Description

  The present invention comprises a window frame, a movable shoji that is movably built in the in-plane direction on the inside of the window frame, and a fixed shoji that is immovably fixed in the in-plane direction on the inside of the window frame. The present invention relates to an improvement of a one-way window device.

  A window device is provided at the opening of the building frame for the purpose of lighting and ventilation. The frame material of the window frame and the window material for window shoji constituting such a window device are generally made of an aluminum alloy. However, since aluminum alloy has high thermal conductivity, the temperature of the surface of the indoor side of the frame material and frame is close to the temperature of the outside air, which may not only impair the air conditioning effect in the room, but also in winter Condensation may occur on the floor, and the floor and curtains may be soiled.

  In view of such circumstances, for example, Patent Document 1 discloses a structure in which a frame member and a saddle member are configured by connecting an outdoor frame made of aluminum alloy and an indoor frame made of synthetic resin. Yes. In the case of the first example having such a conventional structure, since the thermal conductivity of the synthetic resin constituting the indoor frame is low, the temperature of the indoor frame can be easily kept constant regardless of the temperature of the outside air. For this reason, the air conditioning effect in the room can be improved and the occurrence of condensation can be prevented. However, in the case of the first example having such a conventional structure, durability and weather resistance are lower than in the case where the frame material and the entire brace material are made of an aluminum alloy. Further, for example, when assembling the window device, it is necessary to consider the effects of sparks and scratches caused by welding.

  In view of such circumstances, for example, Patent Document 2 discloses a frame material and a saddle member made of an aluminum alloy outdoor frame and an indoor frame, and a synthetic resin that connects the outdoor frame and the indoor frame. The structure comprised from the heat insulating material of this is disclosed. In the case of the second example having such a conventional structure, a synthetic resin heat insulating material having a low thermal conductivity exists between the outdoor frame and the indoor frame. The amount of heat transfer between the two is reduced. For this reason, the temperature of the indoor side frame can be easily kept constant regardless of the temperature of the outside air. Therefore, the indoor air conditioning effect can be improved and the occurrence of condensation can be prevented. Further, the durability and weather resistance can be improved as compared with the case where the indoor frame is made of synthetic resin. In addition, considerations such as the influence of sparks and scratches due to welding are also reduced during the assembly of the window device.

For example, a heat insulating material that connects the outdoor frame material and the indoor frame material is disposed in a portion that aligns with the external sliding element that is a movable shoji in the out-of-plane direction of the window frame that constitutes the one-pull type window device ( When a heat insulating line composed of a plurality of heat insulating materials is formed), the heat insulating performance of the portion where the outer shoji is placed can be secured, but the heat insulating material is present outside the inner shoji which is a fixed shoji. In the window frame, the temperature of the indoor side portion of each frame member that supports the shingles easily changes according to the temperature of the outside air. As a result, there is a possibility that problems such as damage to the air-conditioning effect and easy formation of condensation and the like.
In view of the circumstances as described above, the present invention is a structure of a one-way window device capable of ensuring the heat insulation performance of both a portion in which a movable shoji is arranged and a portion in which a fixed shoji is arranged in the window frame.

  When implementing the present invention as described above, for example, the upper frame constituting the window frame is positioned on one side (above the movable shoji in the closed state) with respect to the in-plane direction, each having a different cross-sectional shape. The movable upper frame and a fixed upper frame located on the other side (above the fixed shoji) in the in-plane direction can be used.

It can comprise from a lower frame and the fixed side lower frame located in the other side (below a fixed shoji) about an in-plane direction.

Furthermore, when implementing this invention, the said movable shoji can be used as an external shoji and the said fixed shoji can be used as an internal shoji.
Alternatively, the movable shoji can be an inner shoji and the fixed shoji can be an outer shoji.
Further, when carrying out the present invention, each frame member constituting the window frame is made of, for example, an outdoor frame member made of aluminum alloy and an indoor frame member, for example, synthetic resin such as polyamide 6 (nylon 6). It is possible to adopt a structure that is connected via a strip-shaped (plate-shaped) heat insulating material.
Examples of the aluminum alloy include A6063S-T5 material (JIS H 4100), that is, 0.20 to 0.6% by weight of Si, 0.35% by weight or less of Fe, and 0.10% by weight or less.
