Abstract

A self-illuminated ornamental grill to be mounted between the pair of headlamps of a passenger car, comprising an elongate grill body and an elongate lens which are joined to each other to define a watertight lighting chamber. A pair of fog lamp assemblies or equivalent light sources are mounted in the lighting chamber so as to illuminate the complete length of the lens.

Claims

1. A self-illuminated grill for a motor vehicle of the type having a pair of headlamps disposed in horizontally spaced apart positions on the front end of a vehicle body, comprising:

(a) an elongate grill body to be mounted to the vehicle body so as to be disposed horizontally between the pair of headlamps, the grill body being generally open forwardly of the motor vehicle;

(b) an elongate lens mounted to the open front side of the grill body and coacting therewith to define an enclosed lighting chamber; and

(c) said headlamps disposed in the lighting chamber for illuminating substantially the complete length of the lens.

2. The self-illuminated grill of claim 1 wherein the light source means comprises a pair of lamp assemblies mounted in horizontally spaced apart positions in the lighting chamber and coacting to illuminate substantially the complete length of the lens.

3. The self-illuminated grill of claim 2 wherein each lamp assembly comprises:

(a) a reflector mounted to the grill body; and

(b) a light bulb replaceably mounted to the reflector.

4. The self-illuminated grill of claim 3 further comprising:

(a) mounting means for mounting the reflector of each lamp assembly to the grill body for pivotal motion about a horizontal axis extending longitudinally of the grill; and

(b) lamp tilting means for adjustably tilting each lamp assembly about the horizontal axis with respect to the grill body.

5. The self-illuminated grill of claim 4 wherein the lamp tilting means comprises:

(a) a male threaded member rotatably extending through the grill body;

(b) a female threaded member mounted to the reflector of each lamp assembly and engaged with the male threaded member; and

(c) resilient means acting between the grill body and the reflector for biasing them away from each other.

6. The self-illuminated grill of claim 4 wherein the mounting means comprises:

(a) a pair of reflector seats of elastic material on the grill body; and

(b) a pair of fastener elements fastening the reflector of each lamp assembly to the grill body via the respective reflector seats, the reflector seats being capable of elastic deformation to permit the reflector to pivot about the horizontal axis.

7. The self-illuminated grill of claim 2 wherein the grill body has a reflective surface formed at least between the pair of lamp assemblies.

8. The self-illuminated grill of claim 1 further comprising:

(a) a vent tube formed on the grill body for ventilating the lighting chamber; and

(b) a U shaped extension tube coupled to the vent tube for preventing the intrusion of water into the

lighting chamber.

9. A self-illuminated grill for a motor vehicle, comprising:

(a) an elongate grill body;

(b) an elongate lens joined to the grill body and coacting therewith to define a lighting chamber;

(c) a pair of lamp assemblies disposed in the lighting chamber and spaced from each other in the longitudinal direction of the grill for illuminating the complete length of the lens, each lamp assembly being mounted to the grill body for pivotal motion about an axis extending longitudinally of the grill; and

(d) lamp tilting means for adjustably tilting each lamp assembly about the horizontal axis with respect to the grill body.

10. The self-illuminated grill of claim 9 wherein the grill body is formed to include a first reflective surface between one end thereof and one of the lamp assemblies, a second reflective surface between air of lamp assemblies, and a third reflective surface between the other end of the grill body and the other of the lamp assemblies.

11. The self-illuminated grill of claim 10 wherein the lamp assemblies include reflectors accommodated in recesses in the grill body, one of the recesses being disposed between the first and second reflective surfaces and the other recess between the second and third reflective surfaces, whereby the complete length of the lens appears illuminated as the first, second and third reflective surfaces of the grill body and the reflectors of the lamp assemblies reflect the daylight.
