Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side molding end member formed at an end of a side molding.
In particular, the present invention relates to a side molding terminal member that can be elastically deformed following a change in the shape of an automobile body.

[0002]

2. Description of the Related Art As a conventional end member of this type of side molding, there is a technique shown in FIGS.

FIG. 6 is a bottom view showing the back side of a conventional side molding, and FIGS. 7 to 9 are sectional views showing a state in which the conventional side molding is attached to an automobile body. FIG. 10 is a bottom view showing the back side of the terminal member of another conventional side molding together with the side molding, and FIG. 11 is a sectional view taken along line BB of FIG.

The terminal member 50 of the side molding shown in FIGS. 6 to 9 is integrally formed by injection molding on the end portion of the main body (not shown) of the side molding, and the back surface 51 is adhered to the back surface 51 by means of the double-sided tape 52. Is attached to a predetermined portion of the body 1. Then, as shown in FIG. 7, the terminal member 50 is usually attached to the surface of the body 1 in a close contact state without a gap.

Further, the terminal member 60 of the side molding 2 shown in FIGS. 10 and 11 has a plurality of lightening portions 61 formed by recessing a plurality of portions on the back surface in the longitudinal direction, and the peripheral portion and the lightening portion 61. The protruding portion between them serves as a support rib 62 for adhering the double-sided tape 52. As a result, the weight of the terminal member 60 is reduced, the elastic deformation of the terminal member 60 is facilitated, the followability to the shape change at the time of attachment to the body 2 is enhanced, and the appearance quality after attachment is secured.

[0006]

The conventional side molding terminal member 50 shown in FIGS. 6 to 9 is constructed as described above and has a high rigidity because it is entirely solid, and its longitudinal and width directions are large. Elastic deformation in all directions including is not sufficient. Therefore, when the mounting surface of the body 1 has a change in shape such as a curved surface, the side molding is displaced, the dimensional accuracy of the side molding or the body 1 is not accurate, and the side molding is unevenly assembled, as shown in FIGS. 8 and 9. As described above, a gap G is generated between the mounting surface of the body 1 and the back surface 51 of the terminal member 50, which may impair the appearance quality. In this case, the terminal member 50 may have a shape corresponding to the shape change of the body 1 at the time of its injection molding, but again, due to the displacement of the side molding, the error in the dimensional accuracy of the side molding or the body 1, and the like. Similarly, a gap G may occur between the mounting surface of the body 1 and the back surface 51 of the terminal member 50.

Further, since the terminal member 60 of the conventional side molding 2 shown in FIGS. 10 to 11 is provided with the lightening portion 61 extending in the longitudinal direction, elastic deformation in the width direction becomes easy,
Although the conformability to the shape change of the body 1 is improved, the conformability to the shape change particularly in the longitudinal direction is not sufficient at a complicated portion such as a fender portion where the shape change is large, and similar to the above, There may be a gap between the mounting surface of the body 1 and the back surface of the terminal member 60, which may cause a defective appearance.

[0008] Therefore, an object of the present invention is to provide a side molding terminal member having reduced rigidity and improved followability to a change in the shape of the mounting surface of the body.

[0009]

In the terminal member of the side molding according to the second aspect of the present invention, a large number of pillars are erected in a predetermined area on the back surface side of the flat plate-shaped design portion constituting the design surface side to form a deformation permitting portion. It is a thing.

[0011]

In the invention of claim 1, the lightening portion reduces the rigidity of the terminal member, and the slit provided at a predetermined position in the longitudinal direction of the supporting rib reduces the rigidity of the supporting rib in the longitudinal direction, It facilitates elastic deformation of the terminal member. Therefore,
The terminal member is easily elastically deformed in accordance with the arrangement position of the lightening portion and the arrangement position of the slit of the supporting rib, and even if there is a change in shape such as a curved surface of the mounting surface of the body, the shape change can be reliably followed. .

EXAMPLES Examples of the present invention will be described below.

FIG. 1 is a bottom view showing the back side of the terminal member of the side molding according to the first embodiment of the present invention together with the side molding.

In the figure, the same reference numerals and symbols as those of the conventional example indicate the same or corresponding parts as those of the conventional example, and therefore, redundant description will be omitted.

In the figure, the terminal member 1 of the side molding 2 is shown.
Reference numeral 0 denotes a unit integrally formed at the end of the side molding 2 by injection-molding polyvinyl chloride (PVC), for example, and is disposed at a fender portion or the like of an automobile body. The terminal member 10 is provided with a plurality of lightening portions 11 recessed so as to extend linearly in the longitudinal direction and arranged at predetermined intervals in the width direction. A supporting rib 12 extending in the longitudinal direction is formed between the peripheral edge portion of the terminal member 10 and the adjacent lightening portions 11, and the adjacent lightening portions are provided at predetermined positions in the longitudinal direction of each supporting rib 12. A slit 13 communicating with 11 is formed. In the present embodiment, the slits 13 of the support ribs 12 are arranged at one position on each support rib 12 and at positions displaced in the longitudinal direction.

The terminal member 10 of the side molding 2 of the present embodiment constructed as described above is attached to a predetermined position on the body of an automobile by adhering a double-sided tape to the supporting ribs 12 on the back surface thereof, as in the conventional example. . At this time, when the surface shape of the body of the automobile is curved or the like and changes vertically or horizontally, etc., the terminal member 10 is appropriately elastically deformed in accordance with the shape change and adhered to the body surface via the double-sided tape. Will be required. That is, the side molding 2 of this embodiment
Corresponding to the shape change of the body surface,
A desired shape change such as bending or twisting is applied, and the double-sided tape on the back side is reliably adhered following the shape change on the body surface. At this time, the slits 13 provided in the lightening portion 11 and the support ribs 12 respectively reduce the rigidity of the terminal member 10 and facilitate the elastic deformation of the terminal member 10 in a desired direction. Therefore, since the terminal member 10 itself also reliably follows the shape change of the body surface with a small pressing force, variations in dimensions and the like when mounted on the body are absorbed, and the back surface of the terminal member 10 as in the conventional example is absorbed. There is no gap between the surface of the body and the surface of the body, resulting in poor adhesion or poor appearance. Since the double-sided tape for adhering the terminal member 10 is usually made of acrylic foam, it absorbs deformation such as expansion and contraction due to bending of the side molding 2 itself.

Thus, the side molding 2 of the above embodiment.
The terminal member 10 has a plurality of lightening portions 11 linearly recessed in the longitudinal direction, forms a supporting rib 12 between the adjacent lightening portions 11, and supports the ribs 12 at a predetermined position in the longitudinal direction. A slit 13 is formed at a position for communicating the adjacent lightening portions 11 with each other.

Therefore, in the above embodiment, the lightening portion 11 extending in the longitudinal direction lowers the rigidity in the width direction of the terminal member 10 to facilitate elastic deformation in the width direction, and the supporting rib 12 in the longitudinal direction. The slits 13 provided at predetermined positions reduce the rigidity of the support ribs 12 in the longitudinal direction, and
Facilitates elastic deformation in the longitudinal direction of the. Therefore, the terminal member 10 can be easily elastically deformed in all directions including the longitudinal direction and the width direction, and even if the mounting surface of the body has a vertical or horizontal shape change such as a curved surface, the shape change can be reliably performed. To follow. As a result, no gap is formed between the body and the mounting surface, the body is reliably bonded to the mounting surface, and the appearance quality can be stably and favorably maintained. Further, since the terminal member 10 of the above-described embodiment can be easily elastically deformed to cope with the change in the shape of the body, it is not necessary to manufacture the terminal member 10 into a shape corresponding to the change in the shape of the body, and the whole may be formed in a flat plate shape. Therefore, the mold fabrication becomes easy. Next, another embodiment according to the present invention will be described below.
Only the differences from the first embodiment will be described in each embodiment, and the same components as those in the first embodiment will be designated by the same reference numerals and the description thereof will be omitted.

In the figure, the end member 20 of the side molding of the second embodiment has a number of slits 23 formed in the same supporting ribs 22 as the supporting ribs 12 of the terminal member 10 of the side molding of the first embodiment. The support rib 22 is characterized in that it is provided at a plurality of locations, and the other configurations are similar to those of the first embodiment. That is, a plurality of slits 23 (three places in the second embodiment) are formed in each supporting rib 22 of the terminal member 20 at predetermined intervals in the longitudinal direction, and the slits 23 of each supporting rib 22 substantially correspond to the upper and lower sides. It is located in a position.

The side molding terminal member 20 of the second embodiment configured as described above, in addition to the lightening portion 11 extending in the longitudinal direction, is supported in the same manner as the side molding terminal member 10 of the first embodiment. The plurality of slits 23 provided at predetermined positions in the longitudinal direction of the rib 22 facilitate elastic deformation of the terminal member 20 in all directions including the longitudinal direction and the width direction. Therefore, even when the mounting surface of the body has a vertical or horizontal shape change such as a curved surface, the terminal member 20 reliably follows the shape change with a smaller pressing force than the first embodiment. as a result,
No gap is formed between the body and the mounting surface, the body is more reliably bonded to the mounting surface, and the appearance quality can be stably and favorably maintained.

The slits 35 provided at predetermined positions in the longitudinal direction of the supporting ribs 34 reduce the rigidity of the supporting ribs 34 in the longitudinal direction and facilitate the elastic deformation of the terminal member 30 in the longitudinal direction. Further, in the central portion thereof, the deformation permitting portion 32 including a large number of columnar objects allows elastic deformation of the terminal member 30 in all directions. Therefore, the terminal member 30 is easily elastically deformed in all directions including the longitudinal direction and the width direction over the entire region thereof, and even when the mounting surface of the body has a vertical or horizontal shape change such as a curved surface. Reliably follow shape changes.
