Patent number: 10107010Abstract: A lock includes a housing and a lock mechanism with a dead-bolt disposed in the housing, wherein the dead-bolt is retractable and protrudable between its two terminal positions. The lock further includes at least one bending element disposed in the housing connected to a mechanical component of the lock mechanism at a connecting location, wherein the longest extension of the bending element is defined along a first axis. When the dead-bolt retracts and protrudes, the connecting location of the mechanical component moves along a second axis. The first axis is angled with regard to the second axis, such that when the dead-bolt is displaced into at least one terminal position, the bending element elastically bends and the bending element maintains the lock mechanism in the terminal position.Type: GrantFiled: January 20, 2016Date of Patent: October 23, 2018Assignee: DORMA DEUTSCHLAND GMBHInventors: Kai Gröne, Oliver Gendig, Peter Marczinzik
