Description

[Detailed Description of the Invention] A. Technical field of the present invention The present invention relates to a vehicle lamp incorporating an inner lens, and sometimes to a specific structure of a fixing means for the inner lens.

B. Prior Art Referring to FIG. 2, the structure of a conventional vehicle light with a built-in inner lens will be described.
Fit the legs 5, 5' of the outer lens 3 into the outer groove 2 of the two inner and outer grooves 2, 2' formed on the circumferential side of the outer lens, and fit the legs 5, 5' of the inner lens 4 into the inner groove 2' of the outer lens 3. The grooves 2 and 2' are filled with fillers 6 and 6', respectively, to maintain sealing. However, this filler 6,
6' is made of hot melt or the like, and it is difficult to maintain stable adhesion over a long period of time. In other words, the adhesive effect weakens due to temperature changes in the natural environment, and during use,
Since the inner lens 4 moves in the direction of the arrow in the figure due to vibrations, etc., and the sealing is damaged, a square bar-shaped spacer piece 7 is formed inside the outer lens 3, as shown in figure C, to reduce the distance. Either the inner lens 4 is restrained from moving by the piece 7, or a step 8 is formed inside the outer lens 3 as shown in FIG. We are taking measures to do so.

C. Problems with the Prior Art However, even if the spacing piece 7 described in FIG. When viewed from the front, the area of the spacing piece 7 appears to be darkened as shown in Figure A, giving a poor appearance, and the welding area is raised, impairing transparency. Either method has drawbacks such as narrowing the light emitting area of the inner lens 4.

D. Purpose of the present proposal This proposal aims to eliminate the above-mentioned drawbacks as much as possible, and aims to widen the light emitting portion of the inner lens 4 while ensuring secure fixation.

E. Main points of the proposal This proposal replaces the outer lens 3 with the inner lens 4.
It is characterized in that it is fixed with a single screw 10.

F. Embodiment of the present invention Figure 1 is a cross-sectional view of essential parts showing an embodiment of the present invention.
First, in Figure A, the same parts as those of the conventional model described in Figure 2 are given the same reference numerals, and the features of the present invention are described in detail. As shown in the solid perspective view in FIG. 1 D, on the inside of the leg 5',
Positioning protrusions 9 each having an integrally formed bulge shape
(upper side in the figure), 9' (also lower side) are formed in the longitudinal direction, and in the groove 2 formed in the lamp body 1,
When each leg 5, 5' is fitted, each of the positioning protrusions 9, 9' creates a predetermined gap between the inside of the leg 5 and the outside of the leg 5' suitable for screwing a screw to be described later. The dimensions of the groove portion 2 are determined in advance so that the groove portion 2 is formed.

In addition, 10 is a screw drilled in the center of the bottom of the groove 2, 11 is a screw hole, 6, 6' is a filling material,
Show each.

G. Effects of the present invention The present invention has the above-mentioned configuration.Next, we will discuss the operation and effect as well as the manner of assembly.First, each leg portion 5 of the outer lens 3 and the inner lens 4 is attached to the groove portion 2 of the lamp body 1. 5' is fitted until it reaches the bottom of the groove, but at this time, each of the legs 5, 5'
Each positioning protrusion 9, 9' formed on the inside and outside of the
Since it is restrained on both inner sides of the groove 2 and inserted so as to be located in the center of the groove 2, and an interval suitable for screwing the screw 10 is formed between each leg, the screw hole 11 It is sufficient to screw the screw 10 into the gap and fix it.

Note that the filling materials 6, 6' are placed in the groove 2 at each leg 5, 6'.
Before inserting the tube 5', it may be applied to the inner and outer tips of each leg, or an appropriate amount may be placed on both sides of the bottom of the groove 2.

In this case, as described above, each of the lenses 3,
By simply fitting the legs 5, 5' of 4 into the groove 2, the positioning protrusions 9, 9' automatically create a gap suitable for screwing the screw 10 between the legs. The inner lens 4 and the outer lens 3 can be fastened together at the same time by simply screwing in and fixing the screws 10, and the screws 10 can fully penetrate into the gaps formed between the inner and outer surfaces of the legs 5, 5'.
Fastening and fixing can be done easily and reliably, and unlike conventional types, there is no need for spacing pieces 7 or step portions 8, so there are no spots with poor transparency, and the appearance is improved.
The appearance is good, the light-emitting portion of the inner lens 4 can be made wider, and the purpose of the present invention can be fully achieved.

Note that the device shown in FIG. 1B is different from the one described in FIG.
is formed on the inner and outer sides of each leg portion 5, 5',
This is integrally formed on the bottom peripheral side of the groove portion 2, that is,
The one shown in FIG. A positioning hole 13 consisting of a band-shaped groove with a diameter is formed, and the tips of the legs 5 and 5' are fitted into this positioning hole 13. The tips of the legs 5, 5' are still constrained to maintain a predetermined gap between them, and therefore, there is no difference in the operation and effect of being able to securely fasten the screws 10.
