Definitions

  • the present invention relates to a laterally suspending structure for an elevator car, and particularly to a laterally suspending structure of an elevator car of a type having its entire width smaller than that of a balance weight.
  • a structure for suspending an elevator car is of a roof suspending type as shown in Fig. 2, in order to stabilize the attitude of the elevator car during movement.
  • One object of the present invention is to provide an elevator having a moving stroke which is greater than that of a roof suspending type elevator car, within a fixed moving space.
  • an elevator in an elevator according the present invention, there is provided a laterally suspending structure for an elevator car composed of support members secured to both side surfaces of the elevator car and rope fastening members supported and secured to the upper end faces of the support members, the rope fastening members for suspending the car being set at a level slightly lower than that that of the roof surface of the car.
  • the fastening rope fastening ends are set at a level slightly lower than that of the upper surface of the roof of the car. Further, due to that the rope fastening members secured to the support members are arranged at equal distances with respect to the vertical line passing through the gravitational center of the car, suitable blancing is taken for suspending the car.
  • Fig. 1 is a schematic perspective view illustrating a laterally suspending structure for a car according to the present invention
  • Fig. 2 is a schematic perspective view illustrating a conventional roof suspending type structure for a car.
  • an elevator car 1 is fastened to first ends of ropes 3 by rope fastening members 2.
  • These rope fastening members 2 are tightly fixed to support members 20 arranged on both side surfaces of the upper section of the car at a level slightly lower than the upper surface of the roof of the car.
  • first sheaves 4 and the second sheaves 5 are supported to sheave support beams 9 in an elevator machine room by means of of sheave shafts 8.
  • the car has car guide rollers 11 attached to both sides thereof and engaged with car guide rails 10.
  • a balance weight has balance weight guide rollers 13 engaged with balance weight guide rails 12.
  • the balance weight 6 is arranged so as to carry out linear motion in the vertical direction along a column 18 which is supported at both ends thereof to an upper end support part 15 fixed a ceiling beam 14 and a lower end support part 17 fixed to a floor frame 16, the column 18 being the secondary conductor of a linear induction motor.
  • Reference numeral 19 denotes the primary conductor of the induction motor carrying out linear motion. In the case of the linear induction motor shown in this embodiment, it is of a type such that the secondary conductor is held at the position of installation while the primary conductor alone carries out linear motion.
  • the present invention is optimum particularly for an elevator of such a type that the entire width of a car is smaller than that of the balance weight.
  • the present invention has been explained in the above-mentioned embodiment using a cylindrical linear motor driven elevator, the laterally suspending structure for a car, according to the present invention should not be limited to the cylindrical shape linear motor driven elevator, and the present invention can be applied for every type of elevators.
  • the present invention can be practices in various forms without departing the sprit and main principal of the present invention.
  • the present invention is arranged as mentioned above, and therefore offers the following advantages.
  • the rope fastening ends for the car are set at a level slightly lower than that of the upper surface of the roof of the car, the moving stroke of the car within a predetermined moving space can be made to be maximum. Further, the rope fastening members are arranged at equal distances with respect to the vertical line passing through the gravitational center of the car, and accordingly, optimum balancing is taken for suspending the car.
  • Fig. 1 is a schematic perspective view illustrating an elevator having a laterally suspending structure according to the present invention
  • Fig. 2 is a schematic perspective view illustrating a conventional car roof suspending type elevator.
