JPH0797166A - Door opening and closing width varying device for elevator - Google Patents

Abstract

PURPOSE: To shorten door opening/closing time required when a small number of passengers get on and off by setting door opening/closing width to full opening on the basis of a press-down signal of a first hall button, and setting door opening/closing width to be narrower than full opening on the basis of a press- down signal of a second hall button or a car button. CONSTITUTION: A full opening hall button 3 and a half opening hall button 4 are provided side by side on a wall 2 of a landing 1, and a half opening button is fitted to a car control panel in a car. When the full opening hall button 3 and half opening hall button 4 are pressed, a press-down signal is outputted to a control panel 15. Upon the input of the press-down signal of the full opening hall button 3, the opening/closing width of a door 21 is fully opened, whereas upon the input of the press-down signal of the half opening hall button 4 when one or a small number of passengers are waiting for a car at the landing, the opening/closing width of the door 21 is controlled to be half opened. Door opening/closing time is therefore shortened to improve the operating efficiency of an elevator.

2. Description of the Related Art Conventionally, a hall button for calling a car is provided at an elevator hall. When you press the hall button, a car call is generated. When the car arrives at the landing, the landing and car doors open. Passengers waiting at the landing board the car, and then the door is closed and the car departs.

[0003]

When the car arrives at the landing by pressing the hall button, the door is fully opened. At this time, the door must be fully opened even if the number of passengers waiting at the landing is small. ing. By the way, in the case where the number of passengers is small as described above, the passengers have completely boarded the car during the period from the opening of the door to the half-opening. However, even after the passengers have boarded, the door opens halfway to full opening. For this reason, from the time when the door is fully opened to the time when the door is fully opened, it is an unnecessary time since the boarding is completed, and extra time is wasted. Therefore, there is a problem that the operation efficiency of the elevator is reduced.

The present invention provides a door opening / closing width varying device for an elevator in which the opening / closing width of the door is narrower than the full opening so that extra time is not wasted when there are few passengers waiting at the hall. To aim.

[0005]

In order to achieve such an object, according to the present invention, a door that is openably and closably disposed in a car and a landing, an opening and closing means that opens and closes the door, and a car. To open the door to the hall, the first hall button and the second hall button provided in the hall, the car button provided in the car, and the opening / closing width of the door is fully opened based on the push signal of the first hall button. And a control means for setting the opening / closing width to be narrower than full open based on a pressing signal of the second hall button or the car button and outputting a drive signal to the opening / closing means.

[0006]

[Function] When the number of passengers waiting for a car at the hall is small, the second hall button is pressed. A push-down signal is output from the second hole button to the control means, and a drive signal for half-opening the door is output from the control means to the opening / closing means, and the door is half-opened. At this time, passengers get in, but since it is a small number of people, it is easy to get in, and the door closes immediately after getting in. Therefore, the opening / closing time of the door required when a small number of passengers board the vehicle is shortened.

If the passenger who gets into the car pushes the car button on the car operation panel when getting off the car, the door is opened halfway. At this time, the passenger exits the car and the door closes shortly thereafter. Therefore, the opening / closing time of the door required when a small number of passengers get off is shortened.
