Description

本発明は、住宅等の建築物の開口部に使用される引き戸構造に関する。 The present invention relates to a sliding door structure used for an opening of a building such as a house.

従来、図６に示すように、住宅等建築物の開口部に使用される引き戸において、上枠１２、下枠１３、左右縦枠１４間に戸板１６が水平移動可能なようにして設けられ、前記左右縦枠１４間に中縦枠１５が設けられ、中縦枠１５と左右いずれかの縦枠１４との間に開口部Ｋが設けられた構造の引き戸構造体１１において、前記中縦枠１５の木口面１５ａと戸板１６の表面との間には所定寸法の隙間が設けられ、戸板１６の開閉時、戸板１６が水平移動する際、中縦枠１５の木口面１５ａと戸板１６の表面とが接触することによる開閉障害を防止している。この隙間は戸板１６の開閉をスムーズに行うためには有効であるが、時として、明かり漏れの恐れがあり、このことが大きな問題点となっていた。 Conventionally, as shown in FIG. 6, in a sliding door used for an opening of a building such as a house, a door plate 16 is provided so as to be horizontally movable between the upper frame 12, the lower frame 13, and the left and right vertical frames 14, In the sliding door structure 11 having a structure in which a middle vertical frame 15 is provided between the left and right vertical frames 14 and an opening K is provided between the middle vertical frame 15 and one of the left and right vertical frames 14, the middle vertical frame 15 is provided with a gap of a predetermined dimension between the front face 15a of the door 15 and the surface of the door plate 16. When the door board 16 moves horizontally when the door board 16 is opened and closed, the front face 15a of the middle vertical frame 15 and the surface of the door board 16 are provided. This prevents opening and closing troubles caused by contact with. This gap is effective for smoothly opening and closing the door plate 16, but sometimes there is a risk of light leakage, which is a big problem.

この明かり漏れを解消するため、隙間を塞ぐための部材１７を中縦枠１５の木口面１５ａの高さ方向に取り付け、中縦枠１５の木口面１５ａと戸板１６の表面との隙間をなるべく小さくし明かりが漏れるのを防止していた。 In order to eliminate this light leakage, a member 17 for closing the gap is attached in the height direction of the bottom face 15a of the middle vertical frame 15, and the gap between the bottom face 15a of the middle vertical frame 15 and the surface of the door plate 16 is made as small as possible. The light was prevented from leaking.

ところが、特に木製の戸板においては、取り付け使用する部屋の環境によっては、湿気を吸湿したり、また、放湿したりを繰り返すと、戸板１６自体の高さ方向、幅方向の反りが発生することが多々あり、せっかく取り付けた前記隙間を塞ぐ部材１７が有効に働かなくなるといった問題点があった。すなわち、戸板１６の高さ方向の略中央部が前記中縦枠１５の木口面１５ａと離間する方向に反りが発生すると、中縦枠１５の木口面１５ａと戸板１６の表面との間の隙間が大きくなり明かり漏れが防止できなくなる。また、逆に、戸板１６の高さ方向の略中央部が前記中縦枠１５の木口面１５ａに近づく方向に反りが発生すると、中縦枠１５の木口面１５ａと戸板１６の表面との間の隙間が小さくなり、隙間防止部材が戸板表面に強く接触し、これが原因で戸板１６の開閉障害となっていた。 However, particularly in the case of wooden doorboards, depending on the environment of the installation and use, if moisture is absorbed or released repeatedly, warping in the height direction and width direction of the doorboard 16 itself may occur. There are many problems, and there is a problem that the member 17 that closes the attached gap does not work effectively. That is, when a warp occurs in a direction in which a substantially central portion in the height direction of the door plate 16 is separated from the front end 15a of the middle vertical frame 15, a gap between the front end 15a of the middle vertical frame 15 and the surface of the door plate 16 is generated. Becomes larger and light leakage cannot be prevented. On the other hand, if warpage occurs in the direction in which the substantially central portion in the height direction of the door plate 16 approaches the front end 15a of the middle vertical frame 15, the space between the front end 15a of the middle vertical frame 15 and the surface of the door plate 16 is increased. The gap is reduced, and the gap preventing member is in strong contact with the surface of the door plate, which causes the door plate 16 to open and close.

そこで、引き戸との隙間を塞ぐ部材を中方立の木口で引き戸対向面に出没を調整可能に取り付け、中縦枠の木口面と戸板の表面との間の隙間の寸法の大小にうまく対応する構造とした引き戸構造の記載がある。（例えば、特許文献１参照）。 Therefore, a member that closes the gap with the sliding door is attached to the sliding door facing surface with a neutral wooden mouth so that the protrusion and depression can be adjusted, and the structure that copes well with the size of the gap between the wooden mouth face of the middle vertical frame and the surface of the doorboard There is a description of the sliding door structure. (For example, refer to Patent Document 1).

特開２００２−２５０１８０号公報（第１−５頁、第１−３図）JP 2002-250180 A (page 1-5, FIG. 1-3)

しかしながら、上記従来技術のなかで、特開２００２−２５０１８０号公報に記載されている隙間調整機構付き引き戸構造においては、略く字形状の屈曲部を備えた弾性プレートを方立に形成された溝内に設け、方立の側面からネジの操作で前記略く字形状の屈曲部を備えた弾性プレートの頂部が押圧され、それと連動して前記略く字形状の屈曲部を備えた弾性プレートの屈曲部が開脚又は閉脚し、溝内の深さ方向に伸縮し、該伸縮によって、隙間部材が方立の溝から出没する構造であり、構造自体が複雑で、あらかじめ方立製造時に工場生産ラインで前記略く字形状の屈曲部を備えた弾性プレート及び隙間封止部材等を方立の所定位置に組み込んで完成品として施工現場へ納入することになる。このように、構造自体が複雑であるために、コスト的にも高いものに付くといった問題点があった。 However, in the sliding door structure with a gap adjusting mechanism described in Japanese Patent Application Laid-Open No. 2002-250180 among the above-described prior art, a groove formed in an upright manner with an elastic plate having a substantially square-shaped bent portion. The top of the elastic plate provided with the substantially square-shaped bent portion is pressed by a screw operation from a side surface of the vertical, and the elastic plate provided with the substantially square-shaped bent portion is interlocked with this. The bent part opens or closes, expands and contracts in the depth direction in the groove, and the expansion and contraction causes the gap member to appear and disappear from the vertical groove. The elastic plate, the gap sealing member, and the like provided with the substantially square-shaped bent portion in the line are assembled at a predetermined position in a vertical position and delivered to the construction site as a finished product. As described above, since the structure itself is complicated, there is a problem that it is expensive.

There was also.

また、引き戸を長期間使用後、前記隙間封止部材が引き戸表面と接触し摩滅し、新しいものと交換する必要が生じても、施工現場で簡単に取り替えることができないといったメンテナンス上の問題点もあった。 In addition, after the sliding door has been used for a long period of time, even if the gap sealing member comes into contact with the sliding door surface and wears out and needs to be replaced with a new one, there is also a maintenance problem that it cannot be easily replaced at the construction site. there were.

また、上記したような、リフォーム時やメンテナンス時において、古くなって使いものにならなくなった隙間封止部材を再使用することが不可能であり、中縦枠（方立）そのものを工場へ送り、新品の隙間封止部材と交換しなければならず、そのために、引き戸構造体を解体し新たに施工し直すといった手間や費用が大きくかかるといった問題点があった。 In addition, as described above, it is impossible to reuse a gap sealing member that has become unusable at the time of renovation or maintenance, and the middle vertical frame (orientation) itself is sent to the factory. Therefore, there is a problem in that it takes time and cost to disassemble the sliding door structure and re-install it.

図１、図２において、本発明の引き戸構造体１は上枠２、下枠３、左右の縦枠４で四方を囲われた枠が形成され、その枠の左右間口方向の略中程に中縦枠５が上枠２と下枠３の間に上下高さ方向に設けられ、枠体が形成されている。 1 and 2, the sliding door structure 1 of the present invention has a frame surrounded by an upper frame 2, a lower frame 3, and left and right vertical frames 4, and is substantially in the middle of the left and right frontage direction of the frame. A middle vertical frame 5 is provided between the upper frame 2 and the lower frame 3 in the vertical direction, and a frame body is formed.

前記左右の縦枠４のいずれか片方の縦枠４と中縦枠５の間に引き戸の開口部Ｋが形成されている。さらに、必要に応じて、上枠２に上レール（図示せず）が組み込まれ、また、必要に応じて下枠３には下レール（図示せず）が組み込まれている。この上下枠の間で左右縦枠４間を水平に移動する戸板６が設けられている。該戸板６によって前記開口部Ｋが開閉自在に構成されている。また、前記中縦枠５の戸板対向木口面５ａに、戸板６の表面と戸板対向木口面５ａの間に存在する隙間Ｃの大きさを調節するための隙間調整手段７が設けられている。 A sliding door opening K is formed between one of the left and right vertical frames 4 and the middle vertical frame 5. Further, an upper rail (not shown) is incorporated in the upper frame 2 as necessary, and a lower rail (not shown) is incorporated in the lower frame 3 as necessary. A door plate 6 that moves horizontally between the left and right vertical frames 4 is provided between the upper and lower frames. The opening K is configured to be openable and closable by the door plate 6. In addition, a gap adjusting means 7 for adjusting the size of the gap C existing between the surface of the door plate 6 and the door plate facing side face 5a is provided on the door board facing side face 5a of the middle vertical frame 5.

前記隙間Ｃの大きさは大きすぎても、また、小さすぎても戸板６の走行に支障が生じる。すなわち、隙間Ｃが大きすぎると、中縦枠５の戸板対向木口面５ａと戸板６の表面の間から隣室の明かりが漏れるといった支障が生じる。また、隙間Ｃが小さすぎると、戸板６が高さ方向又は幅方向に少しでも反りが発生しただけで、戸板６の表面と中縦枠５の戸板対向木口面５ａとの間で相互に接触し戸板６の開閉操作に支障が生じる。 If the size of the gap C is too large or too small, the door plate 6 will travel. That is, if the gap C is too large, a problem arises in that the light in the adjacent room leaks from between the door plate facing front surface 5 a of the middle vertical frame 5 and the surface of the door plate 6. In addition, if the gap C is too small, the door plate 6 is merely warped in the height direction or the width direction, and contact is made between the surface of the door plate 6 and the door plate facing face 5a of the middle vertical frame 5. There is a problem in the opening / closing operation of the sliding door plate 6.

従って、中縦枠５の戸板対向木口面５ａと戸板６の表面の間に生じる前記隙間Ｃを戸板開閉操作に支障が生じない程度において、ある程度大きめに設定し、且つ、隙間Ｃからの明かり漏れを防止するために隙間調整手段７が戸板対向木口面５ａに取り付けられている。 Therefore, the gap C formed between the door plate facing face 5a of the middle vertical frame 5 and the surface of the door plate 6 is set to a certain extent to the extent that the door plate opening / closing operation is not hindered, and light leakage from the gap C is caused. In order to prevent this, the gap adjusting means 7 is attached to the door-plate facing face 5a.

前記隙間調整手段７は、戸板６の表面と摺れあっても戸板６の表面化粧材を損傷しない程度に柔らかい材質のものが好適である。このように、軟質の部材からなる隙間調整手段７が戸板対向木口面５ａに取り付けられていることによって、戸板６に高さ方向や幅方向の反りが発生しても、中縦枠５の戸板対向木口面５ａと戸板６の表面との距離が開閉に支障がでない程度に大きめに設定され、しかも、明かりが漏れないように、軟質の部材で隙間隠しがされている。 The gap adjusting means 7 is preferably made of a soft material that does not damage the surface decorative material of the door plate 6 even if it slides on the surface of the door plate 6. Thus, even if the warp of the height direction or the width direction occurs in the door plate 6 because the gap adjusting means 7 made of a soft member is attached to the door plate facing face 5a, the door plate of the middle vertical frame 5 is used. The distance between the facing front end surface 5a and the surface of the door plate 6 is set to be large enough not to interfere with opening and closing, and the gap is concealed with a soft member so that the light does not leak.

前記戸板６は例えば合板又は中比重繊維板等の木質材からなる芯材を組み合わせて作製された芯組材（図示せず）の表面裏面に表面化粧材を貼着して作製された、所謂、フラッシュ構造の戸板６が好適である。しかし、前記芯組材を用いたフラッシュ構造でなく、密実構造の戸板６であってもよいものとする。また、前記上枠２、下枠３、左右縦枠４、中縦枠５等の各部材パネルの構造も戸板６と同様のものが好適である。表面化粧材としては、天然銘木からなる突板や単板、木目柄の印刷が施された塩ビ樹脂シートやオレフィン樹脂シート、木目柄の印刷が施された化粧紙等が好適なものとして例示できる。しかし、これらの材料に限られるものではない。 The door panel 6 is a so-called so-called door panel 6 manufactured by sticking a surface decorative material on the front and back surfaces of a core material (not shown) prepared by combining a core material made of wood such as plywood or medium specific gravity fiber board. The door plate 6 having a flash structure is preferable. However, the door plate 6 having a solid structure may be used instead of the flash structure using the core material. The structure of each member panel such as the upper frame 2, the lower frame 3, the left and right vertical frames 4, and the middle vertical frame 5 is preferably the same as that of the door plate 6. Preferable examples of the surface decorative material include a veneer plate or a single plate made of natural wood, a vinyl resin resin sheet or an olefin resin sheet on which a wood grain pattern is printed, and a decorative paper on which a wood grain pattern is printed. However, it is not limited to these materials.

前記戸板６の水平方向の移動手段は、例えば、必要に応じて、上枠２に上レール（図示せず）を取り付け、ガイドランナー（図示せず）を戸板６の上木口に装着し、上吊り方式で走行させ、戸板６の下部は下枠３に必要に応じて下レール（図示せず）を取り付け、戸車（図示せず）を戸板下木口に装着する構造を好適なものの一例として例示できる。また、戸板上部は上吊り方式以外の構造であっても勿論よいものとする。例えば、上枠下端面に鴨居溝を設け、戸板６の上端部に切欠段部を設け該切欠段部によって突出部を形成し該突出部を前記鴨居の溝に差し込む構造であってもよい。また、戸板６の下部は前記戸車方式以外の構造であっても、勿論、よいものとする。例えば、戸板６の下端部木口面に条溝を形成し、下枠３にガイドピン（図示せず）を設け、該ガイドピンが前記条溝内に嵌挿され、ガイドピンを案内として戸板６が左右方向へ走行する構造であってもよい。勿論、これら以外の戸板走行方式であってもよいものとする。 The horizontal moving means of the door plate 6 is, for example, attached with an upper rail (not shown) to the upper frame 2 as necessary, and a guide runner (not shown) mounted on the upper end of the door plate 6.

図３において、本発明の第一実施形態における隙間調整手段７の詳細を説明する。本発明の第一実施形態における隙間調整手段７は、一側面に開口部７ｂが設けられている断面視略コの字型を有する調整枠７ａと、該調整枠７ａの開口部７ｂ側に設けられている軟質部材からなる平板片７ｃと前記調整枠７ａの裏面側に設けられた軟質の弾性部材からなるスペーサーＳと隙間調整手段７を中縦枠５の戸板対向木口面５ａに取り付けるとともに、隙間調整手段７の戸板対向木口面５ａからの突出量Ｔを適当な寸法に調整する働きを持つ調整ネジＮとで構成されている。 In FIG. 3, the details of the gap adjusting means 7 in the first embodiment of the present invention will be described. The gap adjusting means 7 in the first embodiment of the present invention is provided on the side of the opening 7b of the adjusting frame 7a and the adjusting frame 7a having a substantially U-shaped cross-sectional view in which an opening 7b is provided on one side surface. The flat plate piece 7c made of a soft member and the spacer S made of a soft elastic member provided on the back surface side of the adjustment frame 7a and the gap adjusting means 7 are attached to the door plate facing cuff surface 5a of the middle vertical frame 5, The gap adjusting means 7 is composed of an adjusting screw N having a function of adjusting the protruding amount T from the door plate facing front end surface 5a to an appropriate size.

隙間調整手段７は幅が中縦枠５の厚み寸法よりも多少小さめの寸法を有し、中縦枠５の木口面に高さ方向のほぼ全長にわたって取り付けられており、見かけ上、細長い形状をした部材である。前記調整枠７ａは、例えば、硬質又は半硬質の塩ビ樹脂、オレフィン樹脂、アクリル樹脂、ポリエステル樹脂、ポリエチレン樹脂等の成型体である。例えば、押し出し成形等で製造される。形状は上記したように、一側面の長手方向のほぼ全長がスリット状に開口し、開口部７ｂを形成している。このような断面視略コの字型をした部材である。さらに、前記調整枠７ａの開口部７ｂの対向面、すなわち、調整枠７ａの裏面側に調整ネジＮが嵌入される複数個の調整孔Ｈが長手方向（高さ方向）にわたって設けられている。 The gap adjusting means 7 has a width that is slightly smaller than the thickness of the middle vertical frame 5, and is attached to the bottom surface of the middle vertical frame 5 over almost the entire length in the height direction. It is a member. The adjustment frame 7a is, for example, a molded body such as a hard or semi-rigid PVC resin, an olefin resin, an acrylic resin, a polyester resin, or a polyethylene resin. For example, it is manufactured by extrusion molding or the like. As described above, almost the entire length in the longitudinal direction of one side surface opens in a slit shape to form the opening 7b. This is a member having a generally U-shaped cross-sectional view. Further, a plurality of adjustment holes H into which the adjustment screws N are fitted are provided in the longitudinal direction (height direction) on the opposite surface of the opening 7b of the adjustment frame 7a, that is, on the back side of the adjustment frame 7a.

また、前記調整枠７ａの開口部７ｂ側に軟質部材からなる平板片７ｃが取り付けられている。前記平板片７ｃの断面形状は一例として図３にあるような略ハの字型を有し、調整枠７ａの開口部７ｂ側の先端に取り付けられている。本例に示す略ハの字型形状は好適な一例であって、これに限定されることはない。軟質の弾性部材からなるスペーサーＳが前記調整枠７ａの裏面側に設けられている。前記調整孔Ｈがこのスペーサーにも設けられていると調整ネジを螺着する際施工性に優れる。このように、調整枠７ａと、平板片７ｃと、スペーサーＳとが押し出し成形等の方法で一体的に形成されていることが望ましい。バラバラの部材であると、中縦枠５の戸板対向木口面５ａに取り付ける際、大変な手間がかかり、施工作業性に劣るものとなる。 Further, a flat plate piece 7c made of a soft member is attached to the opening 7b side of the adjustment frame 7a. The cross-sectional shape of the flat plate piece 7c has, for example, a substantially square shape as shown in FIG. 3, and is attached to the tip of the adjustment frame 7a on the opening 7b side. The substantially square shape shown in this example is a preferred example and is not limited to this. A spacer S made of a soft elastic member is provided on the back side of the adjustment frame 7a. When the adjustment hole H is also provided in this spacer, the workability is excellent when the adjustment screw is screwed. Thus, it is desirable that the adjustment frame 7a, the flat plate piece 7c, and the spacer S are integrally formed by a method such as extrusion. When it is a disjoint member, it takes a great deal of labor when it is attached to the doorboard facing face 5a of the middle vertical frame 5 and the construction workability is inferior.

前記平板片７ｃとスペーサーＳの材質は軟質の弾性部材である。例えば、軟質のウレタン樹脂発泡体、軟質のポリエチレン樹脂発泡体、軟質のシリコン樹脂、軟質のナイロン樹脂等が好適である。軟質であること、弾性体としての特性を有すること、耐摩耗性に優れていること等が大切である。これらの条件を満たす部材であれば上記以外の材質の部材であっても勿論よいものとする。 The material of the flat plate piece 7c and the spacer S is a soft elastic member. For example, a soft urethane resin foam, a soft polyethylene resin foam, a soft silicon resin, a soft nylon resin, and the like are suitable. It is important to be soft, to have properties as an elastic body, and to be excellent in wear resistance. Of course, a member other than those described above may be used as long as it satisfies these conditions.

このようにして形成された隙間調整手段７を中縦枠５の戸板対向木口面５ａに調整ネジＮをねじ込んで取り付ける。この作業は戸板６を一旦取り外してから行うとよい。次に、戸板６を元へ戻し開閉操作を行い、開閉具合を確かめる。戸板６の表面と隙間調整手段７の平板片７ｃとの接触具合及び明かり漏れ防止機能の働き具合を確認する。もし、不具合があれば、その箇所の調整ネジＮのねじ込み程度を加減し、隙間調整手段７の突出量Ｔの寸法を戸板６の開閉操作と明かり漏れ防止機能の兼ね合いで調整する。このとき、前記調整ネジＮの締め具合を調整して調整する。このようにして戸板開閉具合と明かり漏れ防止機能にとって丁度よいバランスになっていることを確認する。 The gap adjusting means 7 formed in this way is attached by screwing an adjusting screw N to the door plate facing face 5a of the middle vertical frame 5. This operation may be performed after removing the door plate 6 once. Next, the door plate 6 is returned to the original position and an opening / closing operation is performed to check the opening / closing state. The contact condition between the surface of the door plate 6 and the flat piece 7c of the gap adjusting means 7 and the working condition of the light leakage prevention function are confirmed. If there is a problem, the degree of screwing of the adjusting screw N at that location is adjusted, and the dimension of the protruding amount T of the gap adjusting means 7 is adjusted by combining the opening / closing operation of the door plate 6 and the light leakage prevention function. At this time, the adjusting screw N is adjusted and adjusted. In this way, it is confirmed that the balance is just right for the door plate opening / closing state and the light leakage prevention function.

中縦枠５の戸板対向木口面５ａと戸板６の表面との隙間Ｃが戸板６の高さ方向で一律の寸法でなく、戸板６の反り具合によって隙間Ｃが戸板６の高さ方向で大小変化することが多々生じる。前記調整ネジＮが中縦枠５の戸板対向木口面５ａの高さ方向において１個でなく複数個設けられている。これらの調整ネジＮのねじ込み深さを慎重に調整することで、戸板開閉操作がスムーズで、且つ、明かり漏れが生じない引き戸構造体が可能となる。また、長期間引き戸を使用するうちに、前記隙間Ｃの大きさは変化していくが、前記調整ネジＮを利用すれば、この隙間Ｃの変化にも柔軟に対応可能となる。 The clearance C between the door plate facing face 5a of the middle vertical frame 5 and the surface of the door plate 6 is not uniform in the height direction of the door plate 6, but the clearance C is larger or smaller in the height direction of the door plate 6 due to the warpage of the door plate 6. There are many things that change. A plurality of the adjusting screws N are provided instead of one in the height direction of the door plate facing head surface 5 a of the middle vertical frame 5. By carefully adjusting the screwing depths of these adjusting screws N, a sliding door structure that allows smooth opening and closing operation of the door plate and does not cause light leakage is possible. Further, while the sliding door is used for a long time, the size of the gap C changes. However, if the adjusting screw N is used, the change of the gap C can be flexibly dealt with.

次に、本発明の調整手段７の隙間調整機能をさらに具体的に説明する。隙間調整手段７の調整枠７ａの裏面側弾性部材の付勢力により調整枠７ａの開口部７ｂ側に設けられている平板片７ｃが前記中縦枠５の戸板対向木口面５ａから戸板６の表面の方へ所定距離だけ突出して設けられている。 Next, the gap adjusting function of the adjusting means 7 of the present invention will be described more specifically. The flat plate piece 7c provided on the opening 7b side of the adjustment frame 7a by the urging force of the back surface side elastic member of the adjustment frame 7a of the gap adjustment means 7 extends from the door plate facing top surface 5a of the middle vertical frame 5 to the surface of the door plate 6. It protrudes by a predetermined distance toward.

前記調整ネジＮを強くねじ込むと、図３の（ロ）に示すように、調整枠７ａ裏面に設けられたスペーサーＳが圧縮変形し、平板片７ｃ先端と中縦枠５の戸板対向木口面５ａとの間の寸法、すなわち、隙間調整手段７の突出量Ｔが小さくなり、隙間Ｃが大きくなる。図３の（ロ）は前記突出量Ｔが最小の状態を示す。また、逆に調整ネジＮをゆるめる方向に調整すれば、図３の（イ）に示すように、前記突出量Ｔが大きくなり、隙間Ｃが小さくなる方向に調整される。図３の（イ）は前記突出量Ｔが最大の状態を示す。このとき、突出量Ｔの調整範囲はＬで図示された寸法範囲となる。このようにして、戸板６の反り具合によって、前記隙間Ｃが戸板６の高さ方向において種々変化することに対して、有効に対応可能となる。すなわち、隙間Ｃが大きい箇所では調整ネジＮをゆるめ、逆に隙間Ｃが小さい箇所では調整ネジＮを強く閉める方向に調整するとよい。 When the adjusting screw N is screwed in strongly, the spacer S provided on the back surface of the adjusting frame 7a is compressed and deformed as shown in FIG. , That is, the protrusion amount T of the gap adjusting means 7 is reduced, and the gap C is increased. FIG. 3B shows a state in which the protruding amount T is minimum. On the other hand, if the adjustment screw N is adjusted in the direction of loosening, the protrusion amount T is increased and the gap C is adjusted to be reduced as shown in FIG. FIG. 3A shows a state in which the protrusion amount T is the maximum. At this time, the adjustment range of the protrusion amount T is a dimension range shown by L. In this way, it is possible to effectively cope with various changes in the gap C in the height direction of the door plate 6 depending on the warpage of the door plate 6. That is, the adjustment screw N may be loosened at a location where the gap C is large, and conversely, the adjustment screw N may be tightly closed at a location where the gap C is small.

このように、本発明の隙間調整手段７は、構造自体が複雑でなく、引き戸をリフォームする際やメンテナンス時に、古い中縦枠５に施工現場で簡単に後付けが可能である。従って、引き戸構造体１を一旦解体し取り付けし直す必要がない。また、引き戸構造体１の隙間調整手段７を取り付けた後も外観意匠性に優れたものとなる。しかも、隙間調整作業性と安定性にも優れ、リフォームやメンテナンスの際、隙間調整手段７の平板片７ｃが多少古くなった場合でも隙間調整手段７を前後ひっくり返して、裏面側のスペーサーＳを平板片７ｃの代わりに用いることができる。すなわち、古くなった隙間調整手段７の裏面側も有効に使用でき両面使い可能であるので長期間使用可能でコストメリットもある。また、上記の如くリフォームやメンテナンス時に、引き戸構造体を一旦解体し取り付けし直す必要がないので手間や費用がかからず安価に取り付けできる。 Thus, the gap adjusting means 7 of the present invention is not complicated in structure, and can be easily retrofitted to the old middle vertical frame 5 at the construction site when renovating the sliding door or during maintenance. Therefore, there is no need to disassemble and reattach the sliding door structure 1 once. Further, even after the gap adjusting means 7 of the sliding door structure 1 is attached, the appearance design is excellent. In addition, the gap adjustment workability and stability are excellent, and even when the flat plate piece 7c of the gap adjustment means 7 is a little old at the time of renovation or maintenance, the gap adjustment means 7 is turned upside down so that the spacer S on the back side is removed. It can be used instead of the flat plate piece 7c. That is, the back side of the gap adjusting means 7 that has become obsolete can be used effectively and can be used on both sides, so that it can be used for a long time and has a cost advantage. Moreover, since it is not necessary to dismantle and reattach the sliding door structure during renovation and maintenance as described above, it is possible to install it at low cost without labor and cost.

図４において、本発明の第二実施形態における隙間調整手段７の詳細を説明する。本発明の第二実施形態における隙間調整手段７は、断面視略ロの字型を有する調整枠と、該調整枠７ａの正面側と裏面側に形成されている一対の軟質の弾性部材と、隙間調整手段７を中縦枠５の戸板対向木口面５ａに取り付けるとともに、隙間調整手段７の戸板対向木口面５ａからの突出量Ｔを適当な寸法に調整する働きを持つ調整ネジＮとで構成されている。 In FIG. 4, the detail of the clearance gap adjustment means 7 in 2nd embodiment of this invention is demonstrated. The gap adjusting means 7 in the second embodiment of the present invention includes an adjustment frame having a substantially square shape in cross section, a pair of soft elastic members formed on the front side and the back side of the adjustment frame 7a, The clearance adjusting means 7 is attached to the door plate facing face 5a of the middle vertical frame 5 and is composed of an adjusting screw N having a function of adjusting the protruding amount T of the gap adjusting means 7 from the door facing face 5a to an appropriate dimension. Has been.

前記調整枠７ａは、その正面側とそれと対向する裏面側の両方に調整枠７ａの長手方向（高さ方向）に複数個の調整孔Ｈがそれぞれ高さ位置を合わせて設けられている。該調整孔Ｈに調整ネジＮが嵌入され、該調整ネジＮによって、隙間調整手段７を中縦枠５の戸板対向木口面５ａに取り付けるとともに、隙間調整手段７の戸板対向木口面５ａからの突出量Ｔを適当な寸法に調整することが可能となる。 The adjustment frame 7a is provided with a plurality of adjustment holes H in the longitudinal direction (height direction) of the adjustment frame 7a on both the front side and the back side opposite to the adjustment frame 7a. An adjusting screw N is inserted into the adjusting hole H, and the adjusting screw N attaches the gap adjusting means 7 to the door plate facing face 5a of the middle vertical frame 5, and the gap adjusting means 7 protrudes from the door facing face 5a. The amount T can be adjusted to an appropriate dimension.

また、前記調整枠７ａに形成されている一対の軟質の弾性部材は、隙間調整手段７の正面及びそれと対向する裏面に略同様の形態のものが設けられている。本例では、隙間隠し機能を持つ平板片７ｃが隙間調整手段７の正面及びそれと対向する裏面の両方に形成されている。この平板片７ｃは隙間隠し機能の他に弾性部材としての機能を有している。このようにして、隙間調整手段７が、その正面側と裏面側の両方に略前後対称に形成されている。そして、前記中縦枠５の戸板対向木口面５ａに前記隙間調整手段７が調整枠７ａの裏面側の弾性部材を中縦枠５の戸板対向木口面５ａの側にし、調整枠７ａの正面側の弾性部材を戸板６の方から見て正面側にして、調整孔Ｈの箇所で前記調整ネジＮを中縦枠５の戸板対向木口面５ａにねじ込んで螺着し取り付け固定されている。 The pair of soft elastic members formed on the adjustment frame 7a are provided in substantially the same form on the front surface of the gap adjusting means 7 and the back surface facing it. In this example, the flat plate piece 7c having a gap concealing function is formed on both the front surface of the gap adjusting means 7 and the back surface facing it. The flat plate piece 7c has a function as an elastic member in addition to a gap concealing function. In this way, the gap adjusting means 7 is formed substantially symmetrically on both the front side and the back side. And the said clearance gap adjustment means 7 makes the elastic member of the back surface side of the adjustment frame 7a the door plate facing wooden front surface 5a side of the middle vertical frame 5, and the front side of the adjustment frame 7a on the door board facing wooden front surface 5a of the said middle vertical frame 5 The adjustment member N is screwed into and screwed into the door plate facing side surface 5a of the middle vertical frame 5 at the position of the adjustment hole H, with the elastic member of FIG.

このようにして、隙間調整手段７の調整枠７ａの裏面側弾性部材の付勢力により調整枠７ａの開口部７ｂ側に設けられている平板片７ｃが前記中縦枠５の戸板対向木口面５ａから戸板６の表面の方へ所定距離だけ突出して設けられている。 In this way, the flat plate piece 7c provided on the opening 7b side of the adjustment frame 7a by the urging force of the back side elastic member of the adjustment frame 7a of the gap adjusting means 7 is the door plate facing wooden front surface 5a of the middle vertical frame 5. From the door plate 6 toward the surface of the door plate 6 by a predetermined distance.

前記調整ネジＮを強くねじ込むと、図４の（ロ）に示すように、調整枠７ａの裏面側に設けられた弾性部材（第二実施形態においては、平板片７ｃである）が圧縮変形し、平板片７ｃ先端と中縦枠５の戸板対向木口面５ａとの間の寸法、すなわち、隙間調整手段７の突出量Ｔが小さくなり、隙間Ｃが大きくなる。図４の（ロ）は前記突出量Ｔが最小の状態を示す。また、逆に調整ネジＮをゆるめる方向に調整すれば、図４の（イ）に示すように、前記突出量Ｔが大きくなり、隙間Ｃが小さくなる方向に調整される。図４の（イ）は前記突出量Ｔが最大の状態を示す。このとき、突出量Ｔの調整範囲はＬで図示された寸法範囲となる。このようにして、戸板６の反り具合によって、前記隙間Ｃが戸板６の高さ方向において種々変化することに対して、有効に対応可能となる。すなわち、隙間Ｃが大きい箇所では調整ネジＮをゆるめ、逆に隙間Ｃが小さい箇所では調整ネジＮを強く閉める方向に調整するとよい。 When the adjustment screw N is screwed in strongly, the elastic member (in the second embodiment, the flat plate piece 7c) is compressed and deformed as shown in FIG. The dimension between the front end of the flat plate piece 7c and the door-plate facing face 5a of the middle vertical frame 5, that is, the protruding amount T of the gap adjusting means 7 is reduced, and the gap C is increased. FIG. 4B shows a state in which the protruding amount T is minimum. On the other hand, if the adjustment screw N is adjusted in the direction of loosening, the protrusion amount T is increased and the gap C is adjusted to be reduced as shown in FIG. FIG. 4A shows a state in which the protrusion amount T is the maximum. At this time, the adjustment range of the protrusion amount T is a dimension range shown by L. In this way, it is possible to effectively cope with various changes in the gap C in the height direction of the door plate 6 depending on the warpage of the door plate 6. That is, the adjustment screw N may be loosened at a location where the gap C is large, and conversely, the adjustment screw N may be tightly closed at a location where the gap C is small.

隙間調整手段７は幅が中縦枠５の厚み寸法よりも多少小さめの寸法を有し、中縦枠５の木口面に高さ方向のほぼ全長にわたって取り付けられており、見かけ上、細長い形状をした部材である。前記調整枠７ａは、例えば、硬質又は半硬質の塩ビ樹脂、オレフィン樹脂、アクリル樹脂、ポリエステル樹脂、ポリエチレン樹脂等の成型体である。例えば、押し出し成形等で製造される。調整枠７ａの形状は上記したように、断面視略ロの字型形状を有し、長手方向（高さ方向）に、調整ネジＮが嵌入されるための複数個の調整孔Ｈが表面側と裏面側の両方に略対称に設けられている。すなわち、前記調整孔Ｈは調整枠７ａの正面側と裏面側の両方に高さ位置を合わせた状態で設けられている。 The gap adjusting means 7 has a width that is slightly smaller than the thickness of the middle vertical frame 5, and is attached to the bottom surface of the middle vertical frame 5 over almost the entire length in the height direction. It is a member. The adjustment frame 7a is, for example, a molded body such as a hard or semi-rigid PVC resin, an olefin resin, an acrylic resin, a polyester resin, or a polyethylene resin. For example, it is manufactured by extrusion molding or the like. As described above, the shape of the adjustment frame 7a has a substantially square shape in cross-sectional view, and a plurality of adjustment holes H for inserting the adjustment screws N are provided on the surface side in the longitudinal direction (height direction). And are provided substantially symmetrically on both the back side and the back side. That is, the adjustment hole H is provided in a state where the height position is matched to both the front side and the back side of the adjustment frame 7a.

また、前記調整枠７ａの正面側に設けられている弾性部材は、軟質部材からなる平板片７ｃである。また、前記平板片７ｃの断面形状は一例として図４にあるような略ハの字型を有し、調整枠７ａの正面側の先端に取り付けられている。本例に示す略ハの字型形状は好適な一例であって、これに限定されることはない。また、調整枠７ａの裏面側にも正面側と略同様の形態の軟質の弾性部材が設けられており、平板片７ｃが形成されている。このように、調整枠７ａと、該調整枠７ａの正面側及び裏面側両方の平板片７ｃとが押し出し成形等の方法で一体的に形成されていることが望ましい。バラバラの部材であると、中縦枠５の戸板対向木口面５ａに取り付ける際、大変な手間がかかり、施工作業性に劣るものとなる。 The elastic member provided on the front side of the adjustment frame 7a is a flat plate piece 7c made of a soft member. Moreover, the cross-sectional shape of the flat plate piece 7c has a substantially square shape as shown in FIG. 4 as an example, and is attached to the front end of the adjustment frame 7a. The substantially square shape shown in this example is a preferred example and is not limited to this. Further, a soft elastic member having substantially the same form as the front side is provided on the back side of the adjustment frame 7a, and a flat plate piece 7c is formed. Thus, it is desirable that the adjustment frame 7a and the flat plate pieces 7c on both the front side and the back side of the adjustment frame 7a are integrally formed by a method such as extrusion molding. When it is a disjoint member, it takes a great deal of labor when it is attached to the doorboard facing face 5a of the middle vertical frame 5 and the construction workability is inferior.

前記平板片７ｃの材質は軟質の弾性部材である。例えば、軟質のウレタン樹脂発泡体、軟質のポリエチレン樹脂発泡体、軟質のシリコン樹脂、軟質のナイロン樹脂等が好適である。軟質であること、弾性体としての特性を有すること、耐摩耗性に優れていること等が大切である。これらの条件を満たす部材であれば上記以外の材質の部材であっても勿論よいものとする。 The material of the flat piece 7c is a soft elastic member. For example, a soft urethane resin foam, a soft polyethylene resin foam, a soft silicon resin, a soft nylon resin, and the like are suitable. It is important to be soft, to have properties as an elastic body, and to be excellent in wear resistance. Of course, a member other than those described above may be used as long as it satisfies these conditions.

このようにして形成された隙間調整手段７を中縦枠５の戸板対向木口面５ａに調整ネジＮをねじ込んで取り付ける。この作業は戸板６を一旦取り外してから行うとよい。次に、戸板６を元へ戻し開閉操作を行い、開閉具合を確かめる。戸板６の表面と隙間調整手段７の表面側の平板片７ｃとの接触具合及び明かり漏れ防止機能の働き具合を確認する。もし、不具合が有れば、その箇所の調整ネジＮのねじ込み程度を加減して、隙間調整手段７の前記突出量Ｔを調整する。このようにして、戸板開閉具合と明かり漏れ防止具合がバランスよく行われていることを確認する。 The gap adjusting means 7 formed in this way is attached by screwing an adjusting screw N to the door plate facing face 5a of the middle vertical frame 5. This operation may be performed after removing the door plate 6 once. Next, the door plate 6 is returned to the original position and an opening / closing operation is performed to check the opening / closing state. The contact condition between the surface of the door plate 6 and the flat plate piece 7c on the surface side of the gap adjusting means 7 and the working condition of the light leakage prevention function are confirmed. If there is a malfunction, the protruding amount T of the gap adjusting means 7 is adjusted by adjusting the screwing degree of the adjusting screw N at that point. In this way, it is confirmed that the door plate opening / closing state and the light leakage prevention state are performed in a well-balanced manner.

中縦枠５の戸板対向木口面５ａと戸板６の表面との隙間Ｃが戸板６の高さ方向で一律の寸法でなく、戸板６の反り具合によって隙間Ｃが戸板６の高さ方向で大小変化していることが多々生じる。前記調整ネジＮが中縦枠５の戸板対向木口面５ａの高さ方向において１個でなく複数個設けられている。これらの調整ネジＮのねじ込み深さを慎重に調整することで、戸板開閉がスムーズで、且つ、明かり漏れが生じない引き戸構造体が可能となる。また、長期間引き戸を使用するうちに、前記隙間Ｃの大きさは変化していくが、前記調整ネジＮを利用すれば、この隙間Ｃの変化にも柔軟に対応可能となる。 The clearance C between the door plate facing face 5a of the middle vertical frame 5 and the surface of the door plate 6 is not uniform in the height direction of the door plate 6, but the clearance C is larger or smaller in the height direction of the door plate 6 due to the warpage of the door plate 6. Many things are changing. A plurality of the adjusting screws N are provided instead of one in the height direction of the door plate facing head surface 5 a of the middle vertical frame 5. By carefully adjusting the screwing depths of these adjusting screws N, a sliding door structure that can smoothly open and close the door plate and does not cause light leakage is possible. Further, while the sliding door is used for a long time, the size of the gap C changes. However, if the adjusting screw N is used, the change of the gap C can be flexibly dealt with.

次に、本発明の調整手段７の隙間調整機能について説明する。調整ネジＮを強くねじ込むと、図４の（ロ）に示すように、調整枠７ａの裏面に設けられた弾性部材としての平板片７ｃが圧縮変形し、調整枠７ａの正面に設けられた平板片７ｃの先端と中縦枠５の戸板対向木口面５ａとの間の寸法、すなわち、隙間調整手段７の突出量Ｔが小さくなる方向に調整され、隙間Ｃが大きくなる。図４の（ロ）は前記突出量Ｔが最小の状態を示す。 Next, the gap adjusting function of the adjusting means 7 of the present invention will be described. When the adjustment screw N is strongly screwed in, as shown in FIG. 4B, the flat plate piece 7c as an elastic member provided on the back surface of the adjustment frame 7a is compressed and deformed, and the flat plate provided on the front surface of the adjustment frame 7a. The dimension between the tip of the piece 7c and the door-plate facing face 5a of the middle vertical frame 5, that is, the protrusion amount T of the gap adjusting means 7 is adjusted to be reduced, and the gap C is increased. FIG. 4B shows a state in which the protruding amount T is minimum.

また、逆に調整ネジＮをゆるめる方向に調整すれば、図４の（イ）に示すように、前記突出量Ｔが大きくなる方向に調整され、隙間Ｃが小さくなる。図４の（イ）は前記突出量Ｔが最大の状態を示す。このようにして、戸板６の反り具合によって、前記隙間Ｃが戸板６の高さ方向において種々変化することに対して、有効に対応可能となる。すなわち、隙間Ｃが大きい箇所では調整ネジＮをゆるめ、逆に隙間Ｃが小さい箇所では調整ネジＮを強く閉める方向に調整するとよい。 On the other hand, if the adjustment screw N is adjusted in the direction of loosening, as shown in FIG. 4A, the protrusion amount T is adjusted in the increasing direction, and the gap C is reduced. FIG. 4A shows a state in which the protrusion amount T is the maximum. In this way, it is possible to effectively cope with various changes in the gap C in the height direction of the door plate 6 depending on the warpage of the door plate 6. That is, the adjustment screw N may be loosened at a location where the gap C is large, and conversely, the adjustment screw N may be tightly closed at a location where the gap C is small.

また、本発明の第二実施形態における隙間調整手段７は、調整枠７ａに一対の軟質の弾性部材が形成されており、隙間調整手段７の正面及びそれと対向する裏面に略同様の形態の弾性部材が設けられている。このようにして、隙間調整手段７が、その正面側と裏面側の略前後対称になるようにして形成されている。そして、前記中縦枠５の戸板対向木口面５ａに前記隙間調整手段７が調整枠７ａの裏面側の弾性部材を中縦枠５の戸板対向木口面５ａの側にし、調整枠７ａの正面側の弾性部材を戸板６の方から見て正面側にして、前記調整孔Ｈの箇所で前記調整ネジＮを中縦枠５の戸板対向木口面５ａにねじ込んで螺着し取り付け固定されている。 Further, in the gap adjusting means 7 in the second embodiment of the present invention, a pair of soft elastic members are formed on the adjustment frame 7a, and the elasticity of substantially the same form on the front surface of the gap adjusting means 7 and the back surface facing it. A member is provided. In this way, the gap adjusting means 7 is formed so as to be approximately front-rear symmetrical on the front side and the back side. And the said clearance gap adjustment means 7 makes the elastic member of the back surface side of the adjustment frame 7a the door plate facing wooden front surface 5a side of the middle vertical frame 5, and the front side of the adjustment frame 7a on the door board facing wooden front surface 5a of the said middle vertical frame 5 The adjustment member N is screwed into and screwed into the door plate facing head surface 5a of the middle vertical frame 5 at the position of the adjustment hole H, and is fixedly attached.

このようにして、隙間調整手段７の調整枠７ａの裏面側弾性部材の付勢力により調整枠７ａの開口部側に設けられている平板片７ｃが前記中縦枠５の戸板対向木口面５ａから戸板６の表面の方へ所定距離だけ突出して設けられている。さらに、前記調整枠７ａの正面側の弾性部材は隙間隠し機能を有する平板片７ｃであり、調整枠裏面側の弾性部材についても隙間隠し機能を有する平板片７ｃである。このように、第二実施形態では、調整枠７ａの正面側及び裏面側に略同様の形態の平板片７ｃが設けられている。 In this way, the flat plate piece 7c provided on the opening side of the adjustment frame 7a by the urging force of the back side elastic member of the adjustment frame 7a of the gap adjustment means 7 is from the door plate facing wooden mouth surface 5a of the middle vertical frame 5. A predetermined distance protrudes toward the surface of the door plate 6. Further, the elastic member on the front side of the adjustment frame 7a is a flat plate piece 7c having a gap concealing function, and the elastic member on the back side of the adjustment frame is also a flat piece 7c having a gap concealing function. Thus, in 2nd embodiment, the flat piece 7c of the substantially the same form is provided in the front side and back surface side of the adjustment frame 7a.

このような構成を有する第二実施形態における隙間調整部材７は、その構造自体が複雑でなく、引き戸をリフォームする際やメンテナンス時に、古い中縦枠に施工現場で簡単に後付け可能で、しかも、古くなった隙間調整部材の裏面側も有効に使用できるものであり、リフォームやメンテナンス時に引き戸構造体を一旦解体し取り付けし直す必要がなく、そのための手間や費用がかからない。 The gap adjusting member 7 in the second embodiment having such a configuration is not complicated in its structure itself, and can be easily retrofitted to the old middle vertical frame at the construction site when renovating the sliding door or during maintenance, The back side of the gap adjusting member that has become old can also be used effectively, and it is not necessary to disassemble and reattach the sliding door structure at the time of renovation or maintenance.

すなわち、引き戸構造体１を施工後、長期間使用し、戸板６を繰り返し開閉すると、平板片７ｃの先端部が摩耗し明かり漏れが生じる恐れがある。この明かり漏れ現象は、夜間の暗い部屋においては、平板片７ｃが若干でも摩耗すると目立ち易くなる。しかし、この時点では平板片７ｃの弾性部材としての付勢力には全く問題がない。従って、長期間使用するうちに、平板片７ｃが若干摩耗して、明かり漏れ現象が生じた場合は、前記調整ネジＮをゆるめ、調整手段７そのものを中縦枠５の戸板対向木口面５ａから一旦取り外し、表裏面をひっくり返して平板片７ｃの摩耗していない裏面側を正面側にもってきて、逆に、若干摩耗した正面側を裏面側にして取り付けし直すと、また、新品同様の明かり漏れ機能を果たすことが可能となる。従って、表裏両面使いにとってよりいっそう好適であり、表裏両面使いが可能なことによって、長期耐久性にとって、よりいっそう優れたものとなる。 That is, if the sliding door structure 1 is used for a long time after the construction and the door plate 6 is opened and closed repeatedly, the tip of the flat plate piece 7c may be worn and light leakage may occur. This light leakage phenomenon becomes conspicuous in a dark room at night when the flat plate piece 7c is worn even slightly. However, at this time, there is no problem with the urging force of the flat plate piece 7c as an elastic member. Accordingly, when the flat plate piece 7c is slightly worn out during a long period of use and a light leakage phenomenon occurs, the adjustment screw N is loosened, and the adjustment means 7 itself is moved away from the door plate facing face 5a of the middle vertical frame 5. Once removed, the front and back sides are turned upside down, and the back side of the flat plate piece 7c is brought to the front side. It becomes possible to fulfill the light leakage function. Therefore, it is more suitable for both front and back side use, and the front and back side use is possible, so that the long-term durability is further improved.

図５において、本発明の第三実施形態における隙間調整手段７の詳細を説明する。本発明の第三実施形態における隙間調整手段７は、前記第一実施形態又は第二実施形態における隙間調整手段７を、前記中縦枠５の戸板対向木口面５ａ表面に直接取り付けるのではなく、前記中縦枠５の戸板対向木口面５ａに、中縦枠５の高さ方向に沿って、所定深さの凹部Ｕが形成され、前記凹部Ｕの中に隙間調整手段７を内蔵する構成である。すなわち、第一実施形態では調整枠７ａの裏面側のスペーサーＳ、又は、第二実施形態では裏面側の平板片７ｃを前記凹部Ｕの底側にして設ける構成である。 In FIG. 5, the detail of the clearance adjustment means 7 in 3rd embodiment of this invention is demonstrated. The gap adjusting means 7 in the third embodiment of the present invention does not directly attach the gap adjusting means 7 in the first embodiment or the second embodiment to the surface of the middle vertical frame 5 on the door plate facing side face 5a. A concave portion U having a predetermined depth is formed in the middle vertical frame 5 along the height direction of the middle vertical frame 5 on the door-plate-facing front end face 5a of the middle vertical frame 5, and the gap adjusting means 7 is built in the concave portion U. is there. In other words, in the first embodiment, the spacer S on the back surface side of the adjustment frame 7a or the flat plate piece 7c on the back surface side in the second embodiment is provided on the bottom side of the recess U.

前記中縦枠５の戸板対向木口面５ａ表面と調整枠７ａの正面端縁は標準位置として、略面一になるようにして調整ネジＮで取り付け固定されている。このとき、表面側の平板片７ｃが戸板対向木口面５ａ表面から若干量突出する構成とされている。この標準位置から調整ネジＮの締め具合を調整し、調整手段７の前記突出量Ｔを大きくしたり、又、小さくする。図５の（ロ）は前記突出量Ｔが最小の状態を示す。また、図５の（イ）は前記突出量Ｔが最大の状態を示す。 The front vertical edge of the middle vertical frame 5 and the front edge of the adjustment frame 7a are attached and fixed with an adjustment screw N so as to be substantially flush with each other as a standard position. At this time, it is set as the structure which the flat piece 7c of the surface side protrudes a little from the surface of the door-plate opposing front end surface 5a. By adjusting the tightening degree of the adjusting screw N from this standard position, the protruding amount T of the adjusting means 7 is increased or decreased. FIG. 5B shows a state in which the protruding amount T is minimum. FIG. 5A shows a state in which the protrusion amount T is maximum.

前記凹部Ｕの底部にある弾性部材の圧縮反発力と調整ネジＮの固定力とのバランスを調整し、前記木口面５ａ表面と調整枠７ａの正面端縁を略面一となるようにし、これを標準位置とし、これ以上に調整ネジＮを強く閉めると、図５の（ロ）に示すように、調整枠７ａが凹部Ｕ内にもぐりこみ、先端の平板片７ｃが引っ込み、戸板対向木口面５ａ表面から若干量突出するようになり、逆に、調整ネジＮをゆるめると、図５の（イ）に示すように、調整枠７ａが凹部Ｕから外へ突出するようになり、先端の平板片７ｃが戸板６の方へ大きく突出するようになる。上記のことは、第一実施形態の隙間調整手段だけでなく、もちろん、第二実施形態の隙間調整手段においても同様である。また、第三実施形態における隙間調整手段７においても、第一、第二実施形態における隙間調整手段７と同様に、先端の平板片７ｃの摩耗に対応するために、表裏ひっくり返して表面側の平板片７ｃを溝の凹部Ｕ内に納めると、新品同様に機能することは勿論である。 The balance between the compression repulsion force of the elastic member at the bottom of the recess U and the fixing force of the adjusting screw N is adjusted so that the front end edge of the top surface 5a and the adjustment frame 7a are substantially flush with each other. When the adjustment screw N is closed more strongly than this, as shown in FIG. 5 (b), the adjustment frame 7a is pulled into the recess U, the flat plate piece 7c at the front end is retracted, and the door plate facing face 5a. When the adjustment screw N is loosened, the adjustment frame 7a protrudes outward from the recess U as shown in FIG. 5 (a). 7c protrudes greatly toward the door plate 6. The above applies not only to the gap adjusting means of the first embodiment, but also to the gap adjusting means of the second embodiment. Also, in the gap adjusting means 7 in the third embodiment, like the gap adjusting means 7 in the first and second embodiments, in order to cope with the wear of the flat plate piece 7c at the tip, the front and back are turned upside down. Of course, when the flat plate piece 7c is housed in the recess U of the groove, it functions like a new product.
