Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to weather stripping.

0002

[Conventional technology]

For example, as shown in FIGS. 7 and 8, the luggage compartment (body opening) 1 of a car is a trunk. Although it is designed to be closed by the lid (vehicle body main body opening closing member) 2, A flange 8 formed on the edge 3 of the luggage compartment 1 prevents the interior of the luggage compartment 1 from being exposed to wind, rain, dust, etc. A weather strip 4 as shown in FIGS. 4 to 6 is installed to isolate the weather from ing.

0003 The weather strip 4 has a U-shaped trim part 5 that is open at the bottom and the trim part 5 has a U-shaped opening at the bottom. Hollow circular cross-sectional shape integrally formed on the outer top of the rim portion 5 and having an internal space 6 A shaped compression seal portion 7 is integrally formed on both inner side walls of the trim portion 5, and a lip 9 that protrudes into the baggage compartment 5 and clamps a flange 8 provided on the edge 3 of the luggage compartment 1; It is made up of. The compression seal part is made of hard rubber 7, and the flange 8 is made of hard rubber 7. Made of soft foam, the lip 9 is made of soft rubber and is integrally formed by extrusion molding. is formed.

In the weather strip 4 described above, when the luggage compartment 1 is closed by the trunk lid 2, the sealed surface 10 of the trunk lid 2, which descends from above in the vertical direction _L1 , as shown in FIG. It is pressed against the compression seal portion 7 of the strip 4 from directly above. For this reason, the compression seal portion 7 is compressed and deformed into a flat shape, and a wide sealing surface 11 is formed on the contact surface with the sealed surface 10 of the trunk lid 2, and the space between the trunk lid 2 and the luggage compartment 1 is Sealed in good condition.

[0005] Therefore, the luggage compartment 1 can be shielded from wind, rain, dust, etc. in the outside world.

[0006]

[Problem that the idea aims to solve]

However, in the conventional weather strip 4, when the closing locus of the trunk lid 2 comes into contact with the compressed seal portion 7, the sealed surface 10 of the trunk lid 2 descends from the diagonal direction _L2 as shown in FIG. In this case, the compression seal part 7 is not compressed into a flat shape and falls diagonally, so the flat shape collapses and the sealing surface 11 of the compression seal part 7 becomes small, making it impossible to obtain an appropriate sealing pressure and causing water to leak. There was a problem that it caused leakage.

[0007] The present invention was developed in view of the above-mentioned circumstances. The objective is to provide a weather strip that can prevent this and maintain a wide sealing surface. .

[0008]

[Means to solve the problem]

The present invention is directed to the sealed surface of the vehicle body opening closing member or the vehicle body opening closing member. An internal area that can be contacted by the sealed surface of the edge of the vehicle body opening that is closed by the closing member. A compression seal portion having a hollow cross-sectional shape with a space, and an integral part on the outer periphery of the compression seal portion. a flange connected to and provided at the edge of the vehicle body opening; or a flange connected to the vehicle body opening; A fork-shaped trim part that clamps a flange provided on the outer peripheral edge of the part closing member. In the weather stripping, from the trim part side into the internal space of the compression seal part. A first protrusion that protrudes toward the center of the interior space, and a first protrusion that protrudes toward the center of the interior space, and a protruding toward the center, and the compression seal portion is a sealed surface of the closing member; Alternatively, when it comes into contact with the sealed surface of the edge of the opening of the vehicle body and is deformed in the circumferential direction, the A weather strip characterized in that a second protrusion that can engage with the first protrusion is provided. It depends on the process.

[0009]

[Effect]

When closing the vehicle body opening with the vehicle body opening closing member, the vehicle body opening If the sealing surface of the closing member or the sealing surface of the vehicle body opening is on the weatherstrip. Even if it comes into contact with the compression seal from an oblique direction, it will not fit in the internal space of the compression seal. Because the projections engage, the compression seal part does not fall diagonally. The flat shape is always maintained in the proper shape, so the body opening and closing The space between the closing members is reliably sealed.

【Example】

Embodiments of the present invention will be described below based on the drawings.

[0011] 1 to 3 show an embodiment of the present invention.

0012 12 is a weather strip of the present invention, and the weather strip 12 is shown in FIG. The structure is completely the same except for the structure of the weather strip 4 and the compression seal part 7.

[0013] That is, the compression seal portion 13 of the weather strip 12 has an internal cavity with a hollow circular cross section. In the interior space 6, from the trim part 5 side to the center side of the interior space 6, A protrusion 14a protrudes from the side opposite to the trim portion and a protrusion 14a protrudes toward the center of the internal space 6. , and the compression seal portion 13 contacts the sealed surface 10 of the trunk lid 2; It has a protrusion 14b that can engage with the protrusion 14a when deformed in the circumferential direction. . The protrusions 14a and 14b are made of hard rubber and are integrally formed with the compression seal portion 13 by extrusion molding. It is formed.

[0014] The weather strip 12 having the compressed seal portion 13 configured as described above is, for example, Similarly to the conventional weather strip 4, it is provided on the edge 3 of the luggage compartment 1 shown in FIGS. 7 and 8. It is attached to the seal flange 8.

As shown in FIG. 2, the sealed surface 10 of the trunk lid 2 descending from above in the vertical direction L ₁ comes into pressure contact with the compressed seal portion 13 of the weather strip 12 from directly above. Therefore, the compressed seal portion 13 is compressed and deformed into a flat shape, and a wide sealing surface 11 is formed on the contact surface with the sealed surface 10 of the trunk lid 2, and the space between the trunk lid 2 and the luggage compartment 1 is A good seal is maintained.

As shown in FIG. 3, when the sealed surface 10 of the trunk lid 2 descends from the diagonal direction L ₂ and comes into contact with the compression seal portion 13 due to a change in the installation of the trunk lid 2, etc. In this case, the compression seal part 13 is not compressed into a flat shape, but at the same time as it is compressed, it deforms slightly in the circumferential direction and tries to fall down diagonally. However, at this time, the internal space 6 of the compression seal part 13 Since the provided protrusions 14a and 14b engage with each other, the compression seal portion 13 does not deform any further in the circumferential direction, and the compression seal portion 13 maintains approximately the same flat shape as in the case of FIG. 2 and is widened. A sealing surface 11 is formed and a good sealing condition is maintained.

[0017] Note that the weather strip of the present invention is not limited to the above-mentioned embodiments. However, in the embodiment of the present invention, the weather strip is installed on the luggage compartment side, which is the opening of the vehicle body. Although we have explained the case where the may be provided, and other various changes may be made within the scope of the gist of the invention. Of course, additions can be made.

[0018]

[Effect of the idea]

As explained above, according to the weather strip of the present invention, the inside of the compression seal part By providing a protrusion in the space, the sealing surface of the compression seal part is always wide. Therefore, the opening of the vehicle body and the closing member of the vehicle body are securely sealed, and the opening of the vehicle body is securely sealed. It can always shield the inside of the body from the outside world, such as wind, rain, and dust.
