Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a weather strip interposed between a vehicle body opening and the periphery of a window glass attached to the vehicle body opening.

Examples of conventional weather strips include those shown in FIGS. 1 and 2.

That is, the weather strip 4 is interposed between the periphery of the front windshield 2 and rear windshield 3 attached to the opening of the vehicle body 1 and the edge of the vehicle body opening, and is installed between the front windshield 2 and the rear windshield 3 attached to the vehicle body. It is fixed to the opening and also seals the window glasses 2, 3 and the edge of the opening of the vehicle body, and its cross-sectional shape and mounting structure are as shown in FIG.

In other words, 4 in the figure is a weather strip.
A vehicle body fitting portion 4a that fits with a panel flange 1a provided at the opening edge of the vehicle body 1, a glass fitting portion 4b that fits with the front window glass (or rear window glass 3), and a molding 5 that fits with the vehicle body fitting portion 4a. The vehicle body fitting portion 4a has a molding fitting portion 4c that fits together with the vehicle body fitting portion 4a.
By inserting the panel flange 1a into the panel flange 1a and inserting the peripheral part of the front window glass 2 (or rear window glass 3) into the glass fitting part 4b,
The glasses 2 and 3 are attached to the vehicle body 1, and their joints are sealed.

The molding fitting groove 4c includes a groove 4d and a lip 4 protruding opposite to the opening edge of the groove 4d.
The molding is an elongated body having flanges 5a, 5a on both ends in the longitudinal direction, and a concave strip 5b on the back surface in the center, and the flanges 5a, 5a are separated by a lip 4e. , 4e, it is fitted onto the weather strip 4 and attached to the vehicle body 1 via the weather strip 4.

In order to fit the motor 5 to the weather strip 4, as shown in FIG. The lip 4e,
4e and the bottom of the groove 4d, and then insert it from one end side in the direction of arrow A and reach the other end, thereby inserting each straight part separately.

At this time, between the flanges 5a, 5a of the molding 5 and the lips 4e, 4e of the weather strip 4,
A gap is set in advance in consideration of the case where dimensional errors occur during molding, and due to this, the molding 5
When the molding 5 is attached, there is a risk that the molding 5 may be misaligned. Therefore, as shown in the figure, the weather strip is provided with a protrusion 4f that fits into the concave portion 5b provided on the back side of the molding 5. A structure has been used in which the molding 5 is positioned by fitting the protruding strip 4f into the recessed portion 5b.

However, in the case of such a structure, the opening edge in the vehicle body is usually curved with a curvature R, etc., and therefore the weather strip 4 attached to the opening edge also has a curvature R etc. It has a curved shape, and furthermore, the protrusions 4f formed on the weather strip 4 also have a similar curved shape. Therefore, when inserting the molding 5 into the weather strip 4 as shown in FIG. 4f, motor 5 which is straight
The concave portion 5b is in sliding contact. Therefore, the concave portion 5
The insertion resistance caused by the sliding contact between the molding 5 and the ridges 4f makes it difficult to insert the molding 5 into the weather strip 4. Therefore, in the case of the weather strip 4 having the ridges 4f, ni mall 5
Although it has the advantage of being able to position the molding 5, it also has the disadvantage of poor workability in inserting the molding 5.

The present invention has been made in order to solve this problem, and only the molding fitting portions located at the corners of the weather strip are provided with protrusions that fit into the grooves formed on the back side of the molding. The object of the present invention is to provide a weather strip for an automobile which can improve the insertion workability and also has a sufficient molding positioning function.

The configuration of the present invention will be described below according to an embodiment shown in FIG. 4 and subsequent figures. In Figure 4, 1
4 is a weather strip with straight portions 14a, 1
As is well known, the straight parts 14a and 14b are joined to the ends of the straight parts 14a and 14b by extrusion molding, and the corner part 14c is joined to the ends of the straight parts 14a and 14b by molding. and mold it. 15 is a convex strip, and the corner portion 14
The groove 14d is provided at the bottom of the groove 14d, and its cross-sectional shape is as shown in FIG.
It has a shape that can be inserted into the recessed part 5b formed on the back side of the motor 5 attached to the groove part 14d, and its planar shape is such that it can be inserted into the straight part 14a side as shown in FIG. It is approximately L-shaped, consisting of an insertion part 15a inserted into the concave part of the molding to be fitted, and an insertion part 15b inserted into the concave part of the molding fitted to the straight part 14b side. Sometimes it is molded in one piece. Note that lip 14e, 1
4e, the vehicle body fitting part 14f, and the structure of the glass fitting part 14g are the same as those of the conventional example.

In this embodiment having the above configuration, the weather strip 14 has the front window glass 2 (or rear window glass 3) as shown in FIG. The panel flange 1a of the vehicle body is fitted into the joining portion 14g, and is interposed between the vehicle body opening edge and the peripheral edge of the front window 2 (or rear window glass 3), and both longitudinal edges are provided between the lips 14e and 14e. A molding 5 having flanges 5a, 5a and a concave portion 5b in the center back surface is inserted from one end side of each of the straight portions 14a, 14b.

At this time, since the straight portions 14a and 14b are not provided with the protruding strip 15, the insertion end of the molding 5 does not come into sliding contact with the protruding strip 15, and furthermore, a gap is provided in consideration of molding errors between both members. This allows for smooth insertion work (Figure 6).
Therefore, the insertion work efficiency can be improved.

When the molding 5 reaches the corner portion 14c as it is inserted, since the corner portion 14c is provided with the protrusion 15, the straight portion 14a
The molding 5 fitted on the side is the insertion part 15 of the protrusion 15
The molding 5 fitted on the straight part 14b side is fitted into the fitting part 15b, and the molding 5 is positioned at the end.

Of course, since the protrusions 15 are provided at each corner, the protrusions provided at the corners of the molding 5 will fit even in the uninserted part, so that the protrusions 15 will fit at both ends. Positioning is performed by the protruding strips 15, and sufficient positional regulation is achieved.

As explained above, the present invention provides a weather strip that is interposed between a vehicle body opening and the periphery of a window glass that is attached to the vehicle body opening, and that has a molding fitting part. In the case where a molding is inserted and fitted into the weather strip, only the molding fitting part located at the corner part of the weather strip is provided with a protrusion that fits into a concave part formed on the back side of the molding. Since we have provided a weather strip for automobiles, first of all, when inserting the molding into the molding fitting part, the molding insertion end comes into contact with the convex strip that is conventionally provided in the molding fitting part. However, the insertion operation can be performed smoothly without being prevented by the frictional resistance=insertion resistance, and thus the operation efficiency can be improved. Furthermore, after the insertion work is completed, the molding is positioned at both ends by inserting the concave portions into the convex strips provided at the corners of the weatherstrip. Even if a gap is provided between the mounting part and the molding in consideration of errors during molding, the position can be reliably regulated without misalignment within the gap.
