Embodiments of the present invention will be described below with reference to the drawings.
1 to 3 and FIGS. 8 and 9 are diagrams showing an embodiment of the present invention. First, the overall configuration of the elevator will be described with reference to FIG. As shown in FIG. 8, a hoisting machine (not shown) is installed in the upper machine room 2 of the elevator hoistway 1, and the main rope 4 is suspended from the main sheave 3 of the hoisting machine. Yes. A car 5 is suspended from one end of the main rope 4. On the other hand, a counterweight 6 is suspended from the other end of the main rope 4.

  A compen- sation rope 8 is attached to the lower side of the car 5 and the counterweight 6 in order to cancel the change in the mass of the main rope 4 due to the position of the car 5. Compensation 7 is provided. Further, a cable 9 for power supply and control signal transmission / reception is suspended from the lower end of the car 5. When the building beam 10 is on the wall surface side of the hoistway 1 of the cable 9, a wire net 11 is provided between the cable 9 and the building beam 10 to protect the cable 9 that moves as the car moves up and down. Yes.

  Moreover, as shown in FIG. 9, long objects, such as the ropes 4 and 8 and the cable 9, are shaken by the shaking of a building due to an earthquake or a wind. In order to prevent the ropes 4 and 8 and the cable 9 from being caught by the device protrusions in the hoistway 1, a protective wire 20 is installed in the hoistway 1 in accordance with the elevator seismic design / construction guidelines. Here, FIG. 9 is a view of the elevator hoistway 1 as viewed from a direction different from that of FIG. 8 by 90 °.

  As shown in FIG. 9, a lowermost landing 21 a and intermediate landings 21 b and 21 c are installed toward the hoistway 1.

  The lower end of the protective wire 20 installed in the hoistway 1 is locked to a locking plate 25 provided in the pit 22 via a hook 26. The protective wire 20 extends upward from the locking plate 25 and is supported and fixed by a fixture 30 installed at each landing 21a, 21b, 21c.

  The protective wire 20 and the fixture 30 constitute an elevator protective wire mounting structure.
