Patent ID: 8534102

Claim:
A lock device comprising: a housing ( 2 ) which includes an opening ( 4 ); a core ( 10 ) which is rotatably mounted in the opening ( 4 ) and which includes a key way ( 12 ) for reception of a key ( 60 ); a latching element ( 20 ; 120 ) which co-acts between the housing ( 2 ) and the core ( 10 ) and which is movable between a release position in which the core is rotatable relative to the housing, and a latching position in which rotation of the core relative to the housing is blocked; an electronically controllable actuator ( 30 ; 130 ) which is mounted in the core ( 10 ) and which is movable between an opening-registering position in which movement of the latching element ( 20 ; 120 ) to the release position is permitted, and a latching position in which movement of the latching element to said release position is blocked; and a returning means ( 50 ; 150 ) which co-acts mechanically with the key and with the actuator and functions to move the actuator from the opening-registering position to a further latching position in response to withdrawal of the key from the key way wherein the further latching position prevents movement of the latching element ( 20 ) to said release position, characterized in that the returning means ( 50 ; 150 ) is rotatable and arranged to be rotated by contacting the key as the key is inserted into the key way.
