Abstract

(57) [Summary] [Purpose] In the conventional lens for vehicle lighting, when a coating surface is provided on a part of the flange, a flat surface must be provided at the boundary with the knurl. Due to the surface, the inside of the lighting fixture was seen through and the appearance was spoiled. According to the present invention, at least a part of the knurl 3 is a lens 1 having a simple knurl 4 in which the pitch P of the knurl 3 is divided into two, one of which is a textured surface 4a and the other of which is a transparent surface 4b. Thus, the simple knurling 4 which is formed as a whole flat surface allows the coating to be performed without impairing the adhesion of the masking jig even when the coating film 5 needs to be provided on a part of the flange 2. At the same time, the simple knurling 4 allows the knurling 3 to be viewed as if it were continuous, thereby solving the problem.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lens of a vehicular lamp, and more particularly, to a structure of a knurl provided on an inner surface of a flange portion of the lens for preventing see-through inside the lamp.

[0002]

[Prior art]

 FIG. 2 shows an example of a configuration of a lens 90 of a conventional vehicle lamp. In recent years, a sense of unity in design with the vehicle body is further required. A flange 91 is provided on the periphery of 90 for the purpose of emphasizing a sense of unity with the vehicle body, and the flange 91 is provided with a knurling process 92 for avoiding see-through. Depending on the requirements in 1), a coating film 93 of, for example, silver color may be formed on a part of the flange 91.

[0003]

[Problems to be solved by the device]

 However, in the lens 90 in which the knurl 92 and the coating film 93 are used together, when forming the coating film 93, it is necessary to cover an unnecessary portion with a masking jig, and at this time, the boundary line D between the two. If the knurls 92 are applied to such positions, the above-mentioned masking jig is lifted and the coating is circulated, resulting in a markedly impaired appearance.

As a means for preventing the above, the knurl 92 is omitted in the vicinity of the boundary line D to form a flat surface 94 to improve the adhesion of the masking jig, which has been conventionally used. In this case, since the flat surface 94 is transparent and the lamp or the inside of the vehicle body is seen through, the design feels uncomfortable, and it has been a problem to solve these points.

[0005]

[Means for Solving the Problems] As a concrete means for solving the above-mentioned conventional problems, the present invention comprises a knurl on the inner surface of a flange portion of a lens for preventing see-through inside the lamp. In the lens of a vehicle lamp, at least a part of the knurl is a simple knurling in which the pitch of the knurl is divided into two, one of which is a textured surface and the other of which is a transparent surface. The problem is solved by providing a lens for a lamp.

【Example】

 Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a lens of a vehicular lamp according to the present invention. A flange 2 is provided on the peripheral edge of the lens 1, and the flange 2 is provided with a knurl 3 from the rear side. Similar to the conventional example, a part where the knurling 3 cannot be applied is generated due to the condition that the coating film 5 is applied to a part thereof.

Here, in the present invention, the simple knurling 4 is provided for the above-mentioned part where the knurling 3 cannot be applied, but the part where the knurling 3 cannot be applied for easy understanding. As in the case of the conventional example, description will be made assuming the vicinity of the boundary line D with the coating film 5.

Next, the structure of the simple knurling 4 will be described in detail. The simple knurling 4 is configured such that one unit is equivalent to the pitch P of the knurling 3, and the above-mentioned one unit. Is to divide the pitch P into two substantially equal parts, and to form a fine uneven surface on one side thereof to form the embossed surface 4a, and to make the other surface a transparent surface 4b which remains transparent. After the simple knurling 4 is applied, the flange 2 has the textured surface 4a and the transparent surface 4b having a width half the pitch P alternately arranged.

Next, the operation and effect of the lens 1 of the present invention having the above-described structure will be described. First, in the portion of the flange 2 where the knurls 3 are applied, the interior of the vehicle lamp is affected by the lens operation or the like. It is exactly the same as the conventional example that it prevents see-through.

In the portion of the simple knurl 4, the textured surface 4a of the simple knurl 4 reflects external light in a diffused state, and the transparent surface 4b on one side transmits and reflects the external light. There will be nothing. A state in which half of the pitch P is reflected and the other half is transmitted is very similar to a state in which the portion of the flange 2 provided with the knurls 3 is viewed from the outside of the lens 1.

Therefore, the portion where the simple knurling 4 is performed is viewed as if the knurling 3 is applied, and thus the flange 2 is knurled 3 up to the boundary line D with the coating film 5. It will be viewed like this, and it will prevent the discomfort that has occurred in the appearance.

At this time, the simple knurling 4 is composed of a textured surface 4 a and a transparent surface 4 b, and each of them is flat, so that the masking jig for forming the coating film 5 is formed. Therefore, the boundary line D can be formed as a clear and beautiful one without wraparound.

[0013]

[Effect of device]

 As described above, according to the present invention, at least a part of the knurl is a lens which is formed by dividing the pitch of the knurl into two parts, one of which is a textured surface and the other of which is a transparent surface. The easy knurling that is formed as a flat surface makes it possible to perform coating without impairing the adhesion of the masking jig even when it is necessary to provide a coating film on a part of the flange. It is possible to form a field line and to prevent discomfort by allowing the simple knurling to look as if the knurling is continuous, and for vehicles that use this type of lens. It is extremely effective in improving the aesthetics of the lamp.
