TECHNICAL FIELD The present invention relates to an improvement in a belt molding clip.

<Prior Art> Conventionally, a belt molding clip of this type (hereinafter simply referred to as "clip") has been shown in Figs.

In this clip 1, a panel holding plate 3, a substrate 5, and a molding holding plate 7 are arranged in an S-shape in cross section as shown in FIG. 7, and a pair of engaging pawls 9 are projecting from the lower edge of the substrate 5. I will do it. A panel engaging portion 11 is formed from the panel holding plate 3, the board 5, and the engaging pawl 9, and a molding engaging portion 13 is formed from the molding holding plate 7 and the board 5. The panel holding plate 3 is passed through a clip hole 19 formed in the upper edge 17 of the door outer panel 15 and the board 5 and the board 5 together to form a flange 21 of the door outer panel 15.
And the engaging pawl 9 is engaged with the end edge of the flange 21, the panel engaging portion 11 is engaged with the door outer panel 15 in a clip-fastening manner. On the other hand, the molding engaging portion 13
Attachment part of the belt molding 23 by the molding holding plate 7 and the substrate 5
By sandwiching 25, it is engaged with the belt molding 23 like a clip. As a result, the belt molding 23 is fixed to the door outer panel 15 via the clip 1.

The belt molding 23 in the figure has a seal lip portion 27 that slidably contacts the window glass G, first and second fin portions 29 and 30, and a mounting portion 27.
The insert 31 is buried in the
(See the official gazette).

<Problems to be Solved by the Invention> In the clip 1 having the above-described configuration, since the engaging force with respect to the belt molding 23 depends on the clamping force of the mounting portion 25 by the molding clamping plate 7 and the base 5, problems such as detachment occur. There was a risk of it occurring. Therefore, as seen in the above-mentioned publication, it is considered that a pin is provided on the clip 1 and the pin is driven into the belt molding to enhance the binding force between the two.

On the other hand, as shown in FIG. 1, an engaged rail 35 having a C-shaped cross section is formed on the belt molding, and the undercut of the engaged rail 35 is used to increase the coupling force (engaging force) between the belt molding and the clip. Is newly considered.

An object of the present invention is to provide a clip used for such a novel belt molding.

<Means for Solving the Problems> The present invention is a clip made to achieve the above object, in which a molding engaging portion is spring-elastically deformable and arranged in parallel in the clip width direction with a gap. The invention is characterized in that it has two or more deformed arm portions, and each of the pawl portions is formed at the tip thereof so as to satisfy the following requirements.

(A) The claw portion is formed on one side surface of each deformable arm portion in the clip thickness direction.

(A) At least one pawl is engaged with one inner peripheral surface of the opening peripheral wall of the engaging rail, and the remaining pawls are engageable with the other inner peripheral surface of the opening peripheral wall, respectively. It is formed in the opposite direction.

<Operation> According to the clip having the above-described configuration, when the molding engaging portion is pushed into the engaged rail of the belt molding from the tip end side (that is, the pawl portion side), the deformable arm portion is elastically deformed, and The pawl portion engages with each inner peripheral surface of the peripheral wall of the opening of the engaged rail in a clip-proof manner. And each claw part serves as an undercut stopper to the peripheral wall of the opening.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings (FIGS. 1 to 6).

The clip 41 of the embodiment includes a panel engaging portion 43 and a molding engaging portion 60.
Consists of. The panel engaging portion 43 includes a panel holding plate 47 having a bent tip, a substrate 49 and a substrate 49 wider than the panel holding plate 47.
It is composed of an engaging pawl 51 projecting from the substantially central position of the lower edge portion toward the panel holding plate 47 side. Then, as shown in FIG.
A panel holding plate 47 is inserted into a clip hole 55 formed in the upper edge of the door outer panel 53, and a flange 57 is formed between this and the substrate 47.
And the engaging pawl 51 engages with the end edge of the flange 57, and the clip 41 and the door outer panel 53 are joined together. In the example of the door outer panel 53 shown in the figure, the flange 57
There are two steps, and a clip hole 55 is formed in the inclined portion. As a result, the peripheral portion of the clip hole 55 is less likely to rust.

The molding engaging portion 60 includes three engaging pieces 61, 62a, 62b on the substrate 49.
It is projected from the upper edge. Each engaging part piece 61, 62a, 62b is composed of a deforming arm part 63, 64a, 64b and a pawl part 65, 66a, 66b, and the outer engaging pieces 62a, 62b have the same shape. Each deformed arm 6
The reference numerals 3, 64a, 64b are bent plates and are integrally provided in the width direction so as to project upward from the upper edge of the substrate 49 and with a gap 69 therebetween. Then, at the tip portion thereof, the thickness direction pawls 65, 6
6a and 66b are formed. In this way, each deformed arm 63,6
4a and 64b are separated from each other through the clearance 69 because the engaging pieces 6
This is because when the 1, 62a, 62b are engaged with the engaged rail 35 of the belt molding 33, they can be independently deformed. Also,
They are arranged in the width direction in order to avoid interference between the deformed arm portions.

Out of the two deformable arms 64a, 64b, the pawls 66a, 66b are provided so as to project to the right in the illustrated example, while the pawl 65 is provided so as to project from the central deformable arm 63 to the left. There is. The respective pawl portions 65, 66a, 66b are provided on the respective one side surfaces of the respective deformable arm portions 63, 64a, 64b so that the engaging pieces 61, 62a, 6 are attached to the engaged rail 35.
This is because the deformable arm portions 63, 64a, 64b themselves can be deformed when the 3b is pushed in. In other words, in the configuration in which the claws are provided so as to project from both the front end surfaces of one deformable arm, when the engaging pieces are pushed into the engaged rails and the two are engaged in a clip-stop manner, the deformed parts are clawed. Since there is only a part, the pushing load is high and the workability may be reduced.

In the example shown in the drawings, the deformed arm portion has a bent plate shape, but is not particularly limited as long as it can be deformed in the clip thickness direction. For example, it may be rod-shaped.

If the deformation amount of the deformable arm portion is large, the pawl portion itself may not be deformable. However, in order to reduce the resistance of pushing the engaging pieces 61, 62a, 62b into the engaged rail 35, the pawl portion itself should be plate-shaped as shown in the figure so that the pawl portion itself can be deformed. It is preferable that the upper surface be a curved surface to facilitate slipping, and that the deformed arm portion and the pawl portion are connected by the thin portion 67.

The clip 41 having such a structure is injection molded using a synthetic resin material such as PP having spring elasticity.

Reference numeral G in the drawing indicates a window glass, and the belt molding 33 is provided with two seal lip portions 38 and 39 which are in sliding contact with the window glass. The surface of each seal lip portion 38, 39 is subjected to a general flocking treatment. The belt molding 33 is extruded using a soft polymer material (resin such as PVC or synthetic rubber such as EPDM). An insert 36 is embedded in the engaged rail 35 in order to enhance the shape retaining ability.

Next, a manner of mounting the clip 41 of the embodiment on the belt molding 33 and the door outer panel 53 will be described.

In this clip 41, first, the molding engaging portion 60 is
Then, it engages with the engaged rail 35 of 33 in a clip-fastening manner, then attaches the panel engaging portion 43 to the upper edge of the door outer panel 53 in the same manner as in the conventional example, and thus, the door outer panel 53 and the belt molding 33. To connect.

As one mode of engaging the molding engaging portion 60 of the clip 41 with the engaged rail 35, the molding engaging members 60, 66a, 66b are straightly connected to the opening 37 of the engaged rail 35 from the pawl portions 65, 66a, 66b. Joint section
There is a way to push 60. In this case, each engaging piece 61,6
The deformable arms 63, 64a, 64b are elastically deformed in 2a, 62b, so that the molding engaging portion 60 is engaged with the engaged rail 35 in a clip-stop manner.

As another embodiment, there is a method shown in FIGS. First, the respective claw portions 66a, 66b of the two engaging pieces 62a, 62b located on the outer side are engaged with the inner peripheral surface of the portion 71 on the outer side (the right side in the figure) on the peripheral wall of the opening of the engaged rail 35. Let And the claw 66a,
Pry the clip 41 clockwise around the 66b as shown in FIGS. Then, the central engaging piece 61 interferes with the inner side (left side in the figure) portion 73 on the peripheral wall of the opening, the pawl portion 65 is deformed, and the deformable arm portion 63 is changed to another deformable arm portion.
It deforms so as to intersect 64a and 64b (so-called bend action). Then, as shown in FIG. 1, the engagement piece 61 also engages with the inner peripheral surface of the inner portion 73 of the opening peripheral wall.

With this configuration, when the clip 41 is engaged with the engaged rail 35, the insertion angle of the molding engagement portion 60 with respect to the opening 37 can be widened. Further, since the engaging piece can be deformed by the lever principle, the load required for engaging can be small. Therefore, the workability of attaching the clip 41 to the belt molding 33 is improved.

As shown in FIGS. 3 and 4, the clip 41 is attached to the engaged rail 35.
5 and 6, the upper surface of the pawl portion 65 is used as a curved surface 68, and each curved surface 68 is guided by the sloped surface 75 extending from the opening peripheral wall 73. Piece 61,62a, 6
It is preferable to design 2b. The reason why the curved surface 68 is provided on the pawl portion 65 is to reduce the frictional resistance to the inclined surface 75 and the opening peripheral wall 73. This reduces the load required for engagement. In addition, the pawl portion 65 is gradually deformed to make the load-strain curve smooth. As a result, the engaging work can be performed smoothly.

In the above embodiment, at least two engaging pieces may be used. However, from the viewpoint of preventing the clip 41 from being obliquely attached to the engaged rail 35, as shown in FIG. 2, three or more engaging pieces are provided so that the claw portion can form a virtual isosceles triangle. It is preferable.

<Effects of the Invention> As described above, the clip of the present invention corresponds to a belt molding provided with an engaged rail having a substantially C-shaped cross section, and has a molding engaging portion engageable with the engaged rail. The structure is such that a pawl portion satisfying predetermined requirements is formed at the tip of two or more spring-elastically deformable deformable arms arranged in parallel in the clip width direction with a gap. It is a thing.

Thus, when the molding engaging portion is pushed into the opening of the engaged rail from the side of the pawl, at least the deformable arm is elastically deformed, so that the molding engaging portion is opened in the opening of the engaged rail. It is possible to engage with both inner peripheral surfaces of the part peripheral wall in a clip-like manner.

Each pawl portion of the molding engagement portion thus engaged serves as an undercut stopper for the engaged rail. Yotsutte
As compared with the conventional example that simply relies on the gripping force, a reliable engagement force is maintained between the clip and the belt molding.
