20080229793 | Schliebetazylinder Mit gesperrter Knaufwelle - The invention concerns a lock cylinder with a lock cylinder housing, having at least one hollow cylindrical receptacle, in which a rotating part is mounted to rotate, which is connected to rotate in unison with a lock element, and with at least one coupling device, which moves at least one blocking element between a locked position, in which it is engaged with an abutment in the rotating part or the lock cylinder housing and blocks rotation between the rotating part and blocking cylinder housing, and a released position, in which it is disengaged from the abutment and permits rotation between the rotating part and the lock cylinder housing. According to the invention, it is proposed that along the peripheral region of the rotating part of the lock cylinder housing, which is swept by the blocking element during one revolution of the rotated part, at least two and preferably several abutments are provided in the peripheral direction, into which the blocking element can engage. | 09-25-2008 |
20080216530 | Modular electromechanical lock cylinder - The invention concerns a lock cylinder with a lock cylinder housing, in which a knob shaft, rotatable by means of a knob, is mounted to rotate on one side or both sides, and with at least one electromechanically operating coupling device, which, based on an authorization signal, connects a lock element to rotate in unison with the knob shaft and/or releases the knob shaft, in order to operate a lock, said authorization signal being generated by an evaluation electronics based on an input or input signal. According to the invention, it is proposed that at least one reading unit with an input unit to record the input and/or receiving unit to receive the input signal is present, that the reading unit with the input and/or receiving unit is arranged spatially separated from the evaluation electronics in at least one knob, that the knob is connected electrically and mechanically releasable to the knob shaft, and that the reading unit generates, from the input or input signal, an access signal that can be evaluated by the evaluation electronics. | 09-11-2008 |
