Abstract

<P>PROBLEM TO BE SOLVED: To provide a clip, temporarily fastening an exterior part with small force, and surely fixing the exterior part to a mounting panel. <P>SOLUTION: Even if a pin 20 is not used, the force for holding a retainer 10 is already obtained by the clamping force clamping a body panel 14 and the retainer 10 by a claw part 24 and a flange part 26, so it will be sufficient that the holding force obtained using the pin 20 is small. Therefore, it is not necessary to flare the claw part 24 by an insert part 21 and to bring the insert part 21 into contact with the inner wall of the leg body 22A and bulge the leg body 22a, thereby heightening the holding force. That is, according to the invention, although the insert force for inserting the pin 20 is small, the holding force for holding the retainer 10 can be secured enough to surely fix the retainer 10 to the panel body 14. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a clip used when mounting a bumper of a vehicle.

  The bumper of the vehicle is fixed to the mounting panel via a clip. For example, in Patent Document 1, after the grommet is locked in the mounting hole of the mounting panel, the mounting hole of the exterior component (corresponding to the bumper) is aligned with the mounting hole, and the pin is connected to the mounting hole of the exterior component and the mounting panel. Is inserted into the grommet and the exterior part is fixed to the mounting panel.

  Here, an annular protrusion is provided on the outer peripheral surface of the pin, and a concave fitting portion is provided below the claw portion that is engaged with the attachment hole of the attachment panel on the opposing inner wall of the grommet. Yes. The pin is temporarily fixed to the grommet by fitting the annular protrusion to the concave fitting portion. The fitting force between the annular protrusion and the concave fitting portion (the fitting force between the pin and the grommet) is a holding force for holding the exterior part.

  For this reason, if the fitting force between the pin and the grommet is low, the pin is easy to insert, but the holding force becomes small, and if the holding force is increased, the pin becomes difficult to insert.

Therefore, the pins are divided into those for temporary fixing and those for temporary fixing. Temporary fixing pins are temporarily fixed to the mounting panel using temporary fixing pins at predetermined positions, and permanent fixing pins are used at the remaining positions. Securely fix the exterior parts. Further, in some cases, the holding force of the exterior component is enhanced by removing the temporary fixing pin from the grommet and re-fixing it with the final fixing pin.

  Hereinafter, a clip according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the retainer 10 can be fixed to the body panel 14 via a clip 12. The retainer 10 is provided with a fitting recess 10A, and a claw portion 11 projects into the fitting recess 10A. On the other hand, a fitting convex portion 16A protrudes from the back surface of the bumper 16, and a through hole 17 is formed in the fitting convex portion 16A.

  When the fitting projection 16A of the bumper 16 is inserted into the fitting recess 10A of the retainer 10 with the retainer 10 fixed to the body panel 14, the nail of the fitting recess 10A is inserted into the through hole 17 of the fitting projection 16A. The part 11 is locked and the bumper 16 is fixed to the retainer 10. As a result, the bumper 16 is fixed to the body panel 14 via the retainer 10.

  Here, the clip 12 will be described in detail.

  As shown in FIGS. 2 to 5, the clip 12 includes a grommet 18 and a pin 20. 4B is a cross-sectional view taken along the line AA in FIG. 4A, FIG. 5A is a cross-sectional view taken along the line BB in FIG. 4A, and FIG. It is sectional drawing of CC line of FIG. 4 (A). Further, in the figure, when an arrow UP and an arrow DOWN are shown, it indicates an upward direction and a downward direction, respectively, and when expressed in an up and down direction, it corresponds to each arrow.

  First, the grommet 18 will be described. The grommet 18 includes an annular flange portion 26 having a larger outer diameter than the mounting hole 10 </ b> B of the retainer 10. From the lower surface of the flange portion 26, the claw portion 24 and the leg body 22A facing each other hang down, and the separation distance of the inner wall of the facing leg body 22A is larger than the separation distance of the inner wall of the facing claw portion 24. is doing.

  The claw portion 24 is formed shorter than the leg body 22A, and a slit 34 is provided between the leg body 22A and cantilevered independently of the leg body 22A so as to be elastically deformable. Further, the front end portions of the leg bodies 22A are connected to each other, and the leg bodies 22A and the claw portions 24 constitute a substantially rectangular bag body 22, and an opening 36 is provided below the claw portions 24. .

  The interval between the outer walls of the leg 22A is a width that can be inserted into the attachment hole 10B of the retainer 10 and the attachment hole 14A of the body panel 14, and the interval between the outer walls of the claw portion 24 is the same as the attachment hole 10B and the attachment hole. It is wider than 14A.

  For this reason, when the bag body 22 is inserted into the mounting hole 10B of the retainer 10 and the mounting hole 14A of the body panel 14, the claw portion 24 comes into contact with the peripheral portion of the mounting hole 10B. When the grommet 18 is pressed from this state, the claw portion 24 is compressed and narrowed by the peripheral edge portion of the mounting hole 10B.

  Then, when the upper surface 24A of the claw part 24 passes through the attachment hole 10B and the attachment hole 14A and reaches the opening 36, the claw part 24 is widened and the upper surface 24A comes into contact with the peripheral part of the attachment hole 14A (FIG. 4). (See (B)). In this state, the body panel 14 and the retainer 10 are sandwiched between the flange portion 26 and the claw portion 24, and the retainer 10 is held and temporarily fixed to the body panel 14.

  Engaging convex portions 28 and 30 (see FIG. 5A) are respectively provided along the inner wall side central portion of the leg 22A of the grommet 18 and the inner wall side central portion of the claw portion 24 along the axis of the grommet 18. It protrudes and guides a pin 20 (described later) to be inserted into the grommet 18. Further, a locking claw 32 protrudes from the tips (see FIG. 4B) of both end portions on the inner wall side of the claw portion 24.

  On the other hand, the pin 20 is provided with a rectangular flange portion 38. A pair of side walls 20A and 20B hang down from the lower surface of the flange portion 38, the side walls 20A and the side walls 20B face each other, The insertion part 21 which comprises substantially square column shape is comprised.

  By the way, on the upper surface of the flange portion 26 of the grommet 18, an annular projecting portion 26 </ b> A is projected, and the flange portion 38 of the pin 20 with the insertion portion 21 inserted into the bag body 22 of the grommet 18. However, surface contact is possible with the projecting portion 26A of the flange portion 26 of the grommet 18. Therefore, the movement of the pin 20 with respect to the grommet 18 is restricted in a state where the flange portion 38 is in surface contact with the protruding portion 26A (see FIGS. 4A and 4B).

  Further, as shown in FIGS. 2 and 5A, the engagement recesses 42 and 44 are provided in the central portion of the outer wall of the side walls 20A and 20B along the axial direction of the pin 20, and the engagement recess 42 and 44 are shorter than the side walls 20A and 20B. The claw portion 24 of the grommet 18 and the engaging convex portions 30 and 28 formed on the peripheral wall 22A engage with the engaging concave portions 42 and 44, respectively, and the pin 20 is guided with respect to the grommet 18.

  Furthermore, a locking leg 46 is formed at the tip of the engaging recess 42, and a locking claw 48 projects from the tip of the locking leg 46. The locking leg 46 can be elastically deformed, and the locking claw 48 projects from the same plane of the side wall 20A. The locking leg 46 can be inserted into an opening 36 formed in the lower part of the claw 24 of the grommet 18.

  When the insertion portion 21 of the pin 20 is inserted into the bag body 22 of the grommet 18, the locking claw 48 of the locking leg 46 abuts on the engagement convex portion 30 formed at the central portion on the inner wall side of the claw portion 24. . When the pin 20 is pressed in this state, the locking leg 46 is compressed and narrowed to pass between the claw portions 24.

  When the locking claw 48 of the locking leg 46 reaches the opening 36, the locking leg 46 is widened and the locking claw 48 is locked to the lower part of the claw part 24 as shown in FIG. 6. As a result, the pin 20 is secured to the grommet 18 and temporarily secured.

  On the other hand, as shown in FIGS. 3 (A), 5 (A), and 5 (B), the outer wall of the side wall 20B extends from the base portion to the distal end portion, and the outer walls face each other straight. It is made not to contact the inner wall of the leg 22A.

  Further, as shown in FIG. 3B, an inclined portion 40 in which the outer walls gradually spread from the tip portion is formed at the tip of the side wall 20A. A step portion 40A is provided at the end of the inclined portion 40, and the claw portion 24 pushed and spread by the inclined portion 40 is locked when reaching the step portion 40A.

  In a state where the claw portion 24 is locked to the step portion 40A, the flange portion 38 of the pin 20 comes into surface contact with the protruding portion 26A of the grommet 18. Thereby, the pin 20 is fixed to the grommet 18, and the retainer 10 is fixed to the body panel 14 via the clip 12 constituted by the pin 20 and the grommet 18 (see FIG. 1).

  Incidentally, as shown in FIG. 2, a screw pin 50 can be used for the grommet 18 instead of the pin 20. As shown in FIGS. 7A and 7B, the outer diameter of the screw pin 50 is determined based on the distance between the inner walls of the legs 22A of the grommet 18 (> the distance between the inner walls of the claws 24 facing each other). Is also slightly larger. For this reason, when the screw pin 50 is inserted into the grommet 18, the claw portion 24 is widened by the top of the thread 50 </ b> A of the screw pin 50, and the leg body 22 </ b> A bulges.

  Next, the operation of the clip according to the embodiment of the present invention will be described.

  As shown in FIG. 1, in the present invention, the bag body 22 of the grommet 18 is inserted into the mounting holes 14 </ b> A and 10 </ b> B formed in the body panel 14 and the retainer 10, and the body between the flange portion 26 and the claw portion 24 is inserted. As shown in FIGS. 3A and 3B, the retainer 10 can be temporarily fixed to the body panel 14 by sandwiching the panel 14 and the retainer 10. As described above, the retainer 10 can be temporarily fixed to the body panel 14 without using the pins 20, so that workability is good.

  Further, the insertion portion 21 of the pin 20 is inserted into the bag body 22 with the retainer 10 temporarily fixed to the body panel 14. As shown in FIG. 4 (B) and FIG. 5 (A), the insertion portion 21 of the pin 20 increases the width of the claw portion 24 only by pushing the claw portion 24 from the inside. The clamping force (holding force of the retainer 10 with respect to the body panel 14) for clamping the body panel 14 and the retainer 10 with the claw portion 24 and the flange portion 26 can be increased.

  Here, the movement amount (widening amount) of the claw portion 24 on the free end side can be increased by hanging the claw portion 24 from the flange portion 26 and extending it in a cantilevered manner.

  On the other hand, as shown in FIGS. 3A and 3B, the retainer 10 is held by the clamping force that clamps the body panel 14 and the retainer 10 between the claw portion 24 and the flange portion 26 without using the pin 20. Since the holding force has already been obtained, the holding force obtained by using the pin 20 may be small.

  Therefore, as shown in FIGS. 4B and 5A, it is only necessary to spread the claw portion 24 by the insertion portion 21, and the insertion portion 21 is brought into contact with the inner wall of the leg body 22A to swell the leg body 22A. It is not necessary to raise (push out) and further increase the holding power.

  That is, according to the present invention, although the insertion force for inserting the pin 20 is small, a sufficient holding force for holding the retainer 10 can be ensured, and the retainer 10 is securely fixed to the body panel 14. Can do.

  Further, the retainer 10 can be held in a well-balanced manner by arranging the side walls 20A of the pins 20 and the side walls 20B facing each other.

  Further, as shown in FIGS. 7A, 7B and 8, by using a screw pin 50 instead of the pin 20, the screw pin 50 is also brought into contact with the inner wall of the leg 22A. The holding force for holding the retainer 10 can be further increased. For this reason, when the retainer 10 is fixed to the body panel 14, the holding force of the retainer 10 can be changed depending on the position of the retainer 10 using the pin 20 and the screw pin 50.

  By making the grommet 18 the bag body 22, the leg body 22 </ b> A is hardly deformed, the state where the body panel 14 and the retainer 10 are held is maintained, and the holding force for fixing the retainer 10 to the body panel 14 is increased. be able to.

  Moreover, since it is possible to insert the pin 20 or the screw pin 50 into one grommet 18, it is not necessary to form a grommet for the pin 20 or the screw pin 50, respectively, thereby reducing the die cost of the grommet. Can do.

  On the other hand, when the insertion portion 21 of the pin 20 is inserted into the grommet 18, the locking leg 46 of the claw portion 24 passes through the opening 36 so that the locking claw 48 is locked to the distal end portion of the claw portion 24. By doing so, the pin 20 can be temporarily fixed to the grommet 18. Thereby, the pin 20 is not easily detached from the claw portion 24 in a temporarily fixed state of the pin 20.

  In addition, this form is an Example to the last, and it cannot be overemphasized that it can change suitably in the range which does not deviate from the main point of this invention. For example, although the front ends of the leg bodies 22A are connected to each other, the shapes may not be connected. Moreover, although the screw pin 50 was used, it is only necessary to be able to push and spread the claw portion 24 and the leg body 22A. Therefore, the present invention is not limited to this, and for example, a knurled pin may be used.

  Furthermore, here, the separation distance of the inner wall of the leg body 22A of the bag body 22 is made larger than the separation distance of the inner wall of the claw portion 24 so that the insertion portion 21 is not brought into contact with the inner wall of the leg body 22A. Since it is not necessary for the leg 22A to be pushed and expanded with the insertion part 21 inserted into the body 22, the insertion part 21 and the leg 22A may contact each other, and the insertion part 21 is inserted into the bag body 22. In the process of inserting, the leg 22A may be spread.

  Moreover, although the insertion part 21 of the pin 20 was made into substantially square shape, since the leg body 22A should not be pushed and expanded in the state which inserted the insertion part 21 in the bag body 22, it does not restrict to this shape.
