Description

本発明は、壁体にあけた開口部を開閉する既存の開き戸に代えて、引戸を扉枠の外側に重ねてスライド自在に取り付けて付け替える扉付替システムに関する。   The present invention relates to a door replacement system that replaces an existing hinged door that opens and closes an opening formed in a wall body and slidably attaches and replaces a sliding door on the outside of a door frame.

最近、建物内を介護に適した構造にリフォームする場合には、既存の各種扉の中で、回動開閉式の開き戸は取り外し、要介護者に優しいスライド開閉式の引戸に付け替える改造を行うことが多い。従来、開き戸を引戸に付け替える場合は、既存の扉枠から開き戸を取り外してから、たとえば図９に示すように、引戸１を、所謂アウトセット方式により、同じ扉枠２の外側（図中手前側）に重ねて、開口部３と壁体４の戸袋壁４ａに沿って左右に往復移動可能に取り付ける。そのため、壁体４には、上壁４ｂに長尺なガイドレール５を横向けに取り付ける一方、このガイドレール５に、開口部３と対向する板面に軸支した一対の戸車６・６を係合させて、引戸１を図示全閉位置と全開位置間を左右にスライド自在に吊持している。   Recently, when remodeling the building into a structure suitable for nursing care, remove the pivoting opening / closing type door from the existing doors and replace it with a sliding opening / closing type sliding door that is kind to the care recipient. There are many. Conventionally, when replacing a hinged door with a sliding door, after removing the hinged door from the existing door frame, for example, as shown in FIG. 9, the sliding door 1 is placed outside the same door frame 2 by the so-called outset method (front side in the figure). And is attached so as to be able to reciprocate left and right along the door pocket wall 4a of the opening 3 and the wall 4. Therefore, a long guide rail 5 is attached to the wall 4 on the upper wall 4b sideways, and a pair of door wheels 6 and 6 pivotally supported on a plate surface facing the opening 3 are attached to the guide rail 5. The sliding door 1 is suspended between the fully closed position and the fully open position shown in FIG.

ところが、従来、既存の開き戸を囲む扉枠周縁の壁体４は、通常、扉枠２の真上の上壁４ｂ内を除き、間柱など補強材のない壁下地構造なので、引戸１の長いガイドレール５を横向けに壁付けするには取付強度に乏しく、そのため、この壁下地構造が原因で、開き戸を簡単に引戸１に付け替えられない場合が多いという課題があった。   However, conventionally, the wall body 4 on the periphery of the door frame surrounding the existing hinged door is usually a wall base structure without a reinforcing material such as a spacer except for the inside of the upper wall 4b directly above the door frame 2, so that the long guide of the sliding door 1 is used. In order to wall-mount the rail 5 sideways, the mounting strength is poor. Therefore, there is a problem that the swing door cannot be easily replaced with the sliding door 1 due to the wall base structure.

また、この扉枠周縁の壁体４が、仮にガイドレール５を取付可能に補強された壁下地構造である場合には、開き戸を引戸１に付け替えることが可能であっても、従来は、図９に示すように引戸１を閉めたときに、戸袋壁４ａからガイドレール５が正面に露出して見栄えが悪く、インテリア上、引戸周りの美観を低下させるという課題があった。   In addition, when the wall body 4 on the peripheral edge of the door frame is a wall base structure reinforced so that the guide rail 5 can be attached, even if the hinged door can be replaced with the sliding door 1, When the sliding door 1 is closed as shown in FIG. 9, the guide rail 5 is exposed from the door pocket wall 4a to the front, so that the appearance is poor, and there is a problem that the appearance around the sliding door is lowered on the interior.

そこで、上記した課題を解決すべく、請求項１に記載の発明は、たとえば以下に示す図示実施の形態のとおり、壁体Ｗの開口部Ｓを開閉する既存の開き戸に代え、引戸Ｄを扉枠Ｆの外側に重ねて、前記開口部Ｓと前記壁体Ｗの戸袋壁１２に沿ってスライド自在に取り付けて付け替える扉付替システムであって、前記扉枠Ｆの天井側に有する横枠材１３に沿わせて前記壁体Ｗの上壁面１０ａに取り付け、前記引戸Ｄの開閉ストロークに対応する長さで該引戸Ｄの幅より短い第１ガイドレール２０と、該第１ガイドレール２０の戸尻側の上側に前記上壁面１０ａで軸支して回転自在に取り付ける第１戸車２５と、前記開口部Ｓと対向する側の前記引戸Ｄの片側板面１６に横向けに取り付けて、前記第１戸車２５を係合させる、前記第１ガイドレール２０に合わせた長さの第２ガイドレール３０と、該第２ガイドレール３０の戸先側の下側に前記引戸Ｄの片側板面１６で軸支して回転自在に取り付け、前記第１ガイドレール２０に係合させる第２戸車３５と、前記戸袋壁１２の横でその幅方向に沿って床面Ｂ上に取り付け、前記第１ガイドレール２０に合わせた長さの第３ガイドレール５０と、前記引戸Ｄの下端縁１９の戸先側と戸尻側に取り付け、それぞれ前記第３ガイドレール５０に係合させる一対の第３戸車４０・４５とを備え、前記第１ガイドレール２０と前記第２戸車３５、前記第２ガイドレール３０と前記第１戸車２５、前記第３ガイドレール５０と一対の前記第３戸車４０・４５とが係合する４箇所の係合点のうち、常に少なくとも３点で係合して前記引戸Ｄを支える構造としてなることを特徴とする。   Therefore, in order to solve the above-described problem, the invention described in claim 1 is replaced with an existing hinged door that opens and closes the opening S of the wall body W, for example, as shown in the following illustrated embodiment. A door replacement system that overlaps the outside of the frame F and is slidably attached and replaced along the door pocket wall 12 of the opening S and the wall body W, and has a horizontal frame member on the ceiling side of the door frame F The first guide rail 20 is attached to the upper wall surface 10a of the wall body W along the opening 13 and has a length corresponding to the opening / closing stroke of the sliding door D and shorter than the width of the sliding door D, and the door of the first guide rail 20 The first door 25 is pivotally supported by the upper wall surface 10a on the upper side of the bottom side and is rotatably attached, and the first door 25 is attached to the one-side plate surface 16 of the sliding door D on the side facing the opening S. The first guide rail that engages one door pulley 25. A second guide rail 30 having a length matching that of the first guide rail 30, and a second guide rail 30 on the lower side of the door-end side of the second guide rail 30. A second door wheel 35 to be engaged with the rail 20; a third guide rail 50 attached to the floor surface B along the width direction of the door pocket wall 12 along the width direction; and a length corresponding to the first guide rail 20; And a pair of third door wheels 40 and 45 which are attached to the door end side and the door bottom side of the lower end edge 19 of the sliding door D and engage with the third guide rail 50, respectively. Of the four engagement points where the second door 35, the second guide rail 30 and the first door 25, the third guide rail 50 and the pair of third doors 40 and 45 are engaged, always at least 3 Structure that supports the sliding door D by engaging at a point Characterized in that by comprising.

請求項２に記載の発明は、請求項１に記載の扉付替システムにおいて、たとえば以下に示す図示実施の形態のとおり、前記第１および第２ガイドレール２０・３０は、前記扉枠Ｆが前記壁体Ｗの壁面から立ち上がる扉枠高さｈより薄型な構造のレール体で形成し、前記第１ガイドレール２０を前記上壁面１０ａに面付けする一方、前記第２ガイドレール３０を前記引戸Ｄの片側板面１６に面付けして両ガイドレール２０・３０が前記扉枠Ｆの高さｈ内に収まるように前記壁体Ｗに組み付けてなることを特徴とする。   According to a second aspect of the present invention, in the door replacement system according to the first aspect, for example, as in the illustrated embodiment shown below, the first and second guide rails 20 and 30 include the door frame F. A rail body having a structure thinner than a door frame height h rising from the wall surface of the wall body W is formed, the first guide rail 20 is faced to the upper wall surface 10a, and the second guide rail 30 is moved to the sliding door. The guide rails 20 and 30 are assembled to the wall body W so as to be within the height h of the door frame F by facing the one side plate surface 16 of D.

請求項１に記載の発明によれば、扉枠周縁の壁下地構造に影響されることなく、常に引戸のガイドレールを壁付けして開き戸を簡単に引戸に付け替えることができる。また、付け替えた引戸で開口部を閉める状態のとき、従来の如く戸袋壁からガイドレールが露出することがなく、それだけ引戸周りの見栄えを良好とし、インテリア上の美観を向上させることができる。しかも、付け替えた引戸は、全閉位置と全開位置間を往復移動動するとき、ガイドレールと戸車とが係合する４箇所の係合点のうち、常に少なくとも３点で係合して支え、常に安定してスライド移動して開口部を開閉することができる。   According to the first aspect of the present invention, the sliding door can be easily replaced with the sliding door by always attaching the guide rail of the sliding door to the wall without being influenced by the wall base structure around the door frame. Further, when the opening is closed with the replaced sliding door, the guide rail is not exposed from the door pocket wall as in the prior art, and the appearance around the sliding door can be improved accordingly, and the aesthetics of the interior can be improved. Moreover, when the reciprocating sliding door reciprocates between the fully closed position and the fully open position, the sliding door is always engaged and supported by at least three of the four engagement points where the guide rail and the door wheel engage. The opening can be opened and closed by sliding stably.

請求項２に記載の発明によれば、第１ガイドレールが扉枠から手前に出っ張ることなく扉枠高さ内に収まるように壁体に面付けされ、第２ガイドレールも第１ガイドレールと共に扉枠の扉枠高さ内に収まるように付設され、その結果、壁体に引戸を面付けするためにわざわざ上壁面に彫り込みを設けるなど、大工など専門家による取付工程が必要でなくなり、それだけ素人でも簡単に引戸に付け替えることを可能にすることができる。   According to the second aspect of the present invention, the first guide rail is faced to the wall body so as to be within the height of the door frame without protruding from the door frame, and the second guide rail together with the first guide rail. Attached so that it fits within the door frame height of the door frame. As a result, a carpenter or other specialist installation process is not required, such as engraving on the upper wall surface to impress the sliding door on the wall body. Even an amateur can easily change to a sliding door.

以下、図面を参照しつつ、本発明の実施の形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の扉付替システムを適用した引戸構造体を引戸全閉状態において示す正面図、図２は引戸構造体の壁体側の構造を示す分解斜視図、図３は引戸構造体の引戸側の構造を示す分解斜視図である。引戸構造体は、いずれも既存の壁体Ｗおよび扉枠Ｆと、付け替え用の引戸Ｄとを備える。   FIG. 1 is a front view showing a sliding door structure to which the door replacement system of the present invention is applied in a fully closed state, FIG. 2 is an exploded perspective view showing the structure of the sliding door structure on the wall side, and FIG. 3 is a sliding door structure. It is a disassembled perspective view which shows the structure of the sliding door side. Each of the sliding door structures includes an existing wall body W and door frame F, and a sliding door D for replacement.

引戸構造体において、壁体Ｗは、少なくとも開口部Ｓの真上の上壁１０が間柱のような縦補強材で補強された壁下地構造であるとする。図中符号１２は、開口部Ｓを全開したとき引戸Ｄが重なる戸袋壁に相当する壁部分である。扉枠Ｆは、始めに取り外す開き戸（図示省略）の既存の戸枠体で、天井側横枠材１３と一対の縦枠材１４・１５とで矩形に開口部Ｓを枠付けしている。そして、壁体Ｗの壁面から立ち上がる扉枠Ｆの高さｈは、図示例では略９ｍｍとする。一方、引戸Ｄは、大小開口面積の異なる一般の開口部に対し使用できるように、例えば高さ２１００ｍｍの比較的縦長なパネルからなり、開口部Ｓと対向する側の片側板面１６の戸先寄りに、戸当り１７を横向けに付設している。そして、扉枠Ｆの外側に重ねて、壁体Ｗに沿って所定の開閉ストロークの長さ図中左右にスライド自在に組み付けるアウトセット構造になっている。   In the sliding door structure, the wall body W is assumed to be a wall base structure in which at least the upper wall 10 directly above the opening S is reinforced with a vertical reinforcing material such as a stud. Reference numeral 12 in the figure denotes a wall portion corresponding to a door pocket wall on which the sliding door D overlaps when the opening S is fully opened. The door frame F is an existing door frame body of a hinged door (not shown) to be removed first, and the opening S is framed in a rectangular shape by the ceiling side horizontal frame member 13 and the pair of vertical frame members 14 and 15. The height h of the door frame F rising from the wall surface of the wall W is approximately 9 mm in the illustrated example. On the other hand, the sliding door D is made of a relatively long panel having a height of 2100 mm, for example, so that it can be used for general openings having different large and small opening areas, and the door tip of the one side plate surface 16 on the side facing the opening S. A door-to-door 17 is attached to the side. And it has an outset structure that is slidably assembled to the left and right in the figure of the length of a predetermined opening / closing stroke along the wall body W, overlapping the outside of the door frame F.

そこで、本発明の扉付替システムは、上記引戸構造体の壁体Ｗにおいて、上壁１０に取り付ける第１ガイドレール２０および第１戸車２５を備える一方、引戸Ｄにおいて、その片側板面１６に取り付ける第２ガイドレール３０および第２戸車３５と、同じ引戸Ｄの下端縁１９に取り付ける一対の第３戸車４０・４５を備える。他方、床面Ｂにおいて、戸袋壁１２の横に取り付ける第３ガイドレール５０を備える。   Therefore, the door replacement system of the present invention includes the first guide rail 20 and the first door wheel 25 attached to the upper wall 10 in the wall body W of the sliding door structure, while the sliding door D has the one side plate surface 16 thereof. The second guide rail 30 and the second door 35 to be attached, and a pair of third doors 40 and 45 attached to the lower edge 19 of the same sliding door D are provided. On the other hand, on the floor surface B, a third guide rail 50 attached to the side of the door pocket wall 12 is provided.

第１ガイドレール２０は、図２に示すように、金属板を曲げ加工したもので、平らな中央板部２０ａの両側端２０ｂ・２０ｂを各々略直角に曲げて立ち上げ、立ち上げた先端片を更に互いに向き合う側へ断面Ｌ形に屈曲させて、戸車係合部２０ｃ・２０ｃを形成してなる。両側端２０ｂ・２０ｂの立ち上げ高さは、上記扉枠Ｆの扉枠高さｈより小さく、全体に薄型に曲げ成形してなる。レール長は、引戸Ｄの開閉ストロークに対応する長さで、且つ引戸Ｄの幅よりは僅かに短い長さ寸法とする。そして、長さ方向両端には、それぞれ樹脂製のエンドブロック２１・２１を差し込んでレール体として組み立ててなる。第１戸車２５は、車輪の円周面中央に環状にガイド凹溝を有した滑車形で、取付用アングル２２の取付板部２２ａに枢軸１８で回転自在に取り付けてなる。   As shown in FIG. 2, the first guide rail 20 is formed by bending a metal plate. The first guide rail 20 is raised by bending both side ends 20b and 20b of the flat central plate portion 20a substantially at right angles, and then rising up. Are further bent in an L-shaped cross section toward the sides facing each other to form the door engaging portions 20c and 20c. The rising heights of the side ends 20b and 20b are smaller than the door frame height h of the door frame F, and are formed by being bent thinly as a whole. The rail length is a length corresponding to the opening / closing stroke of the sliding door D and is slightly shorter than the width of the sliding door D. Then, end blocks 21 and 21 made of resin are respectively inserted into both ends in the length direction and assembled as rail bodies. The first door wheel 25 is a pulley shape having a guide groove in an annular shape in the center of the circumferential surface of the wheel, and is rotatably attached to the attachment plate portion 22a of the attachment angle 22 by the pivot 18.

第２ガイドレール３０は、第１ガイドレール２０と同様に金属板を曲げ加工したもので、図３に示すように、平らな中央板部３０ａの両側端３０ｂ・３０ｂを各々略直角に曲げて立ち上げ、立ち上げた先端片を更に互いに向き合う側へ断面Ｌ形に屈曲させて、戸車係合部３０ｃ・３０ｃを形成してなる。また第１ガイドレール２０と同様、両側端３０ｂ・３０ｂの立ち上げ高さは、上記扉枠Ｆの扉枠高さｈより小さく、全体に薄型に曲げ成形し、レール長は、第１ガイドレール２０に合わせた長さ寸法で形成している。そして、両端に樹脂製エンドブロック２１を差し込んで組み立ててなる。第２戸車３５は、第１戸車２５と同様な形状の滑車形で、取付用アングル３２の取付板部３２ａに枢軸３３で軸支して回転自在に取り付けてなる。   The second guide rail 30 is formed by bending a metal plate in the same manner as the first guide rail 20, and as shown in FIG. 3, both side ends 30b and 30b of the flat central plate portion 30a are bent substantially at right angles. The door-end engaging portions 30c and 30c are formed by bending up and bending the raised end pieces into L-shaped cross sections toward the opposite sides. Further, like the first guide rail 20, the rising heights of both side ends 30b and 30b are smaller than the door frame height h of the door frame F, and are bent thinly as a whole, and the rail length is the first guide rail. It is formed with a length dimension adapted to 20. The resin end block 21 is inserted into both ends and assembled. The second door pulley 35 is a pulley shape having the same shape as that of the first door wheel 25, and is rotatably attached to the attachment plate portion 32a of the attachment angle 32 by a pivot 33.

第３戸車４０・４５は、第２戸車３５と反対に車輪の円周面に環状にガイド凸部を有したキャスタ形で、それぞれキャスタ用の取付ブラケット４１・４６に回転自在に取り付けている。そして、引戸Ｄの下端縁１９の戸先側と戸尻側の角部にあけた取付穴に、一部車輪が下端縁１９から下向きに露出した状態で、取付ブラケット４１・４６で軸支して回転自在に内設している。   The third door pulleys 40 and 45 are casters having annular guide projections on the circumferential surface of the wheel, opposite to the second door pulleys 35, and are rotatably attached to caster mounting brackets 41 and 46, respectively. Then, the mounting brackets 41 and 46 are pivotally supported in the mounting holes formed in the corners on the door end side and the door bottom side of the lower end edge 19 of the sliding door D with some wheels exposed downward from the lower end edge 19. And can be rotated freely.

一方、第３ガイドレール５０は、図２に示すように、帯状の金属板を曲げ加工したもので、平らな中央板部５０ａの幅方向中心を凹ませて長さ方向に車輪係合溝５０ｂを形成してなる。レール長は、第１および第２ガイドレール２０・３０に合わせて、引戸Ｄの開閉ストロークに対応する長さに形成している。   On the other hand, as shown in FIG. 2, the third guide rail 50 is formed by bending a band-shaped metal plate, and the center of the flat central plate portion 50a is recessed so that the wheel engagement groove 50b extends in the length direction. Formed. The rail length is formed to a length corresponding to the opening / closing stroke of the sliding door D according to the first and second guide rails 20 and 30.

そこで、以上の部品構成からなる本発明の扉付替システムにおいて、既設の開き戸を引戸Ｄに付け替える場合、扉枠Ｆから開き戸を取り外してから、壁体Ｗには、第１ガイドレール２０を、開口部Ｓの真上で、扉枠Ｆの横枠材１３に沿わせて上壁１０に取り付ける。そのとき、第１ガイドレール２０は、戸車係合部２０ｃ・２０ｃを正面に向けて、中央板部２０ａを上壁面１０ａに面付けし、その結果、扉枠Ｆから手前に出っ張ることなく扉枠高さｈ内に収まるように組み付けられる。次いで、同じ上壁面１０ａには、第１ガイドレール２０の戸尻側の上側に、取付用アングル２２を取付板部２２ａにて面付けし、第１戸車２５を板面に沿って立てた縦向けに取り付け、その結果、第１ガイドレール２０と共に扉枠Ｆの扉枠高さｈ内に収まるように付設される。   Therefore, in the door replacement system of the present invention composed of the above components, when replacing an existing hinged door with the sliding door D, the first guide rail 20 is attached to the wall W after the hinged door is removed from the door frame F. Attached to the upper wall 10 along the horizontal frame member 13 of the door frame F, just above the opening S. At that time, the first guide rail 20 faces the door pulley engaging portions 20c and 20c to the front, the center plate portion 20a faces the upper wall surface 10a, and as a result, the door frame does not protrude from the door frame F to the front. It is assembled to fit within the height h. Next, on the same upper wall surface 10a, a mounting angle 22 is attached to the upper side of the first guide rail 20 on the door bottom side by a mounting plate portion 22a, and the first door wheel 25 is erected along the plate surface. As a result, the first guide rail 20 and the first guide rail 20 are attached so as to be within the door frame height h.

一方、引戸Ｄには、図３に示すよう、片側板面１６の上端縁１６ａに幅方向に沿って第２ガイドレール３０を横向けに取り付ける。そのとき、第２ガイドレール２０は、戸車係合部２０ｃ・２０ｃを表側に向けて中央板部２０ａで片側板面１６に面付けする。また、引戸Ｄの片側板面１６には、第２ガイドレール３０の戸先側の下側に、取付用アングル３２を取付板部３２ａにおいて面付けし、第２戸車３５を板面に沿って立てた縦向けに取り付ける。   On the other hand, as shown in FIG. 3, the second guide rail 30 is attached to the sliding door D sideways along the width direction on the upper edge 16 a of the one-side plate surface 16. At that time, the second guide rail 20 faces the one-side plate surface 16 with the central plate portion 20a with the door engaging portions 20c and 20c facing the front side. In addition, on the one-side plate surface 16 of the sliding door D, an attachment angle 32 is applied to the lower side of the second guide rail 30 on the door tip side at the attachment plate portion 32a, and the second door wheel 35 is arranged along the plate surface. Install it vertically.

次いで、この引戸Ｄを持ち上げて、所謂アウトセット方式により、扉枠Ｆの外側（図１中手前側）に重ねて壁体Ｗに懸架する。そのとき、引戸Ｄは、図４に示すように、第２戸車３５を、壁体Ｗ側の第１ガイドレール２０の戸車係合部２０ｃ・２０ｃに係合する一方、図５に示すように、第２ガイドレール３０の戸車係合部３０ｃ・３０ｃに第１戸車３５を係合させると共に、第３戸車４０・４５を、床面Ｂ側の第３ガイドレール５０の車輪係合溝５０ｂに係合する。そして、引戸Ｄを、全閉位置（図１・図６参照）と全開位置（図７・図８参照）との間を開口部Ｓと戸袋壁１２に沿ってスライド往復可能に壁体Ｗに取り付けて付け替える。すると、引戸Ｄは、全閉位置と全開位置間を往復移動するとき、第１ガイドレール２０と第２戸車３５、第２ガイドレール３０と第１戸車２５、第３ガイドレール５０と一対の第３戸車４０・４５とが係合する合計４箇所の係合点のうち、常に少なくとも３点で係合して支えられる構造になっている。   Next, the sliding door D is lifted and suspended on the wall W in a so-called outset manner, overlapping the outside of the door frame F (the front side in FIG. 1). At that time, as shown in FIG. 4, the sliding door D engages the second door 35 with the door engaging portions 20c and 20c of the first guide rail 20 on the wall body W side, as shown in FIG. The first door 35 is engaged with the door engaging portions 30c and 30c of the second guide rail 30, and the third door 40 and 45 are inserted into the wheel engaging groove 50b of the third guide rail 50 on the floor surface B side. Engage. Then, the sliding door D is slidably reciprocated along the opening S and the door pocket wall 12 between the fully closed position (see FIGS. 1 and 6) and the fully open position (see FIGS. 7 and 8). Install and replace. Then, when the sliding door D reciprocates between the fully closed position and the fully opened position, the first guide rail 20 and the second door wheel 35, the second guide rail 30 and the first door wheel 25, and the third guide rail 50 and a pair of first guide rails. It has a structure in which it is always supported by engaging at least three points among the total four engagement points with which the three-door carts 40 and 45 are engaged.

従って、以上の扉付替システムを適用した引戸構造体では、引戸Ｄを押し引きし、それに応じて開口部Ｓを開閉すると、第１ガイドレール２０の戸車係合部２０ｃ・２０ｃに沿って第２戸車３５が転動する一方、第２ガイドレール３０の戸車係合部３０ｃ・３０ｃに沿って第１戸車２５が転動すると共に、第３ガイドレール５０の車輪係合溝５０ｂに沿って第３戸車４０又は第３戸車４５が転動しながら、引戸Ｄをスライドさせて往復移動させる。そして、引戸Ｄをスライドさせて開口部Ｓを閉じるとき、図１および図６に示すように、戸当り１７の戸先側ゴム１７ａが戸先側縦枠材１４に当たって引戸Ｄを停止し、開口部Ｓが全閉した全閉位置に位置決める。そして、このように引戸Ｄで開口部Ｓを閉める状態のとき、戸尻側の戸袋壁１２から第１ガイドレール２０が露出することがなく、それだけ引戸周りの見栄えを良くしている。一方、引戸Ｄをスライドさせて開口部Ｓを開くときは、図７および図８に示すように、戸当り１７は、戸尻側の戸当りゴム１７ｂが戸尻側縦枠材１５に当たって引戸Ｄを停止して開口部１０が全開した開位置に位置決める。   Therefore, in the sliding door structure to which the above door replacement system is applied, when the sliding door D is pushed and pulled and the opening S is opened / closed accordingly, the sliding door structure is changed along the door engaging portions 20c and 20c of the first guide rail 20. While the two-door wheel 35 rolls, the first door wheel 25 rolls along the door wheel engaging portions 30c and 30c of the second guide rail 30, and the second door wheel 35 moves along the wheel engaging groove 50b of the third guide rail 50. While the three-door cart 40 or the third door-cart 45 rolls, the sliding door D is slid to reciprocate.
