- the bottom of the counterweight 8 on the way will be the vertical projection of the counterweight 8. It collides with the counterweight arm 30 in the plane, then the counterweight arm 30 follows the descent of the counterweight 8, and the counterweight arm 30 is the upper end safety switch 3 1 , The upper end safety switch 31 is actuated, and a braking force is applied to the hoisting machine 9.
- the car 7 does not stop with its braking force, the car 7 continues to rise, the counterweight 8 continues to descend, and the counterweight arm 30 that follows the lowering of the counterweight 8 is connected to the lower end safety switch 32.
- the lower end safety switch 32 is actuated, the power to the elevator is shut off, and the car 7 is emergency stopped. At this time, the lower end switch 32 is located just before the position where the movable portion 39 of the counterweight shock absorber 12 reaches its maximum stroke, that is, before the car 7 reaches the reaching uppermost position (not shown). Installed to operate.
- the upper terminal safety switch 14, the lower terminal safety switch 15 and the car arm 13 are provided in the vertical projection plane of the elevator car 7. Since the upper end safety switch 31, the lower end safety switch 32, and the counterweight arm 30 are provided in the vertical projection plane of the counterweight 8, which is a hoist, the crossing of the hoistway 1 is performed. The area can be reduced as compared with the conventional one.
- the upper terminal safety switch 14 and the lower terminal safety switch 15 are fixed to the car shock absorber 11, and the upper terminal safety switch 31 and the lower terminal safety switch 32 are Since the switch and the shock absorber are fixed to 1 and 2, respectively, the switch and the shock absorber are integrated, the installation work of the switch and the shock absorber is simple, and the installation cost is reduced.
- each arm 13, 30 moves up and down via a guide plate 19, 36 proposed by guides 18, 35, respectively.
- 30 up and down movement is reliable and stable.
- the guide, the guide plate and the spring are described as part of the shock absorber.
- the guide plate on which the switch and the arm are fixed slides up and down on the lower surface of the elevating body.
- a fixed guide may be used. In this case, the elevating body descends, and the distal end surface of the arm comes into contact with the arm receiver provided on the bottom surface of the pit, and the base end surface of the arm approaches and contacts the switch. The switch operates.
- FIG. 4 is a configuration diagram of an elevator apparatus according to Embodiment 2 of the present invention.
- the car arm 13 is directly fixed to the car 7, and the car arm 13 directly follows the vertical movement of the car 7.
- the counterweight arm 30 is directly fixed to the counterweight 8, and the counterweight arm 30 directly follows the vertical movement of the counterweight 8. At this time, since the car 7 and the counterweight 8 move up and down while being supported horizontally on guide rails installed vertically in the hoistway (not shown), the arm 13 fixed to the car 7 and the counterweight 8 is used. , 30 vertical movement is reliable and stable.
- the springs 22, 37 for returning the arms 13, 30, and the springs 22, 3, 7 are guided, as compared with those of the embodiment 1.

- the springs 22 and 37 are arranged as in the first embodiment, only the compressed springs 22 and 37 are arranged at the lowest position to reach the car (or the lowest position to reach the counterweight). Height is required. Since the stroke and height of the shock absorbers 11 and 12 become smaller when the rated speed of the elevator device is small, the height at which the compressed spring can be arranged becomes shorter. On the other hand, since the distance between the upper end safety switches 14 and 31 and the lower end safety switches 15 and 32 is constant regardless of the rated speed of the elevator, the stroke required for the spring is Even if the rated speed of the equipment is low, it does not change much. Therefore, it becomes more difficult to arrange the spring as the rated speed of the elevator apparatus becomes smaller.
- the arm is fixed to the elevating body and the shock absorber is fixed to the pit.
- the shock absorber may be directly fixed to the elevating body and the arm may be fixed to the pit.
