SASH STRUCTURE FOR CONSTRUCTION MACHINE CABIN
To provide a sash structure for construction machine cabin capable of expanding a visual field of a double sliding window.SOLUTION: A sash structure for cabin includes: a double sliding window frame 5 disposed in a cabin 1; and a plurality of movable window members 6a, 6b provided at the double sliding window frame 5 so as to slide in the forward/backward direction, and provided overlapped in the inside/outside direction of the cabin 1. At the double sliding window frame 5, a plurality of fitting grooves 16a, 16b fitted in the movable window members 6a, 6b is formed overlapped in the inside/outside direction of the cabin 1, and a plurality of groove wall parts 17a, 17b, 17c for partitioning and forming these fitting grooves 16a, 16b is formed extending to the inner peripheral side of the double sliding window frame 5, and extension length L1 of the groove wall part 17c on the outdoor side is set to be shorter than extension length L2 of the groove wall part 17b on the indoor side.SELECTED DRAWING: Figure 3
【課題】引き違い窓の視界を拡大できる建設機械のキャビン用サッシュ構造を提供する。【解決手段】キャビン用サッシュ構造は、キャビン１に配設された引き違い窓枠５と、引き違い窓枠５に前後方向に摺動自在に設けられると共にキャビン１の内外方向に重ねて設けられる複数の可動窓部材６ａ、６ｂとを備え、引き違い窓枠５には、可動窓部材６ａ、６ｂと嵌合される嵌合溝１６ａ、１６ｂがキャビン１の内外方向に重ねて複数形成されると共に、これら嵌合溝１６ａ、１６ｂを区画形成するための溝壁部１７ａ、１７ｂ、１７ｃが引き違い窓枠５の内周側に延出して複数形成され、室外側の溝壁部１７ｃの延出長さＬ１が、室内側の溝壁部１７ｂの延出長さＬ２より短くなるように設定される。【選択図】図３
