Description

【０００１】
【発明の属する技術分野】
この発明に係る組付け構造は、部材相互を確実に組付けると共に、組付け具を備えた側の部材に設けられている操作穴よりの押動操作のみによって、部材相互の組付けを容易に解除することのできる組付け構造の提供に関する。
【０００２】
【従来の技術】
部材相互を組付ける組付け構造には、その組付けの目的に対応した夫々の形態の組付け構造が要求されており、例えば、板状部材の組付けにあって、この組付けられる板状部材を、その組付け後に解除可能とする組付け構造の提供が求められることがあった。
【０００３】
かかる要求に対応する組付け構造に用いられる留め具として、例えば、実公平５−６４０８号の実用新案出願公告公報所載の考案に係る留め具が、板状部材の組付け手段として、その組付け後にあって、その組付け状態を解除できる留め具として提案されている。
【０００４】
この実公平５−６４０８号公報所載の考案に係る留め具は、２枚の板状部材を結合する手段として、外方に開き出す脚部を、その頭部から延びる中空管状の形態をなすものとして備え、しかも、この頭部に、この脚部の内径孔に連通する貫通孔を備えた第１の留め具部分と、この第１の留め具部分の頭部の貫通孔、及びその脚部の内径孔に挿入される頭部及び脚部とを備えた第２の留め具部分とを有し、板状部材に設けた貫通孔に対して、第１の留め具部分の脚部を挿通し、この第１の留め具部分の貫通孔から脚部の内径孔内に挿し入れられている第２の留め具部分を更に押し入れることによって、この第２の留め具部分の脚部を拡開し、これによって、第１の留め具部分の脚部を拡開することで、この第１の留め具部分の脚部と頭部との間で、各板状部材の組付けをなすようにしていた。
【０００５】
【発明が解決しようとする課題】
この実公平５−６４０８号公報所載の考案に係る留め具にあっては、重ね合せられた板状部材を、第１の留め具部分の頭部と、第２の留め具部分によって開き出された第１の留め具部分の脚部とによって挾持状態に留めつける構成としてあることから、比較的薄手の板状物などの留めつけに都合の良い反面、厚手の板状物の留めつけには不向きであった。
【０００６】
また、第１の留め具部分の脚部を、重ね合せの状態とされている板状物の貫通孔に挿通し、これを該貫通孔の挿通前方側で撓ませると共に、この撓められた脚部と、該第１の留め具部分の頭部とによって、重ね合せの状態にある板状物の貫通孔の各孔縁を挾持させる構成としてあることから、この貫通孔から前方に向けて突き出されている脚部が、かかる撓み込みによる孔縁の保持を可能とする形態、より具体的には、かかる撓み変形に伴う孔縁の挾持を可能つする突き出し寸法を備えたものとして構成される必要があった。
【０００７】
また、この実公平５−６４０８号公報所載の考案に係る留め具にあっては、この第１の留め具部分の脚部の開き出し、及び、この開き出されている脚部の弾性復帰に用いられる第２の留め具部分の脚部が、その組み付け、及び組み外しの操作に際して、この第１の留め具部分の脚部から、前方に、比較的大きく突き出される構成とされていた。
【０００８】
この発明は、かかる板状部材の取付けにあって、厚手の板状部材の組付けにも適し、しかも、組付けられる板状部材の内部方に、組付け具における係合手段などの撓み変形のための大きな操作空間を設ける必要のない組付け構造の提供を目的としている。
【０００９】
【課題を解決するための手段】

【００１１】
このように組付け具によって組付けられる第１の部材と、第２の部材とは、この組付け具に備えられている操作体が、第２の部材に設けられている操作受け面に向けて移動可能、且つ、この操作受け面に押しつけられて、その解除片を側方に向けて開き出し可能とするように組付けられており、第１の部材の操作穴から、棒状の操作手段などを用いて、この操作体を、第２の部材における操作受け面に押しつけ、この操作体の解除片を側方に開き出すと共に、この開き出された解除片によって、第２の部材の引っ掛け手段に掛合されている弾性掛合片の掛合を解き、これによって、第１の部材と、第２の部材との組付け状態を解除することができる。
【００１２】
また、請求項２記載の発明に係る組付け構造を、前記目的を達成するために、前記請求項１記載の発明に係る組付け構造にあって、組付け具が、該組付け具を第２の部材に組み付ける際に該第２の部材に接する接触部を有する少なくとも一対の脚片を、該組付け具の第１の部材に対する取付け部から弾性掛合片と同一の向きに突設してあると共に、この対をなす脚片間に第２の部材の操作受け面に接する弾性片が設けられている構成としてある。
【００１３】
このように構成される組付け構造にあっては、第１の部材に取付けられている組付け具における脚片の接触部を第２の部材に接した状態で、第１の部材と、第２の部材とが組付け具によって組付けられると共に、第２の部材が、この第２の部材における操作受け面に接する組付け具の弾性片によって該組付け具に対して弾性的に組付けられる。
【００１４】

以下、本発明に係る組付け構造の典型的な一実施の形態について詳細に説明する。
【００１５】

【００１６】
この実施の形態に係る組付け構造は、第１の部材Ｂと第２の部材Ｃとの組み付けに構造に関し、典型的には、操作穴３１を有する第１の部材Ｂと、引っ掛け手段４１及び操作受け面４２とを有する第２の部材Ｃと、前記第１の部材Ｂに取付けられる取付け部１１と前記第２の部材Ｃに掛合される弾性掛合片１３とを一体に有し、且つ前記第２の部材Ｃの操作受け面４２に押し付けられて側方に開き出されると共に前記第２の部材Ｃに掛合される弾性掛合片１３の掛合を解く向きに該弾性掛合片１３を押動する解除片２２を有している操作体２０を前記取り付け部１１の取り付け面１１ａ側から該弾性掛合片１３に沿って構成されている操作空所Ｙに移動可能に備えている組付け具Ａとを有して構成してあり、この組付け具Ａが、この組付け具Ａに備えられている操作体２０を前記第１の部材Ｂにおける操作穴３１から押動操作可能となるように該第１の部材Ｂに取り付けてあると共に、前記第１の部材Ｂまたは該第１の部材Ｂに取り付けられている組付け具Ａが前記第２の部材Ｃに接するように、しかも、該第２の部材Ｃにおける操作受け面４２に対して前記操作体２０の押し付けを可能とするように、該組付け具Ａの弾性掛合片１３を前記第２の部材Ｃの引っ掛け手段４１に引っ掛けるようにして、該第２の部材Ｃを前記第１の部材Ｂに組み付けてある構成としてある。
【００１７】
このように構成される組付け構造にあっては、第１の部材Ｂに対して、この第１の部材Ｂの操作穴３１から操作体２０の押動操作を可能とするように組付け具Ａを組付けると共に、第１の部材Ｂ又は該第１の部材Ｂに取り付けた組付け具Ａを、前記第２の部材Ｃに当接させた状態で、この第２の部材Ｃの引っ掛け手段４１に対して前記組付け具Ａの弾性掛合片１３を掛合させることによって、第１の部材Ｂに対して第２の部材Ｃの組付けをなすことができる。
【００１８】
このように組付け具Ａによって組付けられる第１の部材Ｂと、第２の部材Ｃとは、この組付け具Ａに備えられている操作体２０が、第２の部材Ｃに設けられている操作受け面４２に向けて移動可能、且つ、この操作受け面４２に押しつけられて、その解除片２２を側方に向けて開き出し可能とするように組付けられており、第１の部材Ｂの操作穴３１から、ドライバーなどの棒状の操作手段などを用いて、この操作体２０を、第２の部材Ｃにおける操作受け面４２に押しつけ、この操作体２０の解除片２２を側方に開き出すと共に、この開き出された解除片２２によって、第２の部材Ｃの引っ掛け手段４１に掛合されている弾性掛合片１３の掛合を解き、これによって、前記第１の部材Ｂと第２の部材Ｃとの組付け状態を解除することができる。
【００１９】
次いで、前記の構成に係る組付け構造にあって、組付け具Ａが、該組付け具Ａを第２の部材Ｃに組み付ける際に該第２の部材Ｃに接する接触部１２ａを有する少なくとも一対の脚片１２、１２を、該組付け具Ａの第１の部材Ｂに対する取付け部１１から弾性掛合片１３と同一の向きに突設してあると共に、この対をなす脚片１２、１２間に第２の部材Ｂの操作受け面４２に接する弾性片１４が設けられている構成としたことを、他の典型的な実施の形態の一つとしている。
