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ている。装置本体には、枠体に固定されたケーシングレールと、ケーシングレール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、ケーシングレールのラックと噛み合うピニオンギアを備え、コイルばねによって引戸の閉方向に付勢されている。ピニオンギアには回転ダンパーが連結されており、引戸が閉方向に移動するとき、ピニオンギアは回転ダンパーから抵抗力を受けて減速する。引戸が全閉位置に近付くと、ピニオンギアはラックから外れて直線部に移る。ピニオンギアが直線部に移ると、ピニオンギアは回転ダンパーからの抵抗力を受けなくなり、引戸は、コイルばねによって閉方向に付勢された状態で全閉位置まで移動する。   The sliding door retracting device described in Patent Literature 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 casing rail fixed to the frame and a retracting member that is guided by the casing rail to reciprocate. The retracting member includes a pinion gear that meshes with the rack of the casing rail, and is biased in the closing direction of the sliding door by a coil spring. A rotation damper is connected to the pinion gear, and when the sliding door moves in the closing direction, the pinion gear receives a resistance force from the rotation damper and decelerates. When the sliding door approaches the fully closed position, the pinion gear moves away from the rack and moves to the straight section. When the pinion gear moves to the linear portion, the pinion gear does not receive the resistance force from the rotary damper, and the sliding door moves to the fully closed position while being biased in the closing direction by the coil spring.

引戸の引き込み装置１の動作について説明する。引戸５が開いているときの引戸の引き込み装置１を図２（ａ）に示す。カム１１は、鉤部２５基端部がダンパー連結部材１４の切り込み３４に収容された状態で、第１係合部２３が第１案内溝１０ａに係合し、第２係合部２４が係止部１０ｃに係止されている。ダンパー連結部材１４は、係合部３９に係合した係止部材２６の係合凸部２８が第１案内溝１０ａに係合し、係合部３５が第２案内溝１０ｂに係合した状態で、カム１１の他側部側を覆うように配置されている。なお、カム１１の戸先側他側部は面取りされているので、カム１１の第２係合部２４が係止部１０ｃに係止されたとき、カム１１がダンパー連結部材１４と接触することを防止することができる。   The operation of the sliding door retracting apparatus 1 will be described. FIG. 2A shows the sliding door retracting device 1 when the sliding door 5 is open. In the cam 11, the first engagement portion 23 is engaged with the first guide groove 10 a and the second engagement portion 24 is engaged with the base end portion of the flange portion 25 being accommodated in the notch 34 of the damper connecting member 14. Locked to the stop 10c. In the damper connecting member 14, the engagement convex portion 28 of the locking member 26 engaged with the engagement portion 39 is engaged with the first guide groove 10 a, and the engagement portion 35 is engaged with the second guide groove 10 b. Therefore, it arrange | positions so that the other side part side of the cam 11 may be covered. Since the other end of the cam 11 is chamfered, the cam 11 comes into contact with the damper connecting member 14 when the second engagement portion 24 of the cam 11 is locked to the locking portion 10c. Can be prevented.

戸尻側に位置している装置本体４が引戸５とともに閉方向に移動すると、カム１１の凸部２０が、操作部材７に当接する。カム１１は、第２係合部２４が係止部１０ｃに係止されて戸先側が他側部側に傾いているので、戸先側の凸部２１が操作部材７に当接することが防止される。凸部２０が操作部材７に当接してカム１１が戸尻側に押圧されると、第２係合部２４が係止部１０ｃから抜け出て第２案内溝１０ｂに移動する。   When the apparatus main body 4 located on the door bottom side moves in the closing direction together with the sliding door 5, the convex portion 20 of the cam 11 comes into contact with the operation member 7. In the cam 11, the second engagement portion 24 is engaged with the engagement portion 10 c and the door end side is inclined toward the other side portion, so that the protrusion 21 on the door end side is prevented from coming into contact with the operation member 7. Is done. When the convex portion 20 comes into contact with the operation member 7 and the cam 11 is pressed toward the door bottom, the second engagement portion 24 comes out of the locking portion 10c and moves to the second guide groove 10b.

図２（ｂ）に示すように、カム１１が係止部１０ｃから抜け出ると、閉方向に移動する装置本体４には、引っ張りコイルばね１２の付勢力が閉方向に働く。カム１１の戸尻側端面４０がダンパー連結部材１４の立ち上がり部３２を押圧し、ダンパー連結部材１４に係合したダンパー９のロッド１３を戸尻側に押すので、装置本体４はダンパー９から抵抗力を受けながら戸先側に移動する。引戸５は、ダンパー９の抵抗力によって、戸先側に移動するにしたがって減速される。ダンパー９として直動タイプのものが用いられているので、勢い良く引戸５が閉められた場合であっても引戸５を確実に減速させることができる。本実施の形態ではエアダンパーを用いているが、これに限定されるものではなくオイルダンパーを用いることもできる。   As shown in FIG. 2B, when the cam 11 comes out of the locking portion 10c, the urging force of the tension coil spring 12 acts in the closing direction on the device body 4 that moves in the closing direction. Since the door bottom side end surface 40 of the cam 11 presses the rising portion 32 of the damper connecting member 14 and pushes the rod 13 of the damper 9 engaged with the damper connecting member 14 to the door bottom side, the apparatus main body 4 resists from the damper 9. Move to the doorside while receiving force. The sliding door 5 is decelerated as it moves to the door end side by the resistance force of the damper 9. Since the damper 9 is a direct-acting type, the sliding door 5 can be surely decelerated even when the sliding door 5 is vigorously closed. Although the air damper is used in the present embodiment, the present invention is not limited to this, and an oil damper can also be used.

装置本体４がさらに戸先側に移動すると、ダンパー連結部材１４の係合部３５は、第２案内溝１０ｂから離れて、図２（ｃ）に示すように係止部１０ｄに係止される。係合部３５が係止部１０ｄに係止されると、ダンパー連結部材１４は戸尻側が他側部側に傾く。立ち上がり部３２が他側部側に移動するので、カム１１はダンパー連結部材１４から離れる。カム１１は、ダンパー連結部材１４から離れるとダンパー９から抵抗力を受けなくなる。装置本体４は、引っ張りコイルばね１２によって戸先側に付勢された状態で引戸の全閉位置まで移動するので、引戸５を完全に閉め切ることができる。   When the apparatus main body 4 further moves to the door end side, the engaging portion 35 of the damper connecting member 14 moves away from the second guide groove 10b and is locked to the locking portion 10d as shown in FIG. . When the engaging portion 35 is locked to the locking portion 10d, the door connecting side of the damper connecting member 14 is inclined to the other side portion side. Since the rising portion 32 moves to the other side, the cam 11 is separated from the damper connecting member 14. When the cam 11 is separated from the damper connecting member 14, it receives no resistance from the damper 9. Since the apparatus body 4 moves to the fully closed position of the sliding door while being biased toward the door end side by the tension coil spring 12, the sliding door 5 can be completely closed.

全閉位置にある引戸５を開ける場合には、引っ張りコイルばね１２の付勢力に抗して引戸５を開方向に移動させる。装置本体４が開方向に移動して、係止部１０ｄに係止されているダンパー連結部材１４の切り込み３４にカム１１の鉤部２５基端部が収容されるとともに、ダンパー連結部材１４の立ち上がり部３３がカム１１の戸先側端面４１に当接する。引戸５をさらに開方向に移動すると、ダンパー連結部材１４の係合部３５が係止部１０ｄから抜け出て第２案内溝１０ｂに移動する。装置本体４は、ダンパー連結部材１４の立ち上がり部３３がカム１１の戸先側端面４１に当接した状態で開方向に移動する。このときダンパー９の抵抗力は生じない。カム１１の第２係合部２４は第２案内溝１０ｂから離れて係止部１０ｃに移動する。第２係合部２４が係止部１０ｃに係止されると、カム１１は戸先側が斜めに傾き、凸部２１は操作部材７から離れて引戸５とともに戸尻側に移動する。本実施の形態では、引戸５側に装置本体４が設けられ、上枠２側に操作部材７が設けられているが、これに限定されるものではなく、引戸５側に操作部材７を設け、上枠２側に装置本体４を設けることもできる。   When opening the sliding door 5 in the fully closed position, the sliding door 5 is moved in the opening direction against the urging force of the tension coil spring 12. The apparatus main body 4 moves in the opening direction so that the base end portion of the flange portion 25 of the cam 11 is accommodated in the notch 34 of the damper connecting member 14 locked to the locking portion 10d, and the damper connecting member 14 rises. The part 33 contacts the door end side surface 41 of the cam 11. When the sliding door 5 is further moved in the opening direction, the engaging portion 35 of the damper connecting member 14 comes out of the locking portion 10d and moves to the second guide groove 10b. The apparatus main body 4 moves in the opening direction in a state where the rising portion 33 of the damper connecting member 14 is in contact with the door end side end surface 41 of the cam 11. At this time, the resistance force of the damper 9 is not generated. The second engaging portion 24 of the cam 11 moves away from the second guide groove 10b to the locking portion 10c. When the second engaging portion 24 is locked to the locking portion 10 c, the cam 11 tilts obliquely on the door end side, and the convex portion 21 moves away from the operation member 7 and moves to the door bottom side together with the sliding door 5. In the present embodiment, the apparatus main body 4 is provided on the sliding door 5 side and the operation member 7 is provided on the upper frame 2 side. However, the present invention is not limited to this, and the operation member 7 is provided on the sliding door 5 side. The apparatus main body 4 can also be provided on the upper frame 2 side.

The apparatus main body 4 includes a casing 8 fixed to the sliding door 5; A linear motion type damper 9 attached to the casing 8, a cam 11 that moves along a guide groove 10 that is a guide portion of the casing 8 while being engaged with the operation member 7, and a sliding door 5 in which the apparatus main body 4 is installed. A damper coupling member that receives a resistance force from the damper 9 is connected to the tension coil spring 12 that is an urging means that urges the rod in the closing direction and the rod 13 of the damper 9 and is pressed by the cam 11 that is engaged with the operation member 7. When the sliding door 5 moves in the closing direction, the cam 11 is engaged with the operation member 7 in a state of being locked to the locking portion 10c that is the first locking portion provided continuously to the guide groove 10. Engaging and locking part 10c The damper connecting member 14 is pulled out and engaged with the guide groove 10 to press the damper connecting member 14, and the damper connecting member 14 is engaged with the engaging portion 10 d which is the second engaging portion provided in the vicinity of the sliding door 5 fully closed position of the guide groove 10. When locked, the device body 4 moves away from the damper connecting member 14 and receives only the urging force of the tension coil spring 12 and moves to the fully closed position of the sliding door 5, so that the sliding door 5 can be sufficiently decelerated when closed, The sliding door 5 can be completely closed.

さらに、引戸５は引戸５の閉方向に向かって下降傾斜したレール３に支持されているので、操作者が引戸５を閉方向に移動しなくても係止部１０ｃに係止したカム１１を操作部材７に当接させ、カム１１を係止部１０ｃから案内溝１０へ押し出すことができる。   Furthermore, since the sliding door 5 is supported by the rail 3 inclined downward in the closing direction of the sliding door 5, the cam 11 locked to the locking portion 10c is not required even if the operator does not move the sliding door 5 in the closing direction. The cam 11 can be pushed out from the locking portion 10c into the guide groove 10 by being brought into contact with the operation member 7.
