The protruding piece 28 is located at an inner peripheral side of about 5 to 10 mm from the inner peripheral edge 30 of the indoor side wall of the flanges 15, 16, and 17, and between the tip of the protruding piece 28 and the glass surface 31 of the shoji 2. A gap 32 of about 3 mm is provided. The tip end portion 28a of the protruding piece 28 is made of a soft resin. This soft resin portion is provided by extrusion molding (so-called two-color molding) integrally with other hard resin portions.
By providing such indoor resin frame portions 11, 12, 13, and 14 on the inner periphery of the frame 1 on the indoor side, the folds 15, 16, and 17 of the shoji 2 are hidden from view from the indoor side. In addition, a space 33 having a narrow frontage and a deep depth is formed between the flanges 15, 16, and 17 of the shoji 2 and the indoor resin frame portions 11, 12, 13, and 14.
四周の室内側樹脂枠部11,12,13,14のうち下枠4の室内側樹脂枠部12は、図1に示すように、外周側部12aと内周側部12bとに分割して形成してある。このように下枠4の室内側樹脂枠部12を分割構造とすることで、オペレータハンドル22を取付けたり、オペレータハンドル22の動きをフリクションステー21bに伝える連動機構を設置したりするための加工が容易に行える。
また、図2に示すように、戸先側の竪枠6の室内側樹脂枠部14も、外周側部14aと内周側部14bとに分割して形成してある。本開口部建材は、オペレータハンドル22に替えて、障子2の戸先框17の室内側面にカムラッチハンドルを取付けることもでき、その場合は戸先側の竪枠6の室内側樹脂枠部14に切欠き加工等を行う必要があるが、室内側樹脂枠部14をこのように分割構造とすることで、加工が容易に行える。
The indoor resin frame 12 of the lower frame 4 among the four indoor resin frames 11, 12, 13, and 14 is divided into an outer peripheral portion 12a and an inner peripheral portion 12b as shown in FIG. It is formed. In this way, the interior side resin frame portion 12 of the lower frame 4 has a divided structure, so that processing for attaching the operator handle 22 or installing an interlocking mechanism for transmitting the movement of the operator handle 22 to the friction stay 21b is possible. Easy to do.
In addition, as shown in FIG. 2, the indoor side resin frame portion 14 of the door frame 6 on the door end side is also divided into an outer peripheral side portion 14a and an inner peripheral side portion 14b. In this opening construction material, instead of the operator handle 22, a cam latch handle can be attached to the indoor side surface of the door rod 17 of the shoji 2, and in that case, the indoor resin frame portion 14 of the door frame 6 on the door edge side. However, it is necessary to perform notch processing or the like, but by forming the indoor resin frame portion 14 in such a divided structure, the processing can be easily performed.
各室内側樹脂枠部11,12,13,14は、予め各金属枠部7,8,9,10に内周側から取付けられ、その上で上下枠3,4の金属枠部7,8の長手方向の端面を竪枠5,6の金属枠部9,10の内周側面に当接し、側方から挿入したネジを上下枠3,4の金属枠部7,8に形成されたタッピングホールに捩じ込んで、上下枠3,4と竪枠5,6を枠組みしている。
竪枠5,6の室内側樹脂枠部13,14と上下枠3,4の室内側樹脂枠部11,12の端部の納まりは、図3に示すように、いわゆる横勝ちの状態になっている。上下枠3,4の室内側樹脂枠部11,12の端部は、図5に示すように、突出片28に長手方向端部より竪框17から内周側に離間した位置まで達する切欠き34を設け、竪枠5,6の室内側樹脂枠部13,14は長手方向端部を直角に切断し、その切断した小口を上下枠3,4の室内側樹脂枠部11,12の内周側面35に当接している。そのため、竪枠5,6の室内側樹脂枠部13,14の突出片28は切欠き加工が不要であり、加工工数を削減できる。
図6は、上下枠3,4の室内側樹脂枠部11,12の端部の加工の他の例を示している。突出片28は、図6(b)に示すように、軟質樹脂で形成された先端部28aの室内外方向の長さが図5のものより長くなっており、また図6(a)に示すように、長手方向端部の突出片28の切欠き34を小さくすると共に、竪枠5,6の室内側樹脂枠部13,14の突出片28の外周側に隣接する位置で、突出片28に切り込み36を設けてある。このように突出片28に切り込み36を設けたことで、図6(c)に示すように、突出片28の左右の端部のみが障子2閉鎖時に変形するから、突出片28の障子2の竪框17と重合する部分を切除しなくても、障子2を閉鎖するのに支障がない。
Each indoor side resin frame portion 11, 12, 13, 14 is attached to each metal frame portion 7, 8, 9, 10 in advance from the inner peripheral side, and then the metal frame portions 7, 8 of the upper and lower frames 3, 4 are mounted thereon. The tapping formed on the metal frame portions 7 and 8 of the upper and lower frames 3 and 4 with the end faces in the longitudinal direction being in contact with the inner peripheral side surfaces of the metal frame portions 9 and 10 of the collar frames 5 and 6 The upper and lower frames 3 and 4 and the eaves frames 5 and 6 are framed by being screwed into the hole.
As shown in FIG. 3, the storage of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 and the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 is in a so-called horizontal winning state. ing. As shown in FIG. 5, the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 are notched so as to reach the projecting piece 28 from the longitudinal end portion to a position separated from the flange 17 toward the inner peripheral side. 34, and the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 are cut at the longitudinal ends at right angles, and the cut ends are formed inside the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4. It is in contact with the peripheral side surface 35. Therefore, the protruding pieces 28 of the indoor side resin frame portions 13 and 14 of the collar frames 5 and 6 do not need to be cut out, and the number of processing steps can be reduced.
FIG. 6 shows another example of processing of the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4. As shown in FIG. 6 (b), the protruding piece 28 has a length in the indoor / outdoor direction of the tip 28a formed of a soft resin longer than that in FIG. 5, and also shown in FIG. 6 (a). As described above, the notch 34 of the projecting piece 28 at the end in the longitudinal direction is reduced, and the projecting piece 28 is located at a position adjacent to the outer peripheral side of the projecting piece 28 of the indoor side resin frame parts 13, 14 of the collar frames 5, 6. An incision 36 is provided in FIG. Since the notches 36 are provided in the protruding piece 28 as described above, only the left and right end portions of the protruding piece 28 are deformed when the shoji 2 is closed as shown in FIG. There is no problem in closing the shoji 2 without excising the portion that overlaps with the scissors 17.
以上に述べたように本開口部建材は、枠1の室内側の内周部に室内側樹脂枠部11,12,13,14を設け、室内側樹脂枠部11,12,13,14は内周側面35に室外側に突出する突出片28を有し、突出片28は障子2の框15,16,17よりも内周側に位置していることで、障子2の框15,16,17が室内側樹脂枠部11,12,13,14で隠れるため、内観の見栄えが良い。さらに、突出片28の先端と障子2のガラス面31との間に隙間32が設けてあることで、図1に示すように、上框15やガラス面31等に生じた結露水37を、図中の矢印38a,38bで示すように、突出片28で堰き止めることなく流下させられ、下枠4上面(室内側樹脂枠部12の内周側面35)に結露水が滞留することがない。なお、流下した結露水は、下枠4と下框16とをシールしているタイト材25の上に滞留するが、障子2を開ければ室外に排水されるし、障子2を開けなくてもそのうちに蒸発してなくなる。
さらに本開口部建材は、室内側樹脂枠部11,12,13,14の突出片28により、障子2の框15,16,17と室内側樹脂枠部11,12,13,14との間に間口が狭く奥行の深い空間33を設けており、しかもその空間33の入り口部分33aがジグザグした形になっているため、アルミ製の框15,16,17を伝わる室外の冷気がこの空間33に滞留し、居住空間まで冷気が伝わりにくくなるため、断熱性能が向上する。また、暴風時にタイト材25を超えて噴出した雨水は、前記空間33を上昇するうちに運動エネルギーが低下して室内側に漏水しにくくなるので、水密性能も向上する。
また、室内側樹脂枠部11,12,13,14の突出片28の先端部28aを軟質樹脂で形成したことで、暴風時にガラス19が室内側に変形したり、障子2を乱暴に閉鎖したりしたときに、突出片28がガラス面31と接触したとしても、ガラス19の破損を防止することができ、前述の排水・断熱・水密性能をそのまま維持することができる。
突出片28は、框15,16,17の室内側壁の内周縁30から5〜10mm程度内周側に離間しているため、図4中に二点鎖線で示すように、障子2が開き始める際に障子2が戸先側にスライドしても、突出片28が戸尻側の竪框17と干渉することがなく、障子2の開閉が妨げられない。
さらに本開口部建材は、内観視で障子2の框15,16,17が見えないばかりか、室内側樹脂枠部11,12,13,14とガラス19との間に質感や色の異なるシール材が無いため、内観意匠をより一層向上することができる。
As described above, this opening building material is provided with the indoor resin frame portions 11, 12, 13, and 14 on the inner peripheral portion on the indoor side of the frame 1, and the indoor resin frame portions 11, 12, 13, and 14 are The inner peripheral side surface 35 has a protruding piece 28 that protrudes to the outdoor side, and the protruding piece 28 is located on the inner peripheral side with respect to the flanges 15, 16, and 17 of the shoji 2. , 17 are hidden by the indoor resin frame portions 11, 12, 13, and 14, so that the appearance of the interior is good. Furthermore, since the gap 32 is provided between the tip of the protruding piece 28 and the glass surface 31 of the shoji 2, as shown in FIG. 1, the dew condensation water 37 generated on the upper collar 15, the glass surface 31, etc. As indicated by arrows 38a and 38b in the figure, the projecting piece 28 is allowed to flow without damming, and dew condensation does not stay on the upper surface of the lower frame 4 (the inner peripheral side surface 35 of the indoor resin frame portion 12). . The condensed water that flows down stays on the tight material 25 that seals the lower frame 4 and the lower rod 16, but if the shoji 2 is opened, it is drained to the outside, and the shoji 2 is not opened. Over time it will not evaporate.
Further, the opening building material is provided between the flanges 15, 16, and 17 of the shoji 2 and the indoor resin frame portions 11, 12, 13, and 14 by the protruding pieces 28 of the indoor resin frame portions 11, 12, 13, and 14. Since the entrance 33a of the space 33 has a zigzag shape, the outdoor cold air transmitted through the aluminum cages 15, 16, and 17 is formed in the space 33. The heat insulation performance is improved because it is difficult to transmit cold air to the living space. In addition, rainwater spouted over the tight material 25 during a storm is less likely to leak into the room due to a decrease in kinetic energy as it rises in the space 33, so that watertightness is also improved.
Further, the tip portion 28a of the protruding piece 28 of the indoor side resin frame portions 11, 12, 13, 14 is formed of soft resin, so that the glass 19 is deformed indoors during a storm, or the shoji 2 is closed wildly. Even if the protruding piece 28 comes into contact with the glass surface 31 at the time, the glass 19 can be prevented from being damaged, and the above-mentioned drainage, heat insulation and watertight performance can be maintained as they are.
Since the projecting piece 28 is separated from the inner peripheral edge 30 of the indoor side wall of the flanges 15, 16, and 17 to the inner peripheral side by about 5 to 10 mm, the shoji 2 starts to open as shown by a two-dot chain line in FIG. Even when the shoji 2 slides to the door end side, the protruding piece 28 does not interfere with the heel 17 on the door bottom side, and the opening and closing of the shoji 2 is not hindered.
Furthermore, this building material for the opening portion not only shows the scissors 15, 16, 17 of the shoji 2 from the inside, but also seals with different textures and colors between the indoor resin frame portions 11, 12, 13, 14 and the glass 19. Since there is no material, the interior design can be further improved.
図7は、本発明の開口部建材の第2実施形態を示している。本実施形態は、竪枠5,6の室内側樹脂枠部13,14の形状が第1実施形態と異なっている。竪枠5,6の室内側樹脂枠部13,14は、内周側面42が室外側に向かうにつれて内周側に位置するように傾斜している。戸先側の竪枠6の室内側樹脂枠部14は、外周側部14aが第1実施形態と兼用である。
このように、内周側面42を傾斜させることで、竪枠5,6の室内側端部の見付寸法Aを小さくすることができ、内観意匠がさらに向上する。また、上下枠3,4と竪枠5,6とで室内側端部の見付寸法Aを共通にすることもできる。さらに、竪枠5,6の内周側面42とガラス面31との間の入隅部43が鈍角になるため、直角とした場合と比べて、入隅部43の拭き掃除が容易になる。
本実施形態においても、竪枠5,6の室内側樹脂枠部13,14と上下枠3,4の室内側樹脂枠部11,12の端部の納まりを、第1実施形態と同様に横勝ちの状態とすることで、竪枠5,6の室内側樹脂枠部13,14の内周側面42を傾斜させても、上下枠3,4の室内側樹脂枠部11,12の端部を斜めに切断する必要がなく、加工が容易である。
FIG. 7 shows a second embodiment of the opening building material of the present invention. In the present embodiment, the shapes of the indoor side resin frame portions 13 and 14 of the collar frames 5 and 6 are different from those of the first embodiment. The indoor side resin frame parts 13 and 14 of the eaves frames 5 and 6 are inclined so that the inner peripheral side surface 42 is positioned on the inner peripheral side as it goes to the outdoor side. As for the indoor side resin frame part 14 of the frame 6 on the door end side, the outer peripheral side part 14a is also used in the first embodiment.
Thus, by inclining the inner peripheral side surface 42, the finding dimension A of the indoor side ends of the collar frames 5 and 6 can be reduced, and the interior design is further improved. Further, the upper and lower frames 3, 4 and the eaves frames 5, 6 can have a common finding dimension A at the indoor side end. Furthermore, since the corner part 43 between the inner peripheral side surface 42 of the gutter frames 5 and 6 and the glass surface 31 becomes an obtuse angle, the wiping and cleaning of the corner part 43 is facilitated as compared with the case where it is a right angle.
Also in this embodiment, the storage of the end portions of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 and the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 is the same as in the first embodiment. Even if the inner peripheral side surfaces 42 of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 are inclined by setting the winning state, the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4. Is easy to process.
図8,9は、本発明の開口部建材の第3実施形態を示している。本実施形態のものは、障子2を枠1内に固定具(図示省略)で固定し、FIX窓としている。枠1と障子2は、第1実施形態のものと共通である。
下枠4の室内側樹脂枠部12の突出片28の先端とガラス面31との間の隙間32には、図8に示すように、ゴムや軟質樹脂で形成された隙間塞ぎ材44を内周側から挿入して取付けている。これにより、障子2を開閉できないFIX窓において、下枠4の室内側樹脂枠部12の突出片28の先端とガラス面31との間の隙間32に異物が落下して取り出しが困難となったり、意匠が低下したりするのを防ぐことができる。しかも、図9に示すように、竪枠5,6の室内側樹脂枠部13,14の突出片28の先端とガラス面31との間には隙間32があるため、ガラス面31に生じた結露水は隙間塞ぎ材44の上に落下した後、この隙間32を通じて排水することができ(図中の矢印45参照)、室内側樹脂枠部12の上面に結露水が滞留するのを防止できる。
水密性や密閉性を重視する場合は、四周の室内側樹脂枠部11,12,13,14の突出片28の先端とガラス面31との間の隙間32を隙間塞ぎ材44で塞ぐこともできる。その場合でも、少なくとも一方の竪枠5又は6の下端部において、突出片28とガラス面31との間の隙間32を残存しておくことで、ガラス面31に生じた結露水をその隙間32を通じて排水することができる。

A gap 32 of about 3 mm is provided. The tip end portion 28a of the protruding piece 28 is made of a soft resin. This soft resin portion is provided by extrusion molding (so-called two-color molding) integrally with other hard resin portions.
By providing such indoor resin frame portions 11, 12, 13, and 14 on the inner periphery of the frame 1 on the indoor side, the folds 15, 16, and 17 of the shoji 2 are hidden from view from the indoor side. In addition, a space 33 having a narrow frontage and a deep depth is formed between the flanges 15, 16, and 17 of the shoji 2 and the indoor resin frame portions 11, 12, 13, and 14.
四周の室内側樹脂枠部11,12,13,14のうち下枠4の室内側樹脂枠部12は、図1に示すように、外周側部12aと内周側部12bとに分割して形成してある。このように下枠4の室内側樹脂枠部12を分割構造とすることで、オペレータハンドル22を取付けたり、オペレータハンドル22の動きをフリクションステー21bに伝える連動機構を設置したりするための加工が容易に行える。
また、図2に示すように、戸先側の竪枠6の室内側樹脂枠部14も、外周側部14aと内周側部14bとに分割して形成してある。本開口部建材は、オペレータハンドル22に替えて、障子2の戸先框17の室内側面にカムラッチハンドルを取付けることもでき、その場合は戸先側の竪枠6の室内側樹脂枠部14に切欠き加工等を行う必要があるが、室内側樹脂枠部14をこのように分割構造とすることで、加工が容易に行える。
The indoor resin frame 12 of the lower frame 4 among the four indoor resin frames 11, 12, 13, and 14 is divided into an outer peripheral portion 12a and an inner peripheral portion 12b as shown in FIG. It is formed. In this way, the interior side resin frame portion 12 of the lower frame 4 has a divided structure, so that processing for attaching the operator handle 22 or installing an interlocking mechanism for transmitting the movement of the operator handle 22 to the friction stay 21b is possible. Easy to do.
In addition, as shown in FIG. 2, the indoor side resin frame portion 14 of the door frame 6 on the door end side is also divided into an outer peripheral side portion 14a and an inner peripheral side portion 14b. In this opening construction material, instead of the operator handle 22, a cam latch handle can be attached to the indoor side surface of the door rod 17 of the shoji 2, and in that case, the indoor resin frame portion 14 of the door frame 6 on the door edge side. However, it is necessary to perform notch processing or the like, but by forming the indoor resin frame portion 14 in such a divided structure, the processing can be easily performed.
各室内側樹脂枠部11,12,13,14は、予め各金属枠部7,8,9,10に内周側から取付けられ、その上で上下枠3,4の金属枠部7,8の長手方向の端面を竪枠5,6の金属枠部9,10の内周側面に当接し、側方から挿入したネジを上下枠3,4の金属枠部7,8に形成されたタッピングホールに捩じ込んで、上下枠3,4と竪枠5,6を枠組みしている。
竪枠5,6の室内側樹脂枠部13,14と上下枠3,4の室内側樹脂枠部11,12の端部の納まりは、図3に示すように、いわゆる横勝ちの状態になっている。上下枠3,4の室内側樹脂枠部11,12の端部は、図5に示すように、突出片28に長手方向端部より竪框17から内周側に離間した位置まで達する切欠き34を設け、竪枠5,6の室内側樹脂枠部13,14は長手方向端部を直角に切断し、その切断した小口を上下枠3,4の室内側樹脂枠部11,12の内周側面35に当接している。そのため、竪枠5,6の室内側樹脂枠部13,14の突出片28は切欠き加工が不要であり、加工工数を削減できる。
図6は、上下枠3,4の室内側樹脂枠部11,12の端部の加工の他の例を示している。突出片28は、図6(b)に示すように、軟質樹脂で形成された先端部28aの室内外方向の長さが図5のものより長くなっており、また図6(a)に示すように、長手方向端部の突出片28の切欠き34を小さくすると共に、竪枠5,6の室内側樹脂枠部13,14の突出片28の外周側に隣接する位置で、突出片28に切り込み36を設けてある。このように突出片28に切り込み36を設けたことで、図6(c)に示すように、突出片28の左右の端部のみが障子2閉鎖時に変形するから、突出片28の障子2の竪框17と重合する部分を切除しなくても、障子2を閉鎖するのに支障がない。
Each indoor side resin frame portion 11, 12, 13, 14 is attached to each metal frame portion 7, 8, 9, 10 in advance from the inner peripheral side, and then the metal frame portions 7, 8 of the upper and lower frames 3, 4 are mounted thereon. The tapping formed on the metal frame portions 7 and 8 of the upper and lower frames 3 and 4 with the end faces in the longitudinal direction being in contact with the inner peripheral side surfaces of the metal frame portions 9 and 10 of the collar frames 5 and 6 The upper and lower frames 3 and 4 and the eaves frames 5 and 6 are framed by being screwed into the hole.
As shown in FIG. 3, the storage of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 and the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 is in a so-called horizontal winning state. ing. As shown in FIG. 5, the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 are notched so as to reach the projecting piece 28 from the longitudinal end portion to a position separated from the flange 17 toward the inner peripheral side. 34, and the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 are cut at the longitudinal ends at right angles, and the cut ends are formed inside the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4. It is in contact with the peripheral side surface 35. Therefore, the protruding pieces 28 of the indoor side resin frame portions 13 and 14 of the collar frames 5 and 6 do not need to be cut out, and the number of processing steps can be reduced.
FIG. 6 shows another example of processing of the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4. As shown in FIG. 6 (b), the protruding piece 28 has a length in the indoor / outdoor direction of the tip 28a formed of a soft resin longer than that in FIG. 5, and also shown in FIG. 6 (a). As described above, the notch 34 of the projecting piece 28 at the end in the longitudinal direction is reduced, and the projecting piece 28 is located at a position adjacent to the outer peripheral side of the projecting piece 28 of the indoor side resin frame parts 13, 14 of the collar frames 5, 6. An incision 36 is provided in FIG. Since the notches 36 are provided in the protruding piece 28 as described above, only the left and right end portions of the protruding piece 28 are deformed when the shoji 2 is closed as shown in FIG. There is no problem in closing the shoji 2 without excising the portion that overlaps with the scissors 17.
以上に述べたように本開口部建材は、枠1の室内側の内周部に室内側樹脂枠部11,12,13,14を設け、室内側樹脂枠部11,12,13,14は内周側面35に室外側に突出する突出片28を有し、突出片28は障子2の框15,16,17よりも内周側に位置していることで、障子2の框15,16,17が室内側樹脂枠部11,12,13,14で隠れるため、内観の見栄えが良い。さらに、突出片28の先端と障子2のガラス面31との間に隙間32が設けてあることで、図1に示すように、上框15やガラス面31等に生じた結露水37を、図中の矢印38a,38bで示すように、突出片28で堰き止めることなく流下させられ、下枠4上面(室内側樹脂枠部12の内周側面35)に結露水が滞留することがない。なお、流下した結露水は、下枠4と下框16とをシールしているタイト材25の上に滞留するが、障子2を開ければ室外に排水されるし、障子2を開けなくてもそのうちに蒸発してなくなる。
さらに本開口部建材は、室内側樹脂枠部11,12,13,14の突出片28により、障子2の框15,16,17と室内側樹脂枠部11,12,13,14との間に間口が狭く奥行の深い空間33を設けており、しかもその空間33の入り口部分33aがジグザグした形になっているため、アルミ製の框15,16,17を伝わる室外の冷気がこの空間33に滞留し、居住空間まで冷気が伝わりにくくなるため、断熱性能が向上する。また、暴風時にタイト材25を超えて噴出した雨水は、前記空間33を上昇するうちに運動エネルギーが低下して室内側に漏水しにくくなるので、水密性能も向上する。
また、室内側樹脂枠部11,12,13,14の突出片28の先端部28aを軟質樹脂で形成したことで、暴風時にガラス19が室内側に変形したり、障子2を乱暴に閉鎖したりしたときに、突出片28がガラス面31と接触したとしても、ガラス19の破損を防止することができ、前述の排水・断熱・水密性能をそのまま維持することができる。
突出片28は、框15,16,17の室内側壁の内周縁30から5〜10mm程度内周側に離間しているため、図4中に二点鎖線で示すように、障子2が開き始める際に障子2が戸先側にスライドしても、突出片28が戸尻側の竪框17と干渉することがなく、障子2の開閉が妨げられない。
さらに本開口部建材は、内観視で障子2の框15,16,17が見えないばかりか、室内側樹脂枠部11,12,13,14とガラス19との間に質感や色の異なるシール材が無いため、内観意匠をより一層向上することができる。
As described above, this opening building material is provided with the indoor resin frame portions 11, 12, 13, and 14 on the inner peripheral portion on the indoor side of the frame 1, and the indoor resin frame portions 11, 12, 13, and 14 are The inner peripheral side surface 35 has a protruding piece 28 that protrudes to the outdoor side, and the protruding piece 28 is located on the inner peripheral side with respect to the flanges 15, 16, and 17 of the shoji 2. , 17 are hidden by the indoor resin frame portions 11, 12, 13, and 14, so that the appearance of the interior is good. Furthermore, since the gap 32 is provided between the tip of the protruding piece 28 and the glass surface 31 of the shoji 2, as shown in FIG. 1, the dew condensation water 37 generated on the upper collar 15, the glass surface 31, etc. As indicated by arrows 38a and 38b in the figure, the projecting piece 28 is allowed to flow without damming, and dew condensation does not stay on the upper surface of the lower frame 4 (the inner peripheral side surface 35 of the indoor resin frame portion 12). . The condensed water that flows down stays on the tight material 25 that seals the lower frame 4 and the lower rod 16, but if the shoji 2 is opened, it is drained to the outside, and the shoji 2 is not opened. Over time it will not evaporate.
Further, the opening building material is provided between the flanges 15, 16, and 17 of the shoji 2 and the indoor resin frame portions 11, 12, 13, and 14 by the protruding pieces 28 of the indoor resin frame portions 11, 12, 13, and 14. Since the entrance 33a of the space 33 has a zigzag shape, the outdoor cold air transmitted through the aluminum cages 15, 16, and 17 is formed in the space 33. The heat insulation performance is improved because it is difficult to transmit cold air to the living space. In addition, rainwater spouted over the tight material 25 during a storm is less likely to leak into the room due to a decrease in kinetic energy as it rises in the space 33, so that watertightness is also improved.
Further, the tip portion 28a of the protruding piece 28 of the indoor side resin frame portions 11, 12, 13, 14 is formed of soft resin, so that the glass 19 is deformed indoors during a storm, or the shoji 2 is closed wildly. Even if the protruding piece 28 comes into contact with the glass surface 31 at the time, the glass 19 can be prevented from being damaged, and the above-mentioned drainage, heat insulation and watertight performance can be maintained as they are.
Since the projecting piece 28 is separated from the inner peripheral edge 30 of the indoor side wall of the flanges 15, 16, and 17 to the inner peripheral side by about 5 to 10 mm, the shoji 2 starts to open as shown by a two-dot chain line in FIG. Even when the shoji 2 slides to the door end side, the protruding piece 28 does not interfere with the heel 17 on the door bottom side, and the opening and closing of the shoji 2 is not hindered.
Furthermore, this building material for the opening portion not only shows the scissors 15, 16, 17 of the shoji 2 from the inside, but also seals with different textures and colors between the indoor resin frame portions 11, 12, 13, 14 and the glass 19. Since there is no material, the interior design can be further improved.
図7は、本発明の開口部建材の第2実施形態を示している。本実施形態は、竪枠5,6の室内側樹脂枠部13,14の形状が第1実施形態と異なっている。竪枠5,6の室内側樹脂枠部13,14は、内周側面42が室外側に向かうにつれて内周側に位置するように傾斜している。戸先側の竪枠6の室内側樹脂枠部14は、外周側部14aが第1実施形態と兼用である。
このように、内周側面42を傾斜させることで、竪枠5,6の室内側端部の見付寸法Aを小さくすることができ、内観意匠がさらに向上する。また、上下枠3,4と竪枠5,6とで室内側端部の見付寸法Aを共通にすることもできる。さらに、竪枠5,6の内周側面42とガラス面31との間の入隅部43が鈍角になるため、直角とした場合と比べて、入隅部43の拭き掃除が容易になる。
本実施形態においても、竪枠5,6の室内側樹脂枠部13,14と上下枠3,4の室内側樹脂枠部11,12の端部の納まりを、第1実施形態と同様に横勝ちの状態とすることで、竪枠5,6の室内側樹脂枠部13,14の内周側面42を傾斜させても、上下枠3,4の室内側樹脂枠部11,12の端部を斜めに切断する必要がなく、加工が容易である。
FIG. 7 shows a second embodiment of the opening building material of the present invention. In the present embodiment, the shapes of the indoor side resin frame portions 13 and 14 of the collar frames 5 and 6 are different from those of the first embodiment. The indoor side resin frame parts 13 and 14 of the eaves frames 5 and 6 are inclined so that the inner peripheral side surface 42 is positioned on the inner peripheral side as it goes to the outdoor side. As for the indoor side resin frame part 14 of the frame 6 on the door end side, the outer peripheral side part 14a is also used in the first embodiment.
Thus, by inclining the inner peripheral side surface 42, the finding dimension A of the indoor side ends of the collar frames 5 and 6 can be reduced, and the interior design is further improved. Further, the upper and lower frames 3, 4 and the eaves frames 5, 6 can have a common finding dimension A at the indoor side end. Furthermore, since the corner part 43 between the inner peripheral side surface 42 of the gutter frames 5 and 6 and the glass surface 31 becomes an obtuse angle, the wiping and cleaning of the corner part 43 is facilitated as compared with the case where it is a right angle.
Also in this embodiment, the storage of the end portions of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 and the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4 is the same as in the first embodiment. Even if the inner peripheral side surfaces 42 of the indoor side resin frame portions 13 and 14 of the eaves frames 5 and 6 are inclined by setting the winning state, the end portions of the indoor side resin frame portions 11 and 12 of the upper and lower frames 3 and 4. Is easy to process.
図8,9は、本発明の開口部建材の第3実施形態を示している。本実施形態のものは、障子2を枠1内に固定具(図示省略)で固定し、FIX窓としている。枠1と障子2は、第1実施形態のものと共通である。
下枠4の室内側樹脂枠部12の突出片28の先端とガラス面31との間の隙間32には、図8に示すように、ゴムや軟質樹脂で形成された隙間塞ぎ材44を内周側から挿入して取付けている。これにより、障子2を開閉できないFIX窓において、下枠4の室内側樹脂枠部12の突出片28の先端とガラス面31との間の隙間32に異物が落下して取り出しが困難となったり、意匠が低下したりするのを防ぐことができる。しかも、図9に示すように、竪枠5,6の室内側樹脂枠部13,14の突出片28の先端とガラス面31との間には隙間32があるため、ガラス面31に生じた結露水は隙間塞ぎ材44の上に落下した後、この隙間32を通じて排水することができ(図中の矢印45参照)、室内側樹脂枠部12の上面に結露水が滞留するのを防止できる。
水密性や密閉性を重視する場合は、四周の室内側樹脂枠部11,12,13,14の突出片28の先端とガラス面31との間の隙間32を隙間塞ぎ材44で塞ぐこともできる。その場合でも、少なくとも一方の竪枠5又は6の下端部において、突出片28とガラス面31との間の隙間32を残存しておくことで、ガラス面31に生じた結露水をその隙間32を通じて排水することができる。
8 and 9 show a third embodiment of the opening part building material of the present invention. The thing of this embodiment fixes the shoji 2 in the frame 1 with the fixing tool (illustration omitted), and makes it the FIX window. The frame 1 and the shoji 2 are the same as those in the first embodiment.
As shown in FIG. 8, a gap closing material 44 made of rubber or soft resin is placed in the gap 32 between the tip of the protruding piece 28 of the indoor side resin frame 12 of the lower frame 4 and the glass surface 31. Inserted from the circumferential side. Thereby, in the FIX window in which the shoji 2 cannot be opened and closed, foreign matter may fall into the gap 32 between the tip of the protruding piece 28 of the indoor side resin frame 12 of the lower frame 4 and the glass surface 31, making it difficult to take out. It is possible to prevent the design from deteriorating. Moreover, as shown in FIG. 9, since there is a gap 32 between the tip of the protruding piece 28 of the indoor side resin frame portions 13, 14 of the eaves frames 5, 6 and the glass surface 31, it occurred on the glass surface 31. After the condensed water falls on the gap plugging material 44, it can be drained through the gap 32 (see arrow 45 in the figure), and the condensed water can be prevented from staying on the upper surface of the indoor resin frame portion 12. .
When importance is attached to watertightness or airtightness, the gap 32 between the tips of the protruding pieces 28 of the four-side indoor resin frame portions 11, 12, 13, 14 and the glass surface 31 may be closed with a gap closing material 44. it can. Even in that case, by leaving the gap 32 between the protruding piece 28 and the glass surface 31 at the lower end of at least one of the frame 5 or 6, the condensed water generated on the glass surface 31 can be removed from the gap 32. Can be drained through.
本発明は以上に述べた実施形態に限定されない。障子は、横すべり出し式に室外側に開くものや、ヒンジで枠と連結されて室外側に開くものであってもよく、様々な開き方の窓とFIX窓との間で枠を兼用することができる。枠は、金属枠部と樹脂製の室内側枠部とで構成したものに限らず、金属枠部に相当する部分と室内側枠部に相当する部分を一体で形成したもの、例えば樹脂でこれらの部分を一体成型したものであってもよい。障子の框は、樹脂製であってもよい。
