DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable clip for attaching, for example, a resin part to a steel plate body of a vehicle.

[0002]

2. Description of the Related Art FIGS. 10 and 11 are external views showing a conventional clip. After the clip shown in these drawings has attached its attachment portion 40 to a predetermined resin product,
Locking leg 42 integrally formed from substrate 41 of mounting portion 40
Into a mounting hole of a vehicle body which is a member on the other side.
Thus, the resin component is attached to the body via the clip. The clip shown in FIG.
2 and the substrate 41 is supported by the support 4
6 are connected. On the other hand, the clip shown in FIG.

When the locking leg 42 is inserted into the mounting hole of the body, the locking leg 42 enters the mounting hole while being compressed in the width direction by the edge of the mounting hole.
Pass through the mounting hole. When the locking leg 42 is removed, the locking leg 42 is stretched by being pulled in the length direction with the shoulders 44 on both sides hooked on the mounting hole, and comes out of the mounting hole.

[0004]

In the clip shown in FIG. 10, even if an excessive resistance is received when the locking leg 42 is inserted into the mounting hole of the body, the locking leg 42 is rigidly supported by the support column 46. It can be inserted lightly. However, on the other hand, when pulling out the locking leg 42 from the mounting hole of the body, the locking leg 42 does not extend well in the length direction due to the support column 46, and it becomes difficult to remove the clip. on the other hand,
In the clip shown in FIG. 11, the locking leg 42 can be easily pulled out from the mounting hole of the body.
Is only deformed, and it is difficult to overcome this resistance.

[0005] An object of the present invention is to make it possible to cope with an excessive resistance force when inserting a locking leg of a clip despite easy attachment and detachment of the clip to and from a mounting hole. An object of the present invention is to make it possible to arbitrarily set the pulling load of the locking leg.

It is an object of the present invention to make it possible to provide a sufficient strength against a force applied when the locking leg is removed from the mounting hole.

[0007]

According to the first aspect of the present invention,
A clip provided with a locking leg detachable from a mounting hole of a mating member for mounting a component, wherein the locking leg is formed integrally with a substrate and formed in a loop shape having a tip portion as a turning point. At the same time, this locking leg is capable of elastic deformation such as a change in the dimension between the tip and the substrate and the dimension in the width direction. Are separated on the way, and the separated portion is connected via an elastic body.

Accordingly, when the locking leg is inserted into the mounting hole of the mating member, the locking leg is compressed in the width direction and enters the mounting hole. When the body is deformed, a pulling force acts on the locking leg, and the dimension in the width direction is reduced, so that the locking leg comes off the mounting hole. Therefore, the clip can be easily attached to and detached from the mounting hole. Also, if an excessive resistance is received when the locking leg is inserted into the mounting hole, the separated portion of the column flexes and joins the elastic body, and thereafter the locking leg is lightly inserted using the rigidity of the column. it can. Moreover, by adjusting the elasticity of the elastic body, it is possible to arbitrarily set the load for extracting the locking leg.

According to a second aspect of the present invention, there is provided the clip according to the first aspect, wherein the elastic body has a ring shape.
Due to the shape of the elastic body, sufficient strength can be given to the force applied to the clip when the locking leg is pulled out from the mounting hole.

[0010]

Embodiments of the present invention will be described below. FIG. 1 is an external view showing a clip.
1A is a front view, FIG. 1B is a right side view, and FIG. 1C is a bottom view. FIG. 2 is an external perspective view of the clip. As shown in these drawings, the clip is roughly composed of a mounting portion 10 and a locking leg 12, and the whole is an integrally molded product formed by resin molding. And the mounting part 10
Are a disk-shaped substrate 11 and its auxiliary plate 11
a are arranged in parallel at a predetermined interval.

The locking leg 12 is formed integrally from the lower surface of the substrate 11 and has a loop shape with its tip 14 as a turning point. This locking leg 12
Is elastically deformable with respect to the substrate 11, and its length dimension, that is, the dimension between the tip 14 and the substrate 11 and the width dimension can be changed. Locking leg 1
In FIG. 2, both sides close to the substrate 11 are shoulders 16 that protrude most outward in the left and right directions.

A column 20 is formed inside the locking leg 12 and is separated from the base plate 11 and the tip 14 of the locking leg 12. That is, the strut 20 is separated into an upper strut 22 on the side of the substrate 11 and a lower strut 23 on the side of the locking leg 12, and a gap of a predetermined size is provided at a mutual tip. The upper support 22 and the lower support 23 are connected to each other by an elastic body 26.

FIG. 3 is a sectional view taken along line DD of FIG.
FIG. 2 is an external perspective view of a clip in which a part of a locking leg 12 is broken. As is clear from these drawings, the elastic body 2
Numerals 6 each have a semi-circular shape on both sides of the support column 20, and are set as a substantially circular ring shape as a whole. Due to the elastic deformation of the elastic body 26 and the elastic deformation of the locking leg 12, the upper support 22 and the lower support 23 can approach and separate from each other.

Next, the procedure for using the clip configured as described above will be described. First, the clip attaching portion 10 is attached to the resin component 30 shown in FIG. A part of the outer periphery of the mounting hole 31 of the resin component 30 is opened, and the substrate 11 and the auxiliary plate 11a are assembled using the mounting hole 31 so as to be located on both side surfaces of the resin component 30. In this state, the locking leg 12 is inserted into the mounting hole 34 of the body 32 which is a mating member of the resin component 30. FIG.
The locking leg 12 is in contact with the inner periphery of the mounting hole 34 and is compressed in the width direction as shown in the drawing, and the shoulders 16 pass through the mounting hole 34 and are Get into it.

As a result, as shown in FIG. 6, the locking leg 12 is locked in the mounting hole 34 of the body 32, and the resin component 30 is mounted on the body 32 through the clip. In this state, if an external force in the direction of removing the resin component 30 from the body 32 acts on the clip,
As long as the shoulders 16 are engaged with the edges of the mounting holes 34 of the body 32, and the external force exceeding this engaging force does not act on the clip, the resin component 30 is kept attached to the body 32.

When the resin part 30 is to be positively removed from the body 32, the resin part 30 is pulled in a direction in which the locking leg 12 is removed from the mounting hole 34 of the body 32.
As shown in FIG. 7, even after both shoulders 16 of the locking leg 12 engage with the edge of the mounting hole 34 of the body 32, the mounting portion 10
Is further pulled, the elastic body 26 is deformed into a vertically long ring shape, and a pulling force acts on the locking leg 12. As a result, the dimension of the locking leg 12 in the width direction is reduced, and the locking leg 12 comes out of the mounting hole 34 of the body 32.

Since the elastic body 26 has a ring shape, it exerts sufficient strength against the force applied to the clip when the locking leg 12 is pulled out. Moreover, since the elasticity of the elastic body 26 is a major factor in determining the load for removing the locking leg 12, the removal load of the locking leg 12 can be reduced only by adjusting the elastic force (for example, the wall thickness). It can be set arbitrarily.

Further, for example, when the diameter of the mounting hole 34 is too small, or when there are a plurality of mounting holes 34 of the clip and the body 32 mounted on the resin part 30 and the pitch between the clip and the mounting hole 34 is shifted. In some cases, excessive resistance may be applied when the locking leg 12 is inserted into the mounting hole 34. However, in such a case, as shown in FIG. 8, the column 20 bends the elastic body 26 to fill the gap between the upper column 22 and the lower column 23 and join them. Therefore, after this, the locking legs 12
Is easily inserted into the mounting hole 34 of the body 32.

The upper strut 22 constituting the strut 20
The gap between the lower support 23 and the lower support 23 may be freely set in relation to the elastic force of the elastic body 26 and the like. For example, as shown in FIG. Can be set large.
