However, in the technique of Patent Document 1 described above, when a molding defect occurs in the resin molded product 312 (for example, a molding defect occurs such that the edge of the molded resin molded product 312 is formed longer than that in the design drawing). The edge of the resin molded product 312 attached to the panel material 311 strongly interferes with peripheral members (for example, outer panel, inner panel (panel material 311), vehicle body, etc.). there were. When such strong interference occurs, a reaction force may act on the attached resin molded product 312 from the peripheral member. Therefore, a pull-out load may always act on the clip 302 used for this attachment. Therefore, the leg member 320 of the clip 302 may be half-engaged (half-engaged) with respect to the mounting hole 311a of the panel material 311 (see FIG. 17). As a result, the attached resin molded product 312 may come off from the panel material 311.

The present invention is intended to solve such a problem, and an object of the present invention is to perform this attached resin molding even when a resin molded product attached to a panel material using a clip strongly interferes with a peripheral member.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
(Example 1)
First, Example 1 of the present invention will be described with reference to FIGS. 1 to 6. First, the door 1 and the clip 2 of the automobile (not shown) according to the first embodiment will be described individually.

First, the car door 1 will be explained first. As shown in FIG. 1, the door 1 is, for example, on the driver's side of a right-hand drive vehicle, and is configured by overlapping the outer panel 10 and the inner panel 11. A plurality of mounting holes 11a for mounting the door trim 12 which is a resin molded product are formed at appropriate positions on the inner panel 11 (see FIG. 2).

The door trim 12 is composed of a panel-shaped door trim main body 13 and a plurality of mounting seats 14 formed at appropriate positions on the anti-design surface side edge of the door trim main body 13. An armrest 13a and an inside handle 13b are attached to the design surface side of the door trim body 13. As shown in FIG. 2, the mounting seat 14 is composed of a wall portion 14a that rises in a U shape from the counter-design surface side of the door trim main body 13, and a seat portion 14b that closes the tip of the wall portion 14a. A circular mounting hole 15 is formed in the seat portion 14b.

Since the door trim 12 is attached to the inner panel 11, the mounting holes 15 of the plurality of mounting seats 14 in the door trim 12 coincide with each other with respect to the plurality of mounting holes 11a in the inner panel 11. It is set to do. A notch 16 is formed on the side of the seat portion 14b where the wall portion 14a does not exist. The notch 16 is shaped to be connected to a part of the mounting hole 15. As a result, the neck body 26 of the clip 2, which will be described later, can be inserted toward the mounting hole 15 through the notch 16. The door 1 is configured in this way.

Next, the clip 2 will be described. As shown in FIGS. 3 to 4, the clip 2 is integrated with the leg member 20 having a constriction 20a that can be attached to the mounting hole 11a formed in the inner panel 11 and the leg member 20. It is composed of a mounting member 21 that can be mounted in the mounting hole 15 formed in the mounting seat 14 of the door trim 12. A dish-shaped stabilizer 27 having an elastic action is formed on the base end side (mounting member 21 side) of the leg member 20. Thereby, the difference in the plate thickness of the inner panel 11 can be absorbed.

Here, the mounting member 21 will be described in detail. The mounting member 21 bridges the pair of circular brims 22 and 25 so that the axes of the pair of brims 22 and 25 coincide with each other. It is composed of a columnar neck body 26 having a diameter smaller than both outer diameters of the pair of collar bodies 22 and 25. Of the pair of collar bodies 22 and 25, the one located on the outer side (opposite side to the leg member 20) in the axial direction is referred to as the first collar body 22. On the contrary, of the pair of brim pieces 22 and 25, the one located on the inner side (the same side with respect to the leg member 20) in the axial direction is referred to as the second brim body 25.

The first flange body 22 is strong and has sufficient strength so that the mounting member 21 mounted in the mounting hole 15 of the door trim 12 does not come off. The first flange body 22 can absorb the reaction force acting on the door trim 12 attached to the inner panel 11 from the peripheral members (for example, the outer panel 10, the inner panel 11, the vehicle body, etc.) as described later. Elastic piece 23 is formed in a dish shape. The elastic piece 23 is formed from an intermediate portion in the radial direction of the first collar body 22 (see FIG. 4).

Therefore, the outer diameter of the elastic piece 23 is made compact as compared with the form in which the elastic piece 23 is formed from the outer edge in the radial direction of the first flange body 22 (clip 102 of the second embodiment described later). it can. That is, assuming that the outer diameter of the elastic piece 23 of the clip 2 in the first embodiment is "D1" (see FIG. 4), and the outer diameter of the elastic piece 123 of the clip 102 in the second embodiment described later is "D2" (FIG. 4). 8), the relationship of "D1" <"D2" is established. Further, the distance between the tip of the elastic piece 23 and the second flange body 25 is set to be equal to or slightly narrower than the plate thickness of the seat portion 14b of the mounting seat 14 of the door trim 12.

Further, on the edge on the tip end side of the elastic piece 23, a rebound portion 23a that warps toward the first collar 22 side is formed. Therefore, when the work of inserting the neck body 26 of the clip 2 into the notch 16 of the mounting seat 14 of the door trim 12, the elastic piece 23 can be prevented from being caught in the neck body 26 side. Therefore, the guideability of this insertion work can be improved.

Further, on the outer edge of the first collar body 22, ridges 24 that bulge toward the leg member 20 side are formed in a pair. Therefore, it is possible to prevent the elastic piece 23 from being excessively warped. The leg member 20 and the mounting member 21 are integrally molded of a rigid synthetic resin so that their axes are aligned with each other. The clip 2 is configured in this way.

Subsequently, a procedure for attaching the door trim 12 to the inner panel 11 of the door 1 of the automobile by using the clip 2 described above will be described. First, while holding the clip 2, the work of inserting the neck body 26 of the clip 2 into the notch 16 of the mounting seat 14 of the door trim 12 is performed. Then, as described above, the distance between the tip of the elastic piece 23 and the second flange body 25 is set to be slightly narrower than the plate thickness of the seat portion 14b of the mounting seat 14 of the door trim 12, so that the neck is set. The elastic piece 23 of the clip 2 into which the body 26 is inserted and the second flange body 25 sandwich both sides of the seat portion 14b of the mounting seat 14.

As a result, the neck body 26 of the clip 2 can be inserted into the notch 16 of the mounting seat 14 of the door trim 12 without causing rattling. Further, the work of inserting the neck body 26 of the clip 2 is performed, and when the neck body 26 of the inserted clip 2 reaches the mounting hole 15, the door trim 12 is mounted on the mounting seat 14 of the mounting hole 15. The mounting of the member 21 is completed. That is, the attachment of the clip 2 to the door trim 12 is completed. The clip 2 is mounted in all the mounting holes 15 of the plurality of mounting seats 14 of the door trim 12.

Next, the work of aligning the door trim 12 to which the clip 2 is attached with respect to the inner panel 11 is performed. As a result, the axes of the plurality of mounting holes 11a of the inner panel 11 and the respective mounting holes 15 of the plurality of mounting seats 14 of the door trim 12 are aligned with each other. That is, the axes of the plurality of mounting holes 11a of the inner panel 11 and the respective clips 2 mounted in the respective mounting holes 15 of the plurality of mounting seats 14 of the door trim 12 coincide with each other. Next, the leg member 20 of the clip 2 mounted on the door trim 12 is inserted into the mounting hole 11a of the inner panel 11.

Then, the leg member 20 of the clip 2 is press-fitted into the mounting hole 11a while elastically deforming in the direction in which the leg member 20 itself contracts. Further, the work of inserting the leg member 20 of the clip 2 is performed, and when the constriction 20a of the leg member 20 of the inserted clip 2 reaches the mounting hole 11a, the leg member 20 is elastically deformed in the contraction direction. Is returned, and the attachment of the leg member 20 to the mounting hole 11a of the inner panel 11 is completed, and the stabilizer 27 comes into close contact with the inner panel 11.

That is, the engagement of the clip 2 with the inner panel 11 is completed. The engagement of the clip 2 is performed in all of the plurality of mounting holes 11a of the inner panel 11. Therefore, when the engagement of the clip 2 is completed, the clip 2 is attached to the door trim 12 as described above, so that the door trim 12 is attached to the inner panel 11 (see FIG. 5). ). In this way, the door trim 12 can be attached to the inner panel 11 using the plurality of clips 2.

As in the prior art, due to molding defects caused in the door trim 12, the edges of the door trim 12 attached to the inner panel 11 are peripheral members (for example, outer panel 10, inner panel 11, vehicle body (not shown), etc. ), A reaction force acts on the attached door trim 12 from the peripheral member. Then, the elastic piece 23 of the mounting member 21 of the clip 2 is warped by this acting reaction force and becomes a substantially flat state (see FIG. 6). That is, the elastic piece 23 absorbs (relaxes) this acting reaction force.

Therefore, even if a reaction force acts on the attached door trim 12 from the peripheral member, the pull-out load on the clip 2 used for the attachment is reduced. Therefore, the leg member 20 is not half-engaged (half-engaged) with respect to the mounting hole 11a of the inner panel 11. As a result, the attached door trim 12 does not come off from the inner panel 11.

(Example 2)
Next, Example 2 of the present invention will be described with reference to FIGS. 7-10. The clip 102 of the second embodiment is more compact in the height direction than the clip 2 of the first embodiment described above. In the following description, the members having the same or the same configuration as the members described in the first embodiment will be designated by the same reference numerals in the drawings, and duplicate description will be omitted. This also applies to the modification 1 described later.

Similarly to the clip 2 of the first embodiment described above, the clip 102 of the second embodiment also has a leg member 20 having a constriction 20a that can be attached to the mounting hole 11a formed in the inner panel 11 and the leg member. It is integrated with 20 and is composed of a mounting member 21 that can be mounted in the mounting hole 15 formed in the mounting seat 14 of the door trim 12 (see FIG. 7).

In the clip 102 of the second embodiment, unlike the elastic piece 23 of the first embodiment, the elastic piece 123 is formed in a dish shape from the outer edge in the radial direction of the first collar body 22 (FIG. 8). Therefore, in the clip 102 of the second embodiment, unlike the clip 2 of the first embodiment, the first flange body 22 and the elastic piece 23 do not overlap each other in the height direction. Therefore, as compared with the clip 2 of the first embodiment, it can be made more compact in the height direction.

Further, the outer diameter of the elastic piece 123 is formed to be larger than the outer diameter of the stabilizer 27. Therefore, when the clip 2 is attached to the door trim 12, when the neck body 26 of the clip 2 is inserted into the notch 16 of the mounting seat 14 of the door trim 12, the elastic piece 123 is covered by the seat portion 14b of the mounting seat 14. I will go. Therefore, it can be easily confirmed visually that the clip 102 has been attached.

Further, also in this Example 2, the same action and effect as in Example 1 can be obtained. That is, also in the second embodiment, the door trim 12 can be attached to the inner panel 11 by using the plurality of clips 102 (see FIG. 9).

Further, also in the second embodiment, when a reaction force is applied from the peripheral member to the door trim 12 attached to the inner panel 11 by using the plurality of clips 102, the reaction force applied to the attachment member 21 of the clip 102. The elastic piece 123 bends back and becomes a substantially flat state (see FIG. 10). That is, the elastic piece 123 absorbs (relaxes) this acting reaction force. Therefore, even if a reaction force acts on the attached door trim 12 from the peripheral member, the pull-out load on the clip 102 used for the attachment is reduced. Therefore, the leg member 20 is not half-engaged (half-engaged) with respect to the mounting hole 11a of the inner panel 11. As a result, the attached door trim 12 does not come off from the inner panel 11.

The above-mentioned contents are merely related to one embodiment of the present invention, and do not mean that the present invention is limited to the above-mentioned contents.

In each embodiment, the "inner panel 11" has been described as an example of the "panel material". However, the present invention is not limited to this, and may be a "thin plate portion in the body of an automobile" or the like. Moreover, in each Example, "door trim 12" was described as an example of "resin molded article". However, the present invention is not limited to this, and may be an "overhead console", a "center cluster", or the like.

Moreover, in each Example, the form in which elastic pieces 23 and 123 are formed in a dish shape was described. However, the present invention is not limited to this, and the elastic pieces 23 and 123 may be formed in the shape of a pair of feathers or a pair of wings.

Further, in Example 1, the elastic piece 23 has been described as a clip 2 formed from an intermediate portion in the radial direction of the first collar body 22. However, the present invention is not limited to this, and the elastic piece 23 may be formed from a portion of the first brim 22 near the base of the neck body 26 as shown in FIGS. 11 to 13. Example 1). Of course, the present invention is not limited to this, and the elastic piece 23 may be formed from a portion of the first collar body 22 near the base of the neck body 26 and a portion straddling the neck body 26. .. In addition, in this modification 1, the same action and effect as in Example 1 can be obtained. That is, also in this modification 1, the door trim 12 can be attached to the inner panel 11 by using a plurality of clips 202 (see FIG. 13).
