BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double glazing structure provided with a curtain and a blind in a hollow layer.

[0002]

2. Description of the Related Art As a method of blocking solar heat or sunlight entering a room, there is a method of providing a curtain or a blind on a room side of a window and covering the entire surface of the window. Was. However, since these curtains and blinds protrude into the room, a sufficient space in the room cannot be secured, and there is inconvenience that dust and dirt are attached.

In recent years, in order to obtain a heat insulating effect such that the temperature in a room is maintained and an excellent soundproofing effect, a double glazing having two glass plates opposed to each other with a hollow layer interposed therebetween has been used. It has been proposed that curtains and blinds are provided in the hollow layer of the double-glazed glass, and that heat and light are blocked by operating from outside the window. In this way, the interior dust and dirt did not adhere to the curtains and blinds, and the interior space was secured.

[0004]

However, if a blind or the like is provided in the hollow layer of the double-glazed window, in order to open and close the blind, the opening / closing means usually needs to be opened from inside the hollow layer to the outside. In addition, it was not possible to obtain a double-glazed glass having an excellent heat insulating effect and a soundproofing effect, in which the hermeticity of the hollow layer was guaranteed.

On the other hand, when the airtightness of the hollow layer is made complete in order to obtain a double-glazed glass having an excellent heat insulating effect and soundproofing effect, the blinds and the like provided in the hollow layer can be externally operated. If a blind or the like is provided in the hollow layer in a closed state beforehand, it becomes impossible to illuminate through such a window.

Further, even when only a drive shaft such as a blind is guided to the outside of the double glazing and the blind is operated by the drive shaft, the hermetically sealed space is not provided due to poor airtightness due to fluctuations in atmospheric pressure and the like. It was extremely difficult to secure for a long time.

An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to provide a double-glazed glass structure which has not been known so far.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and at least two glass plates are formed so that a hollow layer is formed with a spacer interposed therebetween at the periphery. in a double glazing formed by spaced, a multilayer glass structure consisting of a drive shaft which can be opened and closed in conjunction to shield provided in the hollow layer, the spacer
