Description
【０００１】[0001]
この考案は、引戸の開閉装置、更に詳しくは、引戸が閉鎖位置で開口部の気密 を保持すると共に、開放時には、引戸が上昇動し、円滑な移動操作が得られるよ うにした開閉装置に関する。 The present invention relates to an opening / closing device for a sliding door, and more particularly to an opening / closing device for keeping the airtightness of an opening at a closed position and for moving the sliding door upward when opening so that a smooth movement operation can be obtained.
【０００２】[0002]
従来の引戸、例えば吊戸は、開口部の上部に固定したレールに複数の戸車を移 動自在に設け、この戸車に戸部材を吊下げ状に取付け、レールの長手方向に沿っ て戸部材を開閉動させる構造になっており、戸部材が開閉動時に床面と接触しな いようにするため、戸部材は床面から浮かして取付けるのが一般的である。 In a conventional sliding door, for example, a hanging door, a plurality of door rollers are movably mounted on a rail fixed to the upper part of the opening, and a door member is attached to this door roller in a hanging manner, and the door members are attached along the longitudinal direction of the rail. It is structured to open and close, and in order to prevent the door member from coming into contact with the floor surface during opening and closing, it is common to mount the door member by floating it from the floor surface.
【０００３】[0003]
このため、従来の吊戸は、戸部材を閉鎖位置にしても、戸部材の下部と床面と の間に隙間が生じ、開口する出入口部分を気密状に閉鎖することができないと共 に、床面に戸部材の下部が当接する当りを設けて気密化を図ると、床面に突出部 分が生じ、歩行等に支障が生じるという問題がある。 Therefore, in the conventional hanging door, even when the door member is in the closed position, a gap is created between the lower portion of the door member and the floor surface, and the opening / closing port cannot be closed in an airtight manner. If a contact is made with the lower part of the door member on the floor surface to make it airtight, there is a problem that a protruding portion is generated on the floor surface, which causes troubles such as walking.
【０００４】 そこで、この考案の課題は、床面に突出部分を生じさせることなく、引戸によ って開口部分を気密状に閉鎖することができ、しかも引戸の開閉操作が円滑に行 える開閉装置を提供することにある。Therefore, an object of the present invention is to open and close an opening portion which can be closed in an airtight manner by a sliding door without causing a protruding portion on the floor surface, and which enables smooth opening and closing operations of the sliding door. To provide a device.
【０００５】[0005]
上記のような課題を解決するため、この考案は、レールに沿って移動自在とな る戸車に、ストッパーで制限された範囲を起伏動自在となる揺動アームを設け、 この揺動アームの先端に戸部材の取付部材を枢止し、前記戸車と、レールの該戸 車が閉鎖位置に停止する部分とに、戸車の閉鎖位置への進入を許容し、閉鎖位置 に停止する戸車の開方向への移動を阻止するストッパー機構を設け、このストッ パー機構の係止を揺動アームの起立によって解くようにした構成を採用したもの である。 In order to solve the above problems, the present invention provides a door roller movable along a rail with a swing arm capable of moving up and down within a range limited by a stopper, and a tip of the swing arm. The door member mounting member is pivotally attached to the door, and the door roller and the portion of the rail where the door roller stops in the closed position are allowed to enter the door closed position, and the door roller stops in the closed position. A stopper mechanism that prevents the movement of the stopper mechanism is provided, and the locking of this stopper mechanism is released by raising the swing arm.
【０００６】[0006]
戸部材が開位置にあるとき、揺動アームが起立して戸部材は上昇位置にあると 共に、戸部材を閉鎖方向に移動させると戸車も一体に移動し、戸部材が閉鎖位置 の直前に達して戸車が停止した状態で更に戸部材を閉鎖方向に押すと、揺動アー ムが伏倒位置に回動し、これによって戸部材は下降することにより戸当りに当接 し、開口部分を気密状に閉鎖する。 When the door member is in the open position, the swing arm stands up and the door member is in the raised position, and when the door member is moved in the closing direction, the door roller also moves integrally, and the door member is moved immediately before the door member is in the closed position. When the door pulley is reached and the door member is further pushed in the closing direction, the swing arm pivots to the lying position, which causes the door member to descend and abut against the door stop, opening the opening. Close in an airtight manner.
【０００７】 この状態で、ストッパー機構が係合し、開戸時に戸部材を開方向に押すと、ス トッパー機構によって戸車は停止したままであるので、揺動アームが起立方向に 回動し、戸部材は上昇しながら戸当りから離れ、揺動アームの起立と共にこの揺 動アームでストッパー機構の係止が解け、戸部材と共に戸車が開方向へ移動する ことになる。In this state, when the stopper mechanism is engaged and the door member is pushed in the opening direction when the door is opened, the swinger arm rotates in the upright direction because the door roller remains stopped by the stopper mechanism. The door member rises away from the door stop, and as the swing arm stands up, the swing arm disengages the stopper mechanism, and the door roller moves in the opening direction together with the door member.

Relationships are established. In addition, in the closed position, the lap portion of the door member 2 and the wall surface of the storage portion 3 overlap each other.
【００１９】 前記一方の戸車５の上部と、レール４内の上部で、戸部材２が閉鎖位置にある とき、戸当り２３に当接して停止する戸車５の直上位置とに、戸車５の閉鎖位置 への進入を許容し、閉鎖位置に停止する戸車５の開方向への移動を阻止するスト ッパー機構３１が設けられている。The door roller 5 is closed at the upper portion of the one door roller 5 and at a position directly above the door roller 5 which comes into contact with the door stop 23 and stops when the door member 2 is in the closed position in the upper portion of the rail 4. A stopper mechanism 31 is provided which allows the door 5 to enter the position and prevents the door roller 5 stopping at the closed position from moving in the opening direction.
【００２０】 このストッパー機構３１は、図３乃至図５の如く、車体１３の上壁１１に設け た長孔３２の部分に収まり、上下に揺動自在となるよう車体１３に取付けた係止 解除用アーム３３と、レール４の上壁内面に固定した取付杆３４と、この取付杆 ３４に一端を枢止したストッパー杆３５とからなる。As shown in FIGS. 3 to 5, the stopper mechanism 31 is housed in a long hole 32 provided in the upper wall 11 of the vehicle body 13 and is unlocked attached to the vehicle body 13 so as to be vertically swingable. The arm 33 includes a mounting rod 34 fixed to the inner surface of the upper wall of the rail 4, and a stopper rod 35 having one end pivotally fixed to the mounting rod 34.
【００２１】 上記係止解除アーム３３は、一方の端部を枢軸３６で車体１３に枢止し、この 枢軸３６を中心に上下に揺動可能となると共に、戸当り２３側に向く他方の端部 は、上壁１１の下面で長孔３２の端部に設けた支持段部３７の底面で支持され、 その上面が上壁１１の上面よりも下方に落ち込んだ姿勢に保持される。The unlocking arm 33 has one end pivotally fixed to the vehicle body 13 by a pivot 36, can swing up and down about the pivot 36, and has the other end facing the door stop 23 side. The portion is supported by the bottom surface of the support step portion 37 provided at the end of the elongated hole 32 on the lower surface of the upper wall 11, and the upper surface thereof is held in a posture in which it is lower than the upper surface of the upper wall 11.
【００２２】 この係止解除アーム３３は、車体１３内において、前記ストッパー１９、２０ 間の上部に位置し、かつ、起伏回動する揺動アーム１６の上端で取付部材１８の 枢止部が描く回動軌跡内に下面のカム縁３３ａが位置するよう配置され、揺動ア ーム１６が図３の如く、起立姿勢にあるときは、この揺動アーム１６の上端にお ける取付部材８の枢止部でカム面３３ａが押し上げられ、係止解除アーム３３は 上方に回動し、他方の端部が車体１３の上壁の上面よりも上方に位置する状態に なる。The unlocking arm 33 is located above the stoppers 19 and 20 in the vehicle body 13, and is drawn by the pivotal stop portion of the mounting member 18 at the upper end of the swinging arm 16 that rotates up and down. When the cam edge 33a on the lower surface is located in the turning locus and the swing arm 16 is in the upright posture as shown in FIG. 3, the mounting member 8 at the upper end of the swing arm 16 is placed. The cam surface 33a is pushed up by the pivotal stop, the unlocking arm 33 rotates upward, and the other end is positioned above the upper surface of the upper wall of the vehicle body 13.
【００２３】 又、揺動アーム１６が図４のように伏倒位置にあるときは、押し上げが解かれ るため、係止解除アーム３３は、他方端部が支持段部３７に載り、上壁１１の上 面よりも下方に落ち込んだ姿勢になる。Further, when the swing arm 16 is in the down position as shown in FIG. 4, the push-up is released, so that the other end of the lock release arm 33 rests on the support step 37 and the upper wall. The posture is lower than the upper surface of 11.
【００２４】 前記ストッパー杆３５は、その一端を取付杆３４に枢止する枢軸３８を中心に 上下に揺動自在となり、自重による下方への回動により、戸当り２３側に向く他 端側が係止解除アーム３３上に重なることになり、係止解除アーム３３が図４の ように、支持段部３７内に落ち込んだ姿勢のとき、このストッパー杆３５の他端 も支持段部３７内に落ち込み、この状態において、戸車５が開放方向に移動しよ うとした場合、支持段部３７の垂直面がストッパー杆３５の端部に当接して係合 し、戸車５の開放方向への移動が阻止されることになる。The stopper rod 35 is vertically swingable about a pivot 38 having one end pivotally fixed to the mounting rod 34, and is pivoted downward by its own weight so that the other end facing the door stop 23 side is engaged. As shown in FIG. 4, when the lock release arm 33 is in the posture in which it is dropped into the support step portion 37, the other end of the stopper rod 35 is also dropped into the support step portion 37. In this state, when the door roller 5 tries to move in the opening direction, the vertical surface of the support step portion 37 abuts and engages with the end portion of the stopper rod 35 to prevent the door roller 5 from moving in the opening direction. Will be done.
【００２５】 また、図３のように、揺動アーム１６の起立によって係止解除アーム３３が押 し上げられたとき、このアーム３３がストッパー杆３５を押し上げ、ストッパー 杆３５の他端を上壁１１の上面よりも上方に位置させることにより、支持段部３ ７とストッパー杆３５の係止を解き、戸車５の開放方向への移動を可能にする。Further, as shown in FIG. 3, when the unlocking arm 33 is pushed up by the standing of the swing arm 16, this arm 33 pushes up the stopper rod 35, and the other end of the stopper rod 35 is placed on the upper wall. By positioning it above the upper surface of 11, the support step portion 37 and the stopper rod 35 are unlocked and the door roller 5 can be moved in the opening direction.
【００２６】 なお、取付杆３４に対するストッパー杆３５の下降動を一定に制限するため、 ストッパー杆３５と取付杆３４の端部に一対の係止片３９、４０が設けてある。In order to limit the downward movement of the stopper rod 35 with respect to the attachment rod 34, a pair of locking pieces 39, 40 are provided at the ends of the stopper rod 35 and the attachment rod 34.
【００２７】 この考案の開閉装置の第１の例は上記のような構成であり、レール４内に設け た戸車５と６で戸部材２が吊下げ状に支持され、戸部材２を引手等を介して移動 させることにより、開口部１の開閉が行える。A first example of the opening / closing device of the present invention is configured as described above, and the door member 2 is supported in a hanging manner by door wheels 5 and 6 provided in the rail 4, and the door member 2 is pulled. The opening 1 can be opened and closed by moving the opening 1 through.
【００２８】 図１のように、戸部材２が開放位置にあるとき、戸車５及び６内の揺動アーム １６は起立姿勢にあり、戸部材２は床面２２から浮き上がっていると共に、スト ッパー機構３１における、係止解除アーム３３は揺動アーム１６で押し上げられ 、戸車５における上壁１１の上面に突出し、かつストッパー杆３５は下降位置に 保持されている。As shown in FIG. 1, when the door member 2 is in the open position, the swinging arms 16 in the door rollers 5 and 6 are in the upright posture, and the door member 2 is lifted from the floor surface 22 and is stopped by the stopper. The lock release arm 33 of the mechanism 31 is pushed up by the swing arm 16 to project onto the upper surface of the upper wall 11 of the door roller 5, and the stopper rod 35 is held in the lowered position.
【００２９】 上記戸部材２を閉鎖方向に移動させると、戸車５、６も一体に移動し、戸部材 ２が閉鎖位置の直前に達すると、図４のように、戸車５が戸当り２３に当接して 停止する。When the door member 2 is moved in the closing direction, the door wheels 5 and 6 move together, and when the door member 2 reaches just before the closed position, the door wheel 5 moves to the door stop 23 as shown in FIG. Abut and stop.
【００３０】 このとき、ストッパー機構３１におけるストッパー杆３５の直下を戸車５が進 入することになるが、このストッパー杆３５は戸車５の上面で押し上げられ、戸 車５の進入に支障を与えないと共に、戸車５が戸当り２３に当接して係止した時 点でストッパー杆３５は係止解除アーム３３上に載るとことになる。At this time, the door pulley 5 is pushed directly under the stopper rod 35 in the stopper mechanism 31, but the stopper rod 35 is pushed up by the upper surface of the door pulley 5 and does not hinder the entrance of the door pulley 5. At the same time, when the door roller 5 comes into contact with the door stop 23 and is locked, the stopper rod 35 is placed on the locking release arm 33.
【００３１】 この状態で戸部材２を更に閉鎖方向へ押圧すると、停止した戸車５、６に対し て、戸部材２と共にその取付部材１８、１８が戸当り２３側に移動しようとし、 この移動力により揺動アーム１６は、枢軸１５を支点に戸当り２３側へ向けて回 動し、戸部材２も枢軸１５を中心とする円弧運動を行うことにり、戸当り２３へ の接近と下方への移動により、図２と図４のように、戸部材２は戸当り２３に当 接した状態で下部が床面２２上に重なり、かつ突部９、９がパッキン１０、１０ 上に重なり、開口部１を気密上に閉鎖した状態となる。When the door member 2 is further pushed in the closing direction in this state, the mounting members 18, 18 together with the door member 2 try to move toward the door stop 23 side with respect to the stopped door pulleys 5, 6, and this moving force As a result, the swing arm 16 rotates about the pivot 15 toward the door stop 23 side, and the door member 2 also makes an arc motion centering on the pivot 15 to approach the door stop 23 and move downward. 2 and 4, the lower part of the door member 2 overlaps the floor surface 22 while the door member 2 is in contact with the door stop 23, and the projections 9 and 9 overlap the packings 10 and 10, respectively. The opening 1 is hermetically closed.
【００３２】 揺動アーム１６が下方に回動すると、押し上げの解かれた係止解除アーム３３ は下降して支持段部３７内に収まり、同時にストッパー杆１６も下降し、その他 方端部が支持段部３７内に落ち込む。When the swinging arm 16 rotates downward, the unlocking arm 33 that has been released from the pushing up moves down and fits in the support step portion 37, and at the same time, the stopper rod 16 also moves down and the other end portion is supported. It falls into the step 37.
【００３３】 次に、閉鎖位置の戸部材２を開放方向に引くと、同方向に取付部材１８、１８ も移動し、戸車５、６を開放方向に移動させようとするが、戸車５は、ストッパ ー杆３５と支持段部３７の係合により、開放方向の移動が阻止され、このため揺 動アーム１６が起立方向に回動し、戸部材２は戸当り２３から離反すると共に上 昇する。Next, when the door member 2 in the closed position is pulled in the opening direction, the mounting members 18, 18 also move in the same direction to move the door rollers 5, 6 in the opening direction. The engagement between the stopper rod 35 and the support step portion 37 prevents movement in the opening direction, so that the rocking arm 16 rotates in the upright direction, and the door member 2 moves away from the door stop 23 and rises. .
【００３４】 図３のように、揺動アーム１６が起立してストッパー２０に当接した状態で戸 部材２は床面から浮き上がると同時に、突部９、９がパッキン１０、１０から浮 き上がる。As shown in FIG. 3, with the swinging arm 16 standing upright and in contact with the stopper 20, the door member 2 is lifted from the floor surface, and at the same time, the protrusions 9 and 9 are lifted from the packings 10 and 10. .
【００３５】 揺動アーム１６が起立すると、その上端部で係止解除アーム３３を押し上げ、 図３の如く、このアーム３３でストッパー杆３５を戸車５の上面よりも上方に押 し上げる。When the swing arm 16 stands up, the lock release arm 33 is pushed up by the upper end portion thereof, and as shown in FIG. 3, the stopper rod 35 is pushed up above the upper surface of the door roller 5 by this arm 33.
