Bottom guiding device for elevator car and landing doors

Abstract

The bottom guiding device according to the invention for telescoping elevator car and/or landing doors with at least one fast-moving door () and one slow-moving door () moving parallel to and within a small distance from a threshold plate () of a car and/or landing door respectively, is characterized in that it implements a threshold plate () on the car and/or landing side, formed with at least one lower edge parallel to the travel path of the doors () and forming a bottom guide track () for the doors; a bottom plate () integral with the slower door () and extending with a small clearance below the faster door (), provided on the threshold side with a guide track () parallel to the travel path of the doors () and accommodating a guide element () integral with the faster door () and close to its rear lower end; at least two distant guide elements () integral with said bottom plate () on the slower door and accommodated on said () on the threshold plate so as to slide freely; and at least one guide element () integral with the faster door () and accommodated on said guide track () on the threshold plate, arranged substantially at the front end of the faster door () and sufficiently far from said guide elements () on the slow door () when the doors are opened and face each other.
