Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a vehicle lamp equipped with a rim.

<<Prior Art>> The vehicle lamp shown in FIG. 5 is an example of a rear combination lamp of an automobile. This lamp is
The entire structure is horizontally elongated, and consists of a tail stop lamp 1 on the main part, a turn signal lamp 2 on the right side, and a backlight lamp 3 on the left side.The periphery of the lamp is covered with a rim 4 except for the left side, and A cover 5 is attached to the.

The rim 4 is fixed with screws 6 at four places on the upper side and four places on the lower side. More specifically, as shown in FIG. 6, bosses 7 formed at predetermined intervals at the base end of the rim 4 are fixed to flanges 9 formed around the front opening of the housing 8 with screws 6. A groove 10 is formed on the entire inner peripheral edge of the flange 9, and a lens 11 is placed inside the groove 10.
The leg portions 12 are adhesively fixed with a sealant 13. A predetermined distance g is provided between the tip of the rim 4 and the peripheral edge of the lens 11 from a design standpoint.

<<Problem to be solved by the invention>> In the case of such a horizontally long lamp, the distance g between the tip of the rim 4 and the peripheral edge of the lens 11 is required to be uniform in the entire horizontal direction. . This =
This is because the space g was originally provided from a design standpoint. In the illustrated lamp, as shown in FIG.
are formed perpendicularly to the end surface 4b of the tip of the rim 4 and the end surface 11a of the peripheral edge of the lens 11, respectively, to obtain a constant distance g.

However, if the rim 4 is thin with a basic wall thickness of about 2.5 mm, it is difficult to obtain flatness of the end surface 4a or 9a, so when the two are tightened with the screw 6, the tip of the rim 4 may lift up. There was a problem that a certain distance g could not be obtained due to sinking. Moreover, this is not just a design problem; if the lower edge of the trunk lid is located above the rim 4, a predetermined distance required for safety cannot be obtained between the lower edge of the trunk lid and the rim 4. There are also problems.

SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide an improved vehicle lamp which ensures a constant gap between the tip of the rim and the periphery of the lens.

<Means for Solving the Problems> The vehicle lamp according to this invention has an inclined surface facing inward on the end face of the rim base end or the flange face of the housing when the rim base end is screwed to the flange of the housing. In addition, it is characterized in that a protrusion for forming a certain gap is provided on one of the opposing surfaces between the rim tip and the lens peripheral edge.

<<Operation>> When the base end of the rim or the flange surface is tilted inward and the two are screwed together, the tip of the rim is pressed against the peripheral edge of the lens, and the flange surface provided on one of the opposing surfaces of the tip of the rim or the peripheral edge of the lens is pressed against the lens peripheral edge. The protrusion always provides a constant distance between the two.

<<Example>> FIG. 1 shows an example of this invention. This lamp is a horizontally elongated rear combination lamp similar to that shown in FIG. 5, and has a flange 22 formed around the front opening of a housing 21. A groove 23 is formed on the inner peripheral edge of the flange 22 , and a leg 25 of a lens 24 is adhesively fixed in the groove 23 with a sealant 26 . Flange 22
A rim 27 is fixed to the outer peripheral edge of the rim 27 by a screw 28, which is a tapping screw, and a cover 29 is further fixed thereon. A lamp bulb 34 is arranged inside the lamp chamber.

As shown in FIG. 2, the rim 27 has bosses 30 formed at appropriate locations, and guide holes 31 into which the screws 28 are screwed. Also,
Flange surface 2 at a position opposite to this guide hole 31
A screw insertion hole 32 is formed in the rim 2a, and the rim 2 of the lens 24 periphery corresponding to this position is formed in the rim 2a.
A protrusion 33 is formed on the surface facing the tip of the rim 27, with which the tip of the rim 27 comes into contact. and rim 27
The end surface 27a of the base end is inclined inward.

Since this lamp is constructed as described above, when the end surface 27a of the base end of the rim 27 is brought into contact with the flange surface 22a opposite thereto, the screw 28 is screwed into the guide hole 31 through the insertion hole 32 and tightened. As shown in FIG. 3, the rim 27 receives a downward moment as the inclined end surface 27a of the base end tries to follow the flat flange surface 22a.
The tip thereof is pressed downward and comes into pressure contact with the protrusion 33 on the peripheral edge of the lens 24 . As a result, the rim 27
The distance g between the tip and the peripheral edge of the lens 24 is always constant over the entire lateral direction of the lamp.

In the above embodiment, the end surface 27a of the base end of the rim 27 is
is an inclined surface, but as shown in FIG. 4, the end surface 27a
is a flat surface, and the flange surface 22a opposite to this is a flat surface.
The protrusion 33 provided on the peripheral edge of the lens 24 may be an inclined surface facing inward.
It may be provided on the surface 27b of the distal end of the rim 27 facing the four peripheral edges.

《Effects of the invention》 As mentioned above, the vehicle lamp according to this invention has the following effects:
Either the proximal end surface or the flange surface of the rim that is screwed to the flange surface of the housing is an inwardly inclined surface, and the rim is provided with an inward slope on either the distal end or the lens periphery opposite thereto. Since a protrusion is provided to keep the distance constant, the distance between the tip of the rim and the peripheral edge of the lens can be kept constant by simply screwing the rim to the flange.
