Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a component fixing clip, and more particularly to a component fixing clip used for fixing a mounting component such as an emblem to an outer panel of an automobile.

[0002]

[Prior art]

 When attaching an emblem or the like to the outer panel of an automobile, a clip for fixing parts made of synthetic resin such as nylon is generally used. The component fixing clip is fitted into the through hole-shaped clip mounting hole formed in the outer panel which is the component fixing member, and the emblem is inserted into the locking leg insertion hole formed in the component fixing clip. The mounting component is fixed to the component fixing member by inserting the locking leg protruding from the back side of the mounting component.

As a component fixing clip used for this fixing, there is known a bush-like clip as disclosed in Japanese Utility Model Publication No. 53-225094 and Japanese Utility Model Publication No. 61-97605. However, in both cases, the locking leg insertion hole is formed by a through hole that axially penetrates the component fixing clip.

[0004]

[Problems to be solved by the device]

 In the component fastening clip as described above, even if the locking leg insertion hole is formed by the through hole that penetrates the component fastening clip in the axial direction, the locking leg insertion hole is By inserting the locking leg part of this, it will be blocked by this locking leg part. Therefore, by design, rainwater etc. should intrude through the locking leg insertion hole into the inside of the component fixing member such as the outer panel. There is no. However, in reality, there is a dimensional error in the manufacturing of the locking leg insertion hole and the locking leg, or the deformation and material of the fitting part between the locking leg insertion hole and the locking leg due to long-term use. As a result, the fine gap may occur between the locking leg insertion hole and the locking leg. Therefore, it is conceivable that rainwater or the like may enter the inside of the component fixing member through this minute gap. This phenomenon is likely to occur at the mounting part such as an emblem on the outer panel of the vehicle, which may cause the waterproof property inside the vehicle body to be impaired or cause rusting of the outer panel.

The present invention has been made by paying attention to the problems in such a conventional component fixing clip, and its main purpose is to provide a locking leg insertion hole and a locking leg. Due to manufacturing dimensional error, deformation of mating part between locking leg insertion hole and locking leg due to long-term use, deterioration of material, etc., locking leg insertion hole and locking leg It is intended to provide a component fixing clip that can reliably ensure waterproofness even if a minute gap occurs between the component and the clip.

[0006]

[Means for Solving the Problems]

 According to the present invention, such an object is to be inserted into the clip mounting hole formed in the component fixing member in an externally fitted state, and the locking leg portion of the mounting component is inserted into the locking leg insertion hole. The structure of the component-fixing clip for fixing the mounting component to the component-fixing member by being inserted is described below. An inner cylindrical body portion that is arranged with a predetermined annular space in between and is connected to the outer cylindrical body portion at one end to define a locking leg insertion hole inside thereof, and a tip of the locking leg insertion hole. It is achieved by having a cap-shaped portion integrally formed with the inner cylindrical portion to close the side.

[0007]

[Action]

 By doing so, the cap-shaped portion makes the locking leg insertion hole a bottomed hole, and even if water enters the locking leg insertion hole, it will be the tip side of the locking leg insertion hole. Never leaks out.

[0008]

Embodiments The present invention will be described in detail below with reference to the accompanying drawings.

1 to 4 show an embodiment of a component fastening clip constructed according to the present invention. In these figures, the component fastening clip is generally designated by the reference numeral 1, which is entirely constructed of a synthetic resin material having an appropriate elasticity such as nylon.

The component fastening clip 1 is arranged with an outer tubular body portion 3 and a predetermined annular gap 5 inside the outer tubular body portion 3, and the outer tubular body portion 3 is connected by a connecting portion 7 at one end thereof. And an inner cylindrical body portion 9 connected to the inner cylindrical body portion 9 are concentric with each other, and a locking leg insertion hole 11 is defined inside the inner cylindrical body portion 9.

The outer cylindrical body portion 3 and the inner cylindrical body portion 9 are integrally connected to the cap-shaped portion 13 at the connecting portion 7, and the cap-shaped portion 13 is the tip of the locking leg insertion hole 11. The side is closed like a bag and the locking leg insertion hole 11 is a bottomed hole.

The locking leg insertion hole 11 is open only at the inlet end on the left side in FIGS. 3 and 4, but has a tapered inner diameter Da that is slightly smaller than the inlet end inner diameter Db. In this case, the engagement leg portion f (see FIG. 5) formed on the back surface of the emblem E as a mounting component for fastening is received by interference fitting. Further, on the inner peripheral surface of the inner cylindrical portion 9 forming the locking leg insertion hole 11, a plurality of air vent grooves 15 are formed in the axial direction thereof.

An annular lip 17 is integrally formed on the outer periphery of the left end of the outer tubular body 3 in FIGS. 3 and 4, in other words, on the outer periphery of the engaging leg insertion hole 11 on the inlet end side. There is. Further, a check-shaped locking ridge 19 is provided on the outer peripheral portion on the right side in FIGS. 3 and 4. The outer diameter of the outer cylindrical body 3 between the annular lip 17 and the locking ridge 19 is determined by the component mounting member, that is, the clip mounting hole h formed in the outer panel P shown in FIG. The size is set so that it can be fitted externally.

FIG. 5 shows an example in which the emblem E is fixed to the outer panel P using the component fixing clip 1 described above. At the time of this fastening, an annular packing K made of sponge or the like is attached to the outer periphery of the outer tubular portion 3 on the side of the annular lip 17, and the component fastening clip 1 is attached from the cap-shaped portion 13 side to the clip mounting hole h of the outer panel P. Fit inside. As shown in the figure, when the component fixing clip 1 is fitted into the clip mounting hole h of the outer panel P up to the position where the locking ridge 19 gets over the outer panel P, the annular lip 17 sandwiches the packing K and the outer panel is sandwiched. The outer panel P comes into close contact with the outer surface of P in an elastically deformed state, and the outer panel P is fitted between the annular lip 17 of the outer cylindrical body portion 3 and the locking ridge 19. As a result, the state in which the component fixing clip 1 is mounted in the clip mounting hole h of the outer panel P is maintained by the non-returning action of the locking ridge 19. In this state, since the annular lip 17 is in close contact with the outer surface of the outer panel P with the packing K sandwiched therebetween in an elastically deformed state, the airtightness between the component fixing clip 1 and the clip mounting hole h of the outer panel P is maintained. Is secured.

Next, the locking leg f of the emblem E is inserted into the locking leg insertion hole 11. Locking leg part By inserting the locking leg part f into the insertion hole 11, they are coupled in an interference fit state, whereby the emblem E is fixed to the outer surface of the outer panel P.

When the locking leg portion f is inserted into the locking leg portion insertion hole 11, the air in the locking leg portion insertion hole 11 is discharged to the outside from the air vent groove 15. Therefore, the air in the locking leg insertion hole 11 is not trapped in the hole, and the locking leg f is inserted into the locking leg insertion hole 11 smoothly without requiring a large insertion force. Be seen.

When the air vent groove 15 is provided, rainwater or the like may enter the locking leg insertion hole 11 from the outside through the air vent groove 15. Since the portion insertion hole 11 is a bottomed hole whose tip side is closed like a bag by the cap-shaped portion 13, even if rainwater or the like enters the locking leg insertion hole 11, this will go inside the outer panel P 1. It will not be leaked.

In the above embodiment, the air vent groove 15 is formed on the inner peripheral surface of the inner cylindrical body portion 9, but it is formed on the outer peripheral surface of the locking leg portion f of the emblem E. Also, in this case, the same action and effect as those of the above embodiment can be obtained.

[0019]

[Effect of device]

 As can be understood from the above description, according to the component fixing clip of the present invention, the cap-shaped portion makes the locking leg insertion hole a bottomed hole, and water enters the locking leg insertion hole. However, since this does not flow out from the tip side of the locking leg insertion hole to the outside, there is a dimensional error in manufacturing between the locking leg insertion hole and the locking leg, or there is a problem due to long-term use. Even if a minute gap is created between the locking leg insertion hole and the locking leg due to deformation of the fitting part between the stop leg insertion hole and the locking leg or deterioration of the material, The waterproofness of the inside of the component fixing member such as the outer panel of the vehicle body is surely secured, and this is guaranteed for a long period of time.
