本発明は、車鞠用灯具、詳しくはランプを組込んだハウ
ジングの周綾部の溝部にレンズをシール剤により接着固
定した車鋼用灯具に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light for a car, and more particularly to a light for a car, in which a lens is adhesively fixed to a groove in the periphery of a housing in which the lamp is incorporated using a sealant.

構造上補強のためのボス部ｌａまたはピンｌｂを突設す
ることが不可能になることがある。In order to improve the reliability of the adhesive strength and prevent the lens from falling off, a boss portion la or pin lb is provided on the lens to protrude from the housing 3 around the housing 3 in which the lamp 2 is installed, as shown in FIGS. 1a and b. After adhering the leg part 11 of the lens 1 to the groove part 31 of the green part with the sealant 4, screw the screw 5 into the boss part la of the lens 1, or tighten the pin lb of the lens 1 by heat punching or ultrasonic waves to attach the lens. 1 is fixed to the housing 3, and the joint between the lens 1 and the housing 3 is reinforced. However, the smell of the conventional car sardine lamp mentioned above,
Since the lens 1 has a protruding boss portion la or pin lb for reinforcement, the structure of the lens 1 becomes complicated, and the boss portion la or pin lb may be damaged during molding of the lens 1. If there is a problem with the molding of the lens 1, and if the shape of the lens 1 becomes complicated due to a radius, it becomes impossible to protrude the boss portion la or pin lb for structural reinforcement. Sometimes.

鞠用灯具を提供せんとするものである。In addition, as shown in FIG. 1a, the leg portion 1 of the lens 1 is
There are cases where the boss part la has to be provided to protrude inward from the lens 1, which causes an appearance problem in that the boss part la is visible from the outside of the lens 1, and if the boss part la blocks the light from the lamp 2. There is a problem with light distribution. Therefore, if we stop tightening the screw 5 and caulking the pin described above and try to firmly join the lens 1 and the housing 3 using the sealant 4, it is necessary to increase the width of the adhesive groove 31 of the housing 3. , there are problems such as a reduction in the light emitting area of the lens 1. SUMMARY OF THE INVENTION The present invention aims to provide a lamp for a car wheel which has improved the above-mentioned drawbacks.

の車鋼用灯具の具体例を第２図乃至第４図を参照して説
明する。In the present invention, a thin wall portion is provided in the groove portion of the housing, and a tip of a resin rivet made of a resin of the same quality as the lens or a resin that is molten with the lens is pierced through the thin wall portion and welded to the lens, thereby forming a lens leg portion. The resin rivet is engaged with the back surface of the groove of the housing, and the lens is fixed to the housing via the resin rivet. Hereinafter, specific examples of the lamp for vehicle steel according to the present invention will be described with reference to FIGS. 2 to 4.

しかして、本発明の車鋼用灯具は、レンズ１とハウジン
グ３との接合強度を樹脂リベット６を使用して補強する
。Thus, in the car steel lamp of the present invention, the resin rivet 6 is used to reinforce the bonding strength between the lens 1 and the housing 3.
すなわち、この実施例において、レンズ１は透明で極性

強固に固定させる。The resin rivet 6 is made of a resin that is the same as the lens 1 or a resin that can be melted with the resin, or a resin that is more heat resistant than the polypropylene resin of the housing 3, such as PMMA or SA.
It is made of N or PC, and is formed from a welded part 61 and a locking part 62. Then, a thin wall portion 32 of a size that allows the welded portion 61 of the resin rivet 6 to be inserted is provided in the groove portion 31 of the housing 3, and a positioning protrusion 33 is protruded around the back surface of the thin wall portion 32. Fill the groove 31 of the housing 3 with the sealant 4, set the leg part 11 of the lens 1 in the groove 31, position the welded part 61 of the resin rivet 6 in the thin part 32 of the groove 31, and remove the resin rivet 6. By positioning the horn 7 of the ultrasonic welding machine on the back side of the resin rivet 6 and operating the ultrasonic welding machine, the resin rivet 6 is
The landing portion 61 of the housing breaks through the thin wall portion 32 of the housing, and the tip of the welded portion 61 of the resin rivet 6 connects to the leg portion 11 of the lens 1.
The resin rivet 6 and the lenses 1 are welded to the housing 3 and the engaging portion 62 of the resin rivet 6 is welded to the housing 3.
It engages with the positioning protrusion 33 on the back surface of the groove 31, thus firmly fixing the lens 1 and the housing 3 via the resin rivet 6.
本発明において、前記の如く溝部に肉薄部３２を形成し

を示す一部縦断面図である。In the present invention, the reason why the thin wall portion 32 is formed in the groove portion as described above is because if this portion is a through hole, the groove portion 31
This is because the sealant will flow out when the sealant 4 is filled in the groove.If this thin part is not present, even if the ultrasonic welding machine is operated, the resin rivet will break through the groove seat wall and the resin rivet will break. This is because it is not possible to integrally combine the legs with the lenses. FIG. 3 is a partial vertical sectional view showing another embodiment of the present invention.

構造が簡潔化され、レンズ成形が容易になり、レンズ形
状を自由に設計することが可能になる。As described above, in the present invention, a thin wall portion is provided in the groove portion of the housing, and the tip of a resin rivet made of a resin of the same quality as the lens or a resin that can be melted with the resin is pierced through the thin wall portion to connect the lens. By welding, the lens leg and the resin rivet are integrated, and the resin rivet is engaged with the back surface of the groove of the housing and fixed to the housing via the resin rivet, so that the lens and the housing are connected by the resin rivet. In addition, there is no need to protrude bosses or pins on the lens like in conventional car steel lamps, which simplifies the lens structure and facilitates lens molding. This makes it possible to freely design the lens shape.
また、ハウジングの溝部において補強するので、外観上
の問題はない。さらに、本発明はハウジングの溝部の幅
をシール性を考慮の上できる限り小さくしても十分な接
合強度が得られるので、レンズの発光面積の問題を解決
することができる。Further, since the groove portion of the housing is reinforced, there is no problem in appearance. Further, in the present invention, sufficient bonding strength can be obtained even if the width of the groove portion of the housing is made as small as possible in consideration of sealing performance, so that the problem of the light emitting area of the lens can be solved.
