例えば、引戸装置として、左右の竪枠と、溝付き上枠と、レール付き下枠とから枠組された図示しない構造物に建込み装着された枠体には、左右の竪框と、上框と、戸車付き下框とから枠組み形成された引戸（例えば特許文献１）を設けたものが知られている。ところで、このような戸車付き下框を用いるものでは、下枠の上部にレールが突出するため、高齢者世帯等では、該レールに躓いたり、挟まったりするなどの虞があり、また、車椅子等を使用すると通り難いという問題がある。 For example, as a sliding door device, a frame body built and mounted on a structure (not shown) framed from left and right frame, a grooved upper frame, and a rail-equipped lower frame, And what provided the sliding door (for example, patent document 1) by which the framework was formed from the lower armor with a door pulley is known. By the way, in such an undercarriage with a door wheel, the rail protrudes from the upper part of the lower frame, so in elderly households, etc., there is a risk of crawling or getting caught in the rail. When using, there is a problem that it is difficult to pass.

そこで、枠を平坦にするために、図２３に示すような引戸装置が開発されている。この引戸装置では、下枠のレール受枠101には、長さ方向の溝部102を形成し、この溝部102に複数の昇降体103を出没自在に設け、これら昇降体103の幅方向両側上部にそれぞれ長さ方向の係合溝104，104を形成すると共に、前記引戸105の下枠に前記両係合溝104，104に係入する長さ方向のレール枠106を設け、前記昇降体103は引戸105を閉める方向（図２３中矢印方向）の前側の昇降体103の後部に、係合凹部107を設け、この係合凹部107に係合する突起状の係合部108を、後側の昇降体103の前部に設けている。 Therefore, in order to make the frame flat, a sliding door device as shown in FIG. 23 has been developed. In this sliding door device, the rail receiving frame 101 of the lower frame is formed with a groove portion 102 in the length direction, and a plurality of elevating bodies 103 are provided in the groove portion 102 so as to be able to protrude and retract, respectively. Longitudinal engaging grooves 104, 104 are formed, and a longitudinal rail frame 106 is provided on the lower frame of the sliding door 105 to engage with the engaging grooves 104, 104. An engagement recess 107 is provided in the rear part of the front elevating body 103 in the direction of closing 105 (in the direction of the arrow in FIG. 23), and the protrusion-like engagement part 108 that engages with the engagement recess 107 is moved upward and downward. It is provided at the front of the body 103.

この引戸装置では、図２３に示すように、引戸105を閉めると、前側の昇降体103の後部が上昇し、この前側の昇降体103の前記係合溝104にレール枠106が係入することにより、前側の昇降体103が水平に上昇し、引戸105の移動により順次前側の昇降体103が上昇し、それら昇降体103により引戸105の下枠とレール受枠101との隙間が塞がれ、逆に、引戸105を図２３右側に移動すると、自重により昇降体103が溝部102内に没し、昇降体103の上面とレール受枠101の上面とが面一となり、車椅子等を安全に通すことができる。また、建物開口部に架設した上部レールと下部レール溝との間に、横方向走行自在な横引き開閉戸を設置するに、上記下部レール溝に上下並行移動固定自在な底部を内装し、横引き開閉戸の開放時に上記底部が床面と同一面となるように構成した横引き開閉戸の下部レール溝（特許文献２）があり、この引戸では長尺アングル部材にリンク機構を配設している。

In addition, an engagement groove 65 that is an engagement portion with which the dust removal tool is engaged is formed in the upper portion of the lid 61. Since the engaging groove 65 is formed obliquely with respect to the horizontal, even if the dust removal tool is flat, it can be removed by inserting it and lifting it upward. The lid 61 is made of a synthetic resin or the like, and preferably has an elasticity such as rubber.

図２，図１０〜図１２に示すように、ごみ取り具71は、硬質合成樹脂などからなり、使用者が把持する操作部72と、前記案内溝22に挿入する案内溝挿入部73と、前記幅広部23に挿入する幅広部挿入部74とを一体に備え、この幅広部挿入部74の下縁は９０度以下の掻き取り縁75に形成されている。また、その幅広部挿入部74の上下寸法は前記幅広部23の高さより狭い。 As shown in FIGS. 2 to 10, the dust removal tool 71 is made of a hard synthetic resin or the like, and includes an operation unit 72 that is gripped by a user, a guide groove insertion unit 73 that is inserted into the guide groove 22, A wide portion insertion portion 74 to be inserted into the wide portion 23 is integrally provided, and the lower edge of the wide portion insertion portion 74 is formed as a scraping edge 75 of 90 degrees or less. Further, the vertical dimension of the wide portion insertion portion 74 is narrower than the height of the wide portion 23.

次に前記構成につき、その作用を説明すると、まず、引戸２が開くと、固定下枠１Ｄには、案内溝22があるだけで、床面Ｙと固定下枠１Ｄとが平坦に形成されているから、車椅子等の通行をスムーズに行うことができ、かつ歩行においても邪魔になる部分がない。また、引戸２が開閉すると、レール板12が案内溝22内に沿って移動するため、安定して引戸２が開閉する。この場合、レール板12の下端の両側は、低摩擦材12Ａが位置しているから、レール板12が案内板部32，33に当たってもスムーズに摺動することができる。そして、引戸２を閉めた状態では、引戸２と固定下枠１Ｄとの間がレール板12により塞がれるため、外部からの風，雨，埃等の侵入を防止でき、さらに、防火機能も向上する。 Next, the operation of the above configuration will be described. First, when the sliding door 2 is opened, the fixed lower frame 1D has only the guide groove 22, and the floor surface Y and the fixed lower frame 1D are formed flat. Therefore, it is possible to smoothly pass a wheelchair or the like, and there is no part that disturbs walking. When the sliding door 2 opens and closes, the rail plate 12 moves along the guide groove 22, so that the sliding door 2 opens and closes stably. In this case, since the low friction material 12A is positioned on both sides of the lower end of the rail plate 12, even if the rail plate 12 hits the guide plate portions 32 and 33, it can slide smoothly. When the sliding door 2 is closed, the space between the sliding door 2 and the fixed lower frame 1D is blocked by the rail plate 12, so that intrusion of wind, rain, dust and the like from the outside can be prevented, and a fire prevention function is also provided. improves.

また、外部から案内溝22内にごみが侵入しても、引戸２を開閉すると、レール板12の端部に掻上げ部15が設けられているため、この掻上げ部15により、案内溝22のごみを上方に掻上げ、これにより、ごみが案内溝22に溜まることを防止できる。したがって、引戸２を開閉する毎に、案内溝22におけるごみの堆積を防止できる。 Further, even if dust enters the guide groove 22 from the outside, when the sliding door 2 is opened and closed, the scraping portion 15 is provided at the end of the rail plate 12. The waste is scraped upward, so that the dust can be prevented from collecting in the guide groove 22. Therefore, every time the sliding door 2 is opened and closed, dust accumulation in the guide groove 22 can be prevented.

本発明の特徴として、外部から案内溝22内に水が侵入しても、この水は幅の狭い案内溝22からその下部に位置する幅の広い幅広部23に落下し、幅広部23の底板部35に穿設した水抜き孔25からスムーズに排水される。特に、比較的細くすることが好ましい案内溝22においては、両側の案内板部32，33間における毛細管現象により、底部に小さな穴を開設しても、排水がスムーズに行われず、一度に多量の水が流れ込むと水が溢れてしまうが、案内溝22の下部に幅広部23を設けることにより、案内溝22に流れ込んだ水は抵抗なく、幅広部23の底部に流れ、水抜き孔25より自然流下により排水される。 As a feature of the present invention, even when water enters the guide groove 22 from the outside, the water falls from the narrow guide groove 22 to the wide wide portion 23 located below the narrow guide groove 22, and the bottom plate of the wide portion 23 The water is smoothly drained from the drain hole 25 formed in the portion 35. In particular, in the guide groove 22 that is preferably relatively thin, even if a small hole is formed in the bottom due to the capillary phenomenon between the guide plates 32 and 33 on both sides, the drainage is not smoothly performed, and a large amount of When water flows in, the water overflows, but by providing the wide portion 23 at the lower portion of the guide groove 22, the water flowing into the guide groove 22 flows without resistance and flows to the bottom of the wide portion 23, and naturally flows from the drain hole 25. It is drained by flowing down.

また、本発明の特徴として、幅広部23内にごみが溜まったら、固定枠体21の長さ方向端部に位置する挿入溝51から、蓋体61を取り外し、この場合、蓋体61の係合溝65に、ごみ取り具71の幅広部挿入部74側を挿入して引き上げることにより、ごみ取り具71を用いて蓋体61を取り外すことができる。蓋体61を挿入溝51から取り外したら、ごみ取り具71の幅広部挿入部74を幅広部23に挿入し、案内溝挿入部73を前記案内溝22に合わせ、固定枠体21の長さ方向にごみ取り具71を移動して、ごみを長さ方向両側の挿入溝51側に集め、外部に排出する。この場合、掻き取り縁75を幅広部23の底面に沿わせるようにすることにより、ごみを効果的に集めることができる。 Further, as a feature of the present invention, when dust accumulates in the wide portion 23, the lid 61 is removed from the insertion groove 51 located at the end in the length direction of the fixed frame 21, and in this case, the lid 61 is engaged. The lid 61 can be removed using the dust remover 71 by inserting and pulling up the wide part insertion portion 74 side of the dust remover 71 into the joint groove 65. When the lid 61 is removed from the insertion groove 51, the wide portion insertion portion 74 of the dust remover 71 is inserted into the wide portion 23, the guide groove insertion portion 73 is aligned with the guide groove 22, and the length of the fixed frame 21 is increased. The dust collector 71 is moved to collect the dust on the insertion groove 51 side on both sides in the length direction and discharge it to the outside. In this case, by making the scraping edge 75 along the bottom surface of the wide portion 23, it is possible to effectively collect dust.

さらに、本発明の特徴として、固定枠体21は、案内溝22と幅広部23とを形成する部分が、板材に自由端のない連続した枠体構造をなし、すなわち案内板部32，案内板部33，底板部35，上板部36及び連結板部37が連続した枠体構造をなすから、上面板部30，31に荷重を受けても、細い案内溝22を有する固定枠体21が変形することなく、構造上、高い強度を得ることができる。 Further, as a feature of the present invention, the fixed frame 21 has a continuous frame structure in which the portion forming the guide groove 22 and the wide portion 23 has no free end in the plate material, that is, the guide plate portion 32 and the guide plate. Since the portion 33, the bottom plate portion 35, the upper plate portion 36, and the connecting plate portion 37 form a continuous frame structure, the fixed frame body 21 having the thin guide groove 22 is formed even when a load is applied to the upper surface plate portions 30, 31. High strength can be obtained structurally without deformation.

また、図１などにおいて、一側方から風が吹いてきて、上から案内溝22内に吹き込んでも、該案内溝22より広い幅広部23において流れが止まるため、風が案内溝22を上昇して他側に流れることがなく、水抜き孔25から外部に抜ける。また、風が強い場合は、引戸２が傾動し、レール板12が案内板部33に接するから、風の進入を防止できる。したがって、引戸２の下部から内部に雨風が吹き込むことがない。ところで、仮に引戸２の幅が１８０ｃｍで、固定下枠１Ｄの上面部24と引戸２の下部の間隔が１ｃｍとすれば、このように間隔が僅かでも、引戸２と固定下枠１Ｄとの間には、１８０ｃｍ2もの隙間が存在することになる。これに対して、本願発明では、案内溝22とレール12により前記隙間を塞ぐから、引戸２内外における熱の移動を防止し、暖房及び冷房損失を大幅に削減することができる。 Further, in FIG. 1 and the like, even if wind blows from one side and blows into the guide groove 22 from above, the flow stops at the wide portion 23 wider than the guide groove 22, so that the wind rises up the guide groove 22. And does not flow to the other side, and comes out from the drain hole 25 to the outside. In addition, when the wind is strong, the sliding door 2 tilts and the rail plate 12 comes into contact with the guide plate portion 33, so that the wind can be prevented from entering. Therefore, rain wind does not blow into the inside from the lower part of the sliding door 2. By the way, if the width of the sliding door 2 is 180 cm and the distance between the upper surface portion 24 of the fixed lower frame 1D and the lower portion of the sliding door 2 is 1 cm, the gap between the sliding door 2 and the fixed lower frame 1D is small even in this way. There will be a gap of 180 cm2. On the other hand, in this invention, since the said clearance gap is block | closed by the guide groove 22 and the rail 12, the movement of the heat inside and outside the sliding door 2 can be prevented, and heating and cooling loss can be reduced significantly.

このように本実施例では、請求項１に対応して、固定下枠１Ｄに沿って引戸２を開閉可能に設け、固定下枠１Ｄに案内溝22を形成し、この案内溝22に挿入するレール板12を引戸２に設けた引戸装置において、固定下枠１Ｄには案内溝22の下部に該案内溝22より幅の広い幅広部23を設け、この幅広部23の底部に水抜き孔25を設けたから、案内溝22はごみの侵入や歩行時の邪魔にならないように細くすることが好ましく、案内溝22を細くすると毛細管現象により排水がスムーズに行われず、一度に多量の水が流れ込むと水が溢れる虞があるが、案内溝22の下部に幅広部23を設けることにより、案内溝22に流れ込んだ水は抵抗なく、幅広部23の底部へと流れ、水抜き孔25よりスムーズに排水される。 Thus, in this embodiment, corresponding to claim 1, the sliding door 2 is provided so as to be openable and closable along the fixed lower frame 1D, the guide groove 22 is formed in the fixed lower frame 1D, and the guide groove 22 is inserted.

Therefore, it is preferable to narrow the guide groove 22 so that it does not get in the way of intrusion or walking, and if the guide groove 22 is narrowed, drainage will not be performed smoothly due to capillary action, and a large amount of water will flow in at once. Although there is a risk of water overflow, by providing the wide portion 23 at the lower part of the guide groove 22, the water flowing into the guide groove 22 flows to the bottom of the wide portion 23 without resistance and drains smoothly from the drain hole 25. Is done.

また、このように本実施例では、請求項２に対応して、固定下枠１Ｄは、案内溝22の両側に位置する案内板部32，33と、これら両側の案内板部32，33の下端を連結し幅広部23を形成する幅広形成枠板部34とを備えるから、両側の案内板部32，33を幅広形成枠板部34により連結した枠体構造をなすため、通行などにより固定下枠１Ｄの上面に荷重が加わっても、細い案内溝を有する固定下枠が変形することなく、構造上、高い強度を得ることができる。 In this way, in this embodiment, corresponding to claim 2, the fixed lower frame 1D includes the guide plate portions 32, 33 located on both sides of the guide groove 22 and the guide plate portions 32, 33 on both sides.
