The mounting operability is excellent. In addition, since a metal clip is used, as an example of application, the cover 33 is the first on the clip side in that it is difficult to be destroyed even if it is subjected to an impact caused by an explosion of a vehicle airbag or a stepping stone from the road surface. There is also an advantage that the appearance can be maintained because the engaging portion 23 is covered.

  However, in this structure, first, the engagement fixing force with respect to the panel-side mounting hole is proportional to the inclination angle of the elastic piece, which is the second engagement portion 24 that cuts and raises a part of the first engagement portion 23. If the engagement fixing force is increased by changing the inclination angle, the insertion force into the mounting hole becomes excessive and the mounting operability is impaired. In addition, the hook 21 is inserted into the panel side mounting hole 61a with the clip 21 mounted on the base member 11, and the hook-like elastic piece 24 is inserted and engaged therewith. Hard to add.

  The object of the present invention is to solve the problems as described above, and is excellent in mounting operability as in Patent Document 1, and in addition to the advantage that the engagement portion with respect to the panel is difficult to be destroyed by the metal cover, the mounting operability is impaired. Therefore, it is possible to reliably maintain the engagement fixing force without any problems. Other purposes will be clarified in the description below.

  In order to achieve the above object, the present invention is specified by referring to the embodiment, and in the clip 4 mounted in the mounting hole 7a provided in the panel 7, the flange portion 10 disposed on the surface side of the panel, and A plurality of elastic legs 15 protruding from the lower surface of the flange portion and inserted into the mounting hole so as to be temporarily fixed, and through the flange portion 10 and communicated with a gap between the elastic legs 15.

In this state, the elastic legs 15 can be prevented from being deformed in the approaching direction. The cover 3 includes covering portions 30 to 32 and folded pieces 33 and 34 that extend from the covering portions 31 on both sides and abut on the flange portion 10 side. Hereinafter, details of each member will be clarified.

  Here, the female member 1 will be described with reference to FIGS. On the upper surface of the flange portion 10, there are a side wall 12 projecting inside the support wall portion 11 and a frame-shaped peripheral side surface 12 a that borders the outer side of the opening 14, and an opening 14 that is inside the peripheral side surface 12 a. Guide protrusions 13 are provided so as to protrude opposite to both sides of the guide protrusion 13. Each guide projection 13 has a substantially inverted L shape, and is inclined in a side view as shown in FIG. 6C with the upper side protruding above the opening 14.

  In addition, the support wall part 11 has the shaft hole 11a provided in the both sides of the side wall 12 on the coaxial line. In this example, the assist grip 5 is rotatable with respect to the two clips 4 engaged and fixed to the panel 7 via the pivots 6 inserted into the respective shaft holes 11a as schematically shown in FIG. (For this support structure, see Patent Document 1, Japanese Patent Application Laid-Open No. 2002-225613, etc.).

  On the lower surface of the flange portion 10, a pair of elastic legs 15 projecting on both sides of the opening 14 and facing each other, and elastic reinforcing legs 16 projecting on one side of each elastic leg 15. And abutting portions 17 and 18 projecting from the outside of the elastic reinforcing leg 16 and the other side of each elastic leg 15, respectively. Each elastic leg 15 is provided continuously with the guide protrusion 13 as shown in FIG. 6 (b), and is provided on the side surface on the abutting portion 17 side on the tip side as shown in FIG. 5 (a). 15a and an engaging portion 15b provided next to the location 15a. The engaging portion 15b is a portion that is elastically engaged with the hole edge of the mounting hole 7a. The concave portion 15 a is a portion that is fitted to the cover 3.

  The elastic reinforcing leg 16 is formed in a shallow hollow part at the middle part of the outer surface, and a pair of claw parts 16a provided on both upper sides of the hollow part and the left and right middle of the inner face (side facing the elastic leg 15). And a guide rib 19 extending to the opening side. Each claw portion 16 a is a place to be fitted to the cover 3. The guide rib 19 continues to the inclined invitation portion 19a. The invitation portion 19a has substantially the same inclination angle as the guide projection 13 as shown in FIG. The abutting portions 17 and 18 are arranged in parallel with the opening 14 in between. The abutting portion 17 is along the corresponding edge portion of the opening 14, and an intermediate portion excluding the left and right end sides is formed as a step 17a that is one step lower. The abutting portion 18 is parallel to the elastic reinforcing leg 16, and an intermediate portion is formed in a step 18 a that is one step lower, and the step 18 a is connected to the hollow portion of the elastic reinforcing leg 16 described above. In this example, the abutting portions 17 and 18 are brought into contact with the surface of the panel 7 in a state where the female member 1 is engaged with the mounting hole 7a of the panel as shown in FIGS.

  Then, the female member 1 described above is in a state in which each elastic leg 15 is reduced in diameter with respect to the mounting hole 7a of the panel in a state where the male member 2 is temporarily fixed and held as shown in FIGS. The engagement portion 15b is engaged with the hole edge by being inserted and restored to the original shape simultaneously with the insertion. When the female member 1 is further pushed from the temporarily fixed state as shown in FIGS. 2 and 3 (b) and the insertion portion 25 is press-fitted between the elastic legs 15, The respective elastic legs 15 are switched to the final stop state in which the elastic legs 15 cannot be deformed in the diameter reducing direction.

  Next, the male member 2 will be described with reference to FIGS. The operation part 20 corresponds to the head of the insertion part 25, and has a size that fits inside the frame-shaped peripheral side surface 12a. The insertion portion 25 has a generally tongue shape, and is provided on the outer surface and extends from slightly before the operation portion 20 to the vicinity of the tip, and a groove 27 extending substantially parallel to both sides of the groove 26, It has an intermediate rib 21 provided in the middle of the width of the inner side which is the opposite side and extending from the operation portion 20 to the tip, and a piece portion 22 integrated on both side surfaces of the intermediate rib 21.

  Among these, the groove 26 is fitted with the guide rib 19. The intermediate rib 21 is slidably disposed along the gap between the guide protrusions 13 with respect to the female member 1. At this time, each guide protrusion 13 is released in a space portion 23 formed between the insertion portion 25 and each piece portion 22. Further, on both side surfaces of the intermediate rib 21, there are provided a first engagement claw 28 that protrudes to a location closer to the front side and a second engagement claw 29 that protrudes to a location closer to the rear side. The first engaging claw 28 enables the male member 2 to be temporarily assembled to the female member 1 as shown in FIG. 3A, and the second engaging claw 29 connects the male member 2 to the female member 1 as shown in FIG. It can be stopped.

  Next, the cover 3 will be described with reference to FIGS. 2, 4 and 8. FIG. The cover 3 is a breath product, and includes a bottom surface side covering portion 30 that covers the front end surface side of each elastic leg 15 and the elastic reinforcing leg 16, and a front and back surface side covering that covers the front and rear surface sides of each elastic leg 15 and the elastic reinforcing leg 16. Part 31, both end side covering parts 32 covering both end surfaces of each elastic leg 15 and elastic reinforcing leg 16, and folded piece parts 33, 34 extending each covering part 31 upward.

  Of the covering portions 31 on both sides, one of the pair of fitting holes 38 to be fitted to each claw portion 16a of the elastic reinforcing leg is formed on one side, and the other is partitioned and bent through the slit 37a and each elastic leg of the elastic leg. A claw 37 that fits into the recess 15a is provided. The folded piece 33 is brought into contact with the tip 33 a in a state where the tip 33 a is positioned and engaged with the step 18 a of the abutting portion 18. The folded piece 34 is brought into contact with the tip 34 a being positioned and engaged with the step 17 a of the abutting portion 17.

(Assembly) Each member described above is assembled in the temporarily assembled state shown in each of FIGS. 1 to 3 according to the procedure illustrated below, and is handled as an integral clip 4. In this assembly, the cover 3 and the male member 2 are assembled together with the female member 1. Here, an example in which the male member 2 is assembled after the cover 3 is assembled to the female member 1 will be described. However, after the male member 2 is assembled to the female member 1, the cover 3 can be assembled later.

  In assembling the cover 3, the elastic legs 15 and the elastic reinforcing legs 16 are accommodated inside the covering portions 30 to 32, and the tips 33 a and 34 a of the folded piece portions are formed on the corresponding stepped portions 18 a and 17 a. Abut. Then, the covering portions 31 on both sides are fitted to the corresponding claw portions 16a of the elastic reinforcing legs with the respective fitting holes 38 on one side, and fitted to the corresponding recesses 15a of the corresponding elastic legs. To do. As a result, the cover 3 is positioned with respect to the female member 1 by the steps 17a and 18a, and is reliably integrated by fitting at a plurality of locations.

  In assembling the male member 2, the intermediate rib 21 is located in the opening 14 so as to enter the gap between the guide protrusions 13, and the groove 26 is fitted to the guide rib 29 from the invitation portion 29 a, so that the insertion portion 25 is pushed into the gap S from the opening 14. Then, as shown in FIG. 3A, the insertion portion 25 is inserted into the opening 14 of the female member 1 while the first engagement claw 28 of the intermediate rib is elastically displaced between the guide protrusions 13. It is pushed in and restored to its original shape at the same time as it passes, and is prevented from coming off, that is, temporarily assembled to the female member 1.

(Panel Mounting Operation) The clip 4 temporarily assembled as described above is temporarily fixed to the panel 7 by a one-touch operation as shown in FIGS. 2 and 3, and as shown in each (b). The temporary stop state can be switched to the final stop state by a one-touch operation. That is, the clip 4 temporarily assembled is restored when the elastic legs 15 of the female member 1 pass through the mounting hole 7a while being displaced in a direction approaching each other with respect to the panel 7. The joint portion 15b is temporarily fixed by engaging or locking with the hole edge of the mounting hole 7a. In this state, the panel 7 is sandwiched between the abutting portion 18 and the engaging portion 15b as shown in the enlarged view of FIG. As shown in the enlarged view of FIG. 2B, the metal cover 3 is not in contact with the panel 7 because the tips 33a and 34a of the folded piece portions are in the corresponding abutting portion side steps 18a and 17a. It has become. As a result, in this structure, since the metal panel 7 and the metal cover 3 are not in direct contact, that is, not in metal touch, there is no generation of scratches or abnormal noise caused by the metal coming into contact with each other.

  Further, when the operator pushes the operation unit 20 in the direction of the arrow in FIGS. 2 and 3A from the temporarily fixed state described above, the operation unit 20 opens the opening 14 as shown in FIG. It is moved in the same direction until the final closing stage and switched to the final stop state. In this process, the insertion portion 25 is smoothly moved along the inclination of the invitation portion 19 a and with the fitting of the groove 16 to the guide rib 19. In the final stop state, the tip of the insertion portion 25 is pushed into the gap S between the elastic legs 15. In this push-in, the second engaging claw 29 is pushed in while being elastically displaced between the guide protrusions 13, and is restored to its original shape at the same time as passing, and is prevented from coming off, that is, finally stopped. Therefore, in this structure, the elastic legs 15 are prevented from being displaced in the direction in which they approach each other, whereby the engagement of the engagement portion 15b with the attachment hole 7a is reliably maintained, and the engagement fixing force can be increased.

  Further, the metal cover 3 covers and protects at least the distal ends of both the elastic legs 15 and the elastic reinforcing legs 16, and the elastic legs 15 and the elastic reinforcing legs 16 as shown in FIG. 2 and FIG. A space 8 is maintained between the two. That is, in this structure, the cover 3 maintains the first space 8 a formed between the distal ends of the elastic legs 15 and the second space 8 b formed between the distal ends of the insertion portions 25. For example, when a stepping stone or the like hits the cover portions 30 to 32 of the cover and deforms, the shock is absorbed by the spaces 8a and 8b so that the respective portions are not easily destroyed. In this case, in this structure, since the second space 8b is larger than the first space 8a, the insertion portion 25 on the male member side is closer to the female member side as damage received from the cover 3 that is deformed by impact. It is less likely to be damaged than the elastic legs 15, thereby preventing the male member 2 from coming off or falling off due to an impact.

  In addition, the clip of this invention should just be equipped with the structure specified by a claim, and a detail can be changed with reference to the form example. For example, the support wall portion of the female member supports an article or member other than the assist grip or changes the shape of the cover portion of the cover.
