[0017]
In the seismic isolation building elevator apparatus configured as described above, when the hoisting device 9 is energized, the car 11 and the counterweight 12 are lifted and lowered in opposite directions via the main rope 10. When the car 11 and the counterweight 12 descend in a state exceeding the predetermined speed, the shock is buffered by the shock absorber 13. When the non-base-isolated building 1 is vibrated by an earthquake, the base-isolated building 5 including the upper hoistway 15 is displaced in the horizontal direction with respect to the non-base-isolated building 1 by the base-isolating means 4.

[0022]
Embodiment 2. FIG.
FIG. 6 is a view showing an example of another embodiment of the present invention. FIG. 6 is a transverse plan view of a hoistway corresponding to the above-described FIG. The seismic isolation building elevator apparatus is configured in the same manner as in the embodiment. In the figure, the same reference numerals as those in FIGS. 1 to 5 denote corresponding parts, 28 is an operating device that expands and contracts, and one side is attached to the inner surface of the upper hoistway 15 and the other side is attached to the frame body 24.

[0025]
In the embodiment of FIG. 6, the expansion / contraction operation of the actuating device 28 is prevented by the operation of the control device 30 at the normal time without an earthquake. Thereby, the guide rail 26 is fixedly supported by the upper hoistway 15 through the frame 18 and the frame 24. For this reason, the second type support means 31 does not resonate due to vibration or the like associated with the raising or lowering of the car 11 or the like. Problems such as occurrence can be prevented in advance.

Further, in the event of an earthquake, the control device 30 is operated by the output of the detection device 29 due to the shaking thereof, and the expansion and contraction prevention of the actuation device 28 is released, so that the guide rail 26 is elastically supported, and the guide rail 26 is shaken. Displacement is absorbed. As a result, the guide rail 26 of the upper hoistway 15 can always be held at the normal position, and the elevator can be operated normally without being affected by the shaking of the earthquake.
