Description

本発明は、建築物内で出入り口として使用される開口部に設置される引き戸装置であって、引き戸装置の引き戸扉の吊り込みに関するものである。 The present invention relates to a sliding door device installed in an opening used as an entrance / exit in a building, and relates to hanging the sliding door of the sliding door device.

壁面などの開口部を開閉自在に閉塞する引き戸装置として、少なくとも固定部材であるレール取付材と、レール取付材に連結されるレール材と、レール材に吊りブラケットを介して吊り下げされる引き戸扉と、引き戸装置をメンテナンスするために開放可能なメンテナンスパネルからなる引き戸装置が提供されている。
そして、これらの引き戸装置の中には、レール材を引き戸扉の開放方向に向かって上昇するように傾斜させて固定し、傾斜させたレール材に沿って引き戸扉が摺動移動可能になるように施し、引き戸扉を手動で、レール材の傾斜の下方側から上方側に向かって開放移動させ、移動後に手を離すと、引き戸扉の自重によってレール材の傾斜の上方側から下方側に向かって自動に閉止移動させる半自動式のものがある。
このような引き戸装置のレール材に連結された吊りブラケットは、レール材に平行に連結されるため、吊りブラケットの引き戸扉を吊る位置は、引き戸扉の閉止側に対して、開放側がレールの傾斜角度分だけ上方の位置となっている。
そして、吊りブラケットの引き戸扉を吊る箇所は、メンテナンスパネルにて隠蔽されており、通常の引き戸装置の使用状態では、正面側から視認できないようになっている。
そのため、扉を吊り込むときは、メンテナンスパネルを一旦取り外し、吊りブラケットの引き戸扉を吊る箇所を露呈させて、引き戸扉を吊りブラケットに吊り込むようになっている。 As a sliding door device that opens and closes openings such as wall surfaces, at least a rail mounting material that is a fixing member, a rail material that is connected to the rail mounting material, and a sliding door that is suspended from the rail material via a hanging bracket. And, a sliding door device consisting of a maintenance panel that can be opened for maintaining the sliding door device is provided.
Then, in these sliding door devices, the rail material is tilted and fixed so as to rise toward the opening direction of the sliding door, and the sliding door can be slidably moved along the tilted rail material. The sliding door is manually opened and moved from the lower side to the upper side of the slope of the rail material, and when the hand is released after the movement, the weight of the sliding door moves from the upper side to the lower side of the slope of the rail material. There is a semi-automatic type that automatically closes and moves.
Since the hanging bracket connected to the rail material of such a sliding door device is connected in parallel with the rail material, the position where the sliding door of the hanging bracket is hung is tilted on the open side with respect to the closing side of the sliding door. It is positioned upward by the angle.
The part where the sliding door of the hanging bracket is hung is concealed by the maintenance panel so that it cannot be visually recognized from the front side in the normal use state of the sliding door device.
Therefore, when the door is hung, the maintenance panel is temporarily removed to expose the part where the sliding door of the hanging bracket is hung, and the sliding door is hung from the hanging bracket.

そして、メンテナンスパネルの重さや取りまわし、設置時の意匠性を考慮して、メンテナンスパネルの高さを抑えたメンテナンスパネルを備えた引き戸装置が本願出願人によって提供されている（特許文献１）。
しかしながら、メンテナンスパネルの高さを抑えた場合、引き戸装置の吊りブラケットの引き戸扉を吊る位置は、引き戸扉の閉止側に対して、開放側がレールの傾斜角度分だけ上方の位置となっているから、上方の位置側となっている前記吊る位置は、メンテナンスパネルを外して露呈している箇所の上端部に近接することや、該上端部より上方に位置することがあり、引き戸扉を吊り込んだ後の引き戸扉の高さ調整や、吊り込んだ引き戸扉の脱落防止部材を取り付けることがやり難い問題があった。
また、メンテナンスパネルの高さをさらに抑えたくても、上方の位置側となっている前記吊る位置がメンテナンスパネル外した後に露呈する必要があるため、容易には出来なかった。 Then, the applicant of the present application provides a sliding door device provided with a maintenance panel in which the height of the maintenance panel is suppressed in consideration of the weight and handling of the maintenance panel and the design at the time of installation (Patent Document 1).
However, when the height of the maintenance panel is suppressed, the position where the sliding door of the hanging bracket of the sliding door device is hung is higher than the closing side of the sliding door by the inclination angle of the rail on the open side. The hanging position, which is on the upper position side, may be close to the upper end of the exposed portion by removing the maintenance panel, or may be located above the upper end, and the sliding door may be suspended. After that, there was a problem that it was difficult to adjust the height of the sliding door and attach a fall-prevention member for the suspended sliding door.
Further, even if it is desired to further reduce the height of the maintenance panel, it cannot be easily done because the hanging position on the upper position side needs to be exposed after the maintenance panel is removed.

本発明は、従来の問題点に鑑みて、レール材が傾斜設置されていても引き戸扉の吊り込み作業が容易となる傾斜レール式引き戸装置の吊りブラケットの提供することを課題とする。 In view of the conventional problems, it is an object of the present invention to provide a hanging bracket for an inclined rail type sliding door device that facilitates the hanging work of the sliding door even if the rail material is inclined.

そこで、上記課題を解決する為、本発明が第１の手段として構成したところは、壁面などの開口部を開閉自在に閉塞する引き戸装置であって、引き戸装置は、少なくともレール取付材と、レール取付材に連結されるスライドレールと、スライドレールに、吊りブラケットと高さ調整自在な吊り下げ具を介して吊り下げされる引き戸扉と、引き戸装置の調整などを行うメンテナンス開口部と、該メンテナンス開口部を閉塞するメンテナンスパネルからなり、スライドレールを引き戸扉の開放方向側に向かって上方に傾斜するように設置し、スライドレールに引き戸扉を吊りブラケットを介してスライドレールに対して摺動自在に吊り下げ、スライドレールの傾斜に合わせて、引き戸扉を上方に向かって摺動移動させると、該摺動位置から、引き戸扉が引き戸扉の自重によって、スライドレールの傾斜の下方側に摺動移動する傾斜レール式引き戸装置において、スライドレールは、少なくともアウターメンバーと、アウターメンバーに対して複数のボールによって摺動自在に保持されるインナーメンバーと、複数のボールを保持するボールリテーナよりなるボールベアリング式であって、吊りブラケットは、インナーメンバーと連結され、インナーメンバーの摺動移動に合わせて摺動移動するものであって、吊りブラケットは、インナーメンバーの下方で引き戸扉を吊り下げる吊り下げ部を少なくとも戸先側と戸尻側のそれぞれに有したものであって、スライドレールを、メンテナンス開口部の正面視において、スライドレールの大部分が露呈しないようにメンテナンス開口部の上端より上方の位置に設置し、戸先側の吊り下げ部と、戸尻側の吊り下げ部のそれぞれの吊り下げ部と、該吊り下げ部の上方のスライドレールの下端との高さ方向の距離を、戸先側の吊り下げ部より戸尻側の吊り下げ部を高く設定する構成とした。 Therefore, in order to solve the above problems, what the present invention has configured as the first means is a sliding door device that movably closes an opening such as a wall surface, and the sliding door device is at least a rail mounting material and a rail. A slide rail connected to a mounting material, a sliding door that is hung from the slide rail via a hanging bracket and a height-adjustable hanging tool, a maintenance opening for adjusting the sliding door device, and the maintenance. It consists of a maintenance panel that closes the opening, and the slide rail is installed so as to incline upward toward the opening direction side of the sliding door, and the sliding door is slidable to the slide rail via the hanging bracket. When the sliding door is slid upward according to the inclination of the slide rail, the sliding door slides downward from the sliding position due to the weight of the sliding door. In a moving inclined rail type sliding door device, the slide rail is a ball bearing consisting of at least an outer member, an inner member slidably held by a plurality of balls with respect to the outer member, and a ball retainer holding a plurality of balls. In the formula, the hanging bracket is connected to the inner member and slides and moves according to the sliding movement of the inner member. The hanging bracket is a hanging portion that suspends the sliding door below the inner member. The slide rail is located above the upper end of the maintenance opening so that most of the slide rail is not exposed in the front view of the maintenance opening. The distance in the height direction between the hanging part on the door end side, the hanging part on the door end side, and the lower end of the slide rail above the hanging part is set in the door. The hanging part on the door end side is set higher than the hanging part on the side.

次に、上記課題を解決する為、本発明が第２の手段として構成したところは、第１の手段として構成したところに加え、戸先側の吊り下げ部と戸尻側の吊り下げ部は、出入り口開口部の床面から略同じ高さ位置になるように構成した。 Next, in order to solve the above problems, the place where the present invention is configured as the second means is that the hanging part on the door end side and the hanging part on the door tail side are in addition to the place configured as the first means. , It was configured to be at approximately the same height as the floor surface of the doorway opening.

請求項１に記載の発明によると、通常、引き戸扉の下面は、床面と平行となるように設置されるが、スライドレールが規定の角度に傾斜設置された状態で、吊り下げ部の上方の傾斜されたスライドレールの下端に対して、戸尻側の吊り下げ部を、戸先側の吊り下げ部より高い距離に設定されているから、スライドレールの傾斜に合わせて戸尻側の吊り下げ部の位置が、戸先側の吊り下げ部の位置より高くなることを抑えられ、戸先側の吊り下げ部の位置と略同じ高さになるので、戸尻側の吊り下げ部付近が、メンテナンス開口部より上方に隠れることを防止でき、引き戸扉を吊り金具に吊り下げた後の引き戸扉の高さ調整や、引き戸扉が吊り金具から脱落することを防止する部材の設置などが容易に行うことが可能である。 According to the invention of claim 1, the lower surface of the sliding door is normally installed so as to be parallel to the floor surface, but above the hanging portion with the slide rail tilted at a predetermined angle. Since the hanging part on the door tail side is set at a higher distance than the hanging part on the door end side with respect to the lower end of the inclined slide rail, the hanging part on the door tail side is hung according to the inclination of the slide rail. The position of the hanging part can be prevented from becoming higher than the position of the hanging part on the door end side, and the height is almost the same as the position of the hanging part on the door end side. , Maintenance It is possible to prevent hiding above the opening, and it is easy to adjust the height of the sliding door after hanging the sliding door on the hanging bracket, and to install a member to prevent the sliding door from falling off from the hanging bracket. It is possible to do it.

請求項２に記載の発明によると、上記効果に加え、床面と略平行となるように吊りブラケットの引き戸扉の吊り下げ部が構成されているから、吊り下げ具の上方への突出高さを、戸先側と戸尻側で略同じ高さに設定するだけでいいので、引き戸扉の吊りブラケットへの吊り込み作業が容易になる。
また、スライドレールが戸尻側に向かって上昇するように傾斜しているのにも係らず、戸尻側の吊り下げ部が戸先側の吊り下げ部と同様にメンテナンス開口部から露呈するから、メンテナンス開放部の高さ寸法を小さくしたとしても、容易に引き戸扉を吊り込むことが可能である。
さらに、メンテナンスパネルの高さを、出入り口の出入り方向のメンテナンス側と対向する側の室外側化粧突部（上枠）の高さと同じ高さに合わせることが可能となり、引き戸装置が設置され壁面が仕上げられた状態での引き戸枠の露呈している意匠が室内側と室外側で略同じ見栄えとなる。
そのため、意匠上の理由で目立たない室内側に設置されるメンテナンスパネルを室外側に設置することが可能となり、メンテナンスパネルを室外側に設置すると、室内の使用状況に係らず、メンテナンス作業が可能となる。 According to the second aspect of the present invention, in addition to the above effects, the hanging portion of the sliding door of the hanging bracket is configured so as to be substantially parallel to the floor surface, so that the hanging height of the hanging tool is projected upward. Since it is only necessary to set the door tip side and the door tail side to substantially the same height, the work of hanging the sliding door door to the hanging bracket becomes easy.
Also, even though the slide rail is tilted so as to rise toward the door tail side, the hanging part on the door tail side is exposed from the maintenance opening like the hanging part on the door end side. Even if the height dimension of the maintenance opening is reduced, the sliding door can be easily hung.
Furthermore, the height of the maintenance panel can be adjusted to the same height as the height of the outdoor decorative protrusion (upper frame) on the side facing the maintenance side in the entrance / exit direction, and a sliding door device is installed to make the wall surface. The exposed design of the sliding door frame in the finished state looks almost the same on the indoor side and the outdoor side.
Therefore, it is possible to install the maintenance panel installed on the indoor side, which is inconspicuous for design reasons, on the outdoor side, and if the maintenance panel is installed on the outdoor side, maintenance work can be performed regardless of the indoor usage situation. Become.

より具体的には、メンテナンスパネル７３が取り外された状態のメンテナンス開放部８より、戸先側と戸尻側の揺れ止め部材２４５、２４５の上端を最も低い位置まで下げた状態で、引き戸扉６の吊り下げボルト６１、６１の螺軸部６２、６２を、吊り下げボルト挿通孔５５６、５５６に挿入して、ボルト頭部６３を吊り下げ用支持面５５２に載置させ、必要に応じて頭部６３、６３をスパナで回動して引き戸扉６を所定の高さに位置させる。
通常、引き戸扉６の下面は、床面と平行となるように設置されるが、レールベース材２（レール材５）の規定の角度に傾斜設置された状態で床面と略平行となるように吊りブラケット５５が構成されているから、吊り下げボルト６１、６１の上方への突出高さは戸先側と戸尻側で略同じ高さに設定するだけでいいので、引き戸扉６の吊り込み作業は容易である。 More specifically, the sliding door 6 is in a state where the upper ends of the anti-sway members 245 and 245 on the door end side and the door tail side are lowered to the lowest position from the maintenance opening portion 8 in the state where the maintenance panel 73 is removed. The screw shaft portions 62, 62 of the hanging bolts 61, 61 are inserted into the hanging bolt insertion holes 556, 556, and the bolt head 63 is placed on the hanging support surface 552, and the head is placed if necessary. The portions 63 and 63 are rotated by a spanner to position the sliding door 6 at a predetermined height.
Normally, the lower surface of the sliding door 6 is installed so as to be parallel to the floor surface, but the lower surface of the sliding door 6 is installed so as to be substantially parallel to the floor surface in a state where the rail base material 2 (rail material 5) is installed at an inclined angle. Since the hanging bracket 55 is configured on the door, the hanging heights of the hanging bolts 61 and 61 need only be set to substantially the same height on the door tip side and the door tail side, so that the sliding door 6 is suspended. The crowding work is easy.

次に、ボルト頭部６３を回動させて戸当たり部材６００と戸先側縦枠１４の閉鎖用凹部１４８との当り具合などを調整した後、ボルト保持体６５、６５が、メンテナンス開放部８から臨む垂下面５５３（螺孔５５７）にネジにて連結されて、レール材５に吊りブラケット５５を介して吊り下げられる。
この状態で、回動防止片６５２、６５２がボルト頭部６３の戸先側と戸尻側に位置するので、吊下げボルト６１が不用意に回動することがなく、引き戸扉６は確実に所定の高さに維持されるとともに、ボルト保持体６５の移動防止片６５３が、吊り下げボルト６１のボルト頭部６３の室内側に位置するので、吊り下げボルト６１が吊り下げボルト挿通孔５５６から脱落するのを防止することができる。
このようにメンテナンス開放部８を正面視した状態で、戸先側吊り下げ部５５ａ、戸尻側吊り下げ部５５ｂの垂下面５５３（螺孔５５７）が露呈しているので、ボルト頭部６３の回転させることに加え、ボルト保持体６５の取り付けも容易に行える。 Next, the bolt head 63 is rotated to adjust the contact condition between the door stop member 600 and the closing recess 148 of the door end side vertical frame 14, and then the bolt holders 65 and 65 are subjected to the maintenance opening portion 8. It is connected to the hanging lower surface 553 (screw hole 557) facing from the rail material 5 with a screw, and is suspended from the rail material 5 via the suspension bracket 55.
In this state, since the rotation prevention pieces 652 and 652 are located on the door tip side and the door tail side of the bolt head 63, the hanging bolt 61 does not rotate carelessly, and the sliding door 6 is surely Since the movement prevention piece 653 of the bolt holder 65 is located on the indoor side of the bolt head 63 of the hanging bolt 61 while being maintained at a predetermined height, the hanging bolt 61 is inserted from the hanging bolt insertion hole 556. It can be prevented from falling off.
In this way, when the maintenance opening portion 8 is viewed from the front, the hanging surface 553 (screw hole 557) of the door end side hanging portion 55a and the door tail side hanging portion 55b is exposed, so that the bolt head 63 is exposed. In addition to rotating, the bolt holder 65 can be easily attached.

次に、揺れ止め部材２４５、２４５を、固定ネジを緩めて上昇させ、横振れ規制部材２４の室内側突片を上方の凹溝で抱え込むように位置させ、固定ネジを締めて所定高さに固定する。
さらに、引き戸扉６を吊り下げた状態で、引き戸扉６の開閉速度を確認し、必要に応じてレールベース材２の傾斜角度を調節し、引き戸扉６の開閉速度を設定する。
その他、全開ストッパー、ブレーキ装置、フリーストッパー装置等のオプション部材がメンテナンス開放部８から取り付けられる。 Next, the anti-sway members 245 and 245 are lifted by loosening the fixing screws, positioned so as to hold the indoor side protrusions of the lateral vibration regulating member 24 in the upper concave groove, and tighten the fixing screws to a predetermined height. Fix it.
Further, with the sliding door 6 suspended, the opening / closing speed of the sliding door 6 is confirmed, the inclination angle of the rail base material 2 is adjusted as necessary, and the opening / closing speed of the sliding door 6 is set.
In addition, optional members such as a fully open stopper, a brake device, and a free stopper device are attached from the maintenance opening portion 8.

メンテナンスパネル７３は、図３に示すように、室内側の上方から基板側下突片７２１の先端部分に載置され、室内側化粧ボード１００に張られたクロス１０３の下縁を隠蔽する載置用突片７３１と、出入口上部の室内側を閉塞するＬ字形の室内側閉塞部７３２より構成され、室内側閉塞部７３２で、戸先側縦枠１４と室内側中枠３の上端部出入口側内面に取り付けられた室内側ランマ下地パネル７のコ字状に形成された突部連結座７０、７０の下面側に化粧ネジ７００、７００にて連結する。 As shown in FIG. 3, the maintenance panel 73 is placed on the tip portion of the substrate-side lower projecting piece 721 from above the indoor side, and is placed so as to hide the lower edge of the cloth 103 stretched on the indoor-side decorative board 100. It is composed of a projecting piece 731 and an L-shaped indoor side closing portion 732 that closes the indoor side of the upper part of the doorway. It is connected to the lower surface side of the protrusion connecting seats 70 and 70 formed in a U shape of the indoor side rammer base panel 7 attached to the inner surface with decorative screws 700 and 700.

前述のとおり、室内側ランマ下地パネル７が、レール取付材１５の室内側垂下突片１５２から垂れ下がるように設置されているから、レール材５は、メンテナンス開放部８を正面視した状態でその大部分が露呈しないようになっている。
したがって、メンテナンス開放部８の高さ方向を低く抑えることができるため、メンテナンスパネル７３の高さ方向をメンテナンス開放部８の高さ寸法に合わせて小さくでき、メンテナンスパネル７３の重量を軽減でき、メンテナンス作業時のメンテナンスパネル７３の着脱などの取り回しが容易となる。 As described above, since the indoor side rammer base panel 7 is installed so as to hang down from the indoor side hanging projection piece 152 of the rail mounting material 15, the rail material 5 has a large size when the maintenance opening portion 8 is viewed from the front. The part is not exposed.
Therefore, since the height direction of the maintenance opening portion 8 can be suppressed low, the height direction of the maintenance panel 73 can be reduced according to the height dimension of the maintenance opening portion 8, the weight of the maintenance panel 73 can be reduced, and maintenance can be performed. The maintenance panel 73 can be easily attached and detached during work.

さらに、本実施例では、吊り下げボルト挿通孔５５６、５５６を含む吊り下げ支持面５５２が、レールベース材２（レール材５）の規定の角度に傾斜設置された状態で、図２で示す、ａ、ａ寸法のように床面と略平行となるように吊りブラケット５５が構成されているから、メンテナンス開放部８の高さ寸法をさらに小さくしたとしても引き戸扉６を吊り下げボルト挿通孔５５６、５５６に吊り込むことが可能である。
具体的には、図８に示すように、メンテナンスパネル７３の高さを、室外側ランマ下地パネル１９の室外側化粧突部１９３の高さに合わせることが可能となり、引き戸装置が設置され壁面が仕上げられた状態での引き戸枠１の露呈している意匠が室内側と室外側で略同じ見栄えとなる。
そのため、通常意匠上の理由で目立たない室内側に設置されるメンテナンスパネルを室外側に設置することが可能となる。
メンテナンスパネルを室外側に設置すると、室内の使用状況に係らず、メンテナンス作業が可能となる。
また、レールベース材２（レール材５）の傾斜に合わせて、戸尻側の吊り下げボルト挿通孔５５６の位置が、戸先側の吊り下げボルト挿通孔５５６より高くなることがないので、戸尻側のボルト挿通孔５５６や垂下面５５３の螺孔５５７が、室内側ランマ下地パネル７の基板側下突片７２１の下部に隠れることを防止できるため、吊り下げボルト６１の突出量の設定や、ボルト頭部６３の回転作業、ボルト保持体６５の固定も容易である。 Further, in this embodiment, the suspension support surface 552 including the suspension bolt insertion holes 556 and 556 is shown in FIG. 2 in a state where the suspension support surface 552 is inclined and installed at a specified angle of the rail base material 2 (rail material 5). Since the suspension bracket 55 is configured so as to be substantially parallel to the floor surface as in the dimensions a and a, the sliding door 6 can be suspended and the bolt insertion hole 556 even if the height dimension of the maintenance opening portion 8 is further reduced. It can be hung at 556.
Specifically, as shown in FIG. 8, the height of the maintenance panel 73 can be adjusted to the height of the outdoor decorative protrusion 193 of the outdoor rammer base panel 19, and a sliding door device is installed to cover the wall surface. The exposed design of the sliding door frame 1 in the finished state has substantially the same appearance on the indoor side and the outdoor side.
Therefore, it is possible to install the maintenance panel on the indoor side, which is usually inconspicuous for design reasons, on the outdoor side.
If the maintenance panel is installed outside the room, maintenance work can be performed regardless of the usage conditions inside the room.
Further, since the position of the hanging bolt insertion hole 556 on the door tail side does not become higher than the hanging bolt insertion hole 556 on the door end side according to the inclination of the rail base material 2 (rail material 5), the door Since it is possible to prevent the bolt insertion hole 556 on the tail side and the screw hole 557 on the hanging lower surface 555 from being hidden under the lower projecting piece 721 on the board side of the indoor rammer base panel 7, the amount of protrusion of the hanging bolt 61 can be set. It is easy to rotate the bolt head 63 and fix the bolt holder 65.

メンテナンスパネル７３は、最終仕上げが施された（レールベース材２、引き戸扉６等がとりつけられた）後、メンテナンスパネル７３の載置用突片７３１を基板側下突片７２１に外側上方から載置し、突部連結座７０、７０に室内側閉塞部７３２が下面からネジ止め連結されて出入口の上部に設けられる。
そして、戸先側縦枠１４の室内側ボード閉塞突部１４６と、室外側ボード閉塞突部１４７と、室内側中枠突部３２と室外側中枠突部３０２と、メンテナンスパネル７３と室外側化粧突部１９３が化粧ボード１００より外側に突出してあらわれることとなる。 After the maintenance panel 73 is finally finished (rail base material 2, sliding door 6, etc. are attached), the mounting protrusion 731 of the maintenance panel 73 is mounted on the lower protrusion 721 on the substrate side from the outside upper side. The indoor side closing portion 732 is screwed and connected from the lower surface to the protrusion connecting seats 70 and 70 to be provided at the upper part of the doorway.
Then, the indoor side board closing protrusion 146, the outdoor side board closing protrusion 147, the indoor side middle frame protrusion 32, the outdoor middle frame protrusion 302, the maintenance panel 73, and the outdoor side of the door end side vertical frame 14 The decorative protrusion 193 will appear protruding outward from the decorative board 100.
