Description

この発明は、弾性部材の弾性力によって引戸を閉扉する引戸用クローザ装置に関する。   The present invention relates to a closing device for a sliding door that closes the sliding door by an elastic force of an elastic member.

引戸用クローザ装置の一実施形態を図７に示して説明すると、この引戸用クローザ装置１は、引戸２の扉枠に設けたケーシング４に、開閉方向のガイド溝５が設けられ、このガイド溝５の開扉方向の端部には上記開閉方向と直角に交差して上方に伸びる退去部６が設けられている。また、このガイド溝５に沿って移動自在のスライダ７が設けられ、このスライダ７には、そのスライダ７に対し水平軸周りに回転自在であるとともにガイド溝５に嵌る水平移動軸２３及び突出軸１５を有するカム部材１１が設けられている。このカム部材１１に形成された突出部２４とケーシング４とは弾性部材１３で連結され、ガイド溝５の開閉方向に沿ってこのカム部材１１に付勢力を与える。   An embodiment of the sliding door closer device will be described with reference to FIG. 7. In this sliding door closer device 1, a guide groove 5 in the opening / closing direction is provided in a casing 4 provided in a door frame of the sliding door 2, and this guide groove is provided. 5 is provided with a retracting portion 6 that intersects the opening / closing direction at right angles and extends upward. In addition, a slider 7 that is movable along the guide groove 5 is provided. The slider 7 is rotatable about the horizontal axis with respect to the slider 7 and has a horizontal movement shaft 23 and a protruding shaft that fit into the guide groove 5. A cam member 11 having 15 is provided. The projecting portion 24 formed on the cam member 11 and the casing 4 are connected by an elastic member 13 and applies a biasing force to the cam member 11 along the opening / closing direction of the guide groove 5.

また、引戸２には、カム部材１１に向かって突出するブロック部２０が設けられ、引戸２が閉められている際には、このブロック部２０はカム部材１１に係合している。引戸２を開ける際には、ブロック部２０が、カム部材１１に係合したままこのカム部材１１及びスライダ７を弾性部材１３の弾性力に抗して開扉方向に移動させる。   The sliding door 2 is provided with a block portion 20 that protrudes toward the cam member 11, and the block portion 20 is engaged with the cam member 11 when the sliding door 2 is closed. When opening the sliding door 2, the block portion 20 moves the cam member 11 and the slider 7 in the door opening direction against the elastic force of the elastic member 13 while being engaged with the cam member 11.

カム部材１１の突出軸１５がガイド溝５の端部に来ると、突出軸１５は上記開扉方向への移動が不能になるとともに、ブロック部２０がこのカム部材１１を開扉方向に押して、このカム部材１１をスライダ７に対して上記水平軸周りに回転させる。この回転に伴って、突出軸１５が退去部６に入り込んでその退去部６の内面に係合し、その位置で弾性部材１３の弾性力によりカム部材１１がロックされる（図７の仮想線参照）。   When the protruding shaft 15 of the cam member 11 reaches the end of the guide groove 5, the protruding shaft 15 cannot move in the door opening direction, and the block portion 20 pushes the cam member 11 in the door opening direction. The cam member 11 is rotated around the horizontal axis with respect to the slider 7. With this rotation, the protruding shaft 15 enters the retracting portion 6 and engages with the inner surface of the retracting portion 6, and the cam member 11 is locked by the elastic force of the elastic member 13 at that position (the phantom line in FIG. 7). reference).

また引戸２を閉める際は、ブロック部２０がカム部材１１をスライダ７に対して上記水平軸周りに回転させ、その回転とともに突出軸１５が退去部６から離脱する。さらにこのブロック部２０がカム部材１１に係合し、弾性部材１３の弾性力によってカム部材１１およびスライダ７が閉扉方向へ移動する。このスライダ７には弾性部材１３と平行してダンパー１４が設けられ、このダンパー１４が、上記閉扉の際に弾性部材１３の弾性力によって引戸２が加速されて勢いよく閉まるのを防止する。   When closing the sliding door 2, the block portion 20 rotates the cam member 11 around the horizontal axis with respect to the slider 7, and the protruding shaft 15 is detached from the retracting portion 6 with the rotation. Further, the block portion 20 is engaged with the cam member 11, and the cam member 11 and the slider 7 are moved in the door closing direction by the elastic force of the elastic member 13. The slider 7 is provided with a damper 14 in parallel with the elastic member 13, and this damper 14 prevents the sliding door 2 from being accelerated by the elastic force of the elastic member 13 when the door is closed, and closes vigorously.

図に示す引戸用クローザのカム部材には、上記ガイド溝の突出軸とともに水平移動軸が設けられ、上記水平移動軸が上記ガイド溝の開閉方向部内に嵌まり込んだ状態で上記突出軸が上記退去部に嵌まり込むことによって上記カム部材の回転がなされるため、上記水平移動軸を中心とした大きな回転半径を要する。そのため、この回転半径に対応して上記ガイド溝の上記退去部側に上記カム部材の端部が回避するためのスペースを確保する必要があり、そのスペースの分だけ、引戸用クローザ装置のコンパクト化が図れないという問題がある。   The sliding door closer cam member shown in the drawing is provided with a horizontal movement shaft together with the protruding shaft of the guide groove, and the protruding shaft is fitted in the opening / closing direction portion of the guide groove. Since the cam member is rotated by being fitted into the retracted portion, a large radius of rotation about the horizontal movement axis is required. Therefore, it is necessary to secure a space for avoiding the end of the cam member on the retracted portion side of the guide groove corresponding to the turning radius, and the sliding device closer device is made compact by the amount of the space. There is a problem that cannot be achieved.

そこで、この発明は、引戸用クローザ装置のコンパクト化を図ることを課題とする。   Therefore, an object of the present invention is to make the sliding door closer device compact.

上記の課題を解決するため、この発明は、引戸用クローザ装置において、上記退去部に、上記ガイド溝と退去部との間の突部の先端よりも閉扉方向側に窪んだ凹部を形成し、スライダに退去部の上記凹部側に伸びる長孔を形成し、この長孔内に、カム部材に設けたピンがその長孔の長さ方向に沿って移動自在に嵌るとともに、上記カム部材は上記ピンを介して上記スライダに対し上記ピンの軸周りに回転自在とし、上記ブロック部が上記カム部材を回転させる際に、上記ピンが上記長孔内を移動して上記突出軸を上記退去部に係脱させることにしたのである。 In order to solve the above problems, the present invention provides a sliding door closer device, wherein the recessed portion is formed with a recessed portion that is recessed toward the door closing direction from the tip of the protruding portion between the guide groove and the retracting portion. A long hole extending toward the concave portion of the retracting portion is formed in the slider, and a pin provided on the cam member is movably fitted in the long hole along the length direction of the long hole. The pin is allowed to rotate about the axis of the pin with respect to the slider, and when the block portion rotates the cam member, the pin moves in the elongated hole and the protruding shaft becomes the retracted portion. I decided to detach it.

この長孔は、上記ガイド溝に形成した退去部が伸びる方向と同方向に形成されているので、上記ブロック部が上記カム部材を開扉方向に押した際に、上記長孔内に嵌る上記ピンが上記退去部方向に誘導されるとともに、このピンが設けられたカム部材もこの退去部に誘導される。逆に、上記ピンが上記退去部から上記ガイド溝の水平部に戻る際、このカム部材も上記水平部に誘導される。このため、上記突出軸の上記退去部への上記係脱が円滑になされる。   Since the long hole is formed in the same direction as the extension part formed in the guide groove extends, the block part fits in the long hole when the cam member is pushed in the door opening direction. The pin is guided toward the retracted portion, and the cam member provided with the pin is also guided to the retracted portion. Conversely, when the pin returns from the retracted portion to the horizontal portion of the guide groove, the cam member is also guided to the horizontal portion. For this reason, the engagement / disengagement of the protruding shaft with respect to the withdrawal portion is smoothly performed.

このカム部材は上記突出軸を回転軸として回転し、しかも、この突出軸は上記退去部にこの突出軸を係止する係止片の役割を兼ねている。そのため、図に示すようにカム部材の回転軸と回転させたカム部材を係止するための軸とを別個に設ける場合と比較して、このカム部材の回転半径を小さく抑えることができる。このため、上記カム部材の端部が上記退去部側に大きく突出しない。   The cam member rotates with the protruding shaft as a rotation shaft, and the protruding shaft also serves as a locking piece for locking the protruding shaft to the retracted portion. Therefore, as shown in the figure, the rotation radius of the cam member can be kept small compared to the case where the rotation shaft of the cam member and the shaft for locking the rotated cam member are provided separately. For this reason, the edge part of the said cam member does not protrude large in the said withdrawal part side.

また、上記突出軸に、上記開閉方向に伸びるガイド溝に沿って誘導される平行部と、上記退去部の前記凹部に入り込むことによりその凹部の内面に係合するフック部とを設け、上記ピンを上記フック部に設けるようにする。
このようにすれば、上記フック部が上記退去部に係合した際に、このフック部に設けたピンが、上記スライダを介して、上記弾性部材によって閉扉方向に付勢される。この付勢によって上記退去部からフック部が外れにくい。
Further, the projecting shaft is provided with a parallel portion guided along the guide groove extending in the opening and closing direction, and a hook portion engaging with the inner surface of the recessed portion by entering the recessed portion of the retracted portion, and the pin the it is provided in the hook portion.
If it does in this way, when the said hook part engages with the said withdrawal part, the pin provided in this hook part will be urged | biased by the said elastic member in the door closing direction via the said slider. By this urging, the hook part is unlikely to come off from the retracted part.

さらに、上記スライダとケーシング又は上記引戸をダンパーで連結するようにすることもできる。このようにすれば、このダンパーが、上記閉扉の際に上記弾性部材の弾性力によって引戸が加速されて勢いよく閉まるのを防止するので、この引戸に挟まれて怪我をする恐れが低い。   Furthermore, the slider and the casing or the sliding door can be connected by a damper. In this way, the damper prevents the sliding door from being accelerated and closed by the elastic force of the elastic member when the door is closed, so there is little risk of injury due to being caught by the sliding door.

この発明によると、上記カム部材の回転軸が上記フック部を兼ねているので、上記引戸用クローザ装置のカム部材の回転半径を小さく抑えることができる。このため、引戸用クローザ装置のコンパクト化を図ることができる。   According to this invention, since the rotating shaft of the cam member also serves as the hook portion, the rotation radius of the cam member of the closing device for the sliding door can be kept small. For this reason, the closer device for a sliding door can be made compact.

この発明の引戸用クローザ装置１は、引戸２又は引戸２の扉枠３（例えば、図１（ａ）に示すように鴨居）に設けて使用するものである。   The closer device 1 for a sliding door according to the present invention is used by being provided on a sliding door 2 or a door frame 3 of the sliding door 2 (for example, a duck as shown in FIG. 1A).

この引戸用クローザ装置１を図２及び図３に示して説明する。この引戸用クローザ装置１は、ケーシング４に、この引戸２の開閉方向のガイド溝５が形成され、この端部には、上記開閉方向と交差して上方に伸びる退去部６が形成されている。このガイド溝５にはスライダ７が設けられ、このスライダ７に形成されたスライド軸８がガイド溝５に嵌まり込むことによって、上記開閉方向にこのスライダ７が移動自在となっている。   This sliding door closer device 1 will be described with reference to FIGS. In the closing device 1 for a sliding door, a guide groove 5 in the opening / closing direction of the sliding door 2 is formed in a casing 4, and a withdrawal portion 6 extending upward is formed at the end portion so as to intersect the opening / closing direction. . A slider 7 is provided in the guide groove 5, and when the slide shaft 8 formed in the slider 7 is fitted into the guide groove 5, the slider 7 is movable in the opening / closing direction.

このスライダ７には、退去部６と同方向に伸びる長孔９が形成され、この長孔９に設けたピン１０によって、このスライダ７に対し水平軸周りに回転自在にカム部材１１が設けられている。このピン１０は長孔９内を移動自在に設けられている。   The slider 7 is formed with a long hole 9 extending in the same direction as the retracting portion 6, and a cam member 11 is rotatably provided around the horizontal axis with respect to the slider 7 by a pin 10 provided in the long hole 9. ing. The pin 10 is provided so as to be movable in the long hole 9.

また、このスライダ７にはねじ部１２が形成され、このねじ部１２にばね１３の一端が接続され、このばね１３の他端はケーシング４に固定されている。
また、ばね１３と同軸に、このねじ部１２にはダンパー１４の一端がねじ込まれ、このダンパー１４の他端もケーシング４に固定されている。 The slider 7 is formed with a threaded portion 12, one end of a spring 13 is connected to the threaded portion 12, and the other end of the spring 13 is fixed to the casing 4.
Also, one end of a damper 14 is screwed into the threaded portion 12 coaxially with the spring 13, and the other end of the damper 14 is also fixed to the casing 4.

また、図４に示すように、カム部材１１には突出軸１５が形成され、この突出軸１５は上記開閉方向に伸びるガイド溝５に沿って誘導される平行部１６と、退去部６に入り込んでその退去部６の内面に係合するフック部１７とを備えている。この平行部１６によって、突出軸１５はケーシング４に形成されたガイド溝５及び退去部６を自在に移動できる。このフック部１７には貫通孔１８が形成され、この貫通孔１８にピンが挿入される。
さらに、このカム部材１１には係合片１９が設けられ、この係合片１９に、引戸２にカム部材１１に向かって突出して設けられたブロック部２０が係合するようになっている。 As shown in FIG. 4, the cam member 11 has a protruding shaft 15, and the protruding shaft 15 enters the parallel portion 16 guided along the guide groove 5 extending in the opening and closing direction and the retracted portion 6. And a hook portion 17 that engages with the inner surface of the retracting portion 6. By this parallel portion 16, the protruding shaft 15 can freely move in the guide groove 5 and the withdrawal portion 6 formed in the casing 4. A through hole 18 is formed in the hook portion 17, and a pin is inserted into the through hole 18.
Further, the cam member 11 is provided with an engagement piece 19, and a block portion 20 provided so as to protrude from the sliding door 2 toward the cam member 11 is engaged with the engagement piece 19.

この引戸２を開ける際には、図５及び図６に示すように、このブロック部２０をカム部材１１の係合片１９に係合させて、そのカム部材１１及びスライダ７をばね１３の弾性力に抗して引き伸ばし、開扉方向に移動させる。カム部材１１に設けた突出軸１５がガイド溝５の端部に来ると、このブロック部２０がカム部材１１をスライダ７に対して上記水平軸周りに反時計方向に回転させる。その回転とともにこの突出軸１５が退去部６の内面に当接しながら、その退去部６に入り込んで係合する。   When opening the sliding door 2, as shown in FIGS. 5 and 6, the block portion 20 is engaged with the engagement piece 19 of the cam member 11, and the cam member 11 and the slider 7 are elasticized by the spring 13. Stretch against the force and move in the opening direction. When the protruding shaft 15 provided on the cam member 11 comes to the end of the guide groove 5, the block portion 20 rotates the cam member 11 counterclockwise around the horizontal axis with respect to the slider 7. With this rotation, the projecting shaft 15 contacts and engages with the inner surface of the retracting portion 6.

この係合の際、長孔９内を移動自在に設けられたピン１０が長孔９内の最下部から上方に移動する（図６におけるピン１０ａ→１０ｂ）ので、突出軸１５の回転中心もそれとともに、退去部６に移動する。この際、カム部材１１は、ばね１３によってこのピン１０を介して閉扉方向に付勢されているので、このばね１３の弾性力によってカム部材１１は退去部６でロックされた状態となる。
しかも、この退去部６の閉扉側に突部２１が形成されているので、この突部２１によってピン１０が退去部６から外れるのが防止され、上記ロックの効果が一層高いものとなる。このロックの強弱は退去部６及び突部２１の形状を変えて突出軸１５との係合度合いを変えることによって、適宜調節することができる。 At the time of this engagement, the pin 10 movably provided in the long hole 9 moves upward from the lowermost part in the long hole 9 (pin 10a → 10b in FIG. 6). At the same time, it moves to the leaving unit 6. At this time, since the cam member 11 is urged by the spring 13 through the pin 10 in the door closing direction, the cam member 11 is locked by the retracting portion 6 by the elastic force of the spring 13.
In addition, since the protruding portion 21 is formed on the door closing side of the retracting portion 6, the protruding portion 21 prevents the pin 10 from being detached from the retracting portion 6, and the locking effect is further enhanced. The strength of the lock can be adjusted as appropriate by changing the shape of the retracting portion 6 and the protruding portion 21 to change the degree of engagement with the protruding shaft 15.

また、この引戸２を閉める際には、ブロック部２０をカム部材１１の当接部２２に当接させ、このカム部材１１をスライダ７に対し上記水平軸周りに時計方向に回転させ、その回転とともに突出軸１５を退去部６から離脱させる。さらに、このブロック部２０がカム部材１１の係合片１９に係合してこのカム部材１１及びスライダ７をばね１３の弾性力によって閉扉方向に移動させる。   When the sliding door 2 is closed, the block portion 20 is brought into contact with the contact portion 22 of the cam member 11, and the cam member 11 is rotated clockwise around the horizontal axis with respect to the slider 7, and the rotation thereof is performed. At the same time, the protruding shaft 15 is separated from the retracting portion 6. Further, the block portion 20 engages with the engagement piece 19 of the cam member 11 to move the cam member 11 and the slider 7 in the closing direction by the elastic force of the spring 13.

このスライダ７とケーシング４はダンパー１４で連結したので、このダンパー１４が上記閉扉の際にばね１３の弾性力によって引戸２が加速されて勢いよく閉まるのを防止し、この引戸２に挟まれて怪我をする恐れが低い。   Since the slider 7 and the casing 4 are connected by the damper 14, the sliding door 2 is prevented from being accelerated and closed by the elastic force of the spring 13 when the damper 14 is closed, and is sandwiched by the sliding door 2. Low risk of injury.

この引戸用クローザ装置１においては、引戸２の扉枠側にブロック部２０を設け、引戸２側にこの引戸２の開閉方向のガイド溝５、スライダ７、及び、カム部材１１を設けるようにすることもできる。
また、壁側にこの引戸２の開閉方向のガイド溝５を設け、スライダ７に対しカム部材１１をピン１０によって垂直軸周りに回転自在に設け、このカム部材１１がガイド溝５をガイドされるようにすることもできる。 In the sliding door closer device 1, the block portion 20 is provided on the door frame side of the sliding door 2, and the guide groove 5, the slider 7, and the cam member 11 in the opening / closing direction of the sliding door 2 are provided on the sliding door 2 side. You can also.
Further, a guide groove 5 in the opening / closing direction of the sliding door 2 is provided on the wall side, and a cam member 11 is provided on the slider 7 so as to be rotatable around a vertical axis by a pin 10. It can also be done.
