Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip for an automobile, and more particularly, to a gap formed between one side of a vehicle and a front end of a wall approaching substantially perpendicularly to the one side, for example, an automobile. The present invention relates to a device that seals a gap between a fender and a body.

[0002]

2. Description of the Related Art A conventional automotive weather strip will be described with reference to FIGS.

As shown in FIG. 7, a rear edge of a front fender 1 of an automobile is in contact with a front edge of a door panel 3. As shown in FIG. 8, the rear wall 1a of the front fender 1 and the body surface 2
A gap 4 is formed between the gap 4a.

Conventionally, the gap 4 is sealed with a weather strip in order to prevent wind and water from entering the tire house. This is because the wind from the tire house causes wind noise when passing through the gap 4, and in cold regions, etc., water entering from the gap 4 freezes near the door hinges, and the door is closed. This is because it may not open.

The applicant of the present invention has proposed a weather strip for sealing the gap 4 between the fender 1 and the body 2 as follows.
The weather strip 100 shown in FIG. 9 has been previously proposed (Japanese Patent Application No. 11-126292).

The weather strip 100 has a substantially triangular cross section, has elasticity in its height direction, and has a hook portion 101 at the top. Then, when assembling the vehicle, the base 102 of the weatherstrip, which is the bottom of the triangle, is brought into contact with the body surface 2a, and is slid into the gap 4 by utilizing the elasticity in the height direction. Then, the tip of the rear wall portion 1a of the fender 1 is locked by the hook portion 101 at the top, and fitted into the gap 4. The assembled weather strip 100 is held in a stable state in the gap 4 by the elasticity in the height direction.

As described above, the weather strip 100
Can be easily assembled to a vehicle and can maintain a stable assembled state.

[0008]

However, since the weather strip 100 has a substantially triangular shape, the cross-sectional area of the product greatly depends on the gap g of the gap 4.
For example, when the gap g of the gap 4 is doubled due to the type of the vehicle, the weather strip 100A having the cross-sectional area = ab / 2 shown in FIG. Both must be doubled to form a weather strip 100B having a cross-sectional area of 2ab, and a product cross-sectional area of about 4
Double. Therefore, the material cost and the number of processing steps increase, and as a result, the cost is greatly increased.

The present invention has been made in view of the above points, and can be easily assembled on a vehicle, and can maintain a stable assembled state. It is an object of the present invention to provide a weather strip for an automobile, the cost of which is less likely to fluctuate due to a change in size.

[0010]

SUMMARY OF THE INVENTION A weatherstrip for an automobile according to the present invention is a weatherstrip for sealing a gap formed between one surface of a vehicle and a tip of a wall approaching substantially vertically toward the one surface. A torso having a hook portion at the top and a substantially inverted Y-shaped cross section including a V-shaped leg supporting the torso, the leg being in contact with the one surface portion,
The hook locks a tip of the wall.

The height of the weather strip can be changed by opening the V-shaped legs. Further, since a force for returning to the original position acts on the opened leg, elasticity is imparted in the height direction of the weather strip. Therefore, when assembling the weatherstrip to the vehicle, the height of the weatherstrip is adjusted by opening the legs while pressing the V-shaped legs against the one-sided surface, so that the height of the weatherstrip can be reduced. Sliding into the gap, the tip of the wall is locked by the hook at the top, and the weather strip is assembled in a positioned state. The assembled weather strip is held in a stable state in the gap by the elasticity in the height direction. Further, since the height of the weather strip can be changed depending on the degree of opening of the legs, even when the gap has a dimensional variation in the longitudinal direction of the weather strip, the variation can be followed. can do.

And, with this weather strip,
Even if the gap becomes large due to differences in vehicle type, etc., it is possible to cope with such a dimensional change of the gap by changing the length of the trunk connecting the leg and the hook. The change in the area is small, and the cost is hardly changed by the change in the gap size to be assembled. In other words, even if the gap of the assembling gap is large, it can be manufactured at low cost.

The weather strip for an automobile of the present invention is preferably used for a weather strip for sealing a gap between a fender and a body. In this case, the one surface portion is a body surface and the wall portion is a fender tip portion extending substantially perpendicularly toward the body surface, and conversely, the one surface portion is a fender surface, The wall may be an end on the body side extending substantially perpendicularly to the fender surface.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of a weather strip 10 for an automobile according to an embodiment of the present invention, FIG. 2 is a cross-sectional view showing a state where the weather strip 10 is mounted on a vehicle, and FIG. FIG.

The weather strip 10 of this embodiment also has
Similar to the above-described conventional weather strip 100, the gap 4 between the rear wall 1a of the fender 1 and the body 2 is sealed at the abutting portion between the front fender 1 and the door panel 3 of the vehicle shown in FIG.

As shown in FIG. 2, the gap 4 is formed between the body surface 2a and the front end of the fender rear wall portion 1a extending substantially perpendicularly to the body surface 2a. Specifically, in the front fender 1 arranged to cover the outside of the body 2, the rear end of the vehicle is a body surface 2 which is a side surface of the body 2 located in front of the front door 3.
By bending inward toward a, a fender rear wall portion 1a is formed, and a gap 4 is secured between the tip end and the body surface 2a.

As shown in FIG. 1, the weather strip 10 is a weather strip having a substantially inverted Y-shaped cross section, and is formed by extruding an elastic material such as rubber or a thermoplastic elastomer. .

As shown in FIG. 2, the weatherstrip 10 has a leg portion 12 having a substantially inverted V-shaped cross section which comes into contact with the body surface 2a, and a trunk extending upward from a branch portion of the leg portion 12. A hook portion 16 is formed at the top (upper end) of the body portion 14 to lock the tip of the fender rear wall portion 1a.

More specifically, in this embodiment, the legs 12
The front and rear legs 12a and 12b have substantially the same length, and the body 14 is erected substantially perpendicularly to the body surface 2a. And the hook part 16 is the tip 1 of the body part 14.
It is formed by a locking projection 18 having a hook-shaped cross section protruding from the front surface of the front end 14a so as to form a concave portion 20 for receiving the front end of the fender rear wall 1a between the front end 4a and the front end 4a. The hook portion 16 is provided with a locking projection 1 forming a front wall of the recess 20 for workability during assembly and prevention of detachment after assembly.
The trunk portion 14 which forms the rear wall of the concave portion 20 rather than the tip 18a of the
Is set higher.

In this weather strip 10, the height h from the lower end of the leg portion 12 to the hook portion 16 is set to be larger than the gap g between the gap 4 between the fender 1 and the body 2, as shown in FIG. In this way, the dimensions are set so that the legs 12 can be attached to the gap 4 with the legs 12 opened.

This weather strip 10 can change the height of the weather strip 10 by deforming the V-shaped legs 12 so as to open them. The elasticity is imparted in the height direction of the weather strip 10 because a force for returning to the original state acts.

When assembling the weather strip 10 to a vehicle, as shown in FIG.
The height of the weather strip 10 is adjusted by opening the leg portion 12 while pressing against the fender 1 so as to slide into the gap 4 between the fender 1 and the body surface 2a. At that time, as shown in FIG.
By inserting the tip of the fender 1 into the recess 20 of the hook 16, the tip of the fender 1 is locked to the hook 16,
Thereby, the weather strip 10 is assembled in a positioned state.

The assembled weather strip 10 includes:
As shown in FIG. 2, an elastic force is generated in the height direction by a force of the opened leg portion 12 to return to the original position, and this elasticity acts as a holding force, so that the gap 4 is held in a stable state.

As described above, the weather strip 10 can be assembled by sliding into the gap 4 between the fender 1 and the body 2, so that the weather strip 10 can be easily assembled. 10 can maintain a stable assembled state.

Also, since the height of the weather strip 10 can be changed depending on the degree of opening of the legs 12, the dimensional variation in the longitudinal direction of the weather strip 10 may occur in the gap 4. Can follow the variation.

In the case of the weather strip 10, the height of the weather strip can be changed by changing the length of the body portion 14.
The contribution of the product cross-sectional area to the gap g of the product is small. For example, as shown in FIG. 4, when assembling a vehicle having the gap 4 twice as large as that of FIG. 2 (interval = 2 g), the length of the body 14 of the weather strip 10 is increased by the increase of the gap 4. In other words, it is possible to cope with this by molding by lengthening the dimension g. Thereby, the product cross-sectional area can be suppressed to increase within 100%, and compared with the conventional weather strip 100 shown in FIG.
Small variations in product cross-sectional area. Therefore, the gap 4 to be assembled is
Can be manufactured at a low cost even if the distance between them becomes large.

FIG. 5 is a sectional view of a weather strip 30 according to another embodiment, and FIG. 6 is a sectional view showing an assembled state thereof. The weather strip 30 differs from the weather strip 10 of the above-described embodiment in the shape of the leg 12 and the direction in which the trunk 14 extends with respect to the leg 12. Hereinafter, components denoted by the same reference numerals as those in the above-described embodiment have the same configuration unless otherwise specified.

In this embodiment, in the weather strip 30 having a substantially inverted Y-shaped cross section, the V-shaped leg 12 is
The length of the front and rear legs 12a and 12b is not the same, and the front leg 12a is set longer. Also, the torso 14
Has the same inclination angle as the rear leg 12b, that is,
The rear leg 12b and the trunk portion 14 extend from the branch portion of the leg portion 12 so as to be on the same straight line. Therefore, in this embodiment, the trunk portion 14 is slightly inclined forward,
A hook 16 is formed at the tip.

Also in this weather strip 30, as shown in FIG. 6, the leg portion 12 is slid into the gap 4 between the fender 1 and the body surface 2a with the leg portion 12 pressed against the body surface 2a and opened, and By locking the front end of the fender 1, the weather strip 30 can be assembled in a simple and stable state as in the above embodiment. Further, similarly to the above-described embodiment, the height of the weather strip can be changed by changing the length of the body portion 14, so that the contribution of the product cross-sectional area to the interval g of the gap 4 to be assembled is small.

In the above embodiment, the structure in which the gap between the rear wall 1a of the front fender 1 and the body surface 2a is sealed has been described. However, the present invention is applicable to other parts of the front fender 1 and other parts. Also applies to the fenders. Also, a configuration has been described in which the gap formed by the tip of the fender being close to the body surface substantially perpendicular to the body surface is sealed. Conversely, the end on the body side extends substantially perpendicular to the fender surface. The same can be applied to the gap formed by the above. Further, the present invention is not limited to the gap between the fender and the body, and can be applied to a structure for sealing various gaps formed by a certain surface portion of a vehicle and a tip of a wall portion approaching substantially perpendicular to the one surface portion. .
