【産業上の利用分野】[Industrial applications]

本考案は車両用灯具のレンズに係り、特に、前側らか見たときレンズ脚が外見 に現われないように改良した車両用灯具のレンズに関するものである。ただし、 本考案において前側とは、当該灯具の投光方向の側をいい、車両の進行方向とは 関係が無い。 The present invention relates to a lens for a vehicular lamp, and more particularly to a lens for a vehicular lamp improved so that the lens legs do not appear when viewed from the front. However, in the present invention, the front side refers to the side of the lighting direction of the lamp and has no relation to the traveling direction of the vehicle.

【従来の技術】[Prior Art]

図2は車両用灯具の1例を示す部分的断面図であって、ランプハウジング1の 前方開口部を覆う形にレンズ2が装着されている。その装着構造として、ランプ ハウジング1の周囲にシール溝1aが形成されるとともに、レンズ2の背面側に レンズ脚2aが一体的に成形されている。そして、上記レンズ脚2aはシール溝 1aに挿入され、熱軟化性接着剤であるホットメルト3によって接着されている 。2bはレンズ2の背面側に一体成形されたプリズムである。前記ランプハウジ ングの後側中央部にソケット6が取り付けられて、光源バルブ7を支持している 。 FIG. 2 is a partial sectional view showing an example of a vehicular lamp, in which a lens 2 is mounted so as to cover the front opening of the lamp housing 1. As a mounting structure, a seal groove 1a is formed around the lamp housing 1, and a lens leg 2a is integrally formed on the back side of the lens 2. The lens leg 2a is inserted into the seal groove 1a and adhered by the hot melt 3 which is a thermosoftening adhesive. Reference numeral 2b is a prism integrally formed on the back side of the lens 2. A socket 6 is attached to the rear center of the lamp housing to support a light source bulb 7.

【考案が解決しようとする課題】[Problems to be solved by the device]

上記レンズ2の、レンズ脚2a付近の斜視図を図3(A)に示す。このレンズ は一般に合成樹脂材料で射出成形され、無色,赤色,橙色,アンバー色など各種 の色調のものが有るが、いずれも透明である。従って、これを矢印Eyeのごと く前側から見ると、斑点を付して示したように透明なレンズ脚2aの影2cが視 認される。 このレンズ2の正面図を図3(B)に示す。レンズの周辺部に上記レンズ脚の 影2cが現われ、商品価値を低下させる。上記と異なる問題点として、前記のレ ンズ脚の根本付近は肉厚になるので、これを合成樹脂材料で射出成形する場合、 脚に対向するレンズ前面側にヒケを生じる。 本考案は上述の事情に鑑みて為されたもので、透明なレンズ脚の影が外見に現 われず、しかもレンズ前面側がレンズ脚に対向している個所にヒケを生じるおそ れの無い、車両用灯具のレンズを提供することを目的とする。 A perspective view of the lens 2 near the lens leg 2a is shown in FIG. This lens is generally injection-molded from synthetic resin material and is available in various color tones such as colorless, red, orange, and amber, but they are all transparent. Therefore, when this is viewed from the front side as indicated by the arrow Eye, the shadow 2c of the transparent lens leg 2a is visible as shown by the spots. A front view of this lens 2 is shown in FIG. The shadow 2c of the lens leg appears on the peripheral portion of the lens, which lowers the commercial value. As a problem different from the above, since the vicinity of the root of the lens leg is thick, when this is injection-molded with a synthetic resin material, a sink mark occurs on the lens front surface side facing the leg. The present invention has been made in view of the above circumstances, and a vehicle in which a shadow of a transparent lens leg does not appear in the appearance and a sink mark is not generated in a portion where the front surface of the lens faces the lens leg. An object is to provide a lens for a lighting fixture.

【課題を解決するための手段】[Means for Solving the Problems]

上記の目的を達成するために創作した本考案の基本的原理は、前面レンズの板 状部の脚付近を2層構造とし、多色成形スキン成形法によって上記2層の何れか 片方を不透明とする。上述の原理に基づく具体的構成として、第1の考案の車両 用灯具のレンズは、ランプハウジングのシール溝に挿入してシール剤によって接 着される脚を一体的に成形した合成樹脂製の車両用灯具のレンズにおいて、 不透明な合成樹脂で構成されたレンズ脚部分と、上記レンズ脚部分に対して多 色成形法を用いて一体的にスキン成形された透明なレンズ本体部分とよりなるこ とを特徴とする。 The basic principle of the present invention, which was created to achieve the above object, is that the vicinity of the leg of the plate-shaped portion of the front lens has a two-layer structure, and one of the two layers is made opaque by the multicolor molding skin molding method. To do. As a specific configuration based on the above-mentioned principle, the lens of the vehicle lamp of the first invention is a vehicle made of synthetic resin in which the legs to be inserted into the seal groove of the lamp housing and joined by the sealant are integrally formed. The lens of the lighting device comprises a lens leg portion made of an opaque synthetic resin and a transparent lens body portion integrally skin-molded on the lens leg portion by a multicolor molding method. Is characterized by.

【0005】 また第2の考案は、ランプハウジングのシール溝に挿入してシール剤によって 接着される脚を一体的に成形した合成樹脂製の車両用灯具のレンズにおいて、 レンズ脚を一体成形された透明な合成樹脂製のレンズ本体と、上記レンズ本体 のレンズ脚部分の前側に位置せしめて、該レンズ脚を覆う形の不透明なスキン層 とよりなることを特徴とする。A second invention is a lens of a synthetic resin vehicle lamp in which a leg which is inserted into a seal groove of a lamp housing and adhered by a sealant is integrally molded, and the lens leg is integrally molded. It is characterized by comprising a lens body made of a transparent synthetic resin and an opaque skin layer which is located in front of the lens leg portion of the lens body and covers the lens leg.

【0006】[0006]

【作用】[Action]

上記の構成によれば、レンズ脚付近が2層構造になっていて、前面側の層はレ ンズ脚を含んでいないので肉厚とならず、従ってヒケを生じるおそれが無い。 さらに、上記2層の何れか一方が不透明になっているので、透明なレンズ板状 部を通して透明な脚の影が見えるという不具合は無くなる。 According to the above configuration, the vicinity of the lens leg has a two-layer structure, and the layer on the front side does not include the lens leg, so that it is not thick, and therefore there is no risk of sink marks. Further, since either one of the above two layers is opaque, the problem that the shadow of the transparent leg can be seen through the transparent lens plate portion is eliminated.

【実施例】【Example】

図1(A)は前記第1の考案の1実施例を示す断面図である。この実施例の前 面レンズ4は、レンズ脚の根本付近の区域aが2層構造になっている。すなわち 、4aは赤色で不透明な合成樹脂材料を用いて射出成形された不透明な脚である 。上記の不透明脚を成形用金型内にセットして、アンバー色で透明な合成樹脂材 料により、多色成形法によってレンズ本体4bがスキン成形されている。4cは 、上記レンズ本体4bの背面側に一体成形されたプリズムである。上記レンズ本 体4bの区域aは、不透明な脚4aと異なる時点に成形されるので、脚の影響を 受けてヒケを生じるおそれが無い。また、これを矢印b方向に見たとき、図3( B)について前述したような、透明な脚の影は外見に現われない。 図1(B)は前記第2の考案の1実施例を示す断面図である。レンズ脚5aの 前面側(図において左側)を覆う形の、厚さ寸法t1=2.5mmの不透明スキン 5dを取り除いた形状のレンズ本体5cが、透明な合成樹脂材料により、レンズ 脚5aを含めて射出成形されている。図示の厚さ寸法t2は2mmである。このレ ンズ本体5cに対して、不透明な合成樹脂材料にによって不透明スキン5dがス キン成形されている。 レンズ本体5cの、レンズ脚付近にヒケを生じても前記不透明スキン5dで埋 められてヒケが消失する。該不透明スキン5dは厚さ寸法t1=2.5mmであり 、レンズ脚5aと別個に成形されるから該不透明スキン5dの前面にヒケを生じ るおそれは無い。また、レンズ脚5aは不透明スキン5dで覆われているので外 見に現われない。FIG. 1A is a sectional view showing an embodiment of the first invention. The front lens 4 of this embodiment has a two-layer structure in the area a near the base of the lens leg. That is, 4a is an opaque leg injection-molded using a red and opaque synthetic resin material. The opaque legs are set in a molding die, and the lens body 4b is skin-molded by a multicolor molding method using an amber-colored transparent synthetic resin material. Reference numeral 4c is a prism integrally formed on the back side of the lens body 4b. The area a of the lens body 4b is molded at a time different from that of the opaque leg 4a, so there is no possibility of sinking under the influence of the leg. Also, when this is viewed in the direction of arrow b, the shadow of the transparent leg as described above with reference to FIG. 3B does not appear in the appearance. FIG. 1B is a sectional view showing an embodiment of the second invention. The lens body 5c, which covers the front side (left side in the figure) of the lens leg 5a and is formed by removing the opaque skin 5d having a thickness t 1 = 2.5 mm, is made of a transparent synthetic resin material to cover the lens leg 5a. It is injection molded including. The illustrated thickness dimension t 2 is 2 mm. An opaque skin 5d made of an opaque synthetic resin material is skin-molded on the lens body 5c. Even if a sink mark occurs near the lens leg of the lens body 5c, the sink mark disappears because it is filled with the opaque skin 5d. The opaque skin 5d has a thickness t 1 = 2.5 mm and is molded separately from the lens legs 5a, so there is no risk of sink marks on the front surface of the opaque skin 5d. Further, the lens leg 5a is covered with the opaque skin 5d and therefore does not appear to the outside.

【考案の効果】[Effect of the device]

以上に説明したように、本考案の車両用灯具のレンズを適用すると、レンズ脚 根本部分が肉厚であるためにヒケを生じることを防止し、ないしヒケの害を解消 し、かつ、透明なレンズ脚の影が外見に現われて商品価値を低下させるおそれが 無い。 As described above, when the lens of the vehicular lamp of the present invention is applied, it is possible to prevent sink marks from occurring due to the thick part of the lens legs, and to eliminate the damage of the sink marks and to make them transparent. There is no risk that the shadow of the lens leg will appear in the appearance and reduce the product value.
