DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window plate mounting structure for easily removing a window plate from a window opening of an automobile.

[0002]

2. Description of the Related Art As shown in FIG. 3, a plurality of window openings 75 are formed in a body panel 70a of an automobile 70. The window openings 75 are closed by a transparent glass plate 72 serving as a window plate. In this specification, the upper side of the glass plate (plate material for window) 72 is the roof 7 of the automobile 70.
9 and the side of the glass plate 72 is the
Side along the pillar 77 or the like.

FIG. 4 is a sectional view taken along the line IV-IV in FIG. An upper side, which is a part of a peripheral portion of the glass plate 72, has a mounting flange 76 disposed on the inner side of the surface of the body panel 70a at the periphery of the window opening 75 of the body panel 70a.
Are firmly attached by an adhesive 71. The mounting flange 76 and the body panel 70a are connected to the opening side wall 75.
a. The mounting flange 76 extends along the periphery of the window opening 75 of the body panel 70a. The upper and side edges of the glass plate 72 are adhered to the mounting flange 76.

[0004] When the bonded portion is visible from the outside of the vehicle through the transparent glass plate 72, that is, when the adhesive 71 or the like is visible, the appearance is deteriorated. In addition, when solar radiation is applied to the bonding portion from outside the vehicle via the transparent glass plate 72, the adhesive 71 is deteriorated by ultraviolet rays in the solar radiation. In view of this, a dark coating layer 73 is provided on the rear surface (inside of the vehicle) of the peripheral portion of the glass plate 72. The adhesive 71 is interposed between the dark film layer 73 and the mounting flange 76. When viewed from the outside of the vehicle, the adhesive 71 is covered by the dark film layer 73. As the dark coating layer 73, a black coating layer obtained by firing a ceramic paste is used.

[0005]

Recently, assuming recycling, a glass plate 72 for an automobile window is mounted on a body panel 70.
There is a need for easy and quick removal from a. However, in the conventional example described above, the glass plate 7
2 was firmly attached to the body panel 70a with the adhesive 71, and thus could not be easily removed.
In order to remove the glass plate 72, the adhesive 7 shown in FIG.
1, a thread-shaped or rod-shaped cutting means is passed through in the left-right direction in the figure, and the cutting means is moved along the periphery of the window opening 75 (in a direction perpendicular to the plane of the paper in the figure). The adhesive 71 was cut. Such work is extremely complicated and burdens the operator, and the work time is long. Furthermore, even if the adhesive 71 is cut and the glass plate 72 is removed, recycling the glass plate 72 has the following problem. That is, the glass plate 72 is provided with the dark color coating layer 73 obtained by firing the ceramic paste. Since the dark film layer 73 contains various substances, it is preferable to put the glass plate 72 into a glass melting furnace for recycling after removing the dark film layer 73. Therefore, when such a dark-colored film layer 73 is provided on the glass plate 72, the recycling operation of the glass plate 72 becomes complicated. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a window plate mounting structure that allows a window plate to be easily removed from a body panel of an automobile.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention relates to a window plate having an organic paint layer formed on at least a part of a peripheral portion thereof. The window plate mounting structure attached to the portion, wherein the organic paint layer protects the adhesive from solar light without being deteriorated by solar light, and is formed from a material that is deteriorated by light of a specific wavelength. Wherein the adhesive is hidden from the outside of the vehicle by the organic paint layer.

Here, examples of the window plate material include a transparent or translucent glass plate and a resin plate. A chromatic glass plate or a resin plate may be used as long as it has sufficient transparency. Examples of the glass plate include a single glass plate and a laminated glass. Further, the glass plate may be subjected to a strengthening treatment or a functional coating treatment such as a heat ray reflection film.

As a specific wavelength of light that deteriorates the organic paint layer, light having a shorter wavelength than the ultraviolet light included in the solar radiation can be exemplified. On the other hand, since a normal glass plate hardly transmits light having a wavelength of 300 nm or less, light having a wavelength of 300 nm or less can be exemplified as light having a specific wavelength that deteriorates the organic paint layer. Further, when a glass plate having an ultraviolet absorbing performance is used, this glass plate is 340n.
Since almost no ultraviolet light having a wavelength of 340 nm or less is transmitted, light having a wavelength of 340 nm or less can be exemplified as light that deteriorates the organic paint layer. Illumination means for irradiating light of these wavelengths include a lamp capable of irradiating a bright line spectrum such as a mercury lamp, a xenon lamp, and a lamp capable of irradiating a continuous spectrum such as various discharge tubes. Further, the wavelength 248
KrF excimer laser capable of irradiating light of nm, wavelength 19
ArF excimer laser capable of irradiating 3 nm light, wavelength 1
It is preferable to use a far ultraviolet ray irradiating means such as an F ₂ excimer laser capable of irradiating 57 nm light from the viewpoint of a preferable material form of the organic paint layer in the present invention described below.

As a material for the organic paint layer, for example, 340
Those that are degraded by light having a sharp peak at a specific wavelength of less than nm can be used. Examples of such a material include a commonly used pigment-added colored organic paint such as an acrylic or epoxy paint to which an ultraviolet absorber is added. Examples of the ultraviolet absorber include various ultraviolet absorbers such as benzophenone, benzotriazole, and cyanoacrylate. These ultraviolet absorbers are used in a range from about 270 to 280 nm to 370 to 38.
It has an effective absorption wavelength performance up to about 0 nm. Therefore, the organic paint layer formed from the organic paint material to which these ultraviolet absorbers are added can absorb the ultraviolet rays of the solar light passing through the glass plate by the ultraviolet absorber, and the organic paint by such ultraviolet rays can be absorbed. The layer can be prevented from deteriorating, and the adhesive can be shielded from sunlight. Since the effective absorption wavelength performance of these ultraviolet absorbers is from about 270 nm to 380 nm, the window plate material is deteriorated by the light from the above-mentioned far ultraviolet irradiation means to deteriorate the organic paint layer. Thereby, it can be removed from the window opening. The organic paint layer may be provided on the vehicle interior side surface of the window plate material, may be provided on the vehicle exterior side surface, or may be provided on both the vehicle interior side surface and the vehicle exterior side surface. When a glass plate is used as the window plate, it is preferable to provide an organic paint layer on the inside surface of the glass plate because the glass plate does not transmit light having a wavelength of 300 nm or less out of sunlight. The organic paint layer may be covered with a garnish on the outside of the window plate.

Examples of the adhesive include urethane-based adhesives, epoxy-based adhesives, acrylic-based adhesives, silicone-based adhesives and the like which can be used usually. When a glass plate is used for the window plate, or when a polycarbonate resin plate or an acrylic resin plate is used, the adhesiveness between the window plate (the organic paint layer provided on the) and the metal body panel is reduced. A urethane-based adhesive is preferred in that it can be obtained sufficiently.

Conventionally, it is common sense to integrate a dark-colored film layer obtained by firing a ceramic paste on a window plate material in order to protect the bonding portion from deteriorating the adhesive such as ultraviolet rays in sunlight. However, the present inventors have changed their ideas and arrived at the present invention. That is, the adhesive is protected from sunlight without being deteriorated by the sunlight, and an organic paint layer that is deteriorated by light of a specific wavelength (degraded light) is provided on the window plate so as to cover the adhesive. In addition, when the window plate is removed from the body panel, the deterioration light is applied to the organic paint layer. ADVANTAGE OF THE INVENTION According to the window-plate mounting structure of this invention, a window-plate can be removed from an automobile body panel very easily and in a short time. Further, the structure does not become complicated as compared with the conventional window plate mounting structure.

Embodiments of the present invention will be described below in detail with reference to the drawings. In the embodiment described below, members having the same configuration and operation as those already described are denoted by the same reference numerals or corresponding reference numerals in the drawings to simplify or omit the description.

The window plate mounting structure 10 shown in FIG. 1 can be applied to, for example, a front window and a rear window of an automobile 70 as shown in FIG. An organic paint layer 11 is provided on the rear surface (inside of the vehicle) of the upper side and the side of the glass plate 72 as the window plate. An adhesive (here, urethane sealant) 71 is provided on the organic paint layer 11. The adhesive 71 includes a mounting flange 76 disposed on the inner side of the surface of the body panel 70 a at the periphery of the window opening 75 of the body panel 70 a, and the glass plate 7.
2 and the organic coating layer 11 provided on the second coating layer 2. Here, a primer (not shown) is provided between the organic paint layer 11 and the adhesive 71. Adhesive 71
Is concealed from the outside of the vehicle by the organic paint layer 11, and is not exposed to the sunlight irradiated from the outside of the glass plate 72.

When the glass plate 72 is detached from the window plate mounting structure 10, as shown in FIG. 2, the degraded light irradiating means 20 for generating light for deteriorating the organic paint layer 11 is provided on the outside of the glass plate 72. To place. FIG. 2 shows a state in which the deteriorating light irradiating means 20 is disposed close to the periphery of the glass plate 72 on the vehicle outside. Then, the glass plate 72 is irradiated with the deterioration light L from the deterioration light irradiation means 20. As the deterioration light irradiation means 20, it is preferable to use the above-mentioned far ultraviolet irradiation means. Therefore, light having a wavelength of 250 nm or less is preferable as the deteriorated light L.

The degraded light L passes through the transparent glass plate 72 and reaches the organic paint layer 11. The organic paint layer 11 is deteriorated by the deterioration light L. Then, as the organic paint layer 11 deteriorates, the adhesion at the interface between the glass plate 72 and the organic paint layer 11 decreases. Thus, the glass plate 72
Only the body panel 70a is removed. When the organic paint layer 11 is deteriorated and the function of the organic paint layer 11 as a protective film is destroyed and the degraded light L shines on the adhesive 71, the adhesive 71 also deteriorates. If the adhesive 71 is appropriately deteriorated, it becomes easier to remove the glass plate 72 from the body panel 70a.

According to the above-described window plate mounting structure 10, the glass plate 72 can be removed from the body panel 70a of the automobile very easily and in a short time. Also,
The structure is not complicated as compared with the conventional window plate mounting structure.

The present invention is not limited to the above-described embodiment, but can be appropriately modified and improved.
For example, an adhesive may be provided on the organic paint layer provided on the window plate, and a molding may be interposed between the adhesive and the mounting flange 76. In this case, when deteriorating light is applied to the bonded portion from the outside of the vehicle to remove the window plate, the adhesion of the interface between the glass plate and the organic paint layer is reduced due to deterioration of the organic paint layer, and the window plate is removed. Can be removed from the mall.

[0018]

As described above, according to the present invention,
The window plate can be very easily and quickly removed from the body panel of the automobile. Further, the structure does not become complicated as compared with the conventional window plate mounting structure. Further, when a glass plate is used as a window plate, the glass plate does not need to be provided with a dark-colored film layer in which a ceramic paste is fired, and the organic paint layer remaining on the glass plate is deteriorated and the resin component is decomposed. As a result, these organic paint layers can be easily removed from the glass plate. If the glass sheet from which the residue is removed is put into a glass melting furnace for recycling, recycling of the glass sheet can be easily achieved.
