  In Patent Document 1, the two engaging claws protruding from the rear surface of the flange portion of the female member are bent and pushed into the insertion hole of the mounting member, thereby engaging the engaging claw portion with the insertion hole. The clip is temporarily held on the mounting member. In this case, when the plate thickness of the mounting member is thick, there is no particular problem, but when the plate thickness is thin, the length of the engaging claw portion must be set short, and the engaging claw portion is difficult to bend. There is a problem in workability when the clip is assembled to the mounting member.

  The above Patent Document 2 has the same problem as the above Patent Document 1. That is, when the plate thickness of the mounting member is thin, the distance from the flange to the latching portion in the bush shaft portion must be shortened, and when the latching portion is engaged with the rear edge of the insertion hole, the bush shaft portion Becomes difficult to bend, and there is a problem in workability when the clip is assembled to the mounting member.

  Moreover, in the said patent document 2, the axial part of the bush which provided the two latching | locking parts which contribute to temporary holding | maintenance of a clip protrudes from the back side of the insertion hole of an attachment member in the state where the clip was temporarily hold | maintained at the attachment member. Yes. For this reason, when an unexpected external force acts on the shaft portion of the bush, the two locking portions may come off from the insertion hole, and the temporary holding state may be released.

  Therefore, the object of the present invention is to ensure that the clip can be easily assembled to the attachment member even when the plate thickness of the attachment member is thin, and that the clip can be detached from the attachment member in the assembled state. An object of the present invention is to provide an assembly structure of a clip and an attachment member that can be prevented.

In order to achieve the above object, a first aspect of the present invention includes a flange portion and a locking leg extending on the back surface thereof, and is held by a mounting member, and the locking leg is inserted into a mounting hole of a mounted member.

  Hereinafter, with reference to FIGS. 1-6, 1st Embodiment of the assembly | attachment structure of the clip concerning this invention and an attachment member is described.

  As shown in FIG. 6, a structure is known in which a mounting member 30 is fixed to a mounted member 1 via a clip 10. The clip and attachment member assembly structure (hereinafter referred to as “assembly structure”) according to the present invention is temporarily held by the attachment member 30 prior to the fixing operation of the attached member 1 and the attachment member 30. This relates to the assembly structure of the clip 10 and the mounting member 30. Examples of the mounted member 1 include a body panel of an automobile, and examples of the mounting member 30 include a panel member, a garnish, a trim board, a cover, an assist grip, and the like, but these are not particularly limited.

  As shown in FIG. 1, the clip 10 used in the assembly structure of this embodiment is a so-called two-piece clip including a grommet 11 and a pin 15 inserted into the grommet 11. The grommet 11 includes an annular flange portion 12 having an insertion hole 12a at the center, and a plurality of locking legs 13 extending from the periphery of the insertion hole 12a on the back surface of the flange portion 12. The plurality of locking legs 13 are formed by dividing the cylindrical portion on the back surface side of the flange portion 12 into a plurality of portions via the dividing groove 13a, and can be bent. A pressing projection (not shown) projects from the inside of each locking leg 13.

  In addition, a plurality of convex portions 12 b are projected from the surface of the flange portion 12 with an equal interval in the circumferential direction. A tool such as a flat-blade screwdriver is inserted between the adjacent convex portions 12b and 12b so that the pin 15 inserted into the grommet 11 can be removed.

  On the other hand, the pin 15 includes a disk-shaped head portion 16 and a shaft portion 17 that is suspended from the center of the back surface of the head portion 16. A rib 18 is formed on the outer periphery of the shaft portion 17 so as to enter the dividing groove 13 a of the grommet 11. A temporary fixing claw 18 a is formed in the middle of the rib 18. Further, an annular protrusion 17 a is provided at the tip of the shaft part 17.

  Then, the shaft portion 17 of the pin 15 is inserted partway through the grommet 11. That is, when the annular protrusion 17a of the shaft portion 17 is inserted to the front of the pressing protrusion on the inner side of the locking leg 13, the temporary fixing claw 18a engages with the rear peripheral edge of the insertion hole 12a, and the locking leg 13 does not expand in diameter. In this state, the pin 15 is temporarily fixed to the grommet 11 (see FIG. 5). In this state, the locking leg 13 can be inserted into the insertion hole 32 (described later) of the mounting member 30 and the mounting hole 3 of the mounted member 1.

  Further, when the pin 15 is further pushed in from the above state, the pressing projection inside the locking leg 13 is pressed by the shaft portion 17 so that the locking leg 13 expands in diameter, and when the pressing projection gets over the annular projection 17a, The pressing protrusion is engaged with the base end side of the protrusion 17a, and the locking leg 13 is maintained in an expanded state so as to engage with the mounting hole 3 (see FIG. 6).

  As described above, the two-piece clip used in this embodiment can be inserted into the insertion hole 32 of the mounting member 30 and the mounting hole 3 of the mounted member 1 with the pin 15 inserted halfway into the grommet 11. By inserting the pin 15 further deeper, the diameter of the locking leg 13 of the grommet 11 is increased and fixed to the mounting hole 3.

  Next, the structure of the attachment member 30 will be described. The mounting member 30 of this embodiment is formed from a thin plate member. For example, a metal plate member such as SPCC (cold rolled steel plate) or SPFC (hot rolled steel plate) or a synthetic resin plate member such as PP (polypropylene) or PE (polyethylene) may be employed. Can do.

  A circular insertion hole 32 into which the locking leg 13 of the clip 10 is inserted is formed at a predetermined location of the mounting member 30. A pair of slits 34 and 34 are formed with a predetermined length from the position facing the circumferential direction of the insertion hole 32, and one end of each slit 34 communicates with the insertion hole 32. . The pair of slits 34, 34 form an elastic piece 36 that can be bent on the mounting member 30. Further, the tip 36a of the elastic piece 36 forms a part of the inner periphery of the insertion hole 32 and has a shape recessed in an arc shape.

  The elastic piece 36 of this embodiment is formed in a belt shape extending at a constant width. And this elastic piece 36 is comprised so that it can bend and deform | transform until the flange part 12 contact | abuts the surface of the attachment member 3 when the latching leg 13 is pressed. That is, as shown in FIG. 2A, when the locking leg 13 of the clip 10 is pressed against the elastic piece 36, the elastic piece 36 begins to bend, and when the clip 10 is further pressed, the clip 10 is shown in FIG. As described above, the elastic piece 36 can be bent and deformed until the elastic piece 36 is largely bent and the flange portion 12 of the clip 10 contacts the surface of the mounting member 30.

  In the above state, the pressing piece 40 described later is positioned above the surface of the flange portion 12 and the guide groove G communicating with the insertion hole 32 is formed by the bending deformation of the elastic piece 36. (See FIGS. 2B and 2C). Then, when the locking leg 13 is inserted into the insertion hole 32 and moves until it comes into contact with the inner periphery thereof, the elastic piece 36 is elastically restored to its original shape, and its tip 36 a is positioned at the peripheral edge of the locking leg 13. The return of the locking leg 13 is prevented (see FIG. 2 (d) and FIG. 4).

  Further, when the locking leg 13 moves until it hits the inner periphery of the insertion hole 32, the distal end 36 a of the elastic piece 36 (part of the inner periphery of the insertion hole 32 is formed so that the locking leg 13 is separated from the elastic piece 36. Part) is set. That is, the inner diameter D of the insertion hole 32 is formed to match the outer diameter of the locking leg 13 or larger than the outer diameter of the locking leg 13 (see FIG. 4). As a result, when the locking leg 13 is completely inserted into the insertion hole 32, the elastic piece 36 is elastically restored.

  In addition, although a pair of slits 34 and 34 in this embodiment are mutually formed in parallel, it is not limited to this. For example, the distance between the pair of slits 34, 34 may be narrowed toward the insertion hole 32, and the slits 34, 34 may be formed so as to form a substantially C shape. In this case, since the base end side of the elastic piece 36 is wide, it is easy to press the locking leg 13 of the clip 10 against the elastic piece 36, and the elastic restoring force of the elastic piece 36 can be improved.

  The attachment member 30 is further formed with a presser piece 40 that cuts and raises the clip 10 so as to restrict the movement of the locking leg 13 in the pulling direction. In this embodiment, a pair of presser pieces 40 are arranged at the periphery of the insertion hole 32 and on both sides of the elastic piece 36 in the extending direction.

  That is, the notches 38 are formed on the peripheral edges on both sides of the insertion hole 32 along the extending direction of the elastic piece 36. As shown in FIG. 4, each notch 38 has a pair of short grooves 38a, 38a orthogonal to the extending direction of the elastic piece 36, and extends in parallel to the extending direction of the elastic piece 36, and a pair of short grooves 38a. , 38a, and a long groove 38b connected to the tip of 38a. One of the pair of short grooves 38 a and 38 a is disposed on the proximal end side with respect to the distal end 36 a of the elastic piece 36, and the other is disposed at a position beyond the insertion hole 32. Further, a guide forming groove 38c extending in parallel with the long groove 38b is formed in the notch 38 from the proximal end of the short groove 38a on the elastic piece 36 side toward the insertion hole 32 side.

  A pair of presser pieces 40, 40 are formed by cutting and raising from the back surface to the front surface of the mounting member 30 through the notch 38 having the above shape. As shown in FIG. 5, the pair of presser pieces 40, 40 are inclined at a predetermined angle with respect to the surface of the mounting member 30 so that their upper ends (side edges opposite to the bent portions) are close to each other. It is bent. Thus, the pair of presser pieces 40, 40 formed by cutting and raising are arranged in parallel to the extending direction of the elastic piece 36 (see FIG. 1).

  Each presser piece 40 is cut and raised so that the height H (see FIG. 5) from the surface of the mounting member 30 to the upper end of the presser piece 40 is larger than the thickness of the flange portion 12 of the clip 10. . As a result, when the locking leg 13 of the clip 10 is inserted into the insertion hole 32, the pair of presser pieces 40, 40 are arranged above the surface of the flange portion 12, and the locking leg 13 moves in the removal direction. Are now regulated.

  Each presser piece 40 cut and raised as described above is further bent so that the end on the elastic piece 36 side is separated from the surface of the mounting member 30 via the guide forming groove 38c. There is no.

  As described above, since the attachment member 30 in this embodiment is formed of a plate-like member, each part of the insertion hole 32, the elastic piece 36, and the presser piece 40 is punched and bent by, for example, pressing. The mounting member 30 can be easily manufactured.

  Next, the usage method of the assembly structure which consists of the said structure is demonstrated.

  First, the pin 15 is inserted into the grommet 11 halfway, and the temporary fixing claw 18a is engaged with the rear side periphery of the insertion hole 12a, and the pin 15 is temporarily fixed to the grommet 11 without expanding the locking leg 13 in diameter. .

  Then, the head 16 of the pin 15 is gripped and the locking leg 13 is pressed against the proximal end side of the elastic piece 36. Then, as shown in FIG. 2A, since the elastic piece 36 is pressed by the locking leg 13, the elastic piece 36 bends to the back side of the mounting member 30. At this time, since the elastic piece 36 is separated from the attachment member 30, a guide groove G communicating with the insertion hole 32 is formed.

  While the locking leg 13 is guided toward the insertion hole by the guide groove G, the locking leg 13 is further pressed against the elastic piece 36. Then, the flange portion 12 passes through the guide portion 41 and enters the back surface side of the presser piece 40, and the elastic piece 36 is greatly bent so that the flange portion 12 can be brought into contact with the surface of the mounting member 30 (FIG. 2). (See (b)).

  At this time, since the flange portion 12 is suppressed from being caught by the end portion of the presser piece 40 by the guide portion 41 of the presser piece 40, the flange portion 12 can be smoothly inserted into the back surface side of the presser piece 40.

  After that, as shown in FIG. 2C, the clip 10 is moved in the insertion hole direction while the elastic piece 36 is bent against the elastic restoring force and the locking leg 13 is guided through the guide groove G. Let When the locking leg 13 is inserted until it hits the inner periphery of the insertion hole 32, the locking leg 13 is separated from the elastic piece 36, and the elastic piece 36 is elastically restored, as shown in FIG. The distal end 36a is positioned on the periphery of the locking leg 13 (in this embodiment, the distal end 36a abuts on the periphery of the locking leg 13). As a result, the locking leg 13 is prevented from returning to the base end side of the elastic piece 36, and the clip 10 can be held in the insertion hole 32.

  As shown in FIG. 2B, when the elastic piece 36 is elastically restored in a state where the flange portion 12 is inserted on the back surface side of the holding piece 40 and is not separated from the surface of the mounting member 30, The tip is pressed, and an urging force that moves the clip 10 toward the insertion hole acts. Therefore, it becomes easy to move the clip 10 to the insertion hole 32.

  Further, in this state, as shown in FIGS. 3 and 5, the flange portion 12 of the clip 10 is inserted on the back side of each presser piece 40, and each presser piece 40 is disposed above the surface of the flange portion 12. The movement of the locking leg 13 in the pulling direction is restricted. As a result, the clip 10 can be reliably prevented from coming off from the insertion hole 32.

  In this embodiment, the pair of presser pieces 40, 40 are arranged at the periphery of the insertion hole 32 and on both sides in the extending direction of the elastic piece 36, so that the opposing positions of the flange portion 12 are balanced over a wide range. The clip 10 can be held firmly and firmly held at the position of the insertion hole 32.

  As described above, in this assembly structure, the assembly operation shown in FIGS. 2A to 2D, that is, the guide groove G while the elastic piece 36 is bent while pressing the locking leg 13 against the elastic piece 36. The clip 10 can be assembled to the mounting member 30 with a simple operation by simply moving the locking leg 13 to the insertion hole 32 via the, thereby improving the workability of assembling the clip 10 and the mounting member 30. Can do. Further, even if the plate thickness of the mounting member 30 is thin, in this assembled structure, the elastic piece 36 itself is configured to bend by pressing the clip 10, so that the above-mentioned cited documents 1 and 2 are used. In addition, the ease of bending of the leg portions of the clip does not become a problem, and the clip 10 and the attachment member 30 can be assembled smoothly.

  Further, the clip 10 is held by the pair of presser pieces 40 and 40 and is prevented from returning by the tip 36 a of the elastic piece 36, so that the clip 10 can be firmly held in the insertion hole 32. . For example, even if a pulling force or impact force is applied to the clip 10 or vibration is transmitted to the clip 10 while the mounting member 30 is being conveyed, the clip 10 is prevented from falling off the mounting member 30, The clip 10 can be reliably assembled to 30.

  Furthermore, the elastic leg 36 is bent by pressing the locking leg 13 of the clip 10 against the elastic piece 36 of the mounting member 30, and the flange portion 12 is brought into contact with the surface of the mounting member 30. Since it is possible to make the moving path of the clip 10 long without making the hole for inserting the clip 10 a long hole, the presser piece 40 can be provided long along the moving direction of the locking leg 13. The clip 10 can be firmly assembled to the mounting member 30.

  Furthermore, since the elastic piece 36 is bent to move the locking leg 13 to the insertion hole 32, it is not necessary to form the insertion hole 32 as a long hole, and when the locking leg 13 moves to the insertion hole 32. Since the tip 36a of the elastic piece 36 is positioned at the periphery of the insertion hole 32, a large gap is not formed at the periphery of the insertion hole 32, and the appearance can be improved.

  As described above, after the clip 10 is assembled to the mounting member 30, the locking leg 13 (see FIG. 5) protruding from the back side of the insertion hole 32 is inserted in alignment with the mounting hole 3 of the mounted member 1. The mounting member 30 is brought into contact with the surface of the mounted member 1. Thereafter, the pin 15 is pushed deeply into the grommet 11 to increase the diameter of the plurality of locking legs 13 and engage with the rear peripheral edge of the mounting hole 3. As shown in FIG. The attachment member 30 can be fixed to the attachment member 1.

  In this embodiment, a two-piece clip including a grommet 11 and a pin 15 is employed as the clip 10 to be assembled to the attachment member 30. Therefore, as described above, after attaching the clip 10 to the attachment member 30, the attachment member 30 is attached to the attachment member 1 by a simple operation of inserting the locking leg 13 into the attachment hole 3 and pushing the pin 15 deeply. The workability can be improved. In addition, since the locking leg 13 of the grommet 11 constituting the two-piece clip is not expanded in diameter before the pin 15 is pushed deeply, the locking leg whose diameter has been expanded is inserted into the mounting hole 3 in advance. The insertion resistance can be made smaller than the case where the locking leg 13 can be smoothly inserted into the mounting hole 3.
