It is suspended from the upper rail 6 so as to be slidable. As shown in FIG. 4, the first door panel 10A is provided so as to extend in the panel width direction at the lower end of the second door panel 10B, which constitutes an adjacent door panel adjacent in the door thickness direction (panel thickness). A guide body 37 having a guide portion 37a to be inserted into the guide groove 34 of the downward opening is provided. This guide body 37 has an attached portion 39 attached to the lower end portion of the first end portion in the panel width direction of the first door panel 10A. As shown in FIG. 10(b), the first door panel 10A includes a guide mounting member 36 provided to be accommodated in the panel width direction first end of the hollow cylindrical lower frame 30. there is The guide mounting member 36 is provided with a mounting hole 36f into which the mounted portion 39 is inserted through an insertion hole 30f provided in the lower frame 30. As shown in FIG. With such a configuration, the mounting portion 39 of the guide body 37 can be stably mounted by inserting it into the mounting hole 36f of the guide mounting member 36 housed in the hollow cylindrical lower frame 30. . Further, it is not necessary to attach the attached portion 39 of the guide body 37 to the vertical frame 14, and the size of the vertical frame 14 along the panel width direction can be reduced. An example of specific configurations of the guide mounting member 36 and the guide body 37 will be described later.
　引戸装置１は、図１及び図２に示すように、上レール６と、この上レール６にパネル幅方向にスライド自在に吊下支持される少なくとも一枚の可動パネルと、開放（全開）位置とされた上記可動パネルが納められる袖壁を構成する固定パネル１０Ｃと、を備えている。可動パネルのパネル本体１０と固定パネル１０Ｃのパネル本体１０とは、互いに同様の構成とされている。このような構成とすれば、可動パネルのパネル本体１０と固定パネル１０Ｃのパネル本体１０とを共通部品にすることができる。本実施形態に係る引戸装置１は、可動パネルを構成する第１戸パネル１０Ａと、この第１戸パネル１０Ａのパネル厚さ方向に隣接される可動パネルを構成する第２戸パネル１０Ｂと、を備えている。つまり、第１戸パネル１０Ａのパネル本体１０、第２戸パネル１０Ｂのパネル本体１０及び固定パネル１０Ｃのパネル本体１０は、互いに同様の構成とされている。 As shown in FIGS. 1 and 2, the sliding door device 1 includes an upper rail 6, at least one movable panel supported by the upper rail 6 so as to be slidable in the panel width direction, and an open (fully open) position. and a fixed panel 10C forming a sleeve wall in which the movable panel is housed. The panel body 10 of the movable panel and the panel body 10 of the fixed panel 10C have the same configuration. With such a configuration, the panel main body 10 of the movable panel and the panel main body 10 of the fixed panel 10C can be used as a common component. The sliding door device 1 according to this embodiment includes a first door panel 10A that constitutes a movable panel, and a second door panel 10B that constitutes a movable panel adjacent to the first door panel 10A in the panel thickness direction. I have. That is, the panel body 10 of the first door panel 10A, the panel body 10 of the second door panel 10B, and the panel body 10 of the fixed panel 10C have the same configuration.
　これら第１戸パネル１０Ａ、第２戸パネル１０Ｂ及び固定パネル１０Ｃは、建物内に設けられた開口部に設置される。固定パネル１０Ｃは、開口部の開口幅方向一方側端に固定的に設置される。第１戸パネル１０Ａは、この固定パネル１０Ｃのパネル厚さ方向一方側において、閉鎖位置（図２（ａ）参照）と開放位置（図２（ｂ）参照）との間をスライド自在とされている。第２戸パネル１０Ｂは、この第１戸パネル１０Ａのパネル厚さ方向一方側において、閉鎖位置（図２（ａ）参照）と開放位置（図２（ｂ）参照）との間をスライド自在とされている。これら第１戸パネル１０Ａ及び第２戸パネル１０Ｂを開放位置とすれば、これらの側方に出入口５が形成される。図例では、開放位置において、第１戸パネル１０Ａ及び第２戸パネル１０Ｂと固定パネル１０Ｃとがパネル厚さ方向に見て互いに完全に重なり合う位置とならずに、いわゆる引き残しが形成される例を示している。つまり、第１戸パネル１０Ａは、開放位置において、その戸先側（出入口５側）の端部が固定パネル１０Ｃの出入口５側端部よりも出入口５側となるように配される。第２戸パネル１０Ｂは、開放位置において、その戸先側の端部が第１戸パネル１０Ａの戸先側の端部よりも出入口５側となるように配される。この第２戸パネル１０Ｂの戸先側端部のパネル厚さ方向両側に、引手部材が取り付けられていてもよい。 These first door panel 10A, second door panel 10B and fixed panel 10C are installed in an opening provided in the building. The fixed panel 10C is fixedly installed at one side end of the opening in the width direction of the opening. The first door panel 10A is slidable between a closed position (see FIG. 2(a)) and an open position (see FIG. 2(b)) on one side of the fixed panel 10C in the panel thickness direction. there is The second door panel 10B is slidable between a closed position (see FIG. 2(a)) and an open position (see FIG. 2(b)) on one side of the first door panel 10A in the panel thickness direction. It is When the first door panel 10A and the second door panel 10B are in the open position, the doorway 5 is formed on the side of them. In the example shown in the figure, in the open position, the first door panel 10A, the second door panel 10B, and the fixed panel 10C do not completely overlap each other when viewed in the panel thickness direction, and a so-called leftover portion is formed. is shown. That is, in the open position, the first door panel 10A is arranged such that the door tip side (doorway 5 side) end is closer to the doorway 5 side than the doorway 5 side end of the fixed panel 10C. In the open position, the second door panel 10B is arranged such that the end on the door tip side is closer to the doorway 5 than the end on the door tip side of the first door panel 10A. A pull member may be attached to both sides in the panel thickness direction of the door tip side edge of the second door panel 10B.
　これら第１戸パネル１０Ａ及び第２戸パネル１０Ｂを閉鎖位置とすれば、出入口５が閉鎖される。閉鎖位置においては、第１戸パネル１０Ａの戸尻側の端部と固定パネル１０Ｃの出入口５側端部とがパネル厚さ方向に見て互いに重なり合い、召し合わせ部となる。また、閉鎖位置においては、第２戸パネル１０Ｂの戸尻側の端部と第１戸パネル１０Ａの戸先側の端部とがパネル厚さ方向に見て互いに重なり合い、召し合わせ部となる。図例では、閉鎖位置において、第１戸パネル１０Ａと固定パネル１０Ｃとの召し合わせ部における縦フレーム１４，１４同士がパネル厚さ方向に見て互いに重なり合うように配置されている。また、閉鎖位置において、第２戸パネル１０Ｂと第１戸パネル１０Ａとの召し合わせ部における縦フレーム１４，１４同士がパネル厚さ方向に見て互いに重なり合うように配置されている。 When the first door panel 10A and the second door panel 10B are in the closed position, the doorway 5 is closed. In the closed position, the end portion of the first door panel 10A on the side of the door bottom and the end portion of the fixed panel 10C on the side of the doorway 5 overlap with each other when viewed in the panel thickness direction to form a meeting portion. In the closed position, the edge of the second door panel 10B on the door bottom side and the edge of the first door panel 10A on the door tip side overlap with each other when viewed in the panel thickness direction to form a meeting portion. In the illustrated example, when the first door panel 10A and the fixed panel 10C meet in the closing position, the vertical frames 14, 14 overlap each other when viewed in the panel thickness direction. Also, in the closed position, the vertical frames 14, 14 at the meeting portion of the second door panel 10B and the first door panel 10A are arranged so as to overlap each other when viewed in the panel thickness direction.
　図例では、これら第１戸パネル１０Ａ、第２戸パネル１０Ｂ及び固定パネル１０Ｃが設置される開口部は、壁体を貫通するように設けられている。この開口部は、図２及び図４に示すように、上側が天井２によって区画され、下側が床３によって区画され、開口幅方向両側が壁体の開口側端面４，４によって区画されている。図例では、壁体の壁厚方向両面及び開口側端面４，４は、石膏ボード等の壁下地ボードに貼着された壁クロス（壁紙）によって構成された例を示している。つまり、開口部の開口幅方向両側において戸枠等の縦枠部材を露出させていない例を示している。
　図例では、壁体の開口側端面４，４と床３との入隅部に設けられる巾木の厚さよりも開口幅方向に沿う寸法が大とされた隙間調整突部４ａ，４ａを開口幅方向両側に設けた例を示している。隙間調整突部４ａ，４ａは、各開口側端面４，４に対向するように配される固定パネル１０Ｃ及び第２戸パネル１０Ｂが巾木に当接して隙間が形成されるようなことがないように、固定パネル１０Ｃ及び第２戸パネル１０Ｂと開口側端面４，４との間の隙間を塞ぐ。これら隙間調整突部４ａ，４ａは、床３から天井２までの開口高全体に亘って上下方向に延びるように設けられている。 In the illustrated example, the openings in which the first door panel 10A, the second door panel 10B and the fixed panel 10C are installed are provided so as to pass through the wall. As shown in FIGS. 2 and 4, the opening is defined by the ceiling 2 on the upper side, by the floor 3 on the lower side, and by the end faces 4, 4 of the wall on both sides in the width direction of the opening. . In the illustrated example, both sides of the wall in the wall thickness direction and the end faces 4, 4 on the opening side are constituted by wall cloth (wallpaper) adhered to a wall base board such as a gypsum board. In other words, it shows an example in which vertical frame members such as door frames are not exposed on both sides of the opening in the width direction of the opening.
In the illustrated example, clearance adjusting protrusions 4a, 4a are provided with a dimension along the width direction of the opening larger than the thickness of the baseboard provided at the corner between the opening side end faces 4, 4 of the wall and the floor 3. An example provided on both sides in the width direction is shown. The gap adjusting projections 4a, 4a prevent the fixing panel 10C and the second door panel 10B, which are arranged to face the opening-side end faces 4, 4, from coming into contact with the baseboard and forming a gap. , the gaps between the fixed panel 10C and the second door panel 10B and the opening side end faces 4, 4 are closed. These clearance adjusting protrusions 4a, 4a are provided so as to extend vertically over the entire opening height from the floor 3 to the ceiling 2. As shown in FIG.
　これら隙間調整突部４ａ，４ａのパネル厚さ方向に沿う寸法（見込寸法）は、パネル本体１０の厚さ寸法（四周フレーム１３の見込寸法）よりも小とされている。図例では、これら隙間調整突部４ａ，４ａを構成する隙間調整部材の見込方向両側に壁下地ボードの端面が突き合わせられた例を示している。つまり、見込方向両側の壁下地ボード間に一部が埋込状に設けられた隙間調整部材の壁下地ボードからの突出部が隙間調整突部４ａ，４ａとされている。開口幅方向一方側の隙間調整突部４ａは、固定パネル１０Ｃのパネル幅方向一方側の端面に対向する位置となるように設けられている。開口幅方向他方側の隙間調整突部４ａは、第２戸パネル１０Ｂの戸先側の端面に対向する位置となるように設けられている。つまり、開口幅方向一方側の隙間調整突部４ａと開口幅方向他方側の隙間調整突部４ａとは、見込方向にずれた位置となるように設けられている。
　この隙間調整突部４ａ，４ａの表面となる見付面及び見込面には、壁クロス（壁紙）が貼着されていない例を示している。つまり、開口側端面４，４を構成する壁クロスは、隙間調整突部４ａ，４ａの見込方向両側に突き合わせられるように、隙間調整突部４ａ，４ａの見込方向両側の壁下地ボードに貼着された例を示している。これら隙間調整突部４ａ，４ａを構成する隙間調整部材は、例えば、ＭＤＦ等の木質系材料から形成された芯材の表面に、化粧シートの貼着や塗装等の適宜の表面化粧処理が施された構成とされていてもよい。
　第１戸パネル１０Ａ、第２戸パネル１０Ｂ及び固定パネル１０Ｃが設置される開口部としては、上記のような構成に限られず、開口部の開口幅方向両側が縦枠部材によって区画されていてもよい。また、開口部の上側が上枠によって区画されていてもよく、開口部の下側が下枠によって区画されていてもよい。 The dimension (estimated dimension) along the panel thickness direction of these gap adjusting protrusions 4a, 4a is smaller than the thickness dimension of the panel main body 10 (estimated dimension of the four-peripheral frame 13). The figure shows an example in which the end faces of the wall base board are abutted on both sides of the gap adjusting members constituting the gap adjusting projections 4a, 4a in the viewing direction. In other words, the gap adjusting protrusions 4a, 4a are protrusions from the wall base boards of the gap adjusting members partially embedded between the wall base boards on both sides in the viewing direction. The gap adjusting protrusion 4a on one side in the opening width direction is provided so as to face the end face on one side in the panel width direction of the fixed panel 10C. The gap adjusting protrusion 4a on the other side in the opening width direction is provided so as to face the end face of the second door panel 10B on the door tip side. That is, the gap adjusting protrusion 4a on one side in the opening width direction and the gap adjusting protrusion 4a on the other side in the opening width direction are provided so as to be shifted in the viewing direction.
An example in which the wall cloth (wallpaper) is not adhered to the viewing surface and the viewing surface, which are the surfaces of the clearance adjusting protrusions 4a, 4a, is shown. That is, the wall cloth forming the opening side end faces 4, 4 is adhered to the wall substrate boards on both sides of the gap adjusting protrusions 4a, 4a in the viewing direction so as to butt against both sides of the gap adjusting protrusions 4a, 4a in the viewing direction. example. The gap adjusting members forming the gap adjusting protrusions 4a, 4a are formed of, for example, a woody material such as MDF, and the surface of the core material is subjected to an appropriate surface cosmetic treatment such as attaching a decorative sheet or painting. It may be configured as
The opening in which the first door panel 10A, the second door panel 10B, and the fixed panel 10C are installed is not limited to the configuration described above. good. Moreover, the upper side of the opening may be defined by the upper frame, and the lower side of the opening may be defined by the lower frame.
　これら第１戸パネル１０Ａ、第２戸パネル１０Ｂ及び固定パネル１０Ｃのパネル本体１０，１０，１０は、上記したようにいずれも同様の構成であるので、以下では、具体的構成の一例について、一つのパネル本体１０を例にとって説明する。
　パネル本体１０は、図１、図２及び図４に示すように、板状部材１１と、この板状部材１１の四周を囲むように設けられた四周フレーム１３と、を備えている。
　パネル本体１０は、上下（戸高）方向に長尺な略矩形平板状とされている。このパネル本体１０の戸高寸法（長さ寸法）は、出入口５の開口高に応じた寸法でもよい。図例では、パネル本体１０の長さ寸法は、床３から天井２までの開口高とされた出入口５に応じた寸法とされている。このパネル本体１０の長さ寸法は、例えば、２４００ｍｍ～３０００ｍｍ程度であってもよい。パネル本体１０の幅寸法は、出入口５を開閉する戸パネル（第１戸パネル１０Ａ及び第２戸パネル１０Ｂ）の枚数や固定パネル１０Ｃの有無、これらが設置される開口部の開口幅に応じて適宜の寸法としてもよく、例えば、６００ｍｍ～１２００ｍｍ程度でもよい。 Since the panel bodies 10, 10, 10 of the first door panel 10A, the second door panel 10B, and the fixed panel 10C all have the same configuration as described above, an example of a specific configuration will be described below. An example of the panel main body 10 will be described.
As shown in FIGS. 1, 2 and 4, the panel body 10 includes a plate-like member 11 and four-peripheral frames 13 provided to surround the plate-like member 11 on all four sides.
The panel body 10 has a substantially rectangular flat plate shape elongated in the vertical (door height) direction. The door height dimension (length dimension) of the panel body 10 may be a dimension corresponding to the opening height of the doorway 5 . In the illustrated example, the length dimension of the panel body 10 is a dimension corresponding to the doorway 5 having an opening height from the floor 3 to the ceiling 2 . The length dimension of this panel body 10 may be, for example, about 2400 mm to 3000 mm. The width dimension of the panel body 10 depends on the number of door panels (first door panel 10A and second door panel 10B) that open and close the entrance 5, the presence or absence of the fixed panel 10C, and the opening width of the opening where these are installed. Any size may be used, for example, about 600 mm to 1200 mm.
　板状部材１１は、パネル本体１０と同様、上下方向に長尺な略矩形平板状とされている。この板状部材１１は、アクリルやポリカーボネート等の合成樹脂系材料やガラス等の透光性材料から形成され、透光性を有した透光板とされている。つまり、この板状部材１１は、採光部を構成する。この板状部材１１は、例えば、２枚のガラス板を厚さ方向に接合した合わせガラスでもよい。この板状部材１１は、略無色透明に限られず、有色透明や半透明でもよい。この板状部材１１としては、例えば、透明材料に着色剤が添加されて有色透明とされていてもよく、樹脂フィルム等が積層されて有色透明とされていてもよい。この板状部材１１としては、スモークガラス状やすりガラス状とされていてもよく、また、２枚の透明（透光）パネル間に、和紙等のシート材を介在させた構成とされていてもよい。板状部材１１としては、ハーフミラー状とされていてもよく、さらには、厚さ方向両側が鏡とされていてもよく、その他の不透光な板体でもよく、また、厚さ方向両面が略平坦面状とされた構成に限られず、凹凸が設けられていてもよい。 The plate-like member 11 has a substantially rectangular flat plate shape elongated in the vertical direction, similar to the panel body 10 . The plate member 11 is made of a synthetic resin material such as acryl or polycarbonate or a translucent material such as glass, and is a translucent plate having translucency. In other words, the plate-like member 11 constitutes a lighting section. The plate-shaped member 11 may be, for example, laminated glass in which two glass plates are joined together in the thickness direction. The plate-like member 11 is not limited to being substantially colorless and transparent, and may be colored and transparent or translucent. The plate-shaped member 11 may be colored and transparent, for example, by adding a coloring agent to a transparent material, or may be colored and transparent by laminating a resin film or the like. The plate-like member 11 may be in the form of smoked glass or frosted glass, or may have a structure in which a sheet material such as Japanese paper is interposed between two transparent (translucent) panels. good. The plate-like member 11 may have a half-mirror shape, may have mirrors on both sides in the thickness direction, may be other opaque plates, or may have both sides in the thickness direction. is not limited to the configuration in which the surface is substantially flat, and unevenness may be provided.
　この板状部材１１は、図２及び図４に示すように、その四周の端部１１ａが四周フレーム１３に設けられた受入溝１４ａ，１４ａ，２０ａ，３０ａに差し込まれて四周フレーム１３に保持されている。板状部材１１の四周の各端部１１ａは、その端部１１ａが嵌め込まれたガスケット（グレイジングガスケット）１２を介して受入溝１４ａ，１４ａ，２０ａ，３０ａに保持されている。このようなガスケット１２としては、断面略Ｃ字状とされたいわゆるグレイジングチャンネルやパネル厚さ方向に分離されたグレイジングビードでもよい。板状部材１１の端部１１ａを四周フレーム１３に保持させる態様としては、このような態様に限られず、その他、種々の態様の採用が可能である。 As shown in FIGS. 2 and 4, the plate-like member 11 is held by the four peripheral frame 13 by inserting its four peripheral ends 11a into receiving grooves 14a, 14a, 20a, and 30a provided in the four peripheral frame 13. ing. Four peripheral ends 11a of the plate member 11 are held in receiving grooves 14a, 14a, 20a, 30a via gaskets (glazing gaskets) 12 in which the ends 11a are fitted. Such a gasket 12 may be a so-called glazing channel having a substantially C-shaped cross section or a glazing bead separated in the thickness direction of the panel. The manner in which the end portion 11a of the plate-like member 11 is held by the four-circumference frame 13 is not limited to this manner, and various other manners can be employed.
　四周フレーム１３は、図１、図２及び図４に示すように、パネル本体１０のパネル幅方向両端部を構成する一対の縦フレーム１４，１４と、パネル本体１０の上端部を構成する上フレーム２０と、パネル本体１０の下端部を構成する下フレーム３０と、を備えている。
　両側の縦フレーム１４，１４は、上下方向に長尺状とされている。これら縦フレーム１４，１４には、互いに向き合う方向に向けて開口するように、かつそれぞれの全長に亘って延びるように受入溝１４ａ，１４ａが設けられている。これら両側の縦フレーム１４，１４は、互いに同様の構成であるので、以下では、一方を例にとって説明する。 As shown in FIGS. 1, 2 and 4, the four peripheral frames 13 include a pair of vertical frames 14, 14 forming both ends of the panel body 10 in the panel width direction, and an upper frame forming the upper end of the panel body 10. 20 and a lower frame 30 forming the lower end of the panel body 10 .
The vertical frames 14, 14 on both sides are elongated in the vertical direction. Receiving grooves 14a, 14a are provided in these vertical frames 14, 14 so as to open in directions facing each other and extend over the entire length of each. Since the vertical frames 14, 14 on both sides have the same configuration, one of them will be described below as an example.
　縦フレーム１４は、パネル厚さ方向に沿う寸法よりもパネル幅方向に沿う寸法が小とされている。縦フレーム１４のパネル厚さ方向に沿う寸法は、板状部材１１の厚さ寸法よりも大とされている。この縦フレーム１４のパネル厚さ方向に沿う寸法は、一般的な戸パネルの厚さと概ね同様な寸法であってもよく、例えば、３０ｍｍ～４０ｍｍ程度でもよい。縦フレーム１４のパネル幅方向に沿う寸法は、例えば、１０ｍｍ～３０ｍｍ程度でもよい。図例では、縦フレーム１４のパネル幅方向に沿う寸法は、縦フレーム１４のパネル厚さ方向に沿う寸法の約１／３程度とされている。
　縦フレーム１４のパネル幅方向内側（パネル本体１０の幅方向中央側）に向く内側面１４ｂ，１４ｂは、図２及び図５（ｃ）に示すように、パネル厚さ方向両外側から板状部材１１に向かうに従いパネル幅方向中央側となるように傾斜する傾斜面状とされている。このような構成とすれば、縦フレーム１４自体のパネル幅方向に沿う寸法を確保しながらも、縦フレーム１４のパネル厚さ方向外側に向く表面（見付面）のパネル幅方向に沿う寸法を小さくすることができ、すっきりとした印象を与えることができる。 The vertical frame 14 has a dimension along the panel width direction smaller than a dimension along the panel thickness direction. The dimension along the panel thickness direction of the vertical frame 14 is larger than the thickness dimension of the plate member 11 . The dimension along the panel thickness direction of the vertical frame 14 may be approximately the same dimension as the thickness of a general door panel, for example, about 30 mm to 40 mm. The dimension of the vertical frame 14 along the panel width direction may be, for example, about 10 mm to 30 mm. In the illustrated example, the dimension of the vertical frame 14 along the panel width direction is about 1/3 of the dimension of the vertical frame 14 along the panel thickness direction.
As shown in FIGS. 2 and 5(c), the inner side surfaces 14b, 14b of the vertical frame 14 facing inward in the panel width direction (the central side in the width direction of the panel body 10) are plate-shaped members from both outer sides in the panel thickness direction. 11, the surface is inclined toward the center in the width direction of the panel. With such a configuration, while ensuring the dimension of the vertical frame 14 itself along the panel width direction, the dimension along the panel width direction of the surface of the vertical frame 14 facing outward in the panel thickness direction (viewing surface) is reduced. It can be made small and can give a clean impression.
　この縦フレーム１４のパネル厚さ方向両側の内側面１４ｂ，１４ｂは、パネル厚さ方向両外側縁部からパネル厚さ方向中心側となる板状部材１１に向かうに従いパネル幅方向中央側となるように傾斜面状とされている。これらパネル厚さ方向両側の内側面１４ｂ，１４ｂは、横断面視において、パネル厚さ方向中心線を対称軸として線対称状とされている。
　これら内側面１４ｂ，１４ｂは、横断面視において、略円弧状とされた凹湾曲面状とされている。これら内側面１４ｂ，１４ｂの縦フレーム１４のパネル厚さ方向外側に向く表面とのなす角度や曲率半径等は、見栄え上の観点等から適宜の角度や曲率半径とされていてもよい。図例では、これら内側面１４ｂ，１４ｂのパネル厚さ方向中心側端部に、板状部材１１の表面に対して略垂直面状とされた部位を設けた例を示している。
　図例では、これら内側面１４ｂ，１４ｂをパネル厚さ方向に見た状態のパネル幅方向に沿う寸法は、縦フレーム１４のパネル厚さ方向外側に向く表面のパネル幅方向に沿う寸法と略同寸法とされている。つまり、縦フレーム１４のパネル厚さ方向外側に向く表面のパネル幅方向に沿う寸法は、縦フレーム１４自体のパネル幅方向に沿う寸法の約１／２の寸法とされている。 The inner side surfaces 14b, 14b on both sides in the panel thickness direction of the vertical frame 14 are arranged so as to become the center side in the panel width direction from the both outer edges in the panel thickness direction toward the plate member 11, which is the center side in the panel thickness direction. It is assumed to be a sloped surface. These inner side surfaces 14b, 14b on both sides in the thickness direction of the panel are symmetrical with respect to the center line in the thickness direction of the panel in a cross-sectional view.
These inner side surfaces 14b, 14b are generally arc-shaped concave curved surfaces in cross-sectional view. The angles and radii of curvature formed between the inner side surfaces 14b, 14b and the surface of the vertical frame 14 facing outward in the panel thickness direction may be set appropriately from the viewpoint of appearance. The drawing shows an example in which a portion that is substantially perpendicular to the surface of the plate-like member 11 is provided at the end portion of the inner side surfaces 14b, 14b on the central side in the panel thickness direction.
In the illustrated example, the dimension along the panel width direction when these inner side surfaces 14b, 14b are viewed in the panel thickness direction is substantially the same as the dimension along the panel width direction of the surface of the vertical frame 14 facing outward in the panel thickness direction. dimensioned. In other words, the dimension along the panel width direction of the surface of the vertical frame 14 facing outward in the panel thickness direction is about half the dimension along the panel width direction of the vertical frame 14 itself.
　この縦フレーム１４のパネル幅方向外側面には、パネル本体１０のパネル幅方向一方側の当接対象に当接されるクッション１７（図２及び図３参照）を保持する保持溝１４ｃがパネル幅方向外側に向けて開口し、かつ全長に亘って延びるように設けられている。図例では、縦フレーム１４のパネル厚さ方向中央側部位においてパネル厚さ方向に間隔を空けて２本の保持溝１４ｃ，１４ｃが設けられた例を示している。これら保持溝１４ｃ，１４ｃのそれぞれに保持されるクッション１７，１７は、縦フレーム１４のパネル幅方向外側面からパネル幅方向外側に向けて突出するように、かつ全長に亘って延びるように設けられている。これらクッション１７，１７のパネル厚さ方向に沿う寸法やパネル幅方向に沿う突出寸法は、当接対象との隙間を防止する観点や衝撃を吸収する観点等から適宜の寸法としてもよく、例えば、２ｍｍ～５ｍｍ程度でもよい。図例では、固定パネル１０Ｃのパネル幅方向一方側の端面に、これに対向する開口幅方向一方側の隙間調整突部４ａに当接されるクッション１７，１７を設けた例を示している。第２戸パネル１０Ｂの戸先側の端面に、これに対向する開口幅方向他方側の隙間調整突部４ａに当接されるクッション１７，１７を設けた例を示している。図例では、これら固定パネル１０Ｃのパネル幅方向一方側の端面及び第２戸パネル１０Ｂの戸先側の端面以外の端面の保持溝１４ｃには、クッション１７を設けていない例を示しているが、このような例に限られない。 A holding groove 14c for holding a cushion 17 (see FIGS. 2 and 3) that abuts on one side of the panel body 10 in the panel width direction is formed on the outer side surface of the vertical frame 14 in the panel width direction. It is provided so as to open toward the direction outside and extend over the entire length. The drawing shows an example in which two holding grooves 14c, 14c are provided at intervals in the panel thickness direction at the central portion of the vertical frame 14 in the panel thickness direction. The cushions 17, 17 held in the holding grooves 14c, 14c, respectively, are provided so as to protrude outward in the panel width direction from the panel width direction outer surface of the vertical frame 14 and extend over the entire length. ing. The dimension along the panel thickness direction and the projection dimension along the panel width direction of the cushions 17, 17 may be set appropriately from the viewpoint of preventing gaps between the cushions 17 and 17 and absorbing shocks. It may be about 2 mm to 5 mm. The figure shows an example in which cushions 17, 17 are provided on one end surface of the fixed panel 10C in the panel width direction, the cushions 17, 17 coming into contact with the gap adjusting projection 4a on the one side in the opening width direction facing the fixed panel 10C. An example is shown in which cushions 17, 17 are provided on the end surface of the door tip side of the second door panel 10B to abut against the gap adjusting protrusion 4a on the other side in the opening width direction facing the second door panel 10B. In the illustrated example, an example is shown in which the cushion 17 is not provided in the holding groove 14c of the end face other than the end face of the fixing panel 10C on one side in the panel width direction and the end face of the second door panel 10B on the door tip side. , but not limited to such examples.
　上フレーム２０は、図１に示すように、パネル幅方向に長尺状とされている。この上フレーム２０には、図４に示すように、下方側に向けて開口するように、かつ全長に亘って延びるように受入溝２０ａが設けられている。この上フレーム２０は、図５（ｂ）及び図６（ｃ）に示すように、パネル厚さ方向に沿う寸法よりも上下方向に沿う寸法が小とされている。この上フレーム２０のパネル厚さ方向に沿う寸法は、板状部材１１の厚さ寸法よりも大とされている。この上フレーム２０のパネル厚さ方向に沿う寸法は、上記した縦フレーム１４のパネル厚さ方向に沿う寸法と概ね同寸法でもよい。図例では、上フレーム２０のパネル厚さ方向に沿う寸法は、縦フレーム１４のパネル厚さ方向に沿う寸法よりも僅かに小さい寸法とされている。この上フレーム２０の上下方向に沿う寸法は、縦フレーム１４のパネル幅方向に沿う寸法よりも大とされている。図例では、上フレーム２０の上下方向に沿う寸法は、上フレーム２０のパネル厚さ方向に沿う寸法の約３／５程度とされている。 The upper frame 20 is elongated in the panel width direction, as shown in FIG. As shown in FIG. 4, the upper frame 20 is provided with a receiving groove 20a that opens downward and extends over the entire length. As shown in FIGS. 5(b) and 6(c), the upper frame 20 has a vertical dimension smaller than a panel thickness dimension. The dimension of the upper frame 20 along the panel thickness direction is larger than the thickness dimension of the plate member 11 . The dimension of the upper frame 20 along the panel thickness direction may be substantially the same as the dimension of the vertical frame 14 along the panel thickness direction. In the illustrated example, the dimension of the upper frame 20 along the panel thickness direction is slightly smaller than the dimension of the vertical frame 14 along the panel thickness direction. The dimension of the upper frame 20 along the vertical direction is larger than the dimension of the vertical frame 14 along the panel width direction. In the illustrated example, the dimension of the upper frame 20 along the vertical direction is about 3/5 of the dimension of the upper frame 20 along the panel thickness direction.
　上フレーム２０の下方側に向く下側面２０ｂ，２０ｂは、図５（ｂ）及び図６（ｃ）に示すように、パネル厚さ方向両外側から板状部材１１に向かうに従いパネル高さ方向中央側となるように傾斜する傾斜面状とされている。これら下側面２０ｂ，２０ｂは、縦フレーム１４の内側面１４ｂ，１４ｂと同様、縦断面視において、パネル厚さ方向中心線を対称軸として線対称状とされ、かつ略円弧状とされた凹湾曲面状とされている。縦断面視における下側面２０ｂ，２０ｂと、横断面視における縦フレーム１４の内側面１４ｂ，１４ｂとは、略同寸同形状とされている。
　上フレーム２０のパネル厚さ方向両外側に向く面は、下端部を除いて縦フレーム１４のパネル厚さ方向両外側に向く表面と略平行状の垂直面状とされている。上フレーム２０のパネル厚さ方向両外側に向く面の下端部は、下方側に向かうに従いパネル厚さ方向外側となるように傾斜する傾斜面状とされている。この上フレーム２０のパネル厚さ方向両外側に向く面の下端部と下側面２０ｂとによってパネル厚さ方向両外側に向けて突出する長手方向に見て尖頭状の突部が形成されている。 As shown in FIGS. 5(b) and 6(c), the lower side surfaces 20b, 20b of the upper frame 20, which face downward, extend toward the plate-like member 11 from both sides in the panel thickness direction and extend toward the center in the panel height direction. It is made into the shape of an inclined surface which inclines so that it may become the side. Similar to the inner surfaces 14b, 14b of the vertical frame 14, the lower surfaces 20b, 20b are linearly symmetrical about the center line in the thickness direction of the panel in a vertical cross-sectional view, and have a substantially arcuate concave curve. It is said to be planar. The lower side surfaces 20b, 20b in a vertical cross-sectional view and the inner side surfaces 14b, 14b of the vertical frame 14 in a horizontal cross-sectional view have substantially the same size and shape.

A longitudinal end surface of the upper frame 20 facing the outside in the panel width direction (vertical frame 14 side) is substantially perpendicular to the longitudinal direction of the upper frame 20 . The upper end of the vertical frame 14 is provided with a receiving concave stepped portion 15 for receiving the longitudinal end of the upper frame 20 . With such a configuration, even when the inner side surfaces 14b, 14b of the vertical frame 14 and the lower side surfaces 20b, 20b of the upper frame 20 are inclined as described above, they can be joined with good appearance. can. For example, it is conceivable to diagonally cut both the upper end of the vertical frame 14 and the longitudinal end of the upper frame 20 and mate them together in a mitered joint. Gaps tend to occur easily. On the other hand, according to the above configuration, as shown in FIGS. 6(a) and 6(b), the end of the upper frame 20 whose longitudinal end faces are formed in a substantially vertical plane shape is the recessed stepped portion 15 for receiving the vertical frame 14. Since it is received and joined to the joint, it becomes difficult for misalignment and gaps to be formed.

It is formed to be missing (excised). The receiving concave stepped portion 15 is formed so as to open toward the inner side and the upper side in the panel width direction. The stepped bottom face of the receiving recessed stepped portion 15 facing inward in the panel width direction is substantially vertical so that the longitudinal end faces of the upper frame 20 can abut against each other. The stepped wall surfaces 15a, 15a facing upward of the receiving recessed step portion 15 are arranged in the panel width direction (the longitudinal direction of the upper frame 20) so as to be able to butt against the inclined lower side surfaces 20b, 20b of the upper frame 20. direction) along the lower side surfaces 20b, 20b of the upper frame 20.
