Abstract

<P>PROBLEM TO BE SOLVED: To provide a mirror, projecting a normal mirror image and an enlarged mirror image using one mirror, light-weighted and securing the safety in carrying. <P>SOLUTION: This mirror is characterized in that the surface thereof partially uses a plastic flat plate machined to have a Fresnel lens structure as a base material. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、一枚の鏡で通常の鏡像と、拡大された鏡像を映すことのできる鏡に関するものである。The present invention relates to a mirror capable of projecting a normal mirror image and an enlarged mirror image with a single mirror.

外出中に化粧したり、化粧直ししたりするために、比較的大型のガラス製の平面鏡を携帯している女性が多い。しかし、大型のガラス製鏡は重く、破損のおそれもある。
また、拡大鏡は皮膚の細部の観察、コンタクトレンズの着装などに便利なため、携帯したいものであるが、通常市販されているものはガラス製で二枚組のものである。この場合安全上の問題点は変わらず、重量はさらに重くなり携帯に不便である。
特開２００４−３２１５６５号公報 Many women carry a relatively large glass plane mirror to make up or remake while on the go. However, large glass mirrors are heavy and can be damaged.
In addition, the magnifying glass is convenient for observing the details of the skin, wearing contact lenses, and the like, so it is desirable to carry it, but what is usually marketed is a glass-made two-piece set. In this case, the safety problem does not change, and the weight is further increased, which is inconvenient to carry.

本発明が解決しようとする課題は、上述のような問題を解決した、軽量でかつ携帯時の安全性を確保した鏡を提供することにある。  The problem to be solved by the present invention is to provide a mirror that solves the above-described problems and that is lightweight and secures safety when carried.

問題を解決するための手段Means to solve the problem

本発明者は、上記課題に鑑み鋭意検討した結果、特定の構造と構成を採用すれば、上記課題を容易に解決できることを見出し、本発明を完成するに至った。
すなわち、本発明の要旨は、鏡を作成するにあたり、表面の一部がフレネルレンズ構造に加工されたプラスチックの平板を基材とすることを特徴とすることある。As a result of intensive studies in view of the above problems, the present inventors have found that the above problems can be easily solved by adopting a specific structure and configuration, and have completed the present invention.
That is, the gist of the present invention is characterized in that, in producing a mirror, a plastic flat plate whose surface is partially processed into a Fresnel lens structure is used as a base material.

発明の効果The invention's effect

本発明によれば、軽量でかつ携帯時の安全性を確保した鏡を提供することができ、本発明の工業的価値は高い。  ADVANTAGE OF THE INVENTION According to this invention, the mirror which was lightweight and ensured the safety at the time of carrying can be provided, and the industrial value of this invention is high.

以下、本発明を具体的に説明する。
本発明における、鏡の基材となるプラスチック素材としては、例えばアクリル樹脂、ポリカーボネート樹脂、サイクリックポリオレフィンなどの透明樹脂があげられる。The present invention will be specifically described below.
In the present invention, examples of the plastic material serving as the mirror substrate include transparent resins such as acrylic resin, polycarbonate resin, and cyclic polyolefin.

本発明における鏡の基材となるプラスチックの平板は、その平面の一部がフレネルレンズ型に加工されていることに特徴を有するものであるが、その作成には、プレス用金型を用いて、プラスチック平板を該金型で熱プレスすることにより、あるいは射出成型用の金型を用いて、樹脂を射出成型することによって作成しても良いが、プレス成型による方が、金型に、より忠実な成型物を得ることが可能であり、得られた成型物の歪の少なさに起因する、映像の鮮明さなどの点で好ましい。
得られた成型物の裏面に、例えばアルミニュウム等の金属を蒸着加工あるいは鍍金加工等を施すことによって、拡大鏡の部分を有する鏡をうることができる。さらに、鏡の表面には、ハードコート層を設けて、擦り傷などを防ぎ、鏡の明度の劣化を抑制することができる。また実用上は、該鏡の裏面に補強用の平板、周囲には縁などをつけて製品とされる。The plastic flat plate used as the base material of the mirror in the present invention is characterized in that a part of the flat surface is processed into a Fresnel lens mold. In addition, it may be created by hot pressing a plastic flat plate with the mold, or by injection molding a resin using a mold for injection molding. It is possible to obtain a faithful molded product, which is preferable in terms of the clearness of the image due to the small distortion of the obtained molded product.
A mirror having a magnifying glass portion can be obtained by subjecting the back surface of the obtained molding to vapor deposition or plating of a metal such as aluminum. Furthermore, a hard coat layer can be provided on the surface of the mirror to prevent scratches and the like and to suppress deterioration of the brightness of the mirror. In practical use, a reinforcing flat plate is provided on the back surface of the mirror, and an edge or the like is attached to the periphery to provide a product.

図１は、本発明の一例を示す概略説明図であり、鏡の平面図である。１で示した部分が鏡の平面部であり、２で示した部分がその裏面がフレネルレンズの構造を形成している部分であり、拡大像が写る部分である。この図においては、フレネルレンズ構造部分は模式的に表現されている。
図２は鏡の断面図であり、１が鏡の平面部であり、２が、フレネルレンズ構造部分である。該部分の形状は模式的に表現されているが、その裏面の表面が金属の蒸着などにより金属薄膜層３が形成され、凹面鏡の機能を、したがって像を拡大する機能を有する。平面部分は、フレネルレンズ構造部分と同様に金属の蒸着などにより金属薄膜層３に覆われて通常の鏡として機能する。４は金属層表面の保護のための塗装層である。FIG. 1 is a schematic explanatory view showing an example of the present invention, and is a plan view of a mirror. The portion indicated by 1 is the flat portion of the mirror, the portion indicated by 2 is the portion where the back surface forms the structure of the Fresnel lens, and is the portion where the magnified image appears. In this figure, the Fresnel lens structure portion is schematically represented.
FIG. 2 is a cross-sectional view of the mirror, in which 1 is a plane portion of the mirror and 2 is a Fresnel lens structure portion. Although the shape of the portion is schematically represented, the metal thin film layer 3 is formed on the surface of the back surface thereof by vapor deposition of metal or the like, and has the function of a concave mirror and thus the function of enlarging the image. The plane portion is covered with the metal thin film layer 3 by metal deposition or the like, like the Fresnel lens structure portion, and functions as a normal mirror. Reference numeral 4 denotes a coating layer for protecting the metal layer surface.

本発明は、軽量でかつ携帯時の安全性を確保した鏡として、主として女性の外出時の化粧鏡としてのみならず、近くのものが見えにくくなった中高年男性の旅行時使用する髭剃り鏡として利用することができる。  The present invention is a lightweight mirror that ensures safety when carrying, not only as a makeup mirror when going out for women, but also as a shaving mirror used when traveling by middle-aged and elderly men who have become difficult to see nearby objects. Can be used.
