How to remove the window pane

The present invention relates to a method for removing a window pane from a window opening of a motor vehicle. Background art

As shown in FIG. 6, 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 which is a window pane.

In this specification, the upper side of the glass plate (window pane) 72 refers to the side along the roof 79 of the car 70, and the side of the glass plate 72 along the pillar 77 of the car 70. Point to the side.

FIG. 7 is a cross-sectional view taken along a line VII-VII in FIG. The upper side, which is a part of the periphery of the glass plate 72, is attached to the mounting flange 76, which is located on the periphery of the body panel 70a at the periphery of the window opening 75 of the body panel 70a. More firmly installed. The mounting flange 76 and the body panel 70a are connected by an opening side wall 75a. 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.

When the bonded portion is seen from the outside of the vehicle through the transparent glass plate 72, that is, when the adhesive 71 is seen, the appearance is reduced. In addition, when sunlight is irradiated to the bonding portion from the outside of the vehicle via the transparent glass plate 72, the adhesive 71 is deteriorated by ultraviolet rays in the sunlight.

Therefore, a dark coating material 73 is provided on the back surface (inside of the vehicle) of the peripheral portion of the glass plate 72. The adhesive 71 is interposed between the dark film material 73 and the mounting flange 76. When viewed from the outside of the vehicle, the adhesive 71 is covered by the dark film material 73. As the dark film material 73, a fired body of a black ceramic paste or the like is used. Recently, assuming recycling, it has been required to be able to easily and quickly remove the glass plate 72 for an automobile window from the body panel 70a. However, in the above-described conventional example, the glass plate 72 was firmly attached to the body panel 70a with the adhesive 71, so that it could not be easily removed. In order to remove the glass plate 72, a thread-like or rod-like cutting means is passed through the adhesive 71 shown in FIG. The adhesive 71 was cut by moving (in a direction perpendicular to the paper sheet). Such work was extremely complicated and burdensome for the worker, and the work time was long.

An object of the present invention is to provide a method of removing a window pane from which a window pane can be easily removed from a body panel of an automobile. Disclosure of the invention

In order to achieve the above-mentioned object, the present invention provides a method for manufacturing a vehicle, comprising: a window pane attached to a window opening of an automobile via an adhesive; and a bonding window of the window pane covered by a garnish from the outside of the vehicle. A window removing method for removing a pane, comprising: removing the garnish, irradiating the bonding portion with light that degrades the adhesive from outside the vehicle, and deteriorating the adhesive. A method for removing a window pane from which the pane is removed from the window opening is provided.

Here, examples of the window pane include a transparent or translucent glass plate and a resin plate. A chromatic glass plate or 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 provided with a functional coating such as strengthening treatment or heat ray reflection. Examples of light that may deteriorate the adhesive include ultraviolet light, but are not limited thereto. Not done. Ultraviolet light is preferred because it can degrade the following commonly used adhesives to the extent that the window pane can be easily removed. As a UV irradiation light source for irradiating UV light, a lamp such as a mercury lamp capable of irradiating a bright line spectrum, a xenon lamp or a lamp capable of irradiating a continuous spectrum such as various discharge tubes is used. Can be illustrated.

Examples of the adhesive include urethane-based adhesives, epoxy-based adhesives, acrylic-based adhesives, and silicone-based adhesives that can be used normally. When a glass plate is used for the window pane, or when a polycarbonate resin plate or acryl-based resin plate is used, urethane-based adhesive is used because sufficient adhesion between the window pane and the metal body panel can be obtained. Agents are preferred.

A primer for improving the adhesiveness may be interposed between the adhesive and the window pane. In this case, the window pane can be removed by inferring the primer with the light applied to the bonding portion in the present invention. Therefore, in addition to the urethane-based adhesive for bonding the window pane and the mounting flange forming the window opening, a primer used as necessary, or the primer itself is used in the present invention. It can be called an "adhesive."

Then, after deteriorating these adhesives, it is preferable to remove the window pane from the window opening so that the adhesive does not substantially remain on the window pane. Here, "substantially does not remain" means that no adhesive remains on the window pane when the window pane is removed from the window opening, and that the adhesive remains on the window pane, but is not washed with water. It means that the adhesive can be easily removed by a simple means such as cloth (including cloth impregnated with water or alcohol) or wiping with a brush.

In order to substantially prevent the adhesive from remaining on the window pane, it is preferable to use a primer and an adhesive other than the primer in bonding the window pane to the mounting flange. By deteriorating the primer by irradiating light, the adhesive can be easily prevented from substantially remaining on the window pane. By using a colored primer as a primer, light is not irradiated to the adhesive other than the primer, and only the primer can be deteriorated, so that the adhesive does not substantially remain on the window pane more easily. it can.

) Even if a part of the adhesion point is covered by the dark-colored film material Good, but when mounted on a car, all of the glued points on the window pane are covered by garnish, and the window pane is not provided with any dark coating to cover the adhesive. preferable. This allows the removed window pane to be put into the glass melting furnace as it is.

In the past, it was common sense to provide a dark-colored coating material or the like on the window pane in order to protect the adhesive portion from deteriorating the adhesive such as ultraviolet rays in the sunlight. Changed his mind and arrived at the present invention. In other words, the bonding point is covered from the outside of the vehicle using a gash that can be removed from the window pane. Actively irradiate light and the like.

No dark coating material is provided between the back surface 7 2 b of the glass plate 72 and the adhesive 71. Therefore, the bonded portion can be visually observed from the surface 72 a of the glass plate 72.

An opening side wall 75a is provided upright on the mounting flange 76 toward the outside of the vehicle. An auxiliary mounting flange 75b for attaching a garnish 11 as a decorative material is connected to the outer end of the opening side wall 75a. The auxiliary mounting flange 75b is also arranged on the vehicle inside from the surface of the pod panel 70a. The auxiliary mounting flange 75b and the body panel 70a are connected by an auxiliary side wall 75c.

The garnish 11 is attached along the periphery of the window opening 75 so as to cover the upper side and the side of the glass plate 72 from the outside of the vehicle. By forming the portion forming the window opening 75 in multiple stages as described above, the end of the garnish 11 on the side of the body panel 70a (the end on the outer peripheral side, which is called one end). The surface in) is made substantially flush with the surface of the body panel 70a to achieve a flash surface.

Between the back surface at the one end of the garnish 11 and the auxiliary mounting flange 75b, a sealing material 12a for ensuring waterproofness is interposed. In addition, mounting pins 13 as locking members are provided on the back surface at one end of the gasket 11 at predetermined intervals along the circumferential direction of the window opening 75. A through-hole is provided at a position corresponding to the mounting pin 13 of the auxiliary mounting flange 75b. The rod-shaped mounting pin 13 extends through the auxiliary mounting flange 75b. An engaging portion 13a having a predetermined shape (here, a triangular pyramid) provided at the tip of the mounting pin 13 is engaged with the back surface of the auxiliary mounting flange 75b. The end of the garnish 11 on the side of the glass plate 72 (called the inner peripheral end, the other end) is more glass than the adhesive 71 in a plan view of the glass plate 72. The plate 72 protrudes toward the center. In other words, the gasket 11 completely covers the bonded portion that is visible from the outside of the vehicle.

Note that a plurality of temporary fixing pins (not shown), which are temporary fixing locking members, are provided at predetermined intervals on the upper side and the rear side of the glass 72. The mounting flange 76 has a through hole at a position corresponding to the temporary fixing pin. The temporary fixing pin is displaced between the time the glass plate 72 is placed on the mounting flange 76 via the adhesive 71 and the time the adhesive 71 solidifies.
