  Hereinafter, a typical embodiment of the present invention will be described with reference to FIGS. The clip C according to this embodiment includes the elastic engagement piece 3 and the head 1 provided in the clip C by inserting the leg portion 2 constituting the through hole Pa formed in the fastening object P. The fastening object P is sandwiched between them and fastened to the fastening object P.

  The clip C is typically used for fastening two panels P ′ and P ′ as the fastening objects P each having the through hole Pa through the clip C. (FIG. 4) In such a case, the leg portion 2 is inserted into the through hole Pa communicated from the state in which the two panels P ′ and P ′ are overlapped so that the respective through holes Pa communicate with each other. Thus, the two panels P ′ and P ′ are sandwiched between the elastic engagement piece 3 and the head 1, and the two panels P ′ and P ′ are fastened by the clip C.

  The clip C includes a head 1 having a size that does not enter the through hole Pa formed in the fastening object P, and a leg 2 that can be inserted into the through hole Pa. The leg portion 2 has an elastic engagement piece 3 that allows the insertion by elastic deformation and elastically recovers when it is pulled out from the through hole Pa and clamps the object P to be clamped with the head 1. It is provided in multiple stages in the insertion direction. Further, the leg 2 has a position different from the position where the elastic engagement piece 3 is formed in a direction around the leg axis of the leg 2 at a position where the leg 2 is completely inserted into the through hole Pa. A moderation feeling creation engaging portion 4 that is engaged with the fastening object P is provided.

  In the illustrated example, the head 1 has a circular umbrella shape. One end of the leg 2 is integrally connected to the curved inner side of the head 1. The leg portion 2 has a substantially rectangular cross-sectional shape in a direction perpendicular to the leg axis. Therefore, the leg part 2 has two narrow side surfaces 2a and 2a and two wide side surfaces 2b and 2b. Further, an interval is formed between the outer edge of the head 1 and the outer surface of the leg 2 over the entire circumference of the leg shaft. As a result, the shape of the hole is made to follow the shape of the cross-sectional outline of the leg 2, and when the leg 2 is inserted into the through hole Pa that allows the leg 2 to be inserted with a small gap, the head is located on the front side of the insertion. The part 1 is caught and brought into contact with the object P to be fastened.

  The elastic engagement pieces 3 are formed on two wide side surfaces 2b and 2b of the leg portion 2, respectively. In the illustrated example, each of the multi-stage elastic engagement pieces 3 is formed to have a substantially rectangular plate shape. The elastic engagement piece 3 is integrally connected to the wide side surface 2b so that one side portion along the length direction extends along the left and right sides of the wide side surface 2b, and protrudes outward from the wide side surface 2b. Has been. In the illustrated example, the elastic engagement pieces 3 are formed in five steps on each of the two wide side surfaces 2 b and 2 b of the leg portion 2. Between the adjacent elastic engagement pieces 3, a substantially equal interval is provided between the steps. Each elastic engagement piece 3 is protruded obliquely from the leg 2 so as to approach the head 1 side toward the other side along the length direction, that is, the protruding end 3a. . The elastic engagement piece formed on one of the protruding end 3a of the elastic engagement piece 3 formed on one of the two wide side surfaces 2b of the leg portion 2 and the two wide side surfaces 2b of the leg portion 2 3 is larger than the distance between the hole edge of the through hole Pa facing one of the wide side surfaces 2b and the hole edge of the through hole Pa facing the other side of the wide side surface 2b. Slightly larger.

  On the other hand, the moderation creating element 4 is formed on two narrow side surfaces 2a and 2a of the leg 2, respectively. In the illustrated example, the moderation creating element 4 is formed on the front side of the elastic piece 5 that extends along the leg axis that positions the free end 5 a in the vicinity of the head 1.

  In the example shown in the drawing, the moderation creating part 4 is biased toward the corner 2c where one of the two narrow side faces 2a, 2a and one of the two wide side faces 2b, 2b are in contact with each other. The other of the two narrow side surfaces 2a, 2a and the other of the two wide side surfaces 2b, 2b are formed at positions offset to the corners 2c where they contact each other. The narrow side surface 2a is provided with a first vertical groove 5b formed with an interval corresponding to the width of the elastic piece 5 between the corner 2c, an upper end of the first vertical groove 5b, and the corner. A transverse groove 5c is formed between the portion 2c and the wide side surface 2b and the second longitudinal groove 5d having the same length as the first longitudinal groove 5b in the vicinity of the corner 2c. The upper end of the second vertical groove 5d communicates with the horizontal groove 5c. The second vertical groove 5d has a depth reaching the bottom of the first vertical groove 5b. In the illustrated example, the elastic piece 5 is formed by the first and second vertical dividing grooves 5b, 5d and the horizontal dividing groove 5c, and a deformation gap 5e of the elastic piece 5 is formed on the back side of the elastic piece 5. I am letting.

  The moderation creating engagement portion 4 has a mountain shape raised on the front side of the elastic piece 5, and the head 1 side sandwiching the top portion 4 a is an engagement surface 4 b, and the top portion 4 a and the elastic piece 5 A slope surface 4c is formed between the base portion and the base portion. In the illustrated example, the engagement surface 4b of the moderation creating element 4 is located below the protruding end 3a of the uppermost elastic engagement piece 3 of the multi-stage elastic engagement piece 3.

  The clip C elastically restores the elastic engagement piece 3 that has come out of the through hole Pa by the insertion of the leg portion 2 out of the multi-stage elastic engagement pieces 33, and between this and the head 1. Since the fastening object P is clamped, a single clip C can be used for fastening a plurality of types of fastening objects P having different thicknesses. Since the elastic engagement piece 3 is protruded obliquely from the leg portion 2 so as to approach the head 1 side toward the protruding end 3a, the elastic engagement piece 3 is easily deformed during the insertion, while the through hole Pa. The movement of the leg part 2 in the direction to escape from the head is effectively prevented. Further, the moderation sensation creating engagement portion 4 is fastened at a position where the leg portion 2 has been completely inserted into the through hole Pa, that is, at a position where the head 1 is brought into contact with the fastening object P on the near side of the insertion. Since it can be engaged with the attachment target P side, the leg 2 is completely inserted through the through hole Pa to the position where the attachment target P is properly sandwiched between the head 1 and any elastic engagement piece 3. It can be made to be recognized by the operator of this insertion. That is, when the sense of engagement of the moderation feeling creation engagement portion 4 does not occur, the operator can recognize that the leg portion 2 has not been inserted to the position. In the illustrated example, the process of inserting the leg 2 through the through hole Pa of the fastening object P whose thickness is made smaller than the distance between the head 1 and the engagement surface 4b of the moderation creating engagement part 4. Then, the slope surface 4c is brought into contact with the object P to be fastened, and the elastic piece 5 is once bent inward, and thereafter, the top portion 4a of the moderation sensation creating engagement portion 4 is passed through the through hole. The elastic piece 5 can be deflected back at the position where it has come out of Pa, and the engagement surface 4b can be engaged with the hole edge of the through hole Pa on the insertion destination side.

  FIGS. 2 to 5 show an example in which the clip C described above is used as a clip body C ′, and the clip C is composed of two parts of the clip body C ′ and the spacer body S combined therewith. Yes.

  The spacer body S includes a base portion 6 having a size that does not enter the through hole Pa and an insertion portion 7 that can be inserted into the through hole Pa. At the same time, it is configured as a hollow body through which the leg 2 of the clip body C ′ can be inserted from the base 6 side. In addition, an open portion 7a from which the elastic engagement piece 3 of the clip body C 'is projected is formed on the side portion of the insertion portion 7 of the spacer body S.

  In the illustrated example, the insertion portion 7 of the spacer body S has a cross-sectional outline shape in a direction orthogonal to the insertion direction so as to follow the shape of the through hole Pa having a substantially rectangular hole shape. . That is, the insertion part 7 of the spacer body S has two width side parts 7b and 7b and two length side parts 7c and 7c. The two length side portions 7c and 7c are opened except for the edge portions, and the open portion 7a having a rectangular window shape is formed on the length side portion 7c. In addition, a rectangular opening 7d is formed above and below the spacer body S, respectively. The base portion 6 is constituted by a flange portion 6a projecting outward from the length side portion 7c at a location between the one opening portion 7d and the opening portion 7a of the spacer body S.

  The distance between the inner surfaces of the pair of width side portions 7b, 7b of the spacer body S is the top of the moderation creating engagement portion 4 formed on the two narrow side surfaces 2a, 2a of the clip body C ′. It is slightly smaller than the distance between 4a. At the same time, the pair of width side portions 7b and 7b of the spacer body S are respectively engaged with the moderation creating engagement portion 4 at a position where the leg portion 2 of the clip body C ′ is completely inserted into the through hole Pa. An engaged portion 8 to be joined is formed. In the illustrated example, the engaged portion 8 is configured as a through hole that penetrates the width side portion 7b of the spacer body S inward and outward.

  In this embodiment, a sense of moderation is created in a state where the leg 2 is inserted through the insertion part 7 of the spacer body S to a predetermined position on the leg end side of the leg 2 of the clip body C ′. An engagement claw 9 is formed between the engagement portion 4 and the spacer body S so as to sandwich the spacer body S up and down. In the illustrated example, the engaging claws 9 projecting from the side surface 2a are formed on two narrow side surfaces 2a and 2a of the leg portion 2 of the clip body C '. And the distance between this engaging claw 9 and the top part 4a of the said moderation feeling creation engaging part 4 is made to correspond substantially with the distance between the two openings 7d of the spacer body S, 7d. . The distance between the two engaging claws 9, 9 is slightly larger than the distance between the inner surfaces of the pair of width side portions 7b, 7b of the spacer body S.

  The distance between the two width side portions 7b, 7b of the spacer body S is substantially equal to the distance between the two narrow side surfaces 2a, 2a of the leg portion 2 of the clip body C ′. The insertion of the spacer body S into the insertion part 7 of the leg part 2 of C ′ is performed by the clip body from the opening part 7d on the base part 6 side of the spacer body S in a direction facing the width side part 7b and the narrow side face 2a. This is done by inserting the leg 2 into the spacer body S with the leg end side of the leg 2 of C ′ first. And this insertion is permitted by slightly extending the distance between the inner surfaces of the pair of width side portions 7b, 7b of the spacer body S mainly by elastic deformation by the contact of the engaging claws 9. When the engagement claw 9 of the leg portion 2 of the clip body C ′ is inserted to the position where the engagement claw 9 comes out of the insertion portion 7 of the spacer body S, the spacer body S is elastically restored to engage with the engagement claw 9 and create a sense of moderation. The spacer body S is sandwiched between the portion 4 and the top and bottom. Thus, in this embodiment, the clip body C ′ and the spacer body S can be temporarily assembled before being inserted into the through hole Pa of the object P to be fastened. In this temporarily assembled state, a part of the elastic engagement piece 3 of the clip body C ′ protrudes outward from the open portion 7a of the spacer body S, and the elastic engagement is located on the head 1 side of the clip body C ′. A part of the piece 3 is positioned in an elastically deformed state in the opening 7d on the base 6 side of the spacer body S. (Fig. 4)

  In the clip C composed of the clip body C ′ and the spacer body S, the leg portion 2 of the multi-stage elastic engagement piece 3 is inserted through the open portion 7a of the spacer body S. The elastic engagement piece 3 that has come out of the hole Pa can be elastically restored and the object P to be clamped can be held between the elastic engagement piece 3 and the head 1. Therefore, a single clip C can be used for fastening a plurality of types of fastening objects P having different thicknesses. Further, at the position where the leg portion 2 is completely inserted into the through hole Pa, that is, the position where the head portion 1 is brought into contact with the fastening object P on the near side of the insertion, the moderation feeling creation engaging portion 4 is set as a spacer. Since it can be engaged with the engaged portion 8 of the body S, the leg portion 2 is inserted into the through hole Pa to the position where the fastening object P is properly sandwiched between the head 1 and any elastic engagement piece 3. This insertion operator can recognize whether or not the insertion has been completed. In the example shown in the drawing, a sense of moderation is created in a process in which the insertion part 7 of the spacer body S is inserted into the through hole Pa of the fastening object P from the temporarily assembled state and then the leg part 2 is completely inserted into the through hole Pa. The slope surface 4c of the engaging portion 4 is brought into contact with the inner surface of the width side portion 7b of the spacer body S so that the elastic piece 5 is once bent inward. The elastic piece 5 is bent back at a position where the top portion 4a of the joint portion 4 enters the engaged portion 8, and the moderation sensation creating engagement portion 4 is inserted into and engaged with the engaged portion 8. (Fig. 5)

  The provision of this characteristic to the portion to be provided with the elastic deformation characteristic in the clip C described above can be easily ensured by using the clip C as a synthetic resin molded product.
