Description
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.
上述した技術では、次のような問題がある。すなわち、誤作動状態からの復帰に部品の変形をともなうと共に複雑な寸法設定が必要となる。
The above-mentioned technology has the following problems. That is, a complicated dimension setting is required along with the deformation of the part in returning from the malfunctioning state.

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.
