Description

本発明は、窓枠と該窓枠内に内倒し可能に納められる障子との間に気密材を設けた断熱内倒し窓に用いるステーに係わり、更に詳しくは、小角度傾倒位置から、さらに大角度傾倒位置まで障子を傾倒可能としてなるステーに関するものである。 The present invention relates to a stay for use in a heat-insulated inward window in which an airtight material is provided between a window frame and a shoji that is housed inside the window frame, and more specifically, from a small-angle tilt position to a larger size. The present invention relates to a stay that can tilt the shoji to the tilted position.

窓枠内に納められ、防犯上問題のない小角度傾倒位置まで内倒し可能な障子を、該障子の屋外面を屋内側から掃除可能なように、さらに大角度傾倒位置まで内倒し可能としてなる従来の内倒し窓用ステーとして、窓枠の縦枠の中間部に、先端部にピンを有するアームの基端部を枢着し、該アームの先端部のピンを、障子の側枠に上下に延びるように取り付けた長スライドガイドの長溝に、障子の閉鎖時にピンが長溝の上端位置を占める状態で、滑動自在に嵌着し、かつ該長スライドガイドの長溝の上端部に近接する障子の側枠の屋内側の部分に、長溝の上端部に隣接して長溝外を上下方向に延びる状態を揺動上限とし、長溝の上端部を横切って水平方向に延びる状態を揺動下限として上下に揺動可能なピンストップレバーを枢着してなり、該ピンストップレバーを屋内側から操作つまみ（サムターン）で操作することにより、障子を大角度傾倒位置まで傾倒させるものがある（例えば、特許文献１参照。）。 A shoji that is housed in a window frame and can be tilted to a small-angle tilt position that does not have a security problem can be tilted further to a large-angle tilt position so that the outdoor surface of the shoji can be cleaned from the indoor side. As a conventional inward window stay, the base end of an arm having a pin at the tip is pivotally attached to the middle part of the vertical frame of the window frame, and the pin at the tip of the arm is vertically moved to the side frame of the shoji. The sliding guide is slidably fitted into the long groove of the long slide guide attached so as to extend in the state that the pin occupies the upper end position of the long groove when the shoji is closed, and the shoji close to the upper end of the long slide of the long slide guide The upper part of the side frame adjacent to the upper end of the long groove extends vertically above the long groove as the upper limit of swing, and the state extending horizontally across the upper end of the long groove is set as the lower limit of swing. A pivotable pin stop lever is pivotally attached. By operating the-stop lever operation knob from the indoor side (thumb), there is tilting the sash to large angular inclination position (e.g., see Patent Document 1.).

また、障子の縦框に沿って上下摺動自在な摺動子と、この摺動子と窓枠の縦枠に亘って屋内外側方向に回動自在に連結したアームと、前記障子の縦框に取り付けられた摺動子が当接することで障子の倒れ角度を規制する固定ストッパと、前記障子の縦框屋内側面に取付けられた可動ストッパ装置を備え、この可動ストッパ装置は、上下方向に移動操作される操作部材と、この操作部材の上下方向の移動と連動して前記摺動子が当接するストップ位置と摺動子と離隔した非ストップ位置に亘って揺動する可動ストッパを備え、該可動ストッパを屋内側から操作つまみ（上下方向に移動するもの）で操作することにより、障子を大角度傾倒位置まで傾倒させるものがある（例えば、特許文献２参照。）。 Further, a slider that is slidable vertically along the vertical shaft of the shoji, an arm that is pivotally connected to the slider and the vertical frame of the window frame in the indoor outside direction, and the vertical shaft of the shoji A fixed stopper that regulates the tilt angle of the shoji by the contact of the slider attached to the slider, and a movable stopper device that is attached to the vertical inner side of the shoji. The movable stopper device moves in the vertical direction. An operation member to be operated, and a movable stopper that swings between a stop position where the slider abuts and a non-stop position separated from the slider in conjunction with the vertical movement of the operation member, There is one that tilts the shoji to a large angle tilt position by operating the movable stopper from the indoor side with an operation knob (moving vertically) (for example, see Patent Document 2).

さらに、第１の端部が窓枠の縦枠に対して回動自在にかつ上下摺動自在に連結された第１アームと、第１の端部が障子の縦框に対して回動自在に連結されるとともに第２の端部が第１アームの第２の端部に回動自在に連結された第２アームと、第２アームの縦框に対する障子の傾倒方向と同方向への回動を阻止する回動阻止手段と、第２アームの縦框に対する障子の傾倒方向と反対方向への回動を許容する解除位置及びこの回動を阻止する固定位置との間で移動自在となされた可動ストッパとを備え、可動ストッパを屋内側から操作つまみ（上下方向に移動するもの）で操作することにより、障子を大角度傾倒位置まで傾倒させるものがある（例えば、特許文献３参照。）。 Further, a first arm whose first end portion is connected to the vertical frame of the window frame so as to be rotatable and slidable in the vertical direction, and the first end portion is freely rotatable relative to the vertical saddle of the shoji. And a second arm whose second end is pivotally connected to the second end of the first arm, and a rotation in the same direction as the shovel tilting direction with respect to the vertical arm of the second arm. It is movable between a rotation blocking means for blocking the movement, a release position that allows the second arm to rotate in a direction opposite to the tilting direction of the shoji with respect to the vertical arm, and a fixed position that prevents this rotation. And a movable stopper is operated from the indoor side with an operation knob (moving up and down) to tilt the shoji to a large angle tilt position (see, for example, Patent Document 3). .

以上のような従来の内倒し窓用ステーの構成は、いずれも障子の縦框に設けたストッパを屋内側から操作つまみにて操作する構成であるが、窓枠と障子との間に気密材を設けた断熱内倒し窓に適用しようとすると、気密性を確保しながら前記操作つまみを屋内側に設けることが困難であるという問題点があった。例えば、特許文献１及び２の構成では、障子の縦枠の屋内側面に開口部を設ける必要があるため、気密性の確保が困難となる。また、特許文献３の構成では、可動ストッパの屋内側面側に突設した操作つまみ（操作用突起）を操作するため、気密性の確保が困難となる。 The conventional inward window stay configuration as described above is a configuration in which the stopper provided on the shovel of the shoji is operated from the indoor side with the operation knob, but the airtight material is provided between the window frame and the shoji. When it is going to be applied to a heat-insulating inward window provided with the above, there is a problem that it is difficult to provide the operation knob on the indoor side while ensuring airtightness. For example, in the configurations of Patent Documents 1 and 2, since it is necessary to provide an opening on the indoor side surface of the vertical frame of the shoji, it is difficult to ensure airtightness. Further, in the configuration of Patent Document 3, it is difficult to ensure airtightness because an operation knob (operation protrusion) provided on the indoor side surface side of the movable stopper is operated.

本発明は、前記のような問題点を解決するためになされたものであり、気密性の確保が容易な断熱内倒し窓用ステーを得ることを目的とする。また、簡素な構成により前記気密性を確保することができると共に、小角度傾倒位置又は大角度傾倒位置とする動作の信頼性が高い断熱内倒し窓用ステーを得ることを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a thermally insulated inward-turning window stay that can easily ensure airtightness. It is another object of the present invention to provide an insulated inward window stay that can secure the airtightness with a simple configuration and has high reliability in operation at a small angle tilt position or a large angle tilt position.

本発明に係る断熱内倒し窓用ステーは、窓枠の上下左右の枠体及び障子の上下左右の框体の各々に、該枠体及び框体同士の対向面が形成され、該対向面の少なくとも一方に、該対向面間の隙間を塞ぐ気密材が設けられた断熱内倒し窓に用いられるステーであって、第１アームの一端と第２アームの一端とを水平軸まわりに回動可能に連結し、該第１アームの他端を前記窓枠の縦枠に対して水平軸まわりに回動可能にかつ上下方向にスライド可能に取り付け、該第２アームの他端を前記障子の縦框に対して水平軸まわりに回動可能に取り付け、該第２アームの一端に、他端と逆方向の突出部を設け、該突出部の屋外側面に当接して前記第２アームが前記縦框に対して屋外方向へ回動するのを規制する外方回動規制手段が設けられ、前記縦框に対して上下方向にスライド可能に支持されると共に操作片が設けられた可動ストッパを備え、該操作片により該可動ストッパを上方へスライドさせると、前記第２アームが前記縦框に対して屋外方向へ回動可能となるものであり、前記障子を閉じた状態で、前記操作片が前記気密材を弾性変形させて前記縦枠体及び縦框体の対向面間の隙間を通過可能なように、前記操作片を薄板状として左右方向の外方へ延出させ、さらに屋内方向へ屈曲させてなり、該操作片により前記可動ストッパを前記障子の屋内側から操作可能となしたものである。 In the heat-insulating inward window stay according to the present invention, opposed surfaces of the frame and the housing are formed on each of the upper and lower and left and right frames of the window frame and the upper and lower and left and right frames of the shoji, At least one of the stays used in the heat-insulating inward window provided with an airtight material that closes the gap between the opposing surfaces, and the one end of the first arm and the one end of the second arm can be rotated around a horizontal axis. And the other end of the first arm is attached to the vertical frame of the window frame so as to be rotatable about a horizontal axis and slidable in the vertical direction. Mounted so as to be rotatable about a horizontal axis with respect to the eaves, a projecting portion in the opposite direction to the other end is provided at one end of the second arm, and the second arm is in contact with the outdoor side surface of the projecting portion and the vertical arm An outward rotation restricting means for restricting rotation in the outdoor direction with respect to the kite is provided, And a movable stopper provided with an operation piece and slidably supported by the operation piece. When the movable stopper is slid upward by the operation piece, the second arm moves outward with respect to the downside. In a state where the shoji is closed, the operation piece elastically deforms the airtight member so that it can pass through the gap between the opposing surfaces of the vertical frame body and the vertical rod body. The operation piece is formed as a thin plate, extends outward in the left-right direction, and further bent in the indoor direction, so that the movable stopper can be operated from the indoor side of the shoji.

本発明に係る断熱内倒し窓用ステーによれば、窓枠の上下左右の枠体及び障子の上下左右の框体の各々に、該枠体及び框体同士の対向面が形成され、該対向面の少なくとも一方に、該対向面間の隙間を塞ぐ気密材が設けられた断熱内倒し窓に用いられるステーであって、第１アームの一端と第２アームの一端とを水平軸まわりに回動可能に連結し、該第１アームの他端を前記窓枠の縦枠に対して水平軸まわりに回動可能にかつ上下方向にスライド可能に取り付け、該第２アームの他端を前記障子の縦框に対して水平軸まわりに回動可能に取り付け、該第２アームの一端に、他端と逆方向の突出部を設け、該突出部の屋外側面に当接して前記第２アームが前記縦框に対して屋外方向へ回動するのを規制する外方回動規制手段が設けられ、前記縦框に対して上下方向にスライド可能に支持されると共に操作片が設けられた可動ストッパを備え、該操作片により該可動ストッパを上方へスライドさせると、前記第２アームが前記縦框に対して屋外方向へ回動可能となるものであり、前記障子を閉じた状態で、前記操作片が前記気密材を弾性変形させて前記縦枠体及び縦框体の対向面間の隙間を通過可能なように、前記操作片を薄板状として左右方向の外方へ延出させ、さらに屋内方向へ屈曲させてなり、該操作片により前記可動ストッパを前記障子の屋内側から操作可能となしたので、簡素な構成により、断熱内倒し窓の気密性を確保することができると共に操作性が良い断熱内倒し窓用ステーを得ることができる。また、長期にわたり小角度傾倒位置又は大角度傾倒位置とする動作の高い信頼性を確保することができる。さらに、コスト低減化を図ることができる。さらにまた、断熱内倒し窓を閉じた状態において、障子の縦枠の屋内側面に開口部及び操作つまみがなく、窓枠の縦枠と障子の縦框の間の薄肉の操作つまみが視認されるのみであるため、断熱内倒し窓全体の外観がすっきりとした印象となる。 According to the heat-insulating inward window stay according to the present invention, the opposing surfaces of the frame and the casing are formed on each of the upper and lower and left and right frames of the window frame and the upper and lower and left and right casings of the shoji. A stay used for a heat-insulating inward window provided with an airtight material that closes the gap between the opposing surfaces on at least one of the surfaces, and rotates one end of the first arm and one end of the second arm around a horizontal axis. The other end of the first arm is attached to the vertical frame of the window frame so as to be rotatable about a horizontal axis and slidable in the vertical direction, and the other end of the second arm is connected to the shoji The second arm is provided with a protrusion in the opposite direction to the other end, and is in contact with the outdoor side surface of the protrusion so that the second arm An outward rotation restricting means for restricting rotation in the outdoor direction with respect to the vertical shaft is provided, And a movable stopper provided with an operation piece. When the movable stopper is slid upward by the operation piece, the second arm is outdoors with respect to the downspout. The operation piece can elastically deform the hermetic material and pass through the gap between the opposing surfaces of the vertical frame body and the vertical frame body with the shoji screen closed. In addition, the operation piece is formed in a thin plate shape, extending outward in the left-right direction, and further bent in the indoor direction, and the operation piece enables the movable stopper to be operated from the indoor side of the shoji. With this configuration, it is possible to obtain a heat-insulating inward window stay that can secure the airtightness of the heat-insulating inward window and has good operability. In addition, high reliability in the operation of setting the small angle tilt position or the large angle tilt position over a long period of time can be ensured. Furthermore, cost reduction can be achieved. Furthermore, in the state where the heat-insulated inside-down window is closed, there is no opening or operation knob on the indoor side of the vertical frame of the shoji, and a thin operation knob between the vertical frame of the window frame and the vertical shovel of the shoji is visible. As a result, the overall appearance of the window will be a clean impression.

A washer made of nylon or the like is mounted between the head of the stepped rivet 48 and the first arm 51 and around the shaft of the stepped rivet 48 between the first arm 51 and the second arm 52. Thus, the rotation operation around the horizontal axis is facilitated.

段付リベット４７を、窓枠取付板４３の長孔４３ｂ及び第１アーム５１の他端の通孔５１ｂを通して軸端をかしめることにより、第１アーム５１の他端は、窓枠２の縦枠２３，２４して水平軸まわりに回動可能にかつ上下方向にスライド可能に取り付けられる。また、段付リベット４９を、第２アーム５２の他端の通孔５２ｂ及び障子取付板４４の通孔４４ｂを通して軸端をかしめることにより、第２アーム５２の他端は、障子３の縦框３３，３４に対して水平軸まわりに回動可能に取り付けられる。 By caulking the shaft end of the stepped rivet 47 through the long hole 43 b of the window frame mounting plate 43 and the through hole 51 b of the other end of the first arm 51, the other end of the first arm 51 is vertically aligned with the window frame 2. The frames 23 and 24 are attached so as to be rotatable around a horizontal axis and slidable in the vertical direction. In addition, the shaft end of the stepped rivet 49 is caulked through the through hole 52 b at the other end of the second arm 52 and the through hole 44 b of the shoji attachment plate 44, so that the other end of the second arm 52 is It is attached to the flanges 33 and 34 so as to be rotatable around a horizontal axis.

障子取付板４４は、可動ストッパ６１のガイド溝６１ｂに係合し、該ガイド溝６１ｂの前後面が障子取付板４４の前後側面に当接する。したがって、可動ストッパ６１は、障子取付板４４に対する前後方向の移動が規制され、障子取付板４４（障子３の縦框３３，３４）に対して上下方向にスライド可能となっている。 The shoji attachment plate 44 engages with the guide groove 61 b of the movable stopper 61, and the front and rear surfaces of the guide groove 61 b come into contact with the front and rear sides of the shoji attachment plate 44. Therefore, the movable stopper 61 is restricted from moving in the front-rear direction with respect to the shoji attachment plate 44, and can be slid in the vertical direction with respect to the shoji attachment plate 44 (the vertical rods 33 and 34 of the shoji 3).

可動ストッパ６１のばね収容部６７内には圧縮コイルばね６８が収容され、該圧縮コイルばね６８の上側には、障子取付板４４のばね受け４５がばね収容部６７内に突出している。したがって、可動ストッパ６１には圧縮コイルばね６８の復元力による下方への付勢力が作用している。また、可動ストッパ６１の係合孔６９ａに操作片６２の係合片７０ａが係合し、可動ストッパ６１の係止孔６９ｂに操作片６２の係止片７０ｂが係止する。そして、取付ねじ６６が、通孔６１ａを通され螺孔６２ａに螺合するため、可動ストッパ６１と操作片６２とは強固に連結されて一体化する。 A compression coil spring 68 is accommodated in the spring accommodating portion 67 of the movable stopper 61, and a spring receiver 45 of the shoji mounting plate 44 projects into the spring accommodating portion 67 above the compression coil spring 68. Therefore, the downward biasing force due to the restoring force of the compression coil spring 68 acts on the movable stopper 61. Further, the engagement piece 70 a of the operation piece 62 is engaged with the engagement hole 69 a of the movable stopper 61, and the engagement piece 70 b of the operation piece 62 is engaged with the engagement hole 69 b of the movable stopper 61. Since the mounting screw 66 passes through the through hole 61a and is screwed into the screw hole 62a, the movable stopper 61 and the operation piece 62 are firmly connected and integrated.

第２アーム５２の一端の通孔５２ａ近傍には、他端の通孔５２ｂ方向と逆方向に突出する突出部５３が設けられている。また、可動ストッパ６１には、該突出部５３の屋内側面５４に当接して第２アーム５２が縦框３３，３４に対して屋内方向へ回動することを規制する内方回動規制手段５６、及び、該突出部５３の屋外側面５５に当接して第２アーム５２が縦框３３，３４に対して屋外方向へ回動するのを規制する外方回動規制手段５７が設けられている。 In the vicinity of the through hole 52a at one end of the second arm 52, a protruding portion 53 is provided that protrudes in the direction opposite to the direction of the through hole 52b at the other end. In addition, the movable stopper 61 abuts against the indoor side surface 54 of the projecting portion 53 and restricts the second arm 52 from rotating in the indoor direction with respect to the vertical rods 33, 34. In addition, an outward rotation restricting means 57 is provided which abuts against the outdoor side surface 55 of the protruding portion 53 and restricts the second arm 52 from rotating in the outdoor direction with respect to the vertical rods 33 and 34. .

したがって、可動ストッパ６１の外方回動規制手段５７が第２アーム５２の突出部５３の屋外側面５５に当接して、第２アーム５２の縦框３３，３４（障子取付板４４）に対する屋外方向への回動が規制された状態（図６参照。）では、障子３は図４の小角度傾倒位置Ｂまでしか傾倒しない。これに対して、図８に示すように操作片６２を操作して、可動ストッパ６１を上方へスライドさせると（図中矢印Ｄ参照。）、第２アーム５２が縦框３３，３４（障子取付板４４）に対して屋外方向へ回動可能となるため、障子３は図４の大角度傾倒位置Ｃまで傾倒する。 Therefore, the outward rotation restricting means 57 of the movable stopper 61 contacts the outdoor side surface 55 of the protrusion 53 of the second arm 52, and the outdoor direction of the second arm 52 with respect to the vertical rods 33 and 34 (the shoji attachment plate 44). In the state where the rotation to the side is restricted (see FIG. 6), the shoji 3 tilts only to the small angle tilt position B in FIG. On the other hand, when the operation piece 62 is operated as shown in FIG. 8 and the movable stopper 61 is slid upward (refer to the arrow D in the figure), the second arm 52 has the vertical rods 33 and 34 (the shoji attachment). The shoji 3 is tilted to the large-angle tilt position C in FIG.

したがって、断熱内倒し窓１の障子３を、防犯上問題のない小角度傾倒位置Ｂまでの傾倒角度から、該障子３の屋外面を屋内側から掃除可能なように、大角度傾倒位置Ｃまでの傾倒角度へ容易に変更することができる。また、障子取付板４４にはアーム受け４６が形成されており、第２アーム５２の障子３の縦框３３、３４（障子取付板４４）に対する屋外方向への回動が所定角度までで規制されるため、第１アーム５１及び第２アーム５２の一端同士を回動可能に連結したリンク機構の動作の安定化を図ることができるため、障子３の開閉動作の安定化を図ることができる。さらに、アーム受け４６の位置により大角度傾倒位置Ｃでの障子３の傾倒角度を調整することができる。なお、障子取付板４４に前後対称にアーム受け４６，４６を形成しているのは、左ステー４１及び右ステー４２において、同一形状の部品を共用するためである。 Therefore, the shoji 3 of the heat-insulating inward window 1 is moved from the tilt angle to the small-angle tilt position B, which has no problem in crime prevention, to the large-angle tilt position C so that the outdoor surface of the shoji 3 can be cleaned from the indoor side. The tilt angle can be easily changed. Moreover, the arm receiver 46 is formed in the shoji attachment plate 44, and the rotation of the second arm 52 in the outdoor direction with respect to the vertical rods 33 and 34 (the shoji attachment plate 44) of the shoji 3 is restricted to a predetermined angle. Therefore, since the operation of the link mechanism in which the ends of the first arm 51 and the second arm 52 are rotatably connected can be stabilized, the opening / closing operation of the shoji 3 can be stabilized. Further, the tilt angle of the shoji 3 at the large-angle tilt position C can be adjusted by the position of the arm receiver 46. The reason why the arm receivers 46 and 46 are formed symmetrically on the shoji mounting plate 44 is that the left stay 41 and the right stay 42 share parts of the same shape.

図５、図６及び図８に示すように、突出部５３の屋外側面５５は略垂直平面であり、突出部５３の屋内側面５４は上方に行くにしたがって前方へ傾斜する曲面（略円筒面）となっている。また、可動ストッパ６１は、前記のとおり圧縮コイルばね６８による下方への付勢力が作用した状態で上下方向にスライド可能となっている。したがって、障子３を図４の大角度傾倒位置Ｃから小角度傾倒位置Ｂまで戻す場合には、取手１２を持って障子３を前方（屋外方向）へ押し上げて回動支持部６まわりに回動させれば、可動ストッパ６１の前下部に突出部５３の屋内側面５４が当接し、該可動ストッパ６１が押し上げられる（例えば、図８参照。）。そして、障子３が図４の小角度傾倒位置Ｂに達すると、可動ストッパ６１が下降して、外方回動規制手段５７が突出部５３の屋外側面５５に位置するため、第２アーム５２の縦框３３，３４に対する屋外方向への回動が規制され（図６参照。）、該状態が保持される。 As shown in FIGS. 5, 6, and 8, the outdoor side surface 55 of the protrusion 53 is a substantially vertical plane, and the indoor side surface 54 of the protrusion 53 is a curved surface (substantially cylindrical surface) that is inclined forward as it goes upward. It has become. The movable stopper 61 is slidable in the vertical direction with the downward biasing force applied by the compression coil spring 68 as described above. Therefore, when the shoji 3 is returned from the large-angle tilt position C to the small-angle tilt position B in FIG. 4, the shoji 3 is pushed forward (outdoor direction) by holding the handle 12 and rotated around the rotation support portion 6. If it does, the indoor side surface 54 of the protrusion part 53 will contact | abut to the front lower part of the movable stopper 61, and this movable stopper 61 will be pushed up (for example, refer FIG. 8). When the shoji 3 reaches the small-angle tilt position B in FIG. 4, the movable stopper 61 is lowered and the outward rotation restricting means 57 is located on the outdoor side surface 55 of the protruding portion 53. The rotation of the vertical rods 33 and 34 in the outdoor direction is restricted (see FIG. 6), and this state is maintained.

次に、本発明の実施の形態に係る断熱内倒し窓用ステー４１，４２の操作片６２の形状について説明する。操作片６２は、障子３を閉じた状態（図３及び図４の閉状態Ａ参照。）で、該操作片６２が屋内側気密材３０を弾性変形させて縦枠２３，２４及び縦框３３，３４の対向面２６，３６間の隙間を通過可能なように、薄板状に形成されている。そして、該操作片６２は、左右方向の外方へ延出する外方延出部６３、及び、前記隙間を通過後に屋内方向に屈曲する屋内方向屈曲部６４が形成されている。そして、該屋内方向屈曲部６４に外嵌する操作つまみ６５の係止孔６５ａに屋内方向屈曲部６４の係止片６４ａが係止し、操作つまみ６５は操作片６２に取り付けられる。 Next, the shape of the operation piece 62 of the heat-insulating inward window stays 41 and 42 according to the embodiment of the present invention will be described. The operation piece 62 is in a state in which the shoji 3 is closed (see the closed state A in FIGS. 3 and 4), and the operation piece 62 elastically deforms the indoor airtight material 30 and the vertical frames 23 and 24 and the vertical rod 33. , 34 is formed in a thin plate shape so that it can pass through the gap between the opposing surfaces 26, 36. The operation piece 62 includes an outward extending portion 63 that extends outward in the left-right direction, and an indoor-direction bent portion 64 that bends in the indoor direction after passing through the gap. Then, the locking piece 64 a of the indoor direction bending portion 64 is locked in the locking hole 65 a of the operation knob 65 that fits outside the indoor direction bending portion 64, and the operation knob 65 is attached to the operation piece 62.

このように操作片６２は薄板状であるが、前記のとおり可動ストッパ６１と強固に一体化されていると共に、上下方向には比較的長い形状であるため、該操作片６２の操作方向（上下方向）には剛性及び強度が大きい形状となっている。したがって、操作片６２による可動ストッパ６１を上方にスライドさせるための操作を、屋内側から安定かつ確実に行うことができる。また、該操作片６２は、前記のとおり、障子３を閉じた状態（図３及び図４の閉状態Ａ参照。）で、屋内側気密材３０を弾性変形させて縦枠２３，２４及び縦框３３，３４の対向面２６，３６間の隙間を通過するため、断熱内倒し窓１の気密性が損なわれることはない。また、断熱内倒し窓用ステー４１，４２の構成は、操作片６２も含めて簡素であるため、長期にわたり高い動作信頼性を確保することができると共にコスト低減化を図ることができる。 As described above, the operation piece 62 has a thin plate shape, but is firmly integrated with the movable stopper 61 as described above, and has a relatively long shape in the vertical direction. (Direction) has a shape with high rigidity and strength. Therefore, the operation for sliding the movable stopper 61 upward by the operation piece 62 can be performed stably and reliably from the indoor side. Further, as described above, the operation piece 62 elastically deforms the indoor side airtight member 30 in the state in which the shoji 3 is closed (see the closed state A in FIGS. 3 and 4) and the vertical frames 23 and 24 and the vertical frame Since it passes through the gap between the opposing surfaces 26 and 36 of the flanges 33 and 34, the airtightness of the heat-insulating inward window 1 is not impaired. Moreover, since the structure of the heat insulating inward window stays 41 and 42 including the operation piece 62 is simple, high operational reliability can be secured over a long period of time and cost reduction can be achieved.
