Abstract:
Lock for doors, hoods, tailgates (100), or the like, especially of vehicles such as motor vehicles,with a lock cylinder, the cylinder core (33) of which can be rotated by a properly fitting key (34) out of a neutral position (70), determined by a pulse spring (46), into three different working positions (71, 72, 74), namely, an unsecured position (72), a secured position (71), and a safe-secured position (74);with a handle (10), which, when actuated while the lock is in the unsecured position (72), opens a locking mechanism connected (17, 18) to it, but which cannot actuate the locking mechanism when the lock is in the secured position (71) or in the safe position (74);with at least one microswitch (50, 50'), which, when actuated, controls mechanical or electrical components;and with a switch actuator (42), which is carried along by the cylinder core (33) when the core is rotated (75, 75', 76) by the key, and which, when the cylinder core (33) passes between the neutral position (70) and one of the working positions (71, 72), actuates the microswitch (50);whereinthe switch actuator (42) is seated on a control element (40), which, upon rotation (75, 75', 76) of the cylinder core (33) over different angular ranges by the key, is shifted by control surfaces (41, 51; 24, 25; 81, 82) optionally into one of at least two planes (69, 67, 66) separated by an axial gap (68), namely, into at least a connection plane (69) and a disconnection plane (67);in each of which planes the control element (40) can be moved between a normal position (40) corresponding to the neutral position (70) of the cylinder core (33) and one or more working positions (40', 40"") corresponding to the working positions (71, 72, 74) of the cylinder core (33);where the control element, when in the connection plane (69), is connected nonrotatably to the cylinder core (33), and where its switch actuator (42) can contact and actuate the microswitch (50, 50') at small degrees of rotation (75, 75') of the key;whereas, at large degrees of rotation (76), the control element (40) arrives by means of the axial control surfaces (41, 51; 24, 25) in the disconnection plane (67), in which the control element (40) is disengaged from the cylinder core (33), and where its switch actuator (42) now moves past the microswitch (50) on a level a certain distance (68) away, thus leaving the switch unactuated;and in that the pulse spring (46) is always connected to the control element (40) and always tries, in all planes (69, 67) and in all working positions (40', 40""), to move the control element into its normal position (40).
