PROBLEM TO BE SOLVED: To solve a problem such that, when a maintenance person uses an unlocking key 40 and unlocks a landing door 50 by manual operation at an elevator landing, during maintenance time or the like, a keyhole 51 of the landing door 50 is disposed above the landing door 50, so that a maintenance person who has a small height cannot perform an unlocking operation easily, therefore, it is considered to install an extension tool to the unlocking key 40, but it cannot be easily used and has margin of improvement.SOLUTION: An extension tool 1 for supporting an unlocking key 40 is stretchable, and a hinge-state support part 20 is attached to the extension tool 1. A holding part 32 and a wing bolt 33 hold the unlocking key 40 to an attachment part 30, and the attachment part 30 is fixed to the support part 20, thereby oscillation of the unlocking key 40 to the support part 20 is prevented, and an unlocking operation by the unlocking key 40 is facilitated.SELECTED DRAWING: Figure 1

    【課題】 メンテナンス時などに保守員がエレベータ乗場から解錠キー40を使って乗場ドア50を手動で解錠する際、乗場ドア50の鍵穴51は、乗場ドア50の上方に設けられているため、小柄な作業員にとっては解錠操作が困難である。そのため、解錠キー40に延長器具を設けることが考えられているが、使いにくさがあり、改良の余地があった。【解決手段】 解錠キー40を支持する延長器具1を伸縮自在にするとともに、この延長器具1にヒンジ状の支持部20を取り付け、保持部32と蝶ボルト33によって解錠キー40を取付部30に保持し、支持部20に取付部30を固定することにより、支持部20に対する解錠キー40の揺動を防止して、解錠キー40による解錠操作を行いやすくした。【選択図】 図1
