Title: Closing device with a rotor which has spring-loaded locking mechanisms in a stator, especially for vehicles
IPC: E05B29/10
Filed: 2000-10-17
Abstract: The invention relates to a closing device (10) with a rotor (11) which has a cylindrical periphery (17) and which accommodates spring-loaded locking mechanisms on one side. With a closing device of this type, a pivoting tilting moment of the locking mechanisms may occur. A stator (21) for rotationally mounting the rotor (11) has a blocking channel (22) which is delimited by two flanks (23, 24) and into which the end of the spring-loaded locking mechanisms moves when the key is withdrawn, hereby preventing the rotor (11) from turning. The aim of the invention is to render the device more secure against break-in attempts by picking. To this end, there is a widened channel section (40) in the stator (21) on the flank (23) of the blocking channel (22) that is oriented in the direction of the tilting movement (25). When the rotor (11) is moved into a rotation position in the direction of the tilting direction of the locking mechanism following manipulation, the locking mechanism rests on an inwardly pointing support surface provided inside the widened channel section (40) with its end. The locking mechanism therefore projects beyond the periphery of the rotor (11), hereby intercepting any rotation of the rotor (11) back (26) in the opposite direction of rotation from the other flank (24) of the blocking channel (22), resulting from further manipulation.
