Patent ID: 8085137

Claim:
A brake disk lock having a receiving gap ( 17 ) for the receiving of a brake disk, comprising: a securing section ( 27 , 127 ) for the closing of the receiving gap ( 17 ); an alarm device ( 49 ) for the output of an alarm signal, with the alarm device ( 49 ) having a motion sensor; a movable brake disk recognition device ( 47 ) for detecting whether a brake disk is located in the receiving gap ( 17 ); a pressure switch ( 55 ) having a contact element ( 59 ) which is movable by the brake disk recognition device ( 47 ) against the spring force of a first spring means ( 61 ) and relative to a switch body ( 57 ) of the pressure switch ( 55 ) to activate the alarm device ( 49 ); and an actuation section ( 19 ) which is movable out of a release position into a securing position to close the receiving gap ( 17 ) by means of the securing section ( 27 , 127 ); characterized in that a second spring means ( 69 ) is provided via which the actuation section ( 19 ) is prestressed into the release position, with the switch body ( 57 ) being coupled to the actuation section ( 19 ) via the second spring means ( 69 ), and with the two spring means ( 61 , 69 ) being matched to one another such that, on the movement of the actuation section ( 19 ) into the securing position and on the presence of a brake disk in the receiving gap ( 17 ), the pressure switch ( 55 ) is actuated against the spring force of the first spring means ( 61 ) and a remaining relative movement between the brake disk recognition device ( 47 ) and the actuation section ( 19 ) is compensated by the second spring means ( 69 ).
