【Example】

 Embodiments of the present invention will be described below with reference to the drawings, and the above-mentioned conventional drawbacks will be more specifically described with reference to the drawings.

FIG. 1 is a perspective view showing a truck which is an example of an automobile, and FIG. 2 is an enlarged sectional view taken along line II-II of FIG. In these drawings, reference numeral 1 denotes a roof which constitutes an upper part of the vehicle body 2, 3 denotes a front pillar, and 4 denotes a front panel, respectively. Is fixed. A door 6 is pivotally supported on the side portion of the vehicle body 2 so as to be openable and closable, and as shown in the figure, the door 6 is closed to close a door opening 7 (FIG. 2) of the vehicle body 2.

The door 6 has a door body portion 9 and a window frame portion 10, which are composed of an outer panel 11 located outside the vehicle and an inner panel 12 located inside the vehicle, as shown in FIG. Both panels 11 and 12 are integrated by a hemming process at their peripheral portions. A channel-shaped retainer 13 is fixed to the parts of both panels 11 and 12 along the window opening defined by the window frame 10, and a glass run 14 is fitted to this, and is supported by the door body 9 so as to be able to move up and down. When the opened window glass 15 moves up and down, the edge of the window glass 15 slides on the glass run 14.

The roof 1 has a roof side rail 16 extending in the front-rear direction on a side portion of the vehicle body 1 and a roof panel 17, and the roof side rail 16 includes an outer panel 16a on the outer side of the vehicle and an inner panel 16b on the inner side of the vehicle. The upper mating flange part and the side edge part of the roof panel 17 are integrally fixed.

A lower mating flange portion of the roof side rail 16 is also integrally fixed, and a main weather strip 18 made of an elastic material is fitted therein. The main weather strip 18 extends along the door opening 7 (see also FIG. 4), and when the door 6 is closed as shown in the figure, it is elastically deformed by being pushed by the door 6 as shown in FIG. Retains sex.

When it rains or snows, rainwater on the roof 1 travels along the surface of the roof 1 and flows to the door 6 as indicated by an arrow A in FIG. At this time, since there is a gap G between the closed door 6 and the vehicle body 2, rainwater enters this gap and stays in the area near the main weather strip 18 as indicated by the symbol B to open the door 6. If you do so, the remaining rainwater may fall downward and fall on the occupants.

In order to prevent such a problem, a weather strip 19 according to the present invention is provided in addition to the main weather strip 18. The weather strip 19 is located outside the main weather strip 18 and extends along the door opening 7 of the vehicle body 2 from the roof 1 of the vehicle body 2 to the front pillar 3 as shown in FIG. The weather strip 19 is also made of an elastic material such as rubber or soft synthetic resin.

The weather strip 19 is, as shown in FIG. 2, a base portion 20 fixed to the vehicle body 2 by an adhesive tape, a clip or the like, and a projection from the base portion 20 toward the vehicle inner surface 6 a of the closed door 6, It has a lip 21 that comes into pressure contact with the inner side surface of the vehicle, and is formed in a gutter shape with the upper portion opened by the base portion 20 and the lip 21. Therefore, the rainwater W flowing along the surface of the roof 1 as shown in FIG. 2 is received by the gutter-shaped weather strip 19, and then extends along the pillar 3 as shown by an arrow C in FIG. The strip 19 is guided to flow down and discharged outside the vehicle body.

As described above, the rainwater transmitted through the roof 1 is received by the weather strip 19 and discharged to the outside of the vehicle body. Therefore, it is possible to prevent the rainwater from remaining in the gap G between the door 6 and the vehicle body 2. Therefore, when the passenger opens the door 6, it is possible to prevent the rainwater from splashing on the passenger. Further, when the door 6 is opened, the weather strip 19 becomes free due to its elasticity as shown by the chain line in FIG. 2, and receives the rainwater W.

By the way, although the weather strip 19 extends from the roof 1 to the front pillar 3, the conventional weather strip has the cross-sectional shape shown in FIG. 2 over its entire length. That is, as shown in FIG. 6, the portion of the weather strip 19 extending along the pillar 3 is also formed in a gutter shape with one side open, and rainwater flows down in the groove of the gutter portion. is there. If the groove has such a groove, as described above, the external air flow is disturbed in the region near the groove of the weather strip 19 as shown by the arrow in FIG. However, there was a possibility that wind noise would be generated.

In order to prevent such a problem, the portion of the weather strip 19 extending along the pillar 3 has a tubular closed cross-sectional shape as shown in FIG. It can be considered as a road. In this way, when the door 6 is closed, the gap between the door 6 and the pillar 3 can be filled with the weather strip 19, so that the concave groove shown in FIG. It is possible to prevent turbulence of the airflow during driving and prevent wind noise.

However, when the weather strip 19 is formed in a hollow cylindrical shape as shown in FIG. 7, its elastic repulsive force is increased and air is easily trapped in the passenger compartment when the door 6 is closed. Therefore, a large operation force is required when the door 6 is closed, and its operability is reduced. Moreover, when foreign matter enters the hollow portion inside or water inside is frozen, it cannot be removed, and the operability of the door 6 may further deteriorate.

The present invention provides a weather strip that eliminates such problems.

FIG. 3 is a front view showing the weather strip 19 shown in FIG. 1 and FIG. 2 taken out. Here, the weather strip 19 flows through the roof 1 of the vehicle body 2. The former part is called the first strip part, and the latter part is referred to as the first strip part, and the latter part is designated as the latter part. It is referred to as a second strip portion, and is denoted by reference numeral 19b.

Since the first strip portion 19a is a portion for receiving rainwater from the roof 1, it usually coincides with a portion extending forward and backward along the roof 1, and the second strip portion 19b guides rainwater downward. Since it is a portion, it usually coincides with a portion extending along the front pillar 3.

FIG. 2 shows the cross-sectional shape of the first strip portion 19a of the weather strip 19, but this cross-sectional shape is as described above. That is, the first strip portion 19a protrudes from the base portion 20 fixed to the outer panel 16a of the roof side rail 16 forming the vehicle body, and from the base portion 20 toward the vehicle interior side surface 6a of the closed door 6, It comprises a lip 21 elastically pressed against the inner surface of the vehicle, and the lip 21 and the base portion 20 are formed in a gutter shape so as to receive the rainwater transmitted through the roof 1 as described above.

On the other hand, as shown in FIG. 4, the second strip portion 19b is closed from the base portion 20 fixed to the front pillar 3 that constitutes the vehicle body 2 and the respective widthwise end portions of the base portion 20. The door 6 is formed of a pair of lips 21 and 22 protruding toward the vehicle interior side surface 6a and elastically pressed against the vehicle interior surface 6a. That is, in the second strip portion 19b, in addition to the base portion 20 and the lip 21 of the first strip portion 19a, another lip 22 is provided. In the example shown in FIG. 4, the lip 22 is connected to the base portion 20 via a connecting portion 23 that is in contact with the front pillar 3. Incidentally, the free state of these rips when no external force is applied to both rips 21, 22 is shown by a chain line in FIG.

As shown in FIG. 4, when the door 6 is closed, the closed cross section is closed by the pair of lips 21 and 22 of the second strip portion 19 b, the base portion 20 thereof, and the vehicle interior side surface 6 a of the door 6. -Shaped flow path 24 is defined. Therefore, as described above, the rainwater flowing through the roof 1 and received by the first strip portion 19a flows out of the first strip portion 19a, and then is guided to the flow path 24 of the second strip portion 19b. It flows down in this and is discharged outside the vehicle body without any trouble.

Since the weather strip 19 has a pair of lips 21 and 22 in the second strip portion 19b, when the door 6 is closed, the gap between the door 6 and the front pillar 2 is the second. It is filled with the strip portion 19. That is, one lip 22 blocks the entrance of the gap between the door 6 and the pillar 3. For this reason, the concave groove as shown in FIG. 6 is eliminated, and it is possible to prevent turbulence of the airflow when the vehicle is running, and to prevent wind noise.

Moreover, although the second strip portion 19b has a pair of lips 21 and 22, it is not formed in a cylindrical closed cross-section, so that when the door 6 is closed, both The lips 21 and 22 are easily elastically deformed and the air easily escapes, so that the air is less likely to be trapped in the vehicle interior. Therefore, it is possible to prevent a problem that a large force is required when closing the door 6 and prevent the operability from being lowered.

Further, even when foreign matter enters the inside of the flow path 24 of the second strip portion 19b or the water inside is frozen, the door 6 is opened to easily remove the foreign matter from between the lips 21 and 22. Therefore, the operability of the door 6 can always be maintained in an optimum state.

The first strip portion 19a and the second strip portion 19b are partially different from each other in cross-sectional shape as described above. However, in order to smoothly guide the rainwater, this cross-sectional shape is changed to both strip portions 19a. , 19b, it is desirable to change gradually and continuously instead of abruptly. Normally, the corner strip 25 shown in FIG. 3 is interposed between the first strip portion 19a and the second strip portion 19b to connect them, but the cross-sectional shape of the corner piece 25 is changed to the first strip portion. If the shape of 19a is gradually changed to the shape of the second strip portion 19b, the shapes of both portions 19a and 19b do not change abruptly.

In the embodiment shown in FIG. 5, the tip ends of the pair of lips 21, 22 of the second strip portion 19b overlap with each other while receiving pressure from the vehicle interior side surface 6a while the door 6 is closed. In contact with each other, the lips 21 and 22, the base portion 20 thereof, and the connecting portion 23 cooperate with each other to define and form a flow path 24 having a closed cross section for guiding the rainwater flowing out from the first strip portion 19a. There is. The other structure of the embodiment shown in FIG. 5 is the same as the previous embodiment shown in FIGS. 1 to 4. Note that, also in FIG. 5, the free state of both the lips 21 and 22 is shown by a chain line.

The weather strip 19 has a function of receiving rainwater transmitted through the roof 1 and guiding it to the outside of the vehicle body, and also has a weatherstrip original sealing function for preventing rainwater, wind, or sound from entering the vehicle interior. However, in the embodiment shown in FIG. 5, when the door 6 is closed, the tips of the pair of lips 21 and 22 come into contact with each other, so that the lip 21 is attached to the inner surface 6 a of the door 6. The area is larger than that in the case of FIG. Therefore, the above-described sealing function of the weather strip 19 can be further enhanced, and a sealing function equivalent to that of the tubular weather strip 19 shown in FIG. 7 can be obtained.

The present invention can be applied not only to trucks but also to weather strips in various automobiles such as passenger cars, and also when the weather strip extends from the roof to the center pillar or the quarter pillar. It is possible.

[0034]
