DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

Referring generally to FIGS. 1-4, a vehicle door structure 1 is provided, the vehicle door structure 1 comprises a door panel 10 configured to couple to a vehicle frame (not shown). As used herein, the door panel 10 refers to outer sheeting or skin of a vehicle door, for example, the outer sheet metal of the vehicle door. At a lower portion 12 of the door panel 10, the door panel 10 may be coupled to a molding component 20. The lower portion 12 of the door panel 10 and the molding component 20 may be coupled via various mechanisms known to one of ordinary skill in the art. In one exemplary embodiment as shown in FIG. 4, the molding component 20 may comprise at least one clip 24, and the lower portion 12 of the door panel 10 may comprise at least one clip receptacle 14. For coupling, the at least one clip 24 is inserted into the least one clip receptacle 14 of the lower portion 12 until the molding component 20 is flush mounted against the lower portion 12 of the door panel 10. For increased retention of the molding component 20 to the door panel 10, a plurality of clips and clip receptacles may be used.
As used herein, “flush mounting” defines the coupling arrangement between the lower portion 12 of the door panel 10 and the molding component 20, wherein the molding component 20 is dimensioned such that a substantial portion of the interior surface is in contact with the outer surface of the lower door portion 12. In essence, the dimensions and shapes of the interior surface of the molding component 20 are configured to substantially match the dimensions and shapes of the outer surface of the lower portion 12 of the door panel 10, in some embodiments. Accordingly, in some embodiments, a cross-section taken along at least one section of door 12 and molding 20 would reveal complete contact and no gap between the two, such that road debris and moisture is prevented from contacting the door panel 10. By flush mounting using clips 14, the vehicle door structure 1 has a durable coupling mechanism between the door panel 10 and molding component 20, while maintaining the aesthetic appeal of the shapes and styling of the vehicle door structure 1. Such clips 14 can be placed integrally or separately along the interior of the molding component so that the fastener, e.g. clip is not visible from outside the vehicle. The vehicle door may have a corresponding structure to engage the clip on the molding 20. As shown in FIG. 4 the clip can comprise engaging male and female structures, one of each provided on the molding 20 and door portion 12 to hold the molding in place. Because the clip on the interior of the molding, no attachment mechanisms are visible from the extension. To further ensure the aesthetic appeal, the molding component 20 may, in a further embodiment, comprise a color which matches the color of the door panel 10.
In further embodiments, the lower portion 12 of the door panel 10 may comprise clip receptacles 14 disposed at multiple locations along the lower portion 12 of the door panel 10. Furthermore, it is contemplated to use more clips and/or receptacles than are necessary for coupling the molding 20 to the door panel 10, such that the molding 20 can be moved to a number of different spots along the door panel 10. This facilitates flush mounting of the molding component 20 at multiple locations along the lower portion 12 of the door panel 10. Conversely, the molding component 20 may also comprise clips 24 disposed at multiple locations along the molding component 20 to facilitate flush mounting of the molding component 20 at multiple locations along the lower portion 12 of the door panel 10. In other embodiments, the clip receptacles 14 may be stamped through or drilled into the outer sheet metal of the door panel 10.
In the exemplary embodiment of FIG. 3, the molding component 20 may comprise a lower lip 22 extending under the door panel 10. This lower lip 22 substantially prevents and/or blocks debris from contacting and possibly damaging the door panel 10. As defined herein, “debris” refers to any object, for example, road objects such as rocks and stones, which may cause chipping on the surface of the door panel 10. The molding component 20, due in part to the lower lip 22, is beneficial because it may block debris without the use of a rocker molding or another debris blocking component known to one of ordinary skill in the art.
The molding component 20 may comprise various materials known to one of ordinary skill in the art. For example, the molding component 20 may comprise a rigid material, such as a plastic or rigid polymeric material. To produce the desired shapes and dimensions of the molding component 20, the plastic material may be produced via extrusion, injection molding, or other processes known to one of ordinary skill in the art. In a further exemplary embodiment, the molding component 20 may comprise a coating overlaying the plastic. The coating may comprise a paint material, wherein the paint material composition is composed of protective materials.
