Abstract

PROBLEM TO BE SOLVED: To close a door only by push-moving and bending first and second stays without push-moving a separate push button by providing an open holding state only by extracting the second stay from the first stay by door opening in an open holder of the door. SOLUTION: A second fixture 2A is installed on the door, and is loosely installed and pivoted on the first stay 1 for loosely installing and pivoting a first fixture 1A installed in a casing, and the second stay 2 expandably loosely fitted to this stay. When closing the door in the arrow A direction, the second saty 2 is extracted from the first stay 1, and a locking object part 2B of the second stay 2 is locked on a locking part 1B of the first stay 1, so that a door opening state is held. When push-moving and bending a central part of the first and second stays 1 and 2 in the arrow B direction by a tiptoe, the locking object part 2B is separated from the locking part 1B, and the door can be closed by sliding the second stay 2 in the arrow C direction. First and second stoppers 1C and 2C of the first and second stays 1 and 2 abut in the door opening state, so that the second stay 2 does not slip out of the first stay 1.

Description

【０００１】
【発明の属する技術分野】
本発明は扉や蓋などの開閉部材を、筐体とか床面、天上面などに蝶着することで開閉自在なるよう取り付けるに際し、当該開閉部材を開放状態に保持することで、強風とかドアクローザによって不本意に閉扉することで事故を起こしてしまったり、物の出入作業に支障を来すとか、換気が不充分となること等を防止するため、扉と筐体との間などに連枢状態となるよう取り付けて使用される開閉部材の開放保持具に関する。
【０００２】
【従来の技術】
【特許文献１】実公昭５８−１７１００号
【特許文献２】実公昭４４−１５６１０号
【０００３】
上記特許文献１には、本願の図５に引用した通り、筐体ａにあって支点軸ｂにより枢支したステーｃには長孔ｄを穿設しておき、筐体ａに対してヒンジｅを介して開閉自在なるように枢支した扉ｆには、上記の長孔ｄに嵌挿した保持軸ｇが固設されるようにした扉等の開放保持具を開示している。そして扉ｆの開成状態で保持軸ｇにおける図示されていない大径部が長孔ｄの先端側に形成された大径孔ｈに係嵌することで、当該開成状態が保持されるようになっている。
しかも当該公知の文献によるときは、上記の如き作用効果を発揮させるため、上記の保持軸ｇに前記大径部とか小径部そしてコイルスプリングなどを付帯させねばならず、前掲支点軸ｂにも複数のコイルスプリングを内設しなければならないことから、多数の部品点数が不可欠となり、かつその製作にも労力を費やさねばならず従って高価なものとなってしまうのはもちろん、当該扉ｆの開成保持状態を解除しようとするときには保持軸ｇをコイルスプリングの弾力に抗して押し込まねばならないことから、その操作性の点でも満足すべきものとなっていない。
【０００４】
さらに特許文献２に開示の伸縮杆なるものも、図示しないが固定杆の取付金具を筐体等に取付け、固定杆に伸縮自在なるよう嵌入した摺動杆の結合金具を扉側に取着し、固定杆から摺動杆が延出された開扉状態にあって、固定杆と摺動杆にわたって被装されたプッシュボタンがその圧縮発条により押圧されることで、プッシュボタンに設けられている錠止杆が、固定杆と摺動杆をロック状態に保持するようにしている。
そして、このロック状態を解除したいときは前記文献と同様に押入操作することで、固定杆内に摺動杆が嵌入自在となり、これにより閉扉動が可能となる。
従って、何れにせよ、この場合にもプッシュボタンには圧縮発条とか錠止杆が必要となり、このため特許文献１と同じくプッシュボタンには各種の部品を組み込まねばならず、特定位置のプッシュボタンを押入しなければならないので操作性についても改善されたものとなってはいない。
【０００５】
【発明が解決しようとする課題】
本願発明は上記従来技術の難点を解消して、複雑な構成をもたせた前掲保持軸とか支点軸そしてプッシュボタン等の部材を全く付加することなしに、開閉部材の開放保持具における扉等の開放保持と、その解除とを実現させ得るようにしようとするのがその着想である。
そして請求項１によるときはまず第１、第２ステーを筐体や扉などに取着するための第１、第２取着用具は単に回動自在であるだけでなしに、がたつきをもたせて遊装枢支させるのであり、さらに第１、第２ステーには別途前記のプッシュボタンの如き部材を全く付帯させることなしに、第１ステー自体の加工により適所に係止部と第１ストッパを形成し、第２ステーについてもその加工によって適所に被係止部と第２ストッパを設定するだけの極めて簡潔な構成にて、開閉部材の解放保持機能を発揮可能にしようとするのが第１の目的である。
【０００６】
さらに請求項１では第１ステーに対し伸縮自在なるよう収納された第２ステーが、常に一直線上を摺動するのではなく遊嵌状態によりもたせた、がたつきを留保して摺動可能なるよう第１、第２ステーを連装状態とすることにより、当該第１、第２ステーが揺動可能であると共に、第１ステーに対する第２ステーの摺動が円滑に行われることを保証しようとするのが第２の目的である。
【０００７】
しかも当該請求項１では扉等を閉止状態から開成して行く際、前記の第２ステーに設けた被係止部が第１ステーの係止部に係止状態となることで、扉等の開放保持状態が確保されると共に、万一第２ステーが第１ステーから急速に引出されたような場合でも、第１ストッパに第２ストッパが係当することで第１ステーから第２ステーが脱出されてしまうといった不測の支障を生じさせないようにするのが第３の目的である。
【０００８】
また同上発明では上記のようにして開扉状態が保持されている際、これを閉扉可能にしようとする際には、もちろん別途プッシュボタンを押動するといった操作を行うことなく、開扉状態下で第１、第２ステーが重装されている略長手方向中央箇所を一方向へ押動させれば、第１、第２ステーは直線的な状態から、屈曲状態に変動することにより、第１ステーの係止部から第２ステーの被係止部が離脱可能なるよう構成することにより、例えば上記した第１、第２ステーの長手方向中央箇所を足先にて押し上げるといった簡易迅速な挙動だけで閉扉保持の状態を解除可能とすることができるようにし、その操作性を飛躍的に向上しようとするのが第４の目的である。
【０００９】
そして前記の通り第１、第２ストッパを夫々第１、第２ステーに設けることによって、第１ステーの係止部から第２ステーの被係止部を前記の通り足先などで離脱させた際、第１ストッパがなければ第２ステーが第１ステーから抜け出してしまうといった問題を解消し得ると共に、第２ストッパがなければ第２ステーが第１ステーに挟着状態となることで第１、第２ステーの縮動操作が不能または困難となるといった問題の惹起をも絶滅しようとするのが第５の目的である。
【００１０】
次に請求項２にあっては、上記した請求項１における第１、第２ステーを夫々第１、第２横向板部と一対の第１、第２側板部により形成し、さらに請求項１における第１ステーに設けた係止部を係止通孔により形成すると共に、第２ステーの被係止部を係止突起により形成すると共に、第１、第２ストッパの設定位置を特定することによって、前記請求項１と同じ効果をより確実に達成しようとするのが、その目的である。
【００１１】
【課題を解決するための手段】
本発明は、上記の目的を達成するため、請求項１にあっては第１ステーと第２ステーとからなり、第１ステーには遊装枢支された第１取着用具と係止部そして第１ストッパが設けられ、第２ステーには遊装枢支された第２取着用具と被係止部そして第２ストッパが設けられ、上記第１ステーに第２ステーを伸縮自在なるよう遊嵌状態にて摺動可能に連装し、第１ステーに縮小状態で遊嵌の第２ステーを引出して伸長状態とすることにより、第１ステーの係止部に第２ステーの被係止部を係脱自在に係止することで、第１ストッパと第２ストッパとを隣装状態にて第１、第２ステーの伸長状態を保持自在となし、当該第１、第２ステーの上記伸長係止状態にあって、第１、第２ステーが屈曲状態となる方向へ押動操作されることで、前記第１ステーの係止部から第２ステーの被係止部を離脱することにより、第１ステーと第２ステーとの縮小状態への移行を可能となし、かつ上記した第１ステーの係止部から第２ステーの被係止部を離脱した際、前記した第１ストッパに対する第２ストッパの係当により、第１ステーから第２ステーが抜出したり、第２ステーが第１ステーに挟着状態となって、第１、第２ステーの縮動が阻害されることのないようにしたことを特徴とする開閉部材の開放保持具を提供しようとしている。
【００１２】
次に請求項２に係る開閉部材の開放保持具にあっては上記請求項１に係る実施態様を明示したもので、第１横向板部と一対の第１側板部とにより樋状に形成の第１ステーと、第２横向板部と一対の第２側板部とにより樋状に形成の第２ステーとからなり、第１ステーには第１横向板部の一端側に遊装枢支の第１取着用具が外装されると共に、他端寄りには係止部としての係止通孔を穿設し、かつ当該他端側には上記一対の第１側板部の第１端縁側から第１ストッパを内設し、第２ステーには第２横向板部の一端側に遊装枢支の第２取着用具が外設されると共に、第２横向板部から立設された一対の第２側板部の第２端縁側から第２ステーの被係止部である第２係嵌突起を延設し、かつ上記第２横向板部から第２ストッパを外設し、上記第１ステーにはその第１横向板部と第２横向板部とが離間対向状態で長手方向へ伸縮自在なるよう遊嵌状態にて摺動可能に連装され、第１ステーに縮小状態で遊嵌の第２ステーを引出して伸長状態とすることにより、第１ステーの係止部である係止通孔に第２ステーの被係止部である第２係嵌突起を係脱自在に係止することで、第１ストッパと第２ストッパとを隣装状態として第１、第２ステーの伸長状態を保持自在となし、当該第１、第２ステーの上記伸長係止状態にあって、第１、第２ステーが屈曲状態となる方向へ押動操作されることで、前記係止部である係止通孔から第２ステーの被係止部である係嵌突起を離脱することにより、第１ステーと第２ステーとの縮小状態への移行を可能となし、かつ上記した第１ステーの上記係止通孔から第２ステーの前記係嵌突起を離脱した際、第１ストッパに対する第２ストッパの係当により第１ステーから第２ステーが抜出したり、第２ステーが第１ステーに挟着状態となって、第１、第２ステーの縮動が阻害されることのないようにしたことをその内容としている。
【００１３】
【発明の実施の形態】
本願請求項１の発明について図１を参照して以下詳記すると、第１ステーと第２ステーとによって構成されており、第１ステー１には図面の右端側から順次第１取着用具１Ａと係止部１Ｂそして第１ストッパ１Ｃが設けられている。
ここで上記第１取着用具１Ａなるものは既知の如く実際上筐体等に、その第１取着座板１ａが第１取着用孔１ｂに図示されていない取着螺子により取着される。そして当該第１取着座板１ａには第１抜止枢支軸１ｃによって、がたつきを持たせるようにして遊装枢支されており、従って第１ステー１は第１取着用具１Ａに対し旋回自在にして、かつ図面にあって上下方向などにも揺動が許容されるよう連装されている。
【００１４】
そして第２ステー２には同図の左端側から順次第２取着用具２Ａと第２ストッパ２Ｃそして被係止部２Ｂが設けられている。
ここで上記の第２取着用具２Ａなるものは既知の如く実際上扉などに対し、その第２取着用孔２ｂに図示されていない取着螺子により取着されることになるのであり、前記第１取着用具１Ａの場合と同様にして第２抜止枢支軸２Ｃにより、がたつきを持たせるようにして遊装枢支されており、従って第２ステー２も第１ステー１と同様に第２取着用具２Ａに対し旋回自在で、しかも図面にあって上下方向などに揺動が許容されるよう連装されることになる。
【００１５】
さらに請求項１では上記の如き第１ステー１に第２ステー２を伸縮自在なるよう遊嵌状態すなわち、第１、第２ステー１、２間に隙間を持たせて揺動可能なるよう連装するのであり、第１ステー１に縮小状態で遊嵌した第２ステー２を図１（Ａ）の如く矢印Ａ方向へ引き出すことで伸長状態となるようにする。すなわち扉等を開成することにより、第１ステー１にあって設けてある係止部１Ｂに、第２ステー２に形成の被係止部２Ｂが係止されるに至れば、同図（Ｂ）の如く、第１ストッパ１Ｃと第２ストッパ２Ｃとが接触または近接による隣装状態にて、第１、第２ステー１、２の伸長状態、すなわち開扉状態が保持されるに至る。
【００１６】
そこで上記の第１、第２ステー１、２の伸長係止状態にあって図１（Ｃ）に開示の如く矢印Ｂ方向へ具体的には足先などによって、第１、第２ステー１、２が図示例では上向きに屈曲状態となるように、第１、第２ステー１、２の重装状態となっている中央箇所を押動操作することで、第１ステー１の係止部１Ｂから第２ステー２の被係嵌部２Ｂが離脱され得るように構成するのである。
【００１７】
かくして図１（Ｄ）に開示の通り第１ステー１と第２ステー２との縮小状態への矢印Ｃで示す方向への移行が許容されることになるのである。
しかも請求項１にあっては前記した通り図１（Ｂ）の如く第１、第２ステー１、２が伸長状態となったとき、第１ストッパ１Ｃと第２ストッパ２Ｃとが隣装状態となっていることから、図４（Ｂ）に提示の如く第１ストッパ１Ｃが設けられていないときには、係止部１Ｂから被係止部２Ｂが離脱した際に、第２ステー２が開扉方向への矢印Ｄ方向への力を受けることで、第２ステー２は第１ステー１から抜け出してしまうこととなるが、本発明ではこのような不本意な動きを完全に阻止できることになる。
【００１８】
さらにまた、図４（Ａ）に開示の如く第２ストッパ２Ｃが設けられていないような場合にあっては、第２ステー２が第１ステー１から引き出されようとしたとき、第２ステー２が第１ステー１に対して、かじりつくような挟着状態となってしまい、これより第２ステー２を第１ステー１内へ縮動しようとしても摺動不能となり、この結果扉の閉成操作が不能または困難となってしまうことにも解消される。
【００１９】
次に請求項２について記載するが、ここでは請求項１についての一実施態様を開示しており、これを前記した図１、図４だけではなく、さらに図２と図３をも参照しながら以下説示する。
まず第１ステー１は、第１横向板部１ｄと一対の第１側板部１ｅとによって樋状に形成されており、第２ステー２も同様にして第２横向板部２ｄと一対の第２側板部２ｅとによって樋状に形成されている。
そして第１ステー１には第１横向板部１ｄの一端側に前説の通り第１取着用具１Ａが遊装枢支され、他端寄りには前記した係止部１Ｂとしての係止通孔１ｆが穿設されている。
そして図示の係止通孔１ｆは、特に図２（Ｄ）により理解される通り、一対の第１側板部１ｅと第１横向板部１ｄとにより形成された両コーナ箇所にあって穿設されるようにし、これに前記第２ステー２の被係止部２Ｂが係脱自在なるよう構成されている。
さらに第１ステー１の他端側には上記一対の第１側板部１ｅにおける第１端縁側１ｇから前記の第１ストッパ１Ｃが直交状に曲折されて内向きに突設されている。
【００２０】
次に第２ステー２には第２横向板部２ｄの一端側にあって、前説の第２取着用具２Ａが遊装枢支され、第２横向板部２ｄから立設された一対の第２側板部２ｅにおける第２端縁側２ｇから、第２ステー２における被係止部２Ｂとしての係嵌突起２ｆが延設され、さらに第２横向板部２ｄからは第２ストッパ２Ｃが外向きに延出して立設されている。
そして第１ステー１と第２ステー２は、夫々の第１、第２横向板部１ｄ、２ｄとが、離間対向の状態で長手方向へ伸縮自在となるよう遊嵌状態にて摺動可能なるよう連装されている。
【００２１】
かくして第１ステー１に縮小状態で遊嵌されている第２ステー２を引き出して伸長状態とすれば、第１ステー１の係止部１Ｂである前記係止通孔１ｆに、第２ステー２の被係止部２Ｂである係止突起２ｆを係脱自在なるよう係止することで、第１、第２ストッパ１Ｃ、２Ｃを請求項１につき説示の如く隣装状態として、第１、第２ステー１、２の伸長状態を保持自在とすることができる。
さらに請求項２では上記伸長状態にあって足先などによって前記の如く第１、第２ステー１、２を屈曲状態となるよう押動操作することにより、係止通孔１ｆから第２ステー２の係嵌突起２ｆを離脱することができ、これにより第１ステー１を第２ステー２内に進入させて閉扉させるといったことが可能となり、第１、第２ステー１、２の縮小状態への移行が可能となる。
【００２２】
なお請求項２についても、請求項１につき説示の如く第１ステー１の係止通孔１ｆから第２ステー２の係止突起２ｆを離脱した際、第１、第２ストッパ１Ｃ、２Ｃの係当で第１ステー１から第２ステー２が抜出したり、第２ステー２が第１ステー１に挟着状態となって第１、第２ステー１、２の縮動操作が困難または不能となってしまうこともない。
【００２３】
【発明の効果】
本願発明は以上のようにして構成されているから、請求項１によるときは、第１、第２ステーによる第１、第２取着用具を遊嵌枢支させ、第１ステー自体に係止部、第１ストッパを形成し、第２ステーにもその加工で被係止部と第２ストッパを設定するだけで、別途複雑な構成のプッシュボタンなどを付帯させる必要がないため、極めて簡潔安価な製作が可能となり、その耐久性についても高い信頼性を保有させることができる。
【００２４】
さらに、第１、第２ステーの連装構成が、単に一直線上を摺動して伸縮自在となるようにするのではなしに、両ステーを遊嵌状態として、がたつきを許容するようにしたので第１、第２ステーは揺動可能となるだけでなく、第１ステーに対する第２ステーの摺動も円滑に行い得ることになる。
【００２５】
また扉の開成により第２ステーの被係止部が第１ステーの係止部に係止されるだけで、開扉状態の信頼性ある保持が確保され、かつこの際第２ステーの引出力が大となっても第１、第２ストッパの係当でこれを阻止でき、第２ステーが第１ステーから脱出してしまうといった不測の支障を高い信頼性をもって阻止することができる。
【００２６】
さらに重要なことは、開扉状態で伸長状態の第１、第２ステーにおける中央箇所を、簡易迅速に行い得る押動操作だけで両ステーを屈曲状態に変動自在とし、当該変動によって係止部から被係止部を離脱自在なるよう構成したので単にプッシュボタンなどの別部材が一切不要となるだけでなく、開閉保持状態の解除に際しての操作性を飛躍的に向上することができる。
【００２７】
そして前記の如く第１、第２ステーの適所に第１、第２ストッパを設けるようにしたことから、前記の通り第２ステーが第１ステーから抜出する心配がないだけでなく、第２ステーが第１ステーにあって挟着状態となってしまい、第１、第２ステーの縮動が阻害されるといった虞も解消することができる。
【００２８】
次に請求項２にあっては、第１、第２ステーを第１、第２横向板部と一対の第１、第２側板部で構成したり、第１ステーの係止部を係止通孔により、そして第２ステーの被係止部を係止突起によって適切に形成し、かつ第１、第２ストッパの設定位置を特定するようにしたことから、上記した請求項１の多岐にわたる諸効果につき、その信頼性を確保することが可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention, when attaching the opening and closing members such as doors and lids so that they can be opened and closed by hinged to the housing, floor surface, top surface, etc., by holding the opening and closing members in an open state, by strong wind or door closer In order to prevent accidents due to unintentional closing of the door, hindering entry / exit work, insufficient ventilation, etc., it is pivoted between the door and the housing etc. The present invention relates to an open / close holder for an opening / closing member which is used by being attached so as to be as follows.
[0002]
[Prior art]
[Patent Document 1] Japanese Utility Model Publication No. 58-17100 [Patent Document 2] Japanese Utility Model Publication No. 44-15610 [0003]
In the above-mentioned Patent Document 1, as shown in FIG. 5 of the present application, a long hole d is formed in a stay c which is provided in a housing a and pivotally supported by a fulcrum shaft b, and a hinge is provided for the housing a. An open holder such as a door in which a holding shaft g fitted in the long hole d is fixed to a door f pivotally supported so as to be openable and closable via e is disclosed. When the door f is in the opened state, the large-diameter portion (not shown) of the holding shaft g is engaged with the large-diameter hole h formed at the tip end of the long hole d, so that the opened state is maintained. ing.
In addition, according to the known document, in order to exert the above-described effects, the large-diameter portion, the small-diameter portion, the coil spring, and the like must be attached to the holding shaft g. The number of parts is indispensable because the coil spring must be installed inside the vehicle, and the production of the coil spring requires a lot of effort. When the state is to be released, the holding shaft g must be pushed in against the elasticity of the coil spring, so that the operability is not satisfactory.
[0004]
In addition, although not shown, a telescopic rod disclosed in Patent Document 2 is also provided with a fixing rod mounting bracket (not shown) attached to a housing or the like, and a sliding rod coupling metal fitting that is telescopically fitted to the fixed rod is attached to the door side. In a door-open state in which the sliding rod extends from the fixed rod, the push button mounted on the fixed rod and the sliding rod is provided on the push button by being pressed by the compression spring. A locking rod holds the fixed rod and the sliding rod in a locked state.
When it is desired to release the locked state, the sliding operation is performed in the same manner as in the above-mentioned literature, whereby the sliding rod can be freely inserted into the fixed rod, thereby enabling the door closing movement.
Therefore, in any case, in this case, the push button also needs a compression spring or a locking rod. For this reason, as in Patent Document 1, various components must be incorporated into the push button. The operability has not been improved because it must be pushed in.
[0005]
[Problems to be solved by the invention]
The present invention solves the above-mentioned drawbacks of the prior art, and opens the door and the like in the opening / closing member of the opening / closing member without adding any member such as the holding shaft, the fulcrum shaft, and the push button having a complicated structure. The idea is to make it possible to achieve the holding and the release.
According to the first aspect, first, the first and second attachments for attaching the first and second stays to the housing or the door are not only rotatable but also play. The first stay and the second stay are not provided with any member such as the push button at all, and the first stay itself is processed by the first stay itself so that the engaging portion and the first stay can be pivotally supported. A stopper is formed, and the second stay is designed to be able to exhibit the function of releasing and holding the opening / closing member with an extremely simple configuration in which the locked portion and the second stopper are set in place by processing. This is the first purpose.
[0006]
Further, in the first aspect, the second stay accommodated so as to be expandable and contractible with respect to the first stay is not always slid on a straight line but is provided with a loose fit state. By setting the first and second stays in the continuous state as described above, the first and second stays can swing, and the sliding of the second stay with respect to the first stay can be performed smoothly. This is the second purpose.
[0007]
Further, in the first aspect, when the door or the like is opened from the closed state, the locked portion provided on the second stay is locked to the locking portion of the first stay, so that the door or the like can be opened. In addition to ensuring the open holding state, even in the event that the second stay is rapidly pulled out of the first stay, the second stay is engaged with the first stopper so that the first stay and the second stay can be moved. A third object is to prevent an unexpected trouble such as escape.
[0008]
Further, in the above-mentioned invention, when the door is kept open as described above, when the door is to be able to be closed, of course, without performing an operation such as pushing a separate push button, the door is not opened. If the central portion in the longitudinal direction where the first and second stays are overlapped is pushed in one direction, the first and second stays change from a linear state to a bent state. By configuring the locked portion of the second stay to be detachable from the locking portion of the first stay, for example, a simple and quick behavior such as pushing up the central portion in the longitudinal direction of the first and second stays with the toes. A fourth object is to make it possible to release the state of holding the door closed only by itself and to dramatically improve the operability.
[0009]
By providing the first and second stoppers on the first and second stays, respectively, as described above, the locked portion of the second stay was detached from the locking portion of the first stay with the toes as described above. In this case, it is possible to solve the problem that the second stay comes off from the first stay if there is no first stopper, and if the second stopper does not exist, the second stay is sandwiched between the first stays so that the first stay is held. It is a fifth object of the present invention to eliminate the occurrence of problems such as the inoperability or difficulty of the retracting operation of the second stay.
[0010]
Next, in a second aspect, the first and second stays in the first aspect are formed by a first and a second horizontal plate portion and a pair of the first and second side plate portions, respectively. The locking portion provided on the first stay is formed by a locking through hole, the locked portion of the second stay is formed by a locking projection, and the setting positions of the first and second stoppers are specified. It is an object of the present invention to more reliably achieve the same effect as the first aspect.

A first stopper is provided, a second stay is provided with a second mounting tool pivotally supported, a locked portion, and a second stopper, so that the first stay can extend and retract the second stay. The second stay is loosely fitted to the first stay in a contracted state, and the second stay is pulled out to an extended state in a reduced state. The first and second stoppers can be freely held in an extended state by placing the first stopper and the second stopper adjacent to each other by engaging and disengaging the portions, and the first and second stays can be held in the extended state. When the first and second stays are pushed and pushed in a direction in which the first and second stays are in a bent state in the extended and locked state, the first stay is moved. By disengaging the locked portion of the second stay from the locking portion of the first stay, it is possible to shift the first stay and the second stay to the reduced state, and from the locking portion of the first stay. When the locked portion of the second stay is disengaged, the second stay is engaged with the first stopper, so that the second stay is pulled out of the first stay or the second stay is pinched by the first stay. Thus, an attempt is made to provide an opening and closing member for the opening / closing member, wherein the first and second stays are not prevented from contracting.
[0012]
Next, in the open-holding member for the opening / closing member according to claim 2, the embodiment according to claim 1 is specified, and the gutter shape is formed by the first horizontal plate portion and the pair of first side plate portions. A first stay, a second stay formed in a gutter shape by a second transverse plate portion and a pair of second side plate portions, and the first stay has a play support pivot at one end side of the first transverse plate portion. The first attachment is externally provided, and a locking through hole as a locking portion is formed near the other end, and the other end side is formed from the first edge side of the pair of first side plate portions. A first stopper is provided therein, and a second stay is provided on one end side of the second lateral plate portion on the second stay, and a second mounting member for play support is externally provided, and a pair of standing members are provided upright from the second lateral plate portion.

BEST MODE FOR CARRYING OUT THE INVENTION
The invention of claim 1 of the present application will be described in detail below with reference to FIG. 1. The first stay 1 is constituted by a first stay and a second stay. And a locking portion 1B and a first stopper 1C.
Here, the first attachment 1A is actually attached to a housing or the like as is known, with the first attachment seat plate 1a being attached to the first attachment hole 1b by an attachment screw (not shown). The first mounting seat plate 1a is swingably supported by the first retaining pivot shaft 1c so as to have a play, so that the first stay 1 is supported by the first mounting device 1A. It is pivotally mounted so as to be swingable and swingable in the vertical direction in the drawing.
[0014]
The second stay 2 is provided with a second mounting tool 2A, a second stopper 2C, and a locked portion 2B sequentially from the left end side in FIG.
Here, the above-mentioned second attaching tool 2A is actually attached to a door or the like by an attaching screw (not shown) in the second attaching hole 2b, as is known. As in the case of the first mounting tool 1A, the second stay 2 is pivotally supported by the second retaining pivot 2C so as to have a play. Therefore, the second stay 2 is also similar to the first stay 1. In addition, the second attachment 2A is pivotally connected to the second attachment 2A so as to be swingable in a vertical direction in the drawing.
[0015]
Further, in the first aspect, the first stay 1 is connected to the first stay 1 in a loosely fitted state so that the second stay 2 can expand and contract, that is, the first stay 1 and the second stay 1 and 2 are swingably mounted with a gap therebetween. The second stay 2 loosely fitted to the first stay 1 in the contracted state is drawn in the direction of arrow A as shown in FIG. That is, if the locked portion 2B formed on the second stay 2 is locked by the locking portion 1B provided on the first stay 1 by opening the door or the like, FIG. ), The extended state of the first and second stays 1 and 2, that is, the open state of the door, is maintained in a state in which the first stopper 1 C and the second stopper 2 C are adjacent to each other due to contact or proximity.
[0016]
Therefore, in the extended and locked state of the first and second stays 1 and 2, the first and second stays 1 and 2 are moved in the direction of arrow B as shown in FIG. In the illustrated example, the locking portion 1B of the first stay 1 is operated by pushing the central portion where the first and second stays 1 and 2 are in the heavy loading state so that the second stay 2 is bent upward. Thus, the engaged portion 2B of the second stay 2 can be detached from the second stay 2.
[0017]
Thus, as shown in FIG. 1 (D), the first stay 1 and the second stay 2 are allowed to move to the contracted state in the direction indicated by the arrow C.
Moreover, in the first aspect, when the first and second stays 1 and 2 are in the extended state as shown in FIG. 1B, the first stopper 1C and the second stopper 2C are in the adjacent state. Therefore, when the first stopper 1C is not provided as shown in FIG. 4B, when the locked portion 2B is detached from the locking portion 1B, the second stay 2 moves in the door opening direction. By receiving a force in the direction of arrow D, the second stay 2 comes off the first stay 1, but in the present invention, such an undesired movement can be completely prevented.
[0018]
Furthermore, in the case where the second stopper 2C is not provided as disclosed in FIG. 4A, when the second stay 2 is pulled out from the first stay 1, the second stay 2 Is in a state of being stuck to the first stay 1, so that the second stay 2 cannot slide even if it is contracted into the first stay 1. As a result, the door closing operation is performed. Is also impossible or difficult.
[0019]
Next, claim 2 will be described. Here, an embodiment of claim 1 is disclosed. This is described not only with reference to FIGS. 1 and 4 described above but also with reference to FIGS. 2 and 3. This is explained below.
First, the first stay 1 is formed in a gutter shape by a first horizontal plate portion 1d and a pair of first side plate portions 1e, and the second stay 2 is similarly formed with a second horizontal plate portion 2d and a pair of second second plate portions. A gutter shape is formed by the side plate portion 2e.
As described above, the first stay 1 is provided with a first mounting tool 1A at one end of the first horizontal plate portion 1d as a play-supporting pivot, and a locking through hole serving as the locking portion 1B near the other end. If is drilled.
As shown in FIG. 2D, the illustrated locking through-hole 1f is formed at both corners formed by the pair of first side plate portions 1e and the first horizontal plate portion 1d. The locked portion 2B of the second stay 2 is configured to be freely disengageable.
Further, on the other end side of the first stay 1, the first stopper 1C is bent orthogonally from the first end side 1g of the pair of first side plate portions 1e and protrudes inward.
[0020]
Next, the second stay 2 is provided at one end side of the second horizontal plate 2d, and the second attachment 2A described above is freely pivotally supported, and a pair of second mounting members erected from the second horizontal plate 2d. An engagement projection 2f as a locked portion 2B of the second stay 2 extends from the second edge 2g of the second side plate 2e, and a second stopper 2C extends outward from the second lateral plate 2d. It is extended and erected.
The first stay 1 and the second stay 2 can be slid in a loosely fit state such that the first and second horizontal plate portions 1d and 2d can be extended and contracted in the longitudinal direction in a state of being opposed to each other. It is connected like so.
[0021]
Thus, when the second stay 2 loosely fitted to the first stay 1 is pulled out to be in the extended state, the second stay 2 is inserted into the locking through hole 1f which is the locking portion 1B of the first stay 1. The first and second stoppers 1C and 2C are brought into the side-by-side state as shown in claim 1 by locking the locking projection 2f, which is the locked portion 2B, so as to be freely detachable. The extended state of the two stays 1 and 2 can be freely held.
In the second aspect, the first and second stays 1 and 2 are pushed by the feet or the like so as to be bent as described above in the extended state, so that the second stay 2 is moved from the locking through hole 1f. Can be disengaged, whereby the first stay 1 can enter the second stay 2 to close the door, and the first and second stays 1 and 2 can be reduced to a reduced state. Migration is possible.
[0022]
In the case of claim 2 as well, when the locking projection 2f of the second stay 2 is detached from the locking through hole 1f of the first stay 1 as described in claim 1, the first and second stoppers 1C and 2C are engaged. At this time, the second stay 2 is pulled out from the first stay 1 or the second stay 2 is sandwiched between the first stays 1 to make it difficult or impossible to contract the first and second stays 1 and 2. It doesn't even happen.
[0023]
【The invention's effect】
Since the present invention is constructed as described above, according to the first aspect, the first and second mounting tools by the first and second stays are freely fitted and pivotally supported, and are locked to the first stay itself. Part, the first stopper, and the locked part and the second stopper are also set in the second stay by the processing, and it is not necessary to attach a push button or the like having a complicated structure separately. Manufacturing is possible, and high durability can be maintained.
[0024]
Furthermore, since the connecting structure of the first and second stays is not merely made to slide on a straight line so as to be able to expand and contract, both stays are made to be in a loosely fitted state to allow rattling. The first and second stays can not only swing, but also can smoothly slide the second stay with respect to the first stay.
[0025]
Further, only by the locking of the locked portion of the second stay by the locking portion of the first stay by opening of the door, a reliable holding of the opened state is ensured, and at this time, the pulling out of the second stay is performed. Can be prevented by engagement of the first and second stoppers, and an unexpected trouble such that the second stay escapes from the first stay can be prevented with high reliability.
[0026]
More importantly, the center portions of the first and second stays in the extended state in the opened state can be freely changed to the bent state only by a pushing operation that can be performed simply and quickly. Since the locked portion is configured to be detachable from the device, not only a separate member such as a push button is not required at all, but also the operability when releasing the open / close holding state can be dramatically improved.
[0027]
Since the first and second stoppers are provided at appropriate positions of the first and second stays as described above, not only is there no need to worry about the second stay being pulled out of the first stay as described above, but also from the second stop. It is also possible to eliminate the risk that the stay is in the pinched state when the stay is in the first stay and the contraction of the first and second stays is hindered.
[0028]
Next, in claim 2, the first and second stays are composed of the first and second horizontal plate portions and a pair of first and second side plate portions, or the locking portions of the first stay are locked. The above-mentioned claim 1 is diversified because the locked portion of the second stay is appropriately formed by the through-hole and the locking projection, and the set position of the first and second stoppers is specified. It is possible to secure the reliability of various effects.
