Description

【０００１】
【発明の属する技術分野】
本発明は、パンタグラフ機構と、パンタグラフ機構に連結された複数の縦枠材とを備えた伸縮門扉に関するものである。
【０００２】
【従来の技術】
従来、この種の伸縮門扉は、一般に、吊元側支柱と戸当たり側支柱の間に設けられた門扉本体の伸縮方向に配置した複数本の縦枠材と、複数本の傾斜リンクを交差状に組み合わせて伸縮自在に構成されたパンタグラフ機構とを備えており、パンタグラフ機構の交差部に各縦枠材を連結した構造になっている。詳細には、パンタグラフ機構は各傾斜リンクがその交差位置において枢軸により連結されたものであり、上下方向へほぼ真っ直ぐな部材により構成された縦枠材に、固定枢軸（縦枠材に対して上下へ移動しない枢軸）が位置固定され、可動枢軸（縦枠材に対して上下へ移動する枢軸）が上下方向へスライド可能に連結されている。
【０００３】
【発明が解決しようとする課題】
しかし、従来の伸縮門扉は、縦枠材を鉛直方向に真っ直ぐな縦長の部材で構成しているため、縦枠材の形状が変化に乏しく、伸縮門扉を広げたときの全体のデザインに変化を持たせることが困難で、デザインが単調になりがちであった。
【０００４】
したがって、本発明の解決すべき技術的課題は、縦枠材の形状に変化を与えることにより門扉の全体的なデザインに多様性を持たせることのできる伸縮門扉を提供することである。
【０００５】
【課題を解決するための手段】
本発明は、複数本の右上がり傾斜リンク11と左上がり傾斜リンク12とを交差状に組み合わせて伸縮自在に構成されたパンタグラフ機構7 と、該パンタグラフ機構7 の交差部に枢軸19,21 を介して連結された複数本の縦枠材6,53とを備えた伸縮門扉において、前記縦枠材6,53の左右両側で前記パンタグラフ機構7 の前後両側に配置され且つその上下両端部が前記縦枠材6,53の上下両端部側の連結部材 14,15 に上下方向にスライド自在に挿入された縦方向の装飾部材38と、前記縦枠材6,53の左右両側で前記傾斜リンク11,12 に固定され且つ前記パンタグラフ機構7 の伸縮に連動して左右の前記装飾部材38の上下方向の中間部間の間隔が前記パンタグラフ機構 7 の伸長時に広がり収縮時に狭まるように該各装飾部材38に対してその長手方向にスライド自在に係合する係合具40とを備えたものである。
【０００６】
【発明の実施の形態】
以下に、本発明に係る伸縮門扉の実施形態について添付図面を参照して詳細に説明する。まず、図１から図８に示した第１実施形態について説明する。
図１はこの伸縮門扉を伸ばした状態の正面図、図２は平面図、図３は門扉を閉じた状態の正面図である。
【０００７】
図において、1 は吊元側支柱、2 は戸当たり側支柱であり、各支柱1,2 はガレージ等の出入り口部の左右両側において地面に立設されている。3 は伸縮式の門扉本体で、ガレージ等の出入り口部を開閉するように、吊元側支柱1 と戸当たり側支柱2 との間に伸縮自在に設けられている。この門扉本体3 は、伸縮方向の両端に配置された吊元側端枠4 及び戸当たり側端枠5 と、これらの両端枠4,5 の間で門扉の伸縮方向に等間隔で配置された複数（この実施形態では、図３に示すように１０本）の縦枠材6 と、両端枠4,5 と各縦枠材6 を連結するパンタグラフ機構7 とを備えている。
【０００８】
両端枠4,5 は、角筒状の部材から構成されている。吊元側端枠4 は、吊元側支柱1 に対し、蝶番8 を用いて上下２個所で連結されており、門扉本体3 を吊元側支柱1 に対してガレージ等の敷地の内側と外側の両方へ開くことができるようになっている。戸当たり側端枠5 は、前後面に開閉操作用の把手9 を備え、把手9 の上方には、門扉本体3 を閉状態で戸当たり側支柱2 に施錠するための施錠装置（図示せず）を備えている。この戸当たり側端枠5 の下端と、戸当たり側端枠5 の方から数えて５番目の縦枠材6 の下端には、前後両端にキャスター10が取り付けられており、門扉を開閉操作するときにキャスター10が地面を転がって操作力を軽減するようになっている。
【０００９】
パンタグラフ機構7 は、水平方向へ一定間隔で配置した右上がり傾斜リンク11の後方に、左上がり傾斜リンク12を同じ間隔で配置し、両傾斜リンク11,12 を、その交差部において枢軸19,20,21を用いて連結したものである。各傾斜リンク11,12 には、角パイプ状の中空部材が用いられている。パンタグラフ機構7 の両端部は、それぞれ短リンク11a,12a が２本ずつ用いられており、短リンク11a,12a を連結した枢軸が両端枠4,5 に位置固定状態で保持され、その上下に位置するリンク端が、両端枠4,5 に上下方向へスライド可能に保持されている。
【００１０】
図４は図１のＡ−Ａ線拡大断面図、図５は図１のＢ−Ｂ線拡大断面図、図６は図１のＣ部拡大図、図７は図４のＤ−Ｄ線拡大断面図である。縦枠材6 は、図４に示すように、パンタグラフ機構7 の右上がり傾斜リンク11と左上がり傾斜リンク12の間で鉛直方向沿いに配置された縦桟13と、縦桟13の上下の端部において門扉の前後方向沿いに固定配置された連結部材14（上側）及び15（下側）とから構成されている。縦桟13は、図５に概略の断面形状を示すように、アルミニウムなどの軽金属で成形された異形のＨ型材で、角パイプのように中空に形成された両縁のフランジ部16と、両フランジ部16を厚さ方向の中央で連接するウェブ17とを有し、ウェブ17の前後の空間が両フランジ部16の間で縦溝18（図６参照）になっている。
【００１１】
パンタグラフ機構7 の固定枢軸19は、この縦桟13のウェブ17を貫通しており、それによって縦桟13に対する固定枢軸19の位置固定がなされている。固定枢軸19の両隣の枢軸20は、固定枢軸19と同様に右上がり傾斜リンク11と左上がり傾斜リンク12を直接に連結する一本の軸であるが、各リンク11,12 の両端を連結している可動枢軸21は軸方向の中央部で前後二つに分断されており、その前方部分及び後方部分が、それぞれ縦桟13の縦溝18に対してウェブ17の前方及び後方から嵌入している。この可動枢軸21は、外径が縦溝18の幅よりもわずかに小さく、縦溝18内を上下にスライドできるようになっている。なお、可動枢軸21を前後に分断せずに一本の軸とし、縦桟13のウェブ17を可動枢軸21の動作範囲だけ切り欠いた構成にしてもよい。
【００１２】
図５及び図６に示すように、縦桟13の縦溝18には、可動枢軸21の可動範囲を除き、溝形の封止部材22がはめ込まれて固定されている。封止部材22は、図７に示すように、前壁23と、その両側に直角に連接した側壁24とを有し、側壁24の先端に、左右両側へ突出する爪25を備えている。そして、この爪25が、縦桟13の縦溝18の奥に形成された係止凹部26に係止している。
【００１３】
縦桟13の上下端部に固定された連結部材14,15 は、縦桟13と連結部材14との連結構造を示す図８（ａ）に示すように、角パイプ状の連結部材本体27と、カバー28とから構成されている。上側の連結部材14と下側の連結部材15はカバー28の形状のみ異なり、カバー28は、上側では断面半円形、下側では断面コの字形（図示せず）になっている。連結部材本体27は、縦桟側の内面壁29、反縦桟側の外面壁30、これらを連接する２面の側壁31から構成され、側壁31は、内面壁29側の端縁が内面壁29よりも少し突出している。
【００１４】
側壁31には、カバー28の両端縁に形成された爪32をはめ込んで留めるための保持凹部33が形成されている。連結部材14,15 の両端面はエンドプレート34で封止され、連結部材14,15 の内部の構造が外から見えないようになっている。この図に示すように、縦桟13と連結部材本体27とはビス35で固定され、縦桟13は、図７に示すように、ビス35をねじ込んで固定するための固定部36を有している。なお、この固定部36は図５では図の簡略化のために省略している。
【００１５】
各連結部材本体27の内面壁29は、図７に示すように四隅に開口37を有している。縦桟13の上端に固定された連結部材本体27の開口37には、断面ほぼＵ字形状の型材からなる装飾部材38の上端部が該装飾部材38の長手方向へスライド可能に挿入され、縦桟13の下端に固定された連結部材本体27の開口37には、装飾部材38の下端部が長手方向へスライド可能に挿入されている。この構成により、装飾部材38は、縦桟13に沿って縦方向に延在し、かつ縦枠材6 に対して左右両側に位置するようになっている。なお、各連結部材本体27の開口37は、必ずしも別々に設ける必要はなく、連結部材本体27の両端の２つの開口37,37 を１つにし、その中に挿入した２本の装飾部材38間の隙間に、ゴムなどの弾性体を装着するようにしてもよい。
【００１６】
装飾部材38はアルミニウムなどの軽金属製の型材で、全体が弾性を有しており、両端部に内側への折り返し部39が形成されている。この装飾部材38は、上下に相対する一対の連結部材本体27の外面壁30間の内寸よりも全長が少し短く、連結部材14に対する装飾部材38の装着状態を示す断面図である図８（ｂ）に示すように、上側の連結部材14内においてのみ、連結部材本体27の外面壁30と装飾部材38の端面との間に隙間ができるようになっている。
【００１７】
各装飾部材38は、各傾斜リンク11,12 に対して、固定枢軸19から所定距離を隔てた位置で係合具40により連結されている（図１）。この連結位置は、門扉本体3 を収縮したときに、連結部材14,15 の間で真っ直ぐになった装飾部材38が傾斜リンク11,12 と交わる位置であり、この位置で装飾部材38と傾斜リンク11,12 とを連結するため、係合具40として丸パイプからなるピンを用いている（図５）。
【００１８】
係合具40は、角パイプで構成された傾斜リンク11,12 の内側の側壁にその一端がリベット41で固定され、他端が装飾部材38の折り返し部39からＵ字状の湾曲部の方へ向かって挿入され、装飾部材38に対してスライド可能になっている。なお、実施形態では装飾部材38を連結部材14,15 に対してスライド可能にしているので、係合具40と装飾部材38はスライドしない構成であってもよい。また、装飾部材38と傾斜リンク11,12 を連結する部材は、パイプなどによるピン形状の部材に限らず、適当な形状の部材を適宜選択して用いればよい。
【００１９】
次に、本実施形態の伸縮門扉を開閉するときの操作について説明する。門扉本体3 を図１の状態から収縮させる場合には、把手9 を吊元側支柱1 の方へ押して行けばよい。そうすると、図１において各右上がり傾斜リンク11が固定枢軸19を中心として反時計回りに、左上がり傾斜リンク12が時計回りに傾動しながら各縦枠材6 の間隔が狭まって行き、図３の状態まで縮めることができる。このようにして門扉を収縮させるとき、装飾部材38と傾斜リンク11,12 とを連結した係合具40は、各傾斜リンク11,12 の傾動に伴い、各固定枢軸19に対して、その固定枢軸19との水平間隔が小さくなる方向へ移動して、図３の状態になったときに、各装飾部材38が縦桟13に沿って真っ直ぐにのびた状態となる。
【００２０】
逆に門扉本体3 を図３の状態から伸長させる場合は、把手9 を戸当たり側支柱2 の方へ引っ張って行けばよく、そうすれば、各傾斜リンク11,12 が門扉本体3 を収縮させる場合とは逆の方向へ傾動しながら、各縦枠材6 の間隔が広がっていく。そして、戸当たり側端枠4 が戸当たり側支柱2 まで達したところで施錠装置をロックすれば、ガレージ等の出入り口を塞ぐことができる。
【００２１】
このようにして門扉を閉じて行くとき、装飾部材38は、各傾斜リンク11,12 との連結用の係合具40が固定枢軸19に対して水平方向へ離れて行くために徐々に弓形に湾曲し、門扉を閉じたときに湾曲の度合いが最も大きくなる。この時の湾曲の度合いをさらに大きくしたい場合は、固定枢軸19と係合具40との間隔をより広く設定しておけばよいが、その場合は、係合具40を傾斜リンク11,12 の幅方向において中心からずらした位置に設けておけば、門扉本体3 を収縮したときに、装飾部材38を真っ直ぐな状態になるようにすることは可能である。
【００２２】
なお、門扉を伸長して出入り口を閉じたときには装飾部材38が湾曲するため、各縦枠材6 に対して左右に位置する各対の装飾部材38の外寸が広くなり、門扉を収縮したときにもこの寸法が変わらなければガレージ等の出入り口の開口幅が小さくなるが、上記実施形態において門扉を収縮したときには各装飾部材38が真っ直ぐになってその外寸が狭くなるので、門扉の収縮時に出入り口の開口幅が小さくなるような不都合は生じない。
【００２３】
以上説明したように、本実施形態の門扉は、縦枠材6 に対して左右両側に配置された各対の装飾部材38の間隔がパンタグラフ機構7 の伸縮に連動して変化するため、門扉を閉じたときと開いたときとで外観が異なるという従来の門扉には見られなかった視覚上顕著な効果を奏することができる。一方、縦桟13をパンタグラフ機構7 の右上がり傾斜リンク11と左上がり傾斜リンク12の間に配置し、装飾部材38をパンタグラフ機構7 の前後に配置したことによって、意匠部材であって任意にデザインすることのできる装飾部材38を、構造部材であってデザインに変化を持たせにくい縦桟13よりも外観上引き立たせ、ひいては門扉全体の意匠性を向上させることができるという効果もある。
【００２４】
次に、図９に示した第２実施形態について説明する。この門扉は、第１実施形態の門扉とは、パンタグラフ機構7 に縦枠材6 を連結した位置と、各装飾部材38が係合具40により傾斜リンク11,12 に２個所で連結された点とが異なっている。この実施形態では、仮想線ｃ上の（下から２段目の）枢軸が縦桟13に位置固定される固定枢軸19になっており、この固定枢軸19の垂直上方に位置する枢軸が可動枢軸21になっている。なお、縦枠材6 と縦枠材6 の間で縦に３つ並んだ枢軸20は、単に各リンク11,12 を傾動可能に連結している。装飾部材38は、固定枢軸19の両隣と可動枢軸21の両隣で、係合具40により傾斜リンク11,12 に連結されている。係合具40は、第１実施形態で説明したのと同じく、門扉を収縮したときに装飾部材38が真っ直ぐになるように、固定枢軸19及び可動枢軸21に対して間隔が設定されている。
【００２５】
図１０は第３実施形態を示している。この門扉は、パンタグラフ機構7 を上下２段に配置し、各パンタグラフ機構7 の固定枢軸19が縦枠材6 に位置固定され、その上下の可動枢軸21が縦枠材6 にスライド可能に連結されている。装飾部材38は、各固定枢軸19の両隣で傾斜リンク11,12 に連結されている。
【００２６】
図１１（ａ），（ｂ）は第４実施形態を示している。この実施形態は、２種類の縦枠材6,42を、第１実施形態の縦枠材6 の位置に交互に配置したものである。第１の縦枠材6 は第１実施形態の縦枠材6 と同じ構成であり、門扉本体3 の伸縮時に装飾部材38が変形するようになっている。第２の縦枠材42は、側面図である図１１（ｂ）に示すように、前縦桟43と後縦桟44とを上端及び下端の連結桟45,46 で一体に連結したものである。各縦桟43,44 及び連結桟45,46 には例えば角パイプやＣ型チャンネル材などを使用することができる。縦桟43,44 に固定枢軸19が位置固定され、可動枢軸21が上下方向へスライド可能に連結されている。
【００２７】
図１２は第５実施形態を示している。この実施形態の門扉は、第１実施形態の門扉に、第２の縦枠材47を追加したものである。この第２の縦枠材47は、第４実施形態の第２縦枠材42とほぼ同じ構成であるが、高さ寸法が少し小さく、パンタグラフ機構7 を図示のように伸長した状態で上端が第１縦枠材6 の上端よりも少し下がった位置になるように枢軸20a が位置固定されている。また、その下の枢軸20b は第２縦枠材47に上下方向へスライド可能に連結されている。そして、パンタグラフ機構7 を収縮したときには、第１縦枠材6 と第２縦枠材47の上端の高さが揃うようになっている。
【００２８】
図１３（ａ），（ｂ）は第６実施形態を示している。この門扉の縦枠材48は、装飾部材49の構成が前記各実施形態とは異なっている。各装飾部材49は、それぞれが２点において、係合具40により、各傾斜リンク11,12 に対してスライドせず、傾動のみが可能なように連結されている。装飾部材49は、中央の装飾部50と両端の連結部51が別部材で構成されており、装飾部50にＣ形チャンネル材が用いられ、連結部51に角パイプが用いられている（材料はこれらに限るものではない）。
【００２９】
連結部51の角パイプは装飾部50のＣ形チャンネル材に回動可能に連結されており、詳細には、図１３（ｂ）に示すように、装飾部50の両端に、角パイプの一方の側壁を切り欠いた連結部51の端部を被せ、これらをリベット52などの連結手段で連結している。これにより装飾部材49は、傾斜リンク11,12 との連結位置と、連結部材14,15 との連結位置の間で屈曲自在に構成されている。
【００３０】
装飾部50の両端は、門扉の伸縮時に装飾部50と連結部51の動作を妨げないように、リベット52を中心とする円弧に沿った形状に形成されている。連結部51の反装飾部側の端部（つまり装飾部材49の両端部）は、前記各実施形態と同様に連結部材14,15 にスライド可能に挿入されている。この構成においては、装飾部材49に弾性変形可能な素材を用いる必要はない。
【００３１】
なお、この第６実施形態の門扉の装飾部材49において、連結部51の角パイプを用いず、装飾部50のＣ形チャンネル材（材料はこれに限るものではない）のみを装飾部材として用い、上下の端部は連結部材14,15 に挿入せずにフリーにしておいてもよい。そうすれば、門扉の伸縮時に、この場合の装飾部材である装飾部50が真っ直ぐなまま縦桟13に対して平行に移動して縦桟13との間隔が変化するようになり、上記各実施形態とは違った視覚上の効果を得ることができる。
【００３２】
図１４（ａ），（ｂ），（ｃ）は第７実施形態を示し、（ａ）は正面図、（ｂ）は前縦桟の下端部の部分拡大斜視図、（ｃ）は傾斜リンク11,12 と装飾部材38との連結構造を示す部分断面図である。この門扉の縦枠材53は、第４実施形態の第２縦枠材42を利用しており、前後の縦桟43,44 の上下の端部にパンタグラフ機構の伸縮方向に沿って連結部材54を固定し、この連結部材54で装飾部材38をスライド可能に連結保持している。その他の構成は前記各実施形態と同様であるので説明は省略する。この構成では、各縦桟43,44 と装飾部材38が並列しているので、前記各実施形態の門扉とは違った視覚上の効果を得ることができる。
【００３３】
なお、本発明は上記各実施形態に限定されるものではなく、その他種々の態様で実施することが可能である。例えば、装飾部材38は、パンタグラフ機構7 の前後両方でなく、前後どちらか一方のみに設けてもよい。また、装飾部材38を縦桟13の左右に２本ずつ設けてもよいし、縦枠材6 の一本おきや数本おきに装飾部材38の本数や配置を変えてもよい。さらに、装飾部材38を任意の縦枠材6 に対して左右いずれか一方に設けたり、門扉の右半分と左半分で縦枠材6 に対する装飾部材38の配置を変えて全体として調和のとれた配置にしたりすることもできる。
【００３４】
傾斜リンク11,12 と装飾部材38を連結する係合具40は、第１及び第３〜第５実施形態においては固定枢軸19の両隣に設け、第２実施形態においては固定枢軸19と可動枢軸21の両隣にそれぞれ設けているが、装飾部材38の上下の端部を連結部材14,15 に連結しない場合（第６実施形態の変形例として説明したもの）に２本必要であるのを除いては、リンク交差部の少なくとも１個所に設ければよく、例えば、可動枢軸21の隣にのみ設けたり、リンク交差部のすべてに設けたりすることもできる。
【００３５】
また、上記各実施形態において、装飾部材38,49 の上下の端部は、連結部材14,15,54に挿入せずに、縦桟13,43 に対してスライド可能に連結してもよい。その連結部の構造としては、例えば、装飾部材38,49 の上下の端部に長孔を形成し、この長孔と係合するピンを縦桟13,43 に設ける構造などが可能である。さらに、装飾部材38,49 の上下両端部を覆って見えないようにするためのカバー部材を縦桟13,43 の上下両端部に固定しておき、このカバー部材と装飾部材38,49 を長孔とピンなどでスライド可能に連結してもよい。このように、縦枠材6,48,53 側の部材（縦桟13,43 や連結部材14,15,54）と装飾部材38,49 との連結構造は、適宜定めればよい。
【００３６】
【発明の効果】
本発明は、複数本の右上がり傾斜リンク11と左上がり傾斜リンク12とを交差状に組み合わせて伸縮自在に構成されたパンタグラフ機構7 と、該パンタグラフ機構7 の交差部に枢軸19,21 を介して連結された複数本の縦枠材6,53とを備えた伸縮門扉において、縦枠材6,53の左右両側でパンタグラフ機構7 の前後両側に配置され且つその上下両端部が縦枠材6,53の上下両端部側の連結部材 14,15 に上下方向にスライド自在に挿入された縦方向の装飾部材38と、縦枠材6,53の左右両側で傾斜リンク11,12 に固定され且つパンタグラフ機構7 の伸縮に連動して左右の装飾部材38の上下方向の中間部間の間隔がパンタグラフ機構 7 の伸長時に広がり収縮時に狭まるように該各装飾部材38に対してその長手方向にスライド自在に係合する係合具40とを備えているので、門扉の外観が閉じたときと開いたときとで異なるという、従来の門扉では得られなかった視覚上の効果が得られるとともに、装飾部材38の位置、本数、形状などを変えるだけで、門扉のデザインに多様性を持たせることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a telescopic gate provided with a pantograph mechanism and a plurality of vertical frame members connected to the pantograph mechanism.
[0002]
[Prior art]
Conventionally, this type of telescopic gate generally crosses a plurality of vertical frame members arranged in the expansion and contraction direction of the gate body provided between the suspension side column and the door-end column and a plurality of inclined links. And a pantograph mechanism configured to be stretchable in combination with each other, and each vertical frame member is connected to an intersection of the pantograph mechanisms. Specifically, in the pantograph mechanism, each inclined link is connected by a pivot at the intersecting position, and a vertical frame member constituted by a member that is substantially straight in the vertical direction is fixed to a fixed pivot (up and down with respect to the vertical frame member). The pivot that does not move to the vertical position is fixed, and the movable pivot (the pivot that moves up and down with respect to the vertical frame member) is connected to be slidable in the vertical direction.
[0003]
[Problems to be solved by the invention]
However, the conventional telescopic gate is composed of a vertically long member that is straight in the vertical direction, so the shape of the vertical frame material is rarely changed, and the overall design when the telescopic gate is widened has changed. It was difficult to hold and the design tended to be monotonous.
[0004]
Therefore, a technical problem to be solved by the present invention is to provide an extendable gate that can give diversity to the overall design of the gate by changing the shape of the vertical frame member.
[0005]
[Means for Solving the Problems]
The present invention includes a pantograph mechanism 7 that is configured to be extendable by combining a plurality of right-upward inclined links 11 and left-upward inclined links 12 in an intersecting manner, and pivots 19 and 21 at intersections of the pantograph mechanism 7. In the telescopic gate provided with a plurality of vertical frame members 6, 53 connected to each other, the left and right sides of the vertical frame members 6, 53 are arranged on the front and rear sides of the pantograph mechanism 7, and the upper and lower ends thereof are the vertical members. A vertical decorative member 38 inserted slidably in the vertical direction into the connecting members 14 and 15 on both upper and lower ends of the frame members 6 and 53, and the inclined links 11 on both left and right sides of the vertical frame members 6 and 53. It is fixed to 12 and the respective decorative member 38 so that the distance between the middle portion in the vertical direction is narrowed during contraction spread upon extension of the pantograph mechanism 7 in conjunction with the stretch right and left of the decorative member 38 of the pantograph mechanism 7 Engagement is slidable in the longitudinal direction The tool 40 is provided.
[0006]

Note that the fixing portion 36 is omitted in FIG. 5 for simplification of the drawing.
[0015]
As shown in FIG. 7, the inner wall 29 of each connecting member main body 27 has openings 37 at four corners. In the opening 37 of the connecting member main body 27 fixed to the upper end of the vertical beam 13, the upper end portion of the decorative member 38 made of a mold having a substantially U-shaped cross section is inserted so as to be slidable in the longitudinal direction of the decorative member 38. In the opening 37 of the connecting member main body 27 fixed to the lower end of the crosspiece 13, the lower end portion of the decorative member 38 is inserted so as to be slidable in the longitudinal direction. With this configuration, the decorative member 38 extends in the vertical direction along the vertical rail 13 and is positioned on both the left and right sides with respect to the vertical frame member 6. The opening 37 of each connecting member body 27 does not necessarily have to be provided separately, and the two openings 37, 37 at both ends of the connecting member body 27 are made into one, and between the two decorative members 38 inserted therein. An elastic body such as rubber may be attached to the gap.
[0016]
The decorative member 38 is a light metal mold material such as aluminum, and the whole has elasticity, and an inner folded portion 39 is formed at both ends. The decorative member 38 is a cross-sectional view showing a state in which the decorative member 38 is attached to the connecting member 14 as the overall length is slightly shorter than the inner dimension between the outer surface walls 30 of the pair of connecting member main bodies 27 facing vertically. As shown in b), only in the upper connecting member 14, a gap is formed between the outer wall 30 of the connecting member main body 27 and the end surface of the decorative member 38.
[0017]
Each decorative member 38 is connected to each of the inclined links 11 and 12 by an engagement tool 40 at a position separated from the fixed pivot 19 by a predetermined distance (FIG. 1). This connecting position is a position where the decorative member 38 straightened between the connecting members 14 and 15 intersects the inclined links 11 and 12 when the gate body 3 is contracted. At this position, the decorative member 38 and the inclined link are joined. In order to connect 11 and 12, a pin made of a round pipe is used as the engagement tool 40 (FIG. 5).
[0018]
One end of the engaging tool 40 is fixed to the inner side walls of the inclined links 11 and 12 formed of square pipes by a rivet 41, and the other end is bent from the folded portion 39 of the decorative member 38 to the U-shaped curved portion. And is slidable with respect to the decorative member 38. In the embodiment, since the decorative member 38 is slidable with respect to the connecting members 14 and 15, the engaging tool 40 and the decorative member 38 may be configured not to slide. In addition, the member that connects the decorative member 38 and the inclined links 11 and 12 is not limited to a pin-shaped member such as a pipe, but may be appropriately selected and used.
[0019]
Next, an operation for opening and closing the telescopic gate of this embodiment will be described. When the gate body 3 is contracted from the state of FIG. 1, the handle 9 may be pushed toward the suspension side column 1. Then, in FIG. 1, the intervals between the vertical frame members 6 are narrowed while the right-upward inclined links 11 are counterclockwise about the fixed pivot 19 and the left-upward inclined links 12 are rotated clockwise. It can be shrunk to a state. When the gate is contracted in this way, the engaging tool 40 connecting the decorative member 38 and the inclined links 11 and 12 is fixed to the fixed pivots 19 as the inclined links 11 and 12 are tilted. When the horizontal distance from the pivot 19 decreases in the direction shown in FIG. 3, the decorative members 38 extend straight along the vertical rails 13.
[0020]
Conversely, when the gate body 3 is extended from the state shown in FIG. 3, the handle 9 may be pulled toward the door-holding column 2, and each inclined link 11, 12 causes the gate body 3 to contract. The interval between the vertical frame members 6 increases while tilting in the opposite direction. If the locking device is locked when the door stop side end frame 4 reaches the door stop side column 2, the doorway of the garage or the like can be closed.
[0021]
When the gate is closed in this way, the decorative member 38 gradually becomes arcuate so that the engaging tool 40 for connection to each inclined link 11, 12 moves away from the fixed pivot 19 in the horizontal direction. It is curved and the degree of bending is greatest when the gate is closed. In order to further increase the degree of bending at this time, the interval between the fixed pivot 19 and the engagement tool 40 may be set wider. In this case, the engagement tool 40 is connected to the inclined links 11 and 12. If it is provided at a position shifted from the center in the width direction, it is possible to make the decorative member 38 straight when the gate body 3 is contracted.
[0022]
When the gate is extended and the doorway is closed, the decorative member 38 is curved, so that the outer dimension of each pair of decorative members 38 located on the left and right with respect to each vertical frame member 6 is widened, and the gate is contracted. However, if this dimension does not change, the opening width of the entrance / exit of the garage or the like is reduced, but when the gate is shrunk in the above embodiment, each decorative member 38 is straightened and its outer dimension is narrowed. There is no inconvenience that the opening width of the doorway becomes small.
[0023]
As described above, the gate according to the present embodiment has the gate that has a gap between the pair of decorative members 38 arranged on both the left and right sides of the vertical frame member 6 in conjunction with the expansion and contraction of the pantograph mechanism 7. It is possible to achieve a visually significant effect that is not seen in a conventional gate, that is, when the door is closed and when it is opened. On the other hand, the vertical beam 13 is arranged between the right upward inclined link 11 and the left upward inclined link 12 of the pantograph mechanism 7 and the decorative member 38 is arranged before and after the pantograph mechanism 7, so that the design member is arbitrarily designed. The decorative member 38 that can be made is more structurally more attractive than the vertical beam 13 that is difficult to change in design, and the design of the entire gate can be improved.
