Device for actuating lift doors

Abstract

A device for actuating an elevator door comprising: moving means (2) for moving a car door (3) supported by a car (4) of an elevator; and at least one coupling device ( 5) for coupling between the car door (3) and the landing door (6), the coupling device is suitable for transmitting the command from the inactive state to the active state, wherein the coupling device is suitable for making the car The car doors (3) are mutually integral with the landing doors (6) corresponding to the floors at which the cars (4) stop and vice versa, the moving means (2) comprising at least one first flexible element (7) for transmission , the first flexible element is functionally connected to the car door (3) and extends between the first guide wheels (8a, 8b), so that at least one of the first guide wheels is driven by a motor, wherein, by means of the transmission of the first Two flexible elements (9) allow the coupling device (5) to be actuated between an inactive state and an active state.

Description

technical field

[0001] The invention relates to a device for actuating an elevator door. Background technique

[0002] Elevators are known to be provided with car doors which allow access to the car moving along the elevator shaft and are operated automatically by means of actuators mounted on the car itself to open or close the car door , and together with landing doors on each floor allow access to the lift shaft.

[0003] Typically the car door actuating device comprises a carriage which is integral with the car door and which can be actuated so as to slide along a linear guide by means of a flexible element consisting of a belt having mutually parallel axes Extends between pairs of wheels in which one wheel is idling while the other is motor actuated.

[0004] Specifically, when the car stops at a floor, the car doors are coupled to the corresponding landing doors such that actuation of the opening of the car doors results in also pulling the opening of the landing doo...

Examples

Embodiment Construction

[0029] Referring to the drawings, a device for actuating elevator doors according to the invention, generally designated by reference numeral 1, comprises moving means 2 for moving a car door 3, which may comprise one or more leaves.

[0030] The mobile device 2 is supported by a car 4 of the elevator, conveniently at a beam 4 a arranged above the opening for entering the car 4 , which is designed to be closed by a car door 3 .

[0031] Furthermore, there is at least one coupling device 5 which allows the car door 3 to be coupled to a landing door 6 closing the opening for access to the elevator shaft at different floors of the building, and at each floor, a floor Station doors can also be provided with one or more leaves.

[0032] Specifically, the coupling device 5 is capable of switching commands from an inactive state (eg, figure 1 and Figure 6 shown) passed to the active state (for example, figure 2 and Figure 7 ), wherein it is adapted to make the car door 3 integ...
