Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headlight for an automobile or the like, which has a reflecting mirror for supporting a glow lamp, and the reflecting mirror is fixed to a vehicle body in a casing. Has an annular groove which is supported on the casing and which extends annularly along the front edge of the casing, and which has an annular groove in or on the casing itself and in which the headlamp has an irradiation opening in the casing. A front glass covering the foot portion of the front glass fixed in the annular groove of the casing by an adhesive, and the headlamp integrally protruding from the groove side wall outside the annular groove of the casing. Has a plurality of locking members, which at one of its locking positions center the front glass in a direction perpendicular to the axis of the reflector, and on the other hand the foot of the front glass. Above annular groove And pressed against the bottom, and the cured adhesive is about of the type that secure the locking member to its locking position.

2. Description of the Related Art For example, German Patent Publication No. 3103057.
In the headlight known from U.S. Pat. No. 6,096,027, the locking member for fixing the front glass of the headlight is constructed as a spring tongue, each tongue extending in a plane perpendicular to the axis of the reflector. . The fact that the tongue is arranged in the above-mentioned right-angled plane is often a problem in many types of headlights.
This is because the spring tongue is visible over its entire length when the headlight is viewed from the front side, which may impair the overall appearance of the headlight. Moreover, since the spring tongue is in contact with the front glass of the headlight only in the middle portion of its entire length, the free end range beyond the contacting middle portion functions as a locking member. Not not.

Problem to be Solved by the Invention The problem to be solved by the present invention is to overcome the above-mentioned drawbacks in the prior art and to securely fix the front glass without impairing the overall appearance of the headlight. It is to be.

SUMMARY OF THE INVENTION According to the invention, according to the invention, a headlamp of the type mentioned at the beginning is provided with a hook in which each locking member extends in a tongue shape parallel to the axis of the reflector. Tongue of the hooked tongue, which comes into contact with the foot of the windshield from the outside to center the windshield in the direction perpendicular to the axis of the reflector and with the hook. The hook of the tongue is pressed on the rear side of the shoulder of the foot of the windshield to press the foot of the windshield against the bottom of the annular groove, and the foot of the windshield is pushed from the groove bottom of the annular groove. This is solved by the fact that at least three supporting ridges are raised.

EFFECTS OF THE INVENTION According to the present invention, the aforementioned problems in the prior art are solved, each tongue with hook functions as a locking member over its entire length, and when the headlight is viewed from the front, each hook The tongue shows only a very small part of it, so that the overall appearance of the headlamp is not impaired. Furthermore, the tongues with hooks center the front glass in a direction perpendicular to the axis of the reflector, and the foot of the front glass is pressed firmly against the bottom of the annular groove of the casing, so that the front glass is held securely in the casing. To be done.

Further, according to the matters described in claims 3 and 4, the problem of excessive adhesive metering is solved.

Further, in a so-called rectangular headlamp in which the horizontal dimension is several times the vertical dimension, for example, the thermal effect caused by the difference in the coefficient of thermal expansion of the mutually cooperating components is The function of the hooked tongue provided in the vertical range may be impaired, but such an obstacle is prevented by the configuration described in the fifth aspect.

EXAMPLE A rectangular headlight for a motor vehicle has a casing 10 which is fixed to the vehicle body 9 of the motor vehicle in a manner not shown. The casing 10 houses a reflecting mirror (not shown) that is common to the upper beam and the passing beam, and a reflecting mirror 11 for a fog light equipped with a glow lamp 12. A frame 13 having an annular groove 15 on the end face side is fixed to the casing 10 via a seal ring 14. The annular groove 15 receives the foot 17 of the windshield 18 which covers the irradiation opening of the casing 10. The foot portion 17 and the annular groove 15 have a rectangular configuration having a long side in the horizontal direction and a short side in the vertical direction when viewed from the direction of the reflecting mirror axis 19.

Two hooked tongues 20 integrally project forward from the groove side walls 16 on the outer sides of both the upper and lower sides, and each hooked tongue 20 is hooked inward toward the reflecting mirror axis 19. It has a hook 21 extending in a shape and an elastic tongue piece 22 extending forward in the direction of the reflector axis 19. On the groove bottom of the annular groove 15, a plurality of concave portions are formed instead of the annular slit 23 or the annular slit on the one hand, and on the other side, a plurality of raised portions 24 protruding forward are formed. On the groove side walls 16 outside the annular groove 15 on both left and right short sides of the rectangular frame 13 when viewed from the front,
Two pin-shaped portions 25 are integrally formed in parallel with the reflecting mirror axis 19.

The front glass 18 is permanently attached to the frame 13 as described below.

After the adhesive 26 is filled in the annular groove 15, the front glass 18 is guided into the annular groove 15 toward the frame 13 in the direction of the reflecting mirror axis 19. At this time, the edge portion 27 of the front glass protruding outside the foot portion 17 pushes the hook 21 outward. When the foot portion 17 occupies a predetermined position with respect to the frame 13 by supporting the foot portion 17 on the raised portion 24, the hook 21 moves to the rear side of the shoulder 28 of the edge portion 27 (front side of the windshield 18). Lock. During this assembly, the excess adhesive 26 is pushed into the slit 23. The four hooked tongues 20 and the four pin-shaped portions 25 abut the edge portion 27 from the outside or the side to center the front glass 18 in a direction perpendicular to the mirror axis 19. Furthermore, the hardening adhesive 26 forms an adhesive joint that secures the hooked tongue 20 and the pin 25 in a functional state.

Instead of the sealing ring 14 when the frame 13 is not needed, the casing 10 itself has an annular groove 15 for receiving the windshield 18.
