Description

本発明は扉を回動自在に保持するヒンジ装置に関するものである。   The present invention relates to a hinge device that rotatably holds a door.

従来から、枠体に扉を回動自在に保持するヒンジ装置としては丁番やピボットヒンジが知られており、どちらにおいても扉の開く側に軸芯位置を持ち出すことにより扉の１８０°の回転を可能にするものがほとんどである。したがって、当然軸芯部分は扉面から突出することになり、デザイン性においてはあまりよくなく、特に室内ドアなどでは扉面からの突起物になるため幼児が頭部をぶつける等の危険性もある。   Conventionally, hinges and pivot hinges are known as hinge devices that hold the door rotatably on the frame, and in either case, the door can be rotated 180 ° by bringing the axial center position to the door opening side. Most of them make it possible. Therefore, the shaft core part naturally protrudes from the door surface, which is not very good in terms of design. In particular, in the case of an indoor door or the like, there is a risk that an infant may hit the head because it becomes a protrusion from the door surface. .

またフロアヒンジ等の、扉の厚み方向の中心位置に軸芯を有した中心吊のものもあるが、このタイプは基本的に９０°までしか扉を開放できず、また扉の吊元側厚み面と枠体との隙間を大きく取る必要もあり使用用途が制限され一般的にはそれ程多用されていないのが現状である。また、軸芯部分を含む全体を扉と枠体の厚み方向内に内蔵することができる隠し蝶番があり、この隠し蝶番は外観が全く露出しないとともに１８０°の開放も可能である。しかし隠し蝶番は部品点数が非常に多く機構が複雑で高価であると共に、扉を吊り込む際に扉側と枠側に分割できないため吊り込みが困難で、また扉及び枠体への複雑な掘り込みが必要であり、さらには隠し蝶番は機構上強度を得やすい構造にはなっておらず重量扉には向かない等の問題点を有している。   In addition, some types such as floor hinges have a central suspension with an axial center at the center position in the thickness direction of the door, but this type can basically open the door only up to 90 °. Since it is necessary to make a large gap between the surface and the frame, the usage is limited, and in general, it is not so frequently used. Further, there is a hidden hinge that can be incorporated in the thickness direction of the door and the frame, including the shaft core portion. The appearance of the hidden hinge is not exposed at all and can be opened by 180 °. However, the hidden hinge has a very large number of parts, its mechanism is complicated and expensive, and it cannot be divided into the door side and the frame side when hanging the door, so it is difficult to hang it, and complicated digging into the door and frame Furthermore, the concealed hinge has a problem that it is not suitable for heavy doors because it is not structured to easily obtain strength.

またピボットヒンジの形式で扉側プレートと枠側ベースプレートの間にさらに中間プレートを設け、これらの各プレートを２本の回転軸にて連結し、回転軸を持ち出さずに１８０°の開放を可能とした構成のものがあり、この構成においては扉の開閉の際に中間プレートが勝手に回転してしまう逆折れ現象が問題とされてきた。そこでこの逆折れ現象を阻止すると共に規則に従った各プレートの動作を得るものが実開平２−１１９８３や実開平５−７１３８２等に開示されている。   In addition, an intermediate plate is provided between the door-side plate and the frame-side base plate in the form of a pivot hinge, and these plates are connected by two rotating shafts, enabling 180 ° opening without taking out the rotating shaft. In this configuration, the reverse folding phenomenon that the intermediate plate rotates freely when the door is opened and closed has been a problem. Therefore, what prevents the reverse folding phenomenon and obtains the operation of each plate in accordance with the rules is disclosed in Japanese Utility Model Laid-Open No. 2-1983 and Japanese Utility Model Laid-Open No. 5-71382.

しかし実開平２−１１９８３は各ヒンジの動作を規制する機構がボールをばねで凹部分に付勢させる構成であり、常に滑らかに開閉する場合はこのような抵抗の大小で動作を制御できるかもしれないが、急激な力が部分的にかかったときなどでは誤作動が起こることが考えられ、逆折れを完全に阻止することは難しいと想定できる。また実開平５−７１３８２は枠側ベースプレートと中間プレートと扉側プレートの構成にさらに移動部材を設け、枠側ベースプレートと扉側プレートに設けた凹部分に移動部材が出没する動作により中間プレートの動作を制御する構成になっている。したがって移動部材が別途必要であると共に枠側ベースプレートと扉側プレートに円形の回転盤部分を設けてその外周に凹部分が必要になり、形状的にも制限が多いと考えられる。   However, the actual open 2-11983 has a structure in which the mechanism for regulating the operation of each hinge urges the ball to the concave portion with a spring, and when it is always opened and closed smoothly, the operation may be controlled by the magnitude of such resistance. However, it can be assumed that it is difficult to completely prevent the reverse folding when a sudden force is partially applied. Further, the actual open flat 5-71382 further includes a moving member in the structure of the frame side base plate, the intermediate plate, and the door side plate, and the operation of the intermediate plate is caused by the movement of the moving member in and out of the recessed portion provided in the frame side base plate and the door side plate. Is configured to control. Therefore, a separate moving member is required, and a circular turntable portion is provided on the frame-side base plate and the door-side plate, and a concave portion is required on the outer periphery thereof.

また前記実開平２−１１９８３や実開平５−７１３８２は共に家具や収納扉等を前提にしており、枠側ベースプレートと中間プレートと扉側プレートとその他の必要部品を第一回転軸と第二回転軸にて完全に組付けた状態で扉と枠体に装着する構成になっている。したがって扉を持ち上げた状態で保持しながら枠側ベースプレートや扉側プレートをねじ等で固定する必要があり、玄関や室内用の大型の重量を有する扉等での吊り込み作業は非常に困難と考えられる。 Further, the actual open flat 2-11983 and the actual open flat 5-71382 are premised on furniture, storage doors, etc., and the frame side base plate, the intermediate plate, the door side plate, and other necessary parts are used as the first rotation shaft and the second rotation. It is configured to be attached to the door and frame with the shaft fully assembled. Therefore, it is necessary to fix the frame side base plate and the door side plate with screws etc. while holding the door in a lifted state, and it is very difficult to hang it at the entrance or door with a large weight for indoor use. It is done.

そこで本発明者はピボットヒンジタイプで扉側プレートと枠側ベースプレートの間に中間プレートを設け、第一回転軸と第二回転軸にて各プレートを連結した構成で１８０°の開閉を可能とし、かつ中間プレートの逆折れ現象を阻止でき、さらにはヒンジ装置を分割して枠体と扉に別々に装着し、その後両者を嵌め合わせることにより扉を容易に吊り込むことをも可能とした、玄関ドアや室内ドア等の重量扉にも十分対応可能なヒンジ装置を特開２００２−２５０１７１にて提示した。   Therefore, the present inventor is a pivot hinge type, an intermediate plate is provided between the door side plate and the frame side base plate, and the plate can be opened and closed by 180 ° with a configuration in which the plates are connected by the first rotating shaft and the second rotating shaft. In addition, it can prevent reverse folding phenomenon of the intermediate plate, and it is also possible to easily hang the door by dividing the hinge device and attaching it separately to the frame and door, and then fitting them together Japanese Patent Laid-Open No. 2002-250171 presented a hinge device that can sufficiently handle heavy doors such as doors and indoor doors.

このヒンジ装置は所定角度位置までは扉側プレートと中間プレートが重なった状態で第一回転軸を中心に回転し、所定角度位置に達した段階で扉に装着されている扉側プレートのみが第二回転軸を中心としてさらに回転する構成で、このとき中間プレートは係止ピンにより規制されて所定角度位置にて一旦完全に保持されることにより逆折れを防止する機構が設けられている。したがって大きく開放した状態から扉を閉じると、所定角度位置直前までは中間プレートは係止ピンにより保持されて逆折れすることはなく、所定角度位置直前から所定角度位置に到達する微小閉鎖角度間に扉側プレートが係止ピンを解除して中間プレートの閉じる方向への回転を可能にし、その結果所定角度位置からは扉側プレートと中間プレートが重なった状態で扉が閉じる構成になっている。   The hinge device rotates about the first rotation axis with the door side plate and the intermediate plate overlapping until a predetermined angle position, and only the door side plate attached to the door is reached when the predetermined angle position is reached. The mechanism further rotates around the two rotation shafts. At this time, the intermediate plate is regulated by a locking pin, and a mechanism for preventing reverse folding is provided by being completely held at a predetermined angular position. Therefore, when the door is closed from a state where it is largely opened, the intermediate plate is held by the locking pin until immediately before the predetermined angle position and does not reversely bend, but between the minute closing angle that reaches the predetermined angle position immediately before the predetermined angle position. The door side plate releases the locking pin to enable the rotation of the intermediate plate in the closing direction. As a result, the door is closed in a state where the door side plate and the intermediate plate overlap from a predetermined angle position.

しかし上記の構成では中間プレートの逆折れ現象を防止する機構に係止ピンの上下方向の出没動作を採用したため、閉鎖時に扉側プレートの水平方向の回転移動により係止ピン先端を押して上下方向に没する動作を必要とし、この動作ではどうしても係止ピンが横方向に倒れようとする傾向が強くなり確実性において完全でない点と、上下移動する係止ピンを組付けるために枠側ベースプレートの厚みを大きくする必要が生じる点が改良点として挙げられる。また開放時に最も扉の荷重を受ける中間プレートに大きな円弧状の長孔を設けたため強度を得にくい構成であることも問題として残っている。   However, in the above configuration, since the locking pin's vertical movement operation is adopted as a mechanism to prevent the reverse bending phenomenon of the intermediate plate, when the door side plate is closed, the locking pin tip is pushed in the vertical direction by the horizontal rotation of the door side plate. This operation requires a sinking action, and this action inevitably increases the tendency of the locking pin to fall in the lateral direction, which is not perfect in terms of certainty, and the thickness of the frame base plate for assembling the locking pin that moves up and down The point that needs to be increased is an improvement. Another problem remains that the structure is difficult to obtain strength because a large arc-shaped long hole is provided in the intermediate plate that receives the load of the door most when opened.

本発明は上記問題点を解決するためになされたものであり、扉が閉じている状態ではヒンジ装置全体が完全に扉面と面一となるように構成し、かつ１８０°の開閉が可能であり、誤作動である逆折れ現象をより確実に防止し、強度面やコンパクト性においても優れたヒンジ装置を提供することを目的とする。
実開平２−１１９８３ 実開平５−７１３８２ 特開２００２−２５０１７１ The present invention has been made to solve the above-described problems. When the door is closed, the hinge device is configured so that the entire hinge device is completely flush with the door surface, and can be opened and closed by 180 °. The purpose of the present invention is to provide a hinge device that more reliably prevents a reverse folding phenomenon, which is a malfunction, and is excellent in strength and compactness.
2-11983 5-71382 JP 2002-250171 A

まず最初の構成としては、枠側ベースプレートと中間プレートと扉側プレートと第一回転軸と第二回転軸を設け、枠側ベースプレートと中間プレートを扉の厚み内に配置した第一回転軸にて回転自在に連結し、中間プレートと扉側プレートを第一回転軸より戸先側に配置された第二回転軸にて回転自在に連結する。そして端部に折れ曲がり部分を有した第一円弧状長孔と端部に幅広部分を有した第二円弧状長孔を枠側ベースプレート面上の第一回転軸を中心とした円軌道上に形成し、第一係止ピンと第二係止ピンを両円弧状長孔内に挿入する。   The first configuration consists of a frame-side base plate, an intermediate plate, a door-side plate, a first rotating shaft, and a second rotating shaft, with the frame-side base plate and the intermediate plate arranged within the door thickness. The intermediate plate and the door-side plate are rotatably connected by a second rotary shaft disposed closer to the door end than the first rotary shaft. Then, a first arc-shaped elongated hole having a bent portion at the end and a second arc-shaped elongated hole having a wide portion at the end are formed on a circular track centering on the first rotation axis on the frame-side base plate surface. Then, the first locking pin and the second locking pin are inserted into both arc-shaped elongated holes.

前記第一円弧状長孔と第二円弧状長は枠側ベースプレートの第一回転軸を中心とした円軌道上の異なる半径の位置に配置され、同じ所定の開き角度を有しており、折れ曲がり部分若しくは幅広部分が戸先側になるように形成しておく。さらに中間プレートに第一係止ピン挿入用長孔と第二係止ピン挿入用長孔を設け、扉側プレートにＵ字溝と係合凹部を設け、第一係止ピンを第一円弧状長孔と第一係止ピン挿入長孔を通してＵ字溝内に配置し、第二係止ピンを第二円弧状長孔と第二係止ピン挿入長孔を通して係合凹部に配置し、さらに第一円弧状長孔と折れ曲がり部分との交差部分にばね部材を装着する。   The first arc-shaped slot and the second arc-shaped slot are arranged at different radii on the circular orbit about the first rotation axis of the frame-side base plate, have the same predetermined opening angle, and are bent. A part or a wide part is formed so as to be on the door end side. Further, the intermediate plate is provided with a first locking pin insertion slot and a second locking pin insertion slot, the door side plate is provided with a U-shaped groove and an engagement recess, and the first locking pin has a first arc shape. A long hole and a first locking pin insertion long hole are disposed in the U-shaped groove, a second locking pin is disposed in the engagement recess through the second arc-shaped long hole and the second locking pin insertion long hole, and A spring member is attached to the intersection of the first arc-shaped elongated hole and the bent portion.

扉が閉じているときは枠側ベースプレートと中間プレートと扉側プレートは完全に重なった配置であり、枠側ベースプレートと中間プレートと扉側プレートの側面が扉面と面一になっており、第一係止ピンと第二係止ピンは第一円弧状長孔と第二円弧状長孔の吊元側端部に位置している。この状態から扉を開くと、扉側プレートは第一回転軸と第二回転軸のどちらかを中心に回転しようとするのであるが、第二係止ピンが係合凹部に嵌った状態であるため第二回転軸を中心としては回転できず、その結果扉側プレートは第二係止ピンを押しながら中間プレートと共に第一回転軸を中心に回転動作することになり、このとき第二係止ピンは第二円弧状長孔内を移動し、同時に第一係止ピンも第一円弧状長孔内を移動する。つまり中間プレートと扉側プレートは重なったままの状態で、両係止ピンが両円弧状長孔と折れ曲がり部分若しくは幅広部分との交差部分に当接する所定角度位置まで第一回転軸を中心に回転することになる。   When the door is closed, the frame side base plate, the intermediate plate and the door side plate are completely overlapped, and the side surfaces of the frame side base plate, the intermediate plate and the door side plate are flush with the door surface. The one locking pin and the second locking pin are located at the suspension side end portions of the first arc-shaped elongated hole and the second arc-shaped elongated hole. When the door is opened from this state, the door-side plate tries to rotate around either the first rotation shaft or the second rotation shaft, but the second locking pin is in a state of being fitted in the engagement recess. Therefore, it cannot rotate around the second rotation axis, and as a result, the door side plate rotates around the first rotation axis together with the intermediate plate while pushing the second locking pin. The pin moves in the second arc-shaped slot, and at the same time, the first locking pin also moves in the first arc-shaped slot. In other words, the intermediate plate and the door side plate remain overlapped, and both locking pins rotate around the first rotation axis to a predetermined angular position where they touch the intersections of both arc-shaped elongated holes and the bent portion or the wide portion. Will do.

次に所定角度位置にまで扉が回転すると中間プレートは停止するのであるが、この位置で中間プレートと扉側プレートがまだ完全に重なっている状態では第一係止ピンは扉側プレートのＵ字溝奥辺に当接しているために、ばね部材に逆らって第一円弧状長孔と折れ曲がり部分との交差部分に保持されており、このとき第二係止ピンは第二円弧状長孔と幅広部分との交差部分に移動してきている。   Next, when the door rotates to a predetermined angular position, the intermediate plate stops. At this position, when the intermediate plate and the door side plate are still completely overlapped, the first locking pin is the U-shape of the door side plate. Since it is in contact with the back of the groove, it is held at the intersection of the first arc-shaped elongated hole and the bent portion against the spring member. At this time, the second locking pin is the second arc-shaped elongated hole and It has moved to the intersection with the wide part.

上記の状態からさらに扉を開けると、中間プレートはこれ以上回転できないため扉側プレートは第二回転軸を中心として回転しようとする。このとき第二係止ピンは第二円弧状長孔と幅広部分との交差部分に配置されているため、係合凹部が第二係止ピンを幅広部分に押しのける動作が可能になり、扉側プレートのみが第二回転軸を中心に回転する動作が得られ、扉側プレートと共に扉を所定角度位置から大きく１８０°以上にまで回転させることができることになる。またこの扉側プレートの第二回転軸を中心とした回転動作の初期の段階で、Ｕ字溝奥辺が移動して第一係止ピンがばね部材により折れ曲がり部分に挿入する動作を得、その結果中間プレートの閉じる方向への回転を阻止することが可能になる。   When the door is further opened from the above state, the intermediate plate cannot rotate any more, so the door side plate tries to rotate around the second rotation axis. At this time, since the second locking pin is arranged at the intersection of the second arc-shaped elongated hole and the wide portion, the engaging recess can move the second locking pin to the wide portion, and the door side Only the plate rotates about the second rotation axis, and the door can be rotated together with the door side plate from the predetermined angle position to 180 ° or more. In addition, at the initial stage of the rotation operation around the second rotation axis of the door side plate, the U-shaped groove back side is moved to obtain the operation that the first locking pin is inserted into the bent portion by the spring member, As a result, the intermediate plate can be prevented from rotating in the closing direction.

今度は大きく開放した状態から扉を閉じると、所定角度位置に戻る直前に扉側プレートのＵ字溝奥辺が折れ曲がり部分端部に位置する第一係止ピンに当接し、第一円弧状長孔との交差部分にまで押し込む動作を得ることになる。その結果、中間プレートの閉じる方向への回転動作を可能にし、同時に係合凹部が第二係止ピンを第二円弧状長孔に移動させ、中間プレートと扉側プレートが完全に重なった状態で扉が閉鎖する動作を得ることができる。   Next, when the door is closed from a state where it is largely opened, the back side of the U-shaped groove of the door side plate is bent and comes into contact with the first locking pin located at the end of the bent portion immediately before returning to the predetermined angle position, and the first arc-shaped length The operation of pushing into the intersection with the hole is obtained. As a result, the intermediate plate can be rotated in the closing direction, and at the same time, the engagement recess moves the second locking pin to the second arc-shaped elongated hole so that the intermediate plate and the door side plate are completely overlapped. The operation of closing the door can be obtained.

次に別の構成を説明する。この構成も枠側ベースプレートと中間プレートと扉側プレートと第一回転軸と第二回転軸を設け、枠側ベースプレートと中間プレートを第一回転軸で、中間プレートと扉側プレートを第二回転軸で回転自在に連結するのは同様である。ここでこの別の構成では枠側ベースプレートの第一回転軸を中心とした円軌道上に幅広部分を有した第二円弧状長孔を設ける。また両端に第一係止ピンと第二係止ピンを装着したプロペラ状の連動アームを設け、第一係止ピン挿入用長孔を有した中間プレートに連動アームを連動アーム用回転軸にて第二係止ピンが枠側ベースプレート方向に、第一係止ピンが扉側プレート方向に突出する配置で回転自在に装着する。また扉側プレートの第二回転軸を中心とした円軌道上に折れ曲がり部分を有した第一円弧状長孔を設ける。つまり第二係止ピンは枠側ベースプレートの第二円弧状長孔に挿入され、第一係止ピンは中間プレートの第一係止ピン挿入用長孔を通して扉側プレートの第一円弧状長孔に挿入されることになる。   Next, another configuration will be described. This configuration also includes a frame-side base plate, an intermediate plate, a door-side plate, a first rotating shaft, and a second rotating shaft, the frame-side base plate and the intermediate plate serving as the first rotating shaft, and the intermediate plate and the door-side plate serving as the second rotating shaft. It is the same to connect in a freely rotatable manner. Here, in this other configuration, a second arc-shaped long hole having a wide portion is provided on a circular orbit centering on the first rotation axis of the frame-side base plate. Also, a propeller-like interlocking arm with a first locking pin and a second locking pin attached to both ends is provided, and the interlocking arm is connected to the intermediate plate having the first locking pin insertion slot with the rotating shaft for the interlocking arm. The two locking pins are rotatably mounted in such a manner that the first locking pins protrude in the frame side base plate direction and the first locking pins in the door side plate direction. In addition, a first arc-shaped elongated hole having a bent portion is provided on a circular track around the second rotation axis of the door side plate. That is, the second locking pin is inserted into the second arc-shaped elongated hole of the frame-side base plate, and the first locking pin passes through the first locking pin insertion elongated hole of the intermediate plate and the first arc-shaped elongated hole of the door-side plate. Will be inserted.

扉が閉じているときは最初の構成と同様に枠側ベースプレートと中間プレートと扉側プレートは重なった状態であり、第二係止ピンは第二円弧状長孔の吊元側端部に位置し、第一係止ピンは第一円弧状長孔の折れ曲がり部分端部に位置するように構成しておく。このとき扉側プレートの折れ曲がり部分と中間プレートの第一係止ピン挿入用長孔が一定の傾斜角度を有するように設定しておく。この閉鎖状態から扉を開くと、扉側プレートが第一回転軸か第二回転軸のどちらかを中心として回転しようとするのであるが、第二係止ピンが第二円弧状長孔に挿入しているため連動アームは中間プレートに対して移動することはなく、第一係止ピンが折れ曲がり部分端部に配置されているため、扉側プレートの折れ曲がり部分が連動アームの第一係止ピンを引っ張る動作になり、したがって連動アームを含む中間プレートと扉側プレートとが重なったまま第一回転軸を中心として回転することになる。   When the door is closed, the frame side base plate, the intermediate plate, and the door side plate are overlapped as in the first configuration, and the second locking pin is located at the suspension side end of the second arc-shaped elongated hole. And the 1st locking pin is comprised so that it may be located in the bending part edge part of a 1st circular arc-shaped long hole. At this time, the bent portion of the door side plate and the first locking pin insertion slot of the intermediate plate are set so as to have a certain inclination angle. When the door is opened from this closed state, the door-side plate tries to rotate around either the first rotation axis or the second rotation axis, but the second locking pin is inserted into the second arc-shaped slot. Because the interlocking arm does not move relative to the intermediate plate, the first locking pin is located at the end of the bent part, so the bent part of the door side plate is the first locking pin of the interlocking arm. Therefore, the intermediate plate including the interlocking arm and the door side plate are rotated with the first rotation axis as a center.

また所定角度位置で第二係止ピンが第二円弧状長孔と幅広部分との交差部分に当接するため中間プレートは停止する。この段階からさらに扉を開けると中間プレートはこれ以上回転できないため扉側プレートは第二回転軸を中心に回転しようとし、第一係止ピンは扉側プレートの傾斜角度を有した折れ曲がり部分に押され、折れ曲がり部分内を移動しながら同時に中間プレートの第一係止ピン挿入用長孔内をも移動することになる。この第一係止ピンの動作は連動アームの回転動作であり、第一係止ピンが折れ曲がり部分と第一円弧状長孔との交差部分に達した段階で扉側プレートの第二回転軸を中心とした回転動作が可能になり、そのまま扉を大きく開けることができることになる。また、この連動アームの回転動作により同時に第二係止ピンが幅広部分に挿入し、中間プレートの閉じる方向への回転動作を阻止することが可能になる。   Further, since the second locking pin comes into contact with the intersecting portion of the second arc-shaped elongated hole and the wide portion at a predetermined angular position, the intermediate plate stops. If the door is further opened from this stage, the intermediate plate cannot rotate any further, so the door side plate tries to rotate around the second rotation axis, and the first locking pin is pushed into the bent part with the inclination angle of the door side plate. In addition, while moving in the bent portion, it also moves in the first locking pin insertion slot in the intermediate plate. The movement of the first locking pin is the rotation of the interlocking arm. When the first locking pin reaches the intersection of the bent part and the first arc-shaped elongated hole, the second rotation shaft of the door side plate is moved. The rotation operation around the center becomes possible, and the door can be greatly opened as it is. Moreover, the second locking pin is simultaneously inserted into the wide portion by the rotating operation of the interlocking arm, and the rotating operation in the closing direction of the intermediate plate can be prevented.

また大きく開放した状態から扉を閉じると、扉側プレートが所定角度位置に戻る直前に第一円弧状長孔と折れ曲がり部分との交差部分が第一係止ピンに当接し、折れ曲がり部分の傾斜角度により第一係止ピンが押されて連動アームが回転し、中間プレートと扉側プレートが重なると同時に第二係止ピンが幅広部分から第二円弧状長孔に移動して、中間プレートの第一回転軸を中心とした閉じる方向への動作を可能とし、そのまま扉を完全に閉鎖することができることになる。   When the door is closed from a state where it is largely open, the intersection of the first arc-shaped elongated hole and the bent portion comes into contact with the first locking pin immediately before the door-side plate returns to the predetermined angle position, and the inclination angle of the bent portion The first locking pin is pushed by this, the interlocking arm rotates, the intermediate plate and the door side plate overlap, and at the same time the second locking pin moves from the wide part to the second arcuate slot, The operation in the closing direction around one rotation axis is possible, and the door can be completely closed as it is.

次に枠体に扉を吊り込む際の手段を説明する。ここで枠側ベースプレートと中間プレートと扉側プレートによる構成の上部ヒンジ装置と、同様の構成で上下を反転させた配置の下部ヒンジ装置にて１セットのヒンジ装置とする。また、この吊り込み手段は前述の最初の構成と別の構成のどちらにおいても同様に可能である。まず枠側ベースプレートと中間プレートを第一回転軸にてあらかじめ組み付けておき、枠体の吊元側上下位置に対面させた配置で装着する。また扉側プレートのみを分離して扉の上下吊元側に装着する。このとき下部ヒンジ装置の第二回転軸は中間プレートに固定しておき、上部ヒンジ装置の第二回転軸は抜き差し可能に構成しておくとよい。つまり下部ヒンジ装置の扉側プレートには第二回転軸挿入孔を設け、上部ヒンジ装置では中間プレートと扉側プレート両方に第二回転軸挿入孔を設けておき、第二回転軸を着脱できるように構成しておく。   Next, means for hanging the door on the frame will be described. Here, an upper hinge device constituted by a frame side base plate, an intermediate plate, and a door side plate, and a lower hinge device arranged in the upside down manner in the same configuration are used as one set of hinge devices. Further, the suspension means can be similarly used in either the first configuration or another configuration described above. First, the frame-side base plate and the intermediate plate are assembled in advance with the first rotating shaft, and are mounted so as to face the vertical position on the suspension base side of the frame body. Also, only the door side plate is separated and attached to the upper and lower suspension side of the door. At this time, the second rotating shaft of the lower hinge device is preferably fixed to the intermediate plate, and the second rotating shaft of the upper hinge device is configured to be detachable. In other words, the second rotation shaft insertion hole is provided in the door side plate of the lower hinge device, and the second rotation shaft insertion hole is provided in both the intermediate plate and the door side plate in the upper hinge device so that the second rotation shaft can be attached and detached. Configure it to

次に枠側ベースプレートに対して中間プレートのみを所定角度位置にまで回転させた状態にし、扉側プレートを装着した扉を所定角度位置より大きく開いた状態で両中間プレート間に挿入し、下部ヒンジ装置の中間プレートの第二回転軸に扉側プレートの第二回転軸挿入孔を嵌め込む。そして扉を起こしながら上部ヒンジ装置の中間プレートの第二回転軸挿入孔と扉側プレートの第二回転軸挿入孔の位置を合わせて第二回転軸を両者に差し込み、さらに第二回転軸を抜けないように保持して扉を確実に吊り込む。   Next, only the intermediate plate is rotated to a predetermined angular position with respect to the frame side base plate, and the door with the door side plate is inserted between both intermediate plates in a state where the door is opened larger than the predetermined angular position. The second rotary shaft insertion hole of the door side plate is fitted into the second rotary shaft of the intermediate plate of the apparatus. While raising the door, align the second rotary shaft insertion hole of the intermediate plate of the upper hinge device and the second rotary shaft insertion hole of the door side plate, insert the second rotary shaft into both, and then pull out the second rotary shaft. Hold the door securely and hang the door securely.

また他の吊り込み手段を用いてもよく、あらかじめ枠側ベースプレートと中間プレートを第一回転軸で組み付けて枠体の上下に装着し、扉側プレートのみを分離して扉の上下に装着するのは同様であり、今度は上部ヒンジ装置の中間プレートか扉側プレートのどちらか片方の第二回転軸挿入孔をＵ型形状の第二回転軸挿入溝に変えて形成し、他方に第二回転軸を装着しておき、横方向から扉と共に第二回転軸を第二回転軸挿入溝に嵌め込んで、その後蓋部材を被せて抜けないように固定する手段であっても良い。   Other suspension means may be used. The frame side base plate and the intermediate plate are assembled with the first rotating shaft in advance and mounted on the top and bottom of the frame body, and only the door side plate is separated and mounted on the top and bottom of the door. Is the same, this time the second rotation shaft insertion hole of either the intermediate plate or door side plate of the upper hinge device is changed to a U-shaped second rotation shaft insertion groove, and the other is the second rotation A means may be provided in which a shaft is mounted, the second rotating shaft is fitted into the second rotating shaft insertion groove together with the door from the lateral direction, and then the cover member is covered and fixed so as not to come off.

上記のように構成することにより、扉の１８０°の開放が可能であり、かつヒンジ装置全体が扉の厚み内に配置され扉を閉じたときにはヒンジ装置の側面は扉面と面一になるためデザイン性に優れており、軸芯部分が扉面から突出しないため安全性を高めることができ、取り付けのための枠体や扉の掘り込みも簡単なヒンジ装置を提供することが可能となる。   By configuring as described above, the door can be opened 180 °, and when the entire hinge device is disposed within the thickness of the door and the door is closed, the side surface of the hinge device is flush with the door surface. It is possible to provide a hinge device that is excellent in design, can improve safety because the shaft core portion does not protrude from the door surface, and can easily dig in the frame for mounting and the door.

扉側プレートの所定角度位置付近での第二回転軸を中心とする回転動作により、第一係止ピンと第二係止ピンを水平方向に移動させて中間プレートの回転動作を規制または解除する構成であるため、扉を開ける動作だけでなく閉じる動作においても中間プレートの逆折れ現象を確実に阻止することができ、より円滑な開閉操作を得ることが可能になる。また両係止ピンの動作が水平方向であるためヒンジ装置全体の厚みをより薄く設定することができ、特に別の構成では中間プレートの動作を規制及び解除するためのばね部材さえ必要無い構成にすることができる。   A configuration in which the first locking pin and the second locking pin are moved in the horizontal direction by the rotation operation around the second rotation axis in the vicinity of the predetermined angular position of the door side plate to restrict or release the rotation operation of the intermediate plate. Therefore, the reverse folding phenomenon of the intermediate plate can be reliably prevented not only in the operation of opening the door but also in the closing operation, and a smoother opening / closing operation can be obtained. In addition, since the operation of both locking pins is horizontal, the thickness of the entire hinge device can be set thinner, and in another configuration, even a spring member for regulating and releasing the operation of the intermediate plate is not necessary. can do.

扉の重量を支えるにおいて最も強度を必要とする中間プレートに大きな孔や長孔等を極力設けない構成にしたため、比較的耐荷重に優れた構成が実現でき、重量扉等にも十分使用可能にすることができる。   The structure that does not have large holes or long holes as much as possible in the intermediate plate that needs the most strength to support the weight of the door, so that it can realize a structure with relatively high load resistance and can be used well for heavy doors etc. can do.

ヒンジ装置を枠側ベースプレートと中間プレートを第一回転軸にて連結した構成と扉側プレートに分割し、あらかじめ枠体に枠側ベースプレートと中間プレートを、扉に扉側プレートを装着しておくことにより、扉側プレートを取り付けた扉を両中間プレート間に挿入し、第二回転軸にて中間プレートと扉側プレートを連結するだけの容易な吊り込み作業が実施可能になる。   The hinge device is divided into a structure in which the frame side base plate and the intermediate plate are connected by the first rotating shaft and the door side plate, and the frame side base plate and the intermediate plate are mounted on the frame body in advance and the door side plate is mounted on the door. Thus, it is possible to perform an easy suspending operation in which the door with the door-side plate attached is inserted between the intermediate plates and the intermediate plate and the door-side plate are connected by the second rotating shaft.

FIG. 2 is a front view of the hinge device of the present invention in a closed state in which the hinge device is attached to the door 25 and the frame body 26. The upper hinge device a and the lower hinge device b constitute a set of hinge devices, and the arrangement is vertically The state is reversed. Here, FIG. 1 shows the lower hinge device b in a state in which the door 25 is closed. The upper hinge device a and the lower hinge device b have slightly different parts depending on the suspension means, but the basic configuration is shown.

Therefore, the intermediate plate 2 rotates about the first rotation shaft 4 with respect to the frame side base plate 1, and the door side plate 3 rotates about the second rotation shaft 5 with respect to the intermediate plate 2. Here, as shown in FIG. 1, the frame-side base plate 1 is mounted at a position where the side surface is flush with the door 25, and the door-side plate 3 is also mounted so that the side surface is flush with the door 25. Similarly, the hinge device is formed by connecting both sides of the door 25 so that the side faces are flush with the door 25.

In addition, the bottom portion around the first arc-shaped elongated hole 6 and the second arc-shaped elongated hole 7 is stealed, and a spring member 12 is mounted at the intersection of the first arc-shaped elongated hole 6 and the bent portion 8. Keep it.

中間プレート２も図４に示すように板状であり、第一回転軸挿入孔１３と第二回転軸５を有し、さらに第一係止ピン挿入用長孔１５と第二係止ピン挿入用長孔１６を設けておく。この第一係止ピン挿入用長孔１５と第二係止ピン挿入用長孔１６は、図６に示す枠側ベースプレート１と中間プレート２が完全に重なった状態での第一円弧状長孔６と第二円弧状長孔７の吊元側端部に面対する位置に配置し、その形状は中間プレート２が第一回転軸４を中心に第一円弧状長孔６と第二円弧状長孔７の所定開き角度だけ回転した段階で、第一係止ピン挿入用長孔１５は折れ曲がり部分８と、第二係止ピン挿入用長孔１６は幅広部分９とそれぞれが完全に重なり合うように形成しておく。   The intermediate plate 2 is also plate-shaped as shown in FIG. 4, has a first rotating shaft insertion hole 13 and a second rotating shaft 5, and further has a first locking pin insertion slot 15 and a second locking pin inserted. An oblong hole 16 is provided. The first locking pin insertion slot 15 and the second locking pin insertion slot 16 are the first arcuate slot when the frame side base plate 1 and the intermediate plate 2 shown in FIG. 6 and the second arc-shaped elongated hole 7 are arranged at positions facing the suspension side end, and the shape of the intermediate plate 2 is the first arc-shaped elongated hole 6 and the second arc-shaped centered on the first rotating shaft 4. When the long hole 7 is rotated by a predetermined opening angle, the first locking pin insertion long hole 15 and the second locking pin insertion long hole 16 are completely overlapped with the wide part 9, respectively. To form.

扉側プレート３も図５に示すように同様に板状であり、第二回転軸挿入孔１４を有し、その吊元側手前位置にＵ字溝１７を設け、さらにその奥位置吊元側に係合凹部１９とそれに連続した円弧辺２０を設けておく。Ｕ字溝１７は第二回転軸挿入孔１４を中心とした円弧形状であり、その奥側端部をＵ字溝奥辺１８とし、図６に示す枠側ベースプレート１と中間プレート２と扉側プレート３を重ね合わせた状態で第一円弧状長孔６の吊元側端部の奥側とＵ字溝奥辺１８が同位置になるように配置しておく。また係合凹部１９は同様に各ヒンジを重ね合わせた状態で第二円弧状長孔７の吊元側端部の手前側と同位置になるように配置し、円弧辺２０は第二回転軸５を中心とした円軌道上で、その半径は係合凹部１９の最もへこんだ位置と第二回転軸５の中心を結んだ距離よりも僅かにのみ大きくなるように設定しておく。   As shown in FIG. 5, the door-side plate 3 is also plate-shaped, has a second rotary shaft insertion hole 14, is provided with a U-shaped groove 17 at the front side of the suspension base, and is further on the back position suspension base side. An engaging recess 19 and a circular arc side 20 continuous therewith are provided. The U-shaped groove 17 has an arc shape centered on the second rotary shaft insertion hole 14, and its rear side end portion is a U-shaped groove rear side 18, and the frame side base plate 1, the intermediate plate 2, and the door side shown in FIG. 6. In a state where the plates 3 are superposed, the rear side of the suspension base side end portion of the first arc-shaped elongated hole 6 and the U-shaped groove rear side 18 are arranged at the same position. Similarly, the engaging concave portion 19 is arranged so as to be in the same position as the front side of the suspension-side end portion of the second arc-shaped elongated hole 7 in a state where the hinges are overlapped, and the arc side 20 is the second rotating shaft. On the circular orbit centered at 5, the radius is set to be slightly larger than the distance connecting the most recessed position of the engaging recess 19 and the center of the second rotating shaft 5.

次に図６に示すように第一係止ピン１０を第一円弧状長孔６の吊元側端部に、第二係止ピン１１を第二円弧状長孔７の吊元側端部に配置する。図７は図６のＡ−Ａ’断面を示しており、つば部分を有した第一係止ピン１０を第一円弧状長孔６と第一係止ピン挿入用長孔１５を通して上部先端がＵ字溝奥辺１８に接した状態で挿入する。このときつば部分とＥリング等の抜け止め部材にて中間プレート２の厚み部分を挟み込むように装着し、起立した状態を保持しながら第一円弧状長孔６に沿って水平方向にのみ移動可能にしておく。また第一係止ピン１０の上部先端は扉側プレート３上面程度までに設定し、下部先端は枠側ベースプレート１の底面から僅かに浮く程度にて設定し、第一係止ピン１０が第一円弧状長孔６と折れ曲がり部分８との交差位置に移動するとばね部材１２により折れ曲がり部分８の奥位置に付勢されるように構成しておく。   Next, as shown in FIG. 6, the first locking pin 10 is at the suspension-side end of the first arc-shaped long hole 6, and the second locking pin 11 is at the suspension-side end of the second arc-shaped long hole 7. To place. FIG. 7 shows a cross section taken along the line AA ′ of FIG. 6. The upper end of the first locking pin 10 having the collar portion is passed through the first arc-shaped elongated hole 6 and the first locking pin insertion elongated hole 15. Insert in contact with the U-shaped groove back side 18. At this time, it is mounted so that the thickness portion of the intermediate plate 2 is sandwiched between the collar portion and the retaining member such as an E-ring, and can move only along the first arc-shaped elongated hole 6 while maintaining the standing state. Keep it. The top end of the first locking pin 10 is set up to about the top surface of the door-side plate 3, and the bottom end is set so that it slightly floats from the bottom surface of the frame-side base plate 1. When the arc-shaped long hole 6 and the bent portion 8 are moved to the intersecting position, the spring member 12 biases the bent portion 8 to the inner position.

同様につば部分を有した第二係止ピン１１を第二円弧状長孔７と第二係止ピン挿入用長孔１６を通して上部先端が扉側プレート３の上面にまで届くように挿入し、このとき第二係止ピン１１先端が係合凹部１９に位置するように設定しておく。第二係止ピン１１はつば部分とワッシャ２１にて枠側ベースプレート１底面と中間プレート２上面を挟み込むように装着し、同様に上下方向に起立した状態を保持しつつ第二円弧状長孔７に沿って水平方向にのみ移動できるようにしておく。またこのつば部分とワッシャ２１で枠側ベースプレート１と中間プレート２が一定の間隔を保持し、かつ中間プレート２が上方向に抜けないようにかしめる等の手段を講じ、扉２５を開放したときの荷重をこの第二係止ピン１１で受けるようにしておく。さらに第一係止ピン１０や第二係止ピン１１の各プレート間位置に耐磨耗性の良い樹脂リング等を適宜嵌めておくとよい。   Similarly, the second locking pin 11 having a collar portion is inserted through the second arc-shaped long hole 7 and the second locking pin insertion long hole 16 so that the upper end reaches the upper surface of the door side plate 3. At this time, it is set so that the tip of the second locking pin 11 is positioned in the engaging recess 19. The second locking pin 11 is mounted so that the bottom surface of the frame side base plate 1 and the upper surface of the intermediate plate 2 are sandwiched between the collar portion and the washer 21, and the second arc-shaped elongated hole 7 is similarly held while standing up and down. It is possible to move only along the horizontal direction. Further, when the door 25 is opened by taking measures such as holding the frame side base plate 1 and the intermediate plate 2 at a certain distance with the collar portion and the washer 21 so that the intermediate plate 2 does not come out upward. Is received by the second locking pin 11. Further, a resin ring having good wear resistance or the like may be appropriately fitted between the first locking pin 10 and the second locking pin 11 between the plates.

また図１では枠側ベースプレート１の第一回転軸４と中間プレート２の第一回転軸挿入孔１３は抜き差しできるように表示しているが、図７に示すように第一回転軸４もつば部分を有する形状にして、つば部分とワッシャ２１にて枠側ベースプレート１と中間プレート２を回転可能な状態にて挟み込んでかしめてもよい。   In FIG. 1, the first rotation shaft 4 of the frame side base plate 1 and the first rotation shaft insertion hole 13 of the intermediate plate 2 are shown so that they can be inserted and removed. However, as shown in FIG. The frame side base plate 1 and the intermediate plate 2 may be sandwiched and crimped between the collar portion and the washer 21 in a shape having a portion.

次に図８にて本発明の第一実施形態でのヒンジ装置の開閉動作を説明する。図８(ａ)は扉２５が完全に閉じた状態を示しており、枠側ベースプレート１と中間プレート２と扉側プレート３は完全に重なって各プレートの側面が扉２５と面一になっている。また第一係止ピン１０と第二係止ピン１１は第一円弧状長孔６と第二円弧状長孔７の吊元側端部に位置している。この状態から扉２５を開くと、扉２５に固定されている扉側プレート３が第一回転軸４か第二回転軸５のどちらかを中心に回転することになる。ところが図８(ａ)に示すように第二係止ピン１１は扉側プレート３の円弧辺２０よりもさらにへこんだ係合凹部１９に位置しており、かつ枠側ベースプレート１の第二円弧状長孔７内に挿入しているため、扉側プレート３は第二回転軸５を中心には回転できないことになる。   Next, the opening / closing operation | movement of the hinge apparatus in 1st embodiment of this invention is demonstrated in FIG. FIG. 8A shows a state in which the door 25 is completely closed. The frame side base plate 1, the intermediate plate 2, and the door side plate 3 are completely overlapped, and the side surfaces of the respective plates are flush with the door 25. Yes. Further, the first locking pin 10 and the second locking pin 11 are located at the suspension side end portions of the first arc-shaped elongated hole 6 and the second arc-shaped elongated hole 7. When the door 25 is opened from this state, the door side plate 3 fixed to the door 25 rotates around either the first rotating shaft 4 or the second rotating shaft 5. However, as shown in FIG. 8A, the second locking pin 11 is located in the engaging recess 19 that is further recessed than the arc side 20 of the door side plate 3, and the second arc shape of the frame side base plate 1. Since it is inserted into the long hole 7, the door side plate 3 cannot rotate around the second rotation shaft 5.

したがって図８(ａ)からの開放動作は扉側プレート３が第二係止ピン１１を押しながら第一回転軸４を中心として回転する動作になり、第二係止ピン１１は第二円弧状長孔７内を移動することになる。このとき第二係止ピン１１は中間プレート２の第二係止ピン挿入用長孔１６を貫通しているため、同時に中間プレート２も第一回転軸４を中心に回転する。   Therefore, the opening operation from FIG. 8A is an operation in which the door-side plate 3 rotates around the first rotation shaft 4 while pushing the second locking pin 11, and the second locking pin 11 has a second arc shape. It moves in the long hole 7. At this time, since the second locking pin 11 passes through the second locking pin insertion slot 16 of the intermediate plate 2, the intermediate plate 2 also rotates around the first rotation shaft 4 at the same time.

また第一係止ピン１０は図８(ａ)の状態では第一円弧状長孔６の端部位置と中間プレート２の第一係止ピン挿入用長孔１５を貫通して扉側プレート３のＵ字溝奥辺１８に接しており、上記の動作により同様に中間プレート２に押されて第一円弧状長孔６に沿って移動する。そして図８(ｂ)に示す第一係止ピン１０と第二係止ピン１１が第一円弧状長孔６と折れ曲がり部分８との交差部分と、第二円弧状長孔７と幅広部分９との交差部分に当接する位置で中間プレート２は停止する。この図８(ｂ)に示す位置まで中間プレート２と扉側プレート３が回転し、中間プレート２と扉側プレート３がまだ完全に重なった状態を扉２５の所定角度位置とする。   Further, in the state of FIG. 8A, the first locking pin 10 passes through the end position of the first arc-shaped long hole 6 and the first locking pin insertion long hole 15 of the intermediate plate 2, and the door side plate 3. The U-shaped groove rear side 18 is in contact with the U-shaped groove and is moved along the first arc-shaped long hole 6 by being similarly pushed by the intermediate plate 2 by the above operation. Then, the first locking pin 10 and the second locking pin 11 shown in FIG. 8B are crossed between the first arc-shaped elongated hole 6 and the bent portion 8, the second arc-shaped elongated hole 7 and the wide portion 9. The intermediate plate 2 stops at a position where it abuts the crossing portion. The state where the intermediate plate 2 and the door side plate 3 are rotated to the position shown in FIG. 8B and the intermediate plate 2 and the door side plate 3 are still completely overlapped is defined as a predetermined angular position of the door 25.

この図８(ｂ)の段階では、折れ曲がり部分８と第一係止ピン挿入用長孔１５は完全に重なった配置になっているのであるが、第一係止ピン１０は扉側プレート３のＵ字溝奥辺１８に接しており、折れ曲がり部分８側には移動できないため、ばね部材１２を圧縮させた状態を保持している。また、第二係止ピン１１は図８(ｂ)の状態では既に第二円弧状長孔７と幅広部分９との交差部分に移動しており、第二係止ピン挿入用長孔１６は幅広部分９と同形状であるため、第二係止ピン１１は幅広部分９に移動することが可能な状態になっている。   In the stage of FIG. 8B, the bent portion 8 and the first locking pin insertion long hole 15 are arranged so as to completely overlap, but the first locking pin 10 is formed on the door side plate 3. Since it is in contact with the U-shaped groove back side 18 and cannot move to the bent portion 8 side, the spring member 12 is kept compressed. Further, in the state of FIG. 8B, the second locking pin 11 has already moved to the intersection of the second arc-shaped long hole 7 and the wide portion 9, and the second locking pin insertion long hole 16 has Since it has the same shape as the wide portion 9, the second locking pin 11 can move to the wide portion 9.

この図８(ｂ)の状態からさらに扉２５を開く方向に回転させると中間プレート２はこれ以上回転できないため、今度は第二回転軸５を中心に回転しようとする動作になる。ここで扉側プレート３の係合凹部１９と円弧辺２０との段差を第二係止ピン１１の半径より遥かに小さく設定しておくと、図８(ｃ)のように円弧辺２０が第二係止ピン１１を幅広部分９に押し込む動作と共に、扉側プレート３の第二回転軸５を中心とした回転が可能になる。したがって円弧辺２０は第二係止ピン１１が幅広部分９の端部に移動した状態で、当接しない程度の位置に設定しておくと良い。また所定角度位置からの扉２５及び扉側プレート３の第二回転軸５を中心とした回転動作の初期の段階で、扉側プレート３のＵ字溝奥辺１８も回転移動するため、図８(ｃ)のように第一係止ピン１０がばね部材１２により付勢されて折れ曲がり部分８に挿入し、その結果中間プレート２の閉じる方向への回転動作を阻止することが可能になる。つまりこの動作が中間プレート２の逆折れ現象を防止する機構である。そして図８(ｄ)のように扉側プレート３と共に扉２５を所定角度位置から大きく１８０°以上にまで回転させることができることになる。   If the door 25 is further rotated in the direction in which the door 25 is opened from the state shown in FIG. 8B, the intermediate plate 2 cannot be rotated any further. Here, if the step between the engaging recess 19 and the arc side 20 of the door side plate 3 is set to be much smaller than the radius of the second locking pin 11, the arc side 20 becomes the first as shown in FIG. Along with the operation of pushing the two locking pins 11 into the wide portion 9, the door side plate 3 can be rotated around the second rotation shaft 5. Therefore, it is preferable to set the arc side 20 at a position where it does not come into contact with the second locking pin 11 moved to the end of the wide portion 9. Further, at the initial stage of the rotation operation around the door 25 and the second rotation shaft 5 of the door side plate 3 from the predetermined angle position, the U-shaped groove rear side 18 of the door side plate 3 also rotates and moves, so that FIG. As shown in (c), the first locking pin 10 is urged by the spring member 12 and inserted into the bent portion 8, and as a result, the intermediate plate 2 can be prevented from rotating in the closing direction. That is, this operation is a mechanism for preventing the reverse bending phenomenon of the intermediate plate 2. As shown in FIG. 8D, the door 25 together with the door-side plate 3 can be rotated from the predetermined angle position to 180 ° or more.

また図８(ｄ)の状態では扉２５の荷重は下方にかかり、したがって第一回転軸４を支点として中間プレート２の第二係止ピン１１を持ち上げるようとする方向になる。そのため図７に示すように第二係止ピン１１の上部につば部分を設け、枠側ベースプレート１底面位置でワッシャ２１でかしめておくと扉２５の荷重を第二係止ピン１１にて受け止めることが可能になり、扉２５の戸先位置の垂れ下り等をも防止することができる。   Further, in the state of FIG. 8D, the load on the door 25 is applied downward, so that the second locking pin 11 of the intermediate plate 2 is lifted with the first rotating shaft 4 as a fulcrum. Therefore, as shown in FIG. 7, if a collar portion is provided on the upper portion of the second locking pin 11 and caulked with a washer 21 at the bottom surface position of the frame side base plate 1, the load of the door 25 is received by the second locking pin 11. It becomes possible to prevent the door tip position of the door 25 from hanging down.

また図８(ｄ)の大きく開いた状態から扉２５を閉じると、扉２５は第二回転軸５を中心に回転し、図８(ｃ)の所定角度位置に戻る直前で扉側プレート３のＵ字溝奥辺１８が折れ曲がり部分８端部に位置する第一係止ピン１０に当接する。さらに扉２５を閉じると図８(ｂ)の所定角度位置までに第一係止ピン１０を第一円弧状長孔６と折れ曲がり部分８との交差部分にまで押し込む動作を得る。その結果図８(ｂ)のように中間プレート２と扉側プレート３が完全に重なると同時に中間プレート２の閉じる方向への回転動作が可能になる。また上記の動作と同時に扉側プレート３の係合凹部１９が第二係止ピン１１を押して第二円弧状長孔７に移動させ、中間プレート２の第一係止ピン挿入用長孔１５と第二係止ピン挿入用長孔１６に押されて第一係止ピン１０と第二係止ピン１１が第一円弧状長孔６と第二円弧状長孔７に沿って移動し、図８(ａ)の閉鎖状態に戻る。したがって第二円弧状長孔７と幅広部分９との連続部分の段差も第二係止ピン１１の半径より遥かに小さく設定しておくとよい。   When the door 25 is closed from the state shown in FIG. 8D, the door 25 rotates about the second rotation shaft 5 and immediately before returning to the predetermined angular position shown in FIG. The U-shaped groove back side 18 is bent and comes into contact with the first locking pin 10 located at the end of the bent portion 8. When the door 25 is further closed, the first locking pin 10 is pushed to the intersection of the first arc-shaped elongated hole 6 and the bent portion 8 by the predetermined angular position shown in FIG. As a result, as shown in FIG. 8B, the intermediate plate 2 and the door side plate 3 are completely overlapped, and at the same time, the intermediate plate 2 can be rotated in the closing direction. Simultaneously with the above operation, the engaging recess 19 of the door side plate 3 pushes the second locking pin 11 to move to the second arcuate elongated hole 7, and the first locking pin insertion elongated hole 15 of the intermediate plate 2 and The first locking pin 10 and the second locking pin 11 are moved along the first arc-shaped long hole 6 and the second arc-shaped long hole 7 by being pushed by the second locking pin insertion long hole 16. It returns to the closed state of 8 (a). Therefore, the step of the continuous portion between the second arc-shaped elongated hole 7 and the wide portion 9 is preferably set to be much smaller than the radius of the second locking pin 11.

次に本発明のヒンジ装置の第二実施形態を図９〜図１４に基づいて説明する。図９は第二実施形態の下部ヒンジ装置ｂの分解斜視図であり、第二実施形態においても枠側ベースプレート１と中間プレート２と扉側プレート３と第一回転軸４と第二回転軸５を設け、枠側ベースプレート１と中間プレート２を第一回転軸４で、中間プレート２と扉側プレート３を第二回転軸５で回転自在に連結するのは同様である。図１０は枠側ベースプレート１の平面図であり、第一回転軸４を中心とした円軌道上に端部に幅広部分９を有した第二円弧状長孔７を設ける。また図１１に示すような両端に第一係止ピン１０と第二係止ピン１１を装着するプロペラ状の連動アーム２２を設け、さらに図１２に示すように第一係止ピン挿入用長孔１５を有した中間プレート２に連動アーム２２を連動アーム用回転軸２３にて第二係止ピン１１が下向き、つまり枠側ベースプレート１側に、第一係止ピン１０が上向き、つまり扉側プレート３側に突出する配置で回転自在に装着する。また図１３は扉側プレート３の平面図であり、第二回転軸挿入孔１４を中心とした円軌道上に端部に折れ曲がり部分８を有した第一円弧状長孔６を設ける。   Next, 2nd embodiment of the hinge apparatus of this invention is described based on FIGS. FIG. 9 is an exploded perspective view of the lower hinge device b of the second embodiment. In the second embodiment as well, the frame-side base plate 1, the intermediate plate 2, the door-side plate 3, the first rotating shaft 4, and the second rotating shaft 5 are used. It is the same that the frame side base plate 1 and the intermediate plate 2 are rotatably connected by the first rotating shaft 4, and the intermediate plate 2 and the door side plate 3 are rotatably connected by the second rotating shaft 5. FIG. 10 is a plan view of the frame-side base plate 1, and a second arc-shaped long hole 7 having a wide portion 9 at the end is provided on a circular orbit centered on the first rotation shaft 4. Further, a propeller-like interlocking arm 22 for mounting the first locking pin 10 and the second locking pin 11 is provided at both ends as shown in FIG. 11, and further, a long hole for inserting the first locking pin as shown in FIG. The intermediate locking plate 22 has the interlocking arm 22 and the interlocking arm rotating shaft 23, the second locking pin 11 faces downward, that is, the frame side base plate 1 side, and the first locking pin 10 faces upward, that is, the door side plate. It is mounted so as to be rotatable in an arrangement that projects to the 3 side. FIG. 13 is a plan view of the door-side plate 3, and a first arc-shaped elongated hole 6 having a bent portion 8 at the end is provided on a circular track centering on the second rotation shaft insertion hole 14.

ここで開閉動作においては、上記のように各ヒンジを重ね合わせた状態で第二係止ピン１１は枠側ベースプレート１の第二円弧状長孔７に挿入され、第一係止ピン１０は中間プレート２の第一係止ピン挿入用長孔１５を通して扉側プレート３の第一円弧状長孔６に挿入されることが重要である。しかし第一実施形態と同様に、開放時の扉２５の荷重を受ける役割を第二係止ピン１１にて備える必要があり、そこで図９に示すように第二係止ピン１１の下部につば部分を設け、上部を連動アーム２２と中間プレート２に貫通させ、連動アーム２２と共に移動可能な状態を維持しつつ中間プレート２上面にてワッシャ２１等でかしめて固定するとよい。   Here, in the opening and closing operation, the second locking pin 11 is inserted into the second arc-shaped elongated hole 7 of the frame-side base plate 1 with the hinges overlapped as described above, and the first locking pin 10 is the middle. It is important that the first locking pin insertion slot 15 of the plate 2 is inserted into the first arc-shaped slot 6 of the door side plate 3. However, as in the first embodiment, it is necessary to provide the second locking pin 11 with a role of receiving the load of the door 25 at the time of opening, and there is a collar below the second locking pin 11 as shown in FIG. A portion may be provided, and the upper part may be passed through the interlocking arm 22 and the intermediate plate 2, and may be fixed by caulking with a washer 21 or the like on the upper surface of the intermediate plate 2 while maintaining a movable state together with the interlocking arm 22.

次に第二実施形態でのヒンジ装置の開閉動作を図１４に基づいて説明する。第二実施形態も扉２５が閉じているときは図１４(ａ)に示すように各プレートは完全に重なった状態であり外観は図２とほとんど同じである。ここで第二実施形態の特徴としては第一係止ピン１０と第二係止ピン１１を連動アーム２２にて連結した点とばね部材１２を排除した点が重要とされる。図１４(ａ)の状態では第二係止ピン１１が第二円弧状長孔７の吊元側端部に位置し、第一係止ピン１０が第一係止ピン挿入用長孔１５を貫通して第一円弧状長孔６の折れ曲がり部分８端部に位置するように構成しておく。また折れ曲がり部分８と中間プレート２の第一係止ピン挿入用長孔１５が一定の傾斜角度を有するように設定しておく。   Next, the opening / closing operation | movement of the hinge apparatus in 2nd embodiment is demonstrated based on FIG. In the second embodiment, when the door 25 is closed, the plates are completely overlapped as shown in FIG. 14A, and the appearance is almost the same as FIG. Here, as a feature of the second embodiment, the point that the first locking pin 10 and the second locking pin 11 are connected by the interlocking arm 22 and the point that the spring member 12 is excluded are important. In the state of FIG. 14A, the second locking pin 11 is positioned at the end of the second arcuate elongated hole 7 and the first locking pin 10 has the first locking pin insertion slot 15. It penetrates and is constituted so that it may be located in the bent part 8 end of the 1st circular arc-like long hole 6. The bent portion 8 and the first locking pin insertion slot 15 of the intermediate plate 2 are set so as to have a constant inclination angle.

上記の状態から扉２５を開けると、第一回転軸４か第二回転軸５のどちらかを中心に回転しようとするのであるが、第二係止ピン１１が第二円弧状長孔７の端部に位置しているため、連動アーム２２は中間プレート２に対しては回転移動できず、したがって第一係止ピン１０も折れ曲がり部分８端部から移動できないため、扉側プレート３は第二回転軸５に対しては回転できないことになり、その結果扉側プレート３の折れ曲がり部分８が連動アーム２２の第一係止ピン１０を引っ張る動作になる。また第一係止ピン１０は中間プレート２の第一係止ピン挿入用長孔１５を貫通しているため、連動アーム２２を含む中間プレート２と扉側プレート３とが重なったまま図１４(ｂ)に示すように第一回転軸４を中心として回転する動作になり、図１４(ｃ)の所定角度位置で第二係止ピン１１が第二円弧状長孔７と幅広部分９との交差部分に当接して中間プレート２は停止する。   When the door 25 is opened from the above state, it tries to rotate around either the first rotating shaft 4 or the second rotating shaft 5. Since the interlocking arm 22 cannot be rotated with respect to the intermediate plate 2 because it is located at the end portion, and therefore the first locking pin 10 cannot be moved from the end of the bent portion 8, the door side plate 3 can be As a result, the bent portion 8 of the door side plate 3 pulls the first locking pin 10 of the interlocking arm 22. Further, since the first locking pin 10 passes through the first locking pin insertion slot 15 of the intermediate plate 2, the intermediate plate 2 including the interlocking arm 22 and the door side plate 3 are overlapped with each other as shown in FIG. As shown in FIG. 14B, the second rotating pin 11 is rotated between the second arcuate long hole 7 and the wide portion 9 at a predetermined angular position in FIG. The intermediate plate 2 stops at the intersection.

この図１４(ｃ)の状態からさらに扉２５を開けると中間プレート２はこれ以上回転できないため、扉側プレート３は第二回転軸５を中心に回転しようとする。ここで図１４(ｃ)に示す所定角度位置では中間プレート２と共に連動アーム２２も移動してきており、第二係止ピン１１は既に第二円弧状長孔７と幅広部分９の交差部分に位置している。したがって連動アーム２２は第二係止ピン１１が幅広部分９内で移動する範囲内で回転可能な状態になっていることになる。このとき第一係止ピン挿入用長孔１５と折れ曲がり部分８が重なり合って互いに傾斜角度を有しているため、扉側プレート３が第二回転軸５を中心としてさらに回転しようとすると、折れ曲がり部分８が第一係止ピン１０を押し、図１４(ｄ)に示すように連動アーム２２が回転して第一係止ピン１０は図１４(ｅ)に示す折れ曲がり部分８と第一円弧状長孔６との交差部分にまで移動することになる。   If the door 25 is further opened from the state shown in FIG. 14C, the intermediate plate 2 cannot rotate any further, so the door side plate 3 tries to rotate around the second rotation shaft 5. Here, the interlocking arm 22 has moved together with the intermediate plate 2 at the predetermined angular position shown in FIG. 14 (c), and the second locking pin 11 has already been positioned at the intersection of the second arcuate elongated hole 7 and the wide portion 9. doing. Therefore, the interlocking arm 22 is in a state of being rotatable within the range in which the second locking pin 11 moves within the wide portion 9. At this time, since the first locking pin insertion slot 15 and the bent portion 8 overlap each other and have an inclination angle, when the door side plate 3 tries to further rotate around the second rotation shaft 5, the bent portion 8 pushes the first locking pin 10, and the interlocking arm 22 rotates as shown in FIG. 14 (d), so that the first locking pin 10 and the bent portion 8 shown in FIG. It moves to the intersection with the hole 6.

すると、引き続き第一係止ピン１０に沿って第一円弧状長孔６が移動する扉側プレート３の第二回転軸５を中心とした回転動作が可能になり、図１４(ｆ)に示すようにそのまま扉２５を大きく開けることができることになる。また図１４(ｅ)に示すように、この連動アーム２２の回転動作と同時に第二係止ピン１１が幅広部分９に挿入するように設定しておくと、中間プレート２の閉じる方向への回転動作を阻止することが可能になり、中間プレート２の逆折れを防止することができる。   Then, the rotation operation around the second rotation shaft 5 of the door side plate 3 in which the first arc-shaped elongated hole 6 continues to move along the first locking pin 10 becomes possible, as shown in FIG. Thus, the door 25 can be greatly opened as it is. Further, as shown in FIG. 14 (e), if the second locking pin 11 is set to be inserted into the wide portion 9 simultaneously with the rotation of the interlocking arm 22, the rotation of the intermediate plate 2 in the closing direction is performed. The operation can be prevented, and the reverse folding of the intermediate plate 2 can be prevented.

上記の全体の動作をまとめると、図１４(ａ)〜図１４(ｃ)までは中間プレート２に対して連動アーム２２は移動せず、第二係止ピン１１が第二円弧状長孔７に案内されて第一回転軸４を中心に中間プレート２と扉側プレート３が重なったままで回転し、図１４(ｃ)〜図１４(ｅ)の間で連動アーム２２が回転して第二係止ピン１１が幅広部分９に、第一係止ピン１０が第一円弧状長孔６に移動して案内動作の切り替えを実施し、図１４(ｅ)〜図１４(ｆ)ではやはり中間プレート２に対して連動アーム２２は移動せず、第一係止ピン１０が第一円弧状長孔６に案内されて第二回転軸５を中心に扉２５側プレート３のみがさらに回転する動作になる。また上記説明においては部分的に分割して実施したが、これらの動作は途中で一旦停止するようなことはなく、一連の円滑な開放動作として実施することができる。   Summarizing the above overall operation, the interlocking arm 22 does not move with respect to the intermediate plate 2 from FIGS. 14A to 14C, and the second locking pin 11 has the second arc-shaped elongated hole 7. And the intermediate plate 2 and the door side plate 3 are rotated with the first rotating shaft 4 as a center, and the interlocking arm 22 rotates between FIGS. The locking pin 11 is moved to the wide portion 9 and the first locking pin 10 is moved to the first arcuate elongated hole 6 to switch the guide operation. In FIGS. The interlocking arm 22 does not move relative to the plate 2, and the first locking pin 10 is guided by the first arc-shaped elongated hole 6 and only the door 25 side plate 3 rotates further about the second rotation shaft 5. become. In the above description, the operation is partially divided, but these operations are not temporarily stopped in the middle, and can be performed as a series of smooth opening operations.

次に図１４(ｆ)に示す大きく開放した状態から扉２５を閉じると、扉側プレート３が所定角度位置に戻る直前の図１４(ｅ)の段階で第一円弧状長孔６と折れ曲がり部分８との交差部分が第一係止ピン１０に当接し、折れ曲がり部分８の傾斜角度により第一係止ピン１０が押されて連動アーム２２が回転し、扉側プレート３が図１４(ｃ)の所定角度位置にまで戻ると第二係止ピン１１が幅広部分９から第二円弧状長孔７に移動して中間プレート２の第一回転軸４を中心とした閉じる方向への回転動作を可能とし、中間プレート２と扉側プレート３が重なると同時にそのままの状態で扉２５を完全に閉鎖することができることになる。   Next, when the door 25 is closed from the largely opened state shown in FIG. 14 (f), the first arc-shaped elongated hole 6 and the bent portion are in the stage of FIG. 14 (e) just before the door side plate 3 returns to the predetermined angular position. 8 is brought into contact with the first locking pin 10, the first locking pin 10 is pushed by the inclination angle of the bent portion 8, the interlocking arm 22 is rotated, and the door side plate 3 is moved as shown in FIG. The second locking pin 11 moves from the wide portion 9 to the second arc-shaped elongated hole 7 and returns to the closing direction around the first rotating shaft 4 of the intermediate plate 2 when it returns to the predetermined angular position. The door 25 can be completely closed at the same time as the intermediate plate 2 and the door side plate 3 overlap.

次に枠体２６に扉２５を吊り込む際の手段を図１５と図１６にて説明する。図１５と図１６は共に第一実施形態の構成の上部ヒンジ装置ａにて表記しているが、これらの吊り込み手段は第二実施形態の構成においても全く同様に可能である。まず上部ヒンジ装置ａと下部ヒンジ装置ｂの枠側ベースプレート１と中間プレート２を第一回転軸４にて連結し、さらに第一係止ピン１０や第二係止ピン１１等の機構部材も組み付けておき、枠体２６の吊元側上下位置に対面させた配置で装着する。また扉側プレート３のみを分離させた状態で扉２５の上下両吊元側に装着する。   Next, means for hanging the door 25 on the frame 26 will be described with reference to FIGS. 15 and 16 are both represented by the upper hinge device a having the configuration of the first embodiment, but these suspending means can be exactly the same in the configuration of the second embodiment. First, the frame side base plate 1 and the intermediate plate 2 of the upper hinge device a and the lower hinge device b are connected by the first rotating shaft 4, and mechanism members such as the first locking pin 10 and the second locking pin 11 are also assembled. In addition, the frame body 26 is mounted in an arrangement facing the vertical position on the suspension base side. Moreover, it mounts | wears with the up-and-down both suspension origin side of the door 25 in the state which isolate | separated only the door side plate 3. FIG.

扉２５を吊り込む動作としては、図１や図９に示すように下部ヒンジ装置ｂの中間プレート２に第二回転軸５を装着しておき、上下の中間プレート２間に扉２５を嵌め込むように配置し、扉２５下部に装着した扉側プレート３の第二回転軸挿入孔１４を下部ヒンジ装置ｂの第二回転軸５に差し込み、扉２５を起こして上部ヒンジ装置ａの中間プレート２と扉２５上部に装着した扉側プレート３を連結するとよい。この上部ヒンジ装置ａの中間プレート２と扉側プレート３との連結手段を図１５と図１６にて次に説明する。   As the operation of hanging the door 25, as shown in FIGS. 1 and 9, the second rotary shaft 5 is mounted on the intermediate plate 2 of the lower hinge device b, and the door 25 is fitted between the upper and lower intermediate plates 2. The second rotary shaft insertion hole 14 of the door side plate 3 mounted on the lower portion of the door 25 is inserted into the second rotary shaft 5 of the lower hinge device b, and the door 25 is raised to raise the intermediate plate 2 of the upper hinge device a. And the door side plate 3 mounted on the upper portion of the door 25 may be coupled. The connection means between the intermediate plate 2 and the door side plate 3 of the upper hinge device a will be described next with reference to FIGS.

まず図１５に示すようなつば部分を有し、根元が雄ねじ部分になっており、先端部分が軸芯として形成された第二回転軸５を設ける。次に上部ヒンジ装置ａの中間プレート２に第二回転軸挿入孔１４を設け、この孔に雌ねじ部分を設けておく。さらに扉２５上部に装着された扉側プレート３に第二回転軸５の軸芯部分がかろうじて差し込める程度の第二回転軸挿入孔１４を設けておく。次に上下の枠側ベースプレート１に対して両中間プレート２を所定角度位置にまで回転させた状態にし、扉側プレート３を装着した扉２５を所定角度位置より大きく開いた状態で両中間プレート２間に挿入し、下部ヒンジ装置ｂの中間プレート２の第二回転軸５に扉２５下部の扉側プレート３の第二回転軸挿入孔１４を嵌め込む。そして扉２５を起こして上部ヒンジ装置ａの中間プレート２の第二回転軸挿入孔１４と扉側プレート３の第二回転軸挿入孔１４の位置を合わせ、第二回転軸５を上側から両者に差し込み、第二回転軸５の雄ねじ部分を中間プレート２の雌ねじ部分に螺合して扉２５を枠体２６に吊り込む。   First, a second rotating shaft 5 having a collar portion as shown in FIG. 15, the root being a male screw portion, and a tip portion being formed as an axis is provided. Next, a second rotating shaft insertion hole 14 is provided in the intermediate plate 2 of the upper hinge device a, and a female screw portion is provided in this hole. Further, a second rotation shaft insertion hole 14 is provided in the door side plate 3 mounted on the upper portion of the door 25 so that the shaft core portion of the second rotation shaft 5 can be barely inserted. Next, both the intermediate plates 2 are rotated to a predetermined angular position with respect to the upper and lower frame side base plates 1, and both the intermediate plates 2 are opened with the door 25 having the door-side plate 3 mounted wider than the predetermined angular position. The second rotation shaft insertion hole 14 of the door side plate 3 below the door 25 is fitted into the second rotation shaft 5 of the intermediate plate 2 of the lower hinge device b. Then, the door 25 is raised and the second rotary shaft insertion hole 14 of the intermediate plate 2 of the upper hinge device a is aligned with the second rotary shaft insertion hole 14 of the door side plate 3, and the second rotary shaft 5 is moved from the upper side to the both. The door 25 is suspended from the frame body 26 by screwing the male screw portion of the second rotating shaft 5 into the female screw portion of the intermediate plate 2.

したがって第二回転軸５のつば部分の上面に十字孔や六角孔を設けておくか、つば部分自体を六角形状にし、スパナ等で回転できるようにしておくとよい。また、このとき扉２５と共に回転するのは第二回転軸５先端の軸芯部分になり、扉側プレート３の第二回転軸挿入孔１４との接触部分に摩耗性能のよい樹脂等のブッシュを嵌めておくとよい。また第二回転軸５を差し込んだ後で回転したり抜けたりしないように保持する手段は上記のようなねじ方式に限らず、軸芯部分を横方向からセットねじで別途固定する手段等どのような構成を用いてもよい。   Therefore, it is preferable to provide a cross hole or a hexagonal hole on the upper surface of the collar portion of the second rotating shaft 5 or to make the collar portion itself a hexagonal shape so that it can be rotated with a spanner or the like. Further, at this time, the shaft 25 rotates together with the door 25 at the tip of the second rotary shaft 5, and a bush of resin or the like having good wear performance is provided at the contact portion of the door side plate 3 with the second rotary shaft insertion hole 14. Fit it. The means for holding the second rotary shaft 5 so that it does not rotate or come out is not limited to the above-described screw system, and any means such as a means for separately fixing the shaft core portion with a set screw from the lateral direction. Various configurations may be used.

また図１６に示すように、上部ヒンジ装置ａの中間プレート２にＵ型形状の第二回転軸挿入溝２４を設け、上部扉側プレート３に第二回転軸５を装着しておき、下部ヒンジ装置ｂを連結した後で扉２５と共に第二回転軸５を横方向から第二回転軸挿入溝２４に嵌め込み、蓋部材を被せて抜けないように固定する手段を用いてもよい。また上部扉側プレート３に第二回転軸挿入溝２４を設け、中間プレート２に第二回転軸５を装着しておく逆の構成も可能である。したがって図１６に示す吊り込み手段は図１５の手段のように前準備としてあらかじめ上下の中間プレート２を回転させておく必要はない。つまり本発明のヒンジ装置は枠側ベースプレート１と中間プレート２と扉側プレート３から構成されるにもかかわらず、吊り込みに関しては扉側プレート３だけを分割した状態で扉２５の上下面に装着する点が特徴であり、扉２５に装着された扉側プレート３を上下の中間プレート２の間に嵌め込んだ後で簡単な手段により連結することにより容易な作業にて吊り込みを可能とすることができる。   Further, as shown in FIG. 16, a U-shaped second rotary shaft insertion groove 24 is provided in the intermediate plate 2 of the upper hinge device a, the second rotary shaft 5 is mounted on the upper door side plate 3, and the lower hinge After connecting the apparatus b, a means for fitting the second rotary shaft 5 together with the door 25 into the second rotary shaft insertion groove 24 from the lateral direction and covering the lid member so as not to be removed may be used. Further, a reverse configuration in which the second rotary shaft insertion groove 24 is provided in the upper door side plate 3 and the second rotary shaft 5 is mounted on the intermediate plate 2 is also possible. Therefore, the suspension means shown in FIG. 16 does not need to rotate the upper and lower intermediate plates 2 in advance as preparations like the means of FIG. That is, although the hinge device of the present invention is composed of the frame side base plate 1, the intermediate plate 2, and the door side plate 3, the hanging device is mounted on the upper and lower surfaces of the door 25 with only the door side plate 3 divided. It is characterized by the fact that the door side plate 3 mounted on the door 25 is fitted between the upper and lower intermediate plates 2 and then connected by simple means so that it can be suspended by an easy operation. be able to.
