Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a molding clip for attaching a molding as a decorative part to a vehicle body or the like.

2. Description of the Related Art A conventional molding clip has a molding locking portion on its head, a leg or shaft extending downward from the head, and a locking portion at its tip that locks into a vehicle body mounting hole. These molding clips are convenient because they can be easily attached by placing the required number of moldings at appropriate locations on the molding and hammering them into the vehicle body.

Problems to be Solved by the Invention However, since the clip is driven directly into the hole in the vehicle body, the retaining portion of the clip may peel off the coating on the hole in the vehicle body, which is a contributing factor to the occurrence of rust. Also,
When the shape of the molding to be attached changed, a different clip had to be prepared to match it, and a mold for it had to be made.

Therefore, an object of the present invention is to provide a molding clip that does not damage the vehicle body even when hammering is performed, and can be done at a minimum cost even if the shape of the molding changes.

Means for Solving the Problems In order to achieve this purpose, according to the present invention,
A bush that is fixed to a vehicle body, etc., has a shaft, a flange, and a locking pawl on the outer surface of the shaft, and has a hole formed in the axial direction, and a shaft, a head, and a locking shoulder in the hole of the bush shaft. a pin that is fixed to the head of the pin and has a locking pawl formed in two stages spaced apart in the axial direction to lock the button in two stages; A molding clip made of synthetic resin is provided, comprising a holder for holding a holder.

Therefore, since the pin is inserted into the bushing with the holder attached, it will not damage the car body hole, and even if the shape of the molding changes, the bushing can be used as is, and basically all you need to do is replace the holder. The mold cost is also low.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1(a) and 1(b) show the assembled state of the molding clip according to an embodiment of the present invention, in which the molding clip 1 is connected to the pin 2 and the bush 3.
It consists of three parts: and a holder 4, which are made of synthetic resin such as polyacetal, nylon, and polypropylene. In addition, in FIGS. 1(a) and 1(b), the pin 2 is held in a temporarily fixed state with respect to the bush 3.

Figure 2 shows how to attach the car body 5 using the mall clip 1.
This shows how the molding 6 is attached to the pin 2.
is in a permanently fixed state with respect to the bush 3.
In addition, 7 is a rubber body for protection.

3a to 3g show the structure of the bush 3 in detail. The bushing 3 consists of a hollow shaft 11 with a rectangular cross section that fits into a square hole in the vehicle body 5, and a flange 12 extending laterally at the upper part of the shaft. On the shaft 11,
Locking claws 13, 13 protrude outward from corresponding side surfaces
Each pawl is provided with a U-shaped groove 14 that connects to the shaft 11 only at its lower end so as to impart elasticity to the locking pawl 13. As shown in its cross section, the shaft 11 is formed thick to prevent the locking pawl 13 from being broken from the base. A locking shoulder 15 is formed on the inside of the tip of the shaft 11, and is adapted to engage with a locking pawl of the pin shaft.

Pin 2 is shown in detail in Figures 4a-f.
The pin 2 consists of a shaft 21 inserted into the hole 16 of the shaft 11 of the bush 3 and a head 22 above it. axis 2
1, its root is the hole 16 of the bush 3 in cross section.
A first locking pawl 23 is provided at the tip of the shaft to temporarily lock it to the locking shoulder 15 of the bushing shaft 11. Also axis 2
A second locking pawl 24 is formed on the base side of the bushing shaft 11 to permanently lock the shoulder 15 of the bushing shaft 11. The first locking pawl 23 is formed in the shape of an anchor, and is also shown in FIG.
As shown in FIG. 2, the shaft 21 is also tapered toward the tip to improve the ease of inserting the pin. Second locking claw 2
4 is formed on the entire outer periphery of the shaft 21. This second locking pawl 24 is formed by forming a shoulder on the shaft 21, and a side surface 25 on the distal side is inclined so as to taper. On the other hand, the bushing 3 has a complementary slope that is received so that the pin and the bushing are connected without any play on the sloped side surface 29 when the pin 2 is temporarily fixed to the bushing 3, as shown in FIGS. 1a and b. Recesses 17, 17 are formed (FIG. 3f).

A cavity 26 is formed inside the pin shaft 21,
The second locking pawl 24 is given elasticity, and the locking pawls 13, 13 formed on the outer surface of the bushing are designed to easily fall inward when inserted into the mounting hole of the vehicle body 5. . Therefore, when the bush 3 is inserted into a hole in the vehicle body in the temporarily fixed state (FIGS. 1a and 1b), the locking pawls 13, 13 will sandwich it, making the insertion easy. A recess 27 is formed at the base of the shaft 25,
This saves material and reduces weight.

The holder 4 is shown in detail in Figures 5a-e. The holder 4 includes a pin attachment part 31 that receives and fixes the pin head 22, and a molding locking part 3 that protrudes laterally and engages both inwardly bent edges of the molding 6.
2,33. In addition, this molding locking part 3
2 and 33 and the pin attachment portion 31 are reinforced by ribs 34. The pin attachment part 31 includes a base 35 that serves as a seat for the pin head 22 and locking claws 36, 36 that lock on both sides of the pin head 22.
A hole 37 is formed in which the pin shaft 21 passes. Further, slits 38, 38 are formed in the base portion 35 below the locking pawl 36 to facilitate the outward deflection of the locking pawl 36.

In the molding clip 1 constructed as described above, the holder 4 is attached to the pin 2. This is done by inserting the tip of the pin shaft 21 into the hole 37 of the holder 4 and pushing the pin head 22 into the pin attachment part 31 of the holder.By this pushing, the locking claws 36, 36 are once expanded outward. After being moved, it returns to lock the pin head 22. Note that the hole 37 is the pin shaft 2.
1 is preferably the minimum size that can pass through, thereby eliminating play.

The pin 2 and the bush 3 are also connected to each other, but first they are temporarily fastened as shown in FIGS. 1a and 1b. That is, the shaft 21 of the pin 2 is inserted into the hole 16 of the bush 3 and pushed in until the first locking pawl 23 at the tip of the shaft 21 of the pin 2 locks with the inner locking shoulder 15 of the bush 3. As a result, they are temporarily fixed, and the lower inclined side surface 25 of the second locking pawl 24 is brought into close contact with the inclined recess 17 in the bushing shaft, thereby eliminating looseness or play between the pin 2 and the bushing 3. Therefore, in this temporary state, pin 2
is connected to the bushing 3 while maintaining its integrity, and when the holder 4 is attached, it can be delivered to the user in that state, and the holder, pin, and bush can be handled as a set. It is convenient because it can be done. A set of the holder 4, pin 2, and bush 3 is shown in FIGS. 1a and 1b.

In the temporarily fixed state shown in FIGS. 1a and 1b, the temporarily fixed parts 32 and 33 of the holder 4 are slid from the open end of the molding 6 to a predetermined position along the inner bent edge of the molding. Secure the molding in that position by caulking it with a tool, etc. In this way, a plurality of clips 1 are attached to the molding 6 at predetermined intervals.

To attach the molding 6 to which the clip 1 is attached to the vehicle body 5, first place the molding portion to which the clip 1 is attached to the mounting hole of the vehicle body 5 and press lightly. Since the slope 25 of the second locking pawl 24 of the pin 2 is in close contact with the slope 17 of the bush 3, the pin 2 and the bush 3 are temporarily fastened with a considerably strong force, but the outer surface of the bush The locking claws 13, 13
The bushing 3 easily falls inward due to the cavity 26 of the pin shaft, so that the bushing 3 is attached to the vehicle body 5 and temporarily held. In other words, the force of the temporarily fastened pin 2 entering the bush 3 causes the bush 3 to
Since the force with which the pin 2 and the bush 3 enter the hole in the vehicle body is weaker, the pin 2 and the bush 3 remain temporarily attached to the vehicle body.

Next, when the pin 2 is pushed in with a strong force, the second locking pawl 24 locks onto the shoulder 15 of the bushing, resulting in the fully locked state shown in FIG. 2. At this time, the button locking claw 13
The pin shaft 21 is
A solid portion 28 is provided. This results in
The second locking pawl 24 of the pin shaft 21 is connected to the shoulder 1 of the bushing shaft.
5, the pin 2 is fixed to the bush 3 together with the holder 4, and in turn is fixed to the vehicle body 5.
Further, the upper part of the hole 16 in the bush 3 expands outward, and a slope 29 is also formed at the base of the shaft 21 of the pin 2, so that the pin 2 is prevented from entering too much into the bush 3. ing. A rubber body 7 is pushed into the molding 6 as necessary. This rubber body 7 may be integrated with the molding 6 in advance. Usually, a plurality of clips 1 are used in the molding 6. In this case, since the hole 16 of the flange 12 of the bush 3 expands outward, the pin 2 can be easily inserted, improving work efficiency.

FIG. 6 shows another embodiment, in which the pin 2 and the holder 4 are integrally molded. In this case, according to the change in the cross-sectional shape of the molding, it is necessary to prepare and mold not only the holder but also a mold part for the integrally molded pin, but since the pin and holder are integral, it is necessary to In addition to saving the trouble of attaching the holder to the pin, there is also the advantage that the holder will never fall off the pin.

FIG. 7 shows yet another embodiment in which the holder and pin are also integrally molded, but most of the holder portion is absorbed into the pin 2 and becomes the upper extension 4' of the pin. This portion is insert molded into the molding 6' and is integrally fixed to the molding. That is, pins 2 are fixed in advance to appropriate locations on the molding 6', and the operator temporarily fixes the bush 3, and then temporarily holds and permanently fixes it to the vehicle body 5. In addition, pin 2
It goes without saying that the temporary fixing of the bush 3 to the bushing 3 may be done in advance, for example, during the manufacturing of the molding or the manufacturing of the clip.

FIG. 8 shows the pin head of FIG. 7, and the extension portion 4' serving as the holder portion is formed in a rectangular shape.
Further, as shown in FIG. 9, the molding 6' is provided with an embossment (that is, a recess) 8 at the location where the clip is to be attached, and a rectangular hole 9 is formed in this embossment to receive the extension 4'. The extension 4' of the pin 2 is pushed into the hole 9 of the molding and rotated 90 degrees to prevent it from falling out, and then the pin is insert molded so that the molding 6' is coated with resin. As a result, the pin 2 is fixed to the molding 6' as shown in FIG.

In this case, since the pin 2 is attached to the molding 6' first, there is no need to attach the pin (or holder) to the molding, and the pin does not fall off from the molding.

FIG. 10 shows an example in which further improvements were made before insert molding. In this example, the extension 4' has
The cap 40 is attached, thereby eliminating the dent in the embossing 8, thereby eliminating problems such as sink marks during insert molding.

Effects of the present invention According to the present invention, the pin is inserted into a hole in the car body while being temporarily fixed to the bushing, and the bushing is attached to the car body with a small amount of force. There is no need to peel off the film. The pins are inserted into the bushings during final tightening, so they do not damage the car body surface at all. Furthermore, even if the shape of the molding changes, it is basically only necessary to replace the holder, which can be done by simply preparing various holders, and there is no need to replace the entire clip, reducing costs.
