By attaching the first uniaxial hinge 52 near the door trailing edge side frame member 11, the link member 51 has the axial center portion of the first uniaxial hinge 52 as the first rotation center c1 and the first uniaxial hinge. By attaching the second uniaxial hinge 53 closer to the door tip than 52, the axial center portion of the second uniaxial hinge 53 is used as the second rotation center c2.

このリンク部材５１には、その表面の略全部を覆うように、矩形平板状のカバープレート５４が、止着具３５によって止着固定される。
このカバープレート５４は、第１の一軸ヒンジ５２や第２の一軸ヒンジ５３等を止着するための孔等を覆い隠すためのものであり、省くことも可能である。 A cover plate 54 in the form of a rectangular flat plate is fastened and fixed to the link member 51 by fasteners 35 so as to cover substantially the entire surface thereof.
The cover plate 54 is for covering holes for fixing the first uniaxial hinge 52, the second uniaxial hinge 53, etc., and can be omitted.

第１の一軸ヒンジ５２は、支持部材５２ａに対し回動部材５２ｂを回転自在かつ着脱可能に枢支したものである。この第１の一軸ヒンジ５２には、一般的な旗蝶番を用いることが可能である。 The first uniaxial hinge 52 rotatably and detachably pivots a rotating member 52b with respect to a supporting member 52a. A common flag hinge can be used for this first uniaxial hinge 52 .

そして、軸受部５２ａ１の中心が、建具２０の開閉動作に伴いリンク部材５１が回転する際の第１の回転中心ｃ１として機能する（図７参照）。 According to the illustrated example, the support member 52a is formed in a substantially rectangular flat plate shape, and has a tubular bearing portion 52a1 at one end side in the width direction thereof.
The support member 52a has a flat plate-like portion fixed to the back surface of the link member 51 (the surface on the side of the fitting 20) with the bearing portion 52a1 facing up and down near the door tail. According to the illustrated example, this fixing means is a fixing device 35 (for example, screws, bolts, rivets, etc.), but other fixing means such as welding can also be used.
The center of the bearing portion 52a1 functions as a first rotation center c1 when the link member 51 rotates as the fitting 20 is opened and closed (see FIG. 7).

回動部材５２ｂは、第１の回転中心ｃ１上において、支持部材５２ａに対し上下方向（図示例によれば、下側）に並設される部材であり、略矩形平板状に形成される。この回動部材５２ｂの横幅方向の一端側には、支持部材５２ａ側へ突出するように、略円柱状の軸部５２ｂ１が設けられる（図４及び図５参照）。 The rotating member 52b is arranged in parallel with the support member 52a in the vertical direction (on the lower side in the illustrated example) on the first rotation center c1, and is formed in a substantially rectangular flat plate shape. A substantially cylindrical shaft portion 52b1 is provided at one end of the rotating member 52b in the width direction so as to protrude toward the supporting member 52a (see FIGS. 4 and 5).

軸部５２ｂ１は、支持部材５２ａの軸受部５２ａ１に嵌り合うことで、支持部材５２ａを回動自在に支持する。この軸部５２ｂ１は、軸受部５２ａ１に対し軸方向へ抜き差し可能である。 The shaft portion 52b1 rotatably supports the support member 52a by fitting into the bearing portion 52a1 of the support member 52a. The shaft portion 52b1 is axially removable from the bearing portion 52a1.

上記構成の回動部材５２ｂは、軸部５２ｂ１を手前側に配置するようにして、止着具３５により戸尻側枠部材１１へ止着固定される（図４参照）。 The rotating member 52b configured as described above is fixed to the door trailing edge side frame member 11 by a fixing member 35 so that the shaft portion 52b1 is arranged on the front side (see FIG. 4).

第２の一軸ヒンジ５３は、上記第１の一軸ヒンジ５２と略同様に、支持部材５３ａに対し回動部材５３ｂを回転自在かつ着脱可能に枢支している。 The second uniaxial hinge 53, in substantially the same manner as the first uniaxial hinge 52, rotatably and detachably pivots a rotating member 53b with respect to the supporting member 53a.

この支持部材５３ａは、軸部５３ａ１を戸先寄りで上方へ向けるようにして、スペーサ５５を介してリンク部材５１の裏側に固定される。軸部５３ａ１の中心は、建具２０の押し込み動作（図７（ａ３）（ｂ３）参照）に伴い基板５７がリンク部材５１に相対し回転する際の第２の回転中心ｃ２として機能する。
支持部材５３ａをリンク部材５１に固定する手段は、図示例によれば、止着具３５を用いた止着としているが、溶接等の他の固定手段とすることも可能である。 The support member 53a has the same configuration as the rotating member 52b of the first uniaxial hinge 52, and has a substantially cylindrical shaft portion 53a1 protruding in one direction in the vertical direction at one end in the width direction (Fig. 4). reference).
The support member 53a is fixed to the back side of the link member 51 via a spacer 55 with the shaft portion 53a1 directed upward near the door. The center of the shaft portion 53a1 functions as a second rotation center c2 when the substrate 57 rotates relative to the link member 51 as the fitting 20 is pushed (see FIGS. 7(a3) and 7(b3)).
According to the illustrated example, the means for fixing the support member 53a to the link member 51 is the fastening using the fastening tool 35, but other fastening means such as welding can also be used.

スペーサ５５は、支持部材５３ａとリンク部材５１の間に挟まれる矩形平板状の部材である。図示例以外の他例としては、このスペーサ５５を、支持部材５３ａやリンク部材５１に一体に形成された部位とすることが可能である。 The spacer 55 is a rectangular plate-like member sandwiched between the support member 53 a and the link member 51 . As another example other than the illustrated example, the spacer 55 can be a portion integrally formed with the support member 53 a and the link member 51 .

回動部材５３ｂは、第１の一軸ヒンジ５２の支持部材５２ａと同構成の部材であり、横幅方向の一端側に筒状の軸受部５３ｂ１を有する。
この回動部材５３ｂは、軸受部５３ｂ１を戸先寄りで上下方向へ向けるようにして、回動部材５３ｂの平板状の部分が、スペーサ５６を介して、基板５７に固定される（図４参照）。この固定手段は、図示例によれば、止着具３５（例えば、ねじやボルト、リベット等）を用いた止着としているが、溶接等の他の固定手段とすることも可能である。 The rotating member 53b has the same configuration as the support member 52a of the first uniaxial hinge 52, and has a cylindrical bearing portion 53b1 on one end side in the width direction.
The rotating member 53b is fixed to a substrate 57 via a spacer 56 so that the bearing portion 53b1 is oriented in the vertical direction near the front door (see FIG. 4). ). According to the illustrated example, this fixing means is a fixing device 35 (for example, screws, bolts, rivets, etc.), but other fixing means such as welding can also be used.

スペーサ５６は、回動部材５３ｂと基板５７の間に挟まれる矩形平板状の部材である。図示例以外の他例としては、このスペーサ５６を、回動部材５３ｂ又は基板５７に一体に形成された部位とすることが可能である。 The spacer 56 is a rectangular plate-like member sandwiched between the rotating member 53 b and the substrate 57 . As another example other than the illustrated example, the spacer 56 can be a portion formed integrally with the rotating member 53 b or the substrate 57 .

基板５７は、適宜な剛性及び厚みを有する矩形平板状の部材であり、建具２０の表板２１に対し、止着具３５によって固定される。 The substrate 57 is a rectangular plate-shaped member having suitable rigidity and thickness, and is fixed to the front plate 21 of the fitting 20 by the fasteners 35 .

図示例において、基板５７に挿通される止着具３５は、表板２１を貫通して、表板２１の裏側の補強板５８に螺合して締め付けられる。
なお、図示例以外の他例としては、補強板５８を省いて、基板５７を表板２１に直接螺合した態様や、基板５７を表板２１に溶接した態様等とすることも可能である。 In the illustrated example, the fastener 35 inserted through the base plate 57 passes through the front plate 21 and is screwed to the reinforcing plate 58 on the back side of the front plate 21 and tightened.
In addition to the illustrated example, it is also possible to omit the reinforcing plate 58 and directly screw the substrate 57 to the top plate 21, or weld the substrate 57 to the top plate 21. .

上記構成の二軸ヒンジＡによれば、リンク部材５１は、第１の回転中心ｃ１を支点にして戸尻側枠部材１１に回転可能に支持されるとともに、第２の回転中心ｃ２を支点にして基板５７及び建具２０を回転可能に支持する。 According to the biaxial hinge A configured as described above, the link member 51 is rotatably supported by the door trailing-side frame member 11 about the first rotation center c1, and about the second rotation center c2. to rotatably support the substrate 57 and fittings 20 .

また、二軸ヒンジＢは、上記構成の二軸ヒンジＡについて、第１の回転中心ｃ１と第２の回転中心ｃ２の間の軸間距離を短くしたものである。
具体的に説明すれば、図示例の二軸ヒンジＢは、上記二軸ヒンジＡにおけるリンク部材５１、カバープレート５４、及び基板５７を、それぞれ、リンク部材５１’、カバープレート５４’、及び補強板５８’に置換したものである。
リンク部材５１’、カバープレート５４’、及び補強板５８’は、それぞれ、リンク部材５１、カバープレート５４、及び基板５７と、横幅方向の寸法が異なる。 Further, the biaxial hinge B is obtained by shortening the interaxial distance between the first rotation center c1 and the second rotation center c2 of the biaxial hinge A configured as described above.
Specifically, the illustrated biaxial hinge B replaces the link member 51, the cover plate 54, and the substrate 57 of the biaxial hinge A with the link member 51', the cover plate 54', and the reinforcing plate, respectively. 58'.
The link member 51', the cover plate 54', and the reinforcing plate 58' are different from the link member 51, the cover plate 54, and the substrate 57 in widthwise dimension.

すなわち、二軸ヒンジＡの軸間距離ｗ１と、二軸ヒンジＢの軸間距離ｗ２は、異なる。
二軸ヒンジＡの軸間距離ｗ１と、二軸ヒンジＢの軸間距離ｗ２の比（Ｗ１／Ｗ２）は、建具２０の大きさ等に応じて適宜に設定され、例えば、１．１～５．０の範囲内に設定される。図示例の建具装置１では、ｗ１：ｗ２≒２：１にしている。 That is, the inter-axis distance w1 of the biaxial hinge A and the inter-axis distance w2 of the biaxial hinge B are different.
A ratio (W1/W2) between the distance w1 between the axes of the biaxial hinge A and the distance w2 between the axes of the biaxial hinge B (W1/W2) is appropriately set according to the size of the fittings 20, and is, for example, 1.1 to 5.0. It is set in the range of .0. In the fitting device 1 of the illustrated example, w1:w2≈2:1.

上記構成の二軸ヒンジＡ，Ｂは、上下方向に間隔を置いて複数配設される。図１に示す一例によれば、二軸ヒンジＢが建具２０の上端寄りと下端寄りにそれぞれ配設され、これらの間に二軸ヒンジＡが配設される。 A plurality of the biaxial hinges A and B configured as described above are arranged at intervals in the vertical direction. According to the example shown in FIG. 1, the biaxial hinges B are arranged near the upper end and the lower end of the fitting 20, respectively, and the biaxial hinge A is arranged therebetween.

次に、建具２０を枠体１０に吊り込む作業について説明する。
この作業においては、建具２０が吊り込まれる前に、戸尻側枠部材１１に対し、二軸ヒンジＡを構成する第１の一軸ヒンジ５２の回動部材５２ｂと、二軸ヒンジＢを構成する第１の一軸ヒンジ５２の回動部材５２ｂが、それぞれ固定される。
そして、建具２０に対しては、二軸ヒンジＡを構成する第２の一軸ヒンジ５３の回動部材５３ｂが、スペーサ５６及び基板５７等を介して固定され、同様に、二軸ヒンジＢを構成する第２の一軸ヒンジ５３の回動部材５３ｂが、スペーサ５６及び基板５７’等を介して固定される。 Next, the work of hanging the fittings 20 on the frame 10 will be described.
In this work, before the fitting 20 is hung, the rotating member 52b of the first uniaxial hinge 52 constituting the biaxial hinge A and the biaxial hinge B are constructed with respect to the door tail side frame member 11. The rotating members 52b of the first uniaxial hinges 52 are respectively fixed.
Then, the rotating member 53b of the second uniaxial hinge 53 that constitutes the biaxial hinge A is fixed to the fitting 20 via a spacer 56, a substrate 57, etc. Similarly, a biaxial hinge B is constructed. A rotating member 53b of the second uniaxial hinge 53 is fixed via a spacer 56, a substrate 57', and the like.

また、二軸ヒンジＡのリンク部材５１に対しては、第１の一軸ヒンジ５２の支持部材５２ａと、第２の一軸ヒンジ５３の支持部材５３ａとが、それぞれ固定される（図５参照）。
リンク部材５１、支持部材５２ａ、支持部材５３ａ、スペーサ５５、及びカバープレート５４等は、予め一体的に組付けて、一部品として扱うことが可能である。 A support member 52a of the first uniaxial hinge 52 and a support member 53a of the second uniaxial hinge 53 are fixed to the link member 51 of the biaxial hinge A (see FIG. 5).
The link member 51, the support member 52a, the support member 53a, the spacer 55, the cover plate 54, and the like can be integrally assembled in advance and handled as a single component.

同様に、二軸ヒンジＢを構成するリンク部材５１’に対しても、第１の一軸ヒンジ５２の支持部材５２ａと、第２の一軸ヒンジ５３の支持部材５３ａとが、それぞれ固定される（図６参照）。
リンク部材５１’、支持部材５２ａ、支持部材５３ａ、スペーサ５５、及びカバープレート５４’等は、予め一体的に組付けて、一部品として扱うことが可能である。 Similarly, the support member 52a of the first uniaxial hinge 52 and the support member 53a of the second uniaxial hinge 53 are also fixed to the link member 51' that constitutes the biaxial hinge B (Fig. 6).
The link member 51', the support member 52a, the support member 53a, the spacer 55, the cover plate 54', etc. can be integrally assembled in advance and handled as a single component.

次に、二軸ヒンジＡの部分において、リンク部材５１と一体的な支持部材５２ａが、戸尻側枠部材１１側の回動部材５２ｂに組付けられる（図５参照）。
さらに、リンク部材５１と一体的な支持部材５３ａに対して、建具２０と一体的な回動部材５３ｂが組付けられる。 Next, at the portion of the biaxial hinge A, the support member 52a integrated with the link member 51 is assembled to the rotating member 52b on the side of the frame member 11 on the door bottom side (see FIG. 5).
Further, a rotating member 53b integral with the fitting 20 is assembled to the support member 53a integral with the link member 51. As shown in FIG.

同様に、二軸ヒンジＢの部分において、リンク部材５１’と一体的な第１の一軸ヒンジ５２が、戸尻側枠部材１１側の回動部材５２ｂに組付けられる（図６参照）。
さらに、リンク部材５１’と一体的な支持部材５３ａに対して、建具２０と一体的な回動部材５３ｂが組付けられる。 Similarly, at the portion of the biaxial hinge B, the first uniaxial hinge 52 integrated with the link member 51' is assembled to the rotating member 52b on the side of the frame member 11 on the door bottom side (see FIG. 6).
Further, a rotating member 53b integral with the fitting 20 is assembled to the support member 53a integral with the link member 51'.

これらの吊り込み作業よって、図２、図３及び図７に示すように、建具２０が戸尻側枠部材１１に対し開閉回動可能かつ建具厚方向へ移動可能に接続される。
この接続状態において、各リンク部材５１，５１’は、分離可能な第１の一軸ヒンジ５２及び第２の一軸ヒンジ５３により、戸尻側枠部材１１と建具２０の双方に対し着脱可能である。 As shown in FIGS. 2, 3 and 7, these hanging operations connect the fitting 20 to the door tail side frame member 11 so as to be capable of opening and closing rotation and movable in the fitting thickness direction.
In this connected state, each of the link members 51 and 51' can be attached to and detached from both the door tail side frame member 11 and the fitting 20 by the separable first uniaxial hinge 52 and second uniaxial hinge 53. As shown in FIG.

次に、上記構成の建具装置１について、建具２０を閉鎖して枠体１０内に押し込む際の作用効果を詳細に説明する。
先ず、開放状態の建具２０を閉鎖動作した場合、建具２０は、二軸ヒンジＡの部分において第１の回転中心ｃ１を中心に閉鎖方向へ回動し（図７（ａ１）参照）、同時に、二軸ヒンジＢの部分においても第１の回転中心ｃ１を中心に閉鎖方向へ回動する（図７（ｂ１）参照）。
そして、全閉状態となった建具２０は、その周縁側を、弾性部材４０に緩圧接する（図７（ａ２）（ｂ２）参照）。 Next, with respect to the fitting device 1 having the above configuration, the effects of closing the fitting 20 and pushing it into the frame 10 will be described in detail.
First, when the fitting 20 in the open state is closed, the fitting 20 rotates about the first rotation center c1 at the biaxial hinge A in the closing direction (see FIG. 7(a1)), and at the same time: The portion of the biaxial hinge B also rotates in the closing direction about the first rotation center c1 (see FIG. 7(b1)).
Then, the fitting 20 in the fully closed state is in loose pressure contact with the elastic member 40 at its peripheral edge side (see FIGS. 7(a2) and (b2)).

通常の使用状態においては、前述した全閉状態と開放状態との間で建具２０が開閉回動する。この開閉回動中（図７（ａ１）（ｂ１））は、二軸ヒンジＡと二軸ヒンジＢにおける軸間距離ｗ１，ｗ２の不揃いにより、同軸上に位置する二種類の二軸ヒンジＡ，Ｂの第１の回転中心ｃ１を支点にした回動の抵抗よりも、同軸上に位置しない二軸ヒンジＡの第２の回転中心ｃ２と二軸ヒンジＢの第２の回転中心ｃ２を支点にした回動の抵抗の方が大きくなる。
言い換えれば、二軸ヒンジＡの第２の回転中心ｃ２と二軸ヒンジＢの第２の回転中心ｃ２とが同軸上に位置しないことから、二軸ヒンジＡの第２の一軸ヒンジ５３と二軸ヒンジＢの第２の一軸ヒンジ５３とが相互に回動を規制し合う。
このため、建具２０の開閉回動中においては、二軸ヒンジＡ，Ｂの第１の回転中心ｃ１を支点にした回動のみが行われ、建具２０が二つの第２の回転中心ｃ２，ｃ２を支点にした回動により戸厚方向へぐらつくようなことを抑制することができる。 In a normal use state, the fitting 20 is opened and closed and rotated between the fully closed state and the open state described above. During this opening and closing rotation (FIGS. 7(a1) and (b1)), the two types of biaxial hinges A, With the second rotation center c2 of the biaxial hinge A and the second rotation center c2 of the biaxial hinge B, which are not coaxially located, as the fulcrum, rather than the resistance of rotation with the first rotation center c1 of B as the fulcrum. The resistance of the rotation becomes larger.
In other words, since the second rotation center c2 of the biaxial hinge A and the second rotation center c2 of the biaxial hinge B are not coaxially positioned, the second uniaxial hinge 53 of the biaxial hinge A and the biaxial hinge The hinge B and the second uniaxial hinge 53 mutually restrict rotation.
Therefore, during the opening and closing rotation of the fittings 20, only the rotation about the first rotation centers c1 of the biaxial hinges A and B is performed, and the fittings 20 are rotated around the two second rotation centers c2 and c2. It is possible to suppress wobbling in the door thickness direction due to rotation about the fulcrum.

洪水等のために止水を要する場合には、前記全閉状態において、押込み装置３０が操作され、建具２０が見込み方向に沿って屋内側へ移動し、建具２０の周縁側が、枠体１０と一体的な弾性部材４０に強く圧接される（図７（ａ３）（ｂ３）参照）。このため、建具２０と枠体１０の間の隙間が、略塞がれて、止水作用を発揮する。 When it is necessary to stop water due to flooding or the like, the push-in device 30 is operated in the fully closed state to move the fittings 20 indoors along the direction of projection, so that the peripheral edge side of the fittings 20 moves toward the frame body 10. 7 (a3) and (b3). Therefore, the gap between the fittings 20 and the frame body 10 is substantially closed, and a water stop function is exhibited.

このような止水動作においては、二軸ヒンジＡのリンク部材５１と、二軸ヒンジＢのリンク部材５１’が、それぞれ、第１の回転中心ｃ１を支点にして屋内側へ回動するとともに、建具２０が第２の回転中心ｃ２を支点にして屋外側へ回動する。そして、これら二種類の回動により、建具２０が屋内側へ略平行に移動する。この移動に伴う、リンク部材５１における第１の回転中心ｃ１を支点にした回転角度α１は、リンク部材５１’における第１の回転中心ｃ１を支点にした回転角度α２よりも小さい（図７（ａ３）（ｂ３）参照）。 In such a water stopping operation, the link member 51 of the biaxial hinge A and the link member 51' of the biaxial hinge B rotate toward the indoor side about the first rotation center c1 as a fulcrum. The fitting 20 rotates to the outside with the second rotation center c2 as a fulcrum. These two types of rotation move the fitting 20 substantially parallel to the indoor side. The rotation angle α1 about the first rotation center c1 of the link member 51 accompanying this movement is smaller than the rotation angle α2 about the first rotation center c1 of the link member 51′ (Fig. 7 (a3 ) (see b3)).

よって、上記構成の建具装置１によれば、通常時は、建具２０の厚み方向のぐらつきを抑制して、建具２０を第１の回転中心ｃ１を支点にしてスムーズに開閉回動することができる。
また、水害時等には、閉鎖状態の建具２０を見込み方向へ平行に移動させて弾性部材４０に強く圧接し、良好な止水性能を発揮することができる。
また、第１の一軸ヒンジ５２又は第２の一軸ヒンジ５３を分離することで、建具２０を枠体１０に対し容易に着脱することができ、施工性やメンテナンス性に優れている。 Therefore, according to the fitting device 1 configured as described above, normally, the fitting 20 is prevented from wobbling in the thickness direction, and the fitting 20 can be smoothly opened and closed and rotated around the first rotation center c1 as a fulcrum. .
Also, in the event of flood damage, etc., the fittings 20 in the closed state can be moved in parallel in the prospective direction to strongly press against the elastic member 40, thereby exhibiting excellent water stopping performance.
Moreover, by separating the first uniaxial hinge 52 or the second uniaxial hinge 53, the fitting 20 can be easily attached to and detached from the frame 10, which is excellent in workability and maintainability.

It is also possible to make it substantially flush with the surface.

It is also possible to configure a double-opening type (so-called double-door type) opening and closing door. should be set.

また、上記実施態様では、特に好ましい一例として、建具装置１を止水扉装置として構成したが、この建具装置１の基本構造は、例えば防音扉装置等、止水扉装置以外の気密扉装置に適用することが可能である。
さらに、建具装置１の基本構造は、例えば建具を回動して開閉する窓装置や障子等、扉装置以外の建具装置に適用することが可能である。 In the above-described embodiment, as a particularly preferred example, the fitting device 1 is configured as a water stop door device, but the basic structure of this fitting device 1 may be applied to an airtight door device other than a water stop door device, such as a soundproof door device.
