MODIFIED SASH

PROBLEM TO BE SOLVED: To provide a modified sash, which enables a new sill to be installed in response to a step between an indoor section and an outdoor section of an existing sill in vertical direction.SOLUTION: A modified sash has an existing sill 12 and a new sill 22. A sill support fitting 50 is disposed between these sills. The sill support fitting 50 has a bearing member 51 and an adjustment member 61. The adjustment member 61 can be switched between a first fitting state and a second fitting state. In the first fitting state, a short side of the adjustment member is fitted to a fitting piece 53 of the bearing member 51 in a first fitting direction to abut against the existing sill 12 so as to be position-adjustable in vertical direction, while in the second fitting state, a long side 612 of the adjustment member is fitted to the fitting piece 53 in a second fitting direction to abut against the existing sill 12 so as to be position-adjustable in vertical direction. A maximum dimension from a lower side of the fitting piece 53 in the first fitting state to the short side is longer than a maximum dimension L3 from the lower side of the fitting piece 53 in the second fitting state to the long side 612.SELECTED DRAWING: Figure 3 【課題】既設下枠の室内部分と室外部分との上下方向における段差に対応して新設下枠を設置できる改装サッシを提供すること。【解決手段】改装サッシは、既設下枠１２と新設下枠２２とを備え、これらの間には下枠支持金具５０が配置される。下枠支持金具５０は、支持部材５１と調整部材６１とを備える。調整部材６１は、その短辺が既設下枠１２に当接する第一取付向きで支持部材５１の取付片部５３に上下方向に位置調整可能に取り付けられる第一取付状態と、その長辺６１２が既設下枠１２に当接する第二取付向きで取付片部５３に上下方向に位置調整可能に取り付けられる第二取付状態とを切替え可能に構成される。第一取付状態における取付片部５３の下辺から短辺までの最大寸法は、第二取付状態における取付片部５３の下辺から長辺６１２までの最大寸法Ｌ３よりも長い寸法とされる。【選択図】図３
