Abstract

PROBLEM TO BE SOLVED: To shorten a span of time ranging from door opening to the closing by installing a door-open holding time setting part which sets up the door-open holding time to be shorter as compared with the open holding time of an ordinary elevator. SOLUTION: Since the setting time of a door-open holding time setting part 4 of control means 1 is a zero second, by way of example, a driving signal is outputted to a door on-off driving gear 6 as equivalent to this zero second, and because of close operation at once at a point of time when a door is fully opened, a door's turnover motion is carried out. At this time, in the case where a door closing button 5 is not operated, a door closing speed is set to be later as compared with the door closing speed of an ordinary elevator by the setting of a first door closing speed setting part 2 of the control means 1, so that the driving signal equivalent to the door closing speed is outputted to the door on-off driving gear 6, whereby a door closing motion is gently carried out. In addition, at a time when the door closing button 5 is operated, the driving signal equivalent to a speed equal to the closing speed of the ordinary elevator is outputted to a door on-off gear 6.

In the first embodiment configured as described above,
When the door close button 5 is not operated, the characteristic shown in FIG. 2 is obtained. When the door close button 5 is operated, for example, FIG.
Are obtained. 2 and 3, the horizontal axis indicates time, and the vertical axis indicates the opening direction door speed and the closing direction door speed.

When the car stops at a predetermined floor, the landing door and the car door open at the same speed as the door opening speed of the normal elevator as shown in FIGS. Since the set time of the holding time setting unit 4 is, for example, 0 second, a drive signal is output to the door opening / closing drive device 6 corresponding to the 0 second, and the door is inverted for the closing operation immediately when the door is fully opened. Is performed. If the door closing button 5 is not operated at this time, as shown in FIG. 2, the door closing speed is set to be slower than the door closing speed of the normal elevator by the setting of the first door closing speed setting unit 2 of the control means 1. Therefore, a drive signal corresponding to the door closing speed is output to the door opening / closing drive device 6, and the door closing operation is performed relatively slowly. Therefore, when an elderly person or the like in the car tries to get out of the car, the person can safely get off without hitting the door.

Also, during the above-described reversing operation from the door opening,
That is, when the door closing button 5 is operated during the closing operation, as shown in FIG.

The first door closing speed setting unit 12 sets the door closing speed in advance to be lower than the door closing speed of the normal elevator, and the first door open holding time setting unit 14 sets the door opening speed. The time to keep the state is set to be shorter than the holding time in the normal elevator, for example, set to 0 second, and the second door open holding time setting unit 15 is set to the same as the holding time in the normal elevator, for example, 5 seconds. Is what you do.

In FIG. 4, reference numeral 5 denotes a door closing button, and reference numeral 6 denotes a door opening / closing driving device, which are as described above. Reference numeral 16 denotes a selection switch for selecting a holding time set by the second door open holding time setting unit 15, which is electrically connected to the control means 1.

Also in this second embodiment, when the car stops at a predetermined floor, the landing door and the car door open at a speed equal to the door opening speed of the normal elevator as shown in FIGS. At this time, when the selection switch 16 is not operated, the control is performed by the set time of the first door open holding time setting unit 4. That is, since the set time is 0 second, a signal for instructing the door opening / closing drive device 6 to close the door is issued from the control means 11 immediately after the door is fully opened. At this time, assuming that the door closing button 5 is not operated, the door closing speed is controlled by the speed set by the first door closing speed setting unit 2, as shown in FIG. That is, the control means 11 is controlled so that the speed is lower than the normal door closing speed.
, A drive signal is output to the door opening / closing drive device 6, and the door closing operation is performed relatively slowly. Therefore, passengers in the car can safely get off without hitting the door.

When the selection switch 16 is operated during the operation of opening the door, the operation is controlled by the set time of the second door open holding time setting unit 15.

That is, the holding time equivalent to the holding time of the normal elevator is counted from the time when the door is fully opened,
Thereafter, the control means 11 outputs a signal for instructing the door opening / closing drive device 6 to close the door. As a result, the door opening / closing drive device 6 operates, and the door closing speed is maintained at the speed set by the first door closing speed setting unit 2, that is, at a relatively low speed.

When the door closing button 5 is operated during such an operation, as shown in FIG. 6, the door closing speed is set by the second door closing speed setting unit 2, that is, the normal elevator. A speed equivalent to the door closing speed is selected, and a corresponding drive signal is output from the control means 11 to the door opening / closing drive 6, and the door is closed relatively quickly.

In the second embodiment configured as described above,
In addition to having the same operation and effect as the first embodiment described above,
It is possible to lengthen the time during which the door is opened only during a predetermined time period during which congestion is expected, such as during a rush hour.
