Abstract
A roof ditch molding having a Class A finish seamlessly including the end caps thereof. An extruded central molding member includes a beam and a head, wherein the end sections have the beam removed and the head is contoured and provided with a notch. The end sections are then placed into a plastic injection molding machine whereat the head is folded at the notch a shot of plastic deposited adjacent the notch for retention of the fold angle and stiffening of the now formed end caps. A pair of nibs provide engagement with spring clips at the ends of the roof ditch.
Claims11
A roof ditch molding for a roof ditch of a motor vehicle, comprising:
- a main molding member comprising a head and an integrally formed beam;
- and
- at least one end cap integrally formed of said head;
- wherein said head has at least one fold notch formed therein, said at least one fold notch being disposed transversely across said head;
- wherein each end cap comprises a transverse bend in said head, wherein the bend is superposed a respective fold notch;
- and
- wherein a plastic brace secures each end cap, respectively, to said beam adjacent its respective fold notch.
A method for making a roof ditch molding, comprising the steps of:
- extruding a central molding member comprising a head and an integral beam;
- removing the beam from at least one end of said central molding member;
- forming a fold notch in the head at the at least one end;
- bending said head superposed a respective fold notch in the head at the at least one end to provide an end cap thereat, wherein the end cap formed at the at least one end is integrally formed of said head;
- and
- injection molding a plastic brace onto said central molding member adjacent said fold notch, wherein said brace retains said end cap at a predetermined angle with respect to said head.
A roof ditch molding and roof ditch of a motor vehicle, comprising:
- a roof ditch comprising:
- overlapped panel edges mutually forming a slot;
- and
- a spring clip located adjacent each end of said slot;
- and
- an end formed roof ditch molding fitted into said roof ditch, said end formed roof ditch molding comprising:
- a main molding member comprising a head and an integrally formed beam;
- at least one end cap integrally formed of said head;
- a pair of nibs formed on said beam, one nib being respectively disposed at each side of said beam;
- and
- wings connected with a lower extremity of said beam, wherein said pair of nibs are located on said beam between said head and said wings;
- wherein said wings are present only at discrete, mutually spaced locations along said beam, wherein said wings are absent at a portion of each end of said main molding member;
- and wherein at the portion of each end whereat said wings are absent, said nibs are located at the substantially lowermost extremity of said beam;
- wherein said pair of nibs are interferingly engaged with the spring clips so as to thereby retain said end formed roof ditch molding in said roof ditch;
- wherein said head has at least one fold notch formed therein, said at least one fold notch being disposed transversely across said head;
- wherein each end cap comprises a transverse bend in said head, wherein the bend is superposed a respective fold notch;
- and
- wherein a plastic brace secures each end cap, respectively, to said beam adjacent its respective fold notch.
