Description

本発明は、緩衝閉鎖装置、詳しくは手動で開閉する引戸などのスライド式建具に使用するものであって、引戸の閉鎖前の所定の範囲において引戸の速度を緩和し、またその範囲内では引戸を自動的に引き込み閉鎖させる緩衝閉鎖装置に関するものである。   The present invention is used for a shock-absorbing device, more specifically, a sliding type door such as a sliding door that is manually opened and closed. The sliding door speed is reduced within a predetermined range before the sliding door is closed, and the sliding door is within that range. The present invention relates to a buffer closing device that automatically retracts and closes.

従来、引戸を閉鎖する時に発生する衝撃を緩和し、さらにはね返り現象を無くす手段としてダンパーを用いる緩衝装置が提案されている（例えば、特許文献１）。この緩衝装置はピストンとシリンダーとを有するタイプのバンパーは内部のエアーを排出する流量を調整するようになっている。また、シリンダーの内面にバイパス溝を形成し断面積を変化させた緩衝装置も提案されている（例えば、特許文献２）。   Conventionally, a shock absorber using a damper has been proposed as means for mitigating the impact generated when closing a sliding door and eliminating the rebound phenomenon (for example, Patent Document 1). The bumper of this type having a piston and a cylinder adjusts the flow rate for discharging the internal air. In addition, a shock absorber in which a bypass groove is formed on the inner surface of the cylinder to change the cross-sectional area has been proposed (for example, Patent Document 2).

実開平６−１６７６号公報Japanese Utility Model Laid-Open No. 6-1676 特開２００６−２１９９３６号公報JP 2006-219936 A

本発明が解決しようとする問題点は、前者の緩衝装置では排出流量を調整する方法は調整が難しく、引戸が閉じきらなかったり、閉じるのに長い時間を要したりすることがあり、後者のシリンダー内面に断面積を変化させるバイパス溝を形成した緩衝装置では、建具を閉鎖するまでの時間を短縮することはできるが、建具の重量や速度によって緩衝効果が異なるため、設定によっては建具が枠体に衝突する問題があった。   The problem to be solved by the present invention is that the method of adjusting the discharge flow rate is difficult to adjust with the former shock absorber, and the sliding door may not be completely closed or may take a long time to close. The shock absorber with a bypass groove that changes the cross-sectional area on the inner surface of the cylinder can shorten the time to close the joinery, but the cushioning effect differs depending on the weight and speed of the joinery. There was a problem of colliding with the body.

本発明は、上記問題点を解決し、引戸を閉じる際の速度に柔軟に対応して緩衝機構を使い分け引戸が枠体に衝突することなく緩衝効果を発揮することができるとともに、閉鎖時間も短縮することができる緩衝閉鎖装置を提供することを課題とする。   The present invention solves the above-mentioned problems, uses a buffer mechanism flexibly corresponding to the speed when closing the sliding door, can exhibit a buffering effect without the sliding door colliding with the frame, and shortens the closing time It is an object of the present invention to provide a buffer closing device that can be used.

（二）上記第１のダンパーと第２のダンパーとは連結部材で連結され、該連結部材には第１のダンパーと第２のダンパーとに連通する連通孔が形成されるとともに、第２のダンパーには外部に連通する連通路が形成され、該連通路の断面積は上記連通孔の断面積よりも小さくしたこと
（ホ）上記閉鎖手段は、上記受け部材を後方に移動するように付勢する付勢部材で構成されていること In order to solve the above-mentioned problems, a buffer closing device according to the present invention has the following requirements.
(B) The apparatus main body is provided at the upper end of the sliding joinery, and the engaging member that engages with the apparatus main body is fixed to the head of the frame that supports the sliding joinery. And (c) a buffering means that operates by engaging with the engaging member and relaxes the speed of the sliding joinery, and a closing means that automatically retracts and closes the sliding joinery. A receiving member that is slidable forward and backward at a front portion of the main body, and that engages with the engaging member when the sliding joinery slides in a closing direction; and a first damper that operates in conjunction with the receiving member; (2) The first damper and the second damper are connected by a connecting member, and the connecting member includes a buffer mechanism configured by a second damper biased by the biasing member. For the first damper and the second damper A communication hole is formed, and a communication path communicating with the outside is formed in the second damper, and the cross-sectional area of the communication path is smaller than the cross-sectional area of the communication hole. Consists of a biasing member that biases the receiving member to move backward

なお、前記第２のダンパーに形成された外部に連通する連通路は、互いに連通する第１と第２の連通路からなり、第２の連通路は第１の連通路の延長上に形成され、かつその断面積は上記第１の連通路の断面積より小さくされるのが好ましい。   The communication path that is formed in the second damper and communicates with the outside includes a first communication path and a second communication path that communicate with each other, and the second communication path is formed on an extension of the first communication path. The cross-sectional area is preferably smaller than the cross-sectional area of the first communication path.

また、前記閉鎖手段は、一端が上記受け部材に固定され、他端が装置本体の後部に固定された付勢部材で構成されていればよい。   Moreover, the said closing means should just be comprised with the urging member by which one end was fixed to the said receiving member and the other end was fixed to the rear part of the apparatus main body.

さらに、前記閉鎖手段は、一端が上記第１のダンパーと受け部材との間に回動自在に設けられた結合部に固定され、他端が装置本体の後部に固定された付勢部材で構成するのが好ましい。   Further, the closing means is constituted by an urging member having one end fixed to a coupling portion rotatably provided between the first damper and the receiving member and the other end fixed to the rear portion of the apparatus main body. It is preferable to do this.

また、前記第１のダンパーと前記第２のダンパーとは並列又は直列の何れか一方で前記装置本体内に配置されていればよい。   The first damper and the second damper may be arranged in the apparatus main body either in parallel or in series.

本発明によれば、建具を低速で閉めた場合は、第１のシリンダーから押し出され連通孔を経由して第２のシリンダーに流入し、第２のシリンダーの連通路から外部に逃げる空気の流速が遅いため、流動抵抗による圧力の発生も低く第２のピストンを作動させることなくスムーズに閉めることができ、建具を高速で閉めた場合は、第１のシリンダーから押し出され連通孔を経由して第２のシリンダーの連通路から外部に逃げる空気の流速が速いため、流動抵抗により高い圧力が発生し、第２のピストンが作動して建具のスライドは一旦停止させられるので扉と枠体との衝突音が発生することがなく、さらに指挟み等の事故の発生を回避することができる緩衝閉鎖装置を提供することができる。   According to the present invention, when the joinery is closed at a low speed, the flow velocity of the air that is pushed out from the first cylinder, flows into the second cylinder through the communication hole, and escapes to the outside from the communication path of the second cylinder. Because the pressure is slow, the pressure generated by the flow resistance is low and can be closed smoothly without operating the second piston. When the fitting is closed at high speed, it is pushed out of the first cylinder and passes through the communication hole. Since the flow velocity of air escaping to the outside from the communication path of the second cylinder is high, high pressure is generated due to flow resistance, and the second piston is activated to stop the sliding of the joinery. It is possible to provide a buffer closing device that does not generate a collision sound and that can avoid an accident such as a finger pinching.

しかも、緩衝閉鎖装置を備えた引戸を既存の枠体に設置するときは、枠体に係合部材を取り付けるだけで済むので、枠体側には特別な工事をすることなく設置できるので、既存の建物に簡単にセッティングすることができる。   Moreover, when installing a sliding door equipped with a buffer closing device on an existing frame, it is only necessary to attach an engaging member to the frame, so it can be installed on the frame without any special construction. Can be easily set in the building.

図１は、本発明に係る緩衝閉鎖装置の一例を示すもので、この緩衝閉鎖装置は、スライド式建具（以下、引戸という）Ｄの上端に取り付けられ、引戸から上方に突出した部分は引戸Ｄの戸首Ｄ１と同一形状に形成された装置本体１と、引戸Ｄを支持する枠体の鴨居Ｆに固定される係合部材２とで構成されている。   FIG. 1 shows an example of a buffer closing device according to the present invention. This buffer closing device is attached to the upper end of a sliding fitting (hereinafter referred to as a sliding door) D, and the portion protruding upward from the sliding door is the sliding door D. The apparatus main body 1 formed in the same shape as the door nose D1 and the engaging member 2 fixed to the headquarter F of the frame that supports the sliding door D are configured.

上記係合部材２は上部が前後に延出するとともに後述する受け部材５の係合凹部２０が係合する係合突部２ａを下方に突出させた側面視略Ｔ字状に形成され、鴨居Ｆの鴨居溝にネジなどの適宜手段で固定できるようになっている。   The engaging member 2 is formed in a substantially T-shape in a side view in which an upper portion extends forward and backward and an engaging protrusion 2a engaged with an engaging recess 20 of a receiving member 5 described later is protruded downward. It can be fixed to the F Kamoi groove by appropriate means such as screws.

装置本体１は、図２に示すように、上記係合部材２に係合して作動し引戸Ｄの速度を緩和する緩衝手段Ａと、引戸Ｄを自動的に引き込み閉鎖させる閉鎖手段Ｂとで構成され、本体ケース３の内部に収容されている。なお、本体ケース３の上部には係合部材２の係合凸部２ａが通過できるよう凹溝３ａが形成されている。   As shown in FIG. 2, the apparatus main body 1 includes a buffer means A that engages with the engaging member 2 and operates to reduce the speed of the sliding door D, and a closing means B that automatically retracts and closes the sliding door D. It is comprised and is accommodated in the inside of the main body case 3. A concave groove 3a is formed in the upper part of the main body case 3 so that the engaging convex portion 2a of the engaging member 2 can pass therethrough.

緩衝手段Ａは、図３に示すように、本体ケース３の前部に前後にスライド可能に配置され、上記引戸Ｄが閉じ方向にスライドするとき上記係合部材２に係合する受け部材５と、この受け部材５にピストンロッド６の一端が結合部７を介して連結された第１のピストン１１と第１のシリンダー１２とからなる第1のダンパー１０と、この第１のダンパー１０に平行に配設され、付勢部材１３で上記第１のピストン１１に対向する方向に付勢された第２のピストン１６と第２のシリンダー１７とからなる第２のダンパー１５とで構成されている。   As shown in FIG. 3, the buffering means A is slidably arranged in the front part of the main body case 3, and receives the receiving member 5 that engages with the engaging member 2 when the sliding door D slides in the closing direction. A first damper 10 comprising a first piston 11 and a first cylinder 12 having one end of a piston rod 6 connected to the receiving member 5 via a coupling portion 7, and parallel to the first damper 10. And a second damper 15 comprising a second piston 16 and a second cylinder 17 urged by a biasing member 13 in a direction opposite to the first piston 11. .

上記受け部材５は、略逆三角形状の板部材で上面の中央には上記係合部材２の係合突部２ａに係合する係合凹部２０が形成され、この係合凹部２０の前後と下方の両側面にはそれぞれ係合軸２１、２２、２３が側方に突出して形成されている。   The receiving member 5 is a plate member having a substantially inverted triangular shape, and an engaging recess 20 is formed at the center of the upper surface to be engaged with the engaging protrusion 2a of the engaging member 2. Engagement shafts 21, 22, and 23 are formed on both lower side surfaces so as to protrude laterally.

上記係合軸２１、２２は本体ケースの長手方向に形成された第１の案内溝２５に案内され、係合軸２３は上記第１の案内溝２５の下方に平行に形成された第２の案内溝２６に案内され、本体ケース３内を前後にスライド移動できるようになっている。   The engagement shafts 21 and 22 are guided by a first guide groove 25 formed in the longitudinal direction of the main body case, and the engagement shaft 23 is a second portion formed in parallel below the first guide groove 25. Guided by the guide groove 26, the body case 3 can be slid back and forth.

なお、上記第１の案内溝２５は前部が第２の案内溝２６よりも前方に延出するとともに、前端が下方に曲折して曲折部２５ａを形成しているので、係合軸２３が第２の案内溝２６の先端に位置するときには、受け部材５は係合軸２３を中心に前方に回動し、係合軸２１が第１の案内溝２５の曲折部２５ａに位置して係合凹部２０が前方を向くようになっている（図３参照）。   The first guide groove 25 has a front portion extending forward from the second guide groove 26 and a front end bent downward to form a bent portion 25a. When positioned at the tip of the second guide groove 26, the receiving member 5 rotates forward about the engagement shaft 23, and the engagement shaft 21 is positioned at the bent portion 25 a of the first guide groove 25. The joint recess 20 faces forward (see FIG. 3).

そして、第２の案内溝２６に案内される第３の係合軸２３にはピストンロッド６の先端が結合部７を介して連結されている。また、上記第３の係合軸２３の下方には、後述する閉鎖手段Ｂを構成するコイルスプリング４０の一端を引っ掛ける支持軸２７が形成されている。   The tip of the piston rod 6 is connected to the third engagement shaft 23 guided by the second guide groove 26 via the coupling portion 7. A support shaft 27 is formed below the third engagement shaft 23 to hook one end of a coil spring 40 that constitutes a closing means B described later.

第１のダンパー１０は第１のシリンダー１２と第１のピストン（メインピストン）１１とで構成された直動型ダンパーで、第１のピストン１１のピストンロッド６の先端は上述したように、受け部材５に連結されているので、受け部材５と一体で作動するようになっている。   The first damper 10 is a linear motion type damper composed of a first cylinder 12 and a first piston (main piston) 11, and the tip of the piston rod 6 of the first piston 11 is received as described above. Since it is connected to the member 5, it operates integrally with the receiving member 5.

第２のダンパー１５は、上記第１のダンパー１０と平行に配置され、第２のシリンダー１７と付勢部材であるコイルバネ１３で付勢された第２のピストン（フリーピストン）１６とで構成された直動型ダンパーで、上記第２のピストン１６には第２のシリンダー１７の内壁に密着するシールリング３０が設けられている。なお、第２のシリンダー１７には外部に連通するスリットで構成された連通路３１（以下、スリットという）が形成されている。   The second damper 15 is arranged in parallel with the first damper 10 and includes a second cylinder 17 and a second piston (free piston) 16 biased by a coil spring 13 that is a biasing member. The second piston 16 is provided with a seal ring 30 that is in close contact with the inner wall of the second cylinder 17. The second cylinder 17 is formed with a communication path 31 (hereinafter referred to as a slit) constituted by a slit communicating with the outside.

上記第１のダンパー１０と第２のダンパー１５とは連結部材３５で連結され、この連結部材３５には第１のシリンダー１２と第２のシリンダー１７とを連通させる連通孔３６が形成され、第１のピストン１１が作動して圧縮された第１のシリンダー１２内の空気は連通孔３６を経由して第２のシリンダー１７内に流入し、さらにスリット３１を経由して第２のピストン１６の後方に流れるようになっている。   The first damper 10 and the second damper 15 are connected by a connecting member 35, and the connecting member 35 is formed with a communication hole 36 for communicating the first cylinder 12 and the second cylinder 17. The air in the first cylinder 12 compressed by the operation of the first piston 11 flows into the second cylinder 17 through the communication hole 36, and further flows through the slit 31 to the second piston 16. It is designed to flow backwards.

なお、連結部材３５に形成された連通孔３６の断面積に対し、第２のシリンダー１７に形成されたスリット３１の断面積は小さく設定されているので、第１のピストン１１がゆっくり作動するときは第１のシリンダー１２内の空気は連結孔３６から第２のシリンダー１７内に流入し、さらにスリット３１から外部に高い圧力を発生することなく放出されるので、流入した空気で第２のダンパー１５は作動することはないが、第１のピストン１１が速く作動するときは第１のシリンダー１２内の空気は連結孔３６から第２のシリンダー１７内に短時間に多くの空気が流入することになり、スリット３１から外部に放出される空気の流動抵抗により高い圧力が発生し、第２のピストン１６がコイルバネ１３に抗して押し込まれ、第２のダンパーが作動することになっている。   In addition, since the cross-sectional area of the slit 31 formed in the second cylinder 17 is set smaller than the cross-sectional area of the communication hole 36 formed in the connecting member 35, the first piston 11 operates slowly. Since the air in the first cylinder 12 flows into the second cylinder 17 from the connecting hole 36 and is released from the slit 31 without generating high pressure to the outside, the second damper 15 does not operate, but when the first piston 11 operates fast, the air in the first cylinder 12 flows into the second cylinder 17 from the connecting hole 36 in a short time. Therefore, a high pressure is generated by the flow resistance of the air discharged from the slit 31 to the outside, the second piston 16 is pushed against the coil spring 13, and the second damper is It is supposed to be dynamic.

閉鎖手段Ｂはコイルスプリング４０（以下、引張りバネという）で構成され、一端は上述したように、受け部材５の支持軸２７に引っ掛けられ、他端は本体ケース３の後部に形成された支持軸４１に引っ掛けられ、図３に示すように、受け部材５の係合軸２１が第１の案内溝２５の曲折部２５ａに位置しているときには、引張りバネ４０は最大に伸張した状態になっている。   The closing means B is constituted by a coil spring 40 (hereinafter referred to as a tension spring), one end is hooked on the support shaft 27 of the receiving member 5 as described above, and the other end is a support shaft formed at the rear part of the body case 3. When the engaging shaft 21 of the receiving member 5 is positioned at the bent portion 25a of the first guide groove 25 as shown in FIG. Yes.

次に、上記構成の緩衝閉鎖装置の作動態様について説明する。図４に示すように、引戸Ｄが開いている状態では、受け部材５は前方に回動して係合凹部２０が前方に開口しているので、引戸Ｄを閉じ方向にスライドさせて、図５（ａ）に示すように、係合部材２の係合突部２ａに受け部材５の係合凹部２０が衝突する位置までスライドさせると、図５（ｂ）に示すように、受け部材５は時計方向に強制的に回動させられる。受け部材５が回動すると係合軸２１が第１の案内溝２５の曲折部２５ａから開放されるので、受け部材５は第１の案内溝２５に係合軸２１、２２が案内され、第２の案内溝２６に係合軸２３が案内されてケース本体３内を後方に移動できる状態になる。この状態では引張りバネ４０が収縮できる状態になり、受け部材５が引張りバネ４０に引張られて案内溝２５、２６の端部まで強制的に移動させられることになる。しかし、受け部材５は係合凹部２０が係合部材２の係合突部２ａに係合しているので、受け部材５は実際は移動できないため、相対的にケース本体３が引張られることになる（図５（ｃ）参照）。   Next, an operation mode of the buffer closing device having the above-described configuration will be described. As shown in FIG. 4, in a state where the sliding door D is open, the receiving member 5 is rotated forward and the engaging recess 20 is opened forward. Therefore, the sliding door D is slid in the closing direction, As shown in FIG. 5 (a), when the engagement protrusion 2a of the engagement member 2 is slid to the position where the engagement recess 20 of the reception member 5 collides with the engagement protrusion 2a, as shown in FIG. Is forcibly rotated clockwise. When the receiving member 5 rotates, the engaging shaft 21 is released from the bent portion 25a of the first guide groove 25, so that the receiving member 5 is guided to the first guiding groove 25 by the engaging shafts 21 and 22, and the first The engaging shaft 23 is guided by the two guide grooves 26 so that the inside of the case body 3 can be moved rearward. In this state, the tension spring 40 can be contracted, and the receiving member 5 is pulled by the tension spring 40 and is forcibly moved to the ends of the guide grooves 25 and 26. However, since the receiving concave portion 20 of the receiving member 5 is engaged with the engaging protrusion 2a of the engaging member 2, the receiving member 5 cannot actually move, so that the case body 3 is relatively pulled. (See FIG. 5 (c)).

ケース本体３は引戸Ｄに固定されているため、結果として引戸Ｄが閉じ方向に引き込まれ引戸が閉じられることになる。   Since the case body 3 is fixed to the sliding door D, as a result, the sliding door D is pulled in the closing direction and the sliding door is closed.

この時、引戸Ｄを低速で閉じる場合は、第１のピストン１１がシリンダー１２に対して後方に移動させられてシリンダー１２内の空気が連通孔３６を介して、第２のシリンダー１７に送り込まれ、第２のシリンダー１７のスリット３１から放出される空気の流速が遅いことにより、ここでの流動抵抗による圧力の発生が低いため、送り込まれた空気は少しずつ放出され、そのまま低速で移動することにより引戸Ｄが弱く閉じられる。   At this time, when the sliding door D is closed at a low speed, the first piston 11 is moved rearward with respect to the cylinder 12, and the air in the cylinder 12 is sent into the second cylinder 17 through the communication hole 36. Since the flow rate of the air discharged from the slit 31 of the second cylinder 17 is slow, the pressure generated by the flow resistance here is low, so the fed air is released little by little and moves at a low speed as it is. Thus, the sliding door D is closed weakly.

一方、引戸Ｄを高速で閉じた場合は、低速の場合と同様に第１のピストン１１がシリンダー１２に対して後方に移動させられてシリンダー１２の空気が連通孔３６を介して、第２のシリンダー１７に送り込まれるが、第１のピストン１１が速く作動させられるため第１のシリンダー１２内の空気は連結孔３６から第２のシリンダー１７内に短時間に多くの空気が流入することになり、スリット３１から外部に放出される空気の流速が速くなり流動抵抗により高い圧力が発生し、第２のピストン１６がコイルバネ１３に抗して押し込まれ第２のダンパー１５が作動する。   On the other hand, when the sliding door D is closed at a high speed, the first piston 11 is moved rearward with respect to the cylinder 12 as in the case of the low speed, and the air in the cylinder 12 passes through the communication hole 36 to the second. Although it is fed into the cylinder 17, the first piston 11 is operated quickly, so that a large amount of air flows from the connecting hole 36 into the second cylinder 17 in a short time. The flow rate of the air discharged from the slit 31 increases, and a high pressure is generated due to the flow resistance. The second piston 16 is pushed against the coil spring 13 and the second damper 15 operates.

ここで押し込まれた第２のピストン１６がスリット３１の位置から後退することにより、第1のピストン１１と第２のピストン１６の間の空気は逃げることができず閉塞状態になるので、第１のピストン１１の移動は阻止されて引戸Ｄが一旦停止することになる（図６（ａ）参照）。   Since the second piston 16 pushed in here retreats from the position of the slit 31, the air between the first piston 11 and the second piston 16 cannot escape and becomes closed. The movement of the piston 11 is prevented, and the sliding door D is temporarily stopped (see FIG. 6A).

一旦停止した後は第２のピストン１６がコイルバネ１３の付勢力によって徐々に押し戻され、図６（ｂ）に示すように、スリット３１の範囲内にシールリング３０が戻ることにより、矢印ａに示すように、空気はスリット３１から第２のピストン１６の後方に流れ始め、引戸Ｄは引張りバネ４０の引張り力でゆっくり閉じられることになる。   After stopping once, the second piston 16 is gradually pushed back by the urging force of the coil spring 13, and as shown in FIG. As described above, air begins to flow from the slit 31 to the rear of the second piston 16, and the sliding door D is slowly closed by the tension force of the tension spring 40.

そして、引戸Ｄを開く場合は、受け部材５が係合部材２に係合した状態（図５（ｃ）参照）で、装置本体１が矢印と逆方向（図面上で右方向）に移動することになり、図５（ｂ）に示すように引張りバネ４０を引き伸ばしながら、係合軸２１、２２が第1の案内溝２５に、係合軸２３が第2の案内溝２６に案内されて案内溝の先端に向かって移動することになる。   When the sliding door D is opened, the apparatus main body 1 moves in the direction opposite to the arrow (rightward in the drawing) with the receiving member 5 engaged with the engaging member 2 (see FIG. 5C). Thus, as shown in FIG. 5B, while the tension spring 40 is stretched, the engagement shafts 21 and 22 are guided to the first guide groove 25 and the engagement shaft 23 is guided to the second guide groove 26. It moves toward the tip of the guide groove.

係合軸２３が第2の案内溝２６の先端に到達した後、さらに引戸Ｄが開き方向に移動すると、係合軸２１は第1の案内溝２５の曲折部２５ａに移動して受け部材５が反時計方向に回動させられ、係合部材２と受け部材５との係合が外れる。この時、受け部材５の下部に設けられた支持軸２７が引張りバネ４０で引かれているので受け部材５は係合軸２３を中心に回動し、係合軸２１が第1の案内溝２５の曲折部２５ａに移動した状態でロックされ、引張りバネ４０は最大伸張した状態になり、引戸Ｄが再び閉じられるまでこの状態が維持される（図３参照）。   When the sliding door D further moves in the opening direction after the engagement shaft 23 reaches the tip of the second guide groove 26, the engagement shaft 21 moves to the bent portion 25 a of the first guide groove 25 and receives the receiving member 5. Is rotated counterclockwise, and the engagement member 2 and the receiving member 5 are disengaged. At this time, since the support shaft 27 provided at the lower portion of the receiving member 5 is pulled by the tension spring 40, the receiving member 5 rotates about the engaging shaft 23, and the engaging shaft 21 is the first guide groove. The tension spring 40 is locked in a state where it has been moved to the bent portion 25a of 25, and the tension spring 40 is in a fully extended state, and this state is maintained until the sliding door D is closed again (see FIG. 3).

上述したように、低速で引戸Ｄを閉める場合は、緩衝装置はほとんど働かず、閉鎖装置が働いてゆっくりと引戸Ｄを閉じることができ、高速で引戸Ｄを閉める場合は、緩衝装置が働いて引戸Ｄを一旦停止させ、その後閉鎖装置が働いてゆっくりと閉じることができ、引戸Ｄが枠体に激しく当たって大きな音を出したり、指を挟むなどのトラブルが発生したりすることがなく、使い勝手のよい、緩衝閉鎖装置を実現することができる。   As described above, when the sliding door D is closed at a low speed, the shock absorber hardly works, the closing device works so that the sliding door D can be closed slowly, and when the sliding door D is closed at a high speed, the shock absorber works. The sliding door D is temporarily stopped, and then the closing device works so that it can be closed slowly, and the sliding door D does not hit the frame body and make a loud noise or cause troubles such as pinching fingers. An easy-to-use buffer closing device can be realized.

しかも、装置本体の引戸Ｄの上部から上方に突出する部分は引戸Ｄの戸首と同じ形状にしたので、緩衝閉鎖装置を備えた引戸Ｄを既存の引戸と入れ替える場合は係合部材２のみを鴨居溝に取り付けるだけで済み、作業性にも優れた緩衝閉鎖装置を提供することができる。   And since the part which protrudes upwards from the upper part of the sliding door D of an apparatus main body was made into the same shape as the neck of the sliding door D, when replacing the sliding door D provided with the buffer closing device with the existing sliding door, only the engaging member 2 is used. It is only necessary to attach to the Kamoi groove, and a buffer closing device excellent in workability can be provided.

なお、上述した緩衝閉鎖装置では、第１のダンパー１０と第２のダンパー１５とは並列に配置された場合について説明したが、この２つのダンパー１０、１５の配置は並列に限定されるものではなく、図７に示すように、直列に配置し、連結部材３５を介して第１のピストン１１と第２のピストン１６とが対向するように配置しても構わない。   In the above-described buffer closing device, the case where the first damper 10 and the second damper 15 are arranged in parallel has been described. However, the arrangement of the two dampers 10 and 15 is not limited to being arranged in parallel. Alternatively, as shown in FIG. 7, the first piston 11 and the second piston 16 may be arranged in series so that the first piston 11 and the second piston 16 face each other with the connecting member 35 interposed therebetween.

また、閉鎖手段Ｂは引張りバネ４０で構成したが、この閉鎖手段Ｂは、図８に示すように、装置本体１の後部にゼンマイバネ５１を収容したゼンマイユニット５０を併設し、このゼンマイ５１にワイヤー５２を連結し、このワイヤー５２の先端を、受け部材５の支持軸２７に取り付け、このゼンマイバネ５１の巻き戻り力で、引張りバネ４０の引張り力に代えても構わない。   Further, the closing means B is constituted by the tension spring 40. However, as shown in FIG. 52, the tip of the wire 52 may be attached to the support shaft 27 of the receiving member 5, and the rewinding force of the mainspring spring 51 may be replaced with the tensile force of the tension spring 40.

さらに、図９に示すように、閉鎖手段Ｂを引張りバネ４０やゼンマイユニット５０に代えて、クローザー５５で構成してもよい。このクローザー５５は公知のクローザーで構成されていればよく、クローザー５５の上部は、係合部材２の係合凸部２ａが通過できるように凹溝５６を形成し、クローザー５５に巻き込まれるワイヤー５７の先端にはワイヤー係止部材５８を取り付け、このワイヤー係止部材５８は上述の係合部材２と同様に、鴨居溝に固定されていればよい。   Further, as shown in FIG. 9, the closing means B may be constituted by a closer 55 instead of the tension spring 40 and the mainspring unit 50. The closer 55 only needs to be formed of a known closer, and the upper portion of the closer 55 is formed with a concave groove 56 so that the engaging convex portion 2a of the engaging member 2 can pass therethrough. A wire locking member 58 is attached to the tip of the wire, and the wire locking member 58 may be fixed to the Kamoi groove in the same manner as the engagement member 2 described above.

次に、上記緩衝閉鎖装置の内部構成の他の形態の緩衝閉鎖装置について説明する（図１０（ａ）（ｂ）参照）。
この緩衝閉鎖装置は、具体的には受け部材５の係合軸２３が側方に突出して上記第２の案内溝２６に案内されることで該受け部材５が前後にスライド移動できるようにした構成部分と、受け部材５の支持軸２７に固定された閉鎖手段Ｂを構成する引張りバネ４０の一端の固定場所と、さらに第２のシリンダー１７に形成された外部に連通する連通路であるスリット３１の構成部分において上述の実施形態とは異なる。 Next, another embodiment of the buffer closing device having the internal configuration of the buffer closing device will be described (see FIGS. 10A and 10B).
Specifically, the buffer closing device is configured such that the receiving member 5 can slide back and forth by the engagement shaft 23 of the receiving member 5 projecting sideways and guided by the second guide groove 26. A slit that is a communication path communicating with the component, the fixing place of one end of the tension spring 40 constituting the closing means B fixed to the support shaft 27 of the receiving member 5, and the outside formed in the second cylinder 17. 31 components are different from the above-described embodiment.

すなわち、図１０（ａ）（ｂ）に示されるように、受け部材５の上述の係合軸２３に対応する連結軸２４が側方に突出する部分を有しない軸として形成され、また、上述の係合軸２３を案内する上記第２の案内溝２６に相当する溝を不要としており、受け部材５の支持軸２７に固定された引張りバネ４０の一端は、受け部材５の支持軸２７ではなく、ピストンロッド６の一端の結合部７の側方で突出する突出部７ａの支持軸７ｂに固定されている。   That is, as shown in FIGS. 10 (a) and 10 (b), the connecting shaft 24 corresponding to the engaging shaft 23 of the receiving member 5 is formed as a shaft that does not have a portion protruding sideways. A groove corresponding to the second guide groove 26 for guiding the engagement shaft 23 is unnecessary, and one end of the tension spring 40 fixed to the support shaft 27 of the receiving member 5 is not supported by the support shaft 27 of the receiving member 5. Instead, the piston rod 6 is fixed to the support shaft 7b of the protruding portion 7a protruding from the side of the coupling portion 7 at one end.

さらに、第２のシリンダー１７には該シリンダー１７に形成されたスリット３１の延長上に第２のスリット３２（第２の連通路）を形成し、第２のスリット３２はスリット３１の延長上に連続して第２のシリンダー１７の長手方向に延長形成されている。第２のスリット３２の断面積はスリット３１の断面積より小さく設定されている。   Further, the second cylinder 17 is formed with a second slit 32 (second communication path) on the extension of the slit 31 formed in the cylinder 17, and the second slit 32 is on the extension of the slit 31. The second cylinder 17 is continuously extended in the longitudinal direction. The sectional area of the second slit 32 is set smaller than the sectional area of the slit 31.

上記緩衝閉鎖装置においては、受け部材５の連結軸２４は溝に案内されることはなく、また、引張りバネ４０の一端はピストンロッド一端の結合部７の支持軸７ｂに固定されているので、受け部材５は引張りバネ４０の引張り力による回動力を直接受けることはない。   In the buffer closing device, the connecting shaft 24 of the receiving member 5 is not guided by the groove, and one end of the tension spring 40 is fixed to the support shaft 7b of the coupling portion 7 at one end of the piston rod. The receiving member 5 does not directly receive the rotational force due to the tensile force of the tension spring 40.

したがって、受け部材５の運動の許容度は増大され、これにより、引戸Ｄを開いた状態でロックするための第１の案内溝２５に案内される受け部材５の係合軸２１、２２の移動は摺動摩擦が軽減されてスムーズに行われる。特に係合軸２１の前端の下方に屈曲した溝内での移行はスムーズに行われ、係合軸２１は曲折部２５ａに容易に導かれて前方を向くように位置付けられて、この位置で最大に伸張した一端が結合部７の支持軸７ｂに固定された引張りバネ４０の張力を受けて固定状態にロックされ、引戸Ｄは開けた状態に維持される。   Accordingly, the tolerance of the movement of the receiving member 5 is increased, whereby the movement of the engagement shafts 21 and 22 of the receiving member 5 guided by the first guide groove 25 for locking the sliding door D in the open state. Is carried out smoothly with reduced sliding friction. In particular, the transition in the groove bent downward of the front end of the engagement shaft 21 is performed smoothly, and the engagement shaft 21 is easily guided to the bent portion 25a and positioned so as to face the front. One end of the sliding portion D is locked in a fixed state under the tension of a tension spring 40 fixed to the support shaft 7b of the coupling portion 7, and the sliding door D is maintained in an open state.

また、上記開いた状態の引戸Ｄを閉じる時にも、上記係合軸２１、２２は第１の案内溝２５内を上記同様摺動摩擦の軽減状態でスムーズに移行し、特に係合軸２１は受け部材５の時計方向への回動に伴い上記曲折部２５ａから上記案内溝２５の直線部へと容易にかつスムーズに移行される。   Further, when the sliding door D in the opened state is closed, the engagement shafts 21 and 22 smoothly move in the first guide groove 25 in the same manner as described above with reduced sliding friction. As the member 5 rotates in the clockwise direction, the bent portion 25a is easily and smoothly transferred from the bent portion 25a to the linear portion of the guide groove 25.

そして、引戸Ｄを低速で閉じた時には、第１のピストン１１がシリンダー１２に対して後方に移動させられてシリンダー１２内の空気が連通孔３６を介して、第２のシリンダー１７に送り込まれ、第２のシリンダー１７のスリット３１を経て放出される空気の流速が遅いことにより、ここでの流動抵抗による圧力の発生が低いため、送り込まれた空気は少しずつ放出され、そのまま低速で移動することにより引戸Ｄが弱く閉じられる。   When the sliding door D is closed at a low speed, the first piston 11 is moved rearward with respect to the cylinder 12, and the air in the cylinder 12 is sent to the second cylinder 17 through the communication hole 36. Since the flow rate of the air released through the slit 31 of the second cylinder 17 is slow, the pressure generated by the flow resistance here is low, so the fed air is released little by little and moves at a low speed as it is. Thus, the sliding door D is closed weakly.

一方、引戸Ｄを急激に閉じた時には、第１のピストン１１が作動して圧縮された第１のシリンダー１２内の空気は、連通孔３６を経由して第１のシリンダー１２内に流入し、さらに、スリット３１を経由して第２のピストン１６の後方に流れるようになる。そして、押し込まれた第２のピストン１６が第１のスリット３１の範囲内から後退し、第２のスリット３２の範囲内に達すると、第２のスリット３２の断面積が小さいため流動抵抗がさらに大きくなり、第１ピストン１１の移動は阻止され、引戸Ｄも一旦停止する状態となるが、第２のスリット３２からは少量の空気が連続して排出されるので完全な閉塞状態とはならず、引戸Ｄの衝撃は効果的に緩和される。   On the other hand, when the sliding door D is suddenly closed, the air in the first cylinder 12 compressed by the operation of the first piston 11 flows into the first cylinder 12 through the communication hole 36, Further, it flows behind the second piston 16 via the slit 31. Then, when the pushed second piston 16 retracts from the range of the first slit 31 and reaches the range of the second slit 32, the flow resistance is further increased because the sectional area of the second slit 32 is small. The first piston 11 is prevented from moving, and the sliding door D is also temporarily stopped. However, since a small amount of air is continuously discharged from the second slit 32, it is not completely closed. The impact of the sliding door D is effectively mitigated.

引戸Ｄが一旦停止する状態になった後は、第２のスリット３２から引き続き少量の空気が排出されるとともに、コイルバネ１３の付勢力によって第２のピストン１６が徐々に押し戻される。このため、スリット３１の範囲内にシールリング３０が戻り、空気は再び断面積の大きなスリット３１から第２のピストン１６の後方に流れて外部へと排出され、引戸Ｄは引張りバネ４０の引張り力でゆっくり閉じられる。   After the sliding door D is temporarily stopped, a small amount of air is continuously discharged from the second slit 32 and the second piston 16 is gradually pushed back by the biasing force of the coil spring 13. For this reason, the seal ring 30 returns within the range of the slit 31, the air flows again from the slit 31 having a large cross-sectional area to the rear of the second piston 16 and is discharged to the outside, and the sliding door D is pulled by the tension force of the tension spring 40. It closes slowly.

上述のように、上記緩衝閉鎖装置によれば、引張りバネ４０の一端の固定位置を受け部材５の支持軸２７から結合部７の支持軸７ｂに変更したことにより、受け部材５は引張りバネ４０の直接的な回転力を受けず、また、受け部材５はその連結軸２４が上記のような溝に案内されて拘束されるものでないから運動の許容度が大きくなり、引戸Ｄを開けた状態のロック時や引戸Ｄを閉める時の該ロック解除時の受け部材５の連結軸２４を中心とした回動は、係合軸２１の第１の案内溝２５に案内された曲折部２５ａへの、もしくは該曲折部２５ａからの移動に伴い無理なく行われ、結果として係合軸２１、２２と第１の案内溝２５との摺動抵抗の軽減効果が相俟って係合軸２１、２２と第１の案内溝２５との隙間を狭くすることができ、受け部材５と係合部材２の嵌合時の発生音を小さく抑えることができる。   As described above, according to the buffer closing device, the receiving member 5 is changed from the support shaft 27 of the member 5 to the support shaft 7b of the coupling portion 7 by changing the receiving position of the one end of the tension spring 40. The receiving member 5 is not restrained by the connecting shaft 24 being guided by the groove as described above, and the tolerance of movement is increased, and the sliding door D is opened. When the door is locked or when the sliding door D is closed, the rotation of the receiving member 5 around the connecting shaft 24 when the lock is released is applied to the bent portion 25a guided by the first guide groove 25 of the engaging shaft 21. Alternatively, it is carried out without difficulty with the movement from the bent portion 25a, and as a result, the effect of reducing the sliding resistance between the engagement shafts 21 and 22 and the first guide groove 25 is combined and the engagement shafts 21 and 22 are combined. And the first guide groove 25 can be narrowed, and the receiving portion 5 and generated sound during engagement of the engagement member 2 can be reduced.

また、スリット３１の延長上に断面積が小さく設定された第２のスリット３２を追加することにより、引戸Ｄの一旦停止後、第１のピストン１１と第２のピストン１６との間の空気は第２のスリット３２を経由して徐々に排出されているから、上記引戸Ｄの一旦停止後の第２のピストン１６のスリット３１の位置への復帰動作は、内部圧力の急激な変化の影響を受けることなく行なわれるので安定させることができる。   Further, by adding the second slit 32 having a small cross-sectional area on the extension of the slit 31, the air between the first piston 11 and the second piston 16 is temporarily stopped after the sliding door D is stopped. Since the gas is gradually discharged through the second slit 32, the return operation of the second piston 16 to the position of the slit 31 after the sliding door D is temporarily stopped is affected by a sudden change in internal pressure. Since it is performed without receiving it, it can be stabilized.

なお、上述の緩衝閉鎖装置においても、図７に示すような２つのダンパー１０、１５の直列配置を採用することができ、また閉鎖手段Ｂを図８に示すように、装置本体１の後部にゼンマイバネ５１を収容したゼンマイユニット５０を併設し、このゼンマイ５１にワイヤー５２を連結し、このワイヤー５２の先端を、結合部７の支持軸７ｂに取り付け、このゼンマイバネ５１の巻き戻り力で、引張りバネ４０の引張り力に代えても構わない。さらに、図９に示すように、閉鎖手段を引張りバネ４０やゼンマイユニット５０に代えて、クローザー５５で構成してもよい。   Also in the above-described buffer closing device, a series arrangement of two dampers 10 and 15 as shown in FIG. 7 can be adopted, and the closing means B is arranged at the rear part of the device main body 1 as shown in FIG. A mainspring unit 50 containing a mainspring 51 is provided, and a wire 52 is connected to the mainspring 51, and the tip of the wire 52 is attached to the support shaft 7 b of the coupling portion 7. It may be replaced with a pulling force of 40. Further, as shown in FIG. 9, the closing means may be constituted by a closer 55 instead of the tension spring 40 and the mainspring unit 50.
