To provide a double deck elevator capable of effectively suppressing the jumping-up of an upper car and a lower car while preventing the inclination of the upper car and the lower car as much as possible.SOLUTION: A jumping-up suppression mechanism includes a fixed pulley device 66 installed on a portion of an outer car 24 below a lower car 38 and a first wire rope 74 and a second wire rope 76 that are rope-like means guided by the fixed pulley device 66 and folded upward to connect an upper car 36 and the lower car 38. The upper car 36 and the lower car 38 are mutually pulled downward by the tensile force generated in the first wire rope 74 and the second wire rope 76. An action line of resultant force of the tensile force acting on the upper car 36 passes through the center of gravity of the upper car 36 in a plan view and an action line of resultant force of the tensile force acting on the lower car 38 passes through the center of gravity of the lower car 38 in a plan view.SELECTED DRAWING: Figure 3
【課題】上かごと下かごが傾くことを可能な限り防止しつつ、上かごと下かごの飛び上がりを効果的に抑制することが可能なダブルデッキエレベータを提供する。【解決手段】飛び上がり抑制機構を、下かご38よりも下方の外かご24部分に設置された固定滑車装置66と、固定滑車装置66に案内されて上方へ折り返され、上かご36と下かご38を連結する索状手段である第1ワイヤロープ74、第2ワイヤロープ76とを備え、第1ワイヤロープ74と第2ワイヤロープ76に生じる張力で上かご36と下かご38が相互に下方へ引っ張られる構成とされ、上かご36に作用する張力の合力の作用線が、平面視で、上かご36の重心を通り、下かご38に作用する張力の合力の作用線が、平面視で、下かご38の重心を通る構成とした。【選択図】図3
