【考案の詳細な説明】 〔産業上の利用分野〕 本考案は反射鏡に関し、特に、車両の走行の安全性を図
るために道路等に設置される道路反射鏡として用いるの
に好適な反射鏡に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a reflector, and particularly to a reflector that is suitable for use as a road reflector installed on a road or the like in order to ensure the safety of traveling of a vehicle. Regarding
従来から道路等の曲がり角には、車両の走行の安全を図
るために反射鏡が設置されている。Conventionally, a reflector is installed at a corner of a road or the like to ensure the safety of running of a vehicle.
ところが、この反射鏡は、外気温の変化によって鏡面が
結露し鏡面のくもりによって反射鏡としての機能が低下
する。However, the function of the reflecting mirror deteriorates due to dew condensation on the mirror surface due to changes in the outside temperature and clouding of the mirror surface.
このため、反射鏡の鏡体内部にヒータを埋設したり、地
下水を導いて鏡体を加熱したりするものが提案されてい
る。For this reason, there has been proposed one in which a heater is embedded inside the mirror body of the reflecting mirror or one in which ground water is guided to heat the mirror body.
しかし、これらの構成では工事費が高くなったり、設置
場所が限られたりするという不具合がある。However, these configurations have drawbacks such as high construction cost and limited installation location.
そこで、鏡体の鏡面部の裏面側に蓄熱材を貼着して鏡体
を加熱するようにしたものが提案されている。Therefore, there has been proposed a device in which a heat storage material is attached to the back surface side of the mirror surface portion of the mirror body to heat the mirror body.
このような構成を採用すれば、工事費の低減を図ること
ができるとともに、設置場所に制限されることはない。If such a configuration is adopted, the construction cost can be reduced and the installation location is not limited.
しかしながら、従来技術では、蓄熱材を鏡体の鏡面部の
裏面側に貼着させているため、外気温が融点よりも低い
温度から融点より高い温度へ上昇すると蓄熱材が吸熱す
るが、このときに鏡体の鏡面が外気温よりも低くなり、
鏡面が結露して鏡面がくもることがある。However, in the prior art, since the heat storage material is attached to the rear surface side of the mirror surface portion of the mirror body, when the outside air temperature rises from a temperature lower than the melting point to a temperature higher than the melting point, the heat storage material absorbs heat. In addition, the mirror surface of the mirror body becomes lower than the outside temperature,
Condensation on the mirror surface may cause the mirror surface to become cloudy.
本考案の目的は、外気温の変化によっても鏡面が結露す
るのを防止することができる反射鏡を提供することにあ
る。An object of the present invention is to provide a reflecting mirror capable of preventing dew condensation on the mirror surface even when the ambient temperature changes.
前記の目的を達成するために本考案は、鏡面部を有する
鏡体と、前記鏡面部の裏面側に設けられる押え板との間
で空間部を形成し、該空間部内に、液体から固体に又は
固体から液体に相変化するとともに、相変化時に体積変
化する潜熱型の蓄熱材を設け、該蓄熱材の押え板側の面
を押え板側に固着させた手段を採用したものである。In order to achieve the above-mentioned object, the present invention forms a space between a mirror body having a mirror surface portion and a holding plate provided on the back side of the mirror surface portion, and from the liquid to the solid in the space portion. Alternatively, a means is provided in which a latent heat type heat storage material that changes in phase from solid to liquid and changes in volume during phase change is provided, and the surface of the heat storage material on the side of the holding plate is fixed to the side of the holding plate.
本考案は上記の手段を採用したことにより、外気温の変
化によって蓄熱材が固体から液体に相変化するときには
潜熱を吸熱するが、蓄熱材と鏡面部の裏面側との間には
空隙が形成されるため、外気温が融点よりも低い温度か
ら融点よりも高い温度へ上昇しても鏡面温度を外気温と
同じに維持することができ、鏡面が結露するのを防止す
ることが可能となる。By adopting the above means, the present invention absorbs latent heat when the heat storage material undergoes a phase change from a solid to a liquid due to a change in outside air temperature, but a gap is formed between the heat storage material and the rear surface side of the mirror surface portion. Therefore, even if the outside air temperature rises from a temperature lower than the melting point to a temperature higher than the melting point, the mirror surface temperature can be kept the same as the outside air temperature, and it is possible to prevent dew condensation on the mirror surface. .
以下、本考案の一実施例を図面に基づいて説明する。 An embodiment of the present invention will be described below with reference to the drawings.

前記押え板15は円板状に形成され、中央部の断面が円弧
状となるように形成されている。The holding plate 15 is formed in a disc shape, and is formed such that the cross section of the central portion is an arc shape.
そして、前記押え板15の外周側端部が裏板12の前面側に
固着されている。The outer peripheral end of the pressing plate 15 is fixed to the front side of the back plate 12.
鏡体16は裏板12と同じ大きさで円板状に形成されてお

前記蓄熱材19としては、０〜10℃の融点を持つ蓄熱材、
例えば有機系材料であれば融点が４〜８℃、潜熱36cal/
g、粘度6.0〜8.0のポリエチレングリコールが用いられ

For example, if it is an organic material, the melting point is 4-8 ° C, the latent heat is 36 cal /
g, polyethylene glycol having a viscosity of 6.0 to 8.0 is used.
そして、蓄熱材19は、液相時には、その密度減少により

に、第２図に示されるように、鏡体16の鏡面部17の裏面
側との間に空隙21を形成する状態で挿入されている。Then, the heat storage material 19 is in close contact with the back surface side of the mirror surface portion 17 of the mirror body 16 in the liquid phase because the volume expands due to the decrease in the density, and when the solid phase, the volume decreases due to the increase in the density. As shown in FIG. 2, the mirror body 16 is inserted with a gap 21 formed between the mirror surface portion 17 and the back surface side.

裏面側と密着し、良好な放熱状態を保つことができる。In the above configuration, when the outside air temperature is a temperature at which the heat storage material 19 is in a liquid phase state, the heat storage material 19 expands in volume and adheres to the back surface side of the mirror surface portion 17, so that a good heat radiation state can be maintained.
このため外気温が融点よりも高い温度から融点よりも低
い温度へ低下しても蓄熱材19から潜熱が放熱されるので
鏡面部17の表面に結露が生じるのを防止することができ

面表面に結露が生じるようなこともない。According to the present invention, a space is formed between a mirror body having a mirror surface portion and a holding plate provided on the back side of the mirror surface portion, and a phase is changed from liquid to solid or solid to liquid in the space portion. Along with this, a latent heat type heat storage material that changes in volume during a phase change is provided, and the holding plate side surface of the heat storage material is fixed to the holding plate side, so that, for example, when the phase changes from liquid to solid. By using a type of heat storage material that releases latent heat and absorbs latent heat when it changes from solid to liquid, if the volume of the heat storage material is reduced when it is in the solid phase, Since the surface is fixed to the holding plate side, a gap is formed between the surface of the heat storage material in the free state on the mirror surface side and the back side of the mirror surface, and the surface of the mirror surface portion is formed by this space. The temperature can be kept at the same temperature as the outside temperature. Therefore, even if the heat storage material absorbs latent heat, the surface temperature of the mirror surface portion does not become lower than the outside air temperature, and dew condensation does not occur on the mirror surface.

れることにより鏡面に結露が生じるようなことはない。On the other hand, when the volume expands when the heat storage material is in the liquid state, the surface of the heat storage material on the mirror surface side is in a free state. The void formed between and disappears, and the entire surface of the heat storage material on the mirror surface side contacts the back surface side of the mirror surface section. Therefore, even if the outside air temperature decreases from a temperature higher than the melting point of the heat storage material to a lower temperature, dew condensation does not occur on the mirror surface due to the release of latent heat from the heat storage material to the mirror surface portion.
したがって、外気温の変化に影響されることなく鏡面部
