Problems solved by technology

But the downside is that this costly resistor has to be used
In addition, it is disadvantageous that the braking is independent of the position of the door leaf, which in the event of a power failure with the elevator doors at least partially open can result in excessively long closing times

Embodiment Construction

[0021] figure 1 The elevator door 2 of the elevator installation is shown in the open position with a device 3 for preventing overspeeding of the door leaf 4 caused by the force store 6 . The device 3 comprises a door operator 16 , a door operator 12 and a door leaf 4 , wherein the door operator 12 is coupled to the door leaf 4 by means of a coupling device 18 . The door leaf 4 can be moved between an open position and a locked position, preferably horizontally. The door drive 12 can be arranged, for example, on an elevator car of an elevator installation, wherein the illustrated door leaf 4 can be a component part of a shaft door. In this case, the coupling device 18 additionally comprises the known car door-shaft door coupling. In the case of normal power supply, usually both the door controller 16 and the door driving device 12 are powered by the power supply 22 . The device 3 also includes a force accumulator 6 which is coupled or connectable to the door leaf 4 . The f...

Abstract

The invention relates to a device for preventing overspeeding of a door leaf (4) caused by an accumulator (6). The device includes: a door leaf (4) capable of moving between an open position and a locked position; and a door leaf (4). (4) A connected energy accumulator (6) which supplies energy for the closing movement (SB) of the door leaf (4) in the event of a power supply failure; the door drive (12), which The driving device is connected to the door leaf (4), wherein in the door driving device (12), when the door leaf (4) performs a closing movement, electric energy can be induced; a door controller (16) that controls the door driving device (12) , the door controller is suitable for adjusting the movement speed (V) of the door leaf (4), wherein the door controller (16) can operate with the help of induced electric energy when the power supply fails; the invention also relates to a A method for operating an elevator door (2) and a corresponding elevator door.

Description

technical field [0001] The invention relates to a device for preventing overspeeding of a door leaf, which can be used in an elevator system, by a force store. The invention also relates to a method for operating an elevator door and a corresponding elevator door. Background technique [0002] The elevator installation comprises a plurality of shaft doors and a car door, wherein the shaft door and the car door each have a door leaf. When the car door is coupled to the shaft door, the shaft door can be opened or closed by means of a door drive arranged on the car door. Usually, a door closing device is arranged on each shaft door in order to close or keep the shaft door closed at any time by means of a closing force. [0003] In the event of a power failure, the door closing device closes the open shaft door and possibly also the car door connected to the shaft door. Since the holding torque of the door drive is no longer available here, the acceleration forces caused by t...
