図3に示すように、見込方向における、外側カバー3のカバー部材固定部33の端部と、固定部材側係合部12の立ち上がり部121との間には、隙間S1が形成されている。これにより、アンカー1の固定部材側係合部12が、内側縦枠24の縦枠見付延出部241-1及び縦枠見込延出部242-1を介して、気密材35を外側カバー3に対して押し付ける前に、カバー部材固定部33の端部と立ち上がり部121とが当接することを防ぐことが可能となる。このため、アンカー1の固定部材側係合部12が、内側縦枠24を介して気密材35を外側カバー3に対して確実に押し付けることが可能となる。
As shown in FIG. 3, a gap S1 is formed between the end portion of the cover member fixing portion 33 of the outer cover 3 and the rising portion 121 of the fixing member-side engaging portion 12 in the projection direction. As a result, the fixing-member-side engaging portion 12 of the anchor 1 engages the airtight material 35 via the vertical frame extension portion 241-1 and the vertical frame projection extension portion 242-1 of the inner vertical frame 24. It is possible to prevent the end portion of the cover member fixing portion 33 and the rising portion 121 from coming into contact with each other before being pressed against the cover member fixing portion 33 . Therefore, the fixing member-side engaging portion 12 of the anchor 1 can reliably press the airtight member 35 against the outer cover 3 via the inner vertical frame 24 .
また、図3に示すように、見込方向における、固定部材側係合部12の係合外方辺部123の端部と、内側縦枠24の縦枠見付延出部241-1との間には、隙間S2が形成されている。これにより、縦枠見込延出部242-1が固定部材側係合部12に係合する前に、係合外方辺部123の端部と縦枠見付延出部241-1とが当接することを防ぐことが可能となり、縦枠見込延出部242-1と固定部材側係合部12との係合を確実とすることが可能となる。
Further, as shown in FIG. 3, the end portion of the engaging outer side portion 123 of the fixing member side engaging portion 12 and the vertical frame extending portion 241-1 of the inner vertical frame 24 in the direction of projection. A gap S2 is formed between them. As a result, before the vertical frame projection extending portion 242-1 engages with the fixed member side engaging portion 12, the end portion of the engagement outer side portion 123 and the vertical frame projection extension portion 241-1 are aligned. Abutment can be prevented, and engagement between the vertical frame prospective extension portion 242-1 and the fixed member side engaging portion 12 can be ensured.
また、図3に示すように、左右方向における、外側カバー3のカバー部材固定部33、及び、連結部10の見込面と、固定部材側係合部12の係合片部122との間には、隙間S3が形成されている。これにより、固定部材側係合部12が連結部10及びカバー部材固定部33から左右方向に離間し、後述のように、内側縦枠24の縦枠見込延出部242-1を固定部材側係合部12に係合させる際に、当該係合を容易となる。
Further, as shown in FIG. 3, between the cover member fixing portion 33 of the outer cover 3, the projection surface of the connecting portion 10, and the engaging piece portion 122 of the fixing member side engaging portion 12 in the left-right direction. , a gap S3 is formed. As a result, the fixing member side engaging portion 12 is separated from the connecting portion 10 and the cover member fixing portion 33 in the left-right direction, and as described later, the vertical frame expected extension portion 242-1 of the inner vertical frame 24 is moved to the fixing member side. When engaging with the engaging portion 12, the engagement is facilitated.
固定部13は、固定部材側係合部12を有する板状部11の長手方向における一端部に対する板状部11の他端部から、板状部11の長手方向に直交するように延びる板状の部分であり、板状部11の他端部が折れ曲げられた形状を有している。固定部13は、図3に示すように、後述のように内側縦枠24が連結部10に沿って屋外側へ移動させられて、アンカー1に係合して連結部10に対して固定されたときに、連結部10の屋内側の端面である屋内側見付面に当接して、それ以上アンカー1が屋外側へ移動しないように、連結部10に対してアンカー1を移動不能とする。このため、アンカー1が屋外側へ向かって移動可能な範囲は、気密材35よりも屋内側の位置までであり、アンカー1と気密材35とは当接しないように構成されている。また、固定部13を屋内側へ引くことにより、内側縦枠24をアンカー1に固定する前の屋内側の位置に、アンカー1を容易に引き出すことが可能である。
The fixing portion 13 is a plate-like member extending perpendicularly to the longitudinal direction of the plate-like portion 11 from the other end of the plate-like portion 11 with respect to the one longitudinal end of the plate-like portion 11 having the fixing member-side engaging portion 12 . , and has a shape in which the other end portion of the plate-like portion 11 is bent. As shown in FIG. 3 , the fixing portion 13 is fixed to the connecting portion 10 by moving the inner vertical frame 24 along the connecting portion 10 to the outside and engaging with the anchor 1 as will be described later. The anchor 1 is made immovable with respect to the connecting part 10 so that the anchor 1 does not move further to the outdoor side by contacting the indoor side facing surface which is the end face of the indoor side of the connecting part 10 when the anchor 1 is closed. . Therefore, the range in which the anchor 1 can move toward the outdoor side is up to a position on the indoor side of the airtight material 35, and the anchor 1 and the airtight material 35 are configured so as not to come into contact with each other. Further, by pulling the fixing portion 13 toward the indoor side, the anchor 1 can be easily pulled out to the position on the indoor side before the inner vertical frame 24 is fixed to the anchor 1 .
図6は、屋内側アンカー7を示す正面図である。図7は、屋内側アンカー7を示す側面図である。
屋内側アンカー7は、図2に示すように、アンカー1とは別部材(別部品)で構成され、アンカー1の下側の連結部10の部分に固定されている。図3に示すように、屋内側アンカー7の固定部材屋内側係合部72は、アンカー1の固定部材側係合部12と共に内側縦枠24に被覆されている。従って、アンカー1の固定部材側係合部12及び屋内側アンカー7の固定部材屋内側係合部72は、内側縦枠24の外側へ露出していない。
また、枠体2の内側縦枠24の枠体側係合部240-1、枠体側係合部240-2と、これらに係合する固定部材側係合部12、固定部材屋内側係合部72は、連結部10の屋内側面と屋外側面の間にある。このため、見込方向において、枠体2の内側縦枠24の枠体側係合部240-1、枠体側係合部240-2と、これらに係合する固定部材側係合部12、固定部材屋内側係合部72は、連結部10の屋内側面よりも屋内側へ、及び、連結部10の屋外側面よりも屋外側へ突出していない。

図12等に示すように、アンカー1Aは、板状部11Aと、固定部材側係合部12Aと、固定部13Aと、を有する。
As shown in FIG. 12 and the like, the anchor 1A has a plate-like portion 11A, a fixing member-side engaging portion 12A, and a fixing portion 13A.
板状部11Aは、略長方形の板体であり、連結部10に取り付けられた状態で、連結部10の見込面に沿って延びるように配置される。板状部11Aにおける幅方向(図12における上下方向)における中央位置には、見込方向に一致する板状部11Aの長手方向に延びる長孔111Aが、板状部11Aの長手方向における中央を挟んで2つ形成されている。長孔111Aには、連結部10に固定されたネジが貫通する。
The plate-like portion 11A is a substantially rectangular plate, and is arranged so as to extend along the projected surface of the connecting portion 10 when attached to the connecting portion 10 . At the central position of the plate-like portion 11A in the width direction (vertical direction in FIG. 12), a long hole 111A extending in the longitudinal direction of the plate-like portion 11A, which coincides with the projection direction, sandwiches the center of the plate-like portion 11A in the longitudinal direction. Two are formed in . A screw fixed to the connecting portion 10 passes through the long hole 111A.
長孔111Aが形成されている板状部11Aの部分は、それぞれ段部112A、113Aを有している。段部112A、113Aは、長孔111Aの長手方向における中央位置の板状部11Aの部分に形成されており、この段部112A、113Aを堺として、板状部11Aの屋内側の部分は、板状部11Aの屋外側の部分に対して、連結部10に近い位置関係となるように構成されている。このため、段部112A、113Aを堺とした板状部11Aの屋内側の部分と連結部10との間には、図11に示すように、隙間が形成されている。段部112Aの屋内寄りの部分には、連結部10から離間するように突出する突起115Aが設けられている。従って、ネジが長孔111Aの長手方向において相対的に板状部11Aに対して長孔111A内を移動することにより、アンカー1Aは、連結部10に対して相対的に見込方向へ移動する。このとき、ネジが段部112Aによる段差の突起115Aに当接し、突起115Aよりも屋内側の板状部11Aの部分が、板状部11Aと連結部10との間に形成された隙間を縮めるようにして撓み、ネジが突起115Aを乗り越えることによりアンカー1Aが移動することになるため、突起115Aよりも屋内側に位置しているネジが、長孔111A内で相対的に移動することを防止し、意図せずアンカー1Aが屋外側へ移動して、アンカー1A及び下側アンカー7Aと、内側縦枠24と、の係合が解除されることを抑えることが可能である。
The portion of the plate-like portion 11A in which the long hole 111A is formed has stepped portions 112A and 113A, respectively. The stepped portions 112A and 113A are formed in the portion of the plate-shaped portion 11A at the central position in the longitudinal direction of the long hole 111A. It is configured to have a positional relationship close to the connecting portion 10 with respect to the outdoor portion of the plate-like portion 11A. Therefore, as shown in FIG. 11, a gap is formed between the connecting portion 10 and the indoor portion of the plate-like portion 11A with the stepped portions 112A and 113A as a boundary. A projection 115A that protrudes away from the connecting portion 10 is provided in a portion of the stepped portion 112A closer to the indoor side. Therefore, the anchor 1A moves in the projection direction relative to the connecting portion 10 by moving the screw in the long hole 111A relative to the plate-like portion 11A in the longitudinal direction of the long hole 111A. At this time, the screw abuts on the protrusion 115A of the stepped portion 112A, and the portion of the plate-like portion 11A on the indoor side of the protrusion 115A narrows the gap formed between the plate-like portion 11A and the connecting portion 10. Since the anchor 1A is moved by bending in this way and the screw climbs over the projection 115A, the screw located on the indoor side of the projection 115A is prevented from relatively moving within the long hole 111A. However, it is possible to prevent the anchor 1A from unintentionally moving to the outdoor side and releasing the engagement between the anchor 1A and the lower anchor 7A and the inner vertical frame 24. - 特許庁
