PROBLEM TO BE SOLVED: To make it possible to generate a warning sound without providing an electric circuit on an elevator if a landing door has been opened when an elevator car is not staying on the floor of the landing door.SOLUTION: A safety device of an elevator entrance generates a warning sound if a landing door 1 has been opened when an elevator car is not staying on the floor of the landing door. The safety device includes: a movable body composed of a hitting part 2 which can be flexibly deformed and moves with the opening movement of the landing door 1; and an interfering part including an engaging part 8 and a part 9 to be hit which generate a warning sound by interfering with the hitting part 2. The hitting part 2, the engaging part 8 and the part 9 to be hit are disposed so that the hitting part 2 can interfere with the engaging part 8 and part 9 to be hit if the landing door has been opened when an elevator car is not staying on the floor of the landing door. In addition, the safety device has an interfering part moving mechanism which moves the engagement part 8 and part 9 to be hit with the opening movement of the landing door 1 to prevent the hitting part 2 from hitting the part 9 to be hit.SELECTED DRAWING: Figure 2

    【課題】電気回路を設けることなく、階床に乗かごが存在していないときに乗場戸が開かれた際に、警報音を発生するようにする。【解決手段】本発明は、階床に乗かごが存在しないときに乗場戸1が開かれた際に、警報音を発生させるエレベータの出入口部の安全装置において、乗場戸1の開動作に伴って移動する撓み変形可能な叩打部2から成る移動体と、この叩打部2との干渉によって警報音を発生させる係合部8及び被叩打部9を含む干渉部とを備えている。叩打部2と、係合部8及び被叩打部9とは、階床に乗かごが存在しないときに、叩打部2と、係合部8及び被叩打部9とが干渉可能となるように配置してある。また本発明は、乗場戸1の開動作に伴って係合部8及び被叩打部9を移動させ、叩打部2による被叩打部9の叩打を阻止する干渉部移動機構を備えている。【選択図】図2
