In this position, the upper guide 38 of the upper guide device 35 of the car 4 is positioned so as to be movable along the upper rail 15 extending in the vertical direction by the rotation support member 37, and the lower guide 40 of the lower guide device 36 is The position is movable along the lower rail 16 extending in the vertical direction by the rotation support member 39. When the hoisting machine 22 is driven at this position and the main rope 24 is driven, the length of the main rope 24 between the first and second main rope fulcrums 31 and 33 is gradually shortened, and the car 4 has the guide rail device 14. The first hoistway 11 is lifted along (see FIG. 1) and moved from the position A in FIG. 10 to the position B in FIG. 11 and the position C in FIG. At this time, the counterweight 26 descends in the first hoistway 11 along a counterweight guide rail (not shown).

  When the operation of the driving device 19 is continued, the car 4 reaches the position D in FIG. 13 and reaches the entrance portion of the communication path 13 at the upper end of the first hoistway 11. At this time, the suspension device 41 is in the position indicated by the broken line, and the height positions of the first and second push-down wheels 32 and 34 are the same, but the suspension portion of the main rope 24 between the main rope fulcrums 31 and 33 Is tilted upward in the figure. For this reason, the car 4 does not move. In this state, while winding the main rope 24 with the hoisting machine 22, the first push-down wheel 32 is raised and the second push-down wheel 34 is lowered to the position indicated by the solid line. When the descent continues, the position shown in FIG. 14 is obtained.

Become. In this state, when the hoisting machine 22 is reversed and the first push-down wheel 32 is lowered while slightly extending the main rope 24, the suspended portion of the main rope 24 is inclined to the right. The suspension wheel 25 supported by the suspension moves to the right in the drawing along the inclination of the main rope 24 by gravity and becomes the F position of the car 4 shown in FIG. 15, and the car guide rail 14 (see FIG. 1). The car guide rail 14 is supported by the car guide rail 14 having a downward slope in the drawing beyond the highest vertex.

  Therefore, if the second push-down wheel 34 is lowered while continuing the reverse rotation of the hoisting machine 22 and feeding the main rope 24 from this position, the car 4 further descends and moves to the G position shown in actual battle in FIG. Further, if the hoisting machine 22 continues to reverse, the main rope 24 is drawn out, and the car 4 is guided along the car guide rail 14 and passes through the H position in FIG. 17 and the I position in FIG. The position on the second landing 2 shown by the solid line in FIG. 19 is reached. During this time, the counterweight 26 gradually rises to the uppermost position in FIG.

  When driving the car 4 from the second hoistway 12 to the first hoistway 11, the driving operation described so far may be performed in reverse.

  Thus, according to the elevator apparatus of the present invention, the car 4 can be moved up to the second landing after being lifted once from the first landing without changing passengers, and a complicated mechanism is required. It has a simple structure and is easy to install and maintain, and passengers do not need to transfer on the way.
