To safely protect, in a car upper safety fence of an elevator, a maintenance worker even if the maintenance worker is sandwiched between the safety fence and a balancing weight.SOLUTION: A car upper safety fence 50 of an elevator is a safety fence provided on a car and surrounding a work area for a maintenance work on the car. The car upper safety fence 50 comprises: a plurality of fence base parts 52, 54, 56, 58 provided upward on the car; and a car upper handrail part 60 connecting respective top parts of the plurality of fence base parts 52, 54, 56, 58. A predetermined safe external force value is set in advance as a range in which a maintenance worker 6 is safely protected in the event that the maintenance worker 6 is sandwiched between a balancing weight 22 of the elevator and the car upper handrail part 60 and receives external force. If the car upper handrail part 60 receives external force exceeding the predetermined safe external force value, part of a portion connecting adjacent fence base parts falls or breaks and separates.SELECTED DRAWING: Figure 3
【課題】エレベーターのかご上安全柵において、仮に、安全柵と釣合おもりの間に保守作業員が挟まれても、保守作業員を安全に保護することである。【解決手段】エレベーターのかご上安全柵50は、乗りかごのかご上に設けられ、かご上での保守作業のための作業領域を囲む安全柵である。かご上安全柵50は、かご上に立設された複数の柵基部52,54,56,58と、複数の柵基部52,54,56,58の頂部を結ぶかご上手摺部60とを備える。そして、エレベーターの釣合おもり22とかご上手摺部60との間に保守作業員6が挟まれて外力を受ける場合に保守作業員6が安全に保護される範囲として所定の安全外力値があらかじめ定められている。かご上手摺部60は、所定の安全外力値を超える外力を受けた場合に、隣接する柵基部を結ぶ部分の一部が脱落または破損して分離する。【選択図】図3
