Description

[Detailed explanation of the idea] The present invention relates to a dew-proof sash.

Generally speaking, the dew-proofing method for aluminum sash is to separate the indoor side from the outdoor side with a frame filled with heat insulating material to prevent direct conduction of heat.

The present invention is a further improvement of this technique, and embodiments will be described below with reference to the accompanying drawings.

FIG. 1 is a sectional view of a sliding window.

1 is an outer frame, 2 is an inner frame, and the two are partitioned with a heat insulating material a such as polyurethane foam to prevent direct conduction of heat.

3 is the upper stile of the sliding window, and in the example shown in the figure, it is double glazed.

4 is a weather strip fixed to the upper part of the upper stile 3;
It contacts the rail 5 of the outer frame 1 and prevents rainwater from entering from the outside.

Reference numeral 6 is a heat insulating material according to the present invention, which has a cross-sectional shape and is attached to cover the inner surface of the inner frame 2 and the inner surface of the joint between the outer frame and the inner frame.

The heat insulating material 6 is made of semi-rigid vinyl chloride, for example, and is set by locking protrusions 7 and 8 that are integrally provided on the inner frame 2 and outer frame 1.

Note that the heat insulating material 6 is provided with a locking groove corresponding to the locking protrusion 7.

In the example shown in the figure, the heat insulating material 6 is fixed by a locking protrusion and a groove, but it can also be fixed by adhesive, by the repulsive force of the material, or by being inserted into the cross section of the profile. etc., by appropriate means.

With the above configuration, there is a cold air layer 9 cooled directly or indirectly via the weather strip 4 or rail 5, etc. in the area marked with xxx in FIG. 1, but there is also a heat insulating material 6. Therefore, there is no direct contact between the cold air layer 9 and the inner frame 2.

Therefore, heat conduction in this part is prevented, and dew condensation can be prevented.

Figure 2 shows the structure of the side frame of a sliding window, in which the outer frame 1a and the inner frame 2a are connected by a heat insulating material a, and the inner frame 2a
In addition, a heat insulating material 6 having an angular cross-section is fixed to a portion inside the joint portion that contacts the cold air layer 9 by a locking protrusion and a groove.

Although not shown, a heat insulating material is similarly provided in the lower frame portion of the sliding window at the portion that contacts the cold air layer of the inner frame.

FIG. 3 shows the structure of the fitted window. As in the case of FIG. 1, the upper frame is composed of an outer frame 1C and an inner frame 2C, and the joint portion thereof is thermally partitioned by a heat insulating material a.

In this case as well, the heat insulating material 6 is fixed to the outer surface of the inner frame 2C by the locking protrusions and grooves to avoid contact with the cold air layer 9.

In the case of Fig. 4, the structure of the side frame part of the fitted window is shown,
In the side frame, an outer frame 1d and an inner frame 2d are connected via a heat insulating material a.

A heat insulating material 6 is fixed to the outer surface of the inner frame 2d by engagement with the locking protrusions and grooves.

Similarly, contact with the cold air layer 9 is avoided to prevent dew condensation.

Although not shown, a heat insulating material is similarly fixed to the lower frame portion to prevent contact between the inner frame and the cold air layer.

According to the present invention as described above, (1) In addition to the conventional structure in which the inner frame and the outer frame are thermally partitioned by the heat insulating material a, the inner frame is further partitioned from the cold air layer outside by the heat insulating material 6. Therefore, the dew resistance in this area has been further improved.

(2) Since the heat insulating material 6 is installed in a place that is less visible than the indoor side, it does not impair the aesthetic appearance.

(3) Since the heat insulating material 6 is fixed to the corner of the inner frame, it does not affect the use of the sash in any way.

(4) Since it adheres to the surface of the aluminum profile, it also has the secondary effect of protecting the profile.
