Description

  The present invention relates to a clip and a part mounting structure used when attaching parts such as vehicle interior parts.

  Conventionally, when attaching a vehicle interior part such as an assist grip to a vehicle body side panel, a clip is attached to a base that holds the grip body of the assist grip in a swingable manner, and a resin cap is provided in the internal space of the clip. A structure is known in which a clip is inserted into a mounting hole and an elastic locking portion is locked in the mounting hole after the leg portion is inserted (for example, Patent Documents 1 and 2).

  In the clip in Patent Document 1, the tip of the elastic locking portion that locks in the mounting hole is divided, and the insertion load of the clip can be reduced. Further, stress concentration at the center of the mounting hole due to the clip allowance can be dispersed, so that deformation of the mounting hole can be suppressed and the clip can be prevented from coming out of the mounting hole.

  However, if the tip of the elastic locking portion is divided, the contact area with the leg portion of the cap made of resin is reduced. For this reason, the leg portion is easily deformed, and the clip may come out of the mounting hole. In addition, the rigidity of the clip itself also decreases.

  On the other hand, as for the clip shown by patent document 2, the front-end | tip of the elastic latching | locking part is not divided | segmented. For this reason, the contact area to the leg part of an elastic locking part increases, and the deformation | transformation of the leg part by a clip can be reduced. However, stress concentration tends to occur at the center of the mounting hole due to the clip allowance, so that the mounting hole may be deformed and the clip may come out of the mounting hole. Further, the rigidity of the clip itself is also unsatisfactory.

  The present invention has been made in view of such circumstances, and can reduce the deformation of the leg portion due to the clip and suppress the deformation of the mounting hole, thereby preventing the clip from coming out of the mounting hole. It is an object of the present invention to provide a mounting structure for clips and parts.

  In order to solve the above-mentioned problems, a clip for mounting a component according to the present invention is a clip for mounting a component used when a component having a base is mounted in a mounting hole of a mounting member, and the clip is between a pair of side walls. The pair of side walls have an internal space, the pair of side walls are connected to each other at the distal end portion, and the base end portion has an opening communicating with the internal space. The elastic locking portion is connected to the side wall at one end, and the other end is a free end closer to the inner space than the other end. A recess that has a recess that is recessed and locked to the mounting hole, and a protruding portion that protrudes outward from the recess, and that does not contact the periphery of the mounting hole when the component is mounted in the mounting hole. On the sloped part from the top of the overhang to the recess It is characterized in.

  In the clip for mounting components according to the present invention, it is preferable that the escape portion is a recess formed so as to protrude toward the inner space.

  Further, the component mounting structure of the present invention includes a component having a base, a mounting member having a mounting hole, an internal space between a pair of side walls, and the pair of side walls connected to each other at a distal end portion. A clip having an opening communicating with the internal space, and provided with an elastic locking portion locked to a peripheral edge of the mounting hole and a holding portion held by the base on each of the pair of side walls; A cap having a cover that covers the end and a leg that is inserted into the internal space from the opening, and holds the clip holding portion on the base, and the clip is inserted into the mounting hole and elastically locked. A part formed by attaching a part to an attachment member by locking the part to the periphery of the attachment hole, covering the base end part of the clip with the cover part of the cap, and fitting the leg part into the internal space from the opening of the clip Mounting structure The clip elastic locking portion has one end connected to the side wall, the other end is a free end, and is recessed toward the inner space side than the other end, and is retained in the mounting hole. And an overhanging portion that protrudes outward from the depression, and the part that is attached to the attachment hole is inclined so that the escape portion that does not contact the periphery of the attachment hole extends from the top of the extension to the depression. It is characterized by having in the part.

  The clip for mounting a component according to the present invention includes a relief portion that does not come into contact with the peripheral edge of the mounting hole in a state where the component is mounted in the mounting hole on the inclined portion extending from the top of the protruding portion of the elastic locking portion to the recess. . Therefore, when a load is applied to the clip in the part removal direction, the stress applied from the peripheral edge of the mounting hole to the recess is distributed to the left and right of the recess with the escape portion interposed therebetween. For this reason, the stress concentration to the center part of the mounting hole can be suppressed. That is, by providing the relief portion in the elastic locking portion, it is possible to effectively prevent the clip from coming out of the attachment hole while suppressing the deformation of the attachment hole.

  On the other hand, the inner peripheral surface (convex surface on the inner space side) of the recess is in contact with the leg of the cap with the entire width of the recess. Therefore, as compared with the case where the tip of the hollow portion is divided, the deformation of the leg portion of the cap made of resin is suppressed, and the clip can be prevented from coming out of the mounting hole.

  In the present invention, when the relief portion is a concave portion protruding toward the inner space, for example, a bead shape, the bead portion also serves as a reinforcing rib, so that the rigidity of the clip itself can be increased.

  An embodiment according to the present invention will be described with reference to the drawings. FIG. 1 is a front view of an attachment structure in which an assist grip is attached to a vehicle side panel. FIG. 2 is an exploded perspective view of the mounting structure. As shown in FIGS. 1 and 2, the assist grip 1 is attached to the vehicle-side panel 2 using a clip 3 and a cap 4.

  The assist grip 1 has a grip body 10 and a base 11 that is provided at both ends of the grip body 10 and supports the grip body 10 so as to be rotatable. Both ends of the grip body 10 have recesses 10 a that accommodate the base 11. A shaft hole 10b is opened in the side wall of the recess 10a. The grip body 10 is rotatably supported with respect to the base 11 by inserting the shaft 12 into the shaft hole 10 b and the hole of the bearing portion 11 a provided in the base 11. A spring 13 is disposed between the bearing portion 11a and the shaft hole 10b to bias the grip body 10 in a direction in which the recess 10a approaches the base 11. One end 13a of the spring 13 is locked to the locking portion 10c of the recess 10a, and the other end 13b is locked to the locking portion 11n of the bearing portion 11a. The base 11 is a part fixed to the vehicle panel 2 using the clip 3 and the cap 4 as will be described later. The grip body 10 and the base 11 are molded by injecting a resin material into a mold.

  FIG. 3 is a cross-sectional view of a principal part of the assist grip mounting structure. In FIG. 3, the downward direction on the paper surface is the insertion direction, the upward direction on the paper surface is the exit direction, and the horizontal direction on the left and right is the depth direction of the internal space of the clip. A direction toward the center of the depth between the pair of side walls of the clip is referred to as a depth center direction G, and a direction toward the outside of the depth of the side wall of the clip is referred to as a depth outer direction H. The width in the depth direction of the internal space between the side walls of the clip is referred to as a depth width D. The same applies to FIGS. 8, 9, and 11 to 13.

  As shown in FIG. 3, the vehicle side panel 2 has a surface panel 21 exposed in the vehicle compartment and an internal panel 22 interposed between the surface panel 21 and the body. The surface panel 21 is obtained by attaching a skin material to a ceiling panel of a vehicle. A mounting hole 2a is formed through the front panel 21 and the inner panel 22 at a position where the base 11 is mounted. Since the opening diameter of the front panel through-hole 2b of the mounting hole 2a is larger than that of the inner panel through-hole 2c, the peripheral edge 2d of the inner panel through-hole 2c is exposed to the front panel through-hole 2b.

  As shown in FIGS. 3 and 4, the clip 3 has a U-shaped cross section. The clip 3 has a pair of side walls 3e on both sides of the internal space 3b. At the tip 3g of the clip 3, a pair of side walls 3e are curved and connected in a U shape. At the base end portion 3d of the clip 3, the side wall 3e is not connected and has an opening 3c communicating with the internal space 3b. The clip 3 is inserted into the mounting hole 2a of the vehicle side panel 2 in the longitudinal direction. The side wall 3e of the clip 3 has a pair of elastic locking portions 3a at positions facing each other in the direction orthogonal to the longitudinal direction, that is, in the depth direction of the internal space 3b.

  The elastic locking portion 3a has one end 3s connected to the vicinity of the tip 3g of the side wall 3e, and the other end 3q being a free end. The elastic locking part 3a is recessed in the vicinity of the end part 3q of the free end, recessed toward the inner space 3b side from the end part 3q and projecting outward from the recessed part 3k. 3m. The recess 3k is curved in an arc shape and is recessed in the depth inside direction G with respect to the flat surface 3h of the side wall 3e in a free state.

  A bead 3r is formed between the protruding portion 3m and the recess 3k of the elastic locking portion 3a so as to protrude in the depth direction G along the longitudinal direction of the elastic locking portion 3a. The bead 3r is formed from the top 3t of the overhanging portion 3m to the boundary between the inclining portion 3z and the indenting portion 3k via the inclined portion 3z on the depression 3k side of the overhanging portion 3m.

  The bead 3r is formed at the center of the lateral width C of the side wall 3e. The bead 3r is an escape portion in which the clip allowance does not come into contact with the peripheral edge 2d of the attachment hole 2a in a state where the clip 3 is attached to the attachment hole 2a.

  Further, a step portion 3 f as a holding portion held by the base 11 is provided on the side of the base end portion 3 d of the side wall 3 e of the clip 3 relative to the elastic locking portion 3 a. The step portion 3f is a portion formed by refracting the side wall 3e in the depth outward direction H. The clip 3 is formed by punching and bending a metal plate.

  As shown in FIGS. 3 and 5, the cap 4 has a cover portion 4 a that covers the base end portion 3 d of the clip 3, and a leg portion 4 b that is inserted into the internal space 3 b from the opening 3 c of the clip 3 and extends in the insertion direction. . The cover 4a is curved in a U-shaped cross section so as to cover the upper surface and side surfaces of the cap holding wall 11c formed on the upper portion of the base 11. The leg part 4b has four support | pillars 4c located in the four corners of a rectangle, and a pair of clamping part 4d which connects between the adjacent support | pillars 4c planarly. A portion of the leg portion 4b that faces the side wall 3e of the clip 3, that is, an outer surface of the leg portion 4b has a pressure contact portion 4e that presses against the side wall 3e. In addition, as shown in FIG. 10, the latching convex part 4g is formed in the inner surface of the cover part 4a of the cap 4. As shown in FIG. The cap 4 is molded by injecting a resin material into a mold.

  As shown in FIGS. 3, 6, and 7, the base 11 of the assist grip 1 protrudes upward from the frame portion 11 f and a frame portion 11 f having a rectangular clip holding hole 11 b into which the clip 3 is inserted. And a cap holding wall 11c. The cap holding wall 11c has a shape along the inner side surface of the cover 4a of the cap 4, and holds the cap 4 in contact with the inner side surface. A bearing portion 11a that rotatably supports the grip body 10 is integrally fixed to a rear end portion of the cap holding wall 11c.

  Furthermore, the base 11 has an abutment rib 11d that protrudes below the frame portion 11f. The abutment rib 11d is a restricting portion that restricts the movement of the clip 3 in the removal direction when the clip 3 is inserted into the mounting hole 2a of the vehicle-side panel 2. The contact rib 11d is disposed at the center of the clip holding hole 11b and divides the clip holding hole 11b into two. The contact rib 11d has a flat plate shape, and the lateral width B of the contact rib 11d is substantially the same as the lateral width C of the clip 3 (see FIG. 10). As shown in FIG. 6, the tip 11e of the contact rib 11d is chamfered to reduce the lateral width B. As shown in FIG. 10, the tip 11 e is inserted into a slit 3 j that opens at the tip 3 g of the clip 3, and the abutment rib 11 d is positioned approximately at the center of the depth width D of the internal space 3 b of the clip 3. Yes.

  In attaching the assist grip 1 to the vehicle side panel 2 using the clip 3 and the cap 4, first, as shown in FIG. 8, the side wall 3e of the clip 3 is compressed in the depth center direction G, and the base end portion 3d. The depth width D of the internal space 3b is narrowed. In this state, the clip 3 is inserted into the clip holding hole 11b of the base 11 from the base end 3d side. The side wall 3e of the clip 3 is inserted from the lower side of the clip holding hole 11b while being in sliding contact with the contact rib 11d of the base 11. And the step part 3f formed in the base end part 3d of the clip 3 is latched to the upper periphery 11m of the clip holding hole 11b. At this time, the tip 11e of the abutment rib 11d is inserted into the slit 3j that opens to the tip 3g of the clip 3, and the tapered or stepped locking portion 11h near the tip 11e of the abutment rib 11d becomes the slit 3j. (See FIG. 10). In this way, the clip 3 is held on the base 11, and the abutment rib 11 d is positioned at the approximate center of the depth width D of the internal space 3 b of the clip 3.

  Next, as shown in FIGS. 9 and 10, the leg portion 4 b of the cap 4 is temporarily inserted into the internal space 3 b from the opening 3 c of the base end portion 3 d of the clip 3. At this time, as shown in FIG. 10, the locked convex portion 4g protruding on the inner surface of the cover portion 4a of the cap 4 is locked to the outer edge 11g of the cap holding wall 11c of the base 11, and is inserted at this position. Is temporarily stopped. The leg portion 4b is inserted up to the portion where the elastic locking portion 3a is located in the internal space 3b of the clip 3, but as shown in FIG. 9, the inner space 3b of the portion where the elastic locking portion 3a is located has a depth. A gap 3p remains in the direction. Therefore, the elastic locking portion 3a can be easily deformed in the depth direction of the internal space 3b.

  Next, as shown in FIGS. 11 and 2, the base 11 is disposed in the recess 10 a of the grip body 10. The shaft 12 is inserted into the shaft hole 10 b of the recess 10 a and the bearing portion 11 a of the base 11, and the shaft 12 is inserted into the hole of the cylindrical collar 14. A spring 13 is disposed between the bearing portion 11a and the shaft hole 10b. One end 13a of the spring 13 is locked to the locking portion 10c of the recess 10a, and the other end 13b is locked to the locking portion 11n of the bearing portion 11a. Accordingly, the grip body 10 is attached to the base 11 and the grip body 10 is biased to the base 11 by the spring 13. And the edge part 4k of the cover part 4a of the cap 4 contact | abuts to the inner surface 10d of the recessed part 10a. Thereby, the clip 3, the cap 4, and the grip body 10 are integrally held with respect to the base 11.

  Next, as shown in FIG. 12, the grip body 10 is pressed toward the vehicle side panel 2 side (F1 direction in FIG. 12). As a result, the cap 4 is pushed by the inner surface 10d of the recess 10a of the grip body 10. Further, the cap 4 pushes the base 11 with the locked convex portion 4g (see FIG. 10), and the clip 3 held by the base 11 is inserted into the mounting hole 2a of the vehicle body side panel 2. The peripheral edge 2d of the inner panel penetration 2c is exposed in the mounting hole 2a. Therefore, the elastic locking portion 3a of the clip 3 elastically contacts the peripheral edge 2d, the depth width D of the internal space 3b between the elastic locking portions 3a is reduced, and the overhanging portion 3m of the elastic locking portion 3a It passes through the panel penetration part 2c. After passing through the inner panel penetrating portion 2c, the elastic locking portion 3a brings the depth width D close to the original size by the spring repulsive force of the elastic locking portion 3a. And the hollow part 3k of the elastic latching | locking part 3a is latched by the peripheral edge 2d of the internal panel penetration part 2c with this spring repulsive force. Thereby, the assist grip 1 is temporarily fixed to the vehicle side panel 2.

  Next, as shown in FIG. 13, the cover 4a of the cap 4 is pressed with a load larger than the force F1 at the time of temporary fixing in FIG. 12 in the vehicle side panel 2 side, that is, in the direction F2 shown in FIG. As a result, the locked projection 4g of the cap 4 and the outer edge 11g of the cap holding wall 11c of the base 11 are released, and the cap 4 is further inserted in the insertion direction. The cap holding wall 11c comes into contact with the inner surface of the cover 4a, and the base end 3d side of the clip 3 and the upper side of the base 11 are covered with the cover 4a. Further, the leg 4 b of the cap 4 is inserted into the internal space 3 b of the clip 3. Thereby, the contact rib 11d of the base 11 is clamped by a pair of clamping part 4d formed between the leg parts 4b. Moreover, the clamping part 4d press-contacts to the inner surface of the hollow part 3k of the elastic latching | locking part 3a. That is, as shown in FIGS. 13, 4, and 5, the sandwiching portion 4 d of the leg portion 4 b of the cap 4 abuts on the recess 3 k of the elastic locking portion 3 a of the clip 3, and the elastic locking portion 3 a is deformed. Suppress. Further, the support column 4c of the leg portion 4b of the cap 4 abuts on the flat surface portion 3h of the side wall 3e of the clip 3, and suppresses deformation of the entire clip 3 excluding the elastic locking portion 3a. Thereby, there is no gap in the depth direction of the internal space 3b of the clip 3, and the elastic locking portion 3a is hardly deformed in the depth center direction G of the internal space 3b. And the side wall 3e of the clip 3 and the hollow part 3k of the elastic locking part 3a become difficult to bend in the depth center direction G, and the clip 3 is prevented from coming out of the mounting hole 2a. In this way, the assist grip 1 is permanently fixed to the vehicle side panel 2.

  Next, the effect of the escape portion (bead 3r) in the present embodiment will be described with reference to FIG. 14A and 14B are schematic diagrams for explaining the effect of the escape portion. FIG. 14A is a front view as viewed in FIG. 4 in a state in which the clip 3 is fitted in the mounting hole 2a, and FIG. B partial sectional drawing of B is shown.

  In the present embodiment, a bead 3r protruding in the depth inner direction G is formed in the elastic locking portion 3a of the clip 3. Here, when a load F3 in the pulling direction is applied to the clip 3, the peripheral edge 2d of the mounting hole 2a comes into contact with the elastic locking portion 3a at the boundary 3v between the recessed portion 3k and the inclined portion 3z. However, since the bead 3r that is depressed in the central direction G is formed at the boundary 3v of the elastic locking portion 3a, the left and right widths K except for the bead 3r with the width J become the hooking margin 3y of the clip. That is, the stress applied to the recess 3k from the peripheral edge 2d of the mounting hole 2a is distributed to the left and right across the bead 3r, so that the central portion of the mounting hole 2a is the same as when the recess 3k is divided. It is possible to suppress stress concentration on the surface. Therefore, it is possible to effectively prevent the clip 3 from coming out of the mounting hole 2a.

  On the other hand, the inner peripheral surface (convex surface on the inner space 3b side) 3u of the recessed portion 3k is in contact with the leg portion 4b (particularly the clamping portion 4d) of the cap 4 with the entire width L of the recessed portion 3k. Therefore, compared with the case where the hollow 3k is divided, the contact area to the leg 4b made of resin is increased, so that the deformation of the clamping portion 4d is suppressed and the rattling of the clip does not occur. Therefore, it is possible to prevent the clip 3 from coming out of the mounting hole 2a. Furthermore, since the bead 3r also serves as a reinforcing rib of the elastic locking portion 3a, the rigidity of the clip 3 itself can be increased.

  In the present embodiment, the escape portion is the bead 3r protruding toward the internal space 3b, but a long hole may be formed in a portion corresponding to the bead 3r. By replacing the bead 3r with a long hole, the rigidity of the clip is lowered, the clip insertion load is reduced, and the mounting workability of the parts can be improved.

  In the present embodiment, the clip 3 is inserted into the mounting hole 2 a of the vehicle side panel 2 after the leg portion 4 b of the cap 4 is inserted into the internal space 3 b of the clip 3. This is because the base 11, the grip body 10, the clip 3 and the cap 4 of the assist grip 1 are integrated as an integrated product to facilitate transportation and handling. However, even if this order is reversed, the effect of the present invention can be exhibited. That is, first, the clip 3 is inserted into the mounting hole 2a without inserting the leg 4b of the cap 4 into the internal space 3b of the clip 3, and then the leg 4b of the cap 4 is inserted into the internal space 3b of the clip 3. You may do it. In this case, the leg 4b of the cap 4 can be completely inserted into the internal space 3b of the clip 3 with one action.

  In this embodiment, the assist grip, which is one of the vehicle interior parts, is applied as a part, but it is also applied to parts inside and outside the vehicle such as a console box, an instrument panel, a sun visor, a coat hook, a register, and a room lamp. it can.

  Further, in this embodiment, the part holding the clip is composed of two members, the grip body 10 and the base 11, but if the base has the structure of the present invention, one member The parts may be constituted by Of course, the component may be composed of a base and other two or more members.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention described in the claims. Of course there is.
