Description

本発明は、引戸装置に関し、詳しくは閉じた状態で各引戸が段差無く一列に面一となる引戸装置に関するものである。   The present invention relates to a sliding door device, and more particularly to a sliding door device in which the sliding doors are flush with each other in a closed state.

従来から、3枚引戸の場合、各引戸が各々平行に直進移動して閉状態と右開き状態又は左開き状態となる引き違い式の引戸装置が知られている。   2. Description of the Related Art Conventionally, in the case of three sliding doors, a sliding type sliding door device is known in which each sliding door moves straightly in parallel to be in a closed state, a right open state, or a left open state.

ところが、上記の従来例では、閉状態では手前側から後方にかけて各引戸が段差状となるため、外観上の見栄えが悪いだけでなく、各引戸ごとに上レールの長手方向と直交する前後方向に3本のレール部を並設する必要があり、このため上レールの全体の見込み寸法(奥行き)を大きくとる必要が生じるなど、施工自由度が小さいという制約もあった。   However, in the above-described conventional example, each sliding door has a stepped shape from the front side to the rear side in the closed state, so that not only the appearance is bad, but also for each sliding door in the front-rear direction perpendicular to the longitudinal direction of the upper rail. There is also a restriction that the degree of freedom of construction is small, such as the necessity of arranging three rail portions side by side, and the need to increase the overall expected dimension (depth) of the upper rail.

また、親引戸の表面側に子引戸を開閉方向に移動自在に取付け、親引戸の裏面側に別の子引戸を開閉方向に移動自在に取付け、一方の子引戸を親引戸の表面側に、他方の子引戸を親引戸の裏面側に重ねることで開いた時に大きく開口させることができるようにした引戸装置が特許文献1に示してある。   In addition, a child sliding door is movably attached in the opening / closing direction on the surface side of the main sliding door, another child sliding door is movably attached in the opening / closing direction on the back side of the parent sliding door, and one child sliding door is on the surface side of the parent sliding door, Patent Document 1 discloses a sliding door device that can be largely opened when it is opened by overlapping the other child sliding door on the back side of the parent sliding door.

この特許文献1に示された従来例では、レールの本数を少なくすることが可能であるが、親引戸に子引戸を走行自在にガイドするためのガイド溝、スライダを設ける必要があり、ガイド溝が露出して外観を悪くしてしまう。   In the conventional example shown in this Patent Document 1, it is possible to reduce the number of rails, but it is necessary to provide a guide groove and a slider for guiding the child sliding door so that the main sliding door can run freely. Will be exposed and deteriorate the appearance.

また、2枚引戸において、全閉状態で2枚の引戸が面一に連続し、全閉状態で2枚の引戸が前後に重なるようになったものが特許文献2により知られている。しかしながら、この従来例のものは2枚引戸であり、レールも2枚引戸に対応した前後2列のレール部が必要であり、この2枚引戸、前後2列のレール部という関係をそのまま3枚引戸には適用できない。また、2枚引戸、前後2列のレール部という関係のものにはレール全体の見込み寸法(奥行き寸法)を小さくしようという考え方がそもそも存在しない。
特開平11−229703号公報 実開昭51−103524号公報
Further, Patent Document 2 discloses a two-sliding door in which two sliding doors are flush with each other in the fully closed state, and the two sliding doors overlap each other in the fully closed state. However, this conventional example has two sliding doors, and the rail also requires two rows of rails corresponding to the two sliding doors, and the relationship between the two sliding doors and the rails of the two rows of front and rear is three as it is. Not applicable to sliding doors. In addition, the idea of reducing the expected dimension (depth dimension) of the entire rail does not exist in the first place in relation to the two sliding doors and the two rows of rails.

The left half of the front linear guide rail portion 18b1 also serves as the left half of the curved guide rail portion 18b3, and the intermediate portion inclined in plan view of the curved guide rail portion 18b3 is the rear straight guide rail. Crossing the part 18b2, the middle part and the right half part of the curved guide rail part 18b3 are arranged along the front side of the right inner curved rail part 12.

ここで、図8(b)に示すように、直線ガイドレール部18b1、18b2と、曲進ガイドレール部18b3とは下端の位置が同じ高さ位置であるが、曲進ガイドレール部18b3は高さの高い補助ローラ25bをガイドすることができるように溝深さが深い(上方への凹み深さが深い)ものであり、前の直線ガイドレール部18b1の左側半部は曲進ガイドレール部18b3の左側半部を兼用しているので溝深さが深いが右側半部は溝深さが浅い(上方への凹み深さが浅い)ものである。また、後の直線ガイドレール部18b2は曲進ガイドレール部18b3の中間部が横切っている部分は溝深さが深く、他の部分は溝深さが浅いものであり、これら溝深さの浅い部分の溝底(上底)は高さの高い補助ローラ25bの上端よりも下位置となるように設定してある。したがって、図19(b)のように曲進ガイドレール部18b3の前半部を兼用する前の直線ガイドレール部18b1の左側半部に入った高さの高い補助ローラ25bは直線ガイドレール部18b1の右側半部側には移動できず曲進ガイドレール部18b3の中間部に向かい、更に該中間部を通過する際、後の直線ガイドレール部18b2側にも移動できず、スムーズに後半部にガイドされる。また、図19(a)に示すように、前の直進ガイドレール部18b1は一方引戸1a及び他方引戸1bの各右側端部に取付けた上ランナ21の上面に設けた4個の高さの低い補助ローラ25aのうち前側の2個の高さの低い補助ローラ25aが直進するようにガイドするようになっており、後の直進ガイドレール部18b2は一方引戸1a及び他方引戸1bの各右側端部に取付けた上ランナ21の上面に設けた4個の高さの低い補助ローラ25aのうち後側の2個の高さの低い補助ローラ25aが直進するようにガイドするようになっている。   Here, as shown in FIG. 8B, the straight guide rail portions 18b1 and 18b2 and the curved guide rail portion 18b3 are at the same height, but the curved guide rail portion 18b3 is high. The groove depth is deep so that the high auxiliary roller 25b can be guided (the dent depth is deep upward), and the left half of the front straight guide rail portion 18b1 is a curved guide rail portion. Since the left half portion of 18b3 is also used, the groove depth is deep, but the right half portion has a shallow groove depth (the depth of the upward recess is shallow). Further, the rear straight guide rail portion 18b2 has a deep groove depth at the portion where the intermediate portion of the curved guide rail portion 18b3 crosses, and the other portion has a shallow groove depth, and these groove depths are shallow. The groove bottom (upper bottom) of the portion is set to be lower than the upper end of the high auxiliary roller 25b. Accordingly, as shown in FIG. 19 (b), the high auxiliary roller 25b that enters the left half of the straight guide rail 18b1 that also serves as the front half of the curved guide rail 18b3 is formed on the straight guide rail 18b1. It cannot move to the right half part side but goes to the middle part of the curved guide rail part 18b3, and when passing through the middle part, it cannot move to the rear straight guide rail part 18b2 side, and smoothly guides to the latter half part. Is done. Moreover, as shown to Fig.19 (a), the front rectilinear guide rail part 18b1 is four low provided in the upper surface of the upper runner 21 attached to each right end part of the one sliding door 1a and the other sliding door 1b. The auxiliary rollers 25a on the front side of the auxiliary rollers 25a are guided so as to advance straight, and the rearward guide rail portion 18b2 is provided at the right end of each of the one sliding door 1a and the other sliding door 1b. Among the four low-height auxiliary rollers 25a provided on the upper surface of the upper runner 21 attached to the rear runner, the rear two low-height auxiliary rollers 25a are guided so as to go straight.

ところで、一方引戸1a、他方引戸1bの各右側端部に取付けた上ランナ21の上面に設けた4個の高さの低い補助ローラ25aは前後左右の4個の補助ローラ25aが曲進ガイドレール部18b3を同時に横切らないようになっており、どれかの高さの低い補助ローラ25aが曲進ガイドレール部18b3との交差部分を横切る際に少なくとも前後1個ずつの補助ローラ25aが前の直線ガイドレール部18b1、後の直線ガイドレール部18b2内に位置していて上記交差部分を通過する際に首振りすることなく直進するように構成してある。   By the way, the four auxiliary rollers 25a, which are provided on the upper surface of the upper runner 21 attached to the right end portions of the one sliding door 1a and the other sliding door 1b, have four auxiliary rollers 25a on the front, rear, left and right, which are curved guide rails. The portion 18b3 is not crossed at the same time, and at least one auxiliary roller 25a at the front and rear is a front straight line when any low auxiliary roller 25a crosses the intersection with the bending guide rail portion 18b3. It is located in the guide rail portion 18b1 and the rear straight guide rail portion 18b2, and is configured to go straight without swinging when passing through the intersection.

また、補助レールブロック18cは高さの高い補助ローラ25bをガイドするためのもので、図8(f)に示すように、左側の外側曲進レール部11の前側に沿った下方に開口した溝深さが深い(上方への凹み深さが深い)溝状の曲進ガイドレール部18c1を有している。該曲進ガイドレール部18c1の一端部の開口から他方引戸1bの左側端部に取付けた上ランナ22の上面の前側に片寄って設けた2個の高さの高い補助ローラ25bが挿入されることで、他方引戸1bの上ランナ22を左側の外側曲進レール部11に沿って導入するようになっている。   The auxiliary rail block 18c is for guiding the high auxiliary roller 25b, and as shown in FIG. 8 (f), a groove opened downward along the front side of the left outer curved rail portion 11. It has a groove-shaped curved guide rail portion 18c1 having a deep depth (a deep dent depth). Two high auxiliary rollers 25b provided at the front side of the upper surface of the upper runner 22 attached to the left end of the other sliding door 1b from the opening at one end of the curved guide rail portion 18c1 are inserted. Thus, the upper runner 22 of the other sliding door 1b is introduced along the left outer curved rail portion 11.

また、補助レールブロック18dは、高さの高い前側に片寄った2個の補助ローラ25bが直進するようにガイドすると共に高さの低い前後4個の補助ローラ25aが曲進するようにガイドするためのもので、図8(e)に示すように、両端部及び下方に開口した溝状の直線ガイドレール部18d1を前側に設けると共に、一端が開口し且つ下方に開口した溝状の曲進ガイドレール部18d2を後側に設けてあり、曲進ガイドレール部18d2は左側の内側曲進レール部12の後側に沿うように配設してある。   In addition, the auxiliary rail block 18d guides the two auxiliary rollers 25b offset toward the front side with a high height so that the auxiliary rail block 18d moves straight, and guides the four auxiliary rollers 25a with a low height on the front side so as to bend. As shown in FIG. 8 (e), a groove-shaped bending guide having both ends and a groove-shaped linear guide rail portion 18d1 opened downward is provided on the front side, and one end is opened and opened downward. The rail portion 18d2 is provided on the rear side, and the curved guide rail portion 18d2 is disposed along the rear side of the left inner curved rail portion 12.

ここで、図8(e)に示すように、曲進ガイドレール部18d2は直線ガイドレール部18d1の下端よりも下方に突出して形成してあり、曲進ガイドレール部18d2の下端は高さの低い補助ローラ25aの上端よりも上方に位置している。図21(b)のように、直線ガイドレール部18d1には他方引戸1b及び一方引戸1aの各左側端部に取付けた上ランナ21、22の上面の前側に片寄って設けた高さの高い補助ローラ25bが挿入されることになって他方引戸1b及び一方引戸1aの各左側端部に取付けた上ランナ21、22を直線走行させるようにガイドするようになっている。また、図21(a)のように、曲進ガイドレール部18d2には他方引戸1bの右側端部に取付けた上ランナ22の上面の後側に片寄って設けた2個の高さの低い補助ローラ25bが挿入されることで、他方引戸1bの上ランナ22を左側の内側曲進レール部12に沿って導入するようになっており、この場合、他方引戸1bの右側端部に取付けた上ランナ22の上面の前側に片寄って設けた2個の高さの低い補助ローラ25bは補助レールブロック18dの下面部の上記曲進ガイドレール部18d2の下端よりも上方に凹んだ段落ち部18d3の下方を通過するように構成してある。なお、直線ガイドレール部18d1の下端は上記段落ち部18d3の上底に開口しているため高さの低い補助ローラ25aが直線ガイドレール部18d1内に入り込むことはない。   Here, as shown in FIG. 8E, the curved guide rail portion 18d2 is formed so as to protrude downward from the lower end of the linear guide rail portion 18d1, and the lower end of the curved guide rail portion 18d2 has a height. It is located above the upper end of the low auxiliary roller 25a. As shown in FIG. 21B, the straight guide rail portion 18d1 has a high auxiliary height that is offset from the front side of the upper surfaces of the upper runners 21 and 22 attached to the left side ends of the other sliding door 1b and the one sliding door 1a. The roller 25b is inserted to guide the upper runners 21 and 22 attached to the left side ends of the other sliding door 1b and the one sliding door 1a so as to run linearly. Further, as shown in FIG. 21A, the bending guide rail portion 18d2 includes two low height auxiliary members provided on the rear side of the upper surface of the upper runner 22 attached to the right end portion of the other sliding door 1b. When the roller 25b is inserted, the upper runner 22 of the other sliding door 1b is introduced along the left inner curved rail portion 12. In this case, the upper runner 22 is attached to the right end of the other sliding door 1b. The two auxiliary rollers 25b having a low height provided on the front side of the upper surface of the runner 22 are provided on a stepped portion 18d3 that is recessed above the lower end of the curved guide rail portion 18d2 on the lower surface portion of the auxiliary rail block 18d. It is configured to pass below. Since the lower end of the straight guide rail portion 18d1 is open to the upper bottom of the stepped portion 18d3, the low auxiliary roller 25a does not enter the straight guide rail portion 18d1.

また、補助レールブロック18eは、中央引戸1cの右側に取付けた上ランナ23の上面に設けた高さの低い前後4個の補助ローラ25aが直進するようにガイドすると共に左側に取付けた上ランナ23の上面に設けた高さの高い2個の補助ローラ25bが曲進するようにガイドするためのもので、図8(c)に示すように、両端及び下方に開口した溝状の前後2列の直線ガイドレール部18e1、18e2と、円弧状をした両端及び下方に開口した溝状の曲進ガイドレール部18e3とが設けてある。後の直線ガイドレール部18e2は左側部、右側部がそれぞれ曲進ガイドレール部18e3の左側部、右側部を兼用しており、更に、曲進ガイドレール部18e3の円弧状をした中間部の両端部の平面視で傾斜した部分がそれぞれ前の直線ガイドレール部18e2を横切っており、曲進ガイドレール部18e3の中間部が湾曲レール部13の前側に沿うように配設してある。   Further, the auxiliary rail block 18e guides the four auxiliary rollers 25a having a low height provided on the upper surface of the upper runner 23 attached to the right side of the central sliding door 1c so as to go straight and the upper runner 23 attached to the left side. As shown in FIG. 8 (c), the two auxiliary rollers 25b having a high height provided on the upper surface of the upper and lower rows are formed in two groove-like front and rear rows opened at both ends and below. Linear guide rail portions 18e1 and 18e2 and groove-shaped curved guide rail portions 18e3 that are open at both ends and downward in the shape of an arc. The rear straight guide rail portion 18e2 has a left side portion and a right side portion that are also used as the left side portion and the right side portion of the curved guide rail portion 18e3, respectively. Further, both ends of the arcuate intermediate portion of the curved guide rail portion 18e3. Each of the portions inclined in plan view crosses the front straight guide rail portion 18e2, and an intermediate portion of the bending guide rail portion 18e3 is disposed along the front side of the curved rail portion 13.

ここで、図8(c)のように、直線ガイドレール部18e1、18e2と、曲進ガイドレール部18e3とは下端の位置が同じ高さ位置であるが、曲進ガイドレール部18e3は高さの高い補助ローラ25bをガイドすることができるように溝深さが深い(上方への凹み深さが深い)ものであり、後の直線ガイドレール部18e1の右側部及び左側部は曲進ガイドレール部18e3の右側部及び左側部を兼用しているので溝深さが深いが直線ガイドレール部18e1の中間部は溝深さが浅い(上方への凹み深さが浅い)ものである。また、前の直線ガイドレール部18e2は曲進ガイドレール部18e3の中間部の両端部が横切っている部分は溝深さが深く、他の部分は溝深さが浅いものであり、これら溝深さの浅い部分の溝底(上底)は高さの高い補助ローラ25bの上端よりも下位置となるように設定してある。したがって、図19(d)のように、曲進ガイドレール部18e3の前側部及び後側部を兼用する後の直線ガイドレール部18e1の左側部又は右側部に入った高さの高い補助ローラ25bは直線ガイドレール部18e1の中間部には移動できず曲進ガイドレール部18e3の中間部に向かう。この場合、更に該中間部を通過する際、前の直線ガイドレール部18e2側にも移動できず、スムーズに中間部にガイドされる。また、図19(c)のように、後の直線ガイドレール部18e1は中央引戸1cの右側端部に取付けた上ランナ23の上面に設けた4個の高さの低い補助ローラ25aのうち後側の2個の高さの低い補助ローラ25aが直進するようにガイドするようになっており、前の直線ガイドレール部18e2は中央引戸1cの右側端部に取付けた上ランナ21の上面に設けた4個の高さの低い補助ローラ25aのうち前側の2個の高さの低い補助ローラ25aが直進するようにガイドするようになっている。   Here, as shown in FIG. 8C, the straight guide rail portions 18e1 and 18e2 and the curved guide rail portion 18e3 are at the same height, but the curved guide rail portion 18e3 has a height. The depth of the groove is deep so that the auxiliary roller 25b having a high height can be guided (the depth of the dent is deep upward), and the right and left sides of the rear straight guide rail portion 18e1 are curved guide rails. Since the right side portion and the left side portion of the portion 18e3 are also used, the groove depth is deep, but the intermediate portion of the linear guide rail portion 18e1 has a shallow groove depth (a shallow dent depth is shallow). Further, the front linear guide rail portion 18e2 has a deep groove depth at the portion where both ends of the intermediate portion of the curved guide rail portion 18e3 cross, and the other portion has a shallow groove depth. The shallow groove bottom (upper bottom) is set to be lower than the upper end of the high auxiliary roller 25b. Accordingly, as shown in FIG. 19 (d), the auxiliary roller 25b having a high height that enters the left side or the right side of the straight guide rail 18e1 that also serves as the front and rear sides of the curved guide rail 18e3. Cannot move to the middle part of the straight guide rail part 18e1 but goes to the middle part of the curved guide rail part 18e3. In this case, when passing further through the intermediate portion, it cannot move to the previous straight guide rail portion 18e2 side, and is smoothly guided to the intermediate portion. Further, as shown in FIG. 19C, the rear straight guide rail portion 18e1 is the rear of the four low auxiliary rollers 25a provided on the upper surface of the upper runner 23 attached to the right end of the central sliding door 1c. The two low side auxiliary rollers 25a are guided so as to go straight, and the front linear guide rail portion 18e2 is provided on the upper surface of the upper runner 21 attached to the right end of the central sliding door 1c. Among the four low auxiliary rollers 25a, the front two low auxiliary rollers 25a are guided so as to go straight.

ところで、中央引戸1cの右側端部に取付けた上ランナ21の上面に設けた4個の高さの低い補助ローラ25aは前後左右の4個の補助ローラ25aが曲進ガイドレール部18e3を同時に横切らないようになっており、どれかの高さの低い補助ローラ25aが曲進ガイドレール部18e3との交差部分を横切る際に少なくとも前後1個ずつの補助ローラ25aが前の直線ガイドレール部18e2、後の直線ガイドレール部18e1内に位置していて上記交差部分を通過する際に首振りすることなく直進するように構成してある。   By the way, four auxiliary rollers 25a provided on the upper surface of the upper runner 21 attached to the right end of the central sliding door 1c have four auxiliary rollers 25a on the front, rear, left and right that simultaneously traverse the curved guide rail portion 18e3. When one of the auxiliary rollers 25a having a low height crosses the intersection with the curved guide rail portion 18e3, at least one auxiliary roller 25a at the front and rear is provided with the front linear guide rail portion 18e2, It is located in the rear straight guide rail portion 18e1 and is configured to go straight without swinging when passing through the intersection.

また、補助レールブロック18fは、中央引戸1cの左側に取付けた上ランナ23の上面に設けた高さの高い後側に片寄った2個の補助ローラ25bが直進するようにガイドすると共に右側に取付けた上ランナ23の上面に設けた高さの低い前後4個の補助ローラ25aが曲進するようにガイドするためのもので、図8(d)に示すように、両端部及び下方に開口した溝状の直線ガイドレール部18f1を後側に設けると共に、両端が開口し且つ下方に開口した円弧状をした溝状の曲進ガイドレール部18f2を前側に設けてあり、直線ガイドレール部18f1が後側直進レール部10の後側に沿って配設してあると共に、曲進ガイドレール部18d2が左側の湾曲レール部13の前側に沿って配設してある。   Further, the auxiliary rail block 18f guides the two auxiliary rollers 25b, which are provided on the upper surface of the upper runner 23 attached to the left side of the central sliding door 1c and are offset to the rear side, to move straight, and is attached to the right side. Further, the four front and rear auxiliary rollers 25a provided on the upper surface of the upper runner 23 are guided so as to bend. As shown in FIG. A groove-shaped linear guide rail portion 18f1 is provided on the rear side, and an arcuate groove-shaped curved guide rail portion 18f2 having both ends open and opened downward is provided on the front side. A rear guide rail portion 10 is disposed along the rear side, and a curved guide rail portion 18 d 2 is disposed along the front side of the left curved rail portion 13.

ここで、曲進ガイドレール部18f2は直線ガイドレール部18f1の下端よりも下方に突出して形成してあり、曲進ガイドレール部18f2の下端は高さの低い補助ローラ25aの上端よりも上方に位置している。図20(d)に示すように、直線ガイドレール部18f1には中央引戸1cの左側端部に取付けた上ランナ23の上面の後側に片寄って設けた高さの高い補助ローラ25bが挿入されることになって中央引戸1cの右側端部に取付けた上ランナ23を直線走行させるようにガイドするようになっている。また、図20(c)に示すように、曲進ガイドレール部18f2には中央引戸1cの右側端部に取付けた上ランナ22の上面の前側に片寄って設けた2個の高さの低い補助ローラ25bが挿入されることで、中央引戸1cの右側に取付けた上ランナ23を右側の湾曲レール部13に沿って導入するようになっており、この場合、中央引戸1cの右側端部に取付けた上ランナ22の上面の後側に片寄って設けた2個の高さの低い補助ローラ25bは補助レールブロック18fの下面部の上記曲進ガイドレール部18d2の下端よりも上方に凹んだ段落ち部18f3の下方を通過するように構成してある。なお、直線ガイドレール部18f1の下端は上記段落ち部18f3の上底に開口しているため高さの低い補助ローラ25aが直線ガイドレール部18f1内に入り込むことはない。   Here, the bending guide rail portion 18f2 is formed so as to protrude downward from the lower end of the linear guide rail portion 18f1, and the lower end of the bending guide rail portion 18f2 is higher than the upper end of the auxiliary roller 25a having a low height. positioned. As shown in FIG. 20 (d), an auxiliary roller 25b having a high height is provided in the straight guide rail portion 18f1 so as to be offset from the rear side of the upper surface of the upper runner 23 attached to the left end of the central sliding door 1c. Thus, the upper runner 23 attached to the right end of the central sliding door 1c is guided so as to run in a straight line. As shown in FIG. 20 (c), the curved guide rail portion 18f2 has two low height auxiliary members provided on the front side of the upper surface of the upper runner 22 attached to the right end of the central sliding door 1c. By inserting the roller 25b, the upper runner 23 attached to the right side of the central sliding door 1c is introduced along the curved rail portion 13 on the right side. In this case, the upper runner 23 is attached to the right end of the central sliding door 1c. Further, the two low auxiliary rollers 25b provided on the rear side of the upper surface of the upper runner 22 are stepped down from the lower end of the curved guide rail portion 18d2 on the lower surface portion of the auxiliary rail block 18f. It is configured to pass below the portion 18f3. Since the lower end of the straight guide rail portion 18f1 is open to the upper bottom of the stepped portion 18f3, the auxiliary roller 25a having a low height does not enter the straight guide rail portion 18f1.

次に連動機構15を説明する。   Next, the interlocking mechanism 15 will be described.

本例の一方引戸1a、他方引戸1b、中央引戸1cは、厚み、幅、高さの寸法が略同じものを用いており、各引戸1a〜1cは各々木製の引戸本体30の両側縁に長尺なアルミニウム製の中空筒状の縦縁材31を取付けて構成してある。縦縁材31の上端面にはエンドキャップ33が設けてある。   The sliding door 1a, the other sliding door 1b, and the central sliding door 1c in this example have substantially the same thickness, width, and height, and the sliding doors 1a to 1c are long on both side edges of the wooden sliding door body 30, respectively.

Further, the vertical edge member 31 on the left side of the one sliding door 1 a and the vertical edge member 31 on the right side of the other sliding door 1 b form a finger hook portion 32 g that protrudes outward from the rear part at the front portion of the vertical edge member 31. Further, the vertical edge members 31 on both the left and right sides of the central sliding door 1c are formed with a concave step portion 32e recessed behind the front surface of the sliding door body 30 on the front surface of the outer half, and the three sliding doors 1a to 1c are flush with each other. In the closed state, the finger hook portion 32g of the vertical edge member 31 of the one sliding door 1a and the other sliding door 1b is disposed on the concave step portion 32e and is positioned in front of the outer end portion of the vertical edge member 31 of the central sliding door 1c. It is supposed to overlap. Each vertical edge member 31 of each of the sliding doors 1a to 1c can open and close the sliding doors 1a to 1c by placing fingers on the finger hooking portion 32g and the concave stepped portion 32e, and also serves as a handle.

ここで図11乃至図13に示すように中央引戸1cの左右両端部の夫々の上端面には前後に長い係合溝33cを形成している。また一方引戸1aの右側端部及び他方引戸1bの左側端部(即ち一方引戸1a及び他方引戸の夫々の閉じ方向側の端部)の上端からは係合溝33cに係合可能な係合部材35を後方に向けて突出している。そしてこれら係合溝33cと係合部材35によって連動機構15が構成されている。   Here, as shown in FIG. 11 to FIG. 13, long engagement grooves 33 c are formed on the upper and lower end surfaces of the left and right ends of the central sliding door 1 c. An engagement member that can engage with the engagement groove 33c from the upper end of the right end of the one sliding door 1a and the left end of the other sliding door 1b (that is, the end of each of the one sliding door 1a and the other sliding door in the closing direction). 35 projects rearward. The interlocking mechanism 15 is constituted by the engaging groove 33c and the engaging member 35.

一方引戸1aの係合部材35と他方引戸1bの係合部材35は左右対称であり、各係合部材35は縦片状の引戸取付部35aの上端から横片状の横片部35bを後方に突出した断面L字状の金具からなるアングル35cを備え、横片部35bに係合突部35dを突設して構成してある。アングル35cは引戸取付部75aを一方引戸1a及び他方引戸1bの夫々の上端部の後面にねじのような固着具34bで固着することで取付けられている。   The engaging member 35 of the one sliding door 1a and the engaging member 35 of the other sliding door 1b are bilaterally symmetric, and each engaging member 35 moves the horizontal piece-like horizontal piece portion 35b from the upper end of the vertical piece-like sliding door mounting portion 35a. An angle 35c made of a metal fitting having an L-shaped cross section is provided, and an engaging protrusion 35d is provided to protrude from the horizontal piece 35b. The angle 35c is attached by fixing the sliding door mounting portion 75a to the rear surfaces of the upper ends of the one sliding door 1a and the other sliding door 1b with a fixing tool 34b such as a screw.

アングル35cを一方引戸1a及び他方引戸1bに取付けるにあたって、一方引戸1aの右側端部の上端部の後面及び他方引戸1bの左側端部の上端部の後面には凹部32fを形成している。各凹部32fは縦縁材31の上端部の後面に形成した凹部32fからなる。凹部32fの底面は縦縁材31の後面よりも引戸取付部35aの厚み寸法以上前方に位置している。アングル35cは引戸取付部35aを凹部32fの底面に当てた状態で取付けてあり、これによりアングル35cの引戸取付部35aは凹部32f内に完全に収まるように収納されている。   When attaching the angle 35c to the one sliding door 1a and the other sliding door 1b, a recess 32f is formed on the rear surface of the upper end portion of the right end portion of the one sliding door 1a and the rear surface of the upper end portion of the left end portion of the other sliding door 1b. Each recess 32 f is formed by a recess 32 f formed on the rear surface of the upper end portion of the vertical edge member 31. The bottom surface of the recess 32f is positioned more forward than the rear surface of the vertical edge member 31 by the thickness dimension of the sliding door mounting portion 35a. The angle 35c is attached in a state where the sliding door mounting portion 35a is in contact with the bottom surface of the concave portion 32f, whereby the sliding door mounting portion 35a of the angle 35c is accommodated in the concave portion 32f.

一方引戸1aのアングル35cの横片部35bの後端部は左側方に突出し、また他方引戸1bのアングル35cの横片部35bの後端部は右側方に突出しており、各突出部分には前記係合溝33cに係合しつつ係合溝33cに沿って移動自在となる係合突部35dを下方に向けて突設している。係合突部35dは横片部35bに上下軸回りに回転自在に軸支したローラで構成されている。係合突部35dを構成するローラはゴム等の軟質材料で形成してあり、これにより係合溝33cに係合した連動時の衝撃を緩和でき、またこの連動時の生じる音を小さくできるようにしている。   On the other hand, the rear end of the horizontal piece 35b of the angle 35c of the sliding door 1a protrudes to the left, and the rear end of the horizontal piece 35b of the angle 35c of the other sliding door 1b protrudes to the right. An engaging protrusion 35d that is movable along the engaging groove 33c while engaging with the engaging groove 33c is provided to project downward. The engaging projection 35d is composed of a roller that is rotatably supported on the horizontal piece 35b around the vertical axis. The roller constituting the engaging protrusion 35d is made of a soft material such as rubber, so that the impact at the time of interlocking engaged with the engaging groove 33c can be reduced, and the sound generated at the time of interlocking can be reduced. I have to.

中央引戸1cの右側に形成した一方引戸1a用の係合溝33cと左側に形成した他方引戸1b用の係合溝33cは左右対称であり、各係合溝33cは中央引戸1cの各縦縁材31のエンドキャップ33の上面に形成している。つまり本例ではエンドキャップ33を前記係合部材35の係合突部35dが係合する受け部材としている。   The engagement groove 33c for the one sliding door 1a formed on the right side of the central sliding door 1c and the engagement groove 33c for the other sliding door 1b formed on the left side are symmetrical, and each engagement groove 33c is a vertical edge of the central sliding door 1c. The material 31 is formed on the upper surface of the end cap 33. That is, in this example, the end cap 33 is a receiving member with which the engaging protrusion 35d of the engaging member 35 is engaged.

各係合溝33cは平面視で略L字状の溝からなり、左右方向と平行な溝状で一端が外側方(つまり右側の係合溝33cにあっては右側方であり、左側の係合溝33cにあっては左側方)に開口する突部挿入口33dと、突部挿入口33dの他端から前側に伸びるガイド溝部33eとで構成されている。ガイド溝部33eは前後方向と平行な直線状の溝であり、その前後方向の長さは中央引戸1cの引戸本体30の厚み寸法よりも長くなっている。ここで各係合溝33cのガイド溝部33eの内側の側面(つまり右側の係合溝33cにあっては左側の側面であり、左側の係合溝33cにあっては右側の側面)を押側ガイド面33fとし、且つ外側の側面(つまり右側の係合溝33cにあっては右側の側面であり、左側の係合溝33cにあっては左側の側面)を引側ガイド面33gとすると、押側ガイド面33f及び引側ガイド面33gは共に前後方向と平行な縦面となっている。   Each engagement groove 33c is a substantially L-shaped groove in plan view, and has a groove shape parallel to the left-right direction, and one end is on the outer side (that is, on the right engagement groove 33c, on the right side, and on the left side). The joint groove 33c includes a protrusion insertion port 33d that opens to the left) and a guide groove 33e that extends forward from the other end of the protrusion insertion port 33d. The guide groove 33e is a linear groove parallel to the front-rear direction, and the length in the front-rear direction is longer than the thickness dimension of the sliding door body 30 of the central sliding door 1c. Here, the inner side surface of the guide groove 33e of each engagement groove 33c (that is, the left side surface in the right engagement groove 33c and the right side surface in the left engagement groove 33c) is a push-side guide. When the outer side surface (that is, the right side surface in the case of the right engagement groove 33c and the left side surface in the case of the left engagement groove 33c) is the pulling side guide surface 33g, the push side Both the guide surface 33f and the pull-side guide surface 33g are vertical surfaces parallel to the front-rear direction.

次に動作を説明する。   Next, the operation will be described.

例えば図11(図1(a)、図2(a)、図3)に示す3枚の引戸1a〜1cを面一にして閉じた状態から図12、図13、図14と順に他方引戸1bを一方引戸1a側に向かって移動して他方引戸1bを中央引戸1cの前方側に重なるようにすると、他方引戸1bの上面の左側端部から後方に突出した位置に設けた係合突部35dが、図22のように中央引戸1cの上面の左側端部に設けた係合溝33cの後端部の中央引戸1cから後方に突出した位置にある突部挿入口33dに近接対向し、この状態で更に他方引戸1bを移動すると図23のように他方引戸1bと中央引戸1cとが概ね重なる段階で係合突部35dが突部挿入口33dから係合溝33cの後端部内に挿入されて係合溝33cの押側ガイド面33fの後端部(突部挿入口33dに対向する部分)に当たって係合し、他方引戸1bの係合突部35dで係合溝33cの押側ガイド面33fを押して他方引戸1bの移動に連動して中央引戸1cを右側に移動させながら係合突部35dが係合溝33cの前端側に移動し、図24のように他方引戸1bと中央引戸1cとが前後方向に離反する段階で、係合突部35dは係合溝33cの押側ガイド面33fの前端部に当たって係合した状態で停止する。これにより中央引戸1cは前記他方引戸1bと中央引戸1cとが概ね重なる段階から3枚の引戸1a〜1cを右側に寄せた全開状態となるまでは他方引戸1bと連動して一方引戸1a側に移動する。   For example, from the state where the three sliding doors 1a to 1c shown in FIG. 11 (FIGS. 1A, 2A, and 3) are closed to be flush with each other, the other sliding door 1b in the order of FIGS. Is moved toward the one sliding door 1a side so that the other sliding door 1b overlaps the front side of the central sliding door 1c, the engaging projection 35d provided at a position protruding rearward from the left end of the upper surface of the other sliding door 1b. However, as shown in FIG. 22, it is close to and opposed to the protrusion insertion port 33d at a position protruding rearward from the central sliding door 1c at the rear end of the engagement groove 33c provided at the left end of the upper surface of the central sliding door 1c. When the other sliding door 1b is further moved in the state, the engaging projection 35d is inserted into the rear end portion of the engaging groove 33c from the projection insertion port 33d when the other sliding door 1b and the central sliding door 1c substantially overlap each other as shown in FIG. The rear end portion of the push-side guide surface 33f of the engagement groove 33c (projection insertion port 3 The portion of the sliding door 1b engages with the projection 35d of the other sliding door 1b and pushes the pushing guide surface 33f of the engaging groove 33c to move the central sliding door 1c to the right in conjunction with the movement of the other sliding door 1b. The engagement protrusion 35d moves to the front end side of the engagement groove 33c, and when the other sliding door 1b and the central sliding door 1c are separated in the front-rear direction as shown in FIG. It stops in the state where it hits the front end of the push-side guide surface 33f and is engaged. As a result, the central sliding door 1c is moved to the one sliding door 1a side in conjunction with the other sliding door 1b from the stage where the other sliding door 1b and the central sliding door 1c substantially overlap until the three sliding doors 1a to 1c are fully opened. Moving.

また逆に図14に示す3枚の引戸1a〜1cを右側に寄せた全開状態から図13、図12、図11と順に他方引戸1bを閉じる方向に移動する時、他方引戸1bの係合突部35dは、中央引戸1cが中央の閉じ位置に移動する直前の段階まで図24のように係合溝33cの引側ガイド面33gの後端部に当たって係合した状態となり、この後、他方引戸1bと中央引戸1cとが前後方向に接近し始める段階で係合溝33cの引側ガイド面33gに当たって係合しつつ係合溝33cの前端側に移動し、この後、図23のように中央引戸1cが閉じ位置に完全に移動した段階(他方引戸1bと中央引戸1cの前後方向の接近が終了した段階)で係合溝33cの前端部に至る。これにより中央引戸1cは右側に寄せた全開状態からその閉じ位置である中央に移動するまでは他方引戸1bと連動する。そしてこの中央引戸1cが閉じ位置に完全に移動した段階に達すると、図22のように係合突部35dは係合溝33cの前端部に至って引側ガイド面33gへの当たりがなくなって係合が解除され、突部挿入口33dから外側方に向かって移動する。これにより他方引戸1bは単独で閉位置まで移動することとなる。   Conversely, when the sliding door 1b moves from the fully opened state where the three sliding doors 1a to 1c shown in FIG. 14 are moved to the right side in the direction of closing the other sliding door 1b in the order of FIGS. 13, 12, and 11, the engaging projection of the other sliding door 1b. The portion 35d hits the rear end portion of the pulling guide surface 33g of the engaging groove 33c until the stage immediately before the central sliding door 1c moves to the central closed position, and is engaged with the other sliding door. 1b and the central sliding door 1c are moved toward the front end side of the engaging groove 33c while engaging with the pulling side guide surface 33g of the engaging groove 33c at the stage where they start approaching in the front-rear direction, and thereafter, as shown in FIG. The sliding door 1c reaches the front end of the engaging groove 33c when it has completely moved to the closed position (when the other sliding door 1b and the central sliding door 1c have approached in the front-rear direction). As a result, the central sliding door 1c is interlocked with the other sliding door 1b until the central sliding door 1c moves from the fully opened state brought to the right side to the center which is the closed position. When the central sliding door 1c reaches the closed position, the engaging projection 35d reaches the front end of the engaging groove 33c and does not hit the pulling guide surface 33g as shown in FIG. The joint is released, and the projection moves outward from the protrusion insertion port 33d. Thereby, the other sliding door 1b will move to a closed position independently.

上記構成によれば、他方引戸1bと中央引戸1cとを連動機構15によって連動できるので、中央引戸1cを手で開閉する必要がなくなり、開閉操作がきわめて容易となる。   According to the said structure, since the other sliding door 1b and the center sliding door 1c can be interlock | cooperated by the interlocking mechanism 15, it becomes unnecessary to open and close the center sliding door 1c by hand, and opening / closing operation becomes very easy.

また図1に示すように、中央引戸1cの両端側にそれぞれ係合溝33cを設け、他方引戸1bの左端(把手側)、及び、一方引戸1aの右端(把手側)にそれぞれ係合部材35を設けたので、左開きと右開きのいずれの場合も連動機構15が働く構造となる。つまり、3枚の引戸1a〜1cが一列に段差なく面一に配置された全閉状態で、一方引戸1aを他方引戸1b側に向けて移動することで、他方引戸1b及び中央引戸1cと同様に、連動機構15により中央引戸1cを一方引戸1aに連動して移動できるようになっている。なおこの3枚の引戸1a〜1cを面一にして閉じた状態から一方引戸1aを他方引戸1b側に向かって移動する時、及び3枚の引戸1a〜1cを左側に寄せた全開状態から一方引戸1aを閉じる方向に移動する時には一方引戸1aの係合突部35dが中央引戸1cの右側の係合溝33cに係合するものであるが、この時の係合突部35dの係合溝33cへの係合は上記した他方引戸1b及び中央引戸1cのそれと同様のものであるので説明を省略する。   Further, as shown in FIG. 1, engagement grooves 33c are provided on both ends of the central sliding door 1c, and engaging members 35 are provided on the left end (the handle side) of the other sliding door 1b and the right end (the handle side) of the one sliding door 1a, respectively. Thus, the interlocking mechanism 15 works in both the left and right openings. That is, in the fully closed state in which the three sliding doors 1a to 1c are arranged in a line with no step, the one sliding door 1a is moved toward the other sliding door 1b, so that it is the same as the other sliding door 1b and the central sliding door 1c. In addition, the interlocking mechanism 15 can move the central sliding door 1c in conjunction with the one sliding door 1a. When the one sliding door 1a is moved toward the other sliding door 1b from the closed state where the three sliding doors 1a to 1c are flush with each other, and from the fully opened state where the three sliding doors 1a to 1c are moved to the left side. When the sliding door 1a is moved in the closing direction, the engaging protrusion 35d of the one sliding door 1a is engaged with the engaging groove 33c on the right side of the central sliding door 1c. At this time, the engaging groove of the engaging protrusion 35d is engaged. Since the engagement with 33c is the same as that of the other sliding door 1b and the central sliding door 1c, the description thereof is omitted.

なお、各引戸1の下端部の中央の1箇所には下ローラ27が突設されている。下ローラ27はL形部材60を介して引戸1〜3の各下端部の中央位置に取り付けられている。下ローラ27をガイドする下レール6には、図2乃至図6に示すように、共用レール部101の長手方向Mの両端側から後方Bに向って傾斜した左右の曲進レール部42,43がそれぞれ設けられ、曲進レール部42、43の端部から共用レール部101と平行な下端部直線レール部45が連設してある。共用レール部101と平行で後側に位置する中央引戸用レール部102の中央部から前方Aに向って半円形状に湾曲した1つの湾曲レール部44が設けられている。   Note that a lower roller 27 protrudes from one central portion of the lower end of each sliding door 1. The lower roller 27 is attached to the center position of each lower end portion of the sliding doors 1 to 3 via the L-shaped member 60. As shown in FIGS. 2 to 6, the lower rail 6 that guides the lower roller 27 has left and right curved rail portions 42, 43 that are inclined toward the rear B from both ends in the longitudinal direction M of the common rail portion 101. Are provided, and a lower end straight rail portion 45 parallel to the common rail portion 101 is continuously provided from the end portions of the curved rail portions 42 and 43. One curved rail portion 44 that is curved in a semicircular shape toward the front A from the central portion of the central sliding door rail portion 102 that is parallel to the shared rail portion 101 and located on the rear side is provided.

ここで、下レール6の左側の曲進レール部42の位置は、上レール5の左側の外側曲進レール部11と内側曲進レール部12との中間位置に対向しており、下レール6の右側の曲進レール部43の位置は、上レール5の右側の外側曲進レール部11と内側曲進レール部12との中間位置に対向しており、下レール6の湾曲レール部44の位置は、上レール5の左右の湾曲レール部13,13の中間位置に対向している。   Here, the position of the curved rail portion 42 on the left side of the lower rail 6 is opposed to the intermediate position between the outer curved rail portion 11 and the inner curved rail portion 12 on the left side of the upper rail 5. The position of the right curved rail portion 43 of the upper rail 5 is opposed to the intermediate position between the right outer curved rail portion 11 and the inner curved rail portion 12 of the upper rail 5, and the curved rail portion 44 of the lower rail 6 The position is opposite to the intermediate position between the left and right curved rail portions 13, 13 of the upper rail 5.

そして、各引戸1の上端部は左右2個の上ランナ21(22,23)で吊り下げ支持され、3枚の引戸1が面一となって閉じた状態で、一方引戸1aの下ローラ27が右側の曲進レール部43の後端部に連設した下端部直線レール部45に位置し、中央の引戸1cの下ローラ27が湾曲レール部44の前端部に位置し、他方引戸1bの下ローラ27が左側の曲進レール部42の後端部に連設した下端部直線レール部45に位置する。図14(c)の左開きの場合、一方引戸1aの下ローラ27が右側の曲進レール部43の後端部に位置し、他方引戸1bの下ローラ27が共用レール部101の直線部分の右端に位置し、中央の引戸1cの下ローラ27が中央引戸用レール部102の直線部分の右端に位置する。また、図15(c)の右開きの場合、他方引戸1bの下ローラ27が左側の曲進レール部42の後端部に連設した下端部直線レール部45に位置し、一方引戸1aの下ローラ27が共用レール部101の直線部分の右端に位置し、中央の引戸1cの下ローラ27が中央引戸用レール部102の直線部分の左端に位置する。   And the upper end part of each sliding door 1 is suspended and supported by two right and left upper runners 21 (22, 23), while the three sliding doors 1 are flush and closed, the lower roller 27 of one sliding door 1a. Is located at the lower end linear rail portion 45 connected to the rear end portion of the right curved rail portion 43, the lower roller 27 of the central sliding door 1c is located at the front end portion of the curved rail portion 44, and the other sliding door 1b The lower roller 27 is positioned on the lower end straight rail portion 45 that is connected to the rear end portion of the left curved rail portion 42. 14C, the lower roller 27 of the one sliding door 1a is positioned at the rear end of the right curved rail portion 43, and the lower roller 27 of the other sliding door 1b is a straight portion of the common rail portion 101. The lower roller 27 of the central sliding door 1c is positioned at the right end of the straight portion of the central sliding door rail portion 102. 15 (c), the lower roller 27 of the other sliding door 1b is positioned on the lower end straight rail portion 45 connected to the rear end portion of the left curved rail portion 42, and the one sliding door 1a The lower roller 27 is located at the right end of the straight portion of the common rail portion 101, and the lower roller 27 of the central sliding door 1c is located at the left end of the straight portion of the central sliding door rail portion 102.

上記例において下端部直線レール部45を設けることで前述の上レールに端部直線レール部14を設けたのと同じ作用効果を奏し、一方引戸1a、他方引戸1bが全閉状態でいずれも前後方向において正規の位置になって段差が生じないようにでき、また、開いた状態でも、正常な位置に確実に位置させることができ、全開状態で一方引戸1a又は他方引戸1bが正規の位置よりも前側にずれていて他方引戸1b又は一方引戸1aが閉じる際に衝突したり、擦れたりせず、スムーズに正常な位置に確実に位置させて閉じることができる。   In the above example, the lower end linear rail portion 45 provides the same effect as the end linear rail portion 14 provided on the upper rail, and the sliding door 1a and the other sliding door 1b are fully closed. The normal position in the direction can be prevented from being stepped, and even in the opened state, it can be surely positioned in the normal position. In the fully opened state, the one sliding door 1a or the other sliding door 1b is more than the regular position. Also, the second sliding door 1b or the first sliding door 1a is shifted to the front side, so that it does not collide or rub when closed, and can be smoothly and reliably positioned at the normal position and closed.

このように下端部は1個の下ローラ27で下レール6にガイドされる結果、各引戸1の走行の安定化を十分に図ることができると共に、1個の下ローラ27を用いることで、下レール6の溝形状を上レール5の溝形状よりも簡易にでき、下レール6のコスト低減を図ることができる利点もある。   As described above, the lower end portion is guided to the lower rail 6 by one lower roller 27. As a result, the running of each sliding door 1 can be sufficiently stabilized, and by using one lower roller 27, There is also an advantage that the groove shape of the lower rail 6 can be made simpler than the groove shape of the upper rail 5 and the cost of the lower rail 6 can be reduced.

図25には引戸1の下端部の中央の1箇所に下ローラ27を突設して取付けるためのL形部材60の一実施形態が示してある。   FIG. 25 shows an embodiment of an L-shaped member 60 for projecting and attaching the lower roller 27 to one place at the center of the lower end of the sliding door 1.

図25に示す実施形態においては、引戸固定部材61と、引戸固定部材61に対して上下方向に移動自在となったL形可動部材62とでL形部材60が構成してあり、L形可動部材62には前後方向に移動自在となった横板62dを設けてあり、該横板62dの先端部の下面側に下ローラ27が回転自在に取り付けてある。   In the embodiment shown in FIG. 25, an L-shaped member 60 is configured by a sliding door fixing member 61 and an L-shaped movable member 62 that is movable in the vertical direction with respect to the sliding door fixing member 61. The member 62 is provided with a horizontal plate 62d that is movable in the front-rear direction, and a lower roller 27 is rotatably attached to the lower surface side of the front end portion of the horizontal plate 62d.

引戸固定部材61は引戸1の下端部中央の1箇所に取り付けられるものであり、この引戸固定部材61は下方に開口する凹所64を設けてあり、該凹所64に下開口からL形可動部材62の縦部材62aが上下に移動自在に嵌め込んであり、縦部材62aの上部と凹所64の内の天井部との間にコイルスプリング65が介在してあってL形可動部材62を下方に向けて弾性付勢してある。横板62dはL形可動部材62の横片部62bにスライド自在に重複またはスライド自在に嵌め込まれ、横片部62bに設けた横長孔62cから挿入したねじ具66を横板62dのねじ孔に螺合することで、取り付けてあり、ねじ具66を緩めることでL形可動部材62を前後方向にスライドでき、ねじ具66を締め付けることでスライド位置で固定できるようになっている。   The sliding door fixing member 61 is attached to one place in the center of the lower end portion of the sliding door 1, and this sliding door fixing member 61 is provided with a recess 64 that opens downward, and the recess 64 is movable in an L shape from the lower opening. A vertical member 62a of the member 62 is fitted so as to be movable up and down, and a coil spring 65 is interposed between the upper portion of the vertical member 62a and the ceiling portion of the recess 64, so that the L-shaped movable member 62 is inserted. It is elastically biased downward. The horizontal plate 62d is slidably overlapped or slidably fitted into the horizontal piece portion 62b of the L-shaped movable member 62, and the screw tool 66 inserted from the horizontal elongated hole 62c provided in the horizontal piece portion 62b is used as the screw hole of the horizontal plate 62d. The L-shaped movable member 62 can be slid in the front-rear direction by loosening the screw tool 66, and can be fixed at the slide position by tightening the screw tool 66.

下ローラ27は前述のように下レール6に設けた共用レール部101又は中央引戸用レール部102に走行自在に嵌め込まれるのであるが、この場合、下レール6から引戸1の下面までの寸法が現場毎異なっても、縦部材62aが上下移動自在で且つコイルスプリング65により下方に弾性付勢してあるので、下レール6から引戸1の下面までの寸法の現場毎のばらつきを吸収することができ、また、各引戸1と共用レール部101又は中央引戸用レール部102の平面視における位置関係が現場毎ばらつきがあっても、ねじ具66を緩めてL形可動部材62を前後方向にスライドすることで、各引戸1と共用レール部101又は中央引戸用レール部102の平面視における位置関係の現場毎のばらつきを吸収することができ、これにより、下ローラ27を確実に共用レール部101又は中央引戸用レール部102に走行自在に嵌め込んでスムーズに走行させることができる。   The lower roller 27 is fitted to the common rail portion 101 or the central sliding door rail portion 102 provided on the lower rail 6 as described above so that it can run freely. In this case, the dimension from the lower rail 6 to the lower surface of the sliding door 1 is as follows. Even if it differs from site to site, the vertical member 62a is movable up and down and elastically biased downward by the coil spring 65, so that variations in the size from the lower rail 6 to the lower surface of the sliding door 1 can be absorbed. In addition, even if the positional relationship between each sliding door 1 and the common rail portion 101 or the central sliding door rail portion 102 in plan view varies, the screw tool 66 is loosened and the L-shaped movable member 62 is slid in the front-rear direction. By doing so, it is possible to absorb the variation of each positional relationship in the plan view of each sliding door 1 and the common rail portion 101 or the central sliding door rail portion 102, Can travel smoothly roller 27 is reliably fitted to freely travel the shared rail unit 101 or the central sliding rail portion 102.

また、図26、図27には引戸1の下端部の中央の1箇所に下ローラ27を突設して取付けるためのL形部材60の他の一実施形態が示してある。   FIGS. 26 and 27 show another embodiment of an L-shaped member 60 for projecting and attaching the lower roller 27 to one place at the center of the lower end of the sliding door 1.

本実施形態においては、引戸固定部材61と、引戸固定部材61に対して上下方向に移動自在となったL形可動部材62とでL形部材60が構成してある。本実施形態におけるL形可動部材62は下面側に下ローラ27を回転自在に取り付けた横板62dの前後方向の一端部の左右両端部から上方に向けて一対の棒状の縦部材62aを突設して構成してある。   In the present embodiment, the L-shaped member 60 is configured by the sliding door fixing member 61 and the L-shaped movable member 62 that is movable in the vertical direction with respect to the sliding door fixing member 61. In the present embodiment, the L-shaped movable member 62 has a pair of rod-like vertical members 62a projecting upward from left and right end portions of one end portion in the front-rear direction of the horizontal plate 62d with the lower roller 27 rotatably attached to the lower surface side. Configured.

本実施形態においては引戸固定部材61には下方に開口する凹所64が設けてあり、該凹所64内には左右両端部に上下方向に貫通する挿通孔69aを有する前後移動部材69が上下方向、左右方向には移動しないが、前後方向にのみ移動自在に取り付けてある。図の実施形態では前後移動部材69の中央部に前後に貫通して設けた孔69bを引戸固定部材61に固定したねじ具70に挿通することで、前後移動部材69が上下方向、左右方向には移動しないが、前後方向にのみ移動自在に凹所64内に取り付けてある。前後移動部材69の左右の挿通孔69aには一対の棒状の縦部材62aが上下移動自在に挿通してあり、一対の縦部材62aの上部と凹所64の内の天井部との間にコイルスプリング65が介在してあってL形可動部材62を下方に向けて弾性付勢してある。したがって、L形可動部材62は上下方向に移動自在で且つ下方に向けて弾性付勢してあると共に、前後移動部材69が前後方向に移動可能となっていることでL形可動部材62は前後方向に移動できるようになっている。   In the present embodiment, the sliding door fixing member 61 is provided with a recess 64 that opens downward, and in the recess 64, a longitudinally moving member 69 having insertion holes 69a penetrating vertically at both left and right end portions is provided. Although it does not move in the direction and the left-right direction, it is movably attached only in the front-rear direction. In the illustrated embodiment, the front and rear moving member 69 is moved in the vertical direction and the left and right direction by inserting a hole 69b provided through the central portion of the front and rear moving member 69 through the screw 70 fixed to the sliding door fixing member 61.

A pair of rod-like vertical members 62 a are inserted through the left and right insertion holes 69 a of the front-rear moving member 69 so as to be movable up and down, and a coil is formed between the upper part of the pair of vertical members 62 a and the ceiling portion in the recess 64. A spring 65 is interposed to elastically bias the L-shaped movable member 62 downward. Therefore, the L-shaped movable member 62 is movable in the vertical direction and elastically biased downward, and the L-shaped movable member 62 is movable in the front-rear direction because the front-rear moving member 69 is movable in the front-rear direction. It can be moved in the direction.

下ローラ27は前述のように下レール6に設けた共用レール部101又は中央引戸用レール部102に走行自在に嵌め込まれるのであるが、この場合、下レール6から引戸1の下面までの寸法が現場毎異なっても、L形可動部材62が上下移動自在で且つコイルスプリング65により下方に弾性付勢してあるので、下レール6から引戸1の下面までの寸法の現場毎のばらつきを吸収することができ、また、各引戸1と共用レール部101又は中央引戸用レール部102の平面視における位置関係が現場毎ばらつきがあっても、L形可動部材62は前後方向に移動できるので、各引戸1と共用レール部101又は中央引戸用レール部102の平面視における位置関係の現場毎のばらつきを吸収することができ、これにより、下ローラ27を確実に共用レール部101又は中央引戸用レール部102に走行自在に嵌め込んでスムーズに走行させることができる。   The lower roller 27 is fitted to the common rail portion 101 or the central sliding door rail portion 102 provided on the lower rail 6 as described above so that it can run freely. In this case, the dimension from the lower rail 6 to the lower surface of the sliding door 1 is as follows. Even if it differs from site to site, the L-shaped movable member 62 can move up and down and is elastically biased downward by the coil spring 65, so that variations in the size from the lower rail 6 to the lower surface of the sliding door 1 are absorbed. In addition, even if the positional relationship in plan view of each sliding door 1 and the common rail portion 101 or the central sliding door rail portion 102 varies from site to site, the L-shaped movable member 62 can move in the front-rear direction. Variations in the positional relationship between the sliding door 1 and the common rail portion 101 or the central sliding door rail portion 102 in a plan view can be absorbed, and thus the lower roller 27 can be reliably secured. It can travel smoothly fitted to freely travel the shared rail unit 101 or the central sliding rail portion 102.

引戸固定部材61と、引戸固定部材61に対して上下方向に移動自在となったL形可動部材62とでL形部材60が構成してある。本実施形態におけるL形可動部材62は下面側に下ローラ27を回転自在に取り付けた横板62dの前後方向の一端部の左右両端部から上方に向けて一対の棒状の縦部材62aを突設して構成してある。   An L-shaped member 60 is configured by the sliding door fixing member 61 and the L-shaped movable member 62 that is movable in the vertical direction with respect to the sliding door fixing member 61. In the present embodiment, the L-shaped movable member 62 has a pair of rod-like vertical members 62a projecting upward from left and right end portions of one end portion in the front-rear direction of the horizontal plate 62d with the lower roller 27 rotatably attached to the lower surface side. Configured.

上記L形可動部材62の一対の縦部材62aは前述の引戸の下端部の中央に左右方向に並べて固定された一対の筒体よりなる引戸固定部材61に上下移動自在に嵌め込まれ、一対の縦部材62aの上部と一対の筒体よりなる引戸固定部材61内の上底部との間にコイルスプリング65が介在してあってL形可動部材62を下方に向けて弾性付勢してある。   A pair of vertical members 62a of the L-shaped movable member 62 are fitted to a sliding door fixing member 61 made of a pair of cylindrical bodies fixed in a horizontal direction at the center of the lower end portion of the sliding door, so as to be movable up and down. A coil spring 65 is interposed between the upper part of the member 62a and the upper bottom part in the sliding door fixing member 61 made of a pair of cylinders, and the L-shaped movable member 62 is elastically biased downward.

また、横板62dには前後方向に長い長孔62eが設けてある。下ローラ27は垂直なローラ軸27aの下部に水平回動自在に設けてある。ローラ軸27aの上下方向の中間部にはローラ軸27aよりも大径の座部27bが設けてあり、ローラ軸27aの上部(座部27bよりも上方の部位)は断面四角形状をした角軸部27cとなっており、角軸部27cには上端面に開口するねじ穴27dが設けてある。ローラ軸27aの上部の角軸部27cは横板62dの長孔62eに前後方向にスライドはできるが回転できないように嵌め込んであり、横板62dの上面側においてワッシャ27fを介してねじ具27gをねじ穴27dに上方から螺合することで、ワッシャ27fを介してねじ具27gの頭部と、座部27bとで横板62dを上下から挟持することで横板62dに対してローラ軸27aを取り付けるようになっている。そして、ねじ具27gを緩めることで長孔62eに対してローラ軸27aを前後方向に移動して位置調整ができるようになっており、位置調整をした状態でねじ具27gを固定することで、前後方向に移動しないように固定できる。   The horizontal plate 62d is provided with a long hole 62e that is long in the front-rear direction. The lower roller 27 is provided below the vertical roller shaft 27a so as to be horizontally rotatable. A seat portion 27b having a diameter larger than that of the roller shaft 27a is provided at an intermediate portion in the vertical direction of the roller shaft 27a, and an upper portion of the roller shaft 27a (portion above the seat portion 27b) is a square shaft having a square cross section. This is a portion 27c, and the square shaft portion 27c is provided with a screw hole 27d that opens to the upper end surface. The angular shaft portion 27c on the upper side of the roller shaft 27a is fitted in the elongated hole 62e of the horizontal plate 62d so that it can slide in the front-rear direction but cannot rotate, and the screw 27g is inserted on the upper surface side of the horizontal plate 62d via the washer 27f. Is screwed into the screw hole 27d from above, so that the horizontal plate 62d is sandwiched from above and below by the head portion of the screw tool 27g and the seat portion 27b via the washer 27f, thereby the roller shaft 27a with respect to the horizontal plate 62d. Is supposed to be attached. Then, by loosening the screw tool 27g, the roller shaft 27a can be moved in the front-rear direction with respect to the long hole 62e so that the position can be adjusted. By fixing the screw tool 27g in the position adjusted state, Can be fixed so that it does not move in the front-rear direction.

したがって、L形可動部材62は上下方向に移動自在で且つ下方に向けて弾性付勢してあり、また、下ローラ27を取り付けたローラ軸27aが前後方向に移動可能となっていることで下ローラ27は前後方向に移動して前後方向の位置調整ができるようになっている。   Therefore, the L-shaped movable member 62 is movable in the vertical direction and elastically biased downward, and the roller shaft 27a to which the lower roller 27 is attached is movable in the front-rear direction. The roller 27 moves in the front-rear direction so that the position in the front-rear direction can be adjusted.

下ローラ27は前述のように下レール6に設けた共用レール部101又は中央引戸用レール部102に走行自在に嵌め込まれるのであるが、この場合、下レール6から引戸1の下面までの寸法が現場毎異なっても、L形可動部材62が上下移動自在で且つコイルスプリング65により下方に弾性付勢してあるので、下レール6から引戸1の下面までの寸法の現場毎のばらつきを吸収することができ、また、各引戸1と共用レール部101又は中央引戸用レール部102の平面視における位置関係が現場毎ばらつきがあっても、下ローラ27を取り付けたローラ軸27aの前後方向の位置調整をすることで、各引戸1と共用レール部101又は中央引戸用レール部102の平面視における位置関係の現場毎のばらつきを吸収することができ、これにより、下ローラ27を確実に共用レール部101又は中央引戸用レール部102に走行自在に嵌め込んでスムーズに走行させることができる。   The lower roller 27 is fitted to the common rail portion 101 or the central sliding door rail portion 102 provided on the lower rail 6 as described above so that it can run freely. In this case, the dimension from the lower rail 6 to the lower surface of the sliding door 1 is as follows. Even if it differs from site to site, the L-shaped movable member 62 can move up and down and is elastically biased downward by the coil spring 65, so that variations in the size from the lower rail 6 to the lower surface of the sliding door 1 are absorbed. In addition, even if the positional relationship in plan view of each sliding door 1 and the common rail portion 101 or the central sliding door rail portion 102 varies from site to site, the position in the front-rear direction of the roller shaft 27a to which the lower roller 27 is attached By making adjustments, it is possible to absorb variations in the positional relationship between each sliding door 1 and the common rail portion 101 or the central sliding door rail portion 102 in a plan view. Accordingly, it is possible to travel smoothly fitted to freely travel the lower roller 27 to ensure common rail unit 101 or the central sliding rail portion 102.

また、図29には図28の実施形態の変形例が示してある。つまり、本実施形態は基本的構成が図28の実施形態と同じであるが、ローラ軸27aを横板62dに前後方向に位置調整自在に取り付ける構成が異なるので、この点についてのみ説明する。下ローラ27は垂直なローラ軸27aの下部に水平回動自在に設けてある。ローラ軸27aの上下方向の中間部にはローラ軸27aよりも大径の座部27bが設けてあり、ローラ軸27aの座部27bの上部に断面四角形状をした角軸部27cが設けてあり、更にローラ軸27aの角軸部27cよりも上方の部位(つまりローラ軸27aの上部)が雄ねじ部27hとなっている。ローラ軸27aの上部の角軸部27cは横板62dの長孔62eに前後方向にスライドはできるが回転できないように嵌め込んであり、更に、雄ねじ部27hが横板62d上面から上方に突出してあり、この雄ねじ部27hにナット27iを螺合して、ナット27iと座部27bとで横板62dを上下から挟持することで横板62dに対してローラ軸27aを取り付けるようになっている。そして、ナット27iを緩めることで長孔62eに対してローラ軸27aを前後方向に移動して位置調整ができるようになっており、位置調整をした状態でナット27iを締め付けることで、前後方向に移動しないように固定できる。   FIG. 29 shows a modification of the embodiment of FIG. That is, the basic configuration of this embodiment is the same as that of the embodiment of FIG. 28, but the configuration in which the roller shaft 27a is attached to the horizontal plate 62d so that the position can be adjusted in the front-rear direction is different. The lower roller 27 is provided below the vertical roller shaft 27a so as to be horizontally rotatable. A seat portion 27b having a diameter larger than that of the roller shaft 27a is provided at an intermediate portion in the vertical direction of the roller shaft 27a, and a square shaft portion 27c having a square cross section is provided above the seat portion 27b of the roller shaft 27a. Further, a portion above the angular shaft portion 27c of the roller shaft 27a (that is, the upper portion of the roller shaft 27a) is a male screw portion 27h. The angular shaft portion 27c on the upper side of the roller shaft 27a is fitted in the elongated hole 62e of the horizontal plate 62d so that it can slide in the front-rear direction but cannot rotate, and the male screw portion 27h protrudes upward from the upper surface of the horizontal plate 62d. The nut 27i is screwed onto the male screw portion 27h, and the horizontal plate 62d is sandwiched from above and below by the nut 27i and the seat portion 27b, so that the roller shaft 27a is attached to the horizontal plate 62d. Then, by loosening the nut 27i, the roller shaft 27a can be moved in the front-rear direction with respect to the long hole 62e, and the position can be adjusted. By tightening the nut 27i with the position adjusted, the position in the front-rear direction can be increased. Can be fixed so that it does not move.

したがって、L形可動部材62は上下方向に移動自在で且つ下方に向けて弾性付勢してあり、また、下ローラ27を取り付けたローラ軸27aが前後方向に移動可能となっていることで下ローラ27は前後方向に移動して前後方向の位置調整ができるようになっている。   Therefore, the L-shaped movable member 62 is movable in the vertical direction and elastically biased downward, and the roller shaft 27a to which the lower roller 27 is attached is movable in the front-rear direction. The roller 27 moves in the front-rear direction so that the position in the front-rear direction can be adjusted.
