ELEVATOR DEVICE

摘要

An elevator system includes a machine room 200 disposed in a space which overlaps neither a space in which an elevator car 5 moves upward and downward within an elevator shaft 1 of the elevator system nor a virtual space defined in the case where the elevator car 5 has moved along an extended path in the up/down direction. The machine room 200 is comprised of a machine room floor 201 provided, protruding substantially horizontally from a wall surface of the elevator shaft 1, a shifting means 204 for allowing a maintenance person to get on the machine room floor from the elevator car or a building, and an extension floor 208 provided projectably from the machine room floor 201 in a substantially horizontal direction. The extension floor 208 is provided so as to move reciprocatively between a housed position at which the extension floor 208 is so housed as not to protrude into the space in which the elevator car 5 has moved in the up/down direction and the virtual space defined in the case where the elevator car 5 has moved along the path extended in the up/down direction and a protruding position at which the extension floor 208 is protruded from the machine room floor 201 so as to extend the machine room floor 201, and wherein heightwise distance from the machine room floor 201 and the extension floor 208 to a ceiling of the elevator shaft 1 is selected so as to allow the maintenance person to work.
