本発明における引き戸装置では、それぞれ独立した部品からなる第１フレーム１５および第２フレーム１６で振止め枠１４を構成し、各フレーム１５・１６の第１締結座２９と第２締結座３８に、仮組み時に互いに係合する第１係合体３０と第２係合体４０を設けた。こうした引き戸装置によれば、第１フレーム１５と第２フレーム１６とを連結することで、第１係合体３０と第２係合体４０を互いに係合させて、戸パネル３を仮組み状態に保持することができる。また、戸パネル３を仮組みしたのちの作業者は、戸パネル３から手を離して戸パネル３の垂直姿勢の確認作業や、ねじ体４４の締結作業を行うことができるので、従来の引き戸装置に比べて、戸パネル３の建込み作業を単独の作業者のみで安全に、しかもより少ない手間で確実に行うことができる。以上より、本発明によれば、施工性に優れた引き戸装置を提供できる。 In the sliding door device of the present invention, the steady rest frame 14 is composed of the first frame 15 and the second frame 16 each of which are independent parts, and the first fastening seat 29 and the second fastening seat 38 of each of the frames 15 and 16 are formed. A first engaging body 30 and a second engaging body 40 that engage with each other at the time of temporary assembly are provided. According to such a sliding door device, by connecting the first frame 15 and the second frame 16, the first engaging body 30 and the second engaging body 40 are engaged with each other, and the door panel 3 is held in the temporarily assembled state. can do. Further, since the worker after temporarily assembling the door panel 3 can take his / her hand away from the door panel 3 to check the vertical posture of the door panel 3 and to fasten the screw body 44, the conventional sliding door can be used. Compared to the device, the work of building the door panel 3 can be performed safely and surely with less labor by only a single operator. From the above, according to the present invention, it is possible to provide a sliding door device having excellent workability.

第１締結座２９の左右両側にパネル側爪部３１を備えた第１係合体３０を設け、第２締結座３８の左右両側に壁側爪部４１を備えた第２係合体４０を設けるようにした。こうした振止め構造４によれば、両締結座２９・３８を仮組みした状態において、パネル側爪部３１と壁側爪部４１が係合して、戸パネル３が壁面Ｗから離れる向きに傾くことを防止できる。また、各締結座２９・３８の左右両側に第１係合体３０と第２係合体４０が設けられているので、仮組み状態において第１締結座２９と第２締結座３８が左右にずれ動くことを第１係合体３０または第２係合体４０で規制して、ねじ体４４による両締結座２９・３８の締結をさらに的確に行うことができる。 A first engaging body 30 having panel-side claws 31 is provided on both left and right sides of the first fastening seat 29, and a second engaging body 40 having wall-side claws 41 is provided on both left and right sides of the second fastening seat 38. I made it. According to the anti-vibration structure 4, in a state where both fastening seats 29 and 38 are temporarily assembled, the panel side claw portion 31 and the wall side claw portion 41 are engaged with each other, and the door panel 3 is tilted in a direction away from the wall surface W. Can be prevented. Further, since the first engaging body 30 and the second engaging body 40 are provided on both the left and right sides of the fastening seats 29 and 38, the first fastening seat 29 and the second fastening seat 38 shift to the left and right in the temporarily assembled state. This can be regulated by the first engaging body 30 or the second engaging body 40, and both fastening seats 29 and 38 can be more accurately fastened by the screw body 44.

振止めベース１３と第２フレーム１６の間に、上下調整溝３９と調整ガイド軸３６を備えた上下位置調整構造を設けて、第２フレーム１６を振止めベース１３で上下スライド可能に案内支持するようにした。こうした振止め構造４によれば、下荷重型の戸パネル３を開閉するとき、第２フレーム１６が上下動することでガイドレール２の不陸を吸収することができるので、ランナー体６が下凹み状の不陸部分を通過するとき、脱輪することをよく防止できる。 A vertical position adjustment structure provided with a vertical adjustment groove 39 and an adjustment guide shaft 36 is provided between the steady rest base 13 and the second frame 16, and the second frame 16 is guided and supported by the steady rest base 13 so as to be slidable up and down. I did it. According to the anti-vibration structure 4, when the lower load type door panel 3 is opened and closed, the second frame 16 moves up and down to absorb the non-landing of the guide rail 2, so that the runner body 6 is lowered. It is possible to prevent the wheel from coming off when passing through a dented non-landing part.

第１係合体３０と第２係合体４０のいずれか一方に、仮組みガイド部３２が形成された振止め構造４によれば、戸パネル３を第２フレーム１６へ向かって押込み操作する際に、第２締結座３８を仮組みガイド部３２で上向きに移動させて、第１係合体３０が第２係合体４０の下面側を潜り抜けるのを補助できる。また、第１係合体３０が第２係合体４０の下面側を潜り抜けるのと同時に、第２フレーム１６が自重で落下して、第２締結座３８が第１締結座２９の上面で支持され、第２係合体４０が第１係合体３０の前側に落ち込んで仮組み状態を保持する。従って、第１係合体３０を第２係合体４０に係合させる手間を省いて、戸パネル３を第２フレーム１６へ向かって押込み操作するだけで、戸パネル３の仮組み作業を簡便に行える。 According to the anti-vibration structure 4 in which the temporary assembly guide portion 32 is formed on either the first engaging body 30 or the second engaging body 40, when the door panel 3 is pushed toward the second frame 16 The second fastening seat 38 can be moved upward by the temporary assembly guide portion 32 to assist the first engaging body 30 to slip through the lower surface side of the second engaging body 40. Further, at the same time that the first engaging body 30 slips through the lower surface side of the second engaging body 40, the second frame 16 falls by its own weight, and the second fastening seat 38 is supported by the upper surface of the first fastening seat 29. , The second engaging body 40 falls to the front side of the first engaging body 30 and holds the temporarily assembled state. Therefore, the temporary assembly work of the door panel 3 can be easily performed only by pushing the door panel 3 toward the second frame 16 without the trouble of engaging the first engaging body 30 with the second engaging body 40. ..

第１締結座２９にねじ込まれる複数のねじ体４４と、第２締結座３８に形成される複数のねじ挿通溝４５と、ねじ挿通溝４５の前端に形成されるねじ連結口４６で、締結構造１７を構成した。また、ねじ連結口４６は第２締結座３８の前縁で開口させるようにした。こうした振止め構造４によれば、第１フレーム１５と第２フレーム１６の左右方向の位置合わせを行うとき、ねじ体４４のねじ軸をねじ連結口４６に落込ませることにより、第１締結座２９と第２締結座３８を大まかに位置決めできる。また、大まかに位置決めされた状態で、戸パネル３を第２フレーム１６に向かって押し込み操作することで、ねじ体４４をねじ挿通溝４５に係合させて、両締結座２９・３８をより正確に位置決めし、同時に両締結座２９・３８が左右にずれ動くのを規制できる。従って、戸パネル３の仮組み作業をさらに的確に行える。また、ねじ体４４を第１締結座２９に上方からねじ込むので、ねじ体４４による両締結座２９・３８の締結作業を、振止め構造の上側の自由空間で確実にしかも簡便に行える。 A fastening structure consisting of a plurality of screw bodies 44 screwed into the first fastening seat 29, a plurality of screw insertion grooves 45 formed in the second fastening seat 38, and a screw connecting port 46 formed at the front end of the screw insertion groove 45. 17 was configured. Further, the screw connecting port 46 is opened at the leading edge of the second fastening seat 38. According to the anti-vibration structure 4, when the first frame 15 and the second frame 16 are aligned in the left-right direction, the screw shaft of the screw body 44 is dropped into the screw connecting port 46 to cause the first fastening seat 29. And the second fastening seat 38 can be roughly positioned. Further, by pushing the door panel 3 toward the second frame 16 in a roughly positioned state, the screw body 44 is engaged with the screw insertion groove 45, and both fastening seats 29 and 38 are more accurately positioned. It is possible to regulate the movement of both fastening seats 29 and 38 from side to side at the same time. Therefore, the temporary assembly work of the door panel 3 can be performed more accurately. Further, since the screw body 44 is screwed into the first fastening seat 29 from above, the fastening work of both fastening seats 29 and 38 by the screw body 44 can be reliably and easily performed in the free space above the vibration stop structure.

アシストユニット５Ａは、往復スライド自在なスライダー５０と、スライダー５０を移動付勢する蓄力ばね５１と、戸パネル３の移動動作を制動するダンパーユニット５２などを備えるようにした。また、ダンパーユニット５２は、一対のダンパー６４と、両ダンパー６４のシリンダー６９を支持するダンパーホルダー６５を備えるようにした。こうしたアシストユニット５Ａによれば、一対のダンパー６４におけるピストンロッド７０の出退ストロークを、制動ストロークの約半分程度に小さくすることができるので、その分だけダンパーユニット５２の左右長さを小さくしてアシストユニット５Ａをコンパクトに構成できる。従って、パネル幅が小さな戸パネル３であっても、アシストユニット５Ａを問題なく適用できる。 The assist unit 5A is provided with a slider 50 that can be slid back and forth, a storage spring 51 that moves and urges the slider 50, a damper unit 52 that brakes the moving operation of the door panel 3, and the like. Further, the damper unit 52 includes a pair of dampers 64 and a damper holder 65 that supports the cylinders 69 of both dampers 64. According to such an assist unit 5A, the retracting stroke of the piston rod 70 in the pair of dampers 64 can be reduced to about half of the braking stroke, so that the left-right length of the damper unit 52 is reduced by that amount. The assist unit 5A can be compactly configured. Therefore, even if the door panel 3 has a small panel width, the assist unit 5A can be applied without any problem.

蓄力ばね５１はアシストケース４９の一側壁と、同壁から最も離れたスライダー５０の側端に掛止して、その中途部がスライダー５０に形成したばね溝５７に収容されるようにした。こうしたアシストユニット５Ａによれば、スライダー５０のスライドスペースを利用して、蓄力ばね５１をスライダー５０と平行に配置できるので、蓄力ばね５１の配置スペースが別途確保されている場合に比べて、アシストユニット５Ａを小形化しコンパクト化できる。 The storage spring 51 is hooked on one side wall of the assist case 49 and the side end of the slider 50 farthest from the wall, and the middle portion thereof is accommodated in the spring groove 57 formed in the slider 50. According to such an assist unit 5A, the storage spring 51 can be arranged in parallel with the slider 50 by using the slide space of the slider 50, so that the arrangement space of the storage spring 51 can be arranged in parallel with the slider 50. The assist unit 5A can be made smaller and more compact.

アシストユニット５Ａは、先の部材以外に、スライダー５０で揺動可能に、かつ同行移動可能に支持される切換えレバー７３と、同レバー７３を蓄力保持姿勢と蓄力開放姿勢に切換え操作するガイド体１２の切換え部２４を備えるようにした。また、切換えレバー７３には、切換え部２４が係脱する受動凹部７４と、ロック開口７９に係脱するロック爪７６を形成した。こうしたアシストユニット５Ａによれば、切換えレバー７３が切換え部２４で蓄力保持姿勢に切換え操作された状態では、ロック爪７６がロック開口７９と係合してスライダー５０の移動を阻止し、蓄力ばね５１を最大伸張姿勢に保持する。また、切換えレバー７３が切換え部２４で蓄力開放姿勢に切換え操作された状態では、ロック爪７６がロック開口７９から離脱してスライダー５０の移動を許し、蓄力ばね５１がスライダー５０を引寄せ操作する。このようにアシストユニット５Ａを備えた引き戸装置によれば、開閉ストロークの端部寄りからストローク端まで、戸パネル３にダンパー６４の制動力を作用させながら、蓄力ばね５１の付勢力でゆっくりと移動させることができる。 In addition to the above member, the assist unit 5A has a switching lever 73 that is supported by a slider 50 so as to be swingable and accompany movement, and a guide that switches the lever 73 between a storage holding posture and a storage opening posture. A switching unit 24 of the body 12 is provided. Further, the switching lever 73 is formed with a passive recess 74 in which the switching portion 24 engages and disengages, and a lock claw 76 in which the lock opening 79 engages and disengages. According to the assist unit 5A, when the switching lever 73 is switched to the storage capacity holding posture by the switching unit 24, the lock claw 76 engages with the lock opening 79 to prevent the slider 50 from moving, and the storage capacity is stored. The spring 51 is held in the maximum extended posture. Further, in the state where the switching lever 73 is switched to the storage capacity opening posture by the switching unit 24, the lock claw 76 is separated from the lock opening 79 to allow the slider 50 to move, and the storage capacity spring 51 attracts the slider 50. Manipulate. As described above, according to the sliding door device provided with the assist unit 5A, the braking force of the damper 64 is applied to the door panel 3 from the end of the opening / closing stroke to the end of the stroke, and the urging force of the storage spring 51 is slowly applied.

First, the door roller 6 is assembled on the door panel 3, and the pair of assist units 5A and 5B and the slide rail 11 are assembled on the mounting portion 10. Further, with the bolt 44 screwed into the first fastening seat 29, the guide body 12 integrated with the first frame 15 is assembled to the rail wall 22 of the slide rail 11. At this time, a space larger than the thickness of the second fastening seat 38 is secured between the operating head of the bolt 44 and the first fastening seat 29. The guide rail 2 is fixed at a predetermined position on the floor surface, and the anti-vibration base 13 integrated with the second frame 16 is fixed at a predetermined position on the wall surface W with a screw 35. Next, as shown in FIG. 9, the door panel 3 is erected with the door roller 6 dropped onto the guide rail 2, and the door panel 3 is moved to a position where the first frame 15 faces the second frame 16.

上記の状態で戸パネル３を第２フレーム１６に向かって押し込み操作すると、図１０（ａ）に示すように、第１係合体３０の仮組みガイド部３２が第２係合体４０の前縁の下面に接当するため、第２フレーム１６は調整ガイド軸３６に案内されて徐々に上向きに押上げられて、第１係合体３０が第２係合体４０の下面側を潜り抜けるのを補助する。戸パネル３をさらに接近させて、第１係合体３０が第２係合体４０の下面側を潜り抜けたら、第２フレーム１６が自重で落下して、図１０（ｂ）に示すように第２締結座３８が第１締結座２９の上面で支持され、同時に第２係合体４０が第１係合体３０の前側に落ち込んで仮組み状態を保持する。従って、戸パネル３を第２フレーム１６へ向かって押込み操作するだけで、戸パネル３の仮組み作業を簡便に行って、第１係合体３０を第２係合体４０に係合させる手間を省くことができる。 When the door panel 3 is pushed toward the second frame 16 in the above state, the temporary assembly guide portion 32 of the first engaging body 30 becomes the leading edge of the second engaging body 40 as shown in FIG. 10A. In order to contact the lower surface, the second frame 16 is guided by the adjustment guide shaft 36 and gradually pushed upward to assist the first engaging body 30 to slip through the lower surface side of the second engaging body 40. .. When the door panel 3 is brought closer and the first engaging body 30 slips through the lower surface side of the second engaging body 40, the second frame 16 falls by its own weight and is second as shown in FIG. 10 (b). The fastening seat 38 is supported on the upper surface of the first fastening seat 29, and at the same time, the second engaging body 40 falls to the front side of the first engaging body 30 to maintain the temporarily assembled state. Therefore, by simply pushing the door panel 3 toward the second frame 16, the temporary assembly work of the door panel 3 can be easily performed, and the trouble of engaging the first engaging body 30 with the second engaging body 40 can be saved. be able to.

また、パネル側爪部３１の上端が第２係合体４０の下面を潜り抜ける間に、戸パネル３を左右に調整移動することにより、ボルト４４のねじ軸がねじ連結口４６に落ち込み係合するので、以後は戸パネル３を押込み操作することで、ボルト４４のねじ軸をねじ挿通溝４５に係合させて、仮組み状態に保持できる。最後に、パネル上部を前後に調整移動したのち、図１に示すように戸パネル３が垂直姿勢になった状態でボルト４４を締込んで、第２締結座３８と第１締結座２９を固定する。このとき、ボルト４４が第１締結座２９に上方からねじ込んであるので、ボルト４４による両締結座２９・３８の締結作業を、振止め構造の上側の自由空間で確実にしかも簡便に行える。 Further, while the upper end of the panel side claw portion 31 passes through the lower surface of the second engaging body 40, the door panel 3 is adjusted and moved to the left and right, so that the screw shaft of the bolt 44 falls into the screw connecting port 46 and engages. Therefore, after that, by pushing the door panel 3 in, the screw shaft of the bolt 44 can be engaged with the screw insertion groove 45 and held in the temporarily assembled state. Finally, after adjusting and moving the upper part of the panel back and forth, the bolt 44 is tightened in the state where the door panel 3 is in the vertical posture as shown in FIG. 1, and the second fastening seat 38 and the first fastening seat 29 are fixed. do. At this time, since the bolt 44 is screwed into the first fastening seat 29 from above, the fastening work of both fastening seats 29 and 38 by the bolt 44 can be performed reliably and easily in the free space above the vibration stop structure.

上記のように実施例１の引き戸装置によれば、第１フレーム１５と第２フレーム１６の位置合わせを行い、さらにボルト４４のねじ軸がねじ連結口４６に接当する状態で、戸パネル３を第２フレーム１６へ向かって押込み操作することにより、第１係合体３０と第２係合体４０を互いに係合させて、戸パネル３を仮組み状態に保持することができる。従って、従来の引き戸装置に比べて、戸パネル３の建込み作業を単独の作業者のみで安全に行える。また、戸パネル３を仮組みしたのちの作業者は、戸パネル３を起立状態のままで支持し続ける必要がない。そのため、戸パネル３から手を離して、ボルト４４を締込むために脚立を準備し、あるいは戸パネル３の垂直姿勢の確認作業や、ボルト４４の締結作業を行うなど、戸パネル３の建込み作業をより少ない手間で確実に行うことができ、全体として施工性に優れた引き戸装置を提供できる。 According to the sliding door device of the first embodiment as described above, the door panel 3 is aligned with the first frame 15 and the second frame 16 and the screw shaft of the bolt 44 is in contact with the screw connecting port 46. By pushing the screw toward the second frame 16, the first engaging body 30 and the second engaging body 40 can be engaged with each other, and the door panel 3 can be held in the temporarily assembled state. Therefore, as compared with the conventional sliding door device, the building work of the door panel 3 can be safely performed by only one operator. Further, the worker after temporarily assembling the door panel 3 does not need to continue to support the door panel 3 in an upright position. Therefore, the door panel 3 is built by taking the hand off the door panel 3 and preparing a stepladder to tighten the bolt 44, checking the vertical posture of the door panel 3, and fastening the bolt 44. It is possible to reliably perform the work with less labor, and it is possible to provide a sliding door device having excellent workability as a whole.

次に、戸パネル３が開閉されるときのアシストユニット５Ａ・５Ｂの作動状況を説明する。戸パネル３が全開放された状態では、アシストユニット５Ａの切換えレバー７３は蓄力保持姿勢に切換っており、蓄力ばね５１は図１１（ａ）に示すように最大伸張姿勢に保持されている。また、アシストユニット５Ｂの切換えレバー７３は蓄力開放姿勢に切換っており、蓄力ばね５１は最小収縮姿勢に保持されている。この状態から戸パネル３が閉じ操作されて閉じ端寄りまで接近すると、切換えレバー７３の受動凹部７４がガイド体１２の切換え部２４に接当するため、切換えレバー７３は図１１（ｂ）に示すように時計回転方向へ揺動操作され、図１１（ｃ）に示すように、そのロック爪７６がロック開口７９から離脱して、角部７７が切換え部２４で受止められる。 Next, the operating state of the assist units 5A and 5B when the door panel 3 is opened and closed will be described. When the door panel 3 is fully opened, the switching lever 73 of the assist unit 5A is switched to the storage capacity holding posture, and the storage capacity spring 51 is held in the maximum extension posture as shown in FIG. 11A. There is. Further, the switching lever 73 of the assist unit 5B is switched to the storage power opening posture, and the power storage spring 51 is held in the minimum contraction posture. When the door panel 3 is closed from this state and approaches the closed end, the passive recess 74 of the switching lever 73 comes into contact with the switching portion 24 of the guide body 12, so that the switching lever 73 is shown in FIG. 11 (b). As shown in FIG. 11 (c), the lock claw 76 is separated from the lock opening 79, and the corner portion 77 is received by the switching portion 24.

上記の状態のスライダー５０は、蓄力ばね５１のばね力を受けてケース本体５３の右側壁へ向かってスライド移動する。また、スライダー５０が移動するのに伴って、図７において下側のダンパー６４のピストンロッド７０がシリンダー６９内へ押込まれて、ダンパー６４から制動力を受ける。スライダー５０がさらにスライドして連結部６０がダンパーホルダー６５に接当すると、ダンパーユニット５２がスライダー５０に同行して移動する。その結果、図７において上側のダンパー６４のピストンロッド７０がシリンダー６９内へ押込まれて、ダンパー６４から制動力を受ける。図１１（ｄ）に示すように、戸パネル３が閉じ端まで移動したときの蓄力ばね５１は最小収縮姿勢に切換わる。このように、一対のダンパー６４は順に制動力を発揮して戸パネル３を連続して制動する。 The slider 50 in the above state receives the spring force of the storage spring 51 and slides toward the right wall of the case body 53. Further, as the slider 50 moves, the piston rod 70 of the lower damper 64 in FIG. 7 is pushed into the cylinder 69 and receives a braking force from the damper 64. When the slider 50 further slides and the connecting portion 60 comes into contact with the damper holder 65, the damper unit 52 moves along with the slider 50. As a result, in FIG. 7, the piston rod 70 of the upper damper 64 is pushed into the cylinder 69 and receives a braking force from the damper 64. As shown in FIG. 11D, the storage spring 51 switches to the minimum contraction posture when the door panel 3 moves to the closed end. In this way, the pair of dampers 64 exert braking force in order to continuously brake the door panel 3.

戸パネル３が閉じ端から開放操作されると、図１２（ｂ）に示すように、切換えレバー７３の角部７７が切換え部２４で受止められた状態のままで、ケース本体５３が戸パネル３に同行して開放方向へ移動する。このときのスライダー５０は、切換えレバー７３と共に切換え部２４で移動不能に保持されているので、蓄力ばね５１はケース本体５３が移動する向きに引伸ばされながら徐々にばね力を蓄える。そして、蓄力ばね５１が最大伸張姿勢に近づくと、図１２（ｂ）に示すように、ケース本体５３のロック開口７９が切換えレバー７３のロック爪７６の下面に接近する。この状態の切換えレバー７３は、角部７７が切換え部２４で受止められているので、反時計回転方向へ揺動しようとする。そのため、図１２（ｃ）に示すように、ロック開口７９の右側縁がロック爪７６の下面を潜り抜けるのと同時に、ロック爪７６がロック開口７９に落込む向きに切換えレバー７３が揺動し、蓄力ばね５１が最大伸張姿勢に保持される。以後、スライダー５０はケース本体５３に同行して移動し、切換えレバー７３は切換え部２４の下面側を通り抜けて、切換え部２４から離れて行く。 When the door panel 3 is opened from the closed end, as shown in FIG. 12B, the corner portion 77 of the switching lever 73 remains received by the switching portion 24, and the case body 53 moves to the door panel. Accompany 3 and move in the open direction. Since the slider 50 at this time is held immovably by the switching portion 24 together with the switching lever 73, the storage force spring 51 gradually stores the spring force while being stretched in the direction in which the case body 53 moves. Then, when the storage spring 51 approaches the maximum extension posture, the lock opening 79 of the case body 53 approaches the lower surface of the lock claw 76 of the switching lever 73, as shown in FIG. 12 (b). Since the corner portion 77 of the switching lever 73 in this state is received by the switching portion 24, the switching lever 73 tends to swing in the counterclockwise rotation direction. Therefore, as shown in FIG. 12 (c), at the same time that the right edge of the lock opening 79 passes through the lower surface of the lock claw 76, the switching lever 73 swings in the direction in which the lock claw 76 falls into the lock opening 79. , The storage spring 51 is held in the maximum extension posture. After that, the slider 50 moves along with the case main body 53, and the switching lever 73 passes through the lower surface side of the switching unit 24 and moves away from the switching unit 24.

先に説明したように、一対のアシストユニット５Ａ・５Ｂは左右対称に配置してあり、前者ユニット５Ａが閉じ端側で作動するのに対し、後者ユニット５Ｂは開放端側で作動する点が異なる。以下では、アシストユニット５Ｂの作動状況の概略を説明する。戸パネル３が全開放された状態におけるアシストユニット５Ｂの切換えレバー７３は、蓄力開放姿勢に切換っており、蓄力ばね５１は最小収縮姿勢に保持されている。この状態から戸パネル３が閉じ操作される間に、アシストユニット５Ｂ側の切換えレバー７３の受動凹部７４がガイド体１２の切換え部２４で捕捉され、その状態のままでケース本体５３が戸パネル３に同行して閉じ方向へ移動する。このときのスライダー５０は、切換えレバー７３と共に切換え部２４で移動不能に保持されているので、蓄力ばね５１はケース本体５３が移動する閉じ方向に引伸ばされながら徐々にばね力を蓄える。そして、ロック爪７６がロック開口７９に落込むことにより、蓄力ばね５１が最大伸張姿勢に保持される。 As described above, the pair of assist units 5A and 5B are arranged symmetrically, and the former unit 5A operates on the closed end side, while the latter unit 5B operates on the open end side. .. Hereinafter, the outline of the operating status of the assist unit 5B will be described. The switching lever 73 of the assist unit 5B in the state where the door panel 3 is fully opened is switched to the storage opening posture, and the storage spring 51 is held in the minimum contraction posture. While the door panel 3 is closed from this state, the passive recess 74 of the switching lever 73 on the assist unit 5B side is captured by the switching portion 24 of the guide body 12, and the case body 53 is held in that state as the door panel 3. Accompany and move in the closing direction. Since the slider 50 at this time is held immovably by the switching portion 24 together with the switching lever 73, the storage force spring 51 gradually stores the spring force while being stretched in the closing direction in which the case body 53 moves. Then, when the lock claw 76 falls into the lock opening 79, the storage spring 51 is held in the maximum extension posture.

戸パネル３が開放端寄りまで開放移動すると、切換えレバー７３の受動凹部７４がガイド体１２の切換え部２４で捕捉され、切換えレバー７３が揺動して、そのロック爪７６がロック開口７９から離脱し、角部７７が切換え部２４で受止められる。この状態のスライダー５０は、蓄力ばね５１のばね力を受けてスライド移動する。また、スライダー５０が移動するのに伴って、ダンパー６４のピストンロッド７０がシリンダー６９内へ押込まれて、ダンパー６４から制動力を受ける。スライダー５０がさらにスライドして連結部６０がダンパーホルダー６５に接当すると、ダンパーユニット５２がスライダー５０に同行して移動する。その結果、上側のダンパー６４のピストンロッド７０がシリンダー６９内へ押込まれて、ダンパー６４から制動力を受ける。戸パネル３が開放端まで移動したときの蓄力ばね５１は最小収縮姿勢に切換わる。 When the door panel 3 is opened and moved toward the open end, the passive recess 74 of the switching lever 73 is captured by the switching portion 24 of the guide body 12, the switching lever 73 swings, and the lock claw 76 is released from the lock opening 79. Then, the corner portion 77 is received by the switching portion 24. The slider 50 in this state slides by receiving the spring force of the storage spring 51. Further, as the slider 50 moves, the piston rod 70 of the damper 64 is pushed into the cylinder 69 and receives braking force from the damper 64. When the slider 50 further slides and the connecting portion 60 comes into contact with the damper holder 65, the damper unit 52 moves along with the slider 50. As a result, the piston rod 70 of the upper damper 64 is pushed into the cylinder 69 and receives braking force from the damper 64. When the door panel 3 moves to the open end, the storage spring 51 switches to the minimum contraction posture.

以上のように、一対のアシストユニット５Ａ・５Ｂが戸パネル３に設けられている引き戸装置によれば、閉じ端寄り（あるいは開放端寄り）から閉じ位置（あるいは開放位置）まで、戸パネル３にダンパー６４の制動力を作用させながらゆっくりと移動させることができる。従って、使用者はロック爪７６がロック開口７９から離脱する位置まで戸パネル３を閉じ操作（あるいは開放操作）するだけでよく、以後は、アシストユニット５Ａ（あるいは５Ｂ）が戸パネル３を自動的に閉じ位置（あるいは開放位置）まで移動操作する。このように、一対のアシストユニット５Ａ・５Ｂを備えた引き戸装置によれば、ユーザーが戸パネル３を閉じ端や開放端まで開閉する手間を省いて、引き戸装置の使い勝手を向上できる。また、戸パネル３が勢いよく開閉される場合でも、戸パネル３に各アシストユニット５Ａ・５Ｂの制動力を作用させてゆっくりと移動できるので、閉じ位置（あるいは開放位置）において手指が開口枠１と戸パネル３の間に挟まれることを解消できる。さらに、一対のアシストユニット５Ａ・５Ｂの切換えレバー７３を１個の切換え部２４で切換え操作できるので、個々のアシストユニット５Ａ・５Ｂに対応して切換え部２４を２個所に設ける必要がなく、その分だけ戸パネル３のアシスト構造を簡素化して低コスト化できる。 As described above, according to the sliding door device in which the pair of assist units 5A and 5B are provided on the door panel 3, the door panel 3 is located from the closed end side (or the open end side) to the closed position (or the open position). It can be moved slowly while applying the braking force of the damper 64. Therefore, the user only has to close (or open) the door panel 3 until the lock claw 76 is released from the lock opening 79, and thereafter, the assist unit 5A (or 5B) automatically closes the door panel 3. Move to the closed position (or open position). As described above, according to the sliding door device provided with the pair of assist units 5A and 5B, the user can save the trouble of opening and closing the door panel 3 to the closed end and the open end, and the usability of the sliding door device can be improved. Further, even when the door panel 3 is opened and closed vigorously, the door panel 3 can be moved slowly by applying the braking force of each assist unit 5A / 5B to the door panel 3, so that the fingers can move slowly in the closed position (or open position). It is possible to eliminate the problem of being sandwiched between the door panel 3 and the door panel 3. Further, since the switching lever 73 of the pair of assist units 5A / 5B can be switched by one switching unit 24, it is not necessary to provide the switching units 24 at two places corresponding to the individual assist units 5A / 5B. The assist structure of the door panel 3 can be simplified and the cost can be reduced by the amount.

戸パネル３が閉じ位置まで移動した場合、あるいは戸パネル３が開放位置まで移動した場合の振止め構造４は、その前面が戸パネル３で完全に覆われている。そのため、とくにデザインや外観上の印象が重視される引き戸装置において、振止め構造４を好適に応用できる利点がある。また、振止め構造４は、開口枠１に隣接する状態で、戸パネル３の開閉ストロークの中央付近の１か所に配置してあればよいので、開放操作された戸パネル３が戸袋内に収容される引き戸装置の場合でも、必要に応じて振止め構造４の交換や補修を支障なく行うことができる。 The front surface of the anti-vibration structure 4 when the door panel 3 is moved to the closed position or the door panel 3 is moved to the open position is completely covered with the door panel 3. Therefore, there is an advantage that the anti-vibration structure 4 can be suitably applied to the sliding door device in which the impression of design and appearance is particularly important. Further, since the anti-vibration structure 4 may be arranged at one place near the center of the opening / closing stroke of the door panel 3 in a state adjacent to the opening frame 1, the door panel 3 opened is placed in the door pocket. Even in the case of the sliding door device to be accommodated, the vibration damping structure 4 can be replaced or repaired as necessary without any trouble.

上下に隣接する一対のダンパー６４と、両ダンパー６４を支持するダンパーホルダー６５でダンパーユニット５２を構成し、各ダンパー６４のピストンロッド７０をアシストケース４９の右側壁（他側端）と、スライダー５０の左端の連結部６０に連結するようにした。こうしたアシストユニット５Ａ・５Ｂによれば、各ダンパー６４におけるピストンロッド７０の出退ストロークを、制動ストロークの約半分程度に小さくすることができるので、その分だけダンパーユニット５２の左右長さを小さくしてアシストユニット５Ａ・５Ｂをコンパクトに構成できる。従って、パネル幅が小さな戸パネル３であっても、アシストユニット５Ａ・５Ｂを問題なく適用できる。アシストケース４９の内部の上側から順に、一対のダンパー６４と、スライダー５０および蓄力ばね５１と、切換えレバー７３を記載順に配置するようにした。こうしたアシストユニット５Ａ・５Ｂによれば、同ユニット５Ａ・５Ｂの前後厚みを小さくできるので、前後厚みが小さな戸パネル３であっても、アシストユニット５Ａ・５Ｂを支障なく組込むことができる。 The damper unit 52 is composed of a pair of vertically adjacent dampers 64 and a damper holder 65 that supports both dampers 64, and the piston rod 70 of each damper 64 is attached to the right side wall (other side end) of the assist case 49 and the slider 50. It is connected to the connecting portion 60 at the left end of the above. According to these assist units 5A and 5B, the moving / retracting stroke of the piston rod 70 in each damper 64 can be reduced to about half of the braking stroke, so that the left-right length of the damper unit 52 is reduced accordingly. The assist units 5A and 5B can be compactly configured. Therefore, even if the door panel 3 has a small panel width, the assist units 5A and 5B can be applied without any problem. The pair of dampers 64, the slider 50, the storage spring 51, and the switching lever 73 are arranged in the order described from the upper side inside the assist case 49. According to such assist units 5A / 5B, the front-rear thickness of the units 5A / 5B can be reduced, so that the assist units 5A / 5B can be incorporated without any trouble even in the door panel 3 having a small front-rear thickness.

（実施例２）図１３および図１４に、実施例２に係る本発明の引き戸装置を構成する振止め構造４を示す。この実施例２では、第２フレーム１６の第２係合体４０の前部分に逆ヘ字状の第２の仮組みガイド部８２を一体に形成し、さらにねじ挿通溝４５の前端にボルト４４の操作頭部の出入りを許す円形のねじ連結口４６を形成している。他は実施例１と同じであるので、同じ部材に同じ符号を付してその説明を省略する。以下の実施例においても同じとする。 (Example 2) FIGS. 13 and 14 show a vibration damping structure 4 constituting the sliding door device of the present invention according to the second embodiment. In the second embodiment, the second temporary assembly guide portion 82 having an inverted C shape is integrally formed at the front portion of the second engaging body 40 of the second frame 16, and the bolt 44 is further formed at the front end of the screw insertion groove 45. A circular screw connecting port 46 that allows entry and exit of the operating head is formed. Others are the same as in the first embodiment, so the same members are designated by the same reference numerals and the description thereof will be omitted. The same shall apply in the following examples.

戸パネル３を建込む場合には、戸車６をガイドレール２に落とし込んだ状態で戸パネル３を起立させ、第１フレーム１５が第２フレーム１６と正対する位置まで戸パネル３を移動させる。この状態で戸パネル３を第２フレーム１６に向かって移動させ、第１係合体３０の仮組みガイド部３２に、第２係合体４０の第２の仮組みガイド部８２の前端縁を接当させる。その状態で戸パネル３を第２フレーム１６に向かって押込むことにより、第２フレーム１６が徐々に上向きに押上げられる。仮組みガイド部３２が第２の仮組みガイド部８２の前端縁を潜り抜けるのに連続して、図１４（ａ）に示すように第１係合体３０のパネル側爪部３１の上端が、第２の仮組みガイド部８２の下面を潜り抜け、さらにボルト４４の操作頭部が第２締結座３８の前縁を潜り抜けて、ねじ連結口４６の真下まで移動する。 When the door panel 3 is built, the door panel 3 is erected with the door roller 6 dropped onto the guide rail 2, and the door panel 3 is moved to a position where the first frame 15 faces the second frame 16. In this state, the door panel 3 is moved toward the second frame 16 and the front end edge of the second temporary assembly guide portion 82 of the second engaging body 40 is brought into contact with the temporary assembly guide portion 32 of the first engaging body 30. Let me. By pushing the door panel 3 toward the second frame 16 in that state, the second frame 16 is gradually pushed upward. As shown in FIG. 14A, the upper end of the panel side claw portion 31 of the first engaging body 30 is continuously formed as the temporary assembly guide portion 32 passes through the front end edge of the second temporary assembly guide portion 82. The operation head of the bolt 44 passes through the lower surface of the second temporary assembly guide portion 82, passes through the leading edge of the second fastening seat 38, and moves to just below the screw connecting port 46.

上記の状態では、第２フレーム１６が自重で落下するので、図１４（ｂ）に示すように第２締結座３８は第１締結座２９で支持され、ボルト４４の操作頭部がねじ連結口４６を介して第２締結座３８の上面に突出する。また、第１係合体３０のパネル側爪部３１が、第２係合体４０の壁側爪部４１と正対して仮組み状態に保持される。以後は戸パネル３を押込み操作することで、ボルト４４のねじ軸をねじ挿通溝４５に係合できる。最後に、パネル上部を前後に調整移動して、戸パネル３が垂直姿勢になった状態でボルト４４を締込んで、第２締結座３８と第１締結座２９を固定する。 In the above state, since the second frame 16 falls by its own weight, the second fastening seat 38 is supported by the first fastening seat 29 as shown in FIG. 14 (b), and the operating head of the bolt 44 is the screw connecting port. It projects to the upper surface of the second fastening seat 38 via the 46. Further, the panel-side claw portion 31 of the first engaging body 30 faces the wall-side claw portion 41 of the second engaging body 40 and is held in a temporarily assembled state. After that, by pushing the door panel 3 in, the screw shaft of the bolt 44 can be engaged with the screw insertion groove 45. Finally, the upper part of the panel is adjusted and moved back and forth, and the bolt 44 is tightened in a state where the door panel 3 is in the vertical posture to fix the second fastening seat 38 and the first fastening seat 29.

以上のように、ねじ挿通溝４５とねじ連結口４６が鍵穴状に形成されていると、仮組み状態において、第２フレーム１６の第２締結座３８が外部衝撃を受けて第１締結座２９から浮き離れることがあったとしても、ボルト４４の操作頭部がねじ連結口４６の内面で受止められるので、第１フレーム１５が第２フレーム１６から分離することはなく、仮組み状態を保持し続けることができる。なお、必要があれば、第２の仮組みガイド部８２の外側面に下向きの垂壁を折曲げ形成することができ、その場合には、第１係合体３０の仮組みガイド部３２を垂壁で受止めて、第１係合体３０が横ずれして第２の仮組みガイド部８２の下面から分離するのを解消できる。 As described above, when the screw insertion groove 45 and the screw connecting port 46 are formed in the shape of a keyhole, the second fastening seat 38 of the second frame 16 receives an external impact in the temporarily assembled state, and the first fastening seat 29. Since the operating head of the bolt 44 is received by the inner surface of the screw connecting port 46, the first frame 15 does not separate from the second frame 16 even if it floats away from the second frame 16, and the temporarily assembled state is maintained. Can continue to do. If necessary, a downward hanging wall can be bent and formed on the outer surface of the second temporary assembly guide portion 82, and in that case, the temporary assembly guide portion 32 of the first engaging body 30 is suspended. It can be prevented that the first engaging body 30 is laterally displaced and separated from the lower surface of the second temporary assembly guide portion 82 by being received by the wall.
