[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a belt molding for an automobile, which uses a small number of clips and has an excellent sealing property.

[0002]

[Prior art]

 As shown in FIG. 8, the automobile 5 is provided with a belt molding 6 in contact with the window glass 7 at the belt line 55 of the door 50. The belt molding 6 is extruded using an elastic member such as vinyl chloride resin or rubber. In addition, after extrusion molding, partial bending is performed to reduce molding resistance and air resistance.

As a result, the shape of the belt molding 6 can cope with the change of the window glass 7 into a complicated three-dimensional curve. As shown in FIGS. 4 and 5, the belt molding 6 has an upper seal lip 61 protruding toward the window glass 7 and a lower seal lip 62. Further, the belt mold 6 has a seal lip 64 that abuts on the lip abutting surface 82 of the door panel 8 and a lower protruding portion 63. As a result, the belt molding 6 seals and decorates the belt line 55 near the door. Both the upper and lower seal lips 61, 62 have pile flocking parts 611, 612.

By the way, when the belt molding 6 is attached to the door panel 8, a clip 9 is used as shown in FIGS. 4 to 7. Here, the clip 9 has a belt mold locking portion 91, a U-shaped main body 92, and a panel locking portion 93. Therefore, the lower protrusion 63 of the belt molding 6 is inserted into the U-shaped body 92. After that, the panel locking portion 93 of the clip 9 is engaged in the mounting hole 80, and the belt molding 6 is mounted on the door panel 8. As a result, the belt molding 6 exhibits the decorative effect and the protective effect of the door while ensuring the sealing property between the window glass 7 and the door panel 8.

[0005]

[Problems to be solved]

 However, the above conventional technique has the following problems. In other words, in recent years, the door panel has been curved at each part due to consideration of air resistance and molding, and along with this, the panel contact piece itself has been bent after extrusion to match it. However, the curved shape of the belt molding 6 and the shape of the door panel 8 may slightly differ due to variations in processing. In this case, as shown in FIGS. 6 and 7, the belt molding 6 is held by the clip 9 at the portion where the clip 9 is present. Therefore, the belt molding 6 is correctly positioned at a predetermined position near the door panel 8. On the other hand, as shown in both figures, in the free portion E where the clip 9 is not provided, the belt mold 6 does not contact the door panel 8 and the gap D exists between them. Therefore, in the free portion E, the belt molding 6 is easily deformed, and the gap C due to the deformation is more likely to be generated as shown in FIGS. 6 and 7.

That is, as shown in FIG. 5, in the free portion E, the belt molding 6 moves toward the window glass 7 side and is deformed, and a normal distance A is maintained between the window glass 7 and the door panel 8. It cannot be kept and cannot be placed in the specified position. As a result, a gap 99 (a gap between C + D) is generated between the belt molding 6 and the smooth surface 81, the sealing property is deteriorated, and the belt molding 6 is in a meandering state, so that the door decoration property is deteriorated. There is a case.

Therefore, in order to solve the above problem, it is conceivable to increase the number of clips 9 used, but in this case, the door panel 8 must be provided with a large number of clip mounting holes, and the rigidity of the door panel 8 is lowered. . Further, the work of attaching the clip 9 increases, and the workability of attaching the belt molding 6 deteriorates.

If a large number of clips 9 are used, some of them may be fatigue-damaged and fall off between the door panels 8. Therefore, when running, abnormal sound may be generated by the damaged clip 9. The present invention has been made in view of such conventional problems. It uses a small number of clips, keeps a constant distance between the belt molding and the door panel, and is excellent in decorativeness and sealing performance. Is to provide.

[0009]

 The present invention is a belt molding, which is provided on a door panel of a belt line in an automobile and has a sealing lip that comes into contact with a window glass that moves up and down, wherein a pressing member is attached to the belt mold, and the pressing member is a belt. It consists of a mounting base with a U-shaped cross section that fits in the bottom of the molding, and an elastic arm that extends from the mounting base in the direction of the window glass. The mounting base is between the door panel and the belt molding. The belt mold for an automobile is characterized in that it has a panel contact piece located therein, and that the arm portion has a pile flocked portion on the contact surface with the window glass.

What is most noticeable in the present invention is that a pressing member is attached to the lower portion of the belt molding, and the pressing member includes a mounting base having a U-shaped cross section having a panel contact piece and the arm portion. is there. The pressing member is fitted and attached to the belt molding between the clips in the belt molding (portion E in FIGS. 6 and 7). Examples of the material of the pressing member include nylon (polyamide resin), polyacetal resin, and polypropylene resin. The pressing member is made by, for example, extrusion molding or extrusion molding.

In addition to elasticity, the nylon is particularly excellent in abrasion resistance, chemical resistance, oil resistance, and mechanical strength. In addition to elasticity, polyacetal is also excellent in impact strength, heat resistance, and durability. In addition to elasticity, polypropylene resin is also particularly excellent in heat resistance, chemical resistance, impact resistance, and moldability. The arm portion has a pile flocking portion made of, for example, nylon pile or polyester pile. The flocked pile is formed by implanting short fibers (pile) such as nylon into the window glass contact surface of the arm by electrostatic induction. This improves the design, softness and sealing of the arm. Therefore, scratches on the window glass can be reduced.

The mounting base has a substantially U-shaped fitting portion that is in contact with an automobile door panel and has a rigidity to fit the lower portion of the belt molding. The door panel consists of an outer panel and an inner panel. The belt molding is attached, for example, to the outer panel of the belt line, and is partially attached to the inner panel. The belt molding has, for example, an upper sealing lip and a lower sealing lip. The upper sealing lip shall be attached so that it always contacts the window glass.

[0013]

[Action and effect]

 In the belt molding of the present invention, a pressing member is attached to the lower portion of the belt mold between the clips. Therefore, the arm part of the pressing member is always in contact with the window glass, and the belt molding and the pressing member are pushed toward the door panel. Further, since the pressing member is attached with its panel contacting piece in contact with the door panel, there is no gap between the door panel and the belt molding as in the conventional case.

As a result, the pressing member and the belt molding are arranged in a state where they are always in contact with the window glass on the one hand and the door panel on the other hand, that is, in the normal position, at all the mounting portions. Therefore, the space between the pressing member, the belt molding, the window glass, and the door panel is kept in the normal position. Therefore, the belt molding completely seals the gap between the window glass and the door panel, improving the sealing performance.

Therefore, unlike the conventional case, it is not necessary to use a large number of clips, and the number of clips used can be reduced. Therefore, according to the present invention, it is possible to provide an automobile belt molding that uses a small number of clips, keeps the distance between the belt molding and the door panel constant, and is excellent in decoration and sealing.

 A belt molding for a vehicle according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the belt molding 6 of this example has an upper seal lip 61 which is disposed on the door panel 8 of the belt line 55 (see FIG. 8) of the automobile 5 and which comes into contact with the ascending / descending window glass 7.

A pressing member 1 is attached to the lower protrusion 63 of the belt molding 6 as shown in FIG. As shown in FIG. 2, the pressing member 1 includes a U-shaped attachment base 12 that fits in the belt molding 6 and an elastic arm portion extending from the attachment base 12 toward the window glass 7. It consists of 11. Further, the mounting base 12 has a panel contact piece 121 located between the door panel 8 and the belt molding 6. As shown in FIGS. 1 and 2, the arm portion 11 has a pile flocking portion 111 on the contact surface with the window glass 7.

The pile flocking portion 111 is made of a filament-shaped nylon pile. The nylon pile has a yarn diameter of about 10 to 20 denier and an average length of 3 to 5 mm. The pile flocked portion 111 is flocked at a portion in contact with the window glass 7 by an electric flocking method or the like via an adhesive. The pressing member 1 is extruded using a polyacetal resin. In addition to its excellent elasticity, polyacetal resin is particularly excellent in impact resistance, heat resistance, and durability.

The arm portion 11 is formed in a shape in which various thicknesses and lengths are changed so as to correspond to the deformed shape of each portion of the window glass 7. Therefore, the arm portion 11 has flexibility such as flexibility and bending characteristics capable of coping with changes in the up-and-down angle of the window glass 7. As shown in FIGS. 1 and 2, the mounting base 12 is composed of a panel contact piece 121 that abuts the inner panel flat portion 81 of the door panel 8 and a locking projection 123 having a curved portion 122 and has a cross section U. It has a letter shape.

As shown in FIG. 2, the mounting base 12 has a substantially U-shaped locking groove 120 between the panel contact piece 121 and the locking projection 123. As shown in FIG. 1, the locking groove 120 fits into the lower protrusion 63 of the belt molding 6. In this state, the panel abutment piece 121 is positioned between the belt molding 6 and the inner panel flat portion 81. The panel contact piece is joined to the inner panel flat portion 81 by a joining means such as an adhesive.

As shown in FIG. 1, the belt molding 6 has an upper seal lip 61 and a lower seal lip 62. Further, it has a lower protrusion 63 and a seal lip 64 that abuts the seal abutting surface 82 of the door panel 8. Between the lower protrusion 63 and the lower seal lip 62, there is a U-shaped groove 60 for engagement with which the engagement protrusion 123 of the pressing member 1 is fitted. The belt molding 6 has a core metal 83 as shown in FIG. On the other hand, when attaching the belt molding 6, as shown in FIG. 3, the clip 9 other than the portion where the pressing member 1 is provided is attached to the attaching hole 80 of the door panel 8. Next, the belt molding 6 is attached to the pressing member 1. Although the clip 9 is separately illustrated in the pressing member 6 in FIG. 3, both are integrally formed. That is, the clip 9 is provided on a portion other than the mounting base 12.

In this way, as shown in FIG. 1, the belt molding 6 is disposed between the window glass 7 and the door panel 8, and the pressing member 1 is attached below the belt molding 6. Further, the pile flocking part 111 at the tip of the above-mentioned arm part 11 is attached so as to be constantly in contact with the window glass 7.

Next, the function and effect will be described. As shown in FIG. 1, the pressing member 1 is attached to the lower protrusion 63 of the belt molding 6 of this example. Therefore, as shown in FIG. 1, the pile flocking part 111 of the arm part 11 is constantly in contact with the window glass 7 to move the belt molding 6 and the mounting base part 12 toward the inner panel flat part 81 side of the door panel 8 in the arrow direction. It will be pushed. Further, since the pressing member is mounted in a state where the panel contact piece 121 is in contact with the door panel 72, there is no gap between the door panel 8 and the belt molding 6 as in the conventional case.

As a result, as shown in FIG. 1, the pressing member 1 and the belt molding 6 have a normal distance A, that is, a state in which one is in contact with the window glass 7 and the other is in contact with the door panel 8, that is, at all attachment sites. It is placed in a normal position. Therefore, the space between the pressing member 1, the belt molding 6, the window glass 7, and the door panel 8 is kept in a normal position. Therefore, the pressing member 1 and the belt molding 6 completely seal the gap between the window glass 7 and the door panel 8, and the sealing performance is improved.

The above operation will be described in more detail with reference to FIGS. First, as shown in FIG. 5, in the conventional belt molding 6, in a case where the clip 9 is not attached, the belt molding 6 is deformed to the state of being in contact with the window glass 7 in an extreme case. Here, the space B occupied by the deformed portion of the belt molding 6 changes depending on the mounting position of the belt molding 6. Therefore, the lower protrusion 63 of the belt molding 6 is separated from the inner panel flat portion 81 of the door panel 8.

As a result, a gap 99 (gap of C + D) is formed between the belt molding 6 and the door panel 8 as shown in FIG. Therefore, the sealing performance between the belt mold 6 and the door panel 8 by the belt molding 6 is deteriorated. On the other hand, in the belt molding 6 of this example, as shown in FIG. 1, the pressing member 1 pushes the belt molding 6 toward the door panel 8 in the arrow direction.

Therefore, as shown in FIGS. 1, 4 and 5, the belt molding 6 is pushed and moved to the door panel 8 side by the distance C. Therefore, the belt molding 6 is arranged with the normal distance A maintained. At this time, the pressing member 1 always occupies the space between the belt molding 6 and the door panel 8 only by the thickness D of the panel contact piece 121. This also applies to the thickness D of the clip 9 as shown in FIG.

As described above, according to the present embodiment, as shown in FIG. 5, the pressing member 1 and the belt molding 6 are always kept at C (A-B) by the elastic action of the arm portion 11 of the pressing member 1. ) Will be pushed to the door panel 8 side. Therefore, as shown in FIG. 1, there is no gap (see FIG. 5) between the belt molding 6 and the door panel 8, particularly between the seal lip 64 and the lip contact surface 82 of the door panel 8. As a result, the sealing property between the belt molding 6 and the door panel 8 is improved.

Therefore, unlike the conventional case, it is not necessary to use a large number of clips 9, and the number of clips used can be reduced. Therefore, according to this example, the number of clips used is small, the distance between the belt molding 6 and the door panel 8 is kept constant, the sealing property is excellent, and there is no fear of meandering and the like, and the decorative property is also excellent.
