Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mounting structure for a weather strip that is attached to a door opening or a trunk opening of a vehicle.

[Prior Art] As shown in FIG. 1, in order to prevent rainwater from entering the opening edge 13 of the vehicle door 2, a locking member 4 is used.
A weather strip made of an elastic material such as rubber is attached to the door 2, and the edge of the door 2 is brought into close contact with the weather strip.

That is, as shown in FIG. 2, the rocker member 4 that reinforces both side edges of the floor panel 10 is formed into a substantially box-shaped cross section by the inner panel 6 and the outer panel 5, and has a flange 16 at the upper edge of the inner panel 6.
and a flange 15 on the upper edge of the outer panel 5 are overlapped and combined, and the weather strip 7 is attached to these flanges 15, 16.

The weather strip 7 has a core material 8 made of metal or hard synthetic resin bent into a U-shaped cross section (see Figure 3).
It is integrally molded from rubber, soft synthetic resin, etc., and is provided with locking portions 7b that are strongly locked on both sides of the flanges 15 and 16, and a lip 7a that projects from one side wall. ing. As shown in FIG. 2, an outer panel 2b and an inner panel 2a
When the door 2 is closed, the edge 3 is brought into close contact with the lip 7a to prevent rainwater from entering from outside. Such a sealing device is constructed not only at the locker member 4 but also at the entire periphery of the door opening. The same applies to the trunk opening.

However, simply holding the weather strip 7 between the flanges 15 and 16 at the edge of the opening as shown in FIG. 2 is easy to assemble, but the tightening force of the weather strip 7 is weak and there is a risk of it coming off.

Therefore, as shown in FIG. 3, the clip 9, which is bent into an inverted U-shape in cross section, is engaged with the flange 16 (flange 15 is omitted) so as to firmly pinch it, and the end of the clip 9 is It has been proposed to provide a cut and raised piece 9a on the edge and engage the protruding piece 12 of the weather strip 7 with the cut and raised piece 9a, but this is because the clip 9 is attached after the car body is assembled and painted. There is a problem in that the paint film on the flange 16 is damaged and rust is likely to occur due to rainwater that blows in when the door is opened and closed.

Furthermore, as shown in FIG. 4, it has been proposed that the protruding piece 12 of the weather strip 77 is engaged with the cut-and-raised piece 17 provided integrally on the flange 16, but this There is a problem in that the inclination of the cut and raised pieces 17 varies due to errors, and the holding force of the weather strip 7 is unreliable.

[Problems to be Solved by the Invention] An object of the invention is to provide a weather strip mounting structure that has a high holding force without variation in the engaging portion.

[Means for Solving the Problems] In order to achieve the above object, the present invention has an attachment structure for a weather strip having a U-shaped cross section that is held at the edge of an opening in a vehicle body that is closed by a door, etc. A recess with a triangular cross section having a pair of inclined walls is provided along the edge of the opening. At the same time, one of the inclined walls is punched out to form a slit, and a protruding piece provided on the inner surface of the weather strip is inserted into the slit and the other inclined wall is punched out. It is formed by engaging with.

[Function] When the weather strip 7 having a U-shaped cross section is attached to the flange 16 which is the edge of the opening, the protruding piece 12 provided on the inner surface of the weather strip 7 is inserted into the slit 22.
and is engaged with the inclined wall 19.

Even if a force is applied to the weather strip 7 to pull it away from the opening edge, a strong holding force is exerted by the engagement between the protruding piece 12 and the inclined wall 19.

[Embodiments of the Invention] The present invention will be explained based on the implementation of a structure for attaching a weather strip to the edge of a door opening of a vehicle body. As shown in FIGS. 5 to 7, a depression is provided in the plate surface of the flange 16 constituting the opening edge to form an inclined wall 19 inclined from the plate surface, and
By providing a slit 22 adjacent to this recess, the protruding piece 12 of the weather strip 7 inserted into the slit 22 is made to catch on the inclined wall 19.

In order to form the inclined wall 19, as shown in FIG. 6, a recess 18 is provided in the plate surface of the flange 16, extending along the edge. The cross-sectional shape of the recess 18 is formed into a groove shape with a triangular cross section surrounded by an inclined wall 19, an inclined wall 20, and both end walls 21. As shown in FIG. 7, a slit 22 longer than the width of the inclined wall 20 is punched in the flange 16, and a portion of the inclined wall 20 and both end walls 21 are removed.

With this configuration, the inclined wall 19 is supported by both end walls 21 on the plate surface of the flange 16 at a predetermined inclination angle, and no molding errors occur as in the case of conventional cut and raised pieces. It is possible to mass-produce a constant sloped wall 19 with no variation in slope. Therefore, as shown in FIG.
2, even if a force is applied to the weather strip 7 to pull it out, the protruding piece 12 will remain on the inclined wall 1.
It doesn't bite into 9 and come off.

[Effects of the invention] As described above, the present invention is a mounting structure for a weather strip having a U-shaped cross section that is held at the edge of an opening in a vehicle body that is closed by a door, etc. A recess with a triangular cross section having a wall is provided, at the same time one of the inclined walls is punched out to form a slit, and a protruding piece provided on the inner surface of the weather strip is inserted into the slit and engaged with the other inclined wall, Since the inclined wall is formed integrally with the edge of the opening and is painted after the vehicle body is assembled, there is no problem of scratching the paint film or causing rust as with conventional clips.

Since there is no variation in the slope of the inclined wall that engages with the weather strip and there are no sharp points, the weather strip can be assembled safely and easily.

By simply inserting the protruding piece of the weather strip into the slit at the edge of the opening, the protruding piece will catch on the inclined wall and generate a high holding force against the force that would pull out the weather strip.
