Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a molding for a vehicle made of synthetic resin, and particularly to a long molding for a vehicle having a clip for attachment to a vehicle body.

[Prior art]

BACKGROUND OF THE INVENTION Long synthetic resin moldings having a desired decorative outer surface and a substantially flat back mounting surface are used in side moldings and fender moldings for vehicles. This type of molding is attached using a clip that has a locking part that engages with a mounting hole provided in the vehicle body panel, but in order to secure the clip to the molding body, the base of the clip is shaped like a disk. It is then fixed by spin welding.

However, in such conventional synthetic resin moldings, if the top surface of the welded board is higher than the mounting surface, it becomes difficult to securely attach the molding to the vehicle body, and positioning during spin welding becomes difficult. Therefore, it is necessary to provide a circular counterbore on the mounting surface of the molding body, and rotate the clip while fitting the disc-shaped base of the clip into this, resulting in the problem that forming the counterbore is time-consuming. It was hot.

[Purpose of invention]

This idea was developed to solve the above problems by welding the base of the clip to the mounting surface of the molding body and attaching double-sided adhesive tape with cushioning properties to both sides of the base, thereby eliminating the counterbore. To provide a synthetic resin molding that does not need to be formed, absorbs variations in height of a welded base, and can be reliably attached to a vehicle body.

[Structure of the idea]

This invention consists of a molding body having a substantially flat mounting surface, and a clip having a locking portion that protrudes from approximately the center of the base fixedly welded to the mounting surface and engages with a mounting hole in a vehicle body panel. , a double-sided adhesive tape having cushioning properties in which an adhesive layer is formed on both sides of a cushion material and is affixed to the mounting surfaces on both sides of the base, and the normal thickness of the double-sided adhesive tape is the same as the mounting surface of the base. This is a synthetic resin molding characterized by being set to be the same or slightly thicker than the dimension from the surface to the clip's locking part minus the thickness of the vehicle body panel.

[Example of idea]

This invention will be explained below with reference to embodiments of the drawings. Figures 1 to 5 show one embodiment of this invention, with Figure 1 being a front view of the clip, Figure 2 being a side view thereof, and Figures 3 and 4 showing the mold during installation. FIG. 5 is a cross-sectional view of the deing, showing the state after installation.

The molding body 1 is formed into a long length using a thermoplastic resin such as ABS resin or PVC resin, and its outer surface is a decorative surface 2 having a desired shape, and its back surface is a substantially flat mounting surface 3. Reference numeral 4 denotes a decorative film such as a bright film or a colored film, which is embedded in the decorative surface 2 so that a portion thereof is exposed.

The clip 5 includes a disk-shaped base 6 welded to the mounting surface 3, a leg 7 projecting perpendicularly from approximately the center of the base 6, a locking portion 8 formed on the leg, and a peripheral edge of the base 6. It has a protrusion 9 formed in the part, and the protrusion 9 is removed when spin welding is performed. Further, on the back surface of the base 6, a conical protrusion 10 is formed in the center and an annular protrusion 11 is formed around the conical protrusion 10, both of which have pointed tips. Note that the height of the conical projection 10 is desirably set to exceed the height of the annular projection 11. Reference numeral 12 denotes a double-sided adhesive tape having cushioning properties that is adhered to the mounting surfaces 3 on both sides of the base 6, and an adhesive layer 14 is formed on both sides of a cushion material 13 such as a sponge. Reference numeral 15 designates a vehicle body panel serving as an attached part, and has an attachment hole 16. The normal thickness of the double-sided adhesive tape 12 is the same as the dimension from the attachment surface 3 to the tip of the locking part 8 of the clip 5 minus the thickness of the vehicle body panel 15, or is slightly thicker.

In the above configuration, the convex part 9 of the clip 5 is hooked on the jig, and the back surface of the base 6 is opposed to the mounting surface of the molding body 1 while rotating the base 6 in the direction A as shown in FIG. When the protrusions 10 and 11 are pressed in the direction B, the protrusions 10 and 11 bite into the mounting surface 3 and are positioned as shown in FIG. is welded with a part buried in the molding body 1, and at the same time, the convex part 9 softens and separates, the jig rotates idly, and the clip 5 is fixed to the molding body 1. With the clip 5 fixed in this way, double-sided adhesive tape 1 is attached to both sides of the base 6.
2 is attached to complete the molding.

In the above molding, as shown in FIG. 15 and attach it. In the installed state, even if the height of the base 6 varies, the double-sided adhesive tape 1
The cushioning properties of No. 2 absorb this variation. Furthermore, even if burrs 17 are formed during welding, they can be stored within the height of the double-sided adhesive tape 12, and the molding can be reliably fixed to the body panel 15.
It can be installed on any surface without wobbling or falling off.

The normal thickness F of the double-sided adhesive tape 12 is F, where t is the thickness of the base 6, h is the height from the base 6 to the tip of the locking part 8, and d is the thickness of the vehicle body panel 15. = (t+h-d-0.1) or (t+h-d
-0.5) millimeters is preferred. Further, when a protruding part 19 is formed on both side edges of the molding body 1 so as to protrude from the mounting surface 3 side so as to come into contact with the vehicle body panel 15 so as to form an internal space 18, the molding body 1 and the vehicle body panel 1
There is no gap between 5.

FIG. 6 is an exploded sectional view of a clip showing another embodiment, in which the clip 5 consists of a first clip 5a and a second clip 5b attached thereto. The first clip 5a has two legs 7 that elastically protrude vertically from the center of a disc-shaped base 6, a locking part 8 formed on both sides of the tip of the legs 7, and a pair of legs 7. A stopper 20 formed at the base of the portion 7
has.

The second clip 5b is made of elastic synthetic resin like the first clip 5a, and includes a bell-shaped skirt portion 21, a hollow portion 22 into which the leg portion 7 is inserted, and a hollow portion 22 into which the leg portion 7 is inserted.
A groove portion 23 into which the locking portion 8 is inserted, an engaging portion 24 that engages with the locking portion 8, and a locking portion formed around the entire circumference of the tip of the skirt portion 21 so as to engage with the mounting hole 16 of the vehicle body panel 15. It is formed to have a stop portion 25 and an engaging portion 26 that engages with the stopper 20.

In the above configuration, when the second clip 5b is attached in the direction C to the first clip 5a to which the base 6 is spin-welded to the molding main body 1 in the same manner as described above, the leg 7 is inserted into the hollow part 22, The locking part 8 is inserted into the groove part 23 and engages with the engaging part 24,
The stopper 20 engages with the engaging portion 24, and the second clip 5b is locked to the tip of the first clip 5a.

The molding constructed as described above is attached by inserting the clip 5 into the attachment hole 16 of the vehicle body panel 15 and engaging it. In this case, since the locking portion 25 of the second clip 5b is formed over the entire circumference, it can be attached to either the round or oblong mounting hole 16 regardless of the stopping position of the first clip 5a. It also engages.

In the above description, the shape, structure, material, etc. of the molding body 1 and the clip 5 can be changed. This invention can also be applied to side moldings, fender moldings, and other vehicle moldings. Further, the double-sided adhesive tape 12 is not limited to being attached only to both sides of the base 6 of the clip 5, but may be attached so as to surround the base 6.
