DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an attachment structure for attaching an automobile part such as a garnish to a member such as a panel via a clip.

[0002]

2. Description of the Related Art As a conventional mounting structure of this kind, an actual fair 6 is used.
No. 49928 discloses. Although not specifically shown, the conventional mounting structure attaches a component such as a garnish having a boss integrally projecting from the back surface to a panel provided with a mounting hole through a U-shaped metal clip. In particular, for the metal clip, both side walls defining the U-shape are bent into a U-shape,
Each of the side walls is formed by cutting out a pair of holding pieces whose front end portions are bent inward.

When attaching a component such as a garnish to a panel, first insert a boss on the component side between the holding pieces of the metal clip, and the bent ends of the holding pieces are engaged with the boss from both sides. Stopping, the metal clip will be assembled to the boss side of the part, but in such a state, the bent end of the holding piece is locked to the boss,
The metal clip and the boss are firmly integrated.

[0004] Then, when the metal clip is pushed into the mounting hole formed in the panel side while maintaining the same state, both side walls are bent inward and pass through the mounting hole. Since the V-shaped portion is elastically locked to the hole edge of the mounting hole, the component can be mounted on the panel side with one touch.

[0005]

Therefore, under the conventional mounting structure, the parts can be mounted on the panel by utilizing the elastic force of the metal clip, so that a correspondingly reliable mounting state is ensured. On the other hand, when the panel is formed of a metal material such as an iron plate, an unpleasant rubbing sound is generated between the mounting hole of the metal panel and the metal clip when the panel is pressed. It was easy to happen.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to a preferred embodiment, in which the mounting structure according to the present embodiment is different from the conventional one, as shown in FIG.
Garnish and other parts 1 with bosses 2 integrally projecting from the back
Is attached to a panel P, which is a member to be mounted, having a mounting hole H formed therein via a U-shaped resin clip 11, but the following configuration is adopted. On the point.

First, for the boss 2 on the part 1 side, FIG.
As shown in the figure, the outer rib walls 3 projecting outwardly over the entire length of both side edges located in the axial direction are formed continuously and integrally, and a fixed distance is provided on both inner surfaces of each of the outer rib walls 3. The two inner rib walls 4 that protrude are formed integrally,
Outer rib wall 3 and inner rib wall 4 which are parallel to each other and have a paired relationship
And a configuration in which the receiving groove 5 is defined between them.
However, as shown in the drawing, the inner rib wall 4 is not formed over the entire length of the boss 2 like the outer rib wall 3, but is formed continuously up to the middle except for the tip side of the boss 2. It is assumed that the tapered shape 4a is positively applied to the leading edge side. Further, the depth of the receiving groove 5 is set so that at least 2/3 of the protrusion described later is filled.

The resin clip 11 is formed of a harder material than the boss 2. For example, when the boss 2 is formed of polypropylene together with the component 1, the resin clip 11 is It shall be molded with polyacetal, and the specific structure is as shown in FIG.
A pair of locking leg pieces 13 having a protruding shoulder 14 at the center of both side walls 12 defining a letter-like shape are provided so as to be able to bend independently via a vertical slit 15, and are divided by the locking leg pieces 13. The upper end edges of both side portions 12a of each side wall 12 are connected by an outward flange 16 having a U-shape, and a similar overhanging shoulder portion is provided at substantially the same position as the overhanging shoulder portion 14 of the locking leg piece 13. 17 and a pair of projections 18 having a triangular shape are formed on both sides of the upper portion of the overhanging shoulder 17 at a certain distance in the thickness direction of both side portions 12a. Configuration. In addition to this, each side wall 1
A tapered cut surface 19 for guiding is formed on the upper inner surface of each of the two side portions 12a so as to face each other.

The paired projections 18 are set so that the interval width L1 is larger than the distance L2 between the outer rib wall 3 and the inner rib wall 4 which are in the paired relationship. Then, the tapered shape 4 of the leading edge of the inner rib wall 4 already described.
In a state in which the guide hole is guided into the receiving groove 5 defined between the outer rib wall 3 and the inner rib wall 4 along the line a, and is pushed into the mounting hole H of the panel P, the tension of the mounting hole H with respect to the inner peripheral surface is obtained. Shoulder 1
7 abuts against the center of the mounting hole H, in other words, toward the receiving groove 5 defined between the outer rib wall 3 and the inner rib wall 4. Also, the protrusion 18 has a tapered shape 18a on the side surface in the mounting direction with respect to the boss 2, that is, on the upper end surface side.
Is positively given. Further, in the present embodiment, only one set of the projections 18 that are in a paired relationship with respect to both side portions 12a is formed, but two or more sets can be formed.

Therefore, when the component 1 such as garnish is mounted on the panel P as a member to be mounted by using the resin clip 11 having the above-described structure, first, as shown in FIG. When the boss 2 is inserted between the side walls 12 of the resin clip 11 with the guidance, the boss 2
Abuts against the bottom of the resin clip 11 while expanding the side walls 12 outward, so that the resin clip 11 is temporarily attached to the boss 2 side of the component 1. The projections 18 which are related to each other are formed between the corresponding outer rib wall 3 and the inner rib wall 4 by using the tapered shape 18a on the upper end surface side thereof and the tapered shape 4a on the tip edge of the inner rib wall 4 as guides. It is guided smoothly into the groove 5.

However, under such a condition, the projections 18 in each pair are guided into the receiving groove 5, but the outer rib wall 3 and the inner rib defining the receiving groove 5. The side of wall 4 is still not fully penetrated.

Then, when the resin clip 11 is pushed into the mounting hole H of the panel P as it is, as shown in FIG. 5, the pair of locking leg pieces 13 attaches its own extending shoulder portion 14 to the mounting hole H. H, while passing through the mounting hole H while being sufficiently bent inward while being in contact with the inner peripheral surface of the mounting hole H, the projecting shoulders 17 of both side portions 12a of the side walls 12 also contact the inner peripheral surface of the mounting hole H. Passing through the mounting hole H while contacting and bending inward,
As shown in FIG. 6, the overhanging shoulders 14 and 17 are elastically engaged with the edge of the mounting hole H of the panel P.
The component 1 is attached to the panel P with one touch.

At this time, the projection 18 on the side portion 12a and the overhanging shoulder portion 17 are separated from each other in the vertical direction at a fixed distance.
The inward bending of 2a is sufficiently promoted, and after passing through the mounting hole H, the springback thereof is made possible, so that the projecting shoulder 17 can be securely locked to the hole edge of the mounting hole H. .

When the side walls 12 of the resin clip 11 pass through the mounting hole H while bending the inwardly protruding shoulders 17 of the both side portions 12a against the inner peripheral surface of the mounting hole H, this time, The projections 18 in each pair are automatically pressed toward the corresponding receiving groove 5 side, and the outer rib wall 3 and the inner rib defining the receiving groove 5 are utilized by utilizing the dimensional difference and the hardness difference. Since the resin clip 11 and the boss 2 of the component 1 are firmly integrated with each other, the rigidity of the resin clip 11 and the boss 2 of the component 1 is ensured.

Therefore, in the present embodiment, it is expected that the resin clip 11 and the boss 2 can be firmly integrated. Therefore, the component 1 is attached to the panel P under the resin clip 11 in the same manner as the metal clip. In addition to being able to stably and reliably mount the panel P, even if the panel P is formed of a metal material such as an iron plate, when the resin clip 11 is pushed into the mounting hole H, the panel P Unpleasant rubbing noise never occurs in relation to the mounting hole H.

When the component 1 is to be removed from the panel P, the resin clip 11 can be pulled out from the mounting hole H of the panel P with the resin clip 11 integrated with the boss 2 side.
The handling is also very good.

The protrusions 18 bite into the side surfaces of the outer rib wall 3 and the inner rib wall 4 so that the protrusion 18 can be sufficiently integrated with the boss 2 at the time of withdrawal. For example, as shown in FIG. By forming a stopper wall portion 20 that abuts on the lower end surface of the projection 18 on the opposing side surfaces of the outer rib wall 3 and the inner rib wall 4 in the relationship described above, the resin clip 11 is used to remove the component 1 from the panel P. The panel can be pulled out from the mounting hole H of the panel P while being more reliably integrated with the boss 2 side.

[0026]

As described above, according to the present invention, according to the first aspect of the present invention, according to the first aspect, the protrusions in the paired relationship on the resin clip side are formed between the rib walls in the paired relationship on the boss side. By using the dimensional difference to forcibly cut in, the resin clip and the boss can be firmly integrated, so even under the resin clip, like the metal clip,
The component can be stably and reliably mounted on the mounting member side, and when the resin clip is pushed into the mounting hole, unpleasant rubbing noise never occurs due to the relation with the mounting hole of the metal panel.

According to the second aspect of the present invention, in addition to this, when the resin clip is assembled on the boss side, it is possible to smoothly guide the projection between the rib walls by utilizing the respective tapered shape. In addition, when the resin clip is pushed into the mounting hole of the member to be mounted, the protrusion is pressed in the center direction of the mounting hole and bites firmly into the side surfaces of the pair of rib walls. It is possible to make it.

According to the fourth aspect, it is possible to promote inward bending of both side walls having the overhanging shoulder, and
The spring back of both side walls is made possible, and the overhanging shoulder portion can be securely locked to the edge of the mounting hole of the member to be mounted. Since the resin clip and the boss are more reliably integrated with each other under the fifth aspect, when the component is detached from the member to be mounted, the mounting hole of the member to be mounted is retained while the resin clip is integrated with the boss. It becomes possible to pull out from.
