特開２０００−１６０９２２号公報JP 2000-160922 A

例えば特許文献１においては、障子の上部を枠体に対して昇降自在に連結している連結機構と、障子の前記上部に対して下方に配される障子の他の部位を、枠体に対して建物内外方向に移動自在に連結している連結機構とを具備しており、障子自体の重心及び障子の他の部位の相互位置との関係において障子に開口開放位置に向かう移動力を生じさせる窓開閉装置が提案されている。   For example, in Patent Document 1, a connecting mechanism that connects the upper part of the shoji to the frame so as to be movable up and down, and other parts of the shoji placed below the upper part of the shoji are attached to the frame. And a connecting mechanism that is movably connected in and out of the building, and generates a moving force toward the opening opening position of the shoji in relation to the center of gravity of the shoji itself and the mutual position of other parts of the shoji. Window opening and closing devices have been proposed.

ところで、斯かる窓開閉装置では、障子自体の重心及び障子の他の部位の相互位置との関係において障子に開口開放位置に向かう移動力を生じさせるために、障子の開口開放位置に向かう移動力を一定に近づけることが困難である。   By the way, in such a window opening and closing device, in order to generate a moving force toward the opening opening position of the shoji in relation to the center of gravity of the shoji itself and the mutual position of other parts of the shoji, the moving force toward the opening opening position of the shoji It is difficult to keep the value close to constant.

本発明は、上記諸点に鑑みてなされたものであり、その目的とするところは、障子の開口開放位置に向かう移動力を一定に近づけることのできる窓開閉装置を提供することにある。   The present invention has been made in view of the above-described points, and an object of the present invention is to provide a window opening and closing device capable of bringing the moving force of the shoji toward the opening opening position of the shoji into a constant.

本発明の窓開閉装置は、建物に装着される枠体と、枠体に画成された開口に配されていると共に当該開口を開閉する障子と、この障子が開口を開閉自在となるように、障子の上下方向における一方側の部位を枠体に対して回転自在に連結している連結手段と、障子を開口開放位置に向かって付勢すべく障子及び枠体に連結されている付勢手段とを具備しており、付勢手段は、障子の前記部位に対して上下方向において異なる位置に存する他の部位及び当該他の部位に対して上下方向において異なる位置に存する枠体の部位の夫々に回転自在に連結されていると共に回動により障子の他の部位に対して建物内側から建物外側に向かう移動力を付与する回動部材と、障子及び枠体のうちの一方に設けられていると共に回動部材の回動に伴う障子及び枠体のうちの一方に対する揺動を案内する案内路と、障子及び枠体のうちの他方に装着されている弾性部材と、回動部材に固着されていると共にカム面を有したカム部材と、弾性部材とカム部材とを連結していると共に、弾性部材の弾性により障子の他の部位に対して建物内側から建物外側に向かう移動力を付与するための回動力をカム部材を介して回動部材に与えられるようにカム面に当接する可撓性を有した可撓体とを具備しており、カム面は、当該カム面に当接する可撓体の弾性部材側における当接端部が障子の他の部位に対して建物内側から建物外側に向かう移動力を付与するための回動部材の回動において当該回動部材の障子及び枠体のうちの他方に対する回転軸心から漸次離反するように形成されている。   The window opening and closing device of the present invention is arranged such that a frame attached to a building, an opening defined in the frame, a shoji that opens and closes the opening, and the shoji can freely open and close the opening. A connecting means for rotatably connecting one side of the shoji in the vertical direction with respect to the frame, and an urging force connected to the shoji and the frame to urge the shoji toward the opening opening position. The biasing means includes other parts that are different in the vertical direction with respect to the part of the shoji and parts of the frame that are in different positions in the vertical direction with respect to the other parts. Rotating members that are rotatably connected to each other, and are provided on one of the shoji and the frame, and a turning member that applies a moving force from the inside of the building to the outside of the building with respect to the other parts of the shoji by turning. As well as the shoji A guide path for guiding swinging with respect to one of the frames, an elastic member attached to the other of the shoji and the frame, a cam member fixed to the rotating member and having a cam surface; The elastic member and the cam member are connected, and the rotational force for applying the moving force from the inside of the building to the outside of the building is rotated via the cam member to the other part of the shoji by the elasticity of the elastic member. A flexible body that is in contact with the cam surface so as to be applied to the moving member, and the cam surface is a contact end portion on the elastic member side of the flexible body that is in contact with the cam surface. In the rotation of the rotating member for applying a moving force from the inside of the building to the outside of the building with respect to other parts of the shoji, the rotating member is gradually separated from the rotation axis of the other of the shoji and the frame. It is formed to do.

本発明の窓開閉装置によれば、特に、付勢手段は、障子の前記部位に対して上下方向において異なる位置に存する他の部位及び当該他の部位に対して上下方向において異なる位置に存する枠体の部位の夫々に回転自在に連結されていると共に回動により障子の他の部位に対して建物内側から建物外側に向かう移動力を付与する回動部材と、障子及び枠体のうちの一方に設けられていると共に回動部材の回動に伴う障子及び枠体のうちの一方に対する揺動を案内する案内路と、障子及び枠体のうちの他方に装着されている弾性部材と、回動部材に固着されていると共にカム面を有したカム部材と、弾性部材とカム部材とを連結していると共に、弾性部材の弾性により障子の他の部位に対して建物内側から建物外側に向かう移動力を付与するための回動力をカム部材を介して回動部材に与えられるようにカム面に当接する可撓性を有した可撓体とを具備しており、カム面は、当該カム面に当接する可撓体の弾性部材側における当接端部が障子の他の部位に対して建物内側から建物外側に向かう移動力を付与するための回動部材の回動において当該回動部材の障子及び枠体のうちの他方に対する回転軸心から漸次離反するように形成されているために、障子による開口の開閉に伴う弾性部材の引張量、圧縮量等の変化に基づく回動部材に対する回動力の変化を減少させることができ、而して、障子の開口開放位置に向かう移動力を一定に近づけることができる。   According to the window opening and closing apparatus of the present invention, in particular, the urging means includes other parts that are different in the vertical direction with respect to the part of the shoji and frames that are different in the vertical direction with respect to the other part. A pivot member that is rotatably coupled to each of the body parts and that applies a moving force from the inside of the building toward the outside of the building with respect to the other parts of the shoji by rotation, and one of the shoji and the frame And a guide path that guides swinging of one of the shoji and the frame with the rotation of the pivoting member, an elastic member attached to the other of the shoji and the frame, The cam member that is fixed to the moving member and has a cam surface, and the elastic member and the cam member are connected to each other, and the elasticity of the elastic member leads to the other part of the shoji from the inside of the building to the outside of the building. To give movement power And a flexible body that is in contact with the cam surface so that rotational force is applied to the rotating member via the cam member, and the cam surface is in contact with the cam surface. Of the shoji and frame of the pivot member, the pivot end of the pivot member applies a moving force from the inside of the building toward the outside of the building with respect to the other part of the shoji. Since it is formed so as to be gradually separated from the rotation axis with respect to the other, the change in the rotational force with respect to the rotating member based on the change in the amount of tension, compression, etc. of the elastic member accompanying opening / closing of the opening by the shoji is reduced. Thus, the moving force toward the opening opening position of the shoji can be made close to a constant value.

本発明の窓開閉装置の好ましい例では、弾性部材は、障子の開口開放位置に向かう移動において引張量が漸減するように障子及び枠体のうちの他方に装着された引張ばねからなる。このような好ましい例によれば、障子の開口開放位置に向かう移動における弾性部材の引張量の漸減に応じて、カム面に当接する可撓体の弾性部材側における当接端部を障子の他の部位に対して建物内側から建物外側に向かう移動力を付与するための回動部材の回動において当該回動部材の障子及び枠体のうちの他方に対する回転軸心から漸次離反させることができ、而して、障子の開口開放位置に向かう移動力を一定に近づけることができる。尚、弾性部材は、引張ばねに代えて、例えば、障子の開口開放位置に向かう移動において圧縮量が漸減するように障子及び枠体のうちの他方の夫々に回転自在に連結された圧縮ばねからなっていてもよく、斯かる場合においても、障子の開口開放位置に向かう移動における弾性部材の圧縮量の漸減に応じて、カム面に当接する可撓体の弾性部材側における当接端部を障子の他の部位に対して建物内側から建物外側に向かう移動力を付与するための回動部材の回動において当該回動部材の障子及び枠体のうちの他方に対する回転軸心から漸次離反させることができ、而して、障子の開口開放位置に向かう移動力を一定に近づけることができる。   In a preferred example of the window opening and closing apparatus of the present invention, the elastic member is formed of a tension spring mounted on the other of the shoji and the frame so that the amount of tension gradually decreases when the shoji moves toward the opening opening position. According to such a preferable example, the contact end portion on the elastic member side of the flexible body that contacts the cam surface is moved to the other side of the shoji according to the gradual decrease of the tensile amount of the elastic member in the movement of the shoji toward the opening opening position. In the rotation of the rotating member for applying a moving force from the inside of the building to the outside of the building, the rotating member can be gradually separated from the rotation axis with respect to the other of the shoji and the frame of the rotating member. Thus, the moving force toward the opening opening position of the shoji can be made close to constant. Instead of the tension spring, the elastic member is, for example, a compression spring that is rotatably connected to the other one of the shoji and the frame so that the amount of compression gradually decreases as the shoji moves toward the opening opening position. Even in such a case, the contact end portion on the elastic member side of the flexible member that contacts the cam surface may be reduced according to the gradual decrease in the compression amount of the elastic member in the movement toward the opening opening position of the shoji. In the rotation of the rotating member for applying a moving force from the inside of the building toward the outside of the building with respect to the other part of the shoji, the rotating member is gradually separated from the rotation axis of the other of the shoji and the frame. Thus, the moving force toward the opening opening position of the shoji can be made close to a constant value.

本発明の窓開閉装置の好ましい例では、カム部材は、回動部材の回動において当該回動部材の障子及び枠体のうちの他方に対する回転軸心を中心として回転するように回動部材に固着されており、カム面は、回動部材の障子及び枠体のうちの一方に対する回転軸心並びに障子及び枠体のうちの他方に対する回転軸心を通る線と前記線に対して障子の開口開放位置から開口閉鎖位置までの移動における回動部材の回動角をもって交わると共に回動部材の障子及び枠体のうちの他方に対する回転軸心を通る線との間に位置するカム部材の周面の部位に形成されている。   In a preferred example of the window opening and closing apparatus according to the present invention, the cam member is arranged on the rotating member so as to rotate around the rotation axis with respect to the other of the shoji and the frame of the rotating member when the rotating member rotates. The cam surface is fixed, and the cam member has a rotation axis for one of the shoji and frame of the rotating member and a line passing through the rotation axis for the other of the shoji and frame and the opening of the shoji for the line. The peripheral surface of the cam member that intersects with the rotation angle of the rotation member in the movement from the open position to the opening closed position and is located between the shoji of the rotation member and a line passing through the rotation axis with respect to the other of the frames It is formed in the part of.

本発明の窓開閉装置の好ましい例では、カム面から回動部材の障子及び枠体のうちの他方に対する回転軸心までの距離は、回動部材の障子及び枠体のうちの一方に対する回転軸心並びに障子及び枠体のうちの他方に対する回転軸心を通る線に対して、障子の開口開放位置から開口閉鎖位置までの移動における回動部材の回動角をもって交わると共に回動部材の障子及び枠体のうちの他方に対する回転軸心を通る線上に位置するカム面の部位から回動部材の障子及び枠体のうちの一方に対する回転軸心並びに障子及び枠体のうちの他方に対する回転軸心を通る線上に位置するカム面の部位に向かうに従って漸増している。   In a preferred example of the window opening and closing apparatus of the present invention, the distance from the cam surface to the rotation axis of the other side of the pivot member and the frame is the rotation axis of the pivot member and the frame. A line passing through the rotation axis of the heart and the other of the shoji and the frame, intersects with the turning angle of the turning member in the movement from the opening open position of the shoji to the opening closing position, and the shoji of the turning member From the portion of the cam surface located on the line passing through the rotation axis for the other of the frames, the rotation axis for one of the shoji and the frame of the rotating member, and the rotation axis for the other of the shoji and the frame It gradually increases as it goes to the portion of the cam surface located on the line passing through.

本発明の窓開閉装置の好ましい例では、カム部材は、他のカム面を有しており、付勢手段は、障子及び枠体のうちの他方に装着されている他の弾性部材と、他の弾性部材とカム部材とを連結していると共に、他の弾性部材の弾性により障子の他の部位に対して建物内側から建物外側に向かう移動力を付与するための回動力をカム部材を介して回動部材に与えられるように他のカム面に当接する可撓性を有した他の可撓体とを具備しており、他のカム面は、当該他のカム面に当接する他の可撓体の他の弾性部材側における当接端部が障子の他の部位に対して建物内側から建物外側に向かう移動力を付与するための回動部材の回動において当該回動部材の障子及び枠体のうちの他方に対する回転軸心から漸次離反するように形成されている。このような好ましい例によれば、弾性部材の弾性に基づく回動部材に対するほぼ一定の回動力の付与に加えて、他の弾性部材の弾性に基づく回動部材に対するほぼ一定の回動力をも当該回動部材に付与することができ、しかも、例えば可撓体及び他の可撓体のうちの一方の意図しない切断等により弾性部材及び他の弾性部材のうちの一方の弾性に基づいて回動部材に対して回動力を付与することができなくなった場合においても、弾性部材及び他の弾性部材のうちの他方の弾性に基づいて回動部材に対して回動力を付与することができ、而して、付勢手段に意図しない支障が生じた際にも障子の急速な開口閉鎖位置に向かう移動を阻止し得る。   In a preferred example of the window opening and closing device of the present invention, the cam member has another cam surface, and the urging means includes another elastic member mounted on the other of the shoji and the frame, and the other. The elastic member and the cam member are connected to each other, and the rotational force for applying the moving force from the inside of the building to the outside of the building is applied to the other part of the shoji by the elasticity of the other elastic member via the cam member. And another flexible body having flexibility to abut against another cam surface so as to be provided to the rotating member, and the other cam surface is in contact with the other cam surface. In the rotation of the rotation member for applying a moving force from the inside of the building toward the outside of the building by the contact end on the other elastic member side of the flexible body, the obstacle of the rotation member And the other of the frame bodies are formed so as to be gradually separated from the rotation axis. According to such a preferable example, in addition to the application of the substantially constant rotational force to the rotating member based on the elasticity of the elastic member, the substantially constant rotational force to the rotating member based on the elasticity of the other elastic members is also applied. Further, it can be applied to the rotating member, and for example, it can rotate based on the elasticity of one of the elastic member and the other elastic member by unintentional cutting of one of the flexible body and the other flexible body. Even when the rotational force cannot be applied to the member, the rotational force can be applied to the rotating member based on the elasticity of the other of the elastic member and the other elastic member. Thus, even when an unintentional trouble occurs in the urging means, it is possible to prevent the shoji from moving toward the opening closed position rapidly.

本発明の窓開閉装置の好ましい例では、カム部材は、回動部材の回動において当該回動部材の障子及び枠体のうちの他方に対する回転軸心を中心として回転するように回動部材に固着されており、弾性部材、カム面及び可撓体並びに他の弾性部材、他のカム面及び他の可撓体は、回動部材の障子及び枠体のうちの他方に対する回転軸心との関係において点対称となるように夫々配されている。弾性部材及び他の弾性部材は、好ましくは互いに等しい弾性を有している。このような好ましい例によれば、弾性部材及び他の弾性部材の弾性によりカム部材に対して意図しない揺動力を与える虞をなくすことができて、回動部材に対してより好適に回動力を与えることができる。   In a preferred example of the window opening and closing apparatus according to the present invention, the cam member is arranged on the rotating member so as to rotate around the rotation axis with respect to the other of the shoji and the frame of the rotating member when the rotating member rotates. The elastic member, the cam surface, and the flexible body, and the other elastic member, the other cam surface, and the other flexible body are connected to the other one of the shoji and the frame of the rotating member. They are arranged so as to be point-symmetric in relation. The elastic member and the other elastic members preferably have equal elasticity. According to such a preferable example, it is possible to eliminate the possibility that an unintended swinging force is applied to the cam member due to the elasticity of the elastic member and the other elastic member, and it is possible to more appropriately rotate the rotating member. Can be given.

本発明の窓開閉装置の好ましい例では、案内路は、回動部材の回動に伴う枠体に対する揺動を案内するように枠体に設けられており、障子の他の部位は、障子の重心と同位置に配されている。このような好ましい例によれば、障子による開口の開閉において当該障子の自重に基づく開口開放位置に向かう移動力及び開口閉鎖位置に向かう移動力を生じさせることなく、付勢手段による障子の開口開放位置に向かうほぼ一定の移動力をもって障子を付勢することができる。   In a preferred example of the window opening and closing device of the present invention, the guide path is provided in the frame so as to guide the swinging with respect to the frame accompanying the rotation of the rotation member. It is placed at the same position as the center of gravity. According to such a preferable example, the opening and closing of the shoji by the urging means is not caused in the opening and closing of the opening by the shoji without generating the moving force toward the opening opening position based on the weight of the shoji and the moving force toward the opening closing position. The shoji can be urged with a substantially constant moving force toward the position.

It is connected via a cam member 136. The tension spring 133 may be arranged so that the turning force in the R1 direction with respect to the rotating arm 51 is maintained substantially constant when the shoji 4 is in the opening open position. May be disposed so that the rotational force is zero and the application of the rotational force is released.

カム部材１３６は、回動アーム５１の回動において回転軸心Ｃ１を中心として回転するように回動アーム５１の障子４側の端部に固着されている。カム部材１３６は、周面にカム面１３４及び１３５を有した板状のカム本体１５１と、ワイヤ１３７及び１３８の他端１５２及び１５３が装着される装着部１５４及び１５５を夫々有していると共に、ワイヤ１３７及び１３８をカム面１３４及び１３５に沿って案内することができるようにカム本体１５１を間にして互いに対向して当該カム本体１５１に取り付けられている板状の一対の案内部材１５６及び１５７とを具備している。カム本体１５１並びに案内部材１５６及び１５７の夫々の中心部には、部位３３に配設された軸体１５８が挿通される孔１５９が形成されている。カム部材１３６は、孔１５９において軸体１５８にブッシュ１７０を介して回転自在に装着される。   The cam member 136 is fixed to the end of the pivot arm 51 on the side of the shoji 4 so as to rotate about the rotation axis C1 when the pivot arm 51 rotates. The cam member 136 includes a plate-like cam body 151 having cam surfaces 134 and 135 on the peripheral surface, and mounting portions 154 and 155 to which the other ends 152 and 153 of the wires 137 and 138 are mounted, respectively. A pair of plate-like guide members 156 attached to the cam body 151 so as to be opposed to each other with the cam body 151 therebetween so that the wires 137 and 138 can be guided along the cam surfaces 134 and 135. 157. A hole 159 through which the shaft body 158 disposed in the portion 33 is inserted is formed at the center of each of the cam main body 151 and the guide members 156 and 157. The cam member 136 is rotatably attached to the shaft body 158 through the bush 170 in the hole 159.

カム本体１５１は、例えば図６の（ａ）及び（ｂ）に示すように、回転軸心Ｃ１を中心として回動する回動アーム５１の回動角と同角度θをもって回転軸心Ｃ１を中心として回転するように案内部材１５６を介して回動アーム５１に固着されている。カム本体１５１には、回転軸心Ｃ１及びＣ２を通る線４８と前記線４８に対して障子４の開口開放位置から開口閉鎖位置までの移動における回動アーム５１の回動角、即ち角度θをもって線４８に交わると共に回転軸心Ｃ１を通る線１６０との間に位置する周面の一方の部位、本例では周面の建物内８側の部位にカム面１３４が、線４８と線１６０との間に位置する周面の他方の部位、本例では周面の建物外７側の部位にカム面１３５が夫々形成されている。   For example, as shown in FIGS. 6A and 6B, the cam body 151 is centered on the rotation axis C1 with the same angle θ as the rotation angle of the rotation arm 51 that rotates about the rotation axis C1. Is fixed to the rotating arm 51 through a guide member 156 so as to rotate. The cam main body 151 has a rotation angle of the rotation arm 51 in the movement from the opening open position to the opening closing position of the shoji 4 with respect to the line 48 passing through the rotation axes C1 and C2 and the line 48, that is, the angle θ. A cam surface 134 is formed at one portion of the peripheral surface located between the line 48 and the line 160 passing through the rotation axis C1, in this example, at a portion of the peripheral surface on the side of the building 8. The cam surface 135 is formed in the other site | part of the surrounding surface located in between, the site | part of the outer surface 7 side of a surrounding surface in this example, respectively.

カム面１３４は湾曲形成されている。例えば図６の（ａ）及び（ｂ）並びに図９の（ａ）及び（ｂ）に示すように、線４８上に位置するカム面１３４の部位１６１は、線１６０上に位置するカム面１３４の部位１６２よりも回転軸心Ｃ１と同軸心であるカム本体１５１の回転軸心から離反している。部位１６１から回転軸心Ｃ１までの距離ｄ１は部位１６２から回転軸心Ｃ１までの距離ｄ２よりも長い。カム面１３４から回転軸心Ｃ１までの距離Ｄは、部位１６２から部位１６１に向かうに従って漸増している。斯かるカム面１３４は、回動アーム５１のＲ１方向の回動において当接端部１３９を回転軸心Ｃ１に対して漸次離反させる一方、回動アーム５１のＲ２方向の回動において当接端部１３９を回転軸心Ｃ１に対して漸次接近させるようになっている。   The cam surface 134 is curved. For example, as shown in FIGS. 6 (a) and 6 (b) and FIGS. 9 (a) and 9 (b), a portion 161 of the cam surface 134 located on the line 48 is a cam surface 134 located on the line 160. Is farther from the rotational axis of the cam body 151 which is coaxial with the rotational axis C1 than the portion 162 of FIG. The distance d1 from the part 161 to the rotation axis C1 is longer than the distance d2 from the part 162 to the rotation axis C1. The distance D from the cam surface 134 to the rotation axis C1 gradually increases from the portion 162 toward the portion 161. Such a cam surface 134 gradually separates the abutting end 139 from the rotation axis C1 when the rotating arm 51 rotates in the R1 direction, while the abutting end when the rotating arm 51 rotates in the R2 direction. The portion 139 is gradually brought closer to the rotation axis C1.

カム面１３５は湾曲形成されている。例えば図６の（ａ）及び（ｂ）並びに図９の（ａ）及び（ｂ）に示すように、線４８上に位置するカム面１３５の部位１６４は、線１６０上に位置するカム面１３５の部位１６５よりも回転軸心Ｃ１と同軸心であるカム本体１５１の回転軸心から離反している。部位１６４から回転軸心Ｃ１までの距離ｄ１は部位１６５から回転軸心Ｃ１までの距離ｄ２よりも長い。カム面１３５から回転軸心Ｃ１までの距離Ｄは、部位１６５から部位１６４に向かうに従って漸増している。斯かるカム面１３５は、回動アーム５１のＲ１方向の回動において当接端部１４０を回転軸心Ｃ１に対して漸次離反させる一方、回動アーム５１のＲ２方向の回動において当接端部１４０を回転軸心Ｃ１に対して漸次接近させるようになっている。カム面１３４及び１３５はカム本体１５１の回転軸心との関係において点対称である。   The cam surface 135 is curved. For example, as shown in FIGS. 6 (a) and 6 (b) and FIGS. 9 (a) and 9 (b), the portion 164 of the cam surface 135 located on the line 48 is the cam surface 135 located on the line 160. The portion 165 is farther away from the rotational axis of the cam body 151 that is coaxial with the rotational axis C1. The distance d1 from the part 164 to the rotation axis C1 is longer than the distance d2 from the part 165 to the rotation axis C1. The distance D from the cam surface 135 to the rotation axis C1 gradually increases from the part 165 toward the part 164. Such a cam surface 135 gradually separates the contact end 140 from the rotation axis C1 in the rotation of the rotation arm 51 in the R1 direction, while the contact end 140 in the rotation of the rotation arm 51 in the R2 direction. The portion 140 is gradually brought closer to the rotation axis C1. The cam surfaces 134 and 135 are point symmetric with respect to the rotational axis of the cam body 151.

案内部材１５６は、案内部材１５７に対して回動アーム５１側に配されて当該回動アーム５１の障子４側の端部に固着されている。案内部材１５７は、案内部材１５６に対して縦框２４側に配されている。横方向Ｙにおいて互いに対向して配される案内部材１５６及び１５７は、互いに同様に形成されているので、以下、案内部材１５６について詳細に説明し、案内部材１５７については図に適宜同符号を付してその詳細な説明を省略する。   The guide member 156 is disposed on the rotating arm 51 side with respect to the guide member 157 and is fixed to the end of the rotating arm 51 on the shoji 4 side. The guide member 157 is disposed on the vertical shaft 24 side with respect to the guide member 156.

案内部材１５６は、回転軸心Ｃ１と同軸心であるカム部材１３６の回転軸心に対して直交する方向においてカム面１３４及び１３５よりも突出している周縁の部位１７１及び１７２を具備している。斯かる部位１７１はカム面１３４に当接するワイヤ１３７の部位をカム面１３４に沿って案内し、部位１７２はカム面１３５に当接するワイヤ１３８の部位をカム面１３５に沿って案内する。部位１７１及び１７２は案内部材１５６の回転軸心との関係において点対称である。案内部材１５６の装着部１５４には、ワイヤ１３７の嵌合部１８３が嵌合する凹部１７３が形成されており、案内部材１５６の装着部１５５には、ワイヤ１３８の嵌合部１８４が嵌合する凹部１７４が形成されている。凹部１７３は、カム面１３４がワイヤ１３７の一端１４３及び他端１５２間に位置するように配設されており、凹部１７４は、カム面１３５がワイヤ１３８の一端１４６及び他端１５３間に配設されている。斯かる案内部材１５６は、カム本体１５１の回転とともに回転される。   The guide member 156 includes peripheral portions 171 and 172 that protrude from the cam surfaces 134 and 135 in a direction orthogonal to the rotation axis of the cam member 136 that is coaxial with the rotation axis C1. Such a portion 171 guides the portion of the wire 137 that contacts the cam surface 134 along the cam surface 134, and the portion 172 guides the portion of the wire 138 that contacts the cam surface 135 along the cam surface 135. The portions 171 and 172 are point symmetric with respect to the rotation axis of the guide member 156. A recessed portion 173 into which the fitting portion 183 of the wire 137 is fitted is formed in the mounting portion 154 of the guide member 156, and the fitting portion 184 of the wire 138 is fitted into the mounting portion 155 of the guide member 156. A recess 174 is formed. The recess 173 is disposed such that the cam surface 134 is positioned between the one end 143 and the other end 152 of the wire 137, and the recess 174 is disposed between the one end 146 and the other end 153 of the wire 138. Has been. Such a guide member 156 is rotated with the rotation of the cam body 151.

Columnar fitting portions 183 and 184 that fit into the recesses 173 and 174 of the guide members 156 and 157 are formed at the ends 152 and 153. The wire 137 abuts against the cam surface 134 with a wide area when the shoji 4 is in the open closed position, and the abutting end 139 located on the tension spring 132 side in the abutting area is the cam surface 134. The part 162 is contacted. The wire 137 abuts against the cam surface 134 with a narrow area when the shoji 4 is in the opening open position, and the abutting end 139 located on the tension spring 132 side in the abutting area is the cam surface 134. It contacts the part 161. The wire 138 abuts against the cam surface 135 with a wide area when the shoji 4 is in the open closed position, and the abutting end 140 located on the tension spring 133 side in the abutting area is the cam surface 135.

When the shoji 4 is in the opening open position, the wire 138 contacts the cam surface 135 with a narrow region, and the contact end 140 located on the tension spring 133 side in the contact region is the cam surface 135. It contacts the part 164.

引張ばね１３２及び１３３、ワイヤ１３７及び１３８並びにカム面１３４及び１３５は、引張ばね１３２がワイヤ１３７及びカム部材１３６を介して回動アーム５１に対して付与するＲ１方向の回動力と引張ばね１３３がワイヤ１３８及びカム部材１３６を介して回動アーム５１に対して付与するＲ１方向の回動力とが互いに等しくなるように、回転軸心Ｃ１との関係において点対称に夫々形成、配置されている。   The tension springs 132 and 133, the wires 137 and 138, and the cam surfaces 134 and 135 include the rotational force in the R1 direction that the tension spring 132 applies to the rotating arm 51 via the wire 137 and the cam member 136, and the tension spring 133. They are formed and arranged symmetrically with respect to the rotational axis C1 so that the rotational forces in the R1 direction applied to the rotating arm 51 via the wire 138 and the cam member 136 are equal to each other.

斯かる付勢手段５によれば、引張ばね１３２及び１３３の引張力に基づいて回動アーム５１にＲ１方向の回動力を付与することで、障子４を開口開放位置に向かって付勢することができ、しかも、回動アーム５１のＲ１方向の回動においてワイヤ１３７及び１３８のカム面１３４及び１３５に対する当接端部１３９及び１４０を回転軸心Ｃ１から漸次離反させることで、回動アーム５１のＲ１方向の回動において漸減する引張ばね１３２及び１３３の引張力に基づいて当該回動アーム５１に殆ど減少されないほぼ一定のＲ１方向の回動力を付与することができ、而して、障子４を開口開放位置に向かうほぼ一定の移動力をもって付勢することができる。また、斯かる付勢手段５によれば、障子４の開口閉鎖位置に向かう移動において当接端部１３９及び１４０が回転軸心Ｃ１に漸次近接するので、回動アーム５１のＲ２方向の回動において漸増する引張ばね１３２及び１３３の引張力に基づいて当該回動アーム５１に殆ど増大されないほぼ一定のＲ２方向の回動力を付与することができ、而して、障子４が開口閉鎖位置に向かう移動に抗するほぼ一定の抗移動力を障子４に対して生じさせ得る。   According to the urging means 5, the shoji 4 is urged toward the opening opening position by applying a turning force in the R1 direction to the rotating arm 51 based on the tensile force of the tension springs 132 and 133. In addition, when the rotating arm 51 rotates in the R1 direction, the abutting ends 139 and 140 of the wires 137 and 138 with respect to the cam surfaces 134 and 135 are gradually separated from the rotation axis C1, thereby rotating the rotating arm 51. Based on the tensile force of the tension springs 132 and 133 that gradually decrease in the rotation in the R1 direction, a substantially constant turning force in the R1 direction that is hardly reduced can be applied to the rotation arm 51. Can be urged with a substantially constant moving force toward the opening opening position. Further, according to the biasing means 5, since the contact end portions 139 and 140 gradually approach the rotation axis C <b> 1 in the movement of the shoji 4 toward the opening closed position, the rotation arm 51 rotates in the R <b> 2 direction. Can be applied to the rotating arm 51 based on the tensile force of the tension springs 132 and 133 that gradually increase at the same time, so that a substantially constant turning force in the R2 direction can be applied to the pivot arm 51. An almost constant anti-movement force against movement can be generated for the shoji 4.

尚、付勢手段５は、引張ばね１３２に代えて、例えば、ワイヤ１３７及びカム部材１３６を夫々介して回動アーム５１にＲ１方向の回動力を付与する圧縮ばね（図示せず）を具備していてもよく、斯かる場合には、ワイヤ１３７の一端１４３は、当該圧縮ばねの縦框２４に装着された不動端に対して上框２２側に位置する可動端に連結されてもよい。また、付勢手段５は、引張ばね１３３に代えて、前記同様の圧縮ばねを具備していてもよい。加えて、付勢手段５の弾性部材は、本例では捩りばねからなるが、これに代えて、例えば空気圧若しくは油圧シリンダ等からなっていてもよい。   Note that the biasing means 5 includes a compression spring (not shown) that applies a rotational force in the R1 direction to the rotating arm 51 via, for example, a wire 137 and a cam member 136, instead of the tension spring 132. In such a case, one end 143 of the wire 137 may be coupled to a movable end located on the upper collar 22 side with respect to the stationary end mounted on the vertical collar 24 of the compression spring. Further, the urging means 5 may include a compression spring similar to the above, instead of the tension spring 133. In addition, the elastic member of the urging means 5 is composed of a torsion spring in this example, but may instead be composed of, for example, a pneumatic or hydraulic cylinder.

窓開閉装置１は、開閉手段５による障子４の開口開放位置に向かう移動を解除自在に禁止するように、開口閉鎖位置にある障子４を窓枠２に係止する係止部材（図示せず）を更に具備している。斯かる係止部材は、障子４が開口閉鎖位置にある場合に操作により回転されて窓枠２、例えば下枠１３に係止される一方、操作により逆回転されて下枠１３への係止が解除されるように、例えば障子４の下框２３に回転自在に取り付けられていてもよい。   The window opening and closing device 1 is a locking member (not shown) for locking the shoji 4 in the opening closed position to the window frame 2 so as to releasably inhibit the movement of the shoji 4 toward the opening opening position by the opening and closing means 5. ). Such a locking member is rotated by the operation when the shoji 4 is in the open closed position and locked to the window frame 2, for example, the lower frame 13, while being reversely rotated by the operation to lock the lower frame 13. For example, it may be rotatably attached to the lower arm 23 of the shoji 4 so as to be released.

以上の窓開閉装置１による窓開閉操作について以下説明する。まず、操作により係止部材による障子４の窓枠２への係止を解除する。当該係止が解除されると、引張ばね１３２及び１３３の弾性に基づいてＲ１方向の回動力が与えられている回動アーム５１が回転軸心Ｃ１を中心としてＲ１方向に回動し、この回動により開口閉鎖位置にある障子４には移動力Ａが与えられ、而して、開口閉鎖位置にある障子４は、付勢手段５による付勢によって開口開放位置に向かって移動される。回動アーム５１の前記Ｒ１方向の回動において当該回動アーム５１の窓枠２側の端部は、案内路７１に案内されながら上方に向かって直動し、連結アーム６１は回動アーム５１の前記Ｒ１方向の回動に基づいて回転軸心Ｃ４を中心としてｒ１方向に回動する。このようにＲ１方向に回動する回動アーム５１の障子４側の端部における回転軸心Ｃ１は、建物内外方向Ｘにおいて建物内８から建物外７に向かって近似平行運動、本例では厳正直線運動を行い、これにより、部位３３もまた建物内外方向Ｘにおいて建物内８から建物外７に向かって移動される。障子４が開口閉鎖位置にある場合においては、引張ばね１３２及び１３３の弾性に基づく図６の（ａ）に示す引張力Ｂは大きいが、当接端部１３９及び１４０から回転軸心Ｃ１までの図６の（ｂ）に示す距離は最も短い距離ｄ２となっているので、引張ばね１３２及び１３３の引張力Ｂは、減殺されて回動アーム５１に伝達される。   The window opening / closing operation by the above window opening / closing device 1 will be described below. First, the locking of the shoji 4 to the window frame 2 by the locking member is released by the operation. When the locking is released, the turning arm 51 to which the turning force in the R1 direction is applied based on the elasticity of the tension springs 132 and 133 turns around the rotation axis C1 in the R1 direction. The movement force A is given to the shoji 4 in the opening closed position by the movement, and thus the shoji 4 in the opening closing position is moved toward the opening opening position by the biasing means 5. When the rotating arm 51 rotates in the R1 direction, the end of the rotating arm 51 on the side of the window frame 2 moves straight upward while being guided by the guide path 71, and the connecting arm 61 is rotated. Based on the rotation in the R1 direction, the rotation is performed in the r1 direction around the rotation axis C4. Thus, the rotation axis C1 at the end on the side of the shoji 4 of the rotating arm 51 that rotates in the R1 direction is an approximate parallel movement from the inside 8 to the outside 7 in the inside / outside direction X of the building, which is strictly in this example. By performing a linear motion, the portion 33 is also moved from the inside 8 to the outside 7 in the inside / outside direction X of the building. When the shoji 4 is in the open closed position, the tensile force B shown in FIG. 6A based on the elasticity of the tension springs 132 and 133 is large, but from the contact end portions 139 and 140 to the rotation axis C1. Since the distance shown in FIG. 6B is the shortest distance d2, the tensile force B of the tension springs 132 and 133 is reduced and transmitted to the rotating arm 51.

上述のように付勢手段５により付勢され、開口開放位置に向かって移動される障子４は、図７に示す位置を経て開口開放位置まで移動される。斯かる障子４の移動に伴い、引張ばね１３２及び１３３の引張量が漸減して引張力Ｂも漸次小さくなるが、当接端部１３９及び１４０から回転軸心Ｃ１までの距離（距離Ｄと等しい距離である）は漸増するので、引張ばね１３２及び１３３の引張力Ｂに基づいて回動アーム５１に対して与えるＲ１方向の回動力は殆ど減少されることなく、障子４が開口閉鎖位置にある場合において回動アーム５１に対して与えられるＲ１方向の回動力とほぼ同等である。   The shoji 4 urged by the urging means 5 as described above and moved toward the opening opening position is moved to the opening opening position through the position shown in FIG. As the shoji 4 moves, the tension amount of the tension springs 132 and 133 gradually decreases and the tension force B gradually decreases, but the distance from the contact end portions 139 and 140 to the rotation axis C1 (equal to the distance D). (The distance) gradually increases, so that the rotational force in the R1 direction applied to the rotating arm 51 based on the tensile force B of the tension springs 132 and 133 is hardly reduced, and the shoji 4 is in the open closed position. In this case, the rotational force in the R1 direction given to the rotating arm 51 is almost the same.

開口開放位置に向かう移動によって障子４が開口開放位置に到達すると、引張ばね１３２及び１３３の引張量は、本例ではゼロとなるために、引張ばね１３２及び１３３の図９の（ａ）に示す引張力Ｂに基づく回動アーム５１に対するＲ１方向の回動力も生じなくなり、回動アーム５１から部位３３に対して与えられる移動力Ａも生じなくなるので、障子４は、開口開放位置において静止する。障子４が開口開放位置にある場合には、当接端部１３９及び１４０から回転軸心Ｃ１までの距離は最も長い距離ｄ１となる。障子４が開口開放位置にある場合においても、回転軸心Ｃ２は回転軸心Ｃ１に対して下方に位置している。尚、案内路７１の上端が、障子４が開口開放位置に到達した際に軸体７２に当接して当該端部の更なる上方への直動を禁止するようになっている場合には、軸体７２の上方への直動の禁止によって障子４の開口開放位置に向かう移動も禁止されるので、引張ばね１３２及び１３３は、障子４が開口開放位置に到達した場合においても引張力Ｂが残存するように配設されていてもよい。   When the shoji 4 reaches the opening opening position by moving toward the opening opening position, the tension amount of the tension springs 132 and 133 becomes zero in this example, so that the tension springs 132 and 133 are shown in FIG. The rotational force in the R1 direction with respect to the rotating arm 51 based on the tensile force B is not generated, and the moving force A applied to the portion 33 from the rotating arm 51 is also not generated, so that the shoji 4 is stationary at the opening open position. When the shoji 4 is in the opening open position, the distance from the contact end portions 139 and 140 to the rotation axis C1 is the longest distance d1. Even when the shoji 4 is in the opening open position, the rotation axis C2 is located below the rotation axis C1. In addition, when the upper end of the guide path 71 comes into contact with the shaft body 72 when the shoji 4 reaches the opening opening position and prohibits further linear movement of the end portion, Since the movement of the shoji 4 toward the opening opening position is prohibited by the prohibition of the linear movement upward of the shaft body 72, the tension springs 132 and 133 have a tensile force B even when the shoji 4 reaches the opening opening position. You may arrange | position so that it may remain | survive.

障子４が開口開放位置にある場合において、気流に基づき障子４よりも建物外７側が正圧に且つ障子４よりも建物内８側が負圧になると、障子４には気流に基づいて開口閉鎖位置に向かう移動力が付与される。この気流に基づく前記移動力によって障子４が開口閉鎖位置に向かって移動すると、建物外７及び建物内８間を流れる気体流量は減少する。気流に基づいて障子４に付与される開口閉鎖位置に向かう移動は、当該気流に基づく開口閉鎖位置に向かう移動力が引張ばね１３２及び１３３の弾性に基づいて回動アーム５１から障子４に与えられるほぼ一定の移動力Ａを上回った場合に生じる。回動アーム５１の障子４に対する移動力Ａはほぼ一定であり、障子４が開口閉鎖位置に向かって移動されても殆ど増大されないので、気流に基づく開口閉鎖位置に向かう移動力が付与される障子４は、当該移動力に基づいて速やかに開口閉鎖位置に向かって移動し得、而して、建物外７から建物内８に向かう強風の開口３における吹き抜けを防止し得る。逆に、気流により障子４よりも建物外７側が負圧に且つ障子４よりも建物内８側が正圧になると、障子４には開口開放位置に向かう移動力が付与される。この気流に基づく開口開放位置に向かう移動力によって障子４が開口開放位置に向かって移動すると、建物外７及び建物内８間を流れる気体流量は増大する。気流に基づく開口開放位置に向かう移動力及び開口閉鎖位置に向かう移動力が障子４に対して生じなくなると、障子４は付勢手段５によって付勢され、開口開放位置に復帰し、静止する。   When the shoji 4 is in the opening open position, if the outside 7 side of the building 7 is more positive than the shoji 4 and the inside 8 of the building is more negative than the shoji 4 based on the airflow, A moving force toward is provided. When the shoji 4 moves toward the opening closed position by the moving force based on the air flow, the flow rate of the gas flowing between the outside 7 and the inside 8 of the building decreases. In the movement toward the opening closed position given to the shoji 4 based on the air flow, the moving force toward the opening closing position based on the air flow is given from the rotating arm 51 to the shoji 4 based on the elasticity of the tension springs 132 and 133. Occurs when a substantially constant moving force A is exceeded. The moving force A of the rotating arm 51 with respect to the shoji 4 is substantially constant, and even if the shoji 4 is moved toward the opening closed position, the moving force A is hardly increased. 4 can quickly move toward the opening closed position based on the moving force, and thus can prevent the strong wind opening 3 from the outside 7 of the building to the inside 8 of the building. On the other hand, when the air flow causes negative pressure on the outside 7 side of the shoji 4 and positive pressure on the inside 8 side of the shoji 4, a moving force toward the opening opening position is applied to the shoji 4. When the shoji 4 moves toward the opening opening position by the moving force toward the opening opening position based on the air flow, the flow rate of the gas flowing between the outside 7 and the inside 8 of the building increases. When the moving force toward the opening opening position based on the airflow and the moving force toward the opening closing position are not generated on the shoji 4, the shoji 4 is urged by the urging means 5, returns to the opening opening position, and stops.

開口開放位置にある障子４が操作により開口閉鎖位置に向かって移動された場合においては、回動アーム５１はＲ１方向とは逆のＲ２方向に回動し、この回動により軸体７２は案内路７１に案内されながら下方に直動される。連結アーム６１は回動アーム５１のＲ２方向の回動に伴ってｒ１方向とは逆のｒ２方向に回動する。このように回動アーム５１がＲ２方向に回動すると、回転軸心Ｃ１は建物内外方向Ｘにおいて建物外７から建物内８に向かって近似平行運動、本例では厳正直線運動を行い、これにより、部位３３もまた建物内外方向Ｘにおいて建物外７から建物内８に向かって厳正直線運動を行う。引張ばね１３２及び１３３は、上述のように回動アーム５１がＲ２方向に回動されると引張されるので当該回動アーム５１に対してＲ１方向の回動力を与えるが、斯かるＲ１方向の回動力はほぼ一定であるので、障子４を操作により開口閉鎖位置に向かって容易に移動させることができる。操作により開口閉鎖位置まで移動された障子４は、係止部材によって窓枠２に係止されることによって開口３の全閉状態を維持する。尚、気流に基づく障子４の開口閉鎖位置に向かう移動に抗する抗力は、気流に基づく回動アーム５１のＲ２方向の回動において変化する回動アーム５１の回動角の関係で漸減する軸体７２の案内路７１に対する抵抗力と付勢手段５による回動アーム５１に対するほぼ一定のＲ１方向の回動力の付与の関係で漸増する軸体７２の案内路７１に対する抵抗力との釣り合いによっても、一定に近づけ得る。   When the shoji 4 in the opening opening position is moved toward the opening closing position by the operation, the rotating arm 51 rotates in the R2 direction opposite to the R1 direction, and the shaft 72 is guided by this rotation. While being guided by the path 71, it is directly moved downward. The connecting arm 61 rotates in the r2 direction opposite to the r1 direction as the rotating arm 51 rotates in the R2 direction. When the rotating arm 51 rotates in the R2 direction in this way, the rotation axis C1 performs an approximate parallel movement from the outside of the building 7 to the inside 8 of the building in the inside / outside direction X, in this example, a strictly straight line movement. The part 33 also performs a strict linear motion from the outside 7 to the inside 8 in the inside / outside direction X of the building. As described above, the tension springs 132 and 133 are pulled when the rotating arm 51 is rotated in the R2 direction, and thus provide the rotational force in the R1 direction to the rotating arm 51. Since the rotational force is substantially constant, the shoji 4 can be easily moved toward the opening closed position by operation. The shoji 4 that has been moved to the opening closed position by the operation is locked to the window frame 2 by the locking member, thereby maintaining the fully closed state of the opening 3. The drag force that resists the movement of the shoji 4 toward the opening closed position based on the airflow is an axis that gradually decreases due to the rotation angle of the rotation arm 51 that changes in the rotation of the rotation arm 51 in the R2 direction based on the airflow. Also by the balance between the resistance force of the body 72 to the guide path 71 and the resistance force of the shaft body 72 to the guide path 71 that gradually increases due to the application of a substantially constant rotational force in the R1 direction to the rotating arm 51 by the biasing means 5. , Can be close to constant.

本例の窓開閉装置１によれば、建物に装着される窓枠２と、窓枠２に画成された開口３に配されていると共に当該開口３を開閉する障子４と、障子４が気流に基づいて開口３を開閉自在となるように、障子４の鉛直方向Ｖにおける一方側の部位３１を窓枠２に対して回転自在に連結している連結手段３２と、障子４を開口開放位置に向かって付勢すべく障子４及び窓枠２に連結されている付勢手段５とを具備しており、付勢手段５は、障子４の部位３１に対して鉛直方向Ｖにおいて異なる位置に存する他の部位３３及び当該部位３３に対して鉛直方向Ｖにおいて異なる位置に存する窓枠２の部位１５の夫々に回転自在に連結されていると共に回動により部位３３に対して建物内８側から建物外７側に向かう移動力Ａを付与する回動アーム５１と、障子４及び窓枠２のうちの一方としての窓枠２に設けられていると共に回動アーム５１の回動に伴う窓枠２に対する揺動、本例では直動を案内する案内路７１と、障子４及び窓枠２のうちの他方としての障子４に装着されている弾性部材としての引張ばね１３２と、回動アーム５１に固着されていると共にカム面１３４を有したカム部材１３６と、引張ばね１３２とカム部材１３６とを連結していると共に、引張ばね１３２の弾性により部位３３に対して移動力Ａを付与するためのＲ１方向の回動力をカム部材１３６を介して回動アーム５１に与えられるようにカム面１３４に当接する可撓性を有した可撓体としてのワイヤ１３７とを具備しており、カム面１３４は、当該カム面１３４に当接するワイヤ１３７の引張ばね１３２側における当接端部１３９が部位３３に対して移動力Ａを付与するための回動アーム５１のＲ１方向の回動において当該回動アーム５１の障子４及び窓枠２のうちの他方としての障子４に対する回転軸心Ｃ１から漸次離反するように形成されているために、障子４による開口３の開閉に伴う引張ばね１３２の引張量の変化に基づく回動アーム５１に対する回動力の変化を減少させることができ、而して、障子４の開口開放位置に向かう移動力を一定に近づけることができる。   According to the window opening and closing device 1 of the present example, the window frame 2 attached to the building, the shoji 4 disposed in the window frame 2 and opening and closing the opening 3, and the shoji 4 are provided. A connecting means 32 that rotatably connects one side 31 in the vertical direction V of the shoji 4 to the window frame 2 so that the opening 3 can be opened and closed based on the air current, and the shoji 4 is opened. And a biasing means 5 connected to the window frame 2 for biasing toward the position. The biasing means 5 is different in the vertical direction V with respect to the part 31 of the shoji 4. The other part 33 existing in the window 33 and the part 15 of the window frame 2 existing at different positions in the vertical direction V with respect to the part 33 are rotatably connected to the part 33 and turned to the part 33 by the rotation. Rotating arm 51 for applying a moving force A toward the outside 7 side of the building And a guide path 71 that is provided on the window frame 2 as one of the shoji 4 and the window frame 2 and that guides swinging with respect to the window frame 2 as the rotating arm 51 rotates, in this example, linear motion. A tension spring 132 as an elastic member attached to the shoji 4 as the other of the shoji 4 and the window frame 2, a cam member 136 fixed to the rotating arm 51 and having a cam surface 134; The tension spring 132 and the cam member 136 are connected to each other, and the rotational arm 51 in the R1 direction for applying the moving force A to the portion 33 by the elasticity of the tension spring 132 is provided via the cam member 136. And a wire 137 as a flexible body that comes into contact with the cam surface 134, and the cam surface 134 is a tension spring 132 side of the wire 137 that comes into contact with the cam surface 134. In The shoji 4 as the other of the shoji 4 and the window frame 2 of the pivot arm 51 in the pivoting of the pivot arm 51 in the R1 direction for the contact end 139 to apply the moving force A to the portion 33. Since the rotation axis C1 is gradually separated from the rotation axis C1, the change in the rotational force with respect to the rotating arm 51 based on the change in the tensile amount of the tension spring 132 accompanying the opening and closing of the opening 3 by the shoji 4 is reduced. Thus, the moving force of the shoji 4 toward the opening opening position can be made close to a constant value.

窓開閉装置１によれば、弾性部材は、障子４の開口開放位置に向かう移動において引張量が漸減するように障子４及び窓枠２のうちの他方としての障子４に装着された引張ばね１３２からなるために、障子４の開口開放位置に向かう移動における引張ばね１３２の引張量の漸減に応じて、カム面１３４に当接するワイヤ１３７の引張ばね１３２側における当接端部１３９を部位３３に対して建物内８側から建物外７側に向かう移動力Ａを付与するための回動アーム５１のＲ１方向の回動において回転軸心Ｃ１から漸次離反させることができ、而して、障子４の開口開放位置に向かう移動力を一定に近づけることができる。   According to the window opening / closing apparatus 1, the elastic member is attached to the shoji 4 as the other of the shoji 4 and the window frame 2 so that the amount of tension gradually decreases when the shoji 4 moves toward the opening opening position. Therefore, the contact end portion 139 of the wire 137 that contacts the cam surface 134 on the side of the tension spring 132 is moved to the region 33 in accordance with the gradual decrease of the tension amount of the tension spring 132 in the movement of the shoji 4 toward the opening opening position. On the other hand, in the rotation in the R1 direction of the rotating arm 51 for applying the moving force A from the inside 8 side to the outside 7 side, the sliding arm 4 can be gradually separated from the rotation axis C1. The moving force toward the opening opening position can be made closer to a certain level.

窓開閉装置１によれば、カム部材１３６は、他のカム面１３５を有しており、付勢手段５は、障子４及び窓枠２のうちの他方としての障子４に装着されている他の弾性部材としての引張ばね１３３と、引張ばね１３３とカム部材１３６とを連結していると共に、引張ばね１３３の弾性により部位３３に対して移動力Ａを付与するためのＲ１方向の回動力をカム部材１３６を介して回動アーム５１に与えられるようにカム面１３５に当接する可撓性を有した他の可撓体としてのワイヤ１３８とを具備しており、カム面１３５は、当該カム面１３５に当接するワイヤ１３８の引張ばね１３３側における当接端部１４０が部位３３に対して移動力Ａを付与するための回動アーム５１のＲ１方向の回動において回転軸心Ｃ１から漸次離反するように形成されているために、引張ばね１３２の弾性に基づく回動アーム５１に対するほぼ一定のＲ１方向の回動力の付与に加えて、引張ばね１３３の弾性に基づく回動アーム５１に対するほぼ一定のＲ１方向の回動力をも当該回動アーム５１に付与することができ、しかも、例えばワイヤ１３７及び１３８のうちの一方の意図しない切断等により引張ばね１３２及び１３３のうちの一方の弾性に基づいて回動アーム５１に対してＲ１方向の回動力を付与することができなくなった場合においても、引張ばね１３２及び１３３のうちの他方の弾性に基づいて回動アーム５１に対してＲ１方向の回動力を付与することができ、而して、付勢手段５に意図しない支障が生じた際にも障子４の急速な開口閉鎖位置に向かう移動を阻止し得る。   According to the window opening / closing device 1, the cam member 136 has another cam surface 135, and the biasing means 5 is mounted on the shoji 4 as the other of the shoji 4 and the window frame 2. The tension spring 133 as an elastic member, the tension spring 133 and the cam member 136 are connected, and the rotational force in the R1 direction for applying the moving force A to the portion 33 by the elasticity of the tension spring 133 is provided. And a wire 138 as another flexible body having flexibility to come into contact with the cam surface 135 so as to be given to the rotating arm 51 via the cam member 136, and the cam surface 135 is connected to the cam surface 135. The abutting end 140 on the tension spring 133 side of the wire 138 that abuts the surface 135 gradually separates from the rotation axis C1 in the rotation of the rotation arm 51 in the R1 direction for applying the moving force A to the portion 33. Shape to do Therefore, in addition to the application of the substantially constant rotational force in the R1 direction to the rotating arm 51 based on the elasticity of the tension spring 132, the substantially constant R1 direction in the rotating arm 51 based on the elasticity of the tension spring 133 is provided. Rotational power can also be applied to the rotating arm 51, and the rotating arm can be based on the elasticity of one of the tension springs 132 and 133 by unintentional cutting of one of the wires 137 and 138, for example. Even when it becomes impossible to apply the rotational force in the R1 direction to 51, the rotational force in the R1 direction is applied to the rotating arm 51 based on the elasticity of the other of the tension springs 132 and 133. Therefore, even when an unintended trouble occurs in the biasing means 5, the movement of the shoji 4 toward the rapid opening closed position can be prevented.

窓開閉装置１によれば、カム部材１３６は、回動アーム５１の回動において回転軸心Ｃ１を中心として回転するように回動アーム５１に固着されており、引張ばね１３２、カム面１３４及びワイヤ１３７並びに引張ばね１３３、カム面１３５及びワイヤ１３８は、回転軸心Ｃ１との関係において点対称となるように夫々配されているために、引張ばね１３２及び１３３の弾性によりカム部材１３６に対して意図しない揺動力を与える虞をなくすことができて、回動アーム５１に対してより好適に回動力を与えることができる。尚、引張ばね１３２及び１３３は、好ましくは互いに等しい弾性を有している。   According to the window opening / closing device 1, the cam member 136 is fixed to the rotating arm 51 so as to rotate about the rotation axis C1 when the rotating arm 51 rotates, and the tension spring 132, the cam surface 134, and the like. Since the wire 137, the tension spring 133, the cam surface 135, and the wire 138 are arranged so as to be point symmetric with respect to the rotation axis C1, the elasticity of the tension springs 132 and 133 causes the cam member 136 to be elastic. Therefore, it is possible to eliminate the possibility of giving unintentional swinging force, and it is possible to more suitably apply rotational force to the rotating arm 51. The tension springs 132 and 133 preferably have the same elasticity.

窓開閉装置１によれば、案内路７１は、回動アーム５１の回動に伴う窓枠２に対する直動を案内するように窓枠２に設けられており、部位３３は、障子４の重心Ｇと同位置に配されているために、障子４による開口３の開閉において当該障子４の自重に基づく開口開放位置に向かう移動力及び開口閉鎖位置に向かう移動力を生じさせることなく、付勢手段５による障子４の開口開放位置に向かうほぼ一定の移動力Ａをもって障子４を付勢することができる。   According to the window opening and closing device 1, the guide path 71 is provided in the window frame 2 so as to guide the linear movement with respect to the window frame 2 accompanying the rotation of the rotation arm 51, and the portion 33 is provided with the center of gravity of the shoji 4. Since it is arranged at the same position as G, the opening and closing of the opening 3 by the shoji 4 is energized without generating a moving force toward the opening opening position and a moving force toward the opening closing position based on the dead weight of the shoji 4. The shoji 4 can be urged with a substantially constant moving force A toward the opening opening position of the shoji 4 by the means 5.

窓開閉装置１によれば、付勢手段５は、回動アーム５１の回転軸心Ｃ１及びＣ２間の部位５２及び当該部位５２に対して鉛直方向Ｖにおいて回転軸心Ｃ１側に位置する窓枠２の部位１６の夫々に回転自在に連結されている連結アーム６１を具備しており、案内路７１は、回転軸心Ｃ２を、当該回転軸心Ｃ２と連結アーム６１の窓枠２に対する回転軸心Ｃ４とを通る鉛直方向Ｖに伸びる線上において直動自在に案内するように窓枠２に設けられており、連結手段３２は、部位３１を窓枠２に対して昇降自在に連結しており、連結アーム６１の回動アーム５１に対する回転軸心Ｃ３から回転軸心Ｃ４までの長さＬ１と回転軸心Ｃ２から回転軸心Ｃ３までの長さＬ２との比は、長さＬ２と回転軸心Ｃ１から回転軸心Ｃ３までの長さＬ３との比に対して等しくなっているために、障子４による開口３の開閉において部位３３にいわゆる近似平行運動を行わせることができる。また、窓開閉装置１によれば、長さＬ２は、長さＬ３と等しくなっているために、障子４による開口３の開閉において当該部位３３に厳正直線運動を行わせ得る。   According to the window opening and closing device 1, the biasing means 5 is a window frame located on the side of the rotation axis C <b> 1 in the vertical direction V with respect to the part 52 between the rotation axes C <b> 1 and C <b> 2 of the rotation arm 51 and the part 52. The guide path 71 includes a rotation axis C2 and a rotation axis of the rotation axis C2 and the connection arm 61 with respect to the window frame 2. It is provided in the window frame 2 so as to be guided linearly on a line extending in the vertical direction V passing through the center C4, and the connecting means 32 connects the portion 31 to the window frame 2 so as to be movable up and down. The ratio of the length L1 from the rotation axis C3 to the rotation axis C4 to the rotation axis 51 of the connecting arm 61 and the length L2 from the rotation axis C2 to the rotation axis C3 is the length L2 and the rotation axis. For the ratio of the length L3 from the center C1 to the rotation axis C3 To are equal, it is possible to perform the so-called approximate translational motion in a portion 33 in the opening and closing of the opening 3 by shoji 4. Further, according to the window opening / closing device 1, since the length L2 is equal to the length L3, the portion 33 can be caused to perform a strict linear motion in opening / closing the opening 3 by the shoji 4.

窓開閉装置１によれば、連結手段３２は、障子４の上側の部位３１を窓枠２に対して回転自在に且つ昇降自在に連結しており、回動アーム５１は、部位３１に対して下方に位置する部位３３に回転自在に連結されており、回転軸心Ｃ２は、回転軸心Ｃ１に対して下方に配されており、回転軸心Ｃ４は、回転軸心Ｃ２に対して上方に配されているために、例えば連結手段３２と付勢手段５とを互いに近接して配置した場合においても、障子４による開口３の開閉において付勢手段５が連結手段３２に干渉する虞をなくし得て、連結手段３２及び付勢手段５の夫々の配置の自由度を向上させることができ、種々の寸法の障子４を窓枠２に連結し得る。   According to the window opening / closing device 1, the connecting means 32 connects the upper part 31 of the shoji 4 to the window frame 2 so as to be rotatable and liftable, and the rotating arm 51 is connected to the part 31. The rotary shaft C2 is rotatably connected to the lower portion 33. The rotation axis C2 is arranged below the rotation axis C1, and the rotation axis C4 is located above the rotation axis C2. For example, even when the connecting means 32 and the biasing means 5 are arranged close to each other, the biasing means 5 can be prevented from interfering with the connecting means 32 when the opening 3 is opened and closed by the shoji 4. Thus, the degree of freedom of the arrangement of the connecting means 32 and the biasing means 5 can be improved, and the shoji 4 having various dimensions can be connected to the window frame 2.

図１０から図１６において、本例の窓開閉装置８０は、窓開閉装置１と同様の構成を具備しており、これらに加えて、減衰機構８１を更に具備している。窓開閉装置８０の窓開閉装置１と同様の構成を具備しているので、当該各構成については図に適宜同符号を付してこれらの詳細な説明を省略する。   10 to 16, the window opening / closing device 80 of this example has the same configuration as the window opening / closing device 1, and further includes a damping mechanism 81. Since the window opening / closing device 80 has the same configuration as that of the window opening / closing device 1, the same reference numerals are given to the respective components, and the detailed description thereof will be omitted.

開口閉鎖位置の近傍に位置する障子４の図１０に示す開口閉鎖位置に向かう移動を減衰する減衰機構８１は、例えば図１０から図１４に示すように、回転体８２を有していると共に当該回転体８２の一方向としてのＲ３方向の回転に基づいて開口閉鎖位置の近傍に位置する障子４の当該開口開放位置に向かう移動において生じる回動アーム５１の窓枠２に対する直動を減衰するための抵抗力を生じる一方向ダンパ８３と、回転体８２に当接した状態における一方向ダンパ８３に対する相対的な移動により当該回転体８２を一方向に回転させる当接部材８４とを具備しており、一方向ダンパ８３及び当接部材８４のうちの一方としての一方向ダンパ８３は、回動アーム５１の前記直動に基づいて、一方向ダンパ８３及び当接部材８４の他方としての当接部材８４に対する前記相対的な移動を生じるようになっている。本例では、一方向ダンパ８３は、窓枠２に案内路７１に沿って直動自在に装着されており、当接部材８４は窓枠２に固着されている。   A damping mechanism 81 for attenuating the movement of the shoji 4 located in the vicinity of the opening closing position toward the opening closing position shown in FIG. 10 has a rotating body 82 as shown in FIGS. 10 to 14, for example. In order to attenuate the direct movement of the rotary arm 51 with respect to the window frame 2 that occurs in the movement of the shoji 4 located in the vicinity of the opening closed position toward the opening opening position based on the rotation in the R3 direction as one direction of the rotating body 82. And a contact member 84 that rotates the rotating body 82 in one direction by relative movement with respect to the one-way damper 83 in a state of being in contact with the rotating body 82. The one-way damper 83 as one of the one-way damper 83 and the contact member 84 is the other of the one-way damper 83 and the contact member 84 based on the linear movement of the rotating arm 51. So that the resulting said relative movement with respect to the abutting member 84. In this example, the one-way damper 83 is mounted on the window frame 2 so as to be movable along the guide path 71, and the contact member 84 is fixed to the window frame 2.

減衰機構８１は、上述の構成に加えて、一方向ダンパ８３及び当接部材８４が互いに相対的に移動した場合において、一方向ダンパ８３を当接部材８４に対する初期位置に復帰させるように付勢する付勢部材８５と、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動において窓枠２に対して直動する回動アーム５１の部位、本例では回動アーム５１の窓枠２側の端部に装着されていると共に、回動アーム５１の前記直動を一方向ダンパ８３に伝達するように当該一方向ダンパ８３に当接する伝達部材８６とを具備している。減衰機構８１は、回動アーム５１、連結アーム６１及び案内路７１を付製手段５と共有している。   In addition to the above-described configuration, the damping mechanism 81 urges the unidirectional damper 83 to return to the initial position with respect to the abutting member 84 when the unidirectional damper 83 and the abutting member 84 move relative to each other. A portion of the rotating arm 51 that moves directly with respect to the window frame 2 in the movement toward the opening closed position of the shoji 4 positioned near the opening closing position, in this example, the rotation arm 51 A transmission member 86 that is attached to an end portion on the window frame 2 side and abuts against the one-way damper 83 so as to transmit the linear movement of the rotating arm 51 to the one-way damper 83 is provided. The damping mechanism 81 shares the rotating arm 51, the connecting arm 61, and the guide path 71 with the manufacturing means 5.

一方向ダンパ８３は、例えば図１１から図１４に示すように、上述の回転体８２と、回転体８２に対して隙間をもって配された固定体８７と、回転体８２と固定体８７との隙間に配された粘性体８８とを具備している。一方向ダンパ８３は、当接部材８４に対する相対的な移動を生じるべく、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動において窓枠２に対して直動する回動アーム５１の窓枠２側の端部に伝達部材８６を介して当接するように、窓枠２に配設されている。   For example, as shown in FIGS. 11 to 14, the unidirectional damper 83 includes the above-described rotating body 82, a fixed body 87 disposed with a gap with respect to the rotating body 82, and a gap between the rotating body 82 and the fixed body 87. And a viscous body 88 disposed on the surface. The one-way damper 83 is a rotating arm that moves linearly with respect to the window frame 2 in the movement toward the opening closed position of the shoji 4 located in the vicinity of the opening closing position so as to cause a relative movement with respect to the contact member 84. 51 is arranged in the window frame 2 so as to abut on the end portion of the window frame 2 side through the transmission member 86.

回転体８２は、固定体８７に対する相対的な回転により粘性体８８を剪断するように固定体８７に隙間をもって配されている回転本体８９と、当接部材８４に対する移動により回転するように当該当接部材８４に当接する当接体９０と、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動において生じる回動アーム５１の窓枠２に対する直動に基づく当接部材８４に対する移動による当接体９０のＲ３方向の回転が回転本体８９に伝達される一方、当接体９０の逆回転としてのＲ４方向の回転が回転本体８９に伝達されないように、当接体９０と回転本体８９との間に介在されている一方向クラッチ９１とを具備している。当接体９０は、本例ではＲ３及びＲ４方向に回転自在な歯車９８からなる。歯車９８のＲ４方向の回転は、付勢部材８５の一方向ダンパ８３に対する付勢に基づく当該一方向ダンパ８３の当接部材８４に対する逆方向の移動によって生じる。   The rotating body 82 has a rotating body 89 disposed with a gap in the fixed body 87 so as to shear the viscous body 88 by relative rotation with respect to the fixed body 87, and the contact with the contact member 84 so as to rotate. A contact body 90 that contacts the contact member 84 and a contact member 84 that is based on the direct movement of the pivot arm 51 relative to the window frame 2 that occurs when the shoji 4 that is located near the opening closed position moves toward the opening closed position. The rotation in the R3 direction of the contact body 90 due to the movement is transmitted to the rotation main body 89, while the rotation in the R4 direction as the reverse rotation of the contact body 90 is not transmitted to the rotation main body 89. A one-way clutch 91 interposed between the main body 89 and the main body 89 is provided. The contact body 90 includes a gear 98 that is rotatable in the R3 and R4 directions in this example. The rotation of the gear 98 in the R4 direction is caused by the reverse movement of the unidirectional damper 83 with respect to the contact member 84 based on the urging of the urging member 85 with respect to the unidirectional damper 83.

固定体８７は、回転本体８９を覆うハウジングからなる。固定体８７は、回転本体８９の凹部９２に滑接して当該回転本体８９の揺動を防止する凸部９３を具備している。固定体８７は、縦枠１４の本体１７と板状体１８との間に鉛直方向Ｖに直動自在に配設されている。粘性体８８は、回転本体８９の固定体８７に対する相対的な回転に基づいて粘性抵抗力を生じるように、固定体８７と回転本体８９との隙間に収容されている。   The fixed body 87 is a housing that covers the rotating body 89. The fixed body 87 includes a convex portion 93 that slides into contact with the concave portion 92 of the rotary body 89 and prevents the rotary body 89 from swinging. The fixed body 87 is disposed between the main body 17 of the vertical frame 14 and the plate-like body 18 so as to be movable in the vertical direction V. The viscous body 88 is accommodated in the gap between the fixed body 87 and the rotary body 89 so as to generate a viscous resistance force based on the relative rotation of the rotary body 89 with respect to the fixed body 87.

円板状の回転本体８９は、例えば図１３に示すように、歯車９８が回転自在に装着されている軸部９４を具備している。軸部９４は、固定体８７から突出しており、固定体８７が配されている板状体１８の一方側から案内路７１を介して他方側まで伸びている。歯車９８は、板状体１８の他方側において軸部９４に回転自在に装着されている。   For example, as shown in FIG. 13, the disc-shaped rotating body 89 includes a shaft portion 94 on which a gear 98 is rotatably mounted. The shaft portion 94 protrudes from the fixed body 87 and extends from one side of the plate-like body 18 on which the fixed body 87 is disposed to the other side via the guide path 71. The gear 98 is rotatably mounted on the shaft portion 94 on the other side of the plate-like body 18.

一方向クラッチ９１は、例えば図１３示すように、本例では回転本体８９の軸部９４に巻き回されたコイルばね９５からなり、コイルばね９５の一端９６は歯車９８に固着されており、コイルばね９５の他端９７は自由端となっている。コイルばね９５は、歯車９８のＲ３方向の回転に基づいて縮径することで歯車９８を回転本体８９に対して連結し、これにより、歯車９８のＲ３方向の回転を回転本体８９に伝達するようになっている。また、コイルばね９５は、歯車９８のＲ４方向の回転に基づいて拡径することで歯車９８の回転本体８９に対する連結を解除し、これにより、歯車９８のＲ４方向の回転を回転本体８９に伝達しないようになっている。   For example, as shown in FIG. 13, the one-way clutch 91 includes a coil spring 95 wound around the shaft portion 94 of the rotary body 89, and one end 96 of the coil spring 95 is fixed to a gear 98. The other end 97 of the spring 95 is a free end. The coil spring 95 reduces the diameter based on the rotation of the gear 98 in the R3 direction, thereby connecting the gear 98 to the rotation main body 89, thereby transmitting the rotation of the gear 98 in the R3 direction to the rotation main body 89. It has become. Further, the coil spring 95 increases the diameter based on the rotation of the gear 98 in the R4 direction, thereby releasing the connection of the gear 98 to the rotating body 89, thereby transmitting the rotation of the gear 98 in the R4 direction to the rotating body 89. It is supposed not to.

当接部材８４は、本例では歯車９８に歯合したラック歯１０１を有していると共に、縦枠１４の板状体１８の他方側の部位に鉛直方向Ｖに伸びて固着されている歯竿部材１０２からなる。歯竿部材１０２に対する歯車９８の初期位置はラック歯１０１の上部に歯合する位置である。   In this example, the contact member 84 has a rack tooth 101 meshed with the gear 98 and is a tooth that extends in the vertical direction V and is fixed to the other side portion of the plate-like body 18 of the vertical frame 14. It consists of a gutter member 102. The initial position of the gear 98 with respect to the toothed member 102 is a position that meshes with the upper portion of the rack tooth 101.

付勢部材８５は、本例では、弾性により歯車９８を歯竿部材１０２に対する初期位置に復帰させるように一方向ダンパ８３を鉛直方向Ｖにおいて上方に向かって付勢する圧縮ばね１０３からなる。圧縮ばね１０３の一端１０４は固定体８７の下部に取り付けられており、圧縮ばね１０３の他端１０５は縦枠１４に支持されている。斯かる圧縮ばね１０３は、回動アーム５１の窓枠２に対する下方に向かう直動に基づく一方向ダンパ８３の下方に向かう直動により圧縮され、この圧縮により鉛直方向Ｖにおいて上方に向かう付勢力を一方向ダンパ８３に与えるようになっており、また、回動アーム５１の窓枠２に対する上方に向かう直動によって伝達部材８６が一方向ダンパ８３から離反した場合には、前記付勢力により一方向ダンパ８３を押圧して上方に向かって直動させて、初期位置に復帰させるようになっている。尚、圧縮ばね１０３の周囲には、当該圧縮ばね１０３の伸縮を案内する案内路を有した案内部材１０６が配設されていてもよい。   In this example, the urging member 85 includes a compression spring 103 that urges the unidirectional damper 83 upward in the vertical direction V so as to return the gear 98 to the initial position with respect to the toothed member 102 by elasticity. One end 104 of the compression spring 103 is attached to the lower part of the fixed body 87, and the other end 105 of the compression spring 103 is supported by the vertical frame 14. Such a compression spring 103 is compressed by a downward movement of the one-way damper 83 based on a downward movement of the rotating arm 51 relative to the window frame 2, and this compression generates an upward biasing force in the vertical direction V. When the transmission member 86 is separated from the one-way damper 83 due to the upward movement of the rotating arm 51 with respect to the window frame 2, the one-way damper 83 is applied to the one-way damper 83. The damper 83 is pressed and linearly moved upward to return to the initial position. A guide member 106 having a guide path for guiding expansion and contraction of the compression spring 103 may be disposed around the compression spring 103.

伝達部材８６は、回動アーム５１の窓枠２側の端部に装着されていると共に固定体８７の上面１０７に当接する当接面１０８を有したＬ字状の板状部材１０９からなる。板状部材１０９は、回動アーム５１の窓枠２側の端部の鉛直方向Ｖにおける直動によって直動される。板状部材１０９の当接面１０８は、障子４が開口閉鎖位置の近傍に位置した際に固定体８７の上面１０７に当接するように配されている。斯かる板状部材１０９は、障子４の開口閉鎖位置に向かう移動に基づく回動アーム５１の窓枠２に対する下方に向かう直動によって下方に向かって直動し、この直動により当接面１０８を上面１０７に当接させて当該直動を一方向ダンパ８３に伝達し、而して、回転体８２にＲ３方向の回転を生じさせるように一方向ダンパ８３を歯竿部材１０２に対して下方に向かって直動させるようになっており、また、回動アーム５１の窓枠２に対する上方に向かう直動によって上方に向かって直動し、この直動により当接面１０８を上面１０７から離反させるようになっている。尚、伝達部材８６及び一方向ダンパ８３には、当接面１０８が上面１０７に当接する際に互いに嵌合する一方、当接面１０８が上面１０７から離反する際に前記嵌合が解除される嵌合凸部１１０及び嵌合凹部１１１が形成されていてもよく、斯かる嵌合凸部１１０及び嵌合凹部１１１は、互いに嵌合することにより伝達部材８６及び一方向ダンパ８３の建物内外方向Ｘ及び横方向Ｙに関する相互の位置ずれを禁止するようになっていてもよい。   The transmission member 86 includes an L-shaped plate-like member 109 that is attached to the end of the rotating arm 51 on the window frame 2 side and has a contact surface 108 that contacts the upper surface 107 of the fixed body 87. The plate-like member 109 is linearly moved by the linear movement in the vertical direction V of the end of the rotating arm 51 on the window frame 2 side. The contact surface 108 of the plate-like member 109 is arranged so as to contact the upper surface 107 of the fixed body 87 when the shoji 4 is positioned in the vicinity of the opening closed position. The plate-like member 109 moves straight downward by the downward movement of the pivot arm 51 relative to the window frame 2 based on the movement of the shoji 4 toward the opening closed position, and the contact surface 108 is moved by this direct movement. Is brought into contact with the upper surface 107 to transmit the linear motion to the one-way damper 83, and thus the one-way damper 83 is moved downward with respect to the toothed member 102 so as to cause the rotating body 82 to rotate in the R3 direction. In addition, the rotary arm 51 is linearly moved upward by the linear movement of the rotating arm 51 with respect to the window frame 2, and the contact surface 108 is separated from the upper surface 107 by this linear movement. It is supposed to let you. The transmission member 86 and the one-way damper 83 are fitted to each other when the contact surface 108 is in contact with the upper surface 107, while the engagement is released when the contact surface 108 is separated from the upper surface 107. The fitting convex part 110 and the fitting concave part 111 may be formed, and the fitting convex part 110 and the fitting concave part 111 are fitted to each other so that the transmission member 86 and the one-way damper 83 are in the outside direction of the building. Mutual displacement between X and the lateral direction Y may be prohibited.

斯かる減衰機構８１は、障子４の開口閉鎖位置に向かう移動に基づく回動アーム５１の窓枠２に対する下方に向かう直動により伝達部材８６が下方に向かって直動し、この直動により当接面１０８が上面１０７に当接して一方向ダンパ８３に下方に向かう直動を伝達し、この伝達により一方向ダンパ８３を歯竿部材１０２に対して相対的に下方に向かって移動させ、この移動により歯車９８に生じるＲ４方向の回転を一方向クラッチ９１を介して回転本体８９に伝達し、この伝達により回転本体８９を固定体８７に対してＲ３方向に相対的に回転させて粘性体８８の粘性抵抗力を生じさせ、而して、障子４が開口閉鎖位置に到達する直前において回動アーム５１の窓枠２に対する下方に向かう直動を当該直動速度に依存した減衰力をもって減衰するようになっている。また、減衰機構８１は、歯車９８のＲ４方向の回転では回転本体８９の固定体８７に対する相対的な回転を生じさせないので、障子４の開口開放位置に向かう移動に伴って伝達部材８６が一方向ダンパ８３から離反されると、付勢部材８５により一方向ダンパ８３を初期位置に速やかに復帰させ得る。   In such a damping mechanism 81, the transmission member 86 moves linearly downward by the downward movement of the pivot arm 51 relative to the window frame 2 based on the movement of the shoji 4 toward the opening closed position. The contact surface 108 abuts on the upper surface 107 and transmits a downward linear motion to the one-way damper 83. By this transmission, the one-way damper 83 is moved downward relative to the toothed member 102. The rotation in the R4 direction generated in the gear 98 by the movement is transmitted to the rotating main body 89 via the one-way clutch 91, and the rotating main body 89 is rotated relative to the fixed body 87 in the R3 direction by this transmission, thereby causing the viscous body 88. Therefore, immediately before the shoji 4 reaches the opening closed position, the downward movement of the rotary arm 51 relative to the window frame 2 is reduced with a damping force depending on the linear movement speed. It has become way. Further, since the damping mechanism 81 does not cause relative rotation of the rotary body 89 with respect to the fixed body 87 when the gear 98 rotates in the R4 direction, the transmission member 86 moves in one direction along with the movement of the shoji 4 toward the opening opening position. When separated from the damper 83, the unidirectional damper 83 can be quickly returned to the initial position by the urging member 85.

障子４が図１０に示す開口閉鎖位置から図１５に示す開口閉鎖位置の近傍まで移動する場合においては、一方向ダンパ８３は、付勢部材８５に付勢されて、当接部材８４に対して鉛直方向Ｖにおいて上方に移動されるので、歯車９８はＲ４方向に回転されるが、斯かる回転は一方向クラッチ９１によって回転本体８９に伝達されないので回転本体８９の固定体８７に対する回転は生じず、而して、障子４の開口閉鎖位置から開口閉鎖位置の近傍までの移動は減衰されない。障子４が開口閉鎖位置の近傍から開口開放位置まで移動する場合においては、伝達部材８６が一方向ダンパ８３から離反するために回転体８２と固定体８７との相対的な回転は生じず、而して、斯かる移動は減衰されない。また、障子４が気流に基づいて開口閉鎖位置に向かって移動されて開口閉鎖位置の近傍に到達した場合においては、伝達部材８６が一方向ダンパ８３に当接し、この当接により回動アーム５１のＲ２方向の回動に基づく当該回動アーム５１の窓枠２の端部の下方に向かう直動が伝達部材８６を介して一方向ダンパ８３に伝達され、この伝達により一方向ダンパ８３は、付勢部材８５による付勢に抗して歯竿部材１０２に対して下方に向かって移動され、この移動により歯車９８がＲ３方向に回転され、この回転が一方向クラッチ９１を介して回転本体８９に伝達され、この伝達により回転本体８９は固定体８７に対して相対的に回転して粘性体８８の剪断による粘性抵抗力を生じ、而して、開口閉鎖位置の近傍に位置する障子４の開口閉鎖位置に向かう移動を当該移動速度に依存した減衰力をもって減衰する。また、減衰機構８１は、歯車９８のＲ４方向の回転では回転本体８９の固定体８７に対する相対的な回転を生じさせないので、回動アーム５１は窓枠２に対して上方に向かって速やかに直動され、而して、障子４を図１６に示す開口開放位置に向かって軽快に移動させ得る。   When the shoji 4 is moved from the opening closed position shown in FIG. 10 to the vicinity of the opening closing position shown in FIG. 15, the one-way damper 83 is urged by the urging member 85, Since it is moved upward in the vertical direction V, the gear 98 is rotated in the R4 direction, but such rotation is not transmitted to the rotating body 89 by the one-way clutch 91, so that rotation of the rotating body 89 relative to the fixed body 87 does not occur. Thus, the movement of the shoji 4 from the opening closed position to the vicinity of the opening closing position is not attenuated. When the shoji 4 moves from the vicinity of the opening closed position to the opening opening position, the transmission member 86 is separated from the one-way damper 83, so that the relative rotation between the rotating body 82 and the fixed body 87 does not occur. Thus, such movement is not attenuated. Further, when the shoji 4 is moved toward the opening closed position based on the air flow and reaches the vicinity of the opening closing position, the transmission member 86 comes into contact with the one-way damper 83, and the rotation arm 51 is brought into contact with this. The linear movement toward the lower side of the end of the window frame 2 of the rotating arm 51 based on the rotation in the R2 direction is transmitted to the one-way damper 83 through the transmission member 86, and the one-way damper 83 is transmitted by this transmission. The gear member 98 is moved downward relative to the toothed member 102 against the biasing force of the biasing member 85, and the gear 98 is rotated in the R3 direction by this movement, and this rotation is rotated through the one-way clutch 91. As a result of this transmission, the rotary body 89 rotates relative to the fixed body 87 to generate a viscous resistance force due to shearing of the viscous body 88, and thus the shoji 4 located near the opening closed position Open closed position Moving towards the decaying with a damping force that depends on the mobile speed. Further, since the damping mechanism 81 does not cause relative rotation of the rotating main body 89 with respect to the fixed body 87 when the gear 98 rotates in the R4 direction, the rotating arm 51 quickly and directly moves upward with respect to the window frame 2. Thus, the shoji 4 can be easily moved toward the opening opening position shown in FIG.

窓開閉装置８０は、減衰機構８１に代えて、例えば図１７から図１９に示すように、一方向ダンパ８３及び当接部材８４のうちの一方、本例では一方向ダンパ８３が、図１８に示すように開口閉鎖位置の近傍に位置する障子４の図１７に示す開口閉鎖位置に向かう移動において窓枠２に対して直動する回動アーム５１の部位、本例では回動アーム５１の窓枠２側の端部に装着されており、一方向ダンパ８３及び当接部材８４のうちの他方、本例では当接部材８４が窓枠２に固着されている減衰機構１１２を具備していてもよい。   For example, as shown in FIGS. 17 to 19, the window opening / closing device 80 is replaced with one of the one-way damper 83 and the abutting member 84, in this example, as shown in FIGS. 17 to 19. As shown in the figure, the part of the pivot arm 51 that moves linearly relative to the window frame 2 in the movement toward the opening closed position shown in FIG. 17 of the shoji 4 located in the vicinity of the opening closed position, in this example, the window of the pivot arm 51. It is attached to the end on the frame 2 side, and includes the other one of the one-way damper 83 and the abutting member 84, in this example, the attenuating mechanism 112 in which the abutting member 84 is fixed to the window frame 2. Also good.

開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動を減衰する減衰機構１１２は、減衰機構８１と同様に、回転体８２を有していると共に当該回転体８２の一方向としてのＲ３方向の回転に基づいて開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動において生じる回動アーム５１の窓枠２に対する直動を減衰するための抵抗力を生じる一方向ダンパ８３と、回転体８２に当接した状態における一方向ダンパ８３に対する相対的な移動により当該回転体８２を一方向に回転させる当接部材８４とを具備しており、一方向ダンパ８３及び当接部材８４のうちの一方としての一方向ダンパ８３は、回動アーム５１の前記直動に基づいて、一方向ダンパ８３及び当接部材８４の他方としての当接部材８４に対する前記相対的な移動を生じるようになっている。本例では、一方向ダンパ８３の固定体８７は、回動アーム５１の窓枠２側の端部に装着されており、当接部材８４は窓枠２に固着されており、当接体９０は歯車９８からなり、当接部材８４は歯竿部材１０２からなる。   The attenuation mechanism 112 for attenuating the movement of the shoji 4 located near the opening closed position toward the opening closed position has a rotating body 82 as well as the damping mechanism 81 and serves as one direction of the rotating body 82. One direction that generates a resistance force for attenuating the direct movement of the pivot arm 51 with respect to the window frame 2 caused by the movement of the shoji 4 located in the vicinity of the opening closing position toward the opening closing position based on the rotation in the R3 direction. A damper 83 and an abutting member 84 that rotates the rotating body 82 in one direction by relative movement with respect to the one-way damper 83 in a state of being in contact with the rotating body 82 are provided. The one-way damper 83 as one of the contact members 84 is opposed to the contact member 84 as the other of the one-way damper 83 and the contact member 84 based on the linear movement of the rotating arm 51. The adapted produce relative movement that. In this example, the fixed body 87 of the one-way damper 83 is attached to the end of the rotating arm 51 on the window frame 2 side, the contact member 84 is fixed to the window frame 2, and the contact body 90. Consists of a gear 98, and the contact member 84 consists of a toothed member 102.

斯かる減衰機構１１２は、障子４の開口閉鎖位置に向かう移動に基づく回動アーム５１の窓枠２に対する下方に向かう直動により一方向ダンパ８３が下方に向かって直動し、障子４が開口閉鎖位置の近傍に位置した際に歯車９８を歯竿部材１０２のラック歯１０１に歯合させ、一方向ダンパ８３の下方に向かう直動において歯車９８をラック歯１０１に対して相対的に移動させ、この移動によって生じる歯車９８のＲ３方向の回転を一方向クラッチ９１を介して回転本体８９に伝達し、この伝達により回転本体８９を固定体８７に対してＲ３方向に相対的に回転させて粘性体８８の粘性抵抗力を生じさせ、而して、障子４が開口閉鎖位置に到達する直前において回動アーム５１の窓枠２に対する下方に向かう直動を当該直動速度に依存した減衰力をもって減衰するようになっている。また、減衰機構１１２は、歯車９８のＲ４方向の回転では回転本体８９の固定体８７に対する相対的な回転を生じさせないので、回動アーム５１は窓枠２に対して上方に向かって速やかに直動され、而して、障子４を図１９に示す開口開放位置に向かって軽快に移動させ得る。   Such a damping mechanism 112 is configured such that the one-way damper 83 moves linearly downward by the linear movement of the rotating arm 51 downward relative to the window frame 2 based on the movement of the sliding paper 4 toward the opening closed position, and the sliding paper 4 opens. When positioned near the closed position, the gear 98 is engaged with the rack teeth 101 of the toothed member 102, and the gear 98 is moved relative to the rack teeth 101 in the linear motion downward of the one-way damper 83. The rotation in the R3 direction of the gear 98 caused by this movement is transmitted to the rotating main body 89 via the one-way clutch 91, and this transmission causes the rotating main body 89 to rotate relative to the fixed body 87 in the R3 direction. A viscous resistance force of the body 88 is generated, and thus the linear movement of the rotating arm 51 toward the window frame 2 immediately before the shoji 4 reaches the opening closed position is reduced depending on the linear movement speed. It is adapted to attenuate with the force. Further, since the damping mechanism 112 does not cause relative rotation of the rotating main body 89 with respect to the fixed body 87 by the rotation of the gear 98 in the R4 direction, the rotating arm 51 quickly and directly moves upward with respect to the window frame 2. Thus, the shoji 4 can be easily moved toward the opening opening position shown in FIG.

減衰機構１１２は、縦枠１４に支持されていると共に、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動において生じる回動アーム５１の窓枠２に対する直動において当該回動アーム５１の窓枠２側の端部に当接して当該端部に前記直動に抗する抗直動力を与える圧縮ばね１２１を更に具備していてもよい。   The damping mechanism 112 is supported by the vertical frame 14 and rotates in the linear movement of the rotary arm 51 with respect to the window frame 2 that occurs when the shoji 4 located near the opening closed position moves toward the opening closed position. The arm 51 may further include a compression spring 121 that abuts against an end portion of the arm 51 on the window frame 2 side and applies a resistance force to the end portion against the linear motion.

斯かる減衰機構８１及び１１２によれば、回転体８２を有していると共に当該回転体８２の一方向の回転に基づいて開口閉鎖位置の近傍に位置する障子４の当該開口開放位置に向かう移動において生じる回動アーム５１の窓枠２に対する直動を減衰するための抵抗力を生じる一方向ダンパ８３と、回転体８２に当接した状態における一方向ダンパ８３に対する相対的な移動により当該回転体８２を一方向に回転させる当接部材８４とを具備しており、一方向ダンパ８３及び当接部材８４のうちの一方は、回動アーム５１の前記直動に基づいて、一方向ダンパ８３及び当接部材８４の他方に対する前記相対的な移動を生じるようになっているために、障子４が開口閉鎖位置に到達する直前に当該障子４の開口閉鎖位置に向かう移動を減衰させることができ、而して、障子４の窓枠２に対する衝突を阻止し得る。一方向ダンパ８３は、回転体８２に対して隙間をもって配された固定体８７と、回転体８２と固定体８７との隙間に配された粘性体８８とを具備しており、回転体８２は、固定体８７に対する相対的な回転により粘性体８８を剪断するように固定体８７に隙間をもって配されている回転本体８９と、当接部材８４に対する移動により回転するように当該当接部材８４に当接する当接体９０と、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動において生じる回動アーム５１の窓枠２に対する直動に基づく当接部材８４に対する移動による当接体９０の回転が回転本体８９に伝達される一方、当接体９０の逆回転が回転本体８９に伝達されないように、当接体９０と回転本体８９との間に介在されている一方向クラッチ９１とを具備しているために、一方向クラッチ９１により当接体９０の逆回転が回転本体８９に伝達されないので、障子４が開口開放位置に向かって移動する際に一方向ダンパ８３及び当接部材８４の相対的な移動に基づく抵抗力を生じさせることなく、当該障子４の開口開放位置に向かう移動を軽快に行わせ得る。減衰機構８１においては、一方向ダンパ８３及び当接部材８４のうちの一方としての一方向ダンパ８３は、一方向ダンパ８３及び当接部材８４のうちの他方としての当接部材８４に対する相対的な移動を生じるべく、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動において障子４及び窓枠２のうちの一方に対して揺動する回動アーム５１の部位としての回動アーム５１の窓枠２側の端部に当接するように、窓枠２に配設されているために、回動アーム５１に一方向ダンパ８３又は当接部材８４を装着することがないので、障子４の開口開放位置に向かう移動及び開口閉鎖位置に向かう移動を軽快に行わせ得る。減衰機構８１は、一方向ダンパ８３及び当接部材８４のうちの一方としての一方向ダンパ８３を、一方向ダンパ８３及び当接部材８４のうちの他方としての当接部材８４に対する初期位置に復帰させるように付勢する付勢部材８５を更に具備しているために、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動に対する減衰を繰り返し行い得る。減衰機構１１２においては、一方向ダンパ８３及び当接部材８４のうちの一方としての一方向ダンパ８３は、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動において障子４及び窓枠２のうちの一方に対して揺動する回動アーム５１の部位として回動アーム５１の窓枠２側の端部に装着されており、一方向ダンパ８３及び当接部材８４のうちの他方としての当接部材８４は、窓枠２に固着されているために、減衰機構１１２が上述の付勢部材８５を具備していなくても、開口閉鎖位置の近傍に位置する障子４の当該開口閉鎖位置に向かう移動に対する減衰を繰り返し行い得る。窓開閉装置８０は、付製手段５並びに減衰機構８１又は１１２の双方を具備しているために上述の作用効果を好ましく奏し得るが、仮に付製手段５を具備していなくとも、減衰機構８１又は１１２による作用効果を奏し得る。   According to the damping mechanisms 81 and 112, the shoji 4 that has the rotating body 82 and is located in the vicinity of the opening closing position based on the rotation of the rotating body 82 in one direction moves toward the opening opening position. And a unidirectional damper 83 that generates a resistance force for attenuating the linear movement of the rotating arm 51 with respect to the window frame 2, and the rotator by relative movement with respect to the unidirectional damper 83 in contact with the rotator 82. An abutting member 84 that rotates 82 in one direction, and one of the one-way damper 83 and the abutting member 84 is based on the linear motion of the rotating arm 51 and the one-way damper 83 and Since the relative movement with respect to the other of the contact member 84 occurs, the movement of the shoji 4 toward the opening closed position is attenuated immediately before the shoji 4 reaches the opening closing position. Bets can be, and Thus, may prevent a collision against the window frame 2 of the sliding door 4. The one-way damper 83 includes a fixed body 87 disposed with a gap with respect to the rotating body 82, and a viscous body 88 disposed in the gap between the rotating body 82 and the fixed body 87. The rotating body 89 arranged with a gap in the fixed body 87 so as to shear the viscous body 88 by the relative rotation with respect to the fixed body 87, and the contact member 84 so as to rotate by the movement with respect to the contact member 84. Abutting due to movement of the abutting member 90 and the abutting member 84 based on the direct movement of the pivot arm 51 with respect to the window frame 2 that occurs in the movement of the shoji 4 located near the opening closing position toward the opening closing position. The one-way clutch interposed between the contact body 90 and the rotary body 89 so that the rotation of the body 90 is transmitted to the rotary body 89 while the reverse rotation of the contact body 90 is not transmitted to the rotary body 89. 9 Since the reverse rotation of the contact body 90 is not transmitted to the rotary body 89 by the one-way clutch 91, the one-way damper 83 and the contact are moved when the shoji 4 moves toward the opening opening position. The movement toward the opening opening position of the shoji 4 can be easily performed without generating a resistance force based on the relative movement of the member 84. In the damping mechanism 81, the one-way damper 83 as one of the one-way damper 83 and the contact member 84 is relative to the contact member 84 as the other of the one-way damper 83 and the contact member 84. Rotation as a part of the pivot arm 51 that swings with respect to one of the shoji 4 and the window frame 2 in the movement of the shoji 4 located in the vicinity of the opening closing position toward the opening closing position in order to cause the movement. Since the arm 51 is disposed on the window frame 2 so as to contact the end of the window frame 2 side, the one-way damper 83 or the contact member 84 is not attached to the rotating arm 51. The movement toward the opening opening position of the shoji 4 and the movement toward the opening closing position can be easily performed. The damping mechanism 81 returns the one-way damper 83 as one of the one-way damper 83 and the contact member 84 to the initial position with respect to the contact member 84 as the other of the one-way damper 83 and the contact member 84. Since the urging member 85 is further urged so as to urge the swaying member, it is possible to repeatedly attenuate the movement of the shoji 4 located near the opening closed position toward the opening closed position. In the damping mechanism 112, the one-way damper 83 as one of the one-way damper 83 and the abutting member 84 is configured so that the shoji 4 and the window are moved in the movement of the shoji 4 located near the opening closing position toward the opening closing position. The other end of the one-way damper 83 and the contact member 84 is attached to the end portion of the turning arm 51 on the side of the window frame 2 as a portion of the turning arm 51 that swings with respect to one of the frames 2. Since the abutting member 84 is fixed to the window frame 2, the opening of the shoji 4 located in the vicinity of the opening closing position even if the damping mechanism 112 does not include the above-described biasing member 85. Attenuation for movement toward the closed position can be repeated. Since the window opening / closing device 80 includes both the attachment means 5 and the attenuation mechanism 81 or 112, the above-described effects can be preferably achieved. However, even if the attachment means 5 is not provided, the attenuation mechanism 81 is provided. Or the effect by 112 can be show | played.
