Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip used for mounting automobile parts and the like.

[0002]

2. Description of the Related Art In automobiles, clips are used to attach parts such as decorative materials.

In this type of clip, a leg having a claw is formed below the head, and the leg is inserted into the mounting hole of the body panel from the tip to temporarily bend the claw to pass through the mounting hole. Then, the pawl is restored to its shape after passing through the mounting hole, and is attached to the body panel with the head and the pawl sandwiching the peripheral portion of the mounting hole, and is used for mounting parts to the body panel.

By the way, when an automobile part is attached to a body panel by using a clip, it is necessary to prevent the rust-preventive coating film of the body panel from being damaged. Conventionally, for example, when attaching a weather strip by using a clip. As shown in FIGS. 7 and 8, the clip 10 was used in combination with the cap 12 to attach the weather strip 13 (shown in FIG. 8). The cap 12 is made of a soft resin and is fitted into the leg portion 14 when the leg portion 14 of the clip 10 is inserted into the mounting hole 16, and the insertion of the leg portion 14 into the mounting hole 16 damages the coating film on the inner peripheral wall of the mounting hole 16. This is a configuration that prevents this.

However, when the cap 12 is used as described above, the cap 12 is slid on the leg 14 while the leg 14 of the clip 10 is being inserted into the mounting hole 16, and the cap 12 is removed. Mounting holes 16 for legs 14
It becomes the resistance of insertion into. In particular, since the cap 12 is made of a soft resin, this resistance is large, and even if the pawl 18 restores its shape after passing through the mounting hole 16, the insertion force does not significantly change.
A moderation feeling when attaching the clip 10 is less likely to occur.

Further, since the cap 12 is relatively thick, when the clip 10 is attached to the body panel 22 and a prying force acts on the clip 10 in the direction of arrow F in FIG. Claw 18 is cap 12
There is a possibility that rainwater or the like may enter the inside of the body panel 22 through the mounting holes 16 provided in the body panel 22 because the sheet is easily deformed in the thickness direction and easily disengages from the panel sandwiched state.

[0007]

In consideration of the above facts, the present invention can be attached to a mounting member such as a body panel without damaging the coating film, and can prevent water from entering through the through hole. The purpose is to get a good clip.

[0008]

A clip according to the present invention has a head portion to which a decorative material is attached and abuts on the surface of the attachment member, and a clip extending from the head portion and drilled in the attachment member. A clip composed of a leg portion to be inserted into a through hole, and a pair of elastic locking pieces extending in a direction in which the leg portion is separated from the head portion and connected at a front end portion in the insertion direction, A claw portion which is provided on the elastic locking piece and elastically returns to a diameter after penetrating the through hole and expands the diameter to sandwich the peripheral portion of the through hole between the head portion and the leg portion in the axial direction. Of the claw portion and the elastic locking piece that are integrally continuous to the outer peripheral surface and the inner peripheral surface of the claw portion and the circumferential portion formed of a thin soft resin coating layer, and the circumferential direction is opposite to the inserting direction. The outer end of the side is expanded in the radial direction and elastically adheres between the head and the surface of the mounting member. Is characterized by having a soft flange material that, a.

Further, the soft flange member is formed into an annular shape whose outer end on the opposite side to the insertion direction of the peripheral portion is radially expanded, and the outer peripheral portion thereof extends obliquely toward the surface of the mounting member. As a result, the peripheral portion of the through hole is sealed.

[0010]

In the present invention having the above structure, when the leg portion is inserted into the through hole, the claw portion provided on the elastic locking piece constituting the leg portion is
After penetrating the through hole, it elastically recovers and expands in diameter to clamp the peripheral portion of the through hole between itself and the head, and attach the clip to the attachment member. Thus, when the legs are inserted into the through holes,
Since the peripheral portion formed of the thin-walled soft resin coating layer contacts the inner peripheral wall of the through hole, the coating film on the inner peripheral wall is not damaged. In addition, since the peripheral portion has a thin shape and elastic deformation is small by that amount, there is no fear that the holding state of the mounting member is released even when a twisting force is applied.

At the outer end on the opposite side to the inserting direction of the circling portion,
A soft flange material is provided that is radially expanded.
The soft flange member is interposed between the head and the surface of the mounting member, is sandwiched between the head and the claw portion, and elastically adheres to the mounting member, and has a waterproof effect.

Further, by making the soft flange member annular and extending the outer peripheral portion thereof in an oblique direction toward the surface of the mounting member, it is possible to surround the peripheral portion of the through hole and prevent water from entering through the through hole. It can be prevented.

FIG. 2A is a front view, and FIG. 2B is IIB- in FIG.
2B is an enlarged cross-sectional view taken along line IIB, FIG. 3 is a bottom view of FIG. 2A, FIG. 4 is a top view of FIG. 2A, and FIG.
The left side view of each is shown. Note that FIG. 2 (A)
The right side view and the rear view of FIG. 2A are shown symmetrically with FIGS. 5 and 2A, respectively.

In this embodiment, the clip 30 is attached to a body panel 32, which is an attachment member, as shown in FIG. 6A, and is used to attach a weather strip 34 to the body panel 32. A circular through hole 36 is formed in the body panel 32 for attaching the clip 30. The weather strip 34 is formed of synthetic rubber into a substantially cylindrical shape, and a circular through hole 38 is formed in a mounting portion to the body panel 32 for mounting the clip 30.

A thin disk-shaped head portion 40 is formed on the clip 30, as shown in FIG.

On the upper surface of the head portion 40, a substantially columnar constricted portion 42 is formed coaxially with the head portion 40, and the upper end of the constricted portion 42 has a rectangular plate shape substantially parallel to the head portion 40. The locking portion 44 is formed. The locking portion 44 is obliquely inserted into the through hole 38 of the weather strip 34 from one end side in the longitudinal direction and passes through the through hole 38, and the head portion 40 and the through hole 38.
It is designed so that the peripheral part of the can be pinched.

On the other hand, on the lower surface of the head portion 40, a leg portion 46 extends substantially vertically below the head portion 40 and is inserted into the through hole 36 of the body panel 32 from the tip. The leg portion 46 is formed with a pair of thin-walled elastic locking pieces 48 extending from the head portion 40 in the direction opposite to the locking portion 44.

The pair of elastic locking pieces 48 are substantially semicircular in cross section as shown in FIG. 2, and are opposed to each other with the axial center of the head 40 interposed therebetween. These pair of elastic locking pieces 48
As shown in FIG. 2, the claws 52 are bent in the direction in which they are separated from each other in the middle part in the extension direction, and the claws 52 are formed in the middle part in the extension part of the leg part to partially expand the outer circumference of the leg part. The claws 52 elastically deform the elastic locking pieces 48 toward each other to pass through the through holes 36 of the body panel 32, and after passing through the through holes 36, the elastic locking pieces 48 are restored to their shapes, and Head 40
The peripheral portion of the through hole 36 can be sandwiched between and.

The pair of elastic locking pieces 48 are connected to a small-diameter shaft portion 54 at the tip end portions of the pair of elastic locking pieces 48 in the extending direction approaching each other with the claw 52 as a boundary, and the leg portion 46 with the claw 52 as a boundary. The side has a small diameter to facilitate insertion into the through hole 36.

In the leg portion 46 thus constructed,
As shown in FIG. 6, the outer periphery of the elastic locking piece 48 is formed by secondary molding from the vicinity of the connecting portion of the elastic locking piece 48 to the head 40 to the vicinity of the connecting portion of the elastic locking piece 48 to the shaft 54. Is a thin circumferential portion 55 that is immovable in the axial direction of the leg portion 46, and this circumferential portion 55 is formed with the inner peripheral wall of the through hole 36 when the leg portion 46 is inserted into the through hole 36. It is designed for contact. The head 40 is attached to the orbiting portion 55.
Immediately below the head portion 40, a flange portion 56 made of a soft resin is continuously formed along the lower surface of the head portion 40 so as to protrude in the radial direction more than the head portion 40. The flange portion 56 is brought into contact with the surface of the body panel 32 by inserting the leg portion 46 into the through hole 36 of the body panel 32, so that the body panel 32 and the head portion 4 are joined together.
It is arranged to be interposed between 0 and 0. The flange portion 56 is formed in an annular shape, and the outer peripheral portion thereof extends obliquely toward the body panel 32 and seals the peripheral portion of the through hole 36. The flange portion 56 is formed by secondary molding together with the peripheral portion 55, and is formed separately from the head portion 40 so that it can be flexibly deformed in the direction of arrow A in FIGS. 2 and 5.

Next, the procedure for attaching the weather strip 34 to the body panel 32 using the clip 30 will be described.

First, the clip 3 is attached to the weather strip 34.
Attach 0. The clip 30 is a weather strip 34.
The locking portion 44 is obliquely inserted from the tip into the through hole 38 and is attached to the weather strip 34. The locking portion 44 passes through the through hole 38 and holds the peripheral portion of the through hole 38 with the head portion 40, whereby the clip 30 is attached to the weather strip 34.

Next, the clip 30 is attached to the body panel 32. The leg portion 46 of the clip 30 is inserted into the through hole 36 of the body panel 32 from the tip and is attached to the body panel 32. The leg portion 46 elastically deforms the elastic locking piece 48 and is inserted into the through hole 36 until the pawl 52 passes through the through hole 36. When the leg portion 46 is inserted into the through hole 36, the circumferential portion 55 is prevented from coming into contact with the inner peripheral wall of the through hole 36 and damaging the coating film on the inner peripheral wall of the through hole 36. In addition, the leg portion 46
When the shaft portion 54 is inserted into the through hole 36, the shaft portion 54, the outer periphery of which is not composed of the circumferential portion 55, also passes through the through hole 36, but the shaft portion 54 has a small diameter and does not come into contact with the inner peripheral wall of the through hole 36. Absent.

When the leg portion 46 is inserted into the through hole 36 to this position, the elastic locking piece 48 restores its shape and the inserting force of the leg portion 46 is reduced. Since the circling portion 55 of the leg portion 46 cannot move in the axial direction of the leg portion 46, the circling portion 55 becomes a great resistance to the insertion into the mounting hole 36 when the leg portion 46 is inserted into the through hole 36. When the shape of the elastic locking piece 48 is restored, the force of inserting the leg portion 46 into the through hole 36 is surely greatly reduced, and a sense of moderation is generated when the leg portion 46 is inserted.

When the elastic locking piece 48 restores its shape, the claw 52
Holds the peripheral portion of the through hole 36 with the head 40. At the same time, the flange portion 56 is interposed between the head portion 40 and the body panel 32 to prevent rainwater or the like from entering the inside of the body panel 32 through the through hole 36 between the clip 30 and the body panel 32.

As a result, the clip 30 is attached to the body panel 32 and the weather strip 34 is attached to the body panel 32.

When the clip 30 is attached to the body panel 32 and a twisting force is applied to the clip 30 in the direction of arrow B in FIG. 6A, the circumferential portion 55 is deformed in the thickness direction and one of the claws 52 is fixed to the body panel. It will be displaced in the direction away from the sandwiched state.

However, since the peripheral portion 55 of the elastic locking piece 48 that comes into contact with the inner peripheral wall of the through hole 36 is thin,
Accordingly, the elastic deformation of the orbiting portion 55 is small, the claws 52 do not release the clamped state of the body panel 32, and the attachment strength of the clip 30 to the body panel 32 is large. Further, since the peripheral portion 55 formed on the elastic locking piece 48 is continuously molded integrally with the outer peripheral surface and the inner peripheral surface of the elastic locking piece 48 by the soft resin material, the clip 30 is formed in the pulling direction. Even when a force is applied, the joint surface between the elastic locking piece 48 and the circumferential portion 55 is displaced, and only the elastic locking piece 48 does not come out from the through hole 36.

[0029]

As described above, the present invention does not damage the coating film on the inner peripheral wall of the through hole when the leg portion is inserted. Further, since the circling portion is thin, even if a twisting force is applied, the elastic deformation is small, and there is no risk of releasing the clamped state of the mounting member.

Further, the soft flange material can prevent water from entering through the through hole.
