  • Cable brake for an elevator
    Patent number: 7543690
    Abstract: A cable brake has an electromagnet for selectively releasing a mass to fall down guide rods under the effect of gravity and impact a trigger lever to release a crossbar from a pawl, whereupon pressure springs move a brake plate against a cable strand to halt the cable strand. The pressure springs extend between a first pressure plate at the brake plate and a spaced second pressure plate that can be displaced along a path by a cooperating screw and nut to pre-stress the pressure springs. The pressure springs are relaxed in one end position of the path whereby the crossbar connected to the first pressure plate by a release bar is engaged by the pawl in a starting position.

  • Door with sliding door leaf and with guide means
    Patent number: 7506727
    Abstract: A door with a sliding door leaf has guides that are arranged in the region of an edge of the door leaf. The guides include a belt so aligned that it extends by the belt length thereof longitudinally of the guide surface for the door leaf in the direction of sliding of the door leaf. When the door leaf is sliding, the belt runs with the door leaf in such a manner that a portion of the belt bears against the guide surface when the door leaf is open, closed and sliding and thereby guides the door leaf.

  • Inputting or adjusting reference positions in a door controller
    Patent number: 7503434
    Abstract: A door controller and a method for inputting or adjusting one or more reference positions into the door controller have the controller connected to a door drive for moving a door and utilize a pulse encoder for monitoring a position of the door and a non-volatile memory for storing the reference position. In a learning mode a control force signal to the drive is reduced. Then the door is moved to the reference position and finally the reference position as recorded by the pulse encoder is registered in the memory of the controller.

  • Safety circuit for lift doors
    Patent number: 7500650
    Abstract: An improved lift system door control or safety circuit utilizes locking devices for the lift shaft doors and lock sensors to monitor the status of the locking devices. The lock sensors are coupled to a lift drive unit control through a data bus, which need not be especially designed as a safety data bus. The lock sensors are repeatedly interrogated at short term intervals. The status of the doors is interrogated on a longer time interval, and such data is also passed to the drive unit control by the data bus. The interrogations are used to determine the operating condition of the locking sensors as well as whether communications or transmission errors are present.

  • Mechanism for indenting a safety gear for an elevator car
    Patent number: 7475756
    Abstract: In relation with this mechanism for stopping an elevator car is, for the monitoring of the speed of the elevator car, an overspeed governor provided which works based on the swing lever principle, whereby the movement of the elevator car will be transferred by means of a governor rope to the overspeed governor. The governor rope extends itself over the entire shaft height and will be returned at the lower shaft end by means of a deflection sheave and stretched by means of counterweight as well as guided at the upper shaft end over a pulley of the overspeed governor. The ends of the governor rope are fastened on a release mechanics arranged on the elevator car and such release mechanics operates in an emergency a safety gear arranged on the elevator car. With the overspeed of the elevator car a rope brake is released upwards.
