  • An elevator car position checking apparatus according to Embodiment 1 includes the inspection window 17a and the wire apparatus 38.
  • an elevator car position checking apparatus of this kind because a wire 36 specifically for checking elevator car position is disposed separately from the main rope 7 inside the hoistway 1 along the raising and lowering direction of the elevator car 4, the position of the inspection window 17a can be set independently from the layout of the counterweight 5 and the driving machine 6, enabling the degree of freedom in the installation position of the inspection window 17a to be increased. Furthermore, since it is sufficient that a wire apparatus 38 having a simple construction be disposed, increases in cost can also be suppressed.
  • the inspection window 17a is disposed inside the landing inspection panel 16, the degree of freedom in the installation position of the landing inspection panel 16 can also be increased, enabling the design of the landing 14 to be improved. Furthermore, since the lower portion arm 34 supporting the lower portion pulley 33 is pivotable around the pin 35, tension can be applied to the wire 36 by a simple construction.
  • Figure 4 is a plan showing part of elevators according to Embodiment 2 of the present invention.
  • two elevators are installed in parallel.
  • the layout of major equipment such as the elevator car 4, the counterweight 5, the driving machine 6, the control board 11, etc., is the same in both the left and right elevators.
  • the landing inspection panels 16 are disposed outside the two sets of landing doors 15.
  • Embodiment 2 by using a wire apparatus 38 similar to that of Embodiment 1 in the elevator on the right in the figure, it is possible to simply make the arrangement of the landing inspection panels 16 symmetrical while keeping the layout of major equipment the same on the left and right. Consequently, the degree of freedom in the installation positions of the inspection windows 17a and the landing inspection panels 16 can be increased while suppressing increases in cost.
  • FIG. 5 is a plan showing observation elevators according to Embodiment 3 of the present invention.
  • the hoistway walls 1b behind the elevator cars 4 are each composed of transparent glass.
  • Rear portions of the elevator cars 4 (portions facing the hoistway walls 1b) are also composed of transparent glass for observation.
  • the two counterweights 5 are disposed between the two elevator cars 4 such that passengers inside the elevator cars 4 can easily see outside.
  • the landing inspection panels 16 are disposed outside the two sets of landing doors 15.
  • the two landing inspection panels 16 were disposed between the two sets of landing doors 15, as shown in Figure 14.
  • the wire apparatus 38 by disposing the wire apparatus 38 on an opposite side of the elevator car 4 from the counterweight 5 in both the left and right elevators, it is possible to position the inspection windows 17a outside the two sets of landing doors 15. Consequently, the degree of freedom in the installation positions of the inspection windows 17a and the landing inspection panels 16 can be increased.
