Abstract

PROBLEM TO BE SOLVED: To provide an opening/closing device which has achieved both a pop-up mechanism which allows a door body to automatically jump out, and a catch mechanism which decelerates a moving speed of the door body and holds the door body so that the door body which has moved to a door end side does not return.SOLUTION: An opening/closing device 1 which is used for a sliding door 100 movable along the longer direction of an upper frame 41 has, at the upper frame 41, a catch mechanism which energizes the sliding door 100 by a spring 14 by the movement of the sliding door 100 in the opening direction and which holds the sliding door 100 at a predetermined position in a state where the spring 14 is energized. In the opening/closing device 1, the catch mechanism releases the holding of the sliding door 100 by the further movement of the sliding door 100 into an opening direction from the predetermined position of the sliding door 100.SELECTED DRAWING: Figure 6

Description

本発明は、開閉装置に関する。   The present invention relates to an opening / closing device.

従来、引戸の中には、戸袋に戸体が納まる引込戸タイプが存在する。引込戸は、通常の開閉操作で戸体を戸袋に納めることは容易だが、引込戸を閉める際には戸袋から戸体を引っ張り出す必要があり、開閉操作に手間がかかる。このため、引込戸が戸袋から自動的に飛び出し、その後使用者が戸体に手をかけて引込戸を閉められるようにした「ポップアップ機能」を備えた引込戸が知られている（例えば、特許文献１参照）。   Conventionally, there is a retractable door type in which a door is housed in a door pocket. Although it is easy for the retractable door to store the door body in the door pocket by a normal opening / closing operation, it is necessary to pull out the door body from the door pocket when closing the retractable door, which takes time and effort. For this reason, a retractable door having a “pop-up function” that allows the retractable door to automatically pop out of the door pocket and then the user to close the retractable door by placing a hand on the door (for example, patents) is known. Reference 1).

引戸は、開くときに戸体の移動速度を減衰させないと、戸先側の端部が跳ね返って戸体が戻ることがある。このため、戸体の戸先が引戸の戸先側端部に到達する間際に、戸体の速度を適正に減速させて、戸体が戻らず引戸が完全に開くように手を添える必要がある。そこで、戸体が引戸の戸先側端部に到達する前に、移動速度を減速させる緩衝ダンパを戸体に設けたり（例えば、特許文献２参照）、戸体を捕捉する捕捉部材を設けたりすることで（例えば、特許文献３参照）、戸体の移動速度を減衰させる減衰機構を備える開閉装置が提案されている。   When the sliding door is opened, if the moving speed of the door is not attenuated, the end of the door tip may bounce back and the door may return. For this reason, it is necessary to appropriately reduce the speed of the door body just before the door end of the sliding door reaches the door end side of the sliding door, and to attach the hand so that the door does not return and the sliding door opens completely. is there. Therefore, before the door body reaches the door end side end of the sliding door, a buffer damper for reducing the moving speed is provided on the door body (for example, see Patent Document 2), or a capturing member for capturing the door body is provided. By doing so (for example, refer patent document 3), the switchgear provided with the damping mechanism which attenuates the moving speed of a door is proposed.

特開２０１２−７３３２号公報JP 2012-7332 A 特開２００９−１２７２９３号公報JP 2009-127293 A 特開２０１３−１７０４１５号公報JP 2013-170415 A

特許文献２や３のような減衰機構を備えた引戸では、戸体を戸先側へ移動させて引き戸を開ける操作はスムーズだが、引戸を戸尻側へ移動させて閉める際には、減衰機構を解除する必要が生じる。このため、引戸を戸尻側へ引き出す際、最初に通常の操作よりも力が必要となる。また、戸体を戸袋に納める引込戸においては、戸を戸袋から引き出す際に、戸袋が邪魔して通常の引戸のように減衰機構を解除できないので、特許文献２や３のような減衰機構を搭載することはできない。   In the sliding door provided with the damping mechanism as in Patent Documents 2 and 3, the operation of moving the door body to the door end side and opening the sliding door is smooth, but when the sliding door is moved to the door bottom side and closed, the damping mechanism Need to be released. For this reason, when pulling out the sliding door to the door bottom side, first, a force is required rather than a normal operation. Further, in a retractable door that houses the door in the door pocket, when the door is pulled out of the door pocket, the door pocket interferes and the damping mechanism cannot be released like a normal sliding door. It cannot be installed.

また、減衰機構の設けられた引戸と、戸袋に戸体を納める引込戸とが混在する住居の場合は、減衰機構の設けられた引戸の操作感覚で、減衰機構の設けられていない引込戸の開閉操作をしてしまうことが考えられる。この場合、使用者が勢いよく引込戸を操作することにより戸の跳ね返りによるケガや戸体の破損が懸念される。また、ポップアップ機能を備えた引込戸では、強い衝撃によりポップアップ機能が設けられた部品の破損の恐れがある。   In addition, in the case of a residence where a sliding door provided with a damping mechanism and a sliding door that houses a door in a door pocket are mixed, the operating feeling of the sliding door provided with the damping mechanism is similar to that of a retracting door that is not provided with a damping mechanism. It may be possible to open and close. In this case, there is a concern that injury or damage to the door body due to rebounding of the door by the user operating the retractable door vigorously. Moreover, in the retractable door provided with the pop-up function, there is a risk of damage to the parts provided with the pop-up function due to a strong impact.

このため、戸体を自動的に飛び出させるポップアップ機構と、戸先側へ移動した戸体が戻らないように、戸体の移動速度を減速させて戸体を保持するキャッチ機構とが両立した開閉装置が望まれていた。   Therefore, the pop-up mechanism that automatically pops out the door and the catch mechanism that holds the door by decelerating the moving speed of the door so that the door moved to the door end does not return. A device was desired.

ハートカム溝２０は、溝内に傾斜面及び段差２６が形成されている。図８（ａ）は、ハートカム溝２０における各地点ａ〜ｉを示している。図８（ｂ）は、ハートカム溝２０内をクランク１５のカム係合軸１５３が移動した場合のカム係合軸１５３の軌跡を示すとともに、ハートカム溝２０内の高低差を表す。図８（ｃ）は、溝内の傾斜面及び段差２６を視覚的に表しており、溝内の高さ方向に陰影を付している。   The heart cam groove 20 has an inclined surface and a step 26 formed in the groove. FIG. 8A shows the points a to i in the heart cam groove 20. FIG. 8B shows the locus of the cam engagement shaft 153 when the cam engagement shaft 153 of the crank 15 moves in the heart cam groove 20 and also shows the height difference in the heart cam groove 20. FIG. 8C visually shows the inclined surface and the step 26 in the groove, and is shaded in the height direction in the groove.

図８（ｂ）に示すように、ハートカム溝２０はケース本体１１の側面における外面側と内面側との間で凹凸が形成され、カム係合軸１５３は溝内の凹凸に沿って撓みながらスライド移動する。   As shown in FIG. 8B, the heart cam groove 20 has irregularities formed between the outer surface side and the inner surface side of the side surface of the case body 11, and the cam engagement shaft 153 slides while being bent along the irregularities in the groove. Moving.

図８（ａ）〜図８（ｃ）に示すように、ハートカム溝２０の第１往路２４１におけるａ地点からｂ地点までは、平坦な面である。ｂ地点からｃ地点までは、ａ地点からｂ地点までよりも高くなるように上り傾斜する（すなわち、ケース本体１１の外面側から内面側へ向かって傾斜する）。ｃ地点とｄ地点の間では、ａ地点からｂ地点までの面の深さまで戻るような段差２６が形成される（すなわち、ケース本体１１の外面側へ向かって低くなる）。ｄ地点は、第１の凸部２１に対応し、ａ地点からｄ地点までが第１往路２４１を構成する。
第２往路２４２におけるｄ地点からｅ地点までは、ｄ地点よりも高くなるように上り傾斜する。ｅ地点とｆ地点の間では、ｄ地点の深さまで戻るような段差２６が形成される。ｆ地点は、中間部２３を構成する。
第１復路２５１におけるｆ地点からｇ地点までは、ｆ地点よりも高くなるように上り傾斜する。ｇ地点とｈ地点の間では、ｆ地点の深さまで戻るような段差２６が形成される。ｈ地点は、第２の凸部２２を構成する。
第２復路２５２におけるｈ地点からｉ地点までは、ｈ地点よりも高くなるように傾斜する。ｉ地点とｂ地点の間では、ｂ地点の深さまで戻るような段差２６が形成される。
第２復路２５２は、その終端側で第１往路２４１に接続され、二つの経路が合流してｂ地点からａ地点に向かう。 As shown in FIG. 8A to FIG. 8C, the point a to the point b in the first forward path 241 of the heart cam groove 20 is a flat surface. From the point b to the point c, the vehicle is inclined to be higher than that from the point a to the point b (that is, inclined from the outer surface side to the inner surface side of the case body 11). A step 26 is formed between the point c and the point d so as to return to the depth of the surface from the point a to the point b (that is, lower toward the outer surface side of the case body 11). The point d corresponds to the first convex portion 21, and the first forward path 241 is configured from the point a to the point d.
From the point d to the point e on the second forward path 242, the vehicle inclines so as to be higher than the point d. A step 26 is formed between the point e and the point f so as to return to the depth of the point d. The point f constitutes the intermediate part 23.
From the point f to the point g on the first return path 251, the vehicle inclines so as to be higher than the point f. A step 26 is formed between the point g and the point h so as to return to the depth of the point f. The point h constitutes the second convex portion 22.
From the point h to the point i on the second return path 252, the vehicle inclines so as to be higher than the point h. A step 26 is formed between point i and point b so as to return to the depth of point b.
The second return path 252 is connected to the first forward path 241 on the terminal side, and the two paths merge to go from the point b to the point a.

以上の受け金具３１及び係合部３２により構成される一対の係合部材３０と、ハートカム溝２０と、クランク１５及びばね１４により、キャッチ機構及びポップアップ機構が構成される。
次に、開閉装置１の使用状態について説明する。 A catch mechanism and a pop-up mechanism are constituted by the pair of engaging members 30 constituted by the receiving metal fitting 31 and the engaging portion 32, the heart cam groove 20, the crank 15 and the spring 14.
Next, the use state of the switchgear 1 will be described.

図４及び図６は、引込戸１００が戸袋２００に収納されて開閉装置が待機位置に位置するまでを示す。図４及び図６では、各図がそれぞれ対応しており、図４（ａ）及び図６（ａ）は、受け金具３１と係合部３２とが接触した状態を示し、図４（ｂ）及び図６（ｂ）は、クランク１５が待機位置に至る寸前の状態を示し、図４（ｃ）及び図６（ｃ）は、クランク１５の待機位置を示す。   4 and 6 show the state in which the retractable door 100 is accommodated in the door pocket 200 and the opening / closing device is positioned at the standby position. 4 and 6 correspond to each other, and FIGS. 4 (a) and 6 (a) show a state in which the metal fitting 31 and the engaging portion 32 are in contact with each other, and FIG. 4 (b). 6B shows a state immediately before the crank 15 reaches the standby position, and FIGS. 4C and 6C show the standby position of the crank 15. FIG.

まず、図１（ａ）に示すように、引込戸１００は、戸袋２００から完全に外部に出た閉状態にある。閉状態では、部屋と部屋の間が仕切られている。この仕切りを開放するため、引込戸１００を図４（ａ）、（ｂ）の矢印で示す開方向にスライド移動させ、戸袋２００の中に収納することで、引込戸１００を閉状態から開状態に向けて移動させる。このとき、引込戸１００に設けられている本体部１０は、スライドレール１０１内をスライド移動する。
図１（ｂ）に示すように、引込戸１００は、戸袋２００の戸先側でストッパー２０２により受け止められ、衝撃が低減される。 First, as shown to Fig.1 (a), the retractable door 100 exists in the closed state which came out from the door pocket 200 completely outside. In the closed state, the rooms are separated from each other. To open the partition, the sliding door 100 is slid in the opening direction indicated by the arrows in FIGS. 4A and 4B and stored in the door pocket 200, so that the sliding door 100 is opened from the closed state. Move towards. At this time, the main body 10 provided in the pull-in door 100 slides within the slide rail 101.
As shown in FIG.1 (b), the retractable door 100 is received by the stopper 202 in the door end side of the door pocket 200, and an impact is reduced.

図４（ａ）及び図６（ａ）に示すように、引込戸１００を開方向にスライドさせて戸袋２００の中へ収納していくと、引込戸１００の上部に設けられた開閉装置１におけるケース本体１１の上部で、係合部３２が受け金具３１に接触する。このとき、第１係合部３２１が、受け金具３１の被係合突出部３１２に引っ掛かる。ばね１４は、係合部３２が受け金具３１に近付いて接触するまでは、付勢力を発生させない非伸長状態にある。   As shown in FIGS. 4A and 6A, when the retracting door 100 is slid in the opening direction and stored in the door pocket 200, the opening / closing device 1 provided on the upper portion of the retracting door 100 is used. At the upper part of the case body 11, the engaging part 32 contacts the receiving metal 31. At this time, the first engaging portion 321 is caught by the engaged protruding portion 312 of the metal fitting 31. The spring 14 is in a non-extended state in which no urging force is generated until the engaging portion 32 approaches and contacts the receiving metal fitting 31.

係合部３２が受け金具３１に接触した後、引込戸１００をさらに開方向へ移動させると、第１係合部３２１が、受け金具３１の被係合突出部３１２に引っ掛かった状態で、ケース本体１１が戸先側へ進み、係合部案内溝１３の内部に第２係合軸３２４を挿通させた状態で進行する。このとき、第２係合軸３２４は上方に上がり、第２係合部３２２も上方に揺動して被係合突出部３１２に係合する。第２係合軸３２４が係合部案内溝１３の戸尻側端部１３ｂに当接した後、さらに引込戸１００を開方向への荷重が加えられた場合、第１係合部３２１には戸尻側に反り返るように回転する荷重が加わる。しかし、スライダー１６の突出部１６１に、係合部３２の戸尻側の端部が当接することより、係合部３２が過回転しないように受け止められる。   When the retracting door 100 is further moved in the opening direction after the engaging portion 32 comes into contact with the receiving metal fitting 31, the first engaging portion 321 is caught by the engaged protruding portion 312 of the receiving metal fitting 31. The main body 11 advances to the door end side, and proceeds with the second engagement shaft 324 inserted through the engagement portion guide groove 13. At this time, the second engagement shaft 324 rises upward, and the second engagement portion 322 also swings upward and engages with the engaged protrusion 312. After the second engagement shaft 324 comes into contact with the door butt side end portion 13b of the engagement portion guide groove 13, a load in the opening direction of the retracting door 100 is further applied to the first engagement portion 321. A rotating load is applied so as to warp the side of the door. However, the end of the engaging portion 32 on the door bottom side comes into contact with the protruding portion 161 of the slider 16 so that the engaging portion 32 is received so as not to over-rotate.

なお、このとき、ケース本体１１もケース本体１１内部の係合部３２の移動にしたがって移動する。上部規制突起１１３の三角形状の角度は、係合部３２とスライダー１６の突出部１６１が当接して並んだ状態で形成される三角形の大きさと揃っている（図６（ｂ）参照）。第２係合軸３２４が係合部案内溝１３の戸尻側端部１３ｂに当接後、係合部３２の戸尻側端部がスライダー１６の突出部１６１に当接すると同時に、係合部３２の戸尻側端部が上部規制突起１１３に当接することで、係合部３２が過回転しないように受け止められる。   At this time, the case main body 11 also moves according to the movement of the engaging portion 32 inside the case main body 11. The triangular angle of the upper restricting protrusion 113 is aligned with the size of the triangle formed in a state where the engaging portion 32 and the protruding portion 161 of the slider 16 are in contact with each other (see FIG. 6B). After the second engagement shaft 324 is in contact with the door butt side end 13b of the engagement portion guide groove 13, the door butt side end of the engagement portion 32 is in contact with the protrusion 161 of the slider 16 and is engaged at the same time. Since the door butt side end portion of the portion 32 abuts on the upper regulating protrusion 113, the engaging portion 32 is received so as not to over-rotate.

また、引込戸１００の移動に伴ってケース本体１１が戸先側へ移動することで、ばね１４が戸先側へ引っ張られて伸ばされ、引込戸１００を開方向に付勢させる第１伸長状態になる。このとき、使用者が引込戸１００を押すことで、引込戸１００に戸先側へ進行する慣性が働くが、引込戸１００の慣性は、ばね１４を引っ張ることで相殺される。すなわち、ばね１４が引っ張られることで、付勢力が発生し、引込戸１００の戸先側へ進む速度が減衰する。引込戸１００の移動速度が適切であれば、引込戸１００のスライド移動に伴って、クランク１５はハートカム溝２０内の第１往路２４１（ａ地点からｄ地点）を移動して第１の凸部２１へ進み、第１往路２４１の戸尻側の端部で第１の凸部２１の頂点に達する。このとき、ｄ地点には、ｃ地点よりもｄ地点の方が深く（ケース本体１１の外面側に）下がるような段差２６が形成されているので、ｄ地点からｃ地点の方向、すなわち第１往路２４１を逆流するような方向へクランク１５のカム係合軸１５３が戻ることはできない（図８（ａ）〜（ｃ）参照）。   Moreover, the case main body 11 moves to the door-end side with the movement of the retractable door 100, so that the spring 14 is pulled and extended toward the door-end side, and the first extended state that biases the retractable door 100 in the opening direction. become. At this time, when the user pushes the retracting door 100, the inertia of the retracting door 100 proceeds toward the door tip side, but the inertia of the retracting door 100 is offset by pulling the spring 14. That is, when the spring 14 is pulled, a biasing force is generated, and the speed of the retracting door 100 toward the door end is attenuated. If the moving speed of the retracting door 100 is appropriate, the crank 15 moves along the first forward path 241 (from the point a to the point d) in the heart cam groove 20 as the sliding door 100 moves, so that the first convex portion 21, and reaches the apex of the first convex portion 21 at the end of the first forward path 241 on the door bottom side. At this time, since a step 26 is formed at the point d so that the point d is deeper than the point c (to the outer surface side of the case body 11), the direction from the point d to the point c, i.e., the first point. The cam engagement shaft 153 of the crank 15 cannot return in a direction that causes the reverse flow in the forward path 241 (see FIGS. 8A to 8C).

図４（ｂ）及び図６（ｂ）に示すように、クランク１５は、第１の凸部２１へ到達すると、ばね１４に引っ張られて第２往路２４２を移動する。また、クランク１５に対して重力も働くので、第１の凸部２１よりも下方の中間部２３へ移動して、中間部２３内に係止される。このとき、クランク１５のカム係合軸１５３は、ｄ地点からｅ地点まで上り斜面（ケース本体１１の内面側へ向かう斜面）を移動して、ｆ地点に形成された段差２６で落ちる（ケース本体１１の外面側に嵌まる）。カム係合軸１５３は、ｆ地点の方がｅ地点よりも低くなっているので、第１の凸部２１から中間部２３へ至る第２往路２４２を戻ることはできない（図８（ａ）〜（ｃ）参照）。   As shown in FIGS. 4B and 6B, when the crank 15 reaches the first convex portion 21, the crank 15 is pulled by the spring 14 and moves along the second forward path 242. Further, since gravity also acts on the crank 15, it moves to the intermediate portion 23 below the first convex portion 21 and is locked in the intermediate portion 23. At this time, the cam engagement shaft 153 of the crank 15 moves on the rising slope (slope toward the inner surface side of the case main body 11) from the point d to the point e and falls at the step 26 formed at the point f (the case main body). 11 fits on the outer surface side). Since the cam engagement shaft 153 is lower at the point f than the point e, the cam engagement shaft 153 cannot return the second forward path 242 from the first convex portion 21 to the intermediate portion 23 (FIG. 8A to FIG. 8). (See (c)).

図４（ｃ）及び図６（ｃ）に示すように、ばね１４の付勢力を維持した状態で、クランク１５のカム係合軸１５３が、ハートカム溝２０の中間部２３に至ることで、引込戸１００は戸尻側へ跳ね返ることなく不可逆的にキャッチされる。引込戸１００は、クランク１５が中間部２３に位置している間、戸袋２００内に収容された位置で、ばね１４により開方向に付勢された状態で保持される。こうして、引込戸１００の開状態が保持されるキャッチ機構が構成される。   As shown in FIGS. 4C and 6C, the cam engagement shaft 153 of the crank 15 reaches the intermediate portion 23 of the heart cam groove 20 while the biasing force of the spring 14 is maintained. The door 100 is irreversibly caught without bouncing back to the door bottom. The retractable door 100 is held in a state of being biased in the opening direction by the spring 14 at a position accommodated in the door pocket 200 while the crank 15 is positioned in the intermediate portion 23. Thus, a catch mechanism that holds the retracted door 100 in the open state is configured.

図５及び図７は、開閉装置１が待機位置から移動して引込戸１００が戸袋２００から開方向と反対の閉方向へ飛び出すようにポップアップする状態を示す。図５及び図７は、各図がそれぞれ対応しており、図５（ａ）及び図７（ａ）は、引込戸１００を戸袋２００に押し込まれた状態を示し、図５（ｂ）及び図７（ｂ）は、引込戸１００が戸袋２００から飛び出した状態を示す。   5 and 7 show a state in which the opening / closing device 1 moves from the standby position and pops up so that the retractable door 100 jumps out from the door pocket 200 in the closing direction opposite to the opening direction. 5 and FIG. 7 correspond to each figure, and FIG. 5A and FIG. 7A show a state in which the retractable door 100 is pushed into the door pocket 200, and FIG. 5B and FIG. 7 (b) shows a state in which the retractable door 100 jumps out of the door pocket 200.

図５（ａ）及び図７（ａ）に示すように、使用者は、引込戸１００を引き出したいと望んだ時に、引込戸１００の戸尻側の端面を、戸先側へ押圧する。すると、引込戸１００が開方向にさらに移動することで、引込戸１００の保持が解除され、クランク１５のカム係合軸１５３は、ハートカム溝２０内の中間部２３から、第１復路２５１を通り、第２の凸部２２へ変位する。このとき、クランク１５のカム係合軸１５３は、ｆ地点からｇ地点まで上り斜面（ケース本体１１の内面側へ向かう斜面）を移動して、ｈ地点に形成された段差２６で落ちる（ケース本体１１の外面側に嵌まる）。カム係合軸１５３は、ｈ地点の方がｇ地点よりも低くなっているので、第２の凸部２２から中間部２３へ至る第１復路２５１を戻ることはできない。   As shown in FIGS. 5A and 7A, when the user desires to pull out the retractable door 100, the user presses the end surface on the door bottom side of the retractable door 100 toward the door tip side. Then, when the retracting door 100 further moves in the opening direction, the retention of the retracting door 100 is released, and the cam engagement shaft 153 of the crank 15 passes through the first return path 251 from the intermediate portion 23 in the heart cam groove 20. Displacement to the second convex portion 22. At this time, the cam engaging shaft 153 of the crank 15 moves from the point f to the point g on the rising slope (the slope facing the inner surface of the case body 11) and falls at the step 26 formed at the point h (case body). 11 fits on the outer surface side). Since the cam engaging shaft 153 is lower at the h point than at the g point, the cam engaging shaft 153 cannot return the first return path 251 from the second convex portion 22 to the intermediate portion 23.

このように、中間部２３を挟んで往路２４側及び復路２５側の両側に、クランク１５の逆戻りを妨げる段差２６が形成されている。   In this manner, steps 26 that prevent the crank 15 from returning backward are formed on both sides of the forward path 24 and the return path 25 with the intermediate portion 23 interposed therebetween.

図５（ｂ）及び図７（ｂ）に示すように、クランク１５が第２の凸部２２へ移動すると、第２の凸部２２から復路２５の間にはクランク１５の移動を妨げるものがないので、第２復路２５２内の移動が自由になる。同時に、引込戸１００が戸先側へ押しこまれてクランク１５の中間部２３に対する係止が解かれると、戸先側へ引っ張られていたばね１４は、引込戸１００が閉方向へ移動する際に付勢力を解除する第２伸長状態となり、引込戸１００を押し戻す方向に復元する。引込戸１００は、ばね１４の復元力を受けながら、クランク１５がケース本体１１の第２復路２５２を通過し、戸先側へ移動することで、引込戸１００は戸袋２００の外側へポップアップする。戸袋２００から引込戸１００が飛び出した後は、使用者が引込戸１００の戸尻側端部を把持して、引き出す。こうして引込戸１００の開状態が閉状態に変化するポップアップ機構が構成される。   As shown in FIGS. 5B and 7B, when the crank 15 moves to the second convex portion 22, there is a thing that prevents the movement of the crank 15 between the second convex portion 22 and the return path 25. Therefore, the movement in the second return path 252 is free. At the same time, when the retracting door 100 is pushed toward the door end and the locking of the intermediate portion 23 of the crank 15 is released, the spring 14 that has been pulled toward the door end is moved when the retracting door 100 moves in the closing direction. It will be in the 2nd extension state which cancels energizing force, and it restores in the direction which pushes back retracting door 100. The retracting door 100 pops up to the outside of the door pocket 200 by the crank 15 passing through the second return path 252 of the case body 11 and moving toward the door tip side while receiving the restoring force of the spring 14. After the retractable door 100 pops out from the door pocket 200, the user grips and pulls out the door butt side end of the retractable door 100. Thus, a pop-up mechanism that changes the open state of the retractable door 100 to the closed state is configured.

図９は、使用者が引込戸１００を無理に引っ張り出そうとした状態を示す。図９（ａ）は、引込戸１００を無理に引き出そうとした状態、図９（ｂ）は、引き出した後、引込戸１００を戸袋２００内に戻そうとする状態、図９（ｃ）図は、引込戸１００が正常状態に復帰する状態を示す。   FIG. 9 shows a state where the user has forcibly pulled out the retractable door 100. FIG. 9A shows a state in which the pull-in door 100 is forcibly pulled out, FIG. 9B shows a state in which the pull-in door 100 is to be returned into the door pocket 200 after being pulled out, and FIG. The state which the retractable door 100 returns to a normal state is shown.

図９（ａ）に示すように、使用者が、引込戸１００を戸先側へ押し込むとポップアップするということを知らない場合、クランク１５が待機位置にある状態で、戸袋２００に指を入れて引込戸１００を掴み、開状態の引込戸１００を戸尻方向へ引っ張って移動させ、引き抜こうとすることが考えられる。この場合、クランク１５を待機状態に残したまま引込戸１００が戸尻側に引っ張られる。すると、本体部１０のケース本体１１と、ケース本体１１に連結されるダンパ９との連結部分が下方に撓んで沈み、係合部３２の第２係合部３２２が受け金具３１の被係合突出部３１２を超え、係合部３２と受け金具３１との互いの係合が解除される。この状態は、誤作動状態である。誤作動させた状態でさらに引込戸１００を引いて、戸袋２００から完全に取り出すと、そのまま閉状態へ引込戸１００を引くことができる。   As shown in FIG. 9 (a), when the user does not know that the pop-up will occur when the retracting door 100 is pushed into the door end side, the finger is put into the door pocket 200 with the crank 15 in the standby position. It is conceivable that the user pulls the pulling door 100 and pulls and moves the pulling door 100 in the open state toward the door butt. In this case, the retractable door 100 is pulled toward the door butt side while the crank 15 remains in the standby state. Then, the connecting portion between the case main body 11 of the main body 10 and the damper 9 connected to the case main body 11 is bent downward and sinks, and the second engaging portion 322 of the engaging portion 32 is engaged with the receiving metal 31. Beyond the protruding portion 312, the engagement between the engagement portion 32 and the receiving metal 31 is released. This state is a malfunctioning state. When the retracting door 100 is further pulled in a state where it is erroneously operated and completely taken out from the door pocket 200, the retracting door 100 can be pulled into the closed state as it is.

図９（ｂ）に示すように、閉状態の後、再び開状態にするため引込戸１００を戸袋２００に収納しようとするときは、クランク１５を待機位置に位置させたまま、引込戸１００を戸先方向へ移動させる。すると、図９（ｃ）に示すように、第２係合部３２２が受け金具３１に当たって揺動し、下方へ押される。すると、クランク１５は第２の凸部２２位置へ変位する。クランク１５が第２の凸部２２に移動した後は、第２復路２５２を移動し、正常状態に復帰して引込戸１００が戸袋２００に収納される。   As shown in FIG. 9 (b), when the retractable door 100 is to be stored in the door pocket 200 to be opened again after the closed state, the retractable door 100 is moved with the crank 15 positioned at the standby position. Move toward the door. Then, as shown in FIG. 9C, the second engaging portion 322 hits the receiving metal 31 and swings and is pushed downward. Then, the crank 15 is displaced to the second convex portion 22 position. After the crank 15 moves to the second convex portion 22, it moves on the second return path 252, returns to a normal state, and the retractable door 100 is stored in the door pocket 200.

図１０は、使用者が引込戸１００を無理に押し込んだ状態を示す。強い力で押し込むと、第１係合部３２１が受け金具３１を乗り越えて戸先側へ進もうとする。この場合、クランク１５が第２の凸部２２に移動するので、正常状態に復帰して、図５（ｂ）及び、図７（ｂ）と同じ状態で引込戸１００が飛び出る。引込戸１００をあまりに強く押しすぎると、キャッチ機構は作動しないが、開閉装置１が設けられているために、何も設置しない引込戸等の戸体と比べると、緩衝材的な役割を果たし、戸体周辺の戸枠やその他の部材に、戸体の移動と衝突による影響が及びにくい。   FIG. 10 shows a state in which the user has forced the retractable door 100. When pushed in with a strong force, the first engaging portion 321 tries to move over the receiving bracket 31 and advance toward the door-end side. In this case, since the crank 15 moves to the second convex portion 22, it returns to the normal state, and the retracting door 100 pops out in the same state as in FIG. 5B and FIG. 7B. If the retracting door 100 is pushed too strongly, the catch mechanism does not operate, but since the opening and closing device 1 is provided, it plays a role as a cushioning material compared to doors such as retracting doors where nothing is installed, The door frame and other members around the door are hardly affected by the movement and collision of the door.

図１１は、引込戸１００を強すぎる力で閉めた場合を示し、図１１（ａ）は引込戸１００が戸袋２００の閉端に衝突した状態を示し、図１１（ｂ）は、引込戸１００が戸袋２００に閉端にあたって反発した状態を示す。なお、ストッパー２０２は説明の便宜のため省略している。
図１１（ａ）に示すように、引込戸１００が戸袋２００の閉端に衝突して反発するほど強い力で押した場合でも、本実施形態では、クランク１５のカム係合軸１５３は、ハートカム溝２０のループから逃げられるように構成されていない。しかし、図１１（ｂ）に示すように、引込戸１００の衝突による衝撃は、本体部１０のケース本体１１と、ケース本体１１に連結されるダンパ９が下方に撓むことで、吸収される。ケース本体１１及びダンパ９は、スライドレール１０１内に軽く支持された状態で、ケース本体１１の下部に設けられた連結用突起１１１（図２参照）で連結されている。このため、連結された部分が撓むことで、ケース本体１１側又はダンパ９側に無理に力がかかっても、連結された他方にその力が及びにくくなるように構成されている。 11 shows a case where the retractable door 100 is closed with a too strong force, FIG. 11A shows a state where the retractable door 100 collides with the closed end of the door pocket 200, and FIG. 11B shows the retractable door 100. Shows a state in which the door pocket 200 is repelled when closed. The stopper 202 is omitted for convenience of explanation.
As shown in FIG. 11A, even when the retracting door 100 is pushed with a force strong enough to collide with the closed end of the door pocket 200 and repel, the cam engaging shaft 153 of the crank 15 is a heart cam. It is not configured to escape from the loop of the groove 20. However, as shown in FIG. 11B, the impact caused by the collision of the retracting door 100 is absorbed by the case main body 11 of the main body 10 and the damper 9 connected to the case main body 11 being bent downward. . The case main body 11 and the damper 9 are connected by a connecting projection 111 (see FIG. 2) provided at the lower portion of the case main body 11 while being lightly supported in the slide rail 101. For this reason, even if a force is applied to the case main body 11 side or the damper 9 side by bending the connected portion, the force is not easily applied to the other connected portion.

本実施形態によれば、以下の効果が奏される。
本実施形態によれば、上枠４１の長手方向に沿って移動可能な引込戸１００に用いられる開閉装置１を、上枠４１に、引込戸１００の開方向への移動により引込戸１００をばね１４により付勢させるとともに、ばね１４が付勢された状態で引込戸１００を所定位置に保持するキャッチ機構を含んで構成し、キャッチ機構が、引込戸１００の所定位置から引込戸１００の開方向へのさらなる移動により引込戸１００の保持を解除するように構成した。
本実施形態によれば、開閉装置１が、引込戸１００を勢いよく開けたときに、戸袋２００内の戸先側端部に跳ね返って飛び出てしまわないように、引込戸１００を開方向に引っ張る一方で、引込戸１００が開方向へ移動する慣性を減衰させるばね１４を設けた。これにより、引込戸１００の移動を減速させるとともに保持するキャッチ機構と、戸袋２００内に完全に収納された引込戸１００を、戸袋２００に指を入れて取り出そうとしなくとも、引込戸１００の戸尻側の端面を押して開方向へさらに移動させるだけで自動的に開方向と逆の閉方向へ飛び出すように移動させるポップアップ機構と、の両方を兼ね添えることができる。ある程度の勢いをもって引込戸１００を戸袋２００に収容するように押した場合でも、引込戸１００をキャッチできる一方で、閉方向に飛び出させるポップアップ機構を有するので、引込戸１００の出し入れが容易になる。
また、引込戸１００にポップアップ用の機能部品を別途取り付ける必要がなくなり、引込戸１００を跳ね返すために強度の高い部材を取り付ける必要がなくなるので、製造コストが低減される。 According to this embodiment, the following effects are produced.
According to the present embodiment, the opening / closing device 1 used for the retractable door 100 movable along the longitudinal direction of the upper frame 41 is moved to the upper frame 41 by moving the retractable door 100 in the opening direction by the spring. 14, and includes a catch mechanism that holds the retractable door 100 in a predetermined position in a state where the spring 14 is biased, and the catch mechanism opens from the predetermined position of the retractable door 100 to the opening direction of the retractable door 100. It was comprised so that holding | maintenance of the retractable door 100 might be cancelled | released by the further movement to.
According to the present embodiment, when the opening / closing device 1 opens the retracting door 100 vigorously, the opening / closing device 1 pulls the retracting door 100 in the opening direction so that the opening / closing device 1 does not jump back and jump out to the door end side end in the door pocket 200. On the other hand, a spring 14 that damps the inertia of the retractable door 100 moving in the opening direction is provided. Thus, the catch mechanism that decelerates and holds the movement of the pull-in door 100 and the pull-in door 100 that is completely stored in the door pocket 200 can be removed without putting the finger into the door pocket 200 and taking out the door. A pop-up mechanism that automatically moves in a closing direction opposite to the opening direction by simply pushing the end face on the side and moving it further in the opening direction can be used. Even when the retractable door 100 is pushed so as to be accommodated in the door pocket 200 with a certain amount of momentum, the retractable door 100 can be caught, but since the pop-up mechanism that pops out in the closing direction is provided, the retractable door 100 can be easily put in and out.
In addition, it is not necessary to separately attach a functional component for pop-up to the pull-in door 100, and it is not necessary to attach a high-strength member to rebound the pull-in door 100, so that the manufacturing cost is reduced.

本実施形態によれば、開閉装置１を、引込戸１００とともにスライド移動可能な本体部１０をさらに含んで構成した。また、本体部１０を、その内部に設けられるハートカム溝２０及び該ハートカム溝２０に係合することでハートカム溝２０に沿って移動可能なクランク１５を含んで構成し、ハートカム溝２０を、引込戸１００が開方向に移動する際に内部をクランク１５が移動する往路２４と、往路２４の終端から、往路２４と異なる経路に延びる復路２５と、往路２４及び復路２５の間に配置され、引込戸１００がキャッチ機構に保持されるときにクランク１５が位置する中間部２３と、を含んで構成し、中間部２３を挟んで往路２４側及び復路２５側の両側に、クランク１５の逆戻りを妨げる段差２６を形成した。
本実施形態によれば、引込戸１００とともにスライド移動する本体部１０の内部に、本体部の移動する軌道を規定するハートカム溝２０と、ハートカム溝２０内を移動するクランク１５とを設けた。そして、引込戸１００がキャッチ機構に保持された位置のときにクランク１５が位置する中間部を挟んだ往路２４側と復路２５側に段差２６を設け、クランク１５が進行方向と逆の方向に逆戻りしないように構成した。これにより、クランク１５の逆戻りや誤作動が防止できるので、本体部１０とともにスライド移動する引込戸１００の移動を正確にすることができ、キャッチ機構及びポップアップ機構を有効に働かせることができる。 According to the present embodiment, the opening / closing device 1 is configured to further include the main body 10 that can slide along with the retractable door 100. The main body 10 includes a heart cam groove 20 provided therein and a crank 15 that can move along the heart cam groove 20 by engaging with the heart cam groove 20. The forward path 24 in which the crank 15 moves when the 100 moves in the opening direction, the return path 25 extending from the end of the forward path 24 to a path different from the forward path 24, and between the forward path 24 and the return path 25, and the retractable door And an intermediate portion 23 in which the crank 15 is positioned when the 100 is held by the catch mechanism, and a step that prevents the crank 15 from reversing on both sides of the forward path 24 side and the return path 25 side across the intermediate portion 23. 26 was formed.
According to the present embodiment, the heart cam groove 20 that defines the trajectory in which the main body portion moves and the crank 15 that moves in the heart cam groove 20 are provided in the main body portion 10 that slides together with the retracting door 100. Then, when the retracting door 100 is held by the catch mechanism, a step 26 is provided on the forward path 24 side and the return path 25 side across the intermediate portion where the crank 15 is located, so that the crank 15 returns in the direction opposite to the traveling direction. Configured not to. Thereby, since the reverse rotation and malfunction of the crank 15 can be prevented, the movement of the retractable door 100 that slides together with the main body 10 can be made accurate, and the catch mechanism and the pop-up mechanism can be effectively operated.

本実施形態によれば、往路２４を、引込戸１００の開方向への移動を可能にする第１往路２４１と、第１往路２４１の終端から折り返すように延びる第２往路２４２と、を含んで構成し、復路２５を、第２往路２４２の終端側から、第１往路２４１の進行方向に沿って延びる第１復路２５１と、第１復路２５１の終端から第１往路２４１の進行方向と逆方向へ向かって延びる第２復路２５２を、を含んで構成した。また、中間部２３を、第２往路２４２の終端及び第１復路２５１の始端を結ぶ位置に配置し、第２往路２４２の長さと、第１復路２５１の長さとを、実質的に等しく構成した。
中間部２３が、引込戸１００がキャッチ機構に保持された位置のときにクランク１５が位置する地点であることから、第２往路２４２は、クランク１５が中間部２３に保持されて待機位置へ移動し、引込戸１００がキャッチされるまでの経路である。また、第１復路は、引込戸１００をさらに開方向へ押したときに、キャッチ機構が解除されるまでの経路である。したがって、第２往路２４２の長さと、第１復路２５１の長さとを、実質的に等しくすることで、引込戸１００を開閉装置１にキャッチさせるために必要な力と、キャッチ機構を解除する力とを、ほぼ同程度の力に揃えることが可能となる。これにより、引込戸１００を取り扱う力の強さが平均的になるので、引込戸１００を押し込む際の操作感と、戸体１００を一端押して飛び出すようにポップアップさせる操作感が同等となり、利便性が高まる。 According to the present embodiment, the forward path 24 includes the first forward path 241 that enables the retractable door 100 to move in the opening direction, and the second forward path 242 that extends so as to be folded back from the end of the first forward path 241. The return path 25 is configured to have a first return path 251 extending from the terminal end side of the second forward path 242 along the traveling direction of the first forward path 241, and a direction opposite to the travel direction of the first forward path 241 from the terminal end of the first return path 251. A second return path 252 extending toward the front is configured to include. Further, the intermediate portion 23 is arranged at a position connecting the end of the second forward path 242 and the start end of the first return path 251 so that the length of the second forward path 242 and the length of the first return path 251 are substantially equal. .
Since the intermediate portion 23 is a point where the crank 15 is located when the retracting door 100 is held by the catch mechanism, the second forward path 242 moves to the standby position with the crank 15 held by the intermediate portion 23. And it is a path | route until the retractable door 100 is caught. The first return path is a path until the catch mechanism is released when the retracting door 100 is further pushed in the opening direction. Accordingly, by making the length of the second forward path 242 and the length of the first return path 251 substantially the same, a force necessary for causing the opening / closing device 1 to catch the opening / closing device 1 and a force for releasing the catch mechanism. Can be made to have almost the same level of force. Thereby, since the strength of the force to handle the retractable door 100 becomes average, the operational feeling when pushing in the retractable door 100 is equivalent to the operational feeling of popping up the door body 100 by pushing it once. Rise.

本実施形態によれば、本体部１０を、上枠４１に固定されるスライドレール１０１内をスライド移動するように構成した。これにより、引込戸１００がスムーズに移動する。   According to this embodiment, the main body 10 is configured to slide in the slide rail 101 fixed to the upper frame 41. Thereby, the retractable door 100 moves smoothly.

本実施形態によれば、スライドレール１０１に固定される受け金具３１及び本体部１０に設けられる係合部３２により構成される一対の係合部材３０をさらに含んで構成し、一対の係合部材３０を、開状態の引込戸１００閉方向に引張り移動させたときに互いの係合が解除されるように構成した。これにより、引込戸１００が閉状態へ移動できるように開閉装置１内の機構が配置されていないときに、無理やり引込戸１００を引張り移動させても、開閉装置１は故障することなく正常状態に復帰し、安全に引込戸１００の開閉を行うことができる。   According to the present embodiment, it further includes a pair of engaging members 30 constituted by a receiving metal fitting 31 fixed to the slide rail 101 and an engaging portion 32 provided in the main body 10, and a pair of engaging members When the sliding doors 30 are pulled and moved in the closing direction of the retracting door 100 in the open state, the mutual engagement is released. Thereby, when the mechanism in the opening / closing device 1 is not arranged so that the retracting door 100 can be moved to the closed state, even if the retracting door 100 is forcibly pulled and moved, the opening / closing device 1 is in a normal state without failure. It returns and can open and close the retractable door 100 safely.

本実施形態によれば、戸体を戸袋２００に収容される引込戸１００により構成し、戸袋２００内の上端側における戸先側に、ストッパー２０２を設けた。これにより、引込戸１００が高速で戸袋２００内に入ったときに引込戸１００はストッパー２０２に接触するので、引込戸１００が戸袋２００内に進入する際に衝撃を和らげ、引込戸１００及び開閉装置１の破損が防止される。また、ストッパー２０２が、引込戸１００が戸袋２００の戸先側端面に当たる衝撃を弱められるので、引込戸１００が戸尻側へ戻る勢いが弱まり、開閉装置１が引込戸１００をキャッチすることの可能な引込戸１００の慣性速度の範囲を広げることができる。   According to the present embodiment, the door body is configured by the retractable door 100 accommodated in the door pocket 200, and the stopper 202 is provided on the door end side at the upper end side in the door pocket 200. Accordingly, when the retractable door 100 enters the door pocket 200 at a high speed, the retractable door 100 contacts the stopper 202, so that the impact is reduced when the retractable door 100 enters the door pocket 200, and the retractable door 100 and the opening and closing device 1 is prevented from being damaged. Moreover, since the stopper 202 can weaken the impact which the retracting door 100 hits the door end side end surface of the door pocket 200, the force which the retracting door 100 returns to the door bottom side becomes weak, and the opening / closing apparatus 1 can catch the retracting door 100. The range of inertia speed of the retractable door 100 can be expanded.
