated into the indoor side and the outdoor side, and are joined by a heat insulating material, so that the heat insulating performance is high. In particular, the second auxiliary profile 34, which is on the indoor side of the outer sash 5 when the sash is closed, is thermally shielded from the low-temperature outdoor profile 32b by the heat insulating material 44, and at the same time, by the seal piece 35. , And is shielded from the outside air that enters the room from the mating section. Since only the outer sash guide ridges 4b are provided on the outdoor side profile 32b, and the inner sash guide ridges 4a are not provided on the indoor side profile 32a, the cross-sectional configuration can be simplified. Further, since the force acting on the guide ridge 4a for the inner sash provided on the first and second auxiliary profiles 33, 34 is supported by the profile 32b for the outer sash, the guide ridge 4b for the outer sash is formed. The structure of the robust outdoor shape member 32b provided can be effectively used. Thereby, the manufacturing cost of the heat insulating sash can be reduced as a whole.
Further, as in the conventional case, the loads of the inner sash 5 and the outer sash 6 are concentrated on the outdoor-side profile 32b, so that a displacement occurs at a joint portion of the heat-insulating material between the indoor and exterior-side profiles 32a, 32b.

Protect from direct sunlight and the open air. that's all,
Although the embodiment has been described centering on the lower horizontal frame of the sash, the present invention can also be applied to an upper horizontal frame of the sash and a vertical frame having a guide ridge for guiding a shoji. The guide ridge may be a rail type in which a door roller rolls on its top surface, or may be a type in which a sliding door is guided between two guide ridges. The connection between the indoor side shape member and the outdoor side shape member may be performed insulated, and the heat insulating coupling member is not necessarily required. For example, the ends of the indoor side section and the outdoor side section,
It is also possible to connect them with a heat insulating sealing material therebetween. In this case, the airtightness of the combined portion of the inner and outer sashes is achieved by an airtight block that moves together with the sashes and fits when the sashes are closed as in the related art.

According to the first aspect of the present invention, the first and second auxiliary members provided with the guide ridges for the inner shroud are thermally separated from the outer side members of the heat insulating frame or the outer shoji. Since it is shut off, the heat insulating performance of the heat insulating sash is improved. When the shoji is closed, dew condensation hardly occurs on the guide ridge for the inner shoji exposed to the indoor side. The first and second auxiliary shapes and the cover provided with the heat-insulating coupling member protect the heat-insulating material connecting the indoor-side shape and the outdoor-side shape from direct contact with direct sunlight and outside air. The durability of the insulating sash is improved. According to the configuration described in claim 2, since the acting force received by the guide ridge for the inner sash of the auxiliary profile is received by the outdoor profile, the indoor profile has exceptional strength as the lower frame structure of the heat insulating sash. There is no need to take this into account, and it can be merely a decorative frame.
In addition, displacement hardly occurs between the indoor-side profile and the outdoor-side profile connected by the heat insulating material. According to the third aspect of the present invention, the thermal insulation between the first and second auxiliary profiles is achieved by using the heat insulating coupling member together with the operation and effect of the first aspect as the heat insulating sash. In addition, it is possible to more reliably maintain the airtightness at the joining place of the inner shoji and the outer shoji when the shoji is closed, and protect the heat insulating material at the joining place. Further, since the grooves and projections for positioning the first auxiliary profile and the second auxiliary profile can be provided in the heat insulating coupling member, the first auxiliary profile and the second auxiliary profile can be easily connected, and They can be reliably connected. According to the configuration of the fourth aspect, in the lower frame having a structure in which the first and second auxiliary profiles are connected by the heat-insulating coupling member, the indoor-side profile is exceptionally strong as the lower frame structure of the heat-insulating sash. There is no need to take this into account, and it can be merely a decorative frame. In addition, displacement is less likely to occur between the indoor side profile and the outdoor profile connected by the heat insulating material and between the first and second auxiliary profiles.
