When the shoji 7 is opened, the movable body 91 is separated from the contact piece 92 and is slid to the outdoor side by the spring 95, and the engagement protrusion 98 is fitted in any of the first, second, and third recesses 97a, 97b, and 97c. This restricts the operating rod 14a from moving.
The third recess 97a is longer than the engagement protrusion 98 so that the engagement protrusion 98 can move by a predetermined stroke.

次に、窓の作動を説明する。
ハンドル１６が下向きにある障子７を閉じた状態では、図１０に示す第１ピン５６と第２ピン５７は第１位置Ｉとなって第１ピン５６が係合凹溝５４と離れ、第２ピン５７が係合長溝５５内に位置している。安全装置Ｇの係合突起９８は、第１凹部９７ａと対向する第１位置Ｉ、障子支承装置Ｄの係合部材８９は縦溝８２の上部に嵌合した第１位置Ｉ、係合ピン１９は縦ガイド溝２０ｅの下部に嵌合した第１位置Ｉとなっている。 Next, the operation of the window will be described.
In the state where the shoji 7 with the handle 16 facing downward is closed, the first pin 56 and the second pin 57 shown in FIG. 10 are in the first position I, and the first pin 56 is separated from the engagement groove 54, and the second The pin 57 is located in the engagement long groove 55. The engagement protrusion 98 of the safety device G is in the first position I facing the first recess 97a, the engagement member 89 of the shoji support device D is in the first position I fitted in the upper part of the longitudinal groove 82, and the engagement pin 19 Is the first position I fitted in the lower part of the vertical guide groove 20e.

この状態よりハンドル１６を第１位置Ｘまで回転すると作動杆１４ａは下方に摺動してコーナー連結部材１５ａを介して第１作動杆２０を左方に移動し、連動杆２１、第２作動杆２２、可動杵４８が同時に左方に移動して第１、第２ピン５６，５７は第２位置ＩＩに移動する。
これにより係合部材８９は切欠部８３より受けブロック８０の室内側に突出できるようになる。他方、係合ピン１９は縦ガイド溝２０ｅに沿って上方に摺動して切欠開口部２０ｆまで達せずに縦ガイド溝２０ｅに臨む第２位置ＩＩとなり、障子７の一方の縦枠４は係合ピン１９を介して受け片２０ｄに係合保持される。また、係合部材８９は切欠部８３より離脱する。
この状態から、ハンドル１６を持って室内側に引くことで障子７がヒンジ装置Ｂの縦軸６２と蝶番２０の縦ピン２０ｂを介して室内側に回動した内開き状態となる。 When the handle 16 is rotated from this state to the first position X, the operating rod 14a slides downward and moves the first operating rod 20 to the left via the corner connecting member 15a. 22. The movable rod 48 simultaneously moves to the left, and the first and second pins 56 and 57 move to the second position II.
As a result, the engaging member 89 can protrude from the notch 83 to the inside of the receiving block 80. On the other hand, the engagement pin 19 slides upward along the vertical guide groove 20e and reaches the second position II facing the vertical guide groove 20e without reaching the notch opening 20f, and one vertical frame 4 of the shoji 7 is engaged. It is engaged and held by the receiving piece 20d through the mating pin 19. Further, the engaging member 89 is detached from the notch 83.
From this state, by pulling the handle 16 to the indoor side, the shoji 7 is in an open state in which the shoji 7 is rotated to the indoor side via the longitudinal axis 62 of the hinge device B and the vertical pin 20b of the hinge 20.

この時、安全装置Ｇの係合突起９８は縦溝９６に沿って第２凹部９７ｂと対向する第２位置ＩＩに移動し、障子支承部材Ｄの係合部材８９は縦溝８２の切欠部８３と対向した第２位置ＩＩに移動する。
障子７が回動すると、安全装置Ｇの可動体９１がバネ９５で室外側に押されて係合突起９８に第２凹部９７ｂが嵌合し、作動杆１４ａの移動を規制するのでハンドル１６を回動することができずに、障子７を室内側に回動した状態でハンドル１６を回動して係合ピン１９が移動できないので、誤って係合ピン１９が縦ガイド溝２０ｅより外れたりすることがなく安全である。
つまり、障子７を室内側に回動した状態で係合ピン１９が縦ガイド溝２０ｅより外れると障子７の上部が窓枠１に対してフリーとなって障子７が室内側に外れることがある。
前述の状態より障子７を閉じると安全装置Ｇの可動体９１が当片９２に当接してバネ９５に抗して室内側に押されて係合突起９８が縦溝９６に位置する。 At this time, the engagement protrusion 98 of the safety device G moves along the vertical groove 96 to the second position II facing the second recess 97b, and the engagement member 89 of the shoji support member D is notched 83 of the vertical groove 82. And move to a second position II opposite to.
When the shoji 7 is rotated, the movable body 91 of the safety device G is pushed to the outdoor side by the spring 95, the second recess 97b is fitted to the engagement protrusion 98, and the movement of the operating rod 14a is restricted. Since the engagement pin 19 cannot be moved by rotating the handle 16 in a state in which the shoji 7 is rotated indoors without being able to rotate, the engagement pin 19 may be accidentally detached from the vertical guide groove 20e. Safe without having to.
That is, when the engagement pin 19 is removed from the vertical guide groove 20e with the shoji 7 turned to the indoor side, the upper portion of the shoji 7 may be free with respect to the window frame 1 and the shoji 7 may be removed to the indoor side. .
When the shoji 7 is closed from the above-mentioned state, the movable body 91 of the safety device G comes into contact with the contact piece 92 and is pushed indoors against the spring 95, so that the engaging projection 98 is positioned in the vertical groove 96.

これよりハンドル１６を更に回動すると前述と同様に可動杵４８が左方に移動して第１ピン５６が係合凹溝５４に嵌合する第３位置ＩＩＩ、第２ピン５７が係合長溝５５の斜面５５ａに接する第３位置ＩＩＩとなる。
障子支承部材Ｄの係合部材８９は切欠部８３より外れた第３位置ＩＩＩとなると共に、係合ピン１９は切欠開口部２０ｆに対向する第３位置ＩＩＩとなって一方の縦框１０は窓枠１の一方の縦枠４に対してフリーとなる。これより更にハンドル１６を回動すると第２ピン５７が斜面５５ａを押してレバー５１がピン５２を中心として回動され、かつ第１ピン５６も係合凹溝５４を押して回動される。
これにより、レバー５１を支持している障子７の上框４が室内側に押されて傾倒する。この時第１ピン５６は係合凹溝５４の半円形部分５４ｂに嵌合していると共に、係合ピン１９は切欠開口部２０ｆより室内側に離脱する。
すなわち、障子７はヒンジ装置Ｂの横軸６４の中心軸と障子支承装置Ｄの係合部材８９の中心軸を中心として傾動すると共に、係合ピン１９は切欠開口部２０ｆより室内側に離脱する。 When the handle 16 is further rotated, the movable rod 48 moves to the left as described above, and the third position III where the first pin 56 is fitted into the engaging groove 54 and the second pin 57 are the engaging long groove. The third position III is in contact with the 55 slope 55a.
The engaging member 89 of the shoji support member D is in the third position III disengaged from the notch 83, and the engaging pin 19 is in the third position III facing the notch opening 20f. It becomes free with respect to one vertical frame 4 of the frame 1. When the handle 16 is further rotated, the second pin 57 pushes the inclined surface 55a, the lever 51 is pivoted about the pin 52, and the first pin 56 is also pivoted by pushing the engaging groove 54.
As a result, the upper arm 4 of the shoji 7 supporting the lever 51 is pushed inward and tilted. At this time, the first pin 56 is fitted in the semicircular portion 54b of the engaging groove 54, and the engaging pin 19 is detached from the notch opening 20f to the indoor side.
That is, the shoji 7 is tilted about the central axis of the horizontal shaft 64 of the hinge device B and the central axis of the engaging member 89 of the shoji support device D, and the engaging pin 19 is separated from the notch opening 20f to the indoor side. .

そして更にハンドル１６を回動して可動杵４８を左方に移動すると第１ピン５６がレバー５１をピン５２を中心として更に回動し、レバー５１のピン５３がアーム４２の長孔４２ａに摺動しながら上框４を室内側に順次押して障子７を室内側に所定角度傾倒する。
この時、アーム４２のピン４３は横材４９のガイド長孔４１に沿って摺動すると共に、リンク４４に対して揺動する。
他方、安全装置Ｇの係合突起９８は第３凹部９７ｃの上部に対向する第３位置ＩＩＩとなり、障子７を室内側に傾動した状態では係合突起９８が第３凹部９７ｃに嵌合しているから、係合突起９８は第３凹部９７ｃの範囲内でしか移動できず、ハンドル１６を回動して障子支承装置Ｄの係合部材８９が切欠部８３と対向する第２位置ＩＩまでは移動できないから誤ってハンドル１６を回動しても障子７が外れることがない。 When the handle 16 is further rotated to move the movable rod 48 to the left, the first pin 56 further rotates the lever 51 around the pin 52, and the pin 53 of the lever 51 slides into the long hole 42a of the arm 42. While moving, the upper arm 4 is sequentially pushed toward the room side, and the shoji 7 is tilted toward the room side by a predetermined angle.
At this time, the pin 43 of the arm 42 slides along the guide long hole 41 of the cross member 49 and swings with respect to the link 44.
On the other hand, the engagement protrusion 98 of the safety device G is at the third position III facing the upper portion of the third recess 97c, and the engagement protrusion 98 is fitted into the third recess 97c in a state where the shoji 7 is tilted indoors. Therefore, the engagement protrusion 98 can move only within the range of the third recess 97c, and the handle 16 is rotated to the second position II where the engagement member 89 of the shoji support device D faces the notch 83. Since it cannot move, the shoji 7 does not come off even if the handle 16 is rotated by mistake.

また、障子７を閉じる時にはハンドル１６を反対方向に回動して作動杆１４を上方に移動させる。これにより、可動杵４８とともに第１ピン５６が矢印方向に移動してレバー５１をピン５２を中心として矢印方向に回動し、ピン５３を介してアーム４２を上框４側に回動することになるから上框が窓枠１側に移動して障子７が閉じ動作する。

以下、本発明の実施の形態による多方向開放窓について、図面を参照しながら説明する。なお、多方向開放窓に機構については、ハンドルの向き、操作などの相違はあるが、基本的に従来例と同じであるので、その詳細な説明を省略する。また、従来例による多方向窓と同一部材については同一の符号を付して説明する。
図１は、本発明に係わる多方向開放窓を示し、多方向開放窓の窓枠１は、上枠２と下枠３と一方の縦枠４と他方の縦枠５とで四角形状に形成されている。窓枠１の内側に配設されている障子７は、上框８と下框９と一方の縦框１０と他方の縦框１１で四角形状枠に形成され、その内部にガラス１２が装着されている。障子７の周囲には、作動杵１４が摺動自在に配設されている。 Hereinafter, a multidirectional open window according to an embodiment of the present invention will be described with reference to the drawings. The mechanism of the multi-directional opening window is basically the same as that of the conventional example, although there are differences in the direction of the handle, operation, etc., and detailed description thereof will be omitted. The same members as those of the conventional multi-directional window will be described with the same reference numerals.
FIG. 1 shows a multidirectional open window according to the present invention, and the window frame 1 of the multidirectional open window is formed in a square shape with an upper frame 2, a lower frame 3, one vertical frame 4, and the other vertical frame 5. Has been. The shoji 7 disposed inside the window frame 1 is formed into a quadrangular frame with an upper eave 8, a lower eave 9, one vertical eave 10, and the other vertical eave 11, and a glass 12 is mounted therein. ing. An operating rod 14 is slidably disposed around the shoji 7.

障子７の一側部における中間位置には、作動杵のラック部と噛合するピニオンギヤ（図示せず）が取付けられたハンドル１６が取付けられている。ハンドル１６の回転方向に沿って、作動杵１４が摺動する。
図２は、ハンドル１６の位置と障子の作動状態を示す。
図２のＡは、ハンドル１６を上方に向けた状態であり、下枠３を回動軸として障子７を内倒しにでき、作動杵１４の摺動位置は第１位置を示す。図２のＢは、ハンドル１６を横に向けた状態であり、障子７を内開きにでき、作動杵１４の摺動位置は第２位置を示す。図２のＣは、障子７がハンドル１６を下方に向けた状態であり、窓の施錠状態である。 A handle 16 to which a pinion gear (not shown) that meshes with the rack portion of the operating rod is attached is attached to an intermediate position on one side of the shoji 7. The operating rod 14 slides along the rotation direction of the handle 16.
FIG. 2 shows the position of the handle 16 and the operating state of the shoji.

FIG. 2B shows a state in which the handle 16 is directed to the side, the shoji 7 can be opened inward, and the sliding position of the operating rod 14 indicates the second position. FIG. 2C shows a state in which the shoji 7 has the handle 16 facing downward, and is a locked state of the window.

図３は本発明の第１安全装置Ｊであり、図３のＡは障子７の外周部から安全装置Ｊを見た平面図、図３のＢは障子７の内側から安全装置Ｊを見た背面図、図３のＣは障子７の側面から見た側面図である。
安全装置Ｊは、障子７の縦框１１に固定した表面板２１を設け、縦框５と表面板２１との間に作動杵１４が摺動可能に配設されている。
表面板２１の表面側には、揺動レバーとしてのトリガー２２が揺動軸２３を中心に回動可能に取付けられている。トリガー２２の揺動軸２３の裏側にはリブ２３ａが形成されている。 FIG. 3 shows the first safety device J of the present invention. FIG. 3A is a plan view of the safety device J viewed from the outer periphery of the shoji 7, and FIG. 3B is the safety device J viewed from the inside of the shoji 7. A rear view and C in FIG. 3 are side views of the shoji 7 as viewed from the side.
The safety device J is provided with a surface plate 21 fixed to the vertical rod 11 of the shoji 7, and the operating rod 14 is slidably disposed between the vertical rod 5 and the surface plate 21.
A trigger 22 as a swing lever is attached to the surface side of the surface plate 21 so as to be rotatable about a swing shaft 23. A rib 23 a is formed on the back side of the swing shaft 23 of the trigger 22.

図３のＢに示すように、作動杵１４には、トリガー２２のリブ２３ａが移動できる長孔通路２５を形成し、下部に第１規制孔２６を形成し、その上にある下通路２５ａを挟んで第２規制孔２７を形成し、さらにその上側には上通路２５ｂを挟んで長孔２８を形成している。通路２５ａ，２５ｂの幅は、ほぼトリガー２２のリブ２３ａ幅と一致させ、リブ２３ａが通過できる程度の幅に形成されている。第１規制孔２６、第２規制孔２７及び長孔２８の幅は、トリガー２２のリブ２３ａが傾斜して、リブ２３ａの両端部が各孔２６〜２８の側縁部に当接する大きさに形成されている。第１規制孔２６及び第２規制孔２７の長さ（作動杵１４の摺動方向）は、多少の遊び（クリアランス）を有するように形成されている。クリアランスが必要なのは、ハンドル１６の角度を丁度、例えば、障子７が内開き状態にあるときは、ほぼ正確にハンドル１６を９０度位置に合わせなければ、トリガー２３がスムースに動かないからである。 As shown in FIG. 3B, the operating rod 14 is formed with a long hole passage 25 through which the rib 23a of the trigger 22 can move, a first restriction hole 26 is formed in the lower portion, and a lower passage 25a on the upper passage 25a is formed. A second restriction hole 27 is formed on the upper side, and a long hole 28 is formed on the upper side with the upper passage 25b interposed therebetween. The widths of the passages 25a and 25b are formed so as to be substantially the same as the width of the rib 23a of the trigger 22 so that the rib 23a can pass through. The widths of the first restriction hole 26, the second restriction hole 27, and the long hole 28 are such that the rib 23 a of the trigger 22 is inclined and both end portions of the rib 23 a are in contact with the side edge portions of the holes 26 to 28. Is formed. The lengths of the first restriction hole 26 and the second restriction hole 27 (sliding direction of the operating rod 14) are formed so as to have some play (clearance). The clearance is necessary because the angle of the handle 16 is exactly the same, for example, when the shoji 7 is in the inwardly open state, the trigger 23 does not move smoothly unless the handle 16 is adjusted to the 90 degree position almost accurately.

トリガー２２は、障子７の開状態で、図示しないスプリングバネで、反時計周りへ回動する方向へバネ力が付加され、図３のＡに示すように、窓枠１の縦枠５がある方向へ、先端側が突出する。そして、トリガー２２は、第１規制孔２６，第２規制孔２７及び長孔２８のいずれかの側縁部に当接して回転が阻止されて、図３のＡに示す位置で静止する。したがって、図示の位置では、トリガー２２は矢印ａに示す方向へ回動が可能となる。
トリガー２２は、障子７が閉じ状態になると、窓枠１の縦枠５に当たり、図４のＡに示す縦框１１が延びる垂直方向に向いて、縦框１１と重なるようにして静止する。 When the shoji 7 is in the open state, the trigger 22 is applied with a spring force in a counterclockwise direction by a spring spring (not shown), and there is a vertical frame 5 of the window frame 1 as shown in FIG. The tip side protrudes in the direction. Then, the trigger 22 comes into contact with a side edge portion of any one of the first restriction hole 26, the second restriction hole 27, and the long hole 28 to be prevented from rotating, and stops at the position shown in FIG. Accordingly, at the illustrated position, the trigger 22 can be rotated in the direction indicated by the arrow a.
When the shoji 7 is in the closed state, the trigger 22 hits the vertical frame 5 of the window frame 1 and stops in a vertical direction in which the vertical rod 11 shown in FIG.

リブ２３ａと、第１規制孔２６，第２規制孔２７及び長孔２８の位置関係を説明すると、
図２のＡに示すように、ハンドル１６を障子７の内倒し位置にすると、作動杵１４が下側に移動し、リブ２３ａが第１規制孔２６に収容される。図２のＢに示すように、ハンドル１６を障子７の内開き位置にすると、作動杵１４が図２のＡの位置よりも上側に摺動し、リブ２３ａが第２規制孔２７に収容される。図２のＣに示すように、ハンドル１６を障子７の閉じ状態位置にすると、作動杵１４がさらに上側に移動し、リブ２３ａが長孔２８に収容される。リブ２３ａが第１規制孔２６に収容された状態では、障子７の内倒しができ、リブ２３ａが第２規制孔２７に収容されて状態では、障子７の内開きができる。リブ２３ａが長孔２８に収容されて状態は、障子７の施錠状態である。 The positional relationship between the rib 23a and the first restriction hole 26, the second restriction hole 27, and the long hole 28 will be described.
As shown in FIG. 2A, when the handle 16 is moved to the inward position of the shoji 7, the operating rod 14 moves downward, and the rib 23 a is accommodated in the first restriction hole 26. As shown in FIG. 2B, when the handle 16 is set to the inward opening position of the shoji 7, the operating rod 14 slides upward from the position A in FIG. 2, and the rib 23 a is accommodated in the second restriction hole 27. The As shown in FIG. 2C, when the handle 16 is moved to the closed position of the shoji 7, the operating rod 14 moves further upward, and the rib 23 a is accommodated in the long hole 28. When the rib 23a is accommodated in the first restriction hole 26, the shoji 7 can be tilted inward, and when the rib 23a is accommodated in the second restriction hole 27, the shoji 7 can be opened inward. The state in which the rib 23 a is accommodated in the long hole 28 is a locked state of the shoji 7.

障子７が内開き状態であるときは、図３のＡに示すように、トリガー２２は傾斜した状態であるので、一体的に形成されたリブ２３ａが、第２規制孔２７で傾斜した状態となり、リブ２３ａ幅とほぼ同幅の通路２５ａ，２５ｂを通ることができず、第２規制孔２７の角部にリブ２３ａの端部が当接して摺動規制される。したがって、障子７の内開き状態では、リブ２３ａによって、作動杵１４の摺動が規制され、ハンドル１６を上方へ回転させようとしても、回転が阻止される。よって、障子７の内開き状態から図１１に示す蝶番Ａから係止ピン１９の係合が解除されるのを防止している。 When the shoji 7 is in the inwardly open state, as shown in FIG. 3A, the trigger 22 is in an inclined state, so that the integrally formed rib 23a is inclined in the second restriction hole 27. The ribs 23a cannot pass through the passages 25a and 25b having the same width as the width of the ribs 23a, and the end portions of the ribs 23a come into contact with the corners of the second restricting holes 27 to be restricted. Therefore, when the shoji 7 is in the open state, the rib 23a restricts the sliding of the operating rod 14, and the rotation is prevented even if the handle 16 is rotated upward. Therefore, the engagement of the locking pin 19 from the hinge A shown in FIG.

同様に、障子７が内倒し状態であるときは、トリガー２２のリブ２３ａが、図２のＡに示すように、第１規制孔２６で傾斜した状態であるので、リブ２３ａが通路２５ａを通ることができず、第１規制孔２６の角部にリブ２３ａの端部が当接して移動規制される。したがって、障子７の内倒し状態では、リブ２３ａによって、作動杵１４の摺動が規制され、ハンドル１６を回転させようとしても、回転が阻止される。よって、障子７の内倒し状態から、図１３に示す支承装置Ｄと係止ピン８９の係合が解除されるのを防止している。 Similarly, when the shoji 7 is in the inward state, the rib 23a of the trigger 22 is inclined at the first restricting hole 26 as shown in FIG. 2A, so that the rib 23a passes through the passage 25a. In this case, the end of the rib 23 a comes into contact with the corner of the first restriction hole 26 and the movement is restricted. Therefore, in the state in which the shoji 7 is turned inward, the sliding movement of the operating rod 14 is restricted by the rib 23a, and the rotation is prevented even if the handle 16 is rotated. Therefore, the engagement between the support device D and the locking pin 89 shown in FIG.

図５は、ハンドル１６の操作位置と操作状態を示す図である。
多方向開放窓は機構上、ハンドル１６を横向き（９０度位置）にした状態の内開き可能範囲ｅを有し、ハンドル１６を上向きにした内倒し可能範囲ｄを有する。そして、第１安全装置Ｊが正常に作動しているときのハンドルロック範囲ｆは、内倒し可能範囲ｄと内開き可能範囲ｅが一部重なっている。
障子７を閉めた状態ではトリガー２２が作動しないので、ハンドル１６を自由に回転させることができる。障子７を閉めたままハンドル１６を内倒しにした状態で、トリガー２２によるハンドルロックがかかることなく、通路２５ａにリブ２３ａが微妙に引っ掛かったまま（図５の領域Ｃの範囲）、障子７を内開き、この状態からハンドル１６を上向きにして障子７を内倒しにすると、蝶番Ａから係止ピン１９が外れて内倒し、内開き状態になって、ヒンジ装置（図１２参照）の一点支持状態になってしまうおそれがある。 FIG. 5 is a diagram illustrating an operation position and an operation state of the handle 16.
The multi-directional opening window has an inwardly openable range e in a state where the handle 16 is turned sideways (90 ° position) and has an inwardly movable range d in which the handle 16 is turned upward. The handle lock range f when the first safety device J is operating normally is such that the inward tiltable range d and the inwardly openable range e partially overlap.
Since the trigger 22 does not operate when the shoji 7 is closed, the handle 16 can be freely rotated. With the handle 16 turned inward with the shoji 7 closed, the handle 23 is not locked by the trigger 22 and the rib 23a is slightly caught in the passage 25a (range C in FIG. 5). When the shoji 7 is tilted inward with the handle 16 facing upward in this state, the locking pin 19 is detached from the hinge A and inwardly tilted to be in the inwardly open state, thereby supporting the hinge device (see FIG. 12) at one point. There is a risk of becoming a state.

そこで、本実施の形態では、第１安全装置Ｊとともに第２安全装置Ｋにトリガー２２（第１安全装置のトリガーと同じ符号を付す）を設け、障子の上框８に取付けている。
図７のＢに示すように、第２安全装置Ｋは、第１安全装置Ｊと同じ形状のトリガー２２を上框７に取付けている。すなわち、障子７の上框８に固定した表面板３１を設け、上框８と表面板３１との間に作動杵１４が摺動可能に配設されている。
表面板３１の表面側には、トリガー２２が揺動軸２３を中心に回動可能に取付けられている。トリガー２２の揺動軸２３の裏側にはリブ２３ａが形成されている。 Therefore, in the present embodiment, the first safety device J and the second safety device K are provided with a trigger 22 (the same reference numeral as that of the first safety device) is attached to the upper arm 8 of the shoji.
As shown to B of FIG. 7, the 2nd safety device K has attached the trigger 22 of the same shape as the 1st safety device J to the upper collar 7. FIG. That is, the surface plate 31 fixed to the upper arm 8 of the shoji 7 is provided, and the operating rod 14 is slidably disposed between the upper arm 8 and the surface plate 31.
A trigger 22 is attached to the surface side of the surface plate 31 so as to be rotatable about a swing shaft 23. A rib 23 a is formed on the back side of the swing shaft 23 of the trigger 22.

図７のＢに示すように、作動杵１４には、トリガー２２のリブ２３ａが移動できる長孔通路３５を形成し、下部に第３規制孔３６を形成し、その上にある下通路３５ａを挟んで第４規制孔３７を形成し、さらにその上側には上通路３５ｂを挟んで長孔３８を形成している。通路３５ａ，３５ｂの幅は、ほぼトリガー２２のリブ２３ａ幅と一致させ、リブ２３ａが通過できる程度の幅に形成されている。第３規制孔３６、第４規制孔３７及び長孔３８の幅は、トリガー２２のリブ２３ａが傾斜して、リブ２３ａの両端部が各孔３６〜３８の側縁部に当接する大きさに形成されている。第３規制孔３６は、第１安全装置Ｊのリブ２３ａが第１規制孔２６に収容された状態で、第２安全装置Ｋのリブ２３ａを収容し、第４規制孔３７は、第１安全装置Ｊのリブ２３ａが第２規制孔２７に収容された状態で、第２安全装置Ｋのリブ２３ａを収容する。 As shown in FIG. 7B, the operating rod 14 is formed with a long hole passage 35 in which the rib 23a of the trigger 22 can move, a third restriction hole 36 is formed in the lower portion, and a lower passage 35a on the lower restriction passage 35a is formed. A fourth restriction hole 37 is formed on the upper side, and a long hole 38 is formed on the upper side with the upper passage 35b interposed therebetween. The widths of the passages 35a and 35b are formed so as to be substantially equal to the width of the rib 23a of the trigger 22 so that the rib 23a can pass therethrough. The widths of the third restriction hole 36, the fourth restriction hole 37, and the long hole 38 are such that the rib 23a of the trigger 22 is inclined and both end portions of the rib 23a are in contact with the side edge portions of the holes 36 to 38. Is formed. The third restriction hole 36 accommodates the rib 23a of the second safety device K in a state where the rib 23a of the first safety device J is accommodated in the first restriction hole 26, and the fourth restriction hole 37 corresponds to the first safety hole 37. The rib 23 a of the second safety device K is accommodated in a state where the rib 23 a of the device J is accommodated in the second restriction hole 27.

図７のＡに示す第１安全装置Ｊと図８のＢに示す安全装置Ｋのクリアランスについて説明すると、第１安全装置Ｊのリブ２３ａの収容部である第１規制孔２６及び第２規制孔２７の大きさは、トリガー２２がスムースに揺動できるように設定する一方、第１規制孔２６及び第２規制孔２７の大きさは遊びを少なくすることが好ましい。ハンドル１６の遊び量を大きくなるのを防止するととともに、内開き内倒し機構の切り替え範囲が狭くなるからである。
そのため、第１安全装置Ｊでは、第１規制孔２６及び第２規制孔２７のクリアランスを最小限にしている。図７のＡに示すように第２規制孔２６を例にあげると、第２規制孔２７のストロークＬ１に対して、図７のＢに示すように、それに対応する第４規制孔３７のストロークＬ２を第１規制孔２６の両端よりも外側へ延ばすようにして広く形成している。 The clearance between the first safety device J shown in FIG. 7A and the safety device K shown in FIG. 8B will be described. The first restriction hole 26 and the second restriction hole, which are the accommodating portions of the ribs 23a of the first safety device J. The size of 27 is set so that the trigger 22 can swing smoothly, while the size of the first restricting hole 26 and the second restricting hole 27 preferably reduces play. This is because the play amount of the handle 16 is prevented from being increased and the switching range of the inwardly opening / falling mechanism is narrowed.
Therefore, in the first safety device J, the clearance between the first restriction hole 26 and the second restriction hole 27 is minimized. Taking the second restriction hole 26 as an example as shown in FIG. 7A, the stroke of the fourth restriction hole 37 corresponding to the stroke L1 of the second restriction hole 27 as shown in FIG. L2 is formed so as to extend outward from both ends of the first restriction hole 26.

これを図８にて説明すると、障子７を閉めた状態では第１及び第２安全装置Ｊ，Ｋの各トリガー２２が作動しないので、ハンドル１６を自由に回転させることができる。障子７を閉めたままハンドル１６を内開きにした状態で、第１安全装置Ｊトリガー２２によるハンドルロックがかかることなく、図７のＡに示すように、通路２５ａにリブ２３ａが微妙に引っ掛かったまま障子７を内開きし、この状態からハンドル１６を上向きにして障子７を内倒しにすると、第１安全装置Ｊのトリガー２２が１つでは、図１１に示す蝶番Ａから係止ピン１９が外れて内倒し、内開き状態になって、ヒンジ装置の一点支持状態になってしまうおそれがある。しかしながら、第２安全装置Ｋにトリガー２２を設け、第４規制孔３７のストロークを大きくしたので、通路２５ａに第１安全装置Ｊのリブ２３ａが微妙に引っ掛かった状態では、第２安全装置Ｋのトリガー２２のリブ２３ａが通路３５ａに引っ掛かることなく、トリガー２２は傾斜状態にある。したがって、ハンドル１６を回転させても図８に示すハンドルロック範囲ｇまでハンドル１６を回転させると、第２安全装置Ｋのリブ２３ａによって作動杵１４の摺動が規制されて、障子７が内開きされた状態であっても、ハンドル１６が回転することなく、内倒し状態になることがない。
なお、図１に示す第１安全装置Ｊの取付箇所は、上框８のほぼ中間部に取付け、第２安全装置Ｋの取付箇所は、縦框１１のほぼ中間部に取付けているが、回転軸からできるだけ離して取付けたほうが好ましい。すなわち、第１安全装置Ｊであれば、内開き状態の障子７の回転軸となる縦枠４から離し（縦枠５側に近づける）、第２安全装置Ｋであれば、内倒し状態の障子７の回転軸となる下枠３から離した位置（上枠２側に近づける）に配置することが好ましい。 This will be described with reference to FIG. 8. Since the triggers 22 of the first and second safety devices J and K do not operate when the shoji 7 is closed, the handle 16 can be freely rotated. As shown in FIG. 7A, the rib 23a was slightly caught in the passage 25a without the handle lock by the first safety device J-trigger 22 with the handle 16 opened inward with the shoji 7 closed. If the shoji 7 is opened inward and the shoji 7 is turned inward from this state with the handle 16 facing upward, if the trigger 22 of the first safety device J is one, the locking pin 19 from the hinge A shown in FIG. There is a risk of falling inward and inwardly opening, and becoming a one-point support state of the hinge device. However, since the trigger 22 is provided in the second safety device K and the stroke of the fourth restriction hole 37 is increased, the rib 23a of the first safety device J is slightly caught in the passage 25a. The trigger 22 is in an inclined state without the rib 23a of the trigger 22 being caught by the passage 35a. Therefore, when the handle 16 is rotated to the handle lock range g shown in FIG. 8 even if the handle 16 is rotated, the sliding of the operating rod 14 is restricted by the rib 23a of the second safety device K, and the shoji 7 is opened inward. Even in this state, the handle 16 does not rotate and does not fall inward.
In addition, the attachment location of the 1st safety device J shown in FIG. 1 is attached to the substantially middle part of the upper cage | basket 8, and the attachment location of the 2nd safety device K is attached to the substantially middle portion of the vertical rod 11, but rotation It is preferable to mount it as far as possible from the shaft. That is, if it is the 1st safety device J, it will move away from the vertical frame 4 used as the rotating shaft of the shoji 7 of the inner opening state (it will approach the vertical frame 5 side), and if it is the 2nd safety device K, it will be the shoji in the state of falling down. 7 is preferably arranged at a position (closer to the upper frame 2 side) away from the lower frame 3 serving as a rotation axis.

これについては、障子の内倒し状態から内開き状態に移行するときも同様に、リブ２３ａが第１規制孔２６から通路２５ａに僅かに入り込んだ状態で、障子７を内倒ししたまま、ハンドル１６を内開き状態に回動しても、ハンドル１６をハンドルロック範囲ｇで回転したときに、第２安全装置Ｋのリブ２３ａが第４規制孔３６に規制されて、内倒し状態から、内開き内開き状態となることを防止できる。
このように、本実施の形態については、安全装置を２個設けることによって、基準となる第１安全装置Ｊの規制孔２６，２７に対して第２安全装置Ｋの規制孔３６，３７のストロークを変更することによって、障子７の内開き内倒し状態及び内倒し内開き状態になるのを防止することができる。 In this regard, when the shoji is turned from the inward state to the inwardly open state, similarly, the handle 16 remains in the state that the shoji 7 is inward with the rib 23a slightly entering the passage 25a from the first restriction hole 26. When the handle 16 is rotated within the handle lock range g, the rib 23a of the second safety device K is restricted by the fourth restricting hole 36, and the inner It is possible to prevent the inward opening state.
As described above, in the present embodiment, by providing two safety devices, the strokes of the restriction holes 36 and 37 of the second safety device K with respect to the restriction holes 26 and 27 of the first safety device J serving as a reference. By changing this, it is possible to prevent the shoji 7 from being inwardly opened inward and inwardly inward.

以上、本発明の実施の形態について説明したが、本発明の技術的思想に基づいて、勿論、本発明は種々の変形又は変更が可能である。
例えば、上記実施の形態では、図２に示すようにハンドル１６を横向きにすると、内開きとなり、ハンドル１６を上向きにすると内倒しになる障子７を例としたが、ハンドルを横向きにすると内倒しとなり、ハンドルを上向きにすると内開きになる内倒し内開き機構を有する障子にも適用が可能である。
例えば、上記実施の形態では、第２安全装置Ｋを上框８に配設したが、第１安全装置Ｊと同様に縦框１１に配設してもよい。
また、本発明は、従来例の図１５に示すタイプの安全装置Ｇについても適用可能であり、上記実施の形態と同様に、障子７が内倒し内開きになるおそれがあり、係止ピン９８に対するクリアランスの異なる複数の安全装置を取付けることで、本願発明と同様の効果がある。 While the embodiments of the present invention have been described above, the present invention can of course be modified or changed in various ways based on the technical idea of the present invention.
For example, in the above embodiment, as shown in FIG. 2, the shoji 7 is an example in which the handle 16 is inwardly opened when the handle 16 is turned sideways and is turned inward when the handle 16 is turned up. Thus, the present invention can also be applied to a shoji having an inwardly-opening inner opening mechanism that opens inward when the handle is turned upward.
For example, in the above-described embodiment, the second safety device K is disposed on the upper cage 8, but may be disposed on the vertical cage 11 like the first safety device J.
Further, the present invention is also applicable to the safety device G of the type shown in FIG. 15 of the conventional example, and there is a possibility that the shoji 7 is turned inward and opened in the same manner as in the above embodiment. By installing a plurality of safety devices with different clearances, there are the same effects as the present invention.
