DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for mounting a door belt molding (hereinafter simply referred to as molding) of an automobile.

[0002]

2. Description of the Related Art A belt molding is attached to a window frame of an automobile door for the purpose of dust-proofing and waterproofing. Conventionally, a resin clip has been used for the mounting operation. FIG. 4 shows a state where the molding M 'is attached by the clip C'. The mounting operation has a procedure in which the clip C 'is first attached to the molding M' side, and then attached to the door outer panel P (hereinafter simply referred to as panel P). That is, the clip C ′ has a holding piece 20 that is the engaging base 21 of the molding M ′.
The panel P is attached to the molding M ', and is fixed to the panel P by the engagement with the retaining claws 23 together with the clamping by the tongue pieces 22 for clamping.

[0003]

However, the mall M '
Is formed by inserting the metal core 24, and it is inevitable that the opening width (the dimension W shown in FIG. 4) for the panel P varies to some extent. On the other hand, it is necessary to widen the front end side of the holding tongue piece 22 for the work of inserting the panel P. For this reason, interference with the molding M 'is a problem. However, if the molding M' has already interfered with the molding M 'at the time of assembly, the molding M' is pushed outward and immediately deformed. For this reason, in the prior art, interference has been avoided by providing a certain gap between the holding tongue piece 22 and the molding M '. However, due to this, Mall M
When the 'is pressed from the outside, the molding M' and the clip C 'come into contact with each other and rub against each other, causing unexpected noise. In particular, since the surface layer of the molding M 'is formed of vinyl chloride, which is likely to cause abnormal noise, the abnormal noise is clearly heard from the outside. Further, as a result of the provision of the gap between the tongue piece 22 for holding and the molding M 'in this manner, when assembling to the panel P, it is erroneously pushed into this gap. Work problems also occurred.

[0004] In view of the above-mentioned problems, the present invention has as its object to provide a clip for preventing occurrence of abnormal noise and erroneous assembly.

[0005]

In order to achieve the above-mentioned object, in order to achieve the above-mentioned object, a cross-section having a bent section facing the inside and outside of the vehicle across the door panel of the vehicle and having a generally U-shaped cross section which opens downward is provided. In a synthetic resin clip for fixing the door belt molding formed in the shape of a letter along the upper edge of the door panel, a substrate having a means for preventing the door panel from coming off against the side surface of the door panel. A holding piece that is formed by folding back from the lower edge of the board toward the vehicle interior and that can hold the bent piece on the inside of the door belt molding with an elastic force; A tongue for holding the door panel elastically, and a lower edge of the tongue are connected to each other via a thin hinge piece.
The lower surface is a lower guide surface of a downward slope, and when the clip is pre-attached to the door belt molding, the tip thereof abuts on the inner surface of the bent piece on the outside of the vehicle in the door belt molding ,
The projection is mounted on the door panel, and is formed of a flexibly deformable protruding piece which elastically contacts when the door belt molding is pressed from the outside.

[0006] The clip is first attached to the mall side by inserting the bent piece on the vehicle interior side of the mall into the holding piece and holding it. In this state, the protruding piece has already contacted the bent piece on the outside of the mall without any gap. Next, when the door panel is pushed between the substrate and the tongue for clamping, the door panel is clamped by the tongue for clamping and is prevented from falling off by the retaining means for the substrate. In this manner, the molding is fixed to the door panel. At this time, the protruding piece is in a state of being pressed against the door panel by the spring force of the thin hinge piece.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. First, the mall M and the door panel P on which the mall M is mounted will be briefly described. FIG. 1 shows an upper part of a panel P of an automobile, and a door glass G moves up and down between a door inner panel (not shown). Further, a reinforcement L for reinforcement is joined to the upper part of the inner surface of the panel P (the surface on the door inner panel side). In the lean hose R, mounting holes 1 for mounting clips are formed at predetermined intervals along the width direction. The molding M is formed by inserting a core metal 2 inside and coating the surface with a vinyl chloride material. The vertical cross section has a substantially U-shaped downward shape, and the opening width is set so that the upper edge of the panel P can be covered with the clip C attached. A fin 3 that can be flexibly deformed is formed on the outside of the vehicle among the opening edges, and the adhesion to the panel P is ensured. On the other hand, on the inner surface of the molding M facing the door glass G, two-stage sealing pieces 4 are integrally formed so as to protrude along the width direction, respectively, and the tips of the sealing pieces 4 are applied to the door glass G. . Both seal pieces 4 are door glass G
And has good flexibility to follow up and down movements, and secures sealing between the two. The lower side of the seal piece 4 is an engagement base 5 for insertion into the clip C.

Now, the clip C of this embodiment will be described. The clip C is integrally formed of a synthetic resin material (polyacetal in this embodiment). The clip C has a substrate 6 which comes into contact with the lean hose R, and a square window 7 is opened at the center thereof, and a flexible portion capable of engaging with the mounting hole 1 is provided from a lower edge thereof. The retaining claw 8 is formed to project obliquely. The lower edge of the substrate 6 is folded back toward the door glass G with a predetermined folding width to form a holding piece 9 for holding the engaging base 5 of the molding M. The holding piece 9 has elasticity so that the insertion opening 10 formed between the holding piece 9 and the substrate 6 can be expanded, and an inner edge of the free end side thereof has a locking claw 11 along the width direction. Are formed, and can be engaged with the engagement base 5 of the molding M. However, the center of the side surface of the holding piece 9 is the retaining claw 8
Due to the structure of the molding die, the cutout is cut out by a width substantially corresponding to the window 7.

On the other hand, the upper side of the substrate 6 is formed to be narrow via the left and right shoulders 12 and is folded back to the outside of the vehicle to form a tongue 13 for holding. The folded width of the holding tongue piece 13 is set so that the panel P can be held with elastic force.
Further, the inside of the lower edge of the tongue piece 13 for holding is formed as a slope that expands downward, and an upper guide surface 14 is formed. Further, at the center of the lower edge of the tongue 13 for holding, a protrusion 16 for rattling prevention having the same width as this is continuously provided via a thin hinge piece 15. Since the protruding pieces 16 are connected by the thin hinge pieces 15, they can be bent inwardly. The front surface of the protruding piece 16 is formed with a pressing surface 16a which is formed as an inclined surface so that it can be in close contact with the inner surface of the protruding piece 16 when it is mounted on the molding M. Conversely, the lower surface of the protruding piece 16 is a downwardly inclined surface, and the lower guide surface 17 is formed.

The distance from the substrate 6 to the tip of the projecting piece 16 is set so as to be able to press against the inner surface of the molding M while bending the thin hinge piece 15 when attaching the clip C to the molding M. The setting is made in consideration of the variation in the opening width of the molding M. Next, a description will be given of a molding mounting operation using the clip of the present embodiment configured as described above. First, the clip C is attached to a predetermined position of the molding M. In this case, the engaging base 5 is pushed between the substrate 6 and the holding piece 9 while the insertion port 10 of the clip C is expanded by the engaging base 5 of the molding M. In this way, the engagement base 5 is held by the holding pieces 9, and is prevented from coming off by engagement with the locking claws 11.

Next, attachment to the panel P is performed.
That is, the upper end of the panel P is adapted to the opening between the projecting piece 16 and the substrate 6. In this case, since the tip of the projecting piece 16 is in contact with the inner wall surface of the molding M regardless of the variation in the opening width of the molding M as described above, the panel P is located between the projecting piece 16 and the molding M. An erroneous assembly that is erroneously inserted into the connector is reliably avoided. Further, when the clip C is inserted, the lower guide surface 17 and the upper guide surface 14 can guide the inside of the opening, so that the insertion operation can be performed smoothly.

Then, the panel P is elastically held between the panel 6 and the tongue 13 while pushing the tongue 13 in accordance with the pressing operation of the clip C, and the retaining claw 8 is engaged with the mounting hole 1. By fitting, it is mounted in a state where it is prevented from falling off. When the mounting operation of the molding M is completed in this manner, the thin hinge piece 15 is further bent by the amount that the tongue piece 13 for holding is pushed and spread in accordance with the pushing into the panel P, whereby the protruding piece 16 becomes a pressing surface. The inner surface of the molding M is pressed against the inner surface of the molding M with a predetermined elastic force via the contact 16a. Therefore, when the molding M is pushed from the outside, the protruding pieces 16 also follow and bend and deform in the contact state, so that generation of abnormal noise due to friction can be effectively eliminated.

[0013]

Since the present invention is configured as described above, the following effects can be obtained. By providing a protruding piece that can be bent and deformed by a thin hinge, it absorbs the variation in the opening width of the molding and abuts the inner surface of the molding when the clip is attached to the molding, so the insertion position when assembling to the door panel There is no mistake. Therefore, a proper assembly state can be reliably realized. In addition, even if the molding is pushed from the outside, the projecting pieces follow and bend and deform, so that the generation of abnormal noise due to the friction between the molding and the clip can be avoided.
