Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application This invention relates to a fitted window for an automobile.

b. Prior Art Generally speaking, a windshield as a fitted window is as shown in FIGS. 1 to 3.

This kind of structure is also described on page 162 of Automotive Engineering Complete Book Volume 13 (published by Sankaido).

That is, the windshield glass 2 is attached to the lube-shaped weather strip 4 around the window opening periphery P of the vehicle body.
It is installed through the seal to seal the interior and exterior of the vehicle interior and exterior. The weather strip 4 includes a groove 4a into which the glass 2 is fitted, a groove 4b into which the peripheral flange 1f is fitted, and a seal lip 4c which comes into elastic contact with the vehicle body peripheral surface 1a following the flange 1f. Further, a decorative molding 6 is fitted into the weather strip 4.

Incidentally, the sealing between the vehicle body P and the weather strip 4 is first performed by the seal lip 4c, and is also performed by a sub-rip 4d that comes into elastic contact with the rising step 1b to the flange 1f.

By the way, if we pay attention to the seal reaction force characteristics of the seal lip 4c, the weather strip 4 may be extruded around the entire circumference and formed into the same shape, or only the portion corresponding to the corner of the flange 1 may be molded separately and other parts may be formed. The general parts are extruded and joined together (although the latter is overwhelmingly the case), but the sealing reaction force of the seal lip 4c is different from the standard reaction force R ₀ at the corner part as shown in Figure 4. There is a risk that water may enter between the seal lips 4c, pass through the sub-rip 4d, and enter the passenger compartment. There are three possible solutions to this problem:

To increase the overall reaction force level of the entire seal lip 4c, To increase the seal reaction force at the corner part by increasing the thickness of the seal lip 4c at the corner part, To increase the amount of deflection of the seal lip 4c at the corner part compared to that of the general part. However, with this countermeasure, it is difficult to attach the weather strip 4 to the vehicle body P with the glass 2 attached, and the ease of attachment is extremely deteriorated. In the next countermeasure, the workability of fitting the corner portion of the weather strip 4 is extremely reduced, and installation correction work is required, which also deteriorates the workability of fitting. Moreover, the weather strip 4 is not uniform all around and its appearance quality is poor.
With this measure, it becomes difficult to match the joints between the corner portions and the general portions, resulting in poor formability of the weather strip 4.

Therefore, all of them have practical difficulties.

c. Purpose In view of the above-mentioned conventional problems, it is an object of the present invention to provide a fitted window that can improve the sealing performance of the corner portion while maintaining sufficient formability of the weather strip and mountability to the vehicle body.

d.Structure This invention extends the outer end of the molding corresponding to the corner portion, and this extended portion is inserted into the seal lip of the weather strip to the vehicle body, and the extended portion is provided with a function as a core material of the seal lip. By applying this, the seal reaction force is increased.

e Embodiment In FIGS. 5 to 8, the window glass 2 is attached to the window opening periphery P of the vehicle body through the weather strip 10, and a molding is applied to the surface exposed to the outside of the weather strip 10 along the weather strip 10. By fitting the deing 12, a fitted window is basically constructed.

This weather strip 10 comes into elastic contact with a groove 10a into which the glass 2 is fitted, a groove 10b into which the flange 1f is fitted, a seal lip 10c which comes into elastic contact with the peripheral surface 1a following the flange 1, and a rising step 1b leading to the flange 1f. It includes a sub-rip 10d and a groove 10e into which one end 12B of the main body 12A of the molding 12 is fitted.

The molding 12 is a molding main body portion 1 that is fitted into the groove portion 10e of the general portion of the weather strip 10.
2a, and a corner molding part 12b fitted to the corner part of the weather strip 10, and the other end part 12C of the main body 12A of this corner molding part 12b.
A portion 12D is extended from the outer end thereof, and this extension 12D is fitted into a groove 10f that faces the groove 10e of the weather strip 10 and extends into the seal lip 10c.

Therefore, the extension portion 12D extends into the seal lip 10c and functions as a core bar of the seal lip 10c. Moreover, this corner molding portion 12b overlaps with the end of another molding main body portion 12a to prevent the molding main body portion 12a from floating.

With this configuration, the extension portion 12D of the corner molding portion 12b provides a seal lip 1 at the corner portion.
The seal lip 10 is increased by increasing the reaction force of the seal 0c and restricting the movement of the seal lip 10c in the turning direction.
c is firmly brought into elastic contact with the peripheral surface 1a of the vehicle body P to ensure sealing between the vehicle body and the weather strip 10.

It goes without saying that the glass 2 is fitted into the weather strip 10 in advance, the weather strip 10 fitted with the glass 2 is brought to the vehicle body and fitted onto the vehicle body, and then the molding 12 is fitted onto the weather strip 10. Nor.

Therefore, the ease of attaching the weather strip 10 to the vehicle body is exactly the same as before and is good, and the moldability of the weather strip 10 can be maintained at the same moldability as before by simply forming grooves 10f at the corners. .

In addition, in the above example, in order to facilitate manufacturability,
Although the corner portion provided with the extension portion 12D of the molding 12 is formed separately from the general portion, the present invention is not limited thereto, and it goes without saying that it may be integrally molded with the general portion. For example, it is possible to integrally form the extension part 12D by providing the extension part 12D around the entire circumference of the molding 12 and then cutting only the extension part of the general part excluding the corner part.

f. Effects According to the present invention, the practical effect of improving the sealing performance of corner portions is achieved without impairing the ease of attaching the window glass to the vehicle body (that is, the attachability of the weather strip to the vehicle body) or the formability of the weather strip. do.

Moreover, when molding is done by molding the corner part separately and overlapping it with other general parts,
If installed with the corner molding facing up, it will help prevent the molding from lifting up and improve the appearance quality, as well as prevent mud build-up and improve car wash work efficiency.
