Description

FIELD

[0001] The present disclosure relates to clips for coupling a molding to a ditch in the surface of a motor vehicle, and more particularly to clips for coupling a cover over a roof ditch of an automobile.

BACKGROUND

[0002] This section provides background information related to the present disclosure which is not necessarily prior art.

[0003] It is common to use ditch moldings on motor vehicles. Ditch moldings may be applied in relation to surface ditches to cover joints, seams and other unappealing features, or they may be applied in relation to surface ditches simply for aesthetic purposes. Because it is not always easy to attach molding directly to automobile body parts, molding is often attached using a specialized retainer clip.

[0004] A variety of automobiles now include a roof ditch that extends along a portion of the roof above the doors. The roof ditch is typically defined by the joint between the roof and the side panel of the automobile. Typically, the roof ditch is covered at least in part by a roof ditch molding or cover. Such molding typically has an interior support of metal or the like with a generally "C" shaped section profile. The interior support can be covered with a more pliable material such as rubber or the like which extends outwardly to engage sides of the roof ditch.

[0005] In many applications, retaining clips couple the roof ditch cover to corresponding weld studs positioned along the roof ditch. In some instances, the lateral position of the various weld studs relative to the side or sides of the ditch can vary along the roof ditch. Since the clip operates by coupling to both the ditch cover and the stud, such variation in the lateral positioning of the weld studs can cause the cover to engage the side of the roof ditch, which can prevent the retaining clip from being able to operatively couple with both the cover and weld stud. Even if coupling is not prevented, the overlying molding will tend to be out of position, which can result in functional or aesthetic deficiencies of the ditch cover. Accordingly, a continuing need exists for a roof ditch molding retainer which accommodates lateral variations in the positioning of the weld studs along the length of the ditch molding.

SUMMARY

[0006] This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

[0007] In accordance with one aspect of the present disclosure, a ditch molding clip for coupling a molding to a weld stud of a ditch of a motor vehicle surface is provided. The ditch molding clip can include a single piece body. The single piece body can include (1) an outer frame surrounding an interior opening, (2) a clip-to-molding retention coupling including a plurality of resilient arm members extending from the outer frame and designed to engage and retain a corresponding edge of the molding, (3) a clip-to-weld-stud retention coupling positioned within the interior opening and including an aperture designed to receive and retain the weld stud, and (4) an extensible member extending between the outer frame and the clip-to-molding retention coupling. A longitudinal length of the extensible member can be designed to lengthen to allow the clip-to-weld stud retention coupling to move within the interior opening to accommodate for variations in the positioning of the weld stud relative to the ditch.

[0008] In accordance with one aspect of the present disclosure, a ditch cover clip for coupling a ditch cover to a weld stud of a ditch of a motor vehicle surface is provided. The ditch cover clip can include a single piece molded polymeric body. The single piece molded polymeric body can include (1) an outer frame surrounding an interior opening, (2) a clip-to-cover retention coupling including a plurality of resilient arm members extending from the outer frame and designed to engage and retain a corresponding edge of the cover, (3) a clip-to-weld-stud retention coupling positioned within the interior opening and including an aperture designed to receive and retain the weld stud, and (4) a pair of extensible members extending between the outer frame and the clip-to-cover retention coupling.

DETAILED DESCRIPTION

[0018] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0019] FIGS. 1-6 illustrate one example embodiment of a clip 20 in accordance with the present disclosure. The ditch molding or cover clip 20 is designed to couple a ditch molding or cover 11 to a weld stud 13 of a ditch 15 of a motor vehicle surface 17. The ditch 15 can include a pair of longitudinally extending side surfaces or side walls 19. Alternatively, the clip can be designed to couple a molding to the weld stud 13 of a ditch 15 of a motor vehicle surface 17 having a single side wall 19.

[0020] The ditch cover clip 20 can be a single-piece body 22 and can be a molded polymeric body 22. The body 22 can include an outer frame 24 surrounding an interior opening 26. A clip-to-molding or clip-to-cover retention coupling 28 can include a plurality of resilient arm members 30 extending laterally outwardly from the outer frame 24. The resilient arm members 30 can include coupling lips or detents 32 so that each resilient arm 30, including the coupling detent 32, is designed to engage and retain a corresponding edge 21 of the cover 11.

[0021] Outwardly extending stop members 36 can be provided to sandwich the corresponding edge between the detent 32 and the stops 36. Resilient arm members 34 can also be provided to engage a notch (not shown) in the edge 21 to prevent longitudinal movement of the clip 20 along the length of the cover 11. Alternatively, the resilient arm members 30 themselves can engage the edge 21 at such a notch.

[0022] A clip-to-weld-stud retention coupling 38 can be positioned within the interior opening 26. The clip-to-weld-stud retention coupling 38 can include an aperture 40 designed to receive and retain a head 23 of the weld stud 13. For example, the clip-to-weld-stud retention coupling 38 can include an angled entry surface 42 and an oppositely disposed retention surface 44. The aperture 40 can have an elongated oval shape to accommodate variations in the positioning of the weld stud 13. As in the illustrated example, the aperture 40 can be elongated in a direction that is aligned with the longitudinal direction of the ditch 15. Thus, the elongated oval aperture 40 can accommodate variations in the longitudinal positioning of the weld stud 13 relative to the ditch 15. Alternatively, the aperture 40 can be elongated in a direction that is transverse to the longitudinal direction of the ditch 15 to accommodate variations in the lateral positioning of the weld stud 15 relative to the ditch 15.

[0023] A pair of extensible members 46 can extend between the outer frame 24 and the clip-to-molding retention coupling 38. The extensible members 46 are designed to lengthen longitudinally to allow the clip-to-weld stud retention coupling 38 to move within the interior opening 26 to accommodate for variations in the positioning of the weld stud 13 relative to the ditch 15. In the illustrated example, the extensible members 46 have a corrugated configuration in which corrugations of the corrugated wall extend in a side-to-side direction that is transverse to the longitudinal direction of the extensible members. In other words, the sinusoidal end wall 48 of the corrugated wall 50 faces toward the top of the clip 22.

[0024] As in the illustrated embodiment, the corrugated extensible members 46 can have non-extended position extending, or can be molded to, or can initially, extend in a direction in which the longitudinal lengthening of the extensible members 46 accommodates variations in the lateral positioning of the weld stud 13 relative to the ditch 15. Alternatively, the corrugated extensible members 46 can have a non-extended or initial position extending in a direction in which longitudinal lengthening of the extensible members 46 accommodates variations in the longitudinal positioning of the weld stud 13 relative to the ditch 15.

[0025] As in the illustrated example, in the non-extended or initial position of the extensible members 46, the extensible members 46 can longitudinally extend in a direction that is in alignment with the direction in which the aperture 40 is elongated. In addition, this aligned direction that the extensible members 46 initially extend in, and that the aperture 40 is elongated in, can also be aligned with the longitudinal direction 54 of the ditch 15 and of the cover 11. Alternatively, this aligned direction that the extensible members 46 initially extend in, and that the aperture 40 is elongated in, can be aligned transverse to the longitudinal direction of the ditch 15.

[0026] The corrugated extensible members 46 can be designed to resist movement other than longitudinal lengthening thereof. For example, the extensible members 46 can be designed to resist torsional rotation about the longitudinal length 56 of the extensible member 46, of to resist rotation along the longitudinal length of the extensible members that would result in movement in a height direction, or both. As in the illustrated example, this can be accomplished in whole or in part, by the extensible member 46 having a height in a top-to-bottom direction (as oriented in FIG. 2) of the extensible member 46 that is substantially the same as the overall height of the outer frame 24.

[0027] This can also be accomplished in whole or in part, via the upper or top surface 48 of each extensible member 46. As in the illustrated example, the top surface 48 of each extensible member 46 is positioned adjacent an interior surface 25 of the ditch molding or cover 11 such that the top surface 48 of the extensible member 46 contact against the interior surface 25 of the ditch cover 11. This can also be accomplished in whole or in part, via the top surface 48 having an overall contact area width 58, due to its sinusoidal shape as a result of the corrugated configuration of the extensible member 46, that is greater than the largest transverse width 60 of the wall or member 50 per se that forms or is the extensible member 46. The transverse width 60 of the wall 50 per se can vary along its length in order to facilitate flexing and extension and contraction of the extensible member 46.

[0028] Use of the example clip illustrated herein can include coupling a plurality of the clips 20 to the ditch cover 11 at various positions along the longitudinal length thereof that correspond to various positions along the longitudinal length of the ditch 15 at which corresponding weld studs 13 have been attached. The clip-to-cover retention couplings 28 of each clip 20 engage and retain the opposing edges 21 of the cover 11 as described above. The resilient arm members 34 can facilitate correct longitudinal positioning of the clips 20 via engagement with notches in the edges 21 as described above.

[0029] This cover 11 and multi-clip 20 sub-assembly can then be positioned over the ditch 15 and pressed down to engage the clip-to-weld-stud coupling 38 of each clip against the head 23 of a corresponding weld stud 13. The elongated oval shape of the stud retaining aperture 40 can accommodate for variations in the longitudinal positioning of a weld stud 13 in the ditch 15.

[0030] Variations in the lateral positioning of a weld stud 13 in the ditch 15 can be accommodated for by the corrugated extensible members 46. For example, as the head 23 of a slightly laterally offset weld stud 13 engages the entry surface of the stud retaining aperture 40 and enters the aperture 40, the weld stud 13 becomes laterally centered within the aperture 40. To the extent the cover 11 and clip 20 are unable to move laterally to accommodate the lateral offset, a tensile force is exerted along the corrugated extensible members 46 causing them to elongate or increase their longitudinal length.

[0031] In some cases, the cover 11 and clip 20 is unable to move laterally as a result of lateral positioning forces imposed by clips 20 that have been previously coupled to weld studs 13 along the length of the cover 11. In some cases, the cover 11 and clip 20 is unable to move laterally as a result of lateral positioning forces imposed by the cover 11 engaging against an adjacent side edge or wall 19 of the ditch 15. In some cases, a combination of both these lateral positioning forces can be at play.

[0032] In the illustrated example, the initial, non-extended position (FIG. 4), the corrugated extensible members 46 extend longitudinally in an initial, non-extended direction 56 that is in alignment with the longitudinal direction 54 of the cover 11, the ditch 15, or both. In the extended position (FIG. 5), the corrugated extensible members 46 extend longitudinally in an extended direction 62 at an angle 64 to the non-extended direction 56 and to the longitudinal direction 54 of the cover 11 or ditch 15.
