Description

可動体のアシスト装置Movable assist device
　本発明は、各種の可動体の動作を補助する可動体のアシスト装置に関する。 The present invention relates to a movable body assist device that assists the operation of various movable bodies.
　戸枠などの支持体に対して相対移動する吊り戸や引き戸等の可動体の動作を補助するため、付勢機構を用いて強制移動をする可動体のアシスト装置が知られている。このような可動体のアシスト装置では、例えば戸枠側に当受体が設けられ、吊り戸側に当受体に係合可能な当接体が設けられている。当接体は待機位置と引き込み位置でスライド移動可能であり、付勢機構としての引張りコイルばねに連結されている。当接体は例えば先端に樹脂製の係合部を有し、この係合部が当受体と係合及び係合解除可能になっている。 In order to assist the operation of a movable body such as a sliding door or a sliding door that moves relative to a support such as a door frame, a movable body assist device that uses a biasing mechanism to forcibly move is known. In such a movable body assist device, for example, a receiving body is provided on the door frame side, and a contact body that can be engaged with the receiving body is provided on the hanging door side. The contact body is slidable at the standby position and the retracted position, and is connected to a tension coil spring as an urging mechanism. The contact body has, for example, a resin engaging portion at the tip, and this engaging portion can be engaged with and released from the receiving body.
　吊り戸が閉めきられていない開位置にあるとき、当接体は、引張りコイルばねを引き伸ばした状態で待機位置に保持されている。開位置から操作者が吊り戸を閉位置（移動終了位置）に移動させると、その途中で当接体が、当受体に突き当たり、当受体を捕捉する。同時に、待機位置での保持が解かれ、当接体が当受体を捕捉したまま引張りコイルばねに引張られて引込位置に向かって移動する。このため、この移動寸法の分吊り戸が強制的に移動終了位置に向かって移動させられる。 When the suspension door is in the open position where it is not closed, the contact body is held at the standby position with the tension coil spring extended. When the operator moves the suspension door from the open position to the closed position (movement end position), the abutting body hits the receiving body and captures the receiving body. At the same time, the holding at the standby position is released, and the abutment body is pulled by the tension coil spring while moving to the retracted position while capturing the receiving body. For this reason, the suspension door of this moving dimension is forcibly moved toward the movement end position.
　吊り戸が閉位置にあるとき、当接体は、引張りコイルばねを圧縮した状態となっている。この閉位置から操作者が吊り戸を開位置に向けて移動させると、引張りコイルばねを引張りながら吊り戸が移動する。所定位置に至ると当接体が当受体を開放し、再び待機位置へ保持される。 When the suspension door is in the closed position, the contact body is in a state where the tension coil spring is compressed. When the operator moves the suspension door from the closed position toward the open position, the suspension door moves while pulling the tension coil spring. When the predetermined position is reached, the contact body opens the receiving body and is held at the standby position again.
　このような可動体のアシスト装置では、誤作動により当接体が当受体に係合しないまま当接体が引込位置に位置する状態となる場合がある。この状態から復帰させる機構として、当接体に斜めのガイド面を設け、当受体との当接により当受体から退避する下向きに圧力を作用させて回動することにより当受体と当接体とを係合させることが行われている（例えば特許文献１参照）。このアシスト装置では、当接体は軸を中心として回動することで当受体に再係合する所定の形状に構成され、当接体を収容した枠体が下向きに弾性変形するように形成され、かつ、枠体の変形を許容する隙間が設けられている。 In such a movable body assist device, the contact body may be in the retracted position without being engaged with the receiving body due to a malfunction. As a mechanism for returning from this state, the contact body is provided with an oblique guide surface, and is rotated by applying a downward pressure to retract from the contact body by contact with the contact body. Engagement with a contact body is performed (for example, refer patent document 1). In this assist device, the contact body is configured to have a predetermined shape that re-engages with the receiving body by rotating about the axis, and the frame body that houses the contact body is elastically deformed downward. In addition, a gap allowing deformation of the frame is provided.

　第２の付勢機構である引張コイルばね３４は前端部がフック３３の第２付勢部３３ｃに連結され、後端部がラッチベース３１の下部の連結部３１ｄに連結されている。この引張コイルばね３４はフック３３を常時Ｒ４方向に付勢する機能と、第２軸部３３ａを待機路２７ｂに引っかけることによりラッチ２２を待機位置に保持させる機能と、を有している。 The tension coil spring 34, which is the second urging mechanism, has a front end connected to the second urging portion 33c of the hook 33 and a rear end connected to a connecting portion 31d at the bottom of the latch base 31. The tension coil spring 34 has a function of constantly urging the hook 33 in the R4 direction and a function of holding the latch 22 in the standby position by hooking the second shaft portion 33a on the standby path 27b.
　制動機構としてのピストンダンパ２４は、ハウジング２１内の上部において、軸方向がスライド方向に沿うように配置されている。ピストンダンパ２４は、内部に流体が封入されたシリンダ５１と、シリンダ５１内でスライド方向に往復動するピストンを先端に有するピストンロッド５２とを有している。 The piston damper 24 as a braking mechanism is arranged in the upper part in the housing 21 so that the axial direction is along the sliding direction. The piston damper 24 includes a cylinder 51 in which a fluid is sealed, and a piston rod 52 having a piston that reciprocates in the sliding direction in the cylinder 51 at the tip.

The sliding movement of the latch 22 with respect to the housing 21 is braked. The fluid sealed in the cylinder 51 is typically a viscous fluid such as silicone oil, but is not limited thereto, and a gas may be used.
　以下、本実施形態にかかるアシスト装置１の動作について図８及び図９を参照して説明する。 Hereinafter, the operation of the assist device 1 according to the present embodiment will be described with reference to FIGS. 8 and 9.
　まず、第１状態から第２状態とする第１の動作について図８を参照して説明する。図８の＜ＳＴ１＞に示すように、ラッチ２２がストライカ１０に到達していない第１状態では、引張りコイルばね２３を引き伸ばした状態であり、ラッチ２２はハウジング２１の端部の待機位置に保持されている。このとき、ラッチ２２の第２軸部３３ａが待機路２７ｂに引っかかり引張コイルばね３４によって引っ張られて保持されている。 First, the first operation from the first state to the second state will be described with reference to FIG. As shown in <ST1> of FIG. 8, in the first state where the latch 22 does not reach the striker 10, the tension coil spring 23 is extended, and the latch 22 is held at the standby position at the end of the housing 21. Has been. At this time, the second shaft portion 33a of the latch 22 is hooked on the standby path 27b and pulled and held by the tension coil spring 34.
　第１状態から操作者が吊り戸１１０を戸先側（第１方向）に向かって移動させることにより、＜ＳＴ２＞に示すように吊り戸１１０が第１の所定位置に至ると、ラッチ２２がストライカ１０に当接する。すると、ストライカ１０の押圧面１４ｂが被押圧部３２ｃを後方に押し込むことにより、第１軸部３２ｂを中心としてカム３２がＲ１方向に回動する。 When the operator moves the suspension door 110 from the first state toward the door end side (first direction), when the suspension door 110 reaches the first predetermined position as shown in <ST2>, the latch 22 is It contacts the striker 10. Then, when the pressing surface 14b of the striker 10 pushes the pressed portion 32c backward, the cam 32 rotates in the R1 direction around the first shaft portion 32b.
　この回動によって、＜ＳＴ３＞に示すように、カム３２の先端のフック３３がストライカ１０に係合し、ラッチ２２にストライカ１０が捕捉される。このとき、カム３２の一対の係合片３３ｂと被押圧部３２ｃとの間であってアーム部３２ｅ上の空間に係合突起１２が配置され、第１係合面１３ａが係合片３３ｂの後側の係合面３３ｅに対向する。 By this rotation, the hook 33 at the tip of the cam 32 is engaged with the striker 10 and the striker 10 is captured by the latch 22 as shown in <ST3>. At this time, the engagement protrusion 12 is arranged in the space between the pair of engagement pieces 33b of the cam 32 and the pressed portion 32c and on the arm portion 32e, and the first engagement surface 13a is the engagement piece 33b. Opposite the rear engagement surface 33e.
　また、カム３２がＲ１方向に回動すると同時に下方の第２軸部３３ａが上方に移動して主ガイド路２７ａに入り込む位置に至り、待機路２７ｂへの保持が解除されるとともに、ラッチ２２がスライド方向（Ｘ方向）に沿って移動可能な状態となる。 At the same time as the cam 32 rotates in the R1 direction, the lower second shaft portion 33a moves upward to enter the main guide path 27a, the holding to the standby path 27b is released, and the latch 22 is It will be in the state which can move along a slide direction (X direction).
　そして、＜ＳＴ４＞に示すように、引張コイルばね２３の復元力により引張りコイルばね２３を圧縮させながら、ハウジング２１及び吊り戸１１０に対して右方にラッチ２２が相対移動して引込位置（第２位置）まで相対移動させられる。この移動に伴い戸枠１００及びストライカ１０に対して吊り戸１１０及びハウジング２１が第１方向に相対的に強制移動させられる。このときピストンダンパ２４により抵抗力が付与され、緩衝しながらゆっくり自動的に吊り戸１１０が閉まる方向に移動することとなる。 Then, as shown in <ST4>, while the tension coil spring 23 is compressed by the restoring force of the tension coil spring 23, the latch 22 moves relative to the housing 21 and the suspension door 110 to the right and the retracted position (the first position) 2 position). With this movement, the suspension door 110 and the housing 21 are forcibly moved relative to the door frame 100 and the striker 10 in the first direction. At this time, a resistance force is applied by the piston damper 24, and the suspension door 110 moves slowly and automatically in the direction of closing while buffering.
　次に、第２状態から第１状態とする第２の動作について図８を参照して説明する。この第２の動作では上記第１の動作と逆に＜ＳＴ４＞＜ＳＴ３＞＜ＳＴ２＞＜ＳＴ１＞の順で動作する。すなわち、＜ＳＴ４＞に示すように吊り戸１１０が戸先側の終了位置に移動し切った第２状態から吊り戸１１０を戸尻側（第２方向）に移動させる操作をすると、引張コイルばね２３の付勢力に抗してラッチ２２がストライカ１０を捕捉したまま吊り戸１１０及びハウジング２１に対して一端側に相対移動しながら、吊り戸１１０が右側に移動する＜ＳＴ３＞。このとき、ラッチ２２の後端はピストンダンパ２４のピストンロッド５２に連結されているため、ピストンを移動させつつシリンダ５１内の流体の抵抗力を受ける。 Next, the second operation from the second state to the first state will be described with reference to FIG. In the second operation, the operation is performed in the order of <ST4> <ST3> <ST2> <ST1> contrary to the first operation. That is, as shown in <ST4>, when the operation is performed to move the suspension door 110 from the second state where the suspension door 110 has moved to the end position on the door end side to the door bottom side (second direction), the tension coil spring The suspension door 110 moves to the right side while moving relative to the suspension door 110 and the housing 21 to one end side while the latch 22 captures the striker 10 against the urging force of 23 <ST3>. At this time, since the rear end of the latch 22 is connected to the piston rod 52 of the piston damper 24, it receives the resistance force of the fluid in the cylinder 51 while moving the piston.
　所定位置に至ると、被押圧部３２ｃからストライカ１０が離れて引張りコイルばね４１の復元力により第２軸部３３ａを中心としてカム３２がＲ２方向に回動する＜ＳＴ２＞。この回動によりストライカ１０が解放され、フック３３とストライカ１０との係合が解除される。同時に第２軸部３３ａは主ガイド路２７ａの前端の待機位置に至り、第２軸部３３ａが下方の待機路２７ｂに入り込むとともに、引張りコイルばね３４により再び待機位置に保持される待機状態に戻る＜ＳＴ１＞。この後、吊り戸１１０の移動は引張コイルばね２３の付勢力から開放される。 When the predetermined position is reached, the striker 10 is separated from the pressed portion 32c, and the cam 32 rotates in the R2 direction around the second shaft portion 33a by the restoring force of the tension coil spring 41 <ST2>. By this rotation, the striker 10 is released, and the engagement between the hook 33 and the striker 10 is released. At the same time, the second shaft portion 33a reaches the standby position at the front end of the main guide path 27a, the second shaft portion 33a enters the lower standby path 27b, and returns to the standby state where it is held again at the standby position by the tension coil spring 34. <ST1>. Thereafter, the movement of the suspension door 110 is released from the urging force of the tension coil spring 23.
　次に、第３の動作として、例えば誤作動等によりラッチ２２がストライカ１０に係合しないまま引込位置に移動してしまった第３の状態からの復帰動作について、図９を参照して説明する。 Next, as a third operation, a return operation from the third state in which the latch 22 has moved to the retracted position without being engaged with the striker 10 due to a malfunction or the like will be described with reference to FIG. .
＜ＳＴ５＞に示すように、誤作動によりストライカ１０との係合が解除された状態でラッチ２２が引込位置にある第３の状態から、吊り戸１１０が戸枠１００に対して第１方向に移動すると、＜ＳＴ６＞に示すように、フック３３がストライカ１０に当接し、係合片３３ｂが押圧面１４ｂによって後方に押圧される。この押圧により、＜ＳＴ７＞に示すようにフック３３は、第２軸部３３ａを中心として、Ｒ３方向に揺動する。この揺動により、フック３３の係合片３３ｂの上端部が第２状態よりも下方に移動しストライカの通過経路から退避することで、ストライカ１０がフック３３を乗越え可能となり、Ｘ方向に沿って移動可能となる。このとき、係合片３３ｂの前面がテーパ面３３ｄとなっていることにより、乗り越えがスムーズかつ容易となる。この状態で、吊り戸１１０が戸枠１００に対して第１方向に移動することでストライカ１０と係合片３３ｂとが係合可能な位置まで引込方向に移動する。 As shown in <ST5>, the suspension door 110 moves in the first direction with respect to the door frame 100 from the third state in which the latch 22 is in the retracted position with the engagement with the striker 10 released due to a malfunction. When moved, as shown in <ST6>, the hook 33 comes into contact with the striker 10, and the engaging piece 33b is pressed backward by the pressing surface 14b. By this pressing, as shown in <ST7>, the hook 33 swings in the R3 direction about the second shaft portion 33a. By this swinging, the upper end portion of the engagement piece 33b of the hook 33 moves downward from the second state and retreats from the striker passage path, so that the striker 10 can get over the hook 33 and extend along the X direction. It becomes possible to move. At this time, since the front surface of the engagement piece 33b is a tapered surface 33d, the overcoming is smooth and easy. In this state, the suspension door 110 moves in the first direction with respect to the door frame 100, so that the striker 10 and the engagement piece 33b move in the pull-in direction to a position where the striker 10 and the engagement piece 33b can engage with each other.
　ストライカ１０の第２の係合部１４が係合片３３ｂを乗越えると、＜ＳＴ８＞に示すように引張りコイルばね３４の復元力によりフック３３がＲ４方向に揺動する。この揺動により、係合片３３ｂが通過経路に進入して連結部１５の脇に進入することで、ストライカ１０とラッチ２２が係合する。このとき第２の係合部１４の係合面１４ａと係合片３３ｂの後側の係合面３３ｅとが対向して係合するため、第１係合面１４ａに係合する第２状態よりも後方位置で係合することになる。 When the second engagement portion 14 of the striker 10 gets over the engagement piece 33b, the hook 33 swings in the R4 direction by the restoring force of the tension coil spring 34 as shown in <ST8>. By this swinging, the engagement piece 33b enters the passage path and enters the side of the connecting portion 15, whereby the striker 10 and the latch 22 are engaged. At this time, since the engagement surface 14a of the second engagement portion 14 and the engagement surface 33e on the rear side of the engagement piece 33b are engaged with each other, the second state of engaging with the first engagement surface 14a. It will engage at a rear position.
　この係合状態で吊り戸１１０を第２方向（移動終了位置側から離間する方向）に移動させると、＜ＳＴ９＞に示すように、ストライカ１０がラッチ２２に捕捉された状態で、主ガイド路２７ａに沿って移動する。そして第１位置に至ると、カム３２が回動して待機路２７ｂに保持されるとともにストライカ１０とラッチ２２との係合が解除され、前記第１の状態に復帰する。 When the suspension door 110 is moved in the second direction (a direction away from the movement end position) in this engaged state, the main guide path is in a state where the striker 10 is captured by the latch 22 as shown in <ST9>. Move along 27a. When the first position is reached, the cam 32 is rotated and held in the standby path 27b, and the engagement between the striker 10 and the latch 22 is released, and the first state is restored.
　本実施形態によれば、誤動作状態からの復帰を可能とするとともに部品の破損を回避できる。すなわち、ラッチ２２を移動経路から下方に退避させるように揺動可能としたことにより、第３の状態から第１の状態への復帰が可能となる。また、フック３３を揺動する構成としたことにより、高さ寸法の許容範囲が大きく、寸法設定が容易である。また、この退避によりストライカ１０とラッチ２２とが衝突を防ぎ破損を回避することが可能である。また、自動復帰の際に部品を弾性変形させる必要がないため、弾性樹脂疲労等による部品の破損を防止でき、長期間性能を保つことが出来る。 According to this embodiment, it is possible to return from a malfunctioning state and to avoid damage to parts. That is, since the latch 22 can be swung so as to be retracted downward from the movement path, it is possible to return from the third state to the first state. Further, since the hook 33 is configured to swing, the allowable range of the height dimension is large, and the dimension setting is easy. Further, by this retraction, the striker 10 and the latch 22 can be prevented from colliding and avoiding damage. Further, since it is not necessary to elastically deform the component at the time of automatic return, it is possible to prevent the component from being damaged due to elastic resin fatigue or the like, and to maintain the performance for a long time.
　ラッチ２２を２段階に回転可能な構造として１つのガイドレール２７内を移動するだけの単純な構成で、複数の異なる動作をすることが可能となる。 It is possible to perform a plurality of different operations with a simple configuration in which the latch 22 is structured to be rotatable in two stages and only moves within one guide rail 27.
　さらに、ストライカ１０の前後２箇所に係合部１３，１４を設けるとともにその間の連結部１５の脇に係合片３３ｂを進入可能とする形状により、正常状態での動作の安定性を確保しながら、誤作動復帰時の揺動寸法を小さく設定できる。このため装置の小型化を図れる。 Further, the engagement portions 13 and 14 are provided at two positions before and after the striker 10 and the engagement piece 33b can enter the side of the connecting portion 15 between them while ensuring the stability of the operation in the normal state. , The swing dimension at the time of malfunction return can be set small. For this reason, the size of the apparatus can be reduced.

　上記実施形態では、ハウジング２１の一方側のみにラッチ２２が設けられ、一方向のアシスト動作を行う場合を例示したが、これに限られるものではない。例えば図１０に示すようにハウジング２１の両端にラッチ２２を設けるとともに戸枠１００の左右両側にストライカ１０をそれぞれ設けることにより、戸先側及び戸尻側の両方向の動作をアシストする構成としてもよい。場合には例えば引張コイルばね２３の両端をそれぞれ両側のラッチ２２に連結するとともに、ピストンダンパ２４のシリンダ５１とピストンロッド５２の端部をそれぞれ両側のラッチベース３１にそれぞれ連結することにより、両側のラッチ２２の補助及び制動に共通の機構を利用することができる。 In the above embodiment, the latch 22 is provided only on one side of the housing 21 and the one-way assist operation is performed. However, the present invention is not limited to this. For example, as shown in FIG. 10, it is good also as a structure which assists the operation | movement of the both directions of a door tip side and a door bottom side by providing the latch 22 in both ends of the housing 21, and providing the striker 10 in the both right and left sides of the door frame 100, respectively. . In this case, for example, both ends of the tension coil spring 23 are connected to the latches 22 on both sides, and the ends of the cylinder 51 and the piston rod 52 of the piston damper 24 are connected to the latch bases 31 on both sides, respectively. A common mechanism for assisting and braking the latch 22 can be used.
　また、第１の付勢手段と第２の付勢手段として個別の引張コイルばね２３，３４を設けた例を示したが、これに限られるものではなく、一つの付勢機構でこれらの複数の異なる機能を兼ねるように構成してもよい。 Moreover, although the example which provided the separate tension | pulling coil springs 23 and 34 as a 1st urging | biasing means and a 2nd urging | biasing means was shown, it is not restricted to this, One of these urging mechanisms is a plurality of these You may comprise so that it may serve as a different function.
　なお、本実施形態においては、正常時用と誤作動復帰時用とで異なる位置に係合する場合を例示したが、正常時用と誤作動復帰時用とで同じ位置に係合するようにしてもよい。この場合であっても上記実施形態と同様に通過経路から退避させることにより再係合可能となる。 In the present embodiment, the case of engaging at different positions for normal use and for returning from malfunction has been illustrated, but the same position should be engaged for normal use and for returning from malfunction. May be. Even in this case, it is possible to re-engage by retracting from the passage route as in the above embodiment.
　上記実施形態においては一枚の吊り戸１１０に着目して説明したが、実際には同様の吊り戸１１０及びアシストユニット２０が２以上備えられている場合にも本発明を適用できる。 In the above embodiment, the description has been given focusing on one suspension door 110, but the present invention can also be applied to the case where two or more similar suspension doors 110 and two or more assist units 20 are actually provided.
　さらに上記実施形態においてはフック３３を退避方向に付勢する第２の付勢手段として引っ張りコイルばね３４を用いたが、これに限られるものではなく、他の構造の付勢手段を用いてもよい。 Further, in the above embodiment, the tension coil spring 34 is used as the second urging means for urging the hook 33 in the retracting direction. However, the present invention is not limited to this, and urging means having another structure may be used. Good.
　また、フック３３が揺動により進退移動する構成について例示したが、これに限られるものではなく、例えばスライド方向と交差する方向に移動することで進退動する構造を用いても良い。例えば図１１に示すように圧縮コイルばね１３４を用いてカム３２の先端でフック１３３を上下方向に移動可能とすることで通過経路に対する進退移動可能とする構成も適用可能である。この場合にも先端側の面をテーパ状の傾斜面１３３ａとすることにより、傾斜面１３３ａがストライカ１０によって後方に押圧されることでフック１３３が下方に移動して通過経路から退避可能となる。ストライカ１０の移動後は圧縮コイルばね１３４の復元力によって上方に移動させられることにより通過経路に復帰してストライカ１０と係合可能となる。この他、付勢手段として例えば板ばねやねじりコイルばねなどを用いてもよい。 In addition, the configuration in which the hook 33 moves back and forth by swinging is illustrated, but the present invention is not limited to this. For example, a structure that moves forward and backward by moving in the direction intersecting the slide direction may be used. For example, as shown in FIG. 11, a configuration in which the hook 133 can be moved in the vertical direction at the tip of the cam 32 by using a compression coil spring 134 to be able to move forward and backward with respect to the passage route is also applicable. Also in this case, by making the tip-side surface into a tapered inclined surface 133a, the inclined surface 133a is pushed backward by the striker 10 so that the hook 133 moves downward and can be retracted from the passage route. After the striker 10 is moved, the striker 10 is moved upward by the restoring force of the compression coil spring 134 to return to the passage path so that the striker 10 can be engaged. In addition, for example, a plate spring or a torsion coil spring may be used as the biasing means.
