Patent number: 10443269Abstract: Electromechanical lock utilizing magnetic field forces. An actuator is moved between a locked position and an unlocked position. In the locked position, a first permanent magnet directs a first magnetic field exerting a pushing force so that rotation of the first axle is blocked, and a second permanent magnet directs a second magnetic field exerting a pulling force so that the first axle is kept uncoupled with the second axle. In the unlocked position, the first permanent magnet directs a reversed first magnetic field exerting a pulling force so that the first axle is released to rotate, and the second permanent magnet directs a reversed second magnetic field exerting a pushing force so that the first axle becomes coupled with the second axle.Type: GrantFiled: July 11, 2016Date of Patent: October 15, 2019Assignee: ILOQ OYInventors: Mika Piirainen, Mika Pukari
