しかしながら、第１〜第３の扉１０１、１０２、１０３を扉枠に取り付ける前に、無端ベルト１０５に取り付けられた調整板１１０と台盤１０８とをビス１０９で取り付けてしまうと、第２の扉１０２と第１の扉１０１、および、第２の扉１０２と第３の扉１０３が連結されてしまうため、一枚ずつ扉を扉枠に取り付けることが不可能である。そのため、調整板１１０と台盤１０８との間のビス１０９による取り付けは、第１〜第３の扉１０１、１０２、１０３を全て扉枠に取り付けた後に行う必要がある。しかしながら、無端ベルト１０５および固定具１０６は、扉の上端にあり高い位置での作業が必要となり、ただでさえ取り付けが困難となるのに加え、さらに、扉の上端と、扉枠の上側の下端との間にはスペースがそれほどないため、ビスでの取り付け作業はより困難であった。この作業の困難性は、取り付け作業時だけでなく、部材の点検や交換、扉の取り外し時など、無端ベルト１０５と固定具１０６、１０７の取り付けを解除する取り外し時にも生じる。 However, if the adjusting plate 110 attached to the endless belt 105 and the base plate 108 are attached with the screws 109 before the first to third doors 101, 102, 103 are attached to the door frame, the second door. Since 102 and the first door 101, and the second door 102 and the third door 103 are connected, it is impossible to attach the doors to the door frame one by one. Therefore, it is necessary to attach the adjustment plate 110 and the base plate 108 with the screws 109 after all the first to third doors 101, 102, 103 are attached to the door frame. However, the endless belt 105 and the fixture 106 are located at the upper end of the door and need to be operated at a high position, so that it is difficult to attach the endless belt 105 and the fixture 106. Since there was not much space between the two, the installation work with screws was more difficult. The difficulty of this work occurs not only during the attachment work, but also during the removal for releasing the attachment of the endless belt 105 and the fixtures 106 and 107, such as inspection and replacement of members and removal of the door.

図１に示されるように、本実施形態の連動引き戸装置１は、引き戸Ｄ１（第１の引き戸）と、引き戸Ｄ２（第２の引き戸）と、引き戸Ｄ３（第３の引き戸）とを備えている。引き戸Ｄ１、引き戸Ｄ２、引き戸Ｄ３（以下、引き戸Ｄ１、引き戸Ｄ２、引き戸Ｄ３をまとめて引き戸Ｄという）は、互いに対して略平行に設けられている。引き戸Ｄ１、引き戸Ｄ２および引き戸Ｄ３は、所定の幅を有する間口を閉鎖可能であり、間口を開放した状態では、３枚の引き戸Ｄは図１に示されるように、互いに重なった状態となる。３枚の引き戸Ｄが重なった状態において、引き戸Ｄの厚さ方向Ｘ（図１参照）で中央に位置し、引き戸Ｄ２と引き戸Ｄ３に挟まれるように配置されるのが、引き戸Ｄ１であり、引き戸Ｄ１の厚さ方向Ｘの両側に隣接して引き戸Ｄ２および引き戸Ｄ３が位置している。 <First Embodiment>
As FIG. 1 shows, the interlocking sliding door apparatus 1 of this embodiment is equipped with the sliding door D1 (1st sliding door), the sliding door D2 (2nd sliding door), and the sliding door D3 (3rd sliding door). Yes. The sliding door D1, the sliding door D2, and the sliding door D3 (hereinafter, the sliding door D1, the sliding door D2, and the sliding door D3 are collectively referred to as the sliding door D) are provided substantially parallel to each other. The sliding door D1, the sliding door D2, and the sliding door D3 can close the frontage having a predetermined width. When the frontage is opened, the three sliding doors D overlap each other as shown in FIG. In the state where the three sliding doors D are overlapped, the sliding door D1 is located at the center in the thickness direction X (see FIG. 1) of the sliding door D and is arranged so as to be sandwiched between the sliding door D2 and the sliding door D3. The sliding door D2 and the sliding door D3 are located adjacent to both sides in the thickness direction X of the sliding door D1.

これら３枚の引き戸Ｄは、互いに対してスライドするように構成され、本実施形態では、図２に示されるように、引き戸Ｄは、引き戸Ｄの上部側に設けられたレールＲ１、下部側に設けられたレールＲ２に沿ってそれぞれスライドするように構成されている。具体的には、本実施形態では、図１および図２に示されるように、引き戸Ｄの上端に設けられ、レールＲ１に係合して案内される案内部材Ｇを備えている。案内部材Ｇは、本実施形態では図１および図２に示されるように、シリンダ部Ｇａと、シリンダ部Ｇａ内にその一部が収容されるシャフト部Ｇｂとを備えている。シャフト部Ｇｂの上端は、レールＲ１と係合する係合部Ｇｃを備え、引き戸Ｄのスライド時に係合部ＧｃがレールＲ１の溝に案内されながら引き戸Ｄがスライドする。シャフト部Ｇｂの下端側は、シリンダ部Ｇａ内に収容され、シリンダ部Ｇａ内に、シャフト部ＧｂをレールＲ１の溝内に向かって（上方に向かって）付勢するバネ等の付勢部材（図示せず）が設けられている。引き戸ＤをレールＲ１に取り付けるときには、係合部ＧｃをレールＲ１の溝に押し付けると、シャフト部Ｇｂは付勢部材の付勢力に抗してシリンダ部Ｇａ内に押し込まれ、引き戸ＤをレールＲ１に取り付けると、付勢部材の付勢力により、シャフト部ＧｂはレールＲ１の溝に向かって突出する。これにより、引き戸ＤのレールＲ１への着脱が容易になる。 These three sliding doors D are configured to slide relative to each other. In the present embodiment, as shown in FIG. 2, the sliding door D is provided on the rail R1 provided on the upper side of the sliding door D and on the lower side. Each is configured to slide along the provided rail R2. Specifically, in this embodiment, as shown in FIG. 1 and FIG. 2, a guide member G provided at the upper end of the sliding door D and guided by engaging with the rail R1 is provided. As shown in FIGS. 1 and 2, the guide member G includes a cylinder part Ga and a shaft part Gb in which a part of the guide member G is accommodated in the cylinder part Ga. The upper end of the shaft portion Gb is provided with an engaging portion Gc that engages with the rail R1, and the sliding door D slides while the engaging portion Gc is guided by the groove of the rail R1 when the sliding door D slides. The lower end side of the shaft part Gb is accommodated in the cylinder part Ga, and an urging member such as a spring for urging the shaft part Gb into the groove of the rail R1 (upward) in the cylinder part Ga ( (Not shown) is provided. When attaching the sliding door D to the rail R1, when the engaging portion Gc is pressed against the groove of the rail R1, the shaft portion Gb is pushed into the cylinder portion Ga against the urging force of the urging member, and the sliding door D is moved to the rail R1. When attached, the shaft portion Gb protrudes toward the groove of the rail R1 by the urging force of the urging member. Thereby, attachment / detachment of the sliding door D to the rail R1 becomes easy.

引き戸Ｄの下部には、本実施形態では、図２に示されるように、レールＲ２上を転動する戸車Ｗが設けられている。戸車Ｗは公知の戸車を用いることができる。なお、引き戸Ｄは互いに対してスライド移動が可能であればよく、引き戸ＤをスライドさせるためのレールＲ１、Ｒ２、案内部材Ｇ、戸車Ｗ等の引き戸Ｄの案内機構は、本実施形態で示したものに限定されるものではない。例えば、引き戸Ｄの上部側に滑動ローラーおよび滑動ローラーが転動可能なレールを設けてもよいし、溝状の上下のレールに係合する突出部を引き戸Ｄの上下に設けてもよい。また、引き戸Ｄは吊り戸としても構わない。 In the present embodiment, as shown in FIG. 2, a door wheel W that rolls on the rail R 2 is provided below the sliding door D. As the door cart W, a publicly known door cart can be used. In addition, the sliding door D should just be slidable with respect to each other, and the guide mechanism of the sliding door D such as the rails R1, R2, the guide member G, and the door pulley W for sliding the sliding door D is shown in this embodiment. It is not limited to things. For example, a sliding roller and a rail on which the sliding roller can roll may be provided on the upper side of the sliding door D, and protrusions that engage with the groove-like upper and lower rails may be provided on the upper and lower sides of the sliding door D. The sliding door D may be a hanging door.

また、引き戸Ｄ同士を連動させる連動機構として、図１および図３に示されるように、引き戸Ｄ１（第１の引き戸）の上端面ＵＳ側または下端面ＬＳ側に、引き戸Ｄ１のスライド方向Ｙ（図１参照）で互いに離間して設けられた一対の方向転換部材２ａ、２ｂと、一対の方向転換部材２ａ、２ｂにループ状にかけ回される伝動部材３と、引き戸Ｄ２（第２の引き戸）に取り付けられ、伝動部材３に直接または間接的に連結される連結部材４ａとを備えている。また、連結機構は、引き戸Ｄ３（第３の引き戸）にも取り付けられ、伝動部材３に連結される第２の連結部材４ｂを備えている。なお、以下、連結部材４ａおよび第２の連結部材４ｂをまとめて単に連結部材４という。 Moreover, as an interlocking mechanism for interlocking the sliding doors D, as shown in FIGS. 1 and 3, the sliding door D1 slide direction Y (on the upper end surface US side or the lower end surface LS side of the sliding door D1 (first sliding door)). 1), a pair of direction changing members 2a and 2b provided apart from each other, a transmission member 3 looped around the pair of direction changing members 2a and 2b, and a sliding door D2 (second sliding door). And a connecting member 4a connected to the transmission member 3 directly or indirectly. Further, the coupling mechanism includes a second coupling member 4 b that is attached to the sliding door D 3 (third sliding door) and coupled to the transmission member 3. Hereinafter, the connecting member 4a and the second connecting member 4b are collectively referred to simply as the connecting member 4.

連動機構は、図４（ａ）〜（ｃ）の模式図に示されるように、１枚の引き戸をスライドさせると、もう１枚の引き戸が連動してスライドするように構成されている。具体的には、引き戸Ｄ１に隣接する引き戸Ｄ２を図４（ａ）中、右方向にスライドさせると、引き戸Ｄ２に取り付けられた連結部材４ａは、引き戸Ｄ２のスライドに応じて、図４（ａ）に示される初期位置から、図４（ｂ）に示されるように、スライド方向（右方向）に移動する。連結部材４ａが右側に移動すると、連結部材４ａの移動に伴って、連結部材４ａが取り付けられた伝動部材３は図４（ｂ）中、反時計回りに回動する。一方、引き戸Ｄ３は、第２の連結部材４ｂにより伝動部材３に連結されているが、引き戸Ｄ３の重量および伝動部材３が反時計回りに回転しているため、引き戸Ｄ３は紙面上左方向に付勢され、引き戸Ｄ３は移動することがない。伝動部材３の連結部材４ａとの接続箇所から伝動部材３の第２の連結部材４ｂとの接続箇所までの伝動部材３の長さは変わらないため、伝動部材３が反時計回りに回動しながら、引き戸Ｄ１は引き戸Ｄ２と同方向に、すなわち右側に連動してスライドする（図４（ｂ）および（ｃ）参照）。これにより、引き戸Ｄ１、引き戸Ｄ２および引き戸Ｄ３により開口を閉鎖することができる。引き戸Ｄ２を、図４（ｃ）に示す状態から開放していく場合も、同様に図４（ｂ）、図４（ａ）の状態へと、引き戸Ｄ１が引き戸Ｄ２に連動する。また、なお、引き戸Ｄ３が壁等の据付型の構造物（壁部）であっても、構造物に第２の連結部材４ｂを設けることなどにより、引き戸Ｄ１と引き戸Ｄ２を連動させることができる。 As shown in the schematic diagrams of FIGS. 4A to 4C, the interlocking mechanism is configured such that when one sliding door is slid, the other sliding door is slid in conjunction. Specifically, when the sliding door D2 adjacent to the sliding door D1 is slid to the right in FIG. 4A, the connecting member 4a attached to the sliding door D2 corresponds to the sliding of the sliding door D2, as shown in FIG. ) From the initial position shown in FIG. 4B to the slide direction (right direction) as shown in FIG. When the connecting member 4a moves to the right side, the transmission member 3 to which the connecting member 4a is attached rotates counterclockwise in FIG. 4B as the connecting member 4a moves. On the other hand, the sliding door D3 is connected to the transmission member 3 by the second connecting member 4b. However, because the weight of the sliding door D3 and the transmission member 3 are rotated counterclockwise, the sliding door D3 is leftward on the page. Energized, the sliding door D3 does not move. Since the length of the transmission member 3 from the connection point of the transmission member 3 to the connection member 4a to the connection point of the transmission member 3 to the second connection member 4b does not change, the transmission member 3 rotates counterclockwise. However, the sliding door D1 slides in the same direction as the sliding door D2, that is, in conjunction with the right side (see FIGS. 4B and 4C). Thereby, opening can be closed with sliding door D1, sliding door D2, and sliding door D3. Similarly, when the sliding door D2 is opened from the state shown in FIG. 4C, the sliding door D1 is interlocked with the sliding door D2 to the states shown in FIGS. 4B and 4A. In addition, even if the sliding door D3 is an installation type structure (wall portion) such as a wall, the sliding door D1 and the sliding door D2 can be interlocked by providing the structure with the second connecting member 4b. .

連結機構に用いられる伝動部材３は、引き戸Ｄの上述した連動を実現するために、連結部材４と連結されて、一対の方向転換部材２ａ、２ｂに案内されて回動する動力伝達部材である。伝動部材３は、本実施形態では、図１および図３に示されるように、ラック部３ａを有する歯付ベルト（以下、歯付ベルト３という場合がある）であるが、回動して動力を伝達し、上述した引き戸Ｄの連動を実現できるものであれば、歯付ベルトに限定されるものではなく、例えば、単なるベルト等の帯状体、ワイヤ、ロープ、紐等の長尺部材であってもよい。また、伝動部材３は、予め無端状のループに成形された伝動部材を用いてもよいが、後述するように、ループを形成しない１つまたは２つ以上の直線状の長尺部材の端部を接続することにより、ループ状に形成してもよい。 The transmission member 3 used in the connection mechanism is a power transmission member that is connected to the connection member 4 and rotated while being guided by the pair of direction changing members 2a and 2b in order to realize the above-described interlocking of the sliding door D. . In this embodiment, the transmission member 3 is a toothed belt having a rack portion 3a (hereinafter sometimes referred to as a toothed belt 3) as shown in FIG. 1 and FIG. Is not limited to a toothed belt as long as it can realize the interlocking of the sliding door D described above, for example, a belt-like belt or the like, or a long member such as a wire, rope, or string. May be. The transmission member 3 may be a transmission member formed in an endless loop in advance, but as will be described later, the end of one or more linear long members that do not form a loop. May be formed in a loop shape by connecting.

伝動部材３は、図１〜図３に示されるように、一対の方向転換部材２ａ、２ｂにかけ回される。方向転換部材２ａ、２ｂは、伝動部材３が回動できるように、伝動部材３を案内する。本実施形態では、方向転換部材２ａ、２ｂは引き戸Ｄ１の上端面ＵＳに取り付けられている。なお、方向転換部材２ａ、２ｂは引き戸Ｄ１の下端面ＬＳに設けられていてもよい。なお、本明細書において、引き戸Ｄ１の「上端面ＵＳ側」、「下端面ＬＳ側」に設けられるという場合、方向転換部材２ａ、２ｂが取り付けられる部位が、引き戸Ｄ１の上端面ＵＳまたは下端面ＬＳ以外に、例えば、方向転換部材２ａ、２ｂが取り付けられた後に、方向転換部材２ａ、２ｂを覆うカバー等により、方向転換部材２ａ、２ｂの上方に新たな面が形成された場合など、上端面ＵＳまたは下端面ＬＳの近傍に方向転換部材２ａ、２ｂが設けられたものも含む。 As shown in FIGS. 1 to 3, the transmission member 3 is wound around the pair of direction changing members 2 a and 2 b. The direction changing members 2a and 2b guide the transmission member 3 so that the transmission member 3 can rotate. In this embodiment, the direction change members 2a and 2b are attached to the upper end surface US of the sliding door D1. The direction changing members 2a and 2b may be provided on the lower end surface LS of the sliding door D1. In this specification, when the sliding door D1 is provided on the “upper end surface US side” and the “lower end surface LS side”, the portion to which the direction changing members 2a and 2b are attached is the upper end surface US or the lower end surface of the sliding door D1. Other than LS, for example, when a new surface is formed above the direction change members 2a, 2b by a cover or the like that covers the direction change members 2a, 2b after the direction change members 2a, 2b are attached. Also included are those in which the direction changing members 2a and 2b are provided in the vicinity of the end face US or the lower end face LS.

方向転換部材２ａ、２ｂは、伝動部材３が回動するように案内することができれば、回転するものであっても、回転しないものであってもよいが、本実施形態では、垂直軸周りに回転するギヤローラー（以下、ギヤローラー２ａ、２ｂという場合がある）が用いられている。ギヤローラーは、図１および図２に示されるように、外周にギヤが形成されており、歯付ベルト３を案内している。本実施形態では、ギヤローラー２ａ、２ｂの上部には、図１に示されるように、フランジ部２１が設けられている。フランジ部２１は、ギヤローラー２ａ、２ｂの軸心からギヤローラー２ａ、２ｂの歯先を結んだ円の外周を越えて水平方向に突出するように形成されている。歯付ベルト３は、引き戸Ｄの開閉動作に伴って回動するときに、ギヤローラー２ａ、２ｂの軸方向、すなわち本実施形態では上方向に移動してしまうことが実験により明らかとなり、その歯付ベルト３の上方向への動作をフランジ部２１により規制することができる。なお、フランジ部２１は本実施形態では、ギヤローラー２ａ、２ｂの歯先を結んだ円の径よりも大径の円盤状のフランジ部２１が示されているが、フランジ部２１は円盤状に限定されるものではなく、矩形状等、他の形状であってもよい。 The direction changing members 2a and 2b may be either rotating or non-rotating as long as the transmission member 3 can be guided so as to rotate. A rotating gear roller (hereinafter sometimes referred to as gear rollers 2a and 2b) is used. As shown in FIGS. 1 and 2, the gear roller has a gear formed on the outer periphery and guides the toothed belt 3. In the present embodiment, a flange portion 21 is provided on the upper part of the gear rollers 2a and 2b as shown in FIG. The flange portion 21 is formed so as to protrude in the horizontal direction from the axial center of the gear rollers 2a and 2b beyond the outer periphery of a circle connecting the tooth tips of the gear rollers 2a and 2b. It is clear from experiments that the toothed belt 3 moves in the axial direction of the gear rollers 2a and 2b, that is, upward in this embodiment, when the toothed belt 3 rotates in accordance with the opening / closing operation of the sliding door D. The upward movement of the attached belt 3 can be restricted by the flange portion 21. In the present embodiment, the flange portion 21 is a disc-shaped flange portion 21 having a diameter larger than the diameter of the circle connecting the tooth tips of the gear rollers 2a and 2b. It is not limited, and other shapes such as a rectangular shape may be used.

引き戸Ｄ１上に設けられた伝動部材３は、連結部材４と直接または間接的に連結され、伝動部材３が設けられた引き戸に隣接する引き戸を接続する。本実施形態では、伝動部材３が、連結部材４と連結されることにより、引き戸Ｄ１と、隣接する引き戸Ｄ２および引き戸Ｄ３とを接続する。連結部材４は、伝動部材３が設けられる１つの引き戸に隣接する他の引き戸（または壁部などの構造物）に取り付けられる。すなわち、本実施形態では、連結部材４ａは引き戸Ｄ２に取り付けられ、第２の連結部材４ｂは引き戸Ｄ３に取り付けられる。本実施形態では、図１および図３に示されるように、連結部材４ａ、第２の連結部材４ｂはそれぞれ引き戸Ｄ２、引き戸Ｄ３の上端面ＵＳにネジにより固定されている。しかしながら、連結部材４ａ、４ｂは伝動部材３に直接または間接的に取付けが可能であれば、引き戸Ｄ２、引き戸Ｄ３への取付位置は、上端面ＵＳに限定されることはなく、引き戸Ｄの側面（引き戸Ｄ同士が対向する面）等の上端面ＵＳ側に取り付けられていてもよい。また、伝動部材３が引き戸Ｄの下端側に設けられる場合は、下端面ＬＳ側に設けられていてもよい。連結部材４の取付手段は、ネジに限定されるものではなく、接着剤等、他の公知の取付手段を用いることができる。 The transmission member 3 provided on the sliding door D1 is directly or indirectly connected to the connecting member 4, and connects the sliding door adjacent to the sliding door provided with the transmission member 3. In this embodiment, the transmission member 3 is connected to the connecting member 4 to connect the sliding door D1 to the adjacent sliding door D2 and the sliding door D3. The connecting member 4 is attached to another sliding door (or a structure such as a wall) adjacent to one sliding door on which the transmission member 3 is provided. That is, in the present embodiment, the connecting member 4a is attached to the sliding door D2, and the second connecting member 4b is attached to the sliding door D3. In this embodiment, as shown in FIGS. 1 and 3, the connecting member 4a and the second connecting member 4b are fixed to the upper end surface US of the sliding door D2 and the sliding door D3 by screws, respectively. However, if the connecting members 4a and 4b can be directly or indirectly attached to the transmission member 3, the attachment position to the sliding door D2 and the sliding door D3 is not limited to the upper end surface US, and the side surface of the sliding door D is not limited. (The surface where the sliding doors D face each other) or the like may be attached to the upper end surface US side. Moreover, when the transmission member 3 is provided on the lower end side of the sliding door D, it may be provided on the lower end surface LS side. The attachment means of the connecting member 4 is not limited to screws, and other known attachment means such as an adhesive can be used.

本実施形態の連動引き戸装置１では、連結部材４と伝動部材３とは、磁力により互いに連結するように構成されている。上述したように、引き戸ＤをレールＲ１、Ｒ２など、引き戸Ｄにより閉鎖される開口に取り付ける際に、２枚または３枚の引き戸Ｄを一度に取り付けることは非常に困難である。そのため、引き戸Ｄを開口に取り付ける前に予め伝動部材３と連結部材４とを取り付けることは事実上不可能であり、引き戸Ｄを１枚ずつ、開口に取り付けた後に、伝動部材３と連結部材４を取り付ける必要が生じる。そして、伝動部材３および連結部材４は引き戸Ｄの上端側または下端側に設けられるため、伝動部材３と連結部材４とを連結する箇所においては、非常に限られたスペースしか存在しない。この場合に、ビスでの取り付けは非常に困難であり、ビスを取り付ける向きが垂直方向である場合は、ドライバーが入る隙間がなく、特殊な工具が必要となるし、連結部材４を伝動部材３に対して水平方向に取り付けるようにビスをねじ込む際には、伝動部材３、連結部材４の両方を手で持ったうえで、連結部材４が伝動部材３から外れないように支持しながら取り付ける必要がある。このように、伝動部材３と連結部材４との現場での取り付けが非常に煩雑であるうえ、取り付けるためのスペースが限られており、そのうえ、引き戸Ｄの上端などは高所での作業となるので、より一層作業が困難となる。また、このような作業は、取付時だけでなく、掃除やメンテナンス等、引き戸Ｄを取り外す際にも生じ、従来の構成では、１枚ずつ簡単に引き戸Ｄを取り外すこともできない。 In the interlocking sliding door device 1 of the present embodiment, the connecting member 4 and the transmission member 3 are configured to be connected to each other by magnetic force. As described above, when the sliding door D is attached to the opening closed by the sliding door D, such as the rails R1 and R2, it is very difficult to attach two or three sliding doors D at a time. Therefore, it is practically impossible to attach the transmission member 3 and the connecting member 4 in advance before attaching the sliding door D to the opening. After the sliding doors D are attached to the opening one by one, the transmission member 3 and the connecting member 4 are attached. Need to be installed. And since the transmission member 3 and the connection member 4 are provided in the upper end side or lower end side of the sliding door D, in the location which connects the transmission member 3 and the connection member 4, only very limited space exists. In this case, it is very difficult to attach with a screw. When the screw is attached in the vertical direction, there is no space for a screwdriver to enter, a special tool is required, and the connecting member 4 is connected to the transmission member 3. When screwing a screw so as to be mounted horizontally, it is necessary to hold both the transmission member 3 and the connection member 4 by hand and support the connection member 4 so that it does not come off the transmission member 3. There is. As described above, the installation of the transmission member 3 and the connecting member 4 on the site is very complicated, and the space for the installation is limited. In addition, the upper end of the sliding door D is a work at a high place. Therefore, the work becomes even more difficult. Such work occurs not only at the time of attachment but also when removing the sliding door D, such as cleaning and maintenance, and in the conventional configuration, the sliding door D cannot be easily removed one by one.

本実施形態では、伝動部材３と連結部材４とを磁力により吸着させて互いに連結することにより、引き戸Ｄの取付時、取り外し時に引き戸Ｄを容易に取り付け、取り外しすることができ、現場での作業性も大きく向上する。引き戸Ｄの取付作業について詳細に説明すると（引き戸Ｄの取り付けの順番は特に限定されないが）、例えば、引き戸Ｄ１を開口にまず取り付けた場合、次に引き戸Ｄ２を取り付ける。そして、本実施形態では、連結部材４ａを磁力により、伝動部材３との連結箇所で対向させ、磁力の吸着力により、連結部位で連結部材４ａと伝動部材３とが互いに吸着されて、非常に簡単に連結される。次に、引き戸Ｄ３を取り付けた後、同様に第２の連結部材４ｂを磁力により、伝動部材３との連結箇所で対向させ、磁力の吸着力により、連結部位で第２の連結部材４ｂと伝動部材３とが非常に簡単に連結させる。このように磁力の吸着力により伝動部材３と連結部材４を連結することができるので、狭い作業スペースであっても簡単に連結が可能となり、ビス等をねじ込む作業スペースや、部材を外れないように保持しながらビスをねじ込むような手間も必要がない。引き戸Ｄの１枚を取り外したい場合には、磁力に抗して伝動部材３と連結部材４を引き離すだけであるので、取り外しも非常に簡単である。 In this embodiment, the transmission member 3 and the connecting member 4 are attracted by a magnetic force and connected to each other, so that the sliding door D can be easily attached and detached when the sliding door D is attached or removed, and work in the field The characteristics are greatly improved. The attachment operation of the sliding door D will be described in detail (the order of attaching the sliding door D is not particularly limited). For example, when the sliding door D1 is first attached to the opening, the sliding door D2 is then attached. In the present embodiment, the connecting member 4a is opposed to the transmission member 3 by a magnetic force, and the connecting member 4a and the transmission member 3 are adsorbed to each other at the connection portion by the magnetic attraction force. Easy to connect. Next, after attaching the sliding door D3, similarly, the second connecting member 4b is opposed to the transmission member 3 by a magnetic force at a connecting portion, and is transmitted to the second connecting member 4b at the connecting portion by a magnetic adsorption force. The member 3 is connected very easily. Since the transmission member 3 and the connecting member 4 can be connected by the magnetic attraction force in this way, the connection can be easily performed even in a narrow work space, so that the work space for screwing screws or the like does not come off. There is no need to screw in the screw while holding it. When it is desired to remove one of the sliding doors D, the transmission member 3 and the connecting member 4 are simply pulled apart against the magnetic force, so that the removal is very simple.

なお、伝動部材３と連結部材４とは、本実施形態では、図１および図３に示されるように、伝動部材３の長手方向の少なくとも１箇所に設けられる被連結部材５を介して連結されている。被連結部材５は、伝動部材３に予め一体に設けてもよいし、伝動部材３に取り付けても構わない。また、本実施形態では、被連結部材５を介して、伝動部材３と連結部材４とを間接的に連結しているが、例えば、伝動部材３を、磁性粉を混入させた磁性伝動部材とすることにより、例えば磁石を有する連結部材４と直接的に連結することもできる。 In this embodiment, the transmission member 3 and the connecting member 4 are connected via a connected member 5 provided in at least one place in the longitudinal direction of the transmission member 3 as shown in FIGS. 1 and 3. ing. The connected member 5 may be provided integrally with the transmission member 3 in advance or may be attached to the transmission member 3. Moreover, in this embodiment, although the transmission member 3 and the connection member 4 are indirectly connected through the to-be-connected member 5, for example, the transmission member 3 includes a magnetic transmission member mixed with magnetic powder and By doing so, for example, it is possible to directly connect to the connecting member 4 having a magnet.

連結部材４および連結部材４に連結される被連結部材５は、図５（ａ）および（ｂ）に示されるように、一方が磁石Ｍを備え、他方が磁石Ｍに吸着される磁性体（たとえば、鉄等の強磁性体）または第２の磁石を備え、連結部材４と被連結部材５が対向したときに磁力により吸着されて連結される。本実施形態では、図５（ａ）および（ｂ）に示されるように、被連結部材５側に磁石Ｍが設けられ、連結部材４が磁性体により形成されている。しかしながら、連結部材４側に磁石が設けられ、被連結部材５側に磁性体が設けられてもよいし、連結部材４および被連結部材５の両方が磁石を有していてもよい。また、本実施形態では、連結部材４は磁性体により形成されているが、磁性体が設けられる部材（連結部材４または被連結部材５）の一部に磁性体を有していてもよく、例えば、樹脂製の連結部材４の一部に磁石と吸着される磁性体を取り付けてもよい。また、例えばベルト状の伝動部材３など、磁石（または磁性体）を取り付け可能な面を有する伝動部材３に、直接磁石（または磁性体）を取り付けてもよい。 As shown in FIGS. 5 (a) and 5 (b), the connecting member 4 and the connected member 5 connected to the connecting member 4 are each provided with a magnet M, and the other is a magnetic body that is attracted to the magnet M ( For example, a ferromagnetic material such as iron) or a second magnet is provided, and when the connecting member 4 and the connected member 5 face each other, they are attracted and connected by magnetic force. In the present embodiment, as shown in FIGS. 5A and 5B, the magnet M is provided on the coupled member 5 side, and the coupling member 4 is formed of a magnetic material. However, a magnet may be provided on the connecting member 4 side, a magnetic body may be provided on the connected member 5 side, and both the connecting member 4 and the connected member 5 may have magnets. Moreover, in this embodiment, although the connection member 4 is formed with the magnetic body, you may have a magnetic body in some members (the connection member 4 or the to-be-connected member 5) in which a magnetic body is provided, For example, you may attach the magnetic body attracted | sucked to a part of resin-made connection member 4 with a magnet. Moreover, you may attach a magnet (or magnetic body) directly to the transmission member 3 which has the surface which can attach a magnet (or magnetic body), such as the belt-shaped transmission member 3, for example.

被連結部材５は、引き戸Ｄの取り付け前に予め伝動部材３に取り付けられ、引き戸Ｄの取付時に連結部材４と磁力により連結される。上述したように、連結部材４の一方が磁石を備え、他方が磁石に吸着される磁性体または第２の磁石を備えている場合、図５（ａ）および（ｂ）に示されるように、連結部材４と、被連結部材５とが対向する位置に引き戸Ｄをスライドさせるか、伝動部材３を回動させるという簡単な動作で、連結部材４と被連結部材５との間の連結作業を行うことができる。すなわち、図５（ａ）に示されるように、連結部材４と、被連結部材５との間の位置が引き戸Ｄのスライド方向Ｙでずれている場合であっても、引き戸Ｄをスライドさせるか、伝動部材３を回動させるかして、被連結部材５が連結部材４に対向する位置に移動させると、磁力により互いに吸着され、連結部材４と被連結部材５との間の連結を簡単に行うことができる。 The connected member 5 is attached to the transmission member 3 in advance before the sliding door D is attached, and is connected to the connecting member 4 by a magnetic force when the sliding door D is attached. As described above, when one of the connecting members 4 includes a magnet and the other includes a magnetic body or a second magnet that is attracted to the magnet, as shown in FIGS. 5A and 5B, The connecting operation between the connecting member 4 and the connected member 5 can be performed by a simple operation of sliding the sliding door D to a position where the connecting member 4 and the connected member 5 face each other or rotating the transmission member 3. It can be carried out. That is, as shown in FIG. 5A, whether the sliding door D is slid even when the position between the connecting member 4 and the connected member 5 is shifted in the sliding direction Y of the sliding door D. When the transmission member 3 is rotated to move the connected member 5 to a position facing the connecting member 4, they are attracted to each other by a magnetic force, and the connection between the connecting member 4 and the connected member 5 is simplified. Can be done.

また、本実施形態の被連結部材５は、図６（ａ）に示されるように、嵌合凹部５ａを備え、連結部材４は、嵌合凹部５ａに嵌合する嵌合部を備えている。これにより、連結部材４と被連結部材５とが対向したときに、図１および図７に示されるように、嵌合部が嵌合凹部５ａに嵌合する。嵌合凹部５ａは、図５（ａ）、（ｂ）および図６（ａ）に示されるように、例えば引き戸Ｄ２がスライド方向Ｙに移動したときに、嵌合部（後述する連結部材４の吸着面４２。図７参照）のスライド方向Ｙの端部と当接する位置に壁部Ｗ１、Ｗ２を有している。このため、連結部材４と被連結部材５とが嵌合した後、引き戸Ｄがスライド方向Ｙに移動して、連結部材４と被連結部材５とがスライド方向Ｙで互いにずれるような力が加わっても、連結部材４と被連結部材５との間の連結が解除されることがない。なお、本実施形態では、嵌合凹部５ａは、被連結部材５に設けられ、嵌合部が連結部材４側に設けられているが、被連結部材５側に嵌合部を設け、連結部材４側に嵌合凹部を形成しても構わない。 Moreover, the to-be-connected member 5 of this embodiment is provided with the fitting recessed part 5a, and the connection member 4 is provided with the fitting part fitted to the fitting recessed part 5a, as FIG. 6 (a) shows. . Thereby, when the connection member 4 and the to-be-connected member 5 oppose, as shown in FIG. 1 and FIG. 7, a fitting part fits into the fitting recessed part 5a. As shown in FIGS. 5A, 5 B, and 6 A, for example, when the sliding door D 2 moves in the sliding direction Y, the fitting recess 5 a has a fitting portion (a connecting member 4 described later). Wall portions W1 and W2 are provided at positions where they come into contact with the end portions in the sliding direction Y of the suction surface 42 (see FIG. 7). For this reason, after the connecting member 4 and the connected member 5 are fitted, the sliding door D moves in the sliding direction Y, and a force is applied so that the connecting member 4 and the connected member 5 are displaced from each other in the sliding direction Y. However, the connection between the connecting member 4 and the connected member 5 is not released. In addition, in this embodiment, although the fitting recessed part 5a is provided in the to-be-connected member 5, and the fitting part is provided in the connecting member 4 side, a fitting part is provided in the to-be-connected member 5 side, and a connecting member A fitting recess may be formed on the 4 side.

本実施形態の被連結部材５は、より詳細に説明すると、図６（ａ）および（ｂ）に示されるように、基部５１と、歯付ベルト３のラック部３ａが係合する係合部５２ａを備えた係合部材５２とを備えている。基部５１は、略直方体状の部材から、一対の壁部Ｗ１、Ｗ２が、対向する引き戸に向かって突出し、壁部Ｗ１とＷ２との間に嵌合凹部５ａを形成している。基部５１には本実施形態では磁石Ｍが取り付けられ、連結部材４を磁力により吸着可能としている。なお、上述したように、連結部材４側に磁石を設ける場合などは、基部５１には磁性体または第２の磁石が設けられる。基部５１は、本実施形態では、図６（ａ）に示されるように、磁石Ｍ以外に、中央にネジ穴５ｂが形成され、ネジ穴５ｂの上部側に磁石Ｍが埋設されるが、ネジ穴５ｂや、磁石Ｍの埋設位置は、図示する位置に限定されるものではない。また、基部５１は、歯付ベルト３の幅に対応した溝部５ｃ（図７参照）を、基部５１と係合部材５２とが対向する対向面上に有しており、この溝部５ｃに歯付ベルト３が嵌まり込んで、歯付ベルト３の取り付けを容易にしている。 More specifically, the connected member 5 of the present embodiment is, as shown in FIGS. 6A and 6B, an engaging portion where the base portion 51 and the rack portion 3 a of the toothed belt 3 are engaged. And an engaging member 52 provided with 52a. In the base 51, a pair of wall portions W1 and W2 project from a substantially rectangular parallelepiped member toward the opposing sliding door, and a fitting recess 5a is formed between the wall portions W1 and W2. In this embodiment, a magnet M is attached to the base 51 so that the connecting member 4 can be attracted by a magnetic force. As described above, when a magnet is provided on the connecting member 4 side, the base 51 is provided with a magnetic body or a second magnet. In the present embodiment, as shown in FIG. 6A, the base 51 is formed with a screw hole 5b in the center other than the magnet M, and the magnet M embedded in the upper side of the screw hole 5b. The positions where the holes 5b and the magnets M are embedded are not limited to the illustrated positions. The base 51 has a groove 5c (see FIG. 7) corresponding to the width of the toothed belt 3 on the facing surface where the base 51 and the engaging member 52 face each other, and the groove 5c is toothed. The belt 3 is fitted to facilitate attachment of the toothed belt 3.

係合部材５２は、本実施形態では、図６（ａ）、（ｂ）および図７に示されるように、基部５１に接続される板状の部材であり、歯付ベルト３のラック部３ａに対応した形状の係合部５２ａが形成されている。本実施形態では、複数の係合部５２ａ（図６（ａ）および（ｂ）では、４つの係合部５２ａが示されている）を備え、隣接する係合部５２ａは、ラック部３ａ同士の長手方向の間隔に対応した間隔で設けられている。この係合部５２ａにラック部３ａが入り込むことにより、取付時にスライド方向Ｙにおける被連結部材５と歯付ベルト３との間の相対移動が防止される。 In this embodiment, the engaging member 52 is a plate-like member connected to the base 51 as shown in FIGS. 6A, 6B and 7, and the rack portion 3 a of the toothed belt 3. An engaging portion 52a having a shape corresponding to the above is formed. In the present embodiment, a plurality of engaging portions 52a (four engaging portions 52a are shown in FIGS. 6A and 6B), and the adjacent engaging portions 52a are connected to each other between the rack portions 3a. Are provided at intervals corresponding to the intervals in the longitudinal direction. When the rack portion 3a enters the engaging portion 52a, relative movement between the connected member 5 and the toothed belt 3 in the sliding direction Y is prevented during attachment.

基部５１に設けられたネジ穴５ｂは基部５１を貫通して設けられ、歯付ベルト３のラック部３ａと係合する係合部材５２にもネジ穴５ｄ（図６（ａ）および（ｂ）参照）が形成され、基部５１と係合部材５２により歯付ベルト３を挟み込んだ後、ネジ穴５ｂ、５ｄにネジをねじ込んで、基部５１と係合部材５２とを固定して、歯付ベルト３と被連結部材５とを固定することができる。このとき、係合部材５２が磁性体から形成されている場合、歯付ベルト３を基部５１との間で挟み込んだ状態で、基部５１の磁石Ｍに係合部材５２が吸着されるため、ネジを取り付けるときの作業性が向上する。この場合、磁石Ｍは、基部５１のうち、引き戸Ｄの厚さ方向Ｘにおける両側に磁力を及ぼすように構成される。 The screw hole 5b provided in the base 51 is provided through the base 51, and the engagement member 52 that engages with the rack 3a of the toothed belt 3 also has a screw hole 5d (FIGS. 6A and 6B). After the toothed belt 3 is sandwiched between the base 51 and the engaging member 52, screws are screwed into the screw holes 5b and 5d to fix the base 51 and the engaging member 52, and the toothed belt. 3 and the connected member 5 can be fixed. At this time, when the engaging member 52 is formed of a magnetic material, the engaging member 52 is attracted to the magnet M of the base 51 in a state where the toothed belt 3 is sandwiched between the base 51 and the screw. Workability when mounting is improved. In this case, the magnet M is configured to exert a magnetic force on both sides of the base 51 in the thickness direction X of the sliding door D.

なお、基部５１と係合部材５２との間の接続方法は、図示したものに限定されるものではない。例えば、基部５１と係合部材５２とを、ヒンジ部を介して接続して一体とし、歯付ベルト３を挟み込む際に、係合部材５２が基部５１に対して旋回して、歯付ベルト３を基部５１に取り付けた後に、係合部材５２を基部５１に対して歯付ベルト３を挟み込むように旋回させて、歯付ベルト３を挟み込んだ状態で、係合部材５２を基部５１に対して係合爪などで固定してもよい。 In addition, the connection method between the base 51 and the engaging member 52 is not limited to what is illustrated. For example, the base 51 and the engaging member 52 are connected and integrated through a hinge portion, and when the toothed belt 3 is sandwiched, the engaging member 52 pivots with respect to the base 51 to provide the toothed belt 3. Is attached to the base 51, and the engaging member 52 is swung with respect to the base 51 so as to sandwich the toothed belt 3. You may fix with an engaging nail | claw etc.

また、本実施形態では、歯付ベルト３は、図１、図６（ａ）および（ｂ）に示されるように、ループを形成しない２つの直線状のベルト部材３１、３２から構成されている。この場合、図６（ａ）および（ｂ）に示されるように、歯付ベルト３のベルト部材３１の一端に形成されているラック部３ａを、係合部材５２の係合部５２ａに挿入し、もう１つのベルト部材３２の一端に形成されているラック部３ａを、同様に係合部材５２の係合部５２ａに挿入して、基部５１と係合部材５２とでベルト部材３１、３２を挟み込み、２つのベルト部材３１、３２を被連結部材５の箇所で連結することができる。この利点としては、歯付ベルト３のループを形成する際に、現場においてループではない１本の十分な長さを有するベルトを、所望の引き戸Ｄの幅に応じた長さにカットして、ループではない１本のベルトからループ状の歯付ベルトに加工することができる点である。例えば、予めループ状の歯付ベルトを用意する場合には、引き戸Ｄのスライド方向Ｙにおける幅に応じた長さのループを形成するために、工場に発注をかけて製造するため、消費者から連動引き戸の注文があってから、実際に引き戸を取り付けるまでに、時間がかかってしまっていた。しかし、このように歯付ベルト３をカットして被連結部材５の部位でベルト部材３１、３２の端部を接続することにより、現場で簡単に長さ調節ができるため、すぐに引き戸Ｄを取り付けることが可能となった。また、このベルト部材３１、３２の端部の接続は、ベルト部材３１、３２との間の接続と、被連結部材５と歯付ベルト３との間の連結とを同時に行うことができるため、作業も非常に簡単である。なお、本実施形態では、２本の直線状のベルト部材３１、３２を接続しているが、１本の直線状のベルトの端部を被連結部材５の部位で接続してループを形成してもよい。 Moreover, in this embodiment, the toothed belt 3 is comprised from the two linear belt members 31 and 32 which do not form a loop, as FIG. 1, FIG. 6 (a) and (b) shows. . In this case, as shown in FIGS. 6A and 6B, the rack portion 3a formed at one end of the belt member 31 of the toothed belt 3 is inserted into the engaging portion 52a of the engaging member 52. Similarly, the rack portion 3 a formed at one end of the other belt member 32 is similarly inserted into the engaging portion 52 a of the engaging member 52, and the belt members 31 and 32 are connected by the base portion 51 and the engaging member 52. The two belt members 31 and 32 can be connected at the position of the connected member 5 by sandwiching. As an advantage of this, when forming a loop of the toothed belt 3, a belt having a sufficient length that is not a loop in the field is cut into a length corresponding to the width of the desired sliding door D, It is a point which can be processed into a loop-like toothed belt from one belt which is not a loop. For example, in the case of preparing a looped toothed belt in advance, in order to form a loop having a length corresponding to the width in the sliding direction Y of the sliding door D, it is manufactured by placing an order from the factory. It took some time to place the sliding doors after placing an order for the interlocking sliding doors. However, by cutting the toothed belt 3 and connecting the end portions of the belt members 31 and 32 at the site of the connected member 5, the length can be easily adjusted at the site. It became possible to install. Moreover, since the connection of the edge part of this belt member 31 and 32 can perform the connection between the belt members 31 and 32, and the connection between the to-be-connected member 5 and the toothed belt 3, simultaneously, The work is also very easy. In this embodiment, two linear belt members 31 and 32 are connected, but the end of one linear belt is connected at the portion of the connected member 5 to form a loop. May be.

また、本実施形態では、図７に示されるように、連結部材４は、引き戸Ｄ２、引き戸Ｄ３の上端面ＵＳに固定される固定部４１と、引き戸Ｄ２の上端面ＵＳに対して略垂直に延び、被連結部材と磁力により吸着しあう吸着面４２と、吸着面４２から引き戸Ｄ１側に向かって略垂直に延びる延設部４３とを備えている。固定部４１はネジ等の公知の固定手段により引き戸Ｄに取り付けられる。吸着面４２は被連結部材５と磁力により吸着される面であり、本実施形態では、嵌合凹部５ａに嵌合する嵌合部としても機能している。また、延設部４３は、上述したように、伝動部材３の回動による動作により、伝動部材３が上側に浮き上がってしまうため、延設部４３が伝動部材３の上方まで延びていることにより、伝動部材３の浮き上がりを防止することができる。 Moreover, in this embodiment, as FIG. 7 shows, the connection member 4 is substantially perpendicular | vertical with respect to the fixed part 41 fixed to the upper end surface US of the sliding door D2 and the sliding door D3, and the upper end surface US of the sliding door D2. An adsorption surface 42 that extends and adsorbs to the connected member by magnetic force, and an extending portion 43 that extends substantially perpendicularly from the adsorption surface 42 toward the sliding door D1 side are provided. The fixing portion 41 is attached to the sliding door D by a known fixing means such as a screw. The attracting surface 42 is a surface that is attracted to the coupled member 5 by a magnetic force, and also functions as a fitting portion that fits into the fitting recess 5a in the present embodiment. Further, as described above, since the transmission member 3 floats upward due to the rotation of the transmission member 3 as described above, the extension portion 43 extends to above the transmission member 3. The lifting of the transmission member 3 can be prevented.

また、本実施形態の変形例として、図８（ａ）〜（ｃ）に示されるように、被連結部材５の基部５１が、連結部材４（４ａ）の延設部４３が挿入される挿入部５３を備えていてもよい。挿入部５３は、図８（ａ）〜（ｃ）では、基部５１を貫通して形成された貫通孔として示されているが、延設部４３を挿入することができれば、貫通している必要はない。連結部材４と被連結部材５とが連結されるときに、図８（ｃ）に示されるように、挿入部５３に延設部４３が挿入される。これにより、連結部材４と被連結部材５との間の鉛直方向の移動が規制され、連結部材４と被連結部材５との間の離脱が防止される。この挿入部５３と延設部４３との間の係合は、特に、引き戸Ｄを閉鎖したときに、引き戸Ｄの端面（たとえば、図１における引き戸Ｄ２の右側の端面や、引き戸Ｄ３の左側の端面など）が壁などに勢いよく衝突した場合に役に立つ。すなわち、引き戸Ｄの閉鎖時に、引き戸Ｄの端面が壁などに勢いよく衝突した場合、引き戸Ｄと壁との衝突による衝撃や、引き戸Ｄが壁からはね返る際の衝撃（たとえば、引き戸Ｄの端面に引き戸Ｄの衝突時の衝撃を吸収する弾性クッションが設けられている場合など）や、その他、人が引き戸Ｄに衝突したときの衝撃などにより、連結部材４と被連結部材５との間に、離脱する方向の力が加わる場合がある。そのため、この変形例では、連結部材４と被連結部材５との間での、磁石による吸着力と、嵌合部と嵌合凹部５ａとの間のスライド方向での嵌合に加えて、鉛直方向の相対移動を規制している。これにより、引き戸Ｄへの衝撃時に、鉛直方向で連結部材４と被連結部材５との間に相対移動する力が加わっても、延設部４３が挿入部５３に挿入されることにより、挿入部５３の上下の壁部５３ａ、５３ｂにより、被連結部材５が連結部材４から離脱することが防止される。したがって、この変形例では、より強固に連結部材４と被連結部材５とを連結することが可能となり、引き戸Ｄの閉鎖時など、衝撃を受けたときに連結部材４と被連結部材５との間の離脱が確実に防止される。 Further, as a modification of the present embodiment, as shown in FIGS. 8A to 8C, the base 51 of the connected member 5 is inserted and the extended portion 43 of the connecting member 4 (4a) is inserted. The part 53 may be provided. The insertion portion 53 is shown as a through hole formed through the base portion 51 in FIGS. 8A to 8C, but needs to be penetrated if the extension portion 43 can be inserted. There is no. When the connecting member 4 and the connected member 5 are connected, the extending portion 43 is inserted into the insertion portion 53 as shown in FIG. Thereby, the vertical movement between the connecting member 4 and the connected member 5 is restricted, and the separation between the connecting member 4 and the connected member 5 is prevented. The engagement between the insertion portion 53 and the extended portion 43 is particularly the end surface of the sliding door D (for example, the right end surface of the sliding door D2 in FIG. 1 or the left side of the sliding door D3 when the sliding door D is closed). This is useful when the end face, etc.) collides with a wall. That is, when the end surface of the sliding door D collides with a wall or the like vigorously when the sliding door D is closed, an impact caused by the collision between the sliding door D and the wall or an impact when the sliding door D rebounds from the wall (for example, the end surface of the sliding door D). Between the connecting member 4 and the connected member 5 due to, for example, an impact when a person collides with the sliding door D, etc. A force in the direction of separation may be applied. Therefore, in this modification, in addition to the attractive force of the magnet between the connecting member 4 and the connected member 5 and the fitting in the sliding direction between the fitting portion and the fitting recess 5a, the vertical The relative movement of the direction is restricted. As a result, even when a force of relative movement is applied between the connecting member 4 and the connected member 5 in the vertical direction at the time of impact on the sliding door D, the extension portion 43 is inserted into the insertion portion 53, so that the insertion is performed. The upper and lower wall portions 53 a and 53 b of the portion 53 prevent the connected member 5 from being detached from the connecting member 4. Therefore, in this modified example, it becomes possible to connect the connecting member 4 and the connected member 5 more firmly, and when the impact is received such as when the sliding door D is closed, the connecting member 4 and the connected member 5 Separation in between is reliably prevented.

つぎに、本発明の連動引き戸装置の他の実施形態を説明する。以下の実施形態では、方向転換部材２ａ、２ｂ、伝動部材３、連結部材４、被連結部材５等、各実施形態を構成する要素については、第１の実施形態と同様のものを用いることができるため、説明は省略し、相違点を中心に説明する。また、以下の実施形態と、第１の実施形態で説明した事項とを組み合わせることが可能であり、その場合、上述した効果と同様の効果を奏することが可能である。 Next, another embodiment of the interlocking sliding door device of the present invention will be described.

However, the extension part 49 is not limited to the structure of the present embodiment, and may be any other shape as long as it extends beyond the height of the third connecting member 4c.

本実施形態では、連結部材４ａおよび第３の連結部材４ｃがスライド方向Ｙで一致する位置に移動したときに、連結部材４ａが第３の連結部材４ｃの上方に位置する。したがって、図１４に示したように、引き戸Ｄを閉鎖方向にスライドさせて、連結部材４ａと、第３の連結部材４ｃが近付くように移動したときに、連結部材４ａと第３の連結部材４ｃとが干渉しない。そのため、第１の実施形態および第２の実施形態と同様の効果に加えて、引き戸Ｄのスライド方向Ｙでの重なりＡを小さくすることができる。また、本実施形態では、被連結部材５および第３の被連結部材５０ｃが図１５に示されるように、上下方向にずれて位置しているため、引き戸Ｄ１１と引き戸Ｄ１２の間隔を狭くすることができる。 In the present embodiment, when the connecting member 4a and the third connecting member 4c move to a position where they coincide with each other in the sliding direction Y, the connecting member 4a is positioned above the third connecting member 4c. Therefore, as shown in FIG. 14, when the sliding door D is slid in the closing direction and moved so that the connecting member 4a and the third connecting member 4c approach each other, the connecting member 4a and the third connecting member 4c. Does not interfere with. Therefore, in addition to the effect similar to 1st Embodiment and 2nd Embodiment, the overlap A in the sliding direction Y of the sliding door D can be made small. Moreover, in this embodiment, since the to-be-connected member 5 and the 3rd to-be-connected member 50c are located in the up-down direction as shown in FIG. 15, the interval between the sliding door D11 and the sliding door D12 is reduced. Can do.

なお、連結部材４ａと第３の連結部材４ｃの形状が逆であってもよい。第４の連結部材４ｄおよび第５の連結部材４ｅは、それぞれ連結部材４ａおよび第３の連結部材４ｃと同様の構成とすることができる。また、第４の連結部材４ｄと第５の連結部材４ｅの形状を逆にしても構わない。 Note that the shapes of the connecting member 4a and the third connecting member 4c may be reversed. The 4th connection member 4d and the 5th connection member 4e can be set as the structure similar to the connection member 4a and the 3rd connection member 4c, respectively. Further, the shapes of the fourth connecting member 4d and the fifth connecting member 4e may be reversed.

＜第５の実施形態＞

It extends to intersect. In the present embodiment, the connecting member 4 a includes a fixed portion 41 and an extension portion 420 that extends obliquely from the fixed portion 41 toward the transmission member 3. The extension part 420 has an inclined plate-like inclined part 420a and a horizontal part 420b extending horizontally from the upper end of the inclined part 420a. Similarly, the third connecting member 4c has a fixed portion 41 and an extended portion 420 including an inclined portion 420a and a horizontal portion 420b. In the present embodiment, the connecting member 4a and the third connecting member 4c include a magnet (not shown) provided on the upper end side of the connected member 5 and the third connected member 50c, and the horizontal portions thereof. 420b is connected by being adsorbed.

また、本実施形態では、交差した連結部材４ａおよび第３の連結部材４ｃが、引き戸Ｄの厚さ方向Ｘに切断した断面が図１７に示されるように、略Ｘ字状になるように構成されているが、連結部材４ａおよび第３の連結部材４ｃが、連結部材が取り付けられる引き戸Ｄから伝動部材３または第２伝動部材３３に向かって延びる過程で交差するように構成されていれば、交差した連結部材４ａおよび第３の連結部材４ｃが略Ｘ字状となる必要はなく、他の形状であってもよい。 Further, in the present embodiment, the intersecting connecting member 4a and the third connecting member 4c are configured such that the cross section cut in the thickness direction X of the sliding door D is substantially X-shaped as shown in FIG. However, if the connecting member 4a and the third connecting member 4c are configured to intersect in the process of extending from the sliding door D to which the connecting member is attached toward the transmission member 3 or the second transmission member 33, The intersecting connecting member 4a and third connecting member 4c do not have to be substantially X-shaped, and may have other shapes.

本実施形態では、図１８に示されるように、連結部材４ａの延長部４２０のうち、第３の連結部材４ｃの延長部４２０と交差する部位において、引き戸閉鎖方向側に切欠部４３０を有している。また、第３の連結部材４ｃの延長部４２０のうち、連結部材４ａの延長部４２０と交差する部位において、引き戸開放方向側に切欠部４３０を有している。この構成により、連結部材４ａおよび第３の連結部材４ｃがスライド方向Ｙで一致する位置に移動したときに、連結部材４ａの切欠部４３０に第３の連結部材４ｃの切欠部４３０が入り込むように構成されている。そのため、第１の実施形態および第２の実施形態と同様の効果に加えて、引き戸Ｄのスライド方向Ｙでの重なりＡを小さくすることができる。 In this embodiment, as shown in FIG. 18, a portion of the extension portion 420 of the connection member 4 a that intersects the extension portion 420 of the third connection member 4 c has a notch 430 on the sliding door closing direction side. ing. Moreover, in the site | part which cross | intersects the extension part 420 of the connection member 4a among the extension parts 420 of the 3rd connection member 4c, it has the notch part 430 in the sliding door open | release direction side. With this configuration, when the connecting member 4a and the third connecting member 4c move to a position where they coincide with each other in the sliding direction Y, the notched portion 430 of the third connecting member 4c enters the notched portion 430 of the connecting member 4a. It is configured. Therefore, in addition to the effect similar to 1st Embodiment and 2nd Embodiment, the overlap A in the sliding direction Y of the sliding door D can be made small.

なお、連結部材４ａの切欠部４３０の最奥部４３０ａと第３の連結部材４ｃの切欠部４３０の最奥部４３０ａとは、係合するように構成してもよいし、たとえば、切欠部４３０のスライド方向Ｙの長さを長くすることなどにより、引き戸Ｄが閉鎖したときに、連結部材４ａの切欠部４３０の最奥部４３０ａと第３の連結部材４ｃの切欠部４３０の最奥部４３０ａとが接触しないように構成することもできる。連結部材４ａの切欠部４３０の最奥部４３０ａと第３の連結部材４ｃの切欠部４３０の最奥部４３０ａとが接触しないようにすることにより、連結部材４ａおよび第３の連結部材４ｃが衝突せずに負荷が加わらないため、製品の寿命を延ばすことができ、連結部材４ａと被連結部材５との間および第３の連結部材４ｃと第３の被連結部材５０ｃとの間の連結を確実に維持することができる。 The innermost part 430a of the notch 430 of the connecting member 4a and the innermost part 430a of the notch 430 of the third connecting member 4c may be configured to be engaged, for example, the notch 430. When the sliding door D is closed by increasing the length of the sliding direction Y, the innermost part 430a of the notch part 430 of the connecting member 4a and the innermost part 430a of the notch part 430 of the third connecting member 4c are used. It can also be configured not to come into contact with. By preventing the innermost part 430a of the notch 430 of the connecting member 4a from contacting the innermost part 430a of the notch 430 of the third connecting member 4c, the connecting member 4a and the third connecting member 4c collide. Therefore, the life of the product can be extended, and the connection between the connecting member 4a and the connected member 5 and the connection between the third connecting member 4c and the third connected member 50c can be performed. It can be reliably maintained.

なお、切欠部４３０の形状は、本実施形態では、Ｖ字状の谷状に切り欠かれた切欠部として示されているが、スリット状の溝など、他の形状であっても構わない。また、第４の連結部材４ｄおよび第５の連結部材４ｅは、それぞれ連結部材４ａおよび第３の連結部材４ｃと同様の構成とすることができる。 In addition, although the shape of the notch part 430 is shown as a notch part notched by the V-shaped valley shape in this embodiment, other shapes, such as a slit-shaped groove | channel, may be sufficient. Moreover, the 4th connection member 4d and the 5th connection member 4e can be set as the structure similar to the connection member 4a and the 3rd connection member 4c, respectively.
