Description

The present invention relates to a clip mounting seat for an exterior component or an interior component, and more particularly to a clip mounting seat for an exterior component or an interior component to which a clip can be mounted.

Conventionally, when assembling an exterior part (resin exterior part) such as a rocker molding to a mating member such as a body panel of an automobile, a technique of assembling using a clip is already known. Such a clip is previously mounted in a mounting hole of a clip mounting seat of an exterior component, and by mounting the mounted clip in a mounting hole (not shown) formed in a mating member (not shown). , Exterior parts can be assembled to mating members. Here, Patent Document 1 below discloses a resin member 201 in which a pair of protrusions 228 are formed on the wall surface of the boundary b between the mounting hole 226 of the clip mounting seat 214 and the introduction passage 227 (FIG. 17). ~ 20). As a result, it is possible to prevent the clip 204 mounted in the mounting hole 226 of the clip mounting seat 214 from falling out of the introduction passage 227. Therefore, the holding strength of the attached clip 204 can be increased.

Japanese Unexamined Patent Publication No. 2013-241971

However, in the technique of Patent Document 1 described above, in order to ensure the good mountability of the clip 204 with respect to the mounting hole 226, a wide width w between the pair of protrusions 228 may be formed. In that case, when an unexpected external force f acts on the clip 204 mounted in the mounting hole 226 (see FIG. 21), the clip 204 may fall out of the introduction passage 227 due to the unexpected external force f applied.

The present invention is intended to solve such a problem, and an object of the present invention is to ensure good wearability of a clip, and even if an unexpected external force acts on the mounted clip, the action is unexpected. It is to provide a clip mounting seat that can prevent the clip from coming off due to an external force.

The present invention is intended to achieve the above object, and is configured as follows. The invention according to claim 1 is an exterior component having a peripheral wall that protrudes from the exterior component body or the interior component body and is formed so as to partially open, and a mounting plate that closes the tip of the peripheral wall. Alternatively, it is a clip mounting seat for interior parts. The mounting plate is formed with a mounting hole on which a clip can be mounted and an introduction passage for communicating the opening and the mounting hole. The mounting plate is formed with a pull-out prevention portion that prevents the clip mounted in the mounting hole from falling out of the introduction passage. At least the opening side of the mounting plate from the removal prevention portion faces upward with respect to the mounting plate main body in the direction in which the clip comes off, with the outer component main body or the interior component main body facing upward. It is formed to be inclined.

According to the invention of claim 1, when the clip is attached to the clip attachment seat, for example, one side (for example, the right side) of the base end of the clip attachment body and one side (for example, the right side) of the stabilizer and the clip attachment It interferes with the mounting plate of the seat. This interference causes one-sided friction, and there is one interference portion. Therefore, there is a small frictional force. Therefore, good wearability of the clip can be ensured. On the other hand, when an unexpected external force acts on the clip mounted on the clip mounting seat, for example, the other side (for example, the left side) of the base end of the clip mounting body and the other side (for example, the left side) of the stabilizer and the clip mounting It interferes with the inclined part of the seat. Immediately thereafter, for example, one side (for example, the right side) of the anchor body of the clip interferes with the mounting plate of the clip mounting seat. Both sides of the friction are caused by these interferences, and there are two interference parts. Therefore, a large frictional force exists. Therefore, even if an unexpected external force acts on the clip attached to the clip mounting seat, it is possible to prevent the clip from coming off from the clip mounting seat due to the unexpected external force applied.

Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. 1 to 15. In the following description, "Rocker Mall 1" will be described as an example of "exterior parts". First, the rocker molding 1 and the clip 4 will be described individually.

First, the locker mall 1 will be described first. The rocker molding 1 is a decorative member that is located under a door 3 (for example, a driver's seat door) of an automobile (not shown) and is attached so as to straddle the side surface and the bottom surface of the body panel 2 (FIG. 1). See ~ 2). As is clear from FIG. 2, the rocker molding 1 mainly has an outer member 11 located on the side surface side of the body panel 2 and an inner member 12 located on the bottom surface side of the body panel 2. It is composed of. The outer member 11 and the inner member 12 are connected to each other via an integral hinge 13.

A plurality of clip mounting seats 14 are formed on the inner surface of the outer member 11 (see FIGS. 1 and 2). The clip mounting seat 14 has a substantially U-shaped peripheral wall 20 formed so as to project from the inner surface of the outer member 11 and partially open, and a substantially U-shaped mounting that closes the tip of the peripheral wall 20. It is composed of a plate 25 (see FIGS. 3 to 5). The mounting plate 25 is formed with a long hole-shaped mounting hole 26 to which a clip 4 described later can be mounted, and an introduction passage 27 (guide groove) for communicating the opening 21 and the mounting hole 26.

A pair of protrusions 28 are formed on the wall surface of the boundary B between the mounting hole 26 and the introduction passage 27. The width W between the pair of protrusions 28 is set to be slightly smaller than the outer diameter D of the constricted portion 42 of the clip 4, which will be described later. As a result, as will be described later, it is possible to prevent the clip 4 mounted in the mounting hole 26 from falling out of the introduction passage 27. The protruding portion 28 corresponds to the “removal prevention portion” described in the claims.

Further, the opening 21 side of the mounting plate 25 with respect to the boundary B is formed so as to be inclined upward in the falling direction (opposite direction of the insertion direction) of the clip 4. That is, an inclined portion 29 is formed on the side of the opening 21 side of the boundary B in the mounting plate 25 so as to be inclined upward in the direction in which the clip 4 comes off. The locker mall 1 is configured in this way. The rocker molding 1 configured in this way is integrally molded with a rigid synthetic resin.

Next, the clip 4 will be described. This clip 4 is a known one, and has a bulging mounting body 40, an anchor body 41 having a round shaft-shaped constricted portion 42, and a stabilizer 43 located between the mounting body 40 and the anchor body 41. It is composed of (see FIG. 2). The outer diameter D of the constricted portion 42 is set to be slightly larger than the width length W between the pair of protruding portions 28 of the clip mounting seat 14 described above (see FIG. 6). The clip 4 is configured in this way. The clip 4 configured in this way is integrally molded with a rigid synthetic resin.

Subsequently, a procedure for mounting the clip 4 in the mounting hole 26 of the clip mounting seat 14 of the rocker molding 1 described above will be described (see FIGS. 6 to 13). First, the clip 4 is tilted so that the constricted portion 42 of the clip 4 is located on the substantially extension line C of the tilted portion 29 of the clip mounting seat 14 (see FIGS. 6 to 7). Next, in this tilted state, the work of inserting the constricted portion 42 of the clip 4 into the introduction passage 27 of the clip mounting seat 14 is performed (see FIGS. 8 to 9).

Then, the right side of the base end of the mounting body 40 and the right side of the stabilizer 43 in FIG. 9 interfere with the mounting plate 25 of the clip mounting seat 14. In this way, there is one-sided friction, and there is one interference portion A. Therefore, there will be a small frictional force. Further, when the insertion work is performed, the constricted portion 42 of the clip 4 presses against the pair of protruding portions 28 of the clip mounting seat 14, so that both free end sides of the mounting plate 25 move away from each other (arrows in FIG. 10). It bends in the direction (see FIGS. 10 to 11).

As a result, the constricted portion 42 of the clip 4 gets over the pair of protrusions 28 of the clip mounting seat 14 (the pressing of the pair of protrusions 28 can be avoided), so that the constricted portion 42 of the inserted clip 4 is attached. It reaches the hole 26 (see FIGS. 12 to 13). In this way, the clip 4 can be mounted in the mounting hole 26 of the clip mounting seat 14 of the rocker molding 1. The pair of protrusions 28 can prevent the clip 4 mounted in the mounting hole 26 of the clip mounting seat 14 from falling out of the introduction passage 27, as in the prior art. Therefore, the holding strength of the attached clip 4 can be increased.

Further, when an unexpected external force F acts on the clip 4 mounted in the mounting hole 26 of the clip mounting seat 14 (see FIGS. 14 to 15), the left side of the base end of the mounting body 40 and the left side of the stabilizer 43 in FIG. , Interferes with the inclined portion 29 of the clip mounting seat 14. Immediately after that, the right side of the anchor body 41 in FIG. 15 and the mounting plate 25 of the clip mounting seat 14 interfere with each other. In this way, there is friction on both sides, and there are two interference portions A. Therefore, a large frictional force exists. Therefore, even if an unexpected external force F acts on the clip 4 mounted in the mounting hole 26 of the clip mounting seat 14, it is possible to prevent the clip 4 from falling out of the introduction passage 27 due to the unexpected external force F acting.

On the other hand, as described above, when the clip 4 is mounted in the mounting hole 26 of the clip mounting seat 14, one-sided friction occurs and one interference portion A exists (see FIGS. 8 to 9). Therefore, there is a small frictional force. Therefore, good wearability of the clip 4 can be ensured.

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 the embodiment, "Rocker Mall 1" has been described as an example of "exterior parts". However, the present invention is not limited to this, and as long as it is made of resin, it may be "various exterior parts of an automobile" or "various interior parts of an automobile".

Further, in the embodiment, the locker molding 101 as shown in FIG. 16 may be used. For example, the opening 21 side may be formed so as to be inclined upward from the boundary B in the mounting plate 25 in the falling-out direction (opposite direction of the insertion direction) of the clip 4. That is, an inclined portion 29 may be formed on the opening 21 side starting from the boundary B in the mounting plate 25 so as to incline in the direction in which the clip 4 comes off.

Further, in the embodiment, the protrusion 28 may be a flexible elastic piece.
