この下側基軸部42は、戸尻側扉体21(又は31)側の重量を回転力に変換して、回動部42bを回転させるカム機構42abを構成している。
In addition, the lower base shaft portion 42 is supported by a substantially L-shaped fixing portion 42a fixed to the vertical frame 11 (or 12), which is a non-moving portion, and rotatably supported by the fixing portion 42a. It consists of the rotation part 42b fixed to the lower part of the door bottom side door body 21 (or 31).
The lower base shaft portion 42 constitutes a cam mechanism 42ab that converts the weight of the door butt side door body 21 (or 31) side into a rotational force and rotates the rotating portion 42b.

このカム機構42abは、より詳細に説明すれば、固定部42aにおける回転中心部の周りに、戸尻側扉体21(又は31)の閉鎖回転方向へ向かって下り傾斜する傾斜面42a1を設け、その一方で、回動部42bにおける回転中心部の周りには、前記傾斜面42a1に摺接可能な摺接部42b1を設けてなる。
前記傾斜面42a1は、図示例によれば、略V字状の溝における底面の一方側部分として構成される。また、前記摺接部42b1は、略V字状の突起として構成される。
More specifically, the cam mechanism 42ab is provided with an inclined surface 42a1 that is inclined downward toward the closing rotation direction of the door-side door body 21 (or 31) around the rotation center portion of the fixed portion 42a. On the other hand, a slidable contact portion 42b1 slidably contactable with the inclined surface 42a1 is provided around the rotation center portion of the rotating portion 42b.
According to the illustrated example, the inclined surface 42a1 is configured as one side portion of the bottom surface of the substantially V-shaped groove. The sliding contact portion 42b1 is configured as a substantially V-shaped protrusion.

前記カム機構42abの作用を詳細に説明すれば、戸尻側扉体21(又は31)が略全開した状態から閉鎖方向へ回転すると、それに伴って、回動部42bが固定部42aに対し略直交する状態(図8に示す状態)から一方向(図8によれば反時計方向)へ回転する。
この回転の際、図8に示す最初の角度θの範囲においては、回動部42bは、図9(a)に示すように摺接部42b1を、固定部42aの平坦状の上端面に摺接させることになる。
そして、回動部42bの回転角が前記角度θを超えると、図9(b)に示すように、回動部42bの摺接部42b1が、固定部42aの傾斜面42a1を滑り下りるため、回動部42bおよび戸尻側扉体21(又は31)の閉鎖方向への回転力が発生し、回転が加速されることになる。
よって、戸尻側扉体21(又は31)の閉鎖回転の後半で、上側基軸部41の捻りバネ41b1の捻り力が弱まったとしても、上記カム機構42abによる回転力によって、戸尻側扉体21(又は31)を、全閉位置となるまで自動的に回転させることができる。
The operation of the cam mechanism 42ab will be described in detail. When the door-end side door body 21 (or 31) rotates in the closing direction from the substantially fully opened state, the rotating portion 42b substantially corresponds to the fixed portion 42a. It rotates in the one direction (counterclockwise according to FIG. 8) from the orthogonal state (the state shown in FIG. 8).
During this rotation, within the range of the initial angle θ shown in FIG. 8, the rotating part 42b slides the sliding contact part 42b1 on the flat upper end surface of the fixed part 42a as shown in FIG. 9A. Will be in contact.
When the rotation angle of the rotating part 42b exceeds the angle θ, as shown in FIG. 9B, the sliding contact part 42b1 of the rotating part 42b slides down the inclined surface 42a1 of the fixing part 42a. A rotational force in the closing direction of the rotating portion 42b and the door-end side door body 21 (or 31) is generated, and the rotation is accelerated.
Therefore, even if the torsional force of the torsion spring 41b1 of the upper base shaft portion 41 is weakened in the second half of the closing rotation of the doorside door body 21 (or 31), the doorside door body is caused by the rotational force of the cam mechanism 42ab. 21 (or 31) can be automatically rotated until it is in the fully closed position.

また、戸尻側扉体21(又は31)が全閉位置となった際には、その全閉状態が、傾斜面42a1を構成するV字状の溝と、摺接部42b1を構成するV字状の突起との嵌り合いによって維持されることになる。   Further, when the door butt side door body 21 (or 31) is in the fully closed position, the fully closed state is the V-shaped groove that forms the inclined surface 42a1 and the V that forms the sliding contact portion 42b1. It is maintained by fitting with the letter-shaped protrusion.

なお、図8に示す好ましい一例によれば、傾斜面42a1と略同様に作用する傾斜面42a1’を、固定部42aにおける傾斜面42a1よりも回転中心側に配設し、また、回動部42bにおける対向する箇所には摺接部42b1と略同様に作用する摺接部(図示せず)を設けてあるが、何れか一方の傾斜面42a1(42a1’)及び対応する摺接部を省くことも可能である。   According to a preferred example shown in FIG. 8, the inclined surface 42a1 ′ acting substantially the same as the inclined surface 42a1 is disposed closer to the rotation center than the inclined surface 42a1 in the fixed portion 42a, and the rotating portion 42b. Is provided with a sliding contact portion (not shown) that acts in substantially the same manner as the sliding contact portion 42b1, but omits one of the inclined surfaces 42a1 (42a1 ′) and the corresponding sliding contact portion. Is also possible.

また、戸先側扉体22(又は32)を開口部Sの幅方向へ導くガイド機構50は、折戸部20,30の上方の上枠13内に開口部幅方向へわたって固定されたガイドレール51(図3参照)と、該ガイドレール51に沿って開口部幅方向へ移動可能な左右のブロック状の移動支持部52a,52bとから構成され、各移動支持部52a(又は52b)には、戸先側扉体22(又は32)が開閉回動可能に吊持されている。   The guide mechanism 50 for guiding the door-end side door body 22 (or 32) in the width direction of the opening S is a guide fixed in the width direction of the opening in the upper frame 13 above the folding door portions 20 and 30. A rail 51 (see FIG. 3) and left and right block-like movement support portions 52a and 52b that can move in the width direction of the opening along the guide rail 51 are provided. Each movement support portion 52a (or 52b) The door end side door body 22 (or 32) is suspended so as to be capable of opening and closing.

また、連動機構60は、両折戸部20,30の上方側に、左右一対の回転体61,61にわたって掛け回された無端輪状部材62と、二つの揺動部材63,64とを具備して構成される。
この連動機構60は、一方の折戸部20(又は30)の開放初期動作を、揺動部材63(又は64)によって他方の折戸部30(又は20)に連動させ、更に、その開放動作を無端輪状部材62によって継続する。
Further, the interlocking mechanism 60 includes an endless ring-shaped member 62 hung over a pair of left and right rotating bodies 61 and 61 and two swinging members 63 and 64 on the upper side of the folding door portions 20 and 30. Composed.
This interlocking mechanism 60 interlocks the opening initial operation of one folding door portion 20 (or 30) with the other folding door portion 30 (or 20) by the swing member 63 (or 64), and further, the opening operation is endless. Continue with the ring-shaped member 62.

より詳細に説明すれば、図6に示すように、無端輪状部材62は、上枠13内の一端側に回動自在な滑車状に支持された回転体61と、同上枠13内の他端側に回動自在な滑車状に支持された回転体61との間に、掛け回される。
したがって、これら二つの回転体61,61間に掛け回された無端輪状部材62には、二つの直線状部分62a,62bを有することになる。
そして、一方の直線状部分62aには、一方の移動支持部52aが接続され、他方の直線状部分62bには、他方の移動支持部52bが接続される。
したがって、一方の移動支持部52aが一方へ直線運動すると、他方の移動支持部52bは逆方向へ直線運動することになる。
More specifically, as shown in FIG. 6, the endless ring-shaped member 62 includes a rotating body 61 that is supported in a pulley-like shape that is rotatable on one end side in the upper frame 13, and the other end in the upper frame 13. It is hung between a rotating body 61 supported in the form of a pulley that can be pivoted to the side.
Therefore, the endless ring-shaped member 62 hung between these two rotating bodies 61, 61 has two linear portions 62a, 62b.
One movement support portion 52a is connected to one linear portion 62a, and the other movement support portion 52b is connected to the other linear portion 62b.
Therefore, when one moving support portion 52a linearly moves in one direction, the other moving support portion 52b linearly moves in the opposite direction.

また、各揺動部材63(又は64)は、図4に示すように、一方の折戸部20(又は30)の開放初期動作に伴い、移動する移動支持部52a(又は52b)に当接されて一端側を揺動し、その他端側を、他方の折戸部30(又は20)における移動支持部52b(又は52a)よりも戸尻側の被当接ブラケット65に当接させることで、他方の折戸部30(又は20)を谷折状に折曲げる。   Further, as shown in FIG. 4, each swinging member 63 (or 64) is brought into contact with the moving support portion 52a (or 52b) that moves in accordance with the initial opening operation of one folding door portion 20 (or 30). One end side is swung, and the other end side is brought into contact with the abutting bracket 65 on the door bottom side of the other folding door portion 30 (or 20) with respect to the movement support portion 52b (or 52a), thereby Folding door 30 (or 20) is folded into a valley fold.

より詳細に説明すれば、一方の揺動部材63は、一方の戸先側扉体22と他方の戸先側扉体32とを跨ぐ棒状に形成され、平面視略L字状に曲げられた一端側の突端に係合ローラ63aを回動自在に支持し、他端側には幅広の押圧部63bを形成している。そして、この揺動部材63は、その長さ方向の中途箇所を支点にして、前記係合ローラ63a側の部分と押圧部63b側の部分とを交互に揺動させるように支持されている。
また、他方の揺動部材64は、前記揺動部材63と同一の部材を左右逆向きに配設してなり、その一端側に係合ローラ64aを、他端側には押圧部64bを有する。
If it demonstrates in detail, the one rocking | swiveling member 63 was formed in the rod shape ranging over one door-end side door body 22 and the other door-end side door body 32, and was bent by the planar view substantially L-shape. An engaging roller 63a is rotatably supported at the protruding end on one end side, and a wide pressing portion 63b is formed on the other end side. The swing member 63 is supported so as to alternately swing the portion on the engagement roller 63a side and the portion on the pressing portion 63b side with a halfway point in the length direction as a fulcrum.
The other swinging member 64 is formed by disposing the same member as the swinging member 63 in the left and right direction, and has an engaging roller 64a on one end side and a pressing portion 64b on the other end side. .

また、揺動部材63(又は64)の押圧部63b(又は64b)によって当接される被当接ブラケット65は、戸先側扉体22(又は32)における戸尻寄り部分の上端から上方へ突出し、前記揺動部材63の押圧部63bを受けるように配設される。   Further, the abutted bracket 65 abutted by the pressing portion 63b (or 64b) of the swinging member 63 (or 64) is upward from the upper end of the door bottom side portion of the door-end side door body 22 (or 32). It protrudes and is arranged to receive the pressing portion 63b of the swing member 63.

上記構成によれば、例えば、図4(A)に示すように、一方(図示例では左側)の折戸部20が外力を受けて開放動作を開始すると、その開放初期動作に伴って、前記折戸部20に対応する移動支持部52aが開口部開放方向(図4における左方向)へ直線運動する。
なお、前記外力は、戸尻側扉体21の取手部21aに手を掛けて引っ張る操作による力でもよいし、戸先側扉体22の取手部21aに手を掛けて引っ張る操作による力であってもよい。
更に、前記外力は、左右の戸尻側扉体21と戸先側扉体22との間を、回動方向(図4の上方)へ押す操作による力であってもよい。
According to the above configuration, for example, as shown in FIG. 4A, when one of the folding door portions 20 (left side in the illustrated example) receives an external force and starts an opening operation, the folding door is accompanied with the opening initial operation. The movement support portion 52a corresponding to the portion 20 linearly moves in the opening opening direction (left direction in FIG. 4).
The external force may be a force by an operation of pulling the handle portion 21a of the door-end side door body 21 with a hand or a force of an operation of pulling the handle portion 21a of the door-end side door body 22 with a hand. May be.
Further, the external force may be a force generated by an operation of pushing between the left and right door-end side door bodies 21 and the door-end side door body 22 in the rotation direction (upward in FIG. 4).

そして、直線運動した移動支持部52aは、一方の揺動部材63の係合ローラ63aに当接することで、揺動部材63の係合ローラ63a側の部分を折戸部20から離れる方向へ揺動させる。
そのため、揺動部材63の押圧部63bが、折戸部30上端の被当接ブラケット65を押圧し、他方の折戸部30は、図4(B)に示すように、折れ曲がるようにして開放動作を開始する。
Then, the movement support portion 52a that has linearly moved contacts the engagement roller 63a of one swinging member 63, thereby swinging the portion on the side of the engagement roller 63a of the swinging member 63 away from the folding door portion 20. Let
Therefore, the pressing portion 63b of the swinging member 63 presses the abutted bracket 65 at the upper end of the folding door portion 30, and the other folding door portion 30 opens as shown in FIG. 4B. Start.

図4(C)に示すように、一方の折戸部20を外力によって更に開放すれば、該折戸部20に対応する移動支持部52aも更に開口部開放方向(図4における左方向)へ直線運動する。
そのため、この移動支持部52aの直線運動に伴い、無端輪状部材62が回動し、他方の移動支持部52bが、移動支持部52aの移動方向とは逆の方向へ直線運動し(図6参照)、他方の折戸部30も開放動作を継続する(図4(C)〜図5(A)参照)。
As shown in FIG. 4C, if one of the folding doors 20 is further opened by an external force, the movement support 52a corresponding to the folding door 20 is further linearly moved in the opening opening direction (left direction in FIG. 4). To do.
Therefore, the endless ring-shaped member 62 is rotated along with the linear motion of the movement support portion 52a, and the other movement support portion 52b linearly moves in a direction opposite to the movement direction of the movement support portion 52a (see FIG. 6). ), The other folding door portion 30 also continues the opening operation (see FIGS. 4C to 5A).

そして、上記のように連動して開放動作する左右の折戸部20及び折戸部30は、図5(B)に示すように、略同時に全開状態となる。
この全開状態は、一方または双方の折戸部20,30が、上枠13内の図示しない係止具に係止されることで維持されるようになっている。なお、他例としては、前記係止具を省き、全開状態が維持されない態様とすることも可能である。
Then, the left and right folding door portions 20 and the folding door portion 30 that perform the opening operation in conjunction with each other as described above are fully opened as shown in FIG. 5B.
This fully open state is maintained by one or both of the folding door portions 20 and 30 being locked by a locking tool (not shown) in the upper frame 13. In addition, as another example, it is also possible to omit the locking tool and to maintain the fully open state.

そして、前記全開状態では、図5(B)に示すように、開口部S側へ各取手部21aが突出することなく、その開口部幅Wを、比較的広く確保することができる。   And in the said full open state, as shown to FIG. 5 (B), the opening part width W can be ensured comparatively widely, without each handle part 21a projecting to the opening part S side.

なお、上記動作例によれば、図示の左側の折戸部20を外力によって開放動作し、その開放動作に右側の折戸部30を連動させるようにしたが、図示の右側の折戸部30を外力によって開放動作した場合でも同様にして折戸部20が連動する。   According to the above operation example, the left folding door 20 illustrated in the figure is opened by an external force, and the right folding door 30 is interlocked with the opening operation. However, the right folding door 30 illustrated in FIG. Even when the opening operation is performed, the folding door portion 20 is interlocked in the same manner.

また、全開状態の両折戸部20,30を閉鎖動作する際には、上記とは逆の順序となる。すなわち、例えば、一方の折戸部20を外力によって閉鎖動作すれば、該折戸部20に対応する移動支持部52aが、開口部閉鎖方向(図示の右方向)へ直線運動し、その直線運動に連動して、移動支持部52bも開口部閉鎖方向(図示の左方向)へ移動する。
この際の閉鎖動作は、上側基軸部41内の捻りバネ41b1の付勢力によって補助され、更に、該閉鎖動作の途中からは、下側基軸部42の傾斜面42a1と摺接部42b1からなるカム機構42abによっても補助される。
Moreover, when closing both the folding door parts 20 and 30 of a full open state, it becomes a reverse order to the above. That is, for example, if one of the folding door portions 20 is closed by an external force, the movement support portion 52a corresponding to the folding door portion 20 linearly moves in the opening closing direction (right direction in the drawing) and interlocks with the linear movement. Then, the movement support portion 52b also moves in the opening closing direction (left direction in the drawing).
The closing operation at this time is assisted by the biasing force of the torsion spring 41b1 in the upper base shaft portion 41. Further, from the middle of the closing operation, the cam composed of the inclined surface 42a1 of the lower base shaft portion 42 and the sliding contact portion 42b1. It is also assisted by the mechanism 42ab.

したがって、左右の折戸部20,30の内の何れか一方又は双方が、基軸部40やその他の箇所の摩擦等により、閉鎖途中で停止してしまうようなことを防ぐことができる。
しかも、全閉状態では、図10に示すように、一方の折戸部20先端の弾性変形部24aと、他方の折戸部30先端の弾性変形部24aとが重なり合うが、これら弾性変形部24a,24aが双方とも薄肉状に形成されているため、一方の折戸部20(又は30)に対し他方の折戸部30(又は20)が傾斜した状態で停止するのを防ぐことができる。
Therefore, it is possible to prevent any one or both of the left and right folding door portions 20 and 30 from being stopped during closing due to friction of the base shaft portion 40 and other portions.
Moreover, in the fully closed state, as shown in FIG. 10, the elastic deformation portion 24a at the tip of one folding door portion 20 and the elastic deformation portion 24a at the tip of the other folding door portion 30 overlap, but these elastic deformation portions 24a, 24a. Since both are formed in thin shape, it can prevent that the other folding door part 30 (or 20) inclines with respect to one folding door part 20 (or 30), and stops.

なお、上記実施の形態によれば、左右の折戸部20,30の双方に対しそれぞれ取手部21aを備えたが、何れか一方の折戸部20(又は30)のみに対し取手部21aを具備した態様とすることも可能である。   In addition, according to the said embodiment, although the handle part 21a was provided with respect to both the right and left folding door parts 20 and 30, respectively, the handle part 21a was provided only with respect to any one folding door part 20 (or 30). It is also possible to adopt an aspect.

また、取手部21aの扉体幅方向(図示の左右方向)の位置は、本実施の形態の好ましい一例によれば、対応する扉体21,22,31,又は32の戸先側端部寄りの位置としたが、他例としては、戸先側端部から戸尻側へ離れた位置とすることも可能である。この場合、戸尻側扉体21(又は31)の取手部21aは、少なくとも基軸部40よりも戸先側に配置され、戸先側扉体22(又は32)の取手部21aは、少なくとも移動支持部52a(又は52b)よりも戸先側に配置される。   Further, according to a preferred example of the present embodiment, the position of the handle portion 21a in the door body width direction (the left-right direction in the drawing) is closer to the door end side end portion of the corresponding door body 21, 22, 31, or 32. However, as another example, it is also possible to set the position away from the door end side end to the door bottom side. In this case, the handle portion 21a of the door butt side door body 21 (or 31) is disposed at least on the door tip side of the base shaft portion 40, and the handle portion 21a of the door tip side door body 22 (or 32) is moved at least. It arrange | positions rather than the support part 52a (or 52b) at the door-end side.

また、上記実施の形態によれば、取手部21aを、各扉体21(又は、22,23,24)の一方の面に対し単数設けるようにしているが、他例としては、各扉体21(又は、22,23,24)の一方の面に対し、上下方向、水平方向、又は斜め方向へ、複数設けるようにしてもよい。   Moreover, according to the said embodiment, although the handle part 21a is provided with respect to one surface of each door body 21 (or 22, 23, 24), as another example, each door body You may make it provide with two or more in the up-down direction, a horizontal direction, or a diagonal direction with respect to one surface of 21 (or 22, 23, 24).

また、各取手部21aは、折戸部20(又は30)を構成している戸尻側扉体21(又は31)と戸先側扉体22(又は32)のそれぞれについて、その開放回動方向側となる一方の面と逆側の面との内の前記一方の面のみに、突出するように設けられる。すなわち、戸尻側扉体21(又は31)における一方の面と、戸先側扉体22(又は32)における他方の面とに、それぞれ突出する取手部21aが設けられ、戸尻側扉体21(又は31)における他方の面と、戸先側扉体22(又は32)における一方の面とには、突出する取手部が設けられない。
しかしながら、他例としては、各扉体21,22,31,又は32において、突出する取手部21aを設けない方の面に、略凹状などに凹んだ取手部(図示せず)を設けるようにしてもよい。
前記他例によれば、前記凹んだ取手部を引く操作により、折戸部20又は30を開閉動作することが可能となり、より開閉操作性を向上することができる。
Moreover, each handle part 21a is the opening rotation direction about each of the door bottom side door body 21 (or 31) and the door end side door body 22 (or 32) which comprises the folding door part 20 (or 30). It is provided so as to protrude only on the one surface of the one surface serving as the side and the surface on the opposite side. That is, the handle part 21a which protrudes in the one surface in the door butt side door body 21 (or 31) and the other surface in the door tip side door body 22 (or 32) is provided, respectively, and the door butt side door body is provided. A protruding handle portion is not provided on the other surface 21 (or 31) and the one surface of the door-end side door body 22 (or 32).
However, as another example, in each door body 21, 22, 31, or 32, a handle portion (not shown) recessed in a substantially concave shape or the like is provided on the surface where the protruding handle portion 21a is not provided. May be.
According to the other example, the folding door portion 20 or 30 can be opened / closed by an operation of pulling the recessed handle portion, and the opening / closing operability can be further improved.

また、上記実施の形態によれば、移動支持部52a(及び52b)がガイドレール51に沿ってスライドする構造としたが、他例としては、吊車状の移動支持部がガイドレールに沿って転動する構造(図示せず)としてもよい。
また、上記実施の形態によれば、移動支持部52a(又は52b)およびガイドレール51を、対応する戸先側扉体22(又は32)の上方側のみに設けたが、他例としては、戸先側扉体22(又は32)の下方側に設けたり、上下両側に設けたり等することも可能である。
Further, according to the above-described embodiment, the movement support portion 52a (and 52b) slides along the guide rail 51. However, as another example, the suspension-like movement support portion rolls along the guide rail. It may be a moving structure (not shown).
Moreover, according to the said embodiment, although the movement support part 52a (or 52b) and the guide rail 51 were provided only in the upper side of the corresponding door-end side door body 22 (or 32), as another example, It is also possible to provide it on the lower side of the door-end side door body 22 (or 32), or provide it on both the upper and lower sides.

また。上記実施の形態によれば、連動機構60における回転体61を滑車状に構成するとともに無端輪状部材62を無端輪状の金属製ワイヤーとしているが、他例としては、これら回転体61,61と無端輪状部材62を、ベルトとプーリー、あるいはチェーンとスプロッケットからなる機構とすることが可能である。   Also. According to the above embodiment, the rotating body 61 in the interlocking mechanism 60 is configured as a pulley and the endless ring-shaped member 62 is an endless ring-shaped metal wire. As another example, the rotating bodies 61 and 61 and the endless ring-shaped member 62 are endless. The ring-shaped member 62 can be a mechanism including a belt and a pulley, or a chain and a sprocket.

また、上記実施の形態において、各揺動部材63(又は64)は、被当接ブラケット65を介して折戸部30(又は20)における移動支持部52b(又は52a)よりも戸尻側の部分を押圧するようにしたが、被当接ブラケット65を省き、折戸部30(又は20)に対し直接的に当接する態様とすることも可能である。   Moreover, in the said embodiment, each rocking | swiveling member 63 (or 64) is a part of the door bottom side rather than the movement support part 52b (or 52a) in the folding door part 30 (or 20) via the to-be-contacted bracket 65. However, the abutted bracket 65 may be omitted, and a mode of directly contacting the folding door 30 (or 20) may be employed.

また、上記実施の形態によれば、左右の折戸部20,30の双方の閉鎖動作を、それぞれ付勢手段(詳細には捻りバネ41b1及びカム機構42ab)により付勢する構成としているが、他例としては、一方の折戸部20(又は30)の閉鎖動作のみを、前記付勢手段によって付勢する構成としてもよい。この構成においても、一方の折戸部20(又は30)の閉鎖動作を、連動機構60によって他方の折戸部30(又は20)に連動させることができる。   Further, according to the above-described embodiment, the closing operation of both the left and right folding door portions 20 and 30 is urged by the urging means (specifically, the torsion spring 41b1 and the cam mechanism 42ab).
