PROBLEM TO BE SOLVED: To alert to a risk that an object is caught between a car of an elevator and a car door and is broken with an opening operation of the car door.SOLUTION: An alarm device 1 mounted inside of a jamb 3 within a car comprises: a switch board 5 supported by coil springs 6 and a buzzer 8 having an abutting part 8a arranged with a predetermined interval from the switch board 5. The car door 9 starts an opening operation when the car stops at a stop floor. A bag of a passenger 12 having a contact with the car door 9 is caught into a gap between the car door 9 and the alarm device 1 interlocking the opening operation of the car door 9 and is pulled further. A switch board 5 is moved by this pulling force in a direction toward the abutting part 8a of the buzzer 8 against an energization of the coil spring 6 and when it contacts with the abutting part 8a, the buzzer 8 raises an alarm.SELECTED DRAWING: Figure 4
【課題】かごドアの開動作に伴い物体がエレベーターのかごとかごドアとの間に挟まれ破損することに対する注意喚起を行う。【解決手段】かご内の三方枠3の内側に取り付けられる警報装置1は、コイルばね6で支持されるスイッチ板5と、スイッチ板5から所定量の間隔を設けられた当接部8aを有するブザー8と、を備える。かごドア9は、かごが停止階で停止すると開動作を開始する。かごドア9と接触していた乗客の鞄12は、かごドア9の開動作に連動してかごドア9と警報装置1との間の隙間に挟まれ更に引き込まれる。スイッチ板5が、この引き込まれる力によってコイルばね6の付勢力に反してブザー8の当接部8aに近づく方向へ移動し、そして当接部8aに接触すると、ブザー8は警報を発する。【選択図】図4
