Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a bonding structure for various members to a glass plate.

(Prior Art) In the case of automobile window glasses, the glass plate is attached to the body, and various members such as pins, retainers, guide rollers, etc. are attached to the glass plate in order to connect it to a lifting device.

In order to attach various members to a glass plate, holes are generally formed in the glass plate and the members are inserted into the holes. However, in the case of using the above-mentioned means, the attachment work must be carried out with great care so as not to damage the glass plate, and the strength of the attachment location is also weakened.

Therefore, in recent years, members have been bonded to glass plates using two-component structural adhesives, particularly two-component structural adhesives, which have extremely strong adhesive strength.

(Problem that the invention aims to solve) If components are bonded together using the above-mentioned structural adhesive, a product with excellent strength can be obtained, but the adhesive force of the adhesive exerts its initial strength. It takes several hours to complete the process, and during this time there is a risk that the component may become misaligned, so the component must be held with clips or the like for a long period of time. Also, use adhesive
If heated to 40° to 80°C, initial strength can be achieved in a short period of time (several minutes), but the member still needs to be held for a predetermined period of time, and a heating device is also required.

(Means for solving the problem) In order to solve the above problem, the present invention divides the adhesive surface of the member to be adhered to the glass plate into a main adhesive surface and a sub-adhesive surface, and the main adhesive surface and the glass plate are different from each other, for example. A two-component mixed structural adhesive was used, and the sub-adhesive and the glass plate were bonded together using an instant adhesive.

(Example) An example of the present invention will be described below based on the accompanying drawings.

Fig. 1 is a front view of a motorcycle window glass to which the adhesive structure according to the present invention is applied.
are spaced apart and glued.

As shown in FIG. 2A, which is a side view, and FIG. 2B, which is a bottom view, the pin 2 has a flange portion 4 integrally formed on the bottom of the pin body 3, and an outward protruding piece 5 on the flange portion 4. , 5. The bottom surface of the flange portion 4 is used as a main adhesive surface 6, and the bottom surface of the protruding piece 5 is used as a secondary adhesive surface 7.

FIG. 3A is a side view of another embodiment, and FIG. 3B is a bottom view of the same embodiment.
A circular flange portion 14 is formed at the bottom of the main body 3 of the pin 2, and the bottom surface of the flange portion 14 is divided by a groove 15 into an inner main bonding surface 16 and an outer secondary bonding surface 17.

Further, FIGS. 4 and 5 show a guide roller 20 as a member, and the guide roller 20 shown in FIGS. Projection piece 2
3 are integrally molded, and the bottom surface of the flange portion 22 is used as a main adhesive surface 24, and the bottom surface of the protruding piece 23 is used as a secondary adhesive surface 25.

Further, the guide roller 20 shown in FIGS. 5A and 5B has a rectangular flange portion 22 formed at the bottom of the main body 21.
The bottom surface is divided by grooves 26, 26 in the width direction,
The inner surface defined by these grooves 26, 26 is a main adhesive surface 27, and the outer surface is a sub-adhesive surface 28.

In order to adhere the above pins 2 or guide rollers 20 to the glass plate 1, the main adhesive surfaces 6, 16, 24, 2
A two-component mixed structural adhesive such as epoxy, urethane, acrylic, or silicone is discharged onto 7 using a quantitative dispensing device, and then applied uniformly with a spatula, etc., and the secondary adhesive surfaces 7, 17, 25 and 28 are coated with a cyanoacrylate instant adhesive in the same manner as described above.

Next, the pin 2 or the bottom surface of the guide roller 20 is pressed against the glass plate 1. Then, the pin 2 or the guide roller 20 is instantly fixed to the glass plate 1 by the instant adhesive applied to the sub-adhesion surface, and no displacement occurs. Further, the two-component mixed structural adhesive applied to the main adhesive surface gradually hardens while the pin 2 or guide roller 20 is fixed to the glass plate 1.

In the embodiment, pins and guide rollers are shown as members to be bonded to the glass plate, but it is needless to say that the members are not limited thereto.

(Effects of the invention) As explained above, according to the invention, the adhesive surface of the member to be adhered to the glass plate is divided into the main adhesive surface and the sub-adhesive surface, and the main adhesive surface is divided into two parts with extremely high adhesive strength. By using a mixed-type structural adhesive, the sub-adhesive surface is bonded to the glass plate using an instant adhesive that instantly exerts adhesive force, so it will not work until the structural adhesive develops its initial strength. Components can be held together with instant adhesive, or with conventional clips, etc.
It eliminates the need to prepare a heating device, and exhibits many effects such as sufficient adhesive strength after a predetermined period of time has elapsed.
