[Conventional technology]

When attaching a laminate for vehicle interior to a vehicle body panel, for example, the method shown in Figure 5 is used. It has a body part 13 and a head part 14 having upper and lower flanges 11 and 12, and its A clip 1 is used in which a leg portion 16 connected to a head portion 14 is provided with a bulging portion 17 and an umbrella-shaped seat 15. It is used.

0003 That is, as indicated by the arrow in FIG. From the outer diameter of the upper flange 11 of the potbell-shaped fitting hole 36 provided in the substrate layer 33 Insert the upper flange 11 into the insertion hole 37 with a large inner diameter, and connect the upper flange 11 with the facing material 30 of the laminate 34. After inserting it into the interface with the plate layer 33, it is smaller than the outer diameter of the upper and lower flanges 11 and 12. Move it to the locking hole 38 side of the inner diameter, and tighten the circumference of the locking hole 38 between the upper and lower flanges 11 and 12. holding the surrounding substrate layer 33 and then inserting the legs of the clip 1 as indicated by the arrows in FIG. 16 into the through hole 41 of the vehicle body panel 4, and click the bulge 17 and the umbrella-shaped seat 15. By attaching the lip 1 to the vehicle body panel, the laminate 34 is attached to the vehicle body panel 4. This is the way to do it.

[Problem that the idea aims to solve]

However, the interior laminate 34 of the car using the conventional clip 1 as described above is In the mounting method on the body panel 4, it is necessary to provide a potbell-shaped fitting hole 36 in the substrate layer 33. There is. A punch specially manufactured to match the shape of the fitting hole 36 is used to punch the fitting hole 36. had to use.

[0005] Further, between the insertion hole 37 of the fitting hole 36 and the locking hole 38, the upper and lower flaps of the clip 1 are provided. A portion 39 slightly narrower than the outer diameter of the cylindrical body 13 is provided between the flange 11 and 12. , press the body part 13 of the clip 1 into that part 39, and push it into the locking hole 38 side. The clip 1 moves to the insertion hole 37 side again and falls out from the fitting hole 36. However, if the substrate layer 33 is made of a brittle and easily chipped material such as fiberboard, When the narrow part 39 is widened by one passage of the clip 1, the inner part is expanded. When transporting the wearing laminate 34 or when assembling it to the vehicle body panel 4, Clip 1 held on the 34 side often falls off, and its replacement is It was a tedious task.

[0006] Furthermore, a clip is held around the locking hole 38 by its upper and lower flanges 11 and 12. 1 with respect to the through hole 41 of the vehicle body panel 4. The inner diameter of 38 is larger than the outer diameter of the body 13 of the clip 1, so that the body 13 fits inside the locking hole 38. Since it is possible to move freely, the lamination is caused by vibrations of the vehicle and fluctuations in the pressure inside the car when driving at high speed. When the body 34 shakes, an unpleasant sound may be generated.

[0007] The purpose of the present invention is to provide a vehicle clip that eliminates the above-mentioned conventional drawbacks. be.

[0008]

[Means to solve the problem]

The vehicle clip of this invention has a circular fitting hole provided in the base layer of the laminated interior material. The circumference of the head is sandwiched between the circular upper and lower flanges of the head, and the body panel The area around the through hole of the leg is the bulge part of the leg that connects to the head, the umbrella-shaped seat of the leg, or the front of the leg. Attach the laminated interior material to the vehicle body panel by attaching it to the flange below. A clip for a vehicle, which has a cut on the upper flange extending from the center to the periphery in the radial direction. A notch is provided, and the peripheral edge of one of the notches is placed close to the lower flange surface. Therefore, the periphery of the upper flange has a spiral shape that gradually approaches the lower flange side. Because it has the following characteristics, it is possible to solve the problem.

[0009] In other words, there is a notch in the upper flange of the clip that extends radially from its center to the periphery. In addition, one peripheral edge created by the notch should be placed close to the lower flange surface. The spring seat is in contact with the upper flange, and the periphery of the upper flange gradually approaches the lower flange side in a spiral manner. Since the shape is similar to gold, even if the fitting hole is a simple circle, the upper flange can be inserted into the laminated layer. Can be placed at the interface between the substrate layer and cushion layer of the upholstery, and around the fitting hole. The board layer can be strongly compressed between the upper and lower flanges, making it easier for the clip to fit. Eliminates falling off from the joint hole and generation of unpleasant noises due to vibrations, etc.

【Example】

The details of the present invention will be explained with reference to the drawings. Figure 1 shows the vehicle clearing according to the present invention. FIG. 2 is a perspective view showing an example of the top, and FIG. 2 is a front view thereof. The clip 2 is attached to the trunk 13 and a head 24 consisting of upper and lower flanges 21, 12, and legs connected to the head 24. 16, and this leg portion 16 is formed with a bulging portion 17 and an umbrella-shaped seat 15. . Then, between the upper and lower flanges 21 and 12 of the head 24, there is a substrate layer of the laminated interior material 3 (FIG. 4). The bulging portion 1 of the leg portion 16 is sandwiched around the circular fitting hole 35 provided in the leg portion 33. 7 and the umbrella-shaped catch 15 of the leg section around the through hole 41 (Fig. 4) of the vehicle body panel 4. It is something to do.

[0011] As shown in FIG. 1, the upper flange 21 of the clip 2 has a central body 13. A notch 28 is provided which extends in the radial direction from the top to the peripheral edge 29. One end 26 of the peripheral edges 25 and 26 formed by the lower flange 12 side The peripheral edge 29 of the upper flange 21 spirally descends to approach the lower flange. It has a shape that gradually approaches the front side.

0012 As shown in FIG. 3, the laminated interior material 3 includes a skin layer 31, a cushion layer 32, and a substrate. It consists of a layer 33, and a large number of circular fitting holes 35 are provided at predetermined positions in the substrate layer 33. ing. To engage the head 24 of the clip 2 with the fitting hole 35 of the laminated interior material 3, First, attach the bottom of the upper flange 21 of the clip 2 to the side edge of the open surface of the board layer 33 of the fitting hole 35. Place the lowered peripheral edge 26 and push the head 24 of the clip 2 toward the epidermal layer 31. The gap between both peripheral edges 25 and 26 is widened, and the substrate layer 33 and cushion layer 32 are Insert the other undescended peripheral edge 25 into the interface of the clip 2 in FIG. When the clip 2 is rotated once in the clockwise direction when viewed from the side, the peripheral edge 29 is screwed in. As shown in FIG. 4, the periphery 29 of the upper flange 21 The upper and lower flanges 21 and 12 are located at the interface between the substrate layer 33 and the cushion layer 32. The periphery of the fitting hole 35 of the substrate layer 33 is firmly clamped.

[0013] Next, fit the leg portion 16 of the clip 2 into the through hole 41 of the vehicle body panel 4, as shown in FIG. The periphery of the through hole 41 is engaged by the sea urchin bulge portion 17 and the umbrella-shaped seat 15.

[0014] Clip 2 is made of thermoplastic synthetic resin, especially polypropylene, which has high strength and good moldability. Manufactured by injection molding from resin, amide resin, acetal resin, etc. Even if the flange 21 is formed thin, it has sufficient strength, and both peripheral edges 25 , 26 are vertically spaced apart in accordance with the thickness of the substrate layer 33, they will not be damaged. There's nothing to do. In addition, the peripheral edge 29 of the upper flange 21 and the edge of the notch 28 are sharp. Therefore, it can be easily inserted into the interface between the substrate layer 33 and the cushion layer 32.

[0015] One descending peripheral edge 26 and the other peripheral edge of the upper flange 21 of the clip 2 The vertical misalignment difference with the end portion 25 in the free state is approximately 2 of the thickness of the substrate layer 33. 1/3 is preferable, and the peripheral edge 25 for sandwiching the substrate layer 33 is preferably about 1/2. , a large force is required to expand the space between 26 and 26, and if it exceeds 2/3, the upper flap inserted The mismatched unevenness remains on the upper surface of the skin layer 21 without returning, and the unevenness is reversed on the surface of the skin layer 31. This may cause the appearance of the laminated interior material 3 to deteriorate. In addition, the upper flange 21 The appropriate opening of the notch 28 is about 5 to 30 degrees.

[0016] In addition, in order to effectively use the vehicle clip of this invention, it is necessary to The covering material 3 is a laminate consisting of a skin layer 31, a cushion layer 32, and a substrate layer 33. is preferred. In other words, the cushion layer 32 not only provides the inherent flexibility of the interior material, but also Swelling of the skin layer 31 due to the upper flange 21 inserted at the interface with the substrate layer 33 This is because it absorbs moisture and smoothes the surface. However, the epidermal layer 31 is sufficiently thick. If the cushion layer 32 is made of a soft material, the cushion layer 32 can be omitted.

[0017] The clip 2 is rotated with the substrate layer 33 sandwiched between the ends 25 and 26 of the upper flange 21. When doing so, use a wrench that matches the shape of the leg 16 including the bulge 17 of the clip 2. If so, the clip 2 can be easily rotated once. In addition, the substrate layer 3 of the clip 2 3, if it is extremely difficult to insert it into the fitting hole 35, there is a small form a notch, and extend one peripheral edge 25 of the upper flange 21 from the notch. The work becomes easier when you slide it in.

[0018] Furthermore, in the clip 2 of the above embodiment, the bulging portion of the vehicle body panel 4 and its leg portion 16 is 17 and an umbrella-shaped catch 15 on the leg, which is connected to the laminated interior material 3 and the vehicle body panel. The bulging portion 17 is maintained at a constant distance from the lever 4, and the umbrella-shaped catch seat 15 acts as a spring. This is to tighten the vehicle body panel 4 between the The vehicle body panel 4 may be engaged between the flange 12 and the bulge 17.

[0019]

[Effect of the idea]

Since the vehicle clip of this invention is constructed as described above, the board layer is The mating hole provided in place can be a simple circular hole, and the hole is similar to that of a traditional pothole. It is extremely easy to use when compared to the shape of a mating hole, and it can also be Since no large openings are required, there is no need to consider the reduction in strength of the substrate layer due to openings. There's no need.

[0020] In addition, the part of the board layer around the mating hole is strengthened between the upper and lower flanges, which are partially formed narrowly. Because it is tightly compressed, unpleasant noises caused by vibrations, etc. are eliminated, and unlike conventional The clip moves toward the insertion hole like a dowel-shaped fitting hole and comes off from the laminated interior material. It won't fall off.
