PROBLEM TO BE SOLVED: To provide a tension application device of an elevator landing door interlocking rope, that is capable of preventing an interlocking rope from being slackened while reducing the elongation of the interlocking rope by applying fixed tension to the interlocking rope.SOLUTION: A tension application device 40 is provided with, on a landing door 23 in which a right door 24 is provided so as to be opened/closed along with the cage door 15 of a cage 12, and this opening/closing motion is linked with a left door 26 by an interlocking rope 35: a pair of pulleys 42a and 42b that come into contact with the interlocking rope 35; a tension application mechanism 45 that press the pulleys 42a and 42b to the interlocking rope 35 to apply tension to the interlocking rope 35; a detection unit 37 that detects pressing forces applied on the interlocking rope 35 by the pulleys 42a and 42b; and a control unit 20 that controls the tension application mechanism 45 so that the pressing forces can become equal to preset values.SELECTED DRAWING: Figure 2
【課題】連動ロープに一定の張力を付与することで連動ロープの伸びを軽減しつつ連動ロープの弛みを防止できるエレベータ乗場扉用連動ロープの張力付与装置を提供する。【解決手段】張力付与装置40は、右扉24が乗りかご12のかご扉15に従動して開閉するように設けられ、この開閉動作を連動ロープ35により左扉26に連動させる乗場扉23において、連動ロープ35に接触するプーリ対42a,42bと、プーリ対42a,42bを連動ロープ35に押し当てて連動ロープ35に張力を付与する張力付与機構45と、プーリ対42a,42bが連動ロープ35に作用させる押圧力を検出する検出部37と、押圧力が予め設定した値となるように張力付与機構45を制御する制御部20とを備えている。【選択図】図2
