Description

本発明は、引違い建具用閉速度減少装置に関し、より詳細には、障子の閉操作時に所定の区間で速度を減少させると共に、障子が容易に閉まるようにした引違い建具用閉速度減少装置に関する。 The present invention relates to a closing speed reducing device for sliding fittings. More specifically, the present invention is a closing speed reducing device for sliding fittings in which the speed is reduced in a predetermined section when the shoji is closed and the shoji is easily closed. Regarding.

一般に、マンションや住宅の窓又は居間などの開口部には、障子を選択的に開閉できる引違い建具が設置される。 Generally, sliding fittings that can selectively open and close shoji screens are installed in openings such as windows or living rooms of condominiums and houses.

このような引違い建具は、障子の閉操作時に使用者の不注意により必要以上の力が加わる場合がある。この場合、強い力で急速に閉まる障子は、慣性によって窓枠に衝撃を加えることになり、これにより、騒音が発生したり、ひどい場合は建具が破損したりする恐れがある。 Such a sliding fitting may apply more force than necessary due to the carelessness of the user when closing the shoji. In this case, the shoji that closes rapidly with a strong force will give an impact to the window frame due to inertia, which may generate noise or, in severe cases, damage the fittings.

これを防止できるように、従来に特許文献１（公開日：２０１０．０１．０６）として「引違い建具の安全閉鎖装置」が先に出願されている。 In order to prevent this, Patent Document 1 (publication date: 2010.01.06) has previously filed a "safety closing device for sliding fittings".

具体的には、従来の引違い建具の安全閉鎖装置は、障子に係止部材が設置され、窓枠には、前記障子の閉鎖時に係止部材が係止されて障子の閉鎖速度を減少させることができるようにロッドの先端にフックが備えられたダンパーが設置される。この場合、ダンパーの一側には引張りバネが連結されて、ダンパーの圧縮力及び引張りバネの弾性復元力によって障子が急激に閉まらずにゆっくりと閉まるようにしたものである。 Specifically, in the conventional safety closing device for sliding fittings, a locking member is installed on the shoji, and the locking member is locked on the window frame when the shoji is closed to reduce the closing speed of the shoji. A damper with a hook at the tip of the rod is installed so that it can be done. In this case, a tension spring is connected to one side of the damper so that the shoji does not close suddenly but slowly closes due to the compressive force of the damper and the elastic restoring force of the tension spring.

この場合、前記のような構成の安全閉鎖装置は、ダンパーの圧縮力及び引張りバネの弾性復元力が同時に作用するようになるもので、前記引張りバネの弾性復元力をダンパーの圧縮力が相殺させるようになる。 In this case, in the safety closing device having the above configuration, the compressive force of the damper and the elastic restoring force of the tension spring act at the same time, and the compressive force of the damper cancels the elastic restoring force of the tension spring. It will be like.

すなわち、前記障子を少ない力で容易に閉まるようにするためには、ある程度の弾性復元力が必要である。 That is, a certain amount of elastic restoring force is required in order to easily close the shoji with a small force.

しかし、前記引張りバネの弾性復元力は、ダンパーを圧縮させるのに共に使用されることによって、実際に前記障子を容易に閉まるように押し付ける力（弾性復元力）が足りなくなり得るという構造的な問題点がある。 However, the elastic restoring force of the tension spring may be used together to compress the damper, so that the force (elastic restoring force) that actually presses the shoji so as to be easily closed may be insufficient, which is a structural problem. There is a point.

大韓民国公開特許第１０－２０１０－０００１７７６号Republic of Korea Published Patent No. 10-2010-0001776

本発明は、上述した問題点を解決するために案出されたもので、障子の閉操作時に所定の区間でダンパーの圧縮力及び引張りバネの弾性復元力が順次作動するように構成することによって、障子が慣性によって速い速度で強く閉まることを防止すると共に、少ない力で障子が容易に閉められるようにした引違い建具用閉速度減少装置を提供することにその目的がある。 The present invention has been devised to solve the above-mentioned problems, and by configuring the damper so as to sequentially operate the compressive force of the damper and the elastic restoring force of the tension spring in a predetermined section when the shoji is closed. It is an object of the present invention to provide a closing speed reducing device for sliding fittings, which prevents the shoji from closing strongly at a high speed due to inertia and allows the shoji to be easily closed with a small force.

上述したような目的を具現するための本発明の引違い建具用閉速度減少装置は、窓枠に固定設置され、係止突起が突出形成される係止部と；前記窓枠にスライド開閉可能に結合される障子に設置され、内部に収納空間が設けられる本体部と；前記本体部内に設置され、前記障子の閉操作時に、ダンパーロッドの先端に備えられた第１フックが前記係止突起に係止されてダンパーシリンダを圧縮させながら前記障子の閉速度を減少させる減速部と；前記障子の閉操作時に、前記減速部の作動後、所定の時間差を置いて作動できるように前記本体部の内部に一端が固定され、他端に第２フックが設置される引張りバネを含み、前記第２フックが前記係止突起に係止される瞬間、引っ張られていた引張りバネの弾性復元力によって前記障子を閉まる方向に押して移動させる弾性駆動部と；を含む。 The closing speed reducing device for sliding fittings of the present invention for realizing the above-mentioned object is fixedly installed on a window frame and has a locking portion in which a locking protrusion is formed so as to be able to slide open and close on the window frame. A first hook installed in the main body and provided with a storage space inside the shoji, and a first hook provided at the tip of the damper rod when the shoji is closed. A deceleration unit that is locked to and compresses the damper cylinder to reduce the closing speed of the shoji; Includes a tension spring with one end fixed inside and a second hook installed at the other end, by the elastic restoring force of the tension spring being pulled at the moment the second hook is locked to the locking projection. Includes an elastic drive unit that pushes and moves the shoji in the closing direction;

以上のような構成による本発明は、障子の閉操作時に、ダンパーの圧縮力を用いて、障子が慣性によって速い速度で強く閉まることを防止することができ、併せて、順次作動する引張りバネの弾性復元力を用いて、少ない力で障子を容易に閉めることができる利点がある。 According to the present invention having the above configuration, it is possible to prevent the shoji from being strongly closed at a high speed due to inertia by using the compressive force of the damper when the shoji is closed. There is an advantage that the shoji can be easily closed with a small force by using the elastic restoring force.

図１は、本発明に係る引違い建具用閉速度減少装置の室内側立面図であり、図２は、閉速度減少装置の斜視図であり、図３は、閉速度減少装置の分解斜視図である。 FIG. 1 is an indoor elevation view of the closing speed reducing device for a sliding fitting according to the present invention, FIG. 2 is a perspective view of the closing speed reducing device, and FIG. 3 is an exploded perspective view of the closing speed reducing device. It is a figure.

図１及び図２を参照すると、本発明の好ましい一実施例に係る引違い建具用閉速度減少装置１００は、係止部１１０、本体部１２０、減速部１３０、及び弾性駆動部１４０を含む。 Referring to FIGS. 1 and 2, the closing speed reducing device 100 for a sliding fitting according to a preferred embodiment of the present invention includes a locking portion 110, a main body portion 120, a deceleration portion 130, and an elastic drive portion 140.

このような本発明の構成について具体的に説明すると、次の通りである。 A specific description of such a configuration of the present invention is as follows.

係止部１１０は、窓枠１０の上部の所定の地点に固定設置され、下方に係止突起１１１が突出形成される。前記係止突起１１１には、後述する減速部１３０の第１フック１３５及び弾性駆動部１４０の第２フック１４３が順次係止固定される。 The locking portion 110 is fixedly installed at a predetermined position on the upper part of the window frame 10, and the locking projection 111 is formed so as to protrude downward. The first hook 135 of the deceleration unit 130 and the second hook 143 of the elastic drive unit 140, which will be described later, are sequentially locked and fixed to the locking projection 111.

この場合、本発明では、係止部１１０を含む閉速度減少装置１００が窓枠１０の上部に設置された場合の一例を挙げて示したが、もちろん、これに限定されず、窓枠１０の下部に形成されてもよい。 In this case, the present invention has shown an example of a case where the closing speed reducing device 100 including the locking portion 110 is installed on the upper part of the window frame 10, but of course, the present invention is not limited to this, and the window frame 10 is not limited to this. It may be formed at the bottom.

しかし、使用者の不注意や子供の好奇心による事故が発生する恐れがあるので、前記閉速度減少装置１００は、使用者の手が届かない窓枠１０の上部に設置されることが好ましい。 However, since there is a risk of accidents due to the carelessness of the user or the curiosity of the child, it is preferable that the closing speed reducing device 100 is installed on the upper part of the window frame 10 which is out of the reach of the user.

本体部１２０は、閉速度減少装置１００の主なボディーをなすもので、窓枠１０にスライド開閉可能に結合される障子２０に設置され、内部には収納空間が設けられる。 The main body 120 forms the main body of the closing speed reducing device 100, and is installed on a shoji 20 that is slidably connected to the window frame 10 so as to be openable and closable, and a storage space is provided inside.

図３を参照すると、前記本体部１２０内には、障子２０の開閉方向に沿って第１ガイド溝１２１と第２ガイド溝１２３が並んで形成され、前記減速部１３０と弾性駆動部１４０が時間差を置いて順次作動できるように互いに異なる長さで形成される。このような第１及び第２ガイド溝１２１，１２３の具体的な構成は、後述する減速部１３０及び弾性駆動部１４０と共に説明する。 Referring to FIG. 3, a first guide groove 121 and a second guide groove 123 are formed side by side in the main body portion 120 along the opening / closing direction of the shoji 20, and the deceleration portion 130 and the elastic drive portion 140 have a time difference. They are formed in different lengths so that they can be placed and operated sequentially. The specific configuration of the first and second guide grooves 121 and 123 will be described together with the deceleration unit 130 and the elastic drive unit 140 described later.

減速部１３０は、本体部１２０内の収納空間に設置されるものであって、障子２０の閉操作時に一定の区間、すなわち、減速部１３０の第１フック１３５が係止部１１０の係止突起１１１に係止され始める地点から作動することで、障子２０が慣性によって強く閉まることを防止する。 The deceleration unit 130 is installed in a storage space inside the main body unit 120, and a certain section during the closing operation of the shoji 20, that is, the first hook 135 of the deceleration unit 130 is a locking projection of the locking portion 110. By operating from the point where it starts to be locked to 111, the shoji 20 is prevented from being strongly closed by inertia.

図４を参照して具体的に説明すると、前記減速部１３０は、本体部１２０の収納空間に設置されるダンパーシリンダ１３１と、ダンパーシリンダ１３１内に障子２０の開閉方向に沿って前・後進可能に結合されるダンパーロッド１３３と、ダンパーロッド１３３の先端に所定角度回動可能にヒンジ結合されると共に、第１ガイド溝１２１にスライド可能に結合される第１フック１３５とを含むことで、障子２０の閉操作時に前記係止部１１０の係止突起１１１に第１フック１３５の係止溝１３５ａが係止されながら、前進したダンパーロッド１３３を後進させて圧縮力を発生させるようになる。 More specifically with reference to FIG. 4, the deceleration unit 130 can move forward / backward along the opening / closing direction of the damper cylinder 131 installed in the storage space of the main body 120 and the obstacle 20 in the damper cylinder 131. A shoji is included by including a damper rod 133 that is hinged to the tip of the damper rod 133 so as to be hinged so as to be rotatable by a predetermined angle, and a first hook 135 that is slidably coupled to the first guide groove 121. At the time of closing operation of 20, the locking groove 135a of the first hook 135 is locked to the locking projection 111 of the locking portion 110, and the forward damper rod 133 is moved backward to generate a compressive force.

図５を参照すると、前記第１ガイド溝１２１は、障子２０の閉操作時（図５（ａ）参照）に、第１フック１３５が係止突起１１１に係止された状態で水平移動できるようにガイドする第１直線部１２１ａと、前記障子２０が閉まる方向の第１直線部１２１ａの端部から下向きに傾斜して延設されて、障子２０の開放時（図５（ｂ）参照）に、係止突起１１１から第１フック１３５の係止を解除させることができるように第１フック１３５が旋回しながら載置される第１曲線係止部１２１ｂとからなる。 Referring to FIG. 5, the first guide groove 121 can move horizontally with the first hook 135 locked to the locking projection 111 when the shoji 20 is closed (see FIG. 5A). When the shoji 20 is opened (see FIG. 5 (b)), the first straight line portion 121a guided to the door and the first straight line portion 121a in the direction in which the shoji 20 is closed are extended downward and inclined downward. It is composed of a first curved locking portion 121b on which the first hook 135 is placed while turning so that the locking of the first hook 135 can be released from the locking projection 111.

また、前記第１フック１３５は、ダンパーロッド１３３の先端のヒンジ軸１３３ａに結合され、前記第１曲線係止部１２１ｂ内に自動で旋回載置され得るように、バネ１３５ｂ（図４参照）を媒介として弾性支持可能に結合される。 Further, the first hook 135 is coupled to the hinge shaft 133a at the tip of the damper rod 133, and a spring 135b (see FIG. 4) is provided so that the first hook 135 can be automatically swiveled and mounted in the first curve locking portion 121b. Elastically supportable as a mediator.

図６を参照すると、前記ダンパーシリンダ１３１の内部には、ダンパーロッド１３３の後端のピストン１３３ｂが往復移動可能に結合され、ダンパーロッド１３３の後進時に、前記ピストン１３３ｂが減速区間１３１ａを移動した後、圧力が解除された自由区間１３１ｂを所定距離移動できるように、前記ダンパーシリンダ１３１の内径ｄ１，ｄ２が互いに異なるように形成される。 Referring to FIG. 6, the piston 133b at the rear end of the damper rod 133 is reciprocally coupled to the inside of the damper cylinder 131, and after the piston 133b moves in the deceleration section 131a when the damper rod 133 moves backward. The inner diameters d1 and d2 of the damper cylinder 131 are formed so as to be different from each other so that the free section 131b where the pressure is released can be moved by a predetermined distance.

具体的には、前記減速区間１３１ａの内径ｄ１は、ピストン１３３ｂの移動時に一側のエアバルブＶを介してダンパーシリンダ１３１の内部の空気が外部に抜け出る間に圧力が上昇しながらゆっくり移動できるように、ピストン１３３ｂの外径と対応する大きさに形成される。これに対し、自由区間１３１ｂの内径ｄ２は、ピストン１３３ｂの移動時に圧力がかからないように、減速区間１３１ａの内径ｄ１に比べて大きく形成される。したがって、前記ピストン１３３ｂが自由区間１３１ｂに入る瞬間には圧力がかからないので、減速区間１３１ａに比べてダンパーロッド１３３が速く移動することができる。 Specifically, the inner diameter d1 of the deceleration section 131a can move slowly while the pressure rises while the air inside the damper cylinder 131 escapes to the outside through the air valve V on one side when the piston 133b moves. , Is formed to a size corresponding to the outer diameter of the piston 133b. On the other hand, the inner diameter d2 of the free section 131b is formed larger than the inner diameter d1 of the deceleration section 131a so that pressure is not applied when the piston 133b moves. Therefore, since no pressure is applied at the moment when the piston 133b enters the free section 131b, the damper rod 133 can move faster than the deceleration section 131a.

弾性駆動部１４０は、障子２０の閉操作時に減速部１３０と所定の時間差を置いて作動するものであって、作動時に発生する引張りバネ１４１（図３参照）の弾性復元力を用いて障子２０が容易に閉まるようにする役割を果たす。 The elastic drive unit 140 operates with a predetermined time difference from the deceleration unit 130 when the shoji 20 is closed, and the shoji 20 is operated by using the elastic restoring force of the tension spring 141 (see FIG. 3) generated during the operation. Plays a role in making it close easily.

この場合、前記弾性駆動部１４０は、減速部１３０が減速区間１３１ａから自由区間１３１ｂに進入する時点で作動するように構成することが好ましい。すなわち、減速部１３０の圧縮力と弾性駆動部１４０の弾性復元力が互いに相殺されることを防止することができる。 In this case, it is preferable that the elastic drive unit 140 is configured to operate at the time when the deceleration unit 130 enters the free section 131b from the deceleration section 131a. That is, it is possible to prevent the compressive force of the deceleration unit 130 and the elastic restoring force of the elastic drive unit 140 from canceling each other out.

図７を参照して具体的に説明すると、前記弾性駆動部１４０は、本体部１２０のバネ取付溝１２５内に引張りバネ１４１の一端が固定され、引張りバネ１４１の他端には第２フック１４３が設置される。したがって、第２フック１４３の係止溝１４３ａが係止突起１１１に係止される瞬間、引っ張られていた引張りバネ１４１の弾性復元力によって障子２０を閉まる方向に押して移動させるようになる。 Specifically, with reference to FIG. 7, in the elastic drive unit 140, one end of the tension spring 141 is fixed in the spring mounting groove 125 of the main body unit 120, and the second hook 143 is attached to the other end of the tension spring 141. Is installed. Therefore, at the moment when the locking groove 143a of the second hook 143 is locked to the locking projection 111, the elastic restoring force of the tension spring 141 that has been pulled pushes and moves the shoji 20 in the closing direction.

この場合、前記第２フック１４３は、本体部１２０内の第２ガイド溝１２３に沿ってスライド可能に結合され得るように、両側面にガイドピン１４３ｂが備えられる。 In this case, the second hook 143 is provided with guide pins 143b on both side surfaces so that the second hook 143 can be slidably coupled along the second guide groove 123 in the main body 120.

図８を参照すると、前記第２ガイド溝１２３は、障子２０の閉操作時（図８（ａ）参照）に、第２フック１４３が係止突起１１１に係止された状態で水平移動できるようにガイドする第２直線部１２３ａと、前記障子２０が閉まる方向の第２直線部１２３ａの端部から下向きに傾斜して延設されて、障子２０の開放時（図８（ｂ）参照）に、係止突起１１１から第２フック１４３の係止を解除させることができるように第２フック１４３が旋回しながら載置される第２曲線係止部１２３ｂとからなる。 Referring to FIG. 8, the second guide groove 123 can move horizontally with the second hook 143 locked to the locking projection 111 when the shoji 20 is closed (see FIG. 8A). When the shoji 20 is opened (see FIG. 8B), the second straight line portion 123a guided to the door and the second straight line portion 123a extending downward from the end of the second straight line portion 123a in the closing direction of the shoji 20 are extended. It is composed of a second curved locking portion 123b on which the second hook 143 is placed while turning so that the locking of the second hook 143 can be released from the locking projection 111.

再び図７を参照すると、前記弾性駆動部１４０の一側には、障子２０の荷重や様々な条件などに合わせて引張りバネ１４１の張力を調節できるように張力調節部１５０が備えられてもよい。 Referring to FIG. 7 again, a tension adjusting unit 150 may be provided on one side of the elastic driving unit 140 so that the tension of the tension spring 141 can be adjusted according to the load of the shoji 20 and various conditions. ..

具体的には、前記張力調節部１５０は、前記本体部１２０の装着溝１２７に空回り可能に設置され、一側にドライバー溝が形成されたねじ頭１５１ａが備えられ、他側にねじ山が備えられる調節ねじ１５１と、前記引張りバネ１４１の一端に一体に固定されると共に、前記ねじ山１５１ｂにねじ結合されて、前記調節ねじ１５１の回動操作時にバネ取付溝１２５の長手方向に沿って往復移動する調節ナット１５３とを含む。 Specifically, the tension adjusting portion 150 is installed in the mounting groove 127 of the main body portion 120 so as to be idle, and is provided with a screw head 151a having a driver groove formed on one side and a screw thread on the other side. The adjusting screw 151 is integrally fixed to one end of the tension spring 141, and is screwed to the thread 151b to reciprocate along the longitudinal direction of the spring mounting groove 125 when the adjusting screw 151 is rotated. Includes a moving adjustment nut 153.

この場合、前記調節ねじ１５１のねじ山１５１ｂは、調節ナット１５３にねじ結合された後、引張りバネ１４１内の中心軸線に沿って往復移動可能に挿入される構造であるので、前記ねじ山１５１ｂと引張りバネ１４１が干渉することを防止することができる。 In this case, the thread 151b of the adjusting screw 151 is screw-coupled to the adjusting nut 153 and then inserted so as to be reciprocally movable along the central axis in the tension spring 141. It is possible to prevent the tension spring 141 from interfering with each other.

このような構成の張力調節部１５０は、建具の施工時に、作業者がドライバーなどの道具を用いて、本体部１２０の一側に外部に露出したねじ頭１５１ａを時計方向又は反時計方向に回転操作して調節ナット１５３の位置を移動させることによって、引張りバネ１４１の張力を容易に調節することができる。 In the tension adjusting portion 150 having such a configuration, when the fitting is installed, the operator uses a tool such as a screwdriver to rotate the screw head 151a exposed to the outside on one side of the main body portion 120 clockwise or counterclockwise. By manipulating and moving the position of the adjusting nut 153, the tension of the tension spring 141 can be easily adjusted.

すると、以上のような構成の本発明に係る引違い建具用閉速度減少装置１００の作動原理について、図９Ａ乃至図９Ｄを参照して説明する。 Then, the operating principle of the closing speed reducing device 100 for sliding fittings according to the present invention having the above configuration will be described with reference to FIGS. 9A to 9D.

まず、図９Ａに示されたように、障子２０が開放された場合、減速部１３０の第１フック１３５及び弾性駆動部１４０の第２フック１４３は、係止部１１０の係止突起１１１から係止が解除される。 First, as shown in FIG. 9A, when the shoji 20 is opened, the first hook 135 of the deceleration portion 130 and the second hook 143 of the elastic drive portion 140 are engaged with each other from the locking projection 111 of the locking portion 110. The stop is released.

具体的には、前記減速部１３０の第１フック１３５は、第１ガイド溝１２１の第１曲線係止部１２１ｂ内にガイド・載置されて所定角度旋回した状態である。すなわち、第１フック１３５の係止溝１３５ａは、障子２０の閉鎖時に係止突起１１１に再び係止固定され得るように同一水平線上で係止突起１１１に向かうように配置される。 Specifically, the first hook 135 of the deceleration portion 130 is in a state of being guided and mounted in the first curve locking portion 121b of the first guide groove 121 and swiveling at a predetermined angle. That is, the locking groove 135a of the first hook 135 is arranged so as to be directed toward the locking projection 111 on the same horizon so that it can be locked and fixed to the locking projection 111 again when the shoji 20 is closed.

併せて、弾性駆動部１４０の第２フック１４３は、障子２０が開放される方向に前記第１フック１３５と所定距離離隔して配置され、第２ガイド溝１２３の第２曲線係止部１２３ｂ内にガイド・載置されて所定角度旋回した状態である。すなわち、第２フック１４３の係止溝１４３ａは、前記第１フック１３５の場合と同様に、障子２０の閉鎖時に係止突起１１１に再び係止固定され得るように同一水平線上で係止突起１１１に向かうように配置される。 At the same time, the second hook 143 of the elastic drive unit 140 is arranged at a predetermined distance from the first hook 135 in the direction in which the shoji 20 is opened, and is inside the second curve locking portion 123b of the second guide groove 123. It is in a state where it is guided and placed on the screen and turned by a predetermined angle. That is, the locking groove 143a of the second hook 143 is locked and fixed to the locking projection 111 again when the shoji 20 is closed, as in the case of the first hook 135. Arranged to face.

図９Ｂを参照すると、障子２０の閉操作時には、障子２０が窓枠１０に向かってスライド移動しながら、窓枠１０の所定の地点に設置された係止突起１１１に減速部１３０の第１フック１３５が先に係止固定される。 Referring to FIG. 9B, when the shoji 20 is closed, the shoji 20 slides toward the window frame 10 and the first hook of the deceleration unit 130 is attached to the locking projection 111 installed at a predetermined point of the window frame 10. 135 is locked and fixed first.

この場合、第１フック１３５は、障子２０の移動方向と反対方向である第１ガイド溝１２１の第１曲線係止部１２１ｂから第１直線部１２１ａ側にガイド・移動しながら、ダンパーロッド１３３が後進するようになる。言い換えると、急速に閉まる障子２０は、ダンパーロッド１３３の後進時にダンパーシリンダ１３１内に発生する圧縮力によって速度が減少するようになる。このとき、障子２０の減速移動距離は、ダンパーシリンダ１３１内の減速区間１３１ａ（図６参照）に該当する。 In this case, the damper rod 133 guides and moves the first hook 135 from the first curve locking portion 121b of the first guide groove 121, which is in the direction opposite to the moving direction of the shoji 20, toward the first straight portion 121a. You will move backwards. In other words, the speed of the shoji 20 that closes rapidly decreases due to the compressive force generated in the damper cylinder 131 when the damper rod 133 moves backward. At this time, the deceleration movement distance of the shoji 20 corresponds to the deceleration section 131a (see FIG. 6) in the damper cylinder 131.

図９Ｃを参照すると、障子２０が前記減速区間１３１ａを移動した後は、ダンパーシリンダ１３１内の自由区間１３１ｂ（図６参照）に進入するようになる。すなわち、自由区間１３１ｂを通過するようになる障子２０は、減速区間１３１ａで作用していた圧力が解除されることによって、障子２０の容易な移動が可能になる。 Referring to FIG. 9C, after the shoji 20 moves in the deceleration section 131a, it enters the free section 131b (see FIG. 6) in the damper cylinder 131. That is, the shoji 20 passing through the free section 131b can be easily moved by releasing the pressure acting on the deceleration section 131a.

この場合、前記障子２０がダンパーシリンダ１３１の減速区間１３１ａから自由区間１３１ｂに進入する瞬間、前記弾性駆動部１４０の第２フック１４３が係止突起１１１に係止されるようになる。 In this case, at the moment when the shoji 20 enters the free section 131b from the deceleration section 131a of the damper cylinder 131, the second hook 143 of the elastic drive unit 140 is locked to the locking projection 111.

これと同時に、引っ張られていた引張りバネ１４１の弾性復元力が作用することによって、障子２０を閉まる方向に押して移動させるようになり、これによって、図９Ｄのように、障子２０の容易な閉操作が完了する。 At the same time, the elastic restoring force of the tension spring 141 that has been pulled acts to push and move the shoji 20 in the closing direction, whereby the shoji 20 can be easily closed as shown in FIG. 9D. Is completed.

一方、障子２０の開放時には、図９Ａ乃至図９Ｄで順次示した過程の逆順に減速部１３０と弾性駆動部１４０が作動するようになる。 On the other hand, when the shoji 20 is opened, the deceleration unit 130 and the elastic drive unit 140 operate in the reverse order of the processes shown in FIGS. 9A to 9D.

以上では、本発明を特定の具体的な実施例を挙げて図示し、説明したが、本発明は、前記の実施例に限定されず、本発明の技術思想を逸脱しない範囲内で様々な変更及び修正が可能であることは勿論である。 In the above, the present invention has been illustrated and described with reference to specific specific examples, but the present invention is not limited to the above-mentioned examples, and various modifications are made without departing from the technical idea of the present invention.
