Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a clip for mounting a door belt molding (hereinafter, simply referred to as a molding) of an automobile.

[Prior Art] A belt molding is attached to a window frame portion of an automobile door for the purpose of dustproofing and waterproofing. Conventionally, a resin clip has been used for the mounting work. FIG. 4 shows a situation in which the molding M'is attached by the clip C '.

For the mounting work, first, the clip C ′ is attached to the molding M ′ side, and then the door outer panel P (hereinafter simply referred to as the panel P).
Say. ) Side is attached. That is, the clip C ′ is attached to the molding M ′ by the holding piece 20 holding the engaging base portion 21 of the molding M ′, and the clip C ′ is held by the holding tongue piece 2 with respect to the panel P. It is fixed by engagement by the retaining claw 23.

[Problems to be Solved by the Invention] By the way, since the molding M ′ is formed by inserting the core metal 24, the opening width (W dimension shown in FIG. 4) with respect to the panel P varies to some extent. It is inevitable. On the other hand, the holding tongue piece 22 needs to be widened at the tip side in order to insert the panel P. Therefore, interference with the molding M ′ becomes a problem, but if it already interferes with the molding M ′ at the time of assembling, the molding M ′ is pushed outward and is immediately deformed. From these things,
Conventionally, a certain gap is provided between the holding tongue piece 22 and the molding M'to avoid interference.

However, when the molding M ′ is pushed from the outside due to this, the molding M ′ and the clip C ′ come into contact with each other and rub against each other, resulting in an 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 was clearly audible from the outside.

Further, assembling in which the gap is provided between the sandwiching tongue piece 22 and the molding M ′ in this way, and when the panel P is assembled, the assembly is erroneously pushed into this gap. There were also problems in work.

Therefore, in view of such conventional problems, an object of the present invention is to provide a clip which prevents occurrence of abnormal noise and erroneous assembly.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a cross section having a bending piece that straddles a door panel of an automobile and faces the inside and the outside of the vehicle, and is opened downward as a whole. In a clip made of synthetic resin for fixing the door belt molding formed in a substantially U-shape along the upper edge of the door panel, a side wall of the door panel is abutted to prevent upward disengagement of the panel. A board having the same, a holding piece formed by folding back from the lower edge of the board to the inside of the vehicle and capable of holding a bent piece on the inside of the vehicle in the door belt molding with elastic force, and folding back from the upper edge of the board to the outside of the vehicle. A sandwiching tongue that is formed to elastically sandwich the door panel and a tongue that is continuously connected from the tongue through a thin hinge piece. When the clip is attached to the door belt molding, the tip thereof is the doorbell. It is configured by a flexibly deformable projecting piece that comes into contact with or comes close to the inner surface of the bent piece on the vehicle outer side of the mall and that makes elastic contact with or comes into contact with the bent piece when it is mounted on the door panel.

[Operation] The clip is first attached to the molding side by inserting the bending piece on the inside of the molding car into the holding piece and holding it. In this state, the projecting piece is already in contact with the bent piece on the vehicle outer side of the molding without any gap. Next, when the door panel is pushed between the substrate and the sandwiching tongue, the door panel is sandwiched by the sandwiching tongue and is prevented from coming off by the substrate retaining means. In this way, the molding is fixed to the door panel. At this time, the projecting piece is pressed against the door panel by the spring force of the thin hinge piece.

Embodiments Embodiments embodying the present invention will be described in detail below with reference to the drawings.

First, the molding M and the door panel P on which the molding M is mounted will be briefly described.

FIG. 1 shows an upper portion of a panel P of an automobile, and a door glass G is vertically movable between a door inner panel (not shown). Further, a reinforcement lean hose R for reinforcement is joined to the upper part of the inner surface of the panel P (the surface on the door inner panel side). Then, mounting holes 1 for mounting clips are formed in the lean hose R at predetermined intervals along the width direction.

The molding M is formed by inserting the core metal 2 inside and covering the surface with a vinyl chloride material. The vertical cross section has a substantially U-shape facing downward, and the opening width is set so that the upper edge of the panel P can be covered with the clip C attached. In addition, a fin edge 3 that can be flexibly deformed is formed on the outer side of the vehicle among the opening edges, and the adhesion to the panel P is secured. On the other hand, on the inner surface of the molding M facing the door glass G, two illustrated seal pieces 4 are integrally projected in the width direction, and the respective tips are applied to the door glass G. . Both seal pieces 4 are both door glass G
It has a good flexibility to follow the vertical movement of the and secures the sealing property between the two. Further, below the seal piece 4 is an engaging base portion 5 for inserting into the clip C.

Now, the clip C of this example will be described. The clip C is integrally formed of a synthetic resin material (polyacetal in this example). The clip 1 has a base plate 6 that abuts against the lean hose R, and a rectangular window portion 7 is opened in the center portion thereof, and a flexibility that enables engagement with the mounting hole 1 is provided from the lower edge thereof. The retaining claw 8 is obliquely formed so as to project.

Further, the lower edge of the substrate 6 is folded back to the door glass G side with a predetermined folding width to form a holding piece 9 for holding the engagement base portion 5 of the molding M. This holding piece 9 is the substrate 6
It has elasticity so that the insertion opening 10 formed between the opening and the end can be expanded, and a locking claw 11 is formed along the width direction at the inner edge of the free end side of the molding M. Can be engaged with the engaging base portion 5. However, the central portion of the side surface of the holding piece 9 is cut out by a width substantially corresponding to the window portion 7 due to the mold structure of the mold for forming the retaining claw 8.

On the other hand, the upper side of the substrate 6 is formed to be narrow through the left and right shoulders 12 and is folded back to the outside of the vehicle,
A sandwiching tongue piece 13 is formed. The folding width of the sandwiching tongue piece 13 is set so that the panel P can be sandwiched by the elastic force. Also, the tongue for clamping
The inside of the lower edge of 13 is an inclined surface that expands downward, and an upper guide surface 14 is formed. Further, a rattling prevention projection 16 having the same width as that of the thin tongue piece 15 is continuously provided at the central portion of the lower edge of the sandwiching tongue piece 13 via a thin hinge piece 15. Since the protruding pieces 16 are connected by the thin hinge pieces 15, the protruding pieces 16 can be flexibly deformed inward. In addition, the front surface of the projecting piece 16 is formed with a pressing surface 16a that is an inclined surface that can be brought into close contact with the inner surface of the projecting piece 16 when mounted on the molding M. Conversely, the protruding piece 1
The lower surface of 6 is a downward slope and a lower guide surface 17 is formed.

The distance from the substrate 6 to the tip of the projecting piece 16 is set so that when the clip C is attached to the molding M in advance, the thin hinge piece 15 can be bent and pressed against the inner surface of the molding M. It is set in consideration of variations in the opening width.

Next, a molding mounting operation using the clip of this example configured as described above will be described.

First, the clip C is attached to a predetermined position of the molding M, respectively. In this case, the engagement base 5 is pushed between the base plate 6 and the holding piece 9 while the insertion base 10 of the clip C is expanded by the engagement base 5 of the molding M. By doing so, the engagement base 5 is held by the holding piece 9 and is prevented from coming off by the engagement with the locking claw 11.

Next, the panel P is attached. That is, the upper end of the panel P is fitted to the opening between the projecting piece 16 and the substrate 6. In this case, since the tip of the protrusion 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 protrusion 16 and the molding M. Wrong assembly that would be mistakenly plugged in is surely avoided. Also, when inserting the clip C, the lower guide surface
Since it is possible to guide into the opening by the 17 and the upper guide surface 14, the insertion work can be performed smoothly.

Thereafter, the panel P is elastically pinched between the panel P and the substrate 6 while pushing out the pinching tongue 13 according to the pushing operation of the clip C, and the retaining pawl 8 engages with the mounting hole 1. It is installed in a state where it is prevented from coming off. When the mounting work of the mall M is completed in this way,
The thin hinge piece 15 is further bent by the amount of the pinching tongue piece 13 or the panel P being pushed and expanded, whereby the thin hinge piece 15 is further bent to the inner surface of the molding M via the projecting piece 16 and the pressing surface 16a. Press contact with a predetermined elastic force. Therefore, the mall M
When is pressed from the outside, the protruding piece 16 also follows it and flexibly deforms in the abutting state, so that the generation of abnormal noise due to friction can be effectively eliminated.

[Advantages of the Invention] Since the present invention is configured as described above, the following effects can be exhibited.

By providing a projecting piece that can be flexibly deformed by a thin hinge, the clip is attached to the molding so as to absorb the variation in the opening width of the molding and contact the inner surface of the molding.
There is no mistake in the insertion position when assembling to the door panel. Therefore, the proper assembled state can be surely realized.

Further, even if the molding is pushed from the outside, the projecting piece follows it and is flexibly deformed, so that the generation of abnormal noise due to the friction between the molding and the clip can be avoided.
