Description

[Detailed description of the invention] (a) Technical field of the present invention The present invention relates to a vehicular lamp, and in particular to the structure of a specific fixing portion formed on the lamp for fixing a lens fitted to the lamp.

B. Prior art Regarding the specific means of attaching the lens and rim to the lamp body that has been used in the past, referring to FIG. The lamp body P is a sealing portion formed in the shape of a groove that opens forward on the outer peripheral side of the lamp body B, and the bottom surface thereof is extended so as to protrude further outward into a plate shape.

The circumferential side of the lens _L0 is fitted into the sealing part P via a filler, and a rim R is disposed on the outer circumferential side of the lens _L. As shown in Fig. 6, the rim R has screws b, respectively.
It is screwed onto the bottom surface of the sealing part P of the lamp body B and its extension.

C. Problems of the prior art However, in such a configuration, the peripheral side of the lens L is screwed from the rear through the filler, and the rim R disposed on the outer peripheral side is also screwed together with the screw b. This has the advantage that the fixed state is firm, but on the other hand, fixing the lens L ₀ and rim R individually with screws increases the assembly man-hours, and separately installing the rim R increases the number of parts. However, it is difficult to say that the workability is good, and it has the disadvantage that it is not suitable for an assembly line production system.

D. Purpose of the Proposal This Proposal aims to eliminate the defects in the design as much as possible, and aims to reduce the number of parts, improve assembly workability, and provide an inexpensive product.

E. Main Points of the Proposal This proposal is characterized in that a locking claw is integrally connected to the lamp body, and the locking claw is formed to act as a rim that also serves as a lens holder with a protrusion at the tip. have

F. Embodiment of the present invention Figure 1A is a sectional view of a main part showing an embodiment of the present invention, and Figure 1B is an enlarged sectional view of the x section in Figure 1A, which is different from the conventional type described in Figure 6. The same parts are given the same reference numerals, and only the different points of the proposal are explained in detail: _L1 is a locking pawl that is integrally connected to the outside of the sealing part P, and the locking pawl has a locking pawl that is connected to the surroundings of the lens _L0 . established in
A protrusion t with an inclined outer side is formed to improve the design appearance and also serve as a rim to fill the gap between the light body and the vehicle body to which the light body is attached.

h indicates a hinge formed inside the base of the locking claw _L1 .

G. Effects of the present invention The present invention has the above-mentioned configuration.Next, we will explain the operation and effect in detail along with the installation procedure of the present invention.As with the conventional type, a filler is put in the sealing part P, and the peripheral side of the lens _L0 is After fitting the lens into the state shown in Figure 1A, use the locking claws _L1 , which are integrally connected to the outside of the sealing part, to alternately point the front surface of the lens _L0 from either side in the direction of the arrow. Drive as shown,
It is sufficient to engage the protrusion with the front peripheral side of the lens _L0 as shown in the enlarged cross-sectional view in FIG.

According to the present invention, as described above, the locking pawl _L1 is integrally provided on the outside of the sealing portion P, and the locking pawl includes the following:
Since a hinge h is formed at the base and a protrusion t is formed at the tip, when the locking claw _L1 is engaged with the lens _L0 , it can be bent easily with extreme flexibility, and the sealing claw L1 can be easily bent. Insert the lens into the stop P via the filler.
Since the peripheral side of L ₀ locks the front surface of the lens, which is already in a fitted state, with the protrusion t, sufficient mechanical strength is not only obtained, but also the locking pawl L ₁ has an inclined surface on the outside of the protrusion t. Since it also serves as a rim, there is no need to attach the rim R to the outside of the sealing part P as in the conventional model, so there is no waste and the size can be reduced, and it also provides a light feeling. The completed state is shown in Fig. 3C, and although it has a simple structure, it produces excellent effects that can fully achieve the purpose of the present invention.

Note that the engagement between the lens L ₀ and the locking claw L ₁ is not limited to the configuration shown in FIG. _1B , but as shown in FIG. A protrusion t is formed, and both protrusions t and t' engage with each other to strengthen the engagement force. Furthermore, as shown in Figures B and C, the outer tip of the locking claw _L1 and the lens L It is also possible to make the front surface of the lens _{L 0} in close contact with the front surface of the lens L 0 to prevent dust from entering into that area.Also, as shown in Figure D, the outer tip of the locking claw L ₁ and the front surface of the lens L ₀ are the same. It is possible to arrange the appearance as a surface and further improve the design effect, etc. These things can be selected as appropriate as necessary.

Furthermore, in Fig. 3, the locking pawl also serves as a rim, and as shown in A of the same figure, the locking pawl _L2 is attached to the outside of the sealing part P via a hinge h formed on the outer surface thereof. They are integrally connected so as to have a U-shaped cross section, and are provided with a protrusion t on the inside thereof. On the other hand, the lens _L0 has a stepped portion d formed on its circumferential side, and the stepped portion has a locking claw _L2.
A recess is formed to strengthen the engagement with the protrusion t of the locking pawl, similar to the one described in FIG.
It is sufficient to simply fit and lock _L2 into the stepped portion d of the lens _L0 , and this state is shown in FIG.
When the outside of L ₂ is fitted (see Figure 3, left side),
Since it also functions as a rim, there is no need to separately install a rim as in the conventional type, and a particularly aesthetically pleasing appearance can be imparted, and the function and effect are the same as those shown in Figure 1 described above.

FIG. 4 is an actual perspective view showing an embodiment in which the shape of the locking pawl is further changed, and L ₃ is one sealing part P.
The locking pawl has a protrusion t formed on the outside of the other sealing part P, and t' is a protrusion formed on the outside of the other sealing part P. , which engages with the protrusion t of the locking claw _L3 ,
For example, three locking claws _L3 are formed in the longitudinal direction of the lens _L0 , and a stepped portion d' corresponding to the thickness of each locking claw _L3 is also formed on the lens _L0 , as shown in the same figure. As shown in the figure, the locking pawl _L3 is rotated in the direction of the arrow to be engaged and fitted to the protrusion t', thereby completing the process.

Furthermore, the one shown in FIG. 5 is also a modified example of the locking pawl with a different arrangement, and the locking pawl Lc is substantially the same as that shown in FIG. Although omitted, each of the locking claws La and Lb is thick enough to match the surface of the lens _L0 , and has notches K and K' on the outer surface of the tip, and each of the notches has a respective one. A protrusion t′ is formed respectively,
A small hole h is formed in the center of the inner side of the locking claw Lc to fix each of the protrusions t' from above when the locking claw Lc is folded, as will be described later. A recess E is formed so that the protrusion t is engaged therewith.

On the other hand, the lens L ₀ has a cross-shaped step d formed at an appropriate depth to accommodate the locking claws La, Lb, and Lc. Here, an example of the assembly procedure is shown. Specifically, in the state shown in Figure 5, first, one of the locking claws shown by the dotted line, for example La, and then Lb, are rotated in the directions of the arrows, and the lens L ₀ is rotated as shown in the figure. , and then rotate the locking claw Lc in the direction of the arrow to insert the projection t into the recess E so that the small hole h on the inner side of the center fits into the projection t'.
In this way, the protrusions t' of each of the locking claws Lb and Lc are restrained by the small holes of the locking claw Lc, and each of the locking claws L
itself is pressed and fixed by the locking claw Lc, and when the assembly is completed, the size is such that the lens L ₀ is fitted to the lamp body B, and the implementation shown in FIG. 4 above and this FIG. 5 is completed. The example shown in FIG. 3 is no different in operation and effect from the example shown in FIG.
