To provide a double deck elevator that can prevent jump-up of an upper car and a lower car, only when it is necessary as actually as possible.SOLUTION: An inter-floor adjustment hoist 40 is held so as to be displaceable upward from a fixed position with respect to an outer car 24. A compression coil spring 70 is provided, which has resilience for displacing the hoist 40 upward from the fixed position while the weights of an upper car and a lower car are not applied to the hoist 40 via a wire rope 54. When a limit switch 74 detects that the hoist 40 has displaced relatively upward from the fixed position with respect to the outer car 24, an upper car brake device and a lower car brake device are switched from a releasing state to a gripping state, the upper car brake device and the lower car brake device being switchable between the gripping state in which vertical relative displacement of the upper car and lower car with respect to the outer car 24 is braked by gripping a rail vertically provided on the outer car 24 and the releasing state in which gripping is released.SELECTED DRAWING: Figure 3
【課題】可能な限り現実に必要なときのみに、上かごと下かごの飛び上がりを抑制し得るダブルデッキエレベータを提供する。【解決手段】階間調整用巻上機40を外かご24に対し定位置から上方へ変位可能に保持し、ワイヤロープ54介して巻上機40に上かごと下かごの重量が掛からない状態では、巻上機40を定位置から上方へ変位させる復元力を有する圧縮コイルバネ70を設け、巻上機40が外かご24に対し、定位置から上方へ相対変位したことをリミットスイッチ74で検出すると、外かご24に上下方向に設けられたレールを把持することにより上かごと下かごの各々の外かご24に対する上下方向への相対変位を制動する把持状態と把持が開放された開放状態とに切り換え可能な上かご制動装置と下かご制動装置を解放状態から把持状態に切り替える構成とした。【選択図】図3
