Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to an improvement in the fixing structure of a clip for attaching parts.

<Prior art and its problems> For example, as a means of fitting automobile interior parts such as roof garnishes and various pillars into the inner panel of a car, ribs are protruded on the back side of the interior parts made of resin molding. After fixing a steel clip to this rib, the interior parts are attached to the side of the inner panel by elastically fitting the clip into the mounting hole formed on the inner panel side. There is.

Figures 3 and 4 show the fixing structure of conventional component attachment clips. In the drawings, a locking part 3 for attaching and fixing a clip 2 is integrated on the back side of a resin board 1 of an interior component. It is set in. This locking part 3 consists of a pair of guide walls 4, 4, a rib 5 which projects higher than the center of the guide walls 4, 4, and stopper protrusions 6, 6 formed on the sides of the rib 5. It consists of

On the other hand, the clip 2 is made of elastic spring steel or the like and bent into a substantially U-shape, and has locking pieces 2a, 2a bent outward at both ends thereof. Furthermore, elastic fitting pieces 2b, 2b are provided which can be expanded outward by cutting and bulging the central part. These elastic fitting pieces 2b, 2b are connected to the mounting hole 8 of the vehicle body panel 7.
mated to.

By the way, in order to fix the clip 2 to the substrate 1, the clip 2 is inserted from the tip of the locking part 3. That is, the clip 2 is slid to a predetermined position while the rib 5 is held by the spring property of the clip 2 itself.

Note that the guide walls 4, 4 are provided with locking protrusions 4a, 4a on the inside thereof to prevent the clip from falling out.
The clip 2 is prevented from falling off by engaging the locking pieces 2a, 2a of the clip 2 with the locking protrusions 4a, 4a. By the way, the above clip 2
The length of the clip is normally set shorter than the length of the mounting hole 8 provided in the vehicle body panel 7, and is configured to absorb displacement of the clip 2 in the sliding direction.

However, the reality is that no consideration is given to the positional deviation of the clip 2 in the direction perpendicular to the sliding direction of the clip 2 (the width direction of the locking portion).

Therefore, not only is strict molding precision required for the locking portion 3 of the board 1, but also similar precision is required for the mounting holes in the vehicle body panel, which is a mating component. Furthermore, the clip 2 must be accurately positioned and fixed, and if it is attempted to be attached even slightly eccentrically, it will become impossible to attach it to the vehicle body panel.

In addition, the shape of the locking portion 3 formed on the back surface of the resin substrate 1 is complicated, and the mold processing and mold repair of the molding die thereof are troublesome, leading to an increase in costs, which cannot be overlooked.

Moreover, if the clip 2 is securely attached to the locking portion 3, the operation of inserting the clip 2 through the clip 2 becomes difficult, and work efficiency decreases.

On the other hand, to improve work efficiency, clip 1
If the structure is such that the clip 2 can be easily inserted, the clip 2 cannot be held securely, and after the interior parts are attached to the vehicle body panel, the interior parts will rattle due to vibrations while driving, resulting in a poor sense of stability and abnormal noise. There was a problem such as an outbreak.

《Purpose of the invention》 The purpose of this invention is to prevent misalignment of the clip attached to the interior parts in any direction, front, back, left or right.
It is an object of the present invention to provide a fixing structure for a clip for attaching an interior component, which can effectively absorb these positional deviations when attaching to a mating component, has a simple structure, and simultaneously solves problems of ease and reliability in attaching the clip. .

<Configuration and Effects of the Invention> In order to achieve the above object, the present invention includes a base plate that is inserted into a dovetail-shaped guide rail formed on the back surface of an interior component, and a base plate that is erected in the center of the base plate. A clip attachment member having a rib formed to protrude from a guide rail opening, and a clip that is fixed to the rib and connects an interior component to the vehicle body panel by elastically fitting its tip into a mounting hole of the vehicle body panel. A fixing structure for a clip for attaching interior parts, the clip comprising: a mounting part having a pair of locking claws wedged into the rib; and an elastic fitting part integrated into the mounting part. The free end of the mounting portion is bent into a skirt shape to form a pressing piece that presses both edges of the guide rail opening, and has a predetermined gap in the dovetail groove of the guide rail. It is characterized by having a base plate inserted through it.

That is, according to the present invention, since the base plate of the clip attachment member can move in the width direction within the guide rail, the clip fixed to the rib protruding from the base plate can also be finely adjusted in the width direction of the guide rail. It becomes possible to reliably absorb the positional deviation of the clip in the width direction.

Moreover, since both edges of the guide rail opening are constantly pressed by the pressing pieces of the clip, fine adjustments can be made while the clip is held on the guide rail, thereby stabilizing the operation in absorbing positional deviations.

Furthermore, even if the clip is installed in a slightly eccentric state, the clip can be corrected to the appropriate position when fitting the tip of the clip into the mounting hole in the vehicle body panel, and it also has this kind of centering function. ing.

In addition to the conventional method of absorbing misalignment of the clip in the sliding direction of the guide plate, the structure of the present invention can also reliably absorb misalignment of the clip in either the front, back, left or right direction.

In addition, in the present invention, the locking claw of the clip attachment part is fixed to the rib, and the free end of the attachment part is curved into a skirt shape to press and hold both edges of the guide rail opening, so that the attachment is reliable. In addition, the clip can be easily attached by simply inserting the base plate into the dovetail groove of the guide rail while deforming the skirt-shaped pressing piece inward after fixing the clip to the rib of the mounting member. Reliability and ease of installation can be achieved.

Moreover, compared to the conventional shape of the locking part, it has a simpler structure with a dovetail-shaped guide rail and a substantially T-shaped mounting member, which simplifies mold processing and mold repair, and reduces costs. There are also effects that can be achieved.

<Description of Embodiments> Hereinafter, one embodiment of the clip for attaching components according to the present invention will be described in detail with reference to FIGS. 1 and 2. 1st
The figure is a perspective view showing the overall structure, and FIG. 2 is a sectional view showing a state in which interior parts are attached to a vehicle body panel.

In the drawings, reference numeral 11 indicates a substrate for interior parts such as a roof garnish, which is usually molded by injection molding of synthetic resin. A dovetail-shaped guide rail 12 is integrally formed on the back surface 11a of the substrate 11.

The reference numeral 13 indicates a dovetail groove in the guide rail 12, and 14 indicates an opening formed along the center of the upper surface of the guide rail 12.

Reference numeral 15 designates an attachment member for a clip 16, which will be described later, and is composed of a rectangular base plate 17 inserted into the dovetail groove 13, and a rib 18 for attaching the clip protruding from the center of the base plate 17. The clip attachment member 15 is made of synthetic resin and is formed into a substantially T-shaped cross section.

The clip 16 is formed by bending spring steel or the like into a substantially U-shape, and is fixed so as to cover the rib 18.

This clip 16 is comprised of a mounting portion 19 for fixing to the mounting member 15 and an elastic fitting portion 20 that is fitted into a mounting hole 24 of a vehicle body panel 23.

More specifically, the attachment portion 19 has a locking claw 21 cut and raised inward so as to be fixed to the rib 18 of the clip attachment member 15.
1 bites into the rib 18 and its taper is opposite to the direction of removal, thereby performing a removal-preventing action.

Furthermore, the free end side of this mounting portion 19 is curved outward into a skirt shape, and is formed as a pressing piece 22 that constantly presses both edges of the opening 14 of the guide rail 12.

Therefore, in order to attach the clip 16 fixed to the rib 18 by the locking claw 21 to the board 11 on the interior component side, the base plate 17 formed integrally with the rib 18 is inserted into the guide rail 12. . At this time, the pressing piece 2 of the clip 16
The base plate 17 is slid while deforming the base plate 2 inward. And when you reach the desired position,
Since the pressing piece 22 constantly presses both edges of the opening 14 of the guide rail 12, the clip 16 presses against the rib 1.
8 and at the same time held at both edges of the opening 14 of the guide rail 12, a reliable fixing structure is obtained.

The elastic fitting portion 20 is fitted into the mounting hole 24 of the vehicle body panel 23 while being elastically deformed, and when the fitting is completed, the fitting position is regulated by the flange 20a formed at the lower free end. It is becoming more and more common.

In addition, in the present invention, when the groove width of the dovetail groove 13 is a and the width of the base plate 17 is b, a-b=l ₁ is the positional deviation of the clip 16 in the X-axis direction in FIG. Indicates the allowable amount.

Similarly, if the length of the mounting hole 24 provided in the vehicle body panel 23 is c, and the length of the clip 16 is d, then c-d=l ₂ is the allowable displacement of the clip 16 in the Y-axis direction in FIG. shows.
