Description

  The present invention relates to a mounting structure for an opening trim that has a substantially U-shaped cross section and is attached to a flange formed along a vehicle body opening edge, for example, a door opening edge or a trunk room opening edge, via a non-drying sealer. .

As shown in FIGS. 10, 11 and 12, a flange F is formed along the vehicle body side opening edge facing the door D of the automobile, and an opening trim 10 extending in the longitudinal direction is attached to the flange F. . Here, an example in which the two flanges F1 and F2 are overlapped is shown, but the number of the flanges F is overlapped by various numbers such as one, two, three, and four.
The opening trim 10 includes a left side wall portion (here, a vehicle inner side wall portion) 11, a right side wall portion (here, a vehicle outer side wall portion) 12, and a rear wall portion 13 that is formed by connecting both side wall portions 11, 12. It is U-shaped, and the flange F is inserted from the substantially U-shaped opening 10a side. Lip portions 14 to 17 for holding the inserted flange F are formed inside the substantially U-shaped side wall portions 11 and 12.

Further, a non-drying sealer S is inserted between the front end portion of the flange F and the back wall portion 13 to achieve water tightness, sound insulation and rust prevention. In addition, a core material 18 having a substantially U-shaped cross section is embedded in the opening trim 10 along its shape to ensure rigidity and a strong assembling force against the flange F.
A hollow seal portion 19 is integrally formed on the outside of the right wall portion 12 so as to elastically contact the door D and seal the inside and outside of the vehicle.

However, in the opening trim 10 shown in the conventional example, the non-drying sealer S is filled on the back wall portion 13 side of the opening trim 10, so the non-drying sealer S includes the inside of the back wall portion 13 and the left and right side wall portions 11, 12, that is, a state that extends to the width L of the substantially U-shaped opening 10 a.
As a result, when the opening trim 10 is attached to the flange F, as shown in FIG. 12, the front end of the flange F comes into contact with the non-drying sealer S, but about half of the width L of the substantially U-shaped opening 10a is about There is a problem that the tip of the flange F does not contact, that is, an unnecessary portion is generated, and the non-drying sealer S is wasted correspondingly.

On the other hand, Patent Document 1 describes an invention for reducing the amount of the non-drying sealer S. For that purpose, the non-drying sealer S is formed from the left and right side wall portions 11 and 12 and the back wall portion 13 side. It is necessary to provide a lip portion for keeping the amount of use in a small range.
Thus, when the dedicated lip portion is provided, there is a problem that the structure becomes complicated and the lengths of the left and right side wall portions 11 and 12 are increased.

  Accordingly, an object of the present invention is to provide an opening trim mounting structure that can easily reduce the amount of non-drying sealer used.

It is characterized by doing.

Further, the invention described in claim 2 is a substantially U-shaped cross section composed of a back wall portion (23) in which the left and right side wall portions (21, 22) and the both side wall portions (21, 22) are connected to each other. Lip portions (24 to 27) for holding flanges (F) formed along the vehicle body opening edge of the automobile inserted from the opening portion (20a) side are provided inside the both side wall portions (21, 22). In addition, a non-drying sealer (S) is inserted between the front end of the flange (F) and the back wall (23), and the both side walls (21, 22) and the back wall (23). And an opening trim (20) mounting structure in which a core material (28) is embedded along
A bulging portion (B) that bulges further inward is formed inside a left corner portion where the left side wall portion (21) and the back wall portion (23) are continuously provided, and the right side wall portion ( 22), a groove (20b) having a width (T) narrower than the width (L) of the opening (20a) is formed, and the non-drying sealer (S) is accommodated in the groove (20b). It is characterized by that.

  Furthermore, in the invention described in claim 3, the portion (28a) of the core member (28) embedded in the left corner portion is curved or bent along the inner surface of the bulging portion (B). It is characterized by.

A groove (20b) having a width (T) narrower than a width (L) of the opening (20a) is formed, and the non-drying sealer (S) is accommodated in the groove (20b).

  In the invention according to claim 5, the left corner portion bulged toward the inside interferes with the lip portion (24) provided inside the flange (F) and the left side wall portion (21). It is characterized by not letting it be.

  The invention according to claim 6 is characterized in that a seal portion (29) that elastically contacts the opening / closing body (D) of the automobile is provided outside the right side wall portion (22).

  The symbols in the above parentheses correspond to the symbols described in the drawings and embodiments of the invention described later.

  According to the first aspect of the present invention, the non-drying sealer is inserted, and the opening trim mounting structure in which the core member is embedded connects the left side wall portion and the back wall portion of the opening trim. The left corner is bent or bent so as to bulge inward along with the core material, and a groove for accommodating the non-drying sealer is formed between the bent or bent portion and the right side wall. The insertion position of the non-drying sealer is stabilized.

Further, since the width of the formed groove is narrower than the width of the opening of the opening trim, the non-drying sealer has a back wall portion of the opening trim as in the conventional opening trim (FIGS. 11 and 12). It does not extend to the width of the substantially U-shaped opening such as the range surrounded by the inner side and the left and right side walls. In other words, since the non-drying sealer only needs to extend in the width of the groove portion, when the opening trim is attached to the flange, the unnecessary portion of the non-drying sealer in which the tip of the flange does not contact is compared with the conventional example. Can be reduced.
As a result, the total amount of the non-drying sealer is reduced, so that the weight of the opening trim can be reduced and the cost can be reduced.

  Moreover, since the left corner part which connects the left side wall part and back wall part of an opening trim is curved toward an inner side of an opening trim with a core material, the external shape of an opening trim can be made compact.

  Further, in order to keep the amount of the non-drying sealer used in a small range, it is not necessary to provide a dedicated lip portion as shown in Patent Document 1, and the left corner portion is curved toward the inside of the opening trim together with the core material. The structure is simple because it only needs to be bent.

The invention according to claim 2 of the present invention forms a bulging portion that bulges further inwardly on the inner side of the left corner portion connecting the left side wall portion and the back wall portion of the opening trim. Since the groove part for accommodating the non-drying sealer is formed between the bulging part and the right side wall part, the insertion position of the non-drying sealer is stabilized and the front end of the flange is provided as in the invention of claim 1. Unnecessary portions of the non-drying sealer that do not come into contact with each other can be reduced.
Further, since it is not necessary to curve the left corner portion together with the core material, the manufacturing is easy.

In the invention according to claim 2 of the present invention, as in the invention according to claim 3, the portion of the core material embedded in the left corner portion is curved or bent along the inner surface of the bulging portion. It is also possible to ensure rigidity.
In addition, the core portion embedded in the corner portion is not particularly bent or bent inward, so that, for example, the material of the bulged portion where the core member is not embedded is used for the left and right side wall portions and the back wall portion. Rigidity can also be ensured by making it harder than the constituent material.

Further, according to the invention described in claim 4 of the present invention, it is possible to stabilize the insertion position of the non-drying sealer and suppress the spread of the non-drying sealer without using a core material in the opening trim. Since the groove part for eliminating this can be formed, the weight can be reduced by not providing the core material. Moreover, the material cost and the manufacturing cost for embedding a core material can be reduced, and productivity can be improved.
Even if the core material is not embedded, rigidity can be ensured by forming the left wall portion, the right wall portion, and the back wall portion with a material harder than the lip portion.

  According to the invention described in claim 5 of the present invention, the left corner portion bulged inward is prevented from interfering with the flange and the lip portion provided on the inner side of the left side wall portion. There is no particular deterioration in performance and sound insulation.

  Further, as in the invention described in claim 6 of the present invention, a seal portion that elastically contacts the opening / closing body of the automobile, such as a door, can be provided outside the right side wall portion.
