FIG. 1 is a perspective view of an example fastener 10. FIG. FIG. 1(a) shows the fastener 10 viewed from above, and FIG. 1(b) shows the fastener 10 viewed from below. The fastener 10 is attached to the attachment hole of the attachment member. The mounting member may be, for example, a vehicle body panel or a door panel, and has a mounting hole formed in the process of mounting the vehicle component. A fastener 10 is provided to block the mounting hole of the mounting member. The fastener 10 is temporarily removed for repairing an in-vehicle component or the like. The mounting hole of the mounting member is preferably an elongated hole, but may be a square hole or a round hole.

The fastener 10 has a first plate portion 14 , a second plate portion 16 and a hinge portion 18 . The hinge portion 18 is formed to be thin and flexible, and integrally connects the first plate portion 14 and the second plate portion 16 . The bending of the hinge portion 18 causes the first plate portion 14 and the second plate portion 16 to rotate around the hinge portion 18 .

The first plate portion 14 has a first locking claw 20 , an elastic claw 26 , a first overlapping portion 28 and a first thick plate portion 34 . The second plate portion 16 has a second locking claw 22 , a hole portion 24 , a second overlapping portion 30 , a projecting portion 32 and a second thick plate portion 36 .

The first locking claw 20 is erected from the rear surface of the first thick plate portion 34 of the first plate portion 14 , and the tip protrudes in a direction away from the second plate portion 16 . The first overlapping portion 28 is located closer to the hinge portion 18 than the first locking claw 20 is. The first thick plate portion 34 is thicker than the first overlapping portion 28 and is connected to the hinge portion 18 . The first overlapping portion 28 is connected to the first thick plate portion 34 and extends away from the hinge portion 18 . The first thick plate portion 34 and the first overlapping portion 28 are formed in a flat plate shape and are flatly connected on the surface side.

That is, the first thick plate portion 34 and the first overlapping portion 28 extend in opposite directions from the hinge portion 18 . As a result, the first thick plate portion 34 and the first overlapping portion 28 swing with the hinge portion 18 interposed therebetween. The elastic claw 26 is erected from the rear surface of the first overlapping portion 28 and formed to be flexible.

The second locking claw 22 of the second plate portion 16 is erected from the back surface of the second thick plate portion 36 of the second plate portion 16 . The second overlapping portion 30 is positioned closer to the hinge portion 18 than the second locking pawl 22 and continues to the hinge portion 18 . The second thick plate portion 36 is formed thicker than the second overlapping portion 30 and is connected to the second overlapping portion 30 . The second overlapping portion 30 and the second thick plate portion 36 are formed in a flat plate shape and are flatly connected to each other on the rear surface side.

The hole portion 24 is formed through the second overlapping portion 30 . The elastic claw 26 of the first plate portion 14 is inserted into and engaged with the edge of the hole portion 24 . The projecting portion 32 is formed on the back surface of the second overlapping portion 30 . The projecting portion 32 is inserted into the mounting hole, contacts the edge of the mounting hole, and stops moving in the width direction. Note that the projecting portion 32 may be formed on the first plate portion 14 as long as it is formed between the first locking claw 20 and the second locking claw 22 .

FIG. 2 shows the fastener 10 in a fully installed state attached to the mounting member 12 . 3 is a cross-sectional view of the fastener 10 shown in FIG. 2 taken along line AA. As shown in FIG. 2, the surface of the fastener 10 is in a state where the first overlapped portion 28 and the second overlapped portion 30 are overlapped when the attachment is completed, and the first plate portion 14 and the second plate portion 16 are evenly distributed. to a flat state.

As shown in FIG. 3, when the mounting is completed, the first locking claw 20 and the second locking claw 22 protrude in opposite directions and are locked to the edges of the mounting hole 12a. Thereby, the fastener 10 is attached to the attachment member 12 .

In addition, the elastic claw 26 engages with the edge of the hole 24 in the attachment completion state. As a result, the first plate portion 14 and the second plate portion 16 are locked, and the rotation around the hinge portion 18 is restricted. That is, the state in which the first locking claw 20 and the second locking claw 22 are locked in the mounting hole 12a is maintained by the engagement of the elastic claw 26 and the hole portion 24, and the fastener 10 is removed from the mounting member 12. is suppressed. In other words, the elastic claw 26 and the penetrating portion 24 are engaged in a state where the first overlapping portion 28 and the second overlapping portion 30 are overlapped, thereby restricting the movement of the first overlapping portion 28 and the second overlapping portion 30 apart. act as a means. The first locking claw 20 and the second locking claw 22 perform the function of locking the mounting hole 12a, and the hole portion 24 and the elastic claw function to restrict the rotation of the first plate portion 14 and the second plate portion 16. 26 can easily make settings according to each function.

The first locking claw 20 and the second locking claw 22 have a shorter erected height than the elastic claw 26, are less likely to bend, and have higher rigidity than the elastic claw 26. - 特許庁As a result, by making the rigidity of the first locking claw 20 and the second locking claw 22 higher than that of the elastic claw 26, the first locking claw 20 and the second locking claw 22 are firmly prevented from slipping out of the mounting hole 12a. However, the standing height of the first locking claw 20 and the second locking claw 22 can be shortened. That is, even if the standing height of the first locking claw 20 and the second locking claw 22 is shortened, a sufficient pull-out force can be ensured.

The hole 24 and the elastic claw 26 are positioned between the first locking claw 20 and the second locking claw 22 in the completed mounting state. As a result, when the fastener 10 is removed from the mounting hole 12a by bending the elastic claw 26 with a tool or the like, the mounting hole 12a is not damaged by the tool or the like because the elastic claw 26 is not engaged with the mounting hole 12a. can be prevented.

The thickness T1 of the first thick plate portion 34 and the second thick plate portion 36 is substantially the same as the thickness T2 of the overlap of the first overlapping portion 28 and the second overlapping portion 30 . This makes it possible to flatten the surface of the fastener 10 when the attachment is completed.

Since the hinge portion 18 is thin and flexible, it can exhibit elastic force in the opposing direction of the first locking claw 20 and the second locking claw 22 when the fastener 10 is mounted in the mounting hole 12a. Can absorb directional rattling.

4A and 4B are diagrams for explaining the process of attaching the fastener 10 to the attachment member 12. FIG. FIG. 4(a) shows the fastener 10 before installation, in which the first plate portion 14 and the second plate portion 16 are substantially perpendicular to each other. The operator aligns the fastener 10 with the mounting hole 12 a and pushes the first plate portion 14 toward the mounting member 12 .

As shown in FIG. 4B, the first plate portion 14 and the second plate portion 16 rotate about the hinge portion 18, and the first locking claw 20 and the second locking claw 22 enter the mounting hole 12a. At the same time, the elastic claw 26 enters the hole 24 .

4(c), the first locking claw 20 and the second locking claw 22 are locked to the edge of the mounting hole 12a, and the elastic claw 26 is engaged to the edge of the hole 24. As shown in FIG. The first overlapped portion 28 and the second overlapped portion 30 overlap each other when the first plate portion 14 and the second plate portion 16 are rotated from the pre-mounting state in which the first plate portion 14 and the second plate portion 16 intersect to the mounting completion state in which they are mounted in the mounting hole 12a. Become. Also, the distance between the first locking claw 20 and the second locking claw 22 is longer in the attached state shown in FIG. 4(c) than in the unattached state shown in FIGS. 4(a) and 4(b). . Also, the distance between the first locking claw 20 and the second locking claw 22 in the pre-mounting state is shorter than the hole diameter of the mounting hole 12a. As a result, the first locking claw 20 and the second locking claw 22 can be locked in the mounting hole 12a by rotating about the hinge portion 18, so that the first locking claw 20 and the second locking claw 22 does not need to bend, and can be shortened to increase rigidity. As a result, the standing height of the first locking claw 20 and the second locking claw 22 can be shortened, and the protrusion to the rear side of the mounting member 12 can be reduced.
