Description

この発明は、たとえば高齢者用の福祉施設などの建築物に好適に適用可能な吊り戸のロック装置に関する。   The present invention relates to a lock device for a hanging door that can be suitably applied to a building such as a welfare facility for elderly people.

建築物の開口部に設置する吊り戸は、たとえばハンガレールを戸先側に低く傾斜させることにより、吊り戸の自重によって自動的に閉鎖させることができる。しかし、そのような吊り戸であっても、必要に応じて全開状態または中間の途中開度に保持するために、ストッパ装置を設けることが少なくない。   A suspension door installed at an opening of a building can be automatically closed by the weight of the suspension door, for example, by inclining a hanger rail toward the door tip side. However, even such a hanging door is often provided with a stopper device in order to maintain a fully open state or an intermediate halfway opening as required.

従来のストッパ装置は、たとえば吊り戸側と建物の壁面側との一方に板ばね製の弾性ストッパを設置し、ローラを介して弾性ストッパに係合するストッパ受けを他方に設置することにより、両者が係合する位置において吊り戸を制動して保持させることができる（特許文献１〜３）。ストッパ受けは、吊り戸の開方向、閉方向のいずれの側からでも弾性ストッパに係合させることができ、吊り戸の開閉ストローク内の任意の位置に吊り戸の保持位置を設定することができる。
特開２０００−１９２７０８号公報 特開２００３−３７２１号公報 特開２００３−２９３６４６号公報 For example, a conventional stopper device is configured such that an elastic stopper made of a leaf spring is installed on one of a suspension door side and a wall surface side of a building, and a stopper receiver that engages the elastic stopper via a roller is installed on the other side. The suspension door can be braked and held at the position where the two engage (Patent Documents 1 to 3). The stopper receiver can be engaged with the elastic stopper from either the opening direction or the closing direction of the suspension door, and the holding position of the suspension door can be set at any position within the opening / closing stroke of the suspension door. .
JP 2000-192708 A JP 2003-3721 A JP 2003-293646 A

かかる従来技術によるときは、ストッパ受けが弾性ストッパに係合することによる吊り戸の保持力は、保持中の吊り戸に大きな操作力を加えることにより両者の係合が解除され、吊り戸を開閉操作できる程度に設定する必要があるため、たとえば全開状態に保持されている吊り戸の把手に高齢者が不用意に体重をもたせかけると、吊り戸が移動し始めて思わぬ転倒事故が発生することがあるという問題があった。また、この問題を解決するために、たとえば周知のフランス落しや丸落しなどを使用するとすれば、床面に係合孔を設ける必要がある上、高齢者にとって必ずしも使い勝手がよくないという問題がある。   When such a conventional technique is used, the holding force of the suspension door due to the stopper receiver engaging with the elastic stopper is released by applying a large operating force to the suspension door being held, and the suspension door is opened and closed. For example, if an elderly person inadvertently puts a weight on the handle of a hanging door that is held in a fully open state, the hanging door will start to move and an unexpected fall accident may occur. There was a problem that there was. In order to solve this problem, for example, if a well-known French drop or a round drop is used, it is necessary to provide an engagement hole on the floor surface, and there is a problem that it is not always convenient for elderly people. .

そこで、この発明の目的は、かかる従来技術の問題に鑑み、吊り戸に搭載するデッドボルトと、長尺の係合部材とを組み合わせることによって、全開時、全閉時の吊り戸を確実に固定して高い安全性を実現することができる吊り戸のロック装置を提供することにある。   Therefore, in view of the problems of the prior art, the object of the present invention is to securely fix the hanging door when fully opened and fully closed by combining a dead bolt mounted on the hanging door and a long engagement member. It is another object of the present invention to provide a locking device for a hanging door that can realize high safety.

かかる目的を達成するためのこの発明の構成は、戸先側、戸尻側の吊車を介してハンガレールから前後に移動走行自在に吊下する吊り戸のロック装置であって、吊り戸の戸先側に上下動可能に搭載する上向きのデッドボルトと、デッドボルトに対応させてハンガレールと平行に設置する長尺の係合部材とを備えてなり、デッドボルトは、吊り戸を全閉位置にロックする吊り戸上の錠前用のサムターンを介して上下に駆動操作し、吊り戸の全開位置、全閉位置において、それぞれ係合部材の戸尻側、戸先側に係合することをその要旨とする。   The configuration of the present invention for achieving the above object is a locking device for a suspension door that is suspended from a hanger rail so as to be movable back and forth through a suspension vehicle on the door end side and the door bottom side. It is equipped with an upward dead bolt that can be moved up and down on the side, and a long engagement member that is installed in parallel with the hanger rail in correspondence with the dead bolt. The dead bolt locks the suspension door in the fully closed position. The gist is to drive up and down through a lock thumb turn on the hanging door and engage the door bottom side and the door end side of the engaging member at the fully open position and the fully closed position of the hanging door, respectively. .

なお、係合部材は、断面Ｚ形の板材としてハンガレールの下面にねじ止めすることができる。   The engaging member can be screwed to the lower surface of the hanger rail as a Z-shaped plate member.

また、係合部材は、ハンガレールの下方において、吊車に付設する外れ止めの下方に配置してもよく、外れ止めは、ハンガレールと係合部材との間に進入させてもよい。   In addition, the engaging member may be disposed below the hanger rail and below the detachment attached to the suspension wheel, and the detachable stopper may be inserted between the hanger rail and the engaging member.

かかる発明の構成によるときは、吊り戸の戸先側に搭載するデッドボルトは、吊り戸の全開位置において、係合部材の戸尻側に係合して吊り戸を閉鎖不能にロックすることができ、吊り戸の全閉位置において、係合部材の戸先側に係合して吊り戸を開放不能にロックすることができる。すなわち、全開位置、全閉位置の吊り戸は、たとえば高齢者が不用意に把手に体重をもたせかけたとしても、開閉方向に移動するおそれがなく、極めて安全である。なお、係合部材は、たとえば吊り戸の開閉ストローク相当の長さを有する長尺材であり、したがって、デッドボルトは、吊り戸の全開位置、全閉位置以外の中間位置において係合部材に係合することがなく、吊り戸が中間位置の途中開度に誤ってロックされてしまうこともない。   When the configuration of the present invention is adopted, the dead bolt mounted on the door end side of the suspension door may be engaged with the door butt side of the engagement member at the fully open position of the suspension door to lock the suspension door so that it cannot be closed. In the fully closed position of the suspension door, the suspension door can be locked so as not to be opened by engaging with the door end side of the engagement member. In other words, the hanging doors in the fully open position and the fully closed position are extremely safe because there is no risk of moving in the opening / closing direction even if the elderly person carelessly puts the weight on the handle. The engaging member is a long material having a length corresponding to, for example, the opening / closing stroke of the suspension door. Therefore, the dead bolt is engaged with the engagement member at an intermediate position other than the fully open position and the fully closed position of the suspension door. The suspension door is not accidentally locked to the middle opening of the intermediate position.

係合部材は、断面Ｚ形の板材としてハンガレールの下面にねじ止めすることにより、格別な取付用のスペースや部材を必要とすることがない。また、このような係合部材とハンガレールとの間の隙間に外れ止めを進入させれば、既存の外れ止め付きの吊車を備える吊り戸であっても、係合部材を簡単に組み合わせることができる。ただし、このときの係合部材、外れ止めは、ハンガレールの下方において、上から下にハンガレール、外れ止め、係合部材の順に配置されるものとする。   The engaging member is screwed to the lower surface of the hanger rail as a Z-shaped plate member, so that no special mounting space or member is required. In addition, if a stopper is inserted into the gap between the engaging member and the hanger rail, the engaging member can be easily combined even in a hanging door equipped with an existing suspension vehicle with a stopper. . However, at this time, the engaging member and the stopper are arranged in the order of the hanger rail, the stopper, and the engaging member from the top to the bottom below the hanger rail.

デッドボルトは、吊り戸に搭載する錠前用のサムターンを介して駆動操作することにより、吊り戸の全閉時に吊り戸をロックする錠前の一部として作動させることができる。   The dead bolt can be actuated as a part of the lock that locks the suspension door when the suspension door is fully closed by driving and operating through the thumb turn for the lock mounted on the suspension door.

以下、図面を以って発明の実施の形態を説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

吊り戸のロック装置は、吊り戸１０に搭載するデッドボルト１１と、吊り戸１０用のハンガレール２１に付設する長尺の係合部材２２とを備えてなる（図１、図２）。   The locking device for the suspension door includes a dead bolt 11 mounted on the suspension door 10 and a long engagement member 22 attached to the hanger rail 21 for the suspension door 10 (FIGS. 1 and 2).

吊り戸１０は、戸先側、戸尻側の吊車１２、１２を介してハンガレール２１から前後に移動走行自在に吊下されている。なお、図１、図２には、戸先側の吊車１２のみが図示されている。吊車１２は、吊り戸１０の上端面にねじ止めするブラケット１２ａに縦回転形のローラ１２ｂを組み付け、ローラ１２ｂをハンガレール２１に係合させている。   The suspension door 10 is suspended from the hanger rail 21 so as to be movable forward and backward through suspension wheels 12 and 12 on the door end side and the door bottom side. 1 and 2 show only the suspension vehicle 12 on the door end side. In the suspension vehicle 12, a vertically rotating roller 12 b is assembled to a bracket 12 a that is screwed to the upper end surface of the suspension door 10, and the roller 12 b is engaged with the hanger rail 21.

吊車１２のブラケット１２ａには、吊車１２の外れ止め１２ｃがねじ止めされている。外れ止め１２ｃは、ハンガレール２１の下面に対して僅かな隙間ｄ1 を介して保持されており、ローラ１２ｂがハンガレール２１から外れることを防止する。ハンガレール２１は、建物の駆体Ｗに対し、取付材２３を介して固定されている。   A suspension 12c of the suspension wheel 12 is screwed to the bracket 12a of the suspension vehicle 12. The stopper 12c is held with respect to the lower surface of the hanger rail 21 via a slight gap d1, and prevents the roller 12b from coming off the hanger rail 21. The hanger rail 21 is fixed to the building body W via a mounting member 23.

デッドボルト１１は、吊り戸１０の戸先側に上下動可能に上向きに搭載されている。デッドボルト１１の上端は、吊り戸１０の上端面のガイドプレート１１ａを下から上に貫通しており、下端は、連結ロッド１１ｂを介して吊り戸１０の錠前１３に連結されている。そこで、デッドボルト１１は、錠前１３用のサムターン１３ａを介して上下に駆動操作することができる。   The dead bolt 11 is mounted on the door end side of the suspension door 10 so as to be movable up and down. The upper end of the dead bolt 11 passes through the guide plate 11a on the upper end surface of the suspension door 10 from the bottom to the top, and the lower end is connected to the lock 13 of the suspension door 10 through the connection rod 11b. Therefore, the dead bolt 11 can be driven up and down via a thumb turn 13 a for the lock 13.

係合部材２２は、板材を断面Ｚ形に折曲げ加工して形成する長尺材であって、ハンガレール２１の下面にねじ止めされ、ハンガレール２１と平行に設置されている。係合部材２２の下側のフランジは、吊車１２に付設する外れ止め１２ｃの下にまで伸びており、したがって、外れ止め１２ｃは、ハンガレール２１と係合部材２２との間の隙間ｄ2 に進入している。なお、係合部材２２は、吊り戸１０の開閉ストローク相当の長さを有し、全長に亘って同一断面に形成されている。   The engagement member 22 is a long material formed by bending a plate material into a Z-shaped cross section. The engagement member 22 is screwed to the lower surface of the hanger rail 21 and installed in parallel with the hanger rail 21. The lower flange of the engaging member 22 extends under the locking stopper 12 c attached to the suspension wheel 12, and therefore the locking stopper 12 c enters the gap d 2 between the hanger rail 21 and the locking member 22. ing. The engaging member 22 has a length corresponding to the opening / closing stroke of the suspension door 10 and is formed in the same cross section over the entire length.

吊り戸１０は、吊車１２、１２を介し、全開位置、全閉位置に開閉することができる。したがって、吊り戸１０上のデッドボルト１１は、吊り戸１０の全開位置において、係合部材２２の戸尻側の先端に係合し（図１、図３）、吊り戸１０の全閉位置において、係合部材２２の戸先側の先端に係合する（図４）。すなわち、吊り戸１０の全開位置において、デッドボルト１１は、サムターン１３ａを介して上昇操作することにより（図３）、係合部材２２の戸尻側の先端に係合して吊り戸１０を閉鎖不能にロックすることができる。また、サムターン１３ａを介してデッドボルト１１を下降操作することにより、デッドボルト１１は、係合部材２２との係合が外れ（図１）、吊り戸１０を閉鎖方向に移動可能に解放する（同図の矢印方向）。ただし、吊り戸１０は、全開位置において、図示しない建物の開口部を全開に開放する。   The suspension door 10 can be opened and closed to the fully open position and the fully closed position via the suspension wheels 12 and 12. Accordingly, the dead bolt 11 on the suspension door 10 is engaged with the front end of the engagement member 22 at the fully open position of the suspension door 10 (FIGS. 1 and 3), and at the fully closed position of the suspension door 10. Then, it engages with the front end of the engagement member 22 (FIG. 4). That is, in the fully open position of the suspension door 10, the dead bolt 11 is lifted through the thumb turn 13a (FIG. 3) to engage the front end of the engagement member 22 and close the suspension door 10. Can be locked impossible. Further, by lowering the dead bolt 11 via the thumb turn 13a, the dead bolt 11 is disengaged from the engaging member 22 (FIG. 1), and the suspension door 10 is released so as to be movable in the closing direction ( Arrow direction in the figure). However, the suspension door 10 opens the opening of a building (not shown) to the fully open position at the fully open position.

吊り戸１０の全閉位置において、デッドボルト１１は、全開位置におけると全く同様にして、サムターン１３ａを介して上下に駆動操作可能である（図４）。すなわち、デッドボルト１１は、それを上昇させることにより（同図の実線）、係合部材２２の戸先側の先端に係合して吊り戸１０を開放不能にロックすることができる。また、デッドボルト１１を下降させると（同図の二点鎖線）、吊り戸１０は、開放方向に移動可能に解放される（同図の矢印方向）。ただし、吊り戸１０は、全閉位置において、図示しない建物の開口部を全閉に閉じ、吊り戸１０の戸先側は、図示しない戸枠の戸先側の竪枠に当接する。   In the fully closed position of the suspension door 10, the dead bolt 11 can be driven up and down via the thumb turn 13a in exactly the same manner as in the fully open position (FIG. 4). That is, the deadbolt 11 can be engaged with the front end of the engaging member 22 on the door end side to lock the suspension door 10 so that it cannot be opened by raising it (solid line in the figure). Further, when the dead bolt 11 is lowered (two-dot chain line in the figure), the suspension door 10 is released so as to be movable in the opening direction (arrow direction in the figure). However, in the fully closed position, the hanging door 10 closes the opening of a building (not shown) to be fully closed, and the door end side of the hanging door 10 abuts on a frame on the door tip side of the door frame (not shown).

吊り戸１０が全開位置、全閉位置の途中開度のときは（図５）、サムターン１３ａを回そうとしても、デッドボルト１１は、上端が係合部材２２と干渉するため上昇不能であり、吊り戸１０をロックすることがない。   When the suspension door 10 is in the fully open position and the halfway opening position of the fully closed position (FIG. 5), the dead bolt 11 cannot be raised because the upper end interferes with the engagement member 22 even if it tries to rotate the thumb turn 13a. The suspension door 10 is not locked.

以上の説明において、係合部材２２は、ハンガレール２１と別体とするに代えて、ハンガレール２１と一体に形成してもよい。ただし、このときの係合部材２２は、ハンガレール２１の全長と同長であるから、吊り戸１０の全開位置、全閉位置においてそれぞれデッドボルト１１が係合し得る係合孔または係合凹部などを戸尻側、戸先側に下向きに形成すればよい。   In the above description, the engaging member 22 may be formed integrally with the hanger rail 21 instead of being separated from the hanger rail 21. However, since the engagement member 22 at this time is the same length as the entire length of the hanger rail 21, an engagement hole or an engagement recess or the like in which the dead bolt 11 can be engaged in the fully open position and the fully closed position of the suspension door 10, respectively. May be formed downward on the door end side and the door tip side.
