BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an automobile headlight the irradiation direction of which is freely adjusted upward, downward and from side to side.
BACKGROUND ART
In the case of conventional automobile headlights, there have been headlight assemblies composed of a downward headlight for short distance on the left and an upward headlight for long distance on the right, and a headlight with two types of built-in filaments in an electric bulb for use as one headlight designed to throw a light upward and downward.
Either of these two conventional automobile headlights is fixedly installed in its housing and adjustable only upward and downward, whether it is adjusted by human power or automatically by sensing the illumination of an automobile coming in the opposite direction in an electronic way.
Even when such conventional headlights direct the light downward, it is impossible for it to direct the light on the ground close to a front side of the vehicle due to its fixed degrees of irradiation angle.
The present invention aims to provide a headlight which can quickly throw a light in the direction to which the automobile turns by adjusting its irradiation angle from side to side and can also throw a light on the ground just thereunder when the automobile arrives at the top of a slope by setting its irradiation angle extremely downward.
SUMMARY OF THE INVENTION
An automobile headlight assembly of the present invention includes a housing having pivot means situated inside the housing to define a first axis. A bulb receiver is situated within the housing, the bulb receiver having an open front edge and means coupling the bulb receiver to the pivot defining means. A directing means is coupled to the bulb receiver to permit movement of the bulb receiver about the first axis in a generally horizontal plane. Pin means are provided on the bulb receiver to define a second axis generally orthogonal to the first axis. A unitary adjustable cover is situated inside the housing having a front edge positionable forward of the bulb receiver front edge. The adjustable cover includes means coupling the cover to the pin means on the outside of the bulb receiver. The adjustable cover also includes a slot defined by a pair of edges straddling one of the pivot means defining the first axis adjusting means is coupled to the cover for causing adjustment of the cover position about the second axis.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side elevation view showing an adjustable automobile headlight assembly according to one embodiment of the present invention.
FIG. 2 is a vertical sectional view of FIG. 1.
FIG. 3 is a top plan view of FIG. 1.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 and FIG. 2 are a side elevation view and a vertical sectional view of an automobile headlight assembly the irradiation direction of which is adjustable according to an embodiment of the present invention.
A terminal(3) is exposed at the rear end of a reflex mirror(2) with a lens(1) inserted into the front side. The base(5) of an electric bulb(4) with a bolt part(8) is combined with a socket(7) and a threaded part(6) formed therein.
A bulb receiver(9), which is open at its front side and at its rear end, includes confronting pivot suspensions(10)(11) in the upper and lower parts and is interlocked with the steering device of an automobile on the outer wall of the bulb receiver on the rear lower part and a socket means(14) is provided with a globular groove(13) into which a ball(12') on the end of working bar(12) is inserted.
The reflex mirror(2) and bulb receiver(9) will be fixed together under the condition that they are inserted into the inside of a socket(7), as shown in FIG. 2.
FIG. 3 is a plan view according o
