[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double glazing structure having a curtain and a blind in a hollow layer.

[0002]

[Prior art]

 As a method of blocking the solar heat and sunlight that enter the room, there is a method of covering the entire surface of the window with a curtain or blind on the indoor side of the window, thus blocking the heat and light. However, since these curtains and blinds overhang inside the room, there was inconvenience that the space inside this room could not be secured sufficiently and that dust and dirt were attached.

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

[0004]

[Problems to be solved by the device]

 However, if the hollow layer of the double-glazed glass window is provided with a blind or the like, in order to open and close the blind, the opening / closing means usually has to communicate from the inside of the hollow layer to the outside, and the hollow layer is sealed. It was not possible to obtain a double glazing having a good heat insulation effect and a soundproofing effect.

On the other hand, in order to obtain a double glazing having an excellent heat insulating effect and soundproofing effect, when the hollow layer is completely closed, the blind and the like provided in the hollow layer can be operated from the outside. If this is not possible, and if a blind or the like is provided in the hollow layer in the closed state in advance, it becomes impossible to illuminate through such a window.

Further, even when only the drive shaft of the blind or the like is guided to the outside of the double-glazing unit and the operation of the blind or the like is performed by this drive shaft, the hermetically sealed space is not formed due to poor airtightness due to atmospheric pressure fluctuations 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 drawbacks of the prior art, and to newly provide a heretofore unknown double-glazing structure.

[0008]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and at least two glass plates are spaced apart from each other so that a hollow layer is formed with a spacer interposed therebetween, and the peripheral parts are separated from each other. A double glazing structure comprising a sealed double glazing and a drive shaft which can be opened and closed by interlocking with a shield provided in the hollow layer, wherein one end of the drive shaft is attached to the spacer. It protrudes to the outside of the double glazing from the provided through-hole, and the outer periphery of the drive shaft on the hollow layer side is equipped with a cap that abuts the spacer so as to cover the opening of the through-hole. Between the surface of the cap that contacts the spacer and the spacer, a sealing member is pressed and fitted to the cap so as to surround at least the opening of the through hole. In the gap with the shaft The double-glazing structure O-ring for closing the gap, characterized in that it is interposed is to provide new.

Further, according to the present invention, a cap having a thread on the outer periphery on the side of the through hole is screwed into the through hole having an inner periphery as a screw hole. Thus, the sealing member arranged on the surface of the through hole of the spacer around the opening on the hollow layer side may be pressed to fasten the cap to the through hole. It may be.

[0010]

As described above, according to the present invention, in the double glazing in which the shield such as a blind is provided in the hollow layer, the drive shaft for opening and closing the shield has a through hole protruding to the outside of the double glazing. The drive shaft is guided to the outside through this through hole, and these shields are operated from the outside.

A through hole for projecting a drive shaft connecting the inner side and the outer side of the multi-layer glass to the outside is provided between the cap, the sealing member fitted by the cap and the spacer, and the cap and the drive shaft. The hollow layer is closed by the O-ring, and the hollow layer does not communicate with the outside through the through hole, so that the hermeticity of the double-layer glass is maintained.

【Example】

 The present invention will be described in detail below with reference to the drawings.

FIG. 1 is an enlarged cross-sectional view of an essential part showing the basic structure of the present invention, and FIG. 2 is a schematic perspective view showing the basic structure of the present invention. A multi-layer glass 13 composed of two facing glass plates 3 which are spaced from each other so as to form a hollow layer 9 with a spacer 2 interposed therebetween and whose peripheries are sealed is a shield made of a blind in the hollow layer 9. This shield 10 is linked with the drive shaft 4 and can be opened and closed by the rotation of the drive shaft 4.

The spacer 2 has a through hole 5 through which the drive shaft 4 protrudes from the inside of the hollow layer 9 of the double glazing 13, and the through hole itself is a screw hole. The drive shaft 4 on the hollow layer 9 side is provided with a cap 41 on the outer periphery of the drive shaft 4 on the hollow layer 9 side with a slight gap provided so that the drive shaft 4 rotates smoothly. The opening on the side of the hollow layer 9 is covered from the side of the hollow layer 9.

The illustrated drive shaft 4 has an enlarged shaft portion 23 whose portion on the hollow layer side is enlarged, while the cap 41 is provided with a concave portion 24 in which the enlarged shaft portion 23 is housed. It also has a sleeve portion 25 that is inserted into the through hole 5. The drive shaft 4 is configured to rotate about the shaft of the drive shaft 4 in the concave portion 24 and the sleeve portion 25 of the cap 41. If necessary, a sealing material may be interposed between the sleeve portion 25 of the cap 41 and the through hole 5 in order to enhance the sealing performance.

Between the surface of the cap 41 in contact with the spacer 2 and the spacer 2, there is elasticity and flexibility so as to surround at least the opening on the hollow layer side of the through hole 5. A sealing member 21 made of a synthetic resin is fitted, and the sealing member 21 has a cap 41 having a screw thread on the side of the through hole 5 that is screwed into the through hole 5 to close the cap 41. By being brought into contact with the spacer 2 and tightened in the through hole 5, it is pressed by the cap 41 and the spacer 2 and closes the inside and outside of the double-glazing unit which is communicated by the through hole 5.

Further, one or a plurality of O-rings 22 are interposed in the gap between the outer circumference of the drive shaft 4 and the inner wall of the concave portion 24 of the cap 41. The O-rings 22 are the rotations of the drive shaft 4. The gap that is provided to ensure the safety of the double-glazed glass is secured by closing the gap.

Here, it goes without saying that the multi-layer glass structure according to the present invention is not limited to the above-mentioned embodiment. For example, as a means for joining the cap to the spacer, the cap and the spacer are used.

Is particularly preferable.

Further, the sealing member is preferably made of an elastic and flexible synthetic resin or rubber, or a soft synthetic resin or rubber so that the sealing member is pressed by the cap and the spacer to obtain excellent sealing performance. Especially, it is preferable to use silicone rubber, fluororubber, etc., which are excellent in oil resistance, durability and heat resistance.

Further, the O-ring that closes the gap between the drive shaft and the cap is, like the above-mentioned sealing member, an elastic and flexible synthetic resin, rubber, or soft resin in order to obtain excellent sealing performance. It is preferable to use a synthetic resin or rubber, and it is particularly preferable to use silicon rubber, fluororubber, or the like, which has excellent oil resistance, durability, and heat resistance.

Furthermore, if the sealing member is fitted around the opening of the through hole on the hollow layer side, it is fitted over the entire contact surface between the cap and the spacer except the through hole. Or a part of them may be fitted, or a plurality of them may be fitted radially in a direction substantially coaxial with the drive shaft to close the gap between the drive shaft and the cap. A plurality of rings may be interposed in the axial direction of the drive shaft.

Further, in order to maintain the rigidity of the through hole and the spacer itself, the corner portion of the spacer may be provided with a corner block 12 as shown in FIG. May be included.

As the shield in the present invention, a desired material such as a slat-shaped blind, a film-shaped roller blind, or a cloth-shaped curtain can be used, and a desired coating can be applied to the surface thereof. May have been
