Description

本発明は、扉体を回動および開口部横幅方向への移動により開閉動作させるようにした折戸やバランスドア等の開閉扉に関し、特に両開き式の折戸に関するものである。   The present invention relates to an opening / closing door such as a folding door or a balance door that is opened and closed by turning and moving the door body in the lateral width direction of the opening, and particularly relates to a double-folding type folding door.

従来、この種の発明としては、例えば、特許文献１〜４に記載されたもののように、戸先側の扉体と、該戸先側の扉体に隣り合って回動自在に接続された戸尻側の扉体とからなる開閉体により構成された折戸がある。   Conventionally, as this kind of invention, for example, as described in Patent Documents 1 to 4, the door body on the door-end side and the door body on the door-end side are adjacently connected to be rotatable. There is a folding door composed of an opening / closing body composed of a door body on the door bottom side.

より詳細に説明すれば、例えば図１２に示すように、開閉扉１は、前記開閉体１１０と、該開閉体１１０により開閉させる開口部を囲む枠体１２０と、開閉体１１０をその開閉動作に伴って横幅方向（図１２における左右方向）へ案内するガイド機構１３０と、開閉体１１０を前記枠体１２０に対し回動可能に支持する基軸部１４０とを具備している。   More specifically, for example, as shown in FIG. 12, the opening / closing door 1 includes an opening / closing body 110, a frame body 120 that surrounds an opening that is opened / closed by the opening / closing body 110, and the opening / closing body 110. Accordingly, a guide mechanism 130 that guides in the lateral width direction (left and right direction in FIG. 12) and a base shaft portion 140 that rotatably supports the opening / closing body 110 with respect to the frame body 120 are provided.

戸先側の扉体１１１は、略縦長矩形板状に構成され、表部及び／又は裏部における戸先側に、開閉操作のための取手部１１１ａを固定し、その逆側に具備されたヒンジ機構１１３を介して、戸尻側の扉体１１２に対し、接続されている。
そして、この戸先側の扉体１１１は、その横幅方向の中央近傍の部分が、ガイド機構１３０によって回動自在かつ横幅方向へスライド自在に吊るされている。したがって、戸先側の扉体１１１は、開閉動作の際、ガイド機構１３０に沿って横幅方向へ移動しながら回動する。 The door body 111 on the door tip side is configured in a substantially vertically long rectangular plate shape, and a handle portion 111a for opening and closing operation is fixed to the door tip side in the front portion and / or the back portion, and is provided on the opposite side. The door mechanism 112 is connected to the door body 112 on the door bottom side via the hinge mechanism 113.
The door body 111 on the door end side is suspended by a guide mechanism 130 so as to be rotatable and slidable in the lateral width direction in the vicinity of the center in the lateral width direction. Accordingly, the door body 111 on the door end side rotates while moving in the lateral direction along the guide mechanism 130 during the opening / closing operation.

また、戸尻側の扉体１１２は、戸先側の扉体１１１よりも横幅方向寸法の小さい略縦長矩形板状に構成され、その横幅方向においてヒンジ機構１１３と逆側の端部が、基軸部１４０によって回動可能に支持されている。   Moreover, the door body 112 on the door bottom side is configured in a substantially vertically long rectangular plate shape having a smaller width direction dimension than the door body 111 on the door end side, and an end portion on the opposite side to the hinge mechanism 113 in the width direction is a base shaft. The portion 140 is rotatably supported.

また、図１３に示すように、ヒンジ機構１１３は、横断面略扇方状の歯車部材１１３ａを互いに噛み合うように２つ配置し、これら歯車部材１１３ａの軸心部Ｒを、その各々が回動自在となるようにブラケット１１３ｂにより軸支することで構成されている。
このヒンジ機構１１３によれば、戸先側の扉体１１１における一方向への回動と、戸尻側の扉体１１２における他方向への回動とが連動するため、その開閉動作をスムーズにすることができる。 Further, as shown in FIG. 13, the hinge mechanism 113 is arranged so that two gear members 113a having a substantially fan-shaped cross section are engaged with each other, and the shaft center portion R of each of the gear members 113a is rotated. It is configured by being pivotally supported by a bracket 113b so as to be free.
According to this hinge mechanism 113, since the rotation in one direction in the door body 111 on the door end side and the rotation in the other direction in the door body 112 on the door bottom side are interlocked, the opening / closing operation can be smoothly performed. can do.

この際、戸尻側の扉体１１２の横幅方向の寸法Ｂ’（前記基軸部１４０の回動中心Ｐから、前記戸尻側の扉体１１２に取り付けられた歯車部材１１３ａの軸心部Ｒまでの長さ）は、戸先側の扉体１１１の横幅方向寸法（前記戸先側の扉体１１１に取り付けられた歯車部材１１３ａの軸心部Ｒから、前記戸先側の扉体１１１の戸先部分１１１ｂとの境界Ｓまでの長さ）の１／２に設定されており、開閉体１１０の横幅方向の中心線Ｑのどちら側にも、扉をほぼ全開することができるようになっている（図１３参照）。   At this time, the dimension B ′ in the lateral width direction of the door body 112 on the door butt side (from the rotation center P of the base shaft portion 140 to the shaft center portion R of the gear member 113a attached to the door body 112 on the door butt side. The length of the door body 111 in the width direction (from the axial center portion R of the gear member 113a attached to the door body 111 on the door edge side). The length up to the boundary S with the tip portion 111b) is set to 1/2, and the door can be almost fully opened on either side of the center line Q in the width direction of the opening / closing body 110. (See FIG. 13).

ここで、例えば車いすを使用する障害者などにとっては、引いて開けるより、押して開ける方がより簡単に扉を開けることができるため、通常、戸先側の扉体１１１を押して扉を開けている。
しかしながら、この場合、戸先側の扉体１１１における回動軸部１３１よりも戸尻側の部分と、戸尻側の扉体１１２とが使用者側に出っ張るため、途中で車いすにあたってしまい、扉を全開することが難しい、というデメリットがあった。 Here, for the handicapped person who uses a wheelchair, for example, the door can be opened more easily by pushing and opening than by pulling and opening, so the door is usually opened by pushing the door body 111 on the door side. .
However, in this case, since the door butt side portion of the door shaft 111 of the door end side and the door butt side door body 112 protrude to the user side than the pivot shaft portion 131, the wheelchair will be hit in the middle of the door. There was a demerit that it was difficult to fully open.

また、健常者が扉を使用したときに、使用条件によっては、扉を過剰な勢いで開けすぎて、扉が全開した場合に、戸先側の扉体１１１の戸先部分が、壁側まで勢いあまって持っていかれて、壁や扉（又は扉の取手部分）を傷つけてしまう可能性を想定できるケースもある。これに対しては、図１４に示すように、床付け戸当り２１０を設けて、戸先側の扉体１１１の戸先部分近傍が、それ以上、壁側に撓まないようにすることが考えられる。   In addition, when a healthy person uses the door, depending on the use conditions, if the door is opened with excessive momentum and the door is fully opened, the door tip portion of the door body 111 on the door tip side extends to the wall side. There are cases where it is possible to assume the possibility that the wall or door (or the handle part of the door) may be damaged due to momentum. For this, as shown in FIG. 14, a floor-mounted door stop 210 is provided so that the vicinity of the door tip portion of the door body 111 on the door tip side is not further bent toward the wall side. Conceivable.

しかしながら、この場合、例えば図１４に示す側に扉を開けた際には、扉を全開することができるが、逆側に扉を開けた際には、図１５に示すように、戸尻側の扉体１１２が先に戸当り２１０に当たってしまい、完全には全開することができないというデメリットがあった。また、戸当り２１０を両側にそれぞれ（一対）設けた際には、どちら側に扉を開いても、完全には扉を全開することができないというデメリットがあった。（図示省略）   However, in this case, for example, when the door is opened on the side shown in FIG. 14, the door can be fully opened. However, when the door is opened on the opposite side, as shown in FIG. The door body 112 hits the door stop 210 first, and there is a demerit that it cannot be fully opened. Further, when the door stop 210 is provided on each side (a pair), there is a demerit that the door cannot be fully opened regardless of which side the door is opened. (Not shown)

本発明は、上記事情に鑑みてなされたものであり、その課題とするところは、車いすなどの障害者にとっても、扉をより簡単に全開することができる両開き式折戸を提供することである。   This invention is made | formed in view of the said situation, The place made into the subject is providing the double-folding type folding door which can open a door more easily also for persons with disabilities, such as a wheelchair.

また、床付け戸当りを設けた場合にも、扉をどちら側にも全開することができる両開き式折戸を提供することである。   Another object of the present invention is to provide a double-folding type folding door that can be fully opened on either side even when a floor-mounted door is provided.

上記課題を解決するために、第一の発明は、戸先側の扉体１１１と、該戸先側の扉体１１１に隣り合って回動自在に接続された戸尻側の扉体１１２とを備えた両開き式折戸において、前記戸尻側の扉体１１２の横幅方向の寸法が、前記戸先側の扉体１１１の横幅方向の寸法の１／２よりも短いことを特徴としている。   In order to solve the above-mentioned problem, the first invention includes a door body 111 on the door end side, and a door body 112 on the door bottom side that is rotatably connected adjacent to the door body 111 on the door front side. In the double-folding type folding door provided with the door, the dimension in the width direction of the door body 112 on the door bottom side is shorter than ½ of the dimension in the width direction of the door body 111 on the door end side.

このようになっている本発明は、従来の戸尻側の扉体１１２の横幅方向の寸法が戸先側の扉体１１１の横幅方向の寸法の１／２である両開き式折戸では戸先側の扉体１１１の横幅方向の中央近傍に支持されていた回動軸部１３１が、戸先側の扉体１１１の中央よりも戸尻側に寄った位置において戸先側の扉体１１１の開閉時の支点となる。このため、戸先側の扉体１１１において、前記支点である回動軸部１３１から戸先側の部分の横幅方向の長さＡの方が、前記回動軸部１３１から戸尻側の部分の横幅方向の長さＢよりも長くなるので、戸先側の扉体１１１を軽く押すだけで、より簡単に扉を開くことができる。また、戸先側の扉体１１１を押した場合に手前側に張り出してくる戸先側の扉体１１１及び戸尻側の扉体１１２の長さＢが短いので、車いすなどの障害者にとって、前記扉体１１１や扉体１１２が車いすにあたってしまい、扉を全開することが難しいというデメリットも軽減することができる。   In the present invention thus configured, in the case of a double-folding type folding door in which the dimension in the width direction of the door body 112 on the door end side on the conventional side is ½ of the dimension in the width direction of the door body 111 on the door tip side, the door side Opening and closing of the door body 111 on the door-end side at a position where the pivot shaft 131 supported in the vicinity of the center in the width direction of the door body 111 is closer to the door bottom side than the center of the door body 111 on the door-end side. It becomes a fulcrum of time. For this reason, in the door body 111 on the door end side, the length A in the lateral width direction of the portion on the door end side from the rotation shaft portion 131 that is the fulcrum is a portion on the door bottom side from the rotation shaft portion 131. Thus, the door can be opened more easily by simply pressing the door body 111 on the door end side. Moreover, since the length B of the door body 111 on the front side and the door body 112 on the door edge side that protrudes toward the front side when the door body 111 on the door side is pushed is short, for a disabled person such as a wheelchair, The demerit that it is difficult to fully open the door due to the door body 111 or the door body 112 hitting a wheelchair can be reduced.

また、第二の発明は、両開き式折戸を全開した時に前記戸先側の扉体１１１が当接する位置の床に、前記両開き式折戸をどちら側に開いた場合にも前記戸先側の扉体１１１とそれぞれ当接するように一対の床付け戸当り２１０，２１０が取り付けられており、前記戸尻側の扉体１１２の横幅方向の寸法Ｂは、前記両開き式折戸をどちら側に開いた場合にも、前記戸尻側の扉体１１２が前記床付け戸当り２１０，２１０に当接することがない長さに設定されていることを特徴としている。   Further, the second invention is such that when the double-folding folding door is fully opened, the door-side door is opened on either side when the double-folding folding door is opened on either side of the floor at the position where the door-side door body 111 abuts. A pair of floor-mounted doors 210 and 210 are attached so as to come into contact with the body 111, respectively, and the dimension B in the lateral width direction of the door body 112 on the door bottom side is when the double folding door is opened on either side. In addition, the door body 112 on the door bottom side is set to a length that does not contact the floor-mounted doors 210 and 210.

この発明によれば、床付け戸当りを設ける必要がある場合であっても、前記両開き式折戸をどちら側に開いた場合にも、扉を完全に全開することができる。   According to the present invention, even when it is necessary to provide a flooring door contact, the door can be fully opened regardless of which side the folding door is opened.

さらに、第三の発明は、前記戸尻側の扉体の横幅方向の寸法をＢ、前記戸先側の扉体の横幅方向の寸法をＡ＋Ｂ、扉を全開した場合の、前記戸先側の扉体１１１の戸先部分１１１ｂとの境界Ｓから戸尻側方向への前記床付け戸当り２１０の戸先側端部までの長さをα、戸先側の扉体１１１と戸尻側の扉体１１２との接続部分の各扉体における横幅方向の長さ（すなわち、歯車部材１１３ａの軸心部Ｒから、閉塞部材１１４の円弧状先端部分までの長さ）をβ、扉を全開した場合の、床付け戸当り２１０の戸先側端部から戸尻側端部までの長さをγとした場合に、
Ａ−Ｂ＞α＋β＋γ
という関係式が成り立つことを特徴とする。 Further, the third aspect of the invention is that the dimension in the width direction of the door body on the door bottom side is B, the dimension in the width direction of the door body on the door tip side is A + B, The length from the boundary S between the door body 111 and the door edge portion 111b to the door edge side end of the floor-mounted door stop 210 in the door edge side direction is α, and the door edge side door body 111 and the door edge side The length in the width direction of each door body at the connection portion with the door body 112 (that is, the length from the axial center portion R of the gear member 113a to the arcuate tip portion of the closing member 114) is β, and the door is fully opened. In this case, when the length from the door end side end to the door butt side end of 210 per flooring door is γ,
A-B> α + β + γ
It is characterized by the following relational expression.

この発明によれば、床付け戸当り２１０の大きさと取付位置に応じて、戸先側の扉体１１１と戸尻側の扉体１１２の横幅方向の寸法を設定するか、または、戸先側の扉体１１１と戸尻側の扉体１１２の横幅方向の寸法に応じて、床付け戸当り２１０の大きさと取付位置とを調整すれば、どの規格の床付け戸当りを使用したとしても、確実に扉を全開することができる。   According to the present invention, according to the size of the flooring door 210 and the mounting position, the dimensions of the width direction of the door body 111 on the door end side and the door body 112 on the door bottom side are set, or the door side If the size and mounting position of the floor door 210 are adjusted according to the widthwise dimensions of the door body 111 and the door body 112 on the door butt side, no matter which standard floor door is used, The door can be fully opened without fail.

Each roller 132 is disposed so as to roll in the lateral width direction of the upper frame member 121, and is rotatably supported on the upper end side of the rotation shaft portion 131 via a support bracket 134.
The rail member 133 is a member having a substantially L-shaped cross section that is fixed in the lateral width direction of the upper frame member 121, and on which the rollers 132 are movably mounted.

基軸部１４０は、開閉体１１０における戸尻側の扉体１１２の上端側を回動自在に支持する枢支部材１４１と、同扉体１１２の下端側を支持しながら扉体１１２を閉鎖方向へ付勢する付勢機構１４２とを具備してなる。   The base shaft section 140 pivotally supports the upper end side of the door body 112 on the door butt side of the opening / closing body 110 and the door body 112 in the closing direction while supporting the lower end side of the door body 112. And an urging mechanism 142 for urging.

また、図２に示すように、ヒンジ機構１１３は、横断面略扇方状の歯車部材１１３ａを互いに噛み合うように２つ配置し、これら歯車部材１１３ａの軸心部Ｒを、その各々が回動自在となるようにブラケット１１３ｂにより軸支することで構成されている。
このヒンジ機構１１３によれば、戸先側の扉体１１１における一方向への回動と、戸尻側の扉体１１２における他方向への回動とが連動するため、その開閉動作をスムーズにすることができる。 In addition, as shown in FIG. 2, the hinge mechanism 113 is arranged so that two gear members 113a having a substantially fan-shaped cross section are engaged with each other, and the shaft center portion R of each of the gear members 113a is rotated. It is configured by being pivotally supported by a bracket 113b so as to be free.
According to this hinge mechanism 113, since the rotation in one direction in the door body 111 on the door end side and the rotation in the other direction in the door body 112 on the door bottom side are interlocked, the opening / closing operation can be smoothly performed. can do.

なお、上記ヒンジ機構１１３及び両扉体１１１，１１２間の隙間は、ゴム等の弾性材料を断面略中空状に加工してなる閉塞部材１１４，１１４により覆われている。そのため、ヒンジ機構１１３や、両扉体１１１，１１２間の隙間に、手や物等が挟まれて大きなダメージを与えてしまうことを防ぐことができる。   The gap between the hinge mechanism 113 and the door bodies 111 and 112 is covered with closing members 114 and 114 formed by processing an elastic material such as rubber into a substantially hollow cross section. Therefore, it is possible to prevent a hand, an object, or the like from being sandwiched between the hinge mechanism 113 and the gap between the door bodies 111 and 112 and causing great damage.

ここで、図１及び図２に示すように、回動軸部１３１の軸心と基軸部１４０の軸心とは、全閉状態における開閉体１１０の厚さ方向において、該開閉体１１０の全閉状態から全開状態まで常に略同一位置である。
また、回動軸部１３１の軸心から戸先側の扉体１１１に取り付けられた歯車部材１１３ａの軸心部Ｒまでの長さと、基軸部１４０の回動中心Ｐから戸尻側の扉体１１２に取り付けられた歯車部材１１３ａの軸心部Ｒまでの長さとは、等しい（図２の寸法Ｂ）。
この、基軸部１４０の回動中心Ｐから戸尻側の扉体１１２に取り付けられた歯車部材１１３ａの軸心部Ｒまでの長さ、すなわち、戸尻側の扉体１１２の横幅方向の寸法Ｂは、戸先側の扉体１１１の横幅方向の寸法「Ａ＋Ｂ」（前記戸先側の扉体１１１に取り付けられた歯車部材１１３ａの軸心部Ｒから、前記戸先側の扉体１１１の戸先部分１１１ｂとの境界Ｓまでの長さ）の１／２よりも短く設定されている。 Here, as shown in FIGS. 1 and 2, the shaft center of the rotation shaft portion 131 and the shaft center of the base shaft portion 140 are all in the thickness direction of the opening / closing body 110 in the fully closed state. From the closed state to the fully open state, the position is always substantially the same.
Further, the length from the axial center of the rotating shaft part 131 to the axial center part R of the gear member 113a attached to the door body 111 on the door end side, and the door body on the door bottom side from the rotational center P of the base shaft part 140. The length to the axial center part R of the gear member 113a attached to 112 is equal (dimension B in FIG. 2).
The length from the rotation center P of the base shaft portion 140 to the shaft center portion R of the gear member 113a attached to the door body 112 on the door butt side, that is, the dimension B in the lateral width direction of the door body 112 on the door butt side. Is the dimension “A + B” of the door body 111 on the door end side (from the axial center R of the gear member 113a attached to the door body 111 on the door end side, the door of the door body 111 on the door end side It is set to be shorter than ½ of the length to the boundary S with the tip portion 111b.

そして、前述のとおり、戸先側の扉体１１１は、その横幅方向の中央よりも少しだけ戸尻側の扉体１１２に近寄った部分が、ガイド機構１３０によって回動自在かつ横幅方向へスライド自在に吊るされており、戸先側の扉体１１１上端部の横幅方向の中央よりも少しだけ戸尻側の扉体１１２に近寄った部分に支持された回動軸部１３１が、戸先側の扉体１１１の開閉時の支点となる。   As described above, the door body 111 on the door end side can be rotated by the guide mechanism 130 and slidable in the lateral width direction by a portion close to the door body 112 on the door bottom side slightly from the center in the lateral width direction. The pivot shaft 131 supported by the portion close to the door body 112 on the door butt side slightly from the center in the lateral width direction of the upper end portion of the door body 111 on the door tip side is It becomes a fulcrum when the door body 111 is opened and closed.

その結果、戸先側の扉体１１１において、前記支点である回動軸部１３１から戸先側の部分の横幅方向の長さＡの方が、前記回動軸部１３１から戸尻側の部分の横幅方向の長さＢよりも長くなるので、戸先側の扉体１１１の取手１１１ａを軽く押すだけで、より簡単に扉を開くことができる。また、戸先側の扉体１１１を押した場合に手前側に張り出してくる戸先側の扉体１１１及び戸尻側の扉体１１２の長さＢが短いので、車いすなどの障害者にとって、前記扉体１１１や扉体１１２が車いすにあたってしまい、扉を全開することが難しいというデメリットも軽減することができるのである。   As a result, in the door body 111 on the door end side, the length A in the width direction of the portion on the door end side from the rotation shaft portion 131 that is the fulcrum is a portion on the door bottom side from the rotation shaft portion 131. Therefore, the door can be opened more simply by lightly pressing the handle 111a of the door body 111 on the door end side. Moreover, since the length B of the door body 111 on the front side and the door body 112 on the door edge side that protrudes toward the front side when the door body 111 on the door side is pushed is short, for a disabled person such as a wheelchair, The demerit that it is difficult to fully open the door due to the door body 111 or the door body 112 hitting a wheelchair can be reduced.

また、健常者が扉を使用したときに、使用条件によっては、扉を過剰な勢いで開けすぎて、扉が全開した場合に、戸先側の扉体１１１の戸先部分が、壁側まで勢いあまって持っていかれて、壁や扉（又は扉の取手部分）を傷つけてしまうおそれがあるため、床や壁、又は、扉に戸当りを設けてこれを回避するのが一般的である。
この際、納まりの都合上や、壁や扉に戸当りを設ける場合には、該壁や扉を衝撃に耐えるように強化しなければならなくなる関係上、床付け戸当りが必要な場合がある。また、壁や扉に戸当りを設けた場合には、全開した場合に、やはり勢いあまって扉が全開位置よりも壁側まで持っていかれるおそれがあるため、確実に全開位置で止めるためには、床付け戸当りが望ましい。
また、扉の上部を止めることも効果的であるが、扉体の撓みによりぐらつきやすい扉の下側を止めることの方がより効果的であるため、床付け戸当りが望ましい。
なお、床付け戸当りの形状としては、平面視略円形、楕円形、矩形等、様々なものが知られており、どのような形状のものであっても構わない。 In addition, when a healthy person uses the door, depending on the use conditions, if the door is opened with excessive momentum and the door is fully opened, the door tip portion of the door body 111 on the door tip side extends to the wall side. Since there is a possibility that the wall or door (or the handle part of the door) may be damaged due to momentum, it is common to avoid this by providing a door stop on the floor, wall, or door.
At this time, if the door or door is provided on a wall or door, it may be necessary to reinforce the wall or door to withstand impacts. . In addition, when the door is provided on the wall or door, if the door is fully opened, there is a risk that the door will be moved to the wall side rather than the fully open position. A floor-to-door door is desirable.
Moreover, although it is effective to stop the upper part of a door, since it is more effective to stop the lower side of a door which is easy to wobble due to the bending of a door body, a flooring door contact is desirable.
In addition, as a shape per flooring door, various things, such as a planar view substantially circular shape, an ellipse, and a rectangle, are known, What kind of shape may be sufficient.

図６及び図７は、床付け戸当り２１０を、扉をどちら側に全開した場合にも、それぞれ戸先側の扉体１１１に当接するように両側に一対設けた場合の、一実施例を示す図である。   FIGS. 6 and 7 show an embodiment in which a pair of floor-mounted doors 210 are provided on both sides so as to come into contact with the door body 111 on the door end side when the door is fully opened on either side. FIG.

図６及び図７の実施例では、戸当り２１０の最も太い部分の直径γが４５ｍｍである。ここで、前記γとは、戸当り２１０の平面視形状が真円形でない場合のことも考慮すると、扉を全閉した場合の開閉体１１０の厚さ方向の寸法、すなわち、扉を全開した場合の戸当り２１０の戸先側端部から戸尻側端部までの長さのことである。そして、扉を全開した場合に、戸先側の扉体１１１の戸先側先端部分（戸先部分近傍）が戸当り２１０に当接するように、床付け戸当り２１０が設置されている。ここで、具体的には、図６に示すように、扉を全開した場合の、前記戸先側の扉体１１１の戸先部分１１１ｂとの境界Ｓから、戸尻側方向への戸当り２１０の戸先側端部までの長さαが２ｍｍの位置であって、前記戸先側の扉体１１１に当接する位置に、戸当り２１０が取り付けられている。また、戸先側の扉体１１１と戸尻側の扉体１１２との接続部分の各扉体における横幅方向の長さ、すなわち、歯車部材１１３ａの軸心部Ｒから、閉塞部材１１４の先端部分（円弧状先端部分）までの長さβは３０ｍｍであるとする。   6 and 7, the diameter γ of the thickest part of the door stop 210 is 45 mm. Here, γ is a dimension in the thickness direction of the opening / closing body 110 when the door is fully closed, that is, when the door is not fully circular in plan view, that is, when the door is fully opened. It is the length from the door end side end of the door stop 210 to the door bottom side end. Then, when the door is fully opened, the flooring door stop 210 is installed such that the door end side tip portion (the vicinity of the door end portion) of the door end side door body 111 abuts against the door stop 210. Specifically, as shown in FIG. 6, when the door is fully opened, the door stop 210 in the door butt side direction from the boundary S with the door tip portion 111 b of the door body 111 on the door tip side. The door stop 210 is attached at a position where the length α up to the door end side of the door is 2 mm and abuts on the door body 111 on the door end side. Further, the length in the width direction of each door body at the connection portion between the door body 111 on the door end side and the door body 112 on the door bottom side, that is, from the axial center portion R of the gear member 113a, the distal end portion of the closing member 114 The length β up to (the arcuate tip) is assumed to be 30 mm.

また、戸尻側の扉体１１２の横幅方向の寸法Ｂ（前記基軸部１４０の回動中心Ｐから、前記戸尻側の扉体１１２に取り付けられた歯車部材１１３ａの軸心部Ｒまでの長さ）は、戸先側の扉体１１１の横幅方向の寸法「Ａ＋Ｂ」の１／２よりも４５ｍｍ短く設定されている。よって、戸先側の扉体１１１における、該戸先側の扉体１１１上端部の横幅方向の中央よりも少しだけ戸尻側の扉体１１２に近寄った部分に支持された回動軸部１３１から戸先部分１１１ｂとの境界Ｓまでの長さＡは、前記戸先側の扉体１１１の横幅方向の寸法「Ａ＋Ｂ」の１／２よりも４５ｍｍ長く設定されている。   In addition, the dimension B in the lateral width direction of the door body 112 on the door butt side (the length from the rotation center P of the base shaft part 140 to the shaft center part R of the gear member 113a attached to the door body 112 on the door butt side) Is set to be 45 mm shorter than 1/2 of the dimension “A + B” of the door body 111 on the door end side. Therefore, in the door body 111 on the door end side, the rotation shaft portion 131 supported by the portion slightly closer to the door body 112 on the door bottom side than the center in the width direction of the upper end portion of the door body 111 on the door end side. The length A from the door S to the boundary S with the door end portion 111b is set to be 45 mm longer than ½ of the dimension “A + B” in the horizontal width direction of the door body 111 on the door end side.

このとき、扉を全開した場合に、戸尻側の扉体１１２が戸当り２１０に当たらないようにするためには、前記戸先側の扉体１１１の戸先側の部分の横幅方向の寸法Ａと、前記戸先側の扉体１１１の戸尻側の部分の横幅方向の寸法（＝前記戸尻側の扉体１１２の横幅方向の寸法）Ｂとの差は、前記戸先側の扉体１１１の戸先部分１１１ｂとの境界Ｓから、戸尻側方向への戸当り２１０の円周部分端部までの長さαと、前記床付け戸当り２１０の直径γと、前記戸先側の扉体１１１と戸尻側の扉体１１２との接続部分の各扉体における横幅方向の長さβとを足した値よりも、大きくなければならない（図６及び図７参照）。すなわち、「Ａ−Ｂ」を「α＋β＋γ」より大きく設定しておかなければ、全開しようとした場合に、戸尻側の扉体１１２が戸当り２１０に当たってしまい、完全に全開することができなくなってしまうため、「Ａ−Ｂ ＞ α＋β＋γ」の関係式が成り立つように設定しておく必要がある。   At this time, in order to prevent the door body 112 on the door bottom side from hitting the door stop 210 when the door is fully opened, the dimension in the width direction of the door side portion of the door body 111 on the door tip side The difference between A and the width dimension of the door-side portion of the door-side door body 111 (= the width-direction dimension of the door-side door body 112) B is the door-side door. The length α from the boundary S with the door tip portion 111b of the body 111 to the end of the circumferential portion of the door stop 210 in the door bottom side direction, the diameter γ of the floor mounting door 210, and the door tip side It must be larger than the value obtained by adding the length β in the lateral width direction of each door body at the connection portion between the door body 111 and the door body 112 on the door bottom side (see FIGS. 6 and 7). That is, if “A−B” is not set to be larger than “α + β + γ”, the door body 112 on the door bottom side hits the door stop 210 when attempting to fully open, and the door cannot be fully opened completely. Therefore, it is necessary to set the relational expression “A−B> α + β + γ”.

そして、この実施例においては、「α＋β＋γ」＝２＋３０＋４５＝７７ｍｍであるが、戸尻側の扉体１１２の横幅方向の寸法Ｂを、戸先側の扉体１１１の横幅方向の寸法「Ａ＋Ｂ」の１／２よりも４５ｍｍ短く設定してあるため、「Ａ−Ｂ」＝９０ｍｍであり、前記「Ａ−Ｂ ＞ α＋β＋γ」の関係式を満たしている。
このため、扉をどちら側にも開いた場合にも、戸尻側の扉体１１２が床付け戸当り２１０に当接することがなく、全開することができるものである。また、全開した位置において、戸先側の扉体１１１が確実に戸当り２１０に当接して扉が止まるため、それ以上壁側に扉を持っていかれて、壁や扉を傷つけてしまうこともないものである。 In this embodiment, “α + β + γ” = 2 + 30 + 45 = 77 mm, but the dimension B in the width direction of the door body 112 on the door bottom side is equal to the dimension “A + B” in the width direction of the door body 111 on the door end side. Since it is set shorter than 1/2 by 45 mm, “A−B” = 90 mm, which satisfies the relational expression “A−B> α + β + γ”.
For this reason, even when the door is opened on either side, the door body 112 on the door bottom side does not come into contact with the flooring door stop 210 and can be fully opened. In addition, in the fully opened position, the door body 111 on the door tip side securely contacts the door stop 210 and stops the door, so that the door may be held further on the wall side and the wall or door may be damaged. There is nothing.

図８及び図９は、床付け戸当り２１０を、扉をどちら側に全開した場合にも戸先側の扉体１１１に当接するように両側に一対設けた場合の、他の実施例を示す図である。この実施例は、最も太い部分の直径γが５０ｍｍの戸当りを、図６及び図７の実施例とほぼ同じ位置に取り付けた例である。この場合、図８に示すように、扉を全開した場合の、前記戸先側の扉体１１１の戸先部分１１１ｂとの境界Ｓから、戸尻側方向への戸当り２１０の円周部分端部までの長さαは−０．５ｍｍである。また、戸先側の扉体１１１と戸尻側の扉体１１２との接続部分の各扉体における横幅方向の長さβ（すなわち、歯車部材１１３ａの軸心部Ｒから、閉塞部材１１４の円弧状先端部分までの長さβ）は、図６及び図７の実施例と同じく３０ｍｍであるとする。   8 and 9 show another embodiment in which a pair of floor-mounted doors 210 are provided on both sides so as to contact the door body 111 on the door end side when the door is fully opened on either side. FIG. This embodiment is an example in which a door end having a diameter γ of 50 mm of the thickest portion is attached at substantially the same position as the embodiment of FIGS. 6 and 7. In this case, as shown in FIG. 8, when the door is fully opened, from the boundary S with the door tip portion 111 b of the door body 111 on the door tip side, the circumferential partial end of the door stop 210 in the door bottom side direction The length α to the part is −0.5 mm. Further, the length β in the width direction of each door body at the connecting portion between the door body 111 on the door end side and the door body 112 on the door bottom side (that is, from the axial center portion R of the gear member 113a, the circle of the closing member 114). The length β) to the arcuate tip is assumed to be 30 mm as in the embodiment of FIGS.

このとき、「α＋β＋γ」＝−０．５＋３０＋５０＝７９．５ｍｍであるが、この実施例においても、戸尻側の扉体１１２の横幅方向の寸法Ｂを、戸先側の扉体１１１の横幅方向の寸法「Ａ＋Ｂ」の１／２よりも４５ｍｍ短く設定してあるため、「Ａ−Ｂ」＝９０ｍｍであり、前記「Ａ−Ｂ ＞ α＋β＋γ」の関係式を満たしている。
よって、この実施例においても、扉をどちら側にも開いた場合にも、戸尻側の扉体１１２が床付け戸当り２１０に当接することがなく、全開することができるものである。また、全開した位置において、戸先側の扉体１１１が確実に戸当り２１０に当接して扉が止まるため、それ以上、壁側に扉を持っていかれて、壁や扉を傷つけてしまうこともないものである。 At this time, “α + β + γ” = − 0.5 + 30 + 50 = 79.5 mm, but also in this embodiment, the dimension B in the width direction of the door body 112 on the door bottom side is equal to the width direction of the door body 111 on the door end side. Therefore, “A−B” = 90 mm, which satisfies the relational expression “A−B> α + β + γ”.
Therefore, also in this embodiment, even when the door is opened on either side, the door body 112 on the door bottom side does not come into contact with the flooring door stop 210 and can be fully opened. In addition, in the fully opened position, the door-side door body 111 reliably contacts the door stop 210 and stops the door, so that the door is further brought to the wall side and the wall or door is damaged. There is nothing.

なお、本実施の形態のように、戸尻側の扉体１１２の横幅方向の寸法Ｂ、すなわち、前記基軸部１４０の回動中心Ｐから前記戸尻側の扉体１１２に取り付けられた歯車部材１１３ａの軸心部Ｒまでの長さＢが、戸先側の扉体１１１の横幅方向の寸法「Ａ＋Ｂ」の１／２より短く設定されている場合には、基軸部１４０の回動中心Ｐから戸尻側の扉体１１２の戸尻側先端までの距離をＣとすると、Ｃ＜Ｂであれば、「Ｂ＋Ｃ」が「Ａ＋Ｂ」の１／２よりも短くなくてもよいことは、言うまでもない。逆に、「Ｂ＋Ｃ」が「Ａ＋Ｂ」の１／２よりも短ければ、Ｂが「Ａ＋Ｂ」の１／２よりも短いことは自明である。
また、本実施の形態においては、寸法Ｂを「基軸部１４０の回動中心Ｐから戸尻側の扉体１１２に取り付けられた歯車部材１１３ａの軸心部Ｒまでの長さ」としたが、「基軸部１４０の回動中心Ｐから戸尻側の扉体１１２に設けられた歯車部材１１３ａ（または閉塞部材１１４）の先端部分までの長さ」としてもよい。この場合には、前記β＝０として計算される。
さらに、戸先側の扉体１１１に境界Ｓがない場合など、寸法Ａを戸先側の扉体１１１の先端まで含めて計算し、各寸法を設定することも可能である。
また、このように寸法Ａ，Ｂをどこまでの長さとするかにより寸法の関係は変わってくるが、「Ｂ＋β」が「Ａ＋Ｂ＋β」の１／２よりも短いことが好ましい。 As in the present embodiment, the dimension B in the width direction of the door body 112 on the door butt side, that is, a gear member attached to the door body 112 on the door butt side from the rotation center P of the base shaft portion 140. When the length B to the shaft center portion R of 113a is set to be shorter than 1/2 of the dimension “A + B” of the door body 111 on the door end side, the rotation center P of the base shaft portion 140 is set. Assuming that the distance from the door edge 112 to the door edge side tip of the door edge side is C, it is needless to say that if C <B, “B + C” may not be shorter than 1/2 of “A + B”. Yes. Conversely, if “B + C” is shorter than ½ of “A + B”, it is obvious that B is shorter than ½ of “A + B”.
Further, in the present embodiment, the dimension B is “the length from the rotation center P of the base shaft portion 140 to the shaft center portion R of the gear member 113a attached to the door body 112 on the door bottom side” “The length from the rotation center P of the base shaft portion 140 to the tip end portion of the gear member 113a (or the closing member 114) provided on the door body 112 on the door bottom side” may be used. In this case, it is calculated as β = 0.
Furthermore, when the door-side door body 111 does not have the boundary S, the dimension A can be calculated including the tip of the door-side door body 111 and each dimension can be set.
In addition, the relationship of the dimensions varies depending on how long the dimensions A and B are set as described above, but “B + β” is preferably shorter than ½ of “A + B + β”.

また、本実施の形態におけるヒンジ機構１１３に代えて、例えば特許文献２〜４等に記載されているような各扉体の動きが略同様となる他の方式のヒンジ機構を用いる場合には、本実施の形態におけるヒンジ機構１１３を用いた場合の動作原理に置き換えて寸法設定の基準位置を定めればよい。すなわち、他の方式のヒンジ機構において、本実施の形態におけるヒンジ機構１１３の軸心部Ｒ，Ｒに略相当する点を仮想軸心部Ｒ’，Ｒ’（図示せず）としたときに、本実施の形態における軸心部Ｒ，Ｒに代えて前記Ｒ’，Ｒ’を寸法Ａ，Ｂの基準線とすればよい。   Further, in place of the hinge mechanism 113 in the present embodiment, when using another type of hinge mechanism in which the movement of each door body is substantially the same as described in, for example, Patent Documents 2 to 4, etc., The reference position for dimension setting may be determined in place of the operating principle when the hinge mechanism 113 in this embodiment is used. In other words, in other types of hinge mechanisms, when virtual axes R ′ and R ′ (not shown) are points substantially corresponding to the axes R and R of the hinge mechanism 113 in the present embodiment, R ′ and R ′ may be used as reference lines of dimensions A and B in place of the axial centers R and R in the present embodiment.

なお、本実施の形態においては、扉を全開した場合に、戸先側の扉体１１１に当接する戸当り２１０のみを設けているが、必要に応じて、例えば図１０及び図１１に示すように、戸尻側の扉体１１２用の戸当り２１１（戸先側の扉体１１１には当接せず、戸尻側の扉体１１２にのみ当接する）をさらに設けてもよい。
また、扉を開閉する機構としては、手動の開閉扉であっても、リニアモーター式等の自動の開閉扉であっても構わない。 In this embodiment, when the door is fully opened, only the door stop 210 that comes into contact with the door body 111 on the door end side is provided. However, for example, as shown in FIGS. Further, a door stop 211 for the door body 112 on the door butt side (not contacting the door body 111 on the door tip side but contacting only the door body 112 on the door butt side) may be further provided.
The mechanism for opening and closing the door may be a manual door or an automatic door such as a linear motor.
