Publication number: 20220341218Abstract: Electromechanical lock and method are disclosed. The lock includes: a movable permanent magnet to move between a first position and a second position; a stationary permanent semi-hard magnet; and an electrically powered magnetization coil positioned adjacent to the stationary permanent semi-hard magnet to switch a polarity of the stationary permanent semi-hard magnet between a first magnetization configuration and a second magnetization configuration. The first magnetization configuration of the stationary permanent semi-hard magnet moves the movable permanent magnet to the first position. The second magnetization configuration of the stationary permanent semi-hard magnet moves the movable permanent magnet to the second position. A magnetic axis of the movable permanent magnet is side by side with a magnetic axis of the stationary permanent semi-hard magnet.Type: ApplicationFiled: July 11, 2022Publication date: October 27, 2022Inventors: Mika PIIRAINEN, Väinö TIKKANEN

Patent number: 11408205Abstract: Electromechanical lock. Actuator (103) comprises drive head (109) rotatable by electric power (160). Access control mechanism (104) comprises driven gear (101) with cogs, and grip mechanism (111). Drive head (109) comprises two pins (210, 212) configured and positioned so that one of pins (210, 212) is in notch between two cogs (220, 222, 224, 226, 228) of driven gear (101). For opening, drive head (109) rotates driven gear (101) to open position (400), by two pins (210, 212) driving cogs (220, 222, 224, 226, 228) and overcoming grip mechanism (111), and thereby setting access control mechanism (104) to be rotatable (152) by user. If external mechanical break-in force (172) is applied, drive head (109) remains stationary by at least one of pins (210, 212) contacting at least one of cogs (220, 222, 224), and by grip mechanism (111) holding driven gear (101) stationary in locked position (200).Type: GrantFiled: October 16, 2018Date of Patent: August 9, 2022Assignee: ILOQ OYInventors: Mika Piirainen, Mauri Arvola

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

Publication number: 20160160531Abstract: An electromechanical lock includes an electronic circuit configured to read data from external source and match data against predetermined criterion. An access control mechanism includes a drive gear rotatable by electric power and a driven gear meshable with drive gear. Provided that data matches the predetermined criterion, the drive gear meshes with the driven gear and rotates the driven gear such that the access control mechanism is set to an open state. Provided that an external mechanical break-in force is applied to the access control mechanism, the drive gear remains stationary and the driven gear jams in the drive gear such that the access control mechanism remains in a locked state.Type: ApplicationFiled: June 6, 2014Publication date: June 9, 2016Applicant: iLOQ OyInventors: Mika PIIRAINEN, Mika KELLOKOSKI
