Modes for Carrying Out the Invention

[0008] [First Embodiment] With reference to FIGS. 1 to 6, the mounting structure according to the first embodiment of the present disclosure will be described. FIG. 1 shows a lower mold 90 which is a vehicle part. The lower mold 90 is, for example, a molded resin product, has an elongated shape extending in the longitudinal direction of the vehicle 91, and the outer surface is a design surface. Further, a plurality of clip mounting portions 10 are integrally formed at a plurality of locations along the longitudinal direction on the inner surface of the lower mold 90. Then, the lower mold 90 is fixed to the lower edge portions of both side surfaces of the vehicle body by clips 50 held by the plurality of clip mounting portions 10. In the present embodiment, the mounting structure according to the present disclosure is applied to the clip mounting portion 10, and the support target member in the clip mounting portion 10 is the clip 50.

[0009] FIG. 6A shows the entire clip 50. The clip 50 is, for example, a molded resin product, includes a disc spring portion 53 and a head portion 54 at one end of a bobbin portion 55, and has a substantially axisymmetric shape as a whole. The bobbin portion 55 has a structure in which a pair of flange portions 52 project laterally from both ends of a cylindrical portion 51. The disc spring portion 53 has a circular thin disc shape, the central portion is connected to the central portion of the outer surface of one flange portion 52, and the portion other than the central portion floats from the outer surface of the flange portion 52. The head portion 54 projects from the central portion of the disc spring portion 53, has a teardrop-shaped longitudinal cross-sectional shape, and has a maximum outer diameter portion at an intermediate position.

[0010] FIG. 2 shows the entire clip mounting portion 10. The clip mounting portion 10 has, for example, a substantially box shape with an open side surface, and includes three side walls 11A, 11B, 11C protruding from the inner surface of the lower mold 90 and a support wall 12 supported by them and facing the inner surface of the lower mold 90. Of the three side walls 11A, 11B, 11C, a pair of side walls 11A, 11B are parallel to each other and face each other, and the remaining side wall 11C is orthogonal to the pair of side walls 11A, 11B and connects the pair of side walls 11A, 11B. Further, one of the pair of opposing side walls 11A, 11B, i.e., the side wall 11A, is wider in width than the other side wall 11B. Hereinafter, when distinguishing between the side walls 11A, 11B, 11C, they will be referred to as "first side wall 11A", "second side wall 11B", and "third side wall 11C".

[0011] The support wall 12 is formed with a locking hole 13 and an introduction groove 14. The locking hole 13 is a hole for locking the clip 50 and penetrates the support wall 12. The locking hole 13 is located, for example, closer to the third side wall 11C of the support wall 12 and has a semi-circular shape that bulges toward the third side wall 11C side. Also, the radius of the semi-circle of the locking hole 13 is substantially the same as the radius of the cylindrical portion 51 (see FIG. 6A) of the clip 50, for example.

[0012] The introduction groove 14 has an opening 14K at the end of the support wall 12 on the side opposite to the third side wall 11C and is connected to the locking hole 13 from the side. Also, due to the opening 14K, the end face of the support wall 12 on the side opposite to the third side wall 11C is divided into a first end face 12A on the first side wall 11A side and a second end face 12B on the second side wall 11B side. The first end face 12A is flush with the end face of the first side wall 11A on the side opposite to the third side wall 11C, while the second end face 12B is flush with the end face of the second side wall 11B on the side opposite to the third side wall 11C. And the first end face 12A is located on the side farther from the locking hole 13 than the second end face 12B. Note that the lateral widths of the pair of opposing side walls 11A and 11B are equal, and the first end face 12A and the second end face 12B may be flush on the side away from the locking hole 13.

[0013] Hereinafter, as shown in FIG. 3, a line that bisects the semi-circle in the planar shape of the locking hole 13 is defined as the center line L1, the side of the inner surface of the introduction groove 14 on the first side wall 11A side from the center line L1 is defined as the first groove side surface 15, and the side of the second side wall 11B side from the center line L1 is defined as the second groove side surface 16. The second groove side surface 16 includes a straight line portion 16A that extends parallel to the center line L1 from one end of the semi-circle that is the planar shape of the locking hole 13, and a straight line portion 16B that connects between the straight line portion 16A and the second end face 12B and inclines away from the center line L1 as it moves away from the locking hole 13. That is, the second groove side surface 16 is not provided with an overhanging portion that overhangs toward the first groove side surface 15 side from one end of the semi-circle that is the planar shape of the locking hole 13.

[0014] On the other hand, the first groove side surface 15 includes a curved portion 15A that crosses the other end of the semicircle that is the planar shape of the locking hole 13 obliquely and bulges toward the third side wall 11C, and a straight portion 15B that is parallel to the center line L1 and extends toward the first end face 12A from a position of the curved portion 15A away from the locking hole 13. Note that the curved portion 15A may bulge toward the side opposite the third side wall 11C, or may extend so as to cross the other end of the semicircle that is the planar shape of the locking hole 13 at a right angle.

[0015] A retaining piece 20 extends in a cantilever shape toward the locking hole 13 from an end of the straight portion 15B of the first groove side surface 15 away from the locking hole 13. The entire retaining piece 20 extends toward the center line L1 substantially perpendicular to the straight portion 15B and then bends toward the locking hole 13, and extends closer to the center line L1 as it approaches the locking hole 13, and has a head portion 21 at its tip.

[0016] The head portion 21 is wider than the position near the tip of the retaining piece 20, and the retaining surface 21K of the head portion 21 facing the retaining hole 13 has an arc shape that approximately coincides with an imaginary circle C1 that is an extension of the semicircular inner surface 13A of the retaining hole 13. The arc length of the retaining surface 21K is, for example, about 1 / 12 to 2 / 12 of the circumference of the imaginary circle C1. Furthermore, one end of the retaining surface 21K is located, for example, near the center line L1. Note that one end of the retaining surface 21K may intersect with the center line L1.

[0017] Among the side parts of the retaining piece 20, the inner part 22 facing inward (toward the center line L1) includes a straight part 22B that extends from the first end face 12A toward the locking hole 13 so as to approach the second groove side surface 16, and a straight part 22A that extends slightly in parallel to the center line L1 from the end of the straight part 22B to the head part 21. One end part in the width direction of the head part 21 is a bulging part 21B that bulges in an arc shape from the straight part 22A toward the center line L1.

[0018] On the outer portion 23 of the side portion of the retaining piece 20 that faces the outside (opposite to the center line L1), a plurality of notches 23A, 23B, 23C are formed from the base end portion of the retaining piece 20 to a position closer to the tip. These notches 23A, 23B, 23C are arranged adjacent to each other in a substantially semi-circular shape. More specifically, the notch 23C located on the base end side of the retaining piece 20 is larger than the other notches 23A, 23B and is curved so as to bulge toward the first end face 12A. The notch 23B in the middle portion of the retaining piece 20 is curved so as to bulge toward the straight portion 22B of the inner portion 22 of the retaining piece 20. The notch 23A closer to the tip of the retaining piece 20 is curved so as to bulge toward the straight portion 22A of the inner portion 22 of the retaining piece 20. And, in the retaining piece 20, the portions with reduced width due to the notches 23A, 23B, 23C have become the first joint portion 24A, the second joint portion 24B, and the third joint portion 24C. In other words, the first joint portion 24A is arranged at a position protruding from the first groove side surface 15 in the retaining piece 20 more than the second joint portion 24B, and the second joint portion 24B is arranged at a position protruding from the first groove side surface 15 in the retaining piece 20 more than the third joint portion 24C. Also, the second joint portion 24B is wider and has higher rigidity than the first joint portion 24A, and the third joint portion 24C is wider and has higher rigidity than the second joint portion 24B. Note that the widths of the first joint portion 24A and the second joint portion 24B may be the same, and the rigidities of the first joint portion 24A and the second joint portion 24B may be the same. Also, in the following description, when the first joint portion 24A, the second joint portion 24B, and the third joint portion 24C are not distinguished, they are collectively referred to as "joint portions 24A, 24B, 24C".

[0019] The description of the structure of the clip attachment portion 10 is as above. The clip 50 (see FIG. 6A) is attached to the clip attachment portion 10 as follows. That is, the clip 50 has its cylindrical portion 51 facing the introduction groove 14 of the clip attachment portion 10 from the side, and a pair of flange portions 52 are pushed into the locking hole 13 at the back of the introduction groove 14 so as to be positioned above and below the support wall 12 of the clip attachment portion 10. Then, as shown in FIG. 4A, the cylindrical portion 51 of the clip 50 abuts against the straight portion 16B of the second groove side surface 16 of the introduction groove 14 and the straight portion 22B of the inner portion 22 of the retaining piece 20. When the clip 50 is further pushed in, as shown in FIG. 4B, the retaining piece 20 receives the pressing force from the clip 50 at the straight portion 22B, and the second joint portion 24B is bent and deformed, and although slightly, the third joint portion 24C is also bent and deformed. At this time, since the first joint portion 24A does not receive the bending force, it is not bent and deformed. Then, when the clip 50 is further pushed in, as shown in FIG. 5A, the cylindrical portion 51 of the clip 50 abuts against the tip side (specifically, the bulging portion 21B of the head portion 21) of the retaining piece 20 from the boundary portion between the straight portions 22A and 22B, and the first joint portion 24A is bent and deformed. At this time, due to the bending deformation of the first joint portion 24A, the bending force on the second joint portion 24B and the third joint portion 24C decreases, and the bending deformation of the second joint portion 24B and the third joint portion 24C slightly returns. Then, when the clip 50 is further pushed in, the bending deformation of all the joint portions 24A, 24B, and 24C progresses. When the cylindrical portion 51 of the clip 50 passes through the head portion 21 of the retaining piece 20, as shown in FIG. 5B, all the joint portions 24A, 24B, and 24C elastically return, and the locking surface 21K of the head portion 21 opposes the side surface of the cylindrical portion 51 of the clip 50 to prevent the clip 50 from coming off, and the attachment of the clip 50 to the clip attachment portion 10 is completed (see FIG. 6B).

[0020] When clips 50 are attached to all the clip attachment parts 10 of the lower mold 90, the head parts 54 of the respective clips 50 are pushed into through holes (not shown) formed through the wall part (not shown) of the vehicle body of the vehicle 91. Specifically, the head part 54 is pushed into the through hole until the maximum outer diameter part of the head part 54 reaches a position passing through the through hole in the wall part of the vehicle body. Then, the disc spring part 53 is in a state of elastic deformation, and the opening edge of the through hole in the wall part of the vehicle body is sandwiched between the disc spring part 53 and the maximum outer diameter part of the head part 54. Thus, the lower mold 90 is fixed to the vehicle body.

[0021] According to the configuration of the clip attachment part 10 of the above-described present embodiment, the following operational effects are achieved. The retaining piece 20 of the clip attachment part 10 of the present embodiment has a novel structure in which a plurality of joint parts 24A, 24B, 24C are arranged in the longitudinal direction. And those plurality of joint parts 24A, 24B, 24C are concave, and the retaining piece 20 is narrowed by the plurality of joint parts 24A, 24B, 24C. Therefore, when the retaining piece 20 is pushed by the clip 50, it bends locally at a plurality of locations. As a result, the entire retaining piece 20 is easily bent into a curved shape, the resistance by the retaining piece 20 when pushing the clip 50 toward the locking hole 13 is suppressed, and the attachment work of the clip 50 can be easily performed.

[0022] Further, the second joint part 24B is arranged at a position protruding from the first groove side surface 15 of the retaining piece 20 more than the third joint part 24C. And since the third joint part 24C is wider and has higher rigidity than the second joint part 24B, when the retaining piece 20 is pushed by the clip 50, after the second joint part 24B bends greatly, the third joint part 24C bends greatly. As a result, the entire retaining piece 20 bends into a well-balanced curved shape. In the present embodiment, the first joint part according to the present disclosure is applied to the second joint part 24B, and the second joint part according to the present disclosure is applied to the third joint part 24C.

[0023] Furthermore, during the process of attaching the clip 50, the second joint portion 24B and the third joint portion 24C on the proximal side of the first joint portion 24A at the distal end side of the retaining piece 20 are first bent and deformed, and then, when the first joint portion 24A is bent and deformed, the second joint portion 24B and the third joint portion 24C are operated so that the bending deformation slightly returns. Further, thereafter, all the joint portions 24A, 24B, 24C are deformed so that the bending deformation progresses and then elastically returns, and the attachment of the clip 50 is completed. However, when the retaining piece 20 is pressed by the clip 50 after the attachment is completed, a bending force is applied to all of the joint portions 24A, 24B, 24C. Therefore, the pressing force from the clip 50 does not perform the reverse operation of the above-described clip 50 attachment process, and the clip 50 does not come off from the clip attachment portion 10.

[0024] Also, in the clip attachment portion 10 of the present embodiment, since the uneven portion including the concave portion formed by the joint portions 24A, 24B, 24C is formed on the outer portion 23 of the retaining piece 20, the clip 50 smoothly slides on the inner portion 22 of the retaining piece 20. Also in this regard, the attachment work of the clip 50 can be easily performed. Furthermore, since the second groove side surface 16 on the side opposite to the first groove side surface 15 having the retaining piece 20 in the introduction groove 14 does not have an overhanging portion, when the clip 50 is pushed into the locking hole 13, the clip 50 can be smoothly pushed in by guiding the clip 50 along the first groove side surface 15 of the introduction groove 14.

[0025] [Second Embodiment] The clip attachment portion 10V of the present embodiment is shown in FIG. 7. In the first embodiment, the number of the joint portions 24A, 24B, and 24C of the retaining piece 20 was three, whereas the retaining piece 20V of the present embodiment includes two joint portions 24D and 24E excluding the third joint portion 24C. Further, in the clip attachment portion 10 of the first embodiment, the cutouts 23A, 23B, and 23C for forming the joint portions 24A, 24B, and 24C in the retaining piece 20 opened to the outer portion 23 of the retaining piece 20. However, in the clip attachment portion 10V of the present embodiment, the cutouts 23D and 23E for forming the joint portions 24D and 24E open to the inner portion 22 side of the retaining piece 20V. Furthermore, the cutouts 23A, 23B, and 23C of the first embodiment are semi-circular, and the opening is wider than the inner portion. However, the cutouts 23D and 23E of the retaining piece 20 of the present embodiment have a shape obtained by cutting one part of a circle, and the opening is narrower than the inner portion. Since the configurations other than the above are the same as those of the first embodiment, the overlapping description is omitted.

[0026] The retaining piece 20V of the clip attachment part 10V in this embodiment also has a plurality of joint parts 24D and 24E in the longitudinal direction, similar to the retaining piece 20 in the first embodiment, and is locally bent at a plurality of positions. As a result, the entire retaining piece 20V can be easily bent into a curved shape, and the attachment operation of the clip 50 can be easily performed. Further, the notches 23D and 23E for forming the joint parts 24D and 24E open to the inner side part 22 side of the retaining piece 20V, but they are smaller than the cylindrical part 51 of the clip 50 and only open slightly in a slit shape. Therefore, the cylindrical part 51 of the clip 50 can be smoothly pushed into the locking hole 13 without being caught by the notches 23D and 23E. When a pressing force is applied to the retaining piece 20V from the clip 50 after the attachment is completed, although not shown, the opposing surfaces sandwiching the openings of the notches 23D and 23E approach or contact each other, and the rigidity of the retaining piece 20 increases. That is, according to the structure of the clip attachment part 10V in this embodiment, the rigidity of the retaining piece 20 for bending inside the introduction groove 14 is higher than the rigidity for bending outside the introduction groove 14. Thereby, the clip 50 can be easily attached and firmly prevented from coming off. Note that the shapes of the joint parts 24D and 24E and the notches 23D and 23E are not limited to the above, and as shown in FIG. 8, they may be narrow slit shapes.

[0027] [Other Embodiments] In the first and second embodiments, examples in which the retaining pieces 20 and 20V are provided with two or three joint parts are shown, but the number of joint parts may be one or any plurality. Further, in the retaining piece 20V of the second embodiment, even if the number of joint parts is one, the rigidity can be made different depending on the bending direction, and the effect that the clip 50 can be easily attached and firmly prevented from coming off can be obtained.

[0028] The retaining pieces 20 and 20V in the first and second embodiments include the head part 21 and the tip part is wide, but they may not include the head part 21 and may have a tapered shape.

[0029] In the first and second embodiments, the retaining piece 20 was provided only on one of the two groove side surfaces (the first groove side surface 15 and the second groove side surface 16) of the introduction groove 14, but the retaining piece 20 may be provided on both sides.

[0030] In the first and second embodiments, the clip 50 was shown as an example of the component to be supported, but the component to be supported is not limited to this. Also, the lower roll 90 was exemplified as a component having the clip attachment portions 10, 10V, but the clip attachment portion 10 may be provided on automotive parts other than the lower roll 90, or members other than automotive parts. For example, when the component to be supported is a pole, the same structure as the clip attachment portions 10, 10V of the first or second embodiment may be applied to a hook attached to the pole, or when the component to be supported is a harness, the same structure as the clip attachment portions 10, 10V of the first or second embodiment may be applied to a harness holder to which the harness is attached from the side.

[0031] In the above embodiment, the node portions 24A to 24E were formed by forming the notch portions 23A to 23E in the retaining piece 20, but the retaining piece may be provided with node portions that are easily bent locally without forming notch portions. For example, the width of the retaining piece may be substantially uniform, and node portions with locally reduced wall thickness may be provided at a plurality of locations in the longitudinal direction of the retaining piece. Also, the retaining piece may have a shape that is uniform in both width and wall thickness and is bent at a plurality of locations in the longitudinal direction, with the plurality of bent portions serving as the plurality of node portions. And when the retaining piece is pushed by the component to be supported, the bending force may be concentrated on the plurality of node portions so that the plurality of node portions are locally bent.

[0032] <Supplementary Note> Hereinafter, the feature groups extracted from the above embodiments will be described while showing effects and the like as necessary.

[0034] The retaining piece of the mounting structure of Feature 1 has a novel structure in which a plurality of joint portions are arranged in the longitudinal direction. And those plurality of joint portions are concave, and the retaining piece is narrowed at the plurality of joint portions, so when the retaining piece is pushed by the supported component, it bends locally at multiple locations. As a result, the whole of the retaining piece easily bends into a curved shape, the resistance by the retaining piece when pushing the supported component toward the locking hole is suppressed, and the mounting operation of the supported component can be easily performed.

[0035] [Feature 2] The plurality of joint portions (24A to 24E) include a first joint portion (24A, 24D) and a second joint portion (24B, 24E) located closer to the proximal end side of the retaining piece (20, 20V) than the first joint portion. The first joint portion (24A, 24D) protrudes from the side surface more than the second joint portion (24B, 24E), and the second joint portion (24B, 24E) has higher rigidity than the first joint portion (24A, 24D).

[0038] In the mounting structure of Feature 3, since the uneven portions including the concave portions formed by the node portions are formed on the outer portion of the retaining piece on the outside of the introduction groove, the component to be supported smoothly slides on the inner portion of the retaining piece, and the mounting operation of the component to be supported can be easily performed.

[0039] [Feature 4] The retaining piece (20V) has notch portions (23D, 23E) on the inner portion facing the inside of the introduction groove (14), the portion narrowed by the notch portions (23D, 23E) forms the node portions (24D, 24E), and a pair of opposing surfaces in the notch portions (23D, 23E) come into contact before the component to be supported (50) passes through the introduction groove (14), thereby retaining the component to be supported (50). The mounting structure according to any one of Features 1 to 3 above.

[0040] According to the structure of Feature 4, the retaining piece has higher rigidity to bend inward of the introduction groove than the rigidity to bend outward of the introduction groove. That is, according to this configuration, the component to be supported can be easily mounted and firmly retained.

[0041] [Feature 5] The retaining piece (20) is provided on one of the pair of side surfaces of the introduction groove (14), and on the other side surface of the introduction groove (14), there is no protruding portion that protrudes to the one side surface side of the other side surface side of the locking hole (13) in the width direction of the introduction groove (14).
