Abstract

PURPOSE:To suppress increase of insertion load and reduce rickety motion of a clip in a mounting hole when the clip which is used for mounting any mounting part on the surface of the mountbase body is mounted. CONSTITUTION:A central rib 8 which is stretched downward and integrally so that it is positioned between two support poles 5a, 5a from a lower face 4a to a neck section 5 of a flange section 4 with clearance and is cut in the halfway to a drum barrel section 7 is provided, and a side face 8a which almost contacts an inner peripheral face 10a of a mounting hole 10 is formed on the central rib 8. Since the central rib 8 is not connected with the drum barrel section 7, insertion load does not increase. Also, the travel amount of a clip 1 in horizontal direction in the mounting hole 10 is reduced owing to the side face 8a, and rickety motion is reduced.

2. Description of the Related Art Conventionally, as this type of clip, a clip 1 shown in FIG. 6 as a usage diagram is known. This clip 1 is made of integrally molded synthetic resin. The components of this clip are: ■ a flat flange portion 4;
■A neck portion 5 consisting of two pillars 5a, 5a that extend downward at a predetermined distance from the center of the lower surface 4a of the flange portion 4 and can be elastically deformed inward, and is an attachment component (weather strip). The neck portion 5 located in the through hole 9 of No. 2, ■
Shoulder portions 6, 6, which are expanded in diameter outward from the lower free end of each strut 5a, 5a of the neck portion 5, and come into contact with the peripheral edge of the mounting hole 10 on the back surface 3b of the vehicle body (object to be attached) 3; ■Each shoulder 6, 6
The body portion 7 extends downward from the flange portion 4, curves inwardly, and joins together below the center of the flange portion 4, and is elastically deformed inwardly and passed through the attachment hole 10.

[0003] This clip 1 usually has a neck portion 5 inserted into a through hole 9 of an attachment part 2, and in this state is inserted from the body portion 7 into an attachment hole 10 previously provided in an object to be attached 3. After elastic deformation and restoration of the body part 7 and neck part 5, the shoulder parts 6, 6 are fixed to the object to be attached 3 by being locked to the periphery of the mounting hole 10 on the back surface 3b of the object to be attached 3, and the attachment part 2 is fixed to the object to be attached. It is sandwiched and fixed between the lower surface 4a of the flange portion 4 and the surface 3a of the object to be attached 3.

[Problems to be Solved by the Invention] However, in such a conventional clip 1, it is necessary to keep the insertion load to a relatively small value in consideration of the ease of inserting the clip. Hole 10 inner peripheral surface 10a and neck 5
The gap r with the outer peripheral surface is relatively large (for example, about 1.2 mm)
There was a problem in that the clip was likely to wobble in the horizontal direction.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and to provide a clip that can reduce rattling in the horizontal direction without increasing the insertion load.

[0006]

[Means for Solving the Problems] The clip according to the present invention includes a flat flange portion, and two clips that are elastically deformable inward and extend downward at a predetermined distance from the center of the lower surface of the flange portion. The neck part is located in the through hole of the mounting part, and the diameter expands outward from the lower free end of each pillar of the neck part, and the neck part is in contact with the peripheral edge on the back side of the mounting hole of the object to be mounted. a shoulder portion that extends downward from each shoulder portion, curves inwardly and joins with each other below the center of the flange portion, and is elastically deformed inwardly and penetrated through the mounting hole; A clip made of synthetic resin for fixing the attachment part to the object to be attached by sandwiching the attachment part between the lower surface of the flange and the surface of the object to be attached, 2 of the neck from the bottom surface of the flange.
A central rib that integrally extends downward so as to be positioned with a gap between the pillars of the book, and is cut on the way to the body, the central rib having a side surface that substantially contacts the inner circumferential surface of the mounting hole. It is characterized by having ribs.

[0007]

[Operations and Effects of the Invention] In the clip according to the present invention, the central rib extends downward integrally from the lower surface of the flange portion to be positioned with a gap between the two struts of the neck portion, and on the way to the body portion. Since the clip is cut, the central rib does not contribute to the insertion load when the clip is inserted into the mounting hole, and therefore the insertion load is equivalent to the insertion load of the conventional clip described above. Furthermore, since the central rib is formed so that its side surface comes into contact with the inner circumferential surface of the mounting hole, the central rib hardly moves horizontally within the mounting hole. It is possible to reduce the rattling in the

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS.
The explanation will be based on 4 and 5.

The clip 1 of this embodiment has a mounting part 2 (
This is a clip 1 for attaching a weather strip (for example, a weather strip) to a surface 3a of an object to be attached (for example, a vehicle body) 3, and includes a flange portion 4, a neck portion 5, shoulders 6, 6, a body portion 7, and a central rib 8. It is a one-piece synthetic resin (for example, nylon 6) clip.

The flange portion 4 of the clip 1 has a flat plate shape, and when the attachment part 2 is attached to the surface 3a of the object to be attached 3 using the clip 1, the flange portion 4 is attached to the lower surface 4 of the attachment member 3.
a comes into contact with the upper surface 2a of the attachment part 2.

[0011] The neck portion 5 consists of two struts 5a, 5a which extend downward from the center of the lower surface 4a of the flange portion 4 at a predetermined distance and are elastically deformable inward. The neck portion 5 is located within the through hole 9 previously formed in the attachment part 2 when the attachment part 2 is attached to the object to be attached 3 by the clip 1.

[0012] Each shoulder 6, 6 corresponds to each strut 5a, 5 of the neck 5.
The diameter expands outward from the lower free end of a. When the mounting part 2 is attached to the object 3 by the clip 1, the shoulders 6, 6 are attached to the back surface of the object 3 to be attached.
It comes into contact with the peripheral edge of the attachment hole 10 in b, and prevents the clip 1 from coming off.

The body portion 7 extends downward from each shoulder portion 6, 6, curves inwardly, and joins together below the center of the flange portion 4. When the clip 1 is attached to the attachment hole 10 of the object to be attached 3, the body portion 7 is elastically deformed inward so that it can be inserted into the attachment hole 10, and can be restored after penetration.

The central rib 8 extends downward integrally from the lower surface 4a of the flange portion 4 so as to be positioned with a gap between the two struts 5a, 5a of the neck portion 5, and is cut off on the way to the body portion 7. . The central rib 8 is formed with side surfaces 8a, 8a that substantially abut against the inner circumferential surface 10a of the mounting hole 10 when the mounting component 2 is mounted on the object 3 using the clip 1 (see FIG. reference).

Next, a method for attaching the attachment part 2 to the object to be attached 3 using the clip 1 having the above structure will be explained.

■ First, insert the clip 1 into the through hole 9 pre-formed at a predetermined position of the attachment part 2 with the body 7 leading, so that the neck 5 is positioned inside the through hole 9. .

■Next, while applying a pressing force to the flange portion 4 of the clip 1 which has been attached to the attachment part 2 as described above, the clip 1 is inserted into the attachment hole 10 formed in advance in the object to be attached 3. Insert with the body 7 first. During this insertion, the body 7 receives an inward pressing force from the inner circumferential surface 10a of the mounting hole 10, and the two struts 5a, 5a of the body 7 and neck 5 both elastically deform inward and contract in diameter. Accordingly, the torso 7
enters the inside of the mounting hole 10.

Then, when the shoulders 6, 6 pass through the inside of the mounting hole 10, the neck 5 and body 7, which had been reduced in diameter as described above, are restored, and the shoulders 6, 6 are covered. Mounting body 3
It is locked to the peripheral edge of the mounting hole 10 on the back surface 3b,
Even if a pullout load is applied to the clip 1, the clip 1 will not come off from the object 3 to which it is attached.

Therefore, when the clip 1 is attached to the object 3, the attachment part 2 is held between the surface 3a of the object 3 and the lower surface 4a of the flange 4 of the clip 1 (see FIG. 1). ).

In this state after installation, the central rib 8
, the positional relationship between the two pillars 5a, 5a and the mounting hole 10 is as shown in FIG. That is, the side surface 8a of the central rib 8
, 8a and the inner circumferential surface 10a of the mounting hole 10 are in substantially abutting relationship, and the gap r between them is about 0.2 mm or less. Therefore, the amount by which the central rib 8 moves in the horizontal direction within the attachment hole 10 is small, thereby reducing the wobbling of the neck portion 5 in the horizontal direction.

As explained above, in the clip 1 of this embodiment, the central rib 8 extends downward from the lower surface 4a of the flange portion 4 to be positioned with a gap between the two struts 5a, 5a of the neck portion 5. Since it extends integrally and is broken on the way to the body 7, the central rib 8 does not contribute to the insertion load when inserting the clip 1 into the mounting hole 10, and therefore the insertion load is lower than that of the conventional clip 1 described above. It is equivalent to the insertion load of Furthermore, since the central rib 8 is formed so that its side surfaces 8a, 8a are almost in contact with the inner circumferential surface 10a of the mounting hole 10, the central rib 8 can hardly move in the horizontal direction within the mounting hole 10. Therefore, the backlash of the neck portion 5 within the mounting hole 10 can be reduced.
