以下、本発明の実施の形態を図面に基づいて説明する。図１，２は、本発明の改装サッシの第１実施形態を示している。本改装サッシは、引き違い窓に適用したものであって、既設枠４が取り付いた開口部２６に室外側から納めて躯体５に固定したリフォーム枠３と、リフォーム枠３の室内側に取付けた樹脂額縁２７と、リフォーム枠３の上下の横枠に沿って摺動可能に納めた外障子２８と内障子２９と網戸３０とを備えている。
BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. Figures 1 and 2 show a first embodiment of the retrofit sash of the invention. This refurbished sash is applied to a double sliding window, and includes a remodeling frame 3 fixed to a building frame 5 by being housed from the outdoor side in an opening 26 to which an existing frame 4 is attached, a resin frame 27 attached to the interior side of the remodeling frame 3, an outer shoji 28, an inner shoji 29 and a screen door 30 slidably housed along the upper and lower lateral frames of the remodeling frame 3.
既設枠４は、引違い窓用のアングル無しのサッシ枠であり、図１，２に示すように、アルミ形材よりなる上枠３１と下枠３２と左右の縦枠３３，３３とを枠組みして構成され、いわゆる半外付けの状態で躯体５に取付けられている。既設枠４の室内側には、木製の既設額縁３４が設けられている。
The existing frame 4 is a sash frame without angles for a double sliding window, and as shown in FIGS. An existing wooden frame 34 is provided on the indoor side of the existing frame 4 .
リフォーム枠３は、図１～３に示すように、新設枠１と、新設枠１の周囲を囲む外周枠２とで構成されている。
新設枠１は、アルミ形材よりなる上枠３５と下枠３６と左右の縦枠３７，３７とを四周枠組みして構成してある。上枠３５と下枠３６は、見込方向の中間部に断熱ブリッジ３８を設けて断熱してある。また新設枠１は、室内側には樹脂アングル３９を設け、室内側の結露を防止してある。
本新設枠１は、図７に示すように、一般的な半外付けのサッシ枠の躯体固定用のフィン４０を折取ったものである。
The renovation frame 3 is composed of a new frame 1 and an outer frame 2 surrounding the new frame 1, as shown in FIGS.
The newly installed frame 1 is constructed by forming an upper frame 35, a lower frame 36, and left and right vertical frames 37, 37 made of an aluminum shape member. The upper frame 35 and the lower frame 36 are insulated by providing a heat insulating bridge 38 at an intermediate portion in the viewing direction. Also, the new frame 1 is provided with a resin angle 39 on the indoor side to prevent dew condensation on the indoor side.
The new frame 1, as shown in FIG. 7, is obtained by breaking off a fin 40 for fixing the skeleton of a general semi-external sash frame.
新設枠１は、図８に示すように、左右の縦枠３７，３７の外周側面に当接して金属製の補強板２５が設けてある。補強板２５は、縦枠３７の外周側面の上部と下部の２箇所に上枠３５と下枠３６の側方の位置に配置され、外周側から補強板２５と縦枠３７に貫通したネジ４１を上枠３５と下枠３６のタッピングホール４２に螺入することで、補強板２５と縦枠３７を上枠３５及び下枠３６に共締めしてある。上枠３５及び下枠３６の長手方向の端面と縦枠３７の内周側面との間には、シート状のシーラー４３を介在させてある。補強板２５は、室外側の端部を縦枠３７の外周側に向けて突出する片４４に突き当ててある。
As shown in FIG. 8, the new frame 1 is provided with metal reinforcing plates 25 in contact with the outer peripheral side surfaces of the left and right vertical frames 37 , 37 . The reinforcing plate 25 is arranged at two positions on the upper part and the lower part of the outer peripheral side of the vertical frame 37 at the side positions of the upper frame 35 and the lower frame 36, and the reinforcing plate 25 and the vertical frame 37 are fastened together to the upper frame 35 and the lower frame 36 by screwing the screws 41 penetrating the reinforcing plate 25 and the vertical frame 37 from the outer peripheral side into the tapping holes 42 of the upper frame 35 and the lower frame 36. A sheet-like sealer 43 is interposed between the longitudinal end surfaces of the upper frame 35 and the lower frame 36 and the inner peripheral side surface of the vertical frame 37 . The reinforcing plate 25 abuts a piece 44 protruding toward the outer peripheral side of the vertical frame 37 at its outdoor-side end.
このように縦枠３７の外周側に補強板２５を設け、補強板２５と縦枠３７を横枠（上枠、下枠）３５，３６にネジ４１で共締めしたことで、障子２８，２９を勢いよく閉めたときなどに縦枠３７が外周側に広がるように変形するのを防止し、水密性を維持することができる。補強板２５の室外側の端部を縦枠３７の外周側に向けて突出する片４４に突き当ててあることで、縦枠３７の変形を防ぐ効果が高められる。なお、このように新設枠１の縦枠３７の外周側に補強板２５が設けてある点は、後述する第２，４，５実施形態についても同様である。
By providing the reinforcing plate 25 on the outer peripheral side of the vertical frame 37 and fastening the reinforcing plate 25 and the vertical frame 37 to the horizontal frames (upper and lower frames) 35 and 36 with the screws 41, the vertical frame 37 is prevented from being deformed so as to spread to the outer peripheral side when the shojis 28 and 29 are vigorously closed, and watertightness can be maintained. The effect of preventing deformation of the vertical frame 37 is enhanced by abutting the end portion of the reinforcement plate 25 on the outdoor side against the piece 44 projecting toward the outer peripheral side of the vertical frame 37 . It should be noted that the fact that the reinforcing plate 25 is provided on the outer peripheral side of the vertical frame 37 of the new frame 1 is the same for the second, fourth and fifth embodiments, which will be described later.
外周枠２は、図１～４に示すように、アルミ形材よりなる上枠４５と下枠４６と左右の縦枠４７，４７を四周枠組みして構成してある。より詳細には、上枠４５と下枠４６の長手方向の端面をシール材５６（図２，３参照）を介して縦枠４７，４７の内周側面に突き当て、側方から縦枠に挿通したねじ１０３（図３，４参照）を上下枠４５，４６のタッピングホール４８に螺入することで枠組みしてある。
上枠４５と下枠４６と左右の縦枠４７は、図１，２に示すように、それぞれ見込方向に延びる主部材４９と、主部材４９の室外側端部に着脱自在に取付けられ、外周側に向けて延びるカバー片５０の２部材で構成されている。各カバー片５０は、既設枠の室外側壁の室外側に重合している。主部材４９は、新設枠１及び既設枠４の室内側壁よりも室内側に延出した延出部５１が設けてあり、延出部５１にはリフォーム枠３を躯体５に固定するためのねじ５２が挿通される孔５３が設けてある。また主部材４９は、室外側と室内側の２箇所に位置決め部５４が設けてあり、各位置決め部５４を新設枠１の上枠３５と下枠３６と縦枠３７に外周側から係合させることで、外周枠２の上枠４５と下枠４６と縦枠４７を見込方向に位置決めできるとともに、新設枠１と外周枠２を一体化できるようになっている。カバー片５０は、室内側面に内外周方向に間隔をおいて折取り自在部５５が複数設けてあり、既設枠４の形状等に応じて折取り自在部５５で適宜折取ることで、見付寸法を変更できる。
As shown in FIGS. 1 to 4, the outer peripheral frame 2 is composed of an upper frame 45, a lower frame 46, and left and right vertical frames 47, 47 made of an aluminum profile. More specifically, the longitudinal end faces of the upper frame 45 and the lower frame 46 are abutted against the inner peripheral side surfaces of the vertical frames 47, 47 via the sealing material 56 (see FIGS. 2 and 3), and the vertical frames are inserted from the side and the screws 103 (see FIGS. 3 and 4) are screwed into the tapping holes 48 of the upper and lower frames 45, 46 to form a framework.
As shown in FIGS. 1 and 2, the upper frame 45, the lower frame 46, and the left and right vertical frames 47 are composed of two members: a main member 49 extending in the projection direction, and a cover piece 50 detachably attached to the outdoor end of the main member 49 and extending toward the outer peripheral side. Each cover piece 50 overlaps the outdoor side of the outdoor side wall of the existing frame. The main member 49 is provided with an extension part 51 extending into the room from the indoor side wall of the new frame 1 and the existing frame 4, and the extension part 51 is provided with a hole 53 through which a screw 52 for fixing the reform frame 3 to the skeleton 5 is inserted. The main member 49 is provided with positioning portions 54 at two locations, one on the outdoor side and the other on the indoor side. By engaging the positioning portions 54 with the upper frame 35, the lower frame 36, and the vertical frame 37 of the new frame 1 from the outer peripheral side, the upper frame 45, the lower frame 46, and the vertical frame 47 of the outer peripheral frame 2 can be positioned in the line of sight, and the new frame 1 and the outer peripheral frame 2 can be integrated. The cover piece 50 is provided with a plurality of breakable portions 55 spaced apart in the inner and outer peripheral directions on the inner and outer side surfaces of the room.
図１，２に示すように、新設枠１の外周側面と外周枠２の内周側面との隙間には、気密材５７ａ，５７ｂ，５７ｃ，５７ｄが四周連続して設けてある。この気密材５７ａ，５７ｂ，５７ｃ，５７ｄは、新設枠１のフィン４０を折取った位置に設けてある。
外周枠２の縦枠４７には、横枠（上枠、下枠）４５，４６の端面との接合部にシール材５６が設けてあり、外周枠２の横枠４５，４６に沿って延びる横気密材５７ａ，５７ｂと外周枠２の縦枠４７，４７に沿って延びる縦気密材５７ｃ，５７ｄの長手方向端部がシール材５６に当接しており、シール材５６を介して横気密材５７ａ，５７ｂと縦気密材５７ｃ，５７ｄとが連続している。これにより、新設枠１と外周枠２の間の隙間から雨水が室内に浸入するのを防止している。
また、外周枠２の上枠４５のカバー片５０と既設枠４の上枠３１の室外側壁との隙間、外周枠２の縦枠４７，４７のカバー片５０，５０と既設枠４の縦枠３３，３３の室外側壁との隙間にも、気密材５８ａ，５８ｂが連続して設けてある。これにより、リフォーム枠３と既設枠４との隙間に雨水が浸入するのを防いでいる。
As shown in FIGS. 1 and 2, airtight members 57a, 57b, 57c, and 57d are continuously provided in the gap between the outer peripheral side surface of the new frame 1 and the inner peripheral side surface of the outer peripheral frame 2. As shown in FIGS. The airtight members 57a, 57b, 57c, and 57d are provided at positions where the fins 40 of the new frame 1 are broken off.
The vertical frame 47 of the outer peripheral frame 2 is provided with a seal member 56 at the joint portion with the end faces of the horizontal frames (upper frame, lower frame) 45, 46. The longitudinal ends of the horizontal airtight members 57a, 57b extending along the horizontal frames 45, 46 of the outer peripheral frame 2 and the vertical airtight members 57c, 57d extending along the vertical frames 47, 47 of the outer peripheral frame 2 are in contact with the sealing member 56. 7a, 57b and vertical airtight members 57c, 57d are continuous. This prevents rainwater from entering the room through the gap between the new frame 1 and the outer frame 2. - 特許庁
Airtight materials 58a and 58b are continuously provided in the gap between the cover piece 50 of the upper frame 45 of the outer peripheral frame 2 and the outdoor side wall of the upper frame 31 of the existing frame 4, and the gap between the cover pieces 50 and 50 of the vertical frames 47 and 47 of the outer peripheral frame 2 and the outdoor side wall of the vertical frames 33 and 33 of the existing frame 4. This prevents rainwater from entering the gap between the reforming frame 3 and the existing frame 4. - 特許庁
図１，２に示すように、既設枠４の室内側の既設額縁３４の内周側には、リフォーム枠３を躯体５に固定するためのベースとなる取付補助材６が四周に設けてある。取付補助材６は、アルミ形材で形成したものであって、室外側及び室内側の見付壁５９ａ，５９ｂと見込壁６０とで断面コ字型に形成されている。室外側及び室内側の見付壁５９ａ，５９ｂには、内外周方向に間隔をおいて折取り自在部６１が複数設けてある。取付補助材６は、折取り自在部６１で見付壁５９ａ，５９ｂを適宜折取って見付寸法を調整し、見込壁６０の内周側面の位置が既設枠４の内周側に最も飛び出した部分６２と内外周方向のほぼ同じ位置になるようにしている。なお、図１，２では、見付壁５９ａ，５９ｂが既設額縁３４と干渉しているように見えるが、実際には折取り自在部６１で折取って既設額縁３４と干渉する部分は無くなる。
各取付補助材６は、室外側の見付壁５９ａを既設枠４の室内側壁に当接して配置され、これにより取付補助材６の室内側端の位置が既設枠４の室外側端から所定の寸法Ａ（具体的には１１０ｍｍ）となるように取付補助材６を見込方向に位置決めしている。取付補助材６は、見込壁６０に内周側から挿通したねじ６３で躯体５に固定してある。
As shown in FIGS. 1 and 2, on the inner peripheral side of the existing frame 34 on the indoor side of the existing frame 4, mounting aids 6 serving as a base for fixing the remodeling frame 3 to the frame 5 are provided around the four circumferences. The mounting support member 6 is made of an aluminum profile, and is formed into a U-shaped cross section by the projection walls 59a and 59b on the outside and inside of the room and the projection wall 60. As shown in FIG. A plurality of breakable portions 61 are provided at intervals in the inner and outer peripheral directions on the outdoor and indoor side walls 59a and 59b. The mounting auxiliary member 6 appropriately breaks off the attachment walls 59a and 59b with a breakable part 61 to adjust the attachment size so that the position of the inner peripheral side surface of the attachment wall 60 is almost the same position in the inner and outer peripheral directions as the part 62 protruding most toward the inner peripheral side of the existing frame 4. - 特許庁1 and 2, it appears that the attachment walls 59a and 59b are interfering with the existing frame 34, but in reality there is no portion that interferes with the existing frame 34 by being broken off by the breakable portion 61. FIG.
Each of the auxiliary mounting members 6 is arranged with the outdoor side wall 59a in contact with the indoor side wall of the existing frame 4, whereby the mounting auxiliary members 6 are positioned in the viewing direction so that the position of the indoor side end of the mounting auxiliary member 6 is a predetermined dimension A (specifically, 110 mm) from the outdoor side end of the existing frame 4. The mounting support member 6 is fixed to the frame 5 with a screw 63 inserted through the projection wall 60 from the inner peripheral side.
リフォーム枠３は、図１，２に示すように、外周枠２の室内側端６４が取付補助材６の室内側端と一致するように見込方向に位置決めし、取付補助材６の位置で延出部５１に内周側から挿入したねじ５２で躯体５に固定されている。外周枠２と取付補助材６との間には、必要に応じて飼い木６５を介在させる。
本改装サッシは、このように取付補助材６を既設枠４の室内側壁に当接した状態で取付けた上で、リフォーム枠３（の外周枠２）の室内側端６４が取付補助材６の室内側端と一致するようにリフォーム枠３を見込方向に位置決めすることで、リフォーム枠３が自然に見込方向の適正な位置に配置され、予めリフォーム枠３のカバー片５０と既設枠４の室外側壁の一方に設けておいた気密材５８ａ，５８ｂが他方に密着し、リフォーム枠３と既設枠４の間が室外側で止水される。
As shown in FIGS. 1 and 2, the reforming frame 3 is positioned in the prospective direction so that the indoor end 64 of the outer peripheral frame 2 coincides with the indoor end of the mounting auxiliary member 6, and is fixed to the frame 5 by a screw 52 inserted from the inner peripheral side into the extending portion 51 at the position of the mounting auxiliary member 6. Between the outer peripheral frame 2 and the mounting support member 6, a pet tree 65 is interposed as required.
In this refurbished sash, the auxiliary mounting member 6 is attached to the interior side wall of the existing frame 4 in this way, and the remodeling frame 3 (the outer peripheral frame 2 thereof) is positioned in the viewing direction so that the interior side end 64 of the remodeling frame 3 (the outer peripheral frame 2) coincides with the interior side end of the mounting support member 6. As a result, the remodeling frame 3 is naturally arranged at an appropriate position in the viewing direction, and airtight members 58a and 58 are provided in advance on one of the cover piece 50 of the remodeling frame 3 and the exterior wall of the existing frame 4. b is in close contact with the other, and water is stopped between the reforming frame 3 and the existing frame 4 on the outdoor side.
さらに本改装サッシは、図１，２に示すように、既設枠４と取付補助材６に跨って既設枠側防水テープ７が取付けてあり、取付補助材６の見込壁６０と室内側の見付壁５９ｂに跨ってねじ隠し用防水テープ６６が取付けてあり、リフォーム枠３と取付補助材６に跨ってリフォーム枠側防水テープ８が設けてある。ねじ隠し用防水テープ６６は、取付補助材６を躯体５に取付けているねじ６３を隠しており、リフォーム枠側防水テープ８は、リフォーム枠３を躯体５に取付けているねじ５２を隠している。各防水テープ７，８，６６は、市販されている適当な幅の防水テープを使用し、既設枠４とリフォーム枠３の周方向に沿って連続して貼着して取付けられる。
1 and 2, the existing frame side waterproof tape 7 is attached across the existing frame 4 and the mounting auxiliary material 6, the screw concealing waterproof tape 66 is attached across the projection wall 60 of the mounting auxiliary material 6 and the interior side wall 59b, and the reformed frame side waterproof tape 8 is provided across the reformed frame 3 and the mounting auxiliary material 6. The screw hiding waterproof tape 66 hides the screw 63 for attaching the mounting auxiliary material 6 to the frame 5, and the remodeling frame side waterproof tape 8 hides the screw 52 for attaching the remodeling frame 3 to the frame 5. - 特許庁The waterproof tapes 7, 8 and 66 are commercially available waterproof tapes having appropriate widths, and are attached continuously along the circumferential direction of the existing frame 4 and the reformed frame 3. As shown in FIG.
このように本改装サッシは、既設枠４と取付補助材６に跨って取付けた既設枠側防水テープ７と、取付補助材６とリフォーム枠３に跨って取付けたリフォーム枠側防水テープ８を有することで、万が一、リフォーム枠３と既設枠４の間に室外側から雨水が浸入しても、室内側まで雨水が浸入するのを防ぐことができる。開口部２６の周縁部に取付補助材６を設け、取付補助材６に防水テープ７，８を貼着することで、平滑な防水テープ７，８の貼着面を確保でき、防水テープ７，８をきれいに貼ることができるため、止水性が高い。また、一枚の防水テープを既設枠４とリフォーム枠３に跨って貼るよりも、既設枠側防水テープ７とリフォーム枠側防水テープ８に分けて貼る方が、作業性が良い。さらに、ねじ隠し用防水テープ６６により取付補助材６を躯体５に取付けているねじ６３を隠してあるので、ねじ６３の孔から躯体５に雨水が浸入するのを防ぐことができる。
In this way, the refurbished sash has the existing frame side waterproof tape 7 attached across the existing frame 4 and the mounting auxiliary material 6, and the remodeling frame side waterproof tape 8 attached across the mounting auxiliary material 6 and the remodeling frame 3, so that even if rainwater enters between the remodeling frame 3 and the existing frame 4 from the outdoor side, rainwater can be prevented from entering the room. A mounting auxiliary member 6 is provided at the peripheral edge of the opening 26, and the waterproof tapes 7, 8 are adhered to the mounting auxiliary member 6, whereby a smooth adhered surface of the waterproof tapes 7, 8 can be secured, and the waterproof tapes 7, 8 can be neatly adhered, resulting in high waterproofing. Further, rather than sticking a single waterproof tape over the existing frame 4 and the reformed frame 3, it is better to separate the waterproof tape 7 on the existing frame side and the waterproof tape 8 on the reformed frame side for better workability. Furthermore, since the screws 63 that attach the mounting aid 6 to the frame 5 are hidden by the waterproof tape 66 for screw hiding, rainwater can be prevented from entering the frame 5 through the holes of the screws 63 .
図１，２，４に示すように、リフォーム枠３の縦枠６７と上枠６８の外周側面には、金属製の板よりなる補強材２４が枠６７，６８の長手方向に間隔をおいて複数（図４のものは３つ）設けてある。補強材２４は、リフォーム枠３の見込方向のほぼ全幅にわたって設けてあり、外周側からねじ６９で縦枠６７及び上枠６８にそれぞれねじ止めして取付けてある。補強材２４の室内側端部には、リフォーム枠３の孔５３の位置に合わせてリフォーム枠３を躯体５に固定するためのねじ５２が挿通される孔７０が設けてある。そして、リフォーム枠３と補強材２４を室内側でねじ５２で躯体５に共に固定してある。
As shown in FIGS. 1, 2, and 4, on the outer peripheral side surfaces of the vertical frame 67 and the upper frame 68 of the reform frame 3, a plurality of reinforcing members 24 made of metal plates are provided at intervals in the longitudinal direction of the frames 67 and 68 (three in FIG. 4). The reinforcing member 24 is provided over substantially the entire width of the remodeling frame 3 in the prospective direction, and is attached to the vertical frame 67 and the upper frame 68 with screws 69 from the outer peripheral side. A hole 70 through which a screw 52 for fixing the remodeling frame 3 to the frame 5 is inserted is provided in the room-side end of the reinforcing member 24 in alignment with the position of the hole 53 of the remodeling frame 3 . The reforming frame 3 and the reinforcing member 24 are fixed together to the frame 5 with screws 52 on the indoor side.
本改装サッシは、このようにリフォーム枠３の外周側に補強材２４を設け、リフォーム枠３と補強材２４を室内側で躯体５に共に固定してあることで、リフォーム枠３が室内側の端部の一箇所で躯体５に片持ち状に固定してあっても、リフォーム枠３が躯体５への固定部を支点として内周側や外周側に転ぶのを防ぐことができる。なお、この補強材２４に関する点は、後述する第２～５実施形態についても同様である。
In this modified sash, the reinforcing member 24 is provided on the outer peripheral side of the remodeling frame 3, and the remodeling frame 3 and the reinforcing member 24 are fixed together to the frame 5 on the indoor side, so that even if the remodeling frame 3 is fixed to the frame 5 in a cantilever manner at one point on the indoor side, the remodeling frame 3 can be prevented from falling over to the inner peripheral side or the outer peripheral side with the fixed part to the frame 5 as a fulcrum. Note that the points regarding the reinforcing member 24 are the same for the second to fifth embodiments described later.
さらに本改装サッシは、図１に示すように、既設枠４の下枠３２の上面とリフォーム枠３の下枠７１の下面との隙間の室外側端部位置に隙間調整部品７２が配置してある。隙間調整部品７２は、前記隙間の大きさに合わせて高さ調整自在なものとなっている。リフォーム枠３の下枠７１のカバー片５０は、室外側から簡便に着脱できるように嵌め込み式になっており、カバー片５０により隙間調整部品７２が隠れている。
このように、既設枠４の下枠３２の上面とリフォーム枠３の下枠７１の下面との隙間に隙間調整部品７２が設けてあることで、リフォーム枠３の下枠７１が室外側が垂れ下がるように変形するのを防止できる。
Further, in this modified sash, as shown in FIG. 1, a gap adjustment component 72 is arranged at the outdoor end of the gap between the upper surface of the lower frame 32 of the existing frame 4 and the lower surface of the lower frame 71 of the reformed frame 3 . The gap adjusting component 72 is adjustable in height according to the size of the gap. The cover piece 50 of the lower frame 71 of the remodeling frame 3 is of a fitting type so that it can be easily attached and detached from the outdoor side, and the gap adjusting part 72 is hidden by the cover piece 50.例文帳に追加
In this way, the gap adjusting part 72 is provided in the gap between the upper surface of the lower frame 32 of the existing frame 4 and the lower surface of the lower frame 71 of the remodeling frame 3, so that the lower frame 71 of the remodeling frame 3 can be prevented from being deformed such that the outdoor side hangs down.
樹脂額縁２７は、樹脂製の押出形材よりなり、図１，２に示すように、新設枠１の樹脂アングル３９と連続して室内側に延びる見込面部７３と、見込面部７３の室内側端部より外周側に向けて延びる見付面部７４を有している。見込面部７３には、新設枠１の樹脂アングル３９が内周側からねじ７５でねじ止めしてある。見付面部７４は、室外側面に内外周方向に間隔をおいて折取り自在部７６が複数設けてあり、既設額縁３４から新設枠１の樹脂アングル３９までの距離に応じて、見付面部７４を折取り自在部７６で適宜折取ることで、見付寸法を調節できるようにしてある。既設額縁３４には、アングル状の化粧材７７が取付けてあり、化粧材７７で見付面部７４の先端と既設額縁３４との隙間を隠してある。
本改装サッシは、このように樹脂額縁２７を取付けることで、樹脂額縁２７で既設枠４と取付補助材６とリフォーム枠３が隠れるので、意匠性が良い。しかも、樹脂額縁２７は新設枠１の樹脂アングル３９と連続する見込面部７３と、見込面部７３の室内側端部より外周側に延びる見付面部７４とで断面Ｌ形に形成してあることで、内観意匠をより一層向上できる。
The resin frame 27 is made of an extruded resin profile, and as shown in FIGS. 1 and 2, has a projection surface portion 73 that extends into the room continuously with the resin angle 39 of the new frame 1, and a projection surface portion 74 that extends from the indoor end of the projection surface portion 73 toward the outer peripheral side. The resin angle 39 of the newly installed frame 1 is screwed to the projection surface portion 73 with a screw 75 from the inner peripheral side. The viewing surface portion 74 has a plurality of breakable portions 76 provided at intervals in the inner and outer peripheral directions on the outdoor side surface, and depending on the distance from the existing frame 34 to the resin angle 39 of the new frame 1, the viewing surface portion 74 is appropriately broken off by the breakable portion 76 so that the viewing size can be adjusted. An angle-shaped decorative material 77 is attached to the existing frame 34, and the gap between the tip of the viewing surface portion 74 and the existing frame 34 is hidden by the decorative material 77. - 特許庁
By attaching the resin frame 27 in this manner, the refurbished sash hides the existing frame 4, the mounting auxiliary member 6, and the reformed frame 3 with the resin frame 27, so that the design is excellent. Moreover, the resin picture frame 27 is formed to have an L-shaped cross section by the projection surface part 73 continuous with the resin angle 39 of the new frame 1 and the projection surface part 74 extending from the indoor-side end part of the projection surface part 73 to the outer peripheral side, so that the interior design can be further improved.
次に、本改装サッシの施工手順を説明する。まず、図５，６に示すように、既設枠４の室内側に取付補助材６をねじ６３で取付ける。その際、取付補助材６は、見付壁５９ａ，５９ｂを折取り自在部６１で適宜折取って、既設枠４の内周側に最も飛び出した部分６２と取付補助材６の見込壁６０が見込方向で略同面になるように見付寸法を調整した上で、取付補助材６の室外側の見付壁５９ａを既設枠４の室内側壁に当接して見込方向に位置決めして取付ける。
次に、既設枠４と取付補助材６に跨って既設枠側防水テープ７を取付け、且つ取付補助材６の見込壁６０から既設額縁３４に跨ってねじ隠し用防水テープ６６を取付ける。
次に、リフォーム枠３を組み立てる。リフォーム枠３の組み立ては、予め枠組みした新設枠１の周囲に外周枠２の上枠４５と下枠４６と左右の縦枠４７，４７をそれぞれ位置決め部５４で位置決めしながら外周側から被せ、上下枠４５，４６の端面を縦枠４７，４７の内周側面にシール材５６を介して突き当て、側方から縦枠４７に挿通したねじ１０３を上下枠４５，４６のタッピングホール４８にねじ込むことで枠組みする。その後、縦枠４７，４７と上枠４５の外周側面に補強材２４を取付ける。なお、リフォーム枠３の組み立ては、改装サッシの施工現場で行ってもよいが、工場で組み立てて施工現場に搬入することもできる。
次に、上記のとおり新設枠１と外周枠２とを一体化したリフォーム枠３を、図５，６に示すように、既設枠４が取り付いた開口部２６に室外側から嵌め込み、リフォーム枠３の室内側端（外周枠２の室内側端）６４が取付補助材６の室内側端と一致するようにリフォーム枠３を見込方向に位置決めする。また、リフォーム枠３の下枠７１のカバー片５０をいったん取り外し、隙間調整部品７２の高さを既設枠４の下枠３２とリフォーム枠３の下枠７１との隙間の大きさに合わせて調整した後、カバー片５０を取付ける。その後、リフォーム枠３を室内側で内周側からねじ５２で躯体に固定する。その後、取付補助材６とリフォーム枠３に跨ってリフォーム枠側防水テープ８を取付ける。

Next, the construction procedure of this refurbished sash will be explained. First, as shown in Figs. At that time, the attachment walls 59a and 59b of the attachment support member 6 are properly broken off by the breakable portion 61, and after adjusting the attachment dimension so that the portion 62 protruding most toward the inner peripheral side of the existing frame 4 and the projection wall 60 of the attachment support member 6 are substantially flush with each other in the projection direction, the attachment wall 59a on the outdoor side of the attachment support member 6 contacts the indoor side wall of the existing frame 4 and is positioned in the projection direction.
Next, the existing frame-side waterproof tape 7 is attached across the existing frame 4 and the mounting auxiliary member 6, and the screw hiding waterproof tape 66 is attached across the existing frame 34 from the projection wall 60 of the mounting auxiliary member 6. - 特許庁
Next, the reform frame 3 is assembled. To assemble the remodeling frame 3, the upper and lower frames 45 and 46 of the outer peripheral frame 2 and the left and right vertical frames 47, 47 are placed around the new frame 1, which has been framed in advance, from the outer peripheral side while being positioned by the positioning part 54, the end surfaces of the upper and lower frames 45, 46 are abutted against the inner peripheral side surfaces of the vertical frames 47, 47 via the sealing material 56, and the screws 103 passed through the vertical frames 47 from the sides are screwed into the tapping holes 48 of the upper and lower frames 45, 46. do. After that, the reinforcement member 24 is attached to the outer peripheral side surfaces of the vertical frames 47 , 47 and the upper frame 45 . The remodeling frame 3 may be assembled at the construction site of the refurbished sash, but it may be assembled at a factory and carried to the construction site.
Next, as shown in FIGS. 5 and 6, the remodeling frame 3 obtained by integrating the new frame 1 and the outer peripheral frame 2 as described above is fitted into the opening 26 to which the existing frame 4 is attached from the outdoor side, and the remodeling frame 3 is positioned in the prospective direction so that the indoor end of the remodeling frame 3 (the indoor end of the outer peripheral frame 2) 64 coincides with the indoor end of the mounting aid 6. In addition, the cover piece 50 of the lower frame 71 of the remodeling frame 3 is once removed, and the height of the gap adjusting part 72 is adjusted according to the size of the gap between the lower frame 32 of the existing frame 4 and the lower frame 71 of the remodeling frame 3, and then the cover piece 50 is attached. After that, the reforming frame 3 is fixed to the frame with screws 52 from the inner peripheral side inside the room. Thereafter, the remodeling frame side waterproof tape 8 is attached across the mounting auxiliary member 6 and the remodeling frame 3. - 特許庁
After that, the resin frame 27 is attached from the indoor side.
図２５，２６は、第１実施形態の改装サッシの変形例であって、浴室の窓に適用したものとなっている。以下、通常の居室の窓（図１，２参照）と異なる点について説明する。
まず、ねじ隠し用防水テープ６６が外周側に延長され、その外周側端部を躯体（額縁３４）に接着してある。次に、新設枠１の室内側と外周枠２の室内側に跨ってリフォーム枠側防水テープ１０４が四周連続して設けてある。さらに、樹脂額縁２７の見付片部７４の先端と既設額縁３４との隙間をアングル状の化粧材７７で隠す代わりにシール材１０５でシールしてある。
このようにすることで本実施形態の改装サッシは、浴室側から水がかかった際に、浴室側からの躯体への浸水を防ぐことができる。
Figures 25 and 26 show a modification of the modified sash of the first embodiment, which is applied to a bathroom window. Differences from the window of a normal living room (see FIGS. 1 and 2) will be described below.
First, the screw concealing waterproof tape 66 is extended to the outer peripheral side, and its outer peripheral side end portion is adhered to the frame (frame 34). Next, a remodeling frame side waterproof tape 104 is continuously provided on four circumferences across the indoor side of the new frame 1 and the indoor side of the outer peripheral frame 2 . Furthermore, instead of hiding the gap between the front end of the tab portion 74 of the resin frame 27 and the existing frame 34 with the angle-shaped decorative material 77, the sealing material 105 is used to seal the gap.
By doing so, the refurbished sash of this embodiment can prevent water from entering the frame from the bathroom side when water is splashed from the bathroom side.
以上に述べたように本改装サッシは、四周枠組みした新設枠１の周囲を外周枠２で囲んで枠組みし、新設枠１と外周枠２を一体化した状態で既設枠４が取り付いた開口部２６に室外側から嵌め込み外周枠２を躯体５に固定することで、既設枠４を加工したり、既設枠４の内周側に部材を取付けたりする必要がないため、施工性が良い。外周枠２の躯体５への固定を室内側で行うことで、施工性がより一層向上する。
As described above, the refurbished sash has good workability because it is not necessary to process the existing frame 4 or attach a member to the inner peripheral side of the existing frame 4 by fitting the new frame 1 and the peripheral frame 2 in an integrated state into the opening 26 attached to the existing frame 4 from the outdoor side and fixing the peripheral frame 2 to the frame 5. By fixing the outer peripheral frame 2 to the frame 5 on the indoor side, workability is further improved.
図９は、本発明の改装サッシの第２実施形態を示している。本改装サッシは、第１実施形態と同様に引き違い窓に適用したものであって、既設枠４の下枠３２がアングル７８付きとなっている点が異なる。下枠３２側の取付補助材７９は、アルミ形材よりなる略帯板状の部品となっている。この取付補助材７９は、室外側の下面に折取り自在部８０が設けてあり、折取り自在部８０で折取ることで見込寸法を調節自在となっている。この取付補助材７９は、室内側端が既設枠４の室外側端から一定の寸法Ａ（具体的には、１１０ｍｍ）となるように見込方向に位置決めし、室外側部を既設枠４の下枠３２のアングル７８上に重ね、室内側部をねじ６３で躯体５に固定してある。
Figure 9 shows a second embodiment of the retrofit sash of the invention. This refurbished sash is applied to a double sliding window as in the first embodiment, and differs in that the lower frame 32 of the existing frame 4 is provided with an angle 78 . The mounting support member 79 on the lower frame 32 side is a substantially strip-shaped component made of an aluminum profile. This attachment support member 79 has a breakable portion 80 provided on the lower surface of the outdoor side, and by breaking off the breakable portion 80, the estimated dimension can be adjusted. This mounting support member 79 is positioned in the prospective direction so that the indoor side end is a certain dimension A (specifically, 110 mm) from the outdoor side end of the existing frame 4, the outdoor side portion is overlapped on the angle 78 of the lower frame 32 of the existing frame 4, and the indoor side portion is fixed to the frame 5 with screws 63.
図１０は、前記取付補助材７９を見込方向に位置決めするために用いられる治具８１を示している。この治具８１は、リフォーム枠３の下枠７１の外形に沿う形に切断された板状の部材となっており、既設枠４の下枠３２の室外側端に当接する当接部８２と、取付補助材７９を収納できる凹部８３が設けてある。図１０（ａ），（ｂ）に示すように、凹部８３に取付補助材７９を収納し、当接部８２を既設枠４の下枠３２の室外側端に当接させつつ本治具８１を既設枠４の下枠３２に上方から当てがうことで、取付補助材７９をその室内側端が既設枠４の下枠３２の室外側端から一定の寸法Ａとなるように位置決めされる。
FIG. 10 shows a jig 81 that is used to position the mounting aid 79 in the prospective direction. This jig 81 is a plate-shaped member cut along the outer shape of the lower frame 71 of the reforming frame 3, and is provided with a contact portion 82 that contacts the outdoor end of the lower frame 32 of the existing frame 4 and a concave portion 83 that can accommodate the mounting auxiliary material 79. As shown in FIGS. 10(a) and 10(b), the auxiliary mounting member 79 is housed in the recess 83, and the jig 81 is applied to the lower frame 32 of the existing frame 4 from above while the abutting portion 82 is brought into contact with the outdoor end of the lower frame 32 of the existing frame 4. Thus, the indoor end of the auxiliary mounting member 79 is positioned at a constant dimension A from the outdoor end of the lower frame 32 of the existing frame 4.
このように取付補助材７９をその室内側端が既設枠４の室外側端から一定の寸法Ａとなるように位置決めして躯体５に固定し、リフォーム枠３の室内側端６４と取付補助材７９の室内側端とが一致するようにリフォーム枠３を位置決めして躯体５に固定することで、第１実施形態と同様に、リフォーム枠３のカバー片５０と既設枠４の室外側壁との隙間が気密材５８ａ，５８ｂで止水される。
In this way, the auxiliary mounting member 79 is positioned such that the indoor end thereof is a certain dimension A from the outdoor end of the existing frame 4 and is fixed to the frame 5. By positioning the reforming frame 3 so that the indoor end 64 of the reforming frame 3 coincides with the indoor end of the mounting auxiliary member 79 and fixing it to the frame 5, the gap between the cover piece 50 of the reforming frame 3 and the outdoor wall of the existing frame 4 is filled with airtight members 58a and 58b, as in the first embodiment. The water is stopped at
図１１は、第２実施形態の改装サッシの変形例であって、既設枠４の見込寸法Ｂが図９のものより小さい場合を示している（具体的には、図９の既設枠４の見込寸法Ｂは７０ｍｍ、図１１の既設枠４の見込寸法Ｂは６０ｍｍ）。この場合でも、取付補助材７９をその室内側端の位置が既設枠４の室外側端から一定の寸法Ａ（具体的には１１０ｍｍ）となるように取付ける点は同じであり、既設枠４の見込寸法Ｂが小さくなった分（１０ｍｍ）だけ取付補助材７９が室内側に移動する。
逆に、既設枠４の見込寸法Ｂが図９のものより大きい場合には、取付補助材７９はその分だけ室外側に移動する。取付補助材７９を室外側に移動させたときに、取付補助材７９の室外側端部が既設枠４の室内側壁よりも室外側に飛び出す場合には、折取り自在部８０で折取って取付補助材７９の見付寸法を小さくする。
FIG. 11 is a modification of the modified sash of the second embodiment, showing a case where the estimated dimension B of the existing frame 4 is smaller than that of FIG. 9 (specifically, the estimated dimension B of the existing frame 4 in FIG. 9 is 70 mm, and the estimated dimension B of the existing frame 4 in FIG. 11 is 60 mm). In this case as well, the auxiliary mounting member 79 is attached so that the position of the indoor end thereof is a constant dimension A (specifically, 110 mm) from the outdoor end of the existing frame 4, and the auxiliary mounting member 79 moves to the indoor side by the amount (10 mm) that the estimated dimension B of the existing frame 4 is reduced (10 mm).
Conversely, if the estimated dimension B of the existing frame 4 is larger than that shown in FIG. 9, the auxiliary mounting member 79 moves to the outdoor side by that amount. When the mounting auxiliary material 79 is moved to the outdoor side, if the outdoor side end part of the mounting auxiliary material 79 protrudes to the outdoor side from the indoor side wall of the existing frame 4, the mounting auxiliary material 79 is broken off by a breakable part 80 to reduce the outside dimension of the mounting auxiliary material 79. - 特許庁
図１２，１３は、本発明の改装サッシの第３実施形態を示している。本実施形態の改装サッシは、外周枠２の上枠４５と縦枠４７が、見込方向に延びる部分８４と室外側で外周側に延びるカバー片５０とが一体成形された略Ｌ形断面の形材となっている。このように、外周枠２の上枠４５と縦枠４７を一体成形の形材とすることで、部材の点数を減らし、リフォーム枠３の組み立てに要する時間と手間を省くことができる。
Figures 12 and 13 show a third embodiment of the retrofit sash of the invention. In the modified sash of this embodiment, the upper frame 45 and the vertical frame 47 of the outer peripheral frame 2 are formed into a substantially L-shaped cross section integrally formed with a portion 84 extending in the viewing direction and a cover piece 50 extending to the outer peripheral side on the outdoor side. By integrally forming the upper frame 45 and the vertical frame 47 of the outer peripheral frame 2 in this way, the number of members can be reduced, and the time and labor required for assembling the reforming frame 3 can be saved.
また本実施形態の改装サッシは、図１４に示すように、補強板２５が外周枠２の縦枠４７の外周側に設けてある。すなわち補強板２５は、外周枠２の縦枠４７の外周側面の上部と下部の２箇所に外周枠２の上枠４５と下枠４６の側方の位置に配置され、外周側から補強板２５と縦枠４７に貫通したネジ１０３を上枠４５と下枠４６のタッピングホール４８に螺入することで、補強板２５と縦枠４７を上枠４５及び下枠４６に共締めしてある。上枠４５及び下枠４６の長手方向の端面と縦枠４７の内周側面との間には、シール材５６を介在させてある。補強板２５は、室外側の端部を縦枠４７の外周側に向けて突出するカバー片５０に突き当ててある。
このように、外周枠２の縦枠４７の外周側に補強板２５を設けた場合でも、新設枠１の縦枠３７の外周側に補強板２５を設けた場合と同様に、障子２８，２９を勢いよく閉めたときなどに縦枠４７が外周側に広がるように変形するのを防止し、水密性を維持することができる。
Further, in the modified sash of this embodiment, as shown in FIG. That is, the reinforcing plate 25 is arranged in two places, namely, the upper part and the lower part of the outer peripheral side surface of the vertical frame 47 of the outer peripheral frame 2, at the lateral positions of the upper frame 45 and the lower frame 46 of the outer peripheral frame 2. The reinforcing plate 25 and the vertical frame 47 are fastened together to the upper frame 45 and the lower frame 46 by screwing the screws 103 penetrating the reinforcing plate 25 and the vertical frame 47 from the outer peripheral side into the tapping holes 48 of the upper frame 45 and the lower frame 46. A sealing material 56 is interposed between the longitudinal end surfaces of the upper frame 45 and the lower frame 46 and the inner peripheral side surface of the vertical frame 47 . The reinforcing plate 25 abuts against a cover piece 50 protruding toward the outer peripheral side of the vertical frame 47 at its outdoor end.
Thus, even when the reinforcing plate 25 is provided on the outer peripheral side of the vertical frame 47 of the outer peripheral frame 2, it is possible to prevent the vertical frame 47 from being deformed so as to spread to the outer peripheral side when the shoji 28, 29 are vigorously closed, and to maintain the watertightness, as in the case of providing the reinforcing plate 25 on the outer peripheral side of the vertical frame 37 of the new frame 1. - 特許庁
図１５，１６は、本発明の改装サッシの第４実施形態を示している。本実施形態の改装サッシは、既設枠４が雨戸８５付きのサッシ枠となっている。図１５に示すように、既設枠の上枠３１は、雨戸８５の上部を案内する案内溝８６が室外側に張り出して設けてあり、既設枠４の下枠３２には雨戸８５の下部を案内するレール８７が室外側に張り出して設けてある。
Figures 15 and 16 show a fourth embodiment of the retrofit sash of the invention. In the refurbished sash of this embodiment, the existing frame 4 is a sash frame with shutters 85 attached. As shown in FIG. 15, the upper frame 31 of the existing frame is provided with a guide groove 86 projecting to the outdoor side for guiding the upper part of the rain door 85, and the lower frame 32 of the existing frame 4 is provided with a rail 87 projecting to the outdoor side for guiding the lower part of the rain door 85.
リフォーム枠３の外周枠２は、第１実施形態と同様に、上枠４５と縦枠４７が見込方向に延びる主部材４９と、主部材４９の室外側端部に着脱自在に取付けたカバー片５０とからなる分割タイプとなっており、上枠４５はカバー片５０の代わりに補助材２２を取付けている。
補助材２２は、上枠４５の主部材４９に係止する係止部８８と、既設枠４の上枠３１の垂下片２０と見込方向に重合する見付片８９を有し、見付片８９の室内側面に乾式のシール材２３が設けてあり、シール材２３が垂下片２０の室外側面に圧着している。補助材２２は、係止部８８を上枠３１の主部材４９に係止した状態で、室外側からのねじ９０で下部を主部材４９の室外側面に固定してある。
縦枠４７のカバー片５０は、図１６に示すように、第１実施形態のものと同じものを使用しており、既設枠４の縦枠３３と干渉する部分を折取り自在部５５で切除してある。縦枠４７のカバー片５０の室内側面には乾式のシール材９１が設けてあり、このシール材９１は上枠４５の補助材２２のシール材２３と連続している。既設枠４の縦枠３３にも乾式のシール材９２が設けてあり、このシール材９２と外周枠２の縦枠４７のカバー片５０のシール材９１とが圧着している。
As in the first embodiment, the outer peripheral frame 2 of the reforming frame 3 is of a split type consisting of a main member 49 in which an upper frame 45 and a vertical frame 47 extend in the prospective direction, and a cover piece 50 detachably attached to the outdoor end of the main member 49, and the upper frame 45 is attached with an auxiliary member 22 instead of the cover piece 50.
The auxiliary member 22 has a locking portion 88 that locks to the main member 49 of the upper frame 45, and a support piece 89 that overlaps the hanging piece 20 of the upper frame 31 of the existing frame 4 in the direction of projection. The auxiliary member 22 has its lower portion fixed to the outdoor side surface of the main member 49 with a screw 90 from the outdoor side in a state where the locking portion 88 is locked to the main member 49 of the upper frame 31 .
As shown in FIG. 16, the cover piece 50 of the vertical frame 47 is the same as that of the first embodiment, and the portion of the existing frame 4 that interferes with the vertical frame 33 is cut off by the breakable portion 55. A dry sealing member 91 is provided on the indoor side surface of the cover piece 50 of the vertical frame 47 , and the sealing member 91 is continuous with the sealing member 23 of the auxiliary member 22 of the upper frame 45 . A dry sealing material 92 is also provided on the vertical frame 33 of the existing frame 4 , and the sealing material 92 and the sealing material 91 of the cover piece 50 of the vertical frame 47 of the outer peripheral frame 2 are crimped.
本実施形態の改装サッシは、第１実施形態と同様に、新設枠１と外周枠２を一体化したリフォーム枠３を、既設枠４が取り付いた開口部２６に室外側から嵌め込み、外周枠２を室内側で躯体５に固定する。リフォーム枠３を開口部２６に室外側から嵌め込む際、外周枠２の上枠４５の補助材２２は取外しておき、リフォーム枠３を躯体５に固定してからシール材２３付きの補助材２２を上枠４５の主部材４９の室外側面にねじ９０で取付け、既設枠４の上枠３１とリフォーム枠３の上枠４５間を止水する。
In the refurbished sash of this embodiment, similarly to the first embodiment, a reformed frame 3 in which a new frame 1 and a peripheral frame 2 are integrated is fitted into an opening 26 to which an existing frame 4 is attached from the outdoor side, and the peripheral frame 2 is fixed to the frame 5 on the indoor side. When the remodeling frame 3 is fitted into the opening 26 from the outdoor side, the auxiliary material 22 of the upper frame 45 of the outer peripheral frame 2 is removed, and after fixing the remodeling frame 3 to the frame 5, the auxiliary material 22 with the sealing material 23 is attached to the outdoor side surface of the main member 49 of the upper frame 45 with screws 90 to stop water between the upper frame 31 of the existing frame 4 and the upper frame 45 of the remodeling frame 3.
このように本実施形態の改装サッシは、リフォーム枠３の上枠４５の室外側面に補助材２２を着脱自在に設け、補助材２２には既設枠４の上枠３１の内周側の垂下片２０との間の隙間をシールするシール材２３を有しているので、当該補助材２２を取り外した状態でリフォーム枠３を既設枠４が取り付いた開口部２６に室外側から嵌め込み、その後に補助材２２を上枠４５の室外側面に取付けるだけで既設枠４の上枠３１とリフォーム枠３の上枠４５との隙間をシールでき、施工性が良い。補助材２２に既設枠４の垂下片２０と見込方向に重合する見付片８９を有することで、補助材２２と既設枠４の垂下片２０との間にシール材２３を設けるのが容易である。
リフォーム枠３の外周枠２を、主部材４９とカバー片５０とに分割して形成したことで、既設枠４の形状の違いや壁への納まりの違い等に対して、カバー片５０の形状を変更することで柔軟に対応することができる。
As described above, in the modified sash of this embodiment, the auxiliary material 22 is detachably provided on the outdoor side surface of the upper frame 45 of the remodeling frame 3, and the auxiliary material 22 has the sealing material 23 for sealing the gap between the upper frame 31 of the existing frame 4 and the hanging piece 20 on the inner peripheral side of the existing frame 4. Therefore, with the auxiliary material 22 removed, the remodeling frame 3 is fitted from the outdoor side into the opening 26 to which the existing frame 4 is attached, and then the auxiliary material 22 is fitted from the outdoor side of the upper frame 45. The gap between the upper frame 31 of the existing frame 4 and the upper frame 45 of the remodeling frame 3 can be sealed by simply attaching it to the existing frame 4, and workability is good. By providing the support member 22 with the hanging piece 89 overlapping the hanging piece 20 of the existing frame 4 in the direction of projection, it is easy to provide the sealing material 23 between the auxiliary member 22 and the hanging piece 20 of the existing frame 4 .
By forming the outer peripheral frame 2 of the remodeling frame 3 by dividing it into the main member 49 and the cover piece 50, it is possible to flexibly cope with the difference in the shape of the existing frame 4 and the difference in fitting to the wall by changing the shape of the cover piece 50.例文帳に追加
図１７，１８は、本発明の改装サッシの第５実施形態を示している。本実施形態の改装サッシは、第４実施形態と同様に、既設枠４が雨戸８５付きのサッシ枠となっている。
リフォーム枠３は、外周枠２の上枠４５と縦枠４７が、第３実施形態と同様に、見込方向に延びる部分８４と室外側のカバー片５０とが一体成形されたものとなっている。外周枠２の上枠４５は、図１７に示すように、リフォーム枠３を開口部２６に室外側から嵌め込む際に邪魔にならないように、カバー片５０を根元付近の折取り自在部５５で折取ってある。
既設枠４の上枠３１の内周側の垂下片２０には、補助材１９が両面テープ９３で接着して取付けてある。補助材１９は、下端部にリフォーム枠３の外周側面と対向する見込片９４を有している。そして、補助材１９の見込片９４と外周枠２の上枠４５の室外側端部との隙間を、湿式のシール材２１を充填することでシールしてある。図１７中の符合９５は、シール材２１の受けとなるバックアップ材である。
リフォーム枠３の外周枠２の縦枠４７は、図１８に示すように、カバー片５０の既設枠４の縦枠３３と干渉する部分を折取り自在部５５で折取って切除してあり、外周枠２の縦枠４７と既設枠４の縦枠３３との隙間を、湿式のシール材９６を充填することでシールしてある。既設枠４の上枠３１と外周枠２の上枠４５間のシール材２１と、既設枠４の縦枠３３と外周枠２の縦枠４７間のシール材９６とは、連続している。
Figures 17 and 18 show a fifth embodiment of the retrofit sash of the invention. In the refurbished sash of this embodiment, the existing frame 4 is a sash frame with shutters 85 as in the fourth embodiment.
In the reforming frame 3, the upper frame 45 and the vertical frame 47 of the outer peripheral frame 2 are formed integrally with the portion 84 extending in the viewing direction and the cover piece 50 on the outdoor side, as in the third embodiment. As shown in FIG. 17, the upper frame 45 of the outer peripheral frame 2 has a cover piece 50 that is snapped off at a snap-off portion 55 near the base so as not to interfere when fitting the reform frame 3 into the opening 26 from the outside.
An auxiliary material 19 is attached to the hanging piece 20 on the inner peripheral side of the upper frame 31 of the existing frame 4 by bonding with a double-faced tape 93 . The auxiliary member 19 has a projection piece 94 facing the outer peripheral side surface of the reform frame 3 at its lower end. The gap between the projection piece 94 of the auxiliary member 19 and the outdoor end of the upper frame 45 of the outer peripheral frame 2 is sealed by filling it with a wet sealing material 21 . Reference numeral 95 in FIG. 17 denotes a backup material that receives the sealing material 21 .
As shown in FIG. 18, the vertical frame 47 of the outer peripheral frame 2 of the remodeling frame 3 is cut off by breaking off the portion of the cover piece 50 that interferes with the vertical frame 33 of the existing frame 4 with a breakable portion 55, and the gap between the vertical frame 47 of the outer peripheral frame 2 and the vertical frame 33 of the existing frame 4 is sealed by filling a wet sealing material 96. The sealing material 21 between the upper frame 31 of the existing frame 4 and the upper frame 45 of the peripheral frame 2 and the sealing material 96 between the vertical frame 33 of the existing frame 4 and the vertical frame 47 of the peripheral frame 2 are continuous.
このように本実施形態の改装サッシは、リフォーム枠３を外周枠２のカバー片５０を適宜折取った状態で既設枠４が取り付いた開口部２６に室外側から嵌め込み、既設枠４の内周側の垂下片２０に補助材１９を取付け、リフォーム枠３の外周側と補助材１９との間をシール材２１でシールすることで、既設枠４が雨戸８５付きサッシの場合でも容易に施工することができる。補助材１９にリフォーム枠３の外周側面と対向する見込片９４を有することで、補助材１９とリフォーム枠３との間にシール材２１を設けるのが容易である。
In this way, the refurbished sash of the present embodiment can be easily constructed even if the existing frame 4 is a sash with a rain door 85 by fitting the remodeling frame 3 into the opening 26 to which the existing frame 4 is attached from the outdoor side with the cover piece 50 of the outer peripheral frame 2 broken off as appropriate, attaching the auxiliary material 19 to the hanging piece 20 on the inner peripheral side of the existing frame 4, and sealing the space between the outer peripheral side of the remodeling frame 3 and the auxiliary material 19 with the sealing material 21. By providing the auxiliary member 19 with the projection piece 94 facing the outer peripheral side surface of the reforming frame 3 , it is easy to provide the sealing member 21 between the auxiliary member 19 and the reforming frame 3 .
図１９，２０は、本発明の改装サッシの第６実施形態を示している。本改装サッシは、勝手口ドアに適用したものであって、既設枠４が取り付いた開口部２６に室外側から納めて躯体５に固定したリフォーム枠３と、リフォーム枠３の吊元側縦枠６７ａに蝶番９７にて室外側に回動して開くように取付けた戸９８を備えている。

本改装サッシは、図２２，２３に示すように、新設枠１と外周枠２を一体化した状態で既設枠４が取り付いた開口部２６に室外側から嵌め込み、外周枠２を室内側で内周側からのねじ５２で躯体５に固定してある。さらに、新設枠１の下枠３６も室内側で内周側からのねじ１０１で躯体５に固定してある。
このように本改装サッシは、四周枠組みした新設枠１の上方及び左右の三方を外周枠２で囲んで枠組みし、新設枠１と外周枠２を一体化した状態で既設枠４が取り付いた開口部２６に室外側から嵌め込み外周枠２を躯体５に固定することで、既設枠４を加工したり、既設枠４の内周側に部材を取付けたりする必要がないため、施工性が良い。外周枠２の躯体５への固定を室内側で行うことで、施工性がより一層向上する。
As shown in FIGS. 22 and 23, in this refurbished sash, the new frame 1 and the outer peripheral frame 2 are integrated and fitted from the outdoor side into the opening 26 to which the existing frame 4 is attached, and the outer peripheral frame 2 is fixed to the frame 5 with screws 52 from the inner peripheral side on the indoor side. Further, the lower frame 36 of the new frame 1 is also fixed to the frame 5 by screws 101 from the inner peripheral side inside the room.
In this way, the refurbished sash is framed by enclosing the upper and left and right sides of the new frame 1, which is four-circumferentially framed, with the outer peripheral frame 2, and in a state in which the new frame 1 and the outer peripheral frame 2 are integrated, the existing frame 4 is attached to the opening 26. By fitting the outer peripheral frame 2 to the frame 5 from the outdoor side and fixing the outer peripheral frame 2 to the frame 5, there is no need to process the existing frame 4 or attach members to the inner peripheral side of the existing frame 4, so workability is good. By fixing the outer peripheral frame 2 to the frame 5 on the indoor side, workability is further improved.
リフォーム枠３の戸先側縦枠６７ｂは、図２０に示すように、内周側面に戸９８に取り付けてあるラッチ錠１０２と係合する錠受け１６が取付けてある。錠受け１６の近傍のリフォーム枠３の戸先側縦枠６７ｂの外周側面と既設枠４の縦枠３３の内周側面との間にはスペーサー１７が設けてあり、スペーサー１７によりリフォーム枠３の戸先側縦枠６７ｂと既設枠４の縦枠３３との隙間１８を狭めてある。図示の例では、スペーサー１７は戸先側縦枠６７ｂの外周側面にねじ止めしてあるが、スペーサー１７を既設枠４の縦枠３３の内周側面にねじ止めしてあってもよい。
As shown in FIG. 20, the front side vertical frame 67b of the remodeling frame 3 is provided with a lock receiver 16 that engages with the latch lock 102 attached to the door 98 on the inner peripheral surface thereof. A spacer 17 is provided between the outer peripheral side surface of the front side vertical frame 67b of the remodeling frame 3 in the vicinity of the lock holder 16 and the inner peripheral side surface of the vertical frame 33 of the existing frame 4, and the spacer 17 narrows the gap 18 between the door front side vertical frame 67b of the remodeling frame 3 and the vertical frame 33 of the existing frame 4. In the illustrated example, the spacer 17 is screwed to the outer peripheral side surface of the door leading side vertical frame 67 b , but the spacer 17 may be screwed to the inner peripheral side surface of the vertical frame 33 of the existing frame 4 .
本改装サッシは、リフォーム枠３が室内側だけで躯体５に固定してあるため、図２４（ａ）に示すように、戸９８に負圧が働いて戸９８が室外側に押されると、ラッチ錠１０２に錠受け１６が引っ張られて戸先側縦枠６７ｂが躯体５とのねじ５２による固定部を支点として外周側に転ぼうとするが、先に述べたように、錠受け１６の近傍のリフォーム枠３の戸先側縦枠６７ｂの外周側面と既設枠４の縦枠３３の内周側面との間にスペーサー１７を設け、スペーサー１７によりリフォーム枠３の戸先側縦枠６７ｂと既設枠４の縦枠３３との隙間１８を狭めてあることで、スペーサー１７により戸先側縦枠６７ｂの転びが規制され、ラッチ錠１０２が錠受け１６から外れるのを防ぐことができる。
図２４（ｂ）は、スペーサー１７が無い場合の比較例を示している。同図に示すように、スペーサー１７が無い場合には、戸９８に負圧が働いて戸９８が室外側に押されると、ラッチ錠１０２に錠受け１６が引っ張られて戸先側縦枠６７ｂが躯体５との固定部を支点として外周側に大きく転び、ラッチ錠１０２が錠受け１６から外れ、戸９８が勝手に開くおそれがある。
In this refurbished sash, since the reformed frame 3 is fixed to the frame 5 only on the indoor side, as shown in FIG. A spacer 17 is provided between the outer peripheral side surface of the door leading side vertical frame 67b and the inner peripheral side surface of the vertical frame 33 of the existing frame 4, and by narrowing the gap 18 between the door leading side vertical frame 67b of the remodeling frame 3 and the vertical frame 33 of the existing frame 4, the spacer 17 restricts the door leading side vertical frame 67b from falling and prevents the latch lock 102 from coming off from the lock holder 16.
FIG. 24(b) shows a comparative example without the spacer 17. FIG. As shown in the figure, when the spacer 17 is not provided, when the door 98 is pushed outward by a negative pressure, the lock 16 is pulled by the latch lock 102, causing the front side vertical frame 67b to fall greatly to the outer peripheral side with the fixed portion to the frame 5 as a fulcrum.
以上に述べたように本改装サッシ（第１，２，３，４，５実施形態）は、新設枠１と外周枠２とを備え、新設枠１は、四周枠組みしてあり、外周枠２は、新設枠１の周囲を囲んで枠組みしてあり、新設枠１と外周枠２を一体化した状態で既設枠４が取り付いた開口部２６に室外側から嵌め込み外周枠２を躯体５に固定するため、施工性が良い（請求項１に係る発明）。
