WINDOW OPENING/CLOSING DEVICE AND WINDOW

PROBLEM TO BE SOLVED: To provide a window opening/closing device which has simplified a mechanism for interlockingly performing opening/closing of sliding screens and locking/unlocking of a lock.SOLUTION: A window opening/closing device includes: a sliding screen opening/closing mechanism 42 for performing opening/closing operation of sliding screens 1, 1 supported in a frame 16 in an openable/closable manner; a lock part 43 for locking the sliding screens 1, 1 in a closed state; a chain-like body 44 arranged striding over a vertical frame 5 and a horizontal frame 14, and for connecting the sliding screen opening/closing mechanism 42 and the lock part 43 in an interlocked manner; and a chain-like body driving part 45 arranged at a corner part between the vertical frame 5 and the horizontal frame 14, and capable of reciprocating the chain-like body 44 in the length direction. By the chain-like body 44 moving in the length direction by the chain-like body driving part 45, opening/closing of the sliding screens 1, 1 and locking/unlocking of a lock are performed interlockingly.SELECTED DRAWING: Figure 1 【課題】 障子の開閉とロックの施解錠を連動して行うための機構を簡略化した窓開閉装置の提供。【解決手段】 枠１６に開閉自在に支持した障子１，１の開閉操作を行う障子開閉機構４２と、障子１，１を閉鎖状態でロックするロック部４３と、縦枠５と横枠１４に跨って配置され障子開閉機構４２とロック部４３とを連動可能に連結する鎖状体４４と、縦枠５と横枠１４とのコーナー部に配置され鎖状体４４を長さ方向に往復移動可能な鎖状体駆動部４５とを備え、鎖状体駆動部４５により鎖状体４４が長さ方向に移動することで、障子１，１の開閉とロックの施解錠が連動してなされる。【選択図】 図１
