Abstract

(57) [Abstract] [Purpose] To investigate the color difference and step of the draining lip at the corner of a weather strip that is fitted to a flange that stands up from the body at the periphery of the trunk opening of a car, as well as the surface texture. The purpose is to resolve the differences and improve the appearance quality of weather strips. [Configuration] Corner part (9a) of body flange (2)
A feature is that the draining lip (6) of the weather strip (1) attached to the flange (2) is pre-shaped and shaped to follow the corner portion (9a) of the flange (2).

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a weather strip attached to an automobile body flange, and in particular, By eliminating color differences and steps at the corners of the body flange, This invention relates to a weather strip for automobiles with improved appearance quality.

0002

[Conventional technology]

Among the weather strips installed on the opening and closing parts of automobiles, For weather strips installed around the trunk opening, etc., the weather strip shown in Figure 2 is usually used. As shown in Fig. 3, the trunk room (9) provided at the rear of the automobile body (5) ), the end of the body (5) is bent upward to form a body flange. (2), and attach an inverted U-shape of the weather strip (1) to the body flange (2). A shaped fitting part (3) is fitted and is integrally formed on the weather strip (1). A taper tongue-shaped draining lip (6) is brought into contact with the sealing surface (5a) of the body (5). and a hollow cylindrical seal lip ( 4), touch the inner surface of the luggage door (10) that serves as the lid of the trunk compartment (9). This is designed to provide a seal when the trunk is closed.

0003 However, when attaching the weather strip (1), it is difficult to install the weather strip (1) as shown in Figure 3. At the corner (9a) around the opening of the rank room (9), there is a weather strip. Since the weather strip (1) is bent inward, the fitting part (3) of the weather strip (1) ) The tongue-shaped draining lip (6) provided on the outer periphery cannot accommodate the difference in circumference length, and the In addition to causing cross-sectional changes as shown in (A) and (B), This will cause a seal failure.

0004 Conventionally, in order to solve the above problem, the corner part (9) of the body (5) was Only in a), as shown in FIGS. 6(A) and (B), the weather strip (1) While removing the draining lip (6), as shown in FIGS. 7(A) and (B), Separate draining lip (6') made of rubber vulcanization molded to fit the corner part (9a) was fitted and adhered to the above-mentioned cut out part.

[0005]

[Problem that the idea aims to solve]

However, while the weather strip body (1) is a rubber extrusion product, , the separate fitting adhesive draining lip (6') is a rubber vulcanized molded product, and Cut the draining lip (6) of the integrated weather strip (1) and separate that part. Since the water draining lip (6') of the body is fitted and glued, it is integrated with the weather strip. The appearance of the drain lip (6) and the separate drain lip (6') that are fitted and glued together is different from each other. There is a problem in that differences, steps, or differences in surface texture occur.

[0006] The present invention deals with the above-mentioned actual situation and finds a new structure for the draining lip. This eliminates the color difference and level difference in the draining lip at the corner of the body flange. The purpose is to improve the appearance quality of weather strips.

[0007]

[Means to solve the problem]

In other words, the features of the weather strip of the present invention that meet the above purpose are -Protrudes from the outer periphery of the fitting part that is fitted to the flange and has an inverted U-shaped cross section, when the fitting part is attached. A tapered tongue-like drainage lip that contacts the body continuous with the above flange is integrated into the In the automotive weather strip equipped with Shape the draining lip to be attached in advance to a shape that follows the corner of the flange. It is made by attaching and molding.

[0008]

[Effect]

In the weather strip of the present invention having the above configuration, the body flange The drain lip to be attached to the corner part is formed in advance in a shape that follows the corner part. Therefore, even though it is an integrated weather strip, there are no holes in the corners. It exhibits good sealing performance without getting caught when mating, and unlike conventional products. Since there are no additions, there are no differences in appearance, such as differences in level, color, and surface texture. It never occurs.

[0009]

【Example】

The automotive weather strip according to the embodiment of the present invention will be described below with further reference to the attached drawings. I will clarify.

0010 FIG. 2 is a sectional view of the weather strip according to the embodiment of the present invention. (1) is a cross section fitted to the body flange (2) of the trunk room of an automobile. An inverted U-shaped fitting part (3) and a hollow cylindrical cylinder provided on the top of the fitting part (3). The ring lip (4) protrudes from the outer periphery of the fitting part (3) and is in the installed state as shown in the figure. A seal is placed on the sealing surface (5a) of the body (5) that is continuous from the body flange (2). Each of them is integrally provided with a tapered tongue-shaped draining lip (6) that comes into contact with the roll state. . This weather strip (1) is made by extruding rubber into the fitting portion (1). 3), a seal lip (4) and a draining lip (6) are integrally provided, A core metal (7) made of lath mesh is buried inside the fitting part (3), and Inside the fitting part (3) is a holder that holds the body flange (2) from both the front and back sides. A lip (8) is provided.

[0011] As mentioned above, the weather strip (1) of this embodiment is shown in FIG. It is attached to the trunk room (9) of a car such as a car, and the trunk room The drainage lip attached to the corner part (9a) of the body flange (2) of the body flange (9) As shown in FIG. It is molded.

0012 One example of this custom molding method is weather strips (which usually have a linear shape). 1) is placed in an annular mold with the same curvature as the periphery of the luggage compartment, and heat is applied to the mold. An example of this method is to cool the rubber after adding it and shape it using the permanent deformation of the rubber. Also, this In this example, the fitting part (3) and seal lip (4) are also shaped at the same time. .

[0013] In the weather strip of the embodiment of the present invention having the above configuration, the body It is attached to the corner part (9a) of the lunge (2) and the draining lip (6) is attached to the corner part (9a). Since the weather strip is pre-formed in a shape that follows the part (9a), the weather strip is an integral part. Even though the corner part (9a) has a water-draining lip ( 6) Cross-sectional change shows good sealing performance without causing entrainment, and Unlike conventional weather stripping, there is no need to add a draining lip on the vulcanized product. As a result, there are no steps, color differences, or differences in surface skin, and the weather strip This makes it possible to improve the appearance quality of the strip.

[0014] In addition, in the embodiment, together with the draining lip (6), the fitting part (3) and the shield are The roll lip (4) is also formed in the shape of the periphery of the trunk opening. Therefore, the fitting portion (3) can be easily fitted.

[0015]

[Effect of the idea]

As explained above, the automotive weather strip of the present invention is suitable for automobile body parts. The draining lip attached to the corner of the lunge is shaped in advance to follow the corner. The weather strip is molded, and due to this structure, it is not a one-piece weather strip. However, the cross section of the draining lip changes and gets rolled up when fitting the body at the corner part. It exhibits good sealing performance without causing any Because there is no need to add a separate drain lip to the vulcanized product, there are differences in level, color, etc. There is no difference in the surface texture, and the appearance quality of the weather strip is significantly improved. This has the remarkable effect of improving performance.
