本発明は以上に述べた実情に鑑み、障子を開閉するアームの操作を手動でも行える建具の提供を目的とする。   An object of the present invention is to provide a fitting that can manually operate an arm that opens and closes a shoji, in view of the above-described circumstances.

上記の課題を達成するために請求項1記載の発明による建具は、横軸回りに回転自在に支持した障子と、障子と非連結で設けられ、障子の開閉操作を行う開閉アームと、開閉アームの回転軸に固定して設けた駆動アームと、縦枠に沿ってスライドする開閉プレートと、開閉プレートと連動してスライドするロック部材と、開閉プレートとロック部材をスライドさせる操作部とを備え、駆動アームは係合軸を有し、開閉プレートは係合軸が係合する係合溝を有し、係合溝は開閉アームを障子閉位置で拘束する拘束部と、開閉アームが障子開の方向に回転するのを許容する非拘束部とを有し、係合軸が拘束部をスライドする間にロック部材が障子のロック受けと係合することを特徴とする。   In order to achieve the above object, a joinery according to the first aspect of the present invention includes a shoji supported so as to be rotatable about a horizontal axis, an open / close arm that is connected to the shoji and that opens / closes the shoji, and an open / close arm. A drive arm fixed to the rotating shaft of the first and second, an open / close plate that slides along the vertical frame, a lock member that slides in conjunction with the open / close plate, and an operation unit that slides the open / close plate and the lock member. The drive arm has an engagement shaft, the opening / closing plate has an engagement groove with which the engagement shaft engages, the engagement groove has a restraining portion that restrains the opening / closing arm in the closing position of the shoji, and the opening / closing arm has the shoji opening. And a non-restraining portion that allows rotation in a direction, and the lock member engages with the lock receiver of the shoji while the engaging shaft slides on the restraining portion.

請求項2記載の発明による建具は、横軸回りに回転自在に支持した障子と、障子と非連結で設けられ、障子の開閉操作を行う開閉アームと、開閉アームの回転軸に固定して設けた駆動アームと、縦枠に沿ってスライドする開閉プレートと、開閉プレートをスライドさせる操作部とを備え、開閉アームは回転自在であり、障子開方向に回転する方向に回転モーメントが働くようにしてあり、駆動アームは係合軸を有し、開閉プレートは係合軸が係合する係合溝を有し、係合溝は開閉アームを障子閉位置で拘束する拘束部と、開閉アームが障子開の方向に回転するのを許容する非拘束部とを有することを特徴とする。   The joinery according to the invention of claim 2 is provided with a shoji supported rotatably around the horizontal axis, an open / close arm that is not connected to the shoji, and opens and closes the shoji, and is fixed to the rotary shaft of the open / close arm. Drive arm, an open / close plate that slides along the vertical frame, and an operating portion that slides the open / close plate. The open / close arm is rotatable so that a rotational moment acts in the direction of rotation in the shoji opening direction. The drive arm has an engagement shaft, the opening / closing plate has an engagement groove with which the engagement shaft engages, the engagement groove has a restraining portion for restraining the opening / closing arm in the closing position of the shoji, and the opening / closing arm has the obstruction And an unconstrained portion that allows rotation in the opening direction.

請求項1記載の発明による建具は、開閉プレートに設けた係合溝に駆動アームの係合軸が係合しており、開閉プレートが縦枠に沿ってスライドすることで開閉アームが回動するため、開閉アームの操作が手動でも行える。しかも本建具は、開閉プレートと連動してスライドするロック部材を有し、係合溝は開閉アームを障子閉位置で拘束する拘束部と、開閉アームが障子開の方向に回転するのを許容する非拘束部とを有し、係合軸が拘束部をスライドする間にロック部材が障子のロック受けと係合するようにしたので、障子の閉鎖とロックを1アクションで行え、ロックが正確に行えると共に、障子等に無理な力が加わるのを防止できる。また、開閉アームは障子と非連結のため、操作が軽く行える。さらに、開閉プレートの係合溝に開閉アームが障子開の方向に回転するのを許容する非拘束部を有するので、操作が軽く行える。よって、電動で操作する場合も、モーターに負荷がかからない。   In the joinery according to the first aspect of the present invention, the engagement shaft of the drive arm is engaged with the engagement groove provided in the opening / closing plate, and the opening / closing arm rotates as the opening / closing plate slides along the vertical frame. Therefore, the opening / closing arm can be operated manually. In addition, this joinery has a lock member that slides in conjunction with the opening / closing plate, and the engaging groove allows the opening / closing arm to rotate in the opening direction of the shoji, and the restraining portion that restrains the opening / closing arm in the shoji closing position. Since the locking member engages with the lock receiver of the shoji while the engaging shaft slides on the restraining portion, the shoji can be closed and locked in one action, and the lock is accurate. In addition to being able to do so, it is possible to prevent excessive force from being applied to the shoji screen. In addition, since the open / close arm is not connected to the shoji, it can be operated lightly. Further, since the engaging groove of the opening / closing plate has a non-restraining portion that allows the opening / closing arm to rotate in the direction of opening the shoji, the operation can be performed lightly. Therefore, the motor is not loaded even when it is operated electrically.

請求項2記載の発明による建具は、開閉プレートに設けた係合溝に駆動アームの係合軸が係合しており、開閉プレートが縦枠に沿ってスライドすることで開閉アームが回動するため、開閉アームの操作が手動でも行える。しかも本建具は、開閉アームは回転自在であり、障子開方向に回転する方向に回転モーメントが働くようにしてあり、係合溝は開閉アームを障子閉位置で拘束する拘束部と、開閉アームが障子開の方向に回転するのを許容する非拘束部とを有するので、係合軸が拘束部から非拘束部に移行すると、開閉アームが自身に作用する回転モーメントによって障子開方向に回転するので、開閉アームの障子開方向への操作が軽く行える。また、開閉アームは障子と非連結のため、操作が軽く行える。さらに、開閉プレートの係合溝に開閉アームが障子開の方向に回転するのを許容する非拘束部を有するので、操作が軽く行える。よって、電動で操作する場合も、モーターに負荷がかからない。   In the fitting according to the second aspect of the present invention, the engagement shaft of the drive arm is engaged with the engagement groove provided in the opening / closing plate, and the opening / closing arm rotates when the opening / closing plate slides along the vertical frame. Therefore, the opening / closing arm can be operated manually. In addition, the open / close arm of the present fitting is rotatable, and a rotational moment is exerted in the direction of rotating in the shoji opening direction. Since it has a non-restraining part that allows it to rotate in the direction of opening the shoji, when the engagement shaft shifts from the restraining part to the non-restraining part, the opening / closing arm rotates in the shoji opening direction due to the rotational moment acting on itself. The opening and closing arm can be operated lightly in the direction of opening the shoji. In addition, since the open / close arm is not connected to the shoji, it can be operated lightly. Further, since the engaging groove of the opening / closing plate has a non-restraining portion that allows the opening / closing arm to rotate in the direction of opening the shoji, the operation can be performed lightly. Therefore, the motor is not loaded even when it is operated electrically.

以下、本発明の実施の形態を図面に基づいて説明する。図1〜図5は、本発明に係る建具の一実施形態であって、2連窓としたものを示している。この窓は、図5に示すように、上枠13と下枠14と左右の縦枠15,15と中間縦枠5とで枠16を構成し、左右の縦枠15,15と中間縦枠5との間の開口部に、それぞれ障子1,1を横軸17で回転自在に軸支してある。図2に示すように、横軸17は、障子1を中間高さより上部で偏心状態に軸支しており、障子1の上框の室内側には重り18が取付けてある。中間縦枠5の障子1よりも室内側には、障子1の開閉する範囲を規制したり、障子1を強制的に閉鎖ないし開放したりするための開閉アーム2が障子1と非連結で設けてある。図5に示すように、室内側から見て右側の縦枠15の下方位置には、障子1の開閉操作を行うためのハンドル7が設けてある。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 show an embodiment of a joinery according to the present invention, which is a double window. As shown in FIG. 5, the window includes a frame 16 composed of an upper frame 13, a lower frame 14, left and right vertical frames 15 and 15, and an intermediate vertical frame 5, and left and right vertical frames 15 and 15 and an intermediate vertical frame. The shojis 1 and 1 are pivotally supported by the horizontal shaft 17 in the openings between them 5. As shown in FIG. 2, the horizontal shaft 17 supports the shoji 1 in an eccentric state above the intermediate height, and a weight 18 is attached to the indoor side of the upper arm of the shoji 1. An opening / closing arm 2 for restricting the opening / closing range of the shoji 1 or forcibly closing / opening the shoji 1 is provided in the indoor side of the shoji 1 of the intermediate vertical frame 5 so as not to be connected to the shoji 1. It is. As shown in FIG. 5, a handle 7 for opening / closing the shoji 1 is provided at a position below the vertical frame 15 on the right side when viewed from the indoor side.

中間縦枠5の内部には、図1,3に示すように、ベース19が取付けてあり、ベース19には水平な回転軸3がベアリング20により回転自在に支持されており、回転軸3の左右両端部に開閉アーム2,2が固定して設けてあり、回転軸3の中間部には駆動アーム4が固定して設けてある。回転軸3は、障子1の横軸17と同じ高さに設けてある。また、ベース19にはレール21が垂直方向に設けてあり、該レール21に案内して開閉プレート6が垂直方向にスライド自在に設けてある。   As shown in FIGS. 1 and 3, a base 19 is attached inside the intermediate vertical frame 5, and a horizontal rotary shaft 3 is rotatably supported by a bearing 20 on the base 19. Opening and closing arms 2 and 2 are fixedly provided at both left and right end portions, and a driving arm 4 is fixedly provided at an intermediate portion of the rotating shaft 3. The rotary shaft 3 is provided at the same height as the horizontal shaft 17 of the shoji 1. A rail 21 is provided in the base 19 in the vertical direction, and the open / close plate 6 is slidably provided in the vertical direction while being guided by the rail 21.

開閉アーム2は、図1に示すように、上向きにのびる閉鎖アーム22と、室内側の斜め下方に向けてのびる蹴り出しアーム23とを、への字形を成すように組み合わせたものとなっている。各アーム22,23の先端部には、ゴムローラー24が取付けてある。開閉アーム2は、上記のような形状・姿勢になっていることで、図13に示すように、回転に制約を受けないとすれば図中の2点鎖線で示す状態まで回転しようとするから、開閉アーム2には閉鎖アーム22が室内側に、蹴り出しアーム23が室外側にそれぞれ回転する方向、すなわち障子開の方向に、回転モーメントMが働いている。
駆動アーム4は、図1に示すように、先端部に係合軸8が設けてあり、この係合軸8が開閉プレート2の係合溝9に係合することで、開閉アーム2の回転が規制されている。駆動アーム4は、下面側に斜めに枝分かれしてのびる係止部25を有している。
As shown in FIG. 1, the open / close arm 2 is a combination of a closing arm 22 extending upward and a kicking arm 23 extending obliquely downward on the indoor side so as to form a square shape. . A rubber roller 24 is attached to the tip of each arm 22, 23. Since the opening / closing arm 2 has the shape and posture as described above, as shown in FIG. 13, if it is not restricted by rotation, it will rotate to the state shown by the two-dot chain line in the figure. The opening / closing arm 2 has a rotational moment M acting in the direction in which the closing arm 22 rotates indoors and the kicking arm 23 rotates outward, that is, in the direction of opening the shoji.
As shown in FIG. 1, the drive arm 4 is provided with an engagement shaft 8 at the tip, and the engagement shaft 8 engages with the engagement groove 9 of the opening / closing plate 2, thereby rotating the opening / closing arm 2. Is regulated. The drive arm 4 has a locking portion 25 that branches obliquely on the lower surface side.

開閉プレート6は、図1に示すように、上部に駆動アーム4の係合軸8が係合する係合溝9を有している。係合溝9は、上部に縦枠5に沿って垂直方向にのびる一定幅の拘束部10を有し、拘束部10の下方には室外側に傾斜した斜辺部26と、室外側縦辺部27と、水平な底辺部28と、拘束部10の室内側辺と連続する室内側縦辺部29とで囲まれた非拘束部11とを有している。拘束部10は、係合軸8の直径よりも少し広い溝幅で形成してあり、拘束部10に係合軸8が位置する間は、駆動アーム4は室外側の斜め下向きの一定の角度に保持され、開閉アーム2は閉鎖アーム22が障子1の竪框の横軸17より上側を室外側に押して、障子1を閉鎖状態に保持する。非拘束部11では、係合軸8は移動可能となり、それに伴って駆動アーム4及び開閉アーム2が回動する。さらに開閉プレート6は、係合溝9の下方に係合ピン30を有している。   As shown in FIG. 1, the opening / closing plate 6 has an engagement groove 9 in the upper portion for engaging the engagement shaft 8 of the drive arm 4. The engaging groove 9 has a constraining portion 10 having a constant width extending in the vertical direction along the vertical frame 5 at the upper portion, and an oblique side portion 26 inclined to the outdoor side below the constraining portion 10 and an outdoor side vertical side portion. 27, a horizontal bottom portion 28, and an unconstrained portion 11 surrounded by an indoor side vertical side portion 29 continuous with the indoor side side of the constraining portion 10. The restraint portion 10 is formed with a groove width slightly wider than the diameter of the engagement shaft 8, and the drive arm 4 is inclined at a certain angle downward on the outdoor side while the engagement shaft 8 is positioned on the restraint portion 10. The opening / closing arm 2 holds the shoji 1 in a closed state by the closing arm 22 pushing the upper side of the lateral shaft 17 of the shoji 1 to the outdoor side. In the non-restraining portion 11, the engagement shaft 8 can move, and the drive arm 4 and the opening / closing arm 2 rotate accordingly. Further, the opening / closing plate 6 has an engagement pin 30 below the engagement groove 9.

下枠14の上面には、図2,4に示すように、横スライドバー31が下枠14の長手方向に沿ってスライド可能に設けてあり、横スライドバー31には障子1下部に設けたロック受け32に係合して障子1をロックするロックピン12が設けてある。横スライドバー31は、中間縦枠5と下枠14とのコーナー部に設けたコーナードライブ33により、開閉プレート6と連結してある。コーナードライブ33は、L型に曲がった筒状のガイド部材34と、ガイド部材34内に挿通した摺動部材35とを有するもので、摺動部材35がガイド部材34にガイドされた状態で摺動することで、押し引き力を直角に伝達できるものであり、摺動部材35の一端部が開閉プレート6の下端部に連結され(図1参照)、摺動部材35の他端部が連結具36を介して横スライドバー31に連結してある(図4参照)。そのため、開閉プレート6と横スライドバー31とは連動してスライドする。
図5に示すように、横スライドバー31の端部は別のコーナードライブ37によりハンドル7と連結してあり、ハンドル7を回転操作することで横スライドバー31がスライドするようになっている。
As shown in FIGS. 2 and 4, a horizontal slide bar 31 is provided on the upper surface of the lower frame 14 so as to be slidable along the longitudinal direction of the lower frame 14, and the horizontal slide bar 31 is provided below the shoji 1. A lock pin 12 that engages with the lock receiver 32 to lock the shoji 1 is provided. The horizontal slide bar 31 is connected to the opening / closing plate 6 by a corner drive 33 provided at a corner portion between the intermediate vertical frame 5 and the lower frame 14. The corner drive 33 includes a cylindrical guide member 34 bent into an L shape and a sliding member 35 inserted into the guide member 34. The sliding member 35 is slid in a state where the sliding member 35 is guided by the guide member 34. By moving, the pushing and pulling force can be transmitted at a right angle, one end of the sliding member 35 is connected to the lower end of the opening / closing plate 6 (see FIG. 1), and the other end of the sliding member 35 is connected. It connects with the horizontal slide bar 31 via the tool 36 (refer FIG. 4). Therefore, the opening / closing plate 6 and the horizontal slide bar 31 slide in conjunction with each other.
As shown in FIG. 5, the end of the horizontal slide bar 31 is connected to the handle 7 by another corner drive 37, and the horizontal slide bar 31 is slid by rotating the handle 7.

次に、本建具の動作について説明する。図1に示すように、障子1が閉鎖した状態のときには、開閉プレート6は一番下に下がった位置にあって、駆動アーム4の係合軸8は開閉プレート6の係合溝9の拘束部10の上部に位置しており、このとき開閉アーム2は閉鎖アーム22が障子1に当接して障子1を閉鎖状態に保持している。またこのとき、横スライドバー31は一番右側にスライドした位置にあって、図4に示すように、ロックピン12が障子1のロック受け32と係合している。
ハンドル7を障子開き側に操作すると、横スライドバー31は左側に向けてスライドし、これに連動して開閉プレート6が上にスライドする。これによりロックピン12がロック受け32から外れ、駆動アーム4の係合軸8は、図11(b)に示すように、開閉プレート6の拘束部10内を下向きに移動する。その後、図11(c)と図6に示すように、係合軸8が拘束部10から外れて非拘束部11に移行すると、先に述べたように開閉アーム2に障子開の方向に回転モーメントMが働いているために、回転軸3が駆動アーム4及び開閉アーム2共々、障子開の方向(図6中の時計方向)に回転する。その後、開閉プレート6が上昇するにつれて、係合軸8が非拘束部11の斜辺部26に係止しながら、駆動アーム4及び開閉アーム2が障子開の方向に回転する。
その後、図11(d)に示すように、係合軸9が非拘束部11内の室外側に突き出た突部の先端部(自然換気拘束部38)に位置すると、駆動アーム4はほぼ水平な向きとなり、このとき開閉アーム2は図7に示すように、閉鎖アーム22が斜め上向きの状態となり、蹴り出しアーム23はほぼ真下に向いた状態になる。このとき障子1は、閉鎖状態から閉鎖アーム22に当接するまでの範囲で、風の力で自動的にスイングする(自然換気状態)。
この状態からさらに開閉プレート6を上にスライドすると、図11(d)〜(e)に示すように、開閉プレート6の上昇に伴って係合軸8が非拘束部11の底辺部28に係合しながら室内側に移動し、それに伴って駆動アーム4と開閉アーム2が障子開の方向に回転し、図8に示すように、蹴り出しアーム23が障子1の横軸17より下側を押して障子1を開放状態に保持する(排煙状態)。
Next, the operation of the present joinery will be described. As shown in FIG. 1, when the shoji 1 is closed, the opening / closing plate 6 is in the lowest position, and the engaging shaft 8 of the drive arm 4 is restrained by the engaging groove 9 of the opening / closing plate 6. At this time, the opening / closing arm 2 holds the shoji 1 in a closed state with the closing arm 22 in contact with the shoji 1. At this time, the horizontal slide bar 31 is in the position slid to the rightmost side, and the lock pin 12 is engaged with the lock receiver 32 of the shoji 1 as shown in FIG.
When the handle 7 is operated to open the shoji, the horizontal slide bar 31 slides toward the left side, and the opening / closing plate 6 slides up in conjunction with this. As a result, the lock pin 12 is disengaged from the lock receiver 32, and the engagement shaft 8 of the drive arm 4 moves downward in the restraining portion 10 of the open / close plate 6 as shown in FIG. Thereafter, as shown in FIGS. 11C and 6, when the engaging shaft 8 is disengaged from the restraining portion 10 and moves to the non-restraining portion 11, the opening / closing arm 2 rotates in the direction of opening the shoji as described above. Since the moment M is working, the rotating shaft 3 rotates in the direction to open the shoji (clockwise in FIG. 6) together with the drive arm 4 and the opening / closing arm 2. Thereafter, as the opening / closing plate 6 moves upward, the drive shaft 4 and the opening / closing arm 2 rotate in the direction of opening the shoji, while the engaging shaft 8 is engaged with the oblique side portion 26 of the non-constraining portion 11.
Thereafter, as shown in FIG. 11 (d), when the engagement shaft 9 is positioned at the distal end portion (natural ventilation restraint portion 38) of the projection protruding outside the inside of the non-restraint portion 11, the drive arm 4 is substantially horizontal. At this time, as shown in FIG. 7, the opening / closing arm 2 is in a state in which the closing arm 22 is obliquely upward and the kicking arm 23 is substantially downward. At this time, the shoji 1 automatically swings by the force of wind in the range from the closed state to the contact with the closed arm 22 (natural ventilation state).
When the open / close plate 6 is further slid from this state, the engagement shaft 8 is engaged with the bottom side 28 of the non-restraining portion 11 as the open / close plate 6 is lifted, as shown in FIGS. Then, the drive arm 4 and the opening / closing arm 2 rotate in the direction of opening the shoji, and as shown in FIG. 8, the kick-out arm 23 moves below the horizontal shaft 17 of the shoji 1. Press to hold the shoji 1 open (smoke exhaust state).

次に、障子1を蹴り出しアーム23で強制的に開放した状態から障子1を閉鎖する際の動きについて説明する。障子1を蹴り出しアーム23で強制的に開放した状態では、図12(a)に示すように、開閉プレート6が一番上に上がった位置にあって、係合軸8は非拘束部11の室内側のコーナー部に位置している。ハンドル7を障子閉じ側に操作すると、開閉プレート6は下にスライドし、図12(b)に示すように、開閉プレート6に設けた係合ピン30が駆動アーム4の係止部25に係止して下に押すため、駆動アーム4と開閉アーム2は障子閉じ側(図中の反時計方向)に回転し、それに伴って障子1が徐々に閉まる。仮に係合ピン30と係止部25が無かったとすると、開閉アーム2には障子開の方向に回転するように回転モーメントMが働いているため、開閉プレート6が下降しても開閉アーム2が障子閉じ側に回転しないおそれがあるが、このように係合ピン30と係止部25を設けることで、確実に開閉アーム2を障子閉じ側に回転させられる。
その後、図12(c)〜(e)に示すように、開閉プレート6が下降するにつれて、係合軸8が非拘束部11の斜辺部26に係止しながら駆動アーム4及び開閉アーム2が障子閉じ側に回転する。その後、図12(f)に示すように、係合軸8が拘束部10に移行した時点で開閉アーム2が障子1を閉め切る状態となり、この時点では図10に示すように、ロックピン12が障子1のロック受け32と係合していない。その後、図12(g)に示すように、係合軸8が拘束部10内をスライドする間に、ロックピン12が障子1のロック受け32と係合する。
Next, the movement when closing the shoji 1 from the state in which the shoji 1 is kicked out and forcibly opened by the arm 23 will be described. In the state in which the shoji 1 is forcibly opened by the kicking arm 23, as shown in FIG. 12 (a), the opening / closing plate 6 is at the highest position, and the engagement shaft 8 is not connected to the unconstrained portion 11. Located in the corner of the room. When the handle 7 is operated to close the shoji, the opening / closing plate 6 slides downward, and the engaging pin 30 provided on the opening / closing plate 6 is engaged with the locking portion 25 of the driving arm 4 as shown in FIG. In order to stop and push down, the drive arm 4 and the opening / closing arm 2 rotate to the shoji closing side (counterclockwise in the figure), and the shoji 1 gradually closes accordingly. If the engagement pin 30 and the locking portion 25 are not provided, the opening / closing arm 2 has a rotational moment M so as to rotate in the opening direction of the shoji. Although there is a possibility that it does not rotate toward the shoji closing side, the opening / closing arm 2 can be reliably rotated to the shoji closing side by providing the engaging pin 30 and the locking portion 25 in this way.
Thereafter, as shown in FIGS. 12C to 12E, as the opening / closing plate 6 is lowered, the driving shaft 4 and the opening / closing arm 2 are moved while the engaging shaft 8 is locked to the oblique side portion 26 of the non-constraining portion 11. Rotate to the shoji closing side. Thereafter, as shown in FIG. 12 (f), when the engagement shaft 8 moves to the restraining portion 10, the opening / closing arm 2 is in a state of closing the shoji 1, and at this time, as shown in FIG. Is not engaged with the lock receiver 32 of the shoji 1. Thereafter, as shown in FIG. 12 (g), the lock pin 12 engages with the lock receiver 32 of the shoji 1 while the engagement shaft 8 slides inside the restraining portion 10.

以上に述べたように本建具は、開閉プレート6に設けた係合溝9に駆動アーム4の係合軸8が係合しており、開閉プレート6が縦枠5に沿ってスライドすることで開閉アーム2が回動するため、開閉アーム2の操作がハンドル7を介して手動で行うことができる。しかも本建具は、開閉プレート2と連動してスライドするロックピン12を有し、係合溝9は開閉アーム2を障子閉位置で拘束する拘束部10と、開閉アーム2が障子開の方向に回転するのを許容する非拘束部11とを有し、係合軸8が拘束部10をスライドする間にロックピン12が障子1のロック受け32と係合してロックがかかるようにしたので、障子1の閉鎖とロックをハンドル7を操作するだけで1アクションで連続して行え、ロックが正確に行えると共に、障子1等に無理な力が加わるのを防止できる。
また本建具は、開閉アーム2は回転自在であり、障子開方向に回転する方向に回転モーメントMが働くようにしてあり、係合溝9は開閉アーム2を障子閉位置で拘束する拘束部10と、開閉アーム2が障子開の方向に回転するのを許容する非拘束部11とを有するので、係合軸9が拘束部10から非拘束部11に移行すると、開閉アーム2が自身に作用する回転モーメントMによって障子開方向に回転するので、開閉アーム2の障子開方向への操作が軽く行える。
また、開閉アーム2は障子1と非連結のため、操作が軽く行える。さらに、開閉プレート6の係合溝8に開閉アーム2が障子開の方向に回転するのを許容する非拘束部11を有するので、操作が軽く行える。
さらに本建具は、開閉アーム2が障子1を強制的に開く位置にあるときに駆動アーム4と係合し、開閉アーム2を障子閉じ側に駆動可能な係合ピン30を開閉プレート6に設けたので、障子1を強制的に開いた位置から開閉アーム2を障子閉じ側に確実に回転させられる。
さらに本建具は、開閉プレート6の係合溝9に開閉アーム2を自然換気の位置で拘束する自然換気拘束部38(図7参照)を有するので、開閉アーム2を自然換気の角度に保持できる。
As described above, in the present fitting, the engagement shaft 8 of the drive arm 4 is engaged with the engagement groove 9 provided in the opening / closing plate 6, and the opening / closing plate 6 slides along the vertical frame 5. Since the opening / closing arm 2 rotates, the opening / closing arm 2 can be manually operated via the handle 7. Moreover, this joinery has a lock pin 12 that slides in conjunction with the opening / closing plate 2, the engagement groove 9 is a restraining portion 10 that restrains the opening / closing arm 2 in the shoji closed position, and the opening / closing arm 2 is in the direction of shoji opening. Since the lock pin 12 is engaged with the lock receiver 32 of the shoji 1 and is locked while the engaging shaft 8 slides on the restricting portion 10, the lock pin 12 is engaged and locked. The shoji 1 can be closed and locked continuously by only operating the handle 7 in one action, so that the shoji 1 can be accurately locked, and an excessive force can be prevented from being applied to the shoji 1 and the like.
Further, in the present fitting, the opening / closing arm 2 is rotatable, a rotation moment M is applied in a direction rotating in the shoji opening direction, and the engaging groove 9 is a restraining portion 10 for restraining the opening / closing arm 2 in the shoji closing position. And the non-restraining portion 11 that allows the opening / closing arm 2 to rotate in the direction of opening the shoji, so that when the engagement shaft 9 moves from the restraining portion 10 to the non-constraining portion 11, the opening / closing arm 2 acts on itself. Since the rotating moment M is rotated in the opening direction of the shoji, the opening / closing arm 2 can be lightly operated in the opening direction of the shoji.
Further, since the open / close arm 2 is not connected to the shoji 1, it can be operated lightly. Furthermore, since the engaging groove 8 of the opening / closing plate 6 has the non-restraining portion 11 that allows the opening / closing arm 2 to rotate in the direction of opening the shoji, the operation can be performed lightly.
Furthermore, the present fitting is provided with an engagement pin 30 on the opening / closing plate 6 that engages with the driving arm 4 when the opening / closing arm 2 is in a position for forcibly opening the shoji 1 and can drive the opening / closing arm 2 to the closing side of the shoji. Therefore, the opening / closing arm 2 can be reliably rotated from the position where the shoji 1 is forcibly opened to the shoji closing side.
Furthermore, since the present fitting has a natural ventilation restraining portion 38 (see FIG. 7) for restraining the open / close arm 2 at the natural ventilation position in the engagement groove 9 of the open / close plate 6, the open / close arm 2 can be held at the natural ventilation angle. .

上述の実施形態は、開閉アーム2の操作をハンドル7により手動で操作するものであったが、開閉アーム2の操作を電動で行うこともできる。図14は、電動の場合を示している。この場合、下枠14に横スライドバー31をスライド駆動する電動モーター39を設置し、枠外に制御ユニット40と操作スイッチ41を設置する。操作スイッチ41には、例えば「開」、「閉」、「排煙」の各ボタン42a,42b,42cを設け、各ボタン42a,42b,42cを押すと電動モーター39が駆動して横スライドバー31と開閉プレート6が所定の位置にスライドし、自然換気状態、閉鎖状態、排煙状態にすることができる。
本建具は、先に述べたように、開閉アーム2が障子1と非連結であることや、開閉プレート6の係合溝8に開閉アーム2が障子開の方向に回転するのを許容する非拘束部11を有することにより、操作が軽く行えることから、電動で操作する場合に電動モーター39に負荷がかからない。
In the above-described embodiment, the operation of the open / close arm 2 is manually operated by the handle 7, but the operation of the open / close arm 2 can also be performed electrically. FIG. 14 shows the case of electric drive. In this case, an electric motor 39 that slides the horizontal slide bar 31 is installed on the lower frame 14, and a control unit 40 and an operation switch 41 are installed outside the frame. The operation switch 41 is provided with, for example, “open”, “closed”, and “smoke exhaust” buttons 42a, 42b, and 42c. When the buttons 42a, 42b, and 42c are pressed, the electric motor 39 is driven to move the horizontal slide bar. 31 and the opening-and-closing plate 6 slide to a predetermined position, and can be in a natural ventilation state, a closed state, and a smoke exhaustion state.
As described above, the present fitting is not connected to the opening / closing arm 2 and is not connected to the shoji 1 or allows the engaging groove 8 of the opening / closing plate 6 to rotate the opening / closing arm 2 in the opening direction of the shoji. Since the operation can be performed lightly by having the restraining portion 11, no load is applied to the electric motor 39 when operated electrically.
