- the rotary member 6 for a Releases rotary motion, the rotary member 6 by means of a Not shown spring according to FIG. 1 counterclockwise rotated, whereby the locking piston 12 is released. Then the appliance door can be opened.
- the restart lockout device generally designated 20 in FIG. 2 includes a first actuator 22 which around an axis of rotation 24 is rotatably supported.
- the first actuator 22 has a first end on one side of the axis of rotation 24 26 and a second one opposite the first end 26 End 28 on the other side of the axis of rotation 24th located.
- the first actuator shown in Fig. 2 with solid lines 22 is in a locked position, the a locked state for the restart lock device 20 characterized.
- the first actuator shown in dashed lines 22 is in a release position, the one Release state for the reclosing device 20 are defined.
- the appliance door When commissioning an electrical device where the door lock is used, the appliance door is closed and thereby the locking device 2 from its open position passes into its closed position, the Reclosure lock device 20 in its locked state, i.e. the first actuator 22 is in its locked position.
- a user of the electrical device controls it, for example by operating a switch or button.
- P1 Force on the first end 26 of the first actuator 22 in the direction of arrow P1 Force is exerted, causing the first actuator 22 in its Release position is rotated. This position of the first actuator 22 is detected to the electrical device actually put into operation.
- a switch 30 more precisely a micro button, is used, which at the transition of the first actuator 22 from its locked position released in its release position becomes.
- the signal generated in this way gives a control, not shown of the electrical device that the actuator 22 is in its release position and the electrical Device can be started.
- the first actuator 22 actuates the switch 30 for this purpose, when it goes into its release position.
- the actuation of the switch 30 (alternatively: the release of the Switch 30) generates a signal that controls the electrical Device placed in a state in which the electrical Device cannot be put into operation again or in which operation continues automatically when the Door is closed again. To continue operations further action by the user is required, such as e.g. pressing an on / off switch or button again.
- the door lock shown in Fig. 3 has the locking device 2 from FIG. 1. Only the rotary member 6 is designated here because the rotary member 6, more precisely its movements, for operating the restart interlock device 20 be used.
- an electromagnet 32 is used for the introduction of force described with reference to FIG. 2 into the first end 26 of the first actuator 22 in In the direction of arrow P1, an electromagnet 32 is used. which by means of a component, not shown, for rotation of the first actuator 22 cooperates with the first end 26. If under the above conditions and Sequences of movement, the first rotary member 22 from its locked position is to be brought into its release position, the Electromagnet 32 driven with a pulse, so that with the first end 26 cooperating component of the electromagnet 32 releases the first end 26 when the first actuator 22 is in its release position. This release of the first end 26 allows an unobstructed rotation of the first actuator 22 back to its locked position.
- the pulse control of the electromagnet 32 also the signal generated by the switch 30 to control the Electromagnets 32 are used.

- the spring 34 serving as a detent spring has a detent 40 on.
- a free spring end opposite spring end 36 42 allows an elastic movement of the spring 34 at Changes in position of the first actuator 22nd
- the first actuator 22 is so at its second end 28 designed that the detent 40 in the release position in the second end 28 engages the first actuator 22 in secure the release position. This backup of the first Actuator 22 avoids an undesirable transition in its locked position.
- the spring 34 is also used to move the first actuator Hold 22 in its locked position, taking the notch 40 engages in an end face 44 at the second end 28.
- the first actuator In its locked position, the first actuator contacts 22 with a nose 46 a button 48 of the switch 30. Will the first actuator 22 moves out of the locked position, is the button 48 by means of a spring, not shown Switch 30 brought into a non-actuated position. In response, switch 30 generates a signal that, like described above, an actual commissioning of the electrical Device.
- the door lock also includes a second actuator 50, which is also rotatable about the axis of rotation 24 is. At its end opposite the axis of rotation 24 the second actuating member 50 has an actuating tongue 52 on. Furthermore, there are one on the second actuator 50 Nose 54 and a driver 56 arranged.
- the second actuator 50 fulfills two functions here, namely on the one hand the determination of the position of the locking device 2 and thus the condition of the appliance door and on the other hand, the introduction of force into the second end 28 of the first Actuator 22 to this from its release position to move into its locked position.
- the second actuator 50 When the locking device 2 is locked, i.e. a transition from the open position to the closed position, the second actuator 50 is not by means of a shown spring from the opening position described above brought into a closed position.
- the previous one Switch operated by the nose 54 released, causing a Signal is generated that the device door has closed indicates.
- the for changing the position of the second actuator 50 spring force used, comparable to the spring of the switch 30, by a spring of the cooperating with the nose 54 Switch are generated.
- the second one is located Actuator 50 in its closed position and the locking device 2 in their closed position.
- the first actuator 22 is still as described above in its locked position until it is by means of the electromagnet 32 moved into its release position and there from the Locking spring 34 is secured. After that, the electrical device be put into operation.
- the locking device 2 is brought into its open position, as explained above, the second actuator 50 from its Closed position moved to its open position.
- the driver 56 the first actuator 22 in one Area at the second end 28. This causes the first actuator 22 from its release position in its locked position. That when reaching the locked position of the first actuator 22 generated by the switch 30 Signal is then used to create an unwanted, automatic To avoid restarting the electrical device, when the appliance door is closed again.
