Definitions

  • the present invention relates to an elevator car and particularly relates to a mounting construction for a beam on which a hanger rail that guides opening and closing of a car door is disposed.
  • a beam is mounted onto a car frame that supports a cage by means of a mounting arm.
  • a hanger rail that guides opening and closing of a car door is disposed on the beam.
  • a reinforcing rod is linked obliquely between the mounting arm and the car frame (see Patent Literature 1, for example).
  • reinforcing materials are disposed on an outer surface of a cage without using a car frame.
  • a pair of side wall reinforcing materials are disposed on outer surfaces of a pair of side walls of the cage, and a ceiling reinforcing material is disposed on an outer surface of a ceiling of the cage.
  • a pair of brackets are fastened between the side wall reinforcing materials and the ceiling reinforcing materials.
  • a beam of a car door apparatus is fastened to the brackets, a doorway frame, and the ceiling (see Patent Literature 2, for example).
  • Patent Literature 3 shows elevator systems and, more specifically, door operators for imparting rectilinear motion to the door panels of an elevator car. Patent Literature 3 discloses the preamble of claim 1.
  • Patent Literature 4 shows elevator door operating mechanisms and means for opening and closing the door of an elevator, both by hand control and in automatic electrically controlled elevators.
  • Patent Literature 5 shows a carrier for door drives of lifts.
  • Patent Literature 1 Because members such as rods, a mounting arm, etc., are required in order to mount the beam onto the car frame, the number of parts is increased. Because the beam is mounted onto the car frame, installation and adjustment such as centering to align the center of the car doorway that is disposed on the cage and the center of the beam are time-consuming.
  • Patent Literature 2 Because the conventional car construction that is disclosed in Patent Literature 2 has a simple construction that does not use a car frame, on the other hand, it can be applied only to small elevators. Because the construction does not support the cage on a car frame by means of rubber vibration isolators, riding comfort is impaired. In addition, using this construction, installation and adjustment such as centering to align the center of the car doorway and the center of the beam is also time-consuming.
  • the present invention aims to solve the above problems and an object of the present invention is to provide an elevator car that can facilitate installation and adjustment of a beam by a simple configuration while avoiding deterioration in riding comfort.
