Description

本発明は、引戸を閉まり際において緩やかに閉める引戸の引き込み装置に関する。   The present invention relates to a sliding door retracting device that closes gently when closing a sliding door.

特許文献１に記載される引戸の引き込み装置は、枠体に設けられた装置本体と引戸に設けられ装置本体を操作する操作部材とを備える。装置本体には、枠体に固定されたガイドレール部と、ガイドレール部に案内されて往復移動する引き込み部材とが設けられる。引き込み部材は、コイルばねによって引戸の閉方向に付勢され、ガイドレール部に設けられたラックと噛み合う複数のピニオンギアを備えており、ピニオンギアには各々一方向性回転ダンパーが連結されている。   The sliding door retracting device described in Patent Document 1 includes an apparatus main body provided on the frame body and an operation member provided on the sliding door and operating the apparatus main body. The apparatus main body is provided with a guide rail portion fixed to the frame and a retracting member that is guided by the guide rail portion to reciprocate. The pull-in member is biased by a coil spring in the closing direction of the sliding door, and includes a plurality of pinion gears that mesh with a rack provided on the guide rail portion, and a unidirectional rotating damper is connected to each pinion gear. .

一方向性回転ダンパーが連結されたピニオンギアは、引戸が閉じられる方向に移動するときに一方向性回転ダンパーから抵抗力を受けて減速する。複数のピニオンギアのうちの一部のピニオンギアがラックから外れて直線部に移ると、該ピニオンギアは回転しないので一方向性回転ダンパーからの抵抗力を受けなくなる。引き込み部材が戸先側に移動するにしたがって一方向性回転ダンパーからの抵抗力を減少させて、コイルばねの付勢力を小さくしている。   The pinion gear to which the unidirectional rotating damper is coupled is decelerated by receiving a resistance force from the unidirectional rotating damper when moving in the direction in which the sliding door is closed. When a part of the plurality of pinion gears moves out of the rack and moves to the straight line portion, the pinion gears do not rotate and thus do not receive the resistance force from the unidirectional rotating damper. As the retracting member moves to the door end side, the resistance force from the unidirectional rotating damper is reduced to reduce the biasing force of the coil spring.

ガイド部材６は、たとえば樹脂成型され、上枠２に固定されるガイド部材本体９と、ガイド部材本体９との間に引き込み部材８を挟みこんだ状態でガイド部材本体９に取り付けられるガイド部材カバー２０とを備える。ガイド部材本体９とガイド部材カバー２０とには、引き込み部材８の側面を案内する案内溝７ａと７ｂとが各々設けられる。案内溝７ａ，７ｂは、引戸４の開閉方向である水平方向に形成され、戸尻側の端部には戸尻方向に向かって斜めに高くなる傾斜部１１と傾斜部１１に連設されて垂直に立ち上がる立ち上がり部１２とが形成される。   The guide member 6 is, for example, a resin-molded guide member body 9 that is fixed to the upper frame 2 and a guide member cover that is attached to the guide member body 9 with the pull-in member 8 sandwiched between the guide member body 9. 20. The guide member body 9 and the guide member cover 20 are provided with guide grooves 7a and 7b for guiding the side surfaces of the retracting member 8, respectively. The guide grooves 7a and 7b are formed in the horizontal direction that is the opening and closing direction of the sliding door 4, and are connected to the inclined portion 11 and the inclined portion 11 that are inclined obliquely toward the door bottom direction at the end of the door bottom side. A rising portion 12 rising vertically is formed.

ガイド部材本体９の案内溝７ａの上方には、戸尻側から戸先側に向かって順番にラック１０ａと１０ｂとが設置される。ラック１０ａ，１０ｂは、引き込み部材８のピニオンギア１３ａ，１３ｂと夫々噛み合う。   Above the guide groove 7a of the guide member body 9, racks 10a and 10b are installed in order from the door bottom side to the door tip side. The racks 10a and 10b mesh with the pinion gears 13a and 13b of the retracting member 8, respectively.

引き込み部材８は、一方向性回転ダンパー１４と一方向性回転ダンパー１４の回転軸２１に連設されるピニオンギア１３ａ，１３ｂとが設けられた制動部１５と、制動部１５の戸尻側に回動可能に支持され操作部材５が係合する係合部１６とを備える。制動部１５は、直方体の箱状に形成されたハウジング部１８を備えている。一方向性回転ダンパー１４は回転軸２１が垂直上方に向いた状態でハウジング部１８の内部にねじ止めされる。回転軸２１はハウジング部１８の上方に突出しており、ピニオンギア１３ａ，１３ｂが回転軸２１の軸端に固定される。ピニオンギア１３ｂのピッチ円直径は、ピニオンギア１３ａのピッチ円直径よりも大径に形成される。   The retracting member 8 includes a braking portion 15 provided with a unidirectional rotating damper 14 and pinion gears 13 a and 13 b connected to a rotating shaft 21 of the unidirectional rotating damper 14, and a door bottom side of the braking portion 15. And an engaging portion 16 that is rotatably supported and engages with the operation member 5. The braking portion 15 includes a housing portion 18 formed in a rectangular parallelepiped box shape. The unidirectional rotating damper 14 is screwed inside the housing portion 18 with the rotating shaft 21 facing vertically upward. The rotating shaft 21 protrudes above the housing portion 18, and the pinion gears 13 a and 13 b are fixed to the shaft end of the rotating shaft 21. The pitch circle diameter of the pinion gear 13b is formed larger than the pitch circle diameter of the pinion gear 13a.

ハウジング部１８の側面には、案内溝７ａ，７ｂに係合する係合凸部１９が移動方向に沿って各々２箇所ずつ設けられる。ハウジング部１８の戸尻側には、係合部１６を支持する支持部２２がハウジング部１８と一体的に形成されている。支持部２２は、制動部１５が移動する方向と直交する幅方向に細長に形成された円筒形である。係合部１６は、垂直方向に立ち上がった平板部２３を備える。平板部２３は下方に開口したコの字状である。平板部２３の前部には、支持部２２が嵌め込まれる円弧状の凹部２４が形成される。支持部２２が凹部２４に嵌め込まれて、係合部１６は、支持部２２の水平方向に向いた軸心を中心として回動可能に支持される。   On the side surface of the housing portion 18, two engaging convex portions 19 that engage with the guide grooves 7 a and 7 b are provided along the moving direction. A support portion 22 that supports the engaging portion 16 is formed integrally with the housing portion 18 on the door bottom side of the housing portion 18. The support portion 22 has a cylindrical shape that is elongated in the width direction perpendicular to the direction in which the braking portion 15 moves. The engaging portion 16 includes a flat plate portion 23 that rises in the vertical direction. The flat plate portion 23 has a U-shape that opens downward. An arcuate recess 24 into which the support portion 22 is fitted is formed in the front portion of the flat plate portion 23. The support portion 22 is fitted in the recess 24, and the engagement portion 16 is supported so as to be rotatable about the axis of the support portion 22 facing in the horizontal direction.

平板部２３の後部には係合凸部２５が平板部２３と一体的に形成される。係合凸部２５は、平板部２３の両面から水平方向に突出した細長な円筒形である。引き込み部材８は、ハウジング部１８の係合凸部１９と支持部２２の端部と係合凸部２５の端部とがガイド部材６の案内溝７ａ，７ｂに係合して、案内溝７ａ，７ｂに沿って移動する。   An engaging convex part 25 is formed integrally with the flat plate part 23 at the rear part of the flat plate part 23. The engagement convex part 25 is an elongated cylindrical shape protruding in the horizontal direction from both surfaces of the flat plate part 23. The pull-in member 8 is such that the engaging convex portion 19 of the housing portion 18, the end portion of the support portion 22, and the end portion of the engaging convex portion 25 engage with the guide grooves 7 a and 7 b of the guide member 6. , 7b.

平板部２３は、戸先側の脚部２６と戸尻側の脚部２７とを備える。ガイド部材６の下部であって、ガイド部材本体９とガイド部材カバー２０との接合部には、引戸４の開閉方向に沿って細長な溝部２９が形成されており、係合部１６は、脚部２６と脚部２７とが溝部２９に挿通された状態で移動可能である。制動部１５は、ガイド部材本体９の戸先側に設けられたぜんまいばね１７によって戸先側に付勢されている。   The flat plate portion 23 includes a door-side leg 26 and a door-side leg 27. An elongated groove 29 is formed along the opening / closing direction of the sliding door 4 at the joint between the guide member main body 9 and the guide member cover 20 at the lower part of the guide member 6. The part 26 and the leg part 27 can move while being inserted through the groove part 29. The braking portion 15 is biased toward the door tip side by a mainspring spring 17 provided on the door tip side of the guide member main body 9.

引戸４が開けられた状態では、図４に示すように係合部１６の係合凸部２５が案内溝７ａと７ｂの立ち上がり部１２に係合して、係合部１６は斜めに傾斜している。引戸４を戸先側に閉めていくと、操作部材５は、戸尻側の脚部２７に当たることなく戸先側の脚部２６に当接する。引戸４をさらに戸先側に移動すると、係合凸部２５が操作部材５に押されて案内溝７ａと７ｂの立ち上がり部１２から外れ、引き込み部材８は戸先側に移動する。   In the state in which the sliding door 4 is opened, as shown in FIG. 4, the engaging convex portion 25 of the engaging portion 16 is engaged with the rising portion 12 of the guide grooves 7a and 7b, and the engaging portion 16 is inclined obliquely. ing. When the sliding door 4 is closed to the door end side, the operation member 5 comes into contact with the door end side leg portion 26 without hitting the door end side leg portion 27. When the sliding door 4 is further moved to the door-end side, the engaging convex portion 25 is pushed by the operation member 5 to be disengaged from the rising portions 12 of the guide grooves 7a and 7b, and the retracting member 8 is moved to the door-end side.

引き込み部材８が戸先側に移動すると、ラック１０ａと噛み合っているピニオンギア１３ａが回転する。引き込み部材８は、ピニオンギア１３ａの回転速度に応じた抵抗力を一方向性回転ダンパー１４から受けて減速される。引き込み部材８がさらに戸先側に移動すると、ピニオンギア１３ａとラック１０ａとの噛み合いが解除されて、ピニオンギア１３ａと同一回転軸２１上に設置されピニオンギア１３ａよりもピッチ円直径が大きいピニオンギア１３ｂがラック１０ｂと噛み合う。ピッチ円直径が大きいピニオンギア１３ｂの回転速度はピニオンギア１３ａの回転速度よりも低くなるので、引き込み部材８が一方向性回転ダンパー１４から受ける抵抗力は小さくなる。引き込み部材８がさらに戸先側に移動して、ピニオンギア１３ｂとラック１０ｂとの噛み合いが解除されると、引き込み部材８は一方向性回転ダンパー１４から抵抗力を受けなくなり、引戸４は一方向性回転ダンパー１４からの抵抗力を受けない状態で閉め切られる。   When the retracting member 8 moves to the door end side, the pinion gear 13a meshing with the rack 10a rotates. The retracting member 8 receives a resistance force according to the rotational speed of the pinion gear 13a from the unidirectional rotating damper 14 and is decelerated. When the retracting member 8 further moves to the door end side, the meshing between the pinion gear 13a and the rack 10a is released, and the pinion gear that is installed on the same rotation shaft 21 as the pinion gear 13a and has a larger pitch circle diameter than the pinion gear 13a. 13b meshes with the rack 10b. Since the rotational speed of the pinion gear 13b having a large pitch circle diameter is lower than the rotational speed of the pinion gear 13a, the resistance force that the drawing member 8 receives from the unidirectional rotating damper 14 is reduced. When the retracting member 8 further moves to the door end side and the meshing between the pinion gear 13b and the rack 10b is released, the retracting member 8 does not receive the resistance force from the unidirectional rotating damper 14, and the sliding door 4 is unidirectional. It closes in the state which does not receive the resistance force from the sex rotation damper 14.

閉め切られた状態から引戸４が開けられると、引き込み部材８は、操作部材５が戸尻側の脚部２７に当接する。引き込み部材８をさらに戸尻側に移動すると、ピニオンギア１３ｂがラック１０ｂとが噛み合う。ピニオンギア１３ｂとラック１０ｂとの噛み合いが解除された後に、ピニオンギア１３ｂと同一回転軸２１上に設置されたピニオンギア１３ａがラック１０ａと噛み合う。このときピニオンギア１３ａ，１３ｂに連結された一方向性回転ダンパー１４は引戸４が閉められるときの回転方向とは逆方向に回転するので、引き込み部材８が一方向性回転ダンパー１４から抵抗力を受けることはない。係合部１６の戸尻側係合凸部２５は水平方向の案内溝７ａと７ｂから傾斜部１１へ移動し、さらに傾斜部１１から立ち上がり部１２に移動する。係合部１６は、図５の紙面に対して反時計回りに回転し、脚部２７に当接していた操作部材５は脚部２７から離れる。   When the sliding door 4 is opened from the closed state, the operation member 5 of the retracting member 8 contacts the leg 27 on the door bottom side. When the retracting member 8 is further moved to the door bottom side, the pinion gear 13b meshes with the rack 10b. After the meshing between the pinion gear 13b and the rack 10b is released, the pinion gear 13a installed on the same rotation shaft 21 as the pinion gear 13b meshes with the rack 10a. At this time, the unidirectional rotating damper 14 connected to the pinion gears 13a and 13b rotates in the direction opposite to the rotating direction when the sliding door 4 is closed, so that the retracting member 8 receives a resistance force from the unidirectional rotating damper 14. I will not receive it. The door bottom side engaging convex portion 25 of the engaging portion 16 moves from the horizontal guide grooves 7a and 7b to the inclined portion 11, and further moves from the inclined portion 11 to the rising portion 12. The engaging portion 16 rotates counterclockwise with respect to the paper surface of FIG. 5, and the operation member 5 that has been in contact with the leg portion 27 is separated from the leg portion 27.

引戸４の戸先側と戸尻側とには竪枠３０ａ，３０ｂが設けられており、竪枠３０ａ，３０ｂの上端が上枠２によって連結されている。引戸４の上端にはブラケット３１，３１が２箇所取り付けられており、上枠２はブラケット３１，３１に取り付けられた滑車３２，３２に支持される。なお、上枠２には、引戸４の開閉方向に沿ってレール部材３３が取り付けられており、滑車３２，３２はレール部材３３に回転自在に支持される。ブラケット３１，３１にはレール部材３３の下面に当接して滑車３２，３２がレールから脱落することを防止するガイド棒３４，３４が設けられている。操作部材５は、滑車３２，３２の間に設置されたブラケット３５を介して引戸４に固定される。なお、引戸４の下端には扉の開閉方向に沿った溝部２８が設けられており、引戸４は溝部２８が揺れ止めピン３６に係合した状態で移動する。   On the door end side and the door bottom side of the sliding door 4, frame frames 30 a and 30 b are provided, and the upper ends of the frame frames 30 a and 30 b are connected by the upper frame 2. Two brackets 31, 31 are attached to the upper end of the sliding door 4, and the upper frame 2 is supported by pulleys 32, 32 attached to the brackets 31, 31. A rail member 33 is attached to the upper frame 2 along the opening / closing direction of the sliding door 4, and the pulleys 32 and 32 are rotatably supported by the rail member 33. The brackets 31, 31 are provided with guide bars 34, 34 that contact the lower surface of the rail member 33 and prevent the pulleys 32, 32 from falling off the rail. The operation member 5 is fixed to the sliding door 4 via a bracket 35 installed between the pulleys 32 and 32. In addition, the groove part 28 along the door opening / closing direction is provided at the lower end of the sliding door 4, and the sliding door 4 moves in a state where the groove part 28 is engaged with the rocking pin 36.

本実施の形態において、操作部材５は滑車３２，３２の間に設置したブラケット３５に固定されるが、これに限定されるものではない。たとえば、戸尻側のブラケット３１上端に取り付け面を設けて、操作部材５を取り付け面に設置することもできる。これによって部品点数の削減を図ることができる。   In the present embodiment, the operation member 5 is fixed to the bracket 35 installed between the pulleys 32, 32, but is not limited thereto. For example, an operation surface can be provided on the attachment surface by providing an attachment surface at the upper end of the bracket 31 on the door bottom side. As a result, the number of parts can be reduced.

ここで、引戸４の引き込み装置の動作について説明する。図４は引戸４が開けられた状態の正面図である。引き込み部材８の係合部１６は、係合凸部２５が案内溝７ａと７ｂの立ち上がり部１２に係合して、斜めに傾斜した状態で係止される。引戸４を閉めていくと、図５に示すように操作部材５が戸先側の脚部２６に当接する。引戸４をさらに戸先側に移動すると、係合部１６は、脚部２６が操作部材５に押されて、案内溝７ａと７ｂの立ち上がり部１２および傾斜部１１から離れ、水平方向の案内溝７ａと７ｂに移動する。引き込み部材８は、操作部材５が係合部１６の脚部２６に当接した状態で戸先側に押し込まれる。   Here, operation | movement of the drawing-in apparatus of the sliding door 4 is demonstrated. FIG. 4 is a front view of the state in which the sliding door 4 is opened. The engaging portion 16 of the retracting member 8 is locked in an obliquely inclined state with the engaging convex portion 25 engaging the rising portion 12 of the guide grooves 7a and 7b. When the sliding door 4 is closed, the operation member 5 comes into contact with the leg portion 26 on the door tip side as shown in FIG. When the sliding door 4 is further moved to the door end side, the engaging portion 16 is separated from the rising portion 12 and the inclined portion 11 of the guide grooves 7a and 7b by the leg portion 26 being pushed by the operation member 5, and the horizontal direction guide groove. Move to 7a and 7b. The pull-in member 8 is pushed into the door end in a state where the operation member 5 is in contact with the leg portion 26 of the engaging portion 16.

図６に示すように、引き込み部材８のピニオンギア１３ａがラック１０ａと噛み合っており、引き込み部材８は、ピニオンギア１３ａの回転速度に応じた抵抗力を一方向性回転ダンパー１４から受ける。ピニオンギア１３ａのピッチ円直径はピニオンギア１３ｂのピッチ円直径よりも小径に形成されており、ピニオンギア１３ａの回転速度はピニオンギア１３ｂがラック１０ｂと噛み合ったときの回転速度よりも高いので、引き込み部材８が受ける抵抗力は、ピニオンギア１３ｂがラック１０ｂと噛み合ったときに受ける抵抗力よりも大きくなる。引き込み部材８は、一方向性回転ダンパー１４から抵抗力を受けて移動速度が低くなる。   As shown in FIG. 6, the pinion gear 13 a of the retracting member 8 is engaged with the rack 10 a, and the retracting member 8 receives a resistance force corresponding to the rotational speed of the pinion gear 13 a from the unidirectional rotating damper 14. The pitch circle diameter of the pinion gear 13a is formed smaller than the pitch circle diameter of the pinion gear 13b, and the rotation speed of the pinion gear 13a is higher than the rotation speed when the pinion gear 13b meshes with the rack 10b. The resistance force received by the member 8 is greater than the resistance force received when the pinion gear 13b meshes with the rack 10b. The retracting member 8 receives a resistance force from the unidirectional rotating damper 14 and moves at a low speed.

引戸４をさらに閉めていくと、ピニオンギア１３ａとラック１０ａとの噛み合いが解除され、図７および図８に示すようにピニオンギア１３ｂとラック１０ｂとが噛み合う。ピニオンギア１３ｂのピッチ円直径はピニオンギア１３ａのピッチ円直径よりも大径に形成されているで、ピニオンギア１３ｂの回転速度は、ピニオンギア１３ａがラック１０ａと噛み合ったときの回転速度よりも低くなる。引き込み部材８が受ける抵抗力は、ピニオンギア１３ａがラック１０ａと噛み合ったときに受ける抵抗力よりも小さくなるので、ピニオンギア１３ａがラック１０ａと噛み合っている場合に比して引き込み部材８の移動速度は高くなる。   When the sliding door 4 is further closed, the engagement of the pinion gear 13a and the rack 10a is released, and the pinion gear 13b and the rack 10b are engaged as shown in FIGS. Since the pitch circle diameter of the pinion gear 13b is formed larger than the pitch circle diameter of the pinion gear 13a, the rotation speed of the pinion gear 13b is lower than the rotation speed when the pinion gear 13a meshes with the rack 10a. Become. Since the resistance force received by the pull-in member 8 is smaller than the resistance force received when the pinion gear 13a meshes with the rack 10a, the moving speed of the pull-in member 8 compared to when the pinion gear 13a meshes with the rack 10a. Becomes higher.

引戸４の閉まり際では、ピニオンギア１３ｂとラック１０ｂとの噛み合いが解除されてピニオンギア１３ａ，１３ｂが回転しなくなるので、引き込み部材８は一方向性回転ダンパー１４から抵抗力を受けなくなり、さらに移動速度が高くなる。引戸４が閉め切られた状態を図１に示す。このように、引戸４を閉めていくにしたがって引き込み部材８が一方向性回転ダンパー１４から受ける抵抗力を小さくすると、たとえばパッキンが設けられる場合などに引戸４が受ける抵抗に打ち勝って引戸４を閉め切ることができる。   When the sliding door 4 is closed, the engagement between the pinion gear 13b and the rack 10b is released and the pinion gears 13a and 13b do not rotate, so that the retracting member 8 does not receive the resistance force from the unidirectional rotating damper 14 and moves further. Increases speed. A state in which the sliding door 4 is closed is shown in FIG. As described above, when the pulling member 8 receives the unidirectional rotating damper 14 from a smaller resistance as the sliding door 4 is closed, the sliding door 4 is overcome by overcoming the resistance received by the sliding door 4 when a packing is provided. Can be cut.

本実施の形態においては、ぜんまいばね１７を用いて引き込み部材８を戸先側に付勢しているので、コイルばねなどを用いた場合に比べて引き込み部材８が受ける付勢力の変化を小さくすることができる。ピッチ円直径が異なる２つのピニオンギア１３ａ，１３ｂを用いたが、これに限定されるものではなく、任意のピッチ円直径が異なる３つ以上のピニオンギアを用いることもできる。これによって引戸４を閉める場合に一方向性回転ダンパー１４から受ける抵抗力を所望の強さとして、より滑らかに引戸４を操作することができる。   In the present embodiment, the mainspring spring 17 is used to urge the retracting member 8 toward the door end, so that the change in the urging force received by the retracting member 8 is made smaller than when a coil spring or the like is used. be able to. Although two pinion gears 13a and 13b having different pitch circle diameters are used, the present invention is not limited to this, and three or more pinion gears having different pitch circle diameters may be used. Thus, when the sliding door 4 is closed, the sliding door 4 can be operated more smoothly with the resistance force received from the unidirectional rotating damper 14 as a desired strength.

また、ピニオンギア１３ｂのピッチ円直径をピニオンギア１３ａのピッチ円直径よりも小径に形成して、ピニオンギア１３ｂの回転速度をピニオンギア１３ａがラック１０ａと噛み合ったときの回転速度よりも高くすることもできる。この場合には、引戸４を閉めていくにしたがって引き込み部材８が一方向性回転ダンパー１４から受ける抵抗力が大きくなり、引戸４を静かに閉め切ることができる。   Further, the pitch circle diameter of the pinion gear 13b is formed smaller than the pitch circle diameter of the pinion gear 13a, and the rotation speed of the pinion gear 13b is made higher than the rotation speed when the pinion gear 13a meshes with the rack 10a. You can also. In this case, as the sliding door 4 is closed, the resistance force that the drawing member 8 receives from the unidirectional rotating damper 14 increases, and the sliding door 4 can be closed quietly.

閉め切った状態から引戸４を開けて戸尻側に引くと、引き込み部材８は、操作部材５が戸尻側の脚部２７に当接した状態で戸尻側に移動するが、ピニオンギア１３ａ，１３ｂは、ラック１０ａ，１０ｂと噛み合っていないので回転することはなく、一方向性回転ダンパー１４から抵抗力を受けない。さらに引戸４を戸尻側に移動すると、ピニオンギア１３ｂがラック１０ｂと噛み合ってピニオンギア１３ｂが回転するが、ピニオンギア１３ｂの回転方向は、引戸４を閉めるときの回転方向とは逆方向となるので、引き込み部材８が一方向性回転ダンパー１４から抵抗力を受けることはない。さらに引戸４が戸尻側に移動すると、ピニオンギア１３ｂとラック１０ｂと噛み合いが解除され、ピニオンギア１３ａがラック１０ａと噛み合う。ピニオンギア１３ａはラック１０ａと噛み合って回転するが、ピニオンギア１３ａの回転方向は、引戸４を閉めるときの回転方向とは逆方向となるので、引き込み部材８が一方向性回転ダンパー１４から抵抗力を受けることはない。使用者は、ぜんまいばね１７の付勢力のみに抗して引戸４を戸尻側に引くことになる。   When the sliding door 4 is opened from the closed state and pulled toward the door butt side, the retracting member 8 moves to the door butt side with the operation member 5 in contact with the leg 27 on the door butt side, but the pinion gear 13a, Since 13b is not meshed with the racks 10a and 10b, it does not rotate and does not receive a resistance force from the unidirectional rotating damper 14. When the sliding door 4 is further moved to the door bottom side, the pinion gear 13b meshes with the rack 10b and the pinion gear 13b rotates. However, the rotation direction of the pinion gear 13b is opposite to the rotation direction when the sliding door 4 is closed. Therefore, the drawing member 8 does not receive a resistance force from the unidirectional rotating damper 14. When the sliding door 4 further moves toward the door bottom, the meshing between the pinion gear 13b and the rack 10b is released, and the pinion gear 13a meshes with the rack 10a. The pinion gear 13a rotates while meshing with the rack 10a. However, since the rotation direction of the pinion gear 13a is opposite to the rotation direction when the sliding door 4 is closed, the retracting member 8 is resisted by the unidirectional rotating damper 14. Not receive. The user pulls the sliding door 4 toward the door butt side against only the urging force of the mainspring spring 17.

係合部１６の戸尻側係合凸部２５は水平方向の案内溝７ａと７ｂから傾斜部１１へ移動し、さらに傾斜部１１から立ち上がり部１２に移動する。図５に示すように引き込み部材８はこの状態で係止される。このとき係合部１６は図５の紙面に対して反時計回りに回転して戸尻側の脚部２７が斜めに傾く。操作部材５が戸尻側の脚部２７から離れ、操作部材５と係合部１６との係合が解除される。操作部材５と係合部１６との係合が解除された引戸４は、ぜんまいばね１７の付勢力を受けない状態で戸尻側に移動する。   The door bottom side engaging convex portion 25 of the engaging portion 16 moves from the horizontal guide grooves 7a and 7b to the inclined portion 11, and further moves from the inclined portion 11 to the rising portion 12. As shown in FIG. 5, the retracting member 8 is locked in this state. At this time, the engaging portion 16 rotates counterclockwise with respect to the paper surface of FIG. 5 and the door-side leg portion 27 is inclined obliquely. The operation member 5 is separated from the leg portion 27 on the door butt side, and the engagement between the operation member 5 and the engagement portion 16 is released. The sliding door 4 in which the engagement between the operation member 5 and the engaging portion 16 is released moves to the door bottom side without receiving the urging force of the mainspring spring 17.
