Abstract

A combined center high mounted stop lamp and cargo lamp assembly for pick-up trucks, vans and the like, including a unitary integral molded laterally elongated casing member to be mounted on a truck cab, van, or the like, shaped to provide an exterior hood-like collar formation defining an encircling surround about a horizontal transverse elongated plural lamp zone for three side-by-side lamps. Three truncated substantially parabolic reflector cellular formations extend from the collar formation toward the front of the vehicle in use position defining lamb-bulb-housing reflector cavities directing light rearwardly of the vehicle and being provided with reflective metal coatings on the inner surfaces thereof. A red lens is supported by said collar formation in rearwardly covering relation to the centermost cellular formation and white lenses are provided for the other two cellular formations.

Claims

1. A combined center high mounted stop lamp and cargo lamp assembly for vehicles to be mounted on a rearwardly facing wall surface of the vehicle body near the top thereof at the transverse center of the vehicle, comprising a unitary integral molded laterally elongated casing member to be mounted on said rearwardly facing wall surface, the casing member being formed with an exterior hood-like collar formation defining an encircling surround about a horizontal transverse elongated plural lamp zone for three side-by-side lamps and the casing member including three substantially parabolic reflector cellular formations extending from the collar formation toward the front of the vehicle as three protruding reflector-forming bulges, the walls of said reflector cellular formations being shaped to define lamp-bulb-housing reflector cavities directing light rearwardly of the vehicle and being provided with reflective metal coatings on the inner surfaces thereof, a lamp bulb removably mounted in the forwardmost portion of the bulge-forming wall of each cellular formation along a principal optical axis of each, and a lens supported by said collar formation in rearwardly covering relation to each respective reflector cavity of the cellular formations, the lens for the centermost cellular formation being a red lens and the lenses for the other two cellular formations in flanking relation therewith being clear lenses, the walls of the cellular formations being of substantially parabolic contour in horizontal cross-section extending along a convex path protruding toward the front of the vehicle from the collar formation and joining a transverse substantially vertical interior partition thereof by short wall sections perpendicular thereto.

2. A combined stop lamp and cargo lamp assembly as defined in claim 1, wherein said cellular formations include substantially horizontal parallel top and bottom walls perpendicular to said interior partition.

3. A combined stop lamp and cargo lamp assembly as defined in claim 1, wherein said red lens of the stop lamp is supported in a substantially vertical plane when the assembly is in use position and said clear lenses of the cargo lamps are disposed in a plane inclining upwardly and rearwardly of the vehicle relative to the plane of the red lens.

4. A combined stop lamp and cargo lamp assembly as defined in claim 2, wherein said red lens of the stop lamp is supported in a substantially vertical plane when the assembly is in use position and said clear lenses of the cargo lamps are disposed in a plane including upwardly and rearwardly of the vehicle relative to the plane of the red lens.

5. A combined stop lamp and cargo lamp assembly as defined in claim 1, wherein the inwardly facing surfaces of the reflector cavities defined by said cellular formations are covered with a vacu-metalized deposit providing said reflective metal coatings thereon.

6. A combined stop lamp and cargo lamp assembly as defined in claim 2, wherein the inwardly facing surfaces of the reflector cavities defined by said cellular formations are covered with a vacu-metalized deposit providing said reflective metal coatings thereon.

7. A combined stop lamp and cargo lamp assembly as defined in claim 3, wherein the inwardly facing surfaces of the reflector cavities defined by said cellular formations are covered with a vacu-metalized deposit providing said reflective metal coatings thereon.

8. A combined stop lamp and cargo lamp assembly as defined in claim 4, wherein the inwardly facing surfaces of the reflector cavities defined by said cellular formations are covered with a vacu-metalized deposit providing said reflective metal coatings thereon.

9. A combined stop lamp and cargo lamp assembly as defined in claim 1, wherein said exterior hood-like collar formation is provided by a recurved flange extending rearwardly relative to the vehicle from adjacent said lenses to a return bend defining a rounded border framing the three side-by-side lenses, and the recurved flange then extending forwardly of the vehicle to an abutment edge shaped to conform to and be sealed against a confronting surface of said upper vehicle wall portion.

10. A combined stop lamp and cargo lamp assembly as defined in claim 2, wherein said exterior hood-like collar formation is provided by a recurved flange extending rearwardly relative to the vehicle from adjacent said lenses to a return bend defining a rounded boarder framing the three side-by-side lenses, and the recurved flange then extending forwardly of the vehicle to an abutment edge shaped to conform to and be sealed against a confronting surface of said upper vehicle wall portion.

11. A combined stop lamp and cargo lamp assembly as defined in claim 3 wherein said exterior hood-like collar formation is provided by a recurved flange extending rearwardly relative to the vehicle from adjacent said lenses to a return bend defining a rounded border framing the three side-by-side lenses, and the recurved flange then extending forwardly of the vehicle to an abutment edge shaped to conform to and be sealed against a confronting surface of said upper vehicle wall portion.

12. A combined stop lamp and cargo lamp assembly as defined in claim 4, wherein said exterior hood-like collar formation is provided by a recurved flange extending rearwardly relative to the vehicle from adjacent said lenses to a return bend defining a rounded border framing the three side-by-side lenses, and the recurved flange then extending forwardly of the vehicle to an abutment edge shaped to conform to and be sealed against a confronting surface of said upper vehicle wall portion.

13. A combined stop lamp and cargo lamp assembly as defined in claim 8, wherein said exterior hood-like collar formation is provided by a recurved flange extending rearwardly relative to the vehicle from adjacent said lenses to a return bend defining a rounded border framing the three side-by-side lenses, and the recurved flange then extending forwardly of the vehicle to an abutment edge shaped to conform to and be sealed against a confronting surface of said upper vehicle wall portion.

14. A combined center high mounted stop lamp and cargo lamp assembly for vehicles to be mounted on a rearwardly facing wall surface of the vehicle body near the top thereof at the transverse center of the vehicle, comprising a unitary integral molded laterally elongated casing member to be mounted on said rearwardly facing wall surface, the casing member being formed with an exterior hood-like collar formation defining an encircling surround about a horizontal transverse elongated plural lamp zone for three side-by-side lamps and the casing member including three substantially parabolic reflector cellular formations extending from the collar formation toward the front of the vehicle as three protruding reflector-forming bulges, the walls of said reflector cellular formations being shaped to define lamp-bulb-housing reflector cavities directing light rearwardly of the vehicle and being provided with reflective metal coatings on the inner surfaces thereof, a lamp bulb removably mounted in the forwardmost portion of the bulge-forming wall of each cellular formation along a principal optical axis of each, and a lens supported by said collar formation in rearwardly covering relation to each respective reflector cavity of the cellular formations, the lens for the centermost cellular formation being a red lens and the lenses for the other two cellular formations in flanking relation therewith being clear lenses, said exterior hook-like collar formation being provided by a recurved flange extending rearwardly relative to the vehicle from adjacent said lenses to a return bend defining a rounded border framing the three side-by-side lenses, and the recurved flange then extending forwardly of the vehicle to an abutment edge shaped to conform to and be sealed against a confronting surface of said upper vehicle wall portion.
