Description

本考案は、温室内の環境を良好に保持するため妻側に設置されている換気窓の開閉をスムーズに操作できる温室の換気窓開閉装置に関する。  The present invention relates to a ventilation window opening / closing device for a greenhouse that can smoothly open and close the ventilation window installed on the wife side in order to maintain a favorable environment in the greenhouse.

植物育成のための温室に張架される温室カーテンは、空気注入して膨隆した二枚一対のフィルムからなるものが汎用されていて、そのカーテンからの温熱によって温室内が適温となるように各種装置を付設して温度調節がなされているが、冬場と夏場による外気温の差は当然として同じ季節であっても晴天と雨天、昼と夜には大きな温度差や湿度の変化も多様であり、植物育成のための環境維持には細心の注意がはらわれていなければならず、このため温室外壁を構成するところのカーテンの開閉操作によって空気流通を図るだけでは必ずしも十分とはいえないことが知られている。  Greenhouse curtains stretched over a greenhouse for plant cultivation are generally made of a pair of two films that are bulged by air injection, and various types are used so that the temperature inside the greenhouse can be adjusted appropriately by the heat from the curtains. Although the temperature is adjusted by attaching a device, the difference in outside air temperature between winter and summer is natural, even in the same season, there are various temperature differences and humidity changes in clear weather and rainy weather, and day and night. Careful attention must be paid to maintaining the environment for growing plants. Therefore, it is not always sufficient to aim at air circulation by opening and closing the curtains that make up the outer wall of the greenhouse. Are known.

ちなみにカーテン開閉個所としての温室側面、天窓部などの開閉に従来装置として開示されている技術が多数存在するとはいえ、それらの開閉装置としての機能を発揮するためには温室全体の構成にゆだねるところが少なからずあり、それゆえ装置に多大な労力と費用がかかるという問題があり、そのために温室カーテンの開閉装置とは別に温室に固定した妻側等に換気窓を設置し、その窓からの通風加減によって程よい換気調節をすることで一層の環境整備がなされていることは膨大な費用を節しつつその目的を達成するうえからも適切有効な手段とみることができる（例えば特許文献１〜３参照）。  By the way, although there are many technologies that have been disclosed as conventional devices for opening and closing the side of the greenhouse as the curtain opening and closing location, the skylight, etc., in order to exert the function as those opening and closing devices, it depends on the configuration of the entire greenhouse. There is a considerable amount of labor and cost for the equipment. Therefore, a ventilation window is installed on the wife side fixed to the greenhouse separately from the opening and closing device of the greenhouse curtain, and the ventilation from the window is adjusted. It can be seen as appropriate effective means for achieving the purpose while saving enormous cost that further environmental improvement is made by appropriately adjusting the ventilation according to (see, for example, Patent Documents 1 to 3). ).

すなわち換気窓によって温室上部からの空気流通、適度な排気が行われることはモーター駆動により膨隆するカーテンの温熱が温室上部に集中する不利を解消するための手段として好ましく、また妻側に大掛かりでない換気窓を設置することは雨水等の流入防止は当然として防虫網を取り付けることで害虫の侵入防止を図ることができるというメリットもある。  In other words, air circulation from the upper part of the greenhouse through the ventilation window and appropriate exhaust are preferable as a means for eliminating the disadvantage that the heat of the curtain that is swollen by the motor drive concentrates on the upper part of the greenhouse, and ventilation that is not excessive on the wife side. The installation of windows has the merit of preventing the invasion of pests by attaching an insect net as a matter of course to prevent the inflow of rainwater and the like.

上記の文献に示された従来技術のうち文献１は高い位置に設置された片開き窓に関するものであり、開閉ロープを操作すると窓枠と駆動枠体間に連結してある支持棒が上下動及び回動して窓の開閉をすることを特徴としているが、この支持棒はいわば突っ張り棒のような働きをするものであるから窓を全開するには適するが、途中での位置決めはラッチ機能に依るためラッチの動きに齟齬を生じると停止位置が不安定となる懸念がある。  Among the prior arts shown in the above-mentioned documents, Document 1 relates to a single-sided window installed at a high position. When the open / close rope is operated, the support rod connected between the window frame and the drive frame body moves up and down. It is characterized by rotating and opening and closing the window, but this support bar works like a tension bar, so it is suitable for fully opening the window, but positioning in the middle is a latch function Therefore, there is a concern that the stop position may become unstable if wrinkles occur in the movement of the latch.

しかして文献２に開示されたものは、駆動車と従動車間にエンドレスチェーンを掛装し、該エンドレスチェーンの動きに連動するプッシュロッドが換気窓を押し上げ引き下げることを特徴とした技術であるが、駆動源には電動モーター又は油圧モーターを想定しており（明細書の［００４２］参照）、当然ながらそれらを設置するためにはスペースの確保及び装置等に別途費用を要することは否めない。またチェーンは長期使用中に一部でも駆動車又は従動車から外れると本来の働きをすることができず、ひいては窓の開閉に支障を生じるという問題がある。  Therefore, what is disclosed in Document 2 is a technique characterized in that an endless chain is hung between a driving vehicle and a driven vehicle, and a push rod interlocked with the movement of the endless chain pushes the ventilation window up and down. As the drive source, an electric motor or a hydraulic motor is assumed (see [0042] in the specification). Naturally, it is undeniable that a space is required and a device or the like is separately required to install them. Further, there is a problem that if the chain is partly removed from the driving vehicle or the driven vehicle during long-term use, the chain cannot perform its original function, and consequently the opening and closing of the window is hindered.

文献３は駆動機構をいたずらに大型化させず、コストの低減化を可能にすることを意図した技術である。そのために駆動機構が枠体あるいは近傍部に保持される支持体と、この支持体に基端ウオームホイールが枢支されながらこの支持体の外に突出する先端アーム部を遮蔽体（窓）に連結させる駆動アーム部材と、この駆動アーム部材の基端ウオームホイール部に先端ネジ部を噛合させながら支持体に保持される駆動軸とを有し、この駆動軸が支持体の外に突出する基端入力部は外力の入力で回動されて駆動アーム部材の基端ウオームホイール部を回動し、この基端ウオーム部の回動で駆動アーム部材が先端アーム部を揺動させて遮蔽体を動かし、遮蔽体が妻面開口を開閉することを特徴としている。  Document 3 is a technique intended to enable cost reduction without unnecessarily increasing the size of the drive mechanism. For this purpose, a support body in which the drive mechanism is held at the frame body or in the vicinity thereof, and a distal arm part that protrudes outside the support body while the base end worm wheel is pivotally supported by this support body are connected to the shielding body (window). A drive arm member to be driven, and a drive shaft held by the support body with the distal end threaded portion engaged with the proximal end worm wheel portion of the drive arm member, and a base end projecting out of the support body The input portion is rotated by the input of an external force to rotate the proximal end worm wheel portion of the drive arm member, and the rotation of the proximal end worm portion causes the drive arm member to swing the distal end arm portion to move the shield. The shield is characterized by opening and closing the opening on the wife surface.

上記構成とした文献３では駆動機構を保持する支持体が枠体の中央部に設置されていて牽引ロープを操作すると駆動アーム部材の動きでリンク部材等が作動し窓の開閉が行われるというものであるが、駆動機構は窓の中央に位置するため例えば妻面側開閉窓の直下に出入口があると牽引ロープがその部分まで垂れ下がることになるといった不具合が起きる。また窓の中央に駆動機構が存在することでその分空気流通が阻害される恐れもある。  In Document 3 configured as described above, the support body that holds the drive mechanism is installed at the center of the frame, and when the tow rope is operated, the link member and the like are operated by the movement of the drive arm member, and the window is opened and closed. However, since the drive mechanism is located at the center of the window, for example, if there is an entrance / exit directly under the opening / closing window on the side of the wife, there is a problem that the tow rope hangs down to that part. In addition, the presence of a drive mechanism in the center of the window may hinder air flow.

本考案は上記した従来技術に鑑み、その課題解決のために操作が簡単で換気窓の開閉がスムーズになされ、開閉位置も確実迅速に設定でき強風にもガタを生ずることなく堅牢性を発揮するとともに複雑な構成とならないためコストを節して安価に提供できる換気窓開閉装置を提供することを目的としている。  In view of the above-described prior art, the present invention is easy to solve the problem, and the opening and closing of the ventilation window is smoothly performed, the opening and closing position can be set quickly and reliably, and robustness is exhibited without causing backlash even in strong winds. In addition, an object of the present invention is to provide a ventilation window opening and closing device that can be provided at low cost because it does not have a complicated configuration.

上記の目的を達成するための手段として本考案は、温室の妻側に設置した換気窓が、ロープを操作すると窓枠の一側端に位置する駆動手段を介して回転軸が可動するのに伴い、回転軸に固着したＬ字部材に基部を枢着し且つ先端部を窓枠の縦材に枢着した湾曲アームの押し引きによって開閉し、
前記駆動手段はケーシング内にブレーキ機能を有する伝動部と、大小の駆動及び被動ギアを噛合してなる減速機構を備え、ロープを操作して湾曲アームを所定位置で停止するとブレーキが働いて位置決めされた窓の開口状態が保持されることを主旨とする。As a means for achieving the above object, the present invention provides a ventilation window installed on the wife side of a greenhouse. When the rope is operated, the rotating shaft can be moved through a driving means located at one end of the window frame. Along with this, the base is pivotally attached to the L-shaped member fixed to the rotating shaft, and the distal end is opened and closed by pushing and pulling the curved arm pivotally attached to the vertical member of the window frame,
The drive means includes a transmission portion having a brake function in the casing and a speed reduction mechanism that meshes the large and small drive and driven gears. When the rope is operated and the curved arm is stopped at a predetermined position, the brake is operated and positioned. The main purpose is to maintain the open state of the window.

Ｌ字部材が回転軸とともに後方下部に傾倒して湾曲アーム後端が回転軸の後部下方に位置すると窓が閉鎖し、Ｌ字部材が回転軸の動きに伴い前傾して湾曲アーム先端が上方極限位置で停止すると窓が全開し、夫々の位置で固定保持されることを特徴とする。  When the L-shaped member tilts to the rear lower part together with the rotating shaft and the rear end of the curved arm is positioned below the rear portion of the rotating shaft, the window is closed, and the L-shaped member tilts forward with the movement of the rotating shaft and the leading end of the curved arm is raised. When it stops at the extreme position, the window is fully opened and is fixedly held at each position.

伝動部が、滑車の回転に連動する入力軸と、駆動ギアを回転させる出力軸との間にバネ部材を跨設した筒状部を備え、バネ部材が縮径すると出力軸が回転し、拡径するとブレーキ機能が発揮されて出力軸に回転伝達がされないことを特徴とする。  The transmission portion includes a cylindrical portion having a spring member straddled between an input shaft that interlocks with the rotation of the pulley and an output shaft that rotates the drive gear. When the diameter of the spring member is reduced, the output shaft rotates and expands. When the diameter is increased, the brake function is exhibited, and the rotation is not transmitted to the output shaft.

前記減速機構における駆動ギアが小歯車であり、被動ギアが大歯車であることを特徴とする。  The drive gear in the speed reduction mechanism is a small gear, and the driven gear is a large gear.

Ｌ字部材に鉤形ストッパーを固着し、該鉤形ストッパーの鉤片が、窓全開時に湾曲アームを圧接することを特徴とする。  A hook-shaped stopper is fixed to the L-shaped member, and the hook-shaped piece of the hook-shaped stopper presses the curved arm when the window is fully opened.

前記回転軸が、断面方形の角形パイプからなることを特徴とする。  The rotating shaft is a square pipe having a square cross section.

湾曲アームの先端部が直接窓枠の縦材に枢着してあり、ロープを操作すると窓開閉時に湾曲アームが放物線を描いて所定の動きをすることにより確実迅速に窓の開閉を行うことができる。  The tip of the curved arm is pivotally attached directly to the vertical member of the window frame, and when the rope is operated, the curved arm draws a parabola and opens and closes the window quickly and reliably when opening and closing the window. it can.

駆動手段が窓枠の一側端に位置するため換気窓の正面中央には通風を阻害する遮蔽物がなく、室内の換気が所望する状態に保たれて植物育成環境を最適な状況とする。  Since the driving means is located at one side edge of the window frame, there is no shielding object in the center of the front of the ventilation window, and the indoor ventilation is maintained in a desired state, so that the plant growing environment is in an optimum state.

駆動手段がブレーキ機能を有する伝動部と減速機構を備えているため回転軸がスムーズに作動し、開閉操作だけでなく停止したときにブレーキが働いて換気窓の開口位置を不動状とすることができる。  Since the drive means is equipped with a transmission part having a brake function and a speed reduction mechanism, the rotating shaft operates smoothly, and the brake works when not only opening and closing operation, but also makes the opening position of the ventilation window immovable. it can.

図面を参照して本考案の形態を説明すると、図１は温室の妻側に設置した換気窓を室内側から見た図であり、窓１を開閉するための回転軸１０が窓枠２の長手方向に沿って横架されている。回転軸１０の一方（図では左側）は窓固定枠３に上下部を固定した支柱４に取り付けた軸受け５に回動自在に枢支され、他方（右側）が他方の支柱４に固定されたケーシングＡに枢支され、ケーシングＡに近接すると滑車１１にロープ１２が掛装されている。前記回転軸１０にはネジ固定によりＬ字部材８が取り付けられ、このＬ字部材に基部を枢着した湾曲アーム７の先端部が窓枠２の縦材６に枢着されていて、湾曲アーム７の押し引きにより窓１が開閉する。なお回転軸１０は、Ｌ字部材８等を取り付けるのを容易にするためにも角パイプとすることが好ましい。  The embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a view of a ventilation window installed on the wife side of a greenhouse as viewed from the indoor side, and a rotating shaft 10 for opening and closing the window 1 is the window frame 2. It is laid horizontally along the longitudinal direction. One of the rotating shafts 10 (the left side in the figure) is pivotally supported by a bearing 5 attached to a column 4 whose upper and lower portions are fixed to the window fixing frame 3, and the other (right side) is fixed to the other column 4. A rope 12 is hung on the pulley 11 when it is pivotally supported by the casing A and close to the casing A. An L-shaped member 8 is attached to the rotary shaft 10 by screw fixing, and a distal end portion of a bending arm 7 pivotally attached to the L-shaped member is pivotally attached to the vertical member 6 of the window frame 2. The window 1 is opened and closed by pushing and pulling 7. The rotating shaft 10 is preferably a square pipe in order to make it easy to attach the L-shaped member 8 or the like.

ケーシングＡには伝動部２１と、駆動及び被動ギアからなる減速機構２２で構成される駆動手段２０が内蔵され、該駆動手段２０が前記ロープ１２を操作することで作動するのに連動して回転軸１０が回転する仕組みであり、滑車１１の中心部はケーシングＡ内の伝動部２１と同軸上にある。  The casing A includes a drive unit 20 including a transmission unit 21 and a speed reduction mechanism 22 including a drive and driven gear. The drive unit 20 rotates in conjunction with the operation by operating the rope 12. The shaft 10 rotates, and the central portion of the pulley 11 is coaxial with the transmission portion 21 in the casing A.

図２は湾曲アーム７の押し引きによる窓１の開閉状態を示したもので、実線が窓１の閉鎖状態、仮想線が開口状態を示している。ロープ１２の閉じる側（図では左側）を下方に引っ張るとケーシングＡ内の駆動・被動ギアの回転により回転軸１０が右方向に回転しＬ字部材８が右回転して先端部が回転軸１０の下部に移動し、同時にへ字形とした湾曲アーム７後方が回転軸１０を囲うような形でその後端部がＬ字部材８の先端部と重なり合う。このとき湾曲アーム７の先端部が窓枠２の縦材６を引っ張るため窓１は閉鎖され、しかも湾曲アーム７の後端部が回転軸１０下方に移動して回転軸をはさみ先端部と枢着個所に支店のずれを生じさせるためロープ１２を開方向に操作しない限り窓１が開口することはなく、窓は固定枠３にぴったりと密着してその閉鎖状態は確固として保たれ、ストッパーを設けなくても強風・振動等によるガタツキなどは生じない。  FIG. 2 shows the opened / closed state of the window 1 by pushing and pulling the bending arm 7, where the solid line indicates the closed state of the window 1 and the imaginary line indicates the opened state. When the side on which the rope 12 is closed (the left side in the figure) is pulled downward, the rotation shaft 10 rotates to the right due to the rotation of the driving / driven gear in the casing A, the L-shaped member 8 rotates to the right, and the tip portion rotates to the rotation shaft 10. At the same time, the rear end portion of the bent arm 7 overlapped with the distal end portion of the L-shaped member 8 so that the rear side of the curved arm 7 which is shaped like a letter surrounds the rotary shaft 10. At this time, the distal end of the curved arm 7 pulls the vertical member 6 of the window frame 2, so that the window 1 is closed, and the rear end of the curved arm 7 moves below the rotating shaft 10 to sandwich the rotating shaft and pivot with the distal end. The window 1 will not open unless the rope 12 is operated in the opening direction in order to cause the branch to shift at the landing point. The window closely contacts the fixed frame 3 and the closed state is firmly maintained, and the stopper is provided. Even if it is not provided, there will be no rattling caused by strong winds or vibrations.

そして上記と逆にロープ１２の開く側（図では右側）を下方に引くと、回転軸１０が左回転して回転軸下方にあるＬ字部材８が反時計方向に動き、その先端部が大きく旋回して湾曲アーム７を押し上げるので湾曲アーム７先端部が窓枠２の縦材６を圧接し窓１が開口される。Ｌ字部材８が大きく前傾して水平状態に近い位置で停止すると湾曲アーム７先端部が上昇極限位置となるため押し上げられた窓１が全開状態となる。  When the rope 12 opening side (the right side in the figure) is pulled downward, the rotation shaft 10 rotates counterclockwise, and the L-shaped member 8 below the rotation shaft moves counterclockwise, and the tip portion is large. Since the curved arm 7 is swung up and the curved arm 7 is pushed up, the distal end of the curved arm 7 presses the vertical member 6 of the window frame 2 and the window 1 is opened. When the L-shaped member 8 is largely tilted forward and stopped at a position close to the horizontal state, the distal end of the bending arm 7 is in the ascending extreme position, so that the pushed-up window 1 is fully opened.

図３及び図４は窓の閉鎖時及び全開時における湾曲アーム７の動きをしめすもので、Ｌ字部材８には鉤形ストッパー９の基部をネジ止めしてあり、鉤形ストッパー９はＬ字部材８と同じ動きをする。窓閉鎖時にはＬ字部材８が前記したように回転軸１０の下方に位置するため、固定してある鉤形ストッパー９は図３のように下垂状態となっていて湾曲アーム７とは離れた位置にある。  3 and 4 show the movement of the curved arm 7 when the window is closed and fully opened. The base of the hook-shaped stopper 9 is screwed to the L-shaped member 8, and the hook-shaped stopper 9 is L-shaped. The same movement as the member 8 is performed. When the window is closed, the L-shaped member 8 is positioned below the rotary shaft 10 as described above, so that the fixed hook-shaped stopper 9 is in a suspended state as shown in FIG. It is in.

回転軸１０が回転してＬ字部材８とともに湾曲アーム７が前方に傾動して窓が全開すると、Ｌ字部材８に基部を固着してある鉤形ストッパー９の先端鉤片９ａが湾曲アーム７の基部をず４のように圧接する。したがって湾曲アーム７は回転軸１０が可動しない限り鉤形ストッパー９によりその動きは抑止され、窓の縦材は湾曲アーム７によって押圧された状態が保持され、全開した窓は微動だにすることがなく風圧等を受けても十分にその開口状態は保持される。  When the rotating shaft 10 is rotated and the curved arm 7 is tilted forward together with the L-shaped member 8 so that the window is fully opened, the distal end hook piece 9a of the hook-shaped stopper 9 whose base is fixed to the L-shaped member 8 is bent. Press the base of 4 as shown in Figure 4. Therefore, the movement of the curved arm 7 is suppressed by the hook-shaped stopper 9 as long as the rotary shaft 10 is not movable, the vertical member of the window is kept pressed by the curved arm 7, and the fully opened window is finely moved. Even if it receives wind pressure or the like, the opening state is sufficiently maintained.

図５は前記ケーシングＡ内の駆動手段２０を示すもので、伝動部２１は滑車側の入力軸から駆動軸側の出力軸に回転を伝達するだけでなく、ブレーキ機能も有している。そして伝動部本体２１ａ内の軸部に連なる小歯車からなる駆動ギア２３が回転をするのに伴って大歯車からなる被動ギア２４が回転し、被動ギア２４に端部を固定してある回転軸１０が回転するもので、駆動ギア２３と被動ギア２４の減速比は１対２〜５が好ましく、こうすることによって回転トルクが数倍となり、伝動部２１のブレーキの動きにも若干の遊びが生じて被動ギア２４と同軸上の回転軸１０が無理なく回転する。  FIG. 5 shows the drive means 20 in the casing A. The transmission portion 21 not only transmits rotation from the pulley-side input shaft to the drive shaft-side output shaft, but also has a brake function. Then, as the drive gear 23 composed of a small gear connected to the shaft portion in the transmission unit main body 21a rotates, the driven gear 24 composed of a large gear rotates, and the rotating shaft having the end fixed to the driven gear 24 is rotated. 10 is rotating, and the reduction ratio of the drive gear 23 and the driven gear 24 is preferably 1 to 2-5. By doing this, the rotational torque is increased several times, and there is also some play in the movement of the brake of the transmission portion 21. As a result, the rotation shaft 10 coaxial with the driven gear 24 rotates without difficulty.

伝動部２１は特に目新しい構成ではなく、従来周知のバネ部材と入出力軸の組み合わせからなるものを用いることができる。すなわち図６で示すように、前記本体２１ａに内設した筒状体２５内面に滑車側の入力軸２６と、被動ギア側の出力軸２７の周面間にバネ部材２８を取り付けた構成であって、前記ロープ１２を操作して滑車１１が回転すると入出力軸２６、２７が正・逆回転し、バネ部材２８が縮径して筒状体２５内面との間に遊びが生じるため入力側からの動きが出力側に及んで駆動ギア２３が回転するが、滑車１２の動きを止めるとバネ部材２８が拡径して筒状体２５の内面を圧接するためその動きが止まり、このため駆動ギア２３は作動せず回転軸１０の逆回は阻止され、したがって例えば窓が半開き状態にあるとブレーキ機能でその位置が確保される。  The transmission unit 21 is not particularly novel, and a conventionally known combination of a spring member and an input / output shaft can be used. That is, as shown in FIG. 6, a spring member 28 is attached between the peripheral surfaces of the pulley-side input shaft 26 and the driven gear-side output shaft 27 on the inner surface of the cylindrical body 25 provided in the main body 21a. When the pulley 11 is rotated by operating the rope 12, the input / output shafts 26 and 27 are rotated in the forward and reverse directions, the spring member 28 is reduced in diameter, and play is generated between the inner surface of the cylindrical body 25 and the input side. However, when the pulley 12 stops moving, the spring member 28 expands in diameter and presses against the inner surface of the cylindrical body 25, so that the movement stops. The gear 23 is not actuated and the reverse rotation of the rotary shaft 10 is prevented. Therefore, for example, when the window is in a half-open state, the position is secured by the brake function.

前記入力軸２６と出力軸２７には早退する膨隆内端部に夫々弧状の介入片２６・２７を突設してあり、入力軸２６の介入片２６が出力軸２７の内端部に、また出力軸２７の介入片が入力軸２６の内端部に接する構成であり、バネ部材２８の両端を内向きに屈曲して形成した鉤部２８の各内面間に入力軸２６の介入片２６が臨み、鉤部２８の各外周面間に出力軸２７の介入片２７が臨んでいる。そして入力軸２６が回転すると介入片２６の側端面のいずれかが鉤部２８のいずれかの内側面に当接するためバネ部材２８を巻き締め、バネ部材２８は縮径して筒状体２５内で回転する。バネ部材２８が回転すると鉤部２８が出力軸側の介入片２７の側端面に当接して出力軸２７が入力軸２６と同方向に回転するので減速機構２２を介して回転軸１０が回転し、それに伴い湾曲アーム７が可動して換気窓を開閉する。  The input shaft 26 and the output shaft 27 are respectively provided with arc-shaped intervention pieces 26 and 27 at the bulging inner end portions that retreat quickly, and the intervention pieces 26 of the input shaft 26 are formed on the inner end portion of the output shaft 27 and The intervention piece of the output shaft 27 is in contact with the inner end portion of the input shaft 26, and the intervention piece 26 of the input shaft 26 is interposed between the inner surfaces of the flange portion 28 formed by bending both ends of the spring member 28 inward. The intervention piece 27 of the output shaft 27 faces between the outer peripheral surfaces of the flange portion 28. When the input shaft 26 rotates, any one of the side end surfaces of the intervention piece 26 comes into contact with any inner surface of the flange portion 28, so that the spring member 28 is wound up. Rotate with. When the spring member 28 rotates, the collar portion 28 abuts on the side end surface of the intervention piece 27 on the output shaft side, and the output shaft 27 rotates in the same direction as the input shaft 26, so that the rotating shaft 10 rotates via the speed reduction mechanism 22. Accordingly, the bending arm 7 moves to open and close the ventilation window.

窓の開閉を所定位置で停止したときになおも出力軸２７に回転力が加わった場合は、出力軸介入片２７の側端面のいずれかがバネ部材２８の鉤部２８のいずれかの外側面に当接して押圧する。このためバネ部材２８は巻き戻されて拡径し、その外面が筒状体２５の内面を圧接するので出力軸２７の回転は阻止されて出力軸に加わった回転力は入力軸には伝達されない。なお、このブレーキの構成は従来周知の手法であるから格別目新しいものではないが、このようなブレーキ機能を設けることによって換気窓の開閉操作が確実容易となる。  If the rotational force is still applied to the output shaft 27 when the opening / closing of the window is stopped at a predetermined position, any one of the side end surfaces of the output shaft intervention piece 27 is either the outer surface of the flange portion 28 of the spring member 28. Press against. For this reason, the spring member 28 is rewound and expanded in diameter, and the outer surface presses the inner surface of the cylindrical body 25, so that the rotation of the output shaft 27 is prevented and the rotational force applied to the output shaft is not transmitted to the input shaft. . Note that the configuration of the brake is not particularly new because it is a well-known technique, but the opening and closing operation of the ventilation window is surely facilitated by providing such a brake function.
