摘要： An elevator car upper handrail apparatus, in which a connecting body is provided between respective ends of first and second side handrails on a landing side. The connecting body includes an opening/closing member which is rotatable between a closed position, in which a path for movement of a worker from a landing to a car upper surface is closed by the opening/closing member, and an open position, in which the path for movement is opened by the opening/closing member. The opening/closing member is configured to return automatically to the closed position. When the opening/closing member is in the closed position, the connecting body transmits an external force applied to one of the first and second side handrails in the width direction of a car to the other of the first and second side handrails.

摘要： A mechanism that allows a ladder to be moved to either a use position or a retracted position. The ladder can be moved from the retracted position to the use position with a minimal effort, and the ladder moves by itself from the use position to the retracted position. A pit ladder apparatus for an elevator according to the present invention includes a position change means to be provided in a fixing metal frame fixed to the hoistway and allowing a ladder to be moved to either the use position when the ladder is used or the retracted position for retracting the ladder when it is not used so as not to interfere with operation of the elevator.
