FIG.

以下、本発明の実施形態について図面を用いて詳細に説明する。
図１は、本発明に係る建具の一実施形態を示す正面図であり、建具を屋内側から見た状態を示している。この建具１は、上横枠２１と下横枠２２と左右一対の縦枠２３、２３とで矩形に形成された枠体２の内側に、４枚の障子３～６を備えている。図１は、これら４枚の障子３～６が全て閉じられた状態を示している。建具１は、このように４枚の障子３～６が閉じられることにより、屋内側と屋外側とを隔てるように構成される。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
Fig. 1 is a front view of one embodiment of a fitting according to the present invention, showing the fitting as seen from the indoor side. This fitting 1 is equipped with four shoji screens 3-6 inside a rectangular frame body 2 formed by an upper horizontal frame 21, a lower horizontal frame 22, and a pair of left and right vertical frames 23, 23. Fig. 1 shows the state in which these four shoji screens 3-6 are all closed. The fitting 1 is configured so that by closing the four shoji screens 3-6 in this way, the fitting 1 separates the indoor side from the outdoor side.

４枚の障子３～６のうち、中央に配置される２枚の障子４、５は、上横枠２１及び下横枠２２に形成された同一のレール（図示せず）上を左右にスライド移動するように枠体２に取り付けられている。また、両端に配置される２枚の障子３、６は、上横枠２１及び下横枠２２に、中央の障子４、５がスライド移動するレールの屋外側に平行に配置された同一のレール（図示せず）上を左右にスライド移動するように枠体２に取り付けられている。 Of the four shoji screens 3 to 6, the two central shoji screens 4 and 5 are attached to the frame 2 so that they can slide left and right on the same rails (not shown) formed on the upper horizontal frame 21 and lower horizontal frame 22. The two shoji screens 3 and 6 at both ends are attached to the frame 2 so that they can slide left and right on the same rails (not shown) that are parallel to the outdoor side of the rails on which the central shoji screens 4 and 5 slide.

この建具１は、両端の障子３、６がそれぞれ縦枠２３、２３に突き当てられると共に、これらの障子３、６の屋内側に配置される障子４、５が、建具１の中央部で突き合わされることにより閉じられる。閉じられた状態において、建具１の中央部に、障子４と障子５との突合せ部１０が構成される。この建具１において、中央に配置される２枚の障子４、５のうちの一方（図１における右側）の障子５が、本発明の第１の障子に対応し、他方（図１における左側）の障子４が、本発明の第２の障子に対応する。 This fitting 1 is closed by butting the shoji screens 3, 6 at both ends against the vertical frames 23, 23, respectively, and butting the shoji screens 4, 5 located on the indoor side of these shoji screens 3, 6 together in the center of the fitting 1. In the closed state, a butt joint 10 between the shoji screens 4 and 5 is formed in the center of the fitting 1. In this fitting 1, of the two shoji screens 4, 5 located in the center, the shoji screen 5 on the right side (in Fig. 1) corresponds to the first shoji screen of the present invention, and the other shoji screen 4 on the left side (in Fig. 1) corresponds to the second shoji screen of the present invention.

障子４は、それぞれ横方向に延びる上框４１と下框４２と、障子４の戸先側（図１における右側）に縦方向に延びる縦框である突合せ框４３と、障子４の戸尻側（図１における左側）に縦方向に延びる縦框４４とで矩形に枠組みされた内側に、ガラスＧが収容されている。また、障子５は、それぞれ横方向に延びる上框５１と下框５２と、障子５の戸先側（図１における左側）に縦方向に延びる縦框である突合せ框５３と、障子５の戸尻側（図１における右側）に縦方向に延びる縦框５４とで矩形に枠組みされた内側に、ガラスＧが収容されている。なお、図１における障子４の突合せ框４３は、詳細には後述するが、障子５の突合せ框５３に隠れて見えていない。中央の障子４と障子５とは、それぞれの突合せ框４３、５３同士が突き合わされることにより閉じられ、中央部で突き合わされた突合せ框４３、５３により、突合せ部１０が構成される。 The shoji screen 4 is framed in a rectangle by an upper frame 41 and a lower frame 42 that extend horizontally, a butt frame 43 that is a vertical frame extending vertically on the door end side of the shoji screen 4 (right side in Fig. 1), and a vertical frame 44 that extends vertically on the door end side of the shoji screen 4 (left side in Fig. 1), and the glass G is housed inside. The shoji screen 5 is framed in a rectangle by an upper frame 51 and a lower frame 52 that extend horizontally, a butt frame 53 that is a vertical frame extending vertically on the door end side of the shoji screen 5 (left side in Fig. 1), and a vertical frame 54 that extends vertically on the door end side of the shoji screen 5 (right side in Fig. 1), and the glass G is housed inside. The butt frame 43 of the shoji screen 4 in Fig. 1 is hidden by the butt frame 53 of the shoji screen 5, which will be described in detail later, and cannot be seen. The central shoji screens 4 and 5 are closed by butting their respective butt frames 43 and 53 together, and the butt frame 10 is formed by the butt frames 43 and 53 that are butted together in the center.

障子３、６は、それぞれ横方向に延びる上框３１、６１と下框３２、６２と、それぞれ縦方向に延びる縦框３３、３４、６３、６４とで矩形に枠組みされた内側に、ガラスＧが収容されている。図１において、障子３の戸先側（図１における右側）に配置される縦框３３は、障子４の縦框４４に隠れて見えていない。また、障子６の戸先側（図１における左側）に配置される縦框６３は、障子５の縦框５４に隠れて見えていない。障子３、６のそれぞれ縦框３４、６４の屋内側及び屋外側には、開閉操作のための手掛け部３５、６５が、縦框３４、６４の延び方向（図１における上下方向）に沿って凹設されている。 The shoji screens 3 and 6 are framed in a rectangle by upper and lower frames 31 and 61, which extend horizontally, and vertical frames 33, 34, 63 and 64, which extend vertically. In Fig. 1, the vertical frame 33 located on the door end side of the shoji screen 3 (right side in Fig. 1) is hidden by the vertical frame 44 of the shoji screen 4 and is not visible. The vertical frame 63 located on the door end side of the shoji screen 6 (left side in Fig. 1) is hidden by the vertical frame 54 of the shoji screen 5 and is not visible. The vertical frames 34 and 64 of the shoji screens 3 and 6 have handles 35 and 65 for opening and closing the screen recessed on the indoor and outdoor sides along the extension direction of the vertical frames 34 and 64 (up and down direction in Fig. 1).

建具１の縦方向の中ほどには、障子３と障子４とに亘り、及び障子５と障子６とに亘り、それぞれ両者を施錠するクレセント錠７、７が取り付けられている。また、障子３、６の下框３２、６２には、それぞれ障子４及び障子５を施錠する補助ロック機構８、８が取り付けられている。 Crescent locks 7, 7 are attached to the vertical middle of the fitting 1, spanning shoji screens 3 and 4, and shoji screens 5 and 6, respectively, to lock both screens. In addition, auxiliary locking mechanisms 8, 8 are attached to the bottom frames 32, 62 of the shoji screens 3, 6, respectively, to lock shoji screens 4 and 5.

次に、図２を用いて、障子４、５の概略形状及び障子５の開閉操作について説明する。図２は、建具１の開閉操作を説明する模式図であり、平面視した障子３～６を示している。図２において、障子３～６がスライド移動する２本のレールの図示は省略した。
障子４の戸先側に配置される突合せ框４３は、見込み方向（屋内外方向であり、図２における上下方向）の屋外側に向けて張り出す形状に形成されている。具体的には、突合せ框４３は、屋外側に向けて略垂直方向に突出して張り出していると共に、その張り出した部位が、障子５の突合せ框５３の屋外側の見付け面５３ｂ（図３参照）を覆うように、障子５側に変位した形状に形成されている。 Next, the general shape of the shoji screens 4 and 5 and the opening and closing operation of the shoji screen 5 will be described with reference to Fig. 2. Fig. 2 is a schematic diagram for explaining the opening and closing operation of the fitting 1, and shows the shoji screens 3 to 6 in a plan view. In Fig. 2, the illustration of the two rails along which the shoji screens 3 to 6 slide is omitted.
The butt frame 43 arranged on the door end side of the shoji screen 4 is formed in a shape that protrudes toward the outdoor side in the projection direction (the indoor/outdoor direction, the up-down direction in Fig. 2). Specifically, the butt frame 43 protrudes in a substantially vertical direction toward the outdoor side, and the protruding portion is formed in a shape displaced toward the shoji screen 5 so as to cover the outdoor side visible surface 53b (see Fig. 3) of the butt frame 53 of the shoji screen 5.

障子４の戸尻側の縦框４４は、見込み方向の屋内側に向けて張り出す形状に形成されている。具体的には、縦框４４は、突合せ框４３とは逆に、屋内側に向けて略垂直方向に突出して張り出している。この縦框４４は、障子３の縦框３３とオーバーラップする位置に配置されることにより、障子３の縦框３３を屋内側から覆い隠すように配置されている。 The vertical frame 44 on the end side of the shoji screen 4 is formed in a shape that protrudes toward the indoor side in the front direction. Specifically, the vertical frame 44 protrudes in a substantially vertical direction toward the indoor side, opposite to the butt frame 43. This vertical frame 44 is positioned so that it overlaps with the vertical frame 33 of the shoji screen 3, thereby obscuring the vertical frame 33 of the shoji screen 3 from the indoor side.

一方、障子５の戸先側に配置される突合せ框５３は、障子４の突合せ框４３とは逆に、見込み方向の屋内側に向けて張り出す形状に形成されている。具体的には、突合せ框５３は、屋内側に向けて略垂直方向に突出するように張り出していると共に、その張り出した部位が、障子４の突合せ框４３の屋内側の見付け面４３ｂ（図３参照）を覆うように、障子４側に変位した形状に形成されている。 On the other hand, the butt frame 53 located on the door end of the shoji screen 5 is formed in a shape that protrudes toward the indoor side in the projection direction, the opposite of the butt frame 43 of the shoji screen 4. Specifically, the butt frame 53 protrudes so as to protrude in a substantially vertical direction toward the indoor side, and the protruding portion is formed in a shape displaced toward the shoji screen 4 so as to cover the indoor side visible surface 43b (see Figure 3) of the butt frame 43 of the shoji screen 4.

障子５の戸尻側の縦框５４も、突合せ框５３と同様に、見込み方向の屋内側に向けて張り出す形状に形成されている。具体的には、縦框５４は、突合せ框５３と同様に、屋内側に向けて略垂直方向に突出するように張り出している。この障子５の縦框５４は、障子６の縦框６３とオーバーラップする位置に配置されることにより、障子６の縦框６３を屋内側から覆い隠すように配置されている。 The vertical frame 54 on the end side of the shoji screen 5 is also formed in a shape that protrudes toward the indoor side in the projection direction, just like the butt frame 53. Specifically, the vertical frame 54 protrudes almost vertically toward the indoor side, just like the butt frame 53. The vertical frame 54 of this shoji screen 5 is positioned so that it overlaps with the vertical frame 63 of the shoji screen 6, thereby obscuring the vertical frame 63 of the shoji screen 6 from the indoor side.

障子５を屋内側から開閉操作する場合は、屋内側に張り出している障子５の突合せ框５３を手で掴んで、白抜き矢印の方向にスライド移動させる。即ち、障子５のスライド移動は、突合せ框５３を手で掴むことによって行われる。 When opening and closing the shoji screen 5 from inside the house, the butt frame 53 of the shoji screen 5 that protrudes inside the house is grasped with the hand and slid in the direction of the outlined arrow. In other words, the sliding movement of the shoji screen 5 is performed by grasping the butt frame 53 with the hand.

次に、この障子４、５の突合せ框４３、５３の更に具体的な構成について図３を用いて説明する。図３は、図１に示す建具１における障子４と障子５との突合せ部１０の拡大横断面図である。図３において、障子４と障子５は、同一のレール２２１上をスライド移動可能に配置されている。 Next, the specific structure of the butt frames 43, 53 of the shoji screens 4, 5 will be described with reference to FIG. 3. FIG. 3 is an enlarged cross-sectional view of the butt portion 10 of the shoji screens 4 and 5 in the fitting 1 shown in FIG. 1. In FIG. 3, the shoji screens 4 and 5 are arranged so that they can slide on the same rail 221.

障子４の突合せ框４３は、アルミ等の金属材により押出し成形され、スペーサＳによって間隔を空けて配置された３枚のガラスＧを、ガスケット４ａを介して収容している。突合せ框４３の突合せ面（障子５と突き合わされる面）４３ａには、障子５に向けて略垂直に立ち上がる立壁部４３１を一体に有している。突合せ框４３の屋内側の見付け面４３ｂは、樹脂製カバー４３２によって覆われている。これにより、障子４は断熱性に優れる。 The butt frame 43 of the shoji screen 4 is extruded from a metal material such as aluminum, and houses three pieces of glass G spaced apart by spacers S, via a gasket 4a. The butt face 43a of the butt frame 43 (the face that butts against the shoji screen 5) has an integral vertical wall 431 that rises roughly vertically toward the shoji screen 5. The visible face 43b on the indoor side of the butt frame 43 is covered by a resin cover 432. This gives the shoji screen 4 excellent thermal insulation.

突合せ框４３は、屋外側に向けて突出して張り出した框被覆部４３３を一体に有している。框被覆部４３３は、突合せ框４３の延び方向（図１における上下方向）に沿って形成されている。框被覆部４３３は、障子４のガラスＧの面（ガラスＧの屋外側の面）に対して略垂直方向に立ち上がる第１壁部４３３ａと、この第１壁部４３３ａの屋外側の端部から障子５側に向けて屈曲し、障子４のガラスＧの面と略平行に延びる第２壁部４３３ｂと、この第２壁部４３３ｂの端部から障子５側に向けて屈曲し、第１壁部４３３ａと略平行に延びる第３壁部４３３ｃと、この第３壁部４３３ｃの端部から突合せ面４３ａに向けて延びる第４壁部４３３ｄと、を一体に有し、横断面が略矩形状に形成されている。 The butt frame 43 has an integral frame covering portion 433 that protrudes toward the outdoor side. The frame covering portion 433 is formed along the extension direction of the butt frame 43 (the vertical direction in FIG. 1). The frame covering portion 433 has a first wall portion 433a that rises approximately perpendicular to the surface of the glass G of the shoji screen 4 (the surface of the glass G facing the outdoor side), a second wall portion 433b that bends from the outdoor end of the first wall portion 433a toward the shoji screen 5 side and extends approximately parallel to the surface of the glass G of the shoji screen 4, a third wall portion 433c that bends from the end of the second wall portion 433b toward the shoji screen 5 side and extends approximately parallel to the first wall portion 433a, and a fourth wall portion 433d that extends from the end of the third wall portion 433c toward the butt surface 43a, and has a substantially rectangular cross section.

第２壁部４３３ｂの表面は、突合せ框４３及び框被覆部４３３の屋外側の見付け面を形成する。この第２壁部４３３ｂは、突合せ框４３の突合せ面４３ａよりも障子５側に突出している。第２壁部４３３ｂは、突合せ面４３ａよりも障子５側に向けて大きく延び、障子５の突合せ框５３の屋外側の見付け面５３ｂの全体を実質的に覆い隠している。これにより、突合せ框４３の屋外側は、障子５側に変位した形状とされる。このため、建具１を屋外側から観察した場合、突合せ部１０の幅は、実質的に障子４の突合せ框４３の見付け面の幅（第２壁部４３３ｂの幅）だけの細幅状となり、建具１の意匠性向上が図られる。 The surface of the second wall portion 433b forms the outdoor facing surface of the butt frame 43 and the frame covering portion 433. This second wall portion 433b protrudes further toward the shoji 5 side than the butt surface 43a of the butt frame 43. The second wall portion 433b extends farther toward the shoji 5 side than the butt surface 43a, and essentially covers and conceals the entire outdoor facing surface 53b of the butt frame 53 of the shoji 5. As a result, the outdoor side of the butt frame 43 is displaced toward the shoji 5 side. Therefore, when the fitting 1 is observed from the outdoor side, the width of the butt portion 10 is narrow, substantially the width of the facing surface of the butt frame 43 of the shoji 4 (the width of the second wall portion 433b), improving the design of the fitting 1.

一方、障子５の突合せ框５３も、スペーサＳによって間隔を空けて配置された３枚のガラスＧを、ガスケット５ａを介して収容している。突合せ框５３の屋外側の見付け面５３ｂは、突合せ面５３ａよりも障子４側に向けて延長され、障子４の突合せ框４３の突合せ面５３ａに形成された立壁部４３１とオーバーラップしている。延長された見付け面５３ｂの先端には、第１気密材５３１が取り付けられ、立壁部４３１との間を封止している。 The butt frame 53 of the shoji screen 5 also houses three pieces of glass G spaced apart by spacers S, via a gasket 5a. The outdoor-facing face 53b of the butt frame 53 extends further toward the shoji screen 4 than the butt face 53a, and overlaps with the vertical wall portion 431 formed on the butt face 53a of the butt frame 43 of the shoji screen 4. A first airtight material 531 is attached to the tip of the extended face 53b, sealing the space between it and the vertical wall portion 431.

また、突合せ框５３は、突合せ面５３ａの屋内側の端部に、断熱のためのブリッジ部５３２を介して、屋内側に向けて突出して張り出した框被覆部５３３を有している。框被覆部５３３は、ブリッジ部５３２と接続され、アルミ等の金属材により一体に押出し成形された框被覆部本体５３４と、この框被覆部本体５３４の外側を覆う樹脂製カバー５３５とで構成される。 The butt frame 53 also has a frame covering part 533 that protrudes toward the indoor side at the indoor end of the butt surface 53a via a bridge part 532 for insulation. The frame covering part 533 is connected to the bridge part 532 and is composed of a frame covering part main body 534 that is integrally extruded from a metal material such as aluminum, and a resin cover 535 that covers the outside of the frame covering part main body 534.

框被覆部本体５３４は、障子５のガラスＧの面（ガラスＧの屋内側の面）に対して略垂直方向に立ち上がる第１壁部５３４ａと、この第１壁部５３４ａの屋外側の端部から障子４側に向けて屈曲し、障子５のガラスＧの面と略平行に延びる第２壁部５３４ｂと、この第２壁部５３４ｂの障子４側の端部から屋外側に向けて屈曲し、第１壁部５３４ａと略平行に延びる第３壁部５３４ｃと、この第３壁部５３４ｃの屋外側の端部から障子５側に向けて屈曲し、第２壁部５３４ｂと略平行に延びる第４壁部５３４ｄと、この第４壁部５３４ｄの障子５側の端部から屋外側に向けて屈曲し、ブリッジ部５３２と連結される第５壁部５３４ｅとを一体に有する。 The frame covering body 534 is integrally formed with a first wall portion 534a that rises in a direction substantially perpendicular to the surface of the glass G of the shoji screen 5 (the surface of the glass G facing the interior), a second wall portion 534b that bends from the outdoor end of the first wall portion 534a toward the shoji screen 4 side and extends substantially parallel to the surface of the glass G of the shoji screen 5, a third wall portion 534c that bends from the shoji screen 4 side end of the second wall portion 534b toward the outdoor side and extends substantially parallel to the first wall portion 534a, a fourth wall portion 534d that bends from the outdoor end of the third wall portion 534c toward the shoji screen 5 side and extends substantially parallel to the second wall portion 534b, and a fifth wall portion 534e that bends from the shoji screen 5 side end of the fourth wall portion 534d toward the outdoor side and is connected to the bridge portion 532.

このうちの第２壁部５３４ｂは、突合せ框５３の突合せ面５３ａよりも障子４側に突出している。第２壁部５３４ｂは、障子４側に向けてガラスＧの面と平行に大きく延び、障子４の突合せ框４３の屋外側の見付け面４３ｂを構成する樹脂製カバー４３２のほぼ全体を実質的に覆い隠している。これにより、突合せ框５３は、障子４側に変位した形状とされる。突合せ框５３の樹脂製カバー５３５は、第１壁部５３４ａ、第２壁部５３４ｂ及び第３壁部５３４ｃに亘って、これらの外側（屋内側）を覆っている。このため、建具１を屋内側から観察した場合、突合せ部１０の幅は、図１に示すように、実質的に障子５の突合せ框５３の見付け面（樹脂製カバー５３５の屋内側の面）の幅だけの細幅状となり、建具１の意匠性向上が図られる。また、樹脂製カバー５３５を有することにより、障子５は断熱性に優れる。 Of these, the second wall portion 534b protrudes further toward the shoji 4 side than the abutment surface 53a of the butt frame 53. The second wall portion 534b extends largely parallel to the surface of the glass G toward the shoji 4 side, and substantially covers and conceals almost the entirety of the resin cover 432 that constitutes the outdoor-facing visible surface 43b of the butt frame 43 of the shoji 4. This gives the butt frame 53 a shape that is displaced toward the shoji 4 side. The resin cover 535 of the butt frame 53 covers the outside (indoor side) of the first wall portion 534a, the second wall portion 534b, and the third wall portion 534c. Therefore, when the fitting 1 is observed from the indoor side, the width of the butt joint 10 is narrow, as shown in FIG. 1, and is essentially the same as the width of the visible surface of the butt frame 53 of the shoji screen 5 (the indoor surface of the resin cover 535), improving the design of the fitting 1. In addition, by having the resin cover 535, the shoji screen 5 has excellent heat insulation properties.

突合せ框５３の突合せ面５３ａには、第２気密材５３６が収容され、突合せ框４３、５３の突合せ面４３ａ、５３ａ同士の間を封止している。 A second airtight material 536 is housed in the butt surface 53a of the butt frame 53, sealing the gap between the butt surfaces 43a, 53a of the butt frames 43, 53.

第４壁部５３４ｄと障子４の突合せ框４３の樹脂製カバー４３２との間には、大きなスペース１００が空けられている。このスペース１００は、障子５の突合せ框５３の框被覆部５３３と、障子４の突合せ框４３の屋内側の見付け面４３ｂとが対向する部位に設けられている。具体的には、このスペース１００は、障子５を開閉操作する際に框被覆部５３３を掴んだ際に、指が挿入し得る程度の大きさを有している。 A large space 100 is provided between the fourth wall portion 534d and the resin cover 432 of the butt frame 43 of the shoji screen 4. This space 100 is provided in the area where the frame covering portion 533 of the butt frame 53 of the shoji screen 5 faces the indoor facing surface 43b of the butt frame 43 of the shoji screen 4. Specifically, this space 100 is large enough for a finger to be inserted when grasping the frame covering portion 533 when opening or closing the shoji screen 5.

このスペース１００に、ゴム等の弾性材料からなる緩衝部材９が設けられている。本実施形態の緩衝部材９は、框被覆部５３３の第４壁部５３４ｄにおける屋外側の面に、突合せ框４３の屋内側の見付け面４３ｂに向けて突出するように取り付けられている。緩衝部材９は、框被覆部５３３における障子４側に配置される戸先端面５３３ａと略平行に延び、戸先端面５３３ａと略面一状に配置される側面部９１を有している。従って、緩衝部材９は、スペース１００において、戸先端面５３３ａに、障子４側（図３における左側）に向けて露出するように配置されている。側面部９１は、戸先端面５３３ａと略面一状であるため、図３に示すように、障子４、５が閉じられた状態では、スペース１００を塞ぐように機能する。このため、突合せ部１０の屋内側からの意匠性が損なわれるおそれはない。 A buffer member 9 made of an elastic material such as rubber is provided in this space 100. In this embodiment, the buffer member 9 is attached to the outdoor surface of the fourth wall portion 534d of the frame covering portion 533 so as to protrude toward the indoor surface 43b of the butt frame 43. The buffer member 9 extends approximately parallel to the door tip surface 533a arranged on the shoji 4 side of the frame covering portion 533, and has a side portion 91 arranged approximately flush with the door tip surface 533a. Therefore, the buffer member 9 is arranged in the space 100 so as to be exposed on the door tip surface 533a toward the shoji 4 side (left side in FIG. 3). Since the side portion 91 is approximately flush with the door tip surface 533a, it functions to block the space 100 when the shoji 4 and 5 are closed, as shown in FIG. 3. Therefore, there is no risk of impairing the design of the butt portion 10 from the indoor side.

緩衝部材９は、図３に示すように、障子４、５が閉じられた際に、突合せ框４３の屋内側の見付け面４３ｂ（樹脂製カバー４３２）と当接する突片部９２を一体に有している。これにより、緩衝部材９は、突合せ框４３の屋内側の見付け面４３ｂとの間を封止する第３気密材としても機能している。 As shown in FIG. 3, the cushioning member 9 has an integral protruding piece 92 that abuts against the indoor facing surface 43b (resin cover 432) of the butt frame 43 when the screens 4 and 5 are closed. This allows the cushioning member 9 to also function as a third airtight material that seals the gap with the indoor facing surface 43b of the butt frame 43.

更に、緩衝部材９は、中空部９３を有している。このため、緩衝部材９は、中空部９３内の空気により形状保持性に優れ、意匠性を損なうことがないと共に、外部から力が加わった際に、中空部９３（空気）が圧縮されることにより、適度な弾力性（クッション性）を有して変形可能である。 The cushioning member 9 further has a hollow section 93. Therefore, the cushioning member 9 has excellent shape retention due to the air inside the hollow section 93, and does not impair the design, and when an external force is applied, the hollow section 93 (air) is compressed, allowing the cushioning member 9 to deform with appropriate elasticity (cushioning properties).

図４に示すように、この緩衝部材９を有する障子５の突合せ框５３を手で掴んで開閉操作する場合は、指先が緩衝部材９の側面部９１と当接する。このとき、緩衝部材９は、指先が緩衝部材９の側面部９１上に載っていること（指を挟んでしまう位置にはないこと）を、開閉操作者に対して容易に知覚させることができる。このため、突合せ框５３を掴んだまま障子４、５を閉じ合せた際に、突合せ框５３と障子４の屋内側の見付け面４３ｂとの間に指を挟んでしまうことを防止することができる。また、開閉操作者の指が、障子４の屋内側の見付け面４３ｂに近接し過ぎても、緩衝部材９が容易に弾性変形するため、指を痛めるおそれはなく、操作性が向上する。 As shown in FIG. 4, when the butt frame 53 of the shoji screen 5 having this buffer member 9 is grasped by hand to open or close the screen, the fingertips come into contact with the side surface 91 of the buffer member 9. At this time, the buffer member 9 allows the opening/closing operator to easily recognize that the fingertips are resting on the side surface 91 of the buffer member 9 (not in a position where the fingers will be pinched). This makes it possible to prevent the fingers from being pinched between the butt frame 53 and the visible surface 43b on the indoor side of the shoji screen 4 when the shoji screen 4, 5 are closed while grasping the butt frame 53. Also, even if the opening/closing operator's fingers get too close to the visible surface 43b on the indoor side of the shoji screen 4, the buffer member 9 easily elastically deforms, so there is no risk of injuring the fingers, and operability is improved.

緩衝部材９は、障子４の屋内側の見付け面４３ｂに取り付けられてもよいが、本実施形態に示すように、障子５の突合せ框５３側に取り付けられる場合は、障子４又は障子５を開操作した際に、緩衝部材９が屋内側に露出することがなく、屋内側から直接目視されないため、建具１の意匠性を更に良好にすることができる。 The cushioning member 9 may be attached to the visible surface 43b on the indoor side of the shoji screen 4, but as shown in this embodiment, if it is attached to the butt frame 53 side of the shoji screen 5, the cushioning member 9 will not be exposed to the indoor side when the shoji screen 4 or 5 is opened, and will not be directly visible from the indoor side, further improving the design of the fitting 1.

図１に示した建具１の両端に配置される障子３、６は、枠体２に移動不能に固定されていてもよい。また、本発明における建具１の障子は４枚に限定されず、少なくとも２枚の障子が突き合わされて閉じられるように構成されるものであればよい。 The shoji screens 3 and 6 arranged at both ends of the fitting 1 shown in FIG. 1 may be immovably fixed to the frame 2. Furthermore, the number of shoji screens of the fitting 1 in the present invention is not limited to four, and it is sufficient that at least two shoji screens are butted together to be closed.
