す虞れがあった。However, when the drive motor (7) is started and the car (+) is started, various disturbances occur during its running, causing the car (1
) may be excited, which may make the passengers in the car (1) feel uneasy. For example, when the drive state of the motor (7) shifts from power to regeneration or from regeneration to power, when the gears of the reduction gear (8) change gears due to backlash, an impact force is generated. This is transmitted to the car (1) via the rope (3), resulting in an uncomfortable ride in the elevator. This impact force is
Cart (1) bottom elastic member (12) and upper beam (2A)
By making the cushioning effect of the lower shock absorbing spring member (14) sufficiently effective, the riding comfort can be alleviated and the riding comfort can be improved. However, in this case, as passengers get on and off, the shock absorbing spring member (14) etc. will be sensitive to this and will very easily cause longitudinal vibration, which will give the passengers a new sense of anxiety. This is undesirable, and the car (1) is aligned with the floor (13) by the landing device (lO) and stands at 11-1, and then the brake (9) is applied to maintain the stopped position. However, at this time, the cushioning action of the buffer spring member (14) acts sharply, so the car (1) is moved to the specified floor (
13) could not be within the predetermined range (approximately ±10 m+++), and there was a risk that the floor alignment would occur frequently, resulting in an unfavorable result.

提案するものである。The present invention has been made in view of the above points, in which a second spring member is provided in addition to the buffer spring member, and when the elevator is running, the second spring member is activated to absorb disturbances during the run. The present invention proposes an elevator that does not align the floors when it stops.

13), the position detector output relay is activated, its normally open contact (19) is closed, and the second spring member (16) is closed by the dynamic magnetism of the solenoid (18A).
) does not function, and only the shock absorbing spring member (14) functions, so the car (1) hardly vibrates and passengers can get on and off without feeling any anxiety. Then,
Start the elevator and issue the speed command V as shown in Figure 5(a).
When p is issued, the car (1) is gradually accelerated, and after t1 seconds it reaches the position is demagnetized. The iron core (18B) is the second
The biasing force of the spring member (16) returns to the original free state, and the buffer spring member (14) is in series with the spring constant, which greatly reduces the spring constant.
8), the car (1) starts extremely smoothly and provides a comfortable ride. After running at a constant speed based on the post-start speed command Vp, when approaching another predetermined floor (not shown), the car (1) starts while being decelerated by the deceleration speed command Vp as shown in FIG. Xl on another predetermined floor after t2 seconds from time
When approaching to mm, the speed command Vp is set to the landing device (10
), and at this time, when the position detector detects the output power Vxl of this landing device (10), the detection relay picks it up and the normally open contact (18) closes.
The solenoid (18A) is energized to stop the function of the second spring member (16). This allows the car (1) to
can ensure a stable state without vibration.

ことは言うまでもない。Note that the switching of the signal between the landing device (10) and the speed command Vp is performed when the car (1) is around the predetermined floor (13).
It goes without saying that the process is not limited to when the range of m is reached.
