DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase application corresponding to PCT/EP83/00179 filed Mar. 16, 1984 and based upon French application No. 82.12512 filed July 16, 1982 under the International Convention.
Field of the Invention
The invention relates to a headlamp with an adjustable reflector for motor vehicles, comprising a housing mounted on the body of the vehicle and a cover disc which is attached to the housing by means of a groove-rib connection. The housing carries a horizontally and vertically adjustable reflector.
BACKGROUND OF THE INVENTION
In known headlamps of this type the components for adjusting the pivoting the reflector occupy considerable space in the housing, particularly at the circumference of the reflector. This occupation of space reduces the effective illuminating aperture of the reflector in proportion to the available surface of the cover disc and prejudices the aesthetic appearance of the headlamp when it is not in service.
In order to eliminate this disadvantage, it has already been proposed to fit a molding on the housing around the edge of the reflector; however this complicates the construction of the headlamp without improving its efficiency.
OBJECT OF THE INVENTION
The principal aim of the invention is to overcome the disadvantages of known headlamps and to provide an improved headlamp, wherein The surface of the cover disc is utilised to the full and the adjusting devices occupy only a small space, and are furthermore virtually invisible from the exterior.
SUMMARY OF THE INVENTION
According to the invention, this object is achieved in a headlamp of the type previously defined when the reflector carries on its circumference a joint ball (ball joint), which rotates in a bearing connected to the housing on the cover disc, and an axle (shaft) which is located substantially in the same horizontal plane as the joint ball and is rotatable in a shoe which is secured in the housing with substantially horizontal sliding mobility, while bearing and shoe are accommodated in spaces which are located in alignment behind at least one groove-rib connection of the cover disc on the housing. The front closure of the spaces and the continuity of the shape of the connecting edge zone are achieved simultaneously by the packing of the bearing with an end profile of the groove and rib type and by the bent edge of at least one cover, for a partial section of the groove-rib connection, which closes at least the accommodation space of the shoe. The rear surface of the reflector carries an actuating rod, which is located in said horizontal plane, and a second actuating rod which is arranged in another horizontal plane. The adjusting parts are arranged substantially horizontally to the actuating rods.
The invention is described more fully with reference to the drawing, in which:
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is an elevation of a headlamp according to an exemplary embodiment of the invention;
FIG. 2 is a sectional view along the line II--II in FIG. 1;
FIG. 3 is a sectional view along the line III--III in FIG. 1;
FIG. 4 is a sectional view along the line IV in FIG. 2 on a larger scale, and
FIG. 5 is a sectional view along the line IV--IV in FIG. 1.
Specific Description
The headlamp according to the invention comprises a housing 1, which is connected to the body (not shown) by a front angle piece 2 and by rear screws 3. The housing 1 has a front aperture 4 which is framed by a groove 5. The aperture 4 is closed by a cover disc 6 on which a circumferential rib 7 is present which is secured in the groove 5 by means of an adhesive 8. The housing 1 also has a rear aperture 9, which is closed by a cover 10. A reflector 11, which carries an incandescent lamp 12 in a lamp holder 12', is arranged in the housing 1 so that it can be adjusted horizontally and vertically. Devices for this purpose are known and therefore need not be described in detail here.
According to the invention the reflector 11 exhibits at its circumference a substantially hor
