Description

本発明は、引戸の開閉装置に係わり、更に詳しくは自閉機構を備えた引戸の開閉装置に関するものである。 The present invention relates to a sliding door opening / closing device, and more particularly to a sliding door opening / closing device provided with a self-closing mechanism.

従来から引戸枠の上部に設けたレールに、引戸の上端の戸先側と戸尻側に設けた吊車を走行可能に支持した引戸の開閉装置は各種提供されている。そして、特許文献１に示すように、引戸に常に一定の閉止力を付与して自動的に閉じることができる自閉装置を組み込んだものが提供されている。一方、特許文献２に示すように、全閉状態から一定距離の位置まで引戸を開く際に閉止方向への弾性力を蓄積し、開状態から閉止方向へ移動してきた引戸を一定距離の位置から全閉状態まで蓄積弾性力によって閉止動作を支援する引き込み装置を組み込んだものも提供されている。 Conventionally, various types of sliding door opening / closing devices have been provided in which the rails provided on the upper part of the sliding door frame are supported by the suspension vehicles provided on the door end side and the door tail side of the upper end of the sliding door so as to be able to run. Then, as shown in Patent Document 1, there is provided a sliding door incorporating a self-closing device that can always apply a constant closing force to automatically close the sliding door. On the other hand, as shown in Patent Document 2, when the sliding door is opened from the fully closed state to a position of a certain distance, elastic force in the closing direction is accumulated, and the sliding door that has moved from the open state to the closing direction is moved from the position of a certain distance. There is also one that incorporates a retracting device that supports the closing operation by the accumulated elastic force up to the fully closed state.

これら自閉装置と引き込み装置は、それぞれ利点があるが、それらを両方組み込んだ引戸の開閉装置はこれまで提供されていない。その理由として、全閉状態から引戸を開く初期動作区間で、引き込み装置と自閉装置の負荷が重なっているため、その区間では大きな開力を必要として使用勝手が悪く、使用者が非常に重く感じる。 Although these self-closing devices and retracting devices each have advantages, a sliding door opening / closing device incorporating both of them has not been provided so far. The reason is that in the initial operation section where the sliding door is opened from the fully closed state, the load of the pull-in device and the self-closing device overlap, so a large opening force is required in that section, which is not easy to use and the user is very heavy. feel.

A sliding door opening / closing device characterized in that the distance D is set short.

（２）
前記遅延機構は、引戸の移動方向に向けて連係部材を配置し、該連係部材に引戸の移動方向に延びたガイド溝を形成し、引戸に固定した作動ピンを前記ガイド溝内で前記非作動距離Ｄだけ相対的にスライド移動可能とし、前記自閉装置の作動部に前記連係部材を連結して、該連係部材を介して閉止力を引戸に伝達する構造であり、全閉状態で前記作動ピンを前記ガイド溝内の戸先側端に位置させてなる（１）記載の引戸の開閉装置。 (2)
In the delay mechanism, a linking member is arranged in the moving direction of the sliding door, a guide groove extending in the moving direction of the sliding door is formed in the linking member, and an operating pin fixed to the sliding door is not activated in the guide groove. The structure is such that the linking member can be relatively slidable by a distance D, the linking member is connected to the operating portion of the self-closing device, and the closing force is transmitted to the sliding door via the linking member. The sliding door opening / closing device according to (1), wherein the pin is located at the door end side end in the guide groove.

（３）
前記自閉装置は、引戸枠に定荷重巻きバネを固定し、該定荷重巻きバネから引き出したワイヤーからなる前記作動部の端部を前記連係部材に連結し、全閉状態から非作動距離Ｄの位置までを除き、該連係部材を介して常に一定の閉止力を引戸に伝達する構造である（２）記載の引戸の開閉装置。 (3)
In the self-closing device, a constant load winding spring is fixed to a sliding door frame, an end portion of the operating portion made of a wire drawn from the constant load winding spring is connected to the linking member, and a non-operating distance D from the fully closed state. The sliding door opening / closing device according to (2), which has a structure in which a constant closing force is always transmitted to the sliding door through the linking member except for the position of.

（４）引戸枠の上部に設けたレールに、引戸の上端の戸先側と戸尻側に設けた吊車を走行可能に支持し、前記引き込み装置は前記レールの溝内に配置するとともに、前記遅延機構を構成する連係部材は、前記引戸の上端と前記レールの間に配置してなる（２）又は（３）記載の引戸の開閉装置。 (4) The rails provided on the upper part of the sliding door frame support the suspension vehicles provided on the door end side and the door tail side of the upper end of the sliding door so as to be able to travel, and the pulling device is arranged in the groove of the rail and described as described above. The sliding door opening / closing device according to (2) or (3), wherein the linking member constituting the delay mechanism is arranged between the upper end of the sliding door and the rail.

以上にしてなる本発明の引戸の開閉装置は、以下に示す効果を奏する。 The sliding door opening / closing device of the present invention as described above has the following effects.

（１）の構成によれば、引き込み装置と自閉装置を併用したので、開放した引戸を両装置が連係して自動的に全閉状態にすることができ、また全閉状態から引戸を開く際に自閉装置は非作動距離Ｄの位置まで遅延機構によって作動を遅らせることができ、もって引戸を軽く開くことができるのである。つまり、全閉状態から引戸を開く際に、引き込み装置に閉止方向への弾性力を蓄積するが、引戸は非作動距離Ｄだけ開く間にある程度加速が付くので、この慣性力を利用することで引き込み装置と自閉装置の負荷が重なった開力の重い区間を通過させることができ、その後は自閉装置の負荷だけになるので、使用者の感覚として重く感じさせないようにすることができる。一方、全開状態若しくは途中の開状態から引戸を閉じる際には、引戸の把手から手を離せば、自閉装置による閉止力によって引戸は閉止方向へ自動的に移動するが、引き込み装置が作動した直後に自閉装置の閉止力が作用しなくなるので、ゆっくりと全閉状態まで閉じることができる。ここで、引き込み装置にダンパー機能が備わっていると、自閉装置によって加速された引戸が引き込み装置の作動と共に減速されて閉じるので、全閉時の衝撃を更に和らげることができる。また、本発明は、引戸が重量のあるガラス引戸等である場合に特に効果的である。 According to the configuration of (1), since the retracting device and the self-closing device are used together, both devices can be linked to automatically bring the opened sliding door into the fully closed state, and the sliding door can be opened from the fully closed state. At that time, the self-closing device can be delayed by the delay mechanism to the position of the non-operating distance D, so that the sliding door can be opened lightly. In other words, when the sliding door is opened from the fully closed state, elastic force in the closing direction is accumulated in the retracting device, but the sliding door accelerates to some extent while opening by the non-operating distance D, so by using this inertial force, It is possible to pass through a section where the load of the pull-in device and the self-closing device overlap and the opening force is heavy, and after that, only the load of the self-closing device is applied, so that the user does not feel heavy. On the other hand, when closing the sliding door from the fully open state or the halfway open state, if the handle of the sliding door is released, the sliding door automatically moves in the closing direction due to the closing force of the self-closing device, but the pull-in device is activated. Immediately after that, the closing force of the self-closing device does not work, so it can be slowly closed to the fully closed state. Here, if the retracting device is provided with a damper function, the sliding door accelerated by the self-closing device is decelerated and closed with the operation of the retracting device, so that the impact at the time of fully closing can be further softened. Further, the present invention is particularly effective when the sliding door is a heavy glass sliding door or the like.

（２）の構成によれば、連係部材と作動ピンを追加するだけで、全閉状態から非作動距離Ｄの位置まで引戸を開く際に自閉装置による閉止力が作用しないように遅延機構を備えさせることができる。 According to the configuration of (2), a delay mechanism is provided so that the closing force of the self-closing device does not act when the sliding door is opened from the fully closed state to the position of the non-operating distance D by simply adding the linking member and the operating pin. Can be prepared.

（３）の構成によれば、全閉状態から非作動距離Ｄの位置までを除き、該連係部材を介して常に一定の閉止力を引戸に伝達することができる。 According to the configuration of (3), a constant closing force can always be transmitted to the sliding door through the linking member except from the fully closed state to the position of the non-operating distance D.

（４）の構成によれば、遅延機構を構成する連係部材を配置するための特別な空間は不要であり、引戸には上端に作動ピンを固定するだけで良く、既存の引戸の開閉装置に最小限の設計変更を行うだけで容易に組み込むことができる。 According to the configuration of (4), no special space is required for arranging the linking members constituting the delay mechanism, and the sliding door only needs to be fixed with an operating pin at the upper end, and the existing sliding door opening / closing device can be used. It can be easily incorporated with minimal design changes.

次に、添付図面に示した実施形態に基づき、本発明を更に詳細に説明する。図１は本発明に係る引戸の開閉装置を組み込んだ引戸設備を示し、図２〜図４は基本構造の詳細を示し、図５〜図１１は本発明の引戸の開閉装置の詳細を示し、図中符号１は引戸、２は引戸枠、３は戸袋パネル、４は欄間パネル、５は壁面パネルをそれぞれ示している。 Next, the present invention will be described in more detail based on the embodiments shown in the accompanying drawings. FIG. 1 shows a sliding door facility incorporating a sliding door opening / closing device according to the present invention, FIGS. 2 to 4 show details of a basic structure, and FIGS. 5 to 11 show details of a sliding door opening / closing device of the present invention. In the figure, reference numeral 1 is a sliding door, 2 is a sliding door frame, 3 is a door pocket panel, 4 is a column panel, and 5 is a wall panel.

本実施形態では、前記引戸１と戸袋パネル３は、透光性のガラス板を枠体で保持した構造となっており、前記戸袋パネル３は引戸枠２に移動不能に保持され、前記引戸１が前記戸袋パネル３と重なるように横方向へスライド開閉するようになって、いわゆる片開き方式のものである。勿論、前記戸袋パネル３の代わりに、二枚目の引戸を設け、両引戸を互いに引き違い可能に設けた両開き方式であっても構わない。 In the present embodiment, the sliding door 1 and the door pocket panel 3 have a structure in which a translucent glass plate is held by a frame body, and the door pocket panel 3 is held immovably by the sliding door frame 2 and the sliding door 1 is held. Is slid open and closed in the lateral direction so as to overlap the door pocket panel 3, and is a so-called one-sided opening method. Of course, instead of the door pocket panel 3, a second sliding door may be provided, and both sliding doors may be provided so as to be able to slide from each other.

前記引戸枠２は、門型であり、戸先側枠６と戸尻側枠７の上端間に上枠８を渡設した構造であり、該上枠８の下方開放した空間９内にレール１０を内蔵している。前記レール１０は、下面の中央部に開口溝を備えた断面略Ｃ字形の長尺部材であり、戸先側の端部を除き前記上枠８の略全長に設けている。 The sliding door frame 2 is a gate type and has a structure in which an upper frame 8 is laid between the upper ends of the door end side frame 6 and the door tail side frame 7, and a rail is provided in a space 9 which is open downward of the upper frame 8. 10 is built-in. The rail 10 is a long member having a substantially C-shaped cross section having an opening groove in the central portion of the lower surface, and is provided over the substantially entire length of the upper frame 8 except for the end portion on the door end side.

そして、前記引戸１は、戸先側の縦枠１１と戸尻側の縦枠１２の上下端間に上部枠１３と下部枠１４とを連結して構成した枠体間にガラス板１５を保持した構造であり、戸先側の縦枠１１には表裏両側に把手１６，１６を設けている。本実施形態の引戸１は、ガラス引戸であり、重量があるため通常の引戸よりも自閉のために大きな閉止力を必要とするので、初期開力を小さくすることは使用勝手において重要である。 The sliding door 1 holds a glass plate 15 between the upper and lower ends of the vertical frame 11 on the door end side and the vertical frame 12 on the door end side, and the upper frame 13 and the lower frame 14 are connected to each other. The vertical frame 11 on the door end side is provided with handles 16 and 16 on both the front and back sides. Since the sliding door 1 of the present embodiment is a glass sliding door and is heavy, it requires a larger closing force for self-closing than a normal sliding door. Therefore, it is important for usability to reduce the initial opening force. ..

前記引戸枠２は、床面Ｆから天井Ｓに立設した支柱１７，１７に、前記戸先側枠６と戸尻側枠７を嵌合するとともに、ネジ止め固定し、天井Ｓと上枠８との間に前記欄間パネル４を装着し、更に前記支柱１７，１７を介して前記壁面パネル５，５をそれぞれ連結している。ここで、前記欄間パネル４及び壁面パネル５は、通常の間仕切パネルを用いているので、詳細は省略する。 In the sliding door frame 2, the door tip side frame 6 and the door tail side frame 7 are fitted to the columns 17 and 17 erected from the floor surface F to the ceiling S, and fixed by screws, and the ceiling S and the upper frame are fixed. The inter-column panel 4 is mounted between the column 8 and the wall panels 5 and 5, respectively, via the columns 17 and 17. Here, since the normal partition panel is used for the inter-column panel 4 and the wall surface panel 5, the details will be omitted.

そして、前記引戸１の上部枠１３の上端の戸先側と戸尻側に設けた吊車１８，１８を、前記レール１０に走行可能に支持するとともに、該引戸１の下部枠１４の下面側に沿って設けた凹溝１９内に、全閉状態の引戸１の戸尻側に対応する床面Ｆに突設した垂直回転軸を有するガイドローラ２０を受け入れて、吊り下げ状態の引戸１の下部を安定に開閉案内している。 Then, the suspension wheels 18 and 18 provided on the door tip side and the door tail side of the upper end of the upper frame 13 of the sliding door 1 are supported on the rail 10 so as to be travelable, and on the lower surface side of the lower frame 14 of the sliding door 1. A guide roller 20 having a vertical rotation axis protruding from the floor surface F corresponding to the door tail side of the sliding door 1 in the fully closed state is received in the concave groove 19 provided along the groove, and the lower portion of the sliding door 1 in the suspended state is received. Is stably guided to open and close.

前記戸袋パネル３は、ガラス板２１の一側縁部を前記戸尻側枠７に保持するとともに、上縁部を前記上枠８に保持し、更にガラス板２１の下縁部を床面Ｆに敷設した地レール部材２２で支持するとともに、他側縁部を縦枠部材２３で支持し、該縦枠部材２３は前記床面Ｆと前記上枠８間に立設し、上下端部を上枠８と地レール部材２２に連結している。 In the door pocket panel 3, one side edge portion of the glass plate 21 is held by the door tail side frame 7, the upper edge portion is held by the upper frame 8, and the lower edge portion of the glass plate 21 is held by the floor surface F. The other side edge portion is supported by the vertical frame member 23, and the vertical frame member 23 is erected between the floor surface F and the upper frame 8, and the upper and lower end portions are supported by the ground rail member 22 laid in the floor. It is connected to the upper frame 8 and the ground rail member 22.

また、前記引戸１の戸先側の縦枠１１の端部には弾性材料からなる戸当り部材２４を設けるとともに、前記戸先側枠６の側面に前記戸当り部材２４を受け入れて気密性を高める接合溝２５を形成し、更に前記引戸１が全開状態において前記戸尻側の縦枠１２を当止するクッション部材２６を前記戸尻側枠７の側面に取付けている。 Further, a door stop member 24 made of an elastic material is provided at the end of the vertical frame 11 on the door end side of the sliding door 1, and the door stop member 24 is received on the side surface of the door end side frame 6 to provide airtightness. A cushion member 26 for forming a joint groove 25 to be raised and further stopping the vertical frame 12 on the door tail side when the sliding door 1 is fully opened is attached to the side surface of the door tail side frame 7.

本発明に係る引戸の開閉装置は、図５〜図１１に示すように、閉止方向へ閉止力を引戸１に付与する自閉装置Ａと、全閉状態から作動距離Ｌの位置まで引戸１を開く際に閉止方向への弾性力を蓄積し、開状態から閉止方向へ移動してきた引戸１を作動距離Ｌの位置から全閉状態まで蓄積弾性力によって閉止動作を支援する引き込み装置Ｂとを備えた引戸の開閉装置であって、前記自閉装置Ａと引戸１の間に、全閉状態から非作動距離Ｄの位置まで引戸１を開く際に該自閉装置Ａによる閉止力が作用しないように遅延機構Ｃを設けるとともに、作動距離Ｌより非作動距離Ｄを短く設定したことを特徴とする。 As shown in FIGS. 5 to 11, the sliding door opening / closing device according to the present invention includes a self-closing device A that applies a closing force to the sliding door 1 in the closing direction, and the sliding door 1 from a fully closed state to a position of an operating distance L. It is provided with a retracting device B that accumulates elastic force in the closing direction when opening and supports the closing operation of the sliding door 1 that has moved from the open state to the closing direction from the position of the operating distance L to the fully closed state by the accumulated elastic force. In the sliding door opening / closing device, the closing force of the self-closing device A does not act when the sliding door 1 is opened from the fully closed state to the position of the non-operating distance D between the self-closing device A and the sliding door 1. The delay mechanism C is provided in the vehicle, and the non-operating distance D is set shorter than the operating distance L.

具体的には、前記遅延機構Ｃは、図５及び図１１に示すように、引戸１の移動方向に向けて連係部材２７を配置し、該連係部材２７に引戸１の移動方向に延びたガイド溝２８を形成し、引戸１に固定した作動ピン２９を前記ガイド溝２８内で前記非作動距離Ｄだけ相対的にスライド移動可能とし、前記自閉装置Ａの作動部３０に前記連係部材２７を連結して、該連係部材２７を介して閉止力を引戸１に伝達する構造であり、全閉状態で前記作動ピン２９を前記ガイド溝２８内の戸先側端に位置させている。前記作動ピン２９が、前記ガイド溝２８内の戸先側端から戸尻側端まで移動する距離が前記非作動距離Ｄである。 Specifically, as shown in FIGS. 5 and 11, the delay mechanism C arranges the linking member 27 in the moving direction of the sliding door 1, and guides the linking member 27 extending in the moving direction of the sliding door 1. A groove 28 is formed so that the operating pin 29 fixed to the sliding door 1 can be relatively slidably moved in the guide groove 28 by the non-operating distance D, and the linking member 27 is attached to the operating portion 30 of the self-closing device A. The structure is such that the closing force is transmitted to the sliding door 1 via the linking member 27, and the operating pin 29 is positioned at the door end side end in the guide groove 28 in the fully closed state. The non-operating distance D is the distance at which the operating pin 29 moves from the door end side end to the door tail side end in the guide groove 28.

更に詳しくは、前記連係部材２７は、図７に示すように、戸先側を除く本体部が側面開放した断面略コ字形の長尺部材であり、下面板３１に長手方向に沿って二対の長孔３２，３２を形成し、該長孔３２に前記ガイド溝２８を形成したスライド部材３３をそれぞれ嵌合状態でネジ止めして固定し、戸先側の端部には前記自閉装置Ａの作動部３０を連結するための連結孔３４を形成し、前記引戸１の上部枠１３の上面に沿って開閉方向に向けて配置する。一方、前記引戸１の上部枠１３の上面で、戸先側と戸尻側には、前記吊車１８を取付けるための取付台座３５をそれぞれネジ止め固定し、両取付台座３５，３５の間であって、前記ガイド溝２８，２８に対応させて前記作動ピン２９を上方へ向けて突設している。前記作動ピン２９は、前記スライド部材３３のガイド溝２８に挿通する軸部３６Ａと該ガイド溝２８の上縁に係止するフランジ部３６Ｂを有するブッシュ３６を取付ネジ３７で前記引戸１の上部枠１３の上面に螺合して取付けている。前記遅延機構Ｃを構成する連係部材２７は、前記引戸１の上端と前記レール１０の間に配置するが、前記引戸１の上部枠１３の上部は、前記引戸枠２の上枠８の空間９内に位置するので、前記連係部材２７は直視できない位置にある。 More specifically, as shown in FIG. 7, the linking member 27 is a long member having a substantially U-shaped cross section in which the main body portion excluding the door end side is open on the side surface, and two pairs are formed on the lower surface plate 31 along the longitudinal direction. The elongated holes 32 and 32 are formed, and the slide members 33 having the guide grooves 28 formed in the elongated holes 32 are screwed and fixed in the fitted state, respectively, and the self-closing device is attached to the end on the door end side. A connecting hole 34 for connecting the operating portion 30 of A is formed, and is arranged in the opening / closing direction along the upper surface of the upper frame 13 of the sliding door 1. On the other hand, on the upper surface of the upper frame 13 of the sliding door 1, the mounting pedestals 35 for mounting the suspension wheel 18 are fixed by screws on the door tip side and the door tail side, respectively, and are between the two mounting pedestals 35 and 35. Therefore, the operating pin 29 is projected upward so as to correspond to the guide grooves 28 and 28. The actuating pin 29 has a bush 36 having a shaft portion 36A inserted into the guide groove 28 of the slide member 33 and a flange portion 36B locked to the upper edge of the guide groove 28 with mounting screws 37 to form an upper frame of the sliding door 1. It is screwed and attached to the upper surface of 13. The linking member 27 constituting the delay mechanism C is arranged between the upper end of the sliding door 1 and the rail 10, and the upper part of the upper frame 13 of the sliding door 1 is the space 9 of the upper frame 8 of the sliding door frame 2. Since it is located inside, the linking member 27 is in a position that cannot be directly viewed.

ここで、前記自閉装置Ａは、引戸枠２に定荷重巻きバネ３８を固定し、該定荷重巻きバネ３８から引き出したワイヤー３９からなる前記作動部３０の端部を前記連係部材２７の連結孔３４に連結し、全閉状態から非作動距離Ｄの位置までを除き、該連係部材２７を介して常に一定の閉止力を引戸１に伝達する構造である。前記定荷重巻きバネ３８は、常に一定の荷重で前記ワイヤー３９を巻き込む公知の構造のものであるので、詳細な説明は省略する。前記定荷重巻きバネ３８は、前記レール１０の存在しない前記上枠８の空間９内に固定している。前記引戸１を開き始めて非作動距離Ｄの区間では、前記作動ピン２９が、前記スライド部材３３のガイド溝２８の戸先端部から戸尻端部まで移動し、負荷は全くかからない。そして、前記作動ピン２９が、前記スライド部材３３のガイド溝２８の戸尻端部に達した後は、該作動ピン２９とスライド部材３３が、一体となって開閉方向に移動し、前記定荷重巻きバネ３８からワイヤー３９を一定荷重の負荷のもと引き出すことになる。逆に、前記引戸１を閉止方向へ移動する際には、前記定荷重巻きバネ３８の一定荷重の引き込み力が前記ワイヤー３９とスライド部材３３及び作動ピン２９を介して引戸１に伝達し、前記ワイヤー３９が前記定荷重巻きバネ３８に引き込まれてしまうまで引戸１を閉止方向へ移動させる。尚、前記定荷重巻きバネ３８による閉止力が発生しなくなった状態は、前記引戸１が非作動距離Ｄだけ未だ開いた状態である。尚、本発明は、前記定荷重巻きバネ３８の代わりに、通常の巻きバネを用いることも可能である。その際に、定荷重巻きバネ３８又は通常の巻きバネは、負荷の強さを調整できるものを採用することが好ましい。 Here, in the self-closing device A, the constant load winding spring 38 is fixed to the sliding door frame 2, and the end portion of the operating portion 30 made of the wire 39 drawn from the constant load winding spring 38 is connected to the linking member 27. It is a structure that is connected to the hole 34 and always transmits a constant closing force to the sliding door 1 through the linking member 27 except from the fully closed state to the position of the non-operating distance D. Since the constant load winding spring 38 has a known structure in which the wire 39 is always wound with a constant load, detailed description thereof will be omitted. The constant load winding spring 38 is fixed in the space 9 of the upper frame 8 in which the rail 10 does not exist. In the section where the sliding door 1 is started to be opened and the non-operating distance D is set, the operating pin 29 moves from the door tip portion to the door tail end portion of the guide groove 28 of the slide member 33, and no load is applied. Then, after the actuating pin 29 reaches the door tail end of the guide groove 28 of the slide member 33, the actuating pin 29 and the slide member 33 move integrally in the opening / closing direction, and the constant load is applied. The wire 39 is pulled out from the winding spring 38 under a constant load. On the contrary, when the sliding door 1 is moved in the closing direction, the pulling force of a constant load of the constant load winding spring 38 is transmitted to the sliding door 1 via the wire 39, the slide member 33 and the operating pin 29, and the sliding door 1 is described. The sliding door 1 is moved in the closing direction until the wire 39 is pulled into the constant load winding spring 38. The state in which the closing force by the constant load winding spring 38 is no longer generated is a state in which the sliding door 1 is still open by the non-operating distance D. In the present invention, it is also possible to use a normal winding spring instead of the constant load winding spring 38. At that time, it is preferable to adopt a constant load winding spring 38 or a normal winding spring whose load strength can be adjusted.

前記引き込み装置Ｂは、前述のように、全閉状態から作動距離Ｌの位置まで引戸１を開く際に閉止方向への弾性力を蓄積し、開状態から閉止方向へ移動してきた引戸１を作動距離Ｌの位置から全閉状態まで蓄積弾性力によって閉止動作を支援する公知の構造であり、
前記レール１０の溝内に配置する。通常、戸先側の前記吊車１８は、前記引き込み装置Ｂと一体化されており、該吊車１８の本体部から戸尻側へ延びた杆体４０の内部に組み込まれており、該杆体４０の戸尻端に設けた転動車４１が前記レール１０内を移動して姿勢を保つようになっている。 As described above, the retracting device B accumulates elastic force in the closing direction when opening the sliding door 1 from the fully closed state to the position of the operating distance L, and operates the sliding door 1 that has moved from the open state to the closing direction. It is a known structure that supports the closing operation by the accumulated elastic force from the position of the distance L to the fully closed state.
It is arranged in the groove of the rail 10. Normally, the suspension wheel 18 on the door end side is integrated with the pull-in device B, and is incorporated inside a rod 40 extending from the main body of the suspension wheel 18 to the door tail side, and the door of the rod 40 The rolling wheel 41 provided at the tail end moves in the rail 10 and maintains its posture.

ここで、前記作動距離Ｌは、前記レール１０内に固定したトリガー４２の位置で決定される。全閉状態から引戸１を開いていくと、該トリガー４２に係止した前記引き込み装置Ｂの作動部が変位し、該引き込み装置Ｂの引張りコイルばねを引き伸ばして弾性力を蓄積し、前記トリガー４２に対して所定距離（作動距離Ｌ）だけ移動した後、前記作動部がトリガー４２から外れて杆体４０の適所に係止し、引張りコイルばねに弾性力を蓄積した状態を維持して引戸１が開放される。そして、前記引戸１を閉じる際には、引戸１が閉止方向へ移動して、前記トリガー４２の位置に作動部が来ると、該作動部は杆体４０から外れると同時に前記トリガー４２に係止し、前記引張りコイルばねの蓄積弾性力をトリガー４２に支点として開放し、引戸１を全閉状態まで閉止動作を支援する。 Here, the working distance L is determined by the position of the trigger 42 fixed in the rail 10. When the sliding door 1 is opened from the fully closed state, the operating portion of the pulling device B locked to the trigger 42 is displaced, the tension coil spring of the pulling device B is stretched to accumulate elastic force, and the trigger 42 is accumulated. After moving a predetermined distance (operating distance L) with respect to the above, the operating portion is disengaged from the trigger 42 and locked in an appropriate position of the rod 40, and the sliding door 1 maintains a state in which elastic force is accumulated in the tension coil spring. It will be released. Then, when the sliding door 1 is closed, when the sliding door 1 moves in the closing direction and the operating portion comes to the position of the trigger 42, the operating portion is disengaged from the rod 40 and at the same time locked to the trigger 42. The accumulated elastic force of the tension coil spring is opened to the trigger 42 as a fulcrum to support the closing operation of the sliding door 1 until it is fully closed.

引戸１の閉止支援という意味では、前記自閉装置Ａと引き込み装置Ｂは、負荷が切れ目無く引戸１に作用する必要がある。そのため、前記作動距離Ｌより非作動距離Ｄを短く設定し、前記自閉装置Ａと引き込み装置Ｂの負荷が重なる区間を設けた。しかし、併用区間は、出来るだけ短い方が初期開力を小さくする上で有利である。そのため、本実施形態では、前記作動距離Ｌを１１７ｍｍ、前記非作動距離Ｄを１１０ｍｍと設定したが、誤差を考慮して実用的には、[作動距離Ｌ]−[非作動距離Ｄ]≦１０ｍｍとなるように設定することが好ましい。 In the sense of supporting the closing of the sliding door 1, the self-closing device A and the pull-in device B need to have a load acting on the sliding door 1 seamlessly. Therefore, the non-operating distance D is set shorter than the operating distance L, and a section where the loads of the self-closing device A and the pulling device B overlap is provided. However, it is advantageous to make the combined section as short as possible in order to reduce the initial opening force. Therefore, in the present embodiment, the working distance L is set to 117 mm and the non-working distance D is set to 110 mm, but in consideration of an error, practically, [working distance L]-[non-working distance D] ≤ 10 mm. It is preferable to set so as to be.

前記引戸１の開閉動作時における前記自閉装置Ａと引き込み装置Ｂ及び遅延機構Ｃの作用について、図５〜図１０に基づいて簡単に説明する。先ず、全閉状態から引戸１を開く際に、引き込み装置Ｂに閉止方向への弾性力を蓄積するが、引戸１は非作動距離Ｄの区間では自閉装置Ａの負荷のかかり始めを遅延機構Ｃによって遅らせることができるので、この非作動距離Ｄだけ開く間にある程度加速が付く。引戸１の慣性力を利用することで引き込み装置Ｂと自閉装置Ａの負荷が重なった開力の重い区間（非作動距離Ｄと作動距離Ｌの間の区間）を通過させることができ、その後は自閉装置Ａの負荷だけになるので、使用者の感覚として重く感じさせないようにすることができる。一方、全開状態若しくは途中の開状態から引戸１を閉じる際には、引戸１の把手１６から手を離せば、自閉装置Ａによる一定の閉止力によって引戸１は閉止方向へ自動的に移動するが、引き込み装置Ｂが作動した直後に自閉装置Ａの閉止力が作用しなくなるので、引き込み装置Ｂの蓄積弾性力だけでゆっくりと全閉状態まで閉じることができる。 The operations of the self-closing device A, the pull-in device B, and the delay mechanism C during the opening / closing operation of the sliding door 1 will be briefly described with reference to FIGS. 5 to 10. First, when the sliding door 1 is opened from the fully closed state, an elastic force in the closing direction is accumulated in the retracting device B, but the sliding door 1 delays the start of the load of the self-closing device A in the non-operating distance D section. Since it can be delayed by C, some acceleration is applied while the non-operating distance D is opened. By utilizing the inertial force of the sliding door 1, it is possible to pass a section with a heavy opening force (a section between the non-operating distance D and the operating distance L) in which the loads of the pulling device B and the self-closing device A overlap, and then the section is passed. Is only the load of the self-closing device A, so that the user does not feel heavy. On the other hand, when closing the sliding door 1 from the fully opened state or the halfway opened state, if the hand is released from the handle 16 of the sliding door 1, the sliding door 1 automatically moves in the closing direction due to a constant closing force by the self-closing device A. However, since the closing force of the self-closing device A does not act immediately after the pulling device B is activated, the retracting device B can slowly close to the fully closed state only by the accumulated elastic force.
