Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a holding clip that is effectively used when attaching a decorative plate, which is an interior component of an automobile, to a panel plate.

[Prior Art] Many techniques have already been disclosed for a clip for attaching a decorative plate, which is an interior component, to a panel plate through its own mounting hole.

For example, in U.S. Pat.No. 3,550,217, it is composed of a head and legs, and two flanges, one above and one below the other, extend parallel to the axis of the head, and a decorative plate is provided above and below the flange. , And the leg body is fixed by inserting a leg body having a W-shaped cross section that can elastically bend into the hole of the panel plate.

Further, in U.S. Pat.No. 3,745,612, it is composed of a head portion and leg portions, and the head portion has two upper and lower flanges extending in parallel with respect to an axis, and a decorative plate within the distance between the flanges. The holes are designed to lock.

Further, the leg body has an S-shape in cross section, is elastically expanded, and can be inserted and fixed by the elastic bending when being inserted into the panel hole.

However, when the mounting holes of the decorative plate are mounted and fixed between the upper and lower flanges, that is, at the height of the shaft center, the mounting holes have a shape of dharma K1. As shown in Fig. 9, the shaft center portion 1 disposed in the small hole portion of the dharma hole K1 is affected by the external pressure, and as shown in Fig. 9, passes through the joint passage K4 in the middle of the large and small holes. There was a problem that it was pushed back into the large hole and dropped off.

Therefore, as a countermeasure, strictly measure the size of the joint K4,
Moreover, even if the management is made such that the clip 1 does not go backward, the management has a large number of man-hours, which has been a problem.

[Problems to be Solved by the Invention] The present invention has been devised in view of the above-mentioned problems of the prior art. The purpose of the present invention is not only to prevent the dharma hole from falling due to backward movement, It is an object of the present invention to provide a retaining clip that can prevent the Dharma hole from falling off without strictly controlling the dimension of the Dharma hole.

[Means for Solving the Problems] The present invention has been devised to solve the above-mentioned problems, and includes a head for attaching a decorative plate to a dharma-shaped through hole. A holding clip formed continuously with the head portion and having a leg portion to be fixed to the panel hole by elastic expansion, the head portion having an axis at a central position, An upper flange and a lower flange extending parallel to each other with a gap from the axis are formed, and an elastic umbrella body is formed on the lower surface of the lower flange so as to contact the lower surface of the upper flange within the space between the upper and lower flanges. An elastic arm protruding only in one direction is extended, and the elastic arm has a shaft branch protruding from one direction of the shaft center, and the tip end of the shaft branch is bifurcated to extend in two directions and further inward. A dull that is bent to form a forked tip and to which a holding clip is attached It is formed in a shape corresponding to the shape of the hole, and is formed with a thickness that allows elastic deformation in the dharma hole. It is characterized in that it is configured to generate a tension resistance and prevent the holding clip from moving beyond a certain level.

[Operation] With this configuration, in the case of the holding clip, when the holding clip is attached to the dharma-shaped mounting hole of the decorative plate,
Even if the holding clip tries to move due to external pressure, it is possible to effectively prevent the holding clip from dropping due to the presence of the elastic arm of the self.

Therefore, even if an error occurs in the manufacturing size of the dharma hole which is the mounting hole, it is possible to effectively prevent the dharma hole from coming off from the dharma hole by the holding action of the elastic arm in the dharma hole. .

[Embodiment] An embodiment of the holding clip according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view of a holding clip 10 according to the present invention,
FIG. 2 shows a side sectional view.

Here, the structure of the holding clip 10 will be explained.
Head 11 for attaching to the through hole of the panel 11 to hold the decorative plate K, and legs for connecting to the head 11 and being fixed to the hole H of the panel P by elastic expansion. A holding clip consisting of a portion 12, wherein the head portion 11 has an axial center 13 at a central position, and an upper flange 14 and a lower flange 15 extending in parallel from the axial center 13 with a gap 17 and the lower flange. An elastic umbrella body 16 is formed on the lower surface of 15, and the upper and lower flanges 14, 15 are formed.
The elastic arm 18 which is in contact with the lower surface of the upper flange 14 and protrudes only in one direction is extended in the space 17.

That is, the main holding clip 10 is formed of a synthetic resin material, and as shown in the front view of FIG. 1, a head 11 and a leg portion 12 connected to the head 11. It consists of

The head 11 has a cylindrical shaft center 13 at the center position, and an upper flange extending from this shaft center 13 as a disk body.
14 and the lower flange 15 are formed with a predetermined gap 17.

Further, an elastic umbrella body 16 continuously provided on the bottom surface of the lower flange 15 is also formed in a disk shape as a flexible body which becomes thinner as it goes to the tip.

In addition, a leg portion 12 that is continuously provided on the head portion 11 is formed so as to hang down from a lower surface of the elastic umbrella body 16.

This leg portion 12 is inserted and fixed in the mounting hole H of the panel plate P, and the outer surface of the leg portion 12 is always elastically expanded and unfolded. It is formed in a W shape, and exerts an elastic force by receiving the force of external pressure from the outer wall surface.

Therefore, the shape of the leg portion 12 is sufficient as long as it has an ability as an elastic body, and can be appropriately formed other than this embodiment.

The most characteristic feature of the present invention is the presence of the elastic arm 18 shown in FIGS. 3 and 4.

That is, FIG. 3 is a view of the elastic arm 18 taken along the line AA of FIG. 2, and as described above, the shaft branch 18a projects from one direction of the shaft center 13, and the tip end of the shaft branch 18a has two ends. Further, it is branched into two, extends in two directions, and further bends inward to form a forked tip portion 18b.

The elastic arm 18 is formed in a shape corresponding to the shape of the dharma hole K into which the clip 10 is attached, and is formed in the dharma hole K with a thickness that allows elastic deformation freely.

FIG. 4 is an explanatory view taken along the line BB of FIG.

Such a retaining clip 10 is attached according to FIG.

That is, the panel plate P is provided with a circular hole H, and the decorative plate K is provided with a dharma hole K1. The dharma hole K1 has a large hole K2 and a small hole K3, and the joint passage K4 is formed by connecting the two holes, and the width dimension of the joint passage K4 is larger than the outer dimension of the shaft center 11. It has a slightly smaller size.

Then, if the upper flange 14 of the head 11 is inserted into the large hole K2, the elastic arm 18 hits the decorative plate K in the initial stage, but if it moves downward in the direction of the arrow, the axis of the joint path K4 becomes the axis 13. After passing, the shaft center 11 is completely moved to the hole of the small hole K3. At this time, the elastic arm 18 is completely stored in the large hole K2.

Since the elastic arm 18 extends from under the upper flange 14, it is held and fixed by the wall thickness of the dharma hole K1, that is, the wall thickness of the decorative plate K. The clip 10 is stably held on the decorative board K.

FIG. 6 is a view for explaining the stored state of the elastic arm 18 in relation to the dharma hole K1. As a result, the elastic arm 18 is attached to the large hole K2 while maintaining its natural shape.

When the holding clip 10 moves in the direction of the large hole K2 under the influence of the external pressure, the forked tip portion 18b of the elastic arm 18 elastically deforms in the large hole K2 according to FIG. Therefore, it is possible to effectively prevent the crib 10 from dropping from the dharma K1.

Thus, the holding clip 10 can be managed without requiring strict maintenance of the dimension of the Dharma hole K1, and at the same time, the holding clip 10 is guaranteed to be completely held even when the holding clip 10 is attached, and there is no worry about external pressure. It was

[Effects of the Invention] The present invention having the above-described configuration can achieve the following effects.

(1) When the holding clip moves in the direction of the large hole of the dharma hole due to the effect of external pressure, the bifurcated tip of the elastic arm causes a crushing resistance in the large hole, causing the clip to drop from the dharma hole. Can be effectively prevented.

(2) Due to the action of the elastic arm, the holding clip can be managed without requiring strict maintenance of the dimension of the dharma hole, and at the same time, a complete holding state is assured even during the attaching operation of the holding clip.
