Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fixing clip used for fixing a mounting member such as a door trim of an automobile to a predetermined panel.

[0002]

2. Description of the Related Art As a conventional fixing clip of this kind, there is one disclosed in Japanese Utility Model Laid-Open Publication No. Hei 6-22610. Although not specifically shown, the conventional fixing clip includes three parts of a grommet, a pin, and a seal cap. The first grommet has a flange formed at an upper end edge of the cylindrical body and a lower part of the cylindrical body. A plurality of leg pieces that can be expanded to the side are formed through slits, and the second pin exhibits a rod-like body that is pushed into the cylindrical body of the grommet, and the first pin is arranged in order from the bottom in the vertical direction of the outer peripheral surface thereof. The small-diameter portion, the large-diameter portion, and the second small-diameter portion are formed, and the third seal cap has a tubular bag shape having a flange and a locking shoulder, and has a configuration in which a grommet can be stored therein.

[0003] When fixing a mounting member such as a door trim to a panel using such a three-part fixing clip, a pin is previously pushed into a grommet, and each pin is inserted into a first small diameter portion of the pin. After obtaining a temporary assembly state in which the inward projections protruding from the inner surface of the leg piece are engaged, first, a seal cap is attached to the mounting hole formed on the panel side via the flange and the locking shoulder. This time, while aligning the mouth of the seal cap with the mounting hole formed in the mounting member, the grommet temporarily attaching the pin is housed in the seal cap from the mounting hole of the mounting member. Finally, when the pin is completely pushed into the inside of the grommet, the inward projection of each leg of the grommet engages with the large diameter portion of the pin, and each leg faces outward inside the seal cap. Expand Since, thereby, so that the mounting member is fixed on the panel side.

In the case where it is necessary to remove the mounting member from the panel, when the pin is further pushed into the grommet, the inward projection of each leg of the grommet comes off from the large diameter portion. Since it engages with the second small diameter portion on it and releases the outward expansion of each leg piece, after that, in this state, pinch the flange of the grommet, and from the mounting hole of the mounting member If you pull out with the pin,
The mounting member can be removed from the panel.

[0005]

Therefore, under the conventional fixing clip, the presence of the seal cap has the advantage that the mounting member can be fixed to the panel side while ensuring sufficient watertightness at the fixing point. On the other hand, when the mounting member is removed from the panel, the grommet flange is in close contact with the mounting member surface even if the expansion of each leg of the grommet is released. Therefore, it was not easy to pull out from the mounting hole of the mounting member together with the pin.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a fixing clip according to a first embodiment of the present invention; FIG. As shown in FIG. 1, the number of parts is composed of three parts, that is, a grommet 1, a pin 11, and a seal cap 21.

The first grommet 1 is integrally formed of a synthetic resin to form a flange 3 at the upper end edge of the cylindrical body 2 and a plurality of expandable lower parts of the cylindrical body 2. The leg pieces 4 are formed through the slits 5, and the inward protrusions 6 are integrally formed on the inner surfaces of the distal ends of the leg pieces 4. The second pins 11 are similarly integrally formed of synthetic resin, It has a rod-like body that is pushed into the cylindrical main body 2 of the grommet 1, and forms a first small-diameter portion 12, a large-diameter portion 13, and a second small-diameter portion 14 in the vertical direction of the outer peripheral surface from the bottom, and a third push-up operation The seal cap 21 serving as a means is integrally formed of a synthetic rubber or the like having high elasticity, has a cylindrical bag shape having a flange 22 and a locking shoulder 23, and has a configuration in which the grommet 1 can be stored therein. .

Accordingly, the pin 11 is pushed into the cylindrical main body 2 of the grommet 1 so that the inward projection 6 of each leg 4 is
Grommet 1 and pin 1
When the head 15 of the pin 11 is completely pushed in, the inward projection 6 of each leg 4 is engaged with the large diameter portion 13 and the leg 4 is moved outward. When the head 15 of the pin 11 is pushed into the cylindrical main body 2 again,
The inward projection 6 of each leg piece 4 engages with the second small diameter portion 14 to release the expansion of each leg piece 4. In the first embodiment, in such a state, Tip portion 16 of pin 11
Is set so as to elastically contact the bottom portion 24 of the seal cap 21 and receive a reaction force in the pull-out direction.

Therefore, using the three-part fixing clip, an attachment member P1 such as a door trim is attached to the panel P2.
, First, as shown in FIG.
The seal cap 21 is inserted into the mounting hole H2 formed on the second side.
After being mounted via its flange 22 and locking shoulder 23,
This time, the mouth of the seal cap 21 and the mounting member P1
The grommet 1 to which the pin 11 has been temporarily assembled in advance is accommodated in the inside of the seal cap 21 from the mounting hole H1 of the mounting member P1 while matching the mounting hole H1 formed on the side. When the head 15 of the pin 11 is completely pushed into the interior of the cylindrical body 2 of the grommet 1, the inward projection 6 of each leg 4 of the grommet 1 engages with the large diameter portion 13 of the pin 11 as shown in FIG. At the same time, since each leg 4 expands outward inside the seal cap 21, the mounting member P1 is thereby fixed to the panel P2 side.

If it is necessary to remove the mounting member P1 from the panel P2, the head 1
When the grommet 1 is further pushed into the cylindrical main body 2 of the grommet 1, the inward projection 6 of each leg 4 of the grommet 1
3 and engages with the second small diameter portion 14 thereabove,
The outward expansion of each leg piece 4 is released, but at this time, as shown in FIG. 4, the tip portion 16 of the pin 11 elastically contacts the bottom portion 24 of the seal cap 21 and moves in the pull-out direction. Is received from the seal cap 21, the pin 11 is firstly pushed upward alone.

Then, the pin 11 is pushed upward together with the grommet 1 by the tapered step 17 connected between the second small diameter portion 14 and the large diameter portion 13 abutting on the lower end of each leg piece 4. As a result, as shown in FIG. 5, the flange 3 of the grommet 1 rises from the surface of the mounting member P,
Thereafter, if the raised flange 3 is pinched with a finger and pulled out together with the pin 11 from the mounting hole H1 of the mounting member P1, the mounting member P1 can be very easily removed from the panel P2. In addition, since a pushing force acts on the pin 11, even when the grommet 1 is pulled out together with the pin 11, a small pulling force is sufficient.

As for the seal cap 21, FIG.
As shown in FIG.
If it is thicker, the tip 16 of the pin 11
It does not break easily even when it comes into contact with
Can be easily extended, so that the required rigidity and flexibility as the seal cap 21 can be obtained.

Next, the fixing clip according to the second embodiment will be described. In the second embodiment, as shown in FIG. 7, instead of the seal cap 21 serving as the lifting means in the first embodiment, as shown in FIG. The bottomed storage chamber 31 is integrally formed on the panel P2 side to which the mounting member P1 is fixed, and the return spring 32 serving as a lifting means and the push-up plate 33 are stored in the storage chamber 31 while the first pin 11 The small diameter portion 12 is omitted, and the distal end portion 16 of the large diameter portion 13 is brought into contact with the push-up plate 33.

Therefore, even in the second embodiment,
When the mounting member P1 such as a door trim is fixed to the panel P2, as in the first embodiment, the grommet 1 to which the pins 11 have been temporarily assembled is inserted from the mounting hole H1 of the mounting member P1 into the storage of the panel P2. When the head 15 of the pin 11 is completely pushed into the interior of the cylindrical body 2 of the grommet 1 in a state where the grommet 1 is housed inside the chamber 31, the grommet 1 The inward projection 6 of each leg 4 engages, and each leg 4 expands outward inside the storage chamber 31, whereby the mounting member P1 is fixed to the panel P2 side. . In this case, the pin 11 itself makes the distal end portion 16 of the large-diameter portion 13 elastically contact the push-up plate 33, and the return spring 32
Will receive the reaction force.

When the mounting member P1 is detached from the panel P2, the head 15 of the pin 11 is further pushed into the cylindrical main body 2 of the grommet 1 as in the first embodiment. The inward projection 6 of each leg piece 4 has a large diameter portion 13
8 and engages with the second small-diameter portion 14 thereabove to release the outward expansion of each leg piece 4. At this point, as shown in FIG. While the distal end portion 16 compresses and returns the return spring 32, the push-up plate 33
Therefore, the pin 11 itself receives a large reaction force in the disengagement direction, and firstly, the pin 11 is pushed upward alone.

Then, the pin 11 is pushed upward together with the grommet 1 by the tapered step 17 continuous between the second small diameter portion 14 and the large diameter portion 13 abutting against the lower end of each leg 4. As a result, although not specifically shown,
As in the first embodiment, the flange 3 of the grommet 1 rises from the surface of the mounting member P1. Thereafter, the raised flange 3 is picked up by a finger, and is then taken together with the pin 11 from the mounting hole H1 of the mounting member P1. If pulled out, the mounting member P1
Can be removed from the panel P2 very easily.

Lastly, the fixing clip according to the third embodiment will be described. As shown in FIG. 9, the fixing clip according to the third embodiment has the tip 1 of the pin 11 in the second embodiment.
Elastic body 3 having a pantograph shape as a lifting means to 6
4, while the panel P2 itself only has a mounting hole H2 formed in the same manner as the first embodiment, but the panel P2 itself is formed on the vehicle body inner panel P3 located behind the panel P2. An abutment portion 35 for contacting the elastic body 34 is formed so as to protrude toward the elastic body 34.

Therefore, even in the third embodiment,
When fixing the mounting member P1 such as a door trim to the panel P2, the grommet 1 on which the pins 11 are temporarily assembled in advance is completely pushed into the mounting hole H2 of the panel P2 from the mounting hole H1 of the mounting member P1. As described above, the inward projection 6 of each leg 4 of the grommet 1 is engaged with the large-diameter portion 13 of the pin 11, and each leg 4 expands outward, whereby the mounting member P1 is connected to the panel. It will be fixed to the P2 side. In this case, the tip of the elastic body 34 formed on the pin 11 comes into contact with the contact base 35 of the vehicle body inner panel P3.

When the mounting member P1 is to be removed from the panel P2, the head 15 of the pin 11 is further pushed into the tubular main body 2 of the grommet 1 so that the inward projection 6 of each leg 4 of the grommet 1 is moved. Although it separates from the large-diameter portion 13 and engages with the second small-diameter portion 14 above it, the outward expansion of each leg piece 4 is released. At this point, as shown in FIG. Since the elastic body 34 provided at the distal end portion 16 of the pin 11 deforms and comes into elastic contact with the abutment base 35, the pin 11 itself exerts a reaction force in the removal direction accompanying the deformation of the elastic body 34. In response, first, the pin 11 is independently pushed upward.

Then, similarly, the pin 11 is pushed upward together with the grommet 1 by the tapered step 17 connected between the second small diameter portion 14 and the large diameter portion 13 abutting on the lower end of each leg piece 4. As a result, although not specifically shown,
As in the first embodiment, the flange 3 of the grommet 1 rises from the surface of the mounting member P1. Thereafter, the raised flange 3 is picked up by a finger, and is then taken together with the pin 11 from the mounting hole H1 of the mounting member P1. If pulled out, the mounting member P1
Can be removed from the panel P2 very easily.

[0030]

As described above, according to the present invention, each of the legs of the grommet engages with the small-diameter portion of the pin according to the pushing of the pin, regardless of the configuration, by adopting the above-described structure.
When the outward expansion of each leg is released, the tip of the pin receives a reaction force in the pull-out direction, and this reaction force pushes the pin upward together with the grommet,
Since the flange on the grommet side rises from the surface of the mounting member, the mounting member can be easily removed from the panel only by picking up the raised flange with a finger and pulling it out.
