Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle side fixing member such as an inner panel of a vehicle such as an automobile, and a roof side inner gear.
This is a clip for assembling parts that is interposed when installing parts such as niches.

[0002]

2. Description of the Related Art Conventionally, when mounting an interior component such as a roof side inner garnish to a vehicle-side fixing member such as an inner panel of a vehicle such as an automobile, a back side of the interior component made of a resin molding is mounted. By projecting ribs and other protruding pieces, fixing the component assembly clip to this rib, and then elastically fitting this clip into the mounting hole formed on the inner panel side It is designed to be attached to the inner panel side.

This component mounting clip is shown in FIG.
As shown in (a) and (b), a flange 101 is provided at the tip of both bent pieces bent in a U shape, a locking claw 102 is cut and raised in the central portion and extended inward, and cut from the base side. The one having a pair of elastic engaging portions 103 that are raised and bulge / bend outwardly is actually an open flat 1-13351.
No. 0 publication and prior art examples in this publication.

Further, as shown in FIGS. 14 (a), (b), and (c), elastic engaging portions 113, 203 are bulged and bent outward on both bent pieces bent in a U shape. The one in which a pair of locking pieces having locking claws 112 and 202 that are cut and raised from the base side and extended inward or outward are formed, respectively, is disclosed in Japanese Utility Model Publication No. 2-88009 and Japanese Utility Model Publication No. 2-762.
No. 11 and No. 61-117908.

Furthermore, as shown in FIG.
A pair of elastic engaging portions 123 that bulge outward and are bent at the base end portions of both bent pieces that are bent in a letter shape, and locking claws 122 that are bent inward and extend at the tips of the elastic engaging portions. What is formed is shown in Japanese Utility Model Laid-Open No. 62-77306.

According to these parts assembling clips, when attaching interior parts such as a roof side inner garnish to a vehicle side fixing member such as an inner panel of a vehicle such as an automobile, as shown in FIG. As shown in a) and (b), a projecting piece such as a rib 16 is provided on the back side of the interior component 15 made of a resin molded body, and the rib 16 is used for assembling a component bent in a U shape. It is inserted into the base of the clip 10 or 20 and the locking claw 102 bites into the side surface of the rib 16 for locking, or the locking hole 16a penetrating the side surface of the rib 16
After engaging and locking the locking claw 202 to the component fixing clip 10 or 20 to the rib 16, the elastic engaging portion 103 or 203 of the clip 10 or 20 is attached to the vehicle side such as an inner panel. By elastically fitting the mounting hole 18 formed in the fixing member 17, the interior component 15
Is attached to a vehicle-side fixing member 17 such as an inner panel. As a result, interior parts such as the roof side inner garnish can be firmly and removably attached to a vehicle-side fixing member such as an inner panel of the vehicle, and thus are widely used.

[0007]

However, these parts-assembling clips require several hundreds to several thousands of them in the production process and the assembling process to interior parts such as the roof side inner garnish. As the unit is randomly placed and stored in one container, for example, in the clip of FIG. 13 (b), the length C of the flange is larger than the gap B formed between the bent pieces as shown in FIG. The flange 101 is enlarged so that the flange 101 cannot enter from the clip side end side. However, as can be seen in FIG. 17, the elastic engagement portion 103 is cut and raised at the center portion and bulges outward, so that the inner size thereof is increased. G is larger than the flange length C. Therefore, in the clip 10 in which the interval S existing at the tips of the pair of locking claws 102 is made larger than the plate thickness t of the clip, the flange 101 at the center of the clip is engaged with other clips as shown by the two-dot chain line in the figure. It enters through the gap S between the tip of the stop claw 102 and the tip of the locking claw 102, and further enters by drawing an arc in the direction of the arrow, resulting in the state of the solid line in the figure. A locking claw 102 in which a flange 101 formed so as not to easily enter various openings of the clip 10 is extended inward in a hook shape.
On the contrary, once passing through, it becomes difficult to exit. Such a state is called "entanglement".

Similarly, in the other conventional clip shown in FIG. 14, a bent piece (which may be an elastic engaging piece or a flange) of another clip intrudes from the gap existing at the tip of the locking claw. In many cases, it becomes entangled. For example,
As shown in FIG. 18, the clip of the type shown in FIG. 14 (b) is bent at one side of the other clip into the base side through the gap at the tip of the locking claw, and the locking claw bends at the other clip. The clips are often entangled with each other because they are caught on one side edge.

When entangled in this manner, it is necessary to unravel the entangled clips before assembling the component-assembling clip to the interior parts, which is extremely complicated and takes a long time. In addition, there is a "part feeder" as a device for arranging clips for assembling parts. This is one in which many clips are put in a mortar-shaped container to vibrate the container, and the clips can be automatically aligned in a certain direction along the guide plate attached to the inner surface of the container and supplied. However, at this time, there is a problem that the component-assembling clips, which are vibrated in the container, are entangled with each other and are caught in the middle of the guide plate, and are clogged.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a clip for assembling parts which is hard to be entangled with each other.

[0011]

In the clip for assembling parts according to the present invention, a plate material having a spring property is bent in a U-shape, and both bent pieces are formed by bending or cutting and bending to be a vehicle-side fixing member. A pair of elastic locking portions that are bulged outward so as to be elastically engageable with the mounting hole that opens, and extend inward or outward from at least one of the bent pieces And a bending piece or a bending piece that opposes the tip of the locking claw and a locking claw formed so as to be locked to the clip mounting projection that is formed to project from the back surface of the interior component. A clip for assembling parts, wherein a gap between the clip and the protruding piece is equal to or smaller than the plate thickness of the clip.

Further, a plate member having a spring property and having bulging portions formed at opposite end sides is bent into a U shape, and both bent pieces are formed by bending or cutting and bending and open to the fixing member. A pair of elastic locking portions that bulge outward so as to be elastically engageable with the mounting hole, and extend inward or outward from at least one of the bent pieces and extend outward. A clip comprising a locking claw formed so as to be capable of locking with respect to a clip mounting projection that is formed to project from a member to be mounted, and a bent piece or a bent piece facing the tip of the locking claw and the tip. A clip for assembling parts, wherein the gap between the protruding piece and the protruding piece is equal to or smaller than the thickness of the bulging portion.

[0013]

In the component mounting clip of the present invention, when the component mounting projection is inserted into the base of the component mounting clip, the locking claw is locked to the projection, and the component mounting projection is mounted on the component mounting clip. Attach the parts assembly clip. In this state, when the component assembly clip and the component mounting projection piece are inserted into the mounting hole of the vehicle side component, the elastic engagement piece engages with the edge portion of the mounting hole of the vehicle side component. Parts can be attached to vehicle-side parts via attachment clips.

Here, in the component-assembling clip of the present invention, the gap between the tip of the locking claw and the bent piece or the protruding piece from the bent piece facing the tip is equal to the plate thickness of the clip or the plate. It is smaller than the thickness. Alternatively, a plate material having bulged portions at both ends is bent in a U shape, and elastic engaging pieces and locking claws are formed on the bent pieces so that the tips of the locking claws are opposed to the tips. The gap between the bent piece or the protruding piece from the bent piece is equal to or smaller than the thickness of the bulging portion.

Since this is done, no part of the bent piece can enter the gap between the tip of the locking claw and the bent piece or the protruding piece from the bent piece that opposes the tip. For this reason, the parts-assembling clips do not become entangled with each other,
There is no need to unravel tangled clips in the assembly process.
Alternatively, the problem of being clogged by being caught in the guide plate in the part feeder is drastically reduced and the production efficiency is remarkably improved.

The feature of the first embodiment is that the minimum gap S between the tip of the locking claw and the tip of the facing locking claw is made smaller than the plate thickness t of the component assembly clip. That is, in FIG. 1, the component mounting clip 1 has a thickness t = 0.5 mm and a width A.
= Bending a plate material such as spring steel of 8 mm into a substantially U shape,
Flanges 11 and 11 projecting outward are formed at both ends of both of the bent pieces, and the center portion in the width direction is cut and raised to project outward, forming a substantially "V" shape, and a free tip is formed. Two pairs of M-shaped tips are formed to form a pair of elastic engaging portions 13 and 13 which are cut and raised further outward in the width direction on the flange 11 side and project inward toward the base side. To form the locking claws 12, 12, 12, 12 of
The minimum gap S between the tip of the locking claw 12 and the opposite tip of the locking claw 12 is 0.4 mm, the distance D from the inner surface of the base to the tip of the locking claw is 10 mm, and the elastic engaging portion 13 is The gap E between the free tip and the flange 11 was set to 0.4 mm. As in the conventional case, the length C of the flange 11 is larger than the gap B existing between the bent pieces.

The use and operation of the above structure will be described with reference to FIGS. 1 and 2. According to the clip 1 for assembling the component, when the interior part 15 such as the roof side inner garnish is attached to the vehicle-side fixing member 17 such as the inner panel of the vehicle such as an automobile as in the conventional case, as shown in FIG. As shown in FIG. 1, ribs 1 are provided on the back side of the interior part 15 made of a resin molded body.

May be made to bite into the rib, or alternatively, the rib 16 may be provided with a lateral hole or the like to be locked in this hole.) After fixing the component assembly clip 1, the elastic engaging portion 13 of this clip 1 is fixed. It is possible to attach the interior component 15 to the vehicle side fixing member 17 such as the inner panel by elastically fitting the to the mounting hole 18 formed in the vehicle side fixing member 17 such as the inner panel.

Further, since the minimum gap S between the tip of the locking claw 12 and the tip of the locking claw 12 which opposes is made smaller than the plate thickness t of the clip 1 for assembling the parts, the gap S of the bent piece The part cannot invade. Therefore, the clip 1 for assembling parts
It will not be entangled with each other. Furthermore, since the gap E between the free tip of the elastic engagement portion 13 and the flange 11 is also smaller than the plate thickness t of the clip for assembling the parts, the flange 11 cannot enter this portion and is not entangled in this portion. ． Although A ≦ D, B ≦ C
Since the free tips of both bent pieces cannot enter the gap B existing between both bent pieces, there is no entanglement from this direction as in the conventional case.

The term "locking claw" used here means a bent piece bent in a substantially U-shape for locking the component mounting clip to the mounting projection of the component from the mounting projection insertion axis line. It refers to those that extend in the direction intersecting with each other and that bite into the mounting projections or that are locked in the locking holes (or grooves) provided in the mounting projections. Therefore, it goes without saying that any clip shape can be applied as long as the gap S present at the tip of the locking claw is equal to or smaller than the plate thickness t of this component mounting clip. That is, in FIG.
Even in the clip for assembling parts having the shapes as shown in FIGS. 4 (b), 4 (a) and 4 (b), if S ≦ t, the same action and effect as described above can be achieved.

[0021]

[Embodiment 2] FIGS. 5 to 6 show a second embodiment of a clip for assembling parts according to the present invention. The same parts as those shown in FIG. 1 or FIG. 2 used in the description of the first embodiment are designated by the same reference numerals, and the duplicated description is omitted here. The feature of the second embodiment is that the bulging portion 6 is formed at the tip of the flange 11 of the component assembly clip of the first embodiment, and the thickness H of the bulging portion is set to the locking claw 12.

The bulge 6 of 1 cannot enter. For this reason, the component-assembling clips 2 do not become entangled with each other. Furthermore, since the gap E between the free tip of the elastic engaging portion and the flange 11 is smaller than the thickness H of the bulging portion 6 as in the first embodiment, the bulging portion 6 of the flange 11 enters this portion. You can no longer get entangled in this part.

The bulging portion 6 has a structure in which, as in the above-described embodiment, the free tip is folded and bulged, as shown in FIG.
As in (c) and (d), the free tip may be bent to form a hollow closed cross-section such as a loop. Further, as shown in FIG. 6B, the free tip may be bent into a U shape so that the opening width is smaller than the clip thickness t. Furthermore, a clip having a thickness larger than the plate thickness may be integrated.

If the engaging claw is provided in the middle of the bent piece (the engaging claw is formed by cutting and bending from the bent piece or by retrofitting), the component assembling clip exists at the tip of the engaging claw. Needless to say, the gap S can be applied to any clip shape as long as it is equal to or smaller than the thickness H of the bulging portion of the component mounting clip. That is, even in the component mounting clip having the shapes shown in FIGS. 6A, 6B, 6C, and 6D, the same action and effect as described above can be achieved if S ≦ H.
