Abstract
Description
図1に示すように、本発明の第1実施形態に係るドアライニング12(取付対象)は、例えば、プラスチック等の樹脂材料で構成されており、車両(自動車)のドアパネルの内側に取り付けられる。なお、以下の説明では、ドアライニング12の車両前方をX1方向、車両後方をX2方向、車幅方向外側をY1方向、車幅方向内側をY2方向、鉛直下方をZ1方向、鉛直上方をZ2方向と呼ぶことがある。
[本実施形態の概略構成]
本発明の第2実施形態に係る照明装置310の取付構造312は、例えば、図10~図16に示すように、車両のドアパネルの車室内側に取り付けられるドアライニング314に適用される。ただし、取付構造312は、この一実施形態に限定されるものではなく、ドアライニング314以外の車両の内装部材や、該内装部材以外の物体を取付対象として、該取付対象に照明装置310を取り付けることも可能である。以下の説明では、照明装置310が取付構造312を介して車両のリアドアのドアライニング314に取り付けられる場合について説明する。
ここで、本実施形態に係る取付構造312及び照明装置310の具体的な構成について、図17~図22を参照しながら説明する。なお、この説明では、必要に応じて、図10~図16も参照しながら説明する。また、図17~図22に示す矢印A方向、矢印B方向及び矢印C方向は、取付構造312と照明装置310との位置関係を明確にするために図示した3軸方向であり、ドアライニング314に対する取付構造312及び照明装置310の配置箇所によっては、図10~図16に示す矢印X方向、矢印Y方向及び矢印Z方向の3軸方向とは対応しない場合がある。
本実施形態に係る照明装置310の取付構造312は、以上の通りである。次に、照明装置310を取付構造312に取り付ける際の取付手順と、取り付け後の照明装置310から飲料容器330への照明光340の照射とについて説明する。
本実施形態は、上記の説明に限定されることはなく、種々の変更が可能であることは勿論である。
本実施形態に係る照明装置310の取付構造312は、例えば、図24に示す金型装置454を用いて、アッパー部316と一体的に形成することができる。
以上説明したように、本実施形態に係る照明装置310の取付構造312によれば、取付構造312の筐体支持部434は、筐体350の段差部378の形状に合わせた段差部436を備えている。そのため、取付構造312に照明装置310が挿入された場合、段差部436は、筐体350の段差部378に対する受け部として機能する。すなわち、段差部436が段差部378に応じた形状であるため、筐体350を取付構造312に挿入して、段差部378が段差部436に突き当たると、該段差部436は、段差部378に対する台座として機能する。これにより、筐体350の段差部378を段差部436で容易に支持することが可能となり、照明装置310を安定に支持することができる。
ところで、例えば、特許第4933240号公報には、車両のドアライニングにねじを用いて照明装置の一端部を固定すると共に、該ドアライニングに設けられた係合片を用いて照明装置の他端部を支持することで、ドアライニングに照明装置を取り付けることが開示されている。
