[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a fixing structure for fixing a mounting clip for mounting various trims, kicking plates, etc. to an automobile body or the like to an object to be mounted such as the various trims described above. The present invention relates to a fixing structure of a mounting clip that can be securely fixed to an object and can be easily fixed and removed without damaging each member.

[0002]

[Prior Art]

 Conventionally, when various trims and kicking plates are mounted on the body of an automobile, as shown in FIG. 9, the brim-shaped locking plates b, b are formed on both ends of the shaft portion a having a short-axis columnar shape. A mounting clip in which a fitting protrusion c that fits into the mounting hole of the body is projected from one locking plate is used.

When various trims are attached to the body of an automobile by using such an attachment clip, a pocket-shaped fixing portion g having a keyhole-shaped fitting hole f is formed at a mounting portion of the trim e, and this fixing portion g The shaft portion a of the clip d is fitted and fixed in the fitting hole f to fix the clip d to the trim e, and the fitting protrusion c of the clip d is formed in a body (not shown) of an automobile. The trim e is attached to the body of the automobile by fitting and fixing the trim e.

In this case, the fitting hole f of the fixing part g is composed of a circular hole h and a cut-in fitting groove j extending from the circular hole h to the open end i, as is clear from the figure. The width of the fitting groove j is formed to be smaller than the diameter of the shaft a of the clip d, whereby the shaft a of the clip d fitted in the circular hole h is fixed without easily slipping out from the fitting hole f. It is supposed to be done. Further, the fixing portion g is made of a material having an appropriate flexibility, and when the shaft portion a of the clip d is inserted into the fitting hole f, the fitting groove portion j is bent by pressing the clip strongly, so that the shaft portion a. Can pass through the fitting groove portion j.

[0005]

[Problems to be solved by the device]

 However, the fixing structure of this mounting clip has the following problems. (1) Since the width of the fitting groove portion j is formed smaller than the diameter of the shaft portion a of the clip d and the clip d is attached to the fitting hole f of the fixing portion g by press fitting, the fitting groove portion j The dimensional relationship between the shaft part a and the shaft part a has a great influence on the workability at the time of mounting and the fixing force after mounting, and it is very difficult to fit the shaft part a into the fitting hole f due to a slight deviation in this dimensional relationship. On the contrary, the shaft part a may be easily removed from the fitting hole f.

(2) Absorption of the pitch deviation that occurs when various trims are attached using a plurality of clips is performed by forming the diameter of the circular hole h larger than the diameter of the shaft a. If a pitch shift that is difficult to absorb occurs when mounting the trim, it is difficult to adjust the pitch shift on the clip side. That is, in such a case, it is conceivable to reduce the diameter of the shaft portion a of the clip d. However, if the diameter of the shaft portion a is reduced, the clip d is inserted into the insertion hole in relation to the dimension of the nutrient device insertion groove portion j. It will be easier to get out of f.

(3) If the clip needs to be replaced for some reason, it is very difficult to remove the clip d from the fixing portion g, and the fixing portion g may be damaged.

The present invention has been made in view of the above circumstances, and it is possible to easily attach and detach a clip to and from a fixed portion without causing damage, etc. Even so, it is an object of the invention to provide a fixed structure of a mounting clip that can be easily dealt with on the clip side.

Various trims and the like can be attached to a body of an automobile by fitting and fixing the fitting protrusion of the above into an attachment hole formed in a base body to be attached such as an automobile body.

In this case, when the fitting flange portion of the mounting clip is fitted into the pocket-shaped fixing portion from the open end, the shaft portion of the mounting clip is inserted into the through groove of the fixing portion, and the fitting portions formed at both end portions of the shaft portion are inserted. The upper wall of the fixed part is sandwiched between the flange part and the locking flange part. At this time, for example, a locking small projection (locking portion) formed on the locking flange portion abuts against the upper surface of the fixed portion and is pressed, and the pressing flange bends due to this pressing force, and the locking small projection. Slides on the upper surface of the fixed part and reaches a small locking hole (locking part) formed in the fixed part, the locking flange elastically restores and the small projection for locking locks the fixed part. The mounting clip is fixed to the fixing portion by engaging with the small hole. Even if the engagement part of the locking flange part is a small hole and the locking engagement part of the fixed part is a small protrusion, the small protrusion slides on the lower surface of the locking flange part during the fixing operation. Is the same.

As described above, according to the fixing structure of the present invention, the upper wall of the fixing portion is sandwiched between the fitting flange portions and the engaging flange portions formed at both ends of the shaft portion of the mounting clip, and the engaging flange portion is secured. Since the locking portion provided and the locking engagement portion provided on the upper wall of the fixed portion are engaged with each other, the fitting flange portion is fixed so as not to come out of the fixed portion. By forming a locking part and a locking engaging part that can be fitted respectively on the locking flange part and the fixing part, good mounting workability and fixing force can be surely obtained and the conventional structure can be obtained. As described above, the dimensional accuracy does not significantly affect the mounting workability and the fixing force.

Further, since the pitch deviation can be absorbed by the dimensional relationship between the locking portion and the small projection of the locking engaging portion and the small hole, the mounting clip can be satisfactorily adjusted. Furthermore, during mounting, as described above, the small protrusion of the locking portion formed on the locking flange portion abuts on the upper surface of the fixed portion, or the small protrusion of the locking engagement portion formed on the fixed portion causes the locking flange. The contact flange is pressed against the bottom surface of the part, and this pressing force causes the locking flange part to bend and the small protrusion to slide on the upper surface of the fixed part or the lower surface of the flange part, making it extremely easy to perform the work. Moreover, after the work is completed, the locking portion of the mounting clip and the locking engagement portion of the fixed portion are securely engaged with each other, and the mounting clip is securely fixed to the fixed portion. Further, at the time of removal, by gripping the peripheral edge portion of the locking flange portion and bending the locking flange portion, the engagement state between the locking portion and the locking engaging portion can be easily released, It can be easily removed without damaging the fixing parts or clips.

Here, the mounting clip 1 has the configuration shown in FIGS. 3 to 6. That is, a flanged fitting flange portion 5 and a locking flange portion 6 are formed on both ends of the short shaft tubular shaft portion 4, respectively, and a substantially bud-shaped fitting projection 7 is formed on the outer surface side central portion of the locking flange portion 6. Along with the protrusions, small protrusions (locking portions) 8 for locking, which face each other with the shaft portion 4 sandwiched therebetween, are provided in the vicinity of the peripheral edge portion on the inner surface side of the locking flange portion 6. The mounting clip 1 is made of a plastic material having appropriate flexibility.

The fitting flange portion 5 is a plate-shaped member having one end formed in a semicircular shape, and is connected to the shaft portion 4 at the center of the one end semicircular portion, and formed in a linear shape. The end side projects more outward from the shaft portion 4 than the semicircular portion on the one end side. Further, the outer peripheral edge portion of the fitting flange portion 5 is a tapered portion which gradually becomes thinner toward the outer side.

As shown in FIG. 6, the locking flange portion 6 is a circular umbrella-shaped member which is gradually inclined outward (downward in the drawing) from the center portion toward the peripheral portion, and the center portion thereof is formed. And is connected to the shaft portion 4. Near the inner peripheral surface (upper surface in the figure) of the locking flange portion 6, small locking projections (locking portions) 8 are provided so as to project at positions facing each other with the shaft portion 4 interposed therebetween. (See Figures 3 and 4). The semicircular portion of the fitting flange portion 5 is located on one side of the line connecting the small projections 8 and the other end portion of the linear shape is located on the other side (see FIG. 3). ). The upper surfaces of the protrusions 8 and 8 on one end side are notched to form tapered portions 8a (see FIG. 6).

The fitting protrusion 7 is formed by forming three through holes 9, 9, 9 on the peripheral surface of the hollow bud-shaped base body at equal intervals from the axially intermediate portion to the base end. By the action of the through holes 9, 9, 9, the diameter is reduced when it is pressed inward from the outer peripheral surface, and when the pressed state is released, the diameter is restored elastically.

On the other hand, as shown in FIGS. 7 and 8, the fixed portion 3 has a linear open end 10 formed at a mounting portion of the mounted object 2 such as various trims and a semi-closed end 11 at the other end. It has a circular pocket shape and has a notch-shaped through groove 12 extending from the open end 10 to the center of the semi-circular closed end 11 and has a long shape sandwiching this through groove 12. Small-shaped locking small holes (locking engagement portions) 13, 13 are formed.

Here, the thickness of the hollow portion 14 of the fixing portion 3 is the same as or slightly thicker than the thickness of the fitting flange portion 5 of the mounting clip 1, and the fitting flange portion is inside the hollow portion 14. 5 can be inserted without rattling. The width of the through groove 12 is the same as or slightly larger than the diameter of the shaft portion 4 of the mounting clip 1, and the shaft portion 4 can be inserted into the through groove 12. Further, the locking small holes 13, 13 are formed to be larger than the locking small protrusions 8, 8 of the mounting clip 1.

As shown in FIGS. 1 and 2, the fixing structure of the present embodiment is one in which the mounting clip 1 is fixed to the fixing portion 3. However, when both are combined, the structure shown in FIG. Thus, the clip 1 fitting flange portion 5 is inserted into the hollow portion 14 of the fixing portion 3 from its circular end portion. As a result, the upper wall (lower wall in FIG. 8) of the fixed portion 3 is sandwiched between the fitting flange portion 5 and the locking flange portion 6, and the shaft portion 4 is inserted into the through groove 12 (see FIG. 2). .. At this time, when the fitting flange portion 5 of the mounting clip 1 is inserted into the hollow portion of the fixed portion 3, the small projections 8 and 8 projecting from the locking flange portion 6 come into contact with the upper wall of the fixed portion 3 and the small projection By the action of the taper portion 8a of 8,8, this is pressed and the peripheral edge portion of the locking flange portion 6 is bent outward, and the small projections 8,8 slide on the upper wall of the fixed portion 3. When the semi-circular end of the fitting flange 5 reaches the deepest part of the hollow portion of the fixed portion 3, the small protrusions 8 and 8 reach the small holes 13 and 13 of the fixed portion 3 and the pressed state is released. The locking flange portion 6 elastically restores, and the small projections 8 and 8 engage the small holes 13 and 13, respectively, as shown in FIG. As a result, the attachment clip 1 is fixed to the fixing portion 3.
