Description

  The present invention relates to side molding.

  The side molding is a plate-shaped synthetic resin part that is attached to the lower part of both sides of a vehicle body such as an automobile. The side molding is attached for the purpose of protecting both sides of the vehicle body, improving aesthetics (designability) on both sides of the vehicle body, or reducing air resistance.

  The side molding includes a bracket that is directly attached to the lower portion of the door panel, and a side molding body that is attached to the bracket. The bracket and the side molding body are connected to each other without any gap between the lower ends of the bracket and the side molding using a fastening member such as a clip (see Patent Document 1).

Japanese Utility Model Publication No. 3-28051

In the conventional side molding, the clip that connects the bracket and the side molding main body may be visible from the outside of the door panel, and the design is impaired.
In addition, since the bracket and the side molding main body have a large variation in dimensions, it is difficult to connect them using a clip, so that accurate dimension management is required. For this reason, an increase in manufacturing cost is invited.

In view of this, there has been proposed a side molding in which the bracket and the side molding main body are connected at locations other than the lower end portions of each other, and a gap is formed between the lower end portions so as not to be affected by variations in dimensions.
However, when sand, pebbles (sandstone), etc. enter the internal space formed between the bracket and the side molding body from this gap, there is a problem that it is not discharged (it is difficult to discharge). For this reason, sandstone moves in the internal space of the side molding and makes an unpleasant noise.

  This invention is made | formed in view of the situation mentioned above, and it aims at proposing the side molding which can discharge | emit the sandstone which penetrate | invaded interior space easily, without impairing design nature.

In order to solve the above problems, the following means were adopted.
The side molding according to the present invention is a side molding that is attached to the lower end of a door panel of a vehicle, and includes a bracket that is exposed to the inside of the door panel and a side molding body that is exposed to the outside of the door panel. The bracket and the side molding main body are connected to each other by forming a gap along the longitudinal direction between the lower ends of the bracket and the side molding body, and an internal space formed between the bracket and the side molding main body. A discharge hole for discharging the invading sandstone is formed.

  The discharge hole may be formed by a thin portion in which a thickness of a part of a lower end portion of the side molding body is reduced.

  The thin-walled portion is formed so that a plate thickness gradually decreases toward a lower end portion of the side molding body.

  The lower end portion of the side molding body is formed to be inclined obliquely downward toward the vehicle interior side.

  The discharge hole is formed so that the shape of the outer edge of the hole does not appear on the inner ridge line when the lower end portion of the bracket is viewed from the vehicle inner side and the outer ridge line when the lower end portion of the side molding body is viewed from the vehicle outer side. Features.

  The discharge hole is characterized in that it opens to the inner space side than a virtual plane connecting the outer ridge line and the inner ridge line.

  According to the present invention, it is possible to realize a side molding that can easily discharge sandstone that has entered the internal space. Moreover, the discharge hole which discharges sandstone can be formed, without impairing the design property of a side molding.

  As shown in FIG. 1, the side molding 10 is a plate-shaped synthetic resin part that is attached to the lower part of the door panel 2 of the automobile 1. The side molding 10 is mounted for the purpose of protecting the door panel 2, improving the aesthetics (designability) on both sides of the automobile 1, or reducing the air resistance.

The side molding 10 includes a bracket 20 attached so as to be exposed on the vehicle inner surface 2b side of the door panel 2, and a side molding body 30 attached so as to be exposed on the vehicle outer surface 2a side of the door panel 2.
The bracket 20 is formed into a shape along the body 3 that is exposed on the side of the vehicle inner surface 2b of the door panel 2 and exposed below the door panel 2 (see FIG. 5).
The side molding body 30 is formed such that the surface 30a is exposed to the vehicle outer surface 2a side of the door panel 2 and is integrated with the vehicle outer surface 2a of the door panel 2 to improve the aesthetic appearance (designability).

  Both the bracket 20 and the side molding body 30 are elongated plate-shaped synthetic resin parts. The lengths of the bracket 20 and the side molding body 30 in the longitudinal direction (the longitudinal direction of the automobile 1) are substantially the same. The vertical length of the bracket 20 is about half of the vertical length (height) of the side molding body 30.

As shown in FIG. 2, the bracket 20 is attached (assembled) with the back surface facing the lower portion of the back surface 30 b of the side molding body 30. The bracket 20 and the side molding body 30 are fastened (coupled) to each other by a small screw 40 at a plurality of locations (see FIG. 5C).
Thereby, the entire lower part of the back surface 30 b of the side molding body 30 is covered with the bracket 20.

  As shown in FIG. 3, an internal space S is formed between the bracket 20 and the side molding body 30. The internal space S is formed over the entire length of the side molding 10 in the longitudinal direction. The internal space S is an elongated thin plate-shaped space along the front-rear direction of the door panel 2 (the automobile 1).

After assembling the side molding 10 by attaching the bracket 20 to the side molding main body 30, the side molding 10 is attached to the lower part of the vehicle panel 2 a of the door panel 2. The side molding 10 is attached to the door panel 2 using a double-sided tape or the like.
The side molding 10 is mounted (arranged) such that the lower portions of the bracket 20 and the side molding body 30 protrude downward from the lower end of the door panel 2 (see FIG. 5). Thereby, the surface 20a of the bracket 20 is exposed at the lower end of the vehicle inner surface 2b of the door panel 2. Further, the surface 30 a of the side molding body 30 is exposed at the lower end of the vehicle outer surface 2 a of the door panel 2.

FIG. 4 is an enlarged view of the IV in FIG. 3A and shows the discharge hole 52.
FIG. 5 is a longitudinal section of the side molding 10. (A) is Va-Va sectional drawing of Fig.3 (a), Comprising: It is a cross section containing the discharge hole 52. FIG. FIG. 3B is a cross-sectional view taken along the line Vb-Vb in FIG. FIG. 3C is a cross-sectional view taken along the line Vc-Vc in FIG. 3A and includes a fastening portion (screw fastening) between the bracket 20 and the side molding body 30.
FIG. 6 is a diagram showing the gap 50. FIG. 5A is an enlarged view of VIa in FIG. 5A, and is an enlarged cross-sectional view including the discharge hole 52. FIG. 5B is an enlarged view of VIb in FIG. 5A, and is an enlarged cross-sectional view that does not include the discharge hole 52.

  A gap 50 is formed at the lower end of the inner surface 10 b of the side molding 10 along the longitudinal direction of the side molding 10. The gap 50 is a space formed because the lower end portion 22 of the bracket 20 and the lower end portion 32 of the side molding main body 30 are not in close contact with each other and are separated from each other. The gap 50 is formed over the entire length of the side molding 10 in the longitudinal direction.

The lower end 22 of the bracket 20 is bent outward from the vertical state. The tip 23 of the lower end 22 is formed in a horizontal state toward the vehicle exterior.
On the other hand, the lower end portion 32 of the side molding body 30 is gradually inclined toward the vehicle inner side from the vertical state. The tip 33 of the lower end 32 is formed in a horizontal state toward the vehicle inner side below the tip 23.
A gap 50 is formed between the tip 23 of the lower end 22 of the bracket 20 and the tip 33 of the lower end 32 of the side molding body 30. For this reason, the gap 50 opens in the inner surface 10 b of the side molding 10.

As shown in FIG. 4, a discharge hole 52 having a larger gap dimension than the gap 50 is formed in a part of the gap 50. The discharge hole 52 is provided to discharge sand and pebbles (sandstone) that have entered the internal space S of the side molding 10 to the outside.
For example, the gap dimension t1 of the gap 50 is 2 mm, and the gap dimension t2 of the discharge hole 52 is 3 to 4 mm. The length of the discharge hole 52 in the longitudinal direction is, for example, 30 mm. For example, four (portions) of the discharge holes 52 are formed at equal intervals in the entire length of the gap 50.

As shown in FIG. 5 and FIG. 6, the discharge hole 52 is formed by a thin portion 35 obtained by thinning a portion of the tip 23 of the bracket 20 and a tip 33 of the side molding body 30.
As shown in FIGS. 5A and 6A, the tip 33 of the side molding body 30 has a thickness (thickness) of about 2 to 3 mm at a portion where the discharge hole 52 is not formed. doing.
On the other hand, as shown in FIG. 6B and FIG. 6B, a portion of the tip 33 where the discharge hole 52 is formed is formed with a thickness (thickness) of about 1 to 2 mm. The
Thereby, the discharge hole 52 is formed corresponding to the thin part 35 which is a thin part of the tip 33 of the side molding main body 30 than the other part.

  Further, the thin portion 35 forming the discharge hole 52 is formed so that the thickness gradually decreases toward the tip 33 of the side molding body 30. The thickness of the thin portion 35 is about 2 to 3 mm on the upper side of the lower end portion 32 of the side molding body 30, gradually decreases toward the tip 33, and about 1 mm at the tip.

  Thus, since the thin part 35 becomes thin gradually as it goes to the front-end | tip 33, resin moldability is maintained favorable. In other words, at locations where the wall thickness changes suddenly, the fluidity of the molten resin deteriorates and sink marks (Sink Marks or Shrink Marks) tend to occur. However, since the thickness of the thin portion 35 is gradually reduced, the fluidity of the molten resin does not deteriorate and sink does not occur. For this reason, the aesthetic appearance (designability) of the side molding main body 30 is not impaired.

  In addition, the lower end portion 32 of the side molding body 30 is formed in a shape that is inclined obliquely downward toward the vehicle interior toward the thin portion 35 (discharge hole 52) formed at the tip 33. For this reason, sand and pebbles that have entered the internal space S of the side molding 10 roll downward along the lower end portion 32 of the side molding main body 30 and are easily discharged to the outside from the discharge hole 52.

As shown in FIGS. 6A and 6B, in the lower end portion 22 of the bracket 20, the shape where the discharge hole 52 is not formed and the position where the discharge hole 52 is formed match the shape of the surface 20a. To do. For this reason, even if the side molding 10 (bracket 20) is viewed from the vehicle inner side, the discharge hole 52 cannot be visually recognized. That is, the outer edge shape of the discharge hole 52 does not appear on the ridge line (inner ridge line 20R) of the lower end portion 22 of the bracket 20.
Therefore, the aesthetic appearance (designability) of the lower end portion 22 of the bracket 20 can be maintained without deteriorating.
The inner ridge line 20R is a ridge line when the side molding 10 (the lower end portion 22 of the bracket 20) is viewed from the vehicle inner side (see FIG. 6A).

As shown in FIGS. 6A and 6B, in the lower end portion 32 of the side molding body 30, the portion where the discharge hole 52 is not formed and the portion where the discharge hole 52 is formed are the shape of the surface 30 a. Match. For this reason, even if the side molding 10 (side molding main body 30) is viewed from the outside of the vehicle, the discharge hole 52 cannot be visually recognized. That is, the outer edge shape of the discharge hole 52 does not appear on the ridge line (outer ridge line 30 </ b> R) of the lower end portion 32 of the side molding body 30.
Therefore, the aesthetic appearance (designability) of the lower end portion 32 of the side molding body 30 can be maintained without deteriorating.
The outer ridge line 30R is a ridge line when the side molding 10 (the lower end portion 32 of the side molding main body 30) is viewed from the vehicle outer side (see FIG. 6A).

Further, the gap 50 and the discharge hole 52 are opened closer to the inner space S than the virtual plane K connecting the inner ridge line 20R and the outer ridge line 30R.
That is, the distal end 23 of the bracket 20 and the distal end 33 of the side molding body 30 are formed in a horizontal state, and the distal end 33 is positioned on the vehicle outer side with respect to the proximal end (inner ridge line 20R) of the distal end 23. For this reason, the outer ridge line 30R (tip 33) of the side molding body 30 is located below and on the vehicle outer side with respect to the inner ridge line 20R (base end of the tip 23) of the bracket 20.
Accordingly, the gap 50 and the discharge hole 52 are formed closer to the inner space S than the virtual plane K connecting the outer ridge line 30R and the inner ridge line 20R while forming the gap 50, the gap 50, and the discharge hole 52 between the tip 23 and the tip 33. Can be opened.
Therefore, it becomes difficult to visually recognize the gap 50 and the discharge hole 52 from the outside. In other words, the gap 50 and the discharge hole 52 cannot be visually recognized from the inside of the vehicle and the outside of the vehicle unless the passenger intentionally approaches the ground. Therefore, the appearance (designability) of the side molding 10 is not impaired by the gap 50 and the discharge hole 52.

In the side molding 10, sandstone enters the internal space S from the gap 50 and the gap in the front-rear direction (see FIG. 3A) while the automobile 1 is traveling. Since a molding error (variation in dimensions) occurs between the bracket 20 and the side molding body 30, it is necessary to provide a gap 50 and the like. For this reason, intrusion of sandstone into the internal space S is inevitable.
Once sandstone enters the internal space S, the sandstone moves through the internal space S while the automobile 1 is traveling, and generates unpleasant sound. In conventional side molding, it has been difficult to discharge sandstone that has entered the internal space.
On the other hand, in the side molding 10, since the discharge hole 52 is provided in a part of the gap 50, sandstone that has entered the internal space S can be easily discharged.

  Thus, in the side molding 10, the discharge hole 52 is provided in a part of the gap 50 formed at the lower end of the side molding 10. By reducing the gap dimension t1 of the gap 50, it becomes difficult for sandstone to enter the internal space S. On the other hand, by providing the discharge hole 52 having the gap dimension t2 larger than the gap 50, the sandstone that has entered the internal space S can be easily discharged.

  Since the discharge hole 52 is formed by the thin portion 35 provided at the lower end portion 32 (tip 33) of the side molding main body 30, the shape change of the side molding main body 30 can be suppressed to the minimum, and the aesthetic appearance (design) Can be maintained without damage.

  Since the thin part 35 is formed so that the plate thickness is gradually reduced toward the lower end part 32 (tip 33) of the side molding body 30, the molten resin can be sufficiently spread to prevent the occurrence of sink marks.

  Since the lower end portion 32 of the side molding body 30 is formed so as to be inclined obliquely downward toward the vehicle interior side, sandstone that has entered the internal space S can be reliably guided toward the discharge hole 52.

Since the discharge hole 52 is formed so that the shape of the outer edge of the hole does not appear on the inner ridge line 20R of the bracket 20 and the outer ridge line 30R of the side molding body 30, the appearance (designability) of the lower end of the side molding 10 is not impaired. Can be maintained.
In particular, the gap 50 and the discharge hole 52 are maintained without impairing the aesthetic appearance (designability) of the lower end of the side molding 10 because the virtual plane K connecting the inner ridge line 20R and the outer ridge line 30R opens to the inner space S side. it can.

  The various shapes and combinations of the constituent members shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

The arrangement, dimensions, quantity, and the like of the discharge holes 52 can be changed as appropriate.
Although the case where the thin part 35 is provided in the front-end | tip 33 of the side molding main body 30 as a means to form the discharge hole 52 was demonstrated, it is not restricted to this. A thin portion may be provided at the tip 23 of the bracket 20.
