Trim attachment method and associated product
View Patent ↗A decorative trim assembly and the process of manufacturing includes providing a clip, supplying an elongated metal bright strip, and inserting the clip inside the metal bright strip. Subsequently, bending the assembled bright strip with the clip along its longitudinal extent provides a final conformation of the structure. It is subsequently secured to a weatherstrip by snap-fit operation. The end customer maintains the ability to service the decorative trim piece independently of the weatherstrip system.
1. A process of manufacturing a decorative trim assembly that is subsequently attached to an associated weatherstrip comprising:
providing a clip;
supplying an elongated metal bright strip;
assembling at least a portion of the clip to the metal bright strip such that relative movement between the clip and bright strip is allowed in a longitudinal direction; and
bending the assembled bright strip with the clip along its longitudinal extent.
2. The process of claim 1 wherein the clip providing step includes extruding the clip upstream of the assembling step.
3. The process of claim 1 wherein the clip providing step includes supplying the clip from a previously manufactured inventory of continuous material.
4. The process of claim 3 wherein the inventory includes a roll and the supplying step includes the step of unrolling the clip from the roll.
5. The process of claim 1 wherein the bright strip supplying step includes forming the bright strip into a generally U-shaped cross-section to form a cavity.
6. The process of claim 5 wherein the assembling step includes introducing the clip into the bright strip cavity and subsequently deforming edges of the bright strip to mechanically retain the clip therein.
7. The process of claim 6 wherein the deforming step includes transforming the cross-section of the bright strip from the U-shaped cross-section into a C-shaped cross-section.
8. The process of claim 5 wherein the assembling step includes deforming an edge of the bright strip relative to the clip for mechanically joining the bright strip to the clip.
9. The process of claim 1 wherein the clip is a longitudinally continuous profile.
10. The process of claim 1 wherein the clip and bright strip have substantially equal longitudinal lengths.
11. The process of claim 1 further comprising securing the bent bright strip with clip on to an associated weatherstrip.
12. The process of claim 1 wherein the bright strip has a non-planar cross-sectional configuration and the process includes inserting the clip into the bright strip configuration.
13. The process of claim 1 wherein the assembling step includes inserting at least a portion of the clip inside the metal bright strip.
14. A product formed according to the process of claim 1 .
15. The process of claim 1 wherein the clip providing step includes configuring the clip to have a generally mushroom-shaped internal cavity that conforms to an associated protrusion on the associated weatherstrip.
16. The process of claim 1 wherein the clip providing step includes configuring the clip to have a connecting leg dimensioned for receipt in an associated groove of the associated weatherstrip.
17. The process of claim 16 wherein the clip providing step includes providing a barb portion on the connecting leg of the clip to aid in retaining the clip to the associated weatherstrip.
18. The process of claim 1 further comprising rough cutting the clip and metal bright strip to a desired length.
19. The process of claim 18 wherein the bending step includes stretch bending the assembled bright strip with the clip along its longitudinal length.
20. The process of claim 1 further comprising end forming at least one end of the clip and bright strip assembly to close-off the at least one end.
