<p>In conventional elevators, the weight of a cage room is supported by a cage frame surrounding the cage room and acts upon the cage frame through a vibration damping member provided under the floor of the cage room, thus causing the weight of the cage room to act in a concentrated manner upon the position at which the vibration damping member is provided. In this context, the position at which the vibration damping member is provided needs to be enhanced in rigidity. This raises the problems; an increase in the weight of the cage frame and an increase in costs due to an increase in reinforcement parts count. In view of these problems, an elevator cage frame structure is provided which includes a vertical vibration damping mechanism between the top of a vertical pillar and the ceiling of the cage room and a link mechanism that allows the vertical pillar of the cage frame to follow the cage room when displaced in the horizontal direction.</p> |
