Description

本発明は、建物に設ける段窓用のサッシに関する。   The present invention relates to a sash for a corrugated window provided in a building.

従来より、段窓用のサッシは、上窓の下枠と下窓の上枠が無目に対してネジ等により固着されて組付けられた後、無目と上下の窓とで形成される連結部の凹溝にコーキング材を充填するか、パッキングを嵌着して連結部からの雨水の浸入を防止していた。
また、無目と下窓とをその室内側部分において固定ネジで連結固定するとともに、無目と下窓の室外側においてパッキングを挟持して、無目と上下の窓とで形成される連結部の凹溝をパッキングにより被覆してシールして雨水の浸入を防止していた。 Conventionally, a sash for a corrugated window is formed by an upper window and a lower window after the lower frame of the upper window and the upper frame of the lower window are fixed and assembled to the invisible by screws or the like. Caulking material is filled into the concave groove of the connecting portion or a packing is fitted to prevent intrusion of rainwater from the connecting portion.
In addition, the joint and the lower window are connected and fixed with a fixing screw at the indoor side portion, and the packing is sandwiched between the joint and the lower window on the outdoor side, and the connection portion is formed by the eyes and the upper and lower windows. The groove was covered with a packing and sealed to prevent rainwater from entering.

しかしながら、無目と上下の窓とで形成される連結部の凹溝にコーキング材を充填するか、パッキングを嵌着する構成では、コーキングやパッキンの施工不良や経年劣化によりシール性が損なわれて枠内に雨水の浸入が発生したり、雨水の侵入を防止するために無目が下窓の室外側面に露出する構成となってしまい、外観を損ねる等の難点があった。
また、無目と下窓の上枠の室外側においてパッキングを挟持して、無目と上下の窓とで形成される連結部の凹溝をパッキングにより被覆する構成でも、無目と下窓の上枠とが上下方向にパッキングを挟持した状態で連結固定されているので、パッキングの経年劣化による縮み等により無目と上枠との間に上下方向のがたつきが生じ、パッキングと上枠との間から上枠内に雨水が侵入する可能性があった。 However, in a configuration in which caulking material is filled in the concave groove of the connecting portion formed by the seamless and upper and lower windows, or the packing is fitted, the sealing performance is impaired due to poor caulking or packing construction or deterioration over time. There is a problem that rainwater intrudes into the frame or that the invisible eyes are exposed to the outdoor side surface of the lower window in order to prevent rainwater from entering, and the appearance is impaired.
In addition, the packing is sandwiched outside the upper frame of the upper frame of the magenta and the lower window, and the groove of the connecting portion formed by the magenta and the upper and lower windows is covered with the packing. Since the upper frame and the upper frame are connected and fixed with the packing sandwiched in the vertical direction, there is a backlash in the vertical direction between the eyes and the upper frame due to shrinkage due to aging of the packing, etc. Rainwater could enter the upper frame from between.

（連結構造）
上窓の下枠、下窓の上枠及び無目の連結構造について説明する。
下窓２の上枠２１に対して、室内側の斜め上方より無目３の係止部３３が下窓２の上枠２１の係合溝２１２ｂに挿入され、その後、下窓２の上枠２１の室内側見付け壁２１１の上端に形成された室内側屈曲部２１１ａが無目３の本体部３２の下面板部３２ｂ下面の第３突起部３２ｆと固定板部３１により形成される係合溝３２ｈ内に配置されながら無目３が下窓２の上枠２１上に載置される。 (Linked structure)
The lower frame of the upper window, the upper frame of the lower window, and the seamless connection structure will be described.
With respect to the upper frame 21 of the lower window 2, an invisible 3 locking portion 33 is inserted into the engagement groove 212 b of the upper frame 21 of the lower window 2 from the diagonally upper side on the indoor side. The engagement groove formed by the third protrusion 32f on the lower surface of the lower surface plate portion 32b of the body 3 and the fixed plate portion 31 is formed in the indoor side bent portion 211a formed at the upper end of the 21 indoor side finding wall 211. The invisible eye 3 is placed on the upper frame 21 of the lower window 2 while being arranged within 32h.

このように、無目３の室外側に形成された係止部３３が下窓２の上枠２１に形成された係合溝２１２ｂに挿入されることにより係合溝２１２ｂを構成する第２水平部２１３ｃが下窓２の上枠２１の浮き上がり防止部として作用して上下方向のふらつきが防止できる。   As described above, the engaging portion 33 formed on the outer side of the seamless 3 is inserted into the engaging groove 212b formed on the upper frame 21 of the lower window 2, whereby the second horizontal that forms the engaging groove 212b. The part 213c acts as a floating prevention part of the upper frame 21 of the lower window 2 and can prevent vertical fluctuation.

また、無目３の係止部３３が係合溝２１２ｂに挿入されると、無目３の係止部３３のタイト材取付溝３３ｂに装着されたタイト材４が室外側屈曲部２１２ａと無目３の延設部３３ａとに挟まれてその弾性により無目３が室内側に付勢されるが、無目３の第３突起部３２ｆが下窓２の上枠２１の室内側屈曲部２１１ａの先端に当接して無目３が下窓２の上枠２１に対して位置決めされて室内外方向の移動が阻止されるので、接続作業を容易にすることができるとともに、タイト材４による水密がなされる。   When the seamless engagement portion 33 is inserted into the engagement groove 212b, the tight material 4 attached to the tight material mounting groove 33b of the seamless connection portion 33 is not connected to the outdoor bending portion 212a. The intermittence 3 is sandwiched between the extension portions 33a of the eyes 3 and is elastically urged to the indoor side by the elasticity thereof, but the third protrusion 32f of the intangible 3 is the inwardly bent portion of the upper frame 21 of the lower window 2. 211a is brought into contact with the front end of the lower window 2 and is positioned with respect to the upper frame 21 of the lower window 2 to prevent movement in the indoor / outdoor direction. Watertight.

さらに、無目３の固定板部３１と下窓２の上枠２１の室内側見付け壁２１１とがネジ５により連結固定されネジ締めされることにより、下窓２の上枠２１の室外側屈曲部２１２ａと無目３の延設部３３ａの室外側面との距離が狭まり、タイト材４が室外側屈曲部２１２ａの先端と無目の室外側面とでさらに押し潰されて下窓２の上枠２１と無目３の間の水密を良好とすることができる。
なお、上記の例では、無目３を下窓２の上枠２１に設置することによってある程度の水密がなされるように無目３の第３突起部３２ｆの位置が設定されているが、第３突起部３２ｆは必ずしも必要なものではなく、また、その位置も特に限定されるものではなく、無目３を下窓２の上枠２１に載置した後に無目３の固定板部３１と下窓２の上枠２１の室内側見付け壁２１１とがネジ５によりネジ締めされることによって、タイト材４が室外側屈曲部２１２ａの先端と無目の室外側面とで押し潰されて、タイト材４による水密がなされるように構成しても良い。 Further, the indirect bending of the upper frame 21 of the upper window 21 of the lower window 2 is achieved by connecting and fixing the fixed plate portion 31 of the seamless 3 and the indoor side finding wall 211 of the upper frame 21 of the lower window 2 with screws 5. The distance between the portion 212a and the outdoor side surface of the extension portion 33a of the seamless 3 is narrowed, and the tight material 4 is further crushed by the tip of the outdoor bending portion 212a and the seamless outdoor side surface of the lower window 2 The watertightness between 21 and the seamless 3 can be improved.
In the above example, the position of the third protrusion 32f of the seamless 3 is set so that a certain degree of watertightness is achieved by installing the seamless 3 on the upper frame 21 of the lower window 2. The three projecting portions 32f are not necessarily required, and the position thereof is not particularly limited. After placing the eyeless 3 on the upper frame 21 of the lower window 2, the fixing plate portion 31 of the eyeless 3 When the indoor-side finding wall 211 of the upper frame 21 of the lower window 2 is screwed with the screw 5, the tight material 4 is crushed by the tip of the outdoor bent portion 212a and the invisible outdoor side surface, and tight. You may comprise so that the watertight by the material 4 may be made.

そして、無目３の上に上窓１の下枠１２を載置し、無目３の固定板部３１と上窓１の下枠１２の室内側見付け壁１２１とをネジ５により固定すると共に、無目３の本体部３２の室外側面部３２ｃと上窓１の下枠１２の連結片１２３ｆとをネジ５により固定している。この際、上窓１の下枠１２のアンカー係止部に無目３の上面板部３２ａに設けられた第１突起部３２ｄ及び第２突起部３２ｅが配置されるので、無目３と上窓１の下枠１２との位置決めが容易となる。   Then, the lower frame 12 of the upper window 1 is placed on the mesh 3, and the fixing plate portion 31 of the mesh 3 and the indoor side finding wall 121 of the lower frame 12 of the upper window 1 are fixed with the screws 5. The outdoor side surface portion 32 c of the body portion 32 of the seamless 3 and the connecting piece 123 f of the lower frame 12 of the upper window 1 are fixed by screws 5. At this time, since the first protrusion 32d and the second protrusion 32e provided on the upper surface plate portion 32a of the seamless 3 are arranged at the anchor locking portion of the lower frame 12 of the upper window 1, Positioning with the lower frame 12 of the window 1 becomes easy.

上記のように、枠体に設けられているアンカー係止部を利用して無目３に対して位置決めして連結固定ができるとともに、タイト材４による水密を図ることができるので、窓単体として建物の開口部に用いられていた窓を段窓として構成する際に特別な加工が必要とならず、施工が容易である。   As described above, the anchor locking portion provided on the frame body can be used for positioning and fixing with respect to the joint 3 and the water tightness by the tight material 4 can be achieved. When the window used in the opening of the building is configured as a step window, no special processing is required, and construction is easy.

上窓１の下枠１２の室外側支持部１２３の水平片１２３ｅと無目３の延設部３３ａとの間には、上窓１の下枠１２の連結片１２３ｆと無目３の室外側面部３２ｃとの連結部を底部とする室外側に開口する溝が形成され、溝の底部にはバックアップ材７が配置されると共に、溝内にコーキング材８が充填されて、無目３と上下の窓１，２の間から雨水等が浸入することを防止している。   Between the horizontal piece 123e of the outdoor side support part 123 of the lower frame 12 of the upper window 1 and the extension part 33a of the seamless window 1, the connecting piece 123f of the lower frame 12 of the upper window 1 and the outdoor side surface of the seamless pattern 3 are provided. A groove that is open to the outside of the room with the connecting portion with the portion 32c as the bottom is formed, and the back-up material 7 is disposed at the bottom of the groove, and the caulking material 8 is filled in the groove, so Rain water etc. is prevented from entering between the windows 1 and 2.

以上のように、本発明の実施形態のサッシは、無目３の室外側端部に形成された係止部３３を下窓２の上枠２１の室外側に設けた室外側屈曲部２１２ａと浮き上がり防止片２１２ｃとにより形成される係合溝２１２ｂに挿入して固定するので、無目３の室外側が上下方向にふらつくことがない。
また、無目３の係止部３３を室外側壁面から露出させる必要がないので段窓の室外側を面一にすることができ意匠性がよい。
さらに、無目３の固定板部３１を下窓２の上枠２１の室内側見付け壁２１１に室内側からネジ５により接合して締め付けることによって、無目３の係止部３３に設けられたタイト材４が下窓２の上枠２１の室外側屈曲部２１２ａと無目３の延設部３３ａとによって押し潰されて水密することができ、無目と上下の窓とで形成される連結部の溝内に充填されるコーキング材の施工不良があっても漏水の可能性を低く抑えることができる。 -Actions and effects according to embodiments of the present invention-
As described above, the sash according to the embodiment of the present invention includes the outdoor bent portion 212a provided with the engaging portion 33 formed on the outdoor end of the seamless window 3 on the outdoor side of the upper frame 21 of the lower window 2. Since it is inserted and fixed in the engagement groove 212b formed by the floating prevention piece 212c, the outdoor side of the intangible 3 does not fluctuate in the vertical direction.
Further, since it is not necessary to expose the seamless engaging portion 33 from the wall surface on the outdoor side, the outdoor side of the step window can be made flush and the design is good.
Further, the fixing plate portion 31 of the seamless 3 is provided on the locking portion 33 of the seamless 3 by joining and tightening the screw 5 to the indoor-side finding wall 211 of the upper frame 21 of the lower window 2 from the indoor side. The tight material 4 can be crushed by the outdoor bent portion 212a of the upper frame 21 of the lower window 2 and the extending portion 33a of the seamless 3 to be watertight, and the connection formed by the seamless and the upper and lower windows. Even if there is a poor construction of the caulking material filled in the groove of the part, the possibility of water leakage can be kept low.

なお、上記第１及び第２の実施形態においては、係合溝２１２ｂを形成する屈曲部として下窓２の上枠２１のアンカー係止部の一部となる室外側屈曲部２１２ａを利用しているが、屈曲部をアンカー係止部とは関係なく別に設けてもよい。   In the first and second embodiments, the outdoor bent portion 212a that is a part of the anchor locking portion of the upper frame 21 of the lower window 2 is used as the bent portion that forms the engaging groove 212b. However, the bent portion may be provided independently of the anchor locking portion.
