Perimeter message and clearance lighting for cargo vehicle container body

Claim 2

In a highway cargo vehicle including at least one chassis-mounted container body adapted to be drawn by a tractor unit, said container body having an elongated recessed indentation extending horizontally and adjacent to the roof line of said container body, the combination comprising: an elongated enclosure mounted within said indentation, said enclosure having a light transmissive surface facing outward from said container body, said enclosure having a light reflective internal surface opposite said light transmissive surface; at least one elongated fiber-optic cable mounted within said enclosure to illuminate the interior of said enclosure and transmit light through said light-transmissive outward-facing surface, said fiber-optic cable having core and cladding materials which cooperate to support light propagation along the length of said cable and also radially outward to provide said enclosure illumination; a light source arranged to illuminate an end of said optic cable; and a translucent strip inserted into said enclosure between said outward-facing light transmissive, outward-facing surface and said fiber-optic cable, said strip containing message characters visible from outside said container body, said translucent strip thereby being back-lighted.

Claim 3

The combination according to claim 1 in which two fiber-optic cables are mounted generally parallel within said enclosure and are vertically spaced for illuminating said enclosure interior and therefore said translucent strip uniformly.

Claim 4

The combination according to claim 2 in which said fiber optic cables are each contained in a reflective plastic channel with a translucent channel cap thereover for illuminating the interior of said enclosure and, therefore, said translucent strip.

Claim 5

The combination according to claim 3 in which said reflective plastic channels and said translucent channel caps and said channels have mating sawtooth surfaces to lock together upon application of a mating force.

Claim 6

The combination according to claim 1 in which a portion of said translucent strip is colored translucent plastic material at a predetermined location along the length of said elongated enclosure to provide clearance lighting.

Claim 7

The combination according to claim 3 in which a portion of said translucent plastic strip is of a predetermined color over a predetermined portion of its length to provide clearance lighting.

Claim 8

A combined lighted message and clearance lighting system for installation within an elongated trough extending generally horizontally and adjacent to the roof line of a cargo vehicle container body comprising: an elongated enclosure mounted within said trough, said enclosure having illuminating means therein in the form of at least one end-illuminated, correspondingly elongated fiber-optic cable of the type having a translucent core surrounded by continuous translucent cladding, said core and cladding cooperating to provide outward light transmission and light propagation along the length of said cable to illuminate the interior of said enclosure; a translucent outward facing side of said enclosure providing a window for emission of said light laterally outward; first means comprising a partially translucent strip containing message information, said strip being associated with said window to provide an illuminated message visible outside said cargo vehicle; and second means associated with said partially translucent strip for producing a colored light emission along a predetermined portion of said translucent strip to provide clearance lighting.

Claim 9

A combined lighted message and clearance lighting system for installation within an elongated trough extending generally horizontally and adjacent to the roof line of a cargo vehicle container body comprising: an elongated enclosure mounted within said trough, said enclosure having illuminating means therein in the form of at least one end-illuminated, correspondingly elongated fiber-optic cable of the type having a translucent core surrounded by continuous translucent cladding, said core and cladding cooperating to provide outward light transmission and light propagation along the length of said cable to illuminate the interior of said enclosure; a translucent outward facing side of said enclosure providing a window for emission of said light laterally outward; first means comprising a partially translucent strip containing message information, said strip being associated with said window to provide an illuminated message visible outside said cargo vehicle; and second means associated with said partially translucent strip for producing a colored light emission along a predetermined portion of said translucent strip to provide clearance lighting.

Claim 10

The combination according to claim 7 in which said at least one fiber-optic cable is at least two end-illuminated fiber optic cables extending generally parallel over substantially the entire length of said enclosure.

Claim 11

The combination according to claim 7 in which said end illumination is provided by an enclosed light source at a central location along the front of said container body and said at least one fiber-optic cable comprises two cables running generally parallel within said enclosure on each side of said container body.

Claim 12

In a highway cargo vehicle including at least one chassis-mounted container body adapted to be drawn by a tractor unit, said container body having an elongated, recessed indicator extending horizontally and adjacent to the roof line of said container body, the combination comprising: an elongated enclosure mounted within said indentation, said enclosure having a light-transmissive surface facing outward from said body; a pair of elongated light-transmitting fiber-optic cables mounted with said enclosure to illuminate the interior of said enclosure and transmit light through said light-transmissive outward-facing surface, said fiber-optic cables having core and cladding materials which cooperate to support light propogation along the length of said cables and also laterally outward to provide said enclosure illumination; a light source for illuminating one end of said optical cables; means composing a reflective plastic channel for supporting each of said fiber-optic cables within said enclosure in generally parallel and vertically spaced relationship; a translucent channel cap for each of said reflective channels, said channels and said channel caps having mating sawtooth surfaces to lock together upon application of a mating force; a translucent strip inserted into said enclosure between said outward-facing surface and said cable channel caps, said strip containing message characters which are thereby back-lighted to be visible from outside said container body.

Claim 13

In a highway cargo vehicle including at least one chassis-mounted container body adapted to be drawn by a tractor unit, said container body having an elongated, recessed indicator extending horizontally and adjacent to the roof line of said container body, the combination comprising: an elongated enclosure mounted within said indentation, said enclosure having a light-transmissive surface facing outward from said body; a pair of elongated light-transmitting fiber-optic cables mounted with said enclosure to illuminate the interior of said enclosure and transmit light through said light-transmissive outward-facing surface, said fiber-optic cables having core and cladding materials which cooperate to support light propogation along the length of said cables and also laterally outward to provide said enclosure illumination; a light source for illuminating one end of said optical cables; means composing a reflective plastic channel for supporting each of said fiber-optic cables within said enclosure in generally parallel and vertically spaced relationship; a translucent channel cap for each of said reflective channels, said channels and said channel caps having mating sawtooth surfaces to lock together upon application of a mating force; a translucent strip inserted into said enclosure between said outward-facing surface and said cable channel caps, said strip containing message characters which are thereby back-lighted to be visible from outside said container body.
