Description

  The present invention relates to an elevator escape device that allows passengers to escape by themselves when passengers are confined in an elevator cab due to an earthquake or the like.

  Conventionally, when a passenger is trapped in an elevator car due to an earthquake or the like, there is currently no choice but to wait for rescue from the outside. Also, it was impossible to escape by yourself.

  Also, as a conventional technique, when a car stopped between floors is in equilibrium with a counterweight, a rescue weight is attached to the governor rope to make it unbalanced in order to rescue passengers trapped in the car. An elevator passenger rescue device is known in which a brake is manually released using a brake release tool to raise and lower a car to the nearest floor and rescue a passenger trapped in the car (see, for example, Patent Document 1). .
