Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a weatherstrip mounting structure to be mounted on a vehicle body of an automobile.

[Conventional technology]

Various weather strips are attached to a vehicle body including a door, a lid for a luggage compartment, a hood panel and the like in order to maintain a sealing property of an internal space such as a vehicle compartment, a luggage compartment or an engine compartment.

Such a weather strip is usually attached to the vehicle body by fitting a large number of clips previously attached to the weather strip side into the attachment holes formed in the vehicle body.

However, according to such a weatherstrip mounting structure, a large number of clips must be fitted into the mounting holes of the vehicle body one by one, so that not only the workability at the time of mounting the weatherstrip is deteriorated, but also the weather between the clips is reduced. The strip portion may be lifted and the weather strip sealing function may be deteriorated. In addition, the problem that rust easily occurs in the mounting hole of the vehicle body is inevitable.

In order to eliminate the above-mentioned inconvenience, a mounting structure for fixing the weather strip to the vehicle body with a double-sided adhesive tape has also been proposed. With this configuration, the weather strip can be fixed to the vehicle body through the double-sided adhesive tape over its entire length,
Since it is not necessary to form a mounting hole in the vehicle body, it is possible to prevent rusting of the mounting hole and prevent lifting of the weather strip. The workability of attaching the weather strip can be improved.

However, since the weather strip is fixed to the vehicle body with the double-sided adhesive tape, the weather strip cannot be easily removed from the vehicle body after the attachment. Therefore, when the weather strip deteriorates with time or is damaged, it is not easy to replace it with a new one. The weather strip must be forcibly removed, the double-sided adhesive tape attached to the vehicle body must be removed over time, and then a new weather strip must be attached to the vehicle body again with the double-sided adhesive tape.

[Problems to be solved by the device]

An object of the present invention is to provide a weatherstrip mounting structure for an automobile in which the above-mentioned conventional drawbacks are eliminated by a simple structure.

[Means for Solving the Problems]

In order to achieve the above object, the present invention proposes a vehicle weatherstrip mounting structure in which a base member is fixed to a vehicle body of an automobile and a weatherstrip is detachably fitted to the base member.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the external appearance of an automobile, and reference numeral 1 is a side door forming a part of a vehicle body 2. As shown in FIG. 2, the door 1 has a door main body 3 and a door frame 4, and a weather strip 5 is attached to a peripheral portion of the inside of the vehicle as shown in FIG. As shown in FIG. 3, the weather strip 5 is made of an elastic material such as rubber or a relatively soft synthetic resin, has a hollow portion 6 inside, and extends long along the peripheral portion of the door 1. When the door 1 is closed as shown in FIGS. 1 and 3, the weather strip 5 is pressed against the vehicle body portion that defines the door opening, that is, the rocker panel 7 in FIG. Seal.

FIG. 3 is a view showing details of a weatherstrip mounting structure according to the present invention. Before clarifying the structure, the conventional weatherstrip mounting structure described above will be briefly described with reference to the drawings. . Conventionally, as shown in FIG. 6, a large number of clips 8a are attached to a weather strip 5a in advance at predetermined intervals, and these clips 8a are fitted into attachment holes 9a formed in the door 1, The weather strip 5a was attached to the door 1 by. According to this structure, since a large number of clips 8a must be fitted into the mounting holes 9a one by one when the weather strip 5a is mounted, the above-mentioned various drawbacks such as reduced workability cannot be avoided.

Further, as shown in FIG. 7, a mounting structure is also known in which the weather strip 5b is fixed to the door 1 by the double-sided adhesive tape 10b over the entire length thereof, but in this configuration, as described above, the weather strip 5b is used. Once attached to the door 1, it is not easy to replace it with a new one.

Therefore, in the weatherstrip mounting structure according to the present invention shown in FIG. 3, the double-sided adhesive tape is attached to the peripheral portion of the door 1.
The base member 12 also shown in FIG. 4 is fixed by an adhesive 11 or an adhesive, and an engaging groove 15 formed in the base 14 of the weather strip 5 is formed in the engaging protrusion 13 formed in the base member 12. It is detachably fitted. In this way, the weather strip 5
However, it is attached to the door 1 through the base member 12 over its entire length.

The base member 12 has substantially the same length as the weather strip 5 and extends along the peripheral edge of the door 1.

To attach the weather strip 5 to the door 1, use the base member 12
After being fixed to the door 1 with the double-sided adhesive tape 11, the weather strip 5 may be fitted and fixed to the base member 12. Alternatively, the base member 12 and the weather strip 5 may be first fitted to each other, and then the base member 12 may be fixed to the door 1 by the double-sided adhesive tape 11.

According to the weatherstrip mounting structure described above, the base member
Since 12 is fixed to the door 1, there is no fear that the weather strip 5 fitted and supported by the door 12 will float.
In addition, the engagement projection 13 of the base member 12 and the engagement groove 15 of the weather strip 5 can be brought into close contact with each other, and the gap between them can be eliminated. Therefore, a high sealing property can be secured, and a problem that rainwater or wind enters the vehicle interior can be prevented. Further, when the weather strip 5 is attached to the door 1, since it is not necessary to use a clip, the attaching workability is improved, and since it is not necessary to form an attaching hole in the door 1, rusting of the door can be suppressed.

Further, since the base member 12 and the weather strip 5 are simply fitted to each other, the weather strip 5 can be easily removed from the base member 12 when the weather strip 5 deteriorates with time or is damaged. A new weather strip can be easily fitted and fixed to the base member 12 again.

The weather strip 5 is made of an elastic material as described above. However, if the weather strip 5 is too soft, the weather strip 5 easily comes off the base member 12, which is not preferable. Therefore, the weather strip 5 as a whole may be made of a relatively hard elastic material to enhance the joint rigidity between the weather strip 5 and the base member 12 and prevent the weather strip 5 from coming off. Is less likely to be deformed, the adhesion to the vehicle body 2 is reduced, and the sealing function is impaired.

Therefore, in the illustrated embodiment, the base portion 14 of the weather strip 14 fitted to the base member 12 as shown in FIG. 3 is made of, for example, a high-density sponge rubber or a solid rubber as shown by double hatching. Body 2 made of a relatively hard material
The weather strip portion 16 that comes into contact with and elastically deforms is made of a material softer than the base portion 14 such as low density sponge rubber. As a result, the weather strip 5 can be prevented from being easily disengaged from the base member 12 during its normal use, and furthermore, the weather strip 5 abuts on the vehicle body 2 and is easily elastically deformed, and a high sealing property can be secured.

In order to prevent the weather strip 5 and the base member 12 from coming off,
The base member 12 may also be made of a rigid body such as metal or hard synthetic resin, but if the rigidity is too great, it will be difficult to attach it along the corner X (Fig. 2) of the door 1, so the weather Like the base portion 14 of the strip 5, it is desirable that the strip portion 5 is made of high-density sponge rubber or solid rubber. At this time, in order to facilitate bending and deformation of the portion of the base member 12 attached to the corner portion X of the door 1 in conformity with the corner portion, a notch 17 or a notch is formed in this base member portion as shown in FIG. When set, the base member 12 can be easily fixed to the door 1.

Further, as shown in FIG. 3, when a mark is formed on the door 1 to which the base member 12 is fixed by a bead 18 or the like and the base member 12 is attached with this as a reference, the base member 12 is fixed at a predetermined position. Can be fast and accurately fixed to.

In the example shown in FIG. 3, the engaging projection 13 is formed on the base member 12,
Although the engaging groove 15 is formed in the weather strip 5, it is needless to say that conversely, the engaging groove may be formed in the base member 12 and the engaging protrusion may be formed in the weather strip 5 so as to be fitted therein. is there.

The mounting structure of the weatherstrip attached to the door 1 of the automobile has been described above. However, the present invention relates to a weatherstrip mounted on the luggage compartment lid 20 or the hood panel 21 shown in FIG. 1 or other vehicle body parts. It is also applicable to the mounting structure.
