Description

【０００１】
【発明の属する技術分野】
本発明は、載置される物品の形状に応じて凸部や凹部が形成されている、一対のダネッジからなるダネッジシステムに関するものである。
【０００２】
【従来の技術】
先ず最初に、従来のダネッジ及び本発明のダネッジシステムに載置される一例としての物品について、図１０及び図１１を用いて説明する。
【０００３】
物品Ａは、円筒状の台座部ａ１と、円筒状の台座部ａ１の内周面ａ１ａに沿って立設された円筒状の頭部ａ２とを有しており、円筒状の頭部ａ２の天板ａ２ａには、その中央に、透孔ａ２ｂが穿設されている。
【０００４】
上述したような物品Ａを載置可能な従来の同一構成を有するダネッジ１００は、平板部１０１と、平板部１０１に複数形成された、物品Ａの円筒状の台座部ａ１内に嵌合可能な、天板１０２ａを有する円筒部１０２から構成されている。
【０００５】
図１２に示されているように、下に位置するダネッジ１００の円筒部１０２を、物品Ａの円筒状の台座部ａ１内を嵌合した後、下に位置するダネッジ１００に載置された物品Ａの頭部ａ２の天板ａ２ａに、上に位置するダネッジ１００の平板部１０１を載置することになる。
【０００６】
【発明が解決しようとする課題】
上述した従来のダネッジ１００の場合には、下に位置する物品Ａの頭部ａ２の天板ａ２ａの外周縁部と、上に位置する物品Ａの台座部ａ１の底面ａ１ｂの内周縁部とが、ダネッジ１００を介して対峙するように段積みされており、従って、下に位置する物品Ａと上に位置する物品Ａとが対峙している面積が小さいので、ダネッジ１００の寸法ばらつき、特に、円筒部１０２の寸法ばらつきにより、下に位置する物品Ａと上に位置する物品Ａとの位置が、水平方向にずれたりすると、上に位置する物品Ａの台座部ａ１の底面ａ１ｂが、下に位置する物品Ａの頭部ａ２の天板ａ２ａから外れて、上に位置する物品Ａが、下に位置する物品Ａに、ダネッジ１００を介して載置されずに、ダネッジ１００に、直に、載置されることがある。このように、上に位置する物品Ａが、下に位置する物品Ａに、ダネッジ１００を介して載置されずに、ダネッジ１００に、直に、載置されると、安定した状態で、物品Ａが載置されたダネッジ１００を、多段に段積みすることができないという問題があった。また、上に位置する物品Ａが、ダネッジ１００に、直に、載置されると、薄肉のダネッジ１００が損傷するという問題があった。
【０００７】
本発明の目的は、上述したような従来のダネッジが有する課題を解決することにある。
【０００８】
【課題を解決するための手段】
本発明は、上述した目的を達成するために、第１には、第１ダネッジの上部嵌合部材を、正常状態の物品の柱状空間に嵌合するようにして、第１ダネッジに物品を載置した後、第２ダネッジの凸状支持部材内に、下に位置する第１ダネッジに正常状態で載置された物品を嵌合するとともに、第２ダネッジの凸状支持部材の環状天板を、下に位置する第１ダネッジに正常状態に載置された物品の頭部に載置し、次いで、逆さ状態の物品の頭部の天板に穿設された透孔に、第２ダネッジの凸状支持部材の嵌合筒部を嵌合するとともに、第２ダネッジの環状天板に、逆さ状態の物品の頭部の天板を載置するようにダネッジシステムを構成したものであり、第２には、第１ダネッジの上部嵌合部材を、正常状態の物品の柱状空間に嵌合するようにして、第１ダネッジに物品を載置した後、第２ダネッジの凸状支持部材内に、下に位置する第１ダネッジに正常状態で載置された物品を嵌合するとともに、第２ダネッジの凸状支持部材の環状天板を、下に位置する第１ダネッジに正常状態に載置された物品の頭部に載置し、次いで、逆さ状態の物品の頭部の天板に穿設された透孔に、第２ダネッジの凸状支持部材の嵌合筒部を嵌合するとともに、第２ダネッジの環状天板に、逆さ状態の物品の頭部の天板を載置し、更には、もう１つの第１ダネッジの下部嵌合部材を、下に位置する第２ダネッジに逆さ状態で載置された物品の柱状空間に嵌合した後、上記のもう１つの第１ダネッジの上部嵌合部材に、正常に配置された物品の柱状空間を嵌合するようにダネッジシステムを構成したものである。
【０００９】
【実施例】
以下に、本発明の実施例について説明するが、本発明の趣旨を越えない限り何ら、本実施例に限定されるものではない。
【００１０】
本発明のダネッジシステムは、上述した台座部ａ１と頭部ａ２とからなる物品Ａの台座部ａ１が載置される第１ダネッジＤ１と、物品Ａの頭部ａ２が載置される第２ダネッジＤ２との一対のダネッジＤ１、Ｄ２とから構成されている。
【００１１】
先ず最初に、図１〜図６を用いて、第１ダネッジＤ１について説明する。
【００１２】
平面形状が略方形状に第１ダネッジＤ１は、平板部１と、平板部１を上方に膨出させることにより形成された上部嵌合部材２と、平板部１を下方に膨出させることにより形成された下部嵌合部材３とを有している。
【００１３】
上部嵌合部材２は、中心点ｃ１を有する仮想円Ｃ１に沿った外周面２ａ１を有する、複数個の嵌合凸部２ａから構成されており、嵌合凸部２ａは、平板部１を上方に膨出させることにより形成されている。本実施例においては、上部嵌合部材２は、３個の嵌合凸部２ａから構成されており、各嵌合凸部２ａは、平面的に見て、１２０度ずつ、ずれて形成されている。嵌合凸部２ａの外周面２ａ１の略中央部には、縦溝２ｂが形成されており、嵌合凸部２ａの外周面２ａ１を面変化させることにより、嵌合凸部２ａの強度を高めるように構成されている。
【００１４】
上部嵌合部材２を構成する嵌合凸部２ａ間に位置する平板部１を、下方に膨出させることにより、裏面形状が、略Ｙ字状の下部嵌合部材３が形成されている。下部嵌合部材３の中心点ｃ２と上部嵌合部材２の中心点ｃ１とは、平面的に見て、一致しており、また、下部嵌合部材３の３個の先端垂直面３ｂにより形成される、中心点ｃ２を中心とした仮想円は、上部嵌合部材２の中心点ｃ１を中心とした仮想円Ｃ１と、ほぼ同じ径を有している。
【００１５】
第１ダネッジＤ１の平板部１には、上述した上部嵌合部材２及び下部嵌合部材３が、複数個、形成されている。本実施例においては、それぞれ、１２個の上部嵌合部材２及び下部嵌合部材３が形成されている。上部嵌合部材２及び下部嵌合部材３は、物品Ａの円筒状の台座部ａ１の内周面ａ１ａ及び円筒状の頭部ａ２の内周面ａ２ｃにより形成される円柱状空間ａ３に嵌合するように構成されている。
【００１６】
４は、上部嵌合部材２の周囲に形成された、平板部１を上方に膨出させることにより形成された、上部嵌合部材２より低い適当数の凸部であり、５は、同じく、平板部１を上方に膨出させることにより形成された、平板部１の相対する辺１ａに沿って形成された上部嵌合部材２より低い適当数の凸部である。このような、凸部４、５を形成させて、平板部１を面変化させることにより、平板部１の強度や曲げ剛性を上げることができる。なお、１ｂは、平板部１の周囲を囲むように形成された垂直壁である。
【００１７】
次に、図７〜図８を用いて、第２ダネッジＤ２について説明する。
【００１８】
第２ダネッジＤ２は、第１ダネッジＤ１と同じ大きさに形成されており、第２ダネッジＤ２には、平板部６の上面に立設された台座円筒部７ａと、台座円筒部７ａの上端に形成された環状天板７ｂと、環状天板７ｂの内周縁から上方に延在する嵌合円筒部７ｃと、円板状天板７ｄとからなる凸状支持部材７が形成されている。凸状支持部材７は、第１ダネッジＤ１の平板部１に形成された上部嵌合部材２及び下部嵌合部材３に対応するように配置されている。即ち、第１ダネッジＤ１と第２ダネッジＤ２とを、上下方向に重なるように配置した際に、平面的に見て、第１ダネッジＤ１に形成された上部嵌合部材２及び下部嵌合部材３と、第２ダネッジＤ２に形成された凸状支持部材７が、一致するように構成されている。
【００１９】
８は、平板部６の周囲に形成された土手部であり、９は、土手部８の周縁に沿って形成された垂直壁である。また、１０は、第２ダネッジＤ２に形成された凸状支持部材７の台座円筒部７ａ同士、及び、凸状支持部材７の台座円筒部７ａと土手部８を連結するように配置された直線状の凹溝である。このような土手部８や凹溝１０を、適宜、形成することにより、第２ダネッジＤ２の強度や曲げ剛性を高めることができる。
【００２０】
次に、上述した第１ダネッジＤ１と第２ダネッジＤ２を用いて、上述した物品Ａを段積み状態に載置する段積み方法について説明する。
【００２１】
先ず最初に、図１や図２や図９等に示されているように、台座部ａ１が下で、頭部ａ２が上に位置するように、正常状態に物品Ａを配置した後、第１ダネッジＤ１の上部嵌合部材２を、正常状態の物品Ａの円柱状空間ａ３に嵌合して、第１ダネッジＤ１に複数の物品Ａを載置し、収容する。次いで、凸状支持部材７が、平板部６の上面に位置するような第２ダネッジＤ２を、第１ダネッジＤ１に載置された物品Ａの上方に配置した後、第２ダネッジＤ２の凸状支持部材７の台座円筒部７ａ内に、下に位置する第１ダネッジＤ１に載置された物品Ａの頭部ａ２を嵌合するとともに、凸状支持部材７の環状天板７ｂを、下に位置する第１ダネッジＤ１に載置された物品Ａの頭部ａ２の天板ａ２ａに載置する。
【００２２】
次いで、台座部ａ１が上で、頭部ａ２が下に位置するように、物品Ａを逆さ状態に配置した後、物品Ａの頭部ａ２の天板ａ２ａに穿設された透孔ａ２ｂに、第２ダネッジＤ２の凸状支持部材７の嵌合円筒部７ｃを嵌合するとともに、環状天板７ｂに、逆さ状態の物品Ａの頭部ａ２の天板ａ２ａを載置する。このようにすることにより、下に位置する第１ダネッジＤ１の上部嵌合部材２に、円柱状空間ａ３が嵌合された物品Ａの頭部ａ２の天板ａ２ａと、上に位置する第２ダネッジＤ２の凸状支持部材７の嵌合円筒部７ｃが、その天板ａ２ａに穿設された透孔ａ２ｂに嵌合された、逆さ状態の物品Ａの頭部ａ２の天板ａ２ａとが、第２ダネッジＤ２の環状天板７ｂを介して、対峙することになり、従って、第２ダネッジＤ２の環状天板７ｂを介して、下に位置する第１ダネッジＤ１に載置された正常状態の物品Ａと、上に位置する第２ダネッジＤ２に逆さ状態で載置された物品Ａとの対峙面積が大きいので、安定した状態で、物品Ａを、第１ダネッジＤ１及び第２ダネッジＤ２を用いて、段積みすることができる。
【００２３】
次いで、もう１つの第１ダネッジＤ１を、第２ダネッジＤ２の上方に配置した後、第１ダネッジＤ１の平板部１から下方に延在する下部嵌合部材３を、下に位置する第２ダネッジＤ２に逆さ状態で載置された物品Ａの円柱状空間ａ３に嵌合する。更に、上記のもう１つの第１ダネッジＤ１の平板部１の上面に形成された上部嵌合部材２に、台座部ａ１が上で、頭部ａ２が下に位置するように、正常に配置された物品Ａの円柱状空間ａ３を嵌合する。このようにすることにより、下に位置する第２ダネッジＤ２に逆さ状態で載置された物品Ａの台座部ａ１の底面ａ１ｂと、上に位置する第１ダネッジＤ１の上部嵌合部材２に、円柱状空間ａ３が嵌合された正常状態の物品Ａの台座部ａ１の底面ａ１ｂとが、第１ダネッジＤ１の平板部１を介して、対峙することになり、従って、第１ダネッジＤ１の平板部１を介して、下に位置する第２ダネッジＤ２に逆さ状態で載置された物品Ａと、上に位置する第１ダネッジＤ１に正常状態で載置された物品Ａとの対峙面積が大きいので、安定した状態で、物品Ａを段積みすることができる。
【００２４】
上述したように、第１ダネッジＤ１の上部嵌合部材２を、正常状態（台座部ａ１が下で、頭部ａ２が上に位置する状態）の物品Ａの円柱状空間ａ３に嵌合するようにして、第１ダネッジＤ１に、正常状態の物品Ａを載置する。次いで、第２ダネッジＤ２の凸状支持部材７の台座円筒部７ａ内に、下に位置する第１ダネッジＤ１に、正常状態で載置された物品Ａの頭部ａ２を嵌合するとともに、凸状支持部材７の環状天板７ｂを、下に位置する第１ダネッジＤ１に、正常状態に載置された物品Ａの頭部ａ２の天板ａ２ａに載置する。次いで、逆さ状態の物品Ａの頭部ａ２の天板ａ２ａに穿設された透孔ａ２ｂに、第２ダネッジＤ２の凸状支持部材７の嵌合円筒部７ｃを嵌合するとともに、環状天板７ｂに、逆さ状態の物品Ａの頭部ａ２の天板ａ２ａを載置する。このように、第１ダネッジＤ１と第２ダネッジＤ２とを用いることにより、第２ダネッジＤ２の環状天板７ｂを介して、下に位置する第１ダネッジＤ１に正常状態で載置された物品Ａと、上に位置する第２ダネッジＤ２に逆さ状態で載置された物品Ａとが、対峙面積が大きい状態で段積みされることになり、従って、安定した状態で、２段に、物品Ａを段積みすることができる。
【００２５】
３段に、物品Ａを段積みする場合には、上述したように、もう１つの第１ダネッジＤ１の下部嵌合部材３を、下に位置する第２ダネッジＤ２に逆さ状態で載置された物品Ａの円柱状空間ａ３に嵌合した後、上記のもう１つの第１ダネッジＤ１の上部嵌合部材２に、正常に配置された物品Ａの円柱状空間ａ３を嵌合する。このように構成することにより、下に位置する第２ダネッジＤ２に逆さ状態で載置された物品Ａの台座部ａ１の底面ａ１ｂと、上に位置する第１ダネッジＤ１の上部嵌合部材２に、円柱状空間ａ３が嵌合された正常状態の物品Ａの台座部ａ１の底面ａ１ｂとが、第１ダネッジＤ１の平板部１を介して、対峙することになり、従って、第１ダネッジＤ１の平板部１を介して、下に位置する第２ダネッジＤ２に逆さ状態で載置された物品Ａと、上に位置する第１ダネッジＤ１に正常状態で載置された物品Ａとが、対峙面積が大きい状態で段積みされることになり、安定した状態で、３段に、物品Ａを段積みすることができる。
【００２６】
第１ダネッジＤ１及び第２ダネッジＤ２を用いた４段以上の物品Ａの段積みは、上述した段積み方法を繰り返すことにより行うことができるので、その説明は省略する。
【００２７】
【発明の効果】

【００２８】
下に位置する第１ダネッジに正常状態で載置された物品と、上に位置する第２ダネッジに逆さ状態で載置された物品とが、対峙面積が大きい状態で段積みされることになり、従って、安定した状態で、物品を段積みすることができる。
【００２９】
下に位置する第１ダネッジに正常状態で載置された物品と、上に位置する第２ダネッジに逆さ状態で載置された物品とが、対峙面積が大きい状態で段積みされるとともに、下に位置する第２ダネッジに逆さ状態で載置された物品と、上に位置する第１ダネッジに正常状態で載置された物品とが、対峙面積が大きい状態で段積みされることになり、従って、安定した状態で、物品を段積みすることができる。
