DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary fixing structure of an adhesive type window glass applied to a vehicle such as an automobile.

[0002]

2. Description of the Related Art For example, a window glass which does not open and close like a windshield or a rear glass of an automobile is usually fixed to a flange of an opening provided in a vehicle body by using an adhesive. Such an adhesive type window glass has male and female dual lock fasteners (generally registered trademark of Velcro) corresponding to both the window glass and the vehicle body for positioning with respect to the vehicle body at the time of bonding. In general, the two are engaged and temporarily fixed by engaging them.

However, since the dual lock fastener can be engaged even if the relative positions of the male and female are slightly shifted,
There is a drawback that positioning in the vertical and horizontal directions cannot be performed with high accuracy, and therefore, an assembling operation using a jig must be performed.

As a solution to the above-mentioned drawbacks of the dual lock fastener, a clip technique disclosed in Japanese Utility Model Laid-Open No. 5-32043 has been proposed.

[0005]

However, in the above-mentioned clip type, the abutting piece and the locking claw restrict the position of the window glass up and down, left and right, and front and rear (glass front direction). Therefore, when curing the adhesive interposed between the glass surface and the vehicle body, there is a disadvantage that the displacement of the window glass toward the vehicle body cannot be tolerated, so that it is difficult to sufficiently increase the adhesive force. .

Further, in such a clip system, the contact piece is pressed against the vehicle body during the operation of curing the adhesive for pressing the window glass against the vehicle body. It has a disadvantage that it also acts on glass.

Therefore, an object of the present invention is to position a window glass in three directions of up and down, right and left, and back and forth with respect to a vehicle body, and to apply a predetermined amount of compressive force to the adhesive force when curing the adhesive. SUMMARY OF THE INVENTION It is an object of the present invention to provide an adhesive-type window glass temporary fixing structure that can be kept.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and has a structure in which a temporary fixing structure for an adhesive type window glass is provided with an engaging hole provided in a vehicle body to which the window glass is bonded. A locking projection and two hollow elastic projections arranged in series on both sides of the locking projection from the back surface of the bonding surface of the substrate bonded to the window glass, and are integrally formed of synthetic resin. A fastener having a stopper in which the hollow elastic protruding piece regulates a stroke inside, and a locking projection of the fastener bonded to the window glass is provided in an engaging hole of the vehicle body. It is characterized in that it is configured to be fitted and to maintain a locked state between the locking projection and the engagement hole by a reaction of the elastic projection.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 6 is a perspective view showing an outline of the appearance of a passenger car. A window glass 2 is fixed to an opening of a vehicle body 1 by bonding. When the window glass 2 is bonded, the positioning to the vehicle body 1 and the temporary fixing are performed by using the fastener 3 previously bonded to the window glass 2 side.

FIG. 1 shows a cross section taken along line CC of FIG.
(A) is a state before the window glass 2 is temporarily fixed, and (b) is a state where the window glass 2 is temporarily fixed. The fastener 3 used in the present invention is an integrally molded part of a synthetic resin as shown in FIGS. 3 and 4, and a locking projection 5 and an elastic projection 6 project from one surface of the substrate 4. Have been. in this case,
In the present invention, the two elastic projections 6 formed in a hollow shape are arranged in series on both sides of the locking projection 5, and
Stopper 6 for regulating stroke is provided in the hollow portion of
a is provided. The fastener 3 having such a shape and configuration is easy to form and manage components, and can evenly apply the pressing force of the elastic projection 6 to the locking projection 5 to temporarily hold the window glass 2. It has the advantage that the posture can be stabilized. The synthetic resin for integrally molding the fastener 3 is preferably one having elasticity, such as polypropylene (PP) or vinyl chloride (PVC).
Etc. are suitable.

Also, the locking projection 5 of the fastener 3 described above.
Is inserted into an engagement hole 7 provided at a predetermined position of the vehicle body 1 when the window glass 2 is temporarily fixed, whereby positioning between the window glass 2 and the vehicle body 1 is performed. The locking claw 5a provided on one surface serves as a stopper to keep the fitted state. The elastic protruding piece 6 in a natural state that is not subjected to a load is formed so that the height h protruding from the surface of the substrate 4 is higher than the position of the locking claw 5a.

As shown in FIG. 3, the fastener 3 having the above-described configuration has a substrate 4 on which a locking projection 5 and an elastic projection 6 are projected.
For example, a double-sided tape 8 is adhered to the back surface of the window glass 2 for adhesion to the window glass 2, the release sheet 9 is peeled off at the time of use, and the fastener 3 is adhered to a predetermined position of the window glass 2. As shown in FIG. 2 (b), when the locking projection 5 is aligned with the engaging hole 7 and pushed into the vehicle body 1, the locking claw 5a is turned into an arrow as shown in FIG. It elastically deforms in the direction and passes through the engagement hole 7. As a result, the locking claw 5a is locked by the engaging hole 7 of the vehicle body 1 to prevent it from falling off, and the elastic protruding piece 6 is compressed and bent between the vehicle body 1 and the window glass 2. (See FIG. 1B and FIG. 2A). In FIG. 2A, reference numeral 10 denotes a windshield molding,
Reference numeral 1 denotes an adhesive.

Therefore, at least two combinations of the fastener 3 and the engagement hole 7 are provided, and when the pushing force of the window glass 2 is released after the above operation, the reaction of the compressed elastic projection 6 causes the engagement projection 5 The window glass 2 is accurately positioned with respect to the vehicle body 1 vertically and horizontally and back and forth (in the direction of the glass surface). Then, by continuously applying a predetermined pressure using a means for pressing the window glass 2 from the outside of the vehicle body 1 from such a temporarily fixed state, the uncured adhesive 11 is cured after a predetermined time has elapsed, and the window glass 2 Is completed on the vehicle body 1. In addition, since the elastic protruding piece 6 is allowed to bend when the window glass 2 is hardened by bonding, the bonding strength can be increased by applying a uniform pressing force. Can elastically support the window glass 2 with respect to the vehicle body 1,
This is effective in reducing the body vibration input to the window glass 2.

The elastic projection 6 of the fastener 3 can be formed at a low cost and with high precision.
And a hollow one that is integrated. For this reason, the stopper 6a for regulating the stroke of the elastic protruding piece 6 can also be easily formed integrally with the inside of the hollow, and the provision of the stopper 6a causes an overstroke in the pushing amount of the window glass 2 into the vehicle body 1. Can be prevented,
Therefore, there is no possibility that the adhesive thickness of the adhesive 11 becomes thin and deviates from the set range.

[0016]

According to the present invention described above, the locking projection of the fastener and the elastic projection are projected from the substrate, and the engagement between the locking projection and the engaging hole of the vehicle body is caused by the reaction of the elastic projection. The stationary state is maintained, and the positioning of the window glass is finally performed by the locking projection. Since the locking projection is not elastically deformed, the positioning of the window glass does not change when the window glass is mounted. Therefore, it is possible to easily restrain the vertical and horizontal positioning of the window glass with respect to the vehicle body, and to temporarily fix the window glass in a stable and accurate manner.

Further, when mounting the glass, only the step of bonding the substrate formed integrally with the locking projection and the elastic projection to the glass is required, so that the operation is simplified.

Further, since the locking projection and the elastic projection are integrally formed of a synthetic resin together with the substrate, and the elastic projection is hollow, the elastic projection has sufficient rigidity while having sufficient rigidity. Elasticity can be ensured. In addition, since the elastic projection has a stopper inside, it is possible to prevent an overstroke from being caused in the amount of pushing the window glass. In addition, since the synthetic resin is integrally molded, not only is it advantageous in improving accuracy, but also it can be manufactured at low cost.

In addition, at the time of the adhesive curing operation, a predetermined amount of compressive force can be applied to the adhesive force by the reaction force of the elastic projection, so that the adhesive bonding state can be sufficiently improved.
