【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic partial perspective view showing an assembled state of a front bumper 1 of an automobile to which the present invention is applied. Both ends 1a and 1b of the bumper 1 are formed so as to surround the left and right side portions of the body 2 of the automobile, respectively, as shown in the figure. The male side clips 3, which are the first members of the clip according to the present invention, are attached to the proper positions of the bumper attaching portions on both sides of the body 2, respectively, and the male side clips 3 on the inside of the both ends 1a and 1b of the bumper 1 are attached. The female clips 4, which are the second members, are attached to the corresponding positions, respectively. Both clips 3 and 4 are molded of synthetic resin material.

In order to assemble the bumper 1 to the body 2, first, as shown by the arrow A in FIG. 1, the bumper 1 is fitted to the front portion of the body 2 and the clips 3 and 4 are substantially aligned with each other. Next, as shown by the arrow B, the respective end portions 1a and 1b are pushed into the side portion of the body 2 so that the clips 3 and 4 are engaged with each other, and the bumper 1 is temporarily fixed to the body 2. To be done. Then, the bumper 1 is completely fixed to the body 2 with a tapping screw or the like (not shown).

FIG. 2 is a plan view showing a state before the clips 3 and 4 at the one end 1a are engaged with each other, and FIG. 3 is a perspective view thereof. Since the same applies to the other end 1b, its illustration and description are omitted.

As shown in FIGS. 2 and 3, the male clip 3 includes a leg portion 5 that is inserted into an attachment hole 2 a provided in the body 2, and a neck portion 6 that projects from the leg portion 5. It comprises a flared portion 7 formed at the protruding end of the neck portion 6, and a flange portion 8 provided between the leg portion 5 and the neck portion 6 and radially outward with respect to the axis of the leg portion 5. Also, the female clip 4 extends in a bilaterally symmetrical manner from the leg 9 inserted into a mounting hole 1c provided in, for example, an integrally formed anchor portion of the end 1a of the bumper 1, and from the leg 9. Is formed between the pair of elastic clamp pieces 10 having a C-shaped cross section, the leg 9 and the base of the elastic clamp piece 10, and is formed radially outward with respect to the axis of the leg 5. And a flange portion 11.

The expanding portion 7 of the male clip 3 has a spindle shape as well shown in FIG. 3, and its major axis extends through the leg 5 and the neck 6 in the front-back direction of the paper surface of FIG. It is formed so as to be orthogonal to the axis. The male clip 3 is also coaxially formed with a bottomed axial hole 3a that opens to the outer peripheral surface of the central portion of the expanding portion 7 and reaches the middle portion of the leg portion 5. A pair of blade-shaped elastic engaging pieces 5a extending from the tip to the vicinity of the flange 8 are symmetrically formed. After inserting the leg portion 5 into the mounting hole 2a of the male clip 3, the leg portion 5 swells by screwing a screw (not shown) into the axial hole 3a, and the pair of elastic engagement pieces 5a also expands. Therefore, it is preferably locked and fixed.

Further, the extending ends of the elastic clamp pieces 10 of the female clip 4 are curved so that the opening 12a of the recess 12 defined by the elastic clamp pieces 10 is slightly narrowed toward the inside. After that, it is bent so that it spreads out in a V shape so as to move away from each other. A pair of inward projections 13 projecting from each other are provided at the portions of the elastic clamp pieces 10 that define the openings 12a. The two inward projections 13 are elastically deformed by the flexibility of the two elastic clamp pieces 10 so as to widen the width of the opening 12a.

The portions of the elastic clamp pieces 10 that define the recessed portion 12 are formed so as to form a part of a cylindrical shape having an axis that is orthogonal to the axis of the leg 9. The inner diameter of the cylindrical portion is the same as or slightly smaller than the maximum outer diameter of the expanding portion 7 in the direction orthogonal to the long axis, so that the expanding portion 7 can be received in the recess 12. There is. The leg portion 9 of the female clip 4 is also provided with a pair of elastic engagement pieces 9a having an outwardly protruding engagement protrusion in the radial direction so as to be openable and closable in the radial direction, and the anchor of the bumper end 1a is provided. When the leg part 9 is inserted into the mounting hole 1c until the flange part 11 hits the part, the protrusion of the elastically engaging piece 9a which is elastically restored engages with the back surface of the anchor part and the female side clip 4 comes off. Will be stopped.

An engaging surface 7 a, which is a flat surface parallel to the long axis of the expanding head 7, is provided on the neck 6 side of the expanding head 7 so as to surround the neck 6. Further, in order to prevent the expansion heads 7 from coming off, the sides of the both inward projections 13 of both elastic clamp pieces 10 facing the recessed portion 12 side are in a state where the expansion heads 7 are received in the recessed portions 12. It is formed in a flat surface shape so as to surely engage with the engagement surface 7a.

In order to engage both the clips 3 and 4 thus configured, the expanding head 7 of the male clip 3 is inserted into the recess 12 of the female clip 4, As shown by the arrow C 2 in FIG. 2, the opening 12a of the female clip 4 and the expanding portion 7 are aligned, and the female clip 4 is pushed into the male clip 3. At this time, since the expanding head 7 is guided by the C-shaped free ends of both elastic clamp pieces 10, the expanding head 7 can be easily inserted into the recessed portion 12. In this way, the expanded head 7 is received in the recessed portion 12, the bumper 1 is temporarily fixed, and a tapping screw or the like is screwed into another position to completely fix the bumper 1 to the body 2.

In the temporarily fixed state, the engagement surface 7a of the expansion head 7 and the inward projection 13 are engaged to firmly prevent the expansion head 7 from coming off, so that the opening of the U-shaped bumper 1 is opened. Can be prevented. Further, since the long axis of the spindle-shaped expanding portion 7 and the axial direction of the recessed portion 12 coincide with each other and can be relatively displaced in that direction, when the clips 3 and 4 are engaged with each other, It is possible to adjust the position to some extent with respect to the vertical direction of the automobile, which is the longitudinal direction of the expansion head 7. Therefore, the vertical pitch shift due to the mounting error of both clips 3 and 4 can be allowed to some extent.

[0018]

[Effect of device]

 Thus, according to the present invention, the position of the spindle-shaped expanding head can be adjusted in the long axis direction, and the inward projection and the expanding head provided at the opening of the recess are engaged with each other. Since it can be temporarily fixed by being prevented from coming off, it can be temporarily fixed and the position can be adjusted when the two members are assembled, and the assembly workability can be improved by completely fixing the two members after the position adjustment.
