To provide an elevator door support device in which a working space is not narrowed.SOLUTION: An elevator door support device comprises a pair of foldable vertical columns of a car upper handrail fixed to the side of a door device at a car frame upper part, a pair of braces which support an outer end part of a car frame upper part and can support load acting on a width direction of the door device, a first support part which rotatably supports one end of the brace at the outer end part, a second support part which rotatably supports the other end of the brace at the top part of the vertical column, and a holding part which detachably holds the top part of the vertical column and the car frame upper part, when the vertical column is folded, the vertical column is arranged on the opposite side of the door device when viewed in the vertical direction and is held at the car frame upper part via the holding part, and the first support part and the second support part are arranged at approximately the same height, and when the vertical column is erected, the brace is erected together with the vertical column via the second support part and is disposed approximately parallel to the width direction of the door device when viewed from the vertical direction.SELECTED DRAWING: Figure 1
【課題】作業スペースが狭くならないエレベータのドア支持装置を実現する。【解決手段】エレベータのドア支持装置は、かご枠の上部のドア装置側に固定されるかご上手摺の折り畳み可能な一対の縦柱と、かご枠上部の外端部に支持し、ドア装置の間口方向に作用する荷重を支持可能な一対の筋交いと、筋交いの一端を外端部に回動可能に支持する第一の支持部と、筋交いの他端を縦柱の上部に回動可能に支持する第二の支持部と、縦柱が折り畳まれたとき、縦柱の上部とかご枠上部とを着脱可能に保持する保持部と、を備え、縦柱が折り畳まれたとき、縦柱は、鉛直方向から見てドア装置と反対側に倒伏して配置されると共に保持部を介してかご枠上部に保持されて、第一の支持部と第二の支持部とは略同じ高さに配置されており、縦柱が立設されたとき、筋交いは、第二の支持部を介して縦柱と共に立設されて、鉛直方向から見てドア装置の間口方向に対して略平行に配置される。【選択図】図1
