【０００１】
【発明の属する技術分野】
本発明は，例えば壁面，天井面等の内外装のためにパネルを建築物の躯体に設置するに用いる着脱自在のスナップインパネル固定装置に関する。
【０００２】
【先行技術及び発明が解決しようとする課題】
この種のパネル固定は，下地材に対してパネルを直接にネジ止めしたり，例えばパネル設置用金具（ファスナー）を介してパネルをネジ止めするように，一般にネジ（ボルトを含む）を使用して行うものとされており，この場合ネジを操作して一度設置したパネルを取り外すことが可能であり，躯体との間の配線の点検等の各種メンテナンスに対応し得るし，設置工事で設置位置を間違えたパネルの張替えも可能となるが，多数箇所における締着作業が必要となり，パネル設置工事が煩雑化する傾向がある上，パネルの正面や側面のフランジにネジ（ネジ頭）が露出することを避け難く，特に，例えばロビー，ホール等の壁面や天井面等にあっては，設置パネルの外観が損なわれ易いという傾向を招き，その改善が求められている。
【０００３】
このため本発明者は，特願２００２−３２３０６号によって簡易な構造で作業性がよく，パネルの着脱を自在とし，更にネジ等の露出がなく外観が良好とし得るようにした着脱自在のスナップインパネル固定装置を提案済みであり，これによれば，定位置設置の下地材と，該下地材に設置して下地材側面との間に挿入溝を形成し且つその下地材対向面側に中間係止溝を設置した下地材側係止金具と，パネル端部に設置してその下地材対向面側に中間突起と先端突起をまた下地材側係止金具側に中間係止突起をそれぞれ設置し且つそのパネル端部近傍付近に透孔を設置した上記挿入溝に挿入用のパネル側係止金具とを備え，該パネル側係止金具を上記挿入溝に挿入し中間突起を下地材の正面に引掛け係止して先端突起を下地材側面に対接状態とするとともに中間係止突起を下地材側係止金具の係止溝にスナップイン係止することによってパネルを下地材に固定する一方，上記透孔を介して下地材側係止金具のパネル側先端を押圧して上記スナップイン係止を解除しパネルを下地材から取外し自在としたものとされる。
【０００４】
しかしこの場合パネルは下地材と下地材側係止金具の挿入溝にパネル側係止金具を挿入してパネル側係止金具を下地材側係止金具にスナップイン係止してパネルをスナップイン固定するものとされるから，着脱を繰り返すと，スナップイン固定したパネル毎に多数とされるいずれか又は複数のスナップイン係止が疲労し，パネル固定の保持力が弱まってパネルにガタツキや位置ズレ等を生じる可能性が残り，イベント会場等比較的短期使用のものは別としても，長期に亘って使用する場合にはパネル固定の耐久性が損われる可能性が残り，その解決が望まれる。
【０００５】
本発明はかかる事情に鑑みてなされたもので，その解決課題とするところは，パネルを着脱自在としつつもその固定を強固且つ確実に行って固定の耐久性を確保することによって実用性に富んだ着脱自在のパネルスナップイン固定装置を提供するにある。

請求項４に記載の発明は，同じく上記に加えて，上記下地材側係止金具における中間係止溝の鋭角角度が７５°程度を下回るとパネル側係止金具における中間係止突起の受入れが浅くなってスナップイン係止が不確実となる一方，また８５°程度を上回ると該中間係止突起の保持が緩くなってスナップイン係止の安定性が損われる可能性が生じることから，これを，上記下地材側係止金具における傾斜Ｖ字溝による中間係止溝の内角を８０±５°程度としてなることを特徴とする請求項１，２又は３に記載のパネル着脱自在のスナップイン固定装置としたものである。
【００１０】

【発明の実施の形態】
以下図面の例に従って本発明を更に具体的に説明すれば，１は，例えば樹脂系芯材と表裏のアルミ仕上材による複合パネル（商標名「アルポリック」）による内装又は外装用のパネル，１０は下地材であり，該パネル１はその四周に設置したパネル側係止金具３０を介して，下地材１０と該下地材１０に設置した下地材側係止金具２０間にスナップイン係止することによって該パネル側係止金具３０をこれら下地材１０と下地材側係止金具２０に常時強圧挟持自在とし，これら金具によるパネル保持力を可及的高度に発揮して，ガタツキや位置ズレ等の発生を抑制し長期に亘って固定の耐久性と安定性を維持確保することによって，パネルを着脱自在としつつもその固定を強固且つ確実に行って，その建物躯体に設置した下地材１０に対する固定の耐久性を確保したものとしてある。
【００１６】
即ち下地材１０は定位置に設置し，下地材側係止金具２０は該下地材１０に設置して下地材１０側面との間に挿入溝４０を形成し且つその下地材１０対向面側に中間係止溝２５を設置したものとし，パネル側係止金具３０は，パネル１端部に設置してその下地材１０対向面側に中間突起３３と先端突起３４をまた下地材側係止金具２０側に中間係止突起３５をそれぞれ設置し且つそのパネル１端部近傍付近に透孔３６を設置した上記挿入溝４０に挿入用のものとしてあり，上記パネル１の下地材１０への固定は，該パネル側係止金具３０を上記挿入溝４０に挿入し中間突起３３を下地材１０の正面に引掛け係止して先端突起３４を下地材１０側面に対接状態とするとともに中間係止突起３５を下地材側係止金具２０の中間係止溝２５にスナップイン係止することによって行ったものとする一方，上記透孔３６を介して下地材側係止金具２０のパネル１側先端を押圧して上記スナップイン係止を解除してパネル１を下地材１０から取外し自在としたものとしてあり，このとき下地材１０は，その側面を正面側に向けて幅狭とするように傾斜面とすることにより上記パネル側係止金具３０の先端突起３４をスナップイン係止前後で該傾斜面に対して摺動圧接自在とするとともに上記下地材側係止金具２０の中間係止溝２５は，これを挿入方向に傾斜開口した傾斜Ｖ字溝とし且つパネル側係止金具３０の中間係止突起３５を挿入方向逆向きに傾斜突出した傾斜突起とすることにより上記スナップイン係止を中間係止溝２５強制拡開状態の引掛け係止としパネル側係止金具３０を下地材１０と下地材側係止金具２０間に常時強圧挟持自在としてある。
【００１７】
本例の下地材１０は，例えばブラケット１４を介して建物躯体に縦横格子状をなすように設置した，厚肉中空のアルミ押出材によるものとしてあり，本例にあって上記側面は，例えば５乃至２０°程度とするように緩傾斜した傾斜面を有するものとして断面台形ボックス状とした厚肉中空の下地材基部１１と，その幅方向両側に張出突出した厚肉一対の固定突片１２，本例にあっては下地材基部１１から背面に向けた連結部を介して倒Ｌ字状をなすようにその先端から側方に向けて突出した固定突片１２とを備えて幅方向に対称断面形状のものとし，下地材基部１１の側面にそれぞれ下地材側係止金具２０設置による上記挿入溝４０を形成することによって下地材１０の両側に上記パネル１端部を固定してその設置を行うようにしてあり，このときパネル１端部間を離隔して下地材１０正面，即ち下地材基部１１の正面を開放するか又は必要に応じて開放自在に閉鎖するようにした縦方向又は横方向の溝状の目地４１を配置してそのパネル１固定を行うものとしてある。
【００１８】

【００２０】
傾斜片２３は，その傾斜角度を，例えばパネル１背面の直交線と下地材側に３０±５°程度とするように傾斜したものとし，係止片２４はこれより緩やかな傾斜角度，例えば同じく直交線と１０°程度以下の傾斜又は傾斜０°としたものとし，これによって該係止片２４に形成した中間係止溝２５にパネル側係止金具３０の中間係止突起３５をスナップイン係止することにより挿入溝４０側に向けた強力なスプリング性を発揮して該スナップイン係止を可及的に強固に行なってその耐久性を確保するようにしてあり，このとき下地材１０に重合固定した固定片２１を側方に延長するとともに傾斜片２３の屈曲延設を湾曲部２２を介して行なうことによって下地材側係止金具３０のスプリング性を更に強固とするように向上し，例えば下地材１０の固定突片１２端縁に沿うようにＬ字状に屈曲する等した場合に生じる該屈曲部分に対するスナップイン係止に伴う力の集中を回避し，その耐久性の向上を図るようにしてある。
【００２１】
係止片２４に設置した本例の中間係止溝２５は，係止片２４に起立片部２６を設けることによってこれを画するようにし，上記挿入方向に傾斜開口することによって挿入溝４０の内方奥行方向に傾斜した開口を備えた，その内角を８０±５°程度としてあり，これによってパネル側係止金具３０の中間係止突起３５を該中間係止溝２５を強制拡開した状態に引掛け係止するものとして，上記スナップイン係止を可及的強固且つ確実に行うとともにこれが外れたり緩んだりする可能性を解消するものとしてある。
【００２２】
押圧片２７は，係止片２４における中間係止溝２５を画する起立片部２６先端から中間係止溝２５と逆向きのＶ字状をなすように挿入方向逆向きにして挿入溝４０の外方に向けて突出することによってパネル側係止金具３０の先端突起３４の摺動ガイドをなして該先端突起３４が上記傾斜片２３と係止片２４をそのスプリング力に抗して外側に拡開してこれを通過復帰してその引掛け係止を確実且つ強固になし得るようにする一方，その先端部分に上記透孔２８を透設して設置してあり，これによってパネル側係止金具３０の透孔３６から引掛け工具５０等によって押圧片２７を上記目地側に引寄自在として下地材側係止金具２０に変形を来した場合にその形状の矯正による補修をなし得るようにしてある。

中間突起３３と先端突起３４は，その下地材１０側の先端が直角のＬ字面上に位置するように配置し，中間突起３３は下地材１０正面に引掛け係止するように下地材１０側に突出し，先端突起３４は基部３２先端から下地材１０側面の傾斜面に所定位置，本例にあってはパネル側係止金具３０のスナップイン係止の定位置の僅かに手前位置のＰ点で接触し，スナップイン係止のための押圧，特に圧入によって先端突起３４が傾斜面をＰ点より挿入溝４０の奥行方向に向けて上記摺動圧接するようにしてあり，このとき本例の先端突起３４は，これを，上記下地材１０の傾斜面に線接触自在の形状に形成し，これによって傾斜面に対する摩擦抵抗を可及的に減少して押圧を容易化し得るようにしてある。
【００２６】
傾斜突起とした中間係止突起３５は，例えば基部３２と４０°乃至５０°程度，本例にあっては４５°程度の角度のＶ字状を呈して上記下地材側係止金具３５の押圧片２７の突出方向と逆に挿入方向逆向きに傾斜突出してあり，このとき本例の中間係止突起３５先端は，挿入方向上面から正面にかけて湾曲し又は挿入方向上面側に膨出する等することによって円弧状の面を備えたものとし，上記下地材側係止金具２０の摺動ガイドをなすようにした上記起立片部２６に沿ってこれを押圧しながら容易に乗越えてその中間係止溝２５にスムーズに引掛け係止し得るようにしてある。また中間係止突起３５先端は，その大きさ，傾斜角度等とともに上記中間突起との位置関係を規制して，該突起３５が上記下地材１０正面に対接したその引掛け係止状態で下地材側係止金具２０の中間係止溝２５を強制拡開状態とするようにしてある。
