In the lower frame 12, floor members 124 are detachably attached to both sides of the protrusion 12A. The floor member 124 has a flat upper surface, and is configured such that the upper surface and the protrusion 121A are at substantially the same height. With such a configuration, the floor on which the shoji 21 to 23 slide can be made to have a flat top surface and a clean appearance, and can also be adapted to barrier-free. Further, since the floor member 124 is detachable, the lower frame 12 can be easily cleaned by removing the floor member 124 as appropriate.
In the present embodiment, the cover member 121 and the floor member 124 are used to make the floor surface flat. However, the rail corresponding to each shoji is also provided on the lower frame 12 side, similarly to the upper frame 11 side. It is good also as a structure which each is provided and each shoji slides on these rails. In this case, as will be described later, a rail provided on the lower frame side may be used as a reinforcing portion.

図４に示すように、各縦枠１３には、互いに向き合う方向に突出する呑込部１３０がそれぞれ形成されている。室内側から見て、右側の縦枠１３Ｒの呑込部１３０Ｒは、外障子２３の戸先框２３２を呑込んでおり、左側の縦枠１３Ｌの呑込部１３０Ｌは、内障子２１の戸先框２１１を呑込んでいる。また、各呑込部１３０Ｒ，１３０Ｌは、建物２の開口部２Ａ近傍の壁体４に係合している。 As shown in FIG. 4, each vertical frame 13 is formed with a ridge portion 130 that protrudes in a direction facing each other. When viewed from the indoor side, the insertion portion 130R of the right vertical frame 13R inserts the door rod 232 of the outer frame 23, and the insertion portion 130L of the left vertical frame 13L is the door edge of the inner frame 21. It contains coffee 211. In addition, each sandwiched portion 130 R, 130 L is engaged with the wall body 4 near the opening 2 A of the building 2.

呑込部１３０Ｒによる戸先框２３２の呑込寸法は、外障子２３の戸先框２３２の見付寸法と略同じである。また、呑込部１３０Ｌによる戸先框２１１の呑込寸法は、内障子２１の戸先框２１１の見付寸法と略同じである。このため、障子２０を閉じた状態では、室内側から見て、戸先框２１１，２３２が縦枠１３内に程よく呑み込まれて隠れることとなり、複層ガラス２８を通した視界が拡がるため、室内側からの開放感が向上する。 The insertion dimension of the door toe 232 by the insertion part 130 R is substantially the same as the finding dimension of the door toe 232 of the external shoji 23. Further, the insertion size of the door toe 211 by the insertion unit 130 L is substantially the same as the finding size of the door toe 211 of the inner shoji 21. For this reason, in the state where the shoji 20 is closed, the door toe 211 and 232 are appropriately swallowed and hidden in the vertical frame 13 when viewed from the indoor side, and the field of view through the multilayer glass 28 is expanded. A feeling of opening from the inside is improved.

また、各縦枠１３には、内障子２１の摺動箇所に対応する位置に設けられた第１ヒレ部１３１と、第１ヒレ部１３１よりも室外側に設けられた第２ヒレ部１３２とがそれぞれ形成されている。
図３の左側に示す縦枠１３Ｌにおいて、内障子２１を閉じた状態で、第１ヒレ部１３１は、内障子２１の戸先框２１１の後述する引寄片８０の溝部８０Ａに係合する。内障子２１の戸先框２１１には、内障子２１を閉じた状態で、竪枠１３Ｌに形成された第１ヒレ部１３１に当接するシール材１３７が設けられている。また、第２ヒレ部１３２には、シール材１３４が取り付けられ、内障子２１を閉じた際にシール材１３４が内障子２１の戸先側に当接する。 Further, each vertical frame 13 includes a first fin portion 131 provided at a position corresponding to the sliding position of the inner cot 21, and a second fin portion 132 provided on the outdoor side of the first fin portion 131. Are formed respectively.
In the vertical frame 13L shown on the left side of FIG. A seal member 137 that contacts the first fin portion 131 formed on the collar frame 13L is provided in the door-end collar 211 of the inner collar 21 in a state where the inner collar 21 is closed. In addition, a sealing material 134 is attached to the second fin portion 132, and the sealing material 134 comes into contact with the door end side of the inner shroud 21 when the inner shroud 21 is closed.

一方、図３の右側に示す縦枠１３Ｒには、閉じた状態の外障子２３の戸先框２３２の室内側に、第１ヒレ部１３１および第２ヒレ部１３２を覆うようなアタッチメント部材１３３が着脱自在に取り付けられている。 On the other hand, in the vertical frame 13R shown on the right side of FIG. 3, an attachment member 133 that covers the first fin portion 131 and the second fin portion 132 is provided on the indoor side of the door toe 232 of the closed shoji 23. It is detachably attached.

アタッチメント部材１３３は、平面視略Ｆ字状に形成され、室内外方向に延びて、外障子２３の戸先框２３２の見込方向側の面と略面一となるように構成された被覆部１３３Ａを備えている。被覆部１３３Ａの室内側端部には、図中右側へ折り曲げられた係合部１３３Ｂが形成され、この係合部１３３Ｂが呑込部１３０Ｒに係合するとともに、被覆部１３３Ａから延びる２つの係合板１３３Ｃ，１３３Ｄが第１ヒレ部１３１、第２ヒレ部１３２に係合することでアタッチメント部材１３３が取り付けられている。 The attachment member 133 is formed in a substantially F shape in plan view, extends in the indoor / outdoor direction, and is configured to be substantially flush with the surface on the prospective direction side of the door toe 232 of the external door 23. It has. An engagement portion 133B bent to the right side in the drawing is formed at the indoor side end of the covering portion 133A. The engagement portion 133B engages with the insertion portion 130R and extends from the covering portion 133A. The attachment member 133 is attached by the plywoods 133 C and 133 D engaging the first fin portion 131 and the second fin portion 132.

このような構成により、図１に示すように、外障子２３の戸先框２３２の室内側の面がアタッチメント部材１３３の被覆部１３３Ａによって殆ど隠れるため、見た目がすっきりとし、室内側からの開放感をさらに向上できる。 With such a configuration, as shown in FIG. 1, since the indoor side surface of the door toe 232 of the shoji 23 is almost hidden by the covering portion 133 A of the attachment member 133, the appearance is clear and the open feeling from the indoor side Can be further improved.

また、縦枠１３（１３Ｒ，１３Ｌ）には、外障子２３の摺動箇所に対応する位置に第３ヒレ部１３５がそれぞれ形成されている。右側の縦枠１３Ｒ側において、外障子２３を閉じた状態で、第３ヒレ部１３５は、外障子２３の戸先框２３２の後述する引寄片８０の溝部８０Ａに係合する。また、外障子２３の戸先框２３２には、外障子２３を閉じた状態で、縦枠１３Ｒに形成された第３ヒレ部１３５に当接するシール材１３６が取り付けられている。 Further, in the vertical frame 13 (13R, 13L), a third fin portion 135 is formed at a position corresponding to the sliding position of the external obstacle 23, respectively. On the right vertical frame 13 R side, the third fin portion 135 engages with a groove portion 80 A of an attracting piece 80, which will be described later, of the door toe 232 of the outer obstacle 23 with the outer obstacle 23 closed. In addition, a seal material 136 that is in contact with the third fin portion 135 formed on the vertical frame 13R is attached to the door rod 232 of the external shoji 23 in a state in which the external shoji 23 is closed.

以上のように、アタッチメント部材１３３やシール材１３４は、いずれか一方の縦枠１３側にのみ設けられている。このため、例えば、図６に示すように、アタッチメント部材１３３やシール材１３４を他方の縦枠１３側に付け替えることにより、建物２から枠体１０を取り外すことなく、当該枠体１０を使用したまま、障子２０を左右勝手の異なる障子に交換するだけで、比較的簡単に障子の左右勝手を替えることができる。 As described above, the attachment member 133 and the sealing material 134 are provided only on one of the vertical frames 13 side. For this reason, for example, as shown in FIG. 6, by changing the attachment member 133 and the sealing material 134 to the other vertical frame 13 side, the frame body 10 is used without removing the frame body 10 from the building 2. The left and right hand of the shoji can be changed comparatively easily by simply replacing the shoji 20 with a different shoji.

次に、障子２０について詳説する。
図３に示すように、各障子２１〜２３の上框２４の上部には、シール材２９を介してレール１１Ａ，１１Ｂ，１１Ｃに当接する溝部２４Ａが形成されている。また、溝部２４Ａには、左右の竪框２６側の端部に上側摺動片（図示略）がそれぞれ設けられ、これらの２つの上側摺動片はレール１１Ａ，１１Ｂ，１１Ｃに係合している。また、下框２５下側の左右の竪框２６側の端部にも、下側摺動片（図示略）がそれぞれ設けられている。これらの２つの下側摺動片は、カバー部材１２１の突条部１２１Ａに係合している。前記上側摺動片とレール１１Ａ，１１Ｂ，１１Ｃの係合と、前記下側摺動片と突条部１２１Ａの係合とにより、各障子２１〜２３の見付方向への振動が防止されている。 Next, the shoji 20 will be described in detail.
As shown in FIG. 3, a groove portion 24 A that contacts the rails 11 A, 11 B, and 11 C via the seal material 29 is formed in the upper part of the upper collar 24 of each shoji 21 to 23. The groove portion 24A is provided with upper sliding pieces (not shown) at the ends of the left and right flanges 26, and these two upper sliding pieces are engaged with the rails 11A, 11B, and 11C. Yes. In addition, lower sliding pieces (not shown) are also provided at the ends of the left and right side of the lower side of the lower rod 25.

図３，図４に示すように、中障子２２の上框２４には、３枚の障子２１〜２３を連動して摺動させるための連動部材５０が設けられている。また、図３に示すように、各障子２１〜２３の下框２５には、溝部２５Ａが形成されている。下框２５の溝部２５Ａの位置には、下枠１２に設けられたカバー部材１２１の突条部１２１Ａに沿って回転する戸車４５が設けられている。下枠１２に設けられたカバー部材１２１の突条部１２１Ａに沿って、戸車４５が回転することにより、障子２０を、図４に示す閉じた状態と、図５に示す開いた状態との間で滑らかに移動させることができる。 As shown in FIGS. 3 and 4, the upper arm 24 of the middle shoji 22 is provided with an interlocking member 50 for sliding the three shoji 21 to 23 in an interlocking manner. Moreover, as shown in FIG. 3, the groove part 25A is formed in the lower arm 25 of each shoji 21-21. At the position of the groove portion 25 A of the lower rod 25, a door wheel 45 that rotates along the protruding portion 121 A of the cover member 121 provided on the lower frame 12 is provided. When the door wheel 45 rotates along the protrusion 121A of the cover member 121 provided on the lower frame 12, the shoji 20 is placed between the closed state shown in FIG. 4 and the open state shown in FIG. Can be moved smoothly.

図７は、連動部材５０を示す横断面図である。図７に示すように、連動部材５０は、上框２４内に収容される本体５１と、本体５１の両端にそれぞれ取り付けられたリール５２と、リール５２間に掛け渡されたリング状のワイヤ５３と、ワイヤ５３に固着された２つの誘導軸５４（５４Ａ，５４Ｂ）とを備えている。一方の誘導軸部材５４Ａは外障子２３側に突出し、他方の誘導軸部材５４Ｂは内障子２１側に突出している。これらの誘導軸５４は、誘導軸部材５４Ａが図中右側のリール５２近傍に位置する場合には、誘導軸部材５４Ｂが図中左側のリール５２の近傍に位置するように、ワイヤ５３に固着されている。 FIG. 7 is a cross-sectional view showing the interlocking member 50. As shown in FIG. 7, the interlocking member 50 includes a main body 51 accommodated in the upper collar 24, reels 52 attached to both ends of the main body 51, and a ring-shaped wire 53 spanned between the reels 52. And two guide shafts 54 (54A, 54B) fixed to the wire 53. One guide shaft member 54A protrudes toward the outer obstacle 23, and the other guide shaft member 54B protrudes toward the inner obstacle 21. When the guide shaft member 54A is positioned in the vicinity of the right reel 52 in the drawing, these guide shafts 54 are fixed to the wires 53 so that the guide shaft member 54B is positioned in the vicinity of the left reel 52 in the drawing. ing.

従って、例えば、一方の誘導軸部材５４Ａが図中の左方向に移動すると、リール５２間に掛け渡されたワイヤ５３が回転し、ワイヤ５３に固着された、他方の誘導軸部材５４Ｂが図中の右方向に移動する。誘導軸部材５４Ａは、外障子２３の召合框２３１に設けられた受部材６０（６０Ｒ）に係合し、誘導軸部材５４Ｂは、内障子２１の召合框２１２に設けられた受部材６０（６０Ｌ）に係合する。 Therefore, for example, when one guide shaft member 54A moves to the left in the drawing, the wire 53 stretched between the reels 52 rotates, and the other guide shaft member 54B fixed to the wire 53 is shown in the drawing. Move to the right. The guide shaft member 54 A engages with a receiving member 60 (60 R) provided on the summing cage 231 of the external obstacle 23, and the guide shaft member 54 B is received by the receiving member 60 provided on the summing cage 212 of the inner hand child 21. Engage with (60L).

次に、連動部材５０の動作について説明する。図８は、連動部材５０によって障子２１〜２３が連動して動く様子を模式的に示す横断面図であり、（Ａ）は３枚の障子２１〜２３により室内外空間を連通する開口部を閉じた状態を、（Ｂ）は開口部の一部を開いた状態を、（Ｃ）は開口部を閉じた状態を示している。 Next, the operation of the interlocking member 50 will be described. FIG. 8 is a cross-sectional view schematically showing how the shojis 21 to 23 move in conjunction with the interlocking member 50. FIG. 8A shows an opening that communicates the indoor / outdoor space with the three shojis 21 to 23. (B) shows a state where a part of the opening is opened, and (C) shows a state where the opening is closed.

図８（Ａ）に示す障子２１〜２３を閉じた状態から、図８（Ｂ）に示すように、内障子２１を矢印Ａの方向に摺動させると、誘導軸部材５４Ｂが矢印Ａの方向に移動して、リール５２間に掛け渡されたワイヤ５３が回転し、誘導軸部材５４Ａが矢印Ｂの方向に移動する。誘導軸部材５４Ａが矢印Ｂの方向に移動すると、外障子２３が固定された状態となっていることから、中障子２２が矢印Ａの方向に移動する。従って、内障子２１と中障子２２とが、図中の矢印Ａの方向に移動して、最終的には、図８（Ｃ）に示すように、３枚の障子２１〜２３が重なった状態となり、図５に示す開放状態となる。 When the shoji 21 is slid in the direction of the arrow A as shown in FIG. 8B from the state in which the shoji 21 to 23 shown in FIG. 8A are closed, the guide shaft member 54B is moved in the direction of the arrow A. , The wire 53 stretched between the reels 52 rotates, and the guide shaft member 54A moves in the direction of arrow B. When the guide shaft member 54 A moves in the direction of arrow B, the shoji 23 is in a fixed state, and therefore, the muffler 22 moves in the direction of arrow A. Accordingly, the inner shoji 21 and the middle shoji 22 move in the direction of the arrow A in the figure, and finally, as shown in FIG. 8 (C), the three shoji 21-21 overlap each other. Thus, the open state shown in FIG. 5 is obtained.

逆に、図５に示す開放状態から、内障子２１を図８の矢印Ｂの方向に摺動させると、連動部材５０が前述とは逆向きに作用して、図４に示す完全に閉じられた状態となる。このような連動部材５０により、内障子２１を摺動させるだけで、中障子２２を連動して摺動させることができ、障子２０の開閉が容易となる。 On the other hand, when the inner shoji 21 is slid in the direction of arrow B in FIG. 8 from the open state shown in FIG. 5, the interlocking member 50 acts in the opposite direction to the above and is completely closed as shown in FIG. It becomes a state. With such an interlocking member 50, the sliding door 20 can be slid in an interlocking manner only by sliding the inner sliding door 21, and the opening and closing of the sliding door 20 is facilitated.

図９は、図４のＩＸ−ＩＸ断面図である。図９に示すように、障子２０を閉じた状態で、中障子２２における外障子２３側の竪框、すなわち、中障子２２の図４中右側の召合框２２２には、見込み方向に沿って室内側に突出する突出部６１が一体的に形成されている。突出部６１には、上側に溝部６１Ａが形成されている。溝部６１Ａには、内障子２１を摺動させるための第２レール１１Ａが係合している。このため、図２に示すように、突出部６１を含む召合框２２２が２つのレール１１Ａ，１１Ｂに跨るように配置される。このように召合框２２２に突出部６１を形成して、召合框２２２を補強している。また、溝部６１Ａと内障子２１用のレール１１Ａとを係合させることにより、召合框２２２の室内外方向へのがたつきを抑えることができ、中障子２２の耐風性を向上できる。なお、内障子２１用の第２レール１１Ａは補強部となっている。 9 is a cross-sectional view taken along the line IX-IX in FIG. As shown in FIG. 9, with the shoji 20 closed, the saddle 22 on the side of the external shoji 23 in the shoji 22, that is, the summon 222 on the right side of FIG.

(３)召合框２２１，２２２の見付寸法Ｐ，Ｑが、複層ガラス２８の呑込寸法Ｒの略２倍となる寸法で、かつ４０ｍｍ以下となるようにしたので、一般的な召合框の場合に比べて小さくなるため、障子２０に対する召合框２２１，２２２の占める割合が小さくなって、室内の開放感をより一層向上できる。 (3) Since the finding dimensions P and Q of the summit bowls 221 and 222 are approximately twice the penetration dimension R of the double glazing 28 and 40 mm or less, Since it becomes smaller than the case of the combination, the ratio of the summons 221 and 222 to the shoji 20 is reduced, and the feeling of opening in the room can be further improved.

(４)外障子２３の戸先框２３２が縦枠１３Ｒ内に収納されると、戸先框２３２の見付寸法と縦枠１３Ｒの呑込寸法とが略同一であることから、外障子２３を閉じた際に戸先框２３２が縦枠１３Ｒ内に程よく収納されて隠れるようになる。このため、障子２０を閉じた状態で、室内側から室外を眺めたときに、視界を遮る框部分が小さくなるため、室内側からの開放感をより一層向上できる。 (4) When the door toe 232 of the external shoji 23 is stored in the vertical frame 13R, the finding size of the door toe 232 and the insertion size of the vertical frame 13R are substantially the same. When the door is closed, the door toe 232 is properly housed in the vertical frame 13R and hidden. For this reason, when the outside of the shoji 20 is closed and the outdoor side is viewed from the indoor side, the heel portion that blocks the field of view is reduced, so that the feeling of opening from the indoor side can be further improved.

(５)縦枠１３Ｒにおける内障子２１の摺動箇所に対応する位置に、縦枠１３Ｒの内側面を覆うとともに、その表面が外障子２３の戸先框２３２の見込方向側の面と略面一となるアタッチメント部材１３３を取り付けたので、アタッチメント部材１３３によって、縦枠１３Ｒの内側面や外障子２３の戸先框２３２における呑込部１３０側の面が殆ど隠れるため、室内側からの開放感をさらに向上できる。 (5) The inner surface of the vertical frame 13R is covered at a position corresponding to the sliding position of the inner impingement element 21 in the vertical frame 13R, and the surface thereof is substantially the same as the surface on the prospective direction side of the door toe 232 of the outer obstacle 23 Since the attachment member 133 that is the same is attached, the attachment member 133 hides almost the inner side surface of the vertical frame 13R and the surface of the door toe 232 of the door pad 232 of the shoji 23 so that it feels open from the indoor side. Can be further improved.

(６)各網戸３１，３２の竪框３６Ｒの見付寸法が外障子２３の戸先框２３２の見付寸法と略同一となるように形成するとともに、各網戸３１，３２の竪框３６Ｌの見付寸法が外障子２３の召合框２３１の見付寸法と略同一となるように形成したので、外障子２３の竪框２６と網戸３０の竪框３６の位置が、室内外方向に揃っているため、見た目がすっきりして、室内側からの開放感を向上できる。 (6) The screen 36R of the screen doors 31 and 32 is formed so that the size of the screen 36R is substantially the same as the size of the door end screen 232 of the external door 23, and the screen 36L of the screen doors 31 and 32 Since the size of the screen is substantially the same as the size of the sump 231 of the outer screen 23, the position of the screen 26 of the screen 23 and the screen 36 of the screen door 30 are aligned in the indoor and outdoor directions. Therefore, the appearance is clear and the feeling of opening from the indoor side can be improved.

For example, one vertical frame 13 (13R) is attached to the first fin portion 131 and the second fin portion 132. The member 133 is attached, and the seal material 134 is attached to the second fin portion 132 for the other vertical frame 13 (13L). For this reason, by replacing the attachment member 133 and the sealing material 134 with the vertical frame 13 on the opposite side, the frame body 10 is removed from the building 2 and replaced with different shojis with left and right hands while using the frame body 10. It is possible to easily change the left and right hand of the shoji 30.

(８)内網戸３１に突起３１Ｂを設けるとともに、外網戸３２に突起３２Ａを設けて、内網戸３１を閉じる際や外網戸３２を開く際に、これらの突起３１Ｂ，３２Ａが係合して他方の網戸３１，３２も摺動させるようにしたので、一方の網戸３１，３２を摺動させるだけで、他方の網戸３１，３２も連動させることができ、網戸３０の開閉操作を簡単に行うことができる。また、網戸３１，３２には、前記突起３１Ｂ，３２Ａの反対側面の同位置にも同様の突起３１Ａ，３２Ｂを設けたので、網戸３１，３２の左右勝手を替えた場合であっても、前記同様にこれらの網戸３１，３２の連動作用を奏することができる。 (8) The projection 31B is provided on the inner screen 31 and the projection 32A is provided on the outer screen 32. When the inner screen 31 is closed or the outer screen 32 is opened, these projections 31B and 32A are engaged with each other. Since the screen doors 31 and 32 are also slid, the other screen doors 31 and 32 can be interlocked by simply sliding the screen doors 31 and 32, and the opening and closing operation of the screen door 30 can be easily performed. Can do. Further, since the same projections 31A and 32B are provided at the same positions on the opposite side surfaces of the projections 31B and 32A on the screen doors 31 and 32, even if the left and right sides of the screen doors 31 and 32 are changed, Similarly, the interlocking action of these screen doors 31 and 32 can be achieved.

(９)中障子２２に連動部材５０を備えたので、内障子２１を閉じるように摺動させると、それに伴って中障子２２が連動して摺動するため、内障子２１を操作するだけで、簡単に障子２０の開閉を行うことができる。 (9) Since the interlock member 50 is provided with the interlocking member 50, if the sliding member 21 is slid so as to close, the sliding member 22 slides in conjunction with the sliding member 21. The shoji 20 can be easily opened and closed.
