また障子固定ピース３は、図１（ａ）に示すように、框係合部２３から室内側に離間して上方に突出する枠係合部３１を有している。枠係合部３１は、框係合部２３よりも内周側に位置しており、枠係合部３１の室内側上端部には斜め４５°の傾斜面３２を有している。框係合部２３と枠係合部３１との間には、上枠９の戸当たり片１２の外周側端部及びタイト材１４を受け入れる空間３７が設けてある。
さらに本障子固定ピース３は、枠係合部３１の下方に連続して左右両側の側方に張り出すように開き規制片３３，３３が設けてある。また、障子固定ピース３の下面の室外側端より内周側に向けて延出して手掛け部３４が設けてある。さらに、障子固定ピース３の室内側面に工具差込穴３５が室外側に向けて設けてある。 As shown in FIG. 2, the shoji fixing pieces 3 are a set of two left and right, and the left and right shoji fixing pieces 3 and 3 have the same symmetrical shape. The shoji fixing piece 3 is integrally molded with a hard resin, and has a hook-shaped stile engaging portion 23 formed on the outdoor side as shown in FIG. 1 (a). The stile engaging portion 23 has a groove 24 that engages with the outer peripheral side edge portion 19 of the found wall of the upper stile 4, and an abutting portion 25 that abuts on the bottom surface of the recess 22 of the upper stile 4. Protrusions 26a and 26b for preventing disengagement are formed in the groove 24. The groove 24 is formed with a margin with respect to the outer peripheral side edge portion 19 of the found wall of the upper stile 4. The shoji fixing piece 3 is slidably attached in the longitudinal direction of the upper stile 4 by engaging the groove 24 of the stile engaging portion 23 with the outer peripheral side edge 19 of the found wall of the upper stile 4 from above. ..
Further, as shown in FIG. 1A, the shoji fixing piece 3 has a frame engaging portion 31 which is separated from the stile engaging portion 23 toward the indoor side and projects upward. The frame engaging portion 31 is located on the inner peripheral side of the frame engaging portion 23, and has an inclined surface 32 at an angle of 45 ° at the upper end portion of the frame engaging portion 31 on the indoor side. Between the stile engaging portion 23 and the frame engaging portion 31, a space 37 for receiving the outer peripheral side end portion of the door stop piece 12 of the upper frame 9 and the tight material 14 is provided.
Further, the shoji fixing piece 3 is provided with opening restricting pieces 33, 33 so as to continuously project below the frame engaging portion 31 on both the left and right sides. Further, a handle portion 34 is provided so as to extend toward the inner peripheral side from the outdoor end of the lower surface of the shoji fixing piece 3. Further, a tool insertion hole 35 is provided on the indoor side surface of the shoji fixing piece 3 so as to face the outdoor side.

本障子固定ピース３は、框係合部２３の溝２４が上框４の見付壁の外周側縁部１９に対して余裕を持って形成してあることで、図３に示すように、障子２を開いた状態で框係合部２３を上框４の見付壁の外周側縁部１９に係合して取付けると、上框４の見付壁の外周側縁部１９を支点として枠係合部３１が内外周方向に回動し得るようになっている。 As shown in FIG. 3, the shoji fixing piece 3 has a groove 24 of the stile engaging portion 23 formed with a margin with respect to the outer peripheral side edge portion 19 of the found wall of the upper stile 4. When the stile engaging portion 23 is engaged with and attached to the outer peripheral side edge 19 of the found wall of the upper stile 4 with the shoji 2 open, the outer peripheral side edge 19 of the found wall of the upper stile 4 is used as a fulcrum. The frame engaging portion 31 can rotate in the inner and outer peripheral directions.

次に、障子２を閉鎖し固定する際の手順を説明する。まず、図５（ａ）に示すように、上框４の左右２か所に障子固定ピース３，３を、上框４の見付壁の外周側縁部１９に障子固定ピース３，３の框係合部２３の溝２４を上方から係合させて取付ける。このとき、開き規制片３３の先端が縦枠６の戸当たり片７の内周側端より内周側に位置するようにしておく。
次に、図４（ａ）に示すように、障子固定ピース３の手掛け部３４に手を掛けて上框４を内周側から掴んで障子２を閉める。手掛け部３４に手を掛けることで、枠係合部３１が内周側に移動した状態になっている。
障子２を閉めてゆくと、図４（ｂ）に示すように、傾斜面３２が上枠９の戸当たり片１２の先端と擦れながら、枠係合部３１が上枠９の戸当たり片１２の先端部を乗り越える。
さらに障子２が閉まると、図４（ｃ）に示すように、上枠４の戸当たり片１２の見付面（リップ溝１３及びタイト材１４が設けてある部分）に押されて障子固定ピース３が上框４の見付壁の外周側縁部１９を支点として外周側に向けて回動する。
それに伴い、図４（ｄ）に示すように、障子固定ピース３の枠係合部３１が上枠９の戸当たり片１２の障子２と反対側の面に引っ掛かり、これにより障子２が開かないように枠１に固定される。枠係合部３１の戸当たり片１２との掛かり代Ｙは、５～１０ｍｍとしてある。枠係合部３１は変形しないように十分な強度を持たせてあり、上枠９の戸当たり片１２との掛かり代Ｙも十分大きく取ってあるため、ダンパーによる強い付勢力が作用しても枠係合部３１が戸当たり片１２から外れて障子２が開くことはない。なお、上述した障子２を閉める操作は、枠１の室内側面を床に置いて寝かせた状態で行うことができる。
その後、図５（ｂ）に示すように、左右の障子固定ピース３，３を外周側にスライドさせ、図５（ｃ）に示すように、障子固定ピース３，３の開き規制片３３を縦枠６の戸当たり片７の室内側に対向させる。これにより、万が一、枠係合部３１が上枠９の戸当たり片１２から外れても、開き規制片３３が縦枠６の戸当たり片７に引っ掛かることで、障子２が開くのを防止できる。 Next, the procedure for closing and fixing the shoji 2 will be described. First, as shown in FIG. 5A, the shoji fixing pieces 3 and 3 are placed on the left and right sides of the upper stile 4, and the shoji fixing pieces 3 and 3 are placed on the outer peripheral side edge 19 of the found wall of the upper stile 4. The groove 24 of the stile engaging portion 23 is engaged and attached from above. At this time, the tip of the opening restricting piece 33 is set to be located on the inner peripheral side of the inner peripheral side end of the door stop piece 7 of the vertical frame 6.
Next, as shown in FIG. 4A, the shoji 2 is closed by holding the upper stile 4 from the inner peripheral side by putting a hand on the handle portion 34 of the shoji fixing piece 3. By putting a hand on the handle portion 34, the frame engaging portion 31 is in a state of being moved to the inner peripheral side.
As the shoji 2 is closed, as shown in FIG. 4 (b), the frame engaging portion 31 rubs against the tip of the door stop piece 12 of the upper frame 9 while the inclined surface 32 rubs against the door stop piece 12 of the upper frame 9. Get over the tip of the shoji.
When the shoji 2 is further closed, as shown in FIG. 4 (c), the shoji fixing piece is pushed by the found surface (the portion where the lip groove 13 and the tight material 14 are provided) of the door stop piece 12 of the upper frame 4. 3 rotates toward the outer peripheral side with the outer peripheral side edge 19 of the found wall of the upper stile 4 as a fulcrum.
Along with this, as shown in FIG. 4D, the frame engaging portion 31 of the shoji fixing piece 3 is caught on the surface of the upper frame 9 of the door stop piece 12 on the side opposite to the shoji 2 so that the shoji 2 does not open. It is fixed to the frame 1 as described above. The hooking allowance Y of the frame engaging portion 31 with the door stop piece 12 is set to 5 to 10 mm. The frame engaging portion 31 is provided with sufficient strength so as not to be deformed, and the hooking allowance Y with the door stop piece 12 of the upper frame 9 is sufficiently large, so that even if a strong urging force by the damper acts. The frame engaging portion 31 does not come off from the door stop piece 12 and the shoji 2 does not open. The operation of closing the shoji 2 described above can be performed with the indoor side surface of the frame 1 placed on the floor and laid down.
After that, as shown in FIG. 5 (b), the left and right shoji fixing pieces 3 and 3 are slid to the outer peripheral side, and as shown in FIG. 5 (c), the opening restricting piece 33 of the shoji fixing pieces 3 and 3 is vertically inserted. The door stop piece 7 of the frame 6 faces the indoor side. As a result, even if the frame engaging portion 31 is disengaged from the door stop piece 12 of the upper frame 9, the opening restricting piece 33 is caught by the door stop piece 7 of the vertical frame 6 to prevent the shoji 2 from opening. ..

施工現場において障子２を開く際には、まず左右の障子固定ピース３，３を開き規制片３３が縦枠６の戸当たり片７から外れる位置まで内周側にスライドさせる。
次に、図６（ａ）に示すように、障子固定ピース３の工具差込穴３５に室内側からドライバー等の工具３６を差し入れ、図６（ｂ）に示すように、工具３６で内周側に力を加えることで障子固定ピース３の枠係合部３１を内周側に回動させる。
これにより、図６（ｃ）に示すように、枠係合部３１が上枠９の戸当たり片１２から外れて障子２が開く。その後、障子固定ピース３，３を取り外す。 When opening the shoji 2 at the construction site, first, the left and right shoji fixing pieces 3 and 3 are opened and the regulation piece 33 is slid inward to the position where it comes off from the door stop piece 7 of the vertical frame 6.
Next, as shown in FIG. 6A, a tool 36 such as a screwdriver is inserted into the tool insertion hole 35 of the shoji fixing piece 3 from the indoor side, and as shown in FIG. 6B, the inner circumference of the tool 36 is used. By applying a force to the side, the frame engaging portion 31 of the shoji fixing piece 3 is rotated to the inner peripheral side.
As a result, as shown in FIG. 6 (c), the frame engaging portion 31 is disengaged from the door stop piece 12 of the upper frame 9, and the shoji 2 is opened. After that, the shoji fixing pieces 3 and 3 are removed.

図７は本発明の障子固定ピース３の他の実施形態を示している。本障子固定ピース３は、枠係合部３１の内周側の左右両側位置に、室外側に向けてＵ字形のバネ片３８が設けてある。本障子固定ピース３は、上框４の見付壁の外周側縁部１９に框係合部２３の溝２４を係合させて取付けると、バネ片３８の室外側端部が上框４の室内側面に当接してバネ片３８が弾性変形し、これにより図中の矢印３９に示すように、障子固定ピース３は枠係合部３１が上框４の見付壁の外周側縁部１９を支点として外周側に向けて回動する方向に付勢されている。
本障子固定ピース３は、先の実施形態と同様に、框係合部２３の溝２４が上框４の見付壁の外周側縁部１９に対して余裕を持って形成してあって、障子２を開いた状態では、障子固定ピース３は上框４の見付壁の外周側縁部１９を支点として枠係合部３１が内外周方向に回動し得るようになっているが、上記のようにバネ片３８による付勢力が働くことで、当接部２５が上框４の凹部２２底面に当接した姿勢に保持され、障子固定ピース３が上框４から外れにくくなっている。
また本障子固定ピース３は、工具差込穴３５が室外側に向かって外周側に傾斜して設けてある。 FIG. 7 shows another embodiment of the shoji fixing piece 3 of the present invention. The shoji fixing piece 3 is provided with U-shaped spring pieces 38 facing the outdoor side at positions on both the left and right sides of the inner peripheral side of the frame engaging portion 31. When the shoji fixing piece 3 is attached by engaging the groove 24 of the stile engaging portion 23 with the outer peripheral side edge portion 19 of the found wall of the upper stile 4, the outdoor end of the spring piece 38 becomes the upper stile 4. The spring piece 38 is elastically deformed in contact with the side surface of the room, and as a result, as shown by the arrow 39 in the drawing, the frame engaging portion 31 of the shoji fixing piece 3 is the outer peripheral side edge portion 19 of the found wall of the upper stile 4. Is urged in the direction of rotation toward the outer peripheral side with the fulcrum as a fulcrum.
In the shoji fixing piece 3, the groove 24 of the stile engaging portion 23 is formed with a margin with respect to the outer peripheral side edge portion 19 of the found wall of the upper stile 4, as in the previous embodiment. In the state where the shoji 2 is open, the shoji fixing piece 3 allows the frame engaging portion 31 to rotate in the inner and outer peripheral directions with the outer peripheral side edge portion 19 of the found wall of the upper stile 4 as a fulcrum. As described above, the urging force of the spring piece 38 keeps the contact portion 25 in contact with the bottom surface of the recess 22 of the upper stile 4, making it difficult for the shoji fixing piece 3 to come off the upper stile 4. ..
Further, the shoji fixing piece 3 is provided with a tool insertion hole 35 inclined toward the outer peripheral side toward the outdoor side.

図８は、上記の障子固定ピース３により枠１に固定した障子２を開く際の手順を示している。障子２を開く際には、図８（ａ）に示すように、障子固定ピース３の工具差込穴３５に室内側からドライバー等の工具３６を差し入れ、図８（ｂ）に示すように、工具３６で内周側に力を加えることで障子固定ピース３の枠係合部３１を内周側に回動させ、枠係合部３１を上枠９の戸当たり片１２から外す。その際、工具差込穴３５が室外側に向かって外周側に傾斜して設けてあることで、高所にある排煙窓であっても工具差込穴３５に工具３６を差し込みやすく、工具３６の先端で枠１を傷つけたり、工具３６が工具差込穴３５から不意に外れたりしたときに手が枠１に当たって怪我をしたりするのを防ぐことができる。
障子固定ピース３の枠係合部３１が上枠９の戸当たり片１２から外れると、図８（ｃ）に示すように、障子２はダンパーの力で勢いよく開くが、バネ片３８の付勢力により枠係合部３１が外周向きに回動して、框係合部２３の溝２４内に設けた外れ止め用の突起２６ａ，２６ｂが上框４の見付壁の外周側縁部１９にしっかり掛かるため、障子２が開く際の反動で障子固定ピース３が外れて落下するのを防ぐことができる。 FIG. 8 shows a procedure for opening the shoji 2 fixed to the frame 1 by the shoji fixing piece 3. When opening the shoji 2, as shown in FIG. 8 (a), a tool 36 such as a screwdriver is inserted into the tool insertion hole 35 of the shoji fixing piece 3 from the indoor side, and as shown in FIG. 8 (b). By applying a force to the inner peripheral side with the tool 36, the frame engaging portion 31 of the shoji fixing piece 3 is rotated toward the inner peripheral side, and the frame engaging portion 31 is removed from the door stop piece 12 of the upper frame 9. At that time, since the tool insertion hole 35 is provided so as to be inclined toward the outer peripheral side toward the outdoor side, it is easy to insert the tool 36 into the tool insertion hole 35 even in a smoke exhaust window at a high place, and the tool can be easily inserted. It is possible to prevent the frame 1 from being damaged by the tip of the 36, or the hand from hitting the frame 1 and being injured when the tool 36 is unexpectedly removed from the tool insertion hole 35.
When the frame engaging portion 31 of the shoji fixing piece 3 is disengaged from the door stop piece 12 of the upper frame 9, the shoji 2 is vigorously opened by the force of the damper as shown in FIG. 8 (c), but the spring piece 38 is attached. The frame engaging portion 31 is rotated toward the outer periphery by the force, and the protrusions 26a and 26b for preventing disengagement provided in the groove 24 of the stile engaging portion 23 are the outer peripheral side edge portion 19 of the found wall of the upper stile 4. It is possible to prevent the shoji fixing piece 3 from coming off and falling due to the reaction when the shoji 2 is opened.

以上に述べたように本障子固定ピース３は、框係合部２３と枠係合部３１とを備え、枠係合部３１は、框係合部２３と見込み方向に離間して框係合部２３よりも内周側に位置しており、障子２を開いた状態で框係合部２３を框（上框）４の見付壁の外周側縁部１９に係合して取付けると、框４の見付壁の外周側縁部１９を支点として枠係合部３１が内外周方向に回動自在であり、障子２を閉鎖すると枠係合部３１が枠（上枠）９の戸当たり片１２の先端部を乗り越えるとともに、枠９の戸当たり片１２の見付面で押されることで外周側に回動して、枠９の戸当たり片１２の障子２と反対側の面に引っ掛かることで、障子２を閉鎖するだけで障子２を閉鎖状態に確実に保持できる。
また本障子固定ピース３は、框内周側に延出する手掛け部３４を有し、手掛け部３４は、障子２を閉鎖する際に框４の内周側から手を掛けるものなので、障子２を閉める際に手掛け部３４に手を掛けることで枠係合部３１を内周側に回動した状態に保持し、障子２をスムーズに閉鎖できる。
また本障子固定ピース３は、工具差込穴３５を有し、工具差込穴３５に工具３６を差し込んで力を加えることで枠係合部３１が内周側に回動して枠９の戸当たり片１２から外れるので、障子２を開ける際の作業性も良い。工具差込穴３５が室外側に向かって外周側に傾斜して設けてあると、障子２を開ける際の作業性が一層向上する。
さらに本障子固定ピース３は、框４の長手方向にスライド自在であり、外側にスライドしたときに縦枠６の戸当たり片７の障子２と反対側の面に対向する開き規制片３３を有するので、万が一、枠係合部３１が外れても開き規制片３３が縦枠６の戸当たり片７に引っ掛かることで障子２が開くのを防止できる。
障子固定ピース３に、上框４の室内側面に押接するバネ片３８が設けてあると、障子２が開いたときの反動で障子固定ピース３が外れて落下するのを防止できる。
本障子固定ピース３を使用することで、粘着テープを貼ったり剥がしたりする手間が要らなくなり、粘着テープの跡が残ることもない。障子固定ピース３は、繰り返し使用することができ、経済的である。 As described above, the shoji fixing piece 3 includes a stile engaging portion 23 and a frame engaging portion 31, and the frame engaging portion 31 is separated from the stile engaging portion 23 in a prospective direction to engage with the stile. It is located on the inner peripheral side of the portion 23, and when the stile engaging portion 23 is engaged with the outer peripheral side edge portion 19 of the found wall of the stile (upper stile) 4 with the shoji 2 open, it is attached. The frame engaging portion 31 is rotatable in the inner and outer peripheral directions with the outer peripheral side edge portion 19 of the found wall of the stile 4 as a fulcrum, and when the shoji 2 is closed, the frame engaging portion 31 becomes the door of the frame (upper frame) 9. While overcoming the tip of the hit piece 12, it is pushed by the found surface of the door stop piece 12 of the frame 9 to rotate to the outer peripheral side, and to the surface of the frame 9 on the opposite side of the door stop piece 12 to the shoji 2. By being caught, the shoji 2 can be reliably held in the closed state only by closing the shoji 2.
Further, the sash fixing piece 3 has a handle portion 34 extending to the inner peripheral side of the stile, and the sash portion 34 handles the sash 2 from the inner peripheral side of the stile 4 when closing the sash 2. By putting a hand on the handle portion 34 when closing the shoji, the frame engaging portion 31 can be held in a state of being rotated inward, and the shoji 2 can be closed smoothly.
Further, the shoji fixing piece 3 has a tool insertion hole 35, and when a tool 36 is inserted into the tool insertion hole 35 and a force is applied, the frame engaging portion 31 rotates toward the inner peripheral side of the frame 9. Since it comes off from the door-to-door piece 12, workability when opening the shoji 2 is also good. If the tool insertion hole 35 is provided so as to be inclined toward the outer peripheral side toward the outdoor side, the workability when opening the shoji 2 is further improved.
Further, the shoji fixing piece 3 is slidable in the longitudinal direction of the stile 4, and has an opening restricting piece 33 facing the surface opposite to the shoji 2 of the door stop piece 7 of the vertical frame 6 when sliding outward. Therefore, even if the frame engaging portion 31 is disengaged, the opening restricting piece 33 can be prevented from being opened by the door-stopping piece 7 of the vertical frame 6.
If the shoji fixing piece 3 is provided with a spring piece 38 that presses against the indoor side surface of the upper stile 4, it is possible to prevent the shoji fixing piece 3 from coming off and falling due to the reaction when the shoji 2 is opened.
By using the shoji fixing piece 3, it is not necessary to attach or remove the adhesive tape, and no trace of the adhesive tape remains. The shoji fixing piece 3 can be used repeatedly and is economical.
