Abstract
The object of the invention is an elevator provided with a safety apparatus arrangement, which elevator comprises at least an elevator car traveling along guide rails and a safety brake device, such as a safety gear, for stopping undesired movement of the elevator car, as well as a transmission mechanism for activating the safety gear. The safety apparatus arrangement comprises a tuning apparatus disposed on the elevator car for detecting a presence on the roof of the elevator car, which tuning apparatus comprises means for pre-activating the transmission mechanism when a presence on the roof of the elevator car has been detected.
Claims20
An elevator comprising:
- an elevator car having a roof, the elevator car configured to travel along guide rails;
- a safety brake device configured to stop unintended movement of the elevator car;
- a transmission mechanism configured to activate the safety brake device if the transmission mechanism is activated, the transmission mechanism including an activation surface;
- and
- a tuning apparatus on the elevator car, the tuning apparatus configured to detect a presence on the roof of the elevator car, and to activate the transmission mechanism by moving a portion of a pretuning plate from a position not on top of the activation surface to a position on top of the activation surface if the presence on the roof of the elevator car has been detected.
A safety apparatus of an elevator, the elevator including at least an elevator car configured to travel along guide rails, the elevator car including a roof, and a safety brake device configured to stop movement of the elevator car, and a transmission mechanism configured to activate the safety brake device, the safety apparatus comprising:
- a tuning apparatus on the elevator car, the tuning apparatus configured to detect a presence on the roof of the elevator car, and to activate the transmission mechanism by moving a portion of a pretuning plate from a position not on top of an activation surface of a transmission mechanism to a position on top of the activation surface of the transmission mechanism if the presence on the roof of the elevator car has been detected.
A safety apparatus arrangement installable in an elevator, the elevator including an elevator shaft, guide rails inside the elevator shaft and an elevator car configured to run on the guide rails, the safety apparatus arrangement comprising:
- a safety brake device configured to stop movement of the elevator car;
- and
- a transmission mechanism configured to activate the safety brake device based on the transmission mechanism being activated and the elevator entering a safety space, the transmission mechanism including an activation surface extending in a first direction, the transmission mechanism being configured to be activated when a portion of a pretuning plate extending in a direction perpendicular to the first direction is moved from a position not on top of the activation surface to a position on top of the activation surface of the transmission mechanism.
