Patent number: 8186192Abstract: Disclosed is a rotary lock cylinder including a blocking element that engages into the rotor in a closed position while releasing the rotor in an open position. An actuator can be controlled in accordance with data located on the key. In order to displace the blocking element from the closed position into the open position, a latch element is provided which can be moved along with the key. The blocking element can be attached by means of the actuator. The energy required for moving the blocking element is supplied by the user when introducing the key into the key duct such that the load on the power source used for actuating the actuator is minimal.Type: GrantFiled: May 6, 2011Date of Patent: May 29, 2012Assignee: Keso AGInventors: Martin Spycher, Urs Oechslin, Bruno Vonlanthen, Marcel Kölliker, Dieter Peier

Patent number: 7181937Abstract: The locking cylinder has a basic code which can be changed using at least one change key (17, 17?). A rotor (3) is mounted in a cylinder housing (2a, 2b) and has a keyway (4) into which a shank of a standard key which is provided with control surfaces 18 can be pushed in order to position the tumblers which are arranged in three first rows (A, B, C). Further tumblers have coding elements (13) which are arranged in further bores in the cylinder housing (2a, 2b) in a programming position of the rotor (3). The change key (17, 17?) interacts with three further rows (D, E, F) of tumblers in the programming position, these tumblers being arranged in slides. These further rows (D, E, F) each contain tumblers having coding elements (C). The locking cylinder can be produced with a smaller outside diameter and be installed in a particularly cost-effective manner.Type: GrantFiled: June 15, 2005Date of Patent: February 27, 2007Assignee: Keso AGInventor: Ernst Keller

Patent number: 4030325Abstract: A mechanical lock comprises a cylindrical stator, a main rotor constituting the lock cylinder and being mounted for rotation in the stator and an auxiliary rotor mounted in the main rotor. A key carrying information can be inserted into the keyhole of the main rotor and turned to rotate the same between angular positions corresponding to an open and closed lock position through an intermediate latched position. A differential drive couples the auxiliary rotor to the main rotor for effecting relative rotational movement thereof. Key information sensing elements sense the key information during the relative rotational movement of the auxiliary rotor and are repositioned thereby, and these elements are taken along by the main rotor rotation at the end stage of the relative movement to remove them from contact with the key and return them to a rest position.Type: GrantFiled: April 22, 1975Date of Patent: June 21, 1977Assignee: KESO AGInventor: Kurt Ehrat
