Description

本発明は、上吊引戸に関するもので、より詳しくは上吊引戸における障子下部側のガイド機構の改良に関する。 The present invention relates to an upper suspension door, and more particularly to an improvement of a guide mechanism on a lower side of a shoji in the upper suspension door.

引戸の一形態として、上枠のレールに障子を吊下げて障子の開閉を行う上吊引戸があり、例えば建物の出入口に設置される自動ドアは、一般に上吊引戸の形態をとっている。自動ドアの障子は、上部に設けた戸車を上枠のレールに引っ掛けて吊下げられ、上枠に内蔵したリニアモータ等の駆動機構の働きによって左右に移動するようになっており、障子の下部には振れ止めを下方に突出して設けてあり、この振れ止めを下枠に設けた凹溝状のレール内に挿入し、障子の下部側をガイドしている（例えば、特許文献１参照。）。 As one form of the sliding door, there is an upper hanging door that opens and closes the shoji by hanging the shoji on the rail of the upper frame. For example, an automatic door installed at a doorway of a building generally takes the form of an upper hanging door. The sliding door of the automatic door is hung by hanging the top wheel on the rail of the upper frame, and it moves to the left and right by the action of a drive mechanism such as a linear motor built in the upper frame. In this case, a steady rest is provided so as to protrude downward, and this steady rest is inserted into a groove-shaped rail provided in the lower frame to guide the lower side of the shoji (see, for example, Patent Document 1). .

上記した従来の自動ドアでは、下枠のレールが凹溝状に床面から凹んで形成されているため、ハイヒールを履いた女性が自動ドアを通過する際、ヒールの先が下枠のレールに嵌まり込み、転倒したりヒールが破損したりすることがあった。また、レール内にゴミが溜まりやすく、掃除も容易に行えない。そこで本出願人は、下枠のレールを凹溝状ではなく凸状のレールにした上吊引戸を開発し、特許出願している（特願２００３−３００７８６号）。
特開２００２−７０３９９号公報 In the conventional automatic door described above, since the rail of the lower frame is formed in a concave groove shape from the floor surface, when a woman wearing high heels passes through the automatic door, the tip of the heel becomes the rail of the lower frame. In some cases, they could fall over and the heel could be damaged. In addition, dust easily collects in the rail and cannot be easily cleaned. Therefore, the present applicant has developed an upper suspension door in which the rail of the lower frame is not a concave groove but a convex rail and has filed a patent application (Japanese Patent Application No. 2003-300786).
JP 2002-70399 A

下枠のレールを凸状のレールにする場合、レールが床面から突出するようでは却って通行の妨げとなるから、レールの高さは極力低くする必要がある。そうすると、障子下部のガイド性が凹溝状のレールに比べて劣ることとなって、移動時に障子が横振れしたり、閉鎖時に障子が強風によって煽られやすくなるといった不都合があった。本発明は以上に述べた実情に鑑みて成されたものであって、移動時に戸が横振れせず、閉鎖時に強い風が吹いても戸が煽られ難く、しかも下枠が歩行者や車椅子の通行の妨げとならない上吊引戸の提供を目的とする。 When the rail of the lower frame is a convex rail, it is necessary to make the height of the rail as low as possible because the rail protrudes from the floor surface, which hinders traffic. If it does so, the guide property of the lower part of a shoji will be inferior compared with a groove-shaped rail, and there was an inconvenience that the shoji would sway when moving, or that the shoji would be easily beaten by a strong wind when closed. The present invention has been made in view of the above-described circumstances, and the door does not shake when moving, and the door is difficult to beat even when a strong wind blows when closed, and the lower frame is a pedestrian or wheelchair. The purpose is to provide a suspended sliding door that does not hinder traffic.

上記の課題を達成するために、請求項１記載の発明による上吊引戸は、下枠と戸を備え、下枠は凸状のレールを有し、戸の下部には振れ止めを設けてあり、振れ止めは、レール上を走行する戸車と、戸車の室内側と室外側に設けた突部とを有し、突部は戸車より下方に突出してレールの室内側と室外側に位置しており、且つ、振れ止めはバネにより下方に付勢してあり、下枠は、戸の閉鎖時における振れ止めの下方位置に振れ止めの突部を収納する凹部を有し、レールは、戸が閉鎖した際に振れ止めが下方に移動できるように、凹部に隣接した部分が凹部に向かって下方に傾斜していることを特徴とする。 In order to achieve the above object, an upper sliding door according to the invention of claim 1 includes a lower frame and a door, the lower frame has a convex rail, and a steady rest is provided at the lower part of the door, The steady rest has a door running on the rail, and a protrusion provided on the indoor side and outdoor side of the door wheel, and the protrusion protrudes downward from the door wheel and is positioned on the indoor side and outdoor side of the rail. In addition, the steady rest is biased downward by a spring, the lower frame has a recess for storing the projection of the steady rest at a position below the steady rest when the door is closed, and the rail is closed by the rail. In this case, a portion adjacent to the recess is inclined downward toward the recess so that the steady rest can move downward.

さらに請求項２記載の発明による上吊引戸は、下枠は、レールの幅が戸車の幅より大きく、レールの室内側と室外側に突部と対向する平坦面を有すると共に、室内側と室外側の縁部に向かって上方に傾斜する傾斜面を有し、室内側と室外側の縁部の高さがレールと略同じ高さとなっていることを特徴とする。 Further, in the upper hanging door according to the invention of claim 2, the width of the rail is larger than the width of the door wheel, the lower frame has a flat surface facing the protrusion on the indoor side and the outdoor side of the rail, and the indoor side and the outdoor side. It has the inclined surface which inclines upward toward the edge part of this, and the height of the edge part of an indoor side and an outdoor side is substantially the same height as a rail, It is characterized by the above-mentioned.

請求項１記載の発明による上吊引戸は、振れ止めの突部が戸車より下方に突出して下枠の凸状のレールの室内側と室外側に位置し、且つ振れ止めはバネにより下方に付勢してあるので、戸の下部が振れ止めにより凸状のレールに確実に案内され、移動時の戸の横振れを防止できると共に、閉鎖時には振れ止めの突部が下枠の凹部に収納されるため、強風を受けても戸が煽られ難い。また、レールの凹部に隣接した部分が凹部に向かって下方に傾斜していることで、戸の開閉に伴って振れ止めの突部が下枠の凹部に出入りし、簡便且つ確実に振れ止めの機能が発揮される。さらに、下枠のレールを凸状にしたので、従来の下枠のように、戸を案内するための凹溝にハイヒールが嵌り込む、ゴミが溜まるといった不都合を解消できる。 The upper suspension sliding door according to the first aspect of the present invention is such that the projection of the steady rest protrudes downward from the door wheel and is located on the indoor side and the outdoor side of the convex rail of the lower frame, and the steady rest is biased downward by a spring. As a result, the lower part of the door is reliably guided to the convex rail by the steadying, preventing the lateral swinging of the door during movement, and the projection of the steadying is housed in the concave part of the lower frame when closed. Therefore, it is difficult for the doors to be beaten even under strong winds. In addition, since the portion adjacent to the concave portion of the rail is inclined downward toward the concave portion, the projection of the steady rest enters and exits the concave portion of the lower frame as the door is opened and closed, so that the steady rest can be easily and reliably performed. Function is demonstrated. Furthermore, since the rail of the lower frame is convex, it is possible to eliminate the inconveniences such as high heels being fitted into the concave grooves for guiding the door and accumulation of dust, as in the conventional lower frame.

請求項２記載の発明によれば、振れ止めとレール間のガイド性を良好に維持しながら、下枠の段差を小さくすることができ、下枠のレールが歩行者や車椅子の通行の妨げとなるのを防止できる。また下枠が、室内側と室外側の縁部に向かって上方に傾斜する傾斜面を有していることで、下枠にゴミが溜まり難い上に清掃も容易に行える。 According to the invention described in claim 2, while maintaining good guide performance between the steady rest and the rail, the step of the lower frame can be reduced, and the rail of the lower frame prevents the passage of pedestrians and wheelchairs. Can be prevented. Further, since the lower frame has an inclined surface that is inclined upward toward the indoor and outdoor edges, it is difficult for dust to collect in the lower frame and cleaning can be easily performed.

以下、本発明の実施の形態を図面に基づいて説明する。図６は、本発明の上吊引戸の一実施形態であって、店舗等の出入口に設置される両開きの自動ドアに適用した場合を示している。この自動ドアは、両脇に固定障子１１，１１を備え、中央側に２枚の可動障子２，２を備え、可動障子２は、センサーが人を検知すると互いに離反するように両側に移動して固定障子１１に重なり、一定の時間が経つと自動的に閉鎖する。可動障子２は、上部に設けた上戸車１２を、上枠１３内に設けた上向きのレール１４に引っ掛けて吊下げ、上枠１３，下枠１間に移動自在に保持され、上枠１３内に設けたリニアモータ等の駆動機構（図示省略）により開閉駆動される。なお、可動障子２を上枠のレール１４に吊下げている部分の構造、障子の駆動機構については、本発明の特徴部分ではなく、公知の構成によるものである。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 6 is an embodiment of the upper sliding door of the present invention, and shows a case where the present invention is applied to a double door automatic door installed at an entrance of a store or the like. This automatic door has fixed shojis 11 and 11 on both sides, and has two movable shojis 2 and 2 on the center side. The movable shoji 2 moves to both sides so as to be separated from each other when the sensor detects a person. It overlaps with the fixed shoji 11 and automatically closes after a certain time. The movable shoji 2 is hung by hanging an upper door 12 provided in the upper part on an upward rail 14 provided in an upper frame 13, and is movably held between the upper frame 13 and the lower frame 1. It is driven to open and close by a drive mechanism (not shown) such as a linear motor provided in. It should be noted that the structure of the portion where the movable shoji 2 is suspended from the rail 14 of the upper frame and the drive mechanism of the shoji are not characteristic portions of the present invention but are of a known configuration.

下枠１は、図４（ｃ）に示すように、室内外方向の中央部に凸状のレール３を備え、レール３上面の高さは下枠の室内側と室外側の縁部と略同じ高さとなっている。レール３を挟んで両側には平坦面９，９を形成してあり、平坦面９，９から室内外縁部にかけては上向きに傾斜する傾斜面１０，１０となっている。下枠１は、図１（ｂ）等に示すように、床面１５に形成した溝に埋め込んで設置され、床面１５からレール３がほとんど突出せず、下枠上面の段差も小さいものとなっている。下枠１をこのように形成したことで、従来の自動ドアのように、通過時にハイヒールが下枠の凹溝に嵌り込むことがなく、レール３が歩行者や車椅子の通過の妨げになることもない上に、下枠１にゴミが溜まり難く、傾斜面１０を有しているので清掃も容易に行える。 As shown in FIG. 4C, the lower frame 1 includes a convex rail 3 at the center in the indoor / outdoor direction, and the height of the upper surface of the rail 3 is substantially the same as the indoor side of the lower frame and the edge of the outdoor side. It is the same height. Flat surfaces 9 and 9 are formed on both sides of the rail 3, and inclined surfaces 10 and 10 are inclined upward from the flat surfaces 9 and 9 to the outer edge of the room. As shown in FIG. 1B and the like, the lower frame 1 is embedded in a groove formed in the floor 15, the rail 3 hardly protrudes from the floor 15, and the step on the upper surface of the lower frame is small. It has become. By forming the lower frame 1 in this way, the high heel does not fit into the concave groove of the lower frame when passing, unlike the conventional automatic door, and the rail 3 prevents the pedestrian or wheelchair from passing. In addition, it is difficult for dust to collect in the lower frame 1 and the inclined surface 10 makes it easy to clean.

可動障子２は、図６に示すように、下框１６内部の戸先側と戸尻側の二箇所に、下枠のレール３に係合する振れ止め４を設けてあり、さらに戸先側の端部には、可動障子２を閉鎖状態でロックするためのロック機構１７を備えている。振れ止め４は、滑りの良い硬質樹脂等によって形成され、図１と図２に示すように、下框１６内に固定したケース体１８内に上下動可能に収容され、バネ７により下方に付勢してある。また振れ止め４は、室内外方向の中央部に下面側より溝１９が形成され、その溝内にレール３上を走行する戸車５を配置してある。さらに戸車５の室内側と室外側には、図１（ｂ）に示すように突部６が形成され、突部６は戸車５よりも下方に突出してレール３の室内側と室外側に位置し、突部６の下面が下枠１の平坦面９と隙間を空けて対向している。レール３の横幅は戸車５の横幅よりも大きく、戸車５自体がレール３にガイドされるものではなく、突部６，６の内側面がレール３の外側面にガイドされるため、振れ止め４とレール３間のガイド性が良好で、可動障子２の開閉時の横振れを確実に防止でき、しかも動きがスムーズとなる。さらに戸車５は、図１に示すように周囲の角部を斜めに面取りして山形に形成することで、レール３との接触面積が小さくなって動きが一層スムーズとなっており、また、可動障子２が強風を受けてバタついたときでも、振れ止め４が浮き上がるのを防止し、突部６がレール３から外れるのを防止できる。 As shown in FIG. 6, the movable shoji 2 is provided with steady rests 4 that engage with the rail 3 of the lower frame at two locations on the door tip side and the door bottom side inside the lower heel 16. A locking mechanism 17 for locking the movable shoji 2 in the closed state is provided at the end of the. The steady rest 4 is formed of a hard resin or the like having good sliding property, and is housed in a case body 18 fixed in the lower collar 16 so as to be vertically movable as shown in FIGS. It is energized. Further, the steady rest 4 has a groove 19 formed in the central portion in the indoor / outdoor direction from the lower surface side, and a door 5 running on the rail 3 is disposed in the groove. Further, as shown in FIG. 1B, a protrusion 6 is formed on the indoor side and the outdoor side of the door 5, and the protrusion 6 protrudes below the door 5 and is positioned on the indoor side and the outdoor side of the rail 3. The lower surface of the protrusion 6 is opposed to the flat surface 9 of the lower frame 1 with a gap. Since the width of the rail 3 is larger than the width of the door 5, the door 5 itself is not guided by the rail 3, and the inner surfaces of the protrusions 6 and 6 are guided by the outer surface of the rail 3. And the guide 3 between the rails 3 is good, the horizontal swing when the movable shoji 2 is opened and closed can be surely prevented, and the movement is smooth. Furthermore, as shown in FIG. 1, the door wheel 5 is formed in a mountain shape by obliquely chamfering the surrounding corners, so that the contact area with the rail 3 is reduced and the movement is further smoothed. Even when the shoji 2 receives a strong wind and flutters, the steady rest 4 can be prevented from rising and the protrusion 6 can be prevented from coming off the rail 3.

さらに、図５と図６に示すように、固定障子下框２０の召し合せ側の端部の室内側面にガイド部材２１が取付けてあり、これに対向して可動障子２の室内側の床面にガイドローラ２２を固定設置してあり、ガイド部材２１とガイドローラ２２とで可動障子の下框１６を前後から挟んで保持することによっても、可動障子２の横振れを防止している。 Further, as shown in FIGS. 5 and 6, a guide member 21 is attached to the indoor side surface of the end portion on the calling side of the stationary shoji 20, and the indoor floor surface of the movable shoji 2 is opposed to the guide member 21. The guide roller 22 is fixedly installed, and the horizontal swing of the movable shoji 2 is also prevented by holding the lower arm 16 of the movable shoji from the front and back by the guide member 21 and the guide roller 22.

また下枠１は、可動障子２の閉鎖位置における戸先側の振れ止め４とロック機構１７の下方に位置する部分が、図４（ａ）に示すように、四角い孔２３を明けて室内外の平坦面９とレール３を切除してあり、その孔２３内に、振れ止め４及びロック機構１７の受け部材２４を設置してある。受け部材２４は、図２と図３（ａ）に示すように、可動障子２が閉鎖位置にあるときに振れ止め４の突部６を収納する凹部８と、シリンダーやサムターンの操作によりロック機構１７の下面に出没するストライク２５の受け穴２６とを有している。レール３は、可動障子２が閉鎖したときに突部６が下方に移動して凹部８に落ち込み、且つ可動障子２が開くときには突部６が上方に移動して凹部８から脱するように、凹部８の可動障子２の開き側に隣接する部分に、凹部８に向かって下方に傾斜する傾斜部２７を設けてある。下枠１の平坦面９と凹部８の底面との間にも、同じように傾斜部２８を設けてある。 In addition, the lower frame 1 is formed so that a portion positioned below the doorway side steady rest 4 and the lock mechanism 17 in the closed position of the movable shoji 2 opens a square hole 23 as shown in FIG. The flat surface 9 and the rail 3 are cut out, and the steady rest 4 and the receiving member 24 of the lock mechanism 17 are installed in the hole 23. As shown in FIGS. 2 and 3A, the receiving member 24 includes a recess 8 that houses the projection 6 of the steady rest 4 when the movable shoji 2 is in the closed position, and a lock mechanism that is operated by operating a cylinder or thumb turn. 17 and a receiving hole 26 of the strike 25 that appears and disappears on the lower surface of the member 17. The rail 3 is configured such that when the movable shoji 2 is closed, the projection 6 moves downward and falls into the recess 8, and when the movable shoji 2 is opened, the projection 6 moves upward and comes out of the recess 8. An inclined portion 27 that is inclined downward toward the recessed portion 8 is provided at a portion adjacent to the opening side of the movable shoji 2 of the recessed portion 8. An inclined portion 28 is similarly provided between the flat surface 9 of the lower frame 1 and the bottom surface of the recess 8.

下枠１が上記のように構成してあるので、可動障子２が閉鎖位置にあるときには、図１（ａ）に示すように振れ止め４の突部６が下枠１の凹部８に落ち込むため、ロック機構１７のストライク２５を受け穴２６に挿入して可動障子２をロックしているときはもとより、ロックしていないときでも、可動障子２が強風によって煽られるのを確実に防止できる。可動障子２が開くときには、振れ止め４の戸車５が傾斜部２７に乗り上げることで振れ止め４が上方に移動し、振れ止め４が下枠のレール３にガイドされる。 Since the lower frame 1 is configured as described above, when the movable shoji 2 is in the closed position, the protrusion 6 of the steady rest 4 falls into the recess 8 of the lower frame 1 as shown in FIG. In addition, when the movable shoji 2 is locked by inserting the strike 25 of the lock mechanism 17 into the receiving hole 26, it is possible to reliably prevent the movable shoji 2 from being beaten by a strong wind. When the movable shoji 2 is opened, the steady rest 4 is moved upward by the door 5 of the steady rest 4 riding on the inclined portion 27, and the steady rest 4 is guided by the rail 3 of the lower frame.

本発明は、以上に述べた実施形態に限定されない。可動障子が一枚の、片引きの自動ドアとすることもできる。また本発明の上吊引戸は、障子の駆動機構を有する自動ドアに限らず、障子を手動で開閉するものにも適用できる。 The present invention is not limited to the embodiments described above. It can also be a one-way automatic door with one movable shoji. The upper sliding door of the present invention is not limited to an automatic door having a shoji drive mechanism, and can be applied to a door that manually opens and closes the shoji.
