Description

  This invention, for example, by attaching to a window glass of an existing glass window, or when assembling a glass shoji, it is attached to a shoji frame together with the window glass to prevent condensation and to insulate the room from the outside Condensation prevention / insulation device

Condensation is caused when the shoji frame such as an aluminum sash and window glass are cooled by the low outdoor temperature, and when the temperature of the indoor surface of the window glass is significantly lower than the indoor temperature, water vapor contained in the indoor air It is generated by liquefying and becoming water droplets and adhering to the window glass.
The water droplets condensed on the window glass not only pollutes the indoor curtain fabric, but also reduces the indoor heating effect in the winter and generates energy loss.
In order to prevent this, it is known that the window glass has a double structure.

However, since it is difficult to make the window glass a double structure with respect to the existing glass window, a spacer tape is attached along the outer peripheral portion of the window glass in the shoji frame, and the window glass and An anti-condensation / insulating device for windows has been proposed in which a film for heat insulation is attached to form an air layer in between to prevent condensation and to insulate the room from the outside.

First, similarly to the window condensation prevention / heat insulation device M of the reference example , the frame body 21 is assembled, the film 31 is attached to the assembled frame body 21, and then the decorative plate 41 is attached to the film 31.
Then, a double-sided adhesive tape (not shown) is attached to the surface of the frame body 21 to be attached to the plate body 11 or attached to the portion corresponding to the inside of the plate body 11 to which the frame body 21 is attached. After the tape (not shown) is wrapped and pasted, the frame body 21 is overlaid on the plate body 11, and the frame body 21 is pasted on the plate body 11 so that both the openings 11h and 21h are overlaid. The assembly of the prevention / heat insulation device M is completed.

Next, the attachment of the window condensation prevention / heat insulation device M of the fourth embodiment to the glass shovel S will be described.
By condensing the plate body 11 of the window dew prevention / heat insulation device M assembled as described above on the window glass G and assembling the plate body 11 together with the window glass G in the same manner as a normal glass shoji S, dew condensation for windows The attachment of the prevention / heat insulation device M to the glass shovel S is completed.
And the assembly glass shoji S is attached to a window frame.
Note that when the window dew condensation prevention / heat insulation device M is attached to the glass shoji S, a sealed air layer a having a thickness of 2 mm or more is formed between the window glass G and the film 31, as shown in FIG. The

According to the window condensation prevention / heat insulation device M of the fourth embodiment of the present invention, the same effect as the window condensation prevention / heat insulation device M of the reference example can be obtained.
And since the plate body 11 which attached the frame body 21 and whose outer shape is the size of the window glass G is provided, when attaching the glass window G to the shoji frame F, a sealing material such as rubber packing P is used. By attaching the plate 11 to the shoji frame F together with the glass window G, the window dew condensation prevention and heat insulation device M can be attached to the glass shoji S from the beginning or at the time of refurbishment.
Further, since the plate body 11 protrudes outside the frame body 21, the portion of the plate body 11 protruding outward from the frame body 21 is used as the side plate portion 23 of the first embodiment, thereby providing a crescent receiver. It can also be attached to the glass shoji S.

In the above-described embodiment, an example in which the sizes of the openings 11h, 21h, and 41h are the same is shown. However, it is desirable to slightly reduce the opening on the indoor side.
An example in which the fixing screw is a countersunk screw 25 and the countersunk screw 25 is not protruded to the outside of the frame body 21 is shown. However, a fixing screw other than the countersunk screw 25 is used and similarly protrudes to the outside of the frame body 21. You may make it not.
Furthermore, although the example which made the adhesive material which adhere | attaches each part the double-sided adhesive tape was shown, as long as it can adhere | attach and seal | stick in the same way, you may use another adhesive material.
Moreover, the sealing material which seals between the shoji frame F and the window glass G which showed the example which seals between the shoji frame F and the window glass G with the rubber packing P can be similarly sealed, Other sealing materials such as putty may be used.
When slack occurs in the film 31 attached to the frame body 21, the slack can be removed by blowing hot air on the film 31.

And although the recessed part 23 was not provided in the side-plate part 23 in 3rd Example, predetermined thickness is provided between the side-plate part 23 of the four sides of the frame 21, and the window glass G like 2nd Example. By providing the recess (23a) forming the air layer a independently or around the recess, an effect of preventing dew condensation can be obtained even in the side plate portion 23 portion.
Further, in the fourth embodiment, the plate body 11 is not provided with a recess. However, as in the second embodiment, the window glass G is provided on the four sides of the plate body 11 located outside the frame body 21. By providing the recesses for forming the air layer a having a predetermined thickness independently or around the recesses, a dew condensation preventing effect can be obtained even at the four side portions of the plate body 11 located outside the frame body 21. be able to.
