Description

本発明は、障子を閉位置から小角度傾倒位置まで内倒した状態及びさらに大角度傾倒位置まで内倒した状態で保持可能とする内倒し窓用ステーに関するものである。   The present invention relates to an inward-turning window stay that can hold a shoji in a state where it is tilted inward from a closed position to a small angle tilt position and further in a state where it is tilted inward to a large angle tilt 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内倒し窓用ステーとして、窓枠の縦枠内側面に取り付けられる窓枠取付板と、該窓枠取付板に対し、枠側連結手段により左右方向軸まわりに回動可能にかつ上下方向にスライド可能に一端が取り付けられた第1アームと、障子の縦框外側面に取り付けられる障子取付板と、該障子取付板に対し、框側連結手段により左右方向軸まわりに回動可能に一端が取り付けられた第2アームと、前記第1アーム及び第2アームの他端を左右方向軸まわりに回動可能に連結するアーム連結手段と、前記障子取付板に対して上下方向にスライド可能に支持されるとともに操作片が室内側に設けられ、前記第2アームの前記障子取付板に対する屋外方向への回動を規制する外方回動規制手段が設けられた可動ストッパとを備え、前記操作片により前記可動ストッパを上方へスライドさせることにより、前記第2アームを前記縦框に対して屋外方向へ回動可能としてなるものがある(例えば、特許文献1及び2参照。)。   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. A window frame mounting plate that is attached to the inner surface of the vertical frame of the window frame as an inward-turning stay, and the window frame mounting plate can be pivoted about the left-right axis by the frame side connecting means and slid vertically.

実用新案登録第2550540号公報(図1−2)Utility Model Registration No. 2550540 (Fig. 1-2) 特開2006−257782号公報(図1、図4−5)JP 2006-257782 A (FIGS. 1 and 4-5)

以上のような従来の内倒し窓用ステーは、例えば図8に示す従来のステー41における枠側連結手段42、框側連結手段43及びアーム連結手段44として、長期間にわたる動作の信頼性の確保及びコスト低減等のために、これら連結手段42,43,44の3箇所の締結部の孔にそれぞれリベットの軸部を差し込み、軸端をかしめて継手とするリベット継手を用いているとともに、かしめ工程により前記締結部に摩擦抵抗を発生させるようにして一定の作動力を付与している。
このような構成の内倒し窓用ステーを用いた内倒し窓において、前記3箇所のリベット継手の作動力のバランスが取れた状態では、図8(a)に示すように、閉位置Aから障子3の屋外面の掃除等のために大角度傾倒位置Cとした後に、障子3を前方(屋外方向)へ押し上げると、枠側連結手段42が窓枠取付板45の上下方向の長孔45Aの上端部に保持された状態(図8(a)のイ参照。)で障子3が回動するため、必ず小角度傾倒位置Bになる。そして、小角度傾倒位置Bから障子3を前方(屋外方向)へ押し上げると枠側連結手段42が窓枠取付板45の上下方向の長孔45Aに沿って長孔45Aの下端部まで移動して閉位置Aになる。
The conventional inward window stay as described above, for example, as the frame side connecting means 42, the heel side connecting means 43 and the arm connecting means 44 in the conventional stay 41 shown in FIG. In order to reduce costs and the like, a rivet joint is used in which the shaft portion of the rivet is inserted into the holes of the three fastening portions of the connecting means 42, 43, and 44, and the shaft ends are caulked. A certain operating force is applied so as to generate a frictional resistance in the fastening portion by the process.
When the operating force of the three rivet joints is balanced in the inward window using the inward window stay having such a configuration, as shown in FIG. After the shovel 3 is pushed forward (outdoor direction) after the large-angle tilt position C is set for cleaning the outdoor surface 3 and the like, the frame-side connecting means 42 causes the vertical slot 45A of the window frame mounting plate 45 to Since the shoji 3 is rotated while being held at the upper end (see (a) of FIG. 8A), it is always in the small-angle tilt position B. When the shoji 3 is pushed forward (outdoor direction) from the small-angle tilt position B, the frame side connecting means 42 moves to the lower end of the long hole 45A along the vertical hole 45A in the vertical direction of the window frame mounting plate 45. Closed position A is reached.

これに対して、前記3箇所のリベット継手の作動力のバランスが取れていない状態では、図8(b)に示すように、大角度傾倒位置Cから障子3を前方(屋外方向)へ押し上げる際に、枠側連結手段42が窓枠取付板45の上下方向の長孔45Aの上端部に保持されずに矢印Fのように下方へ移動してしまい(図8(b)のロ参照。)、位置Dに示すように小角度傾倒位置Bに保持された状態とはならない不都合が生じる。   On the other hand, when the operating force of the three rivet joints is not balanced, the shoji 3 is pushed forward (outdoor direction) from the large-angle tilt position C as shown in FIG. In addition, the frame-side connecting means 42 moves downward as indicated by an arrow F without being held by the upper end of the vertical hole 45A in the vertical direction of the window frame mounting plate 45 (see B in FIG. 8B). As shown in the position D, there arises a disadvantage that the small angle tilt position B is not maintained.

したがって、従来の内倒し窓用ステーのように、枠側連結手段、框側連結手段及びアーム連結手段の3箇所ともにリベット継手とした構成では、内倒し窓を滑らかに動作させるために、前記3箇所のリベット継手の作動力が大きくなり過ぎないようにするとともにバランスを取る必要があるため、例えば前記3箇所の作動力の規格を設定し、その規格内に入るようにかしめ荷重及びかしめ量を管理する必要があり、このような作動力を調整するための管理に手間が掛かるとともに、かしめ工程後には分解することができないため歩留りが下がっている。
その上、このように管理したステーを出荷後に、窓枠に実際にステー及び障子を取り付けた後に内倒し窓が滑らかに動作しない場合もあり、このような場合においても前記作動力の調整ができないことからステーを交換する必要が生じるため、内倒し窓の施工時間が必要以上に掛かってしまう場合がある。
よって、前記内倒し窓用ステーは、窓枠取付板を縦枠にねじ止めするとともに、障子を障子取付板にねじ止めすることによって容易に組付け作業を行うことができること等の特徴を有するものであるが、前記枠側連結手段、框側連結手段及びアーム連結手段の構成には、改良の余地がある。
Therefore, in a configuration in which rivet joints are used at all three positions of the frame side connecting means, the heel side connecting means, and the arm connecting means as in the conventional inward window stay, the above described 3 Since it is necessary to balance the operating force of the rivet joint at the location, it is necessary to balance it. For example, the standard of the operating force at the three locations is set, and the caulking load and the caulking amount are set so as to be within the standard. It is necessary to manage, and it takes time and effort to adjust the operating force, and the yield is lowered because it cannot be disassembled after the caulking process.
In addition, after the stays managed in this way are shipped, the tilted window may not operate smoothly after the stay and the shoji are actually attached to the window frame. In such a case, the operating force cannot be adjusted. Therefore, it is necessary to replace the stay, so that it may take more time than necessary to install the fallen window.
Therefore, the stay for inward windows has features such that the window frame mounting plate can be screwed to the vertical frame and the assembling work can be easily performed by screwing the shoji to the shoji mounting plate. However, there is room for improvement in the configuration of the frame side connecting means, the heel side connecting means, and the arm connecting means.

そこで本発明が前述の状況に鑑み、解決しようとするところは、窓枠取付板を縦枠にねじ止めするとともに、障子を障子取付板にねじ止めすることによって容易に組付け作業を行うことができる構成でありながら、施工時に内倒し窓を滑らかに動作させるように調整することができる内倒し窓用ステーを提供する点にある。   Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that the window frame mounting plate is screwed to the vertical frame and the shoji is easily screwed to the shoji mounting plate. The object is to provide a stay for an inward-turning window that can be adjusted so that the inward-turning window can be operated smoothly during construction, even though the structure can be made.

According to the inward window stay according to the present invention, the window frame mounting plate attached to the inner surface of the vertical frame of the window frame, and the window frame mounting plate can be rotated around the left and right axis by the frame side connecting means. And a first arm with one end attached so as to be slidable in the vertical direction, a shoji attachment plate attached to the longitudinal outer surface of the shoji, and the shoji attachment means. A second arm having one end movably attached thereto, an arm connecting means for connecting the other end of the first arm and the second arm to be rotatable about a left-right axis, and a vertical direction with respect to the shoji mounting plate And a movable stopper provided with an operation piece provided on the indoor side and provided with an outward rotation restricting means for restricting rotation of the second arm relative to the shoji mounting plate in the outdoor direction. Steer for internal fall window provided The heel side coupling means includes a left and right round hole formed in the shoji mounting plate, a left and right round hole formed at one end of the second arm, and a shaft portion inserted into the round hole. The arm connecting means includes a left and right round hole formed at the other end of the first arm and a right and left formed at the other end of the second arm. Direction round holes and rivets having shaft portions inserted into the round holes and caulked at the shaft ends thereof, and the frame side connecting means penetrates in the left and right direction formed in the window frame mounting plate and vertically A left and right round hole formed at one end of the first arm, and located on the opposite side of the first arm with respect to the window frame mounting plate, and the rotation about the left and right axis is restricted. Up and down direction along the window frame mounting plate in the state A slide body that slides, and a left-right adjustment bolt that is screwed into a screw hole of the slide body or a nut that is abutted against the slide body, with the head being abutted against the first arm directly or via a washer Since the window frame mounting plate is screwed to the vertical frame and the shoji mounting plate is screwed to the vertical rod, the assembling work can be easily performed and the existing window The frame can be knocked down and applied to the window.
In addition, when attached to the inward window, the shoji can be held in a state where the shoji is tilted from the closed position to a small angle tilt position where there is no problem in crime prevention. By sliding upward against the elastic biasing force, the second arm can be rotated in the outdoor direction with respect to the shoji mounting plate, so that the shoji can be further cleaned so that the outdoor surface can be cleaned from the indoor side. It can be held in a tilted position up to a large angle tilt position.
Furthermore, the window frame mounting plate can be easily removed from the vertical frame, and the shoji mounting plate can be easily detached from the shoji, so that the maintenance or replacement of the stay or shoji can be easily performed. .

その上、調整ボルトの締付け力を調整して第1ワッシャ及び第2ワッシャに挟まれた第1アームに対する左右方向の押圧力並びにスライド体の窓枠取付板への左右方向の押圧力を調整することにより、第1アームが窓枠取付板に対して左右方向軸まわりに回動する際の作動力及び第1アームが窓枠取付板に対して上下方向にスライドする際の作動力を容易に調整することができるため、框側連結手段のリベット継手の一定の作動力及びアーム連結手段のリベット継手の一定の作動力に対して、調整ボルトにより枠側連結手段の作動力を調整することができる。
よって、施工の際に、内倒し窓を滑らかに動作させるように調整ボルトにより容易に調整することができるため、組み付け後の不具合を無くすことができる。
その上さらに、枠側連結手段の作動力を調整ボルトにより調整することができることから、框側連結手段のリベット継手の作動力及びアーム連結手段のリベット継手の作動力の規格(設定範囲)を広げることができるため、ステー単体の組立調整及び出荷時の管理が容易になる。
その上、施工後に内倒し窓を使用し、摩耗等による経時変化によりステーの框側連結手段のリベット継手の作動力及びアーム連結手段のリベット継手の作動力並びに枠側連結手段の作動力が変動して内倒し窓が滑らかに動作しなくなった場合においても、調整ボルトによる調整により内倒し窓が滑らかに動作する状態に容易に復帰させることができる。
In addition, by adjusting the tightening force of the adjustment bolt, the lateral pressing force on the first arm sandwiched between the first washer and the second washer and the lateral pressing force on the window frame mounting plate of the slide body are adjusted. This facilitates the operating force when the first arm rotates about the left-right axis relative to the window frame mounting plate and the operating force when the first arm slides up and down relative to the window frame mounting plate. Therefore, the adjusting bolt can be used to adjust the operating force of the frame side connecting means with respect to the constant operating force of the rivet joint of the heel side connecting means and the constant operating force of the rivet joint of the arm connecting means. it can.
Therefore, since it can be easily adjusted by the adjustment bolt so that the inward-turning window can be operated smoothly at the time of construction, problems after assembly can be eliminated.
Furthermore, since the operating force of the frame side connecting means can be adjusted by the adjusting bolt, the standards (setting range) of the operating force of the rivet joint of the heel side connecting means and the operating force of the rivet joint of the arm connecting means are expanded. As a result, the assembly adjustment of the stay unit and the management at the time of shipment become easy.
In addition, the inversion window is used after construction, and the operating force of the rivet joint of the heel side connecting means, the operating force of the rivet joint of the arm connecting means, and the operating force of the frame side connecting means fluctuate due to changes over time due to wear etc. Even when the inward-turning window does not operate smoothly, it is possible to easily return to the state in which the inward-turning window operates smoothly by adjustment with the adjustment bolt.

また、前記枠側連結手段が、前記窓枠取付板に形成された左右方向に貫通し上下方向に延びる長孔、前記第1アームの一端に形成された左右方向の丸孔、前記窓枠取付板に対して前記第1アームと反対側に位置し、左右方向軸まわりの回転が規制された状態で前記窓枠取付板に沿って上下方向にスライドするスライド体、前記第1アーム一端の丸孔に内接する多角形状外側面を有し左右方向の通孔が形成された筒体、該筒体が嵌合する、前記スライド体に形成された左右方向の多角形状孔、前記窓枠取付板と前記第1アームとの間に介在し、前記筒体に外嵌する多角形状孔が形成された第1ワッシャ、該第1ワッシャとともに前記第1アームを挟む、前記筒体に外嵌する多角形状孔が形成された第2ワッシャ、並びに、該第2ワッシャに頭部が当止され、前記スライド体の螺孔又は前記スライド体に当止されるナットに螺合した左右方向の調整ボルトにより構成されると、前記効果に加え、第1アーム一端の丸孔に内接する筒体が左右方向軸まわりの回転が規制された状態で窓枠取付板に沿って上下方向にスライドするスライド体と一体化されていることから、第1アームが左右方向軸まわりに回動しても筒体は回動しないとともに、第1ワッシャ及び第2ワッシャも、筒体の多角形状外側面に外嵌しているため、第1アームの動きにつられて左右方向軸まわりに回動することがない。
よって、第2ワッシャに頭部が押圧される調整ボルトが、第1アームの回動により影響を受けないことから、第1アームの回動により調整ボルトが緩まないため、調整が完了した状態を長期にわたって安定かつ確実に保持することができる。
In addition, the frame side connecting means includes a long hole penetrating in the horizontal direction formed in the window frame mounting plate and extending in the vertical direction, a round hole in the horizontal direction formed at one end of the first arm, and the window frame mounting. A slide body that is positioned on the opposite side of the plate from the first arm and that slides up and down along the window frame mounting plate in a state in which rotation about a left-right axis is restricted; Cylindrical body having a polygonal outer surface inscribed in the hole and having left and right through holes formed therein, a horizontal polygonal hole formed in the slide body into which the cylindrical body is fitted, and the window frame mounting plate And a first washer formed between the first arm and a polygonal hole that fits into the cylinder, and a polygon that fits around the cylinder, sandwiching the first arm with the first washer. A second washer having a shape hole, and a head on the second washer In addition to the above-described effect, if it is constituted by a left and right adjustment bolt screwed to a screw hole of the slide body or a nut to be held against the slide body, it is inscribed in a round hole at one end of the first arm. Since the cylindrical body is integrated with a slide body that slides up and down along the window frame mounting plate in a state where rotation about the left-right axis is restricted, the first arm rotates about the left-right axis. However, the cylindrical body does not rotate, and the first washer and the second washer are also fitted on the outer side of the polygonal shape of the cylindrical body. Therefore, the cylindrical body rotates about the left-right axis as the first arm moves. There is nothing.
Therefore, since the adjustment bolt whose head is pressed against the second washer is not affected by the rotation of the first arm, the adjustment bolt is not loosened by the rotation of the first arm. It can be held stably and reliably over a long period of time.

さらに、前記筒体を前記スライド体と一体に形成してなると、前記効果に加え、枠側連結手段の部品点数を削減することができるためコストを削減することができる。   Further, when the cylindrical body is formed integrally with the slide body, in addition to the above effects, the number of parts of the frame side connecting means can be reduced, so that the cost can be reduced.

次に本発明の実施の形態を添付図面に基づき詳細に説明するが、本発明は、添付図面に示された形態に限定されず特許請求の範囲に記載の要件を満たす実施形態の全てを含むものである。なお、本明細書においては、屋内側から屋外側へ向かう方向の前側を前、後側を後とし、左右は前方に向かっていうものとする。また、障子については、最も閉じた状態において前記方向の定義を用いる。   Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図1に示すように、窓枠2は、上枠2U、下枠2L及び左右の縦枠2S,2Sを組み合わせてなる矩形枠体等からなり、障子3は、上框3U、下框3L及び左右の縦框3S,3Sを組み合わせてなる矩形框体並びに該框体内側の窓開口部に装着されるガラス等からなる。
また、内倒し窓1は、窓枠2及び窓枠2内に納められる障子3、窓枠1の左右の縦枠2S,2S内側面及び左右の縦框3S,3S外側面間に取り付けた左右のステー等からなり、下枠2Lの左右方向に延びる窓枠側支持部5及び該窓枠側支持部5に外嵌する障子側支持部6により構成される回動支持部4まわりに障子3を屋内側へ傾倒可能に構成したものであり、上框3Uに設けた取手8の操作により、窓枠2の上枠2Uに取り付けた係止部10とラッチ機構7のラッチ具9との係止が解除され、障子3が閉位置Aから小角度傾倒位置Bまで屋内側へ傾倒可能となる。
As shown in FIG. 1, the window frame 2 includes a rectangular frame formed by combining an upper frame 2U, a lower frame 2L, and left and right vertical frames 2S, 2S, and the shoji 3 includes an upper frame 3U, a lower frame 3L, and It consists of the rectangular housing | casing which combined right and left vertical rod 3S, 3S, the glass etc. which are mounted | worn with the window opening part inside this housing.
The inward-turning window 1 includes a window frame 2 and a shoji 3 that is housed in the window frame 2, left and right vertical frames 2S and 2S inner side surfaces of the window frame 1, and left and right vertical rods 3S and 3S attached between the outer side surfaces. The shoji 3 around the pivot support 4 is composed of a window frame side support 5 extending in the left-right direction of the lower frame 2L, and a shoji side support 6 fitted to the window frame side support 5. Can be tilted to the indoor side, and the engagement between the locking portion 10 attached to the upper frame 2U of the window frame 2 and the latching tool 9 of the latch mechanism 7 by the operation of the handle 8 provided on the upper frame 3U. The stop is released, and the shoji 3 can be tilted indoors from the closed position A to the small-angle tilt position B.

例えば、取手8を下げると、図示しないばねによる復元力により上方へ付勢されているラッチ具9を下降させる力が作用して、係止部10とラッチ具9との係止が解除され、図1の閉位置Aから小角度傾倒位置Bまで屋内側へ傾倒可能となる。そして、障子3は、後述する操作片17Aの操作により、さらに大角度傾倒位置Cまで屋内側へ傾倒させることができる。
また、障子3を閉じる際には、取手8を持って障子3を前方(屋外方向)へ押し上げて前記回動支持部4まわりに回動させることにより、ラッチ具9の傾斜面9Aが係止部10により押し下げられて係止部10を通過後、上方へ付勢力が作用しているラッチ具9が閉位置Aにて上昇して係止部10の前面により係止されるため、閉位置Aにて施錠状態となる。
For example, when the handle 8 is lowered, a force that lowers the latch tool 9 that is biased upward by a restoring force by a spring (not shown) is applied, and the locking between the locking portion 10 and the latch tool 9 is released, It is possible to tilt indoors from the closed position A to the small-angle tilt position B in FIG. The shoji 3 can be further tilted indoors to the large-angle tilt position C by operating the operation piece 17A described later.
Further, when closing the shoji 3, the inclined surface 9A of the latch 9 is locked by pushing the shoji 3 forward (outdoor direction) by holding the handle 8 and turning it around the turning support 4. After the latch 10 is pushed down by the portion 10 and passes through the locking portion 10, the latching tool 9 acting upwardly is lifted at the closed position A and locked by the front surface of the locking portion 10. A is locked.

次に、本発明の実施の形態に係る内倒し窓用ステーについて説明するが、左右のステーは左右対称であり同様の構成であるため、左ステー11を代表させて説明する。
図1、図3及び図4に示すように、左ステー11の窓枠取付板21及び障子取付板22は上下方向に縦長に形成されており、窓枠取付板21は、その上下に位置する左右方向の丸孔21A,21Aを用いて窓枠2の縦枠2Sに取り付けられ、障子取付板22は、その上下に位置する左右方向の丸孔22A,22Aを用いて障子3の縦框3Sに取り付けられる。
第1アーム31は、その一端が窓枠取付板21に対し、枠側連結手段12により左右方向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、第2アーム32は、その一端が障子取付板22に対し、框側連結手段13によ左右方向軸まわりに回動可能に取り付けられ、第1アーム31及び第2アーム32の他端は、アーム連結手段14により左右方向軸まわりに回動可能に連結され、第2アーム32の他端の左右方向の丸孔32A近傍には、前記一端の左右方向の丸孔32Bに向かう方向と逆方向に突出する突出部33が設けられる。
Next, the inward window stay according to the embodiment of the present invention will be described. Since the left and right stays are symmetrical and have the same configuration, the left stay 11 will be described as a representative.
As shown in FIGS. 1, 3, and 4, the window frame mounting plate 21 and the shoji mounting plate 22 of the left stay 11 are formed vertically long in the vertical direction, and the window frame mounting plate 21 is positioned above and below the window frame mounting plate 21. It is attached to the vertical frame 2S of the window frame 2 using the round holes 21A, 21A in the left-right direction, and the shoji mounting plate 22 is installed in the vertical rod 3S of the shoji 3 using the round holes 22A, 22A in the left-right direction located above and below it. Attached to.
One end of the first arm 31 is attached to the window frame mounting plate 21 so as to be rotatable about the left-right axis and slidable in the vertical direction by the frame side connecting means 12, and the second arm 32 is attached to one end thereof. There to shoji mounting plate 22, by Ri pivotally mounted about the horizontal direction axis rail-side coupling means 13, the other end of the first arm 31 and second arm 32, the left-right axis by the arm connecting means 14 A protrusion 33 is provided in the vicinity of the left and right round holes 32 </ b> A at the other end of the second arm 32 so as to be pivotable around and protrudes in a direction opposite to the direction toward the left and right round holes 32 </ b> B at the one end. It is done.

障子取付板22には、可動ストッパ17が上下方向にスライド可能に支持されるとともに、ばね受け23の下側の圧縮コイルばね18(図4参照。)により可動ストッパ17は下方へ弾性付勢され、さらに可動ストッパ17にはその室内側に操作片17Aが取り付けられる。
また、可動ストッパ17には、第2アーム32の突出部33の屋内側面34に当接して障子取付板22(縦框3S)に対する第2アーム32の屋内方向への回動を規制する内方回動規制手段15、及び、前記突出部33の屋外側面35に当接して障子取付板22(縦框3S)に対する第2アーム32の屋外方向への回動を規制する外方回動規制手段16が設けられる。
よって、前述のとおり、図1の小角度傾倒位置Bにおいて、操作片17Aにより可動ストッパ17を前記圧縮コイルばね18の弾性付勢力に抗して上方へスライドさせることにより(図4の矢印E参照。)、第2アーム32が障子取付板22(縦框3S)に対して屋外方向へ回動可能となるため、障子3をさらに大角度傾倒位置Cまで内倒した状態とすることができる。
The movable stopper 17 is supported on the shoji mounting plate 22 so as to be slidable in the vertical direction, and the movable stopper 17 is elastically biased downward by a compression coil spring 18 (see FIG. 4) below the spring receiver 23. Further, an operating piece 17A is attached to the movable stopper 17 on the indoor side.
Further, the movable stopper 17 is an inner side that abuts against the indoor side surface 34 of the protruding portion 33 of the second arm 32 and restricts the rotation of the second arm 32 in the indoor direction relative to the shoji attachment plate 22 (vertical rod 3S). The rotation restricting means 15 and the outward rotation restricting means for restricting the rotation of the second arm 32 in the outdoor direction with respect to the shoji attachment plate 22 (vertical rod 3S) in contact with the outdoor side surface 35 of the protrusion 33. 16 is provided.
Therefore, as described above, at the small angle tilt position B in FIG. 1, the movable stopper 17 is slid upward against the elastic biasing force of the compression coil spring 18 by the operation piece 17A (see arrow E in FIG. 4). .), Since the second arm 32 can be rotated in the outdoor direction with respect to the shoji attachment plate 22 (vertical shaft 3S), the shoji 3 can be further inwardly tilted to the tilted position C at a large angle.

このようにして、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22にはアーム受け24が形成されており、第2アーム32の障子取付板22(縦框3S)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ことから、第1アーム31及び第2アーム32の他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が図られているため、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24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。
In this way, the shoji 3 of the inward window 1 is tilted to a large angle so that the outdoor surface of the shoji 3 can be cleaned from the indoor side from the tilt angle to the small angle tilt position B, which has no problem in crime prevention. The tilt angle up to C can be easily changed.
Further, an arm receiver 24 is formed on the shoji mounting plate 22, and the rotation of the second arm 32 with respect to the shoji mounting plate 22 (vertical shaft 3S) in the outdoor direction is restricted to a predetermined angle. Since the operation of the link mechanism in which the other ends of the first arm 31 and the second arm 32 are rotatably connected is 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 24.

図4に示すように、第2アーム32の突出部33の屋外側面35は略垂直平面であり、突出部33の屋内側面34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17は、前記のとおり圧縮コイルばね18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、図1に示す後述する調整ボルト30による調整が完了した状態において、障子3を大角度傾倒位置Cから小角度傾倒位置Bまで戻す場合には、取手8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4まわりに回動させれば、可動ストッパ17の前下部に突出部53の屋内側面34が当接し、該可動ストッパ17が押し上げられる。そして、障子3が図1の小角度傾倒位置Bに達すると、可動ストッパ17が下降して、外方回動規制手段16が突出部33の屋外側面35の前側に位置するため、第2アーム32の障子取付板22(縦框3S)に対する屋外方向への回動が規制され、該状態が保持される。
As shown in FIG. 4, the outdoor side surface 35 of the protrusion 33 of the second arm 32 is a substantially vertical plane, and the indoor side surface 34 of the protrusion 33 is a curved surface (substantially cylindrical surface) that is inclined forward as it goes upward. It has become. The movable stopper 17 is slidable in the vertical direction with the downward biasing force applied by the compression coil spring 18 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 the state where the adjustment using the adjusting bolt 30 described later shown in FIG. 1 is completed, the shoji 3 is held forward (outdoors) with the handle 8. And the inner side surface 34 of the projecting portion 53 comes into contact with the lower front portion of the movable stopper 17, and the movable stopper 17 is pushed up. When the shoji 3 reaches the small-angle tilt position B in FIG. 1, the movable stopper 17 descends and the outward rotation restricting means 16 is positioned on the front side of the outdoor side surface 35 of the projecting portion 33, so that the second arm The rotation to the outdoor direction with respect to the 32 shoji mounting plates 22 (vertical shaft 3S) is restricted, and this state is maintained.

次に、框側連結手段13及びアーム連結手段14について説明する。
図3及び図4に示すように、障子取付板22には、可動ストッパ17の下側に左右方向の丸孔22Bが形成されており、第2アーム32一端の丸孔32B及び障子取付板22の丸孔22Bに段付リベット20の軸部を差し込み、軸端をかしめることにより、第2アーム32の一端は、障子取付板22に対して左右方向軸まわりに回動可能に取り付けられ、これら障子取付板22に形成された左右方向の丸孔22B及び第2アーム32の一端に形成された左右方向の丸孔32B並びにこれらの丸孔22B,32Bに軸部が挿通され軸端がかしめられた段付リベット20により框側連結手段13が構成される。
Next, the heel side connection means 13 and the arm connection means 14 will be described.
As shown in FIGS. 3 and 4, the shoji mounting plate 22 is formed with a round hole 22 </ b> B in the left-right direction below the movable stopper 17, and the round hole 32 </ b> B at one end of the second arm 32 and the shoji mounting plate 22. By inserting the shaft portion of the stepped rivet 20 into the round hole 22B and caulking the shaft end, one end of the second arm 32 is attached to the shoji attachment plate 22 so as to be rotatable around the left and right axis, The left and right round holes 22B formed in the shoji mounting plate 22, the left and right round holes 32B formed at one end of the second arm 32, and the shaft portions are inserted into the round holes 22B and 32B so that the shaft ends are caulked. The ridge side connecting means 13 is constituted by the stepped rivet 20 formed.

また、第1アーム31他端の第2アーム32との締結部には左右方向の丸孔31Bが形成されており、第1アーム31他端の丸孔31B及び第2アーム32他端の丸孔32Aに段付リベット19の軸部を差し込み、軸端をかしめることにより、第1アーム31及び第2アーム32とは左右方向軸まわりに回動可能に連結され、これら第1アーム31他端に形成された左右方向の丸孔31B及び第2アーム32他端に形成された左右方向の丸孔32A並びにこれらの丸孔31B,32Aに軸部が挿通され軸端がかしめられた段付リベット19によりアーム連結手段14が構成される。
ここで、障子取付板22、第1アーム31及び第2アーム32並びに段付リベット19,20は、例えばステンレス鋼等の鋼製であり、第2アーム32と障子取付板22との間の段付きリベット20の軸まわり、及び、第1アーム31と第2アーム32との間の段付きリベット19の軸まわりには、例えばナイロン等の合成樹脂製のワッシャが装着されるため、前記左右方向軸まわりの回動動作の円滑化及び動作音の静粛化が図られている。
Further, a round hole 31B in the left-right direction is formed in a fastening portion with the second arm 32 at the other end of the first arm 31, and a round hole 31B at the other end of the first arm 31 and a round at the other end of the second arm 32 are formed. By inserting the shaft portion of the stepped rivet 19 into the hole 32A and caulking the shaft end, the first arm 31 and the second arm 32 are connected so as to be rotatable around the left and right axis. Left and right round holes 31B formed at the ends, left and right round holes 32A formed at the other end of the second arm 32, and stepped portions in which the shaft portions are inserted into the round holes 31B and 32A and the shaft ends are caulked. The rivet 19 constitutes the arm connecting means 14.
Here, the shoji mounting plate 22, the first arm 31 and the second arm 32, and the stepped rivets 19 and 20 are made of, for example, stainless steel, and the step between the second arm 32 and the shoji mounting plate 22. Since a washer made of synthetic resin such as nylon is attached around the axis of the attached rivet 20 and around the axis of the stepped rivet 19 between the first arm 31 and the second arm 32, the left-right direction Smooth rotation around the axis and quiet operation noise are achieved.

次に、枠側連結手段12について説明する。
図4〜図7に示すように、窓枠取付板21には、左右方向に貫通し上下方向に延びる長孔21Bが形成され、第1アーム31の一端(縦枠2S側端部)には左右方向の丸孔31Aが形成される。
また、窓枠取付板21の第1アーム31と反対側には、窓枠取付板21の長孔21Bの前後側壁に沿う前後の平行面25B,25Bをガイドとして、左右方向軸まわりの回転が規制された状態で窓枠取付板21に沿って上下方向にスライドするスライド体25が配設され、該スライド体25に形成された左右方向の正六角形状孔25Aには、第1アーム31一端の丸孔31Aに内接する正六角形状外側面26Aを有し左右方向の丸孔26Bが形成された筒体26の左端部が嵌合する。
Next, the frame side connecting means 12 will be described.
As shown in FIGS. 4 to 7, the window frame mounting plate 21 is formed with a long hole 21 </ b> B that penetrates in the left-right direction and extends in the up-down direction, and is formed at one end of the first arm 31 (end on the side of the vertical frame 2 </ b> S). A round hole 31A in the left-right direction is formed.
In addition, on the side opposite to the first arm 31 of the window frame mounting plate 21, rotation about the left and right axis is performed using the front and rear parallel surfaces 25B and 25B along the front and rear side walls of the long hole 21B of the window frame mounting plate 21 as a guide. A slide body 25 that slides in the vertical direction along the window frame mounting plate 21 in a restricted state is disposed, and one end of the first arm 31 is inserted into the right hexagonal hole 25A formed in the slide body 25 in the left-right direction. The left end of the cylindrical body 26 having a regular hexagonal outer surface 26A inscribed in the round hole 31A and having a round hole 26B in the left-right direction is fitted.

そして、窓枠取付板21と第1アーム31との間には、筒体26に外嵌する正六角形状孔27Aが形成された第1ワッシャ27が介在し、第1アーム31の左右面は第1ワッシャ27及び筒体26に外嵌する正六角形状孔28Aが形成された第2ワッシャ28により挟まれ、該第2ワッシャ28に頭部30Aが当止された左右方向の調整ボルト30のねじ軸30Bがスライド体25の左端部に当止される板ナット29の螺孔29Aに螺合する。
このような構成により、第1アーム31の一端が窓枠取付板21に対して左右方向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ため、窓枠取付板21に形成された長孔21B、第1アーム31の一端に形成された左右方向の丸孔31A、スライド体25、筒体26、第1ワッシャ27、第2ワッシャ28、調整ボルト30及び板ナット29により枠側連結手段12が構成される。
なお、図6(a)に示すように、調整ボルト30のねじ軸30B先端は、抜け止めのためにかしめであるが、このようなかしめ工程を無くしてもよい。
Between the window frame mounting plate 21 and the first arm 31, there is a first washer 27 formed with a regular hexagonal hole 27A that fits around the cylindrical body 26. The left and right surfaces of the first arm 31 are The left and right adjustment bolts 30 are sandwiched between a first washer 27 and a second washer 28 formed with a regular hexagonal hole 28A that fits outside the cylindrical body 26, and a head 30A is abutted against the second washer 28. The screw shaft 30 </ b> B is screwed into the screw hole 29 </ b> A of the plate nut 29 that is stopped by the left end portion of the slide body 25.
With such a configuration, one end of the first arm 31 is attached to the window frame mounting plate 21 so as to be rotatable about the left-right axis and slidable in the vertical direction. The frame 21 is connected by a long hole 21B, a left and right round hole 31A formed at one end of the first arm 31, a slide body 25, a cylindrical body 26, a first washer 27, a second washer 28, an adjustment bolt 30 and a plate nut 29. Means 12 are configured.
As shown in FIG. 6 (a), the tip of the screw shaft 30B of the adjustment bolt 30 is caulked to prevent it from coming off, but such caulking step may be eliminated.

ここで、窓枠取付板21、筒体26、調整ボルト30及び板ナット29は、例えばステンレス鋼等の鋼製であり、スライド体25、第1ワッシャ27及び第2ワッシャ28は、例えばナイロン等の合成樹脂製であるため、第1アーム31の一端の窓枠取付板21に対する左右方向軸まわりの回動動作及び上下方向のスライド動作の円滑化及び動作音の静粛化が図られている。   Here, the window frame mounting plate 21, the cylindrical body 26, the adjusting bolt 30 and the plate nut 29 are made of steel such as stainless steel, and the slide body 25, the first washer 27 and the second washer 28 are made of nylon or the like, for example. Therefore, the rotating operation and the sliding operation in the vertical direction with respect to the window frame mounting plate 21 at one end of the first arm 31 and the sliding operation in the vertical direction are smoothed, and the operation sound is reduced.

以上のような枠側連結手段12の構成において、筒体26の外側面は正六角形状に限定されるものではなく、第1アーム31一端の丸孔31Aに内接する多角形状であればよい。
したがって、同様に、スライド体25の正六角形状孔25A、第1ワッシャ27の正六角形状孔27A及び第2ワッシャ28の正六角形状孔28Aは、筒体26が嵌合するように筒体26の外側面の形状に合わせて製作されるものであるため、正六角形状孔25A,27A及び28Aも正六角形状に限定されるものではなく、筒体26の外側面の形状に合わせた多角形状であればよい。
In the configuration of the frame side connecting means 12 as described above, the outer side surface of the cylindrical body 26 is not limited to a regular hexagonal shape, and may be a polygonal shape inscribed in the round hole 31A at one end of the first arm 31.
Therefore, similarly, the regular hexagonal hole 25A of the slide body 25, the regular hexagonal hole 27A of the first washer 27, and the regular hexagonal hole 28A of the second washer 28 are arranged so that the cylindrical body 26 is fitted. Therefore, the regular hexagonal holes 25A, 27A and 28A are not limited to the regular hexagonal shape, but are polygonal shapes that match the shape of the outer side surface of the cylindrical body 26. If it is.

また、筒体26はスライド体25と別体とせずに一体に形成してもよく、この場合は、例えば筒体もスライド体と同じ樹脂製とすればよく、このような構成によれば、枠側連結手段12の部品点数を削減することができるためコストを削減することができる。
さらに、板ナット29もスライド体25と別体とせずに一体に形成してもよく、このような構成である場合には、スライド体25自体に調整ボルト30が螺合する螺孔を形成する必要があるため、スライド体25を金属製とするか、あるいは螺孔を金属インサート品としたインサート成形とすればよい。
さらにまた、筒体26の丸孔26Bは丸孔に限定されるものではなく、調整ボルト30のねじ軸が挿通される通孔であればよい。
Further, the cylindrical body 26 may be formed integrally with the slide body 25 without being separated. In this case, for example, the cylindrical body may be made of the same resin as the slide body. Since the number of parts of the frame side connecting means 12 can be reduced, the cost can be reduced.
Further, the plate nut 29 may be formed integrally with the slide body 25 without being separated from the slide body 25. In such a configuration, a screw hole into which the adjustment bolt 30 is screwed is formed in the slide body 25 itself. Since it is necessary, the slide body 25 may be made of metal, or insert molding with screw holes as metal inserts may be used.
Furthermore, the round hole 26B of the cylindrical body 26 is not limited to a round hole, and may be a through hole through which the screw shaft of the adjustment bolt 30 is inserted.

以上のような枠側連結手段12の構成によれば、調整ボルト30の締付け力をドライバ等の工具を用いて調整することにより、第1ワッシャ27及び第2ワッシャ28に挟まれた第1アーム31に対する左右方向の押圧力並びにスライド体25の窓枠取付板21への左右方向の押圧力を調整することができる。
したがって、框側連結手段13のリベット継手の一定の作動力及びアーム連結手段14のリベット継手の一定の作動力に対して、枠側連結手段12の作動力、すなわち第1アーム31が窓枠取付板21に対して左右方向軸まわりに回動する際の作動力及び第1アーム31が窓枠取付板21に対して上下方向にスライドする際の作動力を調整ボルト30により容易に調整することができる。
よって、施工の際に、内倒し窓1を滑らかに動作させるように調整ボルト30により容易に調整することができるため、組み付け後の不具合を無くすことができる。
According to the configuration of the frame side connecting means 12 as described above, the first arm sandwiched between the first washer 27 and the second washer 28 by adjusting the tightening force of the adjusting bolt 30 using a tool such as a screwdriver. The pressing force in the left-right direction with respect to 31 and the pressing force in the left-right direction on the window frame mounting plate 21 of the slide body 25 can be adjusted.
Therefore, the operating force of the frame side connecting means 12, that is, the first arm 31 is attached to the window frame with respect to the constant operating force of the rivet joint of the heel side connecting means 13 and the constant operating force of the rivet joint of the arm connecting means 14. The adjusting bolt 30 can easily adjust the operating force when rotating about the left-right axis relative to the plate 21 and the operating force when the first arm 31 slides up and down relative to the window frame mounting plate 21. Can do.
Therefore, since it can be easily adjusted by the adjusting bolt 30 so that the inward-turning window 1 operates smoothly at the time of construction, problems after assembly can be eliminated.

その上、枠側連結手段12の作動力を調整ボルト30により調整することができることから、框側連結手段13のリベット継手の作動力及びアーム連結手段14のリベット継手の作動力の規格(設定範囲)を広げることができるため、ステー11単体の組立調整及び出荷時の管理が容易になる。
その上さらに、施工後に内倒し窓1を使用し、摩耗等による経時変化によりステー11の框側連結手段13のリベット継手の作動力及びアーム連結手段14のリベット継手の作動力並びに枠側連結手段12の作動力が変動して内倒し窓1が滑らかに動作しなくなった場合においても、調整ボルト30による調整により内倒し窓1が滑らかに動作する状態に容易に復帰させることができる。
In addition, since the operating force of the frame side connecting means 12 can be adjusted by the adjusting bolt 30, the standards of the operating force of the rivet joint of the heel side connecting means 13 and the operating force of the rivet joint of the arm connecting means 14 (setting range). ) Can be expanded, the assembly adjustment of the stay 11 alone and the management at the time of shipment become easy.
In addition, the inversion window 1 is used after the construction, and the operating force of the rivet joint of the heel side connecting means 13 of the stay 11 and the operating force of the rivet joint of the arm connecting means 14 and the frame side connecting means due to changes over time due to wear or the like. Even when the operating force of 12 is fluctuated and the inward-turning window 1 does not operate smoothly, it is possible to easily return to the state in which the inward-turning window 1 operates smoothly by adjustment with the adjustment bolt 30.

また、第1アーム31の丸孔31A内の筒体26は、左右方向軸まわりの回転が規制された状態で窓枠取付板21に沿って上下方向にスライドするスライド体25と一体化されているため、第1アーム31が左右方向軸まわりに回動しても筒体26は回動しない。
さらに、第1ワッシャ27及び第2ワッシャ28も、筒体26の正六角形状外側面26Aに外嵌しているため、第1アーム31の動きにつられて左右方向軸まわりに回動することがない。
よって、第2ワッシャ28に頭部30Aが押圧される調整ボルト30が、第1アーム31の回動により影響を受けないことから、第1アーム31の回動により調整ボルト30が緩まないため、調整が完了した状態を長期にわたって安定かつ確実に保持することができる。
Further, the cylindrical body 26 in the round hole 31A of the first arm 31 is integrated with a slide body 25 that slides in the vertical direction along the window frame mounting plate 21 in a state in which the rotation around the left-right axis is restricted. Therefore, the cylindrical body 26 does not rotate even if the first arm 31 rotates about the left-right axis.
Further, since the first washer 27 and the second washer 28 are also fitted on the regular hexagonal outer surface 26A of the cylindrical body 26, the first washer 27 and the second washer 28 can be rotated around the left-right axis as the first arm 31 moves. Absent.
Therefore, since the adjustment bolt 30 whose head 30A is pressed against the second washer 28 is not affected by the rotation of the first arm 31, the adjustment bolt 30 is not loosened by the rotation of the first arm 31, The state where the adjustment is completed can be stably and reliably maintained for a long time.

なお、框側連結手段13及びアーム連結手段14についても、リベット継手ではなく調整ボルトにより調整可能とする構成も考えられるが、このような構成では、框側連結手段13及びアーム連結手段14まわりが大きくなることから、ステーを縦枠2Sと縦框3Sとの隙間に組み込むことができなくなる場合があるとともに、調整箇所が増えて調整作業が面倒になることから、却って内倒し窓の施工時間が長くなるとともにコストが増大するため、好ましい構成ではない。
また、3箇所の連結手段12,13,14をいずれもリベット継手とした際の作動力のばらつきの評価により、枠側連結手段12のばらつきが最も大きいことがわかっているため、本発明の構成のように、框側連結手段13及びアーム連結手段14をリベット継手として作動力を一定とし、枠側連結手段12のみを調整ボルト30等により調整可能として作動力を調整する構成が最も効果的かつ実用的なものである。
It should be noted that the heel side connecting means 13 and the arm connecting means 14 can be adjusted not by rivet joints but by adjusting bolts, but in such a configuration, the periphery of the heel side connecting means 13 and the arm connecting means 14 is around. Since it becomes large, the stay may not be able to be incorporated into the gap between the vertical frame 2S and the vertical rod 3S, and the adjustment work becomes troublesome due to an increase in adjustment points. This is not a preferable configuration because the cost increases as the length increases.
Moreover, since it is known from the evaluation of the variation in the operating force when all of the three coupling means 12, 13, and 14 are rivet joints, the variation in the frame side coupling means 12 is the largest. As described above, the configuration in which the operating force is adjusted by using the heel side connecting means 13 and the arm connecting means 14 as a rivet joint so that the operating force is constant and only the frame side connecting means 12 can be adjusted by the adjusting bolt 30 or the like is most effective and It is practical.

次に、内倒し窓1を滑らかに動作させるためのステー11の調整方法について説明する。
図1に示すように、閉位置Aから取手8を下げて小角度傾倒位置Bまで障子3を傾倒させた状態から、操作片17Aを上げて可動ストッパ17を上方へスライドさせることにより、前記のとおり障子3をさらに大角度傾倒位置Cまで内倒した状態となる。
この大角度傾倒位置Cから取手8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4まわりに回動させた際に、前述の図8(b)の説明と同様に、図2の位置Dに示すように前記小角度傾倒位置Bで障子3が保持された状態(図1の小角度傾倒位置B)とならない場合があり、このような場合が、框側連結手段13及びアーム連結手段14の一定の作動力に対して枠側連結手段12の作動力が適切に調整されていない状態であり、このような状態では操作感も悪くなっている。
Next, a method for adjusting the stay 11 for smoothly operating the inward-turning window 1 will be described.
As shown in FIG. 1, from the state where the handle 8 is lowered from the closed position A and the shoji 3 is tilted to the small angle tilt position B, the operating piece 17A is raised and the movable stopper 17 is slid upward to As shown, the shoji 3 is further inwardly tilted to the large-angle tilt position C.
When the shoji 3 is pushed forward (outdoor direction) by holding the handle 8 from the large-angle tilt position C and rotated around the rotation support portion 4, as described above with reference to FIG. As shown in the position D of FIG. 2, the shoji 3 may not be held at the small angle tilt position B (small angle tilt position B of FIG. 1). In addition, the operating force of the frame side connecting means 12 is not properly adjusted with respect to the constant operating force of the arm connecting means 14, and in this state, the operational feeling is also deteriorated.

したがって、内倒し窓1が滑らかに動作しない状態、すなわち大角度傾倒位置Cから取手8を前方に操作しても障子3が小角度傾倒位置Bにならない状態から、調整ボルト30をドライバ等の工具により回転させて、図1に示すように、大角度傾倒位置Cから必ず小角度傾倒位置Bとなるように調整することにより、ステー11の窓枠取付板21を窓枠2の縦枠2Sにねじ止めし障子取付板22を障子3の縦框3Sにねじ止めして組付け作業が完了した後の内倒し窓1に対し、この内倒し窓1が滑らかに動作するように容易に調整することができる。   Therefore, the adjustment bolt 30 is removed from the state where the inward-turning window 1 does not operate smoothly, that is, when the shoji 3 does not reach the small-angle tilt position B even if the handle 8 is operated forward from the large-angle tilt position C. 1 to adjust the window frame mounting plate 21 of the stay 11 to the vertical frame 2S of the window frame 2 by adjusting the large angle tilt position C so as to be always the small angle tilt position B as shown in FIG. The screwed-in shoji mounting plate 22 is screwed to the vertical saddle 3S of the shoji 3 to easily adjust the tilted window 1 so that the tilted window 1 operates smoothly after the assembly work is completed. be able to.

以上の説明においては、枠側連結手段12を、窓枠取付板21に形成された長孔21B、第1アーム31の一端に形成された左右方向の丸孔31A、スライド体25、筒体26、第1ワッシャ27、第2ワッシャ28、板ナット29及び調整ボルト30により構成する場合を示したが、枠側連結手段12は、長孔21B、丸孔31A、スライド体25、並びに、第1アーム31に直接又はワッシャを介して頭部が当止され、スライド体25の螺孔又はスライド体25に当止される板ナット29に螺合した左右方向の調整ボルト30を少なくとも備えて構成されるものであればよい。   In the above description, the frame-side connecting means 12 includes the long hole 21 </ b> B formed in the window frame mounting plate 21, the left and right round holes 31 </ b> A formed at one end of the first arm 31, the slide body 25, and the cylinder body 26. Although the case where the first washer 27, the second washer 28, the plate nut 29 and the adjustment bolt 30 are used is shown, the frame side connecting means 12 includes the long hole 21B, the round hole 31A, the slide body 25, and the first The head is held against the arm 31 directly or via a washer, and is provided with at least a left-right adjustment bolt 30 screwed into a screw hole of the slide body 25 or a plate nut 29 held against the slide body 25. Anything is acceptable.
