  • Damper for elevator, and elevator
    Patent number: 11414300
    Abstract: A damper for elevator, and an elevator, that enable reduction of the maximum deceleration of a lifting/lowering body by suppressing deformation of a foamed body for absorbing impact. The damper for elevator includes: urethane foam having a collision surface with which a lifting/lowering body is to collide; and an outer peripheral member attached to the outer side of the side-part surface of the urethane foam and having an inner side surface bowed outward, wherein impact by collision of the lifting/lowering body is buffered by deformations of the urethane foam and the outer peripheral member.
    Type: Grant
