BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window device for a vehicle, in particular, an automobile, which closes an opening of a vehicle body or opens and closes freely via a hinge.

[0002]

2. Description of the Related Art An automobile window device as a structure for closing an opening of a vehicle body is, for example, manufactured by a casting method.
There is one in which a plastic casing (rimming member) is integrally fixed to the periphery of a window glass plate. This cast molding method
This is a method in which a glass plate for a window is placed in a molding die, the synthetic resin for the edging member is poured around the glass plate, and the resin is cast to fix them together.

This type of vehicle window device is characterized in that it can be easily mounted from the outside of the vehicle. However, the adhesive strength between the window glass plate and the edging member is weak. Further, in the above-mentioned cast molding method, when the glass plate for a window is inserted into the molding die because the glass plate for the window is warped or the dimensional accuracy is poor due to the improvement of the design, etc. The glass plate for use is easily damaged. Therefore, there is a drawback that the yield of products is deteriorated.

According to the present invention, an endless molding is made by injection molding, and a concave holding groove for holding a glass plate for a window is provided inside thereof, and the position is set at a position of an automobile window frame to be mounted. Correspondingly, it is composed of a synthetic resin edging member having a partially different cross-sectional shape, and a window glass plate disposed inside the synthetic resin edging member, and the inner peripheral side of the synthetic resin edging member. The inner peripheral shape of the opening end formed by the opening end of the concave holding groove in is smaller than the outer peripheral shape of the window glass plate, and the peripheral edge of the window glass plate is
A window device for an automobile, characterized in that it is sandwiched in a recessed sandwiching groove of the synthetic resin edging member and integrally bonded via a hot melt adhesive layer.

The most notable point in the present invention is that the synthetic resin edging member is preformed by injection molding into an endless shape, that is, an annular frame (see FIG. 1). The cross-sectional shape differs depending on the position of the automobile window frame to be mounted (see FIGS. 3 to 6), and the inner peripheral shape of the opening end is smaller than the outer peripheral shape of the window glass plate (FIG. 7 and FIG. 8).

The concave holding groove is provided on the entire inner circumference of the synthetic resin edging member and has a U-shaped cross section (see FIG. 7). A hot-melt adhesive is applied to the inside of the concave holding groove, and the window glass plate is held therethrough. In the sandwiching, the entire recessed sandwiching groove is sandwiched so as to completely envelop the entire outer periphery of the window glass plate (see FIGS. 3 to 6 and 9).

[0008]

In the automobile window device of the present invention,
The synthetic resin edging member is endlessly formed by injection molding in advance, and the window glass plate is held in the concave holding groove of the synthetic resin edging member. Therefore, even if the window glass plate is warped due to its design, the entire endless synthetic resin edging member can be easily deformed as a whole. Therefore, the edging member made of synthetic resin can be attached to the peripheral edge of the window glass plate with good conformability and in close contact.

Further, the outer periphery of the window glass plate is mounted in a concave holding groove, and the both are integrally bonded by a hot melt adhesive layer. Therefore, the adhesion between the two is strong and has strength enough to endure as a window device of an automobile.

Further, in the conventional window device by the casting method, when the window glass plate is warped, the window glass plate may be damaged during the molding as described above. However, according to the present invention, a preformed endless synthetic resin edging member is attached to the window glass plate to form the window device.
Therefore, the window glass plate is not damaged at all. Therefore, the manufacturing yield is also excellent.

The concave holding groove is provided on the entire circumference of the synthetic resin edging member, and the inner peripheral shape of the opening end is smaller than the outer peripheral shape of the window glass plate. Therefore, the synthetic resin edging member can be easily and reliably attached to the window glass plate. Further, the synthetic resin edging member is endless. Therefore, the synthetic resin edging member once fitted does not fall off. Therefore, the mounting workability of both of them is excellent.

As described above, according to the present invention, there is provided an automobile window device in which the adhesive force between the window glass plate and the synthetic resin edging member is strong, the product yield is high, and the mounting workability of both is excellent. be able to.

a and 9b, and a temporary holding object between the synthetic resin edging member 7 and the window glass plate 4 is elastically and closely set in the space 9c formed by both a and 9b. The space 9c has substantially the same shape as the outer shape (or volume) of the window glass plate 4 in which the synthetic resin edging member 7 is temporarily sandwiched.

In the high-frequency heating / bonding step E, the silicon mold 9 is heated by the high-frequency heating device 10 under the conditions described later, and the synthetic resin edging member 7 is attached to the window glass plate 4 via the hot-melt adhesive layer 5. To glue. After that, by cooling or the like, an automobile in which the concave clamping groove 6 of the synthetic resin edging member 7 is bonded integrally from the inside of the silicon mold 9 to the peripheral edge of the window glass plate 4 via the hot melt adhesive layer 5 The window device 3 is taken out.

The application of the hot melt adhesive in the applying step B is performed by means such as brush or spray. As conditions for the heating and bonding by the high frequency heating, a heating temperature of 160 ° C., a heating time of 35 seconds and a cooling time of 100 seconds are suitable.

Next, the function and effect of this example will be described. The automobile window device 3 of this example is one in which a preformed endless synthetic resin edging member 7 is attached to a window glass plate 4. Therefore, the window glass plate 4 is not damaged at the time of manufacture, in contrast to the conventional window device manufactured by the casting method. Therefore, the product yield is excellent.

Further, a concave holding groove 6 is adhered to the outer periphery of the window glass plate 4, and a hot melt adhesive layer 5 is integrally adhered between the both. Therefore, the two are firmly bonded to each other and have sufficient strength to withstand the automobile window device 3.

The concave holding groove 6 is provided on the entire circumference of the edging member 7 made of synthetic resin, and the inner peripheral shape 6 thereof is provided.
1 is smaller than the outer peripheral shape 40 of the window glass plate 4.
