  • Safety equipment for preventing an elevator car collision with an object
    Patent number: 7980362
    Abstract: Safety equipment for an elevator installation with an upper elevator car and a lower elevator car, which cars are both movable substantially independently along a vertical direction in a common elevator shaft of the elevator installation includes a first electro-optical detection system with a first light source in a lower region of the upper elevator car and with a first detector which comprises a light-sensitive first sensor region in an upper region of the lower elevator car. The first light source issues a focused first light beam at a first angle with respect to the vertical direction. The first angle is predetermined such that on approach of the upper and the lower elevator cars the first light beam is incident on the first sensor region and thus is detectable by the first detector. In this case, the first detector triggers a reaction.

  • Method of Operating Elevators During Emergency Situations
    Publication number: 20110155516
    Abstract: An elevator system having at least two elevators, wherein at least one of the elevators is designated as an emergency personnel elevator, can be operated to allow a firefighter to commandeer a second elevator for the purpose of ferrying persons to a safe evacuation floor. The elevator system is configured to determine if a request for an evacuation elevator originates from the firefighter elevator car positioned at one of several floors of a building. In response to the request, an elevator car other than the emergency personnel elevator car is designated as the evacuation elevator car. Further, the evacuation elevator car is dispatched to the floor the emergency personnel elevator car is positioned, and the evacuation elevator car is dispatched to a predefined evacuation floor upon receipt of an evacuation request made by the firefighter.

    Abstract: A system for security control and/or transportation of persons with an elevator installation and a method of operating this system. By means of the system, a person is identified from at least one identification code and from at least one authentication signal. For this purpose, an identification code is entered and/or transmitted by the person, and an authentication signal of the person is captured. Assigned to the identification code and the authentication signal is at least one user profile. An access authorization stored in the user profile, and/or a pre-defined travel destination in the user profile, is/are determined. The authentication signal is checked against at least one reference stored in a user profile. If an access authorization to a travel destination is present, and if the authentication signal and reference correspond, a command signal is transmitted to an elevator installation.

  • Brake device for an elevator with monitoring capabilities
    Patent number: 7909145
    Abstract: An elevator drive has a brake device with compression springs to actuate brake levers, and brake linings on a brake drum creating a braking force. A sensor is provided to detect the movement of a brake magnet armature tappet. A bracket is attached to the brake magnet tappet on one end and a distance piece carrying the sensor housing is arranged on the other end. A restoring lug is attached to the existing mechanical indicator. A monitor evaluates the sensor signal and turns off the elevator drive in the event of dangerous operational states via a safety circuit. The system allows the state of the brake device to be monitored. The more the brake linings wear off due to abrasion, the smaller the distance between the armature and the brake magnet housing. If the armature is in contact with the brake magnet housing, the braking ability of the brake linings is completely void.

  • Brake device of an elevator car
    Patent number: 7905328
    Abstract: A brake device of an elevator car with a brake unit that is mounted on the elevator car. The brake drive includes a flexible tension member that passes around two tension-members reversing-sheaves. One end of the tension members extends parallel to the travel path of the elevator car and is coupled to an actuating element of the brake unit, and thereby also to the elevator car, so that in normal operation the tension member moves synchronously with the elevator car. A blocking device, at least on overspeed of the elevator car, brakes the tension member, as a consequence of which the tension member, via the actuating element, activates the brake unit. A monitoring device detects failure of the coupling between the tension member and the elevator car.
