Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is intended to reliably control the operation of functional movable members, such as roll screens and blinds, which are enclosed in a space formed inside a double glazing, from the outside. The present invention relates to a laminated glass structure.

[0002]

2. Description of the Related Art A window glass itself having a function of blocking sunlight and a function of blocking a line of sight from the outside under a mechanical configuration is known as a non-hermetic seal formed inside a double glass. There is already known a blind glass or the like in which a functional movable member having a shielding function such as a blind or a roll screen is incorporated in the space of the above.

In this case, it is necessary to separately provide an external drive control mechanism for controlling the operation of the functional movable member, and by operating the drive control mechanism from outside. The functional movable member could be operated in a desired state.

[0004] Further, there is also a type in which the above-mentioned functional movable member is built in a double-layered glass. In this case, since the internal space must be kept in a closed state, it is formed using a magnetic material. It was necessary to control the operation of the functional movable member using magnets from the outside.

[0005]

By the way, even with the above-mentioned conventional structure, it is possible to impart a shielding function to the window surface of double glazing which does not need to keep airtightness in the internal space. Further, the operation of the functional movable member can be controlled even in a case where the functional portion is incorporated in the multi-layered glass while the space is kept closed.

However, in the case of double-glazed glass, it is necessary to keep the space formed between the glass plates separated by the spacers in a hermetically sealed state. It is structurally difficult to enclose and install a functional movable member having a shielding function, such as a screen or a roll screen, because of the space for installing a drive control mechanism that requires external attachment.

[0007] In the case where the operation is controlled using a magnet from the outside, the function cannot be sufficiently exhibited when the thickness of the glass sheet constituting the double-glazing is relatively large. was there.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the prior art, and its structural feature is that it is provided between glass plates separated by a spacer. A multi-layer glass having a built-in functional movable member having a rotation axis that freely supports the control of the rotation direction via an external drive control mechanism in a space formed, and is provided with an externally mounted glass. The drive control mechanism allows the shaft end of the rotary shaft with the sealing portion interposed in the concave portion provided at the corner portion of the double-glazed glass to go out and freely imparts bidirectional rotary motion to the rotary shaft. It was arranged in.

In this case, the drive control mechanism fixes the driven gear to the shaft end having the rotating shaft as the driven shaft, and the intermediate gear fixed to the driving shaft which is supported by the concave portion of the composite glass. In addition to being formed by meshing with the driven gear,
By attaching a rotation operation member to a pulley fixed to the shaft end having a rotation shaft as a driving shaft via an operation hole provided on one glass plate surface defining the recessed portion. It may be arranged such that the rotation motion can be given from outside freely.

[0010]

For this reason, the functional movable member incorporated in the space portion of the double-glazed glass is moved with respect to the rotating shaft through the shaft end portion which is projected to the recessed portion of the corner portion by the external drive control mechanism. The operation can be controlled by giving a bidirectional rotational motion.

In addition, since the shaft end of the rotary shaft is projected to the recessed portion with the sealing portion interposed, the shaft is externally mounted while ensuring the airtight state of the space in which the functional movable member is built. Can be disposed compactly.
