  Therefore, the conventional metal clip has an advantage that even if there is some variation in the plate thickness of the vehicle body panel, the variation can be effectively absorbed by the inclined shoulder of the locking leg. In particular, when a galling load is applied from the direction perpendicular to the direction in which the inclined shoulder of each locking leg is locked, the inclined shoulder of each locking leg is bent Since the hole edge of the mounting hole slightly slips on the inclined shoulder, this may cause unnecessary rattling.

  The present invention was developed in order to effectively solve the problems of the conventional metal clip, and the invention according to claim 1 includes a substrate having a fixing portion for fixing an automobile interior material, A pair of support legs extending from both side edges toward the mounting hole direction of the vehicle body panel, and two pairs of locking legs folded back from the tip portion toward the board on both sides of each support leg, The locking leg is a metal clip having an inclined shoulder that is locked to the edge of the mounting hole of the vehicle body panel, and the inclined shoulder is adjacent to the inclined shoulder on the plate end surface of the two pairs of locking legs. Protrusions projecting in a direction perpendicular to the projecting direction are provided.

  According to a second aspect of the present invention, on the premise of the first aspect, the upper end of each locking leg forms a free end, and a gap in the width direction exists between the supporting leg.

  According to a third aspect of the present invention, on the premise of the first or second aspect, the inclined shoulder of each locking leg is always in contact with the hole edge of the mounting hole of the vehicle body panel, and the protrusion of each locking leg is The panel mounting holes are opposed to each other with a small gap therebetween.

  According to a fourth aspect of the invention, on the premise of the first to third aspects, the protrusion of each locking leg is located on the side of the inclined shoulder and is inclined in the same direction as the inclined shoulder. To do.

  Therefore, in the invention described in claim 1, projections projecting in the direction perpendicular to the projecting direction of the inclined shoulders are provided on the plate thickness end surfaces of the two pairs of locking legs in proximity to the inclined shoulders. In relation to this, the load from the direction in which the inclined shoulder is locked corresponds to the locking of each inclined shoulder with respect to the hole edge of the mounting hole of the body panel, and conversely, from the direction orthogonal to this The galling load can be dealt with by the contact of each projection with the hole edge of the mounting hole of the vehicle body panel, so that the galling load from all directions is strengthened and there is no possibility of causing unnecessary rattling.

  In the invention according to claim 2, the projections are inserted into the mounting holes of the vehicle body panel in such a relationship that the upper ends of the respective locking legs are free ends and there is a gap between them. When moving over the hole edge, each locking leg uses a gap to bend and escape in the direction opposite to the protrusion, so when inserting the support leg and locking leg into the mounting hole of the body panel, the protrusion Will not get in the way.

  In the invention according to claim 3, the inclined shoulder of each locking leg is always in contact with the hole edge of the mounting hole of the vehicle body panel, and the protrusion of each locking leg is smaller than the hole edge of the mounting hole of the vehicle body panel. When the support leg and the locking leg are inserted into the mounting hole of the vehicle body panel and the inclined shoulder of the locking leg is locked to the hole edge of the mounting hole, the locking leg is locked. The protrusions of the mounting holes are always over the hole edge of the mounting hole, preventing the occurrence of assembly failure. Prevent it from happening.

In the invention according to claim 4, the protrusion of each locking leg is located on the side of the inclined shoulder and is inclined in the same direction as the inclined shoulder. The hole edge of the hole slightly slips, and once the outer edge of the protrusion comes into contact with the hole edge of the mounting hole, it is no longer possible to slip.
Unnecessary rattling can be prevented more effectively.

  In the present invention, the inclined shoulders are locked by providing protrusions protruding in the direction perpendicular to the protruding direction of the inclined shoulders on the plate thickness end surfaces of the two pairs of locking legs close to the inclined shoulders. Corresponding load from the direction is dealt with by locking each inclined shoulder to the hole edge of the mounting hole of the body panel. Correspondingly by the contact of each protrusion with the hole edge of the hole, it is strengthened against a galling load from all directions to effectively prevent the occurrence of unnecessary rattling.

  Hereinafter, if the present invention is described in detail based on a preferred embodiment illustrated, the metal clip according to the embodiment was also developed for the purpose of attaching an automobile interior material such as a garnish to a vehicle body panel. Is integrally formed by punching a thin metal plate in the same manner as the conventional one.

  As shown in FIGS. 1 to 4, the metal clip includes a board 1 having a screw receiving hole 2 as a fixing part for screwing an automobile interior material, and a mounting edge of a vehicle body panel from both side edges of the board 1. A pair of support legs 3 extending in a V-shape toward each other, and two pairs of locking legs 4 that are folded back upward and outward toward the substrate 1 on the opposite sides of the support legs 3 from both ends thereof, A short pair of rattle prevention pieces 5 extending in the same direction as the support legs 3 from both ends of the substrate 1 are provided.

  Specifically, the pair of support legs 3 extend continuously from the center of the opposite side edges of the substrate 1, but the portion 3a near the substrate 1 has an angle perpendicular to the vehicle body panel surface. It hangs down in a straight line, and the tip 3b side is configured to come into contact with a gradually narrowing distance.

  The two pairs of locking legs 4 are continuously extended so as to incline upward and outward from both side edges of the front end of each of the support legs 3. The inclined shoulder 6 that is bent and elastically locked to the hole edge of the mounting hole of the vehicle body panel is formed so as to protrude, and the protruding end of the inclined shoulder 6 is orthogonal to the plate thickness end surface on the side of each inclined shoulder 6. The projections 7 projecting in the direction to be provided are individually provided. Accordingly, on each of the opposing sides of the substrate 1, one support leg 3 is located in the center, and the two locking legs 4 are located on both sides of the support leg 3 with a gap 8 in the width direction interposed. It will be.

  In addition, since each said protrusion 7 will be inclined in the same direction as the said inclination shoulder 6 by the relationship located in the side of the corresponding inclination shoulder 6, when the twist load is added, the outer edge will become a vehicle body Although it will contact the edge of the mounting hole of the panel, when the support leg 3 and the locking leg 4 are inserted into the mounting hole of the vehicle body panel, the inclined shoulder 6 of the locking leg 4 is Although it always abuts against the edge of the mounting hole, the projection 7 of the locking leg 4 faces the mounting hole of the vehicle body panel with a small gap interposed therebetween.

  The pair of rattle prevention pieces 5 hang down at an angle perpendicular to the vehicle body panel surface from the center of the opposite end edges of the substrate 1 on which the support legs 3 are not extended. By cooperating with the shape part 3a and contacting the four sides of the mounting hole of the vehicle body panel, it helps to prevent the clip itself from rattling and at the same time prevents the support leg 3 and the locking leg 4 from being bent and deformed. It is what.

  Therefore, when the automobile interior material 11 is attached to the vehicle body panel 13 using the metal clip having such a configuration, first, the through hole 12 previously drilled in the automobile interior material 11 and the screw receiving hole of the metal clip. 2 is obtained, and when the tip of the tapping screw 15 is screwed into the screw receiving hole 2 while the tapping screw 15 is inserted from the through hole 12 of the automobile interior material 11, As shown in FIG. 5, the metal clip is attached to the automobile interior material 11 side.

  Therefore, if the support leg 3 and the locking leg 4 on the metal clip side are inserted into the mounting holes 14 formed in the vehicle body panel 13 in advance, with the above-mentioned pre-attached state, FIG. As shown in FIG. 2, the two pairs of locking legs 4 are bent inward and pass through the hole edge of the mounting hole 14 to elastically lock the respective inclined shoulders 6 to the hole edge of the mounting hole 14. The automobile interior material 11 is attached to the vehicle body panel 13 side with one touch.

  When inserting into the mounting hole 14, the upper end of each locking leg 4 forms a free end, and the projection 7 is connected to the vehicle body panel 13 because there is a gap 8 between the supporting leg 3. When each of the locking legs 4 is inserted into the mounting hole 14 and gets over the edge of the hole, the locking legs 4 bend in the direction opposite to the protrusions 7 by using the gaps 8 so as to escape. When the leg 4 is inserted into the mounting hole 14 of the vehicle body panel 13, the four protrusions 7 do not get in the way. In this state, each protrusion 7 faces the hole edge of the mounting hole 14 of the vehicle body panel 13 with a small gap interposed therebetween.

  Then, in the state in which the automobile interior material 11 is attached, as shown in FIG. 7, if a squeeze load P1 is applied from the direction in which the inclined shoulder 6 is locked, the attachment hole 14 of the vehicle body panel 13 is applied. The four inclined shoulders 6 are locked to the hole edges, and conversely, when a galling load P2 is applied from a direction orthogonal thereto, the hole edges of the mounting holes 14 of the vehicle body panel 13 face each other. Since it can respond by contact | abutting with respect to the hole edge of the four protrusions 7, it is strengthened with respect to the galling load P1 * P2 from all directions, and there is no possibility of producing unnecessary rattling.

  In particular, in the latter case, when a squeeze load P2 is applied, the hole edge of the inclined shoulder 6 and the mounting hole 14 slightly slips, and once the outer edge of the projection 7 contacts the hole edge of the mounting hole 14, Slip does not easily occur, and unnecessary rattling can be more effectively prevented.

  The metal clip according to the present invention is strengthened against galling load in all directions, and the metal clip itself can effectively prevent unnecessary rattling, so when attaching an automobile interior material such as garnish to a vehicle body panel, It will be convenient.
