Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved double glazing for a vehicle, in which a hermetically sealed air layer is formed between two glass plates to enhance the heat insulating effect.

[0002]

2. Description of the Related Art Vehicles and other glass plates having a double structure are disclosed in Japanese Utility Model Publication Nos. 61-61218 and 63-9.
No. 8269 is disclosed. This technique is configured such that door glasses are spaced apart in the vehicle width direction and are simply arranged in parallel, and the inner and outer glass plates are individually or integrally moved up and down. Therefore, between the inner and outer glass plates. May enter the outside air and cause condensation on the inner glass plate surface due to the temperature difference between the outside air and the vehicle interior.Therefore, a mechanism or a washer that blows hot air for the defroster between the inside and outside glass plates. It is necessary to install a nozzle to prevent the glass plate from fogging and to wipe it off. Therefore, compared to a general single glass plate or laminated glass, the structure becomes extremely complicated, and the mechanism such as a washer mechanism and a large-capacity warm air blowing mechanism becomes complicated, and special devices and equipment are required. I need.

On the other hand, Japanese Examined Patent Publication No. 2-33829 is disclosed as a double glass of a type different from the double glass in which the separate glass plates are juxtaposed in parallel. In this technology, two glass plates of the same size are placed side by side,
This peripheral portion is sealed with a sealing material, and the glass plates are hermetically sealed and kept airtight to form a heat insulating air layer between the glass plates. In Japanese Utility Model Publication No. 51-26412, a glass plate of the same size and a transparent synthetic resin plate are faced apart from each other, and a spacer is provided at the peripheral end of the glass plate and the synthetic resin plate to integrate them. A double glazing is disclosed in which the space is decompressed to prevent fog. 58-47
No. 692 is disclosed, and this technology is a window glass for a ship or a railroad vehicle, in which a separate outer glass which is held by an enclosure so as to be parallel to the window glass is attached later by screwing, and is used for a defroster between the glass plates. The heat wire is interposed.

[0004]

In the above prior art, the double glass in which two glass plates are spaced apart and juxtaposed and airtightly integrated, and a heat insulating layer is formed between the inner and outer glass plates, Since it functions like one glass plate and the outside air does not enter between the glass plates, it is advantageous that the anti-fog mechanism and the washer mechanism can be configured similarly to the glass plate. By the way, when attaching such a type of double glazing to a vehicle, the inner and outer glass plates have the same shape and shape,
It is difficult to attach the glass plates themselves when attaching the glass to the vehicle body because it is a structure in which both glass plates are integrated by separating the outer edge lines of the peripheral end parts so that they coincide with each other and separating them.
Therefore, it is necessary to attach a frame material or the like to the outer periphery of the double glazing to support it on the vehicle body side. In particular, when used as a window glass that is moved up and down by a window regulator in a door glass, a frame material is inevitable, and even when used as a window glass for a fixed window, a frame material is required in combination with the vehicle body mounting part. . Therefore, the structure for attaching the double glazing to the vehicle body is complicated, the number of components is increased, and as a result of sandwiching the glass end portion by the frame, the thickness of the entire glass is increased.

Further, since the double glass is used, the plate thickness of the glass plate becomes large, and the frame portion on the vehicle body side that holds the glass peripheral portion and the frame portion of the door are compared with a conventional single glass plate or laminated glass. It becomes thicker in the thickness direction of the vehicle body and affects the width of the vehicle body and the indoor dimensions. In the door glass, the glass plate is stored inside the door so that it can be moved up and down, and the thickness of the double glass plate is not a problem because the door is thick, but the type with a sash on the top of the door and the door opening of the car body Even in the type having no sash, the door sash, the glass storage in the opening, and the thickness of the seal portion become large, which affects the indoor dimensions, which is not always preferable. In addition to the above, as a result of the thicker glass plate, the sealing member on the vehicle body side also becomes thicker and the sealing area also becomes larger, increasing the difficulty in maintaining the airtightness of the sealed portion.

[0006] The present invention has been made to solve the above problems, and the object of the present invention is to make a double glass having a heat-insulating air layer airtightly formed therein, similar to conventional single glass and laminated glass. Another object of the present invention is to provide a double glazing for a vehicle, which has a simple structure and can be reliably attached to and held in a vehicle with a sealing structure similar to the conventional one while maintaining a high sealing property.

[0007]

[Means for Solving the Problems] A means for solving the above problems comprises an outside glass plate facing the outside of a vehicle and an inside glass plate facing the inside of the vehicle, and an air layer is formed between the glass plates. It is made airtight with the outside and both glass plates are integrated, the vehicle outer glass plate is formed larger than the inner glass plate, and only the outer glass plate is inserted through the part of the outer glass plate protruding from the inner glass plate. It is a double glass for vehicles that is attached to and supported by the vehicle. Further, the outer glass plate is a double glass for a vehicle having a structure in which electrothermal printed wiring is arranged on the inner surface, and a power feeding terminal for printing the electrothermal wiring is extended to the outside of the inner glass plate. Is a double glazing for a vehicle, which is coated with an insulating synthetic resin, and an outer glass plate is adhered to a vehicle body through the insulating synthetic resin coating layer. Further, the lower part of the outer glass plate is The double glazing for vehicles is provided with a sealing mechanism that is held by an elevating mechanism and that holds a peripheral portion of an outer glass plate on the vehicle body side.

[0008]

According to the above-mentioned means, even in the case of double glazing consisting of double glazings which are spaced inward and outward, the outer glass is larger than the inner glazing and the peripheral edge of the outer glazing is inside. Since it protrudes from the peripheral edge of the glass plate, if you pay attention to the protruding part, it has the same structure as a window glass consisting of one glass plate, and the protruding part is mounted and supported on the vehicle body side, and it is also mounted on the window regulator of the door As long as it is supported, it can be attached to the opening of the vehicle body and to the window regulator as easily and surely as a general glass plate. Further, on the vehicle body side, the sealing portion may be formed by sealing the protruding portion of the outer glass plate similar to that of the single glass, so that the sealing structure may be the same as that of the single glass, and the sealing structure is complicated. However, it is simple and sufficient without increasing the size, and the sealing property is as high as the conventional one.
