Patent number: 11225397Abstract: A safety device for an elevator system may include a safety element that in a release position holds a safety system in a deactivated state and in a blocking position activates the safety system. The safety element may exert a driving force configured to transfer the safety element from the release position into the blocking position. A holding element may exert a holding force on the safety element that counteracts the driving force to hold the safety element in the release position. In the release position of the safety element, the holding force exceeds the driving force by a tolerance amount that is adjustable depending on different operating modes that are possible in the release position of the safety element. The safety device may be configured to transfer the safety element into the blocking position, to reduce the holding force such that the driving force exceeds the holding force.Type: GrantFiled: May 8, 2018Date of Patent: January 18, 2022Assignee: TK Elevator Innovation and Operations GmbHInventor: Christian Schulz
