また、覆い部３０ａと垂設壁部３０ｃとがなす角度は、下枠１３の枠本体部１３ａの室内側の面と額縁当接部１３ｅの上面とがなす角度より僅かに小さく形成されている。例えば、下枠１３の枠本体部１３ａの室内側の面と額縁当接部１３ｅの上面とがなす角度が９０度であれば、覆い部３０ａと垂設壁部３０ｃとがなす角度は１度小さい８９度に形成されている。 Further, the angle formed by the cover portion 30a and the hanging wall portion 30c is formed slightly smaller than the angle formed by the surface on the indoor side of the frame main body portion 13a of the lower frame 13 and the upper surface of the frame contact portion 13e. . For example, if the angle formed by the indoor side surface of the frame main body portion 13a of the lower frame 13 and the upper surface of the frame contact portion 13e is 90 degrees, the angle formed by the cover portion 30a and the hanging wall portion 30c is 1 degree. It is formed at a small 89 degrees.

カバー部材３０の取り付けは、まず、下枠１３と方立１７とが溶着された後に、分断されている額縁当接部１３ｅの端部１３ｋ間を覆うように、覆い部３０ａの見付け方向における両端部３０ｈを額縁当接部１３ｅの端部１３ｋ上に載置し、垂設壁部３０ｃと延出部３０ｆとが分断された額縁当接部１３ｅの端部１３ｋ間に位置するように上方または室内側から配置する。 First, the cover member 30 is attached to both ends in the direction in which the cover portion 30a is located so that the space between the end portions 13k of the frame contact portion 13e that has been divided is covered after the lower frame 13 and the stand 17 are welded. The portion 30h is placed on the end portion 13k of the frame contact portion 13e, or the upper portion so that the hanging wall portion 30c and the extending portion 30f are positioned between the end portions 13k of the frame contact portion 13e. Arrange from the indoor side.

次に、垂設壁部３０ｃを枠本体部１３ａ側に押圧すると、係止片３０ｄは係止部１３ｈが設けられている溝部１３ｇに挿入されて、係止片３０ｄの先端に設けられた突起３０ｇが係止部１３ｈと係合して係止片３０ｄが係止される。このとき、覆い部３０ａと垂設壁部３０ｃとがなす角度は、下枠１３の枠本体部１３ａの室内側の面と額縁当接部１３ｅの上面とがなす角度より僅かに小さく形成されているので、覆い部３０ａと垂設壁部３０ｃとが開かれるようにカバー部材３０が弾性変形することにより、覆い部３０ａが額縁当接部１３ｅ側に付勢されて額縁当接部１３ｅの上面に押圧されるため、カバー部材３０が安定した状態で下枠１３に取り付けられる。 Next, when the hanging wall portion 30c is pressed toward the frame main body portion 13a, the locking piece 30d is inserted into the groove portion 13g provided with the locking portion 13h, and the protrusion provided at the tip of the locking piece 30d. 30g engages with the locking portion 13h, and the locking piece 30d is locked. At this time, the angle formed by the cover portion 30a and the hanging wall portion 30c is slightly smaller than the angle formed by the surface on the indoor side of the frame main body portion 13a of the lower frame 13 and the upper surface of the frame contact portion 13e. Therefore, when the cover member 30 is elastically deformed so that the cover portion 30a and the hanging wall portion 30c are opened, the cover portion 30a is urged toward the frame contact portion 13e and the upper surface of the frame contact portion 13e. Therefore, the cover member 30 is attached to the lower frame 13 in a stable state.

第１実施形態の窓ユニット１０によれば、一対の横枠としての上枠１２と下枠１３とに掛け渡して方立１７を取り付ける際に、上枠１２及び下枠１３に形成される切り込み部１３ｉは、額縁当接部１３ｅを分断して当該額縁当接部１３ｅより四周枠１１の外周側に至るように形成されているので、上枠１２及び下枠１３と方立１７とが溶着される溶着部分の長さをより長くすることが可能である。このため、十分な強度を備えた枠体２０を形成することが可能である。 According to the window unit 10 of the first embodiment, the notches formed in the upper frame 12 and the lower frame 13 when the vertical frame 17 is attached to the upper frame 12 and the lower frame 13 as a pair of horizontal frames. Since the part 13i is formed so as to divide the frame contact part 13e and reach the outer peripheral side of the four-frame 11 from the frame contact part 13e, the upper frame 12, the lower frame 13 and the stand 17 are welded. It is possible to make the length of the welded portion longer. For this reason, it is possible to form the frame 20 having sufficient strength.

また、上枠１２及び下枠１３に形成される切り込み部１３ｉを、額縁当接部１３ｅより四周枠１１の外周側に至るように形成することにより額縁当接部１３ｅが分断されたとしても、分断された額縁当接部１３ｅ間をカバー部材３０で覆うので、額縁当接部１３ｅの分断された部分においても額縁当接部１３ｅと同様に額縁１８が当接される部位を設けることが可能である。そして、カバー部材３０が額縁当接部１３ｅ間を覆うことにより額縁１８と枠本体部１３ａとの境界部分を、窓ユニット１０における見付け方向の全域に渡って覆うことが可能であり、また、額縁当接部１３ｅの分断された端部１３ｋをカバー部材３０にて覆うことが可能である。このため、額縁当接部１３ｅを備えた上枠１２及び下枠１３に、額縁当接部１３ｅより四周枠１１の外周側に至るような切り込み部１３ｉを形成して方立１７を溶着しても美観に優れている窓ユニット１０を提供することが可能である。 Further, even if the frame contact portion 13e is divided by forming the cut portions 13i formed in the upper frame 12 and the lower frame 13 so as to reach the outer peripheral side of the four-frame 11 from the frame contact portion 13e, Since the divided frame contact portion 13e is covered with the cover member 30, it is possible to provide a portion where the frame 18 is in contact with the divided portion of the frame contact portion 13e as well as the frame contact portion 13e. It is. The cover member 30 covers the frame contact portion 13e so that the boundary portion between the frame 18 and the frame main body portion 13a can be covered over the entire area of the window unit 10 in the finding direction. The divided end portion 13k of the contact portion 13e can be covered with the cover member 30. For this reason, in the upper frame 12 and the lower frame 13 provided with the frame contact portion 13e, a cut portion 13i extending from the frame contact portion 13e to the outer peripheral side of the four-frame 11 is formed, and the vertical 17 is welded. It is possible to provide the window unit 10 which is also excellent in aesthetics.

また、カバー部材３０は覆い部３０ａを、分断された額縁当接部１３ｅ間に四周枠１１の内周側からから掛け渡して係止片３０ｄを係止部１３ｈに係止するだけで、カバー部材３０を容易に取り付けることが可能である。 Further, the cover member 30 is configured to cover the cover portion 30a from the inner peripheral side of the four-frame frame 11 between the divided frame contact portions 13e and lock the locking piece 30d to the locking portion 13h. The member 30 can be easily attached.

また、カバー部材３０は樹脂製なので弾性変形しやすく、係止片３０ｄが係止部１３ｈに係止されると、当該カバー部材３０の弾性により覆い部３０ａが額縁当接部１３ｅ側に付勢されることにより覆い部３０ａの額縁当接部１３ｅと重なる部位が額縁当接部１３ｅに押圧されるので、覆い部３０ａと額縁当接部１３ｅとが密着して安定した状態でカバー部材３０を取り付けることが可能である。 Further, since the cover member 30 is made of resin, it is easily elastically deformed. When the locking piece 30d is locked to the locking portion 13h, the cover portion 30a is urged toward the frame contact portion 13e by the elasticity of the cover member 30. As a result, the portion of the cover portion 30a that overlaps the frame contact portion 13e is pressed by the frame contact portion 13e, so that the cover member 30 can be held in a stable state with the cover portion 30a and the frame contact portion 13e being in close contact. It is possible to attach.

上枠１２、下枠１３、及び左右の縦枠１４、１５は、いずれも樹脂製なので溶着し易く仕上がりがきれいなので、容易に形成可能で、かつ、より美観に優れた窓ユニット１０を提供することが可能である。 Since the upper frame 12, the lower frame 13, and the left and right vertical frames 14 and 15 are all made of resin, they are easy to weld and have a beautiful finish. Therefore, the window unit 10 can be easily formed and has a more beautiful appearance. It is possible.

第２実施形態の窓ユニット１０においても、図１に示すように、上枠１２、下枠１３、及び左右の縦枠１４、１５の両端部が斜めに切断されて互いに突き合わされて溶着された四周枠１１の上枠１２と下枠１３に、額縁当接部１３ｅより四周枠１１の外周側に至るように形成された切り込み部１３ｉに方立１７が溶着されている構成は、上記第１実施形態と同様である。以下の説明においては、上記第１実施形態と同様の部材には同符号を付して、その説明を省略する。また、第２実施形態においても、下枠１３と方立１７との接合部について説明する。 Also in the window unit 10 of the second embodiment, as shown in FIG. 1, both ends of the upper frame 12, the lower frame 13, and the left and right vertical frames 14, 15 are cut obliquely and abutted with each other to be welded. The configuration in which the stand 17 is welded to the upper frame 12 and the lower frame 13 of the four-circumferential frame 11 and the cut portion 13i formed so as to reach the outer peripheral side of the four-circumferential frame 11 from the frame contact portion 13e This is the same as the embodiment. In the following description, the same members as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Moreover, also in 2nd Embodiment, the junction part of the lower frame 13 and the vertical 17 is demonstrated.

第２実施形態の方立１７には、図４に示すように、先端が９０度になるように切断された部位の見付け方向における中央に、第２実施形態のカバー部材３２を取り付けるための見込み方向に貫通する開孔としての嵌合孔１７ｄが設けられている。 As shown in FIG. 4, the vertical member 17 of the second embodiment has a prospect for attaching the cover member 32 of the second embodiment to the center in the direction of finding the portion cut so that the tip is 90 degrees. A fitting hole 17d is provided as an opening that penetrates in the direction.

第２実施形態のカバー部材３２は、図５、図６に示すように、分断された額縁当接部１３ｅの端部１３ｋ間に掛け渡されて、見付け方向の両端部３２ｆが分断された額縁当接部１３ｅの端部１３ｋにそれぞれ載置される覆い部３２ａと、覆い部３２ａの室外側の縁から上方に立設された立設壁部３２ｂと、立設壁部３２ｂの室外側の面から突出された嵌合片３２ｃと、覆い部３２ａの室内側の縁から額縁当接部１３ｅの厚みとほぼ同じ長さだけ下方に延出された延出部３２ｄとを有している。ここで、立設壁部３２ｂは、額縁当接部１３ｅの基端側としての室外側の縁から覆い部３２ａと交差する方向であって四周枠１１の内周側に延出された内側延出部の一例に相当する。 As shown in FIGS. 5 and 6, the cover member 32 according to the second embodiment is spanned between the end portions 13 k of the divided frame contact portion 13 e, and the frame portion in which both end portions 32 f in the finding direction are divided. A cover portion 32a that is respectively placed on the end portion 13k of the contact portion 13e, a standing wall portion 32b that is erected upward from an outdoor edge of the cover portion 32a, and an outdoor portion of the standing wall portion 32b. It has a fitting piece 32c protruding from the surface, and an extending portion 32d extending downward from the indoor side edge of the cover portion 32a by a length substantially equal to the thickness of the frame contact portion 13e. Here, the standing wall portion 32b extends from the outdoor side edge as the base end side of the frame contact portion 13e to the inner peripheral side of the quadrilateral frame 11 in a direction intersecting the cover portion 32a. It corresponds to an example of a protruding part.

立設壁部３２ｂは、見付け方向における覆い部３２ａの幅のほぼ半分であり、見付け方向において覆い部３２ａの中央に設けられ、枠体２０に取り付けられた際に方立１７に設けられた嵌合孔１７ｄを室内側から覆うように形成されている。 The standing wall portion 32b is approximately half the width of the cover portion 32a in the direction of finding, and is provided in the center of the cover portion 32a in the direction of finding and is provided in the vertical 17 when attached to the frame body 20. The joint hole 17d is formed so as to cover from the indoor side.

嵌合片３２ｃは、立設壁部３２ｂから室外側に向かって突出され、見付け方向に互いに間隔を隔てて配置された対をなす部材であり、嵌合片３２ｃの先端には、嵌合片３２ｃが嵌合孔１７ｄに挿入されて係止される係止突部３２ｅが、対をなす嵌合片３２ｃが対向する側とは反対方向に向かって突出されている。 The fitting piece 32c is a member that protrudes from the standing wall portion 32b toward the outdoor side and forms a pair that is spaced apart from each other in the finding direction. A locking protrusion 32e that is inserted and locked into the fitting hole 17d protrudes in a direction opposite to the opposite side of the paired fitting pieces 32c.

また、覆い部３２ａと立設壁部３２ｂとがなす角度は、下枠１３の枠本体部１３ａの室内側の面と額縁当接部１３ｅの上面とがなす角度より僅かに大きく形成されている。例えば、下枠１３の枠本体部１３ａの室内側の面と額縁当接部１３ｅの上面とがなす角度が９０度であれば、覆い部３２ａと立設壁部３２ｂとがなす角度は１度大きい９１度に形成されている。 Further, the angle formed by the cover portion 32a and the standing wall portion 32b is formed slightly larger than the angle formed by the surface on the indoor side of the frame main body portion 13a of the lower frame 13 and the upper surface of the frame contact portion 13e. . For example, if the angle formed by the indoor side surface of the frame main body portion 13a of the lower frame 13 and the upper surface of the frame contact portion 13e is 90 degrees, the angle formed by the cover portion 32a and the standing wall portion 32b is 1 degree. It is formed at a large 91 degrees.

カバー部材３２の取り付けは、まず、下枠１３と方立１７とが溶着された後に、分断されている額縁当接部１３ｅの端部１３ｋ間を覆うように覆い部３２ａの見付け方向における両端部３２ｆを、額縁当接部１３ｅの端部１３ｋ上に載置し、延出部３２ｄが分断された額縁当接部１３ｅの端部１３ｋ間に位置するように上方または室内側から配置する。 First, the cover member 32 is attached to both end portions in the direction in which the cover portion 32a is located so as to cover the space between the end portions 13k of the frame contact portion 13e that is divided after the lower frame 13 and the vertical 17 are welded. 32f is placed on the end portion 13k of the frame contact portion 13e, and is arranged from above or from the indoor side so that the extended portion 32d is located between the end portions 13k of the frame contact portion 13e.

次に、立設壁部３２ｂを下枠１３側に押圧すると、嵌合片３２ｃは方立１７に設けられている嵌合孔１７ｄに挿入されて、嵌合片３２ｃの先端に設けられた係止突部３２ｅが嵌合孔１７ｄと係合して嵌合片３２ｃか係止される。このとき、覆い部３２ａと立設壁部３２ｂとがなす角度は、下枠１３の室内側横壁部１３ｂの室内側の面と額縁当接部１３ｅの上面とがなす角度より僅かに大きく形成されているので、覆い部３２ａと立設壁部３２ｂとが圧縮されるようにカバー部材３２が弾性変形することにより、覆い部３２ａが額縁当接部１３ｅ側に付勢されて額縁当接部１３ｅの上面に押圧されるため、カバー部材３２が安定した状態にて枠体２０に取り付けられる。 Next, when the standing wall portion 32b is pressed to the lower frame 13 side, the fitting piece 32c is inserted into the fitting hole 17d provided in the vertical 17 and the engagement provided at the tip of the fitting piece 32c. The stop protrusion 32e engages with the fitting hole 17d and the fitting piece 32c is locked. At this time, the angle formed by the cover portion 32a and the standing wall portion 32b is slightly larger than the angle formed by the indoor side surface of the indoor side horizontal wall portion 13b of the lower frame 13 and the upper surface of the frame contact portion 13e. Therefore, when the cover member 32 is elastically deformed so that the cover portion 32a and the standing wall portion 32b are compressed, the cover portion 32a is urged toward the frame contact portion 13e and the frame contact portion 13e. Therefore, the cover member 32 is attached to the frame body 20 in a stable state.

第２実施形態の窓ユニット１０によれば、第１実施形態と同様に、溶着部分の長さが長く、十分な強度を備え、分断された額縁当接部１３ｅ間を覆い部３２ａにて覆って額縁当接部１３ｅの分断された端部１３ｋが露出しない美観に優れた窓ユニット１０を提供することが可能である。 According to the window unit 10 of the second embodiment, similarly to the first embodiment, the length of the welded portion is long, the strength is sufficient, and the divided frame contact portion 13e is covered with the cover portion 32a. Thus, it is possible to provide the window unit 10 having an excellent aesthetic appearance in which the divided end portion 13k of the frame contact portion 13e is not exposed.

また、カバー部材３２は樹脂製なので、嵌合片３２ｃが弾性変形しやすいカバー部材３２を形成することが可能であり、カバー部材３２を容易に取り付けることが可能である。また、上枠１２、下枠１３、及び左右の縦枠１４、１５は、いずれも樹脂製なので溶着し易く仕上がりがきれいなので、容易に形成可能で、かつ、より美観に優れた窓ユニット１０を提供することが可能である。 Further, since the cover member 32 is made of resin, the cover member 32 can be formed so that the fitting piece 32c is easily elastically deformed, and the cover member 32 can be easily attached. Further, since the upper frame 12, the lower frame 13, and the left and right vertical frames 14, 15 are all made of resin, they are easy to weld and have a beautiful finish. Therefore, the window unit 10 can be easily formed and has a more beautiful appearance. It is possible to provide.

さらに、カバー部材３２は、覆い部３２ａの長手方向の端部３２ｆが、四周枠１１の内周側にて、分断された額縁当接部１３ｅ間に掛け渡され、額縁当接部１３ｅの基端側から四周枠１１の内周側に延出された立設壁部３２ｂが有する嵌合片３２ｃが、方立１７に設けられた見込み方向に貫通する嵌合孔１７ｄに挿入されて係止突部３２ｅが係止されるので、覆い部３２ａを分断された額縁当接部１３ｅ間に四周枠１１の内周側から掛け渡すとともに、そのまま方立１７側に押圧してカバー部材３２を嵌合孔１７ｄに係止することが可能である。このため、カバー部材３２を容易に取り付けることが可能である。 Further, the cover member 32 has a longitudinal end portion 32f of the cover portion 32a spanned between the divided frame contact portions 13e on the inner peripheral side of the four-sided frame 11, and the base of the frame contact portion 13e. A fitting piece 32c of a standing wall portion 32b extending from the end side to the inner circumferential side of the four-frame 11 is inserted into a fitting hole 17d that penetrates in a prospective direction provided in the vertical 17 and is locked. Since the protrusion 32e is locked, the cover 32a is spanned from the inner periphery side of the four-frame 11 between the divided frame contact portions 13e, and the cover member 32 is fitted by pressing it toward the side 17 as it is. It is possible to lock in the joint hole 17d. For this reason, it is possible to attach the cover member 32 easily.
