Definitions

  • the present invention relates to an elevator system in which machines/equipment(s) such as a hoisting machine, a control console, a governor and others are disposed internally of an elevator shaft, i.e., an elevator system which is not equipped with a so-called machine room.
  • this invention is concerned with the elevator system which is so improved that an elevator cage or car can be moved more easily and accurately when the car is moved to the nearest floor while observing a mark affixed to a governor rope in a save operation upon occurrence of emergency event or the like.
  • An elevator cage position detection system known from EP-A-0712804 .
  • marks are affixed to the governor rope or a main rope in advance while an inspection panel is disposed at an elevator hall, wherein in the emergency operation, such method is adopted that the car is moved while visually observing the mark(s) affixed to the governor rope or the main rope through an inspection window provided in a panel for inspection.
  • a light or lamp is generally installed for illustrating the governor rope or the main rope so that the mark can visually be seen even in the event that the power supply service is interrupted.
  • the conventional elevator shaft such as briefed above has suffered a problem that the mark may be erroneously recognized or identified when it is visually observed. Besides, the mark is rather difficult to visually observe, giving rise to another problem. More specifically, there run a large number of ropes within the elevator shaft. Consequently, there arises a problem that irrelevant rope may be mistaken as the governor and/or main rope or the mark is difficult to be discerned because the inspection window and the light are not installed at the respective proper positions in many systems.
  • This invention has been made with a view to solving the problem mentioned above, and it is an object of this invention to provide an elevator system which makes it possible to visually observe the governor rope intrinsically subjected to the observation and movable synchronously with the movement of the elevator car to thereby allow the car to move highly easily and accurately when the car is to be moved while observing the mark affixed to the governor rope through the inspection window in emergency save operation or the like event.
  • An elevator system includes an elevator car moving reciprocatively upward and downward within an elevator shaft, a governor installed at a top portion of the elevator shaft, a tension sheave disposed at a bottom portion of the elevator shaft, a governor rope spanned in a loop-like form between the governor and the tension sheave so as to be moved circulatorily between the governor and the tension sheave, the governor rope being composed of a car-connected governor rope section suspended from the governor into the elevator shaft and connected to the elevator car and a counterpart governor rope section extending substantially in parallel and adjacent to the car-connected governor rope section, the governor rope being affixed with marks at predetermined positions associated with the elevator car, an illumination means disposed substantially between the car-connected governor rope section and the counterpart governor rope section for illuminating at least the car-connected governor rope section, and an inspection window provided at a location at which a portion of the car-connected governor rope section illuminated by the illumination means can be visually observed, wherein the car-connected governor rope section, the counterpart governor rope section and the illumination means
  • the illumination means may be disposed between the car-connected governor rope section and the counterpart governor rope section.
  • the illumination means may be f ixedly secured to a governor mounting platform.
  • the illumination means may be disposed at a position which is of an approximately same height as the inspection window.
  • the illumination means may be mounted on an illumination means mounting arm secured to a guide rail and projecting therefrom.
  • electric power for the illumination means may be supplied from an emergency power supply source.
  • a switch of the illumination means may be installed in the vicinity of the inspection window.
  • the illumination means may be interlocked with a cover of the inspection window such that the illumination means is lit when the cover is opened.
  • Figure 1 is a cross sectional view showing an elevator shaft of an elevator system according to a first embodiment of this invention, i.e., a first mode for carrying out the invention.
  • Figure 2 is a vertical sectional view of the elevator shaft showing an arrangement in which a governor and a lamp or light are installed.
  • Figure 3 is a view showing schematically an inspection panel installed at an elevator hall. This panel will hereinafter be termed the hall inspection panel for the convenience of description.
