Description

[Detailed description of the invention] <<Industrial Application Field>> This invention relates to a vehicle lamp such as a traffic light.

<<Prior Art>> FIGS. 4 and 5 show an example of such a conventional vehicle lamp. This lamp is constructed by attaching a front lens 3 to the front surface of a housing 4, which is made by joining a white lens 2 for a back-up lamp to an opening 1a in the center of a red lens 1 for a dummy. A leg portion 5 having an outward flange 5a at its tip is formed around the white lens 2, and the flange 5a is connected to the opening 1a of the red lens 1.
Both lenses 1 and 2 are joined by ultrasonic welding to the tips of the peripheral leg portions 6 over the entire circumference.

The housing 4 includes a flat flange portion 7 corresponding to the red lens 1 and a rearwardly protruding lamp chamber 8 corresponding to the white lens 2. A lamp bulb 9 is disposed within the lamp chamber 8. A groove 10 is formed on the entire periphery of the flange portion 7 of the housing 4, and a leg portion 11 formed on the entire periphery of the red lens 1 is inserted into the groove 10 and filled in the groove 10. They are joined by hot melt 12.
Further, a boss 13 is provided protruding from the back surface of the red lens 1, and a screw 14 is screwed into this boss 13 from the outside of the housing 4.

<<Problem to be solved by the invention>> In such a vehicle lamp, the hot melt 12 that joins the front lens 3 to the housing 4 is
The purpose of this is to provide a seal, not to secure a secure fixation. Reliable fixing is achieved by a screw 14 other than the hot melt 12. If fixing with the screw 14 is done from the front lens 3 side, the appearance will be spoiled, so it is generally done from the housing 4 side. For this reason, the boss 13 is absolutely necessary on the front lens 3. However, this boss 1
No. 3 had a problem in that it appeared on the surface of the front lens 3 as a darker colored part than other parts as shown in FIG. 4, spoiling the appearance of the front lens 3.

Therefore, an object of this invention is to provide a vehicle lamp having a structure that allows the front lens to be fixed to the housing without damaging the appearance of the front lens.

<Means for Solving the Problems> The vehicle lamp according to this invention is a vehicle lamp in which a front lens formed by bonding a plurality of lenses is attached to the front surface of a housing, and one of the plurality of lenses is attached to the front surface of a housing. A supporting half piece is provided at the tip of the leg of the lens, and another supporting half piece is provided in the housing that abuts against this supporting half piece, and a slit hole is provided in each abutting surface for inserting and supporting a slide bolt from one side. It is characterized in that both support halves are connected by inserting a slide bolt into the slit hole.

《Function》 The slide bolt for fixing the lamp to the car body panel is originally provided on the lamp.
The lens and housing are fixed using this slide bolt. A support half provided on the lens leg to support the slide bolt is not visible from the lens surface.

<<Embodiment>> An embodiment of this invention is shown in FIGS. 1 and 2. This lamp is the same as the lamp shown in FIGS. 4 and 5 except for the lens fixing structure, so similar parts will be described using the same reference numerals.

The central part of the dummy red lens 1 has an opening 1a.
is formed, and a white lens 2 is bonded thereto to constitute a front lens 3. The red lens 1 and the white lens 2 are joined together by connecting the outward flange 5a of the tip of the leg 5 formed on the periphery of the white lens 2 to the tip of the leg 6 formed on the periphery of the opening of the red lens 1. This is done by sonic welding.

The housing 4 consists of a flat flange portion 7 corresponding to the red lens 1 and a rearwardly protruding lamp chamber 8 corresponding to the white lens 2. It is set up. A groove 10 is formed on the periphery of the flange portion 7 of the housing 4, and the leg portion 11 formed on the periphery of the red lens 2 is inserted into this groove 10, and the hot melt 12 is inserted into the groove 10.
are joined by. A boss portion 11a is provided on a portion of the leg portion 11 apart from the red lens 2, and a screw 14 is screwed into this boss portion 11a from the outside of the housing 4. Also white lens 2
As shown in FIG. 3, a bracket 16 having an outwardly facing support half 15 is formed downward from the tip of one side of the flange 5a. A bracket 18 with a support half 17 oriented laterally is also formed downwardly. Both support halves 15,1
In the abutting surfaces 15a and 17a of 7, slit holes 19 and 20 are provided in half symmetrically so that the whole is unified. Slit hole 1
9 and 20 are slits 19a and 20 for inserting the neck portion 21a of the slide bolt 21 from one side.
a, a horizontal hole 19b for supporting the neck 21a,
20b. Therefore both support halves 15,
The abutment surfaces 15a, 17a of 17 are abutted against each other, and the slide bolt 21 is inserted into the slits 19, 2.
0, both support halves 15 and 17 are sandwiched and coupled between the flanges 21b and 21c of the slide bolt 21, and the front lens 3 is fixed to the housing 4.

In the lamp thus assembled, the vehicle body panel 22 is fixed via the slide bolt 21.

Since the boss portion 11a formed on the red lens 1 and the bracket 16 and support half piece 15 formed on the white lens 2 are not visible from the surface of the front lens 3, the appearance of the front lens 3 is not impaired.

The fixation using the boss portion 11a and the screw 14 may be omitted, and the fixation may be performed using only a plurality of support half-piece structures.

《Effects of the invention》 As mentioned above, the vehicle lamp according to this invention has the following effects:
A support half piece is provided at the tip of the leg of one of the plurality of lenses joined, and another support half piece is provided in the housing that abuts against this support half piece, and a slide bolt is inserted from one side into each abutting surface. A slit hole was provided for insertion and support, and a slide bolt was inserted into this slit hole to connect both support halves, so that the lens was securely fixed to the housing, and the support half provided on the lens was removed from the lens surface. It is invisible and does not damage the appearance of the lens.
