Description

本発明は、引戸の自動閉止装置に関し、特に、引戸を最初に開けるときに要する力を軽減し、この開き始めに要する力と、所定の開放位置でキャッチ部材がトリガーから離脱した後に要する力との差を小さくするようにした引戸の自動閉止装置に関するものである。   The present invention relates to an automatic closing device for a sliding door, and in particular, reduces the force required to open the sliding door for the first time, the force required to start the opening, and the force required after the catch member is detached from the trigger at a predetermined opening position. The present invention relates to an automatic closing device for a sliding door in which the difference is reduced.

従来から引戸を閉止する際に、引戸に加えた力が大きすぎた場合、戸枠に引戸が衝突して衝撃音が発生したり、跳ね返って完全に閉止できないことがあった。
逆に引戸に加える力が小さすぎた場合、完全に引戸が閉まらずに途中で止まってしまうことがあった。 Conventionally, when the sliding door is closed, if the force applied to the sliding door is too large, the sliding door may collide with the door frame to generate an impact sound or bounce back and cannot be completely closed.
On the other hand, if the force applied to the sliding door is too small, the sliding door may not be completely closed and may stop halfway.

このような問題に対処すべく、引戸を所定の開放位置から閉止位置まで自動的に閉じるようにした引戸の自動閉止装置がある。
この引戸の自動閉止装置は、引戸上部に配設され引戸を閉止方向に付勢するダンパーと、該ダンパーのロッドに固定されたスライダと、該スライダと対向するように戸枠側に設けられたトリガーと、スライダに設けられ、所定の開放位置でトリガーと係脱するキャッチ部材とを備えている。
そして、引戸をダンパーで閉止方向に一定速度で押圧することにより、引戸の急激な閉じ動作を防止するとともに、引戸を閉止位置まで自動的に閉じるようにしている。 In order to deal with such a problem, there is an automatic closing device for a sliding door that automatically closes the sliding door from a predetermined opening position to a closing position.
This automatic closing device for a sliding door is provided on the door frame side so as to face the slider, a damper disposed on the upper part of the sliding door and biasing the sliding door in the closing direction, a slider fixed to the rod of the damper. A trigger and a catch member provided on the slider and engaged with and disengaged from the trigger at a predetermined opening position are provided.
Then, the sliding door is pressed at a constant speed in the closing direction by a damper to prevent a sudden closing operation of the sliding door and to automatically close the sliding door to the closing position.

ところで、この従来の引戸の自動閉止装置ではダンパーの力が大きくなるため、引戸を最初に開けるときに大きな力が必要となり、この開き始めに要する力と、所定の開放位置でキャッチ部材がトリガーから離脱した後に要する力との差が大きくなりすぎるという問題があった。   By the way, in this conventional automatic door closing device, the force of the damper becomes large, so a large force is required when opening the sliding door for the first time, and the force required to start the opening and the catch member at the predetermined opening position from the trigger. There was a problem that the difference from the force required after separation was too large.

本発明は、上記従来の引戸の自動閉止装置が有する問題点に鑑み、引戸を最初に開けるときに要する力を軽減し、この開き始めに要する力と、所定の開放位置でキャッチ部材がトリガーから離脱した後に要する力との差を小さくするようにした引戸の自動閉止装置を提供することを目的とする。   In view of the problems of the conventional automatic door closing device, the present invention reduces the force required to open the sliding door for the first time, and the force required to start opening the catch member from the trigger at a predetermined opening position. An object of the present invention is to provide an automatic closing device for a sliding door in which a difference from a force required after the separation is reduced.

上記目的を達成するため、本発明の引戸の自動閉止装置は、引戸上部に配設され引戸を閉止方向に付勢するダンパーと、該ダンパーのロッドに配設されたスライダと、該スライダと対峙するように戸枠側に設けられたトリガーと、スライダに設けられ、所定の開放位置でトリガーと係脱するキャッチ部材とを備え、引戸を所定の開放位置から閉止位置まで自動的に閉じるようにした引戸の自動閉止装置において、スライダを引戸の開き方向に付勢してダンパーの付勢力を減衰するばね部材をダンパーに対して並設したことを特徴とする。   In order to achieve the above object, an automatic closing device for a sliding door according to the present invention includes a damper disposed on an upper portion of the sliding door and biasing the sliding door in a closing direction, a slider disposed on a rod of the damper, and the slider. A trigger provided on the door frame side and a catch member provided on the slider for engaging with and disengaging from the trigger at a predetermined opening position so as to automatically close the sliding door from the predetermined opening position to the closing position. In the sliding door automatic closing device, a spring member that urges the slider in the sliding door opening direction to attenuate the urging force of the damper is provided in parallel with the damper.

この場合において、ばね部材の固定側端部に、ばね部材の張力を調整するばね調整ねじを設けることができる。   In this case, a spring adjusting screw for adjusting the tension of the spring member can be provided at the fixed side end of the spring member.

また、キャッチ部材がスライダに揺動可能に枢支され、トリガーと係合することによりガイドレール上を移動し、ガイドレールの終端で転倒することによりトリガーから離脱するとともに、転倒することにより上昇したキャッチ部材の尾部をトリガーの押片で掛止することによりキャッチ部材を起こすように構成し、前記トリガーの押片の掛止部を円弧状の凹部として形成することができる。   In addition, the catch member is pivotally supported by the slider, moves on the guide rail by engaging with the trigger, moves away from the trigger by falling at the end of the guide rail, and rises by falling. The catch member can be raised by hooking the tail portion of the catch member with the pressing piece of the trigger, and the hooking portion of the trigger pressing piece can be formed as an arcuate recess.

本発明の引戸の自動閉止装置によれば、引戸上部に配設され引戸を閉止方向に付勢するダンパーと、該ダンパーのロッドに配設されたスライダと、該スライダと対峙するように戸枠側に設けられたトリガーと、スライダに設けられ、所定の開放位置でトリガーと係脱するキャッチ部材とを備え、引戸を所定の開放位置から閉止位置まで自動的に閉じるようにした引戸の自動閉止装置において、スライダを引戸の開き方向に付勢してダンパーの付勢力を減衰するばね部材をダンパーに対して並設したことから、このばね部材によってダンパーの大きすぎる力を減衰して、引戸を最初に開けるときに要する力を軽減し、この開き始めに要する力と、所定の開放位置でキャッチ部材がトリガーから離脱した後に要する力との差を小さくすることができ、また、装置全体の大きさが長大になるのを防止することができる。   According to the automatic closing device for a sliding door of the present invention, a damper disposed on the sliding door and biasing the sliding door in a closing direction, a slider disposed on the rod of the damper, and a door frame so as to face the slider Automatic closing of the sliding door, which is provided with a trigger provided on the side and a catch member provided on the slider, which is engaged with and disengaged from the trigger at a predetermined opening position, and automatically closes the sliding door from the predetermined opening position to the closing position. In the device, since the spring member that urges the slider in the opening direction of the sliding door and attenuates the urging force of the damper is arranged in parallel with the damper, the spring member attenuates the excessive force of the damper and the sliding door is This reduces the force required to open the first time and reduces the difference between the force required to start opening and the force required after the catch member is released from the trigger at a predetermined opening position. In addition, it is possible to prevent the size of the entire apparatus becomes long.

また、ばね部材の固定側端部に、ばね部材の張力を調整するばね調整ねじを設けることにより、引戸の重量に合わせてダンパーの力を調節し、重い引戸でも閉じるようにしたり、軽い引戸でもゆっくりと閉じるようにすることができる。   In addition, by providing a spring adjustment screw that adjusts the tension of the spring member at the fixed end of the spring member, the force of the damper can be adjusted according to the weight of the sliding door so that it can be closed even with a heavy sliding door, It can be closed slowly.

また、キャッチ部材がスライダに揺動可能に枢支され、トリガーと係合することによりガイドレール上を移動し、ガイドレールの終端で転倒することによりトリガーから離脱するとともに、転倒することにより上昇したキャッチ部材の尾部をトリガーの押片で掛止することによりキャッチ部材を起こすように構成し、前記トリガーの押片の掛止部を円弧状の凹部として形成することにより、キャッチ部材が起きるときにその尾部を円弧状の凹部で案内することができ、これにより、キャッチ部材とトリガーとが係合する際の衝撃音をなくすことができる。   In addition, the catch member is pivotally supported by the slider, moves on the guide rail by engaging with the trigger, moves away from the trigger by falling at the end of the guide rail, and rises by falling. When the catch member is formed by hooking the tail portion of the catch member with the trigger pressing piece to raise the catch member, and forming the hook pressing portion of the trigger pressing piece as an arcuate recess The tail portion can be guided by the arc-shaped concave portion, thereby eliminating the impact sound when the catch member and the trigger are engaged.

以下、本発明の引戸の自動閉止装置の実施の形態を、図面に基づいて説明する。   Embodiments of the automatic closing device for sliding doors of the present invention will be described below with reference to the drawings.

図１〜図４に、本発明の引戸の自動閉止装置の一実施例を示す。
この引戸の自動閉止装置は、引戸（図示省略）の上部に配設され引戸を閉止方向に付勢するダンパー１と、該ダンパー１のロッド１ａに配設されたスライダ２と、該スライダ２と対峙するように戸枠（図示省略）側に設けられたトリガー３と、スライダ２に設けられ、所定の開放位置でトリガー３と係脱するキャッチ部材４とを備え、引戸を所定の開放位置から閉止位置まで自動的に閉じるようにしている。
そして、スライダ２を引戸の開き方向に付勢してダンパー１の付勢力を減衰するばね部材５をダンパー１に対して並設するようにしている。 1 to 4 show an embodiment of an automatic closing device for a sliding door according to the present invention.
This automatic closing device for a sliding door includes a damper 1 disposed on an upper portion of a sliding door (not shown) and biasing the sliding door in a closing direction, a slider 2 disposed on a rod 1a of the damper 1, and the slider 2 A trigger 3 provided on the door frame (not shown) side so as to face each other, and a catch member 4 provided on the slider 2 and engaged with and disengaged from the trigger 3 at a predetermined opening position are provided, and the sliding door is moved from the predetermined opening position. It automatically closes to the closing position.
A spring member 5 that urges the slider 2 in the opening direction of the sliding door to attenuate the urging force of the damper 1 is arranged in parallel with the damper 1.

ダンパー１は、本実施例においては、より耐久性を持たせるために、ガスダンパーを使用しているが、同じ機能を有する各種ダンパーを用いることができる。
ダンパー１をスライダ２に直結することによって、ダンパー１に直接かかる力を軽減するとともに、ダンパー１がよりスムーズに負担のない動きができるようにしている。
キャッチ部材４をダンパー１に直接取り付けてしまうと、ダンパー１に圧力がかかりすぎ、動きがスムーズにならなくなる。このため、スライダ２にキャッチ部材４を取り付け、スライダ２でダンパー１にかかる負荷を抑えるようにしている。 In the present embodiment, the damper 1 uses a gas damper in order to make it more durable, but various dampers having the same function can be used.
By directly connecting the damper 1 to the slider 2, the force applied directly to the damper 1 is reduced, and the damper 1 can move more smoothly and without a load.
If the catch member 4 is directly attached to the damper 1, too much pressure will be applied to the damper 1, and the movement will not be smooth. For this reason, the catch member 4 is attached to the slider 2, and the load applied to the damper 1 by the slider 2 is suppressed.

また、ダンパー１とスライダ２の動きをよりよくするために、ダンパー１のロッド１ａとスライダ２を直接取り付けるのではなく、緩衝材として軟質塩化ビニルの棒材２１を間に介在させることも可能である。
これにより、スライダ２に負荷がかかったとしても、ダンパー１とスライダ２の間にある程度の遊びの部分を作ることができ、これにより、ダンパー１に負荷をかけることなくスムーズな動きをさせることができる。
なお、軟質塩化ビニルの棒材２１は、パイプ２２を介してダンパー１のロッド１ａと接続されている。 Further, in order to improve the movement of the damper 1 and the slider 2, the rod 1a of the damper 1 and the slider 2 are not directly attached, but a soft vinyl chloride bar 21 can be interposed as a cushioning material. is there.
As a result, even if a load is applied to the slider 2, a certain amount of play can be created between the damper 1 and the slider 2, so that the damper 1 can move smoothly without applying a load. it can.
The soft vinyl chloride bar 21 is connected to the rod 1 a of the damper 1 through a pipe 22.

スライダ２は、図２に示すように、その基部側から上にばね掛け部２３を突設するとともに、該ばね掛け部２３とケーシング６の端部との間に、ばね部材５として引っ張りばねを介設している。
ばね部材５の固定側端部には、ばね部材５の張力を調整するばね調整ねじ７が設けられており、引戸の重量に合わせてダンパー１の力を調節することにより、重い引戸でも閉じられるようにしたり、軽い引戸でもゆっくりと閉じられるようにしている。
具体的には、ばね調整ねじ７を締めれば、ばね部材５が緩んでダンパー１にかかる力が少なくなり、重い引戸でも閉めることができ、反対にばね調整ねじ７を緩めれば、ばね部材５が伸ばされダンパー１にかかる力が大きくなり、軽い引戸もゆっくり閉めることができる。 As shown in FIG. 2, the slider 2 has a spring hook 23 protruding upward from its base side, and a tension spring as a spring member 5 between the spring hook 23 and the end of the casing 6. It is installed.
A spring adjustment screw 7 for adjusting the tension of the spring member 5 is provided at the fixed side end of the spring member 5, and even a heavy sliding door can be closed by adjusting the force of the damper 1 according to the weight of the sliding door. It can be closed slowly even with a light sliding door.
Specifically, if the spring adjusting screw 7 is tightened, the spring member 5 is loosened and the force applied to the damper 1 is reduced, so that even a heavy sliding door can be closed. Conversely, if the spring adjusting screw 7 is loosened, the spring member 5 Is extended, the force applied to the damper 1 is increased, and the light sliding door can be closed slowly.

一方、キャッチ部材４は、図４（ｂ）に示すように、スライダ２上のベース２４に揺動可能に枢支されており、戸枠側のトリガー３と係合することによりガイドレール８の上を移動し、ガイドレール８の終端８１で転倒することによりトリガー３から離脱する。
なお、転倒したキャッチ部材４は、ガイドレール８の終端８１に掛止することにより、転倒した姿勢を保ちながらダンパー１の付勢力に抗してその位置で停止する。
そして、図４（ａ）に示すように、転倒することにより上昇したキャッチ部材４の尾部４１を、トリガー３の押片３１が掛止することによりキャッチ部材４が起き、トリガー３と係合するようになっている。
この場合、本実施例では、前記トリガー３の押片３１の掛止部３２を円弧状（半円状）の凹部として形成している。
これにより、キャッチ部材４が起きるときに、キャッチ部材４の突出する尾部４１を円弧状の凹部で円滑に案内し、キャッチ部材４とトリガー３とが係合する際の衝撃音をなくすようにしている。
なお、キャッチ部材４は、戸先側に上方に突出する突片４２を有し、係合時には、この突片４２の内側にトリガー３の押片３１が入る。
そして、この状態でダンパー１の付勢力が働くことにより、キャッチ部材４の突片４２がトリガー３の押片３１を押し、引戸が閉じ方向に移動する。 On the other hand, the catch member 4 is pivotally supported by the base 24 on the slider 2 as shown in FIG. 4B, and engages with the trigger 3 on the door frame side to engage the guide rail 8. It moves away from the trigger 3 by moving over and falling over at the end 81 of the guide rail 8.
The catch member 4 that has fallen is hooked on the end 81 of the guide rail 8, and stops at that position against the urging force of the damper 1 while maintaining the fallen posture.
Then, as shown in FIG. 4A, the catch member 4 is raised and engaged with the trigger 3 when the push piece 31 of the trigger 3 is engaged with the tail portion 41 of the catch member 4 that has been raised by falling. It is like that.
In this case, in this embodiment, the latching portion 32 of the pressing piece 31 of the trigger 3 is formed as an arcuate (semicircular) concave portion.
As a result, when the catch member 4 is raised, the protruding tail portion 41 of the catch member 4 is smoothly guided by the arc-shaped recess so as to eliminate an impact sound when the catch member 4 and the trigger 3 are engaged. Yes.
Note that the catch member 4 has a protruding piece 42 protruding upward on the door end side, and the pushing piece 31 of the trigger 3 enters inside the protruding piece 42 when engaged.
In this state, the biasing force of the damper 1 acts, so that the projecting piece 42 of the catch member 4 pushes the pushing piece 31 of the trigger 3 and the sliding door moves in the closing direction.

かくして、本実施例の引戸の自動閉止装置は、引戸上部に配設され引戸を閉止方向に付勢するダンパー１と、該ダンパー１のロッド１ａに配設されたスライダ２と、該スライダ２と対峙するように戸枠側に設けられたトリガー３と、スライダ２に設けられ、所定の開放位置でトリガー３と係脱するキャッチ部材４とを備え、引戸を所定の開放位置から閉止位置まで自動的に閉じるようにした引戸の自動閉止装置において、スライダ２を引戸の開き方向に付勢してダンパー１の付勢力を減衰するばね部材５をダンパー１に対して並設することから、このばね部材５によってダンパー１の大きすぎる力を減衰して、引戸を最初に開けるときに要する力を軽減し、この開き始めに要する力と、所定の開放位置でキャッチ部材４がトリガー３から離脱した後に要する力との差を小さくすることができ、また、装置全体の大きさが長大になるのを防止することができる。   Thus, the sliding door automatic closing device of the present embodiment includes a damper 1 disposed on the sliding door and biasing the sliding door in the closing direction, a slider 2 disposed on the rod 1a of the damper 1, and the slider 2. A trigger 3 provided on the door frame side so as to face each other and a catch member 4 provided on the slider 2 that engages and disengages the trigger 3 at a predetermined opening position, and automatically slides the sliding door from the predetermined opening position to the closing position. In the automatic closing device for a sliding door that is closed automatically, a spring member 5 that urges the slider 2 in the opening direction of the sliding door to attenuate the urging force of the damper 1 is provided in parallel with the damper 1. The excessive force of the damper 1 is attenuated by the member 5 to reduce the force required to open the sliding door for the first time, and the catch member 4 is detached from the trigger 3 at the predetermined opening position. The difference between the force required can be reduced to after, also it can be the size of the entire apparatus is prevented from becoming long.

また、ばね部材５の固定側端部に、ばね部材５の張力を調整するばね調整ねじ７を設けることにより、引戸の重量に合わせてダンパー１の力を調節し、重い引戸でも閉じるようにしたり、軽い引戸でもゆっくりと閉じるようにすることができる。   Further, by providing a spring adjusting screw 7 for adjusting the tension of the spring member 5 at the fixed side end of the spring member 5, the force of the damper 1 is adjusted according to the weight of the sliding door, and even a heavy sliding door can be closed. Even a light sliding door can be closed slowly.

また、キャッチ部材４がスライダ２に揺動可能に枢支され、トリガー３と係合することによりガイドレール８上を移動し、ガイドレール８の終端８１で転倒することによりトリガー３から離脱するとともに、転倒することにより上昇したキャッチ部材４の尾部４１をトリガー３の押片３１で掛止することによりキャッチ部材４を起こすように構成し、前記トリガー３の押片３１の掛止部３２を円弧状の凹部として形成することにより、キャッチ部材４が起きるときにその尾部４１を円弧状の凹部で案内することができ、これにより、キャッチ部材４とトリガー３とが係合する際の衝撃音をなくすことができる。   Further, the catch member 4 is pivotally supported by the slider 2, moves on the guide rail 8 by engaging with the trigger 3, and disengages from the trigger 3 by falling over at the end 81 of the guide rail 8. The catch member 4 raised by falling is hooked by the pushing piece 31 of the trigger 3 so that the catch member 4 is raised, and the catching portion 32 of the pushing piece 31 of the trigger 3 is made circular. By forming it as an arc-shaped recess, the tail 41 can be guided by the arc-shaped recess when the catch member 4 is raised, so that an impact sound when the catch member 4 and the trigger 3 are engaged is generated. Can be eliminated.
