May be provided. The upper window screen is mainly used for indoor and outdoor ventilation.

このような窓開口部の上側の窓障子としては、窓開口部の少なくとも一方の竪枠に沿って上下動可能に設けた連結桿の上下動に連動して開閉するように構成されている、いわゆる横すべり出し窓が当業者によく知られている。横すべり出し窓については、特許文献１、特許文献２にも開示されており、横すべり出し窓の基本的な構成や窓障子の動きについてはこれらの文献を参照することができる。 As the window shoji on the upper side of such a window opening, it is configured to open and close in conjunction with the vertical movement of a connecting rod provided so as to be movable up and down along at least one frame of the window opening. So-called side sliding windows are well known to those skilled in the art. The lateral sliding window is also disclosed in Patent Document 1 and Patent Document 2, and these documents can be referred to for the basic configuration of the lateral sliding window and the movement of the window shoji.

横すべり出し窓における窓障子の開閉は、操作部のハンドルの回転操作（ハンドルを手で掴んでぐるぐる回すこと）によって、連結桿を少しずつ上動あるいは下動させて窓障子を徐々に開閉させるものであるため、火災時等の非常時に全閉状態にある窓障子を開放させて排煙を行なおうとしても、窓障子を全開状態とするまでには時間を要し、迅速な窓障子の開放、排煙を行なうことができなかった。
特開２００４−２９３０８５ 特開２００７−６３８２４ The opening and closing of the window shoji in the side sliding window is to gradually open and close the window shoji by gradually moving the connecting rod up or down by rotating the handle of the operation unit (by grabbing the handle with your hand). Therefore, even if you try to exhaust smoke by opening a window shoji that is fully closed in the event of an emergency such as a fire, it takes time to fully open the window shoji. Opening and smoke removal could not be performed.

In the connecting member 10 in a vertical posture, the locking recess 101 is formed by upper and lower horizontal sides, a vertical side at the bottom, and an opening facing the indoor side. In the connecting member 10 in the vertical posture, the indoor side portion of the connecting member 10 includes an upper vertical portion 103 positioned above the locking recess 101, an inclined portion 104 below the locking recess 101, and an inclined portion 104. It consists of a lower vertical part 105 located on the lower side.

連結部材１０の下端の回動軸１００にはバネ１０２が設けてあり、連結部材１０を室内側へ回動させるように付勢している。連結部材１０は、基端側の回動付勢によって、上方部位が室外側へ倒れるように回動することを防止している。第２連結桿９の側面には、連結部材１０の下方部位に位置してストッパ１０６が設けてあり、通常時には、連結部材１０が垂直姿勢なった時に、連結部材１０の室内側部位の下側垂直部１０５がストッパ１０６に当接することで（図８（Ａ）、図１０参照）、垂直姿勢が維持されている。この時、連結部材１０の上端垂直部１０３は竪枠２の内壁に近接している。連結部材１０が垂直姿勢にある時に、係止凹部１０１が第１連結桿８の係止突起８４に係止する。係止凹部１０１と係止突起８４が係止状態にある時には、係止突起８４には上下から係止凹部１０１の水平辺が当接ないし近接しており、第１連結桿８と連結部材１０は一体で上下動する。連結部材１０の下端は第２連結桿９に回動のみを許容する態様で連結されており、したがって、係止凹部１０１と係止突起８４が係止状態にある時には、第１連結桿８、連結部材１０、第２連結桿９は一体で上下動する。 The rotating shaft 100 at the lower end of the connecting member 10 is provided with a spring 102, which urges the connecting member 10 to rotate indoors. The connecting member 10 is prevented from rotating so that the upper part falls to the outdoor side by the rotation bias on the base end side. A stopper 106 is provided on a side surface of the second connecting rod 9 at a lower portion of the connecting member 10. Normally, when the connecting member 10 is in a vertical posture, a lower side of the indoor side portion of the connecting member 10. The vertical posture is maintained by the vertical portion 105 coming into contact with the stopper 106 (see FIGS. 8A and 10). At this time, the upper end vertical portion 103 of the connecting member 10 is close to the inner wall of the frame 2. When the connecting member 10 is in the vertical posture, the locking recess 101 is locked to the locking protrusion 84 of the first connecting rod 8. When the locking recess 101 and the locking projection 84 are in the locked state, the horizontal side of the locking recess 101 is in contact with or close to the locking projection 84 from above and below. Move up and down as a unit. The lower end of the connecting member 10 is connected to the second connecting rod 9 in such a manner as to allow only the rotation. Therefore, when the locking recess 101 and the locking projection 84 are in the locked state, the first connecting rod 8, The connecting member 10 and the second connecting rod 9 move up and down together.

第２連結桿９は、第２障子７に沿って下枠４に近接するまで延出している。第２連結桿９の下方部位には、第２連結桿９を上下動させる作動機構が設けてある。作動機構は、竪枠２の室内側に設けられた操作部Ｓとしてのハンドル９０と、ハンドル９０の回転操作に連動して上下動するオペレータアーム９１と、一端が第２連結桿に回動自在に連結され、他端がオペレータアーム９１に回動自在に連結されている連結板９２と、からなり、オペレータアーム９１の上下回動に連動して連結板９２を介して第２連結桿９が上下動するようになっている。通常時には、係止凹部１０１と係止突起８４が係止状態にあり、操作部Ｓの操作によって、第１連結桿８、連結部材１０、第２連結桿９は一体で上下動する。 The second connecting rod 9 extends along the second shoji 7 until it approaches the lower frame 4. An operating mechanism for moving the second connecting rod 9 up and down is provided below the second connecting rod 9. The operating mechanism includes a handle 90 as an operation unit S provided on the indoor side of the rod frame 2, an operator arm 91 that moves up and down in conjunction with a rotation operation of the handle 90, and one end freely rotatable to the second connecting rod. , And the other end of the second connecting rod 9 is connected to the operator arm 91 via the connecting plate 92 in conjunction with the up-and-down rotation of the operator arm 91. It is designed to move up and down. Normally, the locking recess 101 and the locking projection 84 are in a locked state, and the first connecting rod 8, the connecting member 10, and the second connecting rod 9 are moved up and down integrally by the operation of the operation portion S.

第１障子６の通常時の開閉動作について説明する。図５は横すべり出し窓の全閉状態を示し、第１障子６が閉鎖姿勢にあり、第１連結桿８、第２連結桿９、連結部材１０は、全閉姿勢である第１の高さ位置にある。この状態から、ハンドル９０を第１の方向（「開」方向）に回転させると、オペレータアーム９１が下方に回動して連結板９２を下方に移動させ、連結板９２が下方に移動することで、連結板９２に連結されている第２連結桿９が下方に移動し、連結部材１０を介して第２連結桿９と一体となっている第１連結桿８が、リンク８１と回動アーム８２を屈曲させながら下方に移動して、全開姿勢である第２の高さ位置となる。回動アーム８２が下方に回動することで、回動軸８３の回転が他方の第１連結桿８´の回動アーム及びリンクに伝達され、他方の第１連結桿８´も同時に下動する。 The normal opening / closing operation of the first shoji 6 will be described. FIG. 5 shows the side sliding window fully closed, the first shoji 6 is in the closed position, and the first connecting rod 8, the second connecting rod 9, and the connecting member 10 are in the fully closed position. In position. From this state, when the handle 90 is rotated in the first direction (the “open” direction), the operator arm 91 rotates downward to move the connecting plate 92 downward, and the connecting plate 92 moves downward. Thus, the second connecting rod 9 connected to the connecting plate 92 moves downward, and the first connecting rod 8 integrated with the second connecting rod 9 via the connecting member 10 rotates with the link 81. The arm 82 is moved downward while being bent to reach the second height position in the fully open position. By rotating the rotating arm 82 downward, the rotation of the rotating shaft 83 is transmitted to the rotating arm and the link of the other first connecting rod 8 ′, and the other first connecting rod 8 ′ is also moved downward simultaneously. To do.

第１連結桿８、８´が下方に移動すると、第１障子６の回動支軸６１がガイド溝６２に案内されて下方にスライドしながら、アーム６０の上端が室外側に回動し、第１障子６は、垂直姿勢の全閉位置から上端側が降下しながら下端側が室外側にすべり出すように回動して、図６に示すような傾斜姿勢の全開位置となる。この時、第１連結桿８、第２連結桿９、連結部材１０は、全開姿勢である第２の高さ位置にある。ハンドル９０の回転操作によって、第１障子６を、０〜４５度の任意の角度で停止させることができる。本実施態様では、第１障子６が４５度の角度で室外側に回動した時が全開状態となる。図６の状態から、ハンドル９０を「閉」方向に回転させれば、第１連結桿８、第２連結桿９、連結部材１０は、一体で上動して、全閉姿勢である第１の高さ位置まで移動し、図５に示す全閉状態となる。 When the first connecting rods 8 and 8 ′ move downward, the upper support 61 of the first shoji 6 is guided by the guide groove 62 and slides downward, while the upper end of the arm 60 rotates outward. The first shoji 6 is rotated so that the lower end slides out to the outdoor side while the upper end descends from the fully closed position in the vertical posture, and becomes the fully open position in the inclined posture as shown in FIG. At this time, the 1st connection rod 8, the 2nd connection rod 9, and the connection member 10 exist in the 2nd height position which is a fully open attitude | position. The first shoji 6 can be stopped at an arbitrary angle of 0 to 45 degrees by rotating the handle 90. In this embodiment, the first shoji 6 is fully opened when it is turned to the outdoor side at an angle of 45 degrees. If the handle 90 is rotated in the “closed” direction from the state of FIG. 6, the first connecting rod 8, the second connecting rod 9, and the connecting member 10 move up together to be in the fully closed position. To the full height position shown in FIG.

次に、第１障子６の非常時の開放について図７、図８に基づいて説明する。第１連結桿８の下端側と第２連結桿９の上端側との間には、第１連結桿８を、第２連結桿９に対して当該第１連結桿８を接近させる方向（第１連結桿８を下動させる方向、すなわち、閉鎖姿勢にある第１障子６を開放させる方向）に付勢する付勢手段としての圧縮バネ１１が設けてある。圧縮バネ１１の上端は第１連結桿８の下方部位に連結されており、圧縮バネ１１の下端は第２連結桿９の上方部位に連結されており、係止凹部１０１と係止突起８４が係止状態にある時には、連結部材１０によって第１連結桿８の下端と第２連結桿９の上端とは距離Ｄ１だけ離間しており、圧縮バネ１１は伸長状態にある。伸長状態にある圧縮バネ１１によって第１連結桿８には、第１連結桿８を下方に移動させるような力が作用しているが、第１連結桿８の係止突起８４が係止凹部１０１の下側の水平辺に当接することで、連結部材１０が突っ張って第１連結桿８の下方への移動が規制されている。 Next, the emergency opening of the first shoji 6 will be described with reference to FIGS. Between the lower end side of the first connecting rod 8 and the upper end side of the second connecting rod 9, the first connecting rod 8 is made to approach the second connecting rod 9 in the direction (first A compression spring 11 is provided as an urging means for urging in the direction in which the one connecting rod 8 is moved downward, that is, the direction in which the first shoji 6 in the closed posture is opened. The upper end of the compression spring 11 is connected to the lower part of the first connecting rod 8, the lower end of the compression spring 11 is connected to the upper part of the second connecting rod 9, and the locking recess 101 and the locking projection 84 are provided. When in the locked state, the lower end of the first connecting rod 8 and the upper end of the second connecting rod 9 are separated by the distance D1 by the connecting member 10, and the compression spring 11 is in the extended state. A force that moves the first connecting rod 8 downward is exerted on the first connecting rod 8 by the compression spring 11 in the extended state, but the locking projection 84 of the first connecting rod 8 is the locking recess. By abutting on the lower horizontal side of 101, the connecting member 10 is stretched and the downward movement of the first connecting rod 8 is restricted.

連結部材１０は、下端のバネ１０２によって、室内側へ回動するように付勢しており、連結部材１０の上方部位が室外側へ回動することを防止している。通常時には、連結部材１０の下側垂直部１０５がストッパ１０６に当接することで垂直姿勢が維持されている。 The connecting member 10 is biased so as to be rotated indoors by a spring 102 at the lower end, and the upper portion of the connecting member 10 is prevented from rotating outward. At normal times, the vertical posture is maintained by the lower vertical portion 105 of the connecting member 10 coming into contact with the stopper 106.

竪枠２には、第１障子６が通常の全閉状態にある時に、垂直姿勢で係止状態にある連結部材１０の上方部位（上記竪枠２の内壁に近接している室内側部位の上側垂直部１０３）の高さに対応する位置に解除ピン１３が出没可能に設けてある。竪枠２の室内側には、解除ピン１３を出没させるための非常時開放スイッチ１２が設けてある。解除ピン１３は、非常時開放スイッチ１２の操作によって、竪枠２の内壁から室外側へ突出した姿勢と、非常時開放スイッチ１２のボックス１２０内に退避した姿勢との間で移動可能となっている。スイッチの操作によってある部材を出没させる機構は当業者に周知であるので、詳細な説明は省略する。 When the first shoji 6 is in a normal fully closed state, the upper frame 2 of the connecting member 10 that is locked in the vertical posture (the indoor side part close to the inner wall of the upper frame 2 is attached to the vertical frame 2. A release pin 13 is provided at a position corresponding to the height of the upper vertical portion 103) so as to be able to appear and retract. An emergency release switch 12 for causing the release pin 13 to appear and disappear is provided on the indoor side of the frame 2. The release pin 13 can be moved between a posture protruding from the inner wall of the saddle frame 2 to the outdoor side and a posture retracted in the box 120 of the emergency release switch 12 by the operation of the emergency release switch 12. Yes. Since a mechanism for moving a member in and out by operating a switch is well known to those skilled in the art, a detailed description thereof will be omitted.

図８（Ａ）は、第１障子６が全閉状態にある場合を示しており、第１連結桿、連結部材、第２連結桿は、第１の高さ位置にある。垂直姿勢にある連結部材１０の上方部位の係止凹部１０１に第１連結桿８の係止突起８４が室内側から室外側に向かって係止しており、第１連結桿８の下方部位は連結部材１０の上方部位と連結された状態にあり、第１連結桿８の下端と第２連結桿９の上端とが連結部材１０によって距離Ｄ１だけ離間しており、圧縮スプリング１１は伸長姿勢にある。連結部材１０の上方部位の室内側部位（上側垂直部１０３）は竪枠２の室内側面部の内壁に近接しており、解除ピン１３は室内側（ボックス１２０内）に退避した状態にある。ハンドル９０は「閉」方向に回し切った状態にある。 FIG. 8A shows a case where the first shoji 6 is in a fully closed state, and the first connecting rod, the connecting member, and the second connecting rod are in the first height position. The locking projection 84 of the first connecting rod 8 is locked from the indoor side toward the outdoor side in the locking recess 101 at the upper portion of the connecting member 10 in the vertical posture, and the lower portion of the first connecting rod 8 is The lower end of the first connecting rod 8 and the upper end of the second connecting rod 9 are separated from each other by a distance D1 by the connecting member 10, and the compression spring 11 is in the extended posture. is there. The indoor side portion (upper vertical portion 103) of the upper portion of the connecting member 10 is close to the inner wall of the indoor side surface portion of the frame 2 and the release pin 13 is retracted to the indoor side (inside the box 120). The handle 90 is fully turned in the “closed” direction.

図８（Ａ）の状態から、非常時開放スイッチ１２を下方に移動させると（図８（Ｂ））、ボックス１２０内の解除ピン１３が室外側へ突出する。室外側へ突出した解除ピン１３は、連結部材１０の上端側の室内側部位（垂直部１０３）に当接し、連結部材１０の上端側を基端側のバネ１０２の付勢力に抗して室外側へ押圧することで、連結部材１０は下端側を回動支点として上端側が室外側へ倒れるように回動し、連結部材１０の係止凹部１０１が第１連結桿８の係止突起８４から外れて係止状態が解除される（図８（Ｃ））。 When the emergency release switch 12 is moved downward from the state of FIG. 8A (FIG. 8B), the release pin 13 in the box 120 protrudes to the outdoor side. The release pin 13 protruding to the outdoor side contacts the indoor side portion (vertical portion 103) on the upper end side of the connecting member 10, and the upper end side of the connecting member 10 resists the biasing force of the spring 102 on the base end side. By pressing outward, the connecting member 10 rotates so that the upper end side falls to the outdoor side with the lower end side as a rotation fulcrum, and the engaging recess 101 of the connecting member 10 is moved from the engaging protrusion 84 of the first connecting rod 8. It is released and the locked state is released (FIG. 8C).

係止状態が解除されると、第１連結桿８の下動の移動規制が解除され、伸長状態にある圧縮スプリング１１が縮むことで、第２連結桿９の高さ位置（第１の高さ位置）は固定されているので（第２連結桿９の下方部位は、連結板９２、オペレータアーム９１、ハンドル９０に伝動連結されており、ハンドル９０を回転させないと移動しない）、第１連結桿８の下方部位が、圧縮スプリング１１の縮む力に引っ張られて、第１連結桿８が下方へ第２の高さ位置まで移動する（図８（Ｄ））。連結部材１０の上方部位と第１連結桿８の下方部位との連結が解除され、圧縮スプリング１１が縮むことで、第１連結桿８の下端と第２連結桿９の上端とは接近（距離Ｄ２）した状態となる。この時、ハンドル９０は「閉」方向に回し切った状態のままである。 When the locked state is released, the movement restriction of the downward movement of the first connecting rod 8 is released, and the compression spring 11 in the extended state contracts, so that the height position of the second connecting rod 9 (the first height) Is fixed (the lower part of the second connecting rod 9 is connected to the connecting plate 92, the operator arm 91, and the handle 90, and does not move unless the handle 90 is rotated). The lower portion of the flange 8 is pulled by the contracting force of the compression spring 11, and the first connecting rod 8 moves downward to the second height position (FIG. 8D). The connection between the upper part of the connecting member 10 and the lower part of the first connecting rod 8 is released, and the compression spring 11 is contracted, so that the lower end of the first connecting rod 8 and the upper end of the second connecting rod 9 approach (distance). D2). At this time, the handle 90 remains in the fully closed direction.

圧縮スプリング１１の縮小による第１連結桿８の下方への移動量（Ｄ１−Ｄ２）は、第１障子６を全閉状態から全開状態まで回動（４５度）するように設定されており、非常時開放スイッチ１２を下方に移動させるというワンタッチ操作で、第１障子６を迅速に全開状態として、排煙開口を確保することができる。非常時の開放時の第１連結桿８の移動量は、予め、連結部材１０の長さ、連結部材１０によって設定された第１連結桿８の下端と第２連結桿９の上端との離間距離、伸長状態からの圧縮スプリング１１の圧縮量等を調整することで、設定することができる。通常時に、全閉姿勢にある窓障子６が全開姿勢となるまでにハンドル９０の回転操作によって第１連結桿８が下方に移動する移動量と、非常時に、閉鎖姿勢にある窓障子６が全開姿勢となるまでに圧縮スプリング１１の縮小によって第１連結桿８が下方に移動する移動量と、は同じである。図６と図７を見比べると、いずれの全閉状態においても、第１連結桿８の下端の高さ位置が同じであることがわかる。 The downward movement amount (D1-D2) of the first connecting rod 8 due to the reduction of the compression spring 11 is set so as to rotate the first shoji 6 from the fully closed state to the fully open state (45 degrees). With the one-touch operation of moving the emergency release switch 12 downward, the first shoji 6 can be quickly fully opened, and the smoke exhaust opening can be secured. The amount of movement of the first connecting rod 8 at the time of opening in emergency is the distance between the length of the connecting member 10 and the lower end of the first connecting rod 8 set by the connecting member 10 and the upper end of the second connecting rod 9 in advance. The distance can be set by adjusting the compression amount of the compression spring 11 from the extended state. When the window shoji 6 in the fully closed position is normally in the fully open position, the first connecting rod 8 is moved downward by rotating the handle 90. In an emergency, the window shoji 6 in the closed position is fully opened. The amount of movement by which the first connecting rod 8 moves downward by the reduction of the compression spring 11 until the posture is reached is the same. Comparing FIG. 6 and FIG. 7, it can be seen that the height position of the lower end of the first connecting rod 8 is the same in any fully closed state.

図７、図８（Ｄ）に示す非常時全開状態からの連結部材１０の復帰について説明する。図７、図８（Ｄ）に示す非常時全開状態において、第２連結桿９は図５に示す全閉状態における第２連結桿９の高さと同じ位置（第１の高さ位置）にある。ハンドル９０は「閉」方向に回し切った状態にある。第１連結桿８は第２の高さ位置にあり、第１連結桿８は、その機構上、それより下方に移動することはない。 The return of the connecting member 10 from the emergency fully opened state shown in FIGS. 7 and 8D will be described. In the emergency fully opened state shown in FIGS. 7 and 8D, the second connecting rod 9 is at the same position (first height position) as the second connecting rod 9 in the fully closed state shown in FIG. . The handle 90 is fully turned in the “closed” direction. The first connecting rod 8 is in the second height position, and the first connecting rod 8 does not move downward due to its mechanism.

図８（Ｄ）の状態から、非常時開放スイッチ１２を上方に移動させると、突出姿勢にある解除ピン１３が室内側（ボックス１２０内）へ退避する（図９（Ａ）、（Ｂ））。非常時開放スイッチ１２、解除ピン１３は、ボックス１２０内にバネ等を内蔵することによって、非常時開放後に元の位置に自動復帰するように構成してもよい。第１連結桿８の係止突起８４は、連結部材１０の室内側部位（傾斜部１０４）の高さ方向中途部位に当接している。 When the emergency release switch 12 is moved upward from the state of FIG. 8D, the release pin 13 in the protruding posture is retracted indoors (inside the box 120) (FIGS. 9A and 9B). . The emergency release switch 12 and the release pin 13 may be configured to automatically return to their original positions after the emergency release by incorporating a spring or the like in the box 120. The locking protrusion 84 of the first connecting rod 8 is in contact with a midway portion in the height direction of the indoor side portion (inclined portion 104) of the connecting member 10.

この状態からハンドル９０を第１の方向（「開」方向）に回転させて第２連結桿９を下方に移動させる。第２連結桿９が下方に移動すると、圧縮スプリング１１が伸長されていき、係止状態が解除されて上端が自由となっている連結部材１０も下方に移動する。第２の高さ位置にある第１連結桿８に対して第２連結桿９のみが下方に移動することで、第１連結桿８の下端と第２連結桿９の上端との距離は、距離Ｄ２→Ｄ２´→Ｄ１と徐々に大きくなっていく（図９（Ａ）（Ｂ）（Ｃ））。 From this state, the handle 90 is rotated in the first direction (“open” direction) to move the second connecting rod 9 downward. When the second connecting rod 9 moves downward, the compression spring 11 is extended, and the connecting member 10 whose upper end is freed by releasing the locked state also moves downward. The distance between the lower end of the first connecting rod 8 and the upper end of the second connecting rod 9 is such that only the second connecting rod 9 moves downward relative to the first connecting rod 8 at the second height position. The distance D2 → D2 ′ → D1 gradually increases (FIGS. 9A, 9B, and 9C).

連結部材１０は下端の回動基端部に設けたバネ１０２によって室内側に回動するように付勢されており、連結部材１０の室内側部位（傾斜部１０４）は第１連結桿８の係止突起８４に当接しており、連結部材１０は室内側部位（傾斜部１０４）が係止突起８４に摺接・案内されながら下方に移動する（図９（Ｂ））。 The connecting member 10 is biased so as to rotate indoors by a spring 102 provided at the rotating base end portion at the lower end, and the indoor side portion (inclined portion 104) of the connecting member 10 is provided on the first connecting rod 8. The connection member 10 moves downward while being in sliding contact with and guided by the locking protrusions 84 (FIG. 9B).

第２連結桿９が通常の全開状態の位置（第２の高さ位置）まで下動すると、第１連結桿８の下端と第２連結桿９の上端との距離はＤ１となり、連結部材１０の室内側部位（傾斜部１０４）の上方に形成されている係止凹部１０１が第１連結桿８の係止突起８４に係止して垂直姿勢となって、図５、図９（Ｃ）に示す通常の全開状態となる。すなわち、第１連結桿８、第２連結桿９、連結部材１０は、一体で全開姿勢である第２の高さ位置にある。 When the second connecting rod 9 is moved down to the normal fully open position (second height position), the distance between the lower end of the first connecting rod 8 and the upper end of the second connecting rod 9 becomes D1, and the connecting member 10 The locking concave portion 101 formed above the indoor side portion (inclined portion 104) of the first locking rod 8 is locked to the locking projection 84 of the first connecting rod 8 to take a vertical posture, and FIG. 5 and FIG. It becomes a normal full open state shown in. That is, the 1st connection rod 8, the 2nd connection rod 9, and the connection member 10 are in the 2nd height position which is the open position integrally.

この状態から、ハンドル９０を第２の方向（「閉」方向）に回転させて、第１連結桿８、連結部材１０、第２連結桿９を一体で第１の高さ位置まで上動させて、全開状態にある窓障子６を全閉状態とする（図９（Ｄ））。 From this state, the handle 90 is rotated in the second direction (the “closing” direction), and the first connecting rod 8, the connecting member 10, and the second connecting rod 9 are integrally moved up to the first height position. Then, the window shoji 6 in the fully open state is brought into a fully closed state (FIG. 9D).

上記の実施形態では、窓障子が全閉状態にある時（すなわち、第１連結桿８が第１の高さ位置にある時であり、ハンドル９０が「閉」方向に回し切った状態にある時でもある）に、非常時開放手段によって連結部材１０の上方部位と第１連結桿８の下方部位との連結を解除するものについて説明した。本発明に係る窓障子の開放機構を用いた非常時開放は、窓障子が全閉状態にある場合にのみ作動するものではなく、窓障子が開放途中にある場合にも作動するようにしてもよい。これについて図１０に基づいて説明する。図１０において、他の図面との間で共通する構成要素については同一の参照番号が付してあり、他の図面での記載を援用することができる。図１０は、第１連結桿８、連結部材１０´、第２連結桿９が第１の高さ位置と第２の高さ位置との中間の高さに位置する場合を示している。この高さ位置では、窓障子（図示せず）は半開きの状態となる。図１０から明らかなように、連結部材１０´の上方部位は、連結部材１０の上方部位に比べて上方に延出している。連結部材１０´の室内側部位の上方の垂直部１０３´は、解除ピン１３の高さ位置まで延びている。したがって、図１０の状態で、非常時開放スイッチ１２を下方に下げて解除ピン１３を突出させることで、解除ピン１３が連結部材１０´の垂直部１０３´を押し出して、連結部材１０´の係止凹部１０１が第１連結桿８の係止突起から外れて、圧縮スプリング１１に引っ張られて第１連結桿８が下方に移動して第２の高さ位置となり、窓障子が全開状態となる。 In the above embodiment, when the window screen is in the fully closed state (that is, when the first connecting rod 8 is at the first height position, the handle 90 is fully turned in the “closed” direction). In some cases, the connection between the upper part of the connecting member 10 and the lower part of the first connecting rod 8 is released by the emergency opening means. The emergency opening using the window shoji opening mechanism according to the present invention does not operate only when the window shoji is in the fully closed state, and may operate even when the window shoji is in the middle of opening. Good. This will be described with reference to FIG. In FIG. 10, the same reference numerals are given to components common to other drawings, and descriptions in other drawings can be used. FIG. 10 shows a case where the first connecting rod 8, the connecting member 10 ′, and the second connecting rod 9 are located at an intermediate height between the first height position and the second height position. At this height position, the window shoji (not shown) is in a half-open state. As is clear from FIG. 10, the upper part of the connecting member 10 ′ extends upward as compared with the upper part of the connecting member 10. The vertical portion 103 ′ above the indoor portion of the connecting member 10 ′ extends to the height position of the release pin 13. Accordingly, in the state shown in FIG. 10, the emergency release switch 12 is lowered to cause the release pin 13 to protrude, so that the release pin 13 pushes out the vertical portion 103 ′ of the connection member 10 ′, and the engagement of the connection member 10 ′. The locking recess 101 is disengaged from the locking projection of the first connecting rod 8, and is pulled by the compression spring 11, so that the first connecting rod 8 moves downward to the second height position, and the window screen is fully opened. .

本発明は、窓開口部の少なくとも一方の竪枠に沿って上下動可能に設けた連結桿の上下動に連動して開閉するように構成されている窓障子の開放機構として利用することができる。 INDUSTRIAL APPLICABILITY The present invention can be used as a window shoji opening mechanism that is configured to open and close in conjunction with the vertical movement of a connecting rod provided so as to be movable up and down along at least one frame of the window opening. .
